Water inlet device of buried sewage treatment system

Abstract

The invention relates to the technical field of sewage treatment, and discloses a water inlet device of a buried sewage treatment system. A water inlet groove is fixedly formed in the top end of the upper portion of a body, a steel pipe is movably connected to the lower end of the water inlet groove, a mounting base is movably connected to the bottom end of the steel pipe, and a fastener is movably installed in the mounting base. According to the water inlet device of the buried sewage treatment system, sewage is added into the body from the water inlet groove, the sewage moves downwards into the mounting base along the steel pipe and forms certain flow velocity force, the mounting base deflects left and right under the action of the flow velocity force, a rotary disc in the mounting base rotates to generate centrifugal force, teeth on the rotary disc are meshed with teeth on a telescopic part, the telescopic part expands outwards under the action of the centrifugal force and gravity, and therefore the impact amount of the sewage passing through the interior is controlled, the purpose of controlling the flow and water pressure is achieved, the water pressure is reduced, and the situation that a water inlet gate is damaged due to the too large water pressure difference is prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water inlet device of an underground sewage treatment system. Background technique [0002] The buried sewage treatment equipment is a modular high-efficiency sewage biological treatment equipment. It is a sewage biological treatment system with biofilm as the main body of purification. It has the characteristics of high biological density, strong pollution resistance, low power consumption, stable operation and convenient maintenance. It is mainly a device or measure to bury the water inlet device in the sewage treatment system underground by using a large amount of underground space. . [0003] In recent years, with the warming of the global climate and the frequent occurrence of extreme weather such as heavy rains, it is very easy to cause the urban water level to rise sharply in a short period of time, resulting in a large increase in the water pressure of the sew...
