[0037] Working principle: Place the device at the place of use, turn on the dust suction fan 5 and the spray head 24, so as to absorb the dust generated by the quartz sand production, and the dust enters the storage box 2 through the dust cover 20, the connecting block 19, the rotating shaft 3 17, the dust suction pipe 1 22 and the dust suction pipe 2 23. The water sprayed by the spray head 24 removes the dust and makes it fall on the filter 6. The water is discharged through the drain pipe 37 for recycling. When too much dust falls on the filter 6 under the action of the spray head 24, the water permeable holes on the filter 6 are blocked, affecting the circulation of the water, the dust suction fan 5 and the spray head 24 are stopped, and the water is discharged through the drain pipe 37. When water stops flowing out, the sealing door 36 is opened and the filter screen 6 is pressed. The filter screen 6 drives the connecting barrel 31 to move. The movement of the connecting barrel 31 drives the sliding rod 32 and the locking block 33 to move. The locking block 33 moves into the second through hole under the obstruction of the slider 30, so that the locking block 33 slides along the slider 30 to between the slider 30 and the fixed block 1 28. Then the filter screen 6 is released and the filter screen 6 moves upward under the action of the second spring 35. The upward movement of the filter screen 6 drives the connecting barrel 31 to move. The movement of the connecting barrel 31 drives the locking block 33 to move. The movement of the locking block 33 drives the slider 30 to move, so that the slider 30 and the fixed block 2 29 are locked. The locking block 33 is matched, so that the locking block 33 moves along the arc of the slider 30, so that the locking block 33 moves to the top of the fixed block 29, so that the filter 6 is removed for cleaning (the slider 30 is restored to the accident state under the influence of gravity, that is, the slider 30 is in contact with the fixed block 1 28), and the cleaned dust is uniformly processed, thereby avoiding the quartz dust generated in the quartz sand production process from floating in the working environment to pollute the working environment, and then causing the staff to inhale the quartz dust to cause damage to the human respiratory system, thereby affecting the health of the staff. When the filter 6 is cleaned, the connecting barrel on the filter 6 is removed. 31 is put on the fixing column 1 26, the fixing column 2 27, the fixing block 1 28 and the fixing block 2 29, and pressed. The filter screen 6 drives the connecting barrel 31 to move. The movement of the connecting barrel 31 drives the sliding rod 32 and the locking block 33. The locking block 33 moves along the edge of the fixing block 29 to the lower surface of the fixing block 29. The locking block 33 stretches under the action of the spring 1 34, thereby locking it. After closing the sealing door 36, the dust collection work can be carried out, avoiding the spray water from not being recycled or the long-term use of unfiltered spray water, which increases the friction on the impeller on the spray pump, thereby reducing the service life of the spray pump;When dust is removed at other angles according to the needs, start motor 17 or motor 2 8, the output shaft of motor 17 drives worm 19 to rotate, the rotation of worm 19 drives worm wheel 14 to rotate, the rotation of worm wheel 14 drives shaft 11 to rotate, the rotation of shaft 11 drives bevel gear 16 to rotate, the rotation of bevel gear 16 drives bevel gear 2 18 to rotate, the rotation of bevel gear 2 18 drives shaft 3 17 to rotate, the rotation of shaft 3 17 drives connecting block 19 to rotate, the rotation of connecting block 19 drives dust cover 20 (front and back) to rotate, the output shaft of motor 2 8 drives worm 2 10 to rotate, the rotation of worm 2 10 drives worm wheel 2 15 to rotate, and the rotation of worm 2 The rotation of wheel 2 15 drives shaft 2 13 , which in turn drives rotating block 12 , which in turn drives dust hood 20 to rotate (left and right). The coordinated use of motor 1 7 and motor 2 8 allows for multiple angle adjustments based on dust removal requirements, thereby increasing the flexibility of the dust removal angle and facilitating dust removal in areas where quartz dust generated during the quartz sand production process accumulates. This process can be achieved without adjusting the overall angle of the equipment, nor does it require stopping the dust extraction fan 5 , thereby ensuring continuous operation of the dust extraction fan 5 and avoiding the manpower required to adjust the overall equipment.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
