Description

Detailed description of the invention

  The present invention relates to a sludge recovery device and a sludge recovery vehicle, and more particularly to a sludge recovery device and a sludge recovery vehicle for sucking and recovering sludge, earth and sand, waste liquid, and the like.

  Recovery processing of industrial waste in a fluid state such as sludge, earth and sand, and waste liquid is indispensable for the development of a sound industry by preventing environmental destruction. For this reason, when recovering industrial waste, sludge recovery devices and transport vehicles have been frequently used for the purpose of recovering the sludge and promptly transporting it to a treatment plant.

FIG. 4 shows a conventional example of the sludge recovery device 130 which is this sludge recovery device.
In FIG. 4, a sludge recovery device 130 is mostly mounted on a traveling vehicle body (not shown) so that it can be quickly carried into a treatment site for industrial waste such as sludge, earth and sand, and waste liquid.

  The sludge recovery device 130 has a hopper (tank) 4 for recovering industrial waste such as sludge. A cyclone dust collector 5 for cleaning dirty air flowing from the hopper 4 and a hopper 4 A blower 3 composed of a water-sealed vacuum pump set to a vacuum state and a silencer water tank (silencer) 6 that performs dust removal and noise reduction of air flowing through the blower 3 are provided.

The suction pipe 7 extends through the door portion 16, and has one end projecting into the hopper 4 and an opening / closing valve 8 at the other end projecting outward. In this case, one end side of the suction pipe 7 protruding into the hopper 4 extends to the upper side of the hopper 4 so as to obtain a strong suction force and the suction is not hindered by deposits in the hopper 4.

Next, the operation of the sludge recovery apparatus in this conventional example (FIG. 4) will be described.
First, when the blower 3 is driven, most of the solid matter having a large specific gravity among the collection objects sucked from the suction pipe 7 is stored in the hopper 4 or the cyclone dust collector 5. Specifically, solids or the like having a large specific gravity are stored in the hopper 4, and dust or the like that is a collected material that is dry and has a small specific gravity and cannot be supplemented by the hopper 4 is allowed to pass through the first connecting pipe 9. Is introduced into the cyclone dust collector 5 and captured by the cyclone dust collector 5.

Air contaminated with dust or the like flowing from the cyclone dust collector 5 into the blower 3 through the second connection pipe 10 is introduced into the blower 3 by the suction force of the blower 3, and then the water circulation in the blower 3 Contact.
Thereby, the dust etc. sucked together with the air are captured by the water for sealing.
Thereafter, the air removed by the blower 3 is introduced into the silencer 6 through the third connecting pipe 11, and fine dust is captured by the silencer 6 and clean air is silenced by the water tank of the silencer 6. As shown in FIG.
After the collection operation is completed, the suction vehicle is moved to the disposal site and the collected material in the hopper 4 is discarded.

After the suction operation is finished, the collected matter collected and sucked into the hopper 4 is discarded. However, since fine dust is also collected in the silencing water tank 6, not only inside the hopper 4 but also fine dust in the silencing water tank 6 is included. Sewage needs to be discarded.
This is because the silencing water tank 6 contains a large amount of water in order to prevent the fine dust from being released to the outside air, but it becomes sewage containing fine dust as the suction operation proceeds.
This discarding operation adds the collected material sucked and collected in the hopper 4 to the disposal, which takes time and effort.
In particular, since the volume for storing sewage containing the collected material is smaller than the hopper 4, it is sometimes necessary to dispose of it in a separate tank provided at the collection site.

  The purpose of the present invention is to collect sludge and other sludge recovery equipment and sludge that can smoothly collect industrial waste in a fluid state consisting of collected matter in the hopper and sewage containing fine dust in the silencing water tank and increase the efficiency of the disposal work.
