The device includes a purification chamber shell, a filter media shell fixedly connected inside the purification chamber shell, an adsorption ball filter box movably connected inside the filter media shell, a transmission assembly on the outside of the filter media shell, and a discharge assembly located below the outside of the filter media shell. The discharge assembly includes a through pipe and a discharge pipe, and a dispersing assembly for dispersing the adsorption balls is located inside the discharge pipe.

Description

Technical Field

[0001] This invention relates to the field of separation technology, and in particular to a dust air purification device for factory use. Background Technology

[0002] During factory production, industrial dust is usually treated using dry purification technology. A common method is to use activated adsorption materials to adsorb and filter particulate matter and harmful substances in the airflow. In order to improve purification efficiency, a large number of adsorption balls are often filled into the purification equipment to increase the contact area. However, since the treated airflow is usually at a high temperature and may carry moisture, the adsorption balls will not only become saturated and fail during continuous operation, but also easily become sticky due to moisture. This phenomenon seriously affects the smooth discharge and replacement of saturated adsorption balls, which in turn leads to a decrease in purification efficiency, maintenance difficulties, and even affects the continuous and stable operation of the system. Summary of the Invention

[0006] As a preferred embodiment of the present invention, the dispersing assembly includes two blades for contacting the adsorption ball, a base plate for placing the two blades, and a vertical post. The base plate is fixedly connected to the lower end of the vertical post. Hollow slots are provided on both sides of the outer side of the vertical post.

[0007] As a preferred technical solution of the present invention, a transmission assembly is provided on the outside of the transverse transmission toothed plate and connected to the bottom plate.

[0008] Compared with the prior art, the beneficial effects that this invention can achieve are: By setting up a transmission component in conjunction with a dispersing component and a transmission component, the transmission component drives the adsorption ball filter box to rotate inside the filter media shell. When the adsorption ball filter box rotates, it works with the blades in the dispersing component to make the adsorption balls contact the blades. The blades then disperse the adsorption balls that are stuck together, ensuring the normal discharge of the saturated adsorption balls and achieving the effect of quickly dispersing the adsorption balls and discharging them into the adsorption ball collection box.

[0009] By setting up a transmission component in conjunction with the discharge component, the adsorption balls stored inside the adsorption ball filter box fall and are discharged into the adsorption ball collection box. At the same time, when the side plate in the discharge component moves, the limiting rod is set to make the side plate move laterally more stably outside the discharge pipe. As the side plate moves, it drives the limiting rod to stretch, and with the reset rotation of the active gear, it stably drives the side plate and the baffle to close the inside of the discharge pipe again, achieving the effect of stably opening or closing the inside of the discharge pipe.

[0010] The transmission assembly resets the side plate and baffle, closing the inside of the feed pipe. At the same time, the transmission assembly drives the dispersing assembly to retract into the feed pipe. The blade in the transmission assembly falls back into the empty slot under gravity, and the blade drives the pull rope to reset the rocker plate, thus achieving the effect of dispersing the adsorption balls by reciprocating.

A rotating seat 59 is fixedly connected to the exterior of each blade 57. A rotating shaft 58 is fixedly connected inside the rotating seat 59. The rotating shaft 58 is rotatably connected inside the groove 56. The blades 57 rotate within the groove 56 via the rotating seat 59 and the rotating shaft 58.

The stop plate 510 is fixedly connected to the inner wall of the feed pipe 21.

[0017] A transmission assembly is provided on the outside of the transverse transmission gear plate 26 and connected to the base plate 50. The transmission assembly includes a drive motor 30, an active gear 31, a vertical gear plate 32, and a vertical slot 33. The drive motor 30 is fixedly connected to the inner wall of the purification chamber shell 10. The active gear 31 is fixedly connected to the outside of the output shaft of the drive motor 30. The active gear 31 and the transverse transmission gear plate 26 are meshed. The vertical slot 33 is opened on the outside of the feed pipe 21. The vertical gear plate 32 is movably connected to the inside of the vertical slot 33. Both sides of the outside of the vertical gear plate 32 are provided with protrusions. Both sides of the inside of the vertical slot 33 are provided with long slots that are adapted to the width of the protrusions of the vertical gear plate 32. The vertical gear plate 32 is fixedly connected to the outside of the base plate 50. The base plate 50 moves stably upward or downward inside the feed pipe 21 through the vertical gear plate 32 and the vertical slot 33. The vertical gear plate 32 and the active gear 31 are meshed.

[0018] Working principle: The first step is to guide the flue gas through the feed pipe 13 into the adsorption ball filter box 17, where it is adsorbed by the adsorption balls stacked inside the adsorption ball filter box 17.

[0019] In the second step, after the adsorption balls are saturated with the flue gas, the drive motor 30 is started to drive the active gear 31 to mesh with the transverse transmission gear plate 26. The transverse transmission gear plate 26 is driven by the active gear 31 to move inside the slide 29. At the same time, the transverse transmission gear plate 26 drives the short plate 27 to pull the side plate 23 away from the outer slot 25. The side plate 23 drives the baffle 28 to move away from the inside of the feed pipe 21. At this time, the inside of the feed pipe 21 opens to allow the adsorption balls stored in the adsorption ball filter box 17 to fall and be discharged into the adsorption ball collection box 15. At the same time, when the side plate 23 moves, the limiting rod 24 is set to make the side plate 23 move more stably outside the feed pipe 21. When the side plate 23 moves, it drives the limiting rod 24 to stretch, and with the reset rotation of the active gear 31, it stably drives the side plate 23 and the baffle 28 to close the inside of the feed pipe 21 again, achieving the effect of stably opening or closing the inside of the feed pipe 21.

[0020] The third step involves rotating the active gear 31 to engage the vertical gear plate 32, which in turn drives the base plate 50 to move upward inside the feed pipe 21. Simultaneously, as the base plate 50 moves the vertical post 51 upward, the baffle 28 separates from the feed pipe 21. The upward movement of the vertical post 51 causes the pull rope 54 to contact the abutment plate 510. At the same time, the upper part of the vertical post 51 passes through the through pipe 20 and enters the adsorption ball filter box 17. The abutment plate 510 pushes the rocker plate 53, pulling the pull rope 54 and causing the rotating seat 59 to rotate around the shaft 58 in the air. The trough 56 rotates inside, and the rotating seat 59 rotates, causing the blade 57 to open inside the adsorption ball filter box 17. At this time, the rotary motor 42 drives the driven gear 44 to mesh with the sleeve gear 41. The sleeve gear 41 drives the transmission sleeve plate 40 to rotate inside the bearing 43, causing the adsorption ball filter box 17 to rotate inside the filter media shell 16. The rotation of the adsorption ball filter box 17 causes the adsorption balls to rotate synchronously and come into contact with the blade 57. The blade 57 breaks up the adsorbed adsorption balls, achieving the effect of quickly dispersing the adsorption balls into the adsorption ball collection box 15 for discharge.

[0021] The fourth step involves discharging the adsorption balls inside the adsorption ball filter box 17, and then using the switch valve 12 to open the adsorption ball feeding tank 11 to add new adsorption balls into the adsorption ball filter box 17 for use.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
