Drainage combined with sludge-cleaning vehicle sludge-water separating system

Abstract

A sludge-water separation system for a combined sewer sludge-cleaning vehicle comprises a rotary filter cylinder (8), a bracket (5), a buoy (10), a sewage pump, a hydraulic motor (13), a high-pressure backwashing water pipe (6), a sludge discharge valve (12), as well as connecting pipes and valves; wherein, the rotary filter cylinder and the sewage pump adopt hydraulic drive. During operation, the slurry sucked into a sludge tank is filtered through the sieve of the rotary filter cylinder, then pumped out of the tank body through the sewage pump, and finally discharged into the sewer. Therefore, the sludge tank can continue suck sludge and sewage. The hydraulic motor drives the rotary filter cylinder to endlessly rotate to prevent the sieve of the filter cylinder being jammed by the dirt in the sludge tank. The high-pressure backwashing water pipe effectively ensures the smooth screening of the sieve and can thoroughly wash the rotary filter cylinder after the completion of the sludge-cleaning operation so as to reduce the corrosion of the system caused by the slurry and make sure the operation can go on smoothly. The remaining viscous sludge in the tank body is discharged out of the vehicle through a sludge discharge valve, then collected or naturally dried and finally carried to refuse sites.

Description

technical field [0001] The invention relates to a vehicle-mounted mud-water separation system, in particular to the mud-water separation system for a sewer united sewage cleaning vehicle. Background technique [0002] With the rapid development of modern urban construction, the length of urban sewers is also increasing rapidly, and the dredging work of sewers is becoming more and more arduous. Because the manual dredging of urban sewers is slow and very difficult, and sometimes even has the risk of casualties, the mechanization of urban sewer dredging will become inevitable. As one of the sanitation vehicles, the sewer cleaning vehicle has the functions of flushing the sewer, suctioning sludge, realizing timely dredging of the sewer, purifying the air, and beautifying the environment. It is an important equipment for urban environmental protection and construction. It is generally believed that the sewer cleaning vehicle refers to the function of flushing the sewer or sucti...

Problems solved by technology

[0009]3. The sewage circulation system requires a relatively long settling time because it has to go through several stages of filtration; the structure of the other stages of filter chambers will also be more complicated and difficult to manufacture The cost and cost are very high and it is difficult to achieve long-term reliable work; although it has undergone several stages of physical filtration, the filtered water still contains many particles and chemical substances, which will cause the high-pressure water pump with high water quality requirements to be corroded to a certain extent. shortened its life
