At the front of the suction box 3, water is sprayed from the water spray nozzle 4 onto the asbestos that has fallen and accumulated on the floor, and at the same time the rotary brush 5 is rotated by the drive motor 7, and the asbestos is removed by the rotary brush 5 into the suction box 3. It is configured to sweep asbestos into the rear part of the interior and suck asbestos there from a suction port 6. Note that 8 is a hand handle fixed to the rear end of the suction housing 3, and is used to move the suction attachment A to a desired position.

The asbestos compression and filling devices B and B are arranged opposite to each other, and the explanation will be given for only one of them. That is,
As shown in FIGS. 4 to 7, a substrate 10 with a through hole formed therein is placed on the frame 9, and the lower end is open on the substrate 10 and the inner circumference is slightly smaller than the through hole of the substrate 10. A cylindrical receiver tank 11 having a diameter is fixed by an appropriate means so as to face the through hole of the substrate 11 with its lower edge slightly separated from the upper surface of the substrate 10, and a hole is penetrated into the center of the receiver tank 11. A cyclone 12 is erected on the end plate 11a in which a hole is formed by fitting the lower end of the cyclone 12 into the through hole of the end plate 11a, and the bases are pivoted to the cyclone 12 on both sides of the cyclone 12. A pair of discharge cylinders 13, 13 are disposed facing downward, and the tip portions of piston rods 13a, 13a extend below the discharge cylinders 13, 13, penetrate through the end plate 11a of the receiver tank 11, and are inserted into the inside thereof. A donut-shaped compression discharge plate 14 that is fitted into the receiver tank 11 so as to be able to rise and fall freely and forms a through hole in the center is attached to the receiver tank 11, and a guide rail 15 is installed between the upper surface of the substrate 10 and the lower edge of the receiver tank 11. , 15, a slide door 16 is slidably installed, a shaft 17 is supported at one end of the upper surface of this slide door 16, and a base is pivotally attached to both ends of the board 10 on both sides of the board 10. A pair of sliding door cylinders 18, 18 piston rods 18a,
The tip of 18a is fixed, and the airflow containing asbestos sucked by suction attachment A flows into the cyclone 12, where the asbestos in the airflow falls to the lower part and enters the receiver tank 11. Here, the asbestos is compressed by the compression discharge plate 14 by the discharge cylinders 13, 13, and after repeating this several times, the sliding door 16 is opened by the sliding door cylinders 18, 18, and then the inside of the receiver tank 11 is compressed. Asbestos compressed and deposited in the asbestos is discharged downward by a compression discharge plate 11 by discharge cylinders 13, 13, and packed into a drum 20 disposed inside a frame 9 by a hand lifter 19. In addition, 21 is a hydraulic unit for the discharge cylinders 13, 13 and the sliding door type cylinders 18, 18,
22 is an operation panel; 23 is a three-way switch that communicates between one of the asbestos compression and filling devices B and the suction attachment A; and 24 is a three-way switch that communicates between one of the asbestos compression and filling devices B and the suction wheel C. Switching switch, 25,
Reference numeral 25 denotes a water drain pot installed on the peripheral wall of the receiver tank 11, which drains water exuding from the receiver tank 11 when asbestos is compressed. Receiver tank 1
The water discharged from 1 is once collected in a water tank 26 disposed between asbestos compression and filling devices B, and then supplied to suction attachment A by a pump 27 disposed on suction wheel C. The water is sprayed from the water spray nozzle 5. A suction strainer 28 removes foreign matter from the water sucked from the water tank 26 by the water pump 27.

Suction car C has receiver tank 29 and cyclone 3
0, separator/drainer 31, vacuum pump 32
A pneumatic transport device consisting of a discharge silencer 33 and the like is mounted on a vehicle body such as a truck, and these are connected to a receiver tank 29, a cyclone 30, a separator 31a of a separator/drainer 31, a vacuum pump 32,
The draining device 31b of the separator/draining device 31 and the discharge silencer 33 are connected in series in this order, and the vacuum pump 32 forms an air flow, and the suction attachment A uses this air flow to suck asbestos. In addition to transporting the asbestos to the asbestos compression and filling devices B and B, the air flow containing powdered asbestos that was not recovered by the asbestos compression and filling devices B and B is transferred to the receiver tank 29.
The asbestos powder in the airflow flows into the cyclone 30, where it falls and is collected in the lower chamber 34, and the air discharged from the cyclone 30 is passed through a separator 31a, a vacuum pump 32, a drainer 31b, and a discharge silencer 33. It is configured to pass through, remove dust, drain water, and muffle sound before being released into the atmosphere.
In addition, 35 is a water spray nozzle installed at the inlet of the cyclone 30, which atomizes the water in the chamber 34 sucked up by the water pump 36 and sprays it onto the air flow containing powder asbestos. Moisture is attached to the powdered asbestos to make it heavier so that the powdered asbestos is surely dropped and collected in the cyclone 30. 37
38 is a vacuum breaker, 39 is a load release valve, and 40 is a vacuum gauge.

The asbestos recovery device of the present invention pneumatically transports asbestos from a suction attachment A to an asbestos compression and packing device B, B using a suction vehicle C equipped with a pneumatic transportation device, and collects the asbestos into a drum can. The asbestos recovery work that was previously done can be done mechanically, reducing the labor and time required for the work and improving work efficiency.

In addition, the suction attachment A of the above embodiment is for a floor surface to suck up asbestos that has fallen and accumulated on the floor surface, and
Suction attachment for ceiling wall as shown in Figure 8
By using A', it is possible to scrape off asbestos from the ceiling and walls while also suctioning it.

The ceiling wall suction attachment A' supports a suction tube 43 on a movable frame 42 by a plurality of wheels 41, 41, etc. so as to be adjustable vertically and in elevation, and has a water spray nozzle 44 at the tip thereof. A rotary crushing blade 45 is provided, and while water is sprayed onto asbestos on the ceiling and walls from a water spray nozzle 44 at the tip of the suction cylinder 43, the rotary crushing blade 45 is rotated by a drive motor 46 to generate the rotation. It is configured to scrape off asbestos from the ceiling and walls with a crushing blade 45 and suck this asbestos through a suction tube 43.

Effects of the Invention According to the present invention, asbestos is pneumatically transported from the suction attachment to the asbestos compression and filling device using a conventional suction vehicle equipped with a pneumatic transport device, where it is collected in a drum can, so that the asbestos collection work can be carried out by a machine. This reduces the amount of effort and time required for the work, and improves work efficiency.
