Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to sewage treatment, and more specifically, particularly relates to an automatic ultra-fine grid for sewage treatment filtration. Background Art
[0002] Removing the screen from sewage is the first step in urban sewage treatment. The normal operation of this process plays an important role in protecting mechanical equipment and pipelines and ensuring the normal operation of subsequent processes. Traditional screen machines have low efficiency in intercepting inorganic matter in incoming water. They are very likely to get caught by fibrous materials such as hair, and are easily stuck during insertion. It is difficult to flush them out by backwashing. As the running time accumulates, the debris in the incoming water continues to accumulate, resulting in a decrease in the effective filtration area of the screen, thereby reducing the backwashing efficiency. At the same time, the screen interception cannot be effectively cleaned during operation, and the rear end drain hole is easily blocked.

[0017] The clamping plates on both sides of the third ultra-fine grid can help guide the incoming sewage and ensure that it is evenly distributed over the entire width of the grid. This can avoid flow concentration or bias to one side, improve the flow balance performance of the grid, and ensure that each part is properly treated. The sewage treatment grid may be subjected to certain forces and pressures during the treatment process. The reinforcement clips help prevent the grid structure from deformation or damage, improve its stability and durability, and the setting of the water inlet baffle and the reinforcement clips can effectively prevent solid waste from escaping from the grid area during the sewage treatment process, and ensure that all waste is captured and processed by the grid to prevent it from entering subsequent treatment units, thereby improving treatment efficiency.
