  By the way, in the magnetic particle removing apparatus using the magnetic attraction force of the magnet member as described above, it is preferable to increase the magnetic attraction force by increasing the number of magnets in order to improve the removal efficiency of the magnetic particles. .

  However, when the magnetic attractive force is increased in this way, the magnetic particles attracted to the attracting surface become too strong, and as a result, the magnetic particles scraped by the scraping plate are attracted again to the attracting surface and become magnetic. There exists a problem that the removal efficiency of particle | grains falls.

  The present invention has been made in view of such a point. The object of the present invention is, for example, an adsorption surface that adsorbs magnetic particles in a fluid to be treated by a magnetic attractive force, and an adsorption surface that adsorbs the magnetic particles.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each of the following embodiments, components having functions similar to those of the other embodiments are denoted by the same reference numerals, and description thereof is omitted as appropriate.

(Embodiment 1)
FIG. 1 shows a fluid purification system 100 to be processed according to Embodiment 1 of the present invention. In the present embodiment, as an example, the system 100 is applied to a coolant system (fluid to be processed) purification system for a machine tool 101. An example is shown.

  In other words, the fluid purification system 100 to be treated is made up of chips (magnetic particles j) mixed in a coolant liquid (that is, fluid to be treated) or a welded product of the chips and abrasive grains in the machine tool 101. This is applied to the case where the magnetic particles j (see FIGS. 5 and 14) and the coolant liquid are separated, and the magnetic particles j are separated and recovered. More specifically, the system 100 includes a dirty tank 102, a dust separation tank 103, a cyclone supply storage tank 109, a cyclone separation / removal device 1, a magnetic particle removal device 50, and a super clean tank 104. And.

  The dirty liquid discharged from the machine tool 101 (the fluid to be processed before the magnetic particles j are removed) is first introduced into the dirty tank 102 and stored. The fluid to be treated stored in the dirty tank 102 is pumped up by the pump 115 and guided to the dust separation tank 103. In the dust separation tank 103, a relatively large dust that is adsorbed by a magnet plate 108f, which will be described later, or quickly settled by its own weight is removed, and the fluid to be treated including the remaining dust is stored in the cyclone supply storage tank 109. Is done.

  The fluid to be treated stored in the cyclone supply storage tank 109 is pumped up by the pump 105 and guided to the cyclone separation and removal apparatus 1. In the cyclone separation / removal apparatus 1, as will be described later, after the magnetic particles j having a relatively small specific gravity are discharged from the floating material discharge port 21 (see FIG. 5) to the dust separation tank 103, the specific gravity is relatively large. The magnetic particles j are separated by centrifugal force and discharged from the discharge port 4 (see FIG. 5) to the dust separation tank 103, and the treated fluid after purification is discharged from the cylindrical discharge pipe 6 to be magnetic particles. Guided to removal device 50.

  In the magnetic particle removal device 50, the fluid to be treated containing the magnetic particles j that could not be removed by the cyclone separation / removal device 1 is separated and returned to the cyclone supply storage tank 109, while the fluid to be treated after the purification treatment Is discharged into the super clean tank 104. In FIG. 1, reference numeral 106 denotes an ejector valve (corresponding to a suction means) for sucking the magnetic particles j separated by the magnetic particle removing device 50 as will be described later.

  The clean fluid to be treated after removal of magnetic particles, which is guided and stored in the super clean tank 104, is supplied to the machine tool 101 by a pump (not shown) and used as a coolant. The fluid to be treated in the super clean tank 104 is returned to the cyclone supply storage tank 109 from the return pipe 104b when the water level reaches a predetermined water level h2. Along with this, the dust that is light and floats on the surface in the super clean tank 104 is also returned to the cyclone supply storage tank 109. Further, dust that has not been removed by the magnetic particle removing device 50 and has settled in the super clean tank 104 is discharged to the dirty tank 102 via a discharge pipe 104c provided at the bottom of the super clean tank 104 and a discharge valve 104d. It has become so.

  As described above, the fluid to be processed discharged from the machine tool 101 is not directly supplied to the cyclone separation / removal device 1, but is supplied after relatively large dust is removed by the dust separation tank 103 once. Since the fluid to be processed containing smaller dust becomes the object of centrifugation, the removal efficiency of relatively small magnetic particles j in the cyclone separation / removal device 1 can be easily increased. Further, by combining the magnetic particle removing device 50, the removal efficiency of smaller magnetic particles j can be increased. That is, for example, the characteristics of each device can be specialized in accordance with the properties of the dust, etc., and the overall removal efficiency for various sizes of dust can be greatly increased.

  The above system configuration example is an example, and various modifications can be made. For example, the fluid to be processed discharged from the machine tool 101 is not limited to being supplied to the dust separation tank 103 via the dirty tank 102 but may be directly supplied to the dust separation tank 103. The fluid to be treated discharged from the dust separation tank 103 is not limited to being supplied to the cyclone separation / removal device 1 after being stored in the cyclone supply storage tank 109, but is directly supplied from the dust separation tank 103. You may be made to do. However, when the dirty tank 102 and / or the cyclone supply storage tank 109 are provided before and after the dust separation tank 103 as described above, the inflow and outflow amounts of the dust separation tank 103 are appropriately set or controlled. Thus, it becomes easier to improve the dust removal efficiency. In addition, the magnetic particles j and floating substances discharged from the cyclone separation / removal device 1 are normally returned to the dust separation tank 103, but can be easily recovered into the dust box 107 and the floating substance collection box 103m. However, the present invention is not limited to this, and may be returned to the dirty tank 102 or the cyclone supply storage tank 109 or may be separately separated, and finally dust and the like can be collected. I just need it.

-Configuration of dust separation tank 103-
The dust separation tank 103 has a configuration as shown in FIGS. The fluid to be treated that flows in from the inflow pipe 103a flows into the tank body from the tank inlet 103c, wraps around the inlet partition plate 103j, and passes between the outlet lower partition plate 103g and the outlet side partition plate 103h. Thus, the gas is discharged from the discharge pipe 103b.

  A magnet 103d and a magnet plate 108f are provided in the vicinity of the path through which the fluid to be treated flows, and dust (magnetic particles) is forcibly adsorbed, precipitated and trapped in addition to being settled by its own weight. It has become so. The dust trapped by the magnet 103d in the vicinity of the tank inlet 103c rolls down and settles in the tank, or can be forcibly discharged from the chip discharge port 103e. The chip discharge port 103e is closed with a lid 103f during normal operation.

  On the other hand, the dust adsorbed by the magnet plate 108f or settled in the tank is discharged to the dust box 107 by the conveyor type dust separator 108. The dust separation device 108 includes a drive shaft 108b driven by a motor 108a, a driven shaft 108c, and a chain belt 108d suspended between the two. A scraper 108e is erected on the chain belt 108d at an appropriate interval, and dust that is attracted to the magnet plate 108f or settled in the tank is scraped out by the scraper 108e.

  The dust separation device 108 is not limited, but, for example, it is unitized and is detachably provided so that it can be pulled out obliquely upward so that maintenance can be easily performed. Further, even when the dust separation device 108 is pulled out, the dust or the like that has settled in the dust separation tank 103 can be easily scraped out manually. The dust separator 108 is not limited to the above-described configuration, and for example, devices having various known structures such as those disclosed in Japanese Patent Application Laid-Open No. 2003-251542 may be applied.

  The dust separation tank 103 is also configured to collect magnetic particles j discharged from the cyclone separation / removal device 1, which will be described in detail later, and levitated matter through the collection pipes 121 and 122. The magnetic particles j recovered by the recovery pipe 121 settle on the bottom of the dust separation tank 103 or are adsorbed by the magnet plate 108f and discharged to the dust box 107 by the dust separation device 108 as described above. In the dust separation tank 103, the recovery pipe 122 that collects the floating material is surrounded by the floating material partition plate 103i except for the lower part. As a result, the recovered levitated matter is stopped within the range surrounded by the levitated product partition plate 103i, and is prevented from being mixed into the fluid to be processed sent to the cyclone supply storage tank 109. Yes. When the water level in the dust separation tank 103 rises, the levitated matter is discharged to the levitated matter collection box 103m (FIG. 3).

  Although not an essential component, a monitoring window 103k (FIG. 3) is provided on the side of the dust separation tank 103 for visually checking the internal liquid level.

-Configuration of cyclone separation and removal device-
As shown in FIG. 5, the cyclone separation / removal device 1 includes a cyclone processing container 2 made of a non-magnetic material such as stainless steel, aluminum, or resin, and a floating material collection disposed on the upper side of the cyclone processing container 2. A tank 15 and a cylindrical discharge pipe 6 that discharges the fluid to be treated after purification in the cyclone processing container 2 to the outside of the processing container 2 (outside the cyclone separation and removal apparatus 1) are provided. The cyclonic processing container 2 and the levitated substance recovery tank 15 are composed of a substantially cylindrical main body 2a whose upper end is closed, and a substantially cylindrical fluid eddy current 2e connected to the lower end of the main body 2a. It is configured. More specifically, the inner space 13 of the main body 2a is partitioned up and down by a partition plate 18. The partition plate 18 constitutes the upper wall portion of the cyclone processing container 2, and the levitated material collection tank 15 Constitutes the bottom wall.

  The cyclone type processing container 2 is composed of a tank body in which inverted conical portions 2b and 2d are formed on the inner peripheral side wall surface 2g extending in the vertical direction, and includes a magnetic particle j as will be described later. The magnetic particles j are separated by the centrifugal force by causing the fluid to swirl in the counterclockwise direction when the cyclone separation / removal device 1 is viewed from above along the inner peripheral wall surface 2g. Needless to say, the fluid to be treated may be swirled in the clockwise direction.

  More specifically, the inner peripheral side wall surface 2g of the cyclonic processing vessel 2 is formed at the upper end portion thereof, and a cylindrical portion 2f whose inner diameter is substantially constant over the entire vertical direction, and the cylindrical portion 2f The upper inverted conical portion 2b that is continuously provided on the lower side and has an inner diameter that decreases toward the lower side, and a lower inverted conical portion 2d that is formed adjacent to the upper inverted conical portion 2b on the lower side thereof; It consists of the conical part 2c which connects both reverse conical parts 2b and 2d. The axial center of the cylindrical portion 2f, the opposite conical portions 2b and 2d, and the conical portion 2c are coincident with each other, and this axial center is the central axis 1C of the cyclonic processing vessel 2. The central axis 1C substantially coincides with the turning central axis of the fluid to be processed. The cylindrical portion 2f is a lower portion of the inner peripheral side wall surface of the main body portion 2a than the partition plate 18, and the opposite conical portions 2b and 2d and the conical portion 2c are the fluid vortex portion 2e. The inner peripheral side wall surface.

  As shown in FIGS. 5 and 6, an inlet for introducing a fluid to be processed into the cyclone processing vessel 2 is provided at the upper end of the cylindrical portion 2 f (that is, the upper end of the cyclone processing vessel 2). 3 is formed. The introduction port 3 opens through the cylindrical portion 2f from the tangential direction when viewed from above, and allows the fluid to be processed flowing into the processing container 2 from the opening to the center of the cylindrical portion 2f. It is configured to swirl counterclockwise around an axis (the central axis 1C of the processing container 2) (note that the introduction port 3 does not actually appear in the cross section shown in FIG. For the sake of convenience, it is shown at the position projected on the cross section of FIG. Thus, the fluid to be treated is swirled in the counterclockwise direction in the cylindrical portion 2f, and thus swung in the same direction (counterclockwise direction) in the fluid vortex portion 2e.

  The inner diameter of the upper end of the lower inverted conical portion 2d is larger than the inner diameter of the lower end of the upper inverted conical portion 2b (that is, the diameter is increased). The magnetic particles j are separated and concentrated at the upper end of the portion 2d.

  The upper end of the lower inverted conical portion 2d and the lower end of the upper inverted conical portion 2b are connected via a conical portion 2c whose diameter increases toward the lower side. A discharge port 4 for discharging the magnetic particles j is provided at the lower end of the lower inverted conical portion 2d (that is, the bottom surface of the cyclonic processing vessel 2 (fluid vortex portion 2e)). The fluid vortex portion 2e constituting the both inverted conical portions 2b and 2d and the conical portion 2c is fitted and inserted into the cylindrical outer cylinder 5 so as to be detachable. The cylindrical outer cylinder 5 is made of a nonmagnetic material such as stainless steel or synthetic resin, but may be a steel pipe as long as there is no influence on the action of the magnetic force of the permanent magnet 10. Moreover, although the main-body part 2a and the fluid vortex | eddy_current part 2e are comprised separately, you may integrate.

  The cylindrical outer cylinder 5 is screwed and fixed by screwing a male screw portion 9b formed on the outer peripheral surface of its upper end portion with a female screw portion 9a formed on the lower end portion of the main body portion 2a. Both the outer peripheral edge of the upper end surface of the fluid vortex portion 2e and the inner peripheral edge of the upper end surface of the cylindrical outer cylinder 5 are chamfered, and a V-shaped groove portion is formed by the double-sided chamfered surface. Ring 8 is set. By doing so, the fluid to be processed is prevented from leaking out from the connection portion between the main body portion 2a and the fluid vortex portion 2e. In particular, the upper end portion of the cylindrical outer cylinder 5 is screwed and pressed against the lower end portion of the main body 2a, and the upper end surface of the fluid vortex portion 2e is pressed upward with a spring (not shown) so that assembly and sealing can be performed. Therefore, it is excellent in assembling and maintenance.

  The levitated substance recovery tank 15 is a levitated substance having a relatively small specific gravity (for example, magnetic particles having a low specific gravity, oil components, floating carbon, floating dust, etc.) that floated above the cyclone type processing vessel 2. The bottom wall portion is constituted by the upper wall portion (partition plate 18) of the cyclonic processing vessel 2 as described above.

  The inner peripheral side wall surface 15a of the levitated material collection tank 15 has a cylindrical shape that is coaxial with the cylindrical portion 2f of the cyclonic processing vessel 2, and is formed so that the diameter dimension is substantially constant in the vertical direction. .

  Further, a floating object discharge port 21 is formed on the inner peripheral side wall surface 15a of the floating substance collection tank 15 for discharging the fluid to be processed including the collected floating substance to the outside of the collection tank 15 (outside the apparatus 1). ing. As shown in FIG. 6, the levitated material discharge port 21 penetrates and opens from the tangential direction to the inner peripheral side wall surface 15 a of the recovery tank 15 as viewed from above. More specifically, the levitated material discharge port 21 is formed at a position opposite to the introduction port 3 with the central axis 1C of the cyclonic processing container 2 (the central axis of the recovery tank 15) interposed therebetween. The axial center direction of the floating material discharge port 21 is perpendicular to the axial direction of the introduction port 3.

  On the partition plate 18 constituting the bottom wall portion of the floated material recovery tank 15 (that is, the upper wall portion of the cyclone type processing container 2), the floated material floating above the processing container 2 is put into the floated material recovery tank 15. A recovery through-hole for guiding is formed.

  The recovery through-hole is composed of a plurality of slits 19, and each slit 19 extends radially outward from the center of the cyclone processing container 2 (cylindrical part 2 f) when viewed from above, and the processing container 2. Are arranged at equal intervals (90 ° intervals in the present embodiment) in the circumferential direction around the central axis 1C (the central axis of the cylindrical portion 2f).

  Each slit 19 is formed by notching a portion corresponding to each slit 19 of the partition plate 18 and bending it downward. As shown in FIG. 7, the bent piece 20 which is the bent portion of the partition plate 18 is a guide bent piece 20a for guiding floating objects from the slits 19 into the collection tank 15 (in this embodiment, 3 of the 4 bent pieces 20) and a rectifying fold for rectifying the flow in the vicinity of the lower surface of the partition plate 18 (the flow at the upper end in the cyclone type processing container 2) as shown in FIG. It consists of a piece 20b.

  The guide folding piece 20a has a portion corresponding to the slit 19 of the partition plate 18 on the side edge portion on the swiveling downstream side in the width direction (the downstream side in the swirling direction of the fluid to be treated and on the right side in FIG. 7). (The side edge portion is the base end portion) and the turning upstream side is bent so as to incline downward.

  On the other hand, the rectifying folded piece 20b has a portion corresponding to the slit 19 of the partition plate 18 on the upstream side of the turning direction in the width direction (the upstream side in the turning direction of the fluid to be processed and on the left side in FIG. 8). It is formed by bending along the edge (with the side edge as the base end) so that the swivel downstream side is inclined downward.

  In the embodiment, the guide bent piece 20a and the rectifying bent piece 20b are provided. However, according to the swirl flow vortex forming state, only the guide bent piece 20a is used as the rectifying bent piece 20b. May be omitted.

  The cylindrical discharge pipe 6 (see FIG. 1) extends in the vertical direction through the center of the cyclonic processing container 2 and the levitated substance recovery tank 15 and communicates with the inside and outside of the processing container 2 to communicate with the processing container 2. 2 is configured to guide the clean fluid to be processed in 2 out of the processing container 2 (outside the apparatus 1).

  More specifically, the lower end portion of the cylindrical discharge pipe 6 is positioned in the cyclone type processing container 2 and extends upward from the upper end portion of the processing container 2 (in the partition plate 18). The bottom wall portion of the levitated material collection tank 15) and the upper wall portion (the upper end portion of the main body portion 2a) of the levitated material collection tank 15 are extended outside the processing container 2 (outside the apparatus 1). Yes. In other words, the cylindrical discharge pipe 6 extends in the vertical direction through the central portion so as to skew the floated material collection tank 15. The height position of the opening (hereinafter referred to as the fluid discharge port 7) at the lower end of the cylindrical discharge pipe 6 is substantially the same height as the upper end of the lower inverted conical portion 2d or in the vicinity thereof (for example, the lower reverse) The clean fluid to be treated from which magnetic particles j have been removed is located above the upper end of the conical portion 2d and below the lower end of the upper inverted conical portion 2b. It is guided out of the apparatus 1 from the discharge port 7 through the cylindrical discharge pipe 6. Moreover, the outer peripheral surface of the lower end part of the cylindrical discharge pipe 6 provided with the fluid discharge port 7 is slightly expanded in diameter to the outside, so that the centrifugal force is reliably acted on by the fluid. Yes. However, according to circumstances, the lower end portion may remain the same diameter as the main body portion (a portion excluding the lower end portion) of the cylindrical discharge pipe 6.

  The outer peripheral surface 2h (the outer peripheral surface of the side wall portion 2i) near the upper end portion of the lower inverted conical portion 2d and the lower end portion of the upper inverted conical portion 2b in the cyclone processing vessel 2 (fluid vortex portion 2e) is shown in FIG. As shown in FIG. 9, circumferential grooves 12 and 11 are formed, and eight permanent magnets 10 are fitted therein. Each of these permanent magnets 10 has, for example, a rectangular thin plate shape, and two magnets adjacent to each other in the circumferential direction are connected by a yoke 22. The yoke 22 is formed, for example, by bending a permalloy thin plate. The circumferential positioning of each permanent magnet 10 is made by thin spacers 16 and thick spacers 17 arranged alternately. The yoke 22 is positioned in the circumferential direction by the thick spacer 17. By providing the yoke 22 as described above, the magnetic attractive force by the permanent magnet 10 can be further increased. That is, by arranging the yoke 22 on the outer side in the radial direction of the permanent magnet 10 and connecting two permanent magnets 10 at a time, the lines of magnetic force escaping outward in the radial direction can be reduced, so that it acts on the inner side in the radial direction of the permanent magnet 10. Magnetic force becomes stronger. Therefore, the permanent magnet 10 can be made compact. Further, even if a ferromagnetic material such as an iron member is disposed outside the permanent magnet 10 in the radial direction, the influence of the magnetic attractive force from the permanent magnet 10 on the ferromagnetic material is reduced. For this reason, the design freedom at the time of designing the cyclone type processing container 2 and its peripheral device can be raised.

  In FIG. 9, the thickness of the yoke 22 is drawn thinner than the thickness of the permanent magnet 10. For example, when a neodymium magnet or a samarium cobalt magnet is used as the permanent magnet 10 and a steel plate is used as the yoke 22. The yoke 22 may be set to a thickness equal to or greater than that of the permanent magnet 10.

  Further, in addition to the yoke 22, for example, a similar yoke may be further provided on the outer periphery of the cylindrical outer cylinder 5 so that the suction force can be further increased.

  In each of the permanent magnets 10, both the circumferential grooves 11 and 12 are arranged so that the inner side in the radial direction is the south pole and the north pole is adjacent to each other.

  The method of providing the permanent magnet 10 is not limited to fitting into the circumferential grooves 11 and 12 as described above. For example, a concave portion corresponding to the outer shape of the permanent magnet 10 is formed on the outer peripheral surface 2h of the side wall 2i. It may be inserted. Further, the number of permanent magnets 10 connected by the yoke 22 is not limited to two, and may be larger. Furthermore, the yoke 22 may be formed in a ring shape so that all the permanent magnets 10 are connected. Good. On the other hand, a magnetic body having substantially the same shape as that of the permanent magnet 10 may be provided so as to overlap the back surface of each permanent magnet 10. Further, the permanent magnet 10 is not limited to being provided in two upper and lower stages near the upper and lower sides of the fluid discharge port 7 in the cylindrical discharge pipe 6, and only one of them may be provided.

  The cyclone separation / removal apparatus 1 is not limited to the one having the above-described configuration, and various apparatuses having a centrifugal separation function can be applied. Specifically, for example, an apparatus mainly including the removal of the magnetic particles j by centrifugation may be used without providing the levitated substance recovery tank 15.

-Operation of cyclone separation and removal device-
The separation / recovery operation of the magnetic particles j in the cyclone separation / removal apparatus 1 configured as described above will be described.

  First, the fluid to be processed including the magnetic particles j is introduced into the cyclone processing container 2 from the introduction port 3 (see FIG. 5) at high speed. The introduced fluid to be treated is swirled around the cylindrical discharge pipe 6 along the cylindrical portion 2f of the inner peripheral wall surface 2g of the processing vessel 2 to generate a swirling flow. Here, the levitated matter having a small specific gravity contained in the fluid to be treated is levitated and concentrated on the upper part in the processing container 2 by the buoyancy that causes the levitated matter to levitate. The floated and collected floated material flows into the floated material collection tank 15 from the slit 19 in the process in which the fluid to be processed swirls around the cylindrical discharge pipe 6. More specifically, the levitated matter gathered at the upper end (in the vicinity of the lower surface of the partition plate 18) in the cyclone type processing container 2 is swung from the swirling upstream side to the swirling downstream side together with the processing fluid by swirling flow of the fluid to be treated. In the course of flowing into the collection tank 15, the course is changed upward by colliding with the guide surface 20 j (see FIG. 7) of the guide folding piece 20 a and guided into the collection tank 15. The to-be-processed fluid including the floating material guided into the recovery tank 15 swirls around the cylindrical discharge pipe 6 along the inner peripheral side wall surface 15a in the recovery tank 15 due to the revolving inertia. Then, it is discharged in the tangential direction from the floating object discharge port 21 and guided outside the apparatus 1.

  On the other hand, the remaining fluid that has not flowed into the recovery tank 15 among the fluid to be treated that has flowed into the cyclone processing container 2 from the inlet 3 (that is, the fluid to be treated from which the floating material having a small specific gravity has been removed) The rotational speed is increased toward the lower side after being guided to the inverted conical portion 2b. Along with this, the magnetic particles j in the fluid to be treated move to the radially outer side due to the centrifugal force, and descend while turning along the inner peripheral side wall surface 2g. A large centrifugal force acts on the magnetic particles j in the fluid to be treated at the lower end of the upper inverted conical portion 2b where the rotational speed of the fluid to be treated becomes the fastest, and the upper circumferential groove 11 A magnetic attraction force acting radially outward from the permanent magnet 10 inserted into the magnetic field acts. As a result, the magnetic particles j are separated on the inner peripheral side wall surface 2g side (radially outer side).

  On the other hand, the clean fluid in which the magnetic particles j are extremely reduced remains near the center of the upper inverted conical portion 2b. Here, the reason why it is expressed as a clean fluid in which the magnetic particles j are extremely reduced is that the magnetic particles of 1 μm to 5 μm may be guided to the cylindrical discharge pipe 6 together with the clean fluid because it is light, and slightly magnetic. This is because particles may be contained.

  The fluid to be treated is guided to the conical portion 2c with the magnetic particles j having a size of 5 μm or more being mainly separated toward the inner peripheral side wall surface 2g.

  In the conical portion 2c, although the swirling flow velocity of the fluid to be treated is slightly reduced, the magnetic particles j that are already biased toward the inner peripheral wall surface 2g as described above move further outward in the radial direction.

  Then, when the magnetic particles j in the fluid to be treated that have passed through the conical portion 2c flow into the upper end portion of the lower inverted conical portion 2d, in addition to the flow inertial force outward in the radial direction, In response to a magnetic attractive force directed radially outward from the permanent magnet 10 fitted in the circumferential groove 12, it is separated and concentrated on the upper end portion of the lower inverted conical portion 2 d. The magnetic particles j separated and aggregated at the upper end of the lower inverted conical portion 2d will eventually become a nodule and fall along the inclined surface of the lower inverted conical portion 2d due to their own weight. The discharged magnetic particles j are collected in a dust separation tank 103 (collection container).

  On the other hand, the fluid to be treated that has flowed into the lower inverted conical portion 2d is swirled (vortexed), and an upward axial force is applied to the fluid to be treated at the center so that the fluid is discharged from the fluid discharge port 7 into a cylindrical shape. It is supplied to the magnetic particle removing device 50 through the discharge pipe 6.

  In the above embodiment, the magnetic particles adsorbed on the inner wall of the lower inverted conical portion 2d fall under its own weight, but when further promoting the fall of the adsorbed magnetic particles, a mechanism that weakens the magnetic force of the magnet member, for example, A mechanism for moving the magnet member and / or the yoke up and down may be provided to positively separate and remove.

A scraping member 81 having a shape (see FIG. 14) is provided, and the front side surface of the scraping member 81 in the relative movement direction is the scraping surface 81a. The scraping surface 81a is an inclined surface that is inclined so as to move away from the suction surface 51a toward the rear side in the relative movement direction. The scraping member 81 is made of an acrylic material so as to reduce the sliding resistance between the stainless steel circular plate 51 (suction surface 51a).

-Operation of magnetic particle removal device-
In the to-be-processed fluid purification system 100 configured as described above, to-be-processed including light-weight (1 μm to 5 μm) magnetic particles j discharged from the cyclone separation and removal apparatus 1 and guided to the magnetic particle removal apparatus 50. The fluid flows from the inlet 64a of the device 50 into the device 50. That is, the fluid to be treated that has flowed in from the introduction port 64a flows downward through the guide duct 67 and flows out of the opening 68 at the lower end thereof. The fluid to be treated that has flowed out of the opening 68 flows in the flow path 70 formed between the guide casing 69 and the suction surface 51a from one side to the other side in the tank length direction (FIGS. 10 and 10). 13). Thus, while the fluid to be treated flows through the flow path 70, the magnetic particles j contained in the fluid to be treated receive the magnetic attraction force from the permanent magnet 55 and are attracted to the attracting surface 51a. It will be.

  The magnetic particles j adsorbed on the adsorption surface 51a are scraped and removed by the removal main body 80. That is, when the disk-like suction part 60 is driven to rotate counterclockwise around the shaft 61 by the motor 56, the removal main body part 80 moves relative to the suction surface 51a in the clockwise direction. As a result, the magnetic particles j (see FIG. 14) are scraped off by the scraping surface 81a formed on the front side in the relative movement direction of the scraping member 81 of the removal main body 80. The scraped magnetic particles j are sucked into the recovery space 82 from the particle suction port 83c through the communication path 84 by the suction action of the ejector valve 106, and the sucked magnetic particles j are collected in the surrounding area. Together with the processing fluid, it is guided from the particle discharge port 83g into the magnetic particle discharge pipe 87 and discharged to the cyclone supply storage tank 109 on the downstream side. It may be discharged to the dirty tank 102 or the dust separation tank 103. Thus, the clean fluid to be treated from which the magnetic particles j have been removed is discharged from the opening 71 (see FIG. 10) of the guide casing 69 into the super clean tank 104 and supplied to the machine tool 101.

  As described above, in the first embodiment, the removal main body 80 of the magnetic particle removing device 50 scrapes the magnetic particles j adsorbed on the adsorption surface 51a by the scraping surface 81a and the scraping surface 81a. A housing member 83 for collecting the magnetic particles j. The housing member 83 is formed with a particle suction port 83c and a particle discharge port 83g communicating with the collection space 82, thereby removing the magnetic particles. The apparatus 50 further includes an ejector valve 106 for sucking a fluid to be processed into the recovery space 82.

  Thereby, before the magnetic particle j scraped off by the scraping surface 81a is attracted to the attracting surface 51a again by the magnetic attraction force of the permanent magnet 55, the magnetic particle j together with the surrounding fluid to be treated is collected. It can be removed by suction into the housing member 83 (recovery space 82). Therefore, the removal efficiency of the magnetic particles j as the entire device 50 can be improved.

  In the first embodiment, the removal main body 80 is a plate whose lower surface (lower side surface in the thickness direction) abuts on the suction surface 51a and whose front side surface in the relative movement direction is the scraping surface 81a. A magnetic shield member 86 made of a magnetic material is laminated on an upper surface 81b (upper side surface in the thickness direction) of the scraping member 81.

  As a result, a magnetic attractive force in a direction attracting each other acts on the magnetic shield member 86 and the permanent magnet 55. For this reason, the scraping member 81 sandwiched between the magnetic shield member 86 and the attracting surface 51 a is pressed toward the attracting surface 51 a side (lower side) by the magnetic shield member 86. As a result, the lower surface (surface on the suction surface side) of the scraping member 81 is pressed against the suction surface 51a. Therefore, the edge 81f on the suction surface 51a side (lower side) of the scraping surface 81a can be pressed against the suction surface 51a as much as possible, and this allows the relatively small magnetic particles j to be released without missing. It can be scraped off by the cut surface 81a. Therefore, the removal efficiency of the magnetic particles j can be improved as much as possible.

  In the first embodiment, the magnetic shield member 86 is disposed between the collection space 82 in the removal main body 80 and the adsorption surface 51a. According to this, as a result of the magnetic shield member 86 blocking the magnetic force of the permanent magnet 55, it is possible to prevent the magnetic attractive force from acting on the magnetic particles j attracted in the recovery space 82. Therefore, the fluidity of the magnetic particles j in the recovery space 82 can be sufficiently ensured. For this reason, it is possible to reliably prevent the collection efficiency of the magnetic particles j from being reduced due to the accumulation of the magnetic particles j in the collection space 82 or the block of the particle suction port 83c with the deposited magnetic particles j. be able to.

  In the first embodiment, the particle suction port 83c is formed on the front side surface 83k of the housing member 83 in the relative movement direction, and the scraping surface 81a of the scraping member 81 is located at the rear side in the relative movement direction. The rear end of the scraping surface 81a in the relative movement direction is on the suction surface side (lower side) of the particle suction port 83c. It is connected to the edge.

  According to this, the magnetic particles j scraped by the scraping surface 81a can be guided to the particle suction port 83c along the scraping surface 81a. Therefore, the magnetic particles j can be reliably guided and collected in the collection space 82 from the particle suction port 83c.

  In the first embodiment, the housing member 83 has the through-hole 83b coaxially with the recovery space 82 (cylindrical hole). By doing so, the fluid to be processed flowing from one side to the other side in the longitudinal direction of the tank in the flow path 70 flows from the through pore 83b through the recovery space 82 to the particle discharge port 83g. Thereby, the fluidity of the fluid to be processed (magnetic particles j) in the recovery space 82 can be enhanced. Therefore, the recovery efficiency of the magnetic particles j into the recovery space 82 can be further improved.

  Further, in the first embodiment, on the upper side of the cyclone-type processing container 2, a floated material recovery tank 15 having a bottom wall portion constituted by the upper wall part (that is, the partition plate 18) of the processing container 2 is provided. The partition plate 18 is formed with slits 19 (collection through holes) for guiding the floated material into the collection tank 15.

  In this way, before the fluid to be treated that has flowed into the processing container 2 is subjected to the centrifugal separation process in the fluid vortex section 2e, the magnetic particles j having a small specific gravity contained in the fluid to be treated are removed from the upper part of the processing container 2. And can be led from the slit 19 into the float collection tank 15. Therefore, it is possible to surely remove the levitated matter having a small specific gravity that cannot be removed by the centrifugal separation process in the fluid vortex portion 2e, and the removal efficiency of the levitated matter and the magnetic particles j in the entire apparatus 1 can be improved. .

  Further, in the first embodiment, the guide folding piece 20a and the rectifying fold formed by cutting the portion corresponding to the slit 19 of the partition plate 18 on the lower surface of the partition plate 18 and bending it downward. A bent piece 20b is provided, and the guide bent piece 20a is formed so as to incline to the upstream side of the turn as it goes downward from its base end. As a result, the levitated matter that has floated above the cyclone type processing vessel 2 can be reliably and easily guided into the levitated matter collection tank 15 along the guide surface 20j of the guide folded piece 20a.

  Further, the rectifying bent piece 20b is formed so as to incline to the downstream side of the turn as it goes downward from its base end. As a result, the fluid to be processed in the vicinity of the lower surface of the partition plate 18 can be rectified by pressing the turbulent flow caused by colliding with the guiding folded piece 20a by pressing the lower surface 20k of the rectifying folded piece 20b. it can. Therefore, it is possible to prevent the behavior of the floating object from being disturbed due to the disturbance of the flow of the fluid to be treated. As a result, the floating object is removed from the floating substance collection tank 15 by the bent piece 20a for guiding. You can be surely guided in.

  Further, in the first embodiment, the inner peripheral side wall surface 15a of the levitated material recovery tank 15 has a substantially cylindrical shape that is formed substantially coaxially with the cylindrical portion 2f of the cyclonic processing vessel 2, and has a cylindrical discharge pipe. 6 is extended in the up-down direction through the center part so that the float collection tank 15 may be skewered.

  By doing so, the fluid to be treated that has flowed into the recovery tank 15 from the slit 19 can be swirled around the cylindrical discharge pipe 6 while maintaining its swirling inertia. Therefore, the fluid to be treated in the recovery tank 15 becomes a fluid resistance to reliably prevent the flow of the fluid to be processed (and hence the magnetic particles j) from the slit 19 into the recovery tank 15. Can do.

  Moreover, in the said Embodiment 1, the floating matter discharge port 21 is penetrated and opened in the tangential direction with respect to the inner peripheral side wall surface 15a of the floating matter collection | recovery tank 15 seeing from the upper side. As a result, the fluid to be processed that flows into the recovery tank 15 and swirls along the inner peripheral side wall surface 15a can be reliably discharged at high speed in the swivel tangential direction. Therefore, the discharge performance of the fluid to be processed in the recovery tank 15 can be sufficiently enhanced, and the fluid to be processed in the recovery tank 15 can be reliably prevented from becoming a fluid resistance.

-Configuration of magnetic particle removal device-
As shown in FIG. 15, the magnetic particle removing device 50 is placed on the upper wall portion 104 a in the super clean tank 104. The ejector valve 106 that sucks the magnetic particles j removed from the fluid to be treated is sucked by supplying a part of the fluid to be treated supplied from the pump 105 to the cyclone separation / removal device 1 in a divided state. It is designed to generate power.

  As shown in FIG. 16, the casing 150 of the magnetic particle removing device 50 includes a side wall portion 151, a bottom wall portion 152, and an upper wall portion 153. A discharge cylinder portion 154 is erected on the bottom wall portion 152. A water level adjusting sleeve 155 is screwed into the upper portion of the discharge cylinder portion 154, and the water level of the fluid to be treated in the casing 150 can be adjusted by adjusting the screwing amount.

  A motor 56 that transmits a driving force to a drive shaft 61 that rotationally drives the disk-shaped suction portion 60 and a gear case 63 are fixed to the upper wall portion 153 of the casing 150 via a support plate 64.

  As shown in FIG. 17, the guide duct 67 for guiding the fluid to be processed discharged from the cyclone separation / removal device 1 through the cylindrical discharge pipe 6 to the suction surface 51a of the disk-like suction portion 60 has a tank width. An inner duct wall 67a and an outer duct wall 67b extending in the direction, and duct side walls 67g and 67h that connect both edge portions in the width direction of the inner and outer duct walls 67a and 67b, respectively.

  The outer duct wall 67b has a vertical wall portion 67c extending downward from the lower surface 64c of the support plate 64, and an inclined surface that is connected to the lower end of the vertical wall portion 67c and is inclined downward toward the other side in the tank length direction. It comprises a portion 67d and a horizontal projecting piece 67e that is connected to the lower end of the inclined portion 67d and projects to the other side in the tank length direction. The horizontal protruding piece 67e is arranged substantially in parallel along the suction surface 51a, and a slight gap is formed between the suction surface 51a and the lower surface of the horizontal protruding piece 67e so as not to rub against each other. Has been. An arc-shaped notch 67f having a radius slightly smaller than the radius of the disc-like suction portion 60 is formed at the other side edge in the tank length direction of the horizontal protruding piece 67e. In other words, the disc-shaped suction portion 60 is configured such that only the peripheral edge is covered by the horizontal protruding piece 67e.

  The inner duct wall 67a extends downward from the lower surface 64c of the support plate 64, and is formed so that its lower end edge is located above the lower end of the vertical wall portion 67c in the outer duct wall 67b. The lower edge of the inner duct wall 67 a constitutes the upper side of the opening 68 in the guide duct 67. As will be described later, a part of the opening 68 is covered by the opposing magnetic plate bracket 69 ′ and the opposing magnetic plate 161, and becomes a flow path 70 of the fluid to be processed supplied through the guide duct 67. , Between the lower surface of the opposing magnetic plate 161 and the upper surface of the disk-shaped adsorption portion 60.

  Further, side plates 67i and 67j extending to the vicinity of the drive shaft 61 of the disk-like suction portion 60 are provided on the duct side walls 67g and 67h connecting the inner and outer duct walls 67a and 67b on the outer side in the tank width direction. The fluid to be treated is made difficult to escape to the tank width direction side of the disc-like adsorption portion 60.

  On the inner duct wall 67a of the guide duct 67, the vertical portion 69d of the opposing magnetic plate bracket 69 'composed of the vertical portion 69d and the horizontal portion 69a is attached by screwing or bolt fastening. A counter magnetic plate 161 is attached to the horizontal portion 69a of the counter magnetic plate bracket 69 'by screwing or bolt fastening. As a result, the counter magnetic plate 161 and the suction surface 51a of the disk-like suction part 60 are arranged so as to face each other with a predetermined gap therebetween, and the flow path 70 of the fluid to be processed is formed therebetween. It has become.

  A bolt insertion hole for bolting the vertical portion 69d to the inner duct wall 67a is a long hole 69f extending in the vertical direction, whereby the mounting position of the opposing magnetic plate bracket 69 'in the vertical direction ( That is, by adjusting the height position of the opposing magnetic plate 161, it is possible to adjust the flow path cross-sectional area of the fluid to be processed that flows on the adsorption surface 51 a of the disc-like adsorption portion 60.

  Here, the horizontal portion 69a of the opposing magnetic plate bracket 69 'and the central portion in the tank width direction at the other side portion of the opposing magnetic plate 161 in the tank length direction are U-shaped to avoid interference with the drive shaft 61. Shaped notches 69b and 161a (see FIG. 17) are formed.

  As shown in FIG. 18, the removal main body 80 that scrapes the magnetic particles j adsorbed to the disc-like adsorbing portion 60 includes a plate-like scraping member 81, a plate-like magnetic shield member 86, and a housing member 83. And is configured.

  As shown in FIG. 17, the scraping member 81 is a schematic top view extending from the center side of the disk-shaped suction portion 60 toward the radially outer side (in this embodiment, from one side to the other side in the tank length direction). It has a rectangular shape and is provided so that its lower surface comes into contact with the suction surface 51a of the disk-like suction portion 60. The scraping member 81 is formed with a scraping surface 81a having an inclination that increases the distance from the suction surface 51a from the front side to the rear side in the relative movement direction. The material of the scraping member 81 is not particularly limited. For example, the scraping member 81 is made of an acrylic material so as to reduce sliding resistance with the stainless steel circular plate 51 (suction surface 51a).

  The magnetic shield member 86 is laminated on the upper surface of the scraping member 81 and has an inclined surface that is continuous with the scraping surface 81 a of the scraping member 81. Moreover, it has a shape that extends radially outward from the center of the apparatus so as to straddle the permanent magnet 55 on the outer peripheral side from the permanent magnet 55 on the outer peripheral side provided in the disc-like attracting portion 60. The magnetic shield member 86 is made of, for example, a magnetic material plated with nickel. The thus configured magnetic shield member 86 is attracted to the permanent magnet 55 of the disk-like suction portion 60, thereby bringing the scraping member 81 into close contact with the suction surface 51a of the disk-like suction portion 60. . Further, the attracting force of the permanent magnet 55 with respect to the magnetic particles j scraped off by the 81 and reaching the upper side of the magnetic shield member 86 is reduced, so that the particles can be easily discharged from the particle discharge port 83g.

  The housing member 83 is made of, for example, aluminum which is a nonmagnetic material, and is provided so as to cover the scraping member 81 and the magnetic shield member 86, and a recovery space 82 is formed therebetween. As shown in FIG. 17, the collection space 82 has a particle suction port 83c that opens to the front side in the relative movement direction, and has a substantially right angled isosceles triangle that narrows toward the rear side in the relative movement direction. It has a shape. A particle discharge port 83g that opens above the removal main body 80 is formed at a substantially vertex portion on the rotation direction side. That is, the magnetic particles j scraped off from the suction surface 51a of the disk-like suction portion 60 by the scraping member 81 are gradually gathered in the vicinity of the particle discharge port 83g and upward from the particle discharge port 83g as will be described later. It comes to be sucked.

  Further, a drain hole 88 is formed in the upper wall of the housing member 83. By providing such a drain hole 88, a flow of the fluid to be treated that flows in from the particle suction port 83c and escapes from the drain hole 88 is generated, and the fluidity of the magnetic particles j is increased, thereby efficiently collecting the space. It becomes easy to introduce into 82. Depending on conditions such as the flow rate of the fluid to be treated and the amount and size of the magnetic particles j, the drain hole 88 is not necessarily provided. The same applies to the case where a configuration such as a modified example described later is used.

  A magnetic particle discharge pipe 87 is connected to the particle discharge port 83g via a pipe joint 85, and the magnetic particle discharge pipe 87 is connected to a cyclone supply storage tank 109. An ejector valve 106 is provided in the middle of the magnetic particle discharge pipe 87, and a process of supplying the fluid supply port 106 a of the ejector valve 106 from the pump 105 (see FIG. 15) to the cyclone separation / removal device 1. By branching and supplying a part of the fluid, the magnetic particles j scraped into the recovery space 82 are sucked from the particle discharge port 83g.

-Operation of magnetic particle removal device-
In the to-be-processed fluid purification system 100 provided with the magnetic particle removal apparatus 50 comprised as mentioned above, the lightweight (1 micrometer-5 micrometers) discharged | emitted from the cyclone type | mold separation / removal apparatus 1 and guide | induced to the magnetic particle removal apparatus 50. ) The fluid to be treated containing the magnetic particles j flows into the magnetic particle removing device 50 from the inlet 64a of the magnetic particle removing device 50. That is, the fluid to be treated that has flowed from the introduction port 64a flows downward through the guide duct 67, and at the lower end thereof, the suction surface 51a of the disc-shaped suction portion 60, the counter magnetic plate 161, and the like. And flows from one side of the tank length direction to the other side (see FIGS. 16 and 17). Thus, while the fluid to be treated flows through the flow path 70, the magnetic particles j contained in the fluid to be treated receive the magnetic attraction force from the permanent magnet 55 and are attracted to the attracting surface 51a. It will be.

  Here, since the opposing magnetic plate 161 is provided so as to face the permanent magnet 55 of the disc-like adsorption portion 60 as described above, the permanent magnet 55 is simply provided on the magnetic particles j in the fluid to be treated. Large magnetic attraction force works compared to the case where it is. Therefore, the magnetic particles j are efficiently adsorbed on the adsorption surface 51a.

  The magnetic particles j adsorbed on the adsorption surface 51a are scraped and removed by the removal main body 80. That is, the disk-like suction portion 60 is rotated around the drive shaft 61 by the motor 56 in the counterclockwise direction as viewed from above the apparatus, so that the removal main body portion 80 is rotated clockwise with respect to the suction surface 51a. Move relative. As a result, the magnetic particles j (see FIG. 18) are scraped off by the scraping surface 81a formed on the scraping member 81 of the removal main body 80. The scraped magnetic particles j are sucked into the recovery space 82 from the particle suction port 83c by the suction action of the ejector valve 106, and the sucked magnetic particles j together with the surrounding fluid to be treated are discharged into the particle discharge port. It is led from 83 g into the magnetic particle discharge pipe 87 and discharged to the cyclone supply storage tank 109 on the downstream side. In this way, the clean fluid to be treated from which the magnetic particles j have been removed is accumulated in the casing 150, and when it exceeds a predetermined water level, it is discharged from the water level adjusting sleeve 155 (see FIG. 16) into the super clean tank 104, Supplied to the machine tool 101.

  As described above, in the above-described embodiment, since the opposing magnetic plate 161 is provided to face the permanent magnet 55 of the disk-shaped adsorption portion 60, the permanent magnet 55 is simply attached to the magnetic particles j in the fluid to be treated. Compared with the case where it is provided, a large magnetic attraction force works. Therefore, the magnetic particles j are efficiently adsorbed on the adsorption surface 51a. In addition, at the portion where the opposing magnetic plate 161 is not provided, the attracting force is small, so that the attracted magnetic particles j can be efficiently scraped.

  In the above embodiment, the drain hole 88 is formed in the housing member 83. By doing so, the fluid to be processed flowing from the one side to the other side in the tank longitudinal direction in the flow path 70 circulates from the particle suction port 83c to the water draining hole 88, thereby the recovery space. The fluidity of the fluid to be treated (magnetic particles j) in 82 can be enhanced. Therefore, the recovery efficiency of the magnetic particles j into the recovery space 82 can be further improved.

  In the above example, the removal main body 80 is formed with the recovery space 82 having a substantially right isosceles triangle shape. However, the present invention is not limited thereto, and the apex angle may be increased or decreased. May be. Further, the particle discharge port 83g may be formed in a shape close to the outer peripheral side according to the difference in the amount of the magnetic particles j depending on the radial position of the disc-like adsorption portion 60.

  In addition, the direction of the magnetic particles j introduced into the magnetic particle discharge pipe 87 from the particle discharge port 83g is the same as the flow direction of the fluid to be processed on the disk-like adsorption portion 60. The shape and the arrangement direction of the removal main body 80 may be set so that the magnetic particles j are more easily discharged by the natural flow of the fluid to be processed.

(Embodiment 3)
The suction direction of the magnetic particles j scraped off by the scraping member 81 can be set in various ways according to the layout of the constituent elements, for example, the horizontal direction as in the first embodiment, but different from the first embodiment. It is also possible to suck in. Specifically, for example, as shown in FIGS. 19 to 21, a magnetic particle discharge pipe 87 is provided at a particle discharge port 83 g communicating with the recovery space 82. It is connected horizontally from the rear side in the moving direction. Therefore, the magnetic particles j scraped off from the suction surface 51a of the disc-like suction part 60 by the scraping member 81 and collected in the vicinity of the particle discharge port 83g from the particle suction port 83c are attracted by the suction force of the ejector valve 106. It is sucked in horizontally from the discharge port 83g. Thereby, the attracted magnetic particles j can be more easily discharged to the cyclone supply storage tank 109 via the magnetic particle discharge pipe 87.

(Embodiment 4)
As means for actively collecting the magnetic particles j scraped off by the scraping member 81, instead of being sucked by the ejector valve 106, for example, as shown in FIGS. The fluid to be treated may cause a flow that flows into the recovery space 82 from the particle suction port 83c of the removal main body 80, and may be pushed away and discharged to the cyclone supply storage tank 109. More specifically, a nozzle head 89a is provided in the vicinity of the particle suction port 83c. From the nozzle 89b formed in the nozzle head 89a, the fluid to be processed is ejected toward the inside of the recovery space 82. The magnetic particles j in the vicinity of the particle suction port 83c scraped off from the adsorption surface 51a of the circular plate 51 by the scraping member 81 are ejected by the flow of the ejected fluid to be treated or pushed away. It flows into the pipe 87 and is discharged to the cyclone supply storage tank 109 by dropping due to its momentum and / or its own weight.

  In addition, as a fluid supplied to the fluid supply pipe 89, by diverting a part of the fluid to be processed supplied from the pump 105 to the cyclone separation and removal apparatus 1 to the fluid supply pipe 89 as described above, Although manufacturing costs can be easily reduced, the present invention is not limited to this, and a separate pump may be provided to supply a clean fluid to be processed from the super clean tank 104. In this case, even if the fluid to be treated ejected from the nozzle 89b leaks without returning to the recovery space 82 from the particle suction port 83c and returns to the super clean tank 104, the magnetic particles in the super clean tank 104 are thereby generated. It is easy to prevent an increase in j.

  In addition, the magnetic particles j may be collected more reliably by using a combination of the configuration in which the magnetic particles j are pushed as described above and the configuration in which the magnetic particles j are attracted as in the first embodiment.

(Embodiment 5)
FIG. 25 shows the arrangement of the magnetic particle removing device 50 according to the fifth embodiment of the present invention and the configuration of the drum-like adsorbing portion 411 different from those of the first embodiment.

An inlet 64a is formed in the upper wall portion 110a of the processing tank 110 and is discharged from the cyclone processing container 2. The treated fluid flows into the treatment tank 110 from the introduction port 64a.

  The fluid to be treated which has flowed into the treatment tank 110 from the introduction port 64a is guided by the guide casing 74 and flows in the counterclockwise direction around the shaft 61 along the adsorption surface 51a of the drum-like adsorption portion 411. 111 is discharged.

  The guide casing 74 can be adjusted in its radial position so that the cross-sectional area of the flow path 70 between the suction surface 51a and the guide casing 74 is variable. By this adjustment, for example, fine sludge (magnetic particles j) of 1 μm to 5 μm can be reliably removed.

  The drum-like adsorbing portion 411 includes a cylindrical main body 112 made of a cylindrical nonmagnetic material, and permanent magnets (not shown) arranged on the inner peripheral side surface 112a of the cylindrical main body 112 at a predetermined interval in the circumferential direction.

The cylindrical main body 112 is fixed to a drive shaft 61 penetrating through the axial center of the cylinder main body 112, and the drive shaft 61 is connected to an output shaft of a motor (not shown) so as to be able to transmit power. The yoke may be other as long as the magnetic force of the permanent magnet on one side can be increased. The yoke is not limited to this embodiment, and may be a nickel-plated magnetic body, a simple magnetic body, or the like.

  A removal main body 80 is disposed on the suction surface 51 a at the upper end of the drum-like suction part 411. Since the basic configuration of the removal main body 80 is the same as that of the first embodiment, the description thereof is omitted here.

  The removal main body 80 is relatively moved in the clockwise direction along the suction surface 51a when the cylindrical main body 112 (drum-like suction portion 411) is rotated counterclockwise around the shaft 61 by the motor 56. . The removal main body 80 scrapes the magnetic particles j on the suction surface 51a with the scraping surface 81a while moving relative to the suction surface 51a in the clockwise direction. The material is sucked into the member 83 (within the collection space 82) and removed. Thus, as in the first embodiment, the magnetic particles j adsorbed on the adsorption surface 51a can be sucked and removed before being re-adsorbed on the adsorption surface 51a. An effect can be obtained.

  Further, in this embodiment, the rotation direction of the drum-shaped adsorbing portion 411 and the rotational flow direction of the fluid to be processed are coincident with each other in the counterclockwise direction around the shaft 61. The magnetic particles j can be efficiently removed.

  In particular, in this embodiment, since the permanent magnet can be arranged inside the cylindrical attracting surface 51a, the installation range of the permanent magnet is wide and the attracted surface is wide, so that it is effective in increasing the attracting rate with a compact shape. Is.

(Embodiment 6)
FIG. 26 is a combination of the drum-like suction portion 411 similar to that of the fifth embodiment and the removal main body portion 80 as described in the second embodiment. Although not an essential component, in this embodiment, a counter magnetic plate 461 is provided on the outer peripheral side of the guide casing 74 so as to face the permanent magnet provided on the inner peripheral side surface 112a of the cylindrical body 112. Similar to 5, the magnetic attractive force is increased. Similarly, the removal main body 80 as described in the second to fourth embodiments may be combined.

  Even in this configuration, similarly to the fifth embodiment, the magnetic particles j adsorbed on the adsorption surface 51a can be removed by suction before being adsorbed again on the adsorption surface 51a. The effect of this can be obtained.

(Other embodiments)
The arrangement of the permanent magnets 55 in the disc-like attracting part 60 is not limited to that shown in FIG. 11, but may be arranged as shown in FIG. 27, for example. Various arrangements of the polarity of the permanent magnet 55 may be set. Specifically, for example, when three rows are provided in the radial direction as shown in FIG. 27, the polarity on the surface side may be set to NSN, SNN, SSN, or the like from the inner peripheral side. Also, the polarity may be varied in the circumferential direction.

  The yoke 54 is not limited to be provided in correspondence with each permanent magnet 55, but may be provided so that a plurality of permanent magnets 55, particularly those having different polarities on the surface side, are magnetically coupled. . More specifically, for example, when the permanent magnet 55 is arranged as shown in FIG. 11, an arc-shaped or donut-shaped yoke 54 having a width extending between the inner peripheral permanent magnet 55 and the outer peripheral permanent magnet 55 is provided. Etc.

Efficient magnetic particles, magnetic particles that are easily trapped by centrifugal force even if they are difficult to settle quickly due to their own weight, and fine magnetic particles that can be efficiently removed or attracted easily by magnetic attraction. Although it can be removed well, it is not necessarily limited to the combination and arrangement order of these components, and various settings can be made according to the properties of the fluid to be processed and the required processing capacity.

  Specifically, for example, as shown in FIG. 28, the magnetic particle removal device may be omitted, and the dust separation tank 103 and the cyclone separation / removal device 1 may be combined. In this case, as shown in the drawing, partition walls 104e and 104f may be provided so as to easily obtain a removal effect due to dust precipitation in the superclean tank 104. Further, the magnetic particle removing device 50 and the partition walls 104e and 104f may be used in combination.

  In these cases, when the magnetic particle removing device 50 is not removed or the magnetic particle removing device 50 is not provided, the dust that has settled in the super clean tank 104 is provided at the bottom of the super clean tank 104, for example. Further, the dirty tank 102 can be discharged through the discharge pipe 104c and the discharge valve 104d. Conversely, the dust that is light and floats on the surface in the super clean tank 104 is supplied to the cyclone from the return pipe 104b when the water level of the fluid to be treated stored in the super clean tank 104 reaches a predetermined water level h2, for example. It can be made to return to the storage tank 109 for use. Such a configuration of the return pipe 104b, the discharge pipe 104c, and the like can prevent dust in the super clean tank 104 from accumulating to a predetermined amount or more, and clean fluid from the super clean tank 104 can be produced. It can be supplied to the machine 101 and used as a coolant.

  Further, the fluid to be treated is not necessarily supplied to the cyclone separation / removal device 1 after removing relatively large dust in the dust separation tank 103, but as shown in FIG. May be supplied to the cyclone separation / removal apparatus 1 and the separated dust may be sent to the dust separation tank 103 and discharged. That is, even in such a case, an efficient removal effect of magnetic particles and the like can be obtained by combining the cyclone separation / removal device 1 and the magnetic particle removal device 50.

  In each of the above embodiments, before the magnetic particle j in the fluid to be processed is separated and removed by the magnetic particle removing device 50, the separation and removal processing of the magnetic particles j is performed in advance by the cyclone separation and removal device 1. However, it is not necessarily limited to this. For example, depending on the properties, flow rate, content, etc. of the fluid to be treated, the separation / removal processing is performed by the cyclone separation / removal device 1 after the separation / removal processing is performed by the magnetic particle removal device 50. Alternatively, the cyclone separation / removal device 1 may not be provided, and the removal may be performed only by 50. That is, the selective combination of the cyclone type separation / removal device 1, the magnetic particle removal device 50, and the dust separation device 108 and the processing order can be variously set according to the properties of the fluid to be treated and the dust.

  In addition, as the cyclone type separation / removal device, various configurations can be applied. For example, a cyclonic separation / removal apparatus 1 as shown in FIG. 30 may be used. In the cyclone type separation / removal apparatus 1, the inner peripheral side wall surface 2g of the cyclone type processing vessel 2 is formed at the upper end portion thereof, and the cylindrical portion 2f whose inner diameter is substantially constant over the entire vertical direction, and the cylinder An upper inverted conical portion 2b that is continuously provided on the lower side of the shape-like portion 2f and has an inner diameter that decreases generally downward, a conical portion 2c that is successively connected to the lower portion, and a two-stage lower inverted conical portion 2d. Is formed. The upper inverted conical portion 2b has a large apex angle in the vicinity of the upper portion, and a portion having a small apex angle and a cylindrical portion below the apex angle. The conical portion 2c increases in diameter toward the lower side, and connects the cylindrical portion and the lower inverted cone-shaped portion 2d below the cylindrical portion. Here, in the example shown in the figure, the fluid vortex portion 2e is divided into three side wall portions 2i. However, the present invention is not limited to this, and may be integrated or divided into two. The lower inverted conical portion 2d may be provided only in one stage.

  The partition plate 18 that divides the levitated substance collection tank 15 and the cylindrical portion 2f is composed of a partition portion 18a and a boss portion 18b, and is attached by fitting the boss portion 18b into the cylindrical discharge pipe 6. Yes.

  A sleeve 6 c is fitted into the lower part of the cylindrical discharge pipe 6. A spiral projection 6a is formed on the outer periphery of the sleeve 6c in a direction corresponding to the swirling and descending flow of the fluid to be processed. More specifically, for example, the spiral protrusion 6a is formed in two strips with a rectangular cross-sectional shape and a lead angle of 30 °. Here, the direction of the spiral protrusion 6a (right screw direction or left screw direction) may be determined according to, for example, the direction of the swirl flow. In the above example, the inner diameter of the cylindrical discharge pipe 6 and the outer shape of the portion other than the spiral projection 6a in the sleeve 6c are constant, but the outer peripheral surface or the inner side of the lower end portion of the cylindrical discharge pipe 6 is shown. The peripheral surface may be slightly expanded outward so that centrifugal force acts on the fluid more reliably. In addition, the length and position of the permanent magnet 10 provided in the upper circumferential groove 11 in the vertical direction are set in a range where, for example, the spiral protrusions 6a having one pitch or more are formed.

  In addition, you may form not only the above spiral protrusions 6a but a spiral groove. Further, instead of or together with such a spiral groove or spiral groove, a spiral groove or a spiral projection may be provided on the inner periphery of the upper inverted conical portion 2b.

  By providing the spiral grooves and spiral protrusions as described above, the swirl speed of the fluid to be processed is increased, and minute magnetic particles are captured by the spiral grooves and spiral protrusions, so that the removal efficiency from the fluid to be processed is increased. Can be greatly improved. That is, when the direction of the spiral groove 2j coincides with the direction of the swirling and descending flow of the fluid to be treated, the flow of the fluid to be treated becomes smooth and the magnetic particles j are stably stabilized on the inner peripheral side wall surface 2g and the spiral. The action pressed against the bottom of the groove 2j is increased. On the other hand, when the direction of the spiral groove 2j is different from the direction of the swirling downward flow of the fluid to be processed, the fluid to be processed crosses the spiral groove 2j, so that the magnetic particles j are easily caught by the spiral groove 2j. The action becomes larger. Further, a larger centrifugal force can be applied by setting the lead angle of the spiral groove 2j to be smaller than the direction of the swirling downward flow of the fluid to be processed to increase the rotational speed. Therefore, the lead angle, the number of strips, the cross-sectional shape, etc. of the spiral groove 2j may be set according to the flow velocity and viscosity of the fluid to be treated, the size, shape, specific gravity and the like of the magnetic particles j.

  Further, the magnetic particles j are not limited to be adsorbed to the disc-shaped adsorbing portion 60 as described above, but may be adsorbed to the drum-shaped adsorbing portion 411 as shown in FIGS. 31 and 32, for example.

  The housing 400 of the magnetic particle removing apparatus 50 is configured by fastening a side wall housings 402 and 403 and a bearing cover 404 to a cylindrical housing 401 with bolts 406.

  In the housing 400, a drum-shaped adsorption portion 411 is provided. The drum-like adsorbing portion 411 is configured by attaching a drum 412 to a rotating shaft 414 via a side wall 413. A permanent magnet 55 and a yoke 54 are embedded in the outer peripheral surface of the drum 412. The arrangement of the permanent magnets 55 can be variously set. For example, the drum 412 has an N-pole permanent magnet 55 and an S-pole permanent magnet 55 arranged in the longitudinal direction of the rotating shaft 414. . In addition, you may make it arrange | position more permanent magnets 55 not only in 2 rows. Further, the yoke 54 may be provided on the inner peripheral side over the permanent magnets 55 arranged in the longitudinal direction of the rotating shaft 414 as described above so that these permanent magnets 55 are magnetically coupled. Alternatively, the drum 412 itself may be formed of a magnetic material and act as a yoke. In this case, in order to attach the permanent magnet 55 to the drum 412, for example, a gap of about 1 mm to 3 mm is formed with respect to the outer shape of the permanent magnet 55 at a depth of about 2/3 of the thickness of the permanent magnet 55. In the shallow recess, a stepped recess having a depth approximately one third of the thickness of the permanent magnet 55 and a shape substantially equal to the outer shape of the permanent magnet 55 is provided, and the deep recess is permanently provided. The magnet 55 may be fitted. Accordingly, it is possible to ensure the positioning of the permanent magnet 55 and to prevent the leakage of the magnetic field lines and to reliably obtain the action of the drum 412 as a yoke. Further, the permanent magnet 55 is not limited to be exposed on the surface of the drum 412, and the drum-shaped attracting portion 411 may be covered with a stainless steel cylinder.

  The rotating shaft 414 of the drum-shaped adsorption unit 411 is rotatably supported by a bearing 421, and the driving force of the motor 431 is transmitted through the gear 433 in the speed reducer 432, and rotates in the clockwise direction in FIG. It is supposed to be. A seal 422 is provided inside the housing of the bearing 421 so that the fluid to be treated does not flow into the bearing 421.

  The cylindrical portion housing 401 is provided with an inlet port 401a for a fluid to be processed, while the side wall portion housing 403 is provided with a discharge port 403a. The fluid to be treated that has flowed from the inlet 401a flows between the cylindrical housing 401 and the drum 412 and flows in the counterclockwise direction in FIG. 31 opposite to the rotation direction of the drum-shaped adsorption portion 411. It is discharged from the outlet 403a.

  Here, when the rotation direction of the drum-shaped adsorption part 411 and the flow direction of the fluid to be treated are opposite to each other as described above, the magnetic particles j adsorbed on the drum 412 collide with the fluid to be treated flowing from the inlet 401a. Then there is a high possibility of withdrawal. Therefore, in the present embodiment, a guide plate 405 is provided on the drum 412 side of the introduction port 401a so that the fluid to be processed that has flowed from the introduction port 401a does not directly hit the surface of the drum 412.

  A partially cylindrical counter magnetic plate 461 is provided between the cylindrical housing 401 serving as the flow path of the fluid to be processed and the drum-shaped adsorption portion 411, and the attractive force of the magnetic particles j by the permanent magnet 55 is increased. It is like that.

  In addition, a flow rate regulating plate 463 that can rotate around the rotation shaft 464 is provided in the flow path of the fluid to be processed, and according to the amount, specific gravity, size, and the like of the magnetic particles j in the fluid to be processed, The flow rate of the fluid to be processed can be adjusted.

  In the vicinity of the upper portion of the drum 412, a scraping member 451 having a scraping surface 451a that comes into contact with the drum 412 (or is slightly spaced apart and close) is provided. That is, the magnetic particles j adsorbed on the drum 412 are scraped off by the scraping surface 451a, and are guided and discharged by the guide duct 451b.

  Even when the magnetic particles j are attracted to the drum-shaped attracting portion 411 as described above, the opposing magnetic plate 461 is provided so as to face the permanent magnet 55 embedded in the drum 412, so that a large magnetic attraction force acts. Thus, the magnetic particles j can be efficiently removed.

  Further, as still another example of the magnetic particle removing apparatus 50, it may be configured as shown in FIG. This magnetic particle removing device 50 is different from the above example (FIGS. 31 and 32) in that the fluid to be treated flows in the same direction as the rotation direction of the drum-shaped adsorption unit 411. That is, the side wall housing 402 is provided with an introduction port 403b in addition to the discharge port 403a. The fluid to be treated that has flowed in from the inlet 403b flows in the clockwise direction in FIG. 33, which is the same as the rotation direction of the drum-like adsorption portion 411, and the magnetic particles j are adsorbed in the drum-like manner until being discharged from the outlet 403a. Part 411 is attracted.

  Also in the magnetic particle removing apparatus 50 configured as described above, since the counter magnetic plate 461 is provided, the magnetic particles j can be efficiently removed by applying a large magnetic attractive force. In particular, by making the rotation direction of the drum-shaped adsorption part 411 and the flow direction of the fluid to be processed the same direction, the magnetic particles j once adsorbed on the drum-shaped adsorption part 411 are peeled off by the flow of the fluid to be processed. Since the possibility can be reduced, the removal efficiency of the magnetic particles j can be further improved easily.
