One end of the spring 20 is fixedly connected to the inner wall of the box body 1, and the other end of the spring 20 contacts the outer wall of the partition 15. The half gear 17 with the transmission rod 13 drives the partition 15 to move, so that the partition 15 squeezes the spring 20. When the half gear 17 rotates to the side that is not engaged with the rack 21, the half gear 17 is released. The meshing effect of the rack 21, at this time, because there is no force to push the spring 20 to contract, the spring 20 will drive the partition 15 to move in the opposite direction, and the rear side of the partition 15 is fixedly connected with the rack 21, and the outer wall of the rack 21 is meshed with the half gear 17. When the rack 21 is meshed with one side of the half gear 17, the partition 15 is driven to move. When the rack 21 is not meshed with the other side of the half gear 17, the partition 15 will be pushed back by the spring 20, and the half gear 17 will mesh with the rack 21 again when it rotates again. When installing the partition 15, the connecting rod 10 connected to the upper end of the transmission rod 13 is not in a fixed state, so that the rack 21 can drive the half gear 17 to rotate, which is convenient for the installation of the partition 15. The end is fixedly connected to the lower end of the transmission rod 13, and the rotation of the transmission rod 13 drives the half gear 17 to rotate to provide a fixing effect. The lower end of the partition 15 is fixedly connected to the scraper 18, and the lower end of the scraper 18 contacts the outer wall of the filter screen 16. The partition 15 drives the scraper 18 to move left and right and contact with the surface of the filter screen 16 to scrape off the impurities attached to the surface of the filter screen 16 to prevent these impurities from clogging the filter screen 16 and affecting the filtering effect. The right end of the guide rod 19 contacts the left end of the box door 3. When the spring 20 causes the partition 15 to move in the opposite direction, the other side of the partition 15 will contact the inner side of the box door 3. The box door 3 is provided with a buffer pad on the inside to reduce the impact of the reverse movement of the partition 15 on the box door 3.

[0032] refer to Figure 1A box door 3 is fixedly installed on the right outer wall of the box body 1. When the box door 3 is opened, the partition 15 can be removed from the guide rod 19 to take out the remaining filtered solids and the filter screen 16, which is convenient for removal, replacement and cleaning. A feed port 2 is fixedly connected to the left side of the box body 1. The feed port 2 is used to pour the liquid mixture to be processed. A valve 4 is fixedly installed on the lower end of the right side of the box body 1. The valve 4 is a prior art. The valve 4 can control the outflow of the liquid. The valve 4 is used to discharge the filtered liquid.

[0033] refer to Figure 2 、 Figure 3 The inner wall of the box body 1 is slidably connected with an extrusion plate 6, which pressurizes the mixture in the upper half of the box body 1 to accelerate the filtering effect. There is a vertical plate on the left side of the extrusion plate 6. When the extrusion plate 6 is pressed down, it is used to prevent the liquid from the feed port 2 from flowing to the upper side of the extrusion plate 6. The upper end of the extrusion plate 6 is fixedly connected with an extrusion support rod 7. The lower section of the extrusion support rod 7 can shrink after the extrusion plate 6 is squeezed by the solid to prevent the extrusion plate 6 from pressing down to squeeze the solid and causing damage to the supporting part. The outer wall of the extrusion support rod 7 is slidably connected to the inner wall of the box body 1, and the inner wall of the box body 1 provides a guide for the extrusion support rod 7 so that the extrusion support rod 7 can only move up and down. A moving wheel 8 is fixedly connected to the middle of the extrusion support rod 7. The middle of the moving wheel 8 is a strip groove, so that the protrusion 11 drives the moving wheel 8 up and down when it rotates on the wheel disc 12. The inner wall of the moving wheel 8 is slidably connected to the protrusion 11. When the protrusion 11 moves on the inner wall of the moving wheel 8, it will cause the moving wheel 8 to move when it moves up and down, and the protrusion 11 will only move when it moves left and right. The inner wall of the wheel 8 slides, the outer wall of the protrusion 11 is fixedly connected to the wheel disc 12, the wheel disc 12 provides a fixing effect for the protrusion 11, the outer wall of the wheel disc 12 is fixedly connected with the connecting rod 10, and the rotation of the connecting rod 10 drives the wheel disc 12 to rotate. The inner wall of the box body 1 is fixedly connected with the fixing rod 9, and the inner wall of the fixing rod 9 is slidably connected to the outer wall of the extrusion support rod 7. The fixing rod 9 provides a fixing effect for the extrusion support rod 7. The inner wall of the box body 1 is fixedly connected with the fixing plate 14, and the outer wall of the connecting rod 10 rotates with the inner wall of the fixing plate 14. Dynamic connection, the fixed plate 14 provides a supporting effect for the connecting rod 10, the outer wall of the box body 1 is fixedly connected to the motor 5, the output end of the motor 5 is fixedly connected to the left end of the connecting rod 10, so that the motor 5 drives the connecting rod 10 to rotate, and the outer wall of the connecting rod 10 is connected to the upper end of the transmission rod 13 through a bevel gear. One group of bevel gears is fixedly connected to the outer wall of the connecting rod 10, and the other group of bevel gears is fixedly connected to the upper end of the transmission rod 13. The bevel gears convert the lateral rotation of the connecting rod 10 into the vertical rotation of the transmission rod 13.

[0034] Working principle: When in use, first pour the liquid to be treated from the feeding port 2, the motor 5 drives the wheel 12 to rotate, and the moving wheel 8 drives the extrusion support rod 7 to move upward to make the extrusion plate 6 rise. When the extrusion plate 6 rises, the liquid to be treated will flow into the inside of the box body 1, and the wheel 12 continues to rotate to make the extrusion support rod 7 drive the extrusion plate 6 to move downward. The side of the extrusion plate 6 will prevent the liquid behind from continuing to enter the box body 1, so that the interior of the box body 1 is sealed. When the extrusion plate 6 continues to press down, it will exert pressure on the liquid so that the liquid inside can be filtered faster.

[0035] The scraper 18 at the lower end of the partition 15 moves back and forth on the surface of the filter 16 to prevent impurities from being deposited on the surface of the filter 16.

[0036] After filtering, it is necessary to remove the solids and impurities inside the box body 1, open the box door 3, pull out the partition 15 from the guide rod 19 to remove the solids and impurities inside the box body 1, when the partition 15 is pulled out and installed, the motor 5 does not rotate and the half gear 17 will not be fixed, so that the half gear 17 will not affect the pulling out and installation of the partition 15, and the filter screen 16 is plugged into the inside of the box body 1 and can be pulled out from the box door 3, which is convenient for cleaning the partition 15 and the filter screen 16 and convenient for next use.
