Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a circulating wastewater treatment device. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production. In order to avoid environmental pollution from the various precipitated particulate matter contained in industrial wastewater, it is necessary to treat the wastewater through a circulating industrial wastewater treatment device before it can be discharged. The treatment process usually involves passing industrial wastewater into the device for filtration, filtering out particulate matter of different sizes and volumes, separating the particulate matter from the wastewater, and then adding a small amount of material to react with the wastewater to achieve purification.

[0003] Currently, most existing wastewater treatment equipment in the industry is an integrated structure, directly installed on the sewage pipe. This integrated wastewater treatment equipment intercepts floating particulate matter in the flowing sewage, thus achieving separation and filtration. However, due to its integrated structure, particulate matter accumulates inside the wastewater treatment equipment during the filtration process, making it difficult to remove the filtered particulate matter during subsequent cleaning and maintenance. Therefore, a circulating wastewater treatment device is needed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a circulating sewage treatment device to solve the problem that most existing sewage treatment equipment in the industry is an integrated structure that is directly installed on sewage pipes. The integrated sewage treatment equipment intercepts floating particulate matter in the sewage flowing in the pipes, thereby playing a separation and filtration role. However, in actual use, due to its integrated structure, the existing integrated sewage treatment equipment has the technical problem that particulate matter accumulates inside the sewage treatment equipment during the filtration process, making it difficult to remove the filtered particulate matter during subsequent cleaning and maintenance.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A circulating sewage treatment device includes a vane pump and a servo motor that drives the vane pump to rotate. One end of the vane pump is provided with an outlet, and the other end of the vane pump is provided with a sewage filter. The other end of the sewage filter is connected to a pumping pipe for pumping sewage from a sewage tank. The sewage filter is provided with a washable filter screen that can be recycled and replaced.

[0007] As a preferred technical solution of this utility model, the sewage filter has a filter chamber on its side, the cross-section of the filter chamber is a square hole structure, the left and right ends of the filter chamber are connected through the water pump and the vane pump, and the inner wall of the filter chamber is provided with a number of guide grooves at equal intervals.

[0008] As a preferred embodiment of this utility model, the outer wall of the sewage filter is equipped with a cover plate, and threaded holes are opened on both sides of the filter cavity on the outer wall of the sewage filter.

[0009] As a preferred embodiment of this utility model, a number of locking screws are symmetrically installed on the left and right sides of the cover plate, and each locking screw is locked and fixed in the corresponding threaded hole on the surface of the sewage filter.

[0010] As a preferred technical solution of this utility model, a number of washable filter screens are fixed on the surface of the cover plate, and adjacent washable filter screens are arranged in parallel with equal spacing. Each washable filter screen is inserted into a corresponding guide groove on the inner wall of the filter chamber.

[0011] As a preferred technical solution of this utility model, the mesh sizes of the multiple washable filter screens are different, and the mesh sizes of adjacent washable filter screens decrease from the direction of water flow in the filtration chamber to the direction of water flow out.

[0012] As a preferred embodiment of this utility model, the surface of the cover plate is provided with a plurality of thickening textures, which are wavy.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a vane pump and a servo motor to drive the vane pump. One end of the vane pump has an outlet, and the other end has a wastewater filter. The other end of the wastewater filter is connected to a pumping pipe for drawing wastewater from a wastewater tank. The wastewater filter performs multi-stage filtration on the drawn wastewater, effectively improving the quality of the discharged water. The wastewater filter contains a reusable, washable filter screen. This removable design facilitates cleaning and maintenance, and the cleaned filter screen can be reused, effectively reducing consumables in the wastewater treatment process.

[0015] This utility model of a sewage filter has a filter chamber on its side. The filter chamber has a square hole structure in its cross-section, which facilitates the placement of a washable filter screen. The left and right ends of the filter chamber are connected through the water pump and the vane pump. The inner wall of the filter chamber has several guide grooves at equal intervals. These grooves facilitate the placement of the washable filter screen and also serve to position and guide the installation, improving the installation effect.

[0016] The wastewater filter has a cover plate installed on its outer wall. Threaded holes are provided on both sides of the filter chamber on the outer wall of the wastewater filter to facilitate installation and removal of the cover plate. Several locking screws are symmetrically installed on both sides of the cover plate. Each locking screw is locked into the corresponding threaded hole on the surface of the wastewater filter, improving the tightness of the cover plate installation and effectively preventing the cover plate from peeling off from the wastewater filter due to excessive water pressure. The design of the locking screws and threaded holes effectively improves the ease of operation during disassembly and enhances the connection stability between the cover plate and the wastewater filter.

[0017] Several washable filter screens are fixed on the surface of the cover plate. The washable filter screens are arranged in parallel with equal spacing between adjacent ones. Each washable filter screen is inserted into the corresponding guide groove on the inner wall of the filter chamber, which improves the installation position of adjacent washable filter screens and enables the washable filter screens to maintain a fixed interval distance during use.

[0018] The multiple washable filter screens have varying mesh sizes, arranged from inflow to outflow within the filtration chamber. The mesh size decreases between adjacent screens, enabling tiered filtration. The screens are made of finely woven steel wire, and each stage effectively filters out larger particles floating in the wastewater. This multi-stage filtration separates particulate matter from the wastewater, which is then pumped out via a vane pump. The cover plate has several wavy, reinforced grooves on its surface to enhance structural strength.
