Primary purified water treatment tank

Abstract

The invention discloses a primary purified water treatment tank which mainly comprises a purification tank, a fixed filtering plate, a movable filtering plate, a power device and a connecting rod, wherein a water inlet is formed in one end of the upper part of the purification tank; a purified water outlet is formed in the other end of the upper part of the purification tank; a first drain outlet is formed in one end of the lower part of the purification tank; a second drain outlet is formed in the other end of the lower part of the purification tank; the fixed filtering plate and the movable filtering plate are arranged in parallel to isolate the water inlet from the water outlet; the movable filtering plate is connected with the power device through the connecting rod so as to move to approach to the upper water inlet and the lower first drain outlet, and can be automatically washed through high-level falling water at regular time. According to the primary purified water treatment tank, small holes for filtering sewage are formed when filtering holes in two filtering plates inside the tank body are overlapped and covered by each other, after the two plates are separated, large holes are easy to clean, the movable filtering plate can be moved to a space between the upper water inlet and the lower first drain outlet at regular time, and the filtering holes can be automatically washed through high-level falling water, so that the washing can be continuously performed at regular time, and the advantages of no blocking and load resistance are achieved.

Description

technical field [0001] The invention relates to sewage purification treatment equipment, in particular to a non-clogging self-cleaning filter for treating sewage with multiple suspended matter. Background technique [0002] In some treatment occasions containing high-suspended solids sewage, conventional treatment equipment cannot operate continuously and stably due to high suspended solids content, blockage, fouling and other failures, making it necessary to establish a large area of ​​sedimentation to treat this type of sewage pool, and it will also cause difficulties such as sludge discharge due to the high content of impurities such as sludge. In today's increasingly tense land resources, the cost of dealing with this type of wastewater is very high. The preliminary cleaning and filtration process of sewage treatment is very important. The filter screen of the device is constantly blocked, and it takes a lot of time and equipment to replace and clean it continuously. ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the clogging and cleaning problem of the filter screen in the preliminary filtration process of sewage treatment, I developed a preliminary treatment tank for purified water. This preliminary treatment tank does not need to be opened to replace the cleaning filter screen, and it can automatically clean the filter screen.
