Description

  The present invention relates to a mist removing apparatus and a mist removing method, for example, a mist removing apparatus and a mist removing method suitable for removing oil mist emitted from a machine tool and discharging clean air.

For example, as shown in FIGS. 13 and 14, the cutting machine 103 is provided with a headstock 105, a tailstock 106, and a cutting tool 107 that hold a workpiece 104 made of metal such as steel, and cutting. Sometimes an oil supply device 108 and a cleaning device 109 are provided for supplying an oil-based cutting agent (hereinafter referred to as oil) mainly composed of mineral oil.
The oil supply device 108 includes an oil tank 110, an oil pump 111 that supplies oil to a cutting position, an oil ejection pipe 112, and the like. The oil supplied to the workpiece from the oil jet pipe 112 becomes mist, and is mixed with water vapor in the air to become a gaseous medium (hereinafter referred to as air). If this air is discharged into the building 101 as it is, the inside of the building 101 is contaminated, so that the air is discharged outside through the cleaning device 109. The cleaning device 109 has filter parts 113a and 113b using a porous nickel metal filter disposed on the air flow path, and air containing oil mist or the like is removed by the filter parts 113a and 113b. The oil mist captured by the filter portions 113a and 113b aggregates and falls as an oil component and is stored in the oil storage portion 114. As shown in FIG. 12, the cleaning device 109 is disposed for each machine tool 102, and the ducts 115 are connected to each other, and the duct 115 is connected to the electric dust collector 117 side via the focusing duct 116. All the air generated from each machine tool 102 side and from which oil mist and the like have been removed by the cleaning device 109 is introduced into the electrostatic precipitator 117, and mainly fumes that could not be removed by the cleaning device 109 are removed and cleaned. Air is exhausted.

However, the cleaning device 109 is installed for each machine tool 102 at a place where the machine tool 102 is installed, and further, ducts 115 are connected to each other so that fumes and the like are removed by the electric dust collector 117 and discharged to the outdoors. Because it is configured, when the operation of the electric dust collector 117 is started, air is also sucked from the cleaning device 109 corresponding to the machine tool 102 that is not in use, so that useless power is consumed and is unnecessary for maintenance. There was a problem that it was expensive. Furthermore, since the scale becomes large, there is a problem that the cost increases at the time of introduction.
Further, for example, when rearrangement of the machine tool 102 or introduction of another type of machine tool 102 is performed, it may be necessary to re-install the duct 115 or change the capacity of the electric dust collector 117 motor. There was a problem that it was not flexible at the time of renovation.
For this reason, a technology has been proposed in which an oil mist removing device that sucks in air containing oil mist, removes oil mist through a filter, etc., and discharges clean air is installed near the machine tool, for example. (For example, refer to Patent Document 1).

FIG. 4 is a perspective view showing a configuration of a blower of the oil mist removing device, FIG. 5 is a perspective view showing a configuration of a guide portion provided around the blower, FIG. 6 is an explanatory diagram for explaining the operation of the oil mist removing device, and FIG. 7 is an explanatory diagram for explaining the function of the mist trapping chamber constituting the oil mist removing device.

  The oil mist removing device in this example is arranged in the vicinity of a machine tool such as a cutting machine or a welding machine arranged in a building such as a factory, for example, by a ceiling suspension method, and removes oil mist generated by the machine tool. Used to exhaust clean air. Here, for example, a duct in which a hood arranged near the contamination source is attached to the tip is connected to the intake port of the oil mist removing device, and the oil mist is removed.

  As shown in FIGS. 1 to 5, the oil mist removing device 1 pressurizes the air sucked from the cylindrical intake section 2 and jets the oil mist from the air flowing from the blower 3. After being captured and removed, the mist capturing chamber 5 for exhausting the cleaned air and the device box (casing) 6 for housing the blower 3 are disposed so as to surround the side edge of the blower 3. Is provided with a guide unit 7 for blowing the air discharged in the centrifugal direction from the air and guiding the air to the mist capturing chamber 5, and a control unit 8 for supplying electric power to the blower 3, for example. ing.

  As shown in FIG. 4, the blower 3 is a centrifugal turbo blower having an impeller 11 in which a plurality of blades 11 a, 11 a,... Are arranged radially and a motor 12 that drives the impeller 11. The shafts of the impeller 11 and the motor 12 are attached to the device box 6 in a manner that is substantially in common with the central axis of the intake section 2. The blower 3 is configured to suck and pressurize air from the outside, and pressurize and aggregate mist contained in the sucked air.

  The mist capturing chamber 5 is formed in the lower part of the device box 6 and is attached in a suspended state to a cylindrical connecting portion 18 for guiding the air discharged from the blower 3 to the mist capturing chamber 5, and directed downward vertically. It is provided with a long bag-like nonwoven fabric 21 that is flexible and has a predetermined length (for example, 1 m) using, for example, a synthetic resin. That is, the mist capturing chamber 5 is arranged at a position where an air inlet into which air flows at a high speed, a position where air flowing in from the inlet collides, and a mist receiver 16 for adhering and capturing the indirectly mist, A bag-like non-woven fabric (filter member) 21 surrounds a predetermined space between the inflow port and the mist receiver 16 and attaches and captures the mist contained in the exhausted air.

In this example, the lower end portion of the bag-like non-woven fabric 21 is closed to be a bottom portion 21b. Therefore, the air flowing into the mist capturing chamber 5 collides with the bottom 21b of the bag-like nonwoven fabric 21 or passes through the bottom 21b and collides with the mist receiver 16 to be attached and captured. The oil mist dropped and captured on the bottom 21b is aggregated to become an oil component Q, which is dropped and stored in the mist receiver 16 disposed immediately below. Therefore, the mist receiver 16 is. The oil collecting tray 16 also functions.
In addition, this bag-like nonwoven fabric 21 is attached to the connection portion 18 by using an attachment hardware 22 at the upper end portion.

On the other hand, air that is discharged from the blower 3 and flows along the axial direction of the bag-like nonwoven fabric 21 is blown onto the side wall portion 21a of the bag-like nonwoven fabric 21, and this air is allowed to pass through.
That is, the oil mist pressurized and agglomerated by the blower 3 does not bend abruptly because of its inertia and gravity, and is directed downward. Does not contain much oil mist. Therefore, the cleaned air is discharged from the side wall portion 21a. Even if the oil mist tries to pass through the side wall portion 21a of the bag-like nonwoven fabric 21, the aggregated oil mist is configured to adhere and be captured by the side wall portion 21a. The oil mist is attached and supplemented when it comes into contact with the side wall portion 21a. Therefore, the side roughness of the side wall portion 21a may be such that the oil mist also passes therethrough.

  As shown in FIG. 5, the guide portion 7 is arranged inside the device box 6 so as to surround the side edge portion of the blower 3, and the air including the oil mist is directly accelerated by centrifugal force in the blower 3. A guide plate 23 that is blown and guides air toward the mist capturing chamber 5 is provided.

Next, with reference to FIG.6 and FIG.7, operation | movement of the oil mist removal apparatus 1 of this example is demonstrated.
First, as shown in FIG. 6, the air A including oil mist emitted from the machine tool side is sucked from the intake portion 2 and is fed to the central portion of the blower 3 (inner peripheral portion of the impeller 11) as shown in FIG. 6. It flows in, is pushed by each blade 11a of the impeller 11 and turns, and is pumped in the outer peripheral direction of the impeller 11 through a gap between the blade 11a and the blade 11a.

Here, the air containing the oil mist is directly blown to the guide plate 23 disposed inside the device box 6 so as to surround the side edge of the blower 3 by being accelerated by the centrifugal force in the blower 3. Guided to the capture chamber 5.
A part of the oil mist contained in the air directly blown onto the guide plate 23 collides with the guide plate 23 and is attached and removed.

As shown in FIG. 7, the oil mist aggregated by the suction and pressurization by the blower 3 and contained in the air guided to the mist capturing chamber 5 is along the axial direction of the bag-like nonwoven fabric 21 due to its inertia and gravity. Since many components that go straight forward are included, the bag-shaped nonwoven fabric 21 is directed to the bottom 21b at the lower end, so that the air exhausted from the side wall 21a does not contain much oil mist. Therefore, clean air is exhausted from the side wall 21a.
In the mist trapping chamber 5, the oil mist that has fallen and trapped on the bottom 21 b aggregates to become an oil component Q, and is dropped and stored in the mist receiver 16 disposed immediately below.
The control unit 8 changes the suction force of the blower 3 in accordance with the amount of oil mist generated by the machine tool, and the most effective oil mist removal is performed.

Therefore, according to the configuration of this example, air is sucked and pressurized from the outside, the mist contained in the sucked air is compressed and agglomerated into large particles, and then mainly collided with the mist receiver 16. Since it is configured to adhere and remove, an inexpensive filter material having a relatively rough texture can be used.
Therefore, since the oil mist can be removed with a simple configuration, it is possible to contribute to cost reduction, size reduction, and weight reduction.

  As a second embodiment, as shown in FIG. 8, if a prefilter 24 is added to the first stage of the apparatus, oil mist can be removed more reliably than in the configuration of FIG. As the pre-filter 25, for example, a porous nickel metal filter obtained by impregnating foamed urethane with nickel powder and sintering them is suitable.

FIG. 9 is a sectional view showing a schematic configuration of an oil mist removing apparatus according to a third embodiment of the present invention.
The apparatus configuration of this example is greatly different from that of the above-described second embodiment in that an adsorption sheet for adsorbing oil mist is disposed on the blower side of the guide plate.
Since the configuration other than this is substantially the same as the configuration of the second embodiment described above, the description thereof will be simplified.

In this example, a long adsorbing sheet 41 made of, for example, a woven fabric that adsorbs oil mist is adhered and arranged on the guide plate 23 side of the guide portion 7A so as to surround the side edge of the blower 3. ing.
The adsorbing sheet 41 is made of, for example, a yarn made of a polymer material in a plain weave, and is disposed at a position where oil mist or the like in the air is directly blown by centrifugal force in the blower 3. Here, a part of the oil mist is adsorbed to the adsorption sheet 41 by centrifugal force, but the remaining oil mist rides on the air flow and flows toward the mist capturing chamber 5A. In general, in the guide portion 7A, the opening leading to the cylindrical connecting portion 18 is preferably not closed by the suction sheet 41, although it depends on air permeability.

  Thus, according to the configuration of this example, since the suction sheet 41 is arranged, even a small amount of oil mist that has not been removed by the prefilter 24 is accelerated by the centrifugal force in the blower 3 and collides with the sheet 41. Further, the oil mist can be removed more reliably.

FIG. 10 is a sectional view showing a schematic configuration of an oil mist removing apparatus 1D according to the fourth embodiment of the present invention.
As shown in the figure, the oil mist removing device of this example has a blower 3 that sucks air and air that has been pressurized and accelerated by the blower 3, and removes mist contained in the flowed-in air. The mist capturing chamber 5B is configured to discharge the air. The mist capturing chamber 5B includes a narrow inlet 21c that allows the pressurized air to flow at high speed, and a mist receiver 16 that receives mist or mist droplets. It comprises a bag-like nonwoven fabric (filter member) 21 that surrounds a predetermined space between the inflow port 21c and the mist receiver 16 and attaches and captures mist in the exhausted air.

  Here, the cross-sectional area of the inlet 21c of the bag-shaped nonwoven fabric 21 is 1/20 of the cross-sectional area of the surrounding space defined by the bag-shaped nonwoven fabric 21 (that is, the average cross-sectional area of the central portion of the bag-shaped nonwoven fabric 21). It is preferably set in the range of -1/5.

  According to the said structure, the pressurized air which flows in via the inflow port 21c from the air blower 3 carries out adiabatic expansion in the bag-like nonwoven fabric 21, As a result, mist aggregates and is a floating state or a scattering state in external air In comparison with the case where it is present, the size is increased, so that it is easily captured by the bag-like nonwoven fabric 21.

  Therefore, according to the configuration of this example, the mist taken from the outside is pressure-aggregated by the blower 3 and further granulated by adiabatic expansion, so that the rough and inexpensive bag-shaped nonwoven fabric 21 is used. Even so, oil mist can be reliably removed.

FIG. 11 is a sectional view showing a schematic configuration of an oil mist removing apparatus 1E according to the fifth embodiment of the present invention. The mist capturing chamber 5C of this example is different from that of the fourth embodiment described above in that a tubular nonwoven fabric (filter member) 26 with both ends open is used instead of the bag-like nonwoven fabric (filter member) 21 in the fourth embodiment. This is the point that is used.
Also in the fourth embodiment, substantially the same effect can be obtained as described in the fourth embodiment.

  In the method of capturing by causing the mist receiver 16 to collide with the mist receiver 16, the configuration of the first embodiment (FIG. 1) can be modified to the configuration shown in FIG. In such a configuration, the mist that has flowed in from the blower 3 at high speed directly collides with the mist receiver 16 and is attached and captured.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention.
For example, although the case where it uses in a factory etc. was described, it is not restricted to this, For example, you may use in restaurants, such as a yakiniku restaurant, and a general household.
In addition to the forward-facing blade, the blade shape of the blower can be applied to a radially-oriented blade shape or a backward-facing blade shape.
In addition, the oil mist removing device is not limited to hanging from the ceiling, but may be stationary, or may be not only local exhaust but also wide-area exhaust.

  Moreover, although the case where a bag-like non-woven fabric is used as the filter member has been described in the above-described embodiment, the non-woven fabric is not limited to a synthetic resin, and may be made of paper. But it ’s okay. Further, a porous foam such as a polyurethane foam may be used.

In addition, the filter member may be disposed in the horizontal direction or obliquely downward without hanging vertically downward, or a bent portion or the like may be provided in the middle.
Moreover, in Example 3, the fiber material of the adsorption sheet 41 may use a hollow fiber or the like. Further, for example, a paper non-woven fabric may be used, or a porous foam such as a polyurethane foam may be used.
Furthermore, in the mist trapping chamber, a method of capturing the mist by colliding with the mist receiver and a trapping method by adiabatic expansion can be combined and applied.

  The mist teaching apparatus of the present invention is useful when applied to the removal of ink mist and other mists in addition to oil mists. It can also be applied to the removal of dust such as metal powder in addition to mist.
