The filter cartridge 100 has a cylindrical tubular structure, and a side wall of the cylindrical tubular structure has a filter screen for preventing foreign materials outside the filter cartridge 100 from entering the inside of the filter cartridge 100.

As shown in fig. 1, in one example, the cleaning brush 220 has a strip-like structure and extends in the axial direction of the filter cartridge 100. Further, the cleaning brush 220 extends from one end to the other end of the filter cartridge 100. The cleaning region may cover the entire outer sidewall of the filter cartridge 100 as the cleaning brush 220 moves along the circumferential direction of the filter cartridge 100, improving the cleaning effect.

In one example, the brush holder 210 includes a rotating base rotatably coupled to one end of the filter cartridge 100 and a mounting arm. Specifically, the filter cartridge 100 is vertically disposed, and a rotating seat, which prevents immersion in water, is provided at the upper end of the filter cartridge 100. A mounting arm is connected to the rotary base and extends in the axial direction of the filter cartridge 100, and a cleaning brush 220 is provided on the mounting arm. The driving mechanism 230 is connected to the rotary base for driving the rotary base to rotate. The rotation of the rotating base drives the mounting arm to rotate, i.e. the cleaning brush 220 is driven to move along the circumferential direction of the filter cartridge 100.

The brush holder 210 may be made of stainless steel to prevent rust and damage.

In one example, there are a plurality of mounting arms disposed around the filter cartridge 100, each mounting arm having a cleaning brush 220 disposed thereon. Further, the plurality of mounting arms are evenly distributed. In one example, there are four mounting arms, each having a cleaning brush 220 disposed thereon.

Further, after the cleaning brush 220 is cleaned, the liquid level inside the filter cartridge 100 rises, the difference between the liquid levels inside and outside the filter cartridge 100 decreases, and when the difference between the liquid levels reaches a second set value, the control device controls the brush holder 210 to stop operating, and the second set value is smaller than the first set value. Thereby achieving automatic stopping of the cleaning device. In other examples, the cleaning device may be automatically stopped after a set period of time for cleaning.

In one example, the filter apparatus 10 further comprises an alarm 700, and the alarm 700 is electrically connected to the control device. When the action of the brush holder 210 reaches a first set time (for example, 2 minutes) and the liquid level difference value does not reach a third set value, the control device controls the alarm 700 to give an alarm to remind a worker to perform inspection and maintenance. Wherein the third set value is smaller than the first set value. In one example, the third set point is equal to the second set point. The first set time length can be set and adjusted.

In one example, the water pump 300 is electrically connected to the control device, and when the brush holder 210 is operated for a second set time (e.g. 2 minutes) and the liquid level difference does not reach a fourth set value, the control device controls the water pump 300 to stop operating, and the mechanical seal of the water pump is damaged due to dry grinding. The fourth setting is less than the first setting, and in one example, the fourth setting is equal to the second setting. The second set time length can be set and adjusted. In one example, the second set duration is equal to the first set duration.

Further, the cleaning apparatus may be provided with a timed cleaning mode and a manual on mode in addition to the liquid level difference control.

In the filtering apparatus 10, the cleaning brush 220 is disposed on the outer side wall of the filter cartridge 100, and the brush can move along the circumferential direction of the filter cartridge 100 under the driving of the brush holder 210, so as to clean the blockage attached to the filter cartridge 100.
