As shown in FIG. 1, the cleaning device 10 according to the first embodiment of the present invention is an asbestos that is an example of an asbestos-containing building material (construction target) in which white asbestos (chrysotile) that is difficult to scatter is used. The asbestos dust generated at the time of removing the slate plate 11 (see FIG. 3) sucks and removes dust mixed with foreign matter nails 12 (fasteners of the asbestos slate plate 11). The suction port 14 has a handling pipe 15 formed at the tip, and a cleaner body 17 connected to the pipe 15 via a long vacuum hose 16. For example, a foreign matter removing means 18 for removing the nail 12 from the waste in a floor-mounted type is provided. This will be described in detail below.

The brush 13 is provided so as to protrude from the outer peripheral side surface of the distal end portion of the pipe 15 toward the distal end side, thereby facilitating suction by applying external force to the asbestos dust adhering to the asbestos slate plate 11.
The pipe 15 is made of plastic, for example, and its length is adjusted by attaching an extension pipe. A dust scattering prevention cover (an example of a cover) 19 is attached to the tip of the pipe 15 so as to cover an asbestos dust generation part (dust generation part) in the removal work of the asbestos slate plate 11.

The dust scattering prevention cover 19 has a dome-shaped hood 22 formed of a film-like transparent member (for example, polypropylene, vinyl chloride, etc.), and an opening is formed in a part (side part) of the hood 22. 20 is provided, and a pipe insertion portion 21 is formed in close contact with the side surface of the pipe 15 inserted through the tip portion of the pipe 15. The dust scattering prevention cover 19 includes a reinforcing portion 23 that is attached to the lower peripheral edge of the hood 22 and the edge of the opening 20 and is formed from a resilient member (for example, rubber, sponge, etc.). In addition, the dust scattering prevention cover 19 is provided with a shape holding member (not shown) such as a wire that contacts the inner surface of the hood 22 and holds the hood 22 in a dome shape.

By adopting such a configuration, the dust scattering prevention cover 19 is arranged so that the nail 12 fixing the asbestos slate plate 11 to be removed to the roof plate 24 (see FIG. 3) comes to the center. Thus, asbestos dust can be covered with the hood 22. Then, a nail removal tool 25, which is an example of a removal tool placed on the asbestos slate plate 11, is inserted from the opening 20 of the dust scattering prevention cover 19, and the head of the nail 12 is sandwiched between the operation parts of the nail removal tool 25. The nail 12 can be pulled out. Moreover, since the pipe 15 inserted from the pipe insertion part 21 can be swung and moved forward and backward with respect to the dust scattering prevention cover 19, the position of the suction port 14 at the tip of the pipe 15 can be freely adjusted. And asbestos dust generated when the asbestos slate plate 11 is removed can be easily sucked.

As shown in FIG. 2, the foreign matter removing means 18 includes, for example, a storage portion 26 that has a rectangular parallelepiped shape and has an opening formed in an upper portion thereof, and a lid portion 28 that closes the opening of the storage portion 26 via a packing 27. Yes. And the accommodating part 26 is comprised with the transparent member (for example, polypropylene, vinyl chloride, etc.). Thereby, the quantity of the nail 12 accommodated in the accommodating part 26 can be confirmed easily. Here, an insertion hole 28a for inserting a tip portion of a water jet nozzle (not shown) into the storage portion 26 is provided on the side surface of the storage portion 26, and a lid 28b is attached to the insertion hole 28a.
The lid portion 28 is provided with a suction portion 29 connected to the upstream side of the vacuum hose 16 and communicating with the storage portion 26, and a discharge portion 30 communicating with the storage portion 26 and connected to the downstream side of the vacuum hose 16. .

The suction portion 29 is attached to the lid portion 28 via the first attachment member 31 at one end side, and the suction portion 29 is attached to the other end side of the first elbow 32 and connected to the vacuum hose 16. It has a side pipe 33 and an outlet side pipe 34 attached to the first attachment member 31 and communicating with one end side of the first elbow 32. Further, the discharge unit 30 is connected to the vacuum hose 16 by being attached to the second elbow 36 whose one end is fixed to the lid 28 via the second attachment member 35 and the other end of the second elbow 36. And a discharge pipe 37. The flow passage cross-sectional area of the storage portion 26 is rapidly enlarged with respect to the flow passage cross-sectional area of the suction portion 29 (for example, 40 to 60 times the flow passage cross-sectional area of the suction portion 29). Thereby, the wind speed of the airflow flowing into the storage portion 26 from the outlet of the suction portion 29 can be drastically reduced.

A separation plate 38 is provided on the inner side of the lid portion 28 through a plurality of support members 38 a having a gap with the inner surface of the storage portion 26, and only the front side of the outlet pipe 34 of the suction portion 29 is the separation plate. 38 is penetrated. Further, a separation mesh member 38 b protrudes from the outer peripheral portion of the separation plate 38, and a tip portion thereof is in contact with the inner surface of the storage portion 26.
By adopting such a configuration, when the air flow including the dust flows into the storage portion 26 from the outlet of the suction portion 29, the wind speed of the air flow rapidly decreases and the nail 12 sinks to the bottom of the storage portion 26, The air stream entraining the dust after the nail 12 is removed passes through the separation mesh member 38b provided in the gap between the separation plate 38 and the inner surface of the storage portion 26 and flows into the inlet of the discharge portion 30. The presence of the separation plate 38 prevents the nail 12 that has settled at the bottom of the storage unit 26 from being swung up by the airflow and flowing into the inlet of the discharge unit 30.

The vacuum cleaner main body 17 is replaceably attached to a suction port 39 to which the base of the vacuum hose 16 is connected, and includes a bag-shaped collection filter 40 that collects garbage after the nail 12 is removed. 1 collection unit 41, an exhaust unit 42 provided above the first collection unit 41 and exhausting the air in the collection filter 40 to the outside, and the discharge side of the cleaner body 17 And a second collection portion 43 that removes the air that has passed through the collection filter 40 with a finer filter and exhausts the air from the discharge port. In the collection filter 40, since only the dust after the nail 12 is removed is collected, the suction ability as the cleaner body 17 can be maintained for a long time. Furthermore, since the nail 12 does not enter the collection filter 40, the collection filter 40 can be prevented from being damaged.

Next, a dust removal method using the cleaning device 10 according to the first embodiment of the present invention will be described.
As shown in FIGS. 1 and 3, asbestos dust is generated when the nail 12 is removed by the nail removal tool 25 in the removal operation of the asbestos slate plate 11 that is nailed to the roof plate 24. Therefore, the periphery of the nail 12 is covered with a dust scattering prevention cover 19 attached to the tip of the pipe 15, and the suction port 14 at the tip of the pipe 15 is disposed close to the nail 12 fixing the asbestos slate plate 11. . Then, the vacuum cleaner main body 17 disposed on the mounting table 44 is operated to suck the air in the dust scattering prevention cover 19 from the suction port 14, and the nail removal tool 25 (operation part) is inserted from the opening 20 to Pull 12 out. At this time, the generated asbestos dust can be collected by the cleaner body 17, and the asbestos dust can be prevented from being scattered to the outside. In addition, since the cleaner body 17 is disposed at a high place, the cleaner body 17 is fixed to the mounting table 44 by a fixing member (not shown).

Here, the nail 12 pulled out by the brush 13 provided in the suction port 14 can be prevented from being sucked, but the nail 12 is sucked together with asbestos dust because the suction port 14 is close to the nail 12. Sometimes. When the nail 12 is sucked from the suction port 14, the dust in a state where the asbestos dust and the nail 12 which is a foreign object are mixed is transferred through the vacuum hose 16.

As shown in FIG. 2, the dust transferred through the vacuum hose 16 enters from the inlet pipe 33 provided in the suction part 29 of the foreign matter removing means 18, and enters the storage part 26 from the outlet of the outlet pipe 34. To be discharged. Here, since the flow passage cross-sectional area of the storage portion 26 is rapidly increased with respect to the flow passage cross-sectional area of the suction portion 29, the wind speed of the airflow flowing in from the outlet of the outlet side pipe 34 rapidly decreases. For this reason, the nail 12 is separated from the airflow and settles to the bottom of the storage portion 26 and is removed. Then, the airflow containing asbestos dust passes through the gap formed between the separation plate 38 and the side wall of the storage unit 26 and flows into the inlet of the second elbow 36 provided in the discharge unit 30. . Here, the presence of the separation plate 38 causes the nail 12 that has settled to the bottom of the storage portion 26 to be swung up by the airflow, and enters the vacuum hose 16 from the inlet of the second elbow 36 provided in the discharge portion 30. Inflow can be prevented.

As shown in FIG. 3, the nail 12 is separated and removed by the storage portion 26, so that the asbestos slate plate 11 is removed from the roof plate 24, and the removal work place is located in the cleaner body 17. When a part of the long vacuum hose 16 is approached and a slack portion 44a is formed hanging down from the roof, for example, the suction port 14 is in close contact with the asbestos slate plate 11 during suction, and the suction air volume is rapidly increased. Even if it decreases or even if dust gradually accumulates in the vacuum cleaner main body 17 and the suction air volume decreases, there is a situation in which the nail 12 gathers in the slack portion 44a and the vacuum hose 16 is closed and suction becomes impossible at once. Can be prevented.

The airflow containing asbestos dust discharged from the discharge part 30 of the foreign matter removing means 18 into the vacuum hose 16 flows into the collection filter 40 of the first collection part 41 from the suction port 39 of the cleaner body 17. . When the air flow containing asbestos dust passes through the collection filter 40, the asbestos dust is captured by the collection filter 40, and the air flow that has passed through the collection filter 40 passes through the filter of the second collection unit 43. And then released into the atmosphere from the outlet. For this reason, even if there is asbestos dust of a size that cannot be collected by the collection filter 40 in the airflow that has passed through the collection filter 40, it can be collected by the second collection unit 43. An air stream that does not contain water can be released into the atmosphere.

Here, since the accommodating part 26 is comprised with the transparent member, the quantity of the nail | pipe 12 accumulated in the accommodating part 26 can be confirmed easily. When the nail 12 accumulates in the storage portion 26, the pulling-out operation of the nail 12 is interrupted, the vacuum hose 16 connected to the suction portion 29 and the discharge portion 30 is removed, and the storage portion 26 in use is covered with the lid portion. Remove with 28 attached. And the vacuum hose 16 is connected to the suction part and discharge part of the cover part attached to another accommodating part, respectively, and the extraction operation | work of the nail 12 is restarted.

The storage unit 26 removed with the cover 28 attached is transported to the collection place of the nail 12 with the inlet side of the suction unit 29 and the outlet side of the discharge unit 30 closed. Then, the lid 28b covering the insertion hole 28a is removed, the tip of the water jet nozzle is inserted into the storage portion 26 from the insertion hole 28a, and water is sprayed, and each inner surface of the lid portion 28 and the storage portion 26 is injected. The asbestos dust adhering to the nails 12 is prevented from scattering. Next, the pressing member 45 holding the lid portion 28 is removed, the lid portion 28 is removed, the nail 12 is taken out, and the asbestos dust attached to the nail 12, the lid portion 28, and the storage portion 26 is removed.

The cleaning device 46 according to the second embodiment of the present invention is different from the cleaning device 10 according to the first embodiment in that the configuration of the floor-mounted foreign matter removing means 47 is different. Yes. For this reason, only the foreign matter removing means 47 will be described in detail, and the same constituent members will be denoted by the same reference numerals and description thereof will be omitted.
As shown in FIG. 4, the foreign matter removing means 47 is, for example, a bottle-shaped storage that draws and stores a net-like filter 48 and a nail 12 that is a foreign matter that does not pass through the filter 48 from a protruding storage opening (opening) 49. Part 50.

Further, the foreign matter removing means 47 has a female screw portion that meshes with a male screw portion formed outside the storage port 49 and has a lid portion 51 that is screwed into the storage port 49 and closes the storage port 49. . The lid portion 51 is provided with a tubular suction portion 52 that is connected to the upstream side of the vacuum hose 16 and communicates with the storage portion 50, and an opening portion 53 is formed in the middle of the suction portion 52. A tubular discharge portion 54 connected to the downstream side of the vacuum hose 16 is connected in a branched state. Further, the opening 53 serving as the inlet of the discharge unit 54 is covered with a filter 48. Here, the accommodating part 50 is comprised by the transparent member (for example, polypropylene, vinyl chloride, etc.). Thereby, the quantity of the nail 12 accommodated in the accommodating part 50 can be confirmed easily.

With this configuration, when the cleaner main body 17 is operated, dust mixed with asbestos dust and the nail 12 that is a foreign object is sucked and passes through the vacuum hose 16 and enters the suction portion 52. Here, since the direction of the airflow involving the asbestos dust and the nail 12 changes suddenly when passing through the opening 53, the asbestos dust is caught in the airflow, passes through the filter 48, and is discharged from the opening 53 to the discharge portion 54. However, the nail 12 cannot pass through the opening 53 due to its own inertia and the presence of the filter 48, and the nail 12 passes through the suction portion 52 and flows into the storage portion 50 to be separated and removed. Is done.

Since the method for removing dust using the cleaning device 46 according to the second embodiment of the present invention is substantially the same as the method for removing dust using the cleaning device 10 according to the first embodiment of the present invention. The description of the dust removal method using the cleaning device 46 is omitted.
