A rotating rod is rotatably installed on the inner surface of the connecting pipe. A slot is formed inside the rotating rod. A second rotating rod is fixedly inserted through the surface of the first rotating rod. An air outlet is fixedly inserted through the surface of the second rotating rod. A slot is formed inside the second rotating rod. The rotation of the second rotating rod drives the first rotating rod to rotate, causing the second rotating rod to stir in the liquid. The more gas enters the liquid, the faster the stirring rate, and the stronger the contact time between the gas and the liquid, the stronger the ability to dissolve dust in the air.

A connecting ring is fixedly mounted on the end of the connecting rod one away from the sliding plate. A circular ring is fixedly mounted at the center of the connecting ring. The stirring device causes the activated carbon particles inside the activated carbon plate shell to turn over by rotating the stirring rod, so that the contact time with the gas after liquid filtration is longer and the contact opportunities are more numerous, so that the stirring rod can fully stir the activated carbon particles in every place.

[0011] Preferably, the output end of the motor rotates through the top of the support frame, and the activated carbon plate shell is slidably mounted on the inner surface of the outer shell.

[0012] Preferably, the connecting ring is slidably mounted on the inner surface of the housing, the inner surface of the ring is provided with a thread, the upper half of the rotating rod is provided with a bidirectional thread, the thread engages with the bidirectional thread, the rotating rod rotates to drive the ring to rotate, the rotating rod engages with the thread on the inner surface of the ring, the rotation of the ring drives the connecting ring to move upward, and the upward movement of the connecting ring drives the connecting rod to move upward.

[0015] This invention provides an air dust removal device for grain processing and drying workshops. It has the following beneficial effects:

[0016] (1) The dust removal device of this equipment achieves the dust removal effect by introducing air from the grain processing and drying workshop into the liquid. The gas enters the liquid from the side of the stirring rod and generates thrust, which causes the rotating rod to stir in the liquid. The more gas enters the liquid, the faster the stirring rate, and the longer the contact time between the gas and the liquid. The stronger the ability to dissolve dust in the air, the higher the dust removal efficiency. Continuous stirring can also effectively prevent dust in the liquid from settling and clumping, thus reducing the difficulty of manual cleaning.

[0017] (2) The stirring device of the equipment rotates the stirring rod, which makes the activated carbon particles inside the activated carbon plate shell turn over, so that they have a longer contact time with the gas after liquid filtration and more contact opportunities. The rotation of the nozzle makes the water mist sprayed by the liquid fully distributed inside the equipment, capturing the remaining dust in the air and improving the dust purification effect. When the rotating rod rotates, the connecting ring moves up and down. While stirring the liquid, it drives the sliding plate to move up and down to impact the activated carbon plate shell, so that the stirring rod can fully stir the activated carbon particles in every place. The vibration generated by the impact can also make the activated carbon particles vibrate, improve the purification efficiency of the activated carbon particles, further improve the quality of the exhaust air, and protect the health of workers.

[0018] (3) The water level control device of the equipment can control the height of the water level in the equipment. The floating ring moves up and down with the water level. When the water level reaches a certain height, the baffle two moves upward to discharge the liquid in the equipment. At the same time, the nozzle continuously sprays the liquid, which reduces the dust content in the liquid and improves the dust dissolution efficiency. The discharged liquid enters the filter tank and separates the grain dust from the liquid through the filter screen, which facilitates the recycling of grain dust. While stirring, the stirring rod collides with the connecting rod three to drive the filter plate to vibrate, preventing the filter plate from clogging and reducing the filtration efficiency.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 One embodiment of the present invention is: an air dust removal device for a grain processing and drying workshop, including a shell 1, a support frame 2 fixedly installed on the top of the shell 1, and also including a dust removal device, a stirring device and a water level control device;

[0029] The dust removal device includes an air inlet 301, which is fixedly installed through the surface of the outer shell 1. A connecting pipe 302 is fixedly installed at one end of the air inlet 301. A rotating rod 303 is rotatably installed on the inner surface of the connecting pipe 302. A slot 304 is opened inside the rotating rod 303. A rotating rod 305 is fixedly installed through the surface of the rotating rod 303. An air outlet 306 is fixedly installed through the surface of the rotating rod 305. A slot 307 is opened inside the rotating rod 305. The air outlet 306 is fixedly installed on the side of the rotating rod 305. The rotating rod 303 is rotatably installed inside the outer shell 1. The gas discharged from the air outlet 306 interacts with the liquid to generate thrust, which drives the rotating rod 305 to rotate.

[0030] The connecting pipe 302 has an air inlet groove inside, the air inlet 301 is connected to the air inlet groove, and the air inlet groove is connected to the slot 304 opened inside the rotating rod 303.

[0031] Rotating rod 303 is rotatably mounted on the inner surface of housing 1. Slot 304 is connected to slot 307, and vent 306 is connected to slot 307. Rotating rod 305 stirs the liquid. The more gas enters the liquid, the faster the stirring rate.

[0032] In this embodiment, during operation: The air inlet 301 introduces polluted gas drawn in from the grain processing and drying workshop. The polluted gas enters the connecting pipe 302, which has an air inlet slot. The air inlet 301 communicates with the air inlet slot, which is connected to a slot 304 inside the rotating rod 303. The polluted gas then enters the rotating rod 305. The air outlet 306 connects to a slot 307 inside the rotating rod 305, allowing the polluted gas to enter the liquid inside the equipment through the air outlet 306. Since the air outlet 306 is fixedly installed on the side of the rotating rod 305... Furthermore, the rotating rod 303 is rotatably installed inside the outer casing 1. The gas discharged from the vent 306 interacts with the liquid to generate thrust, driving the rotating rod 305 to rotate. The rotation of the rotating rod 305 drives the rotating rod 303 to rotate, causing the rotating rod 305 to stir in the liquid. The more gas enters the liquid, the faster the stirring rate, and the stronger the contact time between the gas and the liquid. This enhances the ability to dissolve dust in the air, improving dust removal efficiency. Continuous stirring also effectively prevents dust in the liquid from settling and clumping, thus reducing the difficulty of manual cleaning.

[0033] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the stirring device includes a motor 401, which is fixedly installed on the top of the support frame 2. A rotating rod 402 is fixedly installed at the output end of the motor 401. An activated carbon plate shell 403 is slidably installed on the outer surface of the rotating rod 402. A placement groove 404 is opened inside the activated carbon plate shell 403. A stirring rod 405 is fixedly installed on the outer surface of the rotating rod 402. A nozzle 406 is fixedly installed at the end of the rotating rod 402 away from the motor 401. A sliding plate 407 is slidably installed on the outer surface of the rotating rod 402. A connecting rod 408 is fixedly installed on the lower surface of the sliding plate 407. A connecting ring 409 is fixedly installed at the end of the connecting rod 408 away from the sliding plate 407. A circular ring 410 is fixedly installed at the center of the connecting ring 409. The rotation of the rotating rod 402 drives the nozzle 406 to rotate, so that the rotation of the nozzle 406 makes the water mist sprayed from the liquid fully distributed inside the device and captures the remaining dust in the air.

[0034] The output end of the motor 401 rotates through the top of the support frame 2, and the activated carbon plate shell 403 is slidably installed on the inner surface of the outer shell 1. The stirring device rotates the stirring rod 405 to make the activated carbon particles inside the activated carbon plate shell 403 turn over, so that the contact time with the gas after liquid filtration is longer and the contact opportunities are more numerous.

[0035] The connecting ring 409 is slidably mounted on the inner surface of the outer casing 1. The inner surface of the ring 410 is provided with threads, and the upper half of the rotating rod 303 is provided with bidirectional threads. The threads mesh with the bidirectional threads. The rotation of the ring 410 drives the connecting ring 409 to move upward. The upward movement of the connecting ring 409 drives the connecting rod 408 to move upward. The upward movement of the connecting rod 408 drives the sliding plate 407 to move upward. The upward movement of the sliding plate 407 and its impact with the activated carbon shell 403 cause the activated carbon shell 403 to move upward. Due to the different rates at which the gas enters through the air inlet 301, the rotation rate of the rotating rod 303 is different, and therefore the frequency of the impact between the sliding plate 407 and the activated carbon shell 403 is also different.

[0036] In this embodiment, during operation: Motor 401 starts working, and its output end begins to rotate. The rotation of Motor 401 drives Rotor 3 402 to rotate, which in turn drives Stirring Rod 405 to rotate. Rotor 3 402 then drives Spray No. 406 to rotate, ensuring that the water mist sprayed from Spray No. 406 is fully distributed inside the equipment, capturing residual dust in the air and improving the dust purification effect. The upper part of Rotor 1 303 is provided with a bidirectional thread. The rotation of Rotor 1 303 drives Ring 410 to rotate. Rotor 1 303 engages with the thread on the inner surface of Ring 410. The rotation of Ring 410 drives Connecting Ring 409 to move upward, which in turn drives Connecting Rod 1 408 to move upward, which in turn drives Sliding Plate 4 The sliding plate 407 moves upward, colliding with the activated carbon shell 403 and causing it to move upward as well. Due to the different rates of gas entering through the air inlet 301, the rotation rate of the rotating rod 303 varies, resulting in different collision frequencies between the sliding plate 407 and the activated carbon shell 403. The faster the air intake rate, the faster the collision frequency; the slower the air intake rate, the slower the collision frequency. The stirring device, through the rotation of the stirring rod 405, causes the activated carbon particles inside the activated carbon shell 403 to tumble, resulting in longer contact time and more contact opportunities with the gas after liquid filtration. This allows the stirring rod 405 to fully stir every activated carbon particle. The vibration generated by the collision also causes the activated carbon particles to vibrate, improving the purification efficiency of the activated carbon particles, further improving the control quality of the discharge, and protecting the health of workers.

[0037] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the water level control device includes a floating ring 501, a connecting rod 502 fixedly mounted on the surface of the floating ring 501, a baffle 503 fixedly mounted on the surface of the connecting rod 502, a limiting groove 504 formed on the surface of the outer shell 1, a baffle 505 fixedly mounted on the end of the connecting rod 502 away from the floating ring 501, a slot 506 formed on the surface of the outer shell 1, a filter tank 507 fixedly mounted on the outer surface of the outer shell 1, a filter plate 508 fixedly mounted on the inner surface of the filter tank 507, a connecting rod 509 fixedly mounted on the side of the filter plate 508, and the baffle 505 moves upward to discharge the liquid in the device while the nozzle 406 continuously sprays the liquid, thereby reducing the dust content in the liquid and improving the dust dissolution efficiency.

[0038] The floating ring 501 is slidably installed on the inner surface of the outer shell 1, the connecting rod 2 502 is slidably installed inside the limiting groove 504, and the connecting rod 3 509 is fixedly installed through the outer shell 1. The bottom of the filter tank 507 is provided with an outlet. When the rotating rod 2 305 rotates, the connecting rod 3 509 will collide with it and generate vibration to prevent the filter plate 508 from being blocked and reducing the filtration efficiency.

[0039] In this embodiment, during operation: the water level inside the equipment increases continuously due to the operation of the nozzle 406. When the water level rises to a certain height, the floating ring 501 moves upward with the rising water level. The upward movement of the floating ring 501 drives the connecting rod 502 to move upward, which in turn drives the baffle 503 to move upward. The upward movement of the connecting rod 502 drives the baffle 505 to move upward, and the liquid begins to slowly flow out from the slot 3 506. Simultaneously, the upward movement of the baffle 505 discharges the liquid from the equipment, and the nozzle 406... 06. Continuously spraying liquid reduces the dust content in the liquid, improves dust dissolution efficiency, and flows into the filter tank 507. The filter plate 508 separates the grain dust from the liquid, facilitating the recovery of the grain dust. The liquid flows into the outside through the outlet at the bottom of the filter tank 507, while the grain dust remains on the upper surface of the filter plate 508. Since the filter plate 508 is fixedly connected to the connecting rod 3 509, and the connecting rod 3 509 will collide with the rotating rod 2 305 to generate vibration, it prevents the filter plate 508 from clogging and reducing the filtration efficiency.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
