うにしたものは公知である。(Prior art) Bypass piping between the discharge side piping and suction side piping of a suction pressure source such as a conventional vacuum pump, and by providing an opening / closing valve in the bypass piping, the suction side of the suction pressure source becomes abnormally negative pressure. It is known to open the on-off valve to return the discharge air to the suction side when the above occurs, thereby suppressing the occurrence of cavitation in the suction pressure source and reducing the intake noise.

ることになる。By the way, when a dust storage tank with a suction pipe connected to a vehicle is placed and the dust is sucked together with air into the dust storage tank via the suction pipe by a dust suction device, dust and air are discharged near the discharge port of the dust storage tank. A screen is required to separate the two. Furthermore, since the air that has passed through this screen contains fine dust, a suction pressure source is connected to the discharge pipe through a separate dust removal filter.

Pipe the filter, suction pressure source, and silencer sequentially, and bypass the suction side of the suction pressure source between the discharge side and suction side piping through an on-off valve to prevent the suction side of the suction pressure source from becoming an abnormal negative pressure. In that case, the on-off valve is opened to prevent destruction of the dust storage tank and the screen.

Abnormal negative pressure on the suction side is prevented. Since this air has once passed through the filter portion, there is no feeling that fine dust is caught in the suction pressure source and damages the suction pressure source. Then, by releasing the abnormal negative pressure, it is possible to prevent the dust storage tank and the screen from being destroyed.

くなされている。CB is a control device that receives a signal from the pressure detector 14 and outputs an opening / closing command to the opening / closing valve 13 based on this signal. That is, the control device CB closes the open / close valve 13 when the suction side pressure becomes equal to or lower than the predetermined lower limit pressure value P 1 and the command to open the open / close valve 13 becomes equal to or higher than the predetermined upper limit pressure value P 2. The commands to cause each are issued.
以下シュートＳに投棄されてごみ貯留タンクＴに溜まっ
たごみをごみ収容タンク２に吸引する場合の概略動作を
説明する。Hereinafter, a schematic operation in the case of sucking the dust dumped in the chute S and accumulated in the dust storage tank T into the dust storage tank 2 will be described.

る。First, it is assumed that the open / close valves V 1 and V 3 are closed and only the open / close valve V 2 is open. Therefore, the operator stops the dust suction wheel with the suction pipe VP in the retracted state as shown in FIG. 1 at a predetermined position near the discharge pipe H as shown in FIG. Then, the manhole cover of the discharge pipe H is removed, and the suction pipe VP is operated to dock the tip end thereof to the discharge pipe H. Then closing valve V 2, V 3 is closed and only the on-off valve V 1 open.

んである。Then, the suction pressure source 11 is driven to make the suction side from the waste storage tank T to the suction pressure source 11 negative pressure. Moreover, the pressure is detected by the pressure detector 14, and the value is input to the control device CB. An open / close command is output to the open / close valve 13 so that the value falls between the predetermined P 1 value and P 2 value. When the on-off valve 13 is opened, the discharge air of the suction pressure source 11 is bypassed to the pipe 9b via the pipe 9d, so that the compressed air purified by the filter unit 10 returns to the suction pressure source 11. become. Therefore, there is no hurry that foreign matter is mixed in the suction pressure source 11. Moreover, the response of the pressure control is good, the hysteresis can be suppressed low, and the noise is also low.

場合は、前述動作を繰返せばよい。When the suction side pressure reaches a predetermined pressure value, the on-off valve V 3 is opened. Then, air is introduced into the waste storage tank T, and the waste in the waste storage tank T is sucked into the waste storage chamber R 1 of the waste storage tank 2 together with the air. The dust and the air are separated by the screen 7, and the air (including fine dust) is cleaned by the filter section and is exhausted to the outside. If all the dust cannot be sucked in by one suction operation, the above operation may be repeated.

ば、ごみを排出することができる。When the amount of dust sucked into the dust storage tank 2 is full, the suction pipe VP is swung from the storage position shown in FIG. Evacuate to a position that does not interfere with opening and closing operations. Then, by opening the opening / closing door 3 and tilting the dust storage tank 2 rearward, the dust can be discharged.

装置の耐久性向上にも有効である。(Effects of the Invention) As described above, the suction pressure source 11 sucks clean air to prevent damage to the pressure source, and even when the suction pipe VP is clogged with dust, suction is performed. Rather than the pressure source 11, it is possible to prevent the dust storage tank 2 and the screen, which have difficulty in rigidity, from being broken, and it is also effective in improving the durability of the dust suction device.
