Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a self-cleaning sewage treatment equipment. Background Technology

[0002] In the treatment of domestic and industrial wastewater, the wastewater is usually treated first through a filtration device. During the filtration process, flocculent matter in the wastewater can clog the filter screen, causing obstructed water flow and affecting wastewater treatment efficiency. Regular cleaning of the blockages is typically used to maintain treatment efficiency, but this is cumbersome and labor-intensive.

[0003] In the prior art, there are already sewage treatment devices that can automatically clean the filter screen. For example, the invention patent CN111514639B provides a sewage filtration device that automatically cleans the filter screen, including a filter machine with a filter chamber and a filter device inside. A telescopic mechanism is provided between the brush rod and the positioning block. A locking device can lock the position of the lower support. A heating device is located below the locking device. A transmission device can control the simultaneous raising and lowering of the inlet lifting plate and the outlet lifting plate. This invention cleans the filter screen comprehensively by drying and cleaning it simultaneously. During the cleaning process, the filter screen and dirt are dried, removing excess moisture. This allows for more efficient removal of accumulated dirt and keeps the filter screen dry, ensuring a high-quality filtration effect. Simultaneously, this device can promptly discharge the filtered water, dirt, and water vapor, preventing clogging and ensuring the equipment's operation.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: the solution in the patented technology requires a complex power mechanism to achieve automatic cleaning, which is costly. Utility Model Content

[0006] The technical solution to the problem solved by this utility model is as follows: An embodiment of this utility model provides a self-cleaning sewage treatment device, including a water pump, an inlet pipe, and a filter. One end of the inlet pipe is connected to the inlet of the water pump, and the other end is equipped with a filter. The filter includes a cylinder, a turbine, a cover, and a cleaning plate. The cylinder is a cylindrical shape with openings at both ends. The rear end of the cylinder is connected to the inlet pipe. The cover is threaded onto the front opening of the cylinder. The turbine is mounted on the front opening of the cylinder via a rotating shaft. The cleaning plate is mounted on the rotating shaft of the turbine. The front of the cover has multiple through holes, and the cleaning plate fits snugly against the front of the cover. The inlet pipe wraps around the rear end of the cylinder, and the outside of the inlet pipe is secured with cable ties or wire to fix the inlet pipe to the cylinder.

[0007] As an optimization, the filter further includes a top plate and a pressure plate. The diameter of the front end of the cylinder is larger than the diameter of the rear end. A boss is provided in the middle of the cylinder. The top plate and pressure plate are circular plates with mounting holes in the center.

The pressure plate fits into the cylinder cover. The two ends of the turbine shaft are respectively installed in the mounting holes in the center of the top plate and the pressure plate, and then pressed together by the cylinder cover.

[0008] As an optimization, a bearing is also provided between the turbine's shaft and the top plate and pressure plate.

[0009] As an optimization, the turbine includes a rotating shaft and multiple spiral blades rotating in the same direction. A threaded hole is provided at the center of the front end face of the turbine shaft, and a rectangular groove is provided at the center of the front end face of the turbine shaft. A rectangular protrusion corresponding to the rectangular groove is provided on the rear end face of the cleaning plate. The rectangular protrusion is inserted into the rectangular groove, and the cleaning plate is fixed to the rotating shaft of the turbine by screws.

[0010] As an optimization, the cleaning plate includes a central annular block and multiple scrapers surrounding the annular block. A through hole is provided in the center of the cylinder cover. Screws pass through the annular block and the through hole in the center of the cylinder cover in sequence. The screws are installed in the threaded holes on the turbine shaft.

[0029] like Figure 5 As shown, the filter 5 also includes a top plate 52 and a pressure plate 54. The diameter of the front end of the cylinder 51 is larger than the diameter of the rear end. A boss is provided in the middle of the cylinder 51. The top plate 52 and the pressure plate 54 are circular plates with mounting holes in the center. The top plate 52 fits into the boss in the middle of the cylinder 51. The rotating shaft at one end of the turbine 53 is installed in the mounting hole in the center of the top plate 52.
