Description

  The present invention relates to a simple dust treatment device that discards generated dust to the outside when, for example, a building or the like is repaired or dismantled.

  Dust is inevitably generated when renovating a building, etc., or scrapping and deconstructing a building. In that case, although it will work while sucking in the dust using a vacuum cleaner, a dust collector, etc., it may not be able to suck in the dust. On the other hand, if dust is forcibly exhausted to the outside using a blower, the dust will be scattered to the outside and adversely affect the surrounding environment. In addition, because of the dust suction operation, a cleaning worker is required in addition to the repair worker, and extra manpower is required.

  Therefore, conventionally, a dust collector for a grain dryer and a dustproof device as described in Patent Documents 1 and 2 are known.

It is a schematic block diagram (A), (B) which shows the other Example of the perforated gutter in the simple dust processing apparatus 1. FIG.

  As shown in FIG. 1 or 2, the simple dust treatment apparatus 1 according to the present invention uses a notch tank for the storage tank 4 to make a water curtain (hereinafter referred to as a water curtain) with a perforated trough 7, It effectively adsorbs and precipitates dust.

  A simple dust treatment apparatus 1 according to the present invention is an apparatus for collecting dust generated from a building, as shown in FIG. 1 or FIG. 2, and a blower 2 disposed at a place where the dust is generated; The one end 3a is connected to the blower 2, and the other end 3b is connected to the duct opening 5a of the lid member 5 that closes a part of the opening at the top of the storage tank 4, and can be expanded and contracted. And a duct 3 having a bellows.

  Furthermore, there is a storage tank 4 that is disposed at the end of the duct 3 and stores the water 6 for collecting dust in the bottom 4a, and a lid member 5 that closes a part of the upper opening of the storage tank 4. . And it is arrange | positioned in the upper opening part of the said storage tank 4 adjacent to the said cover member 5, and the supplied fresh water 6a is dropped from many holes 7b of the dredged bottom part 7a, and it is set as the curtain of fresh water 6a. There is a perforated rod 7 to be dropped at the bottom 4a of the storage tank 4.

  The simple dust treatment apparatus 1 includes a submersible pump 9 that is disposed at the bottom 4a of the storage tank 4 and pumps and supplies the water in the bottom 4a to the perforated trough 7 via a hose 8. It is configured. Hereinafter, details of each component will be described.

  The blower 2, the duct 3, the storage tank 4, the submersible pump 9, and the like are commercially available products or rental products. These are easy-to-acquire items that are appropriately arranged.

  As shown in FIG. 3A, the storage tank 4 is a notch tank having partition plates 4b and 4c erected from the bottom 4a. For example, by providing an orifice in a part of the upper edge of the partition plate 4b, the floating material is prevented from moving to the next section. By the partition plates 4b and 4c, the water 6 stored in the bottom portion 4a is partitioned into a precipitation region where dust has settled and a fresh water region made into clean water without dust.

  On the other hand, what is shown in FIG. 3B is a general water tank 4d without a partition. Since the water tank 4d has no partition, it cannot be divided into the settling area and the fresh water area, and a dust-proof measure such as a filter is necessary for the submersible pump 9 so that the suction port of the pump is not clogged with dust. Is. In the simple dust treatment apparatus 1 according to the present invention, by using a notch tank for the storage tank 4, a water treatment function that is not found in the conventional dust treatment apparatus using the water tank 4d is exhibited.

  As shown in FIG. 1, the storage tank 4 is provided with a caster 10 at a lower portion thereof, and is movable. In this way, in the renovation floor or demolition floor of the building, depending on the progress of the construction, the place where the blower 2 is placed or the place where the duct 3 is laid is stored in an appropriate place. The tank 4 can be moved quickly. Moreover, the bottom part 4a of the storage tank 4 can be provided with a discharge port for discharging the precipitate in the precipitation region. This is because dust or the like accumulated in the sedimentation area can be easily discharged together with sewage.

  As shown in FIG. 1 or FIG. 2, the lid member 5 is a part of the upper opening of the storage tank 4 so that the dust exhausted into the storage tank 4 by the duct 3 does not dissipate outside. To do. The lid member 5 may be a single plate or a combination of divided bodies, and the material thereof is made of metal, plastic, wood, etc., and is not particularly limited.

  As shown in FIGS. 4 to 5, the perforated rod 7 is made of, for example, metal, plastic, wood, and the like, and is formed on the bottom portion 7 a along the longitudinal direction (the left-right direction shown in FIG. 2). A large number of holes 7b are arranged in a staggered arrangement. It is for forming the water curtain of the fresh water 6a.

  The perforated rod 7 is elongated in one direction, and is elongated in the longitudinal direction (left-right direction) as shown in FIG. Moreover, the cross-sectional shape of the perforated ridge 7 in the short direction (front-rear direction shown in FIG. 2) orthogonal to the longitudinal direction which is the one direction is, for example, a concave shape. Not limited to this example, as shown in FIG. 4B, the cross-sectional shape may be a semicircular shape, or may be a semi-elliptical shape, a V shape, etc. Absent.

  Further, the holes 7b are arranged in a staggered arrangement along the longitudinal direction on the bottom 7a of the perforated trough 7, but the arrangement of the holes 7b is not limited to the illustrated example, for example, a lattice shape It can arrange | position to random or arrange | position at random, It does not specifically limit.

  Further, regarding the hole diameter of the hole 7b in the perforated rod 7, for example, as shown in FIG. 4 (A), it is far from the position of the rod bottom portion 7a where water is discharged and supplied from the water supply port 8a of the hose 8. As the distance increases, the diameter of the hole 7b is gradually increased so that a <b <c. This is because as the position of the hole 7b is separated from the water supply port 8a, the amount of water flowing through the bottom 7a decreases. Of course, this does not prevent all the diameters of the holes 7b from being the same.

  As another example of the perforated rod 7, as shown in FIG. 5 (A), the perforated rod 7 is raised in the longitudinal direction (left-right direction) and one end side is raised in the up-down direction so as to be in a single flow. To do. And the water supply port 8a of the hose 8 is arrange | positioned in the high position of the said perforated rod 7. FIG.

  As yet another embodiment, as shown in FIG. 5B, in the central portion of the perforated rod 7 in the longitudinal direction, the “vertical” position is set higher than the vertical position of the left and right end portions. It is also possible to make the perforated trough 7. A water supply port 8a of the hose 8 is disposed at the center of the perforated rod 7 so that the fresh water 6a flows from side to side. In this manner, the flow of the fresh water 6a is accelerated and does not stay due to the inclination of the perforated trough 7.

  In addition to this, although not shown, the elongated perforated rod 7 that is straight in the longitudinal direction is arranged, for example, curved in an arc shape or skewed forward and backward in plan view. You can also. This is because the upper opening of the storage tank 4 can be effectively utilized by appropriately changing the arrangement of the other end 3b of the duct 3 by changing the shape of the water curtain by the perforated trough 7 in various ways. .

  The submersible pump 9 is disposed in a fresh water region in a notch tank that is the water storage tank 4. This is because the clear water 6a in the clear water region is circulated by the submersible pump 9 to the perforated trough 7 through the hose 8.

  As shown in FIG. 1 or FIG. 2, the usage method of the simple dust treatment apparatus 1 according to the present invention configured as described above is configured such that the blower 2 is arranged on the floor where renovation or demolition work is performed in a building. Set up. One end 3 a of the duct 3 is connected to the blower 2, and the other end 3 b is connected to the duct opening 5 a of the external storage tank 4.

  Water 6 is stored in the bottom 4a of the storage tank 4 according to the height of the partition 4b. The submersible pump 9 disposed in the fresh water region is driven. The fresh water 6 a is supplied to the perforated trough 7 through the hose 8 connected to the submersible pump 9.

  The fresh water 6 a falls from the hole 7 b of the perforated trough 7, and a water curtain is formed by the fresh water 6 a over the entire left and right region of the storage tank 4. Therefore, the fan of the blower 2 is driven.

  As shown in FIGS. 1 and 2, dust generated in the building is sucked into the blower 2 and exhausted into the internal space of the storage tank 4. This internal space is a space partitioned by the side wall of the storage tank 4, the lid member 5, the water 6 stored in the bottom 4a, and the water curtain. Then, the dust falls or is adsorbed on the water curtain and settles in the water 6 in the precipitation area.

  The air that has passed through the water curtain is cleaned by removing dust, and is exhausted to the outside. On the other hand, the dust in the sedimentation area settles and accumulates on the bottom 4a, and the contaminated water 6 passes through the partition plates 4b and 4c and becomes the supernatant fresh water 6a to reach the fresh water area. And the fresh water 6a is supplied to the perforated trough 7 through the hose 8 by the said submersible pump 9, and the water 6 is circulated.

  As described above, the dust generated during the renovation / demolition work of the building settles in the notch tank as the storage tank 4 and is collected. The storage tank 4 is moved to an appropriate position by a caster 10 by expanding / contracting / extending the bellows duct 3 according to the progress of the renovation / demolition work of the building. After completion of the renovation and demolition work of the building, the driving of the blower 2 and the submersible pump 9 are stopped, the cover of the drainage port in the bottom 4a of the storage tank 4 is opened, the drainage of the water 6 and the precipitated dust It is collected and disposed of.

  According to the simple dust treatment device 1 according to the present invention, the configuration of the simple dust treatment device 1 can be configured simply by using a commercially available product or by modifying a part of the commercially available product. It can be widely applied to renovation and dismantling of various buildings.
