The first end cover 402 and the second end cover 403 are respectively installed on the left and right ends of the centrifugal filter cylinder 401. The connecting shaft disc 404 is installed on the side of the first end cover 402 away from the centrifugal filter cylinder 401, and the metering valve 405 is installed on the side of the second end cover 403 away from the centrifugal filter cylinder 401. The power output end of the servo motor 203 is connected to the connecting shaft disc 404, and one end of the rotary joint 303 is connected to the metering valve 405. 05 are interconnected. The drive component 2 includes a first cover 201, a stabilizer 202, and a servo motor 203. The stabilizer 202 is installed in the middle of the side surface of the first cover 201 away from the filter vessel 1, and the servo motor 203 is horizontally installed in the middle of the stabilizer 202. The first cover 201 and one end of the main vessel 101 are connected to each other by a flange structure, and the stabilizer 202 and the first cover 201 are movably connected. The power output end of the servo motor 203 is connected to one end of the main vessel 101 through a sealed bearing seat. The centrifugal filter cartridge 401 is connected to the power output end of the servo motor 203 by a connecting shaft disc 404 on one side of the first end cover 402. Under the operation of the servo motor 203, the filter component 4 will be driven to rotate rapidly inside the filter vessel 1.

[0026] like Figures 1 to 6As shown, the filter vessel 1 includes a main vessel body 101, a docking seat 102, a control valve 103, and an external connecting pipe 104. The docking seats 102 are symmetrically arranged on the bottom of the main vessel body 101, and the control valve 103 is installed at the bottom of the docking seat 102. The bottom of the control valve 103 is connected to the external connecting pipe 104. The docking seats 102 and the main vessel body 101 are integrally formed, and the control valve 103 is movably connected to the docking seat 102. The control valve 103 and the external connecting pipe 104 are also integrally formed. The feeding assembly 3 includes a second cover 301, a fixed seal 302, and a rotary joint 303.

The entire filter component 4, which is connected to the servo motor 203 via the connecting shaft disk 404 on one side of the first end cover 402, will rotate horizontally inside the filter vessel 1, thereby starting the filtration process using the centrifugal force of rotation.

[0029] The filtered material is thrown onto the inner wall surface of the main vessel 101 and then flows into the control valve 103 at the bottom of the docking seat 102. Under the operation of the control valve 103, the external pipe 104 is connected to the lower equipment, so that the filtered material is transported to the lower equipment for further processing. Then, during the rotation of the entire filter component 4, the structure of the rotary joint 303 can provide material to the inside of the filter component 4 in real time, thereby realizing continuous processing.
