Sewage full-automatic sewage-removing machine

Abstract

The invention relates to a full automatic pollutant remover of sewage, which is used in sewage filtrating process of sewage source heat pump system. The invention is mainly composed of a cylinder shaped filter screen, a pollutant removal scraper, a shaft, a pollutant removal machine casing, a sewage segregator, an upper cover board, a lower cover board, a separator and so on. The pollutant removal scraper can rotate, which can ensure that no pollutant sundries dead angle can be found, and ensure to scrape off fiber typed pollutant sundries like the animal hair and so on. The sewage segregator is arranged to match the rotating of the pollutant removal scraper, in order to realize the impurity contained sewage feed water inside the cylinder filter screen. After being removed pollutant, the water is fed from outside of the cylinder. After being exchanged heat, the sewage backs into cylinder filter screen. After being backwashed, the impurity contained sewage is drained out of the cylinder filter screen. On working process, the invention needs no manual work to remove the pollutant every a fixed period, which can realize full automatic pollutant remove function.

Description

technical field [0001] The invention relates to a sewage decontamination device, in particular to a fully automatic decontamination machine for filtering sewage impurities in a primary sewage source heat pump system. Background technique [0002] With the rapid promotion of water source heat pump technology in my country, the primary sewage source heat pump technology has also been developed and applied to a certain extent. This technology obtains heat from urban raw sewage in winter and releases heat in summer, utilizing renewable energy and realizing a circular economy. The biggest problem in using urban raw sewage as the cold and heat source of heat pump air-conditioning units is how to prevent pollution and blockage of pipelines and heat exchange equipment by sewage containing impurities. The patent application number is: 200410043654.9. The invention patent provides a decontamination device that blocks impurities in sewage. The device is composed of a shell, a cylindri...
