A rotary sewage pretreatment device based on centrifugal force

Abstract

The invention provides a centrifugal force based rotary sewage pre-treatment device, and relates to the technical field of water pollution treatment. The centrifugal force based rotary sewage pre-treatment device includes a tank, wherein the bottom of the tank is fixedly provided with a support; a filtering device is fixedly installed in the tank; a potion bottle is in threaded connection with the top of the tank; a current-limiting rod is in sliding connection onto a position below the potion bottle on the top of the tank; leaking holes are formed below the current-limiting rod at the top of the tank; two swirling device are fixedly connected with two sides of the tank. According to the centrifugal force based rotary sewage pre-treatment device provided by the invention, centrifugal force is adopted to collect and clean impurities; repetitive work can be performed; no cleaning is needed; labor conservation and effectiveness are realized; inertia of the sewage itself is adopted to replace traditional stirring devices, the device is not easy to damage and energy is saved; a certain number of adhesive is automatically added into the tank, so that waste of adhesive is avoided.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a rotary sewage pretreatment device based on centrifugal force. Background technique [0002] With the development of science and technology, the problem of environmental pollution is becoming more and more serious. Among them, sewage treatment is the most important of many environmental problems. Sewage includes industrial sewage and domestic sewage. If the sewage cannot be completely purified, it will be discharged directly and will re-enter the earth. In the water circulation system of the environment, while destroying the ecological environment, sewage will also enter the human body and affect human health. [0003] In the process of sewage treatment, it is necessary to pretreat the sewage first, so as to clean up the solid and flocculent impurities in the sewage, while the traditional sewage pretreatment device uses a filter plate to isolate and clean the i...

Problems solved by technology

[0003] In the process of sewage treatment, it is necessary to pretreat the sewage first, so as to clean up the solid and flocculent impurities in the sewage, while the traditional sewage pretreatment device uses a filter plate to isolate and clean the impurities. Impurities will adhere to the filter plate afterwards, and regular cleaning is required, and the cleaning effect will be reduced after long-term use, and traditional sewage treatment devices use motors to drive paddles to stir sewage, which takes a lot of time A lot of power, and easy to damage requires regular maintenance
