Full-automatic cleaning equipment applied to urban sewage treatment

Abstract

The invention discloses full-automatic cleaning equipment applied to urban sewage treatment, wherein the full-automatic cleaning equipment structurally comprises a base, a working box, a top plate, a conveying pipe and a control panel; the upper end of the base is connected to the lower end of the working box through a stud, the upper end of the working box is connected to the lower end of the top plate through a bolt, and the left end of the conveying pipe is welded to the right end of the working box; the rear end of the control panel is fixedly connected to the front end of the working box in an embedded mode; the equipment is powered on, sewage flows into the conveying pipe and enters the working box, the control panel is operated, a driving wheel rotates, and the driving wheel drives a connecting plate at the front end of a pressing plate; a scraping corner abuts against a guide strip at the left end of a connecting block for supporting, and a clamping strip abuts against the inner side of a clamping ring; the connecting block is tightly attached to a pressing frame on the inner side of a fixing block to be fixed, an abutting column pushes an abutting plate, the abutting plate extrudes an elastic column to contract, after a hard block solid is scraped, the scraping corner rebounds to shake off the hard block solid, and the situation that the hard block solid is clamped on the filter screen under the impact of sewage, consequently, the hard block solid is accumulated on the filter screen, and the sewage filtering amount is reduced is prevented.

Description

technical field [0001] The invention belongs to the technical field of urban sewage treatment and resource utilization, and in particular relates to a fully automatic cleaning device applied to urban sewage treatment. Background technique [0002] Urban sewage refers to the domestic sewage and some industrial wastewater produced by urban residents. After the food oil in the domestic wastewater is mixed with the chemicals in the industrial wastewater, there will be a material reaction to form foul-smelling mixed sewage and deposited hard objects. After filtering through the filter in the automatic cleaning device, it is recovered. [0003] Based on the above description, the inventors found that the existing fully automatic cleaning equipment for urban sewage treatment mainly has the following deficiencies, for example: in the rainy season, mixed sewage and rainwater are combined to increase the flow pressure of sewage, The hard objects are driven by the water flow to the fi...

[0003] Based on the above description, the inventors found that the existing fully automatic cleaning equipment for urban sewage treatment mainly has the following deficiencies, for example: in the rainy season, mixed sewage and rainwater are combined to increase the flow pressure of sewage, The hard objects are driven by the water flow to the filter screen to be squeezed. After the hard objects are filtered by the filter screen, under the continuous pressure of the sewage, the hard objects are stuck on the filter screen, causing the filter screen to be accumulated by the hard objects, resulting in the filtration of clean and recycled sewage. Flow becomes smaller
