A support frame 18 is fixedly connected to the outside of the lower half 2 of the filter cylinder, and a conveying pipe 25 is fixedly connected to the bottom of the support frame 18 to send the filtered material or liquid into a concentration device. The other end of the conveying pipe 25 is fixedly connected to a concentration cylinder 26 for... The component for further concentrating liquid materials includes a conveying port 27 at the top of the concentration cylinder 26, which is connected to a conveying pipe 25, allowing the filtered material to enter the concentration cylinder 26. A vacuum pump 28 is embedded outside the concentration cylinder 26, which creates a negative pressure environment by extracting air. A temperature controller 29 is also embedded outside the concentration cylinder 26 to regulate the temperature inside the concentration cylinder 26. The temperature controller 29 is located below the vacuum pump 28, and a conduit 30 is fixedly connected to the output end of the temperature controller 29. The conduit 30 changes the temperature of the material inside the concentration cylinder 26 through heat conduction, thereby optimizing the concentration effect. The conduit 30 extends through the interior of the concentration cylinder 26.
[0030] Working principle: At the start of filtration, the material enters the upper half 1 of the filter cylinder through the feed inlet 12 and is first intercepted by the coarse screen 9, removing large particles. The coarse screen 9 is embedded with an annular screen cylinder 10, through which smaller particles are further screened using multiple diamond-shaped screen holes 11. The screening by the annular screen cylinder 10 improves screening efficiency, reduces clogging, and ensures material flowability and filtration effect.
[0031] Next, the rotating disk 5 inside the upper half 1 of the filter cylinder is driven by the filter motor 3, which in turn drives the anti-clogging column 6 to rotate. When clogging occurs during the filtration process, the rotation of the anti-clogging column 6 effectively promotes the separation of materials, preventing material deposition and maintaining material flowability. To enhance the mixing and flowability of materials during filtration, a movable ring 7 is connected to the anti-clogging column 6. The movable ring 7 can rotate within a certain range, and multiple blades 8 are fixedly connected to its outer wall. Through the mixing action of the blades 8, the uniform distribution of materials is improved, thereby enhancing the filtration efficiency. At the same time, the electrophoresis ring 15 in the lower half 2 of the filter cylinder works in conjunction with the ring motor 14 to adsorb tiny impurities through the action of an electric field, further improving the filtration effect. Finally, the activated carbon layer 16 inside the lower half 2 of the filter cylinder adsorbs odors, pigments, or other impurities in the filtered material, ensuring the purification effect of the material.
[0032] To facilitate equipment inspection, maintenance, and cleaning, the upper half 1 and lower half 2 of the filter cylinder are connected by a hinge 19, which is fixed to the bottom rear outer wall of the upper half 1. The hinge 19 design allows operators to easily separate the upper half 1 from the lower half 2. Whenever equipment inspection or cleaning is required, operators simply loosen the connection to open the upper and lower halves of the filter cylinder. Once opened, personnel can easily enter to check the filter's operation or perform maintenance and cleaning of the internal components.
[0033] When closed, the upper and lower halves of the filter cylinder are securely connected via an upper connecting plate 23, a lower fixing plate 20, a locking plate 21, a pin 22, and a locking ring 24. The pin 22 passes through the upper connecting plate 23 and the locking plate 21, and is secured by the locking ring 24, ensuring a tight connection between the upper half 1 and the lower half 2 of the filter cylinder during filtration, preventing loosening or separation. The structural design of the upper connecting plate 23 and the lower fixing plate 20 ensures the stability of the equipment, effectively preventing loosening of the upper and lower parts during operation, thus ensuring the smooth operation of the entire filtration process.
