[0002] In the production of liquid fertilizer, the addition of anti-caking agents is a key step in ensuring product quality. However, anti-caking agents for liquid fertilizer are prone to being mixed with impurities during preparation and storage, and need to be purified by filters. Current filtration equipment used for liquid fertilizer anti-caking agents generally suffers from the problem of inconvenient filter cleaning. On the one hand, after filtration, a large amount of impurities adhere to the inner wall of the filter screen, which existing equipment cannot clean directly. It often requires disassembling the entire filter screen, which is not only cumbersome and time-consuming, but also affects the continuity of filtration operations. On the other hand, fine impurities are easily left inside the pores of the filter screen. These impurities are difficult to remove completely through conventional cleaning methods. Long-term accumulation will lead to filter screen blockage, reduce filtration efficiency and accuracy, and even require frequent filter screen replacement, increasing the operating cost of the equipment.

This structural design can effectively... To improve filtration accuracy and completely remove impurities from the liquid fertilizer anti-caking agent, a baffle 6 is inserted into the bottom of the filter screen 5. The function of the baffle 6 is to temporarily block the material from flowing directly out of the bottom of the filter screen 5 during the filtration process, so that the material can be fully filtered by the filter screen 5. A slag discharge component is provided at the bottom of the baffle 6. A threaded block 10 is fixed at the center of the top of the outer shell 1. The internal thread of the threaded block 10 is connected to a drive rod 11. The drive rod 11 and the internal thread of the threaded block 10 are engaged to ensure that precise up and down movement can be achieved during rotation. A cleaning component is provided at the bottom of the drive rod 11.

[0015] The slag discharge component includes a sealing plate 7, which is inserted into the bottom end of the outer shell 1. The size of the sealing plate 7 matches the bottom opening of the outer shell 1, allowing it to be tightly inserted into the bottom end of the outer shell 1. A sealing ring mounting groove is machined at the connection between the sealing plate 7 and the outer shell 1. After the sealing ring is embedded in it, it can ensure that the material will not leak from the gaps during the filtration process. A support plate 8 is fixed to the bottom end of the sealing plate 7. Through holes are opened on both sides of the support plate 8, and fasteners 9 are threaded inside the through holes. The fasteners 9 are a combination of high-strength bolts and nuts. The length of the bolts is determined according to the thickness of the support plate 8 and the outer shell 1 to ensure that the support plate 8 can be firmly fixed to the outer shell 1. A sealing ring is machined at the connection between the sealing plate 7 and the outer shell 1.

[0016] The cleaning component includes a scraper 12, which is fixed to the outer wall of the drive rod 11. The diameter of the scraper 12 matches the inner diameter of the filter screen 5. The scraper 12 ensures full contact with the inner wall of the filter screen 5 during the cleaning process. A groove plate 13 is fixed to the bottom end of the drive rod 11. A through hole is formed inside the drive rod 11, and a connecting water pipe 14 is provided inside the through hole. The connecting water pipe 14 is used to transport cleaning water through the groove plate 13 to the inside of each high-pressure nozzle.

[0017] The interior of the trough plate 13 forms a cavity, and the four corners of the outer wall of the trough plate 13 are provided with through holes, and a high-pressure nozzle is installed inside each through hole. The outer wall of the scraper 12 is machined with a hard brush, so as to facilitate cleaning when it comes into contact with the filter screen 5.

[0018] Working Principle: When a filter for liquid fertilizer anti-caking agents is first used, the liquid waste anti-caking agent enters the casing 3 through the inlet pipe 4 and passes through the filter screen 5. Impurities from this process fall downwards to the bottom of the filter screen 5, and the filtered liquid waste is discharged from the outlet 2. When it is necessary to clean the surface and interior of the filter screen 5, the user first removes the fixing piece 9 from the support plate 8, then pulls the support plate 8 downwards. Pulling the support plate 8 causes the sealing plate 7 and the stop block 6 to move downwards. When the stop block 6 moves downwards and separates from the bottom of the filter screen 5, some impurities are discharged from the opening at the bottom of the outer casing 1. Then, the user uses an external control unit to supply water to the inside of the connecting water pipe 14, and the water is then discharged through the connecting water pipe 14. The filter screen 5 is sprayed through the slotted plate 13 and the high-pressure nozzle. Then, the user rotates the drive rod 11. When the drive rod 11 rotates, it moves downward in cooperation with the threaded block 10. Then, the drive rod 11 moves downward, driving the slotted plate 13 and the scraper 12 to move downward at the same time. During the downward movement of the scraper 12, it can clean the impurities attached to the inner wall of the filter screen 5 and push them downward. Through the cooperation of the slotted plate 13 and the high-pressure nozzle, the impurities in the holes of the filter screen 5 can be cleaned. The cleaned impurities and cleaning water are discharged through the opening at the bottom of the outer shell 1. After cleaning, the scraper 12 and the slotted plate 13 are reset by the drive rod 11. After reset, the user inserts the support plate 8, the sealing plate 7 and the stop block 6 into the bottom of the outer shell 1. After the sealing plate 7 is attached to the bottom of the outer shell 1, it is fixed by the fastener 9.
