Description

  The present invention relates to a dust removing apparatus that mainly removes dust contained in the atmosphere stably over a long period of time and separates and removes dust attached to a filter.

  Conventionally, this type of dust removal device uses a filter to collect dust in the atmosphere when supplying air.However, if dust accumulates in this filter and becomes clogged, the pressure loss increases and the ventilation air volume increases. There was a problem of lowering, and it was necessary to replace or clean the filter regularly. Therefore, a removal method using centrifugal force is known as means for removing clogging of a filter without taking time (see, for example, Patent Document 1).

  Hereinafter, the removal method will be described with reference to FIG. A dust removing device 101 in FIG. 9 is connected to a filter 102 and a motor 103, and includes a suction port 104 and a discharge port 105. The filter 102 is rotatable. When dust in the atmosphere or gas is collected, the dust 106 is collected on the outer peripheral surface of the filter 102 by allowing the gas containing the dust 106 flowing in from the suction port 104 to flow from the outside to the inside of the filter 102. The purified gas flows out from the discharge port 105. And when removing the clogging of the filter 102, the dust adhering to the outer peripheral surface of the filter 102 is wiped off by rotating the filter 102 and utilizing centrifugal force.

  In addition, another conventional dust removing device is known in which a brush is used as a means for removing clogging of a filter without trouble (see, for example, Patent Document 2).

Hereinafter, the removal method will be described with reference to the dust removing device of FIG. The dust removing device 101 in FIG. 10 is connected to a brush 107 whose outer diameter is in sliding contact with the filter 102 and a motor 103 on the inner peripheral side of the filter 102, and includes a suction port 104 and a discharge port 105. The brush 107 is rotatable. It is. When collecting dust in the atmosphere or gas, the dust 106 is collected on the inner peripheral surface of the filter 102 by allowing the gas containing the dust 106 flowing in from the suction port 104 to flow from the inside to the outside of the filter 102. Then, the purified gas flows out from the discharge port 105. Then, when removing the clogging of the filter 102, the brush 107 is rotated and brought into sliding contact with the filter 102, and dust adhering to the inner peripheral surface of the filter 102 is wiped off by using a sweeping force.

It is a block diagram of the other dust removal apparatus.

  1 and 2, the dust removing apparatus includes an outer shell 1 and a filter 3 in which a wire 2 is formed in a mesh shape or a substantially lattice shape inside the outer shell 1, and the filter 3 is disposed on the outer periphery of a circular filter frame 3 a. It is attached in a circle so as to roll. The material of the filter 3 is a resin such as PET or PP, and the thickness, pitch, and lamination of the wire 2 are changed depending on the target dust particle diameter. The center of the diameter of the filter frame 3a is firmly attached to a motor shaft 4a of a motor 4 as a driving means for rotational driving. The motor 4 is attached to the motor frame 4b, and the motor frame 4b is firmly attached to the outer shell 1. ing. Therefore, when the motor 4 is turned on and the motor shaft 4a rotates, the circular filter 3 wound around the filter frame 3a rotates synchronously with the motor shaft 4a. In the embodiment of the present invention, the motor shaft 4a is attached to the center of the diameter of the filter frame 3a. However, the driving means is disposed on the outer periphery of the filter frame 3a or the filter 3, and other than the center of the diameter of the filter frame 3a. There may be a difference between the rotational speed of the driving means and the rotational speed of the filter frame 3a by applying the driving force of the driving means. That is, the drive means may be arranged anywhere as long as the filter 3 can be rotated by the drive means.

  The outer shell 1 has an opening of the windward vent 5a on the windward side 5 with respect to the filter 3 and an opening of the leeward vent 6a on the leeward side 6. The air containing the dust 7 flowing in from the windward vent 5a is It flows in from the outer peripheral side of the shaped filter 3, dust 7 is removed by the filter 3, and flows from the inner peripheral side of the filter 3 to the leeward vent 6 a. On the outer peripheral side of the filter 3, a raking portion 8 is disposed as a raising means having a raking force. The scraping portion 8 has a head portion 9 that reciprocates with a rotating motor 8a, a rotating shaft 8b, a rotating crank 8c, and a rotating roller 8d. When the rotary motor 8a rotates, the rotary shaft 8b rotates, and the head portion 9 reciprocates substantially vertically with respect to the outer peripheral surface of the filter 3 by the rotary crank 8c and the rotary roller 8d. In addition, since the head part 9 should just reciprocate, the head part 9 may reciprocate by another system and another structure. A hair material 9 b is planted on the head contact surface 9 a of the head portion 9. The bristle material 9b is made of a resin such as polyethylene or nylon, has a diameter of several tens to several hundreds of microns, and has a stiffness enough to enter between the wire 2 and the wire 2 of the filter 3. In addition, a dust exhaust blower 10 b having a suction port 10 a on the outer peripheral side of the filter 3 is disposed on the rotation direction side of the filter 3 when viewed from the scraping portion 8. The suction port 10a is located as close as possible to the outside of the filter 3 so that it does not come into contact with the outer periphery. The distance between the outer periphery of the filter 3 and the suction port 10a is about 1 mm. The air containing the dust 7 sucked from the suction port 10a of the dust blower 10b is exhausted from the discharge port 10c. Here, the dust blower 10b is a blower constituted by a centrifugal blade such as a sirocco blade, a turbo blade, or a vortex blade.

  Next, the operation will be described. When a differential pressure is generated on the leeward side 5 and the leeward side 6 so that the static pressure on the leeward side 6 is lower than the static pressure on the leeward side 5, the air containing the dust 7 flows in from the windward vent 5a and is included in the air. The dust 7 is removed by the filter 3, and the purified air flows out from the lee vent 6a. At this time, the motor 4 is not energized and the filter frame 3 a is not rotated by the motor 4. If the dust 7 continues to adhere to the filter 3, the filter 3 becomes clogged and the pressure loss becomes high. Therefore, depending on the degree of adhesion of the dust 7, for the purpose of removing the dust 7 adhering to the filter 3, power is supplied to the motor 4, the rotary motor 8a, and the dust blower 10b once every several tens of hours. To do. The filter 3 fixed to the filter frame 3a by the motor 4 rotates at a relatively slow speed of about 10 to 20 rotations per minute, and at the same time, the rotation motor 8a rotates and rotates at a fast rotation of 500 rotations or more per minute. Dust 7 fixed between the wire 2 and the wire 2 of the filter 3 when the head portion 9 reciprocates at a frequency synchronized with the rotation speed of the rotary motor 8a by the motor 8a, and the head contact surface 9a contacts the filter 3. When the impact force which is the reciprocating kinetic energy of the head contact surface 9a is transmitted to the filter 3, the impact force is directly transmitted to the wire 3 of the filter 3, and the amount of movement of the filter 3 due to the impact is large. The dust 7 separated into two and easily moved does not transmit the impact force directly, and the movement amount of the inertial force due to the impact on the wire 2 is small. Relatively impact force given head contact surface 9a side, that is, easily raised to the outer peripheral surface of the filter 3. Further, the bristle material 9b of the head contact surface 9a contacts the filter 3, enters the wire 2 of the filter 3 and the back of the wire material 2, and scrapes the dust 7 adhering to the filter 3 to the surface of the filter 3. The dust 7 entangled with the wire 2 can be removed. At the same time, the dust 7 scraped to the surface of the filter 3 is sucked from the suction port 10a by the suction force of the dust blower 10b and removed from the outer shell 1 through the discharge port 10c.

  Thus, the dust 7 adhered and accumulated between the wires 2 of the filter 3 is separated from the wire 2 by the impact force of the contact by the reciprocating motion of the head portion 9, and the dust is generated by the contact inertia force and the scraping force by the bristle material 9b. 7 can be lifted to the surface without rubbing into the filter 3 and the dust 7 on the surface of the filter 3 can be removed by the dust blower 10b, so that the maintenance labor and cost of the filter 3 can be reduced. it can.

  In the first embodiment, the scraping portion 8 is arranged on the outer peripheral side of the filter 3 as a lifting means having a scraping force. However, as shown in FIG. The form which arranged the extrusion part 11 as a raising means may be sufficient. The extruding portion 11 has a head portion 9 that reciprocates with a rotating motor 8a, a rotating shaft 8b, a rotating crank 8c, and a rotating roller 8d, and a hair material 9b is planted on the head contact surface 9a of the head portion 9. Here, the distance between the wire 2 and the wire 2 of the filter 3 is relatively large with respect to the diameter of the bristle 9b, and is about 10 times. The dust 7 adhering to the inside of the filter 3 is pushed out from the inner peripheral side of the filter 3 to the outer peripheral side, and the dust 7 is lifted and removed on the outer peripheral surface of the filter 3 and sucked from the suction port 10a by the suction force of the dust blower 10b. And can be removed.

  In the first embodiment, the dust 7 floating on the outer peripheral surface of the filter 3 is removed by the dust blower 10b. However, a dust tray (not shown) is installed in the vicinity of the head portion 9, and the head The dust 7 that freely falls from the filter 3 by the impact force of the unit 9 may be accumulated in a dust tray (not shown), and the accumulated dust 7 may be removed periodically.

  The filter 3 is mounted in a circular shape so as to be wound around the outer periphery of the circular filter frame 3 a, but the upwind vent 5 a on the upwind side 5 and the downwind vent 6 a on the downwind side 6 are short-circuited without passing through the filter 3. If the air that has flowed in from the upwind vent 5a flows out of the downwind vent 6a through the filter 3 instead of the air path that has been formed, the filter 3 may have a flat plate shape (not shown). If the projected area of the head contact surface 9a of 9 is the same as the projected area of the filter 3, or if the scraping part 8 or the pushing part 11 slides on the projected area of the filter 3 (not shown), the same An effect can be obtained.

(Embodiment 2)
The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The configuration of the main body will be described with reference to FIGS.

  FIG. 4 is a configuration diagram of the dust removing device according to Embodiment 2 of the present invention.

  In FIG. 4, an arm portion 12 is disposed on the outer peripheral side of the filter 3 as a lifting means having impact force. The arm portion 12 has a spring portion 12a made of a spring material, and is connected to a rotating shaft 12c that is a rotating portion of the rotating motor 12b. When the rotating motor 12b rotates, the arm portion 12 rotates about the rotating shaft of the rotating shaft 12c. Then, the filter 3 is brought into rotational contact. The rotating arm portion 12 is brought into contact with the overhanging portion 13 as a collision acceleration means within the rotation radius of the arm portion 12 and before the arm portion 12 is brought into rotational contact with the filter 3. FIG. 5 and FIG. 6 show the shape of the arm portion 12. FIG. 5 shows a wire spring 12d having a diameter of the spring portion 12a of about 0.6 mm. FIG. 6 has a plurality of small holes 12e in the arm portion 12, and the spring portion 12a has a plate thickness of about 0.2 t. The leaf spring 12f is used. The diameter or plate thickness of the spring portion 12a is not limited to the above as long as it is a rotary motor 12b having a torque that continues to rotate even after the arm portion 12 contacts the filter 3 or the overhanging portion 13. A dust exhaust blower 10 b having a suction port 10 a on the outer peripheral side of the filter 3 is disposed on the rotation direction side of the filter 3 when viewed from the arm portion 12.

  Next, the operation will be described. When a differential pressure is generated on the leeward side 5 and the leeward side 6 so that the static pressure on the leeward side 6 is lower than the static pressure on the leeward side 5, the air containing the dust 7 flows in from the windward vent 5a and is included in the air. The dust 7 is removed by the filter 3, and the purified air flows out from the lee vent 6a. At this time, the motor 4 is not energized and the filter frame 3 a is not rotated by the motor 4. If the dust 7 continues to adhere to the filter 3, the filter 3 becomes clogged and the pressure loss becomes high. Therefore, depending on the degree of adhesion of dust 7, for the purpose of removing dust 7 adhering to filter 3, power is supplied to motor 4, rotary motor 12b and dust blower 10b once every several tens of hours. To do. The filter 3 fixed to the filter frame 3a by the motor 4 rotates with a relatively slow rotation of about 10 to 20 rotations per minute, and the rotation motor 12b rotates and rotates at a rapid rotation of 1000 rotations or more at the same time. The arm portion 12 is rotated by the motor 12b at a rotational speed synchronized with the rotational speed of the rotary motor 12b, and the arm portion 12 contacts the projecting portion 13 so that the repulsive force and rotation accumulated in the spring portion 12a of the arm portion 12 are rotated. The arm portion 12 comes into contact with the filter 3 with the impact force of the resultant rotational force of the motor 12b. The dust 7 fixed between the wire 2 and the wire 2 of the filter 3 can be separated by this impact force, and the dust 7 that floats on the surface of the filter 3 and is entangled with the wire 2 of the filter 3 can be removed. Even after the arm portion 12 comes into contact with the filter 3, the arm portion 12 continues to rotate by the rotary motor 12b, but absorbs the repulsive force contacted by the spring portion 12a of the arm portion 12, so that the arm connected to the rotary motor 12b. The part 12 continues to rotate continuously, and the arm part 12 contacts the filter 3 one after another. Here, if the spring portion 12a is a wire spring 12d as shown in FIG. 5, the motor torque of the rotary motor 12b can be made relatively small, but if the rotation speed of the arm portion 12 and the rotation speed of the filter 3 are multiplied by a constant, the arm Since the part 12 contacts the same part of the surface of the filter 3 and cannot contact the entire surface of the filter 3, the removal spots of the dust 7 are likely to remain. As shown in FIG. 6, the spring portion 12a is a leaf spring 12f having a plurality of small holes 12e, so that the entire surface of the filter 3 can be contacted, and the removal of dust 7 is difficult to occur and the removal is good. is there.

  As described above, the dust 7 adhered and accumulated between the wires 2 of the filter 3 is separated from the wire 2 by the impact force of continuous contact caused by the rotation, based on the rotational motion of the arm portion 12 and the repulsive force accumulated in the spring portion 12a. The dust 7 can be lifted and removed on the surface of the filter 3 without being rubbed into the filter 3, and the dust 7 on the surface of the filter 3 can be removed by the dust blower 10b. Can be reduced.

(Embodiment 3)

The stabbing portion 14c is made of a resin such as polyethylene or nylon, and has a diameter of several tens to several hundreds of microns and has a stiffness enough to enter between the wire 2 and the wire 2 of the filter 3.

  Further, inside the filter 3, a centrifugal blowing blade 15 having a centrifugal blade such as a sirocco blade or a turbo blade fixed to the filter 3 is fixed to the filter frame 3a. The center of the diameter of the filter frame 3a is firmly attached to the shaft 4a of the motor 4 as the driving means. The motor 4 is attached to the motor frame 4b, and the motor frame 4b is firmly attached to the outer shell 1. On the outside of the filter 3, a casing 15b having an air passage 15a extending in the direction of rotation of the centrifugal air blowing blade 15 is disposed. Therefore, when the motor 4 is turned on and the motor shaft 4a rotates, the rotational motion of the filter 3 is transmitted to the roller portion 14 via the roller contact surface 14a that is in contact with the filter 3, and rotates. On the other hand, the centrifugal blower blades 15 fixed to the filter frame 3a rotate in synchronization with the motor shaft 4a, so that air can flow from the leeward vent 6a and air can flow out to the leeward vent 5a.

  Next, the operation will be described. When a differential pressure is generated on the leeward side 5 and the leeward side 6 so that the static pressure on the leeward side 6 is lower than the static pressure on the leeward side 5, the air containing the dust 7 flows in from the windward vent 5a and is included in the air. The dust 7 is removed by the filter 3, and the purified air flows out from the lee vent 6a. At this time, the motor 4 is not energized and the filter frame 3 a is not rotated by the motor 4. If the dust 7 continues to adhere to the filter 3, the filter 3 becomes clogged and the pressure loss becomes high. Therefore, although depending on the degree of adhesion of the dust 7, for the purpose of removing the dust 7 adhering to the filter 3, the motor 4 is turned on once every several tens of hours. At this time, the operation of a fan (not shown) or the like that generates a differential pressure is stopped so that the static pressure on the leeward side 6 is lower than the static pressure on the leeward side 5. The filter 3 and the centrifugal blower blade 15 fixed to the filter frame 3a by the motor 4 rotate at a speed of 500 revolutions or more per minute. Along with the rotation, the roller portion 14 rotates while giving an impact force to the filter 3 by the uneven portion 14b of the roller contact surface 14a, and the dust 7 fixed between the wire 2 and the wire 2 of the filter 3 is separated by this impact force. To do. Further, the stabbed portion 14c of the roller contact surface 14a contacts the filter 3, enters the wire 2 of the filter 3 and the back of the wire 2, and scrapes the dust 7 adhering to the filter 3 to the surface of the filter 3. The dust 7 entangled with the wire 2 can be removed. At the same time, the dust 7 scraped on the surface of the filter 3 is blown off from the surface of the filter 3 by the centrifugal force and the blowing force generated by the rotation of the centrifugal blower blades 15 and spreads the air passage 15a in the rotation direction. It is discharged from the windward vent 5a through the casing 15b.

  Thus, the rotation of the motor 4 causes the roller portion 14 to rotate, and the contact inertia force that separates the dust 7 adhered and accumulated between the wire rods 2 of the filter 3 from the wire rod 2 by the impact force of the concavo-convex portion 14b, and the insertion force. The dust 7 can be lifted to the surface without being rubbed into the filter 3 by the scraping force by the bristles 14 c, and the dust 7 on the surface of the filter 3 can be removed by the centrifugal force and the blowing force of the centrifugal blowing blade 15. The labor and cost of maintenance of the filter 3 can be reduced.

(Embodiment 4)
The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The configuration of the main body will be described with reference to FIG.

  FIG. 8 is a configuration diagram of a dust removal system according to Embodiment 4 of the present invention.

  In FIG. 8, the dust removing device 17 having the filter 3 and the lifting means 16 connects the duct 18a communicating with the outdoor 18 to the outdoor side vent 17a and connects the duct 19a communicating with the indoor 19 to the indoor side vent 17b. Then, an air supply blower 20 for supplying air from the outdoor 18 to the indoor 19 is disposed in the middle of the duct 19a, and the dust floating on the filter 3 by the lifting means 16 is sucked from the suction port 10a, and the dust discharge duct is discharged from the discharge port 10c. The dust blower 10b for discharging to the outdoor 18 through 10d is provided.

  By operating the air supply blower 20, the air in the outdoor 18 is supplied to the indoor 19. At the same time, the dust 7 contained in the air in the outdoor 18 is taken in from the outdoor vent 17 a. Dust 7 sucked from the outdoor side air vent 17a is removed by the filter 3. However, when the dust 7 is gradually accumulated, the filter 3 is clogged by the dust 7, and the pressure loss becomes high, and the air supply blower 20 makes various requests. The supply air volume cannot be obtained.

  Therefore, although it differs depending on the degree of adhesion of the dust 7, for the purpose of removing the dust 7 adhering to the filter 3, the embossing means having at least one of an impact force, a scraping force, and an extruding force once every several tens of hours. 16 is operated, and the dust 7 that is lifted and removed from the surface of the filter 3 is discharged to the outdoors 18 by the dust blower 10b through the dust discharge duct 10d. Thereby, the clogging of the filter 3 by the dust 7 is eliminated, and a dust removing system that maintains a stable air supply by the air supply blower 20 can be achieved.

  The dust removing device of the present invention is useful for collecting and purifying floating dust when supplying outdoor air for ventilation and air conditioning of a building. Further, the present invention can be applied to an air conditioner or an air purifier that is used while circulating indoor air.
