Description

Technical Field

[0001] This utility model relates to the field of water ring pelletizers, and in particular to a water cooling circulation device for TPV elastomers. Background Technology

[0002] Thermoplastic vulcanizate, abbreviated as TPV, is mainly composed of two parts: plastic as the continuous phase and rubber as the dispersed phase. It has excellent dynamic fatigue resistance, high tear resistance, excellent weather resistance, good wear resistance, and excellent flame retardancy and UV resistance. It also has excellent resistance to water-based acid and alkali liquids and polar oils. It is widely used in the automotive parts, electronics and electrical, sporting goods, wire and cable and other industries.

[0003] TPV materials are typically first processed into elastomer granules, which are then used as raw materials for finished product manufacturing. During TPV elastomer processing, the TPV material is usually heated to a molten state in an extruder and continuously extruded through extrusion orifices into a water chamber. A pelletizer then cuts the extruded molten material in the water chamber, and the cut molten material rapidly cools and solidifies in water to form TPV elastomer granules, which are then transported away by a flowing water stream. After the TPV elastomer granules are recovered, the water in the transport stream is usually collected and pumped back into the water chamber for recycling. As the molten TPV material continues to release heat and solidify in the water chamber, the water temperature gradually rises, which can affect the curing effect of the TPV material and may even cause the water in the water chamber to boil, affecting production safety.

[0004] Existing water-cooling circulation devices for TPV elastomer particles typically employ large-capacity circulating water tanks to slow down the rise in water temperature by extending the cooling water circulation cycle. However, increasing the water volume has limited effect in delaying the temperature rise. When the pelletizer operates for extended periods or under high loads, the cooling water temperature can still rise to a high level, affecting the cooling and curing effect on the TPV elastomer particles.

[0009] Furthermore, the cooling water tank is provided with a first partition and a second partition spaced apart.

[0010] Preferably, a water supply interface is provided at the upper part of the isolation chamber, and a water supply valve is provided on the water supply interface.

[0011] Preferably, the bottom of the convection cooling chamber is provided with a support foot, the bottom wall of the convection cooling chamber is provided on the support foot, a convection space is formed below the bottom wall of the convection cooling chamber, and a plurality of convection slots are provided on the convection cooling chamber, penetrating the bottom and top walls of the convection cooling chamber, and the convection cooling chamber space outside the convection slots forms a convection cooling channel.

[0012] More preferably, a plurality of flow channel baffles are provided in the convection cooling chamber outside the convection slot hole, the plurality of flow channel baffles are spaced apart, and baffle channels are alternately provided at opposite ends of adjacent flow channel baffles.

[0013] Furthermore, the plurality of convection slots are arranged in parallel, and the length direction of the baffle channel is perpendicular to the length direction of the convection slots.

[0014] Preferably, the upper part of the heat equalization buffer chamber is provided with a circulating water interface, and the circulating water pipe is connected to the circulating water interface.

[0015] Preferably, the lower part of the heat equalization buffer chamber is provided with a drain interface, and a drain valve is provided on the drain interface.

[0016] The water-cooled circulation device for TPV elastomer particles of this invention has at least one of the following beneficial technical effects:

[0017] 1. By using the convection cooling chamber installed in the cooling water tank, the cooling water can be cooled by air convection during the cooling water circulation process, so that the heat in the cooling water can be dissipated into the air more quickly. The large capacity of water stored in the heat equalization buffer chamber buffers the stable rise of the cooling water, thereby reducing the temperature of the cooling water circulating into the water chamber and improving the cooling and curing effect of the TPV elastomer particles in the water chamber.

[0018] 2. By using a diversion mechanism and a filter chamber located between the particle-water separation mechanism and the convection cooling chamber, the heat dissipation in the flowing water is promoted during the diversion of the higher-temperature cooling water separated from the conveying water flow, and TPV elastomer fragments in the water are filtered out. This improves water flow and cooling effect while better reducing water temperature.

[0019] 3. By utilizing the convection slots that penetrate the bottom and top walls of the convection cooling chamber, multiple air convection channels can be formed inside the chamber. During air convection, heat exchange occurs between the water in the chamber and the walls of the convection slots, improving the cooling effect of the water flowing within the chamber. Furthermore, the multiple flow channel baffles installed within the chamber allow the water to flow repeatedly across the walls of the convection slots, resulting in multiple and thorough contacts with the slot walls and enhancing the heat exchange effect.

[0020] 4. By having the length direction of the baffle channel perpendicular to the length direction of the convection slot holes, the number of convection slot holes that the water in the convection cooling chamber comes into contact with when flowing between the cross baffles of the flow channel, and the contact time with the hole walls of the convection slot holes, can be increased. This reduces the water flow resistance while improving the heat exchange effect between the water and the hole walls of the convection slot holes, and the cooling effect of the cooling water.

[0026] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] One embodiment of the water-cooled circulation device for TPV elastomers of this utility model is as follows: Figure 1 and Figure 2 As shown, the device includes a pelletizer water chamber 1, a hydraulic conveying pipe 2, a pellet-water separation mechanism 3, a cooling water tank 4, a circulating water pipe 5, and a circulating water pump 6. The pelletizer water chamber 1 is filled with cooling water, which is used to cool the molten TPV material cut in the water chamber, so that it solidifies to form TPV elastomer particles.

[0029] The hydraulic conveying pipe 2 is connected to the lower part of the water chamber 1 of the pelletizer. TPV elastomer particles enter the hydraulic conveying pipe 2 with the cooling water flow and are conveyed forward in the hydraulic conveying pipe 2. The other end of the hydraulic conveying pipe 2 is connected to the particle-water separation mechanism 3. The TPV elastomer particles enter the particle-water separation mechanism 3 with the water flow and are separated from the water in the particle-water separation mechanism 3. The TPV elastomer particles remain in the particle-water separation mechanism 3 and are output from the particle output port on the particle-water separation mechanism 3; the cooling water is separated from the particle-water separation mechanism 3.

[0030] A particle-water separation mechanism 3 is positioned above the cooling water tank 4. The circulating cooling water separated from the particle-water separation mechanism 3 enters the cooling water tank 4. The cooling water tank 4 is equipped with a convection cooling chamber 41 and a heat exchange buffer chamber 42. The convection cooling chamber 41 has a convection cooling structure that utilizes air convection to cool the cooling water within it. The cooling water separated from the particle-water separation mechanism 3 first enters the convection cooling chamber 41, where it exchanges heat with the air through the convection cooling structure and dissipates heat from the cooling water into the air, thus lowering the temperature of the cooling water. The heat exchange buffer chamber 42 is connected to the outlet of the convection cooling chamber 41. It contains a larger quantity of cooling water, which mixes with the cooling water from the convection cooling chamber 41, slowing down the temperature rise of the cooling water in the heat exchange buffer chamber 42.

[0031] One end of the circulating water pipe 5 is connected to the homogenizing buffer chamber 42, and the other end is connected to the upper side of the pelletizer water chamber 1. A circulating water pump 6 is installed on the circulating water pipe 5. The circulating water pump 6 can circulate the cooled water in the homogenizing buffer chamber 42 into the pelletizer water chamber 1, continuously circulating and cooling the TPV elastomer particles in the pelletizer water chamber 1, improving the cooling and solidification effect of the TPV elastomer particles in the water chamber. At the same time, the cooling water continuously entering the pelletizer water chamber 1 can also drive the original heated cooling water in the pelletizer water chamber 1 to flow out through the hydraulic conveying pipe 2, driving the TPV elastomer particles to be continuously output along with the cooling water flow through the hydraulic conveying pipe 2.

[0032] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, a diversion mechanism 43 and a filter chamber 44 are provided below the particle-water separation mechanism 3 and between it and the convection cooling chamber 41. The diversion mechanism 43 can be a diversion trough. The diversion mechanism 43 is located below the particle-water separation mechanism 3 and is used to collect the high-temperature cooling water discharged from the particle-water separation mechanism 3 and divert the cooling water to the filter chamber 44 to cool the cooling water during the flow process.

[0033] A filter screen 441 is installed at the top opening of the filter chamber 44. Circulating cooling water, guided by the flow-inducing mechanism 43, flows onto the filter screen 441. The filter screen 441 filters out TPV elastomer fragments and other solid impurities mixed in with the cooling water. The cooling water passes through the filter screen and flows into the filter chamber 44, where it is slowly cooled by sufficient contact with the air during the filtration process. The filter chamber 44 is connected to a convection cooling chamber 41, where the higher-temperature circulating cooling water flows into the convection cooling chamber 41 for further cooling.

[0034] In a further preferred embodiment, such as Figure 2 and Figure 3 As shown, a cleaning chamber 45 is also provided between the convection cooling chamber 41 and the heat equalization buffer chamber 42. The cleaning chamber 45 includes a sedimentation chamber 451 adjacent to the convection cooling chamber 41 and an isolation chamber 452 adjacent to the heat equalization buffer chamber 42. The cleaning chamber is used to isolate and remove high-density impurities in the circulating cooling water. The bottom of the convection cooling chamber 41 is connected to the sedimentation chamber 451. The circulating cooling water enters the bottom of the sedimentation chamber 451 from the bottom of the convection cooling chamber 41 and flows upward from the bottom. The high-density impurities in the circulating cooling water are deposited at the bottom of the sedimentation chamber 451.

[0035] A cleaning baffle 453 is provided between the sedimentation chamber 451 and the isolation chamber 452. The bottom edge and both sides of the cleaning baffle 453 are connected to the wall of the cleaning chamber 45, preventing circulating cooling water and high-density impurities mixed in it from entering the isolation chamber 452 from the bottom. The sedimentation chamber 451 and the isolation chamber 452 are connected above the cleaning baffle 453. When the water level of the circulating cooling water in the sedimentation chamber 451 rises to the top height of the cleaning baffle 453, the circulating cooling water will overflow the cleaning baffle 453 and enter the isolation chamber 452.

[0036] The bottom of the isolation chamber 452 is connected to the heat equalization buffer chamber 42. The circulating cooling water in the isolation chamber 452 enters the heat equalization buffer chamber 42 through the bottom channel. The low-density impurities floating on the water surface are blocked by the side wall of the heat equalization buffer chamber 42 and remain in the isolation chamber 452, which improves the purity of the circulating cooling water entering the heat equalization buffer chamber 42.

[0037] As one specific implementation method, such as Figure 2 and Figure 3 As shown, a first partition 46 and a second partition 47 are spaced apart inside the cooling water tank 4. The first partition 46 and the second partition 47 are arranged parallel to each other inside the cooling water tank 4, dividing the cooling water tank 4 into a heat dissipation buffer chamber 42 located on one side of the first partition 46, an intermediate chamber located between the first partition 46 and the second partition 47, and a convection cooling chamber 41 located on the other side of the second partition 47. A transverse partition 48 is provided at a position slightly above the intermediate chamber, dividing the intermediate chamber into a filter chamber 44 located above the transverse partition 48 and a cleaning chamber 45 located below the transverse partition 48.

[0038] A support frame 49 is provided above the side wall of the cooling water tank 4 at the other end of the first partition 46 and the heat equalization buffer chamber 42. The particle-water separation mechanism 3 includes a circular centrifugal separation tank 31 and a water-dividing feed hopper 32 fixed on the bottom side wall of the centrifugal separation tank 31. The centrifugal separation tank 31 is mounted on the support frame 49, and the hydraulic conveying pipe 2 is connected to the water-dividing feed hopper 32. TPV elastomer particles transported by water flow enter the water-dividing feed hopper 32 through the hydraulic conveying pipe 2. Part of the circulating cooling water flows directly to the filter screen plate 441 through the water-dividing holes at the bottom of the water-dividing feed hopper 32; the remaining circulating cooling water and TPV elastomer particles enter the centrifugal separation tank 31 for centrifugal separation. The TPV elastomer particles are discharged through the discharge port at the top of the centrifugal separation tank 31, and the circulating cooling water flows out from the bottom of the centrifugal separation tank 31.

[0039] The flow guiding mechanism 43 is inclinedly arranged below the centrifugal separation tank 31. It is connected to the upper part of the first partition 46 and the second partition 47 on both sides of the filter screen plate 441 respectively. A first flow guiding hole 461 is provided on the first partition 46 above the filter screen plate 441. The lower end of the flow guiding mechanism 43 is fixed below the other side of the first flow guiding hole 461. The circulating cooling water flowing out from the bottom of the centrifugal separation tank 31 falls into the flow guiding mechanism 43 and flows through the first flow guiding hole 461 to the filter screen plate 441. After being filtered by the filter screen plate 441, it flows into the filter chamber 44.

[0040] A second drainage hole 471 is provided on the second partition 47 above the transverse partition 48. The second drainage hole 471 connects the filter chamber 44 and the convection cooling chamber 41. The circulating cooling water in the filter chamber 44 enters the convection cooling chamber 41 through the second drainage hole 471 for cooling.

[0041] By removing the filter screen 441 and the partition plate 48, the sedimentation chamber 451 and the isolation chamber 452 can be cleaned, removing the circulating cooling water and impurities from the sedimentation chamber 451 and the isolation chamber 452, and cleaning the sedimentation chamber 451 and the isolation chamber 452.

[0042] In one embodiment, such as Figure 2 and Figure 3 As shown, a water supply port 454 is provided on the upper part of the side wall of the isolation chamber 452. The water supply port 454 is connected to the isolation chamber 452, and new circulating cooling water can be added to the isolation chamber 452 through the water supply port 454 to ensure that the amount of circulating cooling water meets the cooling and transportation needs of the TPV elastomer particles. A water supply valve 455 is provided on the water supply port 454. The water supply valve 455 can be used to close the water supply port 454, stop the replenishment of circulating cooling water into the isolation chamber 452, and prevent the circulating cooling water in the isolation chamber 452 from leaking through the water supply port 454.

[0043] In a preferred embodiment, a support foot 411 is provided at the bottom of the convection cooling chamber 41, and the bottom wall of the convection cooling chamber 41 is set on the support foot 411, so that the bottom wall of the convection cooling chamber 41 is a certain distance away from the ground, forming a convection space below the bottom wall of the convection cooling chamber 41 that is conducive to airflow. Multiple convection slots 412 are provided inside the convection cooling chamber 41, penetrating the bottom and top walls of the convection cooling chamber 41. The walls of the convection slots 412 are made of a material with high thermal conductivity, such as metal. The walls of the convection slots 412 are fixedly connected to and sealed to the surrounding convection cooling chambers 41, so that the space inside the convection cooling chambers 41 outside the convection slots 412 forms a convection cooling channel that is isolated from the convection slots 412. The high-temperature circulating cooling water entering the convection cooling chamber 41 flows in the convection cooling channel, transferring heat to the convection slot 412. The air in the convection slot 412 is heated and rises to form convection, improving the heat dissipation effect of the circulating cooling water in the convection cooling channel.

[0044] In a preferred embodiment, such as Figures 2 to 4 As shown, multiple flow channel baffles 413 are arranged in the convection cooling chamber 41 outside the convection slot hole 412. These baffles 413 are spaced apart within the convection cooling chamber 41, dividing the convection cooling channels into multiple layers. A baffle channel 414 is provided on one side of each flow channel baffle 413, allowing circulating cooling water flowing on each baffle 413 to flow into the convection cooling channel below that baffle 413 through the baffle channel 414. The baffle channels 414 on adjacent flow channel baffles 413 are located on opposite sides of the baffles, causing the circulating cooling water flowing into the next layer of convection cooling channel to flow in the opposite direction, contacting the wall of the convection slot hole 412 again for convection cooling. This multi-layered convection cooling channel system improves the cooling effect of the circulating cooling water within the convection cooling chamber 41.

[0045] In a further preferred embodiment, such as Figures 2 to 4 As shown, multiple convection slots 412 are arranged parallel to each other at equal intervals within the convection cooling chamber 41. Baffle channels 414 on each flow channel partition 413 are located on both sides of the length of the convection slot 412, and the length direction of the baffle channels 414 is perpendicular to the length direction of the convection slot 412. In this way, the circulating cooling water entering the convection cooling chamber 41 flows along the length of the convection slots 412 between the multiple convection slots 412, maintaining prolonged and sufficient contact with the walls of the multiple convection slots 412, thus improving the heat transfer effect with the convective air within the convection slots 412. The circulating cooling water repeatedly turns back as it flows from the top to the bottom of the convection cooling chamber 41, further increasing the contact and heat exchange time with the walls of the convection slots 412, further improving the heat dissipation effect of the circulating cooling water within the convection cooling chamber 41.

[0046] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a circulating water interface 421 is provided at the upper part of the heat equalization buffer chamber 42. The circulating water pipe 5 is connected to the circulating water interface 421. After cooling and cleaning, the circulating cooling water is drawn into the pelletizer water chamber 1 through the circulating water pipe 5 to cool and transport the TPV elastomer particles. Placing the circulating water interface 421 at the upper part of the heat equalization buffer chamber 42 can reduce the chance of impurities in the circulating cooling water entering the circulating water pipe 5.

[0047] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a drain port 422 is provided at the lower part of the homogenization buffer chamber 42. The drain port 422 can be connected to the sewage discharge port through a drain pipe. A drain valve 423 is provided on the drain port 422. After the pelletizer finishes working, the drain valve 423 can be opened to drain the circulating cooling water that has accumulated turbidity over time and replace it with fresh circulating cooling water for cooling and conveying the TPV elastomer particles. The drain port 422 is usually located at the bottom of the homogenization buffer chamber 42, which facilitates the drainage of the circulating cooling water in the homogenization buffer chamber 42.

[0048] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
