Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically relates to a sewage purification device. Background Art

[0002] Application No. 202321153618.2 provides a sewage sedimentation purification device. Through the setting of the collection unit, the sewage enters the collection unit after passing through the cutting unit, and enters the stirring unit through the filter net for subsequent treatment. The larger solid impurities in the sewage are cut and fall on the filter net, and the solid impurities cannot pass through the filter net. When the precipitated impurities on the filter net accumulate too much, the drive motor is started to drive the deformation column to move up and down, and then drive the striking frame to strike the upper and lower load-bearing frames, so that the precipitated impurities on the filter net are dispersed, and one side of the device can be opened to take out the load-bearing frame, pour out the precipitated impurities and put it back for reuse;

[0003] However, there are some problems with the device when it is used: first, the precipitated impurities on the filter screen are dispersed by hitting the upper and lower load-bearing frames through the striking frame, but the amount of precipitated impurities does not change, resulting in the fact that the impact of the impurities on the filter screen does not actually decrease. As the feed increases, even if the striking frame hits the load-bearing frame, it will cause material discharge blockage; secondly, the frequent hitting of the striking frame on the load-bearing frame will reduce the service life of the load-bearing frame, requiring frequent replacement, and having poor practicality.
