The bottom of the filter cartridge 2 is in an inverted truncated cone shape, which is convenient for discharging impurities out of the device. The surface of the filter cartridge 2 is connected with a liquid outlet pipe 3. The bottom of the filter cartridge 2 is connected with a liquid inlet pipe 4. The top of the filter cartridge 2 is connected with a water inlet pipe. Valves are installed on the outsides of the water inlet pipe, the liquid inlet pipe 4 and the liquid outlet pipe 3 to control the flow of the water inlet pipe, the liquid inlet pipe 4 and the liquid outlet pipe 3. A filter plate 5 is installed inside the filter cartridge 2. The filter plate 5 is a mesh plate and is in a truncated cone shape, which is convenient for filtering impurities in vehicle urea. The inner wall of the filter plate 5 is evenly spaced with inclined scrapers 6, and the inclined scrapers 6 are fixedly connected to a long rod 7 through a connecting rod. The surface of the long rod 7 is fixedly connected with vertical scrapers 8 at equal intervals through support rods, and the vertical scrapers 8 abut against the inner wall of the filter cylinder 2. The top of the long rod 7 is fixedly connected with a bevel gear A9, and the surface of the bevel gear A9 is meshingly connected with a bevel gear B10. A protection box is installed on the outside of the bevel gear A9 and the bevel gear B10, and a sealed bearing is installed on the bottom of the protection box. The long rod 7 is installed inside the sealed bearing. The protection box is used to protect the bevel gear A9 and the bevel gear B10. The sealed bearing is used to ensure the normal rotation of the long rod 7. L-shaped plates are fixedly connected to both sides of the top of the U-shaped frame 1, and the two ends of the intermediate shaft of the bevel gear B10 are respectively fixedly connected to one side of the two L-shaped plates for fixing the intermediate shaft of the bevel gear B10.
[0027] The rotating assembly is used to rotate the filter cartridge 2, so as to discharge impurities out of the filter cartridge 2. The rotating assembly includes two connecting rods 11 fixedly connected to the surface of the filter cartridge 2. The connecting rods 11 are rotatably installed on one side of the U-shaped frame 1. The intermediate shaft of the bevel gear B10 is penetrated and arranged inside the two connecting rods 11. The surface of the right connecting rod 11 is sleeved with a gear A12.

[0028] The implementation principle of a vehicle urea filtering device in the embodiment of the present application is as follows: vehicle urea is introduced into the interior of the filter cartridge 2 from the liquid inlet pipe 4. As the liquid continues to increase, the liquid passes through the filter plate 5 and enters the top of the filter plate 5. The impurities in the vehicle urea are affected by the filter plate 5 and are located below the filter plate 5, thereby achieving filtering of the vehicle urea. After the filtering is completed, the motor 14 is started to rotate the filter cartridge 2 half a circle, so that the remaining vehicle urea liquid passes through the filter plate 5 and flows out from the liquid outlet pipe 3. After the liquid flows out completely, the motor 14 is started to reset the filter cartridge 2, so that the impurities flow out of the filter cartridge 2 through the liquid inlet pipe 4. After the impurity discharge is completed, water is added to the filter cartridge 2 through the water inlet pipe to rinse the surface of the filter plate 5, and the impurities attached to the lower surface of the filter plate 5 are washed off to complete the cleaning of the filter plate 5. After filtering the vehicle urea, the device is convenient for directly rinsing the filter plate 5, which reduces the situation where impurities adhere to the pore size of the filter plate 5 and affect the filtering of the vehicle urea.
[0029] During the rotation of the filter cartridge 2, the bevel gear B10 is acted upon by the bevel gear A9, so that the bevel gear B10 drives the long rod 7 to rotate, thereby driving the bevel scraper 6 and the vertical scraper 8 to rotate, scraping off the impurities attached to the inner wall of the filter plate 5 and the impurities attached to the inner wall of the filter cartridge 2, so that the impurities fall to the bottom of the filter cartridge 2 and flow out of the device through the liquid inlet pipe 4, thereby reducing the situation where the impurities clog the aperture of the filter plate 5.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
