Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and more specifically, to a polyglycerol ester cooling granulator. Background Art

[0002] Polyglycerol ester is an important chemical raw material, widely used in the production of chemical products such as plastics, rubber, and coatings. Cooling granulators can process polyglycerol ester into granules, which facilitates storage, transportation and subsequent processing, improves production efficiency and product quality, and meets the needs of large-scale production in the chemical industry.

[0003] The existing cooling system mainly uses air cooling. The air cooling section is equipped with multiple powerful fans arranged along the material extrusion direction to initially and rapidly cool the tubular material strips formed by the freshly extruded polyglycerol ester, so that the surface is initially solidified and prevents adhesion.

[0004] However, during the cooling process, temperature inconsistencies can easily occur between the inside and outside of the material and between different parts. Because the heat dissipation in the center of the tubular material strip is relatively slow, the air-cooled airflow is far from the center of the tubular material strip, while the sides are close to the contact surface of the cooling medium. The tubular material strip that is directly blown by the air-cooled airflow cools down quickly, resulting in uneven cooling of the formed tubular material strip. This can easily lead to cracks or misshapen particles when cutting them into granules, affecting the overall quality of the particles and their subsequent performance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a polyglycerol ester cooling granulator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A polyglycerol ester cooling granulator includes a support frame, with multiple electric telescopic rods fixedly installed at the bottom of the support frame, and a U-shaped frame fixedly installed at the top of the support frame, with a cooling mechanism installed inside the U-shaped frame;

[0008] The cooling mechanism includes a fixed plate fixedly mounted on one side of a U-shaped frame. A water pump is fixedly mounted on the top of the fixed plate. A delivery pipe is fixedly mounted on the input end of the water pump. A water inlet pipe is passed through one side of the delivery pipe. A collection box is passed through one end of the water inlet pipe. A connecting pipe is fixedly mounted on the output end of the water pump. A branch frame is passed through one end of the connecting pipe. Multiple atomizing nozzles are passed through the bottom of the branch frame. A water stop valve is fixedly mounted on one side of both the delivery pipe and the water inlet pipe. The top of the collection box is connected to the bottom of the support frame. Two mounting slots are opened inside the U-shaped frame. A fan is fixedly mounted inside each of the two mounting slots. Dust screens are fixedly mounted on both sides of the fan.

[0009] By adopting the above technical solution, the cooling mechanism integrates water cooling and air cooling. Water cooling is achieved through a water pump and atomizing nozzles, while a fan accelerates heat dissipation. This effectively improves the cooling and solidification efficiency of the tubular material strips formed by polyglycerol ester, ensuring the product molding quality. Moreover, it enables the recycling of cooling water, saving water resources and facilitating the stable operation of the device.

[0010] As a further description of the above technical solution: an auxiliary mechanism is provided on the top of the support frame. The auxiliary mechanism includes an auxiliary frame fixedly installed on the top of the support frame. The auxiliary frame is located on one side of the U-shaped frame. An air pump is fixedly installed on the top of the auxiliary frame. An air inlet pipe is fixedly installed at the output end of the air pump. One end of the air inlet pipe passes through the auxiliary frame and extends into the auxiliary frame. A branch pipe is provided through the other end of the air inlet pipe. A fixing groove is opened inside the auxiliary frame, and the branch pipe is located inside the fixing groove.

[0011] By adopting the above technical solution, additional air cooling is provided for the cooling and granulation of polyglycerol ester, enhancing the cooling effect, accelerating the cooling and solidification process of the tubular material strips formed by polyglycerol ester, improving the overall production efficiency, and ensuring that the air cooling effect can be applied to the material evenly and continuously, which helps to improve product quality and make the material cool more evenly and in a more stable state.

[0012] As a further description of the above technical solution: one end of the branch pipe is fixedly provided with an air distribution frame, and multiple top air outlet ducts are provided through the bottom of the air distribution frame; the other end of the branch pipe is provided with a side air outlet duct; the input end of the air pump is fixedly provided with an air inlet pipe; a stabilizing frame is provided through one side of the air inlet pipe; a filter screen is inserted into the inside of the stabilizing frame; a conveyor belt is provided on one side of the support frame; and an inclined plate is fixedly provided inside the collection box.

[0013] By adopting the above technical solution, air cooling becomes more uniform and comprehensive, accelerating the cooling and solidification of the tubular material strips formed by polyglycerol ester from multiple directions, improving cooling quality and efficiency, ensuring good product molding condition, and the filter screen in the stabilizing frame at the air inlet can filter air impurities, ensuring that the air participating in cooling is clean, avoiding contamination of the tubular material strips, and facilitating the production of high-quality polyglycerol ester products.

[0014] The technical effects and advantages of this utility model are:

[0015] By incorporating a cooling mechanism, compared to existing technologies, the atomized water mist generated by a water pump works synergistically with the air blown out by a fan to cool the tubular material strips formed from freshly extruded high-temperature soft polyglycerol ester. The combination of water cooling and air cooling greatly improves cooling efficiency. The water mist can cover a large area and evenly on the surface of the tubular material strips, fully absorbing the heat of the material strips and evaporating it away. Meanwhile, the fan accelerates airflow, which not only promotes the rapid discharge of hot air and timely replenishment of cold air, but also makes the water mist evaporate more quickly, allowing the surface of the tubular material strips to cool down rapidly and achieve preliminary cooling and solidification. This helps to improve the product molding quality and the convenience of subsequent processing. Moreover, the collection box collects the unevaporated water, which can be pumped back through the atomizing nozzles for recycling, reducing production costs and water waste, and also contributing to the long-term stable operation of the device.

[0016] By incorporating auxiliary mechanisms, the stabilizer frame with a filter screen at the air pump inlet effectively avoids this contamination risk compared to existing technologies, ensuring high-quality production of polyglycerol ester products. The air, pressurized by the air pump, passes through branch pipes, a uniform air distribution frame, and multiple top and side air ducts to cool the tubular polyglycerol ester strips from different directions. On one hand, the air blown downwards from the top air duct directly acts on the top of the tubular strips, while the air blown from the side air ducts covers the sides. This comprehensive air cooling ensures more uniform heat exchange throughout the tubular strips, preventing localized overheating or insufficient cooling. On the other hand, the blown air effectively dries excess moisture from the surface of the polyglycerol ester strips, further optimizing the material's condition and allowing it to better enter subsequent processes, thus improving product stability and quality.

[0023] The following will be combined with the 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.

[0024] The embodiments disclosed in this application are as follows: Figure 1-5 The polyglycerol ester cooling granulator shown includes a support frame 1, with multiple electric telescopic rods 2 fixedly installed at the bottom of the support frame 1, and a U-shaped frame 3 fixedly installed at the top of the support frame 1. A cooling mechanism is installed inside the U-shaped frame 3.

[0025] The cooling mechanism includes a fixed plate 4 fixedly installed on one side of the U-shaped frame 3, a water pump 5 fixedly installed on the top of the fixed plate 4, a delivery pipe 6 fixedly installed at the input end of the water pump 5, a water inlet pipe 7 passing through one side of the delivery pipe 6, a collection box 8 passing through one end of the water inlet pipe 7, a connecting pipe 9 fixedly installed at the output end of the water pump 5, a branch frame 10 passing through one end of the connecting pipe 9, and multiple atomizing nozzles 11 passing through the bottom of the branch frame 10. A water stop valve is fixedly installed on one side of both the delivery pipe 6 and the water inlet pipe 7. The top of the collection box 8 is connected to the bottom of the support frame 1. Two mounting slots 12 are opened inside the U-shaped frame 3. A fan 13 is fixedly installed inside both mounting slots 12. Dust screens 14 are fixedly installed on both sides of the fan 13.

[0026] Connect the external water source to the inlet pipe 7, open the stop valve on one side of the inlet pipe 7, and then start the water pump 5. The input end of the water pump 5 is through the inlet pipe 7. At this time, the stop valve on one side of the delivery pipe 6 is in the closed state, so that the external water source is delivered to the branch frame 10 through the connecting pipe 9 at its output end by the action of the water pump 5. After the water enters the branch frame 10, it will be sprayed out from these atomizing nozzles 11 to form a fine water mist, which is then evenly sprayed onto the surface of the tubular material strips formed by polyglycerol ester. The water mist sprayed by the atomizing nozzles 11 turns into water after absorbing heat. As steam dissipates into the air, some of the unevaporated water drips into the collection tank 8. The inclined plate 26 fixedly installed inside the collection tank 8 guides the water flow to the collection tank 8, opens the stop valve on one side of the delivery pipe 6, and closes the stop valve on the inlet pipe 7. This allows the water collected in the collection tank 8 to be delivered by the water pump 5 through the delivery pipe 6 to the inside of the connecting pipe 9, and then enters the branch frame 10 through the connecting pipe 9 and is sprayed out through multiple atomizing nozzles 11 for recycling, saving water resources and achieving stable, efficient and relatively environmentally friendly operation of the entire device.

[0027] Meanwhile, two mounting slots 12 are opened inside the U-shaped frame 3. The fan 13 fixedly installed inside the mounting slot 12 starts to work. The dust screen 14 fixedly installed on both sides of the fan 13 can prevent external dust and other impurities from entering the fan 13 and being blown into the working area of ​​the equipment, affecting the cooling effect and quality of polyglycerol ester. The air blown out by the fan 13 will work together with the water mist sprayed by the atomizing nozzle 11 to cool the tubular material strip formed by polyglycerol ester after being extruded from the extruder and entering the area of ​​the U-shaped frame 3. The tubular material strip formed by the extruded polyglycerol ester is hot and soft. When the water mist comes into contact with the tubular material strip, it will absorb heat and evaporate, taking away some of the heat. At the same time, the air blown out by the fan 13 accelerates the air flow speed, which promotes the heat dissipation more quickly, so that the surface of the tubular material strip can be cooled down quickly, initially achieving cooling and solidification, preventing the tubular material strips from sticking together, and is transported by the conveyor belt 25.

[0028] Reference Figure 2-3As shown, an auxiliary mechanism is provided on the top of the support frame 1. The auxiliary mechanism includes an auxiliary frame 15 fixedly installed on the top of the support frame 1. The auxiliary frame 15 is located on one side of the U-shaped frame 3. An air pump 16 is fixedly installed on the top of the auxiliary frame 15. An air inlet pipe 17 is fixedly installed at the output end of the air pump 16. One end of the air inlet pipe 17 passes through the auxiliary frame 15 and extends into the auxiliary frame 15. A branch pipe 18 is provided through the other end of the air inlet pipe 17. A fixing groove is opened inside the auxiliary frame 15. The branch pipe 18 is located inside the fixing groove. A portion of the air passing through the air pump 16 enters the branch pipe 18 through the air inlet pipe 17 at the output end. The branch pipe 18 is located inside the auxiliary frame 15. Within the fixed slot, air enters the air distribution frame 19. Multiple top-outlet air ducts 20 are provided through the bottom of the air distribution frame 19. Air is blown downwards from these top-outlet air ducts 20, which further cools the polyglycerol tubular material strip that is being cooled, enhancing the cooling effect and promoting better heat dissipation and cooling of the tubular material strip from different angles. At the same time, a side-outlet air duct 21 is provided through the other end of the branch pipe 18, and air is also blown out from the side-outlet air duct 21 to cool the sides of the tubular material strip, making the overall cooling of the tubular material strip more uniform and accelerating the cooling and solidification process of the tubular material strip. Secondly, it also effectively dries the excess moisture on the surface of the polyglycerol tubular material strip.

[0029] Reference Figure 4-5 As shown, a distribution frame 19 is fixedly installed at one end of the branch pipe 18, and multiple top-outlet air ducts 20 are installed through the bottom of the distribution frame 19. A side-outlet air duct 21 is installed through the other end of the branch pipe 18. An air inlet pipe 22 is fixedly installed at the input end of the air pump 16. A stabilizing frame 23 is installed through one side of the air inlet pipe 22. A filter screen 24 is inserted into the inside of the stabilizing frame 23. A conveyor belt 25 is installed on one side of the support frame 1. An inclined plate 26 is fixedly installed inside the collection box 8. Then the air pump 16 is started, and outside air enters the air pump 16 through the air inlet pipe 22. A stabilizing frame 23 is installed through one side. A filter 24 inserted inside the stabilizing frame 23 filters the incoming air, intercepting dust and impurities to ensure that the air entering the air pump 16 and the air participating in the cooling process are clean, thus avoiding contamination of the polyglycerol ester product. The tubular material strip formed by the cooled and solidified polyglycerol ester falls onto the conveyor belt 25 installed on one side of the support frame 1. The conveyor belt 25 rotates at a uniform speed driven by an external motor, and the tubular material strip formed by the polyglycerol ester is cut into granules by an external cutting machine, thereby forming polyglycerol ester material granules.

[0030] Working principle of this utility model:

[0031] This invention relates to a polyglycerol ester cooling granulator. During operation, the polyglycerol ester material is extruded into tubular strips through an extruder die. Being in a high-temperature, relatively soft state, it requires immediate cooling to solidify. First, an external water source is connected to the inlet pipe 7, and the stop valve on one side of the inlet pipe 7 is opened. Then, the water pump 5 is started. The input end of the water pump 5 is connected to the inlet pipe 7. At this time, the stop valve on one side of the delivery pipe 6 is closed, allowing the external water source to be pumped through the output pipe 9 to the branch frame 10. After entering the branch frame 10, the water is sprayed from the atomizing nozzles 11, forming a fine water mist that is then evenly sprayed. The water is sprayed onto the surface of the tubular material strips formed by polyglycerol ester. The water mist sprayed by the atomizing nozzle 11 absorbs heat and turns into water vapor, which is then released into the air. Some of the unevaporated water drips into the collection box 8. The inclined plate 26 fixedly installed inside the collection box 8 can guide the water flow to the collection box 8, and open the water stop valve on one side of the conveying pipe 6 and close the water stop valve on the inlet pipe 7. Thus, the water collected in the collection box 8 is delivered by the output of the water pump 5, conveyed through the conveying pipe 6 to the inside of the connecting pipe 9, and then enters the branch frame 10 through the connecting pipe 9 and is sprayed out through multiple atomizing nozzles 11 for recycling, saving water resources, and achieving stable, efficient and relatively environmentally friendly operation of the entire device.

[0032] Meanwhile, two mounting slots 12 are opened inside the U-shaped frame 3. The fan 13 fixedly installed inside the mounting slot 12 starts to work. The dust screen 14 fixedly installed on both sides of the fan 13 can prevent external dust and other impurities from entering the fan 13 and being blown into the working area of ​​the equipment, affecting the cooling effect and quality of polyglycerol ester. The air blown out by the fan 13 will work together with the water mist sprayed by the atomizing nozzle 11 to cool the tubular material strip formed by polyglycerol ester after being extruded from the extruder and entering the area of ​​the U-shaped frame 3. At the same time, the water mist will absorb heat and evaporate after contacting the tubular material strip, taking away some heat. Meanwhile, the air blown out by the fan 13 accelerates the air flow speed, which promotes the heat dissipation more quickly, so that the surface of the tubular material strip can be cooled down quickly, initially achieving cooling and solidification, preventing the tubular material strips from sticking together, and is transported by the conveyor belt 25.

[0033] Next, the air pump 16 is started, and outside air enters the air pump 16 through the air inlet pipe 22. A stabilizing frame 23 is installed through one side of the air inlet pipe 22. The filter screen 24 installed inside the stabilizing frame 23 will filter the incoming air, intercept dust and impurities, and ensure that the air entering the air pump 16 and the air participating in the cooling process are clean, so as to avoid contamination of the polyglycerol ester product.

[0034] The air pump 16 passes through the air inlet pipe 17 at the output end and enters the branch pipe 18. The branch pipe 18 is set in the fixed groove opened inside the auxiliary frame 15. Then the air enters the air distribution frame 19. The bottom of the air distribution frame 19 is provided with multiple top air outlet ducts 20. The air will blow downward from these top air outlet ducts 20, which will further cool the tubular material strip formed by the polyglycerol ester that is cooling, enhance the cooling effect, and promote better heat dissipation and cooling of the tubular material strip from different angles. At the same time, the other end of the branch pipe 18 is provided with a side air outlet duct 21. The air will also blow out from the side air outlet duct 21 to cool the sides of the tubular material strip, making the overall cooling of the tubular material strip more uniform, accelerating the cooling and solidification process of the tubular material strip, and also effectively drying the excess moisture on the surface of the tubular material strip.

[0035] The tubular material strips formed by the cooled and solidified polyglycerol ester will fall onto the conveyor belt 25 set on one side of the support frame 1. The conveyor belt 25 will rotate at a constant speed driven by an external motor, and the tubular material strips formed by the polyglycerol ester will be cut into granules by an external cutting machine, thereby forming polyglycerol ester material granules.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
