The present invention provides a kind of environmental protection dust removal device for chemical safety, which drives the worm and the driving shaft to rotate by starting the driving motor, and the driving shaft drives the rotating drum to rotate through the transmission of the active pulley and the driven pulley, and the rotating drum drives multiple arc blades on the outer side thereof to rotate, and the arc blades exert outward thrust on the dust in the air during rotation so that it can be more fully mixed with water to reduce dust, and at the same time, the worm drives the worm wheel to rotate clockwise through the meshing with the worm wheel, and the worm wheel drives the round rod to perform clockwise circular motion, and the round rod pushes the cross plate to move rightward through the contact with the connecting frame, and the cross plate drives the rotating arm to rotate clockwise around the fixed axis through the connecting rod, and stretches the reset spring, and when the round rod is out of contact with the connecting frame, the cross plate is reset under the action of the reset spring, thereby driving the rotating arm to rotate counterclockwise to reset, and under the inertia of the impact plate, it impacts the filter screen, vibrates the dust inside it, and drives the conical cover to rotate through the rotating drum, so that the dust falls to the bottom of the conical cover in the filter cylinder, so as to prevent the filter screen from being blocked; In the present invention, the environmentally friendly dust removal device for chemical safety, when the dust content in the air is large, will cause the dust to accumulate on the filter screen faster, so that the wind resistance of the air passing through the filter screen is large, that is, the filter screen is subjected to a large upward thrust, thereby increasing the pressure on the pressure sensor and the varistor. When the pressure on the varistor increases, its internal resistance decreases. Since the varistor is connected in series with the water pump and the drive motor, the power of the water pump and the drive motor is increased, thereby increasing the water spray volume, and the rotation speed of the arc blade can be increased to make the dust and water mix better. At the same time, the rotation speed of the worm gear is increased, so that the frequency of the impact plate impacting the filter screen is accelerated, thereby better dust removal is performed.

In the present invention, the environmentally friendly dust removal device for chemical safety can achieve dual dust removal work through the filter screen and water spray mechanism, which greatly improves the dust removal effect and changes the traditional dust removal method. It can also adaptively adjust the dust removal effect and dust removal direction according to the dust content in the air, thereby improving the dust removal efficiency while saving resources and maximizing the utilization of resources.

[0023] When the present invention is in use, the rotating motor 303 is started to drive the fan blade 302 to rotate, so that the air in the hood 301 is discharged from the air outlet, so that the air in the filter cartridge 2 and the dust removal cartridge 1 is discharged through the hood 301, so that negative pressure is generated in the air inlet to suck the external gas into the dust removal cartridge 1, and the water supply pipe is connected to the external tap water pipe, and the upper electric control valve 405 is opened and the lower electric control valve 405 is closed, and then the water pump 401 is started to introduce water into the outer annular pipe 402 and the inner annular pipe 403, and spray it out from the multiple nozzles at the bottom to mix it with the dust in the air to achieve the effect of dust reduction, and then the dust enters the filter cartridge 2 through the rotating drum 6 and is filtered by the filter screen 15 to achieve further dust removal; The servo motor 704 is started to drive the driving gear 703 to rotate, and the driving gear 703 drives the rotating ring 7 to rotate by meshing with the inner gear ring 702, thereby continuously changing the direction of the air inlet hole to achieve air extraction and dust removal in different directions. By starting the driving motor 8 to drive the worm 801 and the driving shaft 802 to rotate, the driving shaft 802 drives the rotating drum 6 to rotate through the transmission of the active pulley 803 and the driven pulley 602, and the rotating drum 6 drives the multiple arc blades 601 on the outside thereof to rotate. When rotating, the arc blades 601 apply an outward thrust to the dust in the air so that it is more fully mixed with water to reduce dust. At the same time, the worm 801 drives the worm wheel 907 to rotate clockwise through the engagement with the worm wheel 907, and the worm wheel 907 drives the round rod 906 to perform a clockwise circular motion. The round rod 906 pushes the connecting frame 905 to push ... The horizontal plate 904 moves to the right, and the horizontal plate 904 drives the rotating arm 901 to rotate clockwise around the fixed axis through the connecting rod 902, and stretches the reset spring 903. When the round rod 906 is out of contact with the connecting frame 905, the horizontal plate 904 is reset under the action of the reset spring 903, thereby driving the rotating arm 901 to rotate counterclockwise to reset, and under the inertia of the impact plate 9, it impacts the filter screen 15, vibrates the dust inside it, and drives the cone cover 603 to rotate through the rotating drum 6, so that the dust falls below the cone cover 603 in the filter drum 2 to prevent the filter screen 15 from being blocked; When the dust content in the air is high, the dust will accumulate on the filter 15 quickly, so that the wind resistance of the air passing through the filter 15 is large, that is, the filter 15 is subjected to a large upward thrust, thereby increasing the pressure on the pressure sensor 16 and the piezoresistor 13. When the pressure on the piezoresistor 13 increases, its internal resistance decreases. Since the piezoresistor 13 is connected in series with the water pump 401 and the drive motor 8, the power of the water pump 401 and the drive motor 8 is increased, thereby increasing the water spraying amount, and the rotation speed of the arc blade 601 can be increased to make the dust and water mix better. At the same time, the rotation speed of the worm gear 907 increases, so that the frequency of the impact plate 9 impacting the filter 15 is accelerated, so as to better remove dust. When the pressure on the pressure sensor 16 increases, the rotation speed of the servo motor 704 is controlled by the controller 10 to decrease, thereby reducing the rotation speed of the rotating ring 7, so that when the air inlet 701 of the rotating ring 7 is facing the direction with a large dust content, the rotation speed of the rotating ring 7 is small, thereby enhancing the dust removal efficiency in the area with a large dust content in the air; By pushing the sealing ring 201 upward, the dust accumulated in the filter cartridge 2 can be cleaned through the cleaning port, and the dust accumulation and sedimentation conditions inside the dust cartridge 1 can be observed through the transparent observation window 104. When the dust is basically precipitated, the upper electric control valve 405 is controlled by the controller 10 to close and the lower electric control valve 405 is controlled to open. At this time, the water pump 401 extracts water from the dust cartridge 1 through the suction pipe 406 to achieve water recycling. Then, when the amount of dust accumulated in the dust cartridge 1 is large enough, the two card plates 503 are pulled out of the card slots to release the fixation of the bottom cover 5, so that the bottom cover 5 can be removed and the dust inside the dust cartridge 1 can be cleaned.
