Sewage circulating system

Abstract

The invention provides a sewage circulating system. The sewage circulating system comprises a sludge tank, a clean water tank, a high pressure pump, a pump, a valve, a nozzle, a reel and a hose, wherein a rotating filter drum, a support, a partition plate, a cylinder, a filter drum base, a flushing pipe, a connecting shaft, a hinge, an oil motor, an oil motor support and a sewage suction pipe are arranged in the sludge tank; the partition plate comprises a fixed partition plate and a turnover partition plate; the support comprises a first support and a second support; an access door is arranged on the fixed partition plate; a first clearance is formed between the turnover partition plate and the inner wall of the sludge tank; a second clearance and a third clearance are formed between the fixed partition plate and the inner wall of the sludge tank; the first clearance is less than the second clearance; and the second clearance is less than the third clearance. The sewage circulating system disclosed by the invention has the advantages of simple structure and convenience for manufacturing; and as the system adopts secondary filtering, the filtering link is reduced and the reliability of the system is higher. In addition, the requirement of the system on the impurity content of final filtered water is far lower than that of a common sewage circulating system on the market; and the system can also normally work when the filtering accuracy is 500 microns.

Description

technical field [0001] The invention relates to a vehicle-mounted mud-water separation system, in particular to a sewage circulation system. Background technique [0002] With the development of industry, industrial water consumption increases rapidly, and water resources become increasingly scarce. While developing water resources, it is of great significance to improve the utilization rate of water recycling to save water. 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 difficult, and sometimes there is a danger 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 th...
