Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE hot melt pipe production technology, and in particular to a circulating cooling device for PE hot melt pipe production. Background Technology
[0002] In modern industrial production, PE hot melt pipes are widely used in various fluid transmission systems due to their excellent physical properties and chemical stability. However, during the production process of PE hot melt pipes, the pipes in the high-temperature molten state need to be cooled rapidly to solidify and form. This process places extremely high demands on the performance of the cooling device. At present, although a circulating cooling device for PE hot melt pipe production on the market meets the production needs to a certain extent, it still has some shortcomings in terms of structural design and cooling efficiency.
[0003] Existing circulating cooling devices mainly use traditional cooling methods, such as natural cooling or simple water cooling. These methods have obvious defects in terms of cooling speed and uniformity, which can easily lead to uneven internal stress and inconsistent surface hardness in PE hot melt pipes during the cooling process, affecting the overall quality and performance of the pipes. Secondly, when circulating water sprays onto PE pipes, the water will carry away the heat from the surface of the PE pipes, but some water will remain on the surface of the PE pipes, causing corrosion. At the same time, since the water is recycled, the water temperature will gradually rise as cooling progresses, resulting in a decrease in the cooling effect of the water on the PE pipes. Utility Model Content
[0004] This utility model proposes a circulating cooling device for the production of PE hot melt pipes, which solves the problems of insufficient cooling efficiency, residual moisture on the surface of PE pipes, and reduced cooling effect of existing circulating cooling devices for the production of PE hot melt pipes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A circulating cooling device for PE hot melt pipe production includes a base plate, a waste storage box inside the base plate, a cooling box on top of the waste storage box, a through hole inside the cooling box, a conveyor located below the through hole inside the cooling box, limit frames on both sides of the top of the conveyor, a cooling mechanism outside the limit frames, a baffle in the middle of the cooling box, a high-pressure water pipe inside the cooling box on one side of the baffle, multiple atomizing nozzles at the bottom of the high-pressure water pipe, a cooling water tank above the high-pressure water pipe, and an air-cooling mechanism on the other side of the baffle.
[0007] Preferably, the bottom of the base plate is provided with multiple sets of shock absorbers, and the bottom of the shock absorbers is provided with a support top, and the top of the waste storage box is provided with a filter screen.
[0008] Preferably, mounting brackets are provided on both sides of the exterior of the cooling box below the through holes, and transmission rollers are provided inside the mounting brackets.
[0009] Preferably, the cooling mechanism includes heat sinks, cooling pipes, a circulating water pump, and a circulating pipe. Multiple sets of heat sinks are provided inside the limiting frame, and multiple sets of threaded cooling pipes are provided on the side of the heat sinks and the outside of the limiting frame. A circulating water pump is provided inside the cooling water tank at one end, and the circulating water pump is connected to the cooling pipes through the circulating pipes to form a cooling structure.
[0010] Preferably, a high-pressure water pump is installed inside the cooling water tank at the other end, and the high-pressure water pump is connected to the high-pressure water pipe through a connecting pipe, and a water inlet is provided on the top of the cooling water tank.
[0011] Preferably, the air-cooling mechanism includes an installation port, a blower fan, a protective net, heat dissipation holes, and a protective cover. The other end of the cooling box has installation ports on both sides, a blower fan is installed inside the installation port, and a protective net is installed outside the blower fan.
[0012] Preferably, a protective cover is provided above the baffle on the side of the cooling water tank, and the protective cover is provided with multiple sets of heat dissipation holes.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This circulating cooling device for PE hot melt pipe production features multiple atomizing nozzles at the bottom of the high-pressure water pipe. A high-pressure water pump is connected to the high-pressure water pipe via a connecting pipe. High-pressure atomization technology is employed to improve the fineness and uniformity of the water mist, ensuring even coverage of the pipe surface and enhancing the cooling effect. Furthermore, multiple sets of threaded cooling pipes are installed on the sides of the heat sink and the outside of the limiting frame, extending the length and increasing the number of cooling pipes to ensure sufficient time for heat exchange between the pipe and the cooling medium during the cooling process. Simultaneously, multiple heat sinks are installed inside the limiting frame, which helps improve heat conduction efficiency. In addition, the optimized cooling pipe layout avoids cooling blind spots, ensuring uniform cooling of all parts of the pipe and improving cooling efficiency.
[0015] 2. The other end of the baffle is equipped with a wind-cooling mechanism. After water cooling, the fan is turned on to remove the residual moisture and heat on the pipe surface through forced convection. This allows the heat to be discharged through multiple sets of heat dissipation holes inside the protective cover, directly expelling the heat to the outside and preventing heat accumulation. In addition, the forced convection air can also provide an additional heat dissipation channel for the cooling pipe, further reducing its operating temperature. The cooling effect can be further improved by the cooling water tank, effectively solving the problem of residual moisture on the pipe surface. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1
[0024] Reference Figures 1-5 This utility model provides a technical solution: a circulating cooling device for PE hot melt pipe production, including a base plate 1, a waste storage box 2 inside the base plate 1, a cooling box 3 on top of the waste storage box 2, a through hole 4 inside the cooling box 3, a conveyor 5 below the through hole 4 inside the cooling box 3, limit frames 6 on both sides of the top of the conveyor 5, a cooling mechanism outside the limit frames 6, a baffle 7 in the middle of the cooling box 3, a high-pressure water pipe 8 on the side of one end of the baffle 7 inside the cooling box 3, multiple sets of atomizing nozzles 9 at the bottom of the high-pressure water pipe 8, a cooling water tank 10 above the high-pressure water pipe 8, and an air-cooling mechanism on the side of the other end of the baffle 7.
[0025] Reference Figure 3 , Figure 4 , Figure 5The cooling tank 3 has mounting brackets 14 on both sides below the through holes 4, and the mounting brackets 14 have transmission rollers 15 inside. The cooling mechanism includes heat sinks 16, cooling pipes 17, circulating water pumps 18, and circulating pipes 19. The limiting frame 6 has multiple sets of heat sinks 16 inside. The sides of the heat sinks 16 and the outside of the limiting frame 6 have multiple sets of threaded cooling pipes 17. The cooling water tank 10 at one end has a circulating water pump 18 inside. The circulating water pump 18 is connected to the cooling pipes 17 through the circulating pipes 19 to form a cooling structure. The cooling water tank 10 at the other end has a high-pressure water pump 20 inside. The high-pressure water pump 20 is connected to the high-pressure water pipe 8 through the connecting pipe 21. The top of the cooling water tank 10 has a water inlet 28 for easy addition of cooling water.
[0026] In specific implementation, a circulating cooling device for PE hot-melt pipe production involves the following steps: First, the conveyor 5 is started, and the PE hot-melt pipe to be cooled is placed outside the drive roller 15. The pipe is then conveyed by the conveyor 5 through the through-hole 4 into the cooling box 3. After entering the cooling box 3, the high-pressure water pump 20 is started. The high-pressure water pump 20 delivers cooling water to the high-pressure water pipe 8 through the connecting pipe 21. Multiple atomizing nozzles 9 at the bottom of the high-pressure water pipe 8 then atomize and cool the surface of the PE hot-melt pipe. High-pressure atomization technology is used to improve the fineness and uniformity of the water mist, ensuring that the water mist evenly covers the pipe surface. To enhance the cooling effect, the circulating water pump 18 is then started. The circulating water pump 18 draws out the cooling water from the cooling water tank 10 and circulates it inside the threaded cooling pipe 17. After absorbing the heat from the surface of the PE hot melt pipe, the temperature of the cooling pipe 17 gradually rises, and then it flows back to the cooling water tank 10. In the cooling water tank 10, the high-temperature cooling water undergoes a series of cooling processes. After the temperature drops to the preset range, it is drawn out by the circulating water pump 18 again for recycling. This process is repeated to form a complete cooling cycle. Through the above operations, the cooling efficiency is improved, cooling blind spots are avoided, and all parts of the pipeline are uniformly cooled.
[0027] Example 2
[0028] Reference Figure 1 , Figure 2This embodiment is an optimization based on embodiment one. Multiple sets of shock absorbers 12 are provided at the bottom of the base plate 1, and a support top 13 is provided at the bottom of the shock absorber 12. The shock absorber 12 is used to reduce the vibration and effectively reduce the operating noise and reduce the impact of vibration on the equipment and the environment. A filter screen 27 is provided at the top of the waste storage box 2. The air-cooling mechanism includes an installation port 22, a blower 23, a protective net 24, heat dissipation holes 25, and a protective cover 26. The other end of the cooling box 3 has installation ports 22 on both sides inside. A blower 23 is provided inside the installation port 22, and a protective net 24 is provided outside the blower 23. A protective cover 26 is provided above the baffle 7 on the side of the cooling water tank 10, and multiple sets of heat dissipation holes 25 are provided inside the protective cover 26.
[0029] In a specific implementation, a circulating cooling device for PE hot-melt pipe production, when the circulating cooling device further cools, firstly, the PE hot-melt pipe is conveyed by the conveyor 5 into the other side of the baffle 7. Then, the blower 23 is started, and the residual moisture and heat on the pipe surface are removed by forced convection, thereby realizing the discharge of heat through multiple sets of heat dissipation holes 25 inside the protective cover 26. At the same time, the forced convection air can also provide an additional heat dissipation channel for the cooling pipe 17, further reducing the working temperature of the cooling water inside the cooling pipe 17, which helps to further improve the cooling effect. In this way, the problem of residual moisture on the pipe surface is effectively solved through the above operation, and the cooling efficiency is further improved.
