Self-cleaning sewage purification treatment device

Abstract

The embodiment of the invention discloses a self-cleaning sewage purification treatment device. The self-cleaning sewage purification treatment device comprises a mounting cover with a downward opening; a filter barrel is connected into an opening in the bottom end of the mounting cover through a thread; a partition cylinder with a downward opening is arranged in the middle of the interior of themounting cover; a water inlet and a water outlet which communicates with the partition cylinder are respectively formed in the outer side of the mounting cover; a backflushing opening extending to theouter side of the mounting cover is formed in one side of the partition cylinder; one end of the backflushing opening is obliquely cut on the outer side of the partition cylinder, so that clear waterflowing into the partition cylinder through the backflushing opening flows around the inner wall of the partition cylinder, continuous thrust is generated on fan blades in the process again, a rotaryframe is driven to rotate around the outer side of a screen cylinder, and the interior of the device is continuously cleaned through the rotary frame; a push rod mechanism can drive the rotating rotary frame to do reciprocating up-down sliding action, and when the device is used for backwashing, the effect of cleaning the outer side of the screen cylinder and the inner side of the filter barrel is better.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of sewage treatment, in particular to a self-cleaning sewage purification treatment device. Background technique [0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Removing visible impurities is a relatively important link in the process of sewage treatment. In the prior art, grilles or The filter screen intercepts the impurities to achieve the purpose of separating the water body from the impurities. [0003] However, in the long-term use of the filter screen, a large amount of impurities will adhere to the surface of the filter. The conventional treatment method is to use the motor or cylinder to drive the cleaning brush to scrub the outside of the filter screen, which is highly dependent on the drive device. When the drive device is damaged When the cleaning work cannot be carried ou...

Problems solved by technology

[0005] For this reason, the embodiment of the present invention provides a self-cleaning sewage purification treatment device to solve the problem that the automatic cleaning in the prior art is highly dependent on the driving device, and the cleaning mechanism generally performs a single reciprocating movement on the outside of the filter screen. Causes the effect of automatic cleaning to be unsatisfactory
