Description

Technical Field

[0001] The invention relates to the technical field of corrugated pipe extrusion equipment, in particular to a high-temperature resistant liquid-cooled server FEP Teflon annular corrugated pipe extrusion equipment. Background Art

[0002] As data centers have higher requirements for energy efficiency and heat dissipation, liquid cooling technology has become one of the key technologies to improve server performance and reliability. FEP (fluorinated ethylene propylene copolymer) has become an ideal material for liquid cooling server pipes due to its excellent chemical resistance, electrical insulation, low friction coefficient and good thermal stability.

[0003] FEP material itself has high high temperature resistance. Therefore, when using FEP material to produce annular bellows for liquid cooling servers, the extrusion equipment needs to heat the raw material to a higher temperature, generally around 400°C.

[0004] When the existing FEP raw materials are put into the extrusion equipment, they will be accumulated in the discharge hopper connected to the screw conveyor in the extrusion equipment. Then, when the screw conveyor in the extrusion equipment is working, the raw materials will fall into the screw conveyor for transportation and heating and melting. However, due to the high melting point of the FEP raw materials, the temperature in the screw conveyor is also very high. The heat in the screw conveyor can easily enter the discharge hopper connected to it, causing the raw materials to melt and agglomerate before entering the screw conveyor, which can easily block the discharge port of the discharge hopper. Therefore, a high-temperature resistant liquid-cooled server FEP Teflon annular bellows extrusion equipment is proposed. Summary of the invention

DETAILED DESCRIPTION

[0026] 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 described embodiments 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 technical field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-8The present invention discloses a high temperature resistant liquid cooling server FEP Teflon annular corrugated pipe extrusion device, comprising an extruder body 1, a screw conveyor 2, a heater 3, a control cabinet 5 and a molding cooling machine 4, all of which are prior art. The heater 3 is installed outside the screw conveyor 2 for heating the screw conveyor 2. The heater 3 used in the present invention adopts three-stage heating, that is, the temperature of the initial stage after the screw conveyor 2 is fed is 280-300°C, the temperature of the middle stage is 300-340°C, and the discharge temperature is 340-380°C, so as to meet the requirement that the plastic fat of the FEP Teflon annular corrugated pipe raw material is completely melted and avoids degradation. At the same time, the temperature near the feed port of the screw conveyor 2 is the lowest, reducing the melting phenomenon caused to the raw material that has not entered. The molding cooling machine 4 is used to extrude the tubular outer wall extruded from the screw conveyor 2 into a corrugated shape and cool it down. The present invention adopts water cooling, and the control cabinet 5 is used to control the operation of all equipment. The overall automatic control system is adopted to automatically control the pressure, extrusion speed, heating temperature and cooling temperature of the FEP Teflon annular corrugated pipe during the extrusion process.

[0028] A partition tube 7 is installed on the feed port of the screw conveyor 2, and a discharge hopper 6 is installed on the upper end of the partition tube 7. The discharge hopper 6 is used to store FEP Teflon annular corrugated pipe raw materials. A cross bar 8 is installed on the inner wall of the upper end of the discharge hopper 6. A driving device 9 is installed on the cross bar 8. A threaded rod 10 is installed on the output end of the driving device 9. The output end of the threaded rod 10 extends into the screw conveyor 2. The inner wall of the partition tube 7 is provided with a first convex ring 11 and a second convex ring 12. The upper end surfaces of the first convex ring 11 and the second convex ring 12 are both inclined structures. The outer wall of the lower end of the threaded rod 10 is threadedly connected with a first bucket baffle plate 14 and a second bucket baffle plate 15 sliding in the second convex ring 12 The inner wall of the second convex ring 12 is provided with two limiting grooves 13, and the outer walls of the first bucket baffle plate 14 and the second bucket baffle plate 15 are fixedly connected with a limiting rod 16 which is slidably connected with the limiting grooves 13. In the initial state, the upper end of the first bucket baffle plate 14 is located in the first convex ring 11, thereby shielding the raw materials in the upper discharge hopper 6, and the second bucket baffle plate 15 is located above the second convex ring 12, so that there is a shielding between the screw conveyor 2 and the discharge hopper 6, and the heat in the screw conveyor 2 will not directly flow into the discharge hopper 6 to cause the raw materials to melt and agglomerate and block the discharge of materials. When it is necessary to transport raw materials into the screw conveyor 2, the driving device 9 is started to work. The driving device 9 drives the threaded rod 10 to rotate, and under the cooperation of the limiting rod 16 and the limiting groove 13, the threaded rod 10 drives the first bucket baffle plate 14 and the second bucket baffle plate 15 to descend. When the lowest point of the upper surface of the first bucket baffle plate 14 moves to the space between the first convex ring 11 and the second convex ring 12, the material in the discharge hopper 6 slides from the first bucket baffle plate 14 to the second bucket baffle plate 15, and as the first bucket baffle plate 14 and the second bucket baffle plate 15 move downward, the material moves downward accordingly. When the second bucket baffle plate 15 moves out of the second convex ring 12, the first bucket baffle plate 14 slides to the second convex ring 12, and continues to block the space between the screw conveyor 2 and the discharge hopper 6. At the same time, after the second convex ring 12 moves down, its side is not blocked by the second convex ring 12, and the raw materials on its surface fall into the screw conveyor 2 with gravity to realize loading. After loading is completed, the driving device 9 drives the threaded rod 10 to reverse, thereby making the first bucket baffle plate 14 and the second bucket baffle plate 15 move back for the next material receiving. During the entire movement process, one of the first bucket baffle plate 14 and the second bucket baffle plate 15 is always in the second convex ring 12, cutting off the direct flow of air between the screw conveyor 2 and the discharge hopper 6, thereby avoiding the heat in the screw conveyor 2 affecting the raw materials in the discharge hopper 6, causing the raw materials to melt and agglomerate and block the discharge, thereby improving practicality.

[0029] An eccentric column 18 located in the discharge hopper 6 is fixedly installed on the outer wall of the threaded rod 10, and the outer wall of the eccentric column 18 is rotatably connected to the eccentric guide block 17. When the threaded rod 10 rotates, the eccentric column 18 is driven to rotate, and the eccentric guide block 17 is driven to move through the eccentric column 18. The eccentric guide block 17 blocks the raw materials in the discharge hopper 6 to a certain extent, reduces the material discharge speed, and avoids the phenomenon of raw materials being blocked in the discharge hopper 6.

[0030] An inner toothed ring 19 is fixedly connected to the inner wall of the lower end of the discharge hopper 6, and a plurality of toothed blocks 20 meshing with the inner toothed ring 19 are fixedly connected to the outer wall of the eccentric guide block 17. When the threaded rod 10 drives the eccentric column 18 to rotate, the eccentric guide block 17 is driven to rotate by the eccentric column 18 through the meshing action of the toothed block 20 and the inner toothed ring 19. Due to its eccentric setting, the distance between its outer wall and the inner wall of the discharge hopper 6 is not equal during the rotation process. Then, through the rotation of the eccentric guide block 17, the raw materials in the unloading process can be squeezed and crushed, reducing the agglomeration in the raw materials, ensuring the melting effect of the raw materials entering the screw conveyor 2, and improving practicality.

[0031] The driving device 9 is specifically a fan, the output end of which extends to the outside and is fixedly connected to the upper end of the threaded rod 10. The fan can draw air in the forward direction and blow air in the reverse direction. A heat-resistant inflatable filler 25 sleeved on the outside of the threaded rod 10 is installed on the bottom surface of the first bucket baffle plate 14. The material of the heat-resistant inflatable filler 25 can be made of heat-resistant materials such as rubber and have the ability to expand and contract. A movable tube 24 communicating with the inside of the heat-resistant inflatable filler 25 is penetrated by the first bucket baffle plate 14, and a fixed tube 23 is sleeved on the outer wall of the movable tube 24. One end of the fixed tube 23 is penetrated to the outside of the partition tube 7 and is connected to the wind output end of the driving device 9. When the driving device 9 drives the threaded rod 10 to lower the first bucket baffle plate 14 and the second bucket baffle plate 15, the movable tube 24 slides with the fixed tube 23, and the driving device 9 generates a suction force to extract the gas in the heat-resistant inflatable filler 25 through the movable tube 24 and the fixed tube 23. The first and second bucket baffle plates 14 and 15 are compressed and then given way, so that the raw materials enter between the first bucket baffle plate 14 and the second bucket baffle plate 15. The second bucket baffle plate 15 moves to the outside of the second convex ring 12. After the raw materials above it all fall into the screw conveyor 2, the driving device 9 reverses at this time, and drives the first and second bucket baffle plates 14 and 15 to rise through the threaded rod 10. At the same time, the driving device 9 reverses the fan blades to generate a blowing force. The blown wind enters the heat-resistant inflatable filling member 25 through the fixed pipe 23 and the movable pipe 24, so that the heat-resistant inflatable filling member 25 expands and fills the space between the first bucket baffle plate 14 and the second bucket baffle plate 15. Because the second bucket baffle plate 15 moves to the bottom of the second convex ring 12, the heat of the screw conveyor 2 will enter the second convex ring 12 and be located between the first bucket baffle plate 14 and the second bucket baffle plate 15. The heat between the first bucket baffle plate 14 and the second bucket baffle plate 15 can be squeezed out by the expanded heat-resistant inflatable filling member 25, such as Figure 7As shown, after the first bucket baffle plate 14 and the second bucket baffle plate 15 rise, the heat entering the partition pipe 7 and affecting the raw materials is reduced, thereby further improving practicality.

[0032] There are two movable tubes 24 and two fixed tubes 23, and both movable tubes 24 are connected to the heat-resistant inflatable filling piece 25. One of the fixed tubes 23 is connected to the wind output end of the driving device 9, and the other fixed tube 23 is connected to the outside and is installed with a one-way valve (the common structure is not shown in the figure). When the gas is transported into the heat-resistant inflatable filling piece 25, the excess gas after the heat-resistant inflatable filling piece 25 expands can be discharged from the fixed tube 23, so as to avoid excessive expansion and damage of the heat-resistant inflatable filling piece 25 caused by excessive gas filling into the heat-resistant inflatable filling piece 25. At the same time, when the driving device 9 is evacuating air, the one-way valve at the end of the fixed tube 23 prohibits air from entering, ensuring that the gas in the heat-resistant inflatable filling piece 25 can be completely evacuated to reduce its volume.

[0033] A plurality of heat dissipation holes 21 are provided on the outer wall of the separator tube 7. The heat dissipation holes 21 are located on the outer wall of the separator tube 7 between the first convex ring 11 and the second convex ring 12. The heat dissipation holes 21 can improve the heat dissipation effect inside the separator tube 7 and further reduce the heat inside the separator tube 7. The heat dissipation holes 21 are of an inclined structure with their high ends facing upward, thereby avoiding the phenomenon of the heat dissipation holes 21 being blocked by raw materials.

[0034] An outer convex groove 22 is provided in the middle of the partition tube 7, and the inner bottom surface of the outer convex groove 22 is level with the upper end surface of the second convex ring 12. After the first bucket baffle plate 14 descends into the second convex ring 12, raw materials will fall on the first bucket baffle plate 14. When the first bucket baffle plate 14 rises, part of the raw materials can be pushed into the outer convex groove 22 to facilitate the return movement of the expanded heat-resistant inflatable filling member 25, thereby avoiding the phenomenon that too much raw material affects the return movement of the first bucket baffle plate 14.

[0035] The partition pipe 7 is connected to the screw conveyor 2 through a flange and bolts, and the discharge hopper 6 is installed with the screw conveyor 2 through a flange. The whole is convenient for disassembly and assembly, maintenance, and use.
