A locking plate 801 is slidably installed inside the sleeve plate 803. A No. 1 spring 802 is fixedly installed at both the front and rear ends of one side of the inner wall of the sleeve plate 803. A hinge plate 11 is hingedly installed on one side of the lower end face of the outer wall of the water tank 5.

[0028] A fixing frame 9 is fixedly installed on one side of the upper end face of the hinge plate 11. A filter plate 12 is snapped into the fixing frame 9. Fixing shells 10 are fixedly installed at both ends of the outer wall of the fixing frame 9. Fixing mechanisms 13 are installed inside the two fixing shells 10. Both fixing mechanisms 13 include inserts 1302. U-shaped rods 1303 are fixedly installed on one side of the two inserts 1302. Two springs 1301 are movably sleeved at both ends of the outer wall of the two U-shaped rods 1303.

[0029] Specifically, the screw rod 6 is driven by the motor 7 to rotate, thereby achieving the scraping and cleaning effect on the bottom surface of the inner wall of the filter tank 1 through the scraper 2. The water tank 5 can transfer and hold the pulp that has undergone preliminary filtration through the filter tank 1. The rotation angle of the hinge plate 11 can be limited by the positioning mechanism 8. The filter plate 12 can be snapped into place by the fixing frame 9. The position of the filter plate 12 can be locked by the fixing mechanism 13.

[0030] Reference Figure 2 The sleeve plate 803 is fixedly installed on one side of the lower end face of the outer wall of the water tank 5, and one end of each of the two No. 1 springs 802 is fixedly connected to one side of the card plate 801.

[0031] Specifically, the lever plate 801 can slide within the sleeve plate 803 by extending and retracting. The elastic force of the first spring 802 can push the lever plate 801 outward, thereby restricting the rotation of the hinge plate 11.

[0032] Reference Figure 4 Two inserts 1302 are slidably disposed inside the two fixed shells 10 respectively. The two ends of the two second springs 1301 are fixedly connected to the inner walls of the two fixed shells 10 and the two inserts 1302 respectively. The two ends of the two U-shaped rods 1303 slide through one side of the outer wall of the two fixed shells 10 respectively.

[0033] Specifically, pulling the U-shaped rod 1303 can move the insert 1302, and the elastic force of the two second springs 1301 can keep the insert 1302 in the position inside the fixed shell 10 in the relaxed state.

[0034] Reference Figure 4The filter plate 12 has a groove 14 at the center of both the front and rear ends on one side. The two inserts 1302 slide through the fixing frame 9 and are respectively embedded in the two grooves 14.

[0035] Specifically, by sliding the two inserts 1302 through the fixing frame 9 and embedding them into the groove 14, the position of the filter plate 12 can be fixed, preventing the filter plate 12 from falling out of the fixing frame 9.

[0036] Reference Figure 1 A sliding rod is fixedly installed at the center of the rear end face of the outer wall of the filter tank 1. The threaded rod 6 is threaded through the front end of the scraper 2, and one end of the threaded rod 6 is fixedly connected to the output end of the motor 7.

[0037] Specifically, the slide bar slides through the rear end of the scraper 2, and the screw rod 6 is driven to rotate by the motor 7, thereby enabling the scraper 2 to slide along the slide bar.

[0038] Reference Figure 1 A feeding trough is fixedly installed on one side of the upper end face of the filter tank 1, and a baffle 3 is hinged to one side of the bottom end face of the inner wall of the filter tank 1. The baffle 3 is interference fit with the inner wall of the filter tank 1.

[0039] Specifically, pulp is poured into the filter tank 1 through the feeding trough. After the scraper 2 scrapes the impurities on the bottom filter screen of the filter tank 1 to one side, the baffle 3 can be pulled open to clean the impurities inside the filter tank 1.

[0040] Reference Figure 1 A filter screen is installed at the center of the bottom surface of the inner wall of the filter tank 1, and a discharge pipe 4 is fixedly installed at the center of one side of the outer wall of the water tank 5.

[0041] Specifically, the pulp can be initially filtered through the filter screen, and the filtered pulp can be discharged and collected through the discharge pipe 4.

[0042] Working principle: Pulp is poured into filter tank 1. After initial filtration in filter tank 1, the filtered pulp enters water tank 5. Then, it undergoes secondary filtration through filter plate 12 to enhance the filtration effect. When the filter screen and filter plate 12 become clogged after prolonged use, motor 7 is started to rotate threaded rod 6, which drives scraper 2 to scrape the bottom surface of the inner wall of filter tank 1, thereby cleaning the filter screen. Then, the clamping plate 801 is pushed to one side to move it inward to the sleeve plate 803, thereby disengaging it from the lower surface of hinge plate 11. At this time, hinge plate 11 can be rotated to remove filter plate 12 from water tank 5. Then, the two U-shaped rods 1303 are pulled to disengage the two inserts 1302 from the two slots 14 respectively. At this time, filter plate 12 can be pulled out for cleaning and replacement, thus preventing the filter screen and filter plate 12 from becoming clogged and reducing the filtration efficiency of pulp.
