Description

Technical Field

[0001] This utility model belongs to the field of granulation technology, specifically a device for regulating the temperature uniformity of plastic granulation. Background Technology

[0002] In the plastic granulation process, the raw material is first extruded through a screw extruder, then the extruded strip is cooled, and finally sheared and granulated by a shearing machine. The existing cooling method is usually water cooling. However, existing water cooling devices are usually single-tank structures, so it is not convenient to adjust the cooling temperature in stages. For crystalline materials such as PE and PP, slow cooling (three-stage cooling of hot water, warm water and cold water) is required to reduce internal stress and avoid cracking. Conventional single-tank water cooling devices are not convenient for adjusting the temperature uniformity of crystalline materials such as PE and PP to achieve cooling. Therefore, this application proposes a plastic granulation temperature uniformity adjustment device. Utility Model Content

[0018] Depend on Figures 1 to 4 The present invention discloses a plastic granulation temperature uniformity adjustment device, comprising a support base 1, a support frame 2 fixedly mounted on the top of the support base 1, and a water-cooled pool 3, a water-cooled pool 4, and a water-cooled pool 5 sequentially mounted on the top of the support frame 2. A Z-shaped flat water pipe 6 is installed between the water-cooled pool 4 and the water-cooled pool 5, and a Z-shaped flat water pipe 7 is installed between the water-cooled pool 3 and the water-cooled pool 4. A filter assembly 8, a circulating pump 9, and a circulating water chiller 10 are sequentially mounted on the top of the support base 1. A U-shaped flat water pipe 11 is installed between the water-cooled pool 3 and the filter assembly 8. The filter assembly 8 is connected to the circulating water... A return pipe 12 is provided between the chiller 10 and the circulating pump 9 is connected to the return pipe 12. A return pipe 2 13 is provided between the circulating water chiller 10 and the water cooling pool 3 5. Temperature sensors 22 are fixedly installed on one side inside the water cooling pool 3, water cooling pool 2 4 and water cooling pool 3 5. Several heating rods 23 are fixedly installed inside the water cooling pool 3 and water cooling pool 2 4. A controller is provided on the front of the circulating water chiller 10. The installation height of the Z-shaped flat water pipe 2 7 is less than the installation height of the Z-shaped flat water pipe 1 6. The installation height of the U-shaped flat water pipe 11 is less than the installation height of the Z-shaped flat water pipe 2 7.

[0019] Before use, fill water cooling tank 3, water cooling tank 4, water cooling tank 5, and filter assembly 8 with water. Heating rod 23 heats the water in water cooling tank 3 and water cooling tank 4, making the water temperature in water cooling tank 3 higher than that in water cooling tank 4, and the water temperature in water cooling tank 4 higher than that in water cooling tank 5. The extruded raw material passes through water cooling tank 3, water cooling tank 4, and water cooling tank 5 in sequence, thus achieving slow cooling. During this process, circulation pump 9 and circulating water chiller are started. 10. To achieve water circulation and cool the water, preventing the water temperature from rising continuously during the cooling process and affecting the cooling effect, return pipe 12 and return pipe 23 return the cooled water to the interior of water cooling pool 3 5. The installation height of Z-shaped flat water pipe 2 7 is less than the installation height of Z-shaped flat water pipe 1 6, and the installation height of U-shaped flat water pipe 11 is less than the installation height of Z-shaped flat water pipe 2 7, so that the cooling water can automatically flow in water cooling pool 1 3, water cooling pool 2 4, and water cooling pool 3 5.

[0020] A drain pipe 14 is fixedly installed at the bottom of one side of the water-cooled pool 3. A valve 15 is installed on the drain pipe 14. Auxiliary support rollers 16 are rotatably installed at both ends of the top of the water-cooled pool 3, water-cooled pool 4, and water-cooled pool 5. Several auxiliary support rollers 2 17 are rotatably installed inside the water-cooled pool 3, water-cooled pool 4, and water-cooled pool 5. The installation height of the auxiliary support rollers 2 17 is less than the installation height of the auxiliary support rollers 16. Limit rods 18 are fixedly installed on both sides of the top of the water-cooled pool 3, water-cooled pool 4, and water-cooled pool 5.

[0022] The filter assembly 8 consists of a filter box 19, a drawer box 20, and filter cotton 21. The drawer box 20 is inserted and connected to the top of the front of the filter box 19. The bottom surface of the drawer box 20 has a mesh structure, and the filter cotton 21 is laid inside the drawer box 20.

[0023] The circulating water passes through the filter box 19 and is filtered by the filter cotton 21. The drawer box 20 has a pull-out design, which makes it easy to replace the filter cotton 21. The bottom of the drawer box 20 has a mesh structure, which allows the cooling water to fall to the bottom of the filter box 19.

[0024] In operation, the system is equipped with three water-cooling pools (one, two, and three), Z-shaped flat water pipes (one and two), a temperature sensor, and a heating rod. This allows for segmented cooling of the extruded plastic material, achieving slow cooling. The system also includes a filter assembly, a circulating pump, a circulating water chiller, U-shaped flat water pipes, and return pipes (one and two) to achieve water circulation and temperature control, thus enabling segmented and cyclical cooling. Auxiliary support rollers (one and two) support the extruded strip material, reducing friction. A limiting rod restricts the movement of the extruded strip material. Finally, a filter assembly consisting of a filter box, a drawer box, and filter cotton filters the circulating water, maintaining its cleanliness.
