Sewage full-automatic sewage-removing machine

Abstract

A sewage automatic decontamination machine, used in the sewage filtration process of the sewage source heat pump system, mainly consists of a cylindrical filter screen, a decontamination scraper, a shaft, a decontamination machine shell, a sewage water separator, an upper cover, a lower Cover, partition and other components. The rotatable decontamination scraper is provided to ensure that there is no dead angle of accumulation of dirt and debris, and to scrape off the fibrous dirt such as animal hair on the filter screen. There is also a sewage water separator, which cooperates with the rotation of the decontamination scraper to realize the supply of impurity-containing sewage inside the cylindrical filter, the sewage after decontamination is supplied from the outside of the cylinder, and the sewage after heat exchange is returned from the outside of the cylindrical filter. After backwashing, the impurity-containing sewage is discharged from the cylindrical filter screen. The device of the invention does not need to manually open the device regularly to remove dirt during the working process, and realizes the function of automatic decontamination.

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...
