[0024] Specifically, the staff will start the dust suction fan 4, and a negative pressure is formed in the dust suction pipe 5 and the connecting pipe 12, which are connected by the connecting block 15. During the dust collection operation, the threaded connection can be performed. The dust suction nozzle 7 is connected to the dust suction fan 4 through the dust suction pipe 5 and the connecting pipe 12. The external dust-containing air can be sucked into the dust suction nozzle 7 under the action of negative pressure, and then transported to the collection box 1 through the dust suction pipe 5 and the connecting pipe 12. The winding roller 8 is used to store the dust suction pipe 5. The winding roller 8 can be wound and unwound by rotating the handle 9. The fixed block two 26 can fix the other end of the dust suction pipe 5 to avoid the phenomenon of rolling off. The handle 9 is used for manual operation of the rotation of the winding roller 8, which facilitates the adjustment of the length and position of the dust suction pipe 5. The dust collection bag 14 installed on both sides of the collection box 1 can collect dust. The push handle 3 facilitates the movement of the entire collector. The dust suction pipe 2 is connected to the collection box 1. The motor 16 drives the screening device to rotate, and the screening device screens the dust-containing air entering the collection box 1.

[0025] The dust suction nozzle 7 can effectively suck the dust generated in the cement production process into the collection box 1. The design of the winding roller 8 can flexibly adjust the length and position of the dust suction pipe 5, adapt to different dust collection scenes, and solve the problem of poor dust collection effect in cement production. Through reasonable structural design, the dust suction pipe 5 is convenient to operate and manage, and the flexibility of dust collection is improved.

[0026] Referring to Figure 1 、 Figure 2 , the screening device comprises a rotating shaft one 19, the output end of the motor 16 is fixedly arranged at one end of the rotating shaft one 19, the two sides of the middle part of the rotating shaft one 19 are rotatably connected with the fixed block one 18, and the two ends of the rotating shaft one 19 are provided with eccentric wheels 20; the top end of the fixed block one 18 is fixedly connected with the filter plate three 25, and the two ends of the filter plate three 25 are arranged on the inner wall of the collection box 1; the two sides of the upper surface of the filter plate three 25 are provided with springs two 24, the top end of the spring two 24 is provided with a filter plate two 23, the two sides of the upper surface of the filter plate two 23 are provided with springs one 22, the top end of the spring one 22 is provided with a filter plate one 21, and the filter plate one 21 and the filter plate two 23 are arranged in the collection box 1; the inner wall of the collection box 1 is provided with a dust collecting hopper; the inner wall bottom end of the collection box 1 is slidably connected with a dust box 13, one side of the dust box 13 is provided with a handle 10, and the dust box 13 is located below the dust collecting hopper; the bottom end of the collection box 1 is provided with universal wheels 11.

[0027] Specifically, the motor 16 is started to drive the rotating shaft 19 to rotate, and the eccentric wheels 20 at both ends of the rotating shaft 19 generate centrifugal force and vibration during rotation. The vibration is transmitted to the filter plate three 25 through the fixed block one 18, and the filter plate three 25 vibrates to drive the filter plate two 23 to vibrate through the spring two 24, and the filter plate two 23 drives the filter plate one 21 to vibrate through the spring one 22. During the screening process, the dust filtered out falls through each layer of filter plate under the action of gravity, and the dust falls into the dust hopper through the vibration screening, and then slides into the dust box 13 from the dust hopper. The dust box 13 can be conveniently pulled out from the bottom of the collection box 1 through the handle 10 for recycling. The universal wheel 11 can rotate flexibly in all directions, and the universal wheel 11 enables the collection box 1 to move freely on the cement production site when the operator pushes the collection box 1 through the push handle 3.

[0028] The filter plate one 21, the filter plate two 23 and the filter plate three 25 screen the dust-containing air entering the collection box 1 from the communication pipe 2 under the action of vibration. The dust after screening is concentrated and collected, and the dust of different particle sizes is stratified and filtered during vibration according to the particle size. The screened cement dust can be recycled. The problem that the dust is difficult to separate after being collected is solved, and the dust is preliminarily classified through the multi-layer vibration filter plate, thereby improving the efficiency and recovery rate of dust treatment.

[0029] Working principle: when working, the dust suction fan 4 is started to suck the dust in the cement production environment through the dust suction pipe 5 and the dust suction nozzle 7. The winding roller 8 on the outer wall of the dust suction pipe 5 can be adjusted in length through the rotating handle 9 for convenient operation. The dust-containing air enters the inside of the collection box 1 through the communication pipe 2. The motor 16 drives the screening device to operate, and the core is that the rotating shaft one 19 drives the eccentric wheel 20 to rotate to make the fixed block one 18 vibrate, and then drive the filter plate three 25 to vibrate. The filter plate three 25 drives the filter plate two 23 to vibrate through the spring two 24, and the filter plate two 23 drives the filter plate one 21 to vibrate through the spring one 22. The multi-layer filter plate screens the dust, and the dust of different particle sizes is stratified and filtered. The filtered dust falls into the dust hopper under the action of gravity, and finally enters the dust box 13. The dust box 13 can be pulled out for cleaning through the handle 10, and the entire collector can be conveniently moved through the universal wheel 11 and the push handle 3.
