Description

Technical Field

[0001] The invention relates to the technical field of tire exhaust gas filtering and dust removal, and in particular to an exhaust gas filtering and adsorption device for polishing tires. Background Art

[0002] Tires are light-colored due to their use of natural rubber (milky white). Carbon black was later added to darken them for enhanced wear resistance. However, some high-end models still retain some white sidewall lettering, shifting from anti-aging properties (white rubber) to decorative features to enhance the overall aesthetics of the tire. This white rubber is polished away through a later polishing process, where the thin layer of black rubber on the tire sidewall surface is removed, revealing the white decorative graphics or lettering. However, the polishing process generates black, toxic gases. These gases have a certain temperature and contain sulfides. If directly extracted by an exhaust fan, they will severely shorten the exhaust fan's service life and even cause safety accidents. For example, the invention patent with patent publication number CN114083435B still has many shortcomings in actual use: first, the exhaust gas diffusion direction is not fixed, and the coverage area of ​​the hood is limited. During the grinding process, there will still be exhaust gas that cannot be inhaled; second, the exhaust gas is filtered through the filter, which can only remove the particulate dust generated during the grinding process. This part of the dust will soon accumulate, and the filter needs to be replaced frequently, which seriously reduces work efficiency; third, the exhaust gas enters the cooling tank and, after atomization and spraying, a part of the exhaust gas will form black colloid particles and accumulate at the bottom of the cooling tank. Over time, it is very easy to clog the drainage hole, and this part of the black colloid particles is not easy to clean; fourth, after the black colloid particles clog the drainage hole, as the water level rises and exceeds the sleeve position, the load of the exhaust fan continues to increase, and the spiral blades set up isolate the exhaust gas in independent spaces. The negative pressure formed by the exhaust fan is not enough to draw the exhaust gas, and at this time, the equipment cannot work normally. Summary of the Invention

[0003] In order to make up for the shortcomings of the existing technology, the present invention provides an exhaust gas filtering and adsorption device for polishing tires. It has a reasonable structural design, is easy to operate and move, and adopts multiple stations for air induction, which can induce air in all directions for the exhaust gas to the greatest extent without leaving dead corners.

A plurality of L-shaped branch pipes 5 are horizontally spaced along the circumferential direction of the tank body 4 at the lower part of the side wall of the tank body 4. The horizontal section of the L-shaped branch pipe 5 is connected to the tank body 4, and the vertical section is perpendicular to the surface direction of the base 1. A notch 6 is provided on the side wall of the card seat 3 corresponding to the horizontal section of each L-shaped branch pipe 5; a sealing is provided at the opening at the top of the tank body 4. Cover 7, the sealing cover 7 is connected to the tank body 4 by a number of locking members evenly arranged on its edge. A ventilation cylinder 8 extending into the tank body 4 is vertically provided in the sealing cover 7. An exhaust outer pipe 9 connected to the ventilation cylinder 8 is vertically provided in the center of the surface of the sealing cover 7. An air duct of an exhaust fan 10 is connected to the exhaust outer pipe 9. An air guide pipe 11 is connected to the side wall of the upper part of the ventilation cylinder 8. The outer end of the air guide pipe 11 is sealed, and a number of air guide holes 12 are provided on the upper part of the side wall of the air guide pipe 11; an annular guide rail 13 is horizontally provided on the upper part of the side wall of the tank body 4, and a number of support mechanisms that cooperate with the corresponding L-shaped branch pipe 5 are provided at intervals on the annular guide rail 13.

[0030] Optionally, the support mechanism includes an arc-shaped card seat 14 that is movably connected to the annular guide rail 13, and a slider 16 that is movably connected to the slide groove 15 on the corresponding side of the annular guide rail 13 is provided on the upper and lower sides of the inner wall of the arc-shaped card seat 14. A sleeve 17 is horizontally provided in the middle of the outer wall of the arc-shaped card seat 14, and a telescopic rod 18 is provided in the sleeve 17. The outer end of the telescopic rod 18 is bent downward, and a spherical support 19 is provided at its end. A clamping member is movably connected to the spherical support 19 through a ball head 20 provided on the top of the clamping member. The arc-shaped holders 14 on the left and right sides of 17 are respectively provided with first locking bolts 21 that movably pass through the arc-shaped holder 14 and abut against the annular guide rail 13, the sleeve 17 is provided with a second locking bolt 22 that movably passes through the sleeve 17 and abuts against the telescopic rod 18, and the spherical support 19 is provided with a third locking bolt 23 that movably passes through the spherical support 19 and abuts against the ball head 20; an induced draft tube 24 is clamped in the clamping member, the outer end of the induced draft tube 24 is wide-mouthed, and the inner end is connected to the L-shaped branch pipe 5 through a hose.

[0031] Optionally, the clamping member includes a fixed block 25, which is connected to the ball head 20 through a connecting rod 26, a left clip 27 is fixed on one side of the fixed block 25, a groove 28 is provided in the fixed block 25, and a right clip 29 that cooperates with the left clip 27, the upper end of which is movably clamped in the groove 28 of the fixed block 25, and the left clip 27 and the right clip 29 are connected by a fourth locking bolt 30 at the bottom.

[0032] Optionally, a cooling mechanism is further included within the ventilation cylinder 8. The cooling mechanism comprises a liquid inlet pipe 31 and a liquid outlet pipe 32, each vertically disposed within the ventilation cylinder 8. The upper ends of the liquid inlet pipe 31 and the liquid outlet pipe 32 respectively pass through the sealing cover 7 and are fixedly connected thereto. The lower ends of the liquid inlet pipe 31 and the liquid outlet pipe 32 respectively pass through the bottom of the ventilation cylinder 8 and are connected via an S-shaped pipe 33. During use, a refrigeration device must first be connected to the liquid inlet pipe 31. Cold air or cold liquid enters the S-shaped pipe 33 through the liquid inlet pipe 31, and the S-shaped pipe exchanges heat with the water within the tank body 4. Thus, the cooling mechanism effectively exchanges heat with the water within the tank body 4, preventing the water temperature within the tank body from rising due to prolonged reaction with black smoke, thereby reducing the adsorption efficiency of the black smoke.

[0033] Optionally, a thermal insulation plate 34 is horizontally provided on the inner wall of the upper portion of the ventilation cylinder 8. The thermal insulation plate 34 is disposed below the air guide tube 11. Thermal insulation cotton 35 is respectively provided on the liquid inlet pipe 31 and the liquid outlet pipe 32 above the thermal insulation plate 34. The thermal insulation plate 34 allows more energy to be concentrated in the ventilation cylinder 8 below the thermal insulation plate 34, thereby maintaining a lower temperature of the ventilation cylinder 8 and enabling better heat exchange with the water in the tank 4.

[0034] Optionally, a flange 36 is provided along the circumference of the upper inner wall of the tank body 4. A filter disc 37, which is movably sleeved on the ventilator 8, is snapped onto the flange 36. Lifting handles 38 are provided on either side of the filter disc 37. The filter disc 37 intercepts colloid particles that float to the water level of the tank body 4, preventing them from falling into the air guide holes 12 of the air guide tube 11 due to the generated waves, thereby allowing the device to maintain operation for a long time.

[0035] Optionally, a drain pipe 39 is connected to the middle of the vertical sidewall of the L-shaped branch pipe 5, and a switch valve 40 is installed on the drain pipe 39. When dust accumulates in the L-shaped branch pipe 5, the switch valve 40 can be opened to drain the dust mixed with the water. Alternatively, an external water supply pipe can be connected to the drain pipe 39 to inject water into the tank body 1. The L-shaped branch pipe 5 and the tank body 4 form a communicating vessel, thereby ensuring the water level in the tank body 4 is maintained.

[0036] Optionally, the locking member includes a locking seat 41 arranged at the top of the side wall of the tank body 4, the upper part of the locking seat 1 extends beyond the top of the tank body 4, a slot 42 is provided on the surface of the locking seat 41, and a block 43 is provided at the bottom of the side wall of the sealing cover 7 and is engaged in the slot 42. The block 43 is connected to the locking seat 41 through a fifth locking bolt 44.

[0037] Optionally, the angle formed between the horizontal sections of two adjacent L-shaped branches 5 and the axis of the tank body 4 is less than 30 degrees. The L-shaped branches 5 are concentrated on one side of the tank body 4, thereby increasing the multi-angle wind coverage area.

[0038] Optionally, a push-pull handle 45 is provided on the base 1 outside the holder 3. By pushing and pulling the handle 45, the tank body 4 can be easily moved to better adjust the angle with the grinding station.

[0039] Before using this device, first fill the tank 4 with water. Stop filling when the water level exceeds the height of the drain valve 39 on the L-shaped branch pipe 5. Then, connect the liquid inlet pipe 31 and the liquid outlet pipe 32 to the cold source equipment, and adjust the angles of each induced draft tube 24 to fully cover the grinding station. Use two first locking bolts 21 to lock the corresponding arc-shaped holder 14 on the annular guide rail 13 to control the approximate position of the induced draft tube 24. Use the second locking bolt 22 to adjust the length of the telescopic rod 18 extending from the sleeve 17 and its direction within the sleeve 17, thereby determining the position of the spherical support 19. Use the third locking bolt 23 to control the angle of the ball head 20 within the spherical support 19, thereby controlling the specific angle of the induced draft tube 24 through the clamping member. Finally, connect the induced draft tube 24 to the L-shaped branch pipe with a hose.

[0040] During use, the exhaust fan 10 is started and the exhaust fan 10 draws the air in the tank body 4 outwards through the air guide holes 12 of the air guide tube 11, the ventilation cylinder 8 and the exhaust outer tube 9 in sequence. Due to the negative pressure generated in the tank body 4, the air in the upper part of each L-shaped branch pipe 5 connected to the tank body 4 is continuously drawn into the tank body 4, thereby continuously providing suction for the induced draft tube 24. The black smoke and dust generated by the grinding process are sucked into the induced draft tube 24 and enter the L-shaped branch pipe 5 through the hose. The black smoke is sucked into the tank body 4 and cooled by the water in the tank body 4, causing the black particles to condense and float on the water surface in the tank body 4. At the same time, in order to improve the utilization rate of the L-shaped branch pipe 5, a manual valve can be added to the horizontal section of the L-shaped branch pipe 5 to control the opening and closing of the L-shaped branch pipe 5. It has a reasonable structural design, is easy to operate and move, and adopts multiple stations for air induction, which can induct the exhaust gas in all directions to the greatest extent without leaving any dead corners. At the same time, it can clean up the granular powder and black colloidal dust in time, saving time and effort, ensuring the normal inhalation of exhaust gas, preventing blockage from affecting the normal use of the equipment, and increasing the service life of the exhaust fan, thus solving the problems existing in the existing technology.
