Description

Technical Field

[0001] The utility model belongs to the technical field of colloid particle coolers, in particular to a colloid particle cooler. Background Art

[0002] In the manufacturing process of rubber pellets, the temperature of the rubber pellets is high after forming and they need to be cooled by a cooler before they can be bagged. The main structure of the cooler is a rotatable drum made of metal. Inside the drum, there are a certain number and arrangement of copying plates along the axial direction. When the rubber pellets that need to be cooled are put into the drum from the feed end, the drum starts to rotate at a slow and stable speed under the drive of the motor. During the rotation of the drum, the copying plates set in the drum play a key role. These copying plates continuously pick up the rubber pellets. When the copying plates rotate to a certain height, the rubber pellets fall naturally under the action of gravity. Through this repetitive cycle of picking up and The sprinkling action maximizes the cooling efficiency. At the same time, in order to achieve effective cooling of the rubber particles, a cooling water tank is usually provided outside the drum. The coolant in the cooling water tank circulates continuously and continuously absorbs the heat conducted by the drum; or cooling air is introduced into the drum so that the cooling air is in full contact with the rubber particles and the inner wall of the drum. As the rubber particles roll and move with the rotation of the drum, the rubber particles and the drum wall continuously exchange heat. In this process, the heat carried by the rubber particles is continuously transferred to the drum wall, and the heat of the drum wall is quickly taken away by the coolant in the external cooling water tank or the cooling air introduced, so that the temperature of the rubber particles gradually decreases.

[0003] The shortcomings of the existing pellet cooler are: it needs to be equipped with a complete set of water circulation system to achieve the circulating cooling effect. The construction, installation and subsequent maintenance costs of this water circulation system are high. In addition, the construction of the cooling pool requires a large amount of space and a large amount of construction funds. These factors directly lead to a significant increase in equipment costs and production costs. In actual production, it is often necessary to cool only a small number of pellets. However, even under such conditions with a small processing volume, it is still necessary to start the entire huge water circulation system to maintain the cooling operation. Since the various components of the water circulation system, such as water pumps, cooling pools, etc., need to run at full load or close to full load regardless of the processing volume, this will undoubtedly greatly increase the power consumption of the equipment and cause unnecessary energy waste. In the long run, it not only increases the production and operation costs of the enterprise, but also runs counter to the current development concept of energy conservation and environmental protection. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a pellet cooler, comprising a cooling wind tower and an air cooling structure located on the left side of the cooling wind tower, and a heat conduction and heat dissipation structure located below the cooling wind tower and connected to the cooling wind tower;

[0005] The air cooling structure includes an air pump and a transmission pipe connected to the output end of the air pump, and a discharge hopper and a connecting pipe located above the transmission pipe, wherein the discharge hopper and the connecting pipe are both connected to the transmission pipe;

[0006] The heat conduction and heat dissipation structure includes a collecting barrel and a conductive thin plate assembled on the inner wall of the collecting barrel, and a heat dissipation copper tube located outside the conductive thin plate. The outer wall of the collecting barrel is provided with a heat dissipation groove for the heat dissipation copper tube.

[0007] Preferably, the outer wall of the cooling tower is provided with equidistantly distributed heat dissipation holes, and the diameter of the heat dissipation holes is two millimeters.

[0011] Preferably, electromagnetic valves for unloading are provided inside the unloading pipe and the discharge hopper.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model cooperates the air cooling structure with the heat conduction heat dissipation structure to dissipate heat for the formed rubber particles, only needs to start the air pump, and the air pump blows the rubber particles in the discharge hopper to the connecting pipe through the transmission pipe, and then the rubber particles reach the cooling air tower through the connecting pipe. Under the action of the continuous operation of the air pump, a steady stream of gas and the rubber particles quickly rush to the cooling air tower. In this process, the heat emitted by the rubber particles themselves can flow out through the heat dissipation punching holes of the cooling air tower under the drive of the high-speed circulating gas, thereby achieving initial cooling. Since the volume of the rubber particles themselves is larger than the diameter of the heat dissipation punching holes, the rubber particles will not be blown out of the cooling air tower. After the first heat dissipation, the rubber particles enter the collecting barrel through the discharge pipe. At this stage, the conductive thin plate and the heat dissipation copper pipe play a role. Since the copper pipe itself has good thermal conductivity, it exchanges heat with the surrounding air, thereby achieving secondary cooling. In this way, when there are fewer rubber particles that need to be cooled, the energy consumption generated in the cooling process is greatly reduced, and the cost is effectively reduced.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the utility model provides a pellet cooler, comprising a cooling tower 1, an air cooling structure 2 located on the left side of the cooling tower 1, and a heat conduction and heat dissipation structure 3 located below the cooling tower 1 and connected to the cooling tower 1;

[0022] The air cooling structure 2 includes an air pump 21 and a transmission pipe 22 connected to the output end of the air pump 21, and a discharge hopper 23 and a connecting pipe 24 located above the transmission pipe 22. The discharge hopper 23 and the connecting pipe 24 are both connected to the transmission pipe 22.

[0023] The heat conduction and heat dissipation structure 3 includes a collecting barrel 31 and a conductive thin plate 32 assembled on the inner wall of the collecting barrel 31, and a heat dissipation copper tube 33 located outside the conductive thin plate 32. The outer wall of the collecting barrel 31 is provided with a heat dissipation groove 311 for the heat dissipation copper tube 33 to dissipate heat.

[0024] The above solution is adopted: when the formed rubber pellets are cooled by the air cooling structure 2 in conjunction with the heat conduction heat dissipation structure 3, it is only necessary to start the air pump 21. The air pump 21 blows the rubber pellets in the discharge hopper 23 to the connecting pipe 24 through the transmission pipe 22. Then the rubber pellets reach the cooling tower 1 through the connecting pipe 12. Under the action of the continuous operation of the air pump 21, a steady stream of gas and rubber pellets quickly rushes to the cooling tower 1. In this process, the heat emitted by the rubber pellets themselves can be driven by the high-speed circulating gas to pass through the heat dissipation punching 1 of the cooling tower 1. 1 flows out, thereby achieving preliminary cooling. Since the volume of the rubber particles themselves is larger than the diameter of the heat dissipation punching 11, the rubber particles will not be blown out of the cooling wind tower 1. After the primary heat dissipation, the rubber particles enter the collecting barrel 31 through the discharge pipe 35. At this stage, the conductive sheet 32 and the heat dissipation copper tube 33 play a role. Since the copper tube itself has good thermal conductivity, it exchanges heat with the surrounding air, thereby achieving secondary cooling. In this way, when there are fewer rubber particles that need to be cooled, the energy consumption generated in the cooling process is greatly reduced, and the cost is effectively reduced.

[0025] like Figures 1 to 5 As shown, the outer wall of the cooling wind tower 1 is provided with evenly spaced heat dissipation holes 11, the diameter of the heat dissipation holes 11 is two millimeters, the outside of the cooling wind tower 1 is fixedly connected to a support frame 4, the top of the cooling wind tower 1 is connected to a connecting pipe 12, and the top of the connecting pipe 12 is connected to the other end of the connecting pipe 24.

[0026] The above solution is adopted: the diameter of the heat dissipation punching hole 11 is set to two millimeters in order to reduce the problem of the particles flowing out through the heat dissipation punching hole 11 under the circulation of gas. The cooling wind tower 1 is supported by the support frame 4 to increase its stability during operation and fix the position of the cooling wind tower 1.

[0027] like Figures 1 to 5 As shown, the heat dissipation copper tubes 33 are distributed in a circular array with the axis point of the collecting barrel 31 as the center point. The bottom of the collecting barrel 31 is connected to the discharge hopper 34, and the collecting barrel 31 is connected to the middle of the cooling tower 1 through a discharge pipe 35.

[0028] With the above solution, even after the initial cooling of the pellets, there may still be some residual heat. In this case, the heat dissipation copper tube 33 and the conductive sheet 32 begin to play their important role. The heat dissipation copper tube 33 and the conductive sheet 32 are made of materials with excellent thermal conductivity. Their unique physical properties enable them to quickly and efficiently absorb the remaining heat from the pellets. As heat is continuously absorbed, the temperature of the heat dissipation copper tube 33 and the conductive sheet 32 gradually increases. At the same time, because they are always in contact with the outside air, a significant temperature difference is formed between the higher temperature heat dissipation copper tube 33 and the conductive sheet 32 and the surrounding cold air. Based on the principle of heat exchange, heat is naturally transferred from the higher temperature heat dissipation copper tube 33 and the conductive sheet 32 surface to the lower temperature outside air. During this heat exchange process, the heat absorbed by the heat dissipation copper tube 33 and the conductive sheet 32 is continuously dissipated to the outside, and the air continuously carries away this heat, achieving an effective heat conduction cooling effect.

[0029] like Figures 1 to 5 As shown, electromagnetic valves for unloading are provided inside the unloading pipe 35 and the discharge hopper 34 .

[0030] Using the above solution: the electromagnetic valve at the discharge pipe 35 can control the rubber particles to enter the collecting barrel 31 from the cooling wind tower 1, and the electromagnetic valve at the discharge hopper 34 can control the material to flow through the collecting barrel 31 to the discharge hopper 34 and out through the discharge hopper 34.

[0031] The working principle and use process of this utility model:

[0032] First, the rubber particles are poured into the discharge hopper 23, and then the air pump 21 is started. At this time, the strong wind force generated by the air pump 21 blows the rubber particles in the discharge hopper 23 to the connecting pipe 24 through the transmission pipe 22, and then the rubber particles reach the cooling wind tower 1 through the connecting pipe 12. Under the action of the continuous operation of the air pump 21, the rubber particles quickly rush to the cooling wind tower 1 together. In this process, the heat emitted by the rubber particles themselves can flow out through the heat dissipation punching 11 of the cooling wind tower 1 under the action of the high-speed circulation of gas, thereby achieving preliminary cooling. After the first heat dissipation, the rubber particles enter the collecting barrel 31 through the discharge pipe 35. At this stage, the conductive sheet 32 and the heat dissipation copper pipe 33 play a role. Since the copper pipe itself has good thermal conductivity, it exchanges heat with the surrounding air, thereby achieving secondary cooling. Finally, a collection bag is placed under the discharge hopper 34 and the electromagnetic valve at the discharge hopper 34 is opened, so that the rubber particles fall into the collection bag through the discharge hopper 34 for bagging.
