Constructional industrial sewage pretreatment device

Abstract

The invention discloses a constructional industrial sewage pretreatment device. The device comprises a sewage treatment tank, the right side of the sewage treatment tank is fixedly connected with a motor box, the bottom of the inner cavity of the motor box is fixedly connected with a motor through a mounting member, a cleaning mechanism is arranged in the inner cavity of the sewage treatment tank,the output shaft of the motor is fixedly connected with the cleaning mechanism, and two sides of the sewage treatment tank are fixedly connected with collecting mechanisms. The motor drives the cleaning mechanism to move leftwards and rightwards in order to push solid matters on the surface of a filter screen into the collecting mechanisms, so the effect of automatically removing the solid matters in the constructional industrial sewage is achieved; and pull plates at both sides of the sewage treatment tank are pulled by a user to take out silt filtration mechanism or an active carbon adsorption mechanism in order to achieve the effect of easily dismounting a filter plate rack, so the constructional industrial sewage pretreatment device has the advantages of time saving, labor saving, andconvenience in maintenance.

Description

technical field [0001] The invention relates to the technical field of construction industry, in particular to a sewage pretreatment device for construction industry. Background technique [0002] Construction industrial sewage is characterized by high content of minerals and suspended solids, and generally has no great toxicity. The main hazard is heavy metal pollution to the environment, which will cause sudden excessive metal content in soil and water, and promote the odor of soil or bottom-deposited substances. , worsen soil and water quality, and pollute the environment. [0003] The construction industry has a wide range of raw materials, and there are many types of them. The amount and quality of the sewage discharged are quite different. The main pollutants in the sewage include solid substances, such as iron, copper, and various ores, etc., as well as sand and stone suspended in the sewage. Grease and colloidal substances, etc., the traditional construction industr...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a construction industry sewage pretreatment device, which has the advantages of saving time and effort and convenient maintenance, and solves the problem that the traditional construction industry sewage pretreatment is first to filter solid matter through a screen, and the residual solid matter needs to be Manual cleaning is time-consuming and laborious, and the filter plate frame for filtering grease, sediment and other substances cannot be disassembled, and the later cleaning and replacement are cumbersome.
