The output shaft of the motor 6 is fixedly connected to the right end of the reciprocating screw 39. The input end of the motor 6 is electrically connected to the output end of the controller 11. When the first filter plate 7, the second filter plate 8, and the third filter plate 9 are respectively inserted into the first clearance opening 28, the rear side of the abutment plate 10 can press against the first filter plate 7, the second filter plate 8, and the third filter plate 9. The front side of plate 9 is used to prevent the first filter plate 7, the second filter plate 8, and the third filter plate 9 from shaking. After the device has been running for a period of time, the fan 5 can be stopped. At this time, the controller 11 can be adjusted, the motor 6 can be turned, and the output shaft of the motor 6 can be rotated, thereby driving the reciprocating screw 39 to rotate, which in turn drives the sliding seat 35 to move back and forth in the slide groove 34. When the sliding seat 35 moves to the right side of the slide groove 34, it will push the right side of the angle adjusting frame 31 upward through the connecting rod 36. At this time, the angle adjusting frame 31 will rotate counterclockwise by a specified angle around the central axis of the rotating shaft, thereby driving the three arc plates 33 to rotate counterclockwise by a specified angle around the central axis of the rotating shaft. When the device is on the left, the connecting rod 36 will push the right side of the angle adjustment frame 31 downward. At this time, the angle adjustment frame 31 will rotate clockwise around the central axis of the rotating shaft at a specified angle, which will drive the three arc plates 33 to rotate clockwise around the central axis of the rotating shaft at a specified angle. This will drive the brush 38 to brush the left side of the first filter plate 7, the second filter plate 8, and the third filter plate 9 up and down. The dust brushed off will then flow along the dust collection pipe 24 and the coarse slag dust collection pipe 25. At this time, the controller 11 can be adjusted to operate the two ash discharge valves 26, which will discharge the dust inside the dust collection pipe 24 and the coarse slag dust collection pipe 25 into the corresponding dust collection cloth belt 27. After the dust is collected, the fan 5 can be adjusted to continue the dust removal operation.

[0028] The working principle of the dust removal equipment for the pre-treatment process in the pre-treatment workshop of an oil pressing plant provided by this utility model is as follows: When the dust removal equipment is needed, it can be moved to the designated workstation. At this time, the external impurity removal equipment and crushing equipment are controlled to pre-treat the soybean raw materials for oil pressing. The impurity removal equipment and crushing equipment will generate a large amount of dust. At this time, the appropriate air inlet hopper or air inlet pipe can be selected according to the pre-treatment equipment, and the pre-treated equipment can be connected to this equipment. Then, the pre-treatment equipment can be controlled to carry out the operation. At this time, a large amount of dust will be generated. At this time, the controller 11 can be controlled to operate the fan 5. The fan 5 performs the induced draft operation to form a negative pressure airflow. The airflow enters through the inlet duct 4, then flows along the first filter channel 21, the second filter channel 22, and the third filter channel 23, and is then discharged to the outside of the device through the outlet of the fan 5. Before this, the abutment plate 10 can be rotated, and then the first filter plate 7, the second filter plate 8, and the third filter plate 9 can be inserted into the first clearance opening 28 in sequence. At this time, large particles of impurities in the negative pressure airflow will be blocked by the metal mesh filter plate, smaller particles will be blocked by the fiber filter plate, and fine dust will be blocked by the activated carbon filter plate. After being filtered three times, the negative pressure airflow will be discharged to the outside of the device by the fan 5. After the device has been running for a period of time, it can be stopped. At this time, the controller 11 can be adjusted to operate the fan 5, and the motor 6 will rotate. The output shaft of the motor 6 will rotate, thereby driving the reciprocating screw 39 to rotate, which in turn drives the sliding seat 35 to move back and forth in the slide groove 34. When the sliding seat 35 moves to the right side of the slide groove 34, it will push the right side of the angle adjusting frame 31 upward through the connecting rod 36. At this time, the angle adjusting frame 31 will rotate counterclockwise by a specified angle around the central axis of the rotating shaft, thereby driving the three arc plates 33 to rotate counterclockwise by a specified angle around the central axis of the rotating shaft. When the sliding seat 35 moves to the left side of the slide groove 34, it will push the right side of the angle adjusting frame 31 through the connecting rod 36. Downward, at this time, the angle adjustment frame 31 will rotate clockwise around the central axis of the rotating shaft at a specified angle, which in turn will drive the three arc plates 33 to rotate clockwise around the central axis of the rotating shaft at a specified angle, which in turn will drive the brush 38 to brush the left side of the first filter plate 7, the second filter plate 8 and the third filter plate 9 up and down. At this time, the dust brushed down will flow along the dust collection pipe 24 and the coarse slag dust collection pipe 25. At this time, the controller 11 can be adjusted to operate the two ash discharge valves 26 to discharge the dust inside the dust collection pipe 24 and the coarse slag dust collection pipe 25 into the corresponding dust collection cloth belt 27. After the dust is collected, the fan 5 can be adjusted to continue the dust removal operation.

[0029] It is worth noting that the core chip of the controller 11 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32. The ash discharge valve 26, the fan 5, and the motor 6 can be freely configured according to the actual application scenario. It is recommended that the ash discharge valve 26 be a YJD-16 electric rotary valve, the fan 5 be a C6-46 dust collector fan, and the motor 6 be a 57CM23 stepper motor. The controller 11 controls the operation of the ash discharge valve 26, the fan 5, and the motor 6 using methods commonly used in the prior art.
