Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment, and particularly to a waste gas treatment device for an automatic spraying production line. Background Art

[0002] The waste gas in the automatic spraying production line contains VOC (volatile organic compounds). In addition, film-forming substances, pigments, fillers, etc. will form a certain amount of solid particles. During the waste gas treatment process, first, the solid particles are removed through the filter screen in the dust filter, and the purified gas is then introduced into the activated carbon adsorption tower filled with honeycomb activated carbon, where it comes into full contact with the honeycomb activated carbon. The gas is purified by the strong adsorption of the activated carbon to organic substances, and the treated gas can meet the emission standards.

[0003] During the process of filtering the solid particles in the waste gas with the filter screen, the filter screen is prone to being blocked after long-term use. Currently, generally, the gas inlet of the waste gas is first closed, and then the blocked filter screen is removed, and a new filter screen is installed. When installing the new filter screen, it is necessary to manually repeatedly confirm whether the filter screen is installed in place, and then the gas inlet of the waste gas is opened. However, such an operation is relatively cumbersome, and it is also inconvenient to replace and clean the filter screen, which will lead to poor waste gas filtration efficiency and effect. Summary of the Invention

[0038] The sealing mechanism includes a sealing frame 91, a rubber ring 911, a return spring 92, a connecting frame 93, a top block 94, and a vertical spring 95. A sealing frame 91 is slidably provided on one side of the fixed cylinder 65 close to the exhaust pipe 3. The sealing frame 91 can slide up and down along the fixed cylinder 65. A rubber ring 911 for sealing is embedded at the top of the sealing frame 91. The rubber ring 911 is in close contact with the inner top of the rotating cylinder 63. A number of return springs 92 are connected between the sealing frame 91 and the fixed cylinder 65. A connecting frame 93 is installed on the sealing frame 91.

[0039] The filtering mechanism includes a horizontal shaft 101, a filter screen 102, a swing gear 103, a torsion spring 104, an arc-shaped strip 105 and a side tooth block 106. Four horizontal shafts 101 are rotatably provided on the rotating cylinder 63 through bearings. A filter screen 102 for filtering solid particles in the exhaust gas is installed on each of the four horizontal shafts 101. The four filter screens 102 are respectively located in the four openings 631. A swing gear 103 is installed on one side of each of the four horizontal shafts 101. A torsion spring 104 is connected between each of the four swing gears 103 and the rotating cylinder 63. Two arc-shaped strips 105 are fixedly installed on the cross-shaped fixing frame 64. A number of side tooth blocks 106 are evenly spaced on the side of the two arc-shaped strips 105 close to each other. The swing gear 103 will contact and mesh with the side tooth block 106.

[0040] It further includes an arc-bottom fixing frame 11 and a lower tooth block 12. A cross-shaped fixing frame 64 is fixedly installed with an arc-bottom fixing frame 11. A number of lower tooth blocks 12 are installed at the lower part of the arc-bottom fixing frame 11. The swing gear 103 will contact and mesh with the lower tooth block 12.

[0041] Initially, the return spring 92 is in a stretched state, and the vertical spring 95 is in a compressed state. The elastic coefficient of the vertical spring 95 is greater than that of the return spring 92. When treating waste gas, the operator connects the waste gas pipe to the intake pipe 66. The waste gas enters the fixed cylinder 65 after passing through the ball valve body 73 and the intake pipe 66. The waste gas passes through the sealing frame 91 and one of the filter meshes 102 and then is discharged into the subsequent treatment equipment through the exhaust pipe 3. The solid particles in the waste gas will be intercepted by the filter mesh 102. When one of the filter meshes 102 is blocked by the solid particles in the waste gas, the operator controls the telescopic rod of the electric push rod 71 to extend. The telescopic rod of the electric push rod 71 drives the L-shaped plate 72 and the vertical rack 75 to move downward. The downward movement of the vertical rack 75 drives the column gear 74 to rotate. The column gear 74 drives the ball valve body 73 to rotate, and the ball valve body 73 will no longer communicate with the intake pipe 66. At this time, the vertical rack 75 is separated from the column gear 74. When the L-shaped plate 72 moves downward, it drives the driving rack 83, the top block 94, and the vertical spring 95 to move downward. At this time, the vertical spring 95 will stretch and reset, and the top block 94 will always contact the connecting frame 93 to prevent the sealing frame 91 and the rubber ring 911 from moving. The L-shaped plate 72 continues to drive the vertical rack 75, the driving rack 83, the top block 94, and the vertical spring 95 to move downward. After the top block 94 is separated from the connecting frame 93, under the action of the return spring 92, the sealing frame 91 and the rubber ring 911 will be separated from the inner side wall of the rotating cylinder 63. At this time, the driving rack 83 just meshes with the gear ring 82. The L-shaped plate 72 continues to drive the vertical rack 75, the driving rack 83, the top block 94, and the vertical spring 95 to move downward. The driving rack 83 drives the gear ring 82 to rotate 90 degrees and then stops. The gear ring 82 drives the rotating cylinder 63, the annular guide rail 62, the four horizontal shafts 101, the four filter meshes 102, the four oscillating gears 103, and the four torsion springs 104 to rotate 90 degrees and then stop. Two of the oscillating gears 103 will contact and then separate from each side tooth block 106 on the two arc-shaped bars 105 in turn. Under the action of two of the torsion springs 104, two of the oscillating gears 103 will continuously swing back and forth. Two of the oscillating gears 103 drive two of the horizontal shafts 101 and two of the filter meshes 102 to continuously swing back and forth. The solid particles on two of the filter meshes 102 will be shaken off. After one of the oscillating gears 103 moves and contacts the lower tooth block 12 on the arc bottom fixed frame 11, the oscillating gear 103 drives the lower horizontal shaft 101 and the lower filter mesh 102 to swing, and the torsion spring 104 twists accordingly. After the lower filter mesh 102 swings, it will no longer close the lower opening 631. The solid particles shaken off from the filter mesh 102 can be discharged through the lower opening 631. The solid particles enter the dust collection box 2 through the material guiding box 5. When the dust collection box 2 is filled with solid particles, the operator pulls out the dust collection box 2 from the box body 1, then completely empties the solid particles in the dust collection box 2, and then inserts the dust collection box 2 into the box body 1. Another cleaned filter mesh 102 can then move to between the sealing frame 91 and the upper opening 631 again;The rotating cylinder 63 is driven to rotate by the gear ring 82 and the overrunning clutch 81. Among them, the two oscillating gears 103 will come into contact with and then separate from each side tooth block 106 on the two arc-shaped bars 105 in sequence. Under the action of two torsion springs 104 among them, the two oscillating gears 103 will continuously swing back and forth. The two oscillating gears 103 drive the two horizontal shafts 101 and the two filter nets 102 to continuously swing back and forth. The solid particles on the two filter nets 102 will be shaken off. In this way, the solid particles on the two filter nets 102 can be shaken off during the process of switching the filter nets 102, so that it is not necessary to take out the filter nets 102 for cleaning, and thus it is more convenient and fast to replace and clean the filter nets 102, so as to improve the efficiency of waste gas filtration. Then the operator controls the telescopic rod of the electric push rod 71 to shorten. The telescopic rod of the electric push rod 71 drives the L-shaped plate 72 to continue to drive the vertical rack 75, the driving rack 83, the top block 94 and the vertical spring 95 to move upward. The driving rack 83 drives the gear ring 82 to rotate reversely by 90 degrees. Under the action of the overrunning clutch 81, the rotating cylinder 63 will not rotate. After the driving rack 83 is separated from the gear ring 82, the top block 94 just contacts the connecting frame 93. The top block 94 drives the connecting frame 93, the sealing frame 91 and the rubber ring 911 to move upward and reset. The reset spring 92 is stretched accordingly. After the rubber ring 911 is in close contact with the inner wall of the rotating cylinder 63, the L-shaped plate 72, the top block 94 and the vertical spring 95 continue to move upward. At this time, the vertical rack 75 meshes with the column gear 74. The top block 94 moves downward on the L-shaped plate 72, and the vertical spring 95 is compressed accordingly. The vertical rack 75 moves upward to drive the column gear 74 to rotate reversely. The column gear 74 drives the spherical valve body 73 to rotate reversely and reset. The spherical valve body 73 is communicated with the air inlet pipe 66 again. The waste gas can enter the fixed cylinder 65 again through the spherical valve body 73 and the air inlet pipe 66. The waste gas passes through the sealing frame 91 and one of the filter nets 102 and then is discharged into the subsequent treatment equipment through the exhaust pipe 3. The solid particles in the waste gas will be intercepted by the filter net 102. By reciprocating the telescopic movement of the telescopic rod of the electric push rod 71, the L-shaped plate 72, the vertical rack 75, the driving rack 83, the top block 94 and the vertical spring 95 can be driven to reciprocate. By intermittently driving the gear ring 82, the rotating cylinder 63 and the filter net 102 to rotate 90 degrees and then stop by the driving rack 83, the filter net 102 can be continuously switched, so that the blocked filter net 102 can be cleaned, and the cleaned filter net 102 can filter the solid particles in the waste gas again, so as to achieve the purpose of quickly replacing and cleaning the filter net 102, and further improve the filtration efficiency and effect of waste gas filtration. Repeating this process can continuously filter the solid particles in the waste gas.;

[0042] Embodiment 2: On the basis of Embodiment 1, as Figure 7 、 Figure 14 and Figure 15As shown, it further includes a hexagonal rod 13 and a limit groove frame 14. One hexagonal rod 13 is installed at one end of each of the four horizontal shafts 101 close to the oscillating gear 103. A limit groove frame 14 for limiting the hexagonal rod 13 is installed on the cross-shaped fixing frame 64. A limit groove is formed on the limit groove frame 14, and one of the hexagonal rods 13 is located in the limit groove on the limit groove frame 14.

[0043] It further includes a movable magnet block 15 and a fixed magnet block 16. Four movable magnet blocks 15 are evenly spaced and installed on one side of the fixed cylinder 65 close to the air inlet pipe 66. A fixed magnet block 16 is installed on one side of the rotating cylinder 63 close to the air inlet pipe 66. The sides of the fixed magnet block 16 and the movable magnet block 15 that are close to each other have opposite magnetic poles, and the fixed magnet block 16 is adsorbed to one of the movable magnet blocks 15.

[0044] After one of the horizontal shafts 101 and one of the hexagonal rods 13 move to the upper side, the upper hexagonal rod 13 will move into the limit groove on the limit groove frame 14. Under the action of the limit groove on the limit groove frame 14, the upper hexagonal rod 13 can be corrected and limited, and thus the upper horizontal shaft 101 and the upper filter net 102 can be corrected and limited to prevent the upper filter net 102 from skewing during the process of filtering solid particles in the waste gas, resulting in poor filtering effect.

[0045] The fixed cylinder 65 and the movable magnet block 15 stop after rotating 90 degrees. When one of the movable magnet blocks 15 rotates 90 degrees, it will separate from the fixed magnet block 16, and the other movable magnet block 15 will be adsorbed to the fixed magnet block 16 after rotating 90 degrees. By the mutual adsorption and cooperation of the movable magnet block 15 and the fixed magnet block 16, the fixed cylinder 65 can be fixed and corrected, so that the sealing frame 91 can be more accurately aligned with the upper filter net 102, and thus the efficiency and effect of waste gas filtration can be further improved.

[0046] The technical principle of the embodiments of the present invention has been described above in combination with specific embodiments. These descriptions are only for explaining the principle of the embodiments of the present invention and cannot be interpreted in any way as a limitation on the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the embodiments of the present invention without creative labor, and these embodiments will fall within the protection scope of the embodiments of the present invention.
