Sand setting device for sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, in particular to a sand setting device for sewage treatment. The sand setting device comprises a sand setting box body and a motor, wherein the top end of the sand setting box body is provided with a water inlet, the bottom end of the sand setting box body is provided with a sand discharging box body, the lower side of the sand discharging box body is provided with a sand discharging port, the top end of the sand setting box body is fixedly provided with the motor, the output end of the motor is fixedly connected with a rotatingshaft, the outer side of the rotating shaft is fixedly connected with stirring blades, the lower side of the rotating shaft is fixedly sleeved with a rotating plate, the right side of the rotating plate is fixedly connected with a handle, and an operation window is formed in the position, corresponding to the handle, of the inner wall of the sand setting box body. The sand setting device is provided with the rotating plate and conveying rollers, sewage is conveyed to the bottom end of the sand setting box body at a constant speed, quantitative conveying of the sewage is achieved, sand grainsat the bottom end of the sand setting box body are conveyed to the exterior of the device, and the working efficiency of the sand setting device in use is improved; and primary filtering of to-be-treated sewage is achieved through a filter screen and a fixed shaft.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sand settling device for sewage treatment. Background technique [0002] During the process of migration, flow and collection, sewage will inevitably be mixed with mud and sand. If the sand in the sewage is not separated and removed in advance, it will affect the operation of the subsequent treatment equipment, which will cause abrasion of the machine pump, blockage of the pipe network, interference or even Destroying the biochemical treatment process, the existing sand settling device is not ideal for mud and sand treatment efficiency, takes a long time, is inconvenient to use, and affects the work efficiency of users. Therefore, we propose a sand settling device for sewage treatment device to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a sand settling device for sewage treatment to solve the proble...
