Automatic decontamination filter grid

Abstract

The invention discloses an automatic decontamination filter grid comprising a filtering surface, wherein the filtering surface is installed at a water collecting head position of a water guiding pipe,the filtering surface is provided with a plurality of filtering holes, two decontamination devices are symmetrically disposed before the filtering surface, each decontamination device includes a first fixing seat, a first connecting block is disposed on the top side of the first fixing base, and a cross bar is disposed on one side of the first connecting block . Beneficial effects are that: the automatic decontamination filter grid has the advantages of reasonable design, simple structure, low engineering cost and low cost of use and maintenance, and effectively solves the clogging phenomenonof a water taking initial effect grid in an original sewage source heat pump system so as to effectively improve the initial filtration ability and effectively reduce the decontamination pressure ofdownstream equipment; automatic decontamination is achieved, the frequency of manual maintenance is reduced, and the operational reliability of the entire subsystem is improved, so that the automaticdecontamination filter grid is more suitable for a wide range of application.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to an automatic decontamination filter grid. Background technique [0002] At present, in the raw sewage source heat pump system and project, the sewage subsystem is the key to the success of the project. Due to the complex water quality of the raw sewage, which is rich in suspended sewage, it is easy to cause blockage of the heat exchange equipment. Therefore, in The extraction and treatment of sewage in engineering applications has become an unavoidable technical problem in sewage source heat pump projects. [0003] The technical method commonly used in engineering is to draw water horizontally from the main sewage canal, interrupt the main canal, build a water intake square culvert, and draw water in the square culvert. Set the primary filter grille at the water intake head of the water diversion pipeline to filter out large-scale debris in the sewage. Then let...
