Description

Technical Field

[0001] The utility model relates to the technical field of temperature control, in particular to a temperature control device for the production of thermoplastic pipes. Background Technique

[0002] In the existing cooling systems of thermoplastic pipe preparation devices, the spraying method is mostly used. However, this cooling method often leads to insufficient use of the coolant due to the single contact area, reducing the cooling efficiency.

[0003] The patent with the application number CN202221121889.5 discloses a temperature control device for plastic pipe production. A cooling box is sleeved and installed outside the barrel of the extruder. Circular holes are evenly opened at the top of the cooling box, and fans are embedded in the circular holes. Cold air inlet pipes are symmetrically embedded at the top of both sides of the cooling box. Slide grooves are symmetrically opened on the inner wall of the cooling box, and arc-shaped baffles are slidably connected in the slide grooves. A drain pipe is embedded in the middle of the bottom end of the barrel of the extruder, and an exhaust pipe is embedded outside the drain pipe. A temperature sensor is installed outside one end of the barrel of the extruder. A controller is installed on the outside of the cooling box by screws. The air flow blown by the fan drives the input cold air to move. At the same time, the arc-shaped baffle restricts the moving track of the air flow, making it move along the outside of the barrel of the extruder. However, this device has the problem that it cannot cool the barrel of the extruder evenly, and the cold air entering the device cannot completely fill the device, unable to meet the required cooling effect.

[0022] The working process of this device is as follows: Before the device starts working, operate the touch screen 7 to start the device and ensure its working state. When the device starts working, cooling water enters the interior of the casing 1 through the water inlet pipe 3, so that the cooling water can be evenly sprayed above the extruder barrel 2 to conduct the first temperature control on the extruder barrel 2. When the incoming cooling water reaches the middle of the casing 1, the cooling water will enter the double-layer pipe 9. There is a first spiral device 12 in the inner layer 32 of the double-layer pipe. Above the first spiral device 12, there is a support frame 23. Above the support frame 23, there is a first rotating motor 13. The output shaft of the first rotating motor 13 passes through the top of the support frame 23 and is connected to the first spiral device 12. When the first rotating motor 13 starts, the output shaft of the first rotating motor 13 rotates, driving the first spiral device 12 to rotate. There are bosses on the edges of the spiral blades of the first spiral device 12. When the first spiral device 12 rotates, the cooling water entering the double-layer pipe 9 will be conveyed upward to the cooling tank 6 along with the rotation of the first spiral device 12. The bosses on the edges of the spiral blades can ensure that the cooling water is not overflowed during the conveying process. When the cooling water enters the cooling tank 6, cooling fans 11 are provided at the center points on the left and right sides and the rear side of the cooling tank 6. When the cooling fans 11 work, they will timely dissipate the heat in the cooling tank 6, thereby cooling the cooling water entering the cooling tank 6. A part of the cooled cooling water flows into the casing circulation pipe 4. The casing circulation pipe 4 is connected above the casing 1. The cooled cooling water enters the casing 1 through the casing circulation pipe 4 and is evenly sprayed above the extruder barrel 2, thereby conducting the second temperature control on the extruder barrel 2. Another part of the cooling water that has been cooled in the cooling tank 6 enters the circulation tank 5 through the second spiral device 14. The second rotating motor 15 is installed at the bottom of the cooling tank 6. The output shaft of the second rotating motor 15 passes through the bottom of the cooling tank 6. The screw in the second spiral device 14 is fixedly installed on the output shaft of the second rotating motor 15. When the second rotating motor 15 works, the second spiral device 14 rotates, thereby driving the cooling water to enter the circulation tank 5. The bosses on the edges of the spiral blades of the second spiral device 14 can ensure that the cooling water is not overflowed during the conveying process. Below the circular hole of the circulation tank 5, there is a spiral device housing 34, which can help the cooling water to be better conveyed into the circulation tank. When the cooling water fills the circulation tank 5, the excess cooling water in the tank enters the circulation pipe 29. The circulation pipe 29 is connected to the connection hole provided on the outer wall of the double-layer pipe 9. The cooling water enters the outer layer 31 of the double-layer pipe, enabling it to cool the cooling water being conveyed in the inner layer 32 of the double-layer pipe, greatly improving the cooling efficiency. The cooling water entering the outer layer 31 of the double-layer pipe will flow into the casing 1 again. The casing 1 is connected to the double-layer pipe 9. Sealing rings 8 are provided in the inner layer 32 and the outer layer 31 of the double-layer pipe at the connection. Check valves 33 are provided on both sides of the sealing ring 8. The check valves 33 can make the liquid flow unidirectionally.Even if the circulating cooling water in the outer layer 31 of the double-layer tube can flow into the inside of the casing 1, it is ensured that the cooling water inside the casing 1 will not enter the outer layer 31 of the double-layer tube, thus completing the circulation of the cooling water and better exerting the cooling effect of the device. Cooling fans 11 are provided on the left and right sides of the outer side of the top of the barrel support frame 27. Square card slots are provided on the left and right sides of the outer side of the top of the barrel support frame 27 to install the cooling fans 11. When they start working, they can dissipate heat from the cooling water in the casing 1, and then control the temperature of the extruder barrel 2 for the third time. A fan rotation motor 18 is provided on the heat dissipation base 19 of the cooling fan 11. The fan rotation motor 18 is connected to the fan blade 17. The fan blade 17 is installed on the rotation motor output shaft 20 of the fan rotation motor 18. A heat dissipation shell 16 is installed above the outer side of the heat dissipation base 19. A water leakage strip device is provided below the casing 1. When the device finishes working, by operating the touch screen 7, the third rotation motor 23 installed on the device base 21 starts working. A base rotating rod 24 is installed on the output shaft of the third rotation motor 23. A connecting shaft 30 is installed in the hole at the top of the base rotating rod 24. The connecting shaft 30 passes through the hole at the top of the movable block rotating rod 26, so that the movable block rotating rod 26 and the base rotating rod 24 are connected to each other. The movable block 22 is installed in the inner groove of the device base 21. A smooth rod 25 is provided above the movable block 22. The movable block rotating rod 26 is provided on the smooth rod 25. The tail of the movable block rotating rod 26 has a hole and is sleeved on the smooth rod 25. When the third rotation motor 23 starts working, the base rotating rod 24 rotates, and then the movable block rotating rod 26 rotates, so that the movable block 22 can move left and right in the inner groove of the device base 21. When the device finishes working, the movable block 22 is moved into the groove, and the water leakage strip device 10 is opened to drain the cooling water. After the drainage is completed, the movable block 22 is moved out of the groove, and the water leakage strip device 10 is closed to ensure the sealing of this water cooling device.
