Description

Technical Field

[0001] This application relates to the field of internal mixer technology, and more specifically, to a high-efficiency cooling circulation device for a rubber compound internal mixer. Background Technology

[0002] In the production of polymer materials such as rubber and plastics, the internal mixer plays a crucial role. Through intense stirring and kneading, the internal mixer ensures that various compounding agents are evenly dispersed within the rubber or plastic matrix, thereby improving the overall performance of the material. However, the mixing process generates a significant amount of heat; if this heat is not removed promptly and effectively, it can lead to a series of problems.

[0003] Traditional internal mixers mostly use air cooling or water cooling. While air cooling can achieve a certain degree of cooling, it also releases irritating gases remaining inside the rubber mixer, making it easy for workers to inhale them and seriously threatening their health. As for circulating cooling, existing rubber internal mixers cannot achieve effective circulating cooling, requiring workers to frequently go back and forth to add coolant to the cooling system. This is not only cumbersome and labor-intensive, but also greatly reduces the cooling efficiency of the mixer, thus affecting the overall production process and efficiency. Utility Model Content

[0004] To address the aforementioned issues, this application provides a high-efficiency cooling circulation device for a rubber compound internal mixer.

[0005] The technical solution provided in this application for a high-efficiency cooling circulation device for a rubber compound internal mixer is as follows:

[0006] A high-efficiency cooling circulation device for a rubber compound internal mixer includes a mixing chamber, and a cooling circulation component is provided at one end of the mixing chamber;

[0007] The cooling circulation assembly includes a cooling pipe located at the rear of the mixing chamber. A water pump is located at one end of the mixing chamber, and one end of the cooling pipe is connected to the water pump. A cooling water tank is located in front of the water pump, and a connecting pipe connects the water pump and the cooling water tank. Both ends of the connecting pipe are connected to the water pump and the cooling water tank.

[0008] Through the above technical solution, components such as cooling pipes, water pumps, cooling water tanks, circulating pumps, and coolers form a circulating cooling system. The coolant continuously circulates and can effectively remove the heat generated in the mixing chamber. Compared with traditional cooling methods, this greatly improves cooling efficiency, ensures that the mixing process is carried out at a suitable temperature, and guarantees the quality of the compound.

[0009] Furthermore, a circulation pump is installed on the side of the mixing chamber away from the water pump, and both ends of the circulation pump are connected to pipes.

[0010] Furthermore, one end of one of the pipes is connected to the cooling water tank, and a cooler is provided on the front side of the circulating pump.

[0011] Furthermore, one end of another pipe is connected to the cooler, and the end of the cooling pipe away from the water pump is connected to the cooler.

[0012] Furthermore, heat dissipation plates are installed on both sides of the mixing chamber to assist in heat dissipation.

[0013] Through the above technical solution, the heat dissipation plate increases the heat dissipation area, enabling the mixing chamber to dissipate heat to the outside through a larger surface area.

[0014] Furthermore, an inlet pipe is connected to one end of the cooling water tank, and an outlet pipe is connected to the other end of the cooling water tank.

[0015] Furthermore, both the inlet and outlet water pipes are equipped with solenoid valves, and a controller is located on one side of the mixing chamber.

[0016] With the above technical solution, after the cooling circulation device has been used for a period of time, the coolant temperature may be too high or the water level may be too low. The controller will then control the solenoid valve in the outlet pipe to open, and the excess coolant will be discharged through the outlet pipe. Subsequently, the controller will send an opening signal to the solenoid valve in the inlet pipe, and the external water source will flow into the cooling water tank through the inlet pipe to replenish the coolant.

[0017] Furthermore, the top of the mixing chamber is connected to a feeding chamber, and the top of the feeding chamber has a feeding port. The controller is electrically connected to the mixing chamber, water pump, solenoid valve, circulating pump and cooler.

[0018] Through the above technical solution, the controller receives feedback signals from the mixing chamber, cooling water tank and other parts, and accordingly coordinates and regulates the working status of the mixing chamber, as well as the operation of the water pump, solenoid valve, circulating pump and cooler, to ensure the stability of the cooling and mixing process.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) This utility model forms a circulating cooling system by means of components such as cooling pipe, water pump, cooling water tank, circulating pump and cooler. The coolant continuously circulates and can continuously and effectively remove the heat generated in the mixing chamber. Compared with the traditional cooling method, it greatly improves the cooling efficiency, ensures that the mixing process is carried out at a suitable temperature, and guarantees the quality of the mixed rubber.

[0021] (2) The heat dissipation plate of this utility model increases the heat dissipation area, enabling the mixing chamber to dissipate heat to the outside through a larger surface area.

[0022] (3) This utility model can automatically respond to situations where the coolant temperature is too high or the water level is too low. When the temperature is too high, some hot water is discharged and cold water is added, which can quickly reduce the coolant temperature and ensure that it always has good cooling capacity. This maintains the cooling circulation system's stable cooling effect on the mixing chamber, thereby ensuring that the quality of the compound is not affected by temperature fluctuations.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-4 A high-efficiency cooling circulation device for a rubber compound internal mixer includes a mixing chamber 1, and a cooling circulation component is provided at one end of the mixing chamber 1;

[0030] The cooling circulation assembly includes a cooling pipe 4, which is located at the rear of the mixing chamber 1. A water pump 5 is provided at one end of the mixing chamber 1. One end of the cooling pipe 4 is connected to the water pump 5. A cooling water tank 6 is provided in front of the water pump 5. A connecting pipe 7 is connected between the water pump 5 and the cooling water tank 6. Both ends of the connecting pipe 7 are connected to the water pump 5 and the cooling water tank 6.

[0031] During the mixing process, the mixing chamber 1 generates heat, activating the cooling circulation assembly. Water pump 5 starts, drawing water from the cooling water tank 6 through connecting pipe 7 and delivering it to cooling pipe 4. Cooling pipe 4 is located at the rear of the mixing chamber 1, where coolant flows, absorbing the heat generated by the mixing chamber 1 and achieving initial cooling.

[0032] After absorbing heat, the hot water flows out from the other end of the cooling pipe 4 and flows to the cooler 11. At the same time, the circulating pump 10 works to draw out the cold water in the cooling water tank 6 through the pipe body 9. A portion of the cold water is transported through the pipe body 9 to the cooler 11 to exchange heat with the hot water flowing out from the cooling pipe 4. After being cooled down in the cooler 11, the hot water flows back to the cooling water tank 6 through the pipe body 9 for recycling.

[0033] A circulating cooling system is formed by components such as cooling pipe 4, water pump 5, cooling water tank 6, circulating pump 10 and cooler 11. The coolant circulates continuously and can effectively remove the heat generated in the mixing chamber 1. Compared with traditional cooling methods, the cooling efficiency is greatly improved, ensuring that the mixing process is carried out at a suitable temperature and guaranteeing the quality of the mixed rubber.

[0034] Reference Figures 1-4 A circulating pump 10 is provided on the side of the mixing chamber 1 away from the water pump 5. Both ends of the circulating pump 10 are connected to pipes 9. One end of one pipe 9 is connected to the cooling water tank 6. A cooler 11 is provided on the front side of the circulating pump 10. One end of the other pipe 9 is connected to the cooler 11. The end of the cooling pipe 4 away from the water pump 5 is connected to the cooler 11.

[0035] Reference Figures 1-2 The mixing chamber 1 has heat dissipation plates 12 on both sides, which are used to assist in heat dissipation.

[0036] When the internal mixer is operating, a large amount of heat is generated inside the mixing chamber 1 due to the mixing process of the rubber compound. At this time, not only is the coolant in the cooling circulation assembly playing a role, but the heat dissipation plates 12 on both sides of the mixing chamber 1 also participate in heat dissipation simultaneously. The heat in the mixing chamber 1 is transferred to the heat dissipation plates 12, which are in close contact with it, through heat conduction. Because the heat dissipation plates 12 have a large surface area, the heat can be quickly dissipated from the surface of the heat dissipation plates 12 into the surrounding air, thereby assisting the cooling circulation assembly and further reducing the temperature of the mixing chamber 1.

[0037] The heat dissipation plate 12 increases the heat dissipation area, enabling the mixing chamber 1 to dissipate heat to the outside through a larger surface area.

[0038] Reference Figures 1-4 One end of the cooling water tank 6 is connected to an inlet pipe 13, and the other end of the cooling water tank 6 is connected to an outlet pipe 14. Both the inlet pipe 13 and the outlet pipe 14 are equipped with solenoid valves 8. A controller is provided on one side of the mixing chamber 1.

[0039] After the cooling circulation device has been used for a period of time, the coolant temperature may be too high or the water level may be too low. The controller will then open the solenoid valve 8 in the outlet pipe 14, and the excess coolant will be discharged through the outlet pipe 14. Subsequently, the controller will send an opening signal to the solenoid valve 8 in the inlet pipe 13, and the external water source will flow into the cooling water tank 6 through the inlet pipe 13 to replenish the coolant.

[0040] Reference Figures 1-4 The top of the mixing chamber 1 is connected to the feeding chamber 2, and the top of the feeding chamber 2 is provided with the feeding port 3. The controller is electrically connected to the mixing chamber 1, the water pump 5, the solenoid valve 8, the circulating pump 10 and the cooler 11.

[0041] The material enters the feeding chamber 2 through the feed inlet 3, and then enters the mixing chamber 1. The controller receives feedback signals from the mixing chamber 1, cooling water tank 6, and other parts, and accordingly coordinates and regulates the working status of the mixing chamber 1, as well as the operation of the water pump 5, solenoid valve 8, circulating pump 10, and cooler 11 to ensure the stability of the cooling and mixing process.

[0042] Working principle: The material first enters the feeding chamber 2 through the feed inlet 3, and then enters the mixing chamber 1 to begin mixing. During the mixing process, the mixing chamber 1 generates a large amount of heat, at which point the cooling circulation assembly is activated. The water pump 5 starts, drawing water from the cooling water tank 6 through the connecting pipe 7, and delivering the coolant to the cooling pipe 4 located at the rear of the mixing chamber 1. The coolant flows in the cooling pipe 4, absorbing the heat from the mixing chamber 1, achieving initial cooling.

[0043] After absorbing heat, the hot water flows out from the other end of the cooling pipe 4 and towards the cooler 11. Simultaneously, the circulating pump 10 operates, drawing cold water from the cooling water tank 6 through the pipe body 9. A portion of this cold water is transported through the pipe body 9 to the cooler 11, where it exchanges heat with the hot water flowing out from the cooling pipe 4. After being cooled in the cooler 11, the hot water flows back to the cooling water tank 6 through the pipe body 9 for reuse. Thus, the cooling pipe 4, water pump 5, cooling water tank 6, circulating pump 10, and cooler 11 form a circulating cooling system, continuously removing heat from the mixing chamber 1.

[0044] The heat dissipation plates 12 on both sides of the mixing chamber 1 provide simultaneous auxiliary heat dissipation. The heat from the mixing chamber 1 is conducted to the heat dissipation plates 12, and due to their large surface area, the heat is quickly dissipated into the surrounding air, further reducing the temperature of the mixing chamber 1.

[0045] After a period of operation, if the coolant temperature becomes too high or the water level becomes too low, the controller located on one side of the cooling water tank 6 receives feedback signals from the cooling water tank 6 and other components, and controls the solenoid valve 8 in the outlet pipe 14 to open, discharging excess coolant. Then, it opens the solenoid valve 8 in the inlet pipe 13, allowing external water to flow into the cooling water tank 6 to replenish the coolant. Simultaneously, based on feedback signals from various components, the controller coordinates and regulates the working status of the mixing chamber 1, as well as the operation of the water pump 5, solenoid valve 8, circulating pump 10, and cooler 11, ensuring the stable operation of the entire cooling and mixing process.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
