The pipe network circulation desanding device for sewage treatment as claimed in claim 1, wherein: the spraying sand removing mechanism (7) comprises a sealing plate (701), a spraying seat (702) is arranged on the outer side of the sealing plate (701), and a water filling port (703) is arranged in the center of the outer side of the spraying seat (702);
and a first blanking hole and a second blanking hole which correspond to the first collecting groove (8) and the second collecting groove (9) are respectively formed in two sides of the bottom of the sand removing device main body (2).
9. The pipe network circulation desanding device for sewage treatment as claimed in claim 1, wherein: the automatic control system is used for controlling the automatic cleaning of the silt filtering mechanism (3), and comprises a first water pressure sensor (10) and a second water pressure sensor (11) which are respectively and correspondingly arranged on the water inlet side and the water outlet side of the sewage drainage network pipe (1); first water pressure sensor (10) and second water pressure sensor (11) link to each other with the signal input part of controller, the signal output part of controller links to each other with actuating mechanism (4) and spray sand removal mechanism (7) to when guaranteeing that the water pressure differential value of first water pressure sensor (10) and second water pressure sensor (11) reaches the setting value, automatic control actuating mechanism (4) and spray sand removal mechanism (7) action realize the automatic switch-over and the washing of silt filtering mechanism (3).
10. The operation method of the pipe network circulation desanding device for sewage treatment as claimed in any one of claims 1 to 9, characterized by comprising the following steps:
step one, butt joint installation of a sand removing device main body (2): in a specific using process, firstly, the sewage draining network pipe (1) is butted with the desanding device main body (2);
Step two: and (3) filtering sewage: in the sewage discharging process, sewage enters the silt filtering mechanism (3) of the desanding device main body (2) from the sewage discharging network pipe (1), and the silt with different sizes in the sewage discharging network pipe (1) is subjected to graded filtering through graded filtering nets (302) with different apertures on the silt filtering mechanism (3), so that good sand removing and anti-blocking effects are achieved;
step three: switching of the silt filtering mechanism (3): after the graded filter screen (302) at one side of the silt filter mechanism (3) filters the sewage for a period of time, certain blockage can be generated, at the moment, the first water pressure sensor (10) and the second water pressure sensor (11) transmit differential pressure signals at two sides of the sediment filtering mechanism (3) to the controller, when the differential pressure between the first water pressure sensor and the second water pressure sensor exceeds a set value, the silt filtering mechanism (3) is blocked and needs to be cleaned, at the moment, the controller starts the driving mechanism (4), the bidirectional cylinder (402) bidirectionally pushes the guide mechanism (5) to reciprocate through the bidirectional piston rod (403) and the two fixed blocks (404), and then the silt filtering mechanism (3) is driven to move in the main body (2) of the desanding device by the guide mechanism (5), then the silt filtering mechanism (3) is switched, and one side to be cleaned is sent to the side where the spraying and sand removing mechanism (7) is located;
Step four: cleaning a sediment filtering mechanism (3): after the sediment filtering mechanism (3) moves in place, the controller controls the spraying and sand removing mechanism (7) to be started, the water injection port (703) is connected with a high-pressure water source, then the sediment filtering mechanism (3) is washed at high pressure through a plurality of nozzles which are arranged on the upper inner side of the spraying seat (702), and the intermediate partition plate (303) intercepts the sediment in the washing process and collects the first collecting groove (8) and the second collecting groove (9) on the corresponding side.
