Description

  The present invention relates to a dust collector that can be cleaned safely and easily.

  It has been known that dust collectors capture dust by using a filter. For example, in a conventionally known dust collector (not shown), the main body of the dust collector is rectangular in order to place a filter, and a filter outlet is arranged in front of the dust collector so that the filter can be taken out from the outlet. In the dust collector of the said structure, the member for attaching a filter was provided in the said dust collector main body, and it was set as the structure which arrange | positions the said filter in a dust collector by setting it as the structure which supports a filter with the member.

  In the dust collector having the above-described configuration, the filter outlet arranged at the front of the dust collector main body is opened, the filter is removed from the dust collector, and then the inside of the dust collector is cleaned, but the filter is attached to the inside of the dust collector. Therefore, it is difficult to sufficiently clean the inside of the dust collector. Moreover, although there exist what wash | cleans by injecting water and a washing | cleaning liquid from the nozzle inside a dust collector apparatus like an automatic washing apparatus, washing | cleaning was not necessarily enough.

  That is, in the dust collector having the structure as described above, there are members that become projections inside the dust collector, such as a member for attaching a filter, inside the dust collector main body, and even if the dust collector main body is cleaned, these members are attached. Part dust may remain. Moreover, since the external appearance of the dust collector has a rectangular shape, it is difficult to sufficiently clean the corner portion inside the dust collector. In this case, particularly when the dust is corrosive or septic, the dust collector itself may give off a bad odor or may cause a failure. If the dust collector body is rectangular as described above, the dust collector body must be reinforced in order to have a structure having sufficient strength against the suction pressure to the dust collector. In particular, when the reinforcing material is disposed inside the dust collector main body, the number of members that become protrusions increases inside the dust collector main body, so-called dust accumulation occurs, making it difficult to perform appropriate cleaning.

  In order to solve this problem, the invention proposed in Japanese Patent Application Laid-Open No. 2003-159547 is designed to suck dust-containing air in the tangential direction of the circumferential surface of the cyclone main body, which is entirely made into a cylindrical cross section and provided with a filter inside. By providing a mouth and swirling the dust-containing air sucked from the suction port in the cyclone body, relatively large dust is separated and dropped to the bottom side in the cyclone body, and the air containing fine dust is A cyclone type dust collector configured to be discharged out of the cyclone main body after filtering with a filter, wherein the cyclone main body has a bottomed structure with a bottom plate, and at least a side surface of the cyclone main body The cyclone type dust collector is characterized in that a dust discharge opening is opened, and a dust recovery bucket is connected to the dust discharge opening. A. In the present invention, since the dust collector body has a cylindrical cross section, the dust collector body can be structured to have sufficient strength against suction pressure without reinforcing the dust collector body. Further, since the shape of the dust collector is generally cylindrical in cross section, there is no portion corresponding to the corner portion inside the dust collector, and so-called dust accumulation is difficult to occur. Furthermore, since the hopper part provided in the cyclone lower part is removed in the said invention, a dust collector main body can be made low by the part of this hopper. However, in the case of the above-mentioned invention, since a blower or the like is provided on the upper part of the dust collector main body, when removing the filter, it is necessary to remove the blower and remove the filter inserted therein. When removing the filter, it is necessary to lift the filter almost vertically above the dust collector. Under this situation, the operator removes the upper part of the dust collector and then inserts it inside. The filter must be taken out, but the worker must do the above work on a stepladder or the like at a high place. Here, in order to improve the dust collection performance of the filter, it is necessary to increase the volume of the filter, and most of the filters used in such a dust collector have a cylindrical shape, but the diameter of the cross-sectional cylindrical shape of the dust collector Due to the limitation of the dimension in the direction, the diameter of the cylindrical shape cannot be increased, and the volume is increased only by increasing the length of the filter. Therefore, a filter having a length approximately the same as the height of the dust collector main body is used, and in order to extract the filter from the dust collector main body having such a configuration, at least the length of the filter from the dust collector main body is used. The filter must be pulled up to the same height and extracted. In such a case, the worker must remove the upper part of the filter from the height on the stepladder as described above, and pull out the filter, but such work is only dangerous. In addition, since the dust collector has a certain height, the ceiling height in the place where the dust collector is installed is required to be higher than a certain level, and the installation location is limited. Further, when the filter is pulled up at such a high place, dust or the like adhering to the surface of the filter is scattered near the upper side of the dust collector, and the dust collector may be contaminated. Especially in the upper part of the dust collector, in order to operate continuously while ensuring the dust collection performance of the dust collector, air is blown to the inside of the filter above the filter having a hollow structure after a certain period of time. A device called a backwash device, which is a filter clogging prevention device that has the function of blowing off clogged dust, etc. may be attached, but if dust adheres to these devices called a backwash device, further cleaning work is required. There is. Moreover, since dust may be scattered in the place where the dust collector is installed and the place may be contaminated, it is necessary to clean them. In addition, usually, as described above, the upper part of the filter must be opened as described above, so that a specialist must perform the cleaning cost. Since it is difficult, the possibility that the sucked dust etc. will corrode increases.

JP 2003-159547 A

  The present invention has been made paying attention to the above-mentioned points, and the operator can clean the dust collector without going up to a high place, thereby ensuring the safety of the worker and pranking dust in the cleaning operation. It is an object of the present invention to provide a dust collector that does not scatter and to provide a dust collector that does not require a space above the dust collector in the cleaning operation. Another object of the present invention is not to increase the manufacturing cost by adopting a simple configuration as much as possible. It is another object of the present invention to provide a structure in which dust accumulation is difficult to occur without providing a member that becomes a protrusion in the dust collector body. Another object is to make it easy to remove the filter, and to make it easy for the user to remove the filter, not a specialist. Further, in order to continuously operate the dust collector configuration while ensuring the dust collection performance of the dust collector, air is blown to the inside of the filter at regular intervals in the direction opposite to the flow of the air flow during the operation of the dust collector. When a so-called backwashing device, which is a so-called filter clogging prevention device, is attached to the top of the filter, the backwashing device, which is a filter clogging prevention device, is installed when the filter is washed. It is an object of the present invention to prevent dust from adhering to the backwashing device, which is the filter clogging prevention device, without any curing.

  In order to solve the above problems, the present invention is a dust collector that sucks dust from the suction port of the dust collector main body and captures the dust with a dust collection filter disposed inside the dust collector main body, and is disposed inside the dust collector main body. In order to take out the dust collecting filter and clean the dust collector, the dust collector main body is supported so as to be tiltable with respect to the dust collector frame. Since the dust collector main body is configured to be tiltable with respect to the dust collector frame, the operator can clean the inside of the dust collector main body on the installation surface of the dust collector instead of at a high place such as a stepladder. Moreover, the space above the dust collector is not necessary.

  In order to solve the above-mentioned problems, the present invention provides a means in which a shaft is provided in a dust collector main body and rotatably supported by a bearing member provided in the dust collector frame, and the dust collector main body is tiltably supported with respect to the dust collector frame. It is a thing. The dust collector body can be inclined with respect to the dust collector frame, and the number of parts required for the configuration can be suppressed as much as possible.

  In order to solve the above-described problems, the present invention is configured to tilt the dust collector main body that is tiltably supported by the dust collector frame by a support arm member with a damper disposed between the dust collector main body and the dust collector frame. Measures have been taken to loosen and regulate. By disposing the support arm with the damper, the operation in the tilting operation becomes gentle, and at the same time, the dust collector body does not tilt more than a certain level.

  In order to solve the above-mentioned problems, the present invention is a filter disposed inside a dust collector body, wherein the filter is inserted into the filter mounting member from above the hole of the filter mounting member, and the filter holding member from above. The filter is configured by fixing the flange portion of the filter unit, and the filter is suspended inside the dust collector main body by fitting the dust collector main body and the filter. Since the filter is arranged in this way, a member for supporting the filter is not required inside the dust collector main body, and the projections can be eliminated.

  In order to solve the above-described problems, the present invention provides means for enabling a filter disposed inside the dust collector body to be extracted from the upper portion of the dust collector. Thus, since it was set as the structure which can draw out a filter from the upper part of a dust collector main body, it can be performed by the user himself / herself, not a specialist.

  In order to solve the above-described problems, the present invention provides means for providing a movable filter clogging prevention device at the upper part of the dust collector filter. Since it was such a structure, the dust adhering to a filter becomes difficult to adhere to a filter clogging prevention apparatus.

Since the present invention is configured and operates as described above, the dust can be mischievously scattered while ensuring the safety of the worker by performing the cleaning work without the worker going up to a high place. There is an effect that there is no. Moreover, the effect of not increasing the manufacturing cost can be achieved by adopting the simplest possible configuration. Moreover, the effect that the safety | security of the said operator can be ensured can be show | played. In addition, it is possible to produce an effect that dust accumulation cannot be performed without providing a member that becomes a protrusion in the dust collector body. Further, it is possible to easily remove the filter, and even if the operator is not a specialist, that is, the user can easily remove the filter. Further, in the configuration of the dust collector, in order to perform continuous operation while ensuring the dust collection performance of the dust collector, air is passed through the filter in a hollow structure in a direction opposite to the air flow when the dust collector operates at regular intervals. When a device called a backwashing device, which is a filter clogging prevention device, is attached to the top of the filter and has the function of spraying dust on the filter, the curing of the backwashing device is not necessary. Without doing so, it is possible to achieve the effect of preventing dust from adhering to the backwashing device.

The dust collector 10 includes a dust collector main body 20 and a frame portion 50 that supports the dust collector main body 20, and has a configuration in which a dust collection container 80 is installed at a lower portion of the dust collector main body 20. The dust collector main body 20 has a cylindrical main body upper part 21 and a cylindrical body part 22 connected to a lower part thereof, and a cone part 24 having a substantially conical shape and a cylindrical discharge port part in the lower part thereof. 25. In the case of the present embodiment, the suction port 23 is arranged so as to face the tangential direction of the barrel portion 22 having the cylindrical shape in order to increase the dust suction efficiency. Here, since the suction port 23 has a circular cross section for connecting to hoses, and the mounting portion 23a of the suction port 23 has a square cross section, the mixture with the sucked dust is reduced, Since the air-fuel mixture with the sucked dust is placed on the inner wall surface of the body portion 22, the air-fuel mixture with the dust taken in from the suction port 23 is not directly applied to the built-in filter 70, and the filter 70 is Protect. Further, support members 29 and 29 are joined to the body 22 on both sides of the body 22.

  Moreover, although the frame part 50 which supports the dust collector main body 20 and the backwashing apparatus 30 mentioned later can also be manufactured with metal or resin etc., in this Example, stainless steel is used. This is because it has durability and rust does not easily occur even when washed. Further, the dust collector main body 20 is smoothly joined at the joint portions of the main body upper portion 21, the body portion 22 and the cone portion 24. This is to prevent dust from accumulating. In the present embodiment, so-called ribs 22a are provided in the direction in which the radial direction of the body 22 is slightly increased in order to increase the strength of the body 22. Further, the internal surface of the dust collector main body 20 is substantially mirror-finished by buffing. This is because there is less risk of dust accumulation. Further, as already described, the support members 29 and 29 are disposed on the body portion 22 of the dust collector main body 20, and the shaft portions 26 and 26 are provided on the support members 29 and 29.

  In this embodiment, a filter clogging prevention device is installed on the upper portion of the dust collector main body 20. The filter clogging prevention device may be that when the dust collector 10 is operated for a certain period of time or longer, the sucked dust enters the filter part 71 of the filter 70 and the filter part 71 may be clogged. For that purpose, air is blown to the inside 71b of the filter part 71, and air is circulated through the filter part 71 from the inside 71b of the filter part 71 having a hollow structure to the outside as described later, so that the filter part 71 The dust adhering to the outside of 71 can be dropped from the filter unit 71. Here, in this embodiment, the backwash device 30 will be described as a filter clogging prevention device. However, the present invention is not limited to these.

  A backwash device 30 is disposed on the upper portion of the dust collector main body 20. The action is that air is introduced from the backwashing device suction port 31a through the pipe 32 and stored in the air tank 33, and the air stored in the air tanks 33 and 33 is passed through a plurality of backwashing solenoid valves 34. The filter part 71 having a hollow structure is blown to the inside 71b of the filter part 71 through the backwash pipes 35a, 35b, 35c, 35d, 35e, 35f, and air is circulated from the inside of the filter to the outside or by impact. The dust adhering to the outside is removed. The backwash solenoid valve 34 and the backwash pipes 35a, 35b, 35c, 35d, 35e, and 35f connected to the solenoid valve 34 can be appropriately arranged and quantity depending on the arrangement or quantity of the filter. It is not limited to what was shown in. Further, the backwash device 30 is not necessary when the dust collector 10 is not operated for a long period of time, and is not an essential component of the dust collector 10. The two inlets 31a and 31b are provided in the dust collector 10 as long as one suction port 31a is provided. However, in the place where the dust collector 10 is actually installed, the two places are provided. This is because it is assumed that only one of the suction ports 31 can be used. Therefore, the other suction ports 31b that are not used are blocked by the plug so that air does not flow in.

  In the so-called backwash device 30 described above, an appropriate amount of air is injected in a very short time at pulsed time intervals. Therefore, the dust adhering to the outside can be dropped by the impact of the air jetted in the form of pulses toward the inside 71b of the filter 71 having a hollow structure or by the passage of air from the inside 71b of the filter portion 71 to the outside. it can. In this embodiment, for example, the opening / closing interval and the opening / closing time of the solenoid valve 34 are controlled by an electrical signal from a control device (not shown). For example, the backwash pipes 35a, 35b, 35c, 35d from the solenoid valve 34 are controlled. , 35e, and 35f, the air is injected into the filter unit 71. The order is, for example, the order of backwash pipes 35a, 35b, 35c, 35d, 35e, and 35f. The injection interval, the injection order, or the injection time and the air volume of the air tanks 33 and 33 are appropriately selected depending on the degree of contamination of the filter 70 or the size of the filter 70.

  The backwashing device 30 configured as described above has a substantially rectangular shape, and the inside thereof has the configuration as described above, and is placed on the upper portion of the dust collector main body 20. The backwash device 30 has a substantially circular hole 37 at the lower portion thereof, and communicates with the upper portion of the dust collector main body 20. Accordingly, the air from the backwash pipes 35 a, 35 b, 35 c, 35 d, 35 e, and 35 f through the hole 37 is directed to the upper part of the filter 70 and toward the inside 71 b of the filter part 71 having a hollow structure in the filter 70. Inject. The upper part of the backwash device 30 is closed with a lid (not shown). In addition, when the backwashing apparatus 30 is not required, the upper member which has the external shape of the same shape as the backwashing apparatus 30 which exhibits a rectangular shape can also be arrange | positioned (not shown). In this embodiment, the outer portion of the backwash device 30 is also made of stainless steel. It is because it is hard to rust.

  The frame unit 50 includes front vertical frames 51, 51 and rear vertical frames 52, 52, and the front vertical frames 51, 51 are connected by a front upper horizontal writing unit 53 at the upper part of the frame unit 50. The frames 52, 52 are connected to the rear upper horizontal note portion 55. Here, the front vertical frames 51 and 51 are slightly longer than the rear vertical frames 52 and 52, and one end portions of the side upper horizontal side portions 54 and 54 are connected to the upper end portion of the rear vertical frame 52, so The other ends of the note portions 54 and 54 are connected to a lower portion 51 a of the upper end portion of the front vertical frames 51 and 51. Also, support arm suspension members 90 and 90 with dampers are joined to the vicinity of the center of the side upper horizontal writing parts 54 and 54. That is, as described above, the support arms 91 and 91 with dampers are connected to the support members 29 and 29 joined to both sides of the body 22 so as to be extendable and contractible.

  In this embodiment, the front vertical frames 51 and 51 and the back vertical frames 52 and 52 are so-called square members. Casters 99, 99, 99, 99 are arranged at the lower ends of the front vertical frames 51, 51 and the rear vertical frames 52, 52, respectively. Here, the caster means a wheel that freely turns around an axis having a predetermined angle with respect to the wheel axis, and is intended to facilitate the movement of the dust collector 10. The backwashing device 30 is disposed on the upper side of the dust collector main body 20 by being installed on the side surface upper side note portions 54 and 54 and the rear upper side note portion 55. In this case, the attachments 38, 38 can be arranged so as to be movable above the backwash device 30 by the biasing of the air springs 92, 92 around the shafts 39, 39.

  The back middle horizontal note 57 is connected to the back vertical frames 52, 52. Also, one end of each of the side central horizontal note portions 56, 56 is connected to the back vertical frame 52, 52, and the other end of each of the side central horizontal note portions 56, 56 is connected to the front vertical frame 51, 51. Yes. Here, the back center horizontal cross section 57 is disposed above the side center horizontal cross sections 56, 56. Therefore, as described later, the dust collector main body 20 can also be used as a restriction on the operation that tilts when the dust collector body 20 rotates.

  The back bottom horizontal note 59 is connected below the back vertical frames 52, 52. Further, the bottom side horizontal bars 58 and 58 are connected to the lower part of the rear vertical frames 52 and 52 and the lower part of the front vertical frames 51 and 51, respectively. The back middle horizontal note portion 57, the side middle horizontal note portions 56, 56, the back bottom horizontal note portion 59, and the side bottom horizontal note portions 58, 58 connected in this way are substantially parallel to the floor surface. Note that the cross-sectional shapes of the side bottom portion horizontal note portions 58 and 58 and the rear bottom portion horizontal note portion 59 are L-shaped. Further, since the frame portion 50 is configured such that the middle horizontal letter part and the bottom horizontal letter part are not arranged on the front portion, there is no problem in the tilting operation in which the dust collector main body 20 rotates. Further, the front vertical frames 51 and 51 and the rear vertical frames 52 and 52, the front upper horizontal writing portion 53, the side upper horizontal writing portions 54 and 54, and the rear upper horizontal writing portion 55, the rear middle horizontal writing portion 57, and the side middle horizontal writing portion. 56, 56, the surface of the side bottom horizontal cross sections 58, 58, and the back bottom horizontal cross section 59 are substantially mirror-finished by so-called buffing. This is because there is less risk of dust accumulation.

  In the side central horizontal cross sections 56, 56, bearing members 60, 60 are provided in the middle of the vicinity between the front vertical frames 51, 51 and the rear vertical frames 52, 52. The bearing members 60, 60 have bearing portions 60 a, 60 a, and the bearing portions 60 a, 60 a pivotally support the shaft portions 26, 26 provided on the support portions 29, 29 disposed on the dust collector body 20. ing. Accordingly, since the frame portion 50 is configured as described above, the center portion and the bottom portion of the horizontal portion are not arranged in the front portion of the frame portion 50 as described above. The dust collector main body 20 can be rotated in the front direction of the frame part 50 around the center so that the upper part of the dust collector main body 20 can be tilted. Here, the position of the back center horizontal cross section 57 connected to the back vertical frames 52, 52 is such that the side center horizontal cross sections 56, 56 connect the front vertical frames 51, 51 and the back vertical frames 52, 52, respectively. Therefore, when the dust collector main body 20 is tilted in the front direction of the frame portion 50, the support arms 91 and 91 with the damper should be broken, and the dust collector main body 20 rotates. Even so, the dust collector main body 20 and the back middle horizontal letter 57 are in contact with each other so that the dust collector main body 20 does not tilt any more. However, normally, the support arm portions 91 and 91 with dampers regulate the inclination due to the rotation of the dust collector body 20. In addition, in the dust collector frame 50, the side surface upper horizontal writing parts 54, 54 have a fastener 20a that is fixed to the backwash device 30.

  The filter 70 includes a filter portion 71 and a filter attachment member 72. Further, in the present embodiment, the filter portion 71 is configured such that four filter members 71a are connected as a set by a collar portion 71C and the four filter members 71a are integrated. The filter member 71a may have a substantially cylindrical shape that is long in the vertical direction and short in the horizontal direction. However, in order to increase the surface area of the filter member 71a and increase dust collection efficiency, the cross-sectional shape of the filter member 71a is changed to a star shape. It has a shape (see FIG. 5C). Moreover, the filter part 71 has the inside 71b which exhibits a hollow structure. Also, so-called filter media are made of plastics and can be washed with water or the like.

Further, in this embodiment, the filter member 71a is connected as one unit by the flange portion 71C as a set of four as described above, and the filter portion 71 is respectively connected to the plurality of holes 72a in the filter mounting member 72 from above. Insert it. The plurality of holes 72a in the filter attachment member 72 are slightly smaller than the flange portion 71C. Therefore, the flange portion 71C is hooked by the filter attachment member 72, and the first filter retainer 73 and the second filter retainers 74, 74. Then, it is pressed from above the flange 71C and fixed by a known method. As such, since the filter unit 71 is fixed to the filter mounting member 72, the filter 70 from the filter mounting member 72, a configuration in which the filter unit 71 is suspended (see FIG. 2). Accordingly, the filter 70 is fitted to the upper part of the dust collector body 20 and is suspended inside the dust collector body 20, and a member supporting the filter 70 is not required inside the dust collector body 20, so that it is difficult to collect dust. Become. The first filter holder 73 and the second filter holders 74 and 74 have a plurality of holes 73a and a plurality of holes 74a, respectively. 71b is connected. Therefore, air can be injected from the backwashing device 30 toward the inside 71b of the filter portion 71 having a hollow structure in the filter 70.

  Here, the filter attachment member 72 has an edge 75. The edge 75 has a substantially U-shaped cross section, and the main body upper portion 21 of the dust collector main body 20 is fitted inside the U-shape. The handle portions 76 and 76 are used when the filter 70 is taken out, and the guard portions 77 and 77 are for supporting the filter 70 after the filter 70 is taken out, and at the same time the filter portion 71 and the dust collector. It serves as a guard provided for preventing contact with the main body 20. Moreover, the guide receiving part 78 and the guide part 79 determine the position when the filter part 71 and the dust collector main body 20 are connected. That is, as described above, the backwashing device 30 is installed in the upper part of the dust collector main body 20 and air is blown into the dust collection filter 70 through the backwashing pipe 35 in the backwashing device 30 to form a hollow structure. This is to remove the dust adhering to the outside of the filter 70, but to prevent the positions of the backwash pipe 35 and the filter portion 71 from shifting.

  The dust collecting container 80 has a substantially cylindrical shape or a bucket shape with a small concavity, and both are open at the upper end. In addition, in the upper part of the opening, the dust container attaching member 81 is placed, and in the lower part of the dust collector main body 20, the lever part 82 is operated so as to be along the groove part 25a. The dust container attaching member 81 placed on the dust collector main body 20 can be joined.

  The dust collecting container 80 is formed by molding using a transparent plastic material. The material constituting the dust collecting container 80 is preferably a transparent material having chemical resistance or impact resistance. In order to satisfy these requirements, for example, a polyester-based polyester is particularly preferable.

  Moreover, in order to remove the static electricity brought to the dust collecting container 80 by the dust collected by the dust collector 10, a plurality of slow current members 83 arranged in a partially exposed manner on the inner surface of the dust collecting container 80 are combined. . The slow current member 82 is preferably a conductive metal wire, but stainless steel wires are particularly preferable. The metal wire is welded and formed into a basket shape or a cylindrical shape substantially the same as the shape of the dust collecting container 80, and the whole is configured as one conductor. The dust collecting container 80 having the slow current member 82 is formed by so-called insert molding in which the slow current member 82 is inserted and resin molding is performed in an injection molding machine for molding a transparent plastic material. The dust collecting container 80 can also be cleaned with a cleaning agent or water.

  In the dust collector 10 having the above-described configuration, dust is collected by connecting a hose from a discharge port 88 installed at the upper part of the dust collector 10 using an external suction device (not shown) and performing suction. Can do.

  Next, a procedure for inclining the dust collector body 20 and taking out the filter 70 in the dust collector 10 will be described. In addition, although a present Example demonstrates the case where the backwashing apparatus 30 is mounted in the upper part of the dust collector 10, when the backwashing apparatus 30 is not mounted, it connects with the discharge port 88. The procedure for inclining the dust collector main body 20 and taking out the filter 70 is the same except that the member is removed (not shown).

  The connection with the dust container 80 connected in the lower part of the dust collector main body 20 is disconnected. That is, the dust collecting container 80 is detached from the dust collector main body 20 by lowering the lever 82 along the groove 25a. Further, the shaft of the connecting member 38 connecting the backwashing device 30 and the frame portion 50 by removing the fasteners 20a, 20a, 20a, 20a located on the side surface of the backwashing device 30 and lifting the handle 36. It pivots upward about the part 39. Here, since the air spring 92 is a so-called air spring, the backwash device 30 is urged upward. Therefore, the backwashing device 30 can be moved upward even if the operator who is the user does not put much force. Moreover, depending on the movement of moving the backwashing device 30 upward, the hanging part 30a in the lower part of the backwashing device 30 also moves upward. Here, since the shaft portion 39 of the connecting member 38 is disposed at a position slightly away from the frame portion 50, the hanging portion 30a moves substantially upward (see FIG. 7). Therefore, when the backwashing device 30 moves upward, the backwashing device 30 fitted in the upper part of the dust collector main body 20 is detached from the filter unit 70 (see FIG. 7A). In addition, when the backwashing apparatus 30 is not mounted, the member connected with the discharge port 88 is removed (not shown).

  In the above state, the backwashing device unit 30 and the dust collecting container 80 are removed from the dust collector main body 20, and an operator who is a user can tilt the dust collector main body 20. Here, since the front vertical frames 51 and 51 are configured to be higher than the rear vertical frames 52 and 52, the dust collector body 20 can be tilted without interfering with the front upper horizontal writing part 53. That is, in that case, the dust collector body 20 can be tilted to the front side of the drawing (see FIG. 7A) by rotating the dust collector body 20 around the shaft portions 26, 26 supported by the bearing members 60, 60. In that case, since the support arms 91 and 91 with a damper are attached between the flame | frame part 50 and the dust collector main body 20, the operation | movement which tilts the dust collector main body 20 becomes slow. Therefore, the tilting operation of the dust collector main body 20 tilts slowly, and it can be said that even a general user has high safety.

  When the tilting operation of the dust collector main body 20 is continued in the X to Y direction in FIG. 7, the extension of the support arms 91 and 91 with dampers is maximized and the tilt operation of the dust collector main body 20 is further prevented from rotating and tilting. . Moreover, since the filter 70 is only fitted to the upper part of the dust collector main body 20, the operator who is a user has the handle parts 76 and 76 in the upper part of the filter 70, and can pull out the said filter (FIG. 7D). reference). As already described, since the filter 70 is suspended from the top of the dust collector main body 20, there is no member that supports the filter 70 inside the dust collector main body 20, and it is difficult for dust to accumulate and the cleaning work is easily performed. be able to. In addition, when the filter 70 is removed, in order to prevent the weight balance of the dust collector main body 20 from being lost and the dust collector main body 20 from rotating, a fastener can be arranged (not shown).

  The filter 70 pulled out from the dust collector main body 20 as described above can be washed with water, and dirt such as dust can be removed. Further, since the dust collector main body 20 and the dust collector frame 50 are also made of stainless steel, they can be washed with water or a cleaning agent, and cleanliness can be maintained. At this time, since the backwashing device 30 moves upward, the dust adhering to the filter 70 hardly scatters upward, and the backwashing device 30 need not be cured. When the dust collector 10 and the like have been cleaned, the dust collector 10 can be returned to its original position by assembling in the reverse procedure.
