本発明は汚泥収容タンク内に汚泥を吸引すると
ともに汚泥収容タンク内に収容した汚泥を圧送で
きるようにした汚泥車における汚泥吸排制御装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sludge suction and discharge control device for a sludge truck, which is capable of sucking sludge into a sludge storage tank and pumping the sludge stored in the sludge storage tank.

ク内を加圧すると同時に汚泥吸引管も加圧するこ
とにより、汚泥吸引管の閉塞を解除している。 Generally, in a sludge truck, sludge is sucked into the tank through a sludge suction pipe by the vacuum pressure inside the tank. Since pebbles and the like may be sucked up along with the sludge during sludge suction, the sludge suction pipe may sometimes be blocked by the pebbles. As a method to release this blockage, the inside of the tank is pressurized through the pressure line from the vacuum pump that pumps the sludge contained in the tank, and the sludge suction pipe is also pressurized at the same time, thereby releasing the blockage of the sludge suction pipe. There is.

され、非常に危険となる。 However, in the conventional method described above, the sludge storage tank is also pressurized in addition to the sludge suction pipe, so when the sludge suction pipe is unblocked, a large amount of air in the pressurized tank is released into the atmosphere through the sludge suction pipe. As a result, the pebbles in the sludge suction pipe are violently blown away, which is extremely dangerous.

となる。 The present invention has the above-described configuration, and to explain the case where sludge is stored in the sludge storage tank 1, first, the first three-way cock 13 is operated to connect the suction and discharge pipes 18 and the first
The suction part 20 is connected to the suction part 20, and the second three-way cock 23 is operated to connect the second pressurizing pipe 27 and the atmospheric pipe 29.
When the vacuum pump 12 is driven, the air in the tank 1 is released into the atmosphere through the suction/discharge pipe 18, the first suction section 20, the second pressurizing pipe 27, and the atmospheric pipe 29. There will be a vacuum inside.

In this case, in order to remove the pebbles, the second three-way pot 23 is operated from the above state to remove the atmospheric pipe 29 and the second suction pipe 28.
When the first port 24 of the second three-way cock 23 is closed, the second on-off valve 32 is closed, and the first on-off valve 31 is opened, the air in the atmosphere flows through the atmospheric pipe 29 and the second port 23. Suction pipe 28, third discharge pipe 3
0 into the sludge suction pipe 10,
This pressurized air allows the pebbles sucked into the sludge suction pipe 10 to be taken out.

所に圧送されてることになる。 Next, there are two methods for discharging the sludge stored in the sludge storage tank 1: a method of discharging it by its own weight, and a method of pumping it by air pressure.When discharging by its own weight, the lid body 4 is opened and the tank body 3 is dumped. Then, the sludge in the tank body 3 will be dumped and discharged. On the other hand, in the case of pressure feeding using air pressure, the first three-way cock 13 is operated to connect the suction/discharge pipe 18 and the first pressurizing pipe 22, and then the second
When the three-way cock 23 is operated to connect the atmosphere 29 and the second suction pipe 28, the air in the atmosphere passes through the atmosphere pipe 29, the second suction pipe 28, the first pressurizing pipe 22, and the suction/exhaust pipe 18 to the tank. Since the sludge is press-fitted into the tank 1, the pressurized air in the tank 1 forces the sludge in the tank 1 through the discharge pipe 11 to a desired location.

て閉塞の解除作業を行うことができる。 As described above, the present invention introduces the air discharged from the discharge part of the vacuum pump into the tank through the suction/discharge part in the upper part of the tank, and pressurizes the inside of the tank with this air. In addition, the air discharged from the vacuum pump is guided to the middle of the sludge suction pipe, and this air pressurizes only the inside of the sludge suction pipe to remove small stones stuck in the middle of the sludge suction pipe. Since the pebbles are removed, the amount of air discharged together with the pebbles is small, making it possible to safely clear the blockage.
