2. Description of the Related Art Conventionally, there is known a sewage cleaning apparatus in which sediment such as sludge deposited in a sewage system is sucked into a tank together with moisture, and then the sediment and moisture are separated. See JP-A-63-236830).

[0003]

However, in such an apparatus, since deposits such as sludge are stored in a closed tank by suction, the tank may be inclined to discharge the deposits to the outside. However, it is difficult to discharge without leaving it, and there is a bad effect that the discharge adheres and accumulates on the inner wall of the tank to reduce the storage capacity of the tank. Then, this cleaning depended on manual labor.

[0004] However, this cleaning work is extremely troublesome, and it is not only difficult to secure human resources, but also the work efficiency is poor and the cost is increased.

The present invention has been made in view of the above circumstances, and sucks an external fluid such as sludge water into a high-pressure tank, separates it into solid matter and moisture, and uses the water to make a sewerage system. It is an object of the present invention to provide a novel cleaning and suction vehicle that enables drain pipes and the like to be cleaned neatly and efficiently and that the inner and outer surfaces of the tank can be cleaned neatly by fresh water.

[0032] Cleaning action in the pressure tank (FIG. 8) This is an action of cleaning the pressure tank Tp with fresh water, and the partitioning wall 18 is rotated about 90 ° from the closed position by the extension operation of the open / close cylinder 23 to the substantially horizontal open position. Hold. After the second recycle valve 61 is closed, the first recycle valve 60 and the third opening / closing valve 59 are opened, and the water pump P is driven, the fresh water stored in the fresh water tank Tw in advance becomes the arrow in FIG. As shown in i, the water is sucked into the water pump P through the third branch pipe 55 and the water suction pipe 45, and the pressurized water therefrom is supplied to the high pressure water pipe 46, the branch joint 47, and the cleaning circuit in the tank as shown by the arrow j in FIG. The gas is ejected from the ejection nozzle 50 into the pressure tank Tp through 49, and the inside of the pressure tank Tp can be cleaned.

[0033] Cleaning action outside the tank (FIG. 9) This is an action of cleaning the outside of the tank, such as the outer surface of the tank assembly T and its surroundings, with fresh water in the fresh water tank Tw, by closing the open / close valve 52 from the state of FIG. By switching 51 to open, high-pressure water can be supplied from the high-pressure water pipe 46, the branch joint 47, and another external cleaning circuit 48 to the cleaning gun 16 through the hose 15 as shown by the arrow k in FIG. By pulling out the hose from the hose reel 12, the outer surfaces of the pressure tank Tp and other devices can be washed with pressure washing water.

In the above embodiment, the case where the sludge water in the sewerage or the like is sucked into the pressure tank has been described, but it is needless to say that other external fluids may be sucked.

The pressure tank and the fresh water tank can be used in various other ways. For example, the partition walls may be opened and the first and second chambers of the pressure tank may be used as sludge water storage tanks. The first chamber of the fresh water tank and the first chamber of the pressure tank may be used as the fresh water tank. Both the first and second chambers of the tank and the pressure tank may be fresh water tanks.
