Description

Technical Field

[0001] This utility model relates to the technical field of kraft pipe production equipment, and in particular to a rapid shaping and cooling device for HDPE kraft pipes. Background Technology

[0002] HDPE Krah pipe, or high-density polyethylene spiral wound structured wall pipe, is a new type of environmentally friendly drainage pipe made primarily of high-density polyethylene (HDPE) using a hot-winding molding process. Due to its excellent properties such as light weight, high strength, corrosion resistance, aging resistance, and convenient construction, it is widely used in municipal engineering, sewage treatment, farmland irrigation, power and telecommunications, and other fields, undertaking important functions such as drainage, sewage discharge, and water transportation. In the production process of HDPE Krah pipe, the shaping and cooling stage is crucial, directly affecting the dimensional accuracy, surface quality, and physical properties of the pipe, playing a decisive role in ensuring product quality and production efficiency.

[0003] Currently, existing equipment uses a relatively simple cooling method with a fixed spray angle, making it difficult to achieve all-round, multi-angle cooling of the pipe. This results in uneven cooling of the pipe surface, which easily leads to quality defects such as deformation, dents, and cracks, seriously affecting product yield and enterprise economic benefits. Therefore, a rapid shaping and cooling equipment for HDPE Krah pipe is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rapid shaping and cooling device for HDPE kraft pipes. It aims to improve the existing technology by providing a relatively simple cooling method and a fixed angle of the spray device, which makes it difficult to achieve all-round and multi-angle cooling of the pipe, resulting in uneven cooling of the pipe surface and making it easy to cause quality defects such as deformation, dents, and cracks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid shaping and cooling device for HDPE kraft pipes, comprising a base plate, a cooling box fixedly connected to the top of the base plate, a fixed plate fixedly connected to the inner wall of the cooling box, a rotating ring rotatably connected inside the fixed plate, a toothed ring fixedly connected to the outer circumference of the rotating ring, multiple water spray pipes fixedly connected to the outer wall of the rotating ring, multiple nozzles fixedly connected to the outer wall of the water spray pipes, a driving assembly provided on the outer wall of the base plate, a return pipe I provided at the bottom of the base plate, and an adjustment assembly provided at the top of the return pipe I;

[0006] The drive assembly includes a housing, which is fixedly connected to the outer wall of the base plate. A rotating shaft is rotatably connected inside the housing. An impeller is fixedly connected to one end of the rotating shaft, and a gear is fixedly connected to the other end of the rotating shaft.

[0007] As a further description of the above technical solution:

[0008] The regulating assembly includes a housing, which is fixedly connected to the bottom of the outer wall of the first return pipe. A third return pipe is fixedly connected to the bottom of the housing, and a second return pipe is fixedly connected to the outer wall of the housing. A thermostat is fixedly connected inside the housing, and a connecting rod is fixedly connected to the outer wall of the thermostat. A baffle is fixedly connected to the side of the connecting rod away from the thermostat, and a spring is sleeved on the outer wall of the connecting rod.

[0009] As a further description of the above technical solution:

[0010] A water tank and a water pump are provided between the top of the base plate and the bottom of the cooling box. A water pumping pipe is provided between the water pump input end and the water tank. A water outlet pipe is fixedly connected to the water pump output end. The end of the water outlet pipe away from the water pump passes through the housing and is fixedly connected inside the fixed plate.

[0011] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the drive component moves under the action of water flow, and the gear drives the gear ring to rotate, which in turn drives the rotating ring to rotate. Multiple water spray pipes are evenly distributed around the rotating ring. As the rotating ring rotates, the nozzles atomize the water flow to cover the surface of the HDPE kraft pipe in all directions.

[0023] 2. In this utility model, the thermostat in the regulating component acts as the "intelligent brain" of the device, monitoring the cooling water temperature in real time and precisely controlling the baffle action according to a preset threshold. When the water temperature is low, the water flows back to the water tank quickly through the return pipe two, reducing unnecessary heat dissipation links, accelerating the water circulation speed, and improving cooling efficiency; when the water temperature is too high, the water is guided through the return pipe three, where it is efficiently cooled by the heat dissipation fins before flowing back.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a rapid shaping and cooling device for HDPE kraft pipes, comprising a base plate 1, which serves as the basic load-bearing component of the device, providing stable support for a cooling box 2 and other components. A cooling box 2 is fixedly connected to the top of the base plate 1. The cooling box 2 is used to accommodate HDPE kraft pipes for cooling and shaping, forming a relatively enclosed cooling space inside. A fixing plate 3 is fixedly connected to the inner wall of the cooling box 2, providing a rotational support base for a rotating ring 4. A rotating ring 4 is rotatably connected inside the fixing plate 3. The rotating ring 4 rotates within the fixing plate 3, and through a toothed ring 5 cooperating with a drive assembly, achieves rotational action, thereby driving a water spray pipe 6 to rotate. A toothed ring 5 is fixedly connected to the outer circumference of the rotating ring 4. Multiple water spray pipes 6 are fixedly connected to the outer wall of the rotating ring 4. The water spray pipes 6 can spray water to cool the HDPE Krah pipe from different angles during the rotation of the rotating ring 4, thereby improving the uniformity and efficiency of cooling. Multiple nozzles 7 are fixedly connected to the outer wall of the water spray pipes 6. The nozzles 7 disperse the water flow into fine water mist, increasing the contact area with the HDPE Krah pipe. A drive assembly is set on the outer wall of the base plate 1. The drive assembly is set on the outer wall of the base plate 1 to provide power for the rotation of the rotating ring 4. A return pipe 17 is set at the bottom of the base plate 1. An adjustment assembly is set at the top of the return pipe 17. The return pipe 17 is used to collect the cooled water flow. The adjustment assembly can process and control the return water flow, making the water circulation of the cooling system more reasonable and efficient.

[0033] Reference Figures 1-3 The drive assembly includes a housing 12, which is fixedly connected to the outer wall of the base plate 1. The housing 12 provides a mounting base for other components in the drive assembly, ensuring the stability of the drive assembly during operation. A rotating shaft 14 is rotatably connected inside the housing 12. The rotating shaft 14 is used to rotate to achieve power rotation. An impeller 13 is fixedly connected to one end of the rotating shaft 14. The impeller 13 is used to drive the rotating shaft 14 to rotate. A gear 15 is fixedly connected to the other end of the rotating shaft 14. The gear 15 is used to rotate and drive the gear ring 5 to rotate through meshing with the gear ring 5.

[0034] Reference Figure 5The regulating assembly includes a housing 16, which is fixedly connected to the bottom of the outer wall of the first return pipe 17. The housing 16 provides installation space and protection for other components within the regulating assembly. A third return pipe 19 is fixedly connected to the bottom of the housing 16, and a second return pipe 18 is fixedly connected to the outer wall of the housing 16. The second and third return pipes 18 and 19 are respectively connected to the outer wall and bottom of the housing 16 to divert the cooled water flow. A thermostat 20 is fixedly connected inside the housing 16, and a connecting rod 21 is fixedly connected to the outer wall of the thermostat 20. The side of the connecting rod 21 away from the thermostat 20 is fixedly connected to... A baffle 22 is connected, and a spring 23 is sleeved on the outer wall of the connecting rod 21. The thermostat 20 is installed inside the outer casing 16 and can monitor the temperature of the return water flow in real time. When the water flow temperature reaches the set value, the thermostat 20 drives the baffle 22 to move through the connecting rod 21, thereby changing the direction of the water flow. When the water flow temperature is low, the thermostat controls the baffle to make the water flow directly back to the water tank 8 through the return pipe 2 18, reducing the heat dissipation links. When the water flow temperature is high, the thermostat 20 controls the baffle 22 to make the water flow through the return pipe 3 19, dissipate heat through the heat dissipation fins 24, and then return to the water tank 8.

[0035] Reference Figure 1 A water tank 8 and a water pump 9 are installed between the top of the base plate 1 and the bottom of the cooling box 2. The water tank 8 is used to store cooling water and provide water for the entire cooling system. A water pump 10 is installed between the input end of the water pump 9 and the water tank 8. The output end of the water pump 9 is fixedly connected to the outlet pipe 11. The water pump 9 draws water from the water tank 8 through the water pump 10, and after being pressurized, it is delivered to the inside of the fixed plate 3 through the outlet pipe 11. Then, the HDPE corrugated pipe is sprayed with water for cooling through the spray pipe 6 and the nozzle 7. The end of the outlet pipe 11 away from the water pump 9 passes through the housing 12 and is fixedly connected to the inside of the fixed plate 3, so that the rotating ring 4 can be driven to rotate by the water flow during the water delivery process.

[0036] Reference Figure 2 The meshing between gear 15 and gear ring 5 can accurately transmit the power of the drive component to the rotating ring 4, ensuring the stable rotation of the rotating ring 4, which in turn drives the water spray pipe 6 and the nozzle 7 to cool the HDPE corrugated pipe evenly. A sealing ring is provided at the connection between the fixing plate 3 and gear ring 5 to prevent water from leaking from the connection during the cooling process and causing damage to other parts of the equipment.

[0037] Reference Figure 1 The end of the return pipe 18 away from the outer casing 16 is located inside the water tank 8. The return pipe 18 directly introduces the water flow that has been preliminarily treated by the regulating component and has a low temperature into the water tank 8, so as to realize the rapid recycling of water resources.

[0038] Reference Figure 1A heat dissipation fin 24 is fixedly connected to the top of the base plate 1. The end of the return pipe 3 19 away from the outer casing 16 passes through the heat dissipation fin 24 and is located inside the water tank 8. The heat dissipation fin 24 can increase the contact area with the air and improve the heat dissipation efficiency. When the regulating component determines that the water flow is at a high temperature, it flows through the heat dissipation fin 24 via the return pipe 3 19, and the heat is dissipated into the air through the heat dissipation fin 24, which lowers the water temperature before it flows back to the water tank 8.

[0039] Reference Figure 5 One end of the connecting rod 21 is fixedly connected to the outer wall of the thermostat 20, and the other end of the connecting rod 21 is fixedly connected to the baffle 22. The spring 23 is used to provide elastic force and to provide a restoring force to the baffle 22 when the thermostat 20 is not in operation, so that the baffle 22 is kept in the initial position, ensuring the stability and reliability of the adjustment component.

[0040] Reference Figure 4 The outer wall of the impeller 13 is rotatably connected to the inside of the housing 12, allowing the impeller 13 to rotate freely within the housing 12. When cooling water flows through the impeller 13, the impact force of the water flow drives the impeller 13 to rotate.

[0041] Working principle: After the equipment is started, the water pump 9 begins to work, drawing cooling water from the water tank 8 through the water pipe 10. After pressurization, the water is delivered to the outlet pipe 11. The water flowing out of the outlet pipe 11 enters the housing 12 and impacts the impeller 13. The impeller 13 begins to rotate under the impact force of the water flow. The impeller 13 is connected to the gear 15 through the rotating shaft 14, transmitting the rotational power to the gear 15. Since the gear 15 meshes with the gear ring 5, the rotation of the gear 15 drives the gear ring 5 to rotate, which in turn causes the rotating ring 4, which is fixedly connected to the gear ring 5, to rotate inside the fixed plate 3. When the rotating ring 4 rotates, it drives the multiple water spray pipes 6 fixed on its outer wall to rotate together, so that the nozzles 7 on the water spray pipes 6 can spray water to cool the HDPE corrugated pipe from different angles.

[0042] After cooling the HDPE corrugated pipe, the water flow is collected through the return pipe 17 at the bottom of the base plate 1. After entering the return pipe 17, the water flows into the housing 16 of the regulating component. The thermostat 20 inside the housing 16 monitors the water temperature in real time. When the water temperature is low and has not reached the set temperature of the thermostat 20, the thermostat 20 does not activate. Under the action of the spring 23, the baffle 22 remains in its initial position. At this time, the water flows directly back to the water tank 8 through the return pipe 18 to participate in the next cooling cycle. When the water temperature is high and reaches the set temperature of the thermostat 20, the thermostat 20 is activated. Through the connecting rod 21, it overcomes the elasticity of the spring 23, pushing the baffle 22 to move, changing the direction of the water flow, and causing the water to flow through the return pipe 19. The return pipe 19 passes through the heat dissipation fins 24 at the top of the base plate 1. As the water flows through the heat dissipation fins 24, heat is dissipated into the air, achieving cooling. The cooled water eventually flows back to water tank 8 and participates in the cooling cycle again.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
