Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to an anti-clogging sewage filter. Background Technology

[0002] A wastewater filter is a device used to remove impurities from water. It works by physically blocking suspended solids, particulate matter, and other solid substances in the water using filter screens or cartridges, thereby purifying the water. These devices are widely used in various settings, including industrial applications and wastewater treatment plants, and play a vital role in improving water quality and protecting the aquatic environment.

[0003] my country's utility model announcement number CN 221797120 U discloses an anti-clogging sewage treatment device that relies on the gravity of water flow to drive the filter screen to vibrate and clean the filter screen blockage. However, due to the low amplitude and frequency of the filter screen vibration, the anti-clogging effect is not good and needs further improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an anti-clogging sewage filter.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A clog-resistant wastewater filter includes a cylindrical body and legs fixed to the cylindrical body; a pipe with an open upper end is fixed to the center of the bottom of the cylindrical body, a filter screen cylinder is rotatably connected to the upper end of the pipe, a bracket is fixed to the upper end of the cylindrical body, a geared motor is fixed to the bracket, and the output end of the geared motor is fixed to the upper end of the filter screen cylinder; a liquid outlet pipe communicating with the lower end of the pipe is fixed to the bottom of the cylindrical body, and a liquid outlet valve is provided on the liquid outlet pipe; a sewage discharge pipe is fixed to the lower part of the cylindrical body, and a sewage discharge valve is provided on the sewage discharge pipe.

[0007] Preferably, a horn cover is fixed to the upper part of the tube, with the larger diameter end of the horn cover facing downwards.

[0008] Preferably, the bottom surface of the cylinder is an inclined surface, and the drain pipe is located on the lower side of the bottom of the cylinder.

[0009] Preferably, the upper end of the cylinder is provided with a top plate, the top plate is provided with an openable and closable cover, and the top plate is provided with a liquid inlet.

[0010] Preferably, the cover is provided with a handle.

[0011] Preferably, the upper end of the filter cylinder is connected to the output end of the geared motor via a connecting shaft.

[0012] The above technical solution has the following advantages:

[0013] This invention employs a geared motor to intermittently drive the filter cylinder to rotate. Utilizing the centrifugal force generated during this rotation, it effectively achieves automatic cleaning of blockages. This innovative mechanism not only significantly improves the self-cleaning ability of the filter cylinder, avoiding the clogging problems of traditional filtration devices, but also greatly enhances the working efficiency and stability of the filter cylinder by continuously maintaining unobstructed flow of the filter media, ensuring filtration effectiveness and system reliability over extended periods of operation.
