Description

Technical Field

[0001] The invention relates to the technical field of waste resin recovery, and in particular to a waste gas adsorption waste resin recovery device. Background Art

[0002] Waste gas adsorption resin is a high molecular polymer with a porous structure. There are a large number of tiny pores inside it. These pores provide a huge specific surface area, allowing the resin to effectively adsorb pollutants in the waste gas. In the chemical, pharmaceutical, printing, coating and other industries, waste gas adsorption resin is widely used to remove organic solvents, volatile organic compounds (VOCs) and other harmful substances in waste gas.

[0003] After use, the waste gas adsorption resin needs to be recycled, that is, the waste gas adsorption resin needs to be recycled and reused; currently, there are some resin waste recovery devices on the market, but most of these devices have some shortcomings. For example, in the crushing process, many devices have poor crushing effects, and it is difficult to crush large pieces of resin waste into small particles that meet the needs of subsequent processing. It is often necessary to set up multiple crushing rollers for multi-stage crushing, which not only increases the complexity and cost of the equipment, but also reduces production efficiency. Moreover, during the crushing process, a large amount of friction will be generated between the crushing cutter head and the resin waste, causing the crushing cutter head to heat up. The existing devices lack effective heat dissipation measures, which makes the crushing cutter head easily damaged due to overheating, shortening the service life of the equipment, and also affecting the normal progress of the crushing work.

[0004] In addition, in terms of the screening of resin waste, the screening efficiency of some devices is low, and the screen drum is easily blocked by some resin waste, which affects the screening effect of the resin waste and causes uneven quality of the recycled resin. Moreover, in the crushing and screening process of the existing device, the linkage between the various components is poor, and multiple power sources are required to drive different components to work, which increases energy consumption and equipment maintenance costs.

[0005] To this end, the present application proposes a waste gas adsorption resin waste recovery device. Summary of the invention

[0006] The purpose of the present invention is to solve the above technical problems and to propose a waste gas adsorption resin waste recovery device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] Preferably, it further includes a driving mechanism for driving the two rotating cylinders to rotate relatively. The driving mechanism includes a motor installed on the recycling cylinder, the output end of the motor is fixedly connected to one of the rotating tubes, connecting tubes are fixed on both of the rotating tubes, first gears are fixed on both of the connecting tubes, and the two first gears are meshed with each other.

[0010] Preferably, a feeding port is penetrated through the recycling cylinder, and the feeding port is oppositely arranged to the inside of the screening cylinder.

[0011] Preferably, it further includes a transmission mechanism for driving the screening cylinder to rotate. The transmission mechanism includes a mounting block fixed on the recycling cylinder, a transmission rod rotatably arranged is penetrated through the mounting block, a through groove is penetrated through the recycling cylinder, a second gear fixedly connected to the transmission rod is arranged in the through groove, a tooth ring is fixedly connected to the outside of the screening cylinder, the second gear is meshed with the tooth ring, first transmission wheels are fixed on one of the connecting tubes and the transmission rod respectively, and the two first transmission wheels are connected by a first belt.

[0012] Preferably, it further includes a moving mechanism for driving the driving block and the crushing cutter head to move. The moving mechanism includes a fixed frame fixed inside the rotating cylinder, the fixed frame is connected to the rotating tube through a liquid delivery pipe, a piston plate is slidably connected inside the fixed frame, a plurality of springs are fixed between the piston plate and the fixed frame, the driving block is fixed on the piston plate, and a liquid supply mechanism for delivering heat exchange oil into the fixed frame is installed on one side of the bracket.

[0013] Preferably, the liquid supply mechanism includes a piston cylinder installed on a bracket. A moving piston is slidably connected inside the piston cylinder. Rotary joints are installed on both of the connecting pipes. A U-shaped pipe is installed on the two rotary joints. The U-shaped pipe is connected to the piston cylinder through a first pipeline. A first solenoid valve is installed on the first pipeline. A liquid storage tank is provided on one side of the bracket. The liquid storage tank is connected to the piston cylinder through a second pipeline. A second solenoid valve is installed on the second pipeline.

[0014] Preferably, it further includes a power mechanism for driving the moving piston to reciprocate inside the piston cylinder. The power mechanism includes a short shaft rotatably installed on the bracket. A second transmission wheel is fixed on the short shaft. A third transmission wheel is installed on the connecting pipe. The second transmission wheel and the third transmission wheel are connected by a second belt. The outer diameter of the second transmission wheel is larger than that of the third transmission wheel. A circular plate is fixed on the short shaft. A connecting rod is eccentrically hinged to the circular plate. The connecting rod is hinged to the moving piston.

[0015] Preferably, a discharge slot is provided through the bottom of the recovery cylinder. The discharge slot is arranged in a long strip shape.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The relative rotation of the two rotating cylinders drives the crushing cutter heads to circularly crush the resin waste, and the distance between the crushing cutter heads on the two rotating cylinders can be automatically adjusted, enabling large pieces of resin waste to be gradually crushed into smaller particles without multi-stage crushing, reducing the equipment complexity and cost.

[0018] 2.

[0019] 3. The screening cylinder continuously rotates to screen the crushed resin waste. Some of the crushed resin waste can fall through the screening holes of the screening cylinder and be discharged from the discharge slot at the bottom of the recovery cylinder. During the crushing process, the resin waste splashes and impacts the screening cylinder, causing it to vibrate. This vibration can clean the screening cylinder, prevent some resin waste from blocking the screening holes of the screening cylinder, improve the screening effect, and ensure the quality of the recycled resin.

[0020] 4. The entire device is driven by one motor, and the linkage of multiple components is realized by using transmission mechanisms such as gears and belts, reducing the use of power sources, lowering energy consumption and equipment maintenance costs, and improving the overall operation efficiency and reliability of the device.

[0021] 5. During the crushing process, when there is a large amount of resin waste between the crushing cutter heads, the crushing cutter heads will move inward towards the inside of the rotating cylinder due to the reaction force, squeezing a small amount of heat exchange oil in the corresponding fixed frame into other fixed frames, which plays a role in relieving the force on the crushing cutter heads, avoiding the increase in friction of the crushing cutter heads caused by a large amount of resin waste, and achieving the protection of equipment such as motors.

[0022] 6. A deflector is fixed inside the sieve cylinder. When the sieve cylinder rotates, the deflector rotates accordingly. When the deflector drives the resin waste to move to the upper part, the resin waste separates from the deflector due to gravity, and can convey the resin waste in the sieve cylinder between two relatively rotating rotating cylinders, and can circularly crush the resin waste until it passes through the sieve cylinder.

[0023] In summary, the present invention only requires one power source, reduces energy consumption and maintenance costs, can efficiently crush resin waste, does not require multi-stage crushing, can dissipate heat from the crushing cutter heads during use, extends the service life, effectively avoids the blockage of the sieve cylinder, ensures the screening efficiency of the crushed resin, can adjust the distance between the crushing cutter heads, control the particle size of the resin particles, and ensure the stable quality of the recycled resin.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Referring to Figures 1-6 , an exhaust gas adsorption resin waste recycling device includes a bracket 1. A recovery cylinder 2 is installed on the bracket 1. Two rotating pipes 29 are rotatably connected inside the recovery cylinder 2. A rotating cylinder 30 which is coaxially arranged is fixedly connected to the outside of the rotating pipe 29. It further includes a driving mechanism for driving the two rotating cylinders 30 to rotate relatively. The driving mechanism includes a motor 3 installed on the recovery cylinder 2. The output end of the motor 3 is fixedly connected to one of the rotating pipes 29. Connecting pipes 16 are fixed on both of the two rotating pipes 29. First gears 15 are fixed on both of the two connecting pipes 16. The two first gears 15 are meshed with each other. When the motor 3 works, it drives the rotating pipe 29 to rotate. The rotation of the rotating pipe 29 drives the connecting pipe 16 and the first gear 15. The first gear 15 drives the other first gear 15 to rotate relatively, thereby realizing the relative rotation of the two rotating cylinders 30.

[0033] A plurality of chutes 37 penetrate through the rotating cylinder 30. A plurality of driving blocks 31 are slidably connected in the chutes 37. Crushing cutter heads 32 for crushing the resin are fixed on the driving blocks 31. The crushing cutter heads 32 are fixed on the driving blocks 31 by bolts so as to replace the severely worn crushing cutter heads 32 subsequently.

[0034] The inner wall of the recovery cylinder 2 is rotatably connected with a sieve cylinder 38 located outside the two rotating cylinders 30. Among them, a feeding port 4 penetrates through the recovery cylinder 2. The feeding port 4 is arranged opposite to the inside of the sieve cylinder 38. A feeding pipe can also be installed inside the feeding port 4 or connected to an external screw conveyor so as to add the resin waste to be crushed into the recovery cylinder 2.

[0035] It also includes a transmission mechanism for driving the rotation of the screening cylinder 38. The transmission mechanism includes a mounting block 14 fixed on the recycling cylinder 2. A transmission rod 13 is rotatably arranged through the mounting block 14. A through groove 10 is provided through the recycling cylinder 2. A second gear 9 fixedly connected to the transmission rod 13 is arranged in the through groove 10. A toothed ring 27 is fixedly connected to the outside of the screening cylinder 38. The second gear 9 meshes with the toothed ring 27. A first transmission wheel 12 is fixed on each of one connecting pipe 16 and the transmission rod 13. The two first transmission wheels 12 are connected by a first belt 11. When the connecting pipe 16 rotates, the first transmission wheel 12 rotates. Under the transmission of the first belt 11, the transmission rod 13 rotates. The rotation of the transmission rod 13 drives the rotation of the second gear 9. The rotation of the second gear 9 drives the rotation of the toothed ring 27. The rotation of the toothed ring 27 drives the rotation of the screening cylinder 38.

[0036] The rotation of the screening cylinder 38 can screen the crushed resin waste. Part of the crushed resin waste falls through the screening cylinder 38. Since a discharge groove is provided through the bottom of the recycling cylinder 2 and the discharge groove is arranged in a long strip shape, the resin waste passing through the screening cylinder 38 can be discharged through the discharge groove.

[0037] During the crushing process, since the resin waste is squeezed and crushed, it is bound to cause the resin waste to splash and hit the screening cylinder 38. This will cause the screening cylinder 38 to vibrate, so that the screening cylinder 38 can be cleaned to prevent it from being blocked by some resin waste and affecting the screening of the resin waste.

[0038] A flow guide plate 28 is fixed inside the screening cylinder 38. When the screening cylinder 38 drives the flow guide plate 28 to rotate, the resin in the screening cylinder 38 can be conveyed between the two rotating cylinders 30. The relative rotation of the two rotating cylinders 30 drives the rotation of the crushing cutter heads 32. The rotating crushing cutter heads 32 can crush the resin cyclically.

[0039] The two crushing cutter heads 32 will be driven to extend outward from the rotating cylinders 30, and the gap between the crushing cutter heads 32 on the two rotating cylinders 30 decreases, so that the particle size of the crushed resin is reduced. Further explanation: It also includes a moving mechanism for driving the driving block 31 and the crushing cutter heads 32 to move. The moving mechanism includes a fixed frame 34 fixed inside the rotating cylinder 30. The fixed frame 34 is connected to the rotating pipe 29 through a liquid delivery pipe 33. A piston plate 35 is slidably connected inside the fixed frame 34. The piston plate 35 is made of metal and is wrapped by a sealing ring on its outside to increase the sealing performance with the fixed frame 34.

[0040] A plurality of springs 36 are fixed on the piston plate 35 and the fixed frame 34. The driving block 31 is fixed on the piston plate 35. The heat exchange oil is transported into the fixed frame 34 through the rotating pipe 29 and the liquid delivery pipe 33. The amount of oil in the fixed frame 34 increases, so as to drive the piston plate 35 to move, and further drive the driving block 31 and the crushing cutter head 32 to move, and the distance between the two crushing cutter heads 32 can be reduced. On the contrary, when the amount of oil in the fixed frame 34 decreases, the driving block 31 and the crushing cutter head 32 can be driven to move, and the distance between the two crushing cutter heads 32 can be increased to crush larger resin waste.

[0041] As described above, the distance between the two crushing cutter heads 32 can be gradually reduced, so that the large resin waste can be gradually crushed, the particles of the crushed material can be gradually reduced, and the crushing requirements can be met.

[0042] Friction will be generated during the crushing process, which will cause the crushing cutter head 32 to heat up. Through the transmission of the driving block 31 and the piston plate 35, the heat can be transferred to the heat exchange oil, so as to realize the heat dissipation of the crushing cutter head 32. It only needs to replace the heat exchange oil in the fixed frame 34. The specific method is as follows:

[0043] A liquid supply mechanism for transporting heat exchange oil into the fixed frame 34 is installed on one side of the bracket 1. The liquid supply mechanism includes a piston cylinder 5 installed on the bracket 1. A moving piston 26 is slidably connected in the piston cylinder 5. Rotary joints 17 are installed on both connecting pipes 16. A U-shaped pipe 18 is installed on the two rotary joints 17. The U-shaped pipe 18 is connected to the piston cylinder 5 through a first pipe 7. A first solenoid valve 23 is installed on the first pipe 7. A liquid storage tank 6 is provided on one side of the bracket 1. The liquid storage tank 6 is connected to the piston cylinder 5 through a second pipe 8. A second solenoid valve 24 is installed on the second pipe 8.

[0044] Further explanation: when the moving piston 26 moves away from the circular plate 21, the heat exchange oil in the piston cylinder 5 can be slowly squeezed into the first pipe 7. At this time, the first solenoid valve 23 is opened and the second solenoid valve 24 is closed; when the moving piston 26 moves to the maximum position in the piston cylinder 5 and resets, the first solenoid valve 23 is opened and the second solenoid valve 24 is closed, so that the heat exchange oil (heated by heat exchange) in the fixed frame 34 can be sucked out. When the moving piston 26 moves away from the circular plate 21 again, the first solenoid valve 23 is closed and the second solenoid valve 24 is opened, and the heat exchange oil after heat exchange in the piston cylinder 5 can be transported to the liquid storage tank 6 through the second pipe 8. When the moving piston 26 moves to the maximum position in the piston cylinder 5 and resets, the first solenoid valve 23 is closed and the second solenoid valve 24 is opened, so that the heat exchange oil in the liquid storage tank 6 can be sucked into the piston cylinder 5.

[0045] Repeat the above. When the piston 26 is moved away from the circular plate 21, the heat exchange oil in the piston cylinder 5 can be slowly squeezed into the first pipeline 7. At this time, the first solenoid valve 23 is opened and the second solenoid valve 24 is closed, etc. The working process can replace the heat exchange oil in the fixed frame 34, realizing the crushing of resin waste and also exchanging heat for the crushing cutter head 32.

[0046] It also includes a power mechanism for driving the moving piston 26 to reciprocate in the piston cylinder 5. The power mechanism includes a short shaft 25 rotatably installed on the bracket 1. A second transmission wheel 19 is fixed on the short shaft 25. A third transmission wheel 39 is installed on the connecting pipe 16. The second transmission wheel 19 and the third transmission wheel 39 are connected by a second belt 20. The outer diameter of the second transmission wheel 19 is larger than the outer diameter of the third transmission wheel 39. A connecting rod 22 is eccentrically hinged to the circular plate 21, and the connecting rod 22 is hinged to the moving piston 26. In this way, the rotation speed of the circular plate 21 can be reduced.

[0047] The present invention:

[0048] Before starting the crushing work, ensure that all components of the device are installed in place and operate normally. Add the resin waste to be crushed into the device through the feeding port 4 on the recovery cylinder 2. A feeding pipe can be installed inside the feeding port 4 or connected to an external screw conveyor to facilitate the stable and continuous transportation of the resin waste into the screening cylinder 38 in the recovery cylinder 2.

[0049] Start the motor 3 installed on the recovery cylinder 2. The output end of the motor 3 drives one of the rotating pipes 29 to rotate. Since both rotating pipes 29 are fixed with connecting pipes 16, and both connecting pipes 16 are fixed with meshing first gears 15, when the motor 3 drives one rotating pipe 29 to rotate, through the meshing transmission of the first gears 15, the two rotating pipes 29 drive the rotating cylinders 30 fixedly connected to their outsides to rotate relative to each other.

[0050] During the rotation of the rotating pipe 29, since both a connecting pipe 16 and the transmission rod 13 are fixed with first transmission wheels 12, and the two first transmission wheels 12 are connected by a first belt 11, the rotation of the connecting pipe 16 will drive the first transmission wheel 12 to rotate, and then through the transmission of the first belt 11, the transmission rod 13 will rotate. The second gear 9 fixed on the transmission rod 13 rotates accordingly, and a toothed ring 27 meshing with the second gear 9 is fixedly connected to the outside of the screening cylinder 38. Therefore, the rotation of the second gear 9 drives the toothed ring 27 to rotate, and finally the screening cylinder 38 rotates.

[0051] A deflector plate 28 is fixed inside the screening cylinder 38. When the screening cylinder 38 rotates, the deflector plate 28 rotates accordingly. When the deflector plate 28 drives the resin waste to move upward, the resin waste breaks away from the deflector plate 28 due to gravity, and the resin waste in the screening cylinder 38 can be transported between the two relatively rotating rotating cylinders 30.

[0052] When the two rotating cylinders 30 rotate relative to each other, the crushing cutter heads 32 thereon are driven to rotate. The rotating crushing cutter heads 32 circularly crush the resin waste entering between the two rotating cylinders 30.

[0053] During the crushing process, the distance between the crushing cutter heads 32 on the two rotating cylinders 30 can be automatically adjusted to control the particle size of the crushed resin particles, as follows:

[0054] Heat exchange oil is conveyed into the fixed frame 34 through the liquid supply mechanism. When the liquid supply mechanism works, the short shaft 25 in the power mechanism rotates under the transmission of the third transmission wheel 39, the second belt 20 and the second transmission wheel 19 (the outer diameter of the second transmission wheel 19 is larger than that of the third transmission wheel 39, which can reduce the rotation speed). The short shaft 25 drives the circular plate 21 to rotate, and the circular plate 21 drives the moving piston 26 to reciprocate in the piston cylinder 5 through the eccentrically hinged connecting rod 22. When the moving piston 26 moves, the heat exchange oil in the piston cylinder 5 is conveyed into the rotating pipe 29 through the first pipeline 7 (the first solenoid valve 23 is opened and the second solenoid valve 24 is closed), and then enters the fixed frame 34 through the liquid delivery pipe 33. The oil quantity in the fixed frame 34 increases, driving the piston plate 35 to move against the elastic force of the spring 36, thereby driving the driving block 31 and the crushing cutter head 32 to slowly extend outward from the rotating cylinder 30, reducing the distance between the two side crushing cutter heads 32, so that the particle size of the crushed resin is reduced, and thus the large resin waste is gradually crushed into smaller particles without multi-stage crushing.

[0055] During the crushing process, when the resin waste is squeezed, due to the reaction force, the crushing cutter head 32 will be squeezed in the reverse direction. In this way, the driving block 31, the crushing cutter head 32 and the piston plate 35 can be driven to move, and a small amount of heat exchange oil in the corresponding fixed frame 34 can be squeezed into other fixed frames 34. Thus, when there is more resin waste between the crushing cutter heads 32, it will play a role in relieving the force on the crushing cutter heads 32, avoiding an increase in the friction of the crushing cutter heads 32 due to more resin waste, and also protecting the motor 3.

[0056] During the dehumidification stage, when initially crushing the larger resin waste, the liquid supply mechanism can be controlled to reduce the oil quantity in the fixed frame 34. Under the elastic force of the spring 36, the piston plate 35 drives the driving block 31 and the crushing cutter head 32 to move into the rotating cylinder 30, increasing the distance between the two side crushing cutter heads 32.

[0057] The screening cylinder 38 continuously rotates to screen the crushed resin waste. Some of the crushed resin waste falls through the screening holes of the screening cylinder 38. Since the bottom of the recovery cylinder 2 is provided with a long strip-shaped discharge groove, these resin wastes passing through the screening cylinder 38 can be discharged from the device through the discharge groove.

[0058] During the crushing process, when the resin waste is squeezed and crushed, splashing will occur. The splashing resin waste impacts on the screen cylinder 38, causing the screen cylinder 38 to vibrate. This vibration can clean the screen cylinder 38, preventing some resin waste from clogging the screen holes of the screen cylinder 38 and affecting the screening effect.

[0059] During the crushing process, friction occurs between the crushing cutter head 32 and the resin waste, causing the crushing cutter head 32 to heat up. The heat is transferred to the heat exchange oil in the fixed frame 34 through the driving block 31 and the piston plate 35, realizing the heat dissipation of the crushing cutter head 32.

[0060] When the moving piston 26 reciprocates in the piston cylinder 5, the heat exchange oil in the fixed frame 34 is replaced. The specific process is as follows: when the moving piston 26 moves away from the circular plate 21, the first solenoid valve 23 opens and the second solenoid valve 24 closes, slowly squeezing the heat exchange oil in the piston cylinder 5 into the first pipeline 7 and then transporting it into the fixed frame 34; when the moving piston 26 moves to the maximum position in the piston cylinder 5 and resets, the first solenoid valve 23 opens and the second solenoid valve 24 closes, sucking out the heat exchange oil with increased temperature in the fixed frame 34; when the moving piston 26 moves away from the circular plate 21 again, the first solenoid valve 23 closes and the second solenoid valve 24 opens, transporting the heat exchange oil after heat exchange in the piston cylinder 5 to the liquid storage tank 6 through the second pipeline 8; when the moving piston 26 moves to the maximum position in the piston cylinder 5 and resets, the first solenoid valve 23 closes and the second solenoid valve 24 opens, sucking the heat exchange oil in the liquid storage tank 6 into the piston cylinder 5. In this way, the heat exchange oil in the fixed frame 34 is replaced in a cycle, ensuring the heat dissipation effect of the crushing cutter head 32.

[0061] This process also controls the slow relative or opposite movement of the crushing cutter head 32. Therefore, large pieces of resin waste can be gradually crushed into small particle resin waste without setting multiple crushing rollers for multi-stage crushing, and the protection of the crushing cutter head 32 is also achieved.

[0062] 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 inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
