Description

Technical Field

[0001] This utility model relates to the field of rubber anti-aging agent preparation technology, and in particular to a target dryer for preparing rubber anti-aging agents. Background Technology

[0002] During long-term storage and use, rubber and its products gradually become sticky, hard, brittle, or cracked due to the effects of heat, oxygen, ozone, variable valence metal ions, mechanical stress, light, high-energy radiation, as well as the erosion of other chemical substances and mold. This phenomenon of declining physical and mechanical properties and reduced elasticity over time is called aging. To address this, certain chemical substances need to be added to rubber and its products to improve their resistance to the aforementioned destructive effects, delay or inhibit the aging process, and thus extend the storage period and service life of rubber and its products. These substances are called antioxidants.

[0003] When drying rubber anti-aging agents, existing target dryers cause the internal gas to increase continuously as the drying process continues. Workers need to depressurize the equipment. This depressurization work, which involves workers being close to such a high-temperature device, is risky. Furthermore, during long-term drying operations, workers need to repeat this depressurization process, which is tedious and increases their workload. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: When drying rubber anti-aging agents, the internal gas in the existing target dryer increases continuously as the drying process continues, requiring workers to depressurize the device. Workers are at risk when depressurizing this high-temperature device. Furthermore, during long-term drying processes, workers need to repeat this depressurization process repeatedly, which is tedious and increases their workload. Therefore, this invention proposes a target dryer for preparing rubber anti-aging agents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A target dryer for preparing rubber anti-aging agents includes a base and columns, both of which are fixedly connected to the base, and an exhaust pipe is rotatably connected to one of the columns;

[0007] The exhaust pipe is equipped with a pressure relief component, which includes an adjustment chamber, a movable ring, a plug, a first piston plate, a rack plate, a round rod, and a straight plate. The adjustment chamber is fixedly connected to the exhaust pipe. The movable ring is fixedly connected to the inner wall of the exhaust pipe. The plug is slidably connected to the movable ring. The first piston plate is slidably connected to the adjustment chamber. The round rod is rotatably connected to the adjustment chamber. A spur gear is provided on the outer surface of the round rod. The straight plate is slidably connected to the adjustment chamber. The rack plate is fixedly connected between the straight plate and the first piston plate. The rack plate is slidably connected to the adjustment chamber and meshes with the spur gear.

[0008] Preferably, the pressure relief component further includes a second piston plate and a limiting plate. The second piston plate is slidably connected to the inner wall of the regulating chamber and fixedly connected to the straight plate. The limiting plate is fixedly connected to the second piston plate, and the end of the limiting plate away from the second piston plate is slidably connected to the plug.

[0009] Preferably, a circular plate is fixedly connected inside the exhaust pipe, the circular plate has multiple air outlets, and a straight spring is fixedly connected between the circular plate and the plug.

[0010] Preferably, a sieve plate is fixedly connected inside the exhaust pipe, and multiple tiny sieve holes are opened on the outer surface of the sieve plate. A connecting rod is fixedly connected to the plug, and an impact ring is fixedly connected to the end of the connecting rod away from the plug.

[0011] Preferably, a rotating shaft is rotatably connected to another column, one end of which is equipped with a motor. A double conical cylinder is rotatably connected between the rotating shaft and the exhaust pipe, and sealing plugs are fixedly connected to both ends of the double conical cylinder.

[0012] Preferably, a collection box is fixedly connected to the outer surface of one of the columns, the collection box is fixedly connected to the exhaust pipe, and a limit ring is fixedly connected to the end of the exhaust pipe away from the collection box, the limit ring being rotatably connected to the double conical cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The high-pressure gas inside the double cone cylinder can be smoothly discharged through the cooperation of parts such as the plug, straight spring, and regulating chamber. The entire depressurization process does not require worker participation, reducing the workload of workers and avoiding workers from directly approaching the high-temperature dryer, thus reducing the risk of worker accidents.

[0015] 2. Through the combined action of the second piston plate, the limiting plate, the straight plate and other parts, the double conical cylinder can maintain a small pressure for drying, instead of venting whenever there is pressure. Maintaining a certain pressure inside the cylinder is beneficial to improving the drying effect. The internal temperature will not fluctuate due to continuous venting, thus affecting the drying of the rubber aging agent.

[0016] 3. The sieve plate can block the rubber aging agent in the exhaust pipe, preventing blockage. Through the cooperation of parts such as plugs, connecting rods, and straight springs, the impact rod acts on the sieve plate, shaking the raw materials off the sieve plate. This prevents the sieve plate from being blocked by rubber aging agent after long-term use, thus ensuring that the exhaust pipe can be used for a long time without blockage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-5 A target dryer for preparing rubber anti-aging agents includes a base 1 and two columns 2, both of which are fixedly connected to the base 1, and an exhaust pipe 6 is rotatably connected to one of the columns 2.

[0026] The exhaust pipe 6 is equipped with a pressure relief component, which includes an adjusting chamber 9, a moving ring 10, a plug 11, a first piston plate 14, a rack plate 15, a round rod 16, and a straight plate 17. The adjusting chamber 9 is fixedly connected to the exhaust pipe 6. The moving ring 10 is fixedly connected to the inner wall of the exhaust pipe 6. The plug 11 is slidably connected to the moving ring 10. The plug 11 and the moving ring 10 are sealed to prevent air leakage. The outer surface of the plug 11 has multiple exhaust holes arranged in a ring array for exhaust. The first piston... Plate 14 is slidably connected in the regulating chamber 9. The first piston plate 14 and the regulating chamber 9 are treated to prevent air leakage. Round rod 16 is rotatably connected in the regulating chamber 9. A spur gear is provided on the outer surface of the round rod 16. Straight plate 17 is slidably connected in the regulating chamber 9. Rack plate 15 is fixedly connected between straight plate 17 and the first piston plate 14. Rack plate 15 is slidably connected in the regulating chamber 9. Rack plate 15 meshes with the spur gear. The spur gear and rack plate 15 cooperate to achieve a slowing effect on straight plate 17.

[0027] The pressure relief component also includes a second piston plate 18 and a limiting plate 19. The second piston plate 18 is slidably connected to the inner wall of the regulating chamber 9. The second piston plate 18 and the regulating chamber 9 are treated to prevent air leakage. The second piston plate 18 is fixedly connected to the straight plate 17. The limiting plate 19 is fixedly connected to the second piston plate 18. The end of the limiting plate 19 away from the second piston plate 18 is slidably connected to the plug 11. A circular plate 13 is fixedly connected inside the exhaust pipe 6. The circular plate 13 has multiple air outlets. A straight spring 12 is fixedly connected between the circular plate 13 and the plug 11. A sieve plate 20 is fixedly connected inside the exhaust pipe 6. The outer surface of the sieve plate 20 has multiple tiny sieve holes. These sieve holes can block the rubber anti-aging agent, but will not affect the passage of internal gas through the sieve plate 20. A connecting rod 22 is fixedly connected to the plug 11. An impact ring 21 is fixedly connected to one end away from the plug 11. A rotating shaft 3 is rotatably connected to another column 2. One end of the rotating shaft 3 is equipped with a motor. The motor is existing technology. When energized, it can drive the rotating shaft 3 to rotate, thereby causing the double conical cylinder 4 to rotate. The double conical cylinder 4 is rotatably connected between the rotating shaft 3 and the exhaust pipe 6. The double conical cylinder 4 is equipped with a heating component, which can raise the internal temperature to achieve the purpose of drying. Sealing plugs 5 are fixedly connected to both ends of the double conical cylinder 4. A collection box 7 is fixedly connected to the outer surface of one of the columns 2. The collection box 7 is fixedly connected to the exhaust pipe 6. A limit ring 8 is fixedly connected to the end of the exhaust pipe 6 away from the collection box 7. The limit ring 8 is rotatably connected to the double conical cylinder 4. The limit ring 8 can effectively prevent air leakage when the exhaust pipe 6 and the double conical cylinder 4 rotate relative to each other.

[0028] In this invention, when the target dryer is drying the rubber anti-aging agent, the gas pressure inside the double conical cylinder 4 increases continuously with the drying time. When the gas pressure reaches a certain level, this portion of gas begins to push the first piston plate 14 in the regulating chamber 9 downward. The first piston plate 14 drives the straight plate 17 downward through the rack plate 15. The straight plate 17 moves upward, driving the second piston plate 18 to move. The second piston plate 18 moves upward, driving the limiting plate 19 to move upward. As a result, the limiting plate 19 begins to move away from the plug 11, thus separating from the outer surface of the plug 11 and abutting against the outer surface of the moving ring 10. At this time, the limiting plate 19 loses its limiting effect on the plug 11. Due to the difference in gas pressure at both ends of the plug 11, the plug 11 is subjected to the high-pressure gas of the double conical cylinder 4. The device is pushed and begins to move towards the circular plate 13. The straight spring 12 between the circular plate 13 and the plug 11 bends under force, and the plug 11 slides out a distance from the moving ring 10. The high-pressure gas in the double cone cylinder 4 enters the other end of the exhaust pipe 6 through the exhaust hole opened on the plug 11, and finally enters the collection box 7, completing the depressurization work of the double cone cylinder 4. The entire depressurization work does not require worker participation, reducing the workload of workers. The work is only carried out when the internal pressure of the double cone cylinder 4 reaches a certain value, avoiding workers from approaching the high-temperature dryer and reducing the risk of workers' work. At the same time, it can also depressurize the double cone cylinder 4 in a timely manner to prevent the internal pressure of the double cone cylinder 4 from increasing and causing an explosion. The entire depressurization work does not require stopping the dryer, which greatly increases the drying rate.

[0029] After the pressure relief is completed, the pressure inside the double conical cylinder 4 decreases, and the internal gas loses its pushing force on the plug 11. At this time, the plug 11 returns to the moving ring 10 under the action of the straight spring 12, thus blocking the exhaust pipe 6. At this time, the first piston plate 14 and the second piston plate 18 also reset under the action of the first piston plate 14 and the second piston plate 18. Under the obstruction of the rack plate 15 and the spur gear, the first piston plate 14 and the second piston plate 18 reset at a slower speed, thus ensuring that the limiting plate 19 will continue to be stuck on the outer surface of the plug 11. The function of the limiting plate 19 is to ensure that the plug 11 is pushed only when the double conical cylinder 4 reaches a certain pressure, rather than exhausting as long as there is a certain pressure. It is necessary to maintain a certain pressure inside the double conical cylinder 4. A certain internal pressure is beneficial to improving the drying effect, and the internal temperature will rise.

[0030] During pressure relief, some of the rubber aging agent inside the double conical cylinder 4 will enter the exhaust pipe 6. To prevent this material from clogging the exhaust pipe 6, a sieve plate 20 is used to block the material entering the exhaust pipe 6, thus preventing it from clogging the plug 11. At the same time, as the material accumulates on the sieve plate 20, it will clog the tiny sieve holes on the sieve plate 20, causing the exhaust pipe 6 to lose its exhaust function. To avoid this phenomenon, each time pressure relief is performed, when the plug 11 is reset, the plug 11 moves towards the sieve plate 20 under the elastic force of the straight spring 12. The plug 11 drives the connecting rod 22 to move, and the movement of the connecting rod 22 drives the impact ring 21 to move, so that the impact ring 21 impacts the sieve plate 20, shaking the material off the sieve plate 20 and returning it to the double conical cylinder 4, thus completing the cleaning function of the sieve plate 20 and preventing the material from clogging the sieve plate 20. This ensures that the exhaust pipe 6 can be used for a long time without clogging.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
