Description

Technical Field

[0001] The utility model belongs to the field of wastewater filtration, and particularly relates to a wastewater filtration device for sewage treatment. Background Art

[0002] The wastewater filtration device for sewage treatment is a device specially used to remove solid particles, colloids, organic matter and other pollutants in wastewater. When sewage is discharged, it is usually filtered through a filter plate first, and the filtered wastewater will flow into the sewage treatment tank. The sewage filter tank is a device specially used to treat sewage. Its core function is to filter and purify water quality. It uses physical methods to filter out suspended matter, particulate matter, oil and other impurities in sewage, so that the water quality is significantly improved. The water quality after treatment by the sewage filter tank can meet certain emission standards, and the impact on the environment is effectively controlled.

[0003] A Chinese patent with publication number "CN218130196U" discloses a filtering structure of a sewage treatment device, including a sewage treatment box, a filter plate penetrating the left side of the sewage treatment box, a top box fixedly connected to the left side of the sewage treatment box, a motor fixedly connected to the left side of the bottom of the inner cavity of the top box, a rotating rod fixedly connected to the output end of the motor, a gear 1 fixedly connected to the output end of the rotating rod, a rotating rod movably connected to the interior of the top box laterally through a bearing, and a gear 2 is sleeved on the left side of the surface of the rotating rod.

[0004] However, this device still has some shortcomings. When filtering wastewater through the filter plate, the particulate pollutants in the wastewater will be blocked by the filter plate. Under the long-term infusion of wastewater, the filter plate will be blocked by the pollutants. Because the filter plate is located on the inner side of the sewage treatment tank, the user can only clean its surface by disassembling and assembling the filter plate, thereby reducing the working efficiency of wastewater filtration.
