Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, specifically a circulating-cooled underwater pelletizer. Background Technology

[0002] A rubber and plastic pelletizer is a device specifically designed to cut rubber and plastic materials into small pellets. This type of machine is widely used in the production, recycling, and reprocessing of rubber and plastics, and is typically used to process waste rubber, recycled plastics, and manufacture raw material pellets.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN210496286U) discloses a circulating-cooling underwater pelletizer, comprising a working water tank and a processing tank. A cooling water pipe connects the working water tank and the processing tank, and a second pressure pump is installed on the cooling water pipe. A fixed pipe is provided on the working water tank, with one end of the fixed pipe fixedly connected to the outer wall of the working water tank. A fixing ring is fixedly connected to the end of the fixed pipe away from the working water tank, and the fixing ring is coaxially connected to the end of the fixed pipe. A connecting ring is fixedly connected around the outer wall of the cooling water pipe. The end of the cooling water pipe near the connecting ring is inserted into the fixing ring and the fixed pipe, and one end of the connecting ring abuts against one end of the fixing ring. A fixing bolt passes through the connecting ring and the fixing ring, and a fixing nut is threaded to the end of the fixing bolt. This circulating-cooling underwater pelletizer has the advantages of high material cooling efficiency and water saving.

[0004] Although the aforementioned patent has the advantages of high material cooling efficiency and water saving through the setting of cooling water pipes, during the circulating cooling process, the water pipes will continuously circulate. However, during the cooling flow, solid particles and impurities in the water may accumulate in the pump and pipes, leading to a decrease in pump performance, blockage or damage, thereby affecting the cooling performance. Without a filtration device, impurities in the device will increase the fluid resistance, affecting the stability and uniformity of the water flow, and may cause some equipment to overheat, affecting the pelletizing effect of rubber and plastic production.

[0005] Therefore, this invention provides a circulating cooling underwater pelletizer to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a circulating-cooled underwater pelletizer, such as... Figures 1-5 As shown, the underwater pelletizer with circulating cooling includes a water tank 1, an extruder 2 is fixedly connected inside the water tank 1, a water outlet is opened at the bottom of the water tank 1, a circulation mechanism is fixedly connected inside the water outlet, and a filter mechanism is fixedly connected to one end of the circulation mechanism.

[0029] The filtration mechanism includes a connecting pipe 3, one end of which is fixedly connected to one end of the circulation mechanism, and the other end of which is fixedly connected to a connecting cover A 4. One end of the connecting cover A 4 is threadedly connected to a connecting cover B 6 via a fixing bolt 5. A connecting cylinder 7 is fixedly connected inside the connecting cover B 6, and filter plates 8 are threadedly connected to both ends inside the connecting cylinder 7. One end of the connecting cover B 6 is fixedly connected to a water outlet pipe A 9, and a nut 10 is threadedly connected to the outer surface of the fixing bolt 5. During circulating cooling, the filter plates 8 can effectively remove solid particles, impurities, and sediments from the water, keeping the circulating water clean and preventing contaminants from damaging the equipment. When the filtered water passes through the heat exchanger, the temperature change is more uniform, which helps to improve the stability of the system.

[0030] The circulation mechanism includes a B-outlet pipe 11, one end of which is fixedly connected to the inside of the outlet hole. A flow pipe 12 is fixedly connected to the outer surface of the B-outlet pipe 11, and a circulation pump 13 is fixedly connected to one end of the flow pipe 12. The outer surface of the circulation pump 13 is fixedly connected to one side of the water tank 1. The heat generated during the pelletizing process will affect the life of the cutting tool and the cutting quality. Circulation cooling can effectively remove this heat, keep the temperature of the cutting area within an appropriate range, prevent overheating, and achieve the effect of water resource recycling, thereby saving water resources.

[0031] A support column 14 is fixedly connected to the bottom of the water tank 1. A connecting plate 15 is fixedly connected to one side of the support column 14. A drive motor 16 is fixedly connected to the back of the connecting plate 15. A fan 17 is splinedly connected to the output end of the drive motor 16. When the drive motor 16 is started, the drive motor 16 drives the fan 17 to rotate. The fan 17 blows air onto the flow pipe 12 to achieve the effect of convection cooling.

[0032] A baffle plate 18 is fixedly connected to the other side of the support column 14, and an anti-slip pad is fixedly connected to the bottom of the support column 14. When the fan 17 blows the air onto the flow pipe 12, the baffle plate 18 can block the rebound and circulate the air to cool the flow pipe 12.

[0033] The inner wall of the water tank 1 has a groove, and a water cooling pipe 19 is fixedly connected inside the groove. The water cooling pipe 19 can cool the water inside the water tank 1 to achieve the effect of cooling down and maintain the uniform temperature of the water inside the water tank 1.

[0034] Both sides of the water tank 1 are fixedly connected with buckles 20, and the outer surface of the buckles 20 is attached with a block 21. The buckles 20 and the block 21 can be used to fix the water tank 1 and the cover 22, which serves as a connection. The cover 22 serves as a dustproof cover to prevent impurities from entering the water tank 1.

[0035] One end of the locking block 21 is fixedly connected to a cover 22, and a handle 23 is fixedly connected to the upper surface of the cover 22. When it is necessary to check the internal condition of the water tank 1, the handle 23 is pulled to open the cover 22.

[0036] Specifically, when using extruder 2 to granulate rubber and plastic products, water is placed in water tank 1, and the water cooling pipe 19 in water tank 1 is activated. The water cooling pipe 19 cools the water in water tank 1, thus cooling extruder 2 and preventing continuous heating during pelletizing, which could lead to poor processing quality. Drive motor 16 is then activated, driving fan 17 to rotate. Fan 17 blows air onto flow pipe 12, achieving convective cooling. Water in water tank 1 flows from the outlet hole into outlet pipe 11 and then into flow pipe 12. As the water flows slowly within flow pipe 12, fan 17 cools it. Then, the circulation pump 13 is started. The circulation pump 13 draws water from the flow pipe 12 and flows the water out from the connecting pipe 3. If there are impurities in the water while it is flowing, the filter plate 8 is used to filter the impurities to keep the water clean. When the filtered water passes through the heat exchanger, the temperature change is more uniform, which helps to improve the stability of the system. When it is necessary to remove the impurities, the nut 10 and the fixing bolt 5 are loosened, the A connecting cover 4 and the B connecting cover 6 are separated, and the connecting cylinder 7 is taken out to remove the impurities for easy cleaning. Then, the filtered water flows from the A outlet pipe 9 into the water tank 1 to cool the extruder 2, achieving the effect of water circulation cooling.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
