Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purification device for rubber production. Background Technique

[0002] During the rubber production process, waste gas is usually generated. For example, during the vulcanization process, rubber and other additives are heated and undergo chemical reactions, releasing vulcanization gases such as sulfur dioxide. Additionally, in some stages of rubber production, solvents may be used in processes such as rubber mixing, coating, or cleaning, and these solvents may volatilize into the air during processing, forming organic solvent waste gas.

[0003] During the rubber processing process, some solid particulate matters such as rubber dust and particles are generated. These particulate matters may form particulate waste gas through air suspension and emission. In the existing waste gas purification devices for rubber production, the particulate matters in the waste gas are first filtered during the waste gas treatment process. When the particulate matters in the waste gas are captured by the filter mesh and blocked in the mesh holes, it will cause a reduction in the effective area for waste gas flow on the filter mesh. Such blockage will affect the filtration efficiency of the device for waste gas, and at the same time, the blockage of the filter mesh makes the waste gas inside the filtration device unable to be filtered and discharged in time, increasing the pressure inside the device, which will also bring a load to the operation of the device.

[0004] Therefore, it is necessary to design a waste gas purification device for rubber production to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a waste gas purification device for rubber production is proposed.

[0015] 2. Reduction of the device load: Under the action of the brush plate, the particles and other impurities on the filter screen can be brushed off in time, so that the waste gas can smoothly pass through the mesh holes and be discharged, effectively preventing the pressure increase inside the device caused by blockage and further avoiding the increase in load.

[0016] 3. Prevention of secondary pollution: When the brush plate moves upward, due to the attraction of the magnetic plate, the brush plate does not contact the filter screen, avoiding brushing the particulate matter or dust upward, preventing the impurities from being adsorbed again and blocking the filter screen, avoiding the occurrence of secondary pollution, and ensuring the cleaning effect of the brush plate.

[0017] 4.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Referring to Figures 1-4 , an exhaust gas purification device for rubber production includes a purification tank 1. A filter cartridge 2 is provided inside the purification tank 1. An opening 3 is provided on the side wall of the filter cartridge 2. A filter mesh 4 for filtering particulate matter in the exhaust gas is provided inside the opening 3. A rotary joint 5 is provided on the filter cartridge 2. An intake pipe 6 is communicated with the rotary joint 5. The rotary joint 5 serves to connect the intake pipe 6 and the inside of the filter cartridge 2, so that the rotation of the filter cartridge 2 will not affect the connection between the two. Four brush plates 7 for cleaning the filter mesh 4 are provided inside the filter cartridge 2. A driving assembly for driving the movement of the brush plates 7 is provided inside the filter cartridge 2. A rotating assembly for controlling the rotation of the filter cartridge 2 is also provided inside the purification tank 1.

[0025] Referring to Figure 1 and Figure 4, the driving assembly includes an electric telescopic rod 14 fixedly connected to the purification tank 1. The end of the telescopic end of the electric telescopic rod 14 is pivotally connected to a pressure rod 13. The longitudinal section of the pressure rod 13 is in a T-shaped structure. A control box 9 is provided inside the filter cartridge 2. One end of the pressure rod 13 away from the electric telescopic rod 14 extends into the filter cartridge 2, and the pressure rod 13 is fixedly connected to the control box 9. The driving assembly further includes a control member. The brush plate 7 reciprocates under the action of the electric telescopic rod 14 to remove particulate matter or dust on the filter net 4, preventing the decrease in filtration efficiency caused by the blockage of the mesh holes.

[0026] Refer to Figure 2 , the control member includes a first control ring 15 and a second control ring 16 fixedly connected to the inner side of the filter cartridge 2. The first control ring 15 and the second control ring 16 are respectively located at the top and bottom of the filter cartridge 2, and inclined surfaces are provided on the lower surface of the first control ring 15 and the upper surface of the second control ring 16. Extrusion blocks 17 are fixedly connected to both the upper surface and the lower surface of the brush plate 7. The brush plate 7 is in a fan-shaped ring, and there is a certain distance between two adjacent brush plates 7. In this way, when the brush plate 7 moves towards the control box 9, it can move. Connecting rods 8 are fixedly connected to the opposite side walls of the four brush plates 7. The connecting rods 8 extend into the control box 9. The connecting rods 8 are slidably connected to the control box 9, and a second magnetic plate 11 is fixedly connected to the end of the connecting rod 8 located inside the control box 9. Four first magnetic plates 10 are fixedly connected to the four inner sides of the control box 9. Four third magnetic plates 12 respectively facing the four second magnetic plates 11 are also fixedly connected inside the control box 9. The first magnetic plates 10 and the third magnetic plates 12 are respectively located on both sides of the second magnetic plate 11. The side walls of the second magnetic plate 11 opposite to the first magnetic plates 10 have opposite magnetic polarities, and the side walls of the second magnetic plate 11 opposite to the third magnetic plates 12 also have opposite magnetic polarities. The inclined surface on the first control ring 15 can push the extrusion block 17 to move towards the control box 9. On the contrary, the inclined surface on the second control ring 16 causes the extrusion block 17 to move in the reverse direction. In this way, under the action of the first magnetic plates 10, the second magnetic plates 11 and the third magnetic plates 12, the brush plate 7 can contact the filter net 4 when moving downward and not contact the filter net 4 when moving upward, preventing the brush plate 7 from brushing the particulate matter or dust upward, and further preventing these impurities from being adsorbed and blocked in the mesh holes again when they fall.

[0027] Refer to Figure 1 and Figure 2, the rotating assembly includes a turntable 22 rotatably sleeved on the filter cartridge 2. The turntable 22 is fixedly connected to the inner side of the filter cartridge 2. Fixed plates 19 are fixed on both the turntable 22 and the side wall of the filter cartridge 2. An airbag two 20 is provided between the two fixed plates 19. An airbag one 18 is provided between the inner top surface of the pressure rod 13 and the top of the filter cartridge 2. One end of the airbag one 18 is fixed to the pressure rod 13, and the other end is rotatably connected to the filter cartridge 2. A connecting pipe 21 is communicated on the airbag one 18, and the connecting pipe 21 is communicated with the airbag two 20. Under the mutual cooperation of the airbag one 18 and the airbag two 20, the filter cartridge 2 can rotate, thereby increasing the contact area between the filter net 4 and the brush plate 7, and thus ensuring the cleaning effect of the brush plate 7.

[0028] Refer to Figure 2 , the inner bottom surface of the filter cartridge 2 is provided with an inclined surface, and the bottom of the filter cartridge 2 is provided with a discharge port. Under the action of the inclined surface, the particles brushed off can fall into the discharge port.

[0029] Refer to Figure 1 , the cross-section of the airbag one 18 is in an annular structure. The airbag one 18 is sleeved on the pressure rod 13, so that the force exerted by the airbag one 18 on the pressure rod 13 is uniform, thereby ensuring the stability of the overall structure of the device.

[0030] The specific working principle of the present utility model is as follows:

[0031] During operation, the electric telescopic rod 14 is started. The output shaft of the electric telescopic rod 14 extends and then presses down the pressure rod 13, so that the control box 9, the connecting rod 8 and the brush plate 7 move downward together. The brush plate 7 can clean the inner side of the filter net 4, so that the particles blocked in the mesh holes can be brushed off, thus preventing the blockage of the filter net 4 and ensuring the filtering efficiency of the waste gas;

[0032] During the process of the brush plate 7 moving to the extreme position at the bottom of the filter cartridge 2, the extrusion block 17 also moves along with it. When the extrusion block 17 at the bottom of the brush plate 7 contacts the first control ring 15, under the action of the inclined surface of the first control ring 15, the extrusion block 17 is extruded and moves towards the control box 9, causing the connecting rod 8, the brush plate 7, and the second magnetic plate 11 to move in the same direction. At this time, there is a certain distance between the side wall of the brush plate 7 and the filter net 4. When the brush plate 7 moves down to the extreme position, the second magnetic plate 11 contacts and attracts the third magnetic plate 12. Since there is a distance between the second magnetic plate 11 and the first magnetic plate 10 at this time, the attraction of the third magnetic plate 12 to the second magnetic plate 11 is greater than the attraction of the first magnetic plate 10 to the second magnetic plate 11. Therefore, the position of the second magnetic plate 11 will not be affected by the first magnetic plate 10. When the brush plate 7 moves up, since the second magnetic plate 11 and the third magnetic plate 12 attract each other, the brush plate 7 is always not in contact with the filter net 4. In this way, the brush plate 7 will not brush the particulate matter or dust upward, thereby preventing these impurities from being adsorbed on the filter net 4 again after falling, ensuring the effectiveness of cleaning. On the contrary, when the brush plate 7 moves up to the extreme position at the top of the filter cartridge 2, the extrusion block 17 on the upper surface of the brush plate 7 is extruded by the second control ring 16 and moves in the direction away from the control box 9, causing the brush plate 7, the connecting rod 8, and the second magnetic plate 11 to move in this direction. At this time, the brush plate 7 can contact the filter net 4, and the second magnetic plate 11 contacts and attracts the first magnetic plate 10. Similarly, at this time, the third magnetic plate 12 will not affect the position of the second magnetic plate 11. In this way, the position of the brush plate 7 can be fixed, thereby ensuring the cleaning effect of the brush plate 7 when it moves down. In this way, during the reciprocating movement of the brush plate 7, the brush plate 7 only contacts the filter net 4 when it moves down, thereby brushing the particulate matter downward for collection, ensuring the cleaning effect;

[0033] Furthermore, when the pressure rod 13 moves downward under the action of the electric telescopic rod 14, it will squeeze the first airbag 18, causing the air in the first airbag 18 to enter the second airbag 20 through the connecting pipe 21. The inflation and expansion of the second airbag 20 will squeeze the two fixing plates 19, thereby generating a thrust on the fixing plates 19 on the filter cartridge 2, causing the filter cartridge 2 to rotate. Since the brush plate 7 will not rotate, this increases the contact area between the filter net 4 and the brush plate 7, ensuring the cleaning effect and improving the filtration efficiency. On the contrary, when the pressure rod 13 moves up, a negative pressure state appears in the first airbag 18, and then the air in the second airbag 20 is sucked into the first airbag 18. The contraction of the first airbag 18 pulls the two fixing plates 19 to move towards each other, thereby causing the filter cartridge 2 to reverse and reset.

[0034] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
