Description

TECHNICAL FIELD

[0001] The present application relates to a kind of quick sealing sewage device, belongs to the technical field of sewage suction truck. BACKGROUND

[0002] Sewage suction truck is a kind of sanitation vehicle for transferring, cleaning and transporting sewage, sludge and wastewater to avoid secondary pollution. The working principle is that the air in the tank is continuously discharged under the action of vacuum pump, the suction hose is always immersed in the sewage pool, and the air pressure in the tank is lower and lower. Sewage, manure and other liquids are sucked into the tank under the action of atmospheric pressure. At present, sewage suction truck is widely used in municipal sewage cleaning and wastewater treatment of large enterprises.

[0003] Up to now, many units and individuals have improved the structure of traditional screening machines. For example, the patent number CN201510321821.X discloses a vacuum sewage suction vehicle, which comprises a vehicle body, a sewage tank fixed on the vehicle body, a deodorization chamber arranged at the upper end of the sewage tank, a suction port for connecting the deodorization chamber and the inner chamber of the sewage tank, a gas pressure balance port provided on the top of the sewage tank, a deodorization filter screen installed on the gas pressure balance port, a vacuum pump installed on the outside of the sewage tank, and a suction inlet of the vacuum pump connected with the sewage cleaning device. The deodorization chamber is arranged in the sewage tank, and the suction port is automatically opened when the vacuum pump is working. The deodorization chamber and the deodorization filter screen can effectively absorb and filter odors, and also have the function of water flushing, which is more sanitary and environmentally friendly.

[0004] For another example, the patent number CN201320160932.3 discloses a vacuum sewage tank and a sewage suction vehicle. The vacuum sewage tank comprises a tank body for storing sewage and an inlet and a suction port arranged horizontally on the tank body. The tank body comprises a plurality of containing chambers connected in sequence in the horizontal direction, and the inlet and the suction port are located in different containing chambers. The sewage suction vehicle uses the vacuum sewage tank provided by the present application. Since the suction port and the inlet are not located in the same containing chamber, the foam generated in the chamber where the inlet is located can be effectively filtered when entering the chamber where the suction port is located, thereby reducing the influence of foam on the vacuum pump system, and the structure is simple and practical.
