A discharge pipe 10 is fixedly installed at the position corresponding to the filter port 5 on the side wall. It should be noted that the rotation of the bottom plate 7 is controlled by the driving assembly 9. When the bottom plate 7 rotates, it drives the three filter screens 8 to rotate inside the arc groove 6. The filter screen 8 with a suitable mesh size is selected to stay at the position of the filter port 5. When the raw materials inside the kettle body 1 enter the filter cover 2 through the feed hole 4, they will continue to pass through the filter screen 8 staying at the filter port 5, and then enter the inside of the discharge pipe 10. The filtered raw materials are then discharged through the discharge pipe 10. The staff only needs to select the filter screen 8 with a suitable mesh size according to the raw materials inside the kettle body 1.

[0023] like Figures 1 to 3 As shown, the driving assembly 9 includes two cylinders 901, and the two cylinders 901 are fixedly installed on the bottom of the kettle body 1, and the output ends of the two cylinders 901 are jointly fixedly installed with a mounting rod 902, and the top of the mounting rod 902 is fixedly installed with a servo motor 903. It should be noted that when the two cylinders 901 are started, they can jointly drive the mounting rod 902 to move downward, and the mounting rod 902 drives the servo motor 903 to move downward, and the servo motor 903 drives the bottom plate 7 to move downward, and the bottom plate 7 drives the three filter screens 8 to detach from the inside of the arc groove 6, and the servo motor 903 can drive the bottom plate 7 to rotate when it is started.

[0024] like Figure 2 , Figure 3 As shown, a connecting block 11 is fixedly installed at the bottom of the base plate 7, and a circular sleeve 12 is fixedly installed at the output end of the servo motor 903. Two threaded holes 13 are provided on the side wall of the circular sleeve 12. A bolt 14 is threadedly connected inside each threaded hole 13. It should be noted that by rotating the two bolts 14, the two bolts 14 are close to each other to clamp the connecting block 11. If the two bolts 14 are away from each other, the connecting block 11 can be loosened and taken out from the circular sleeve 12, so as to facilitate the dumping of impurities located on the top of the base plate 7.

It should be noted that when the connecting block 11 is placed inside the circular sleeve 12, the two slide bars 18 are respectively located inside the two slide grooves 17, so as to limit the position of the connecting block 11 installed inside the circular sleeve 12, and ensure that the two clamping blocks 16 can respectively enter the inside of the two clamping grooves 15 when they are close to each other.

[0027] like Figure 1 As shown, the inner bottom surface of the discharge pipe 10 is in an inclined state, the highest end of the inner bottom surface of the discharge pipe 10 is the side close to the filter cover 2, and the lowest end of the inner bottom surface of the discharge pipe 10 is the side away from the filter cover 2. It should be noted that when the raw material enters the interior of the discharge pipe 10, the inner bottom surface of the discharge pipe 10 is in an inclined state, which can make it easier to discharge the raw material.

[0028] In summary:

[0029] The bottom plate 7 is controlled to rotate by the driving assembly 9. When the bottom plate 7 rotates, it drives the three filter screens 8 to rotate inside the arc groove 6. The filter screen 8 with a suitable mesh size is selected to stay at the position of the filter port 5. When the raw materials inside the kettle body 1 enter the filter cover 2 through the feed hole 4, they will continue to pass through the filter screen 8 staying at the filter port 5, and then enter the inside of the discharge pipe 10. The filtered raw materials are then discharged through the discharge pipe 10. The staff only needs to select the filter screen 8 with a suitable mesh size according to the raw materials inside the kettle body 1.
