Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, in particular to an air filtering device for environmental protection engineering. Background Art

[0002] An air filter is a device that captures dust from a gas-solid two-phase flow through porous filter material, purifying the air. It then purifies low-dust air and delivers it to the room, ensuring the cleanliness of cleanroom processes and the air in general air-conditioned rooms. An air filter is an air filtration device, typically used in cleanrooms, cleanrooms, laboratories, and cleanrooms, as well as for dust control in electronic, mechanical, and communication equipment.

[0003] Filtration equipment commonly uses filters to screen impurities from the air. However, as filtration time increases, dust and impurities accumulate on the filter surface, affecting its effectiveness and requiring manual cleaning. When filtering water-soluble impurities, existing filtration equipment typically inserts an air tube directly under clean water. The air from the tube forms bubbles in the clean water, which move upward. These bubbles are large, preventing the air within them from fully contacting the clean water, resulting in poor water dissolution and adsorption of airborne impurities. Summary of the Invention

Opening 111, the top wall of the box body 1 is fixedly installed with a connecting rod 17, the connecting rod 17 is connected to the air inlet pipe 11, the inner side wall of the box body 1 is rotatably installed with a cross column 3, the surface of the cross column 3 is fixedly installed with a filter disc 4, the filter disc 4 passes through the fracture 111, the surface of the filter disc 4 is provided with a uniformly distributed mesh 41, one end of the cross column 3 extends to the outside of the box body 1 and is connected to a motor 31, the inner cavity of the box body 1 is provided with a dust removal mechanism 5 that cooperates with the mesh 41, the dust removal mechanism 5 includes a flushing component 51 and a driving component 52, the flushing component 51 is located in the inner cavity of the box body 1 and is in the process On the outside of the filter disc 4, the drive assembly 52 is connected to the flushing assembly 51. When the filter disc 4 rotates, the drive assembly 52 performs high-pressure flushing on the impurities attached to the surface of the mesh 41 by cooperating with the flushing assembly 51. The bottom wall of the air storage disc 2 is provided with a transmission assembly 19, and the transmission assembly 19 is connected to the cross column 3. When the filter disc 4 rotates, the transmission assembly 19 is used to control the air storage disc 2 to rotate synchronously around its own axis in the inner cavity of the box 1. The bottom wall of the air storage disc 2 is fixedly installed with an air guide pipe 6 at a position deviating from the center of the circle. The top of the air guide pipe 6 is connected to the air storage cavity 21, and the surface of the air guide pipe 6 is provided with a bubble The bubble refinement mechanism 7 includes a stirring rod 71, a horizontal rotation component 72 and a longitudinal rotation component 73. The stirring rod 71 is provided in multiple groups and surrounds the outside of the air duct 6. The horizontal rotation component 72 is located on the surface of the air duct 6 and is connected to the stirring rod 71. The longitudinal rotation component 73 is located on the outside of the air duct 6 and is connected to the horizontal rotation component 72. When the air storage disk 2 drives the air duct 6 and the stirring rod 71 to rotate, the horizontal rotation component 72 is used to control the multiple groups of stirring rods 71 to rotate around the air duct 6, and the longitudinal rotation component 73 is used to control the multiple groups of stirring rods 71 to rotate in the vertical plane.

[0032] An appropriate amount of aqueous solution is injected into the inner cavity of the housing 1 through the water inlet pipe 13. An external air extraction device delivers air into the air inlet pipe 11. As the air flows through the air inlet pipe 11, it passes through the mesh 41 on the surface of the filter disc 4. Impurities adhere to the surface of the mesh 41, and the mesh 41 can effectively filter impurities contained in the air. The air after preliminary filtration flows from the air inlet pipe 11 into the air storage chamber 21. The air in the air storage chamber 21 further flows into the air guide pipe 6. The bottom end of the air guide pipe 6 is inserted into the water. The air is discharged from the bottom end of the air guide pipe 6. The air forms a bubble structure in the aqueous solution and moves upward. The aqueous solution can effectively dissolve and adsorb impurities in the air. The filtered air is discharged through the air outlet pipe 12.

[0033] When filtering air, the motor 31 drives the horizontal column 3 to rotate, thereby driving the filter disc 4 to rotate synchronously within the inner cavity of the housing 1. The bottom of the filter disc 4 is immersed in the aqueous solution, which moistens the mesh 41 on the surface of the filter disc 4. As the filter disc 4 rotates, the mesh 41 in different areas is controlled to move sequentially into the fracture 111 to filter and remove impurities from the air, effectively improving the filtering and impurity removal effect of the mesh 41 on the air. The mesh 41 area with attached impurities rotates to the outside of the fracture 111 and continues to rotate and immerse in the aqueous solution. The aqueous solution can perform a preliminary cleaning treatment on the impurities attached to the mesh 41. The filter disc 4 continues to rotate, and after the mesh 41 area that has been initially cleaned and moistened moves above the water surface, the flushing component 51 and the drive component 52 cooperate with each other to perform high-pressure flushing treatment on the mesh 41 on the surface of the filter disc 4, which can further improve the cleaning effect of the mesh 41. After cleaning, the moistened mesh 41 rotates to the fracture 111 again, which can maintain a continuous and efficient filtering and impurity removal effect on the air flowing in the intake pipe 11.

[0034] When rotating, the horizontal column 3 cooperates with the transmission assembly 19 to control the air storage disk 2 to rotate around its own axis at the bottom of the air inlet pipe 11. The air storage disk 2 drives the air guide tube 6 to rotate synchronously. The bottom end of the air guide tube 6 rotates in the aqueous solution, thereby controlling the discharge of bubbles in different directions within the aqueous solution. When the air guide tube 6 rotates, it drives the stirring rod 71 to rotate synchronously. The horizontal rotation assembly 72 controls the stirring rod 71 to rotate synchronously around the air guide tube 6 while rotating in the aqueous solution. The longitudinal rotation assembly 73 controls the stirring rod 71 to rotate synchronously in the vertical plane while rotating around the air guide tube 6. The stirring rod 71 moves in all directions within the aqueous solution. As the bubbles move upward, the stirring rod 71 can effectively crush larger bubbles. The larger bubbles in the aqueous solution split into batches of smaller bubbles. The air within the bubbles can fully contact the clean water, which can effectively improve the clean water's ability to dissolve and adsorb impurities in the air within the bubbles.

[0035] like Figure 4 、 Figure 6As shown, as a preferred embodiment of the present invention, the transmission assembly 19 includes a bottom gear ring 191 fixedly mounted on the bottom wall of the air storage disk 2, and a fixed gear disc 192 is fixedly mounted on the end of the cross column 3, and the fixed gear disc 192 is meshedly connected with the bottom gear ring 191.

[0036] When the cross column 3 rotates, it drives the fixed gear disc 192 to rotate synchronously. The fixed gear disc 192 is engaged with the bottom gear ring 191 for transmission, which can drive the air storage disc 2 to rotate around its own axis in the inner cavity of the box body 1.

[0037] like Figure 4 、 Figure 8 、 Figure 9 As shown, as a preferred embodiment of the present invention, the flushing component 51 includes a water storage cylinder 511 fixedly installed on the inner wall of the box body 1, one side of the water storage cylinder 511 is set as an open structure, and a water inlet 512 is provided on the surface of the water storage cylinder 511, and a water pipe 513 is provided on the other side of the water storage cylinder 511. A nozzle 514 is provided at one end of the water pipe 513 away from the water storage cylinder 511, and the nozzle 514 is located outside the mesh 41.

[0038] The water storage cylinder 511 is completely immersed in the aqueous solution in the inner cavity of the box body 1, and the aqueous solution is filled into the water storage cylinder 511 through the water inlet 512. When the cross column 3 drives the filter disc 4 to rotate in the inner cavity of the box body 1, the driving component 52 can intermittently pressurize and push the aqueous solution in the water storage cylinder 511. The aqueous solution in the water storage cylinder 511 is pressurized and flows into the water pipe 513 and then is sprayed out by the nozzle 514. The nozzle 514 controls the high-pressure water to spray toward the surface of the mesh 41. The high-pressure water can efficiently clean the impurities attached to the surface of the mesh 41, and the cleaned impurities are deposited at the bottom of the aqueous solution.

[0039] like Figure 4 、 Figure 6 、 Figure 8 、 Figure 9As shown, as a preferred embodiment of the present invention, the driving assembly 52 includes two sets of vertical plates 521 fixedly installed on the bottom wall of the box body 1 and distributed in parallel. The two sets of vertical plates 521 are jointly rotatably installed with a rotating column 522. The rotating column 522 is fixedly installed with a transmission gear plate 523 at one end facing the filter disc 4. The annular side wall of the filter disc 4 is fixedly installed with a first gear ring 524. The first gear ring 524 is meshed with the transmission gear plate 523. The rotating column 522 is away from the transmission gear plate 523. 3 is fixedly mounted with a guide plate 525 at one end, and an arc-shaped guide rack 526 is provided on the surface of the guide plate 525. A piston plate 527 is slidably mounted in the water storage cylinder 511. A positioning rack 528 is fixedly mounted on the end of the piston plate 527 facing the outside of the water storage cylinder 511. The positioning rack 528 is engaged with the guide rack 526. A return spring 529 is fixedly mounted in the water storage cylinder 511, and the telescopic end of the return spring 529 is connected to the piston plate 527.

[0040] The return spring 529 pushes the piston plate 527 to the opening of the water storage cylinder 511, and the aqueous solution passes through the water inlet 512 and is filled into the water storage cylinder 511. When the filter plate 4 rotates, it drives the first ring gear 524 to rotate synchronously. The first ring gear 524 engages with the transmission gear plate 523 for transmission, which can drive the rotating column 522 to rotate on the surface of the two sets of vertical plates 521. The rotating column 522 drives the guide plate 525 to rotate synchronously. The guide plate 525 drives the guide rack 526 to rotate synchronously. When the guide rack 526 contacts the positioning rack 528, the guide rack 526 engages with the positioning rack 528 for transmission, which can push the positioning rack 528 to move toward the water storage cylinder 511. The positioning rack 528 pushes the piston plate 527 to move synchronously toward the water storage cylinder 511. After the piston plate 527 moves to the other side of the water inlet 512, the piston plate 527 can automatically push the aqueous solution in the water storage cylinder 511 into the water conduit 513 under high pressure. The guide rack 526 rotates continuously. When the guide rack 526 and the positioning rack 528 separate from each other, the return spring 529 pushes the piston plate 527 to move back to its original position. The aqueous solution in the box 1 again flows through the water inlet 512 and fills the water storage cylinder 511. This cycle is repeated, and the nozzle 514 can be controlled to intermittently perform high-pressure cleaning on the mesh 41.

[0042] The air guide tube 6 supports and positions the sleeve 721, and the supporting rod 722 supports and positions the multiple groups of stirring rods 71 on the outside of the sleeve 721. The air storage disk 2 drives the air guide tube 6 to rotate in the inner cavity of the box 1. The air guide tube 6 drives the sleeve 721 and the stirring rod 71 to rotate synchronously. The second gear ring 723 on the surface of the sleeve 721 rolls along the surface of the third gear ring 725. The second gear ring 723 controls the sleeve 721 to rotate on the surface of the air guide tube 6. The sleeve 721 drives the multiple groups of stirring rods 71 to rotate around the air guide tube 6. The stirring rods 71 can efficiently crush the bubbles discharged from the bottom end of the air guide tube 6 in the aqueous solution.

[0043] like Figure 4 、 Figure 7 As shown, as a preferred embodiment of the present invention, the longitudinal rotation assembly 73 includes a positioning gear disc 731 fixedly installed at one end of the supporting rod 722 away from the sleeve 721, and multiple groups of second brackets 732 are fixedly installed on the surface of the air guide tube 6. The multiple groups of second brackets 732 are jointly fixedly installed with a fourth gear ring 733, and the positioning gear disc 731 is meshed and connected with the fourth gear ring 733.

[0044] Multiple groups of second brackets 732 support and position the fourth gear ring 733 on the outside of the air duct 6. The sleeve 721 drives the load-bearing rod 722 to rotate around the air duct 6. The positioning gear disc 731 at the end of the air duct 6 rolls along the surface of the fourth gear ring 733. The positioning gear disc 731 controls the load-bearing rod 722 to rotate around its own axis on the surface of the sleeve 721. The load-bearing rod 722 drives the stirring rod 71 to rotate synchronously in the vertical plane, which can further improve the stirring effect of the stirring rod 71 in the aqueous solution and can efficiently refine the bubbles.

[0045] like Figure 2 、 Figure 6 As shown, as a preferred embodiment of the present invention, multiple sets of third brackets 8 are fixedly installed on the inner wall of the box body 1, and a positioning block 9 is fixedly installed on one end of the third bracket 8 facing the gas storage disk 2, and the gas storage disk 2 is rotatably installed between the multiple sets of positioning blocks 9.

A limiting plate 15 is fixedly installed on one end of the guide rod 10 located on the outside of the piston plate 527.

[0048] The multiple sets of guide rods 10 position the piston plate 527 in the inner cavity of the water storage cylinder 511 . When the piston plate 527 moves in the water storage cylinder 511 , the multiple sets of guide rods 10 can effectively improve the stability of the piston plate 527 .

[0049] like Figure 4 As shown in FIG. 1 , as a preferred embodiment of the present invention, a transverse plate 16 is fixedly installed in the inner cavity of the box body 1 , and the transverse plate 16 is rotatably connected to the transverse column 3 .

[0050] When the cross column 3 rotates in the inner cavity of the box body 1, the cross plate 16 can effectively improve the stability of the cross column 3 during rotation.

[0051] like Figure 2 、 Figure 3 、 Figure 7 As shown in FIG. 1 , as a preferred embodiment of the present invention, a plurality of air guide branches 18 are provided at the bottom of the air guide tube 6. The air guide branches 18 can control the air discharged from the air guide tube 6 to form multiple bubbles that move upward in the aqueous solution, and the stirring rod 71 can efficiently stir and refine the bubbles.

[0052] The working principle of the present invention is as follows: an appropriate amount of aqueous solution is injected into the inner cavity of the housing 1 through the water inlet pipe 13, and an external air extraction device transports air into the air inlet pipe 11. When the air flows in the air inlet pipe 11, it passes through the mesh 41 on the surface of the filter disc 4, and impurities will adhere to the surface of the mesh 41. The mesh 41 can effectively filter impurities contained in the air. The air after preliminary filtration flows from the air inlet pipe 11 into the air storage chamber 21. The air in the air storage chamber 21 further flows into the air guide pipe 6. The bottom end of the air guide pipe 6 is inserted into the water. The air is discharged from the bottom end of the air guide pipe 6. The air forms a bubble structure in the aqueous solution and moves upward. The aqueous solution can effectively dissolve and adsorb impurities in the air. The filtered air is discharged from the air outlet pipe 12.

[0053] When filtering the air, the motor 31 drives the horizontal column 3 to rotate and then drives the filter disc 4 to rotate synchronously in the inner cavity of the box body 1. The bottom of the filter disc 4 is immersed in the aqueous solution, and the aqueous solution can wet the mesh 41 on the surface of the filter disc 4. When the filter disc 4 rotates, it can control the meshes 41 in different areas to move to the fracture 111 in turn to filter and remove impurities from the air, which can effectively improve the filtering and removing impurities effect of the mesh 41 on the air. The mesh 41 area with attached impurities rotates to the outside of the fracture 111 and continues to rotate and immerse in the aqueous solution. The aqueous solution can perform a preliminary cleaning treatment on the impurities attached to the mesh 41. The filter disc 4 continues to rotate, and the aqueous solution passes through the water inlet 512 and is filled into the water storage cylinder 511. When the filter disc 4 rotates, it drives the first gear ring 524 to rotate synchronously. The first gear ring 524 is engaged with the transmission gear disc 523 for transmission, which can drive the rotating column 522 to rotate on the surface of the two sets of vertical plates 521. The rotating column 522 drives the guide disc 525 The guide plate 525 rotates synchronously, driving the guide rack 526 to rotate synchronously. When the guide rack 526 contacts the positioning rack 528, the guide rack 526 and the positioning rack 528 mesh and drive, pushing the positioning rack 528 into the water storage cylinder 511. The positioning rack 528 pushes the piston plate 527 to move synchronously into the water storage cylinder 511. After the piston plate 527 moves to the other side of the water inlet 512, the piston plate 527 can automatically push the aqueous solution in the water storage cylinder 511 into the water conduit 513 under high pressure. The aqueous solution in the water conduit 513 is sprayed by the nozzle 514, which controls the high-pressure water to spray toward the surface of the mesh 41. The high-pressure water can effectively clean impurities attached to the surface of the mesh 41, and the cleaned impurities are deposited at the bottom of the aqueous solution. High-pressure flushing of the mesh 41 on the surface of the filter disc 4 can further improve the cleaning effect of the mesh 41. After cleaning, the moistened mesh 41 is rotated into the fracture 111 again, which can maintain a continuous and efficient filtering and impurity removal effect on the air flowing in the intake pipe 11.

[0054] When the horizontal column 3 rotates, it drives the fixed gear disc 192 to rotate synchronously. The fixed gear disc 192 engages with the bottom gear ring 191 to drive the air storage disc 2 to rotate around its own axis within the inner cavity of the housing 1. The air storage disc 2 drives the air duct 6 to rotate synchronously. The bottom end of the air duct 6 rotates in the aqueous solution, thereby controlling the discharge of bubbles from different directions within the aqueous solution. When the air duct 6 rotates, it drives the stirring rod 71 to rotate synchronously. The air duct 6 drives the sleeve 721 and the stirring rod 71 to rotate synchronously. The second gear ring 723 on the surface of the sleeve 721 rolls along the surface of the third gear ring 725. The second gear ring 723 controls the rotation of the sleeve 721 on the surface of the air duct 6. The sleeve 721 drives multiple groups of stirring rods 71 to rotate around the air duct 6. The stirring rods 71 can effectively crush the bubbles discharged from the bottom end of the air duct 6 in the aqueous solution. The sleeve 721 drives the supporting rod 722 to rotate around the air guide tube 6, and the positioning gear disc 731 at the end of the air guide tube 6 rolls along the surface of the fourth gear ring 733. The positioning gear disc 731 controls the supporting rod 722 to rotate around its own axis on the surface of the sleeve 721. The supporting rod 722 drives the stirring rod 71 to rotate synchronously in the vertical plane, which can further improve the stirring effect of the stirring rod 71 in the aqueous solution. When the bubbles move upward, the stirring rod 71 can efficiently crush larger bubbles. The larger bubbles split in the aqueous solution to form batches of small bubbles. The air in the bubbles can fully contact with the clean water, which can effectively improve the dissolution and adsorption effect of the clean water on impurities in the air in the bubbles.
