Description

Technical Field

[0001] The present invention relates to the technical field of polytetrafluoroethylene particle recycling, and particularly relates to a waste recycling system for polytetrafluoroethylene materials used in new energy vehicles. Background Art

[0002] Polytetrafluoroethylene is a high-performance plastic, known for its excellent chemical resistance, heat resistance, wear resistance and low coefficient of friction. It is widely used in the field of new energy vehicles, such as battery systems, electric drive systems and body components.

[0003] After the existing polytetrafluoroethylene products are produced, there will be a lot of unused waste materials. The generated waste materials usually contain relatively high heat, and need to be cooled to room temperature before being crushed. However, relying solely on the natural cooling of the waste materials requires a long time, and the operator needs to transport the waste materials to the recycling device for recycling. Although the waste materials can drop a certain temperature during transportation, they still cannot be cooled to room temperature, resulting in a reduction in the crushing efficiency of the crushing device in the recycling device. Moreover, the waste materials will be doped with impurities and dust during transportation, and the existing recycling devices cannot effectively separate and recycle polytetrafluoroethylene and impurities such as dust. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a waste recycling system for polytetrafluoroethylene materials used in new energy vehicles to solve the problems existing in the above background art.

[0005] To achieve the above purpose, the embodiments of the present invention provide the following technical solutions:

[0006] A waste recycling system for polytetrafluoroethylene materials used in new energy vehicles includes a cooling unit and a separation unit. The separation unit includes a water tank. The cooling unit is installed at one end of the top of the water tank. The bottom of the cooling unit is provided with a bottom cover that can be automatically opened. A crushing unit is provided below the bottom cover in the upper part of the water tank. A bubble generating unit is provided at the bottom of the water tank. A vibration guiding unit is provided in the middle of the water tank. A trapping unit for collecting dust and impurities is provided at one end of the water tank far from the crushing unit.

[0007] Preferably, the cooling unit includes a cooling box. The top and bottom of the cooling box are respectively provided with openings. The bottom opening of the cooling box is installed with a bottom cover through a spring hinge. One end of the bottom cover far from the spring hinge is provided with a magnet. The water tank is made of metal. One end of the bottom cover far from the spring hinge is adsorbed to the top of the water tank through the magnet. A sealing strip is provided between the bottom cover and the bottom opening of the cooling box. A water inlet pipe is provided at the upper part of the side surface of the cooling box.

[0008] Preferably, the separation unit includes a water tank. A spray head is provided above the water tank at the top and is located above the pulverizing unit. Water is filled inside the water tank. A water pump is provided outside one end of the water tank away from the cooling unit. The water pump conveys the water inside the water tank to the water inlet pipe and the spray head respectively through a water delivery pipe.

[0009] Preferably, the pulverizing unit includes a columnar filter screen. A pulverizing shaft is provided at the axis of the filter screen. A plurality of groups of pulverizing knives are arrayed on the pulverizing shaft. A pulverizing motor for driving the pulverizing shaft is provided outside the water tank. An opening is provided at the filter screen near the bottom cover.

[0010] Preferably, the bubble generating unit includes an air chamber. The air chamber is provided at the bottom of the water tank. A plurality of air nozzles are arrayed on the upper surface of the air chamber. An air compressor communicated with the air chamber is provided outside the water tank.

[0011] Preferably, the vibration guiding unit includes a sieve plate. Limit plates are respectively provided at the middle parts of both ends inside the water tank. The horizontal heights of the two limit plates are different. The horizontal height of the limit plate below the pulverizing unit is higher than that of the other limit plate. The bottom of the sieve plate is obliquely provided on the two limit plates through a return spring. A waterproof vibrator is provided at the bottom of the limit plate. The power output end of the vibrator passes through the limit plate and works towards the sieve plate.

[0012] Preferably, the trapping unit includes a cylindrical collection bin. An installation opening is provided at the upper part of the side surface of the water tank. The collection bin is provided inside the installation opening. An opening is provided at the upper part of the collection bin. Water filtering holes are provided on the bin wall of the collection bin. A trapping motor is provided on one side of the water tank opposite to the installation opening. A rotating plate is provided inside the water tank. The trapping motor drives the rotating plate to rotate. A plurality of arc-shaped plates sleeved outside the collection bin are provided at the outer edge of the rotating plate. A handle is provided at one end of the collection bin away from the trapping motor.

[0013] Preferably, the water pump has the same horizontal height as the lowermost arc-shaped plate on the rotating plate. The water level line inside the water tank is higher than the horizontal height of the lowermost arc-shaped plate on the rotating plate and lower than the horizontal height of the bottom of the collection bin.

[0014] Preferably, the top of the air chamber is obliquely arranged. A discharge port is provided below the water tank near the water pump side. The horizontal height of the upper surface of the air chamber gradually decreases towards the discharge port.

[0015] The beneficial effects of the embodiments of the present invention are as follows:

[0016] 1. The device preliminarily cools the scraps with water. After the temperature of the scraps decreases, the bottom cover at the bottom of the cooling unit opens, and the scraps and water inside the cooling unit fall into the crushing unit inside the water tank. The water passes through the crushing unit and falls into the water tank, while the scraps remain inside the crushing unit for crushing. After being crushed to meet the requirements, the scrap particles pass through the crushing unit and enter the vibration guiding unit inside the water tank. Since the vibration guiding unit is located below the water level line, under the action of the vibration guiding unit, the scrap particles are continuously vibrated by the vibration guiding unit. At the same time, the bubble generating unit at the bottom of the water tank works, and the bubbles float from the bottom of the water tank to the water surface, facilitating cooperation with the vibration guiding unit to improve the cleaning efficiency of the scrap particles. The scrap particles will pass through the vibration guiding unit and fall to the bottom of the water tank under the vibration of the vibration guiding unit (the density of polytetrafluoroethylene is greater than that of water, so the scrap particles will sink to the bottom of the water tank). At this time, after being washed by water, the impurities and dust doped in the scrap particles float on the water surface. Through the work of the trapping unit, it is convenient to collect the impurities and dust on the water surface, facilitating the separation of the scrap particles and impurities, and realizing the recycling of polytetrafluoroethylene scraps.

[0017] 2. The crushing motor of the device starts, and the scraps are continuously crushed by the crushing knife, facilitating the crushing of the scraps into particles to pass through the filter screen. During the crushing process by the crushing knife, the water pump works. The water pump sends the water inside the water tank into the spray head through the water delivery pipe, and the spray head continuously sprays water on the scrap particles inside the filter screen for cooling, avoiding the temperature being too high when the crushing knife crushes the scrap particles, which may cause the quality of the particles to decrease.

[0018] 3. The air compressor of the device works, continuously compressing gas into the air chamber. The gas enters the bottom of the water tank through the jet nozzle to form bubbles. The bubbles will gradually increase during the rising process. When the bubbles burst, a strong impact force will be generated, and this impact force can peel off the dirt attached to the surface of the particles, thus achieving the cleaning effect.

[0019] 4. Since the sieve plate of the device is inclined, it is convenient to drive the scrap particles to move in the direction of the trapping unit during vibration, avoiding the scrap particles accumulating at the same position at the bottom of the water tank.

[0020] 5. Under the work of the trapping motor of the device, the rotating plate drives multiple arc-shaped plates to continuously scoop up the impurities on the water surface towards the upper part of the collection bin. The water containing impurities enters the collection bin through the opening above the collection bin. Since the water level is lower than the bottom of the collection bin, the water re-enters the water tank through the water filtering holes, while the impurities remain inside the collection bin. Since the collection bin is inserted between multiple arc-shaped plates through the installation opening, when the crushing work is completed, the operator can conveniently take out the collection bin from the water tank through the handle for cleaning.

Specific embodiments

[0029] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] A system for recycling waste materials of polytetrafluoroethylene materials used in new energy vehicles, as Figures 1 - 7As shown, it includes a cooling unit 1 and a separation unit 7. The separation unit 7 includes a water tank 8. The cooling unit 1 is installed at one end of the top of the water tank 8. A bottom cover 4 that can be automatically opened is provided at the bottom of the cooling unit 1. A crushing unit 12 is provided below the bottom cover 4 in the upper part of the water tank 8. A bubble generating unit 17 is provided at the bottom of the water tank 8. A vibration guiding unit 21 is provided in the middle of the water tank 8. A trapping unit 26 for collecting dust and impurities is provided at one end of the water tank 8 away from the crushing unit 12.

[0032] The operator puts the relatively high-temperature polytetrafluoroethylene scraps into the cooling unit 1, and the scraps are preliminarily cooled by water. After the temperature of the scraps decreases, the bottom cover 4 at the bottom of the cooling unit 1 opens, and the scraps and water inside the cooling unit 1 fall into the crushing unit 12 inside the water tank 8. The water passes through the crushing unit 12 and falls into the water tank 8, while the scraps stay inside the crushing unit 12 for crushing. After the crushed qualified scraps pass through the crushing unit 12 and enter the vibration guiding unit inside the water tank 8. Since the vibration guiding unit is below the water level line, under the action of the vibration guiding unit, the scrap particles are continuously vibrated by the vibration guiding unit. At the same time, the bubble generating unit 17 at the bottom of the water tank 8 works, and the bubbles float from the bottom of the water tank 8 to the water surface, which is convenient to cooperate with the vibration guiding unit to improve the cleaning efficiency of the scrap particles. The scrap particles will pass through the vibration guiding unit and fall to the bottom of the water tank 8 under the vibration of the vibration guiding unit (the density of polytetrafluoroethylene is greater than that of water, so the scrap particles will sink to the bottom of the water tank). At this time, after being washed by water, the impurities and dust doped in the scrap particles float on the water surface. Through the work of the trapping unit 26, it is convenient to collect the impurities and dust on the water surface, which is convenient to separate the scrap particles and impurities, and realize the recycling of polytetrafluoroethylene scraps.

[0033] The cooling unit 1 includes a cooling box 2. The top and bottom of the cooling box 2 have openings respectively. A bottom cover 4 is installed at the opening at the bottom of the cooling box 2 through a spring hinge 5. A magnet 6 is provided at one end of the bottom cover 4 away from the spring hinge 5. The water tank 8 is made of metal. One end of the bottom cover 4 away from the spring hinge 5 is adsorbed and connected to the top of the water tank 8 through the magnet 6. A sealing strip is provided between the bottom cover 4 and the opening at the bottom of the cooling box 2. A water inlet pipe 3 is provided at the upper part of the side of the cooling box 2.

[0034] Since one end of the bottom cover 4 is connected to the bottom opening of the cooling box 2 through a spring hinge 5 (the spring hinge 5 is a prior art and is convenient for driving the bottom cover 4 to reset, so it will not be elaborated here), the other end of the bottom cover 4 is adsorbed and connected to the top of the water tank 8 through a magnet 6, and a sealing strip is provided at the bottom opening of the bottom cover 4 and the cooling box 2 to ensure the sealing performance at the bottom of the cooling box 2 when the water inlet pipe 3 injects water into the cooling box 2. Since scrap particles are placed inside the cooling box 2 and water for cooling is continuously injected into the cooling box 2, the pressure of the water and scrap inside the cooling box 2 on the bottom cover 4 continuously increases until the pressure is greater than the adsorption force between the magnet 6 and the water tank 8, and the bottom cover 4 can be automatically opened. Since water is continuously injected into the cooling box 2, the scrap can be cooled. When the water and scrap fall into the water tank 8, the pressure on the bottom cover 4 disappears, and under the action of the spring hinge 5, it can drive the bottom cover 4 to close again, ensuring that the magnet 6 is adsorbed on the water tank 8 again to cool the subsequent placed scrap.

[0035] The separation unit 7 includes a water tank 8. A spray head 11 is provided above the top of the water tank 8 and is located above the crushing unit 12. Water is filled inside the water tank 8. A water pump 9 is provided outside one end of the water tank 8 away from the cooling unit 1. The water pump 9 transports the water inside the water tank 8 to the water inlet pipe 3 and the spray head 11 respectively through a water delivery pipe 10. The crushing unit 12 includes a columnar filter screen 13. A crushing shaft 16 is provided at the axis of the filter screen 13. A plurality of groups of crushing knives 14 are arrayed on the crushing shaft 16. A crushing motor 15 for driving the crushing shaft 16 is provided outside the water tank 8. An opening is provided on the filter screen 13 near the bottom cover 4.

[0036] The horizontal height of the filter screen 13 is higher than the water level line inside the water tank 8. When the scrap and water fall from the cooling box 2 into the water tank 8, they first enter the inside of the filter screen 13 through the opening on the filter screen 13. The water will pass through the filter screen 13 and blend into the water inside the water tank 8, while the scrap will be intercepted by the filter screen 13. The crushing motor 15 is started, and the crushing knives 14 continuously crush the scrap, facilitating the crushing of the scrap into particles to pass through the filter screen 13. During the crushing process of the crushing knives 14, the water pump 9 works. The water pump 9 sends the water inside the water tank 8 into the spray head 11 through the water delivery pipe 10, and the spray head 11 continuously sprays water on the scrap particles inside the filter screen 13 for cooling, preventing the temperature from being too high when the crushing knives 14 crush the scrap particles and reducing the quality of the particles; the water pump 9 can also slowly inject water into the cooling box 2 through the water delivery pipe 10 to cool the scrap.

[0037] The bubble generating unit 17 includes an air chamber 18. The air chamber 18 is provided at the bottom of the water tank 8. A plurality of jet nozzles 19 are arrayed on the upper surface of the air chamber 18. An air compressor 20 communicated with the air chamber 18 is provided outside the water tank 8.

[0038] When the scrap particles fall into the water, the air compressor 20 works, continuously compressing gas into the inner part of the air chamber 18. The gas enters the bottom of the water tank 8 through the jet nozzle 19 to form bubbles. The bubbles will gradually increase during the rising process. When the bubbles burst, a strong impact force will be generated. This impact force can strip the dirt attached to the surface of the particles, thus achieving the cleaning effect.

[0039] The vibration guiding unit 21 includes a sieve plate 22. At the middle parts of both ends inside the water tank 8, limiting plates 23 are respectively arranged. The horizontal heights of the two limiting plates 23 are different. The horizontal height of the limiting plate 23 below the crushing unit 12 is higher than that of the other limiting plate 23. The bottom of the sieve plate 22 is obliquely arranged on the two limiting plates 23 through a return spring 24. A waterproof vibrator 25 is arranged at the bottom of the limiting plate 23. The power output end of the vibrator 25 works towards the sieve plate 22 through the limiting plate 23.

[0040] The scrap particles sinking into the water will first fall on the sieve plate 22. Through the work of the vibrator 25, the sieve plate 22 can vibrate, vibrating the scrap particles on the sieve plate 22. The scrap particles will pass through the sieve plate 22 and continue to fall towards the bottom of the water tank 8. However, the sieve plate 22 can slow down the falling speed of the scrap particles, and cooperate with the cleaning of the scrap particles by the bubbles to ensure the complete separation of the scrap particles from the impurities. Since the sieve plate 22 is obliquely arranged, it is convenient to drive the scrap particles towards the direction of the trapping unit 26 during vibration, avoiding the accumulation of scrap particles at the same position at the bottom of the water tank 8.

[0041] The top of the air chamber 18 is obliquely arranged. A discharge port 32 is arranged below the water tank 8 on the side close to the water pump 9. The horizontal height of the upper surface of the air chamber 18 gradually decreases towards the discharge port 32.

[0042] When the crushing work is completed, the water pump 9 stops working. By opening the discharge port 32, the water inside the water tank 8 can drive the scrap particles on the upper surface of the air chamber 18 at the bottom of the water tank 8 to be discharged from the discharge port 32. Through an external filtering device, it is convenient for the recycling work of the scrap particles and convenient for the subsequent reuse of the scrap particles.

[0043] Embodiment 2

[0044] On the basis of Embodiment 1, as Figure 5As shown, the trapping unit 26 includes a cylindrical collection bin 27. An installation opening is provided in the upper part of the side surface of the water tank 8. The collection bin 27 is arranged in the installation opening. An opening is provided in the upper part of the collection bin 27. Water filtering holes are formed in the bin wall of the collection bin 27. A trapping motor 29 is provided on one side of the water tank 8 opposite to the installation opening. A rotating plate 30 is arranged inside the water tank 8. The trapping motor 29 drives the rotating plate 30 to rotate. A plurality of arc-shaped plates 31 sleeved outside the collection bin 27 are arranged at the outer edge of the rotating plate 30. A handle 28 is provided at one end of the collection bin 27 away from the trapping motor 29. The water pump 9 is at the same horizontal height as the lowermost arc-shaped plate 31 on the rotating plate 30. The water level line inside the water tank 8 is higher than the horizontal height of the lowermost arc-shaped plate 31 on the rotating plate 30 and lower than the horizontal height of the bottom of the collection bin 27.

[0045] Since the scrap particles sink to the bottom of the water tank 8, while impurities such as dust float on the water surface. Since the water pump 9 is located at one end of the water tank 8 close to the trapping unit 26, under the operation of the water pump 9, the water inside the water tank 8 will move towards the direction of the water pump 9, thereby driving the impurities on the water surface to flow towards the trapping unit 26. Under the operation of the trapping motor 29, the rotating plate 30 drives the plurality of arc-shaped plates 31 to continuously scoop up the impurities on the water surface above the collection bin 27. The water containing impurities enters the collection bin 27 through the opening above the collection bin 27. Since the water level is lower than the bottom of the collection bin 27, the water re-enters the inside of the water tank 8 through the water filtering holes, while the impurities remain inside the collection bin 27. Since the collection bin 27 is inserted between the plurality of arc-shaped plates 31 through the installation opening, after the crushing work is completed, the operator can easily take out the collection bin 27 from the inside of the water tank 8 through the handle 28 for cleaning.

The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
