After cleaning, the sewage is discharged through the outlet pipe 303, and then the motor 703 drives the rotating rod 7 to rotate at a high speed, so that the opening and closing support plate 5 drives the rotating net cylinder 4 to rotate at a high speed, and the water is thrown out under the centrifugal action, which is beneficial to the rapid drainage of the raw materials and improves the cleaning efficiency. At this time, the internal threaded cylinder 601 disengages from the threaded section 701 upward and elastically squeezes the second spring 605, so that the push cylinder 6 remains stationary.

[0041] When drying, the motor 703 drives the rotating rod 7 to reverse, and the internal threaded cylinder 601 moves downward along the threaded section 701, driving the push cylinder 6 to push the opening and closing support plate 5 downward, and the opening and closing support plate 5 drives the positioning strip 504 to disengage from the positioning groove 702 of the rotating rod 7, so that the opening and closing support plate 5 is released from the restriction with the rotating rod 7, so that the opening and closing support plate 5 opens the bottom of the rotating mesh cylinder 4 to unload the material into the drying box 2, and the raw material falls onto the inclined mesh plate 8, and the heater 202 is started to heat and dry the raw material on the inclined mesh plate 8.

[0042] When uniform drying is carried out, the above operation is performed, and the opening and closing support plate 5 is moved downward and reset upward reciprocatingly, which can drive one side of the inclined mesh plate 8 to move up and down, and then drive the inclined mesh plate 8 to swing left and right, so that the raw materials on the inclined mesh plate 8 roll and shake left and right, which is convenient for the raw materials to be evenly spread on the inclined mesh plate 8 and to be dried comprehensively in all directions. The drying effect is sufficient and fast, which effectively improves the drying efficiency, thereby facilitating the improvement of subsequent processing quality and work efficiency.
