The hopper 8 can make it easy to add the liquid medicine to be filtered into the filter barrel 2, and the filtered liquid medicine can be easily discharged to the outside through the discharge pipe 10 and the discharge solenoid valve 9. The sewage outlet at the bottom of the bottom plate 1 is connected to one end of the sewage pipe 11, and the sewage pipe 11 is equipped with a sewage solenoid valve 12. The sewage solenoid valve 12 is electrically connected to the control module 4. The impurities at the bottom of the filter cartridge 3 can be easily discharged to the outside through the sewage pipe 11 and the sewage solenoid valve 12, which is convenient for cleaning the impurities in the filter cartridge 3. The cleaning mechanism 5 and the automatic control mechanism 6 are installed in the filter barrel 2. Four supporting legs 7 are fixedly installed at the bottom of the bottom plate 1, and rubber pads 13 are fixedly installed at the bottom of the supporting legs 7. The rubber pads 13 can increase the friction at the bottom of the supporting legs 7, thereby improving the stability of the filtering device when in use;

The cleaning mechanism 5 comprises a fixed rod 51, a scraper 52, a brush 53, a rotating rod 54 and a motor 55. The motor 55 is fixedly mounted at the middle of the bottom of the base plate 1. The output shaft of the motor 55 passes through the through hole at the bottom of the base plate 1 and is fixedly connected to the lower end of the rotating rod 54. The upper end of the rotating rod 54 is rotatably connected to the top of the filter barrel 2. No less than three fixed rods 51 are fixedly mounted on the side of the rotating rod 54. The other end of the fixed rod 51 is fixedly connected to the side of the scraper 52. The other side of the scraper 52 is fixedly mounted with a brush 53. The brush 53 contacts the inner side of the filter cartridge 3. The liquid medicine can be filtered through the filter cartridge 3 to remove impurities in the liquid medicine. The rotating rod 54 is driven to rotate by the motor 55, so that the rotating rod 54 drives the fixed rod 51 and the scraper 52 to rotate, so that the brush 53 on the scraper 52 scrapes off the impurities on the inner wall of the filter cartridge 3, thereby cleaning the filter cartridge 3 to prevent the filter cartridge 3 from being blocked and affecting the filtration of the liquid medicine.

The automatic control mechanism 6 includes an air vent 61, a support rod 62, a micro switch 63, a fixed cylinder 64 and a float 65. The fixed cylinder 64 is fixedly installed on one side of the top of the filter barrel 2, the fixed cylinder 64 is located inside the filter barrel 3, and a float 65 is movably installed in the fixed cylinder 64. The support rod 62 is fixedly installed on the top of the fixed cylinder 64, and a micro switch 63 matched with the float 65 is fixedly installed in the middle of the bottom of the support rod 62.

The working principle of the utility model is as follows: the external power supply is turned on, and the liquid medicine to be filtered is added from the feed hopper 8 to the filter barrel 2. The liquid medicine can be filtered through the filter cartridge 3, so that impurities remain in the filter cartridge 3. The filtered liquid medicine will be discharged to the outside through the discharge pipe 10. As the filtration proceeds, more and more impurities are on the inner wall of the filter cartridge 3. At this time, the liquid medicine added to the filter cartridge 3 is difficult to be filtered through the filter cartridge 3, and the liquid level in the filter cartridge 3 will rise. In the process of the liquid level rising, the float 65 will rise in the fixed cylinder 64 along with the liquid level, and the rising float will trigger the micro switch 63. At this time, the control module 4 will automatically control the motor 55 to work, so that the motor 5 The output shaft of 5 drives the rotating rod 54 to rotate, so that the rotating rod 54 drives the fixed rod 51 and the scraper 52 to rotate, so that the brush 53 on the scraper 52 cleans the inner wall of the filter cartridge 3 and scrapes off the impurities on the inner wall of the filter cartridge 3. At this time, the filter cartridge 3 can continue to filter the liquid. As the filtering progresses, the liquid level in the filter cartridge 3 will decrease. At this time, the float 65 will decrease with the liquid level, and the float 65 will separate from the micro switch 63. At this time, the control module 4 will automatically control the motor 55 to stop working. After the filtering is completed, the control module 4 can control the sewage discharge solenoid valve 12 to open, so that the impurities at the bottom of the filter cartridge 3 can be discharged to the outside from the sewage discharge pipe 11. The circuit connection involved in the utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through limited tests, which belongs to the widely used existing technology.
