Description
Technical Field
[0001] This utility model relates to the field of power pipe production technology, specifically a rapid cooling device for MPP power pipe production. Background Technology
[0002] MPP power pipes are also called MPP power cable protection pipes and MPP cable protection pipes. MPP power pipes are divided into open-cut and trenchless types. MPP trenchless power pipes are also called MPP jacking pipes or drag pipes. MPP power pipes use modified polypropylene as the main raw material. They are pipes used in special locations such as roads, railways, buildings, and riverbeds to lay pipelines and cables without the need for extensive dredging, excavation, or road surface damage.
[0003] In existing cooling devices, MPP power pipes are usually placed statically in a cooling tank or moved linearly to a cooling pool via a conveyor belt for cooling. Because the contact area between the top and bottom of the pipe and the cooling water is different, thermal stress concentration is easily caused, which can lead to pipe bending or uneven wall thickness, thus affecting the cooling effect.
[0004] Therefore, those skilled in the art have provided a rapid cooling device for the production of MPP power pipes to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide a rapid cooling device for the production of MPP power pipes, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rapid cooling device for MPP power pipe production includes a main body. A support platform is fixedly connected to one side of the main body. A conveying mechanism is mounted on the top of the support platform. The conveying mechanism includes a servo motor, which is fixedly connected to the top of the support platform. A reducer is fixedly connected to the output end of the servo motor. A first gear is fixedly connected to the output end of the reducer. A chain is meshed with the outside of the first gear. A second gear is meshed with one side of the chain. A rotating rod is passed through the middle of the second gear. A rotating roller is sleeved on the outside of the rotating rod. A heat-resistant layer is provided on the outside of the rotating roller. A transparent protective cover is fixedly connected to the outside of the servo motor. A bracket is bolted to one side of the main body, and a water tank is installed on the top of the bracket. An output pipe is fixedly connected to one side of the water tank, and multiple atomizing nozzles are fixedly connected to the outside of the output pipe. A servo motor drives the rotating roller to rotate through a reducer and gear chain drive, so that the pipe is uniformly heated 360° during the cooling process, avoiding local overheating or deformation caused by static cooling. The multiple atomizing nozzles are evenly distributed along the pipe axis. The micron-sized water droplets sprayed out quickly vaporize and absorb heat after contacting the high-temperature pipe surface. The phase change process carries away a large amount of heat, pre-cooling the pipe in advance, avoiding direct contact between the cooling water and the pipe surface, which could cause sudden cooling cracks in the pipe, thereby improving the cooling efficiency.
[0008] As a further embodiment of this utility model: a circulating pump is installed inside the water storage tank, and a connecting pipe is fixedly connected to one side of the water storage tank. The connecting pipe has multiple limiting holes, each with a rubber ring fitted inside. An adjusting connector is inserted into each of the multiple limiting holes, and a nozzle is fixedly connected to one side of the adjusting connector. A control valve is installed on the outside of the connecting pipe. The multiple limiting holes, in conjunction with the adjusting connector, allow the nozzle to be inserted into different limiting holes, enabling multi-angle installation. This allows the nozzle to flexibly adjust the spray direction and coverage area according to the diameter, shape, and cooling requirements of the MPP power pipe, avoiding localized overheating, improving cooling uniformity and product quality. At the same time, the operator can adjust the spray water volume in real time through the control valve to achieve precise cooling of the pipe.
[0009] As a further improvement of this utility model: guide plates are fixedly connected to both sides of the bottom of the main body of the device, and the guide plates are inclined. A water collection cavity is provided at the bottom of the main body of the device. A drain pipe is inserted into one side of the water collection cavity, and one end of the drain pipe is fixedly connected to one side of the water storage tank. Water level monitoring strips are provided on one side of both the water storage tank and the water collection cavity. Wastewater generated during the cooling process can flow to the water collection cavity for collection under the action of the inclined guide plates, and after internal filtration, it is discharged to the water storage tank for reuse through the drain pipe. During the cooling process, the operator can monitor the water level inside the water storage tank and the water collection cavity in real time through the water level monitoring strips.
[0010] As a further improvement of this utility model: the inner wall of the water collection cavity is provided with a slot, a filter plate is engaged inside the slot, and a buckle is provided on one side of the filter plate. The filter plate is quickly engaged with the slot through the buckle. During maintenance, the filter plate can be removed by pressing the buckle with one hand, which greatly improves the convenience of operation.
[0011] As a further embodiment of this utility model: a mounting frame is fixedly connected to one side of the main body of the device, an axial flow fan is fixedly connected inside the mounting frame, an exhaust pipe is fixedly connected to the top of the main body of the device, and a heat exchanger is sleeved on the outside of the exhaust pipe. The axial flow fan directly blows the surface of the MPP power pipe with forced airflow, which can improve the evaporation rate of the atomized cooling water droplets and avoid deformation caused by local overheating.
[0012] As a further improvement of this utility model: a control switch is provided on one side of the main body of the device, a process indicator is provided on one side of the control switch, and a warning sign is provided on one side of the process indicator. The operator can start the device through the external control switch and the process indicator, and the warning sign can play a certain early warning role to prevent people from approaching the high-speed rotating gears out of curiosity, thereby improving the safety of use.
[0013] As a further improvement of this utility model: a shock-absorbing support is fixedly connected to the bottom of the main body of the device, and an anti-corrosion coating is provided inside the main body of the device. The shock-absorbing support reduces the shear stress of vibration on the coating and avoids the coating from cracking due to fatigue, while the anti-corrosion coating protects the metal substrate and reduces structural fatigue caused by vibration. The combination of the two can greatly improve the stability of the device in use.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The servo motor drives the rotating roller to rotate through the reducer and gear chain transmission, so that the pipe is uniformly heated 360° during the cooling process. This avoids local overheating or deformation caused by static cooling. In addition, multiple atomizing nozzles are evenly distributed along the pipe axis. The sprayed micron-sized water droplets quickly vaporize and absorb heat after contacting the high-temperature pipe surface. The phase change process carries away a large amount of heat, pre-cooling the pipe in advance and avoiding direct contact between the cooling water and the pipe surface, which could cause sudden cooling cracks. This improves the cooling efficiency.
[0016] 2. Multiple limiting holes, combined with adjusting connectors, allow the nozzle to be inserted into different limiting holes, enabling multi-angle installation. This allows the nozzle to flexibly adjust the spray direction and coverage area according to the diameter, shape, and cooling requirements of the MPP power pipe, avoiding localized overheating, improving cooling uniformity and product quality. At the same time, operators can adjust the spray water volume in real time through the control valve to achieve precise cooling of the pipe. Attached Figure Description

[0023] 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.
[0024] Example 1
[0025] Reference Figures 1-5This embodiment provides a rapid cooling device for MPP power pipe production, including a device body 1. A support platform 2 is fixedly connected to one side of the device body 1. A conveying mechanism 3 is provided on the top of the support platform 2. The conveying mechanism 3 includes a servo motor 301, which is fixedly connected to the top of the support platform 2. A reducer 302 is fixedly connected to the output end of the servo motor 301. A first gear 303 is fixedly connected to the output end of the reducer 302. A chain 304 is meshed with the outside of the first gear 303. A second gear 305 is meshed with one side of the chain 304. A rotating rod 306 is passed through the middle of the second gear 305. A rotating roller 307 is sleeved on the outside of the rotating rod 306. A heat-resistant layer 308 is provided on the outside of the rotating roller 307. A transparent protective cover 309 is fixedly connected to the external of the motor 301. A bracket 4 is bolted to one side of the main body 1. A water tank 5 is installed on the top of the bracket 4. An output pipe 6 is fixedly connected to one side of the water tank 5. Multiple atomizing nozzles 7 are fixedly connected to the outside of the output pipe 6. A circulation pump 8 is installed inside the water tank 5. A connecting pipe 9 is fixedly connected to one side of the water tank 5. The connecting pipe 9 has multiple limiting holes 10. Rubber rings 11 are fitted inside each of the multiple limiting holes 10. Adjusting connectors 12 are inserted into each of the multiple limiting holes 10. A nozzle 13 is fixedly connected to one side of the adjusting connector 12. A control valve 14 is installed on the outside of the connecting pipe 9. Guide plates 15 are fixedly connected to both sides of the bottom of the main body 1. The guide plates 15 are inclined. The device is inclined, and a water collection chamber 16 is provided at the bottom of the main body 1. A drain pipe 17 is inserted into one side of the water collection chamber 16, and one end of the drain pipe 17 is fixedly connected to one side of the water storage tank 5. Water level monitoring strips 18 are provided on one side of both the water storage tank 5 and the water collection chamber 16. A slot 19 is provided on the inner wall of the water collection chamber 16, and a filter plate 20 is engaged inside the slot 19. A buckle 21 is provided on one side of the filter plate 20. The high-temperature MPP power pipe to be cooled is placed on the surface of the rotating roller 307. Then, the conveying mechanism 3 is started by the external controller, and the servo motor 301 is started. The servo motor 301 converts the high-speed rotation into low-speed, high-torque output through the reducer 302, driving the first gear 303 to rotate. The first gear 303 meshes with the chain 304, driving the chain 304. Horizontal movement is achieved by chain 304 further driving the second gear 305 to rotate. The second gear 305 drives the rotating roller 307 to rotate via rotating rod 306. The heat-resistant layer 308 on the outside of the rotating roller 307 directly contacts the MPP power pipe, driving the pipe to rotate at a uniform speed through friction. Simultaneously, the circulating pump 8 is activated, allowing cooling water from the water tank 5 to be delivered to the atomizing nozzle 7 through the output pipe 6. The atomizing nozzle 7 refines water droplets into tiny particles, which are evenly sprayed onto the surface of the rotating MPP power pipe, pre-cooling the high-temperature pipe. At the same time, the adjusting connector 12 is inserted into the limiting hole 10 of the connecting pipe 9, and the rubber ring 11 ensures a seal. The flow rate and pressure of the nozzle 13 are adjusted by the control valve 14 to achieve directional cooling. The nozzle 13 can provide enhanced cooling for the MPP power pipe.To improve cooling efficiency, wastewater generated during the cooling process flows through an inclined guide plate 15 into a water collection chamber 16 at the bottom of the main body 1. Filter plates 20 within the water collection chamber 16 are fixed in slots 19 by clips 21, filtering impurities from the wastewater. The filtered wastewater then flows back to the water storage tank 5 through a drain pipe 17, achieving cooling water recycling. During the cooling process, the water level monitoring strips 18 on the sides of the water storage tank 5 and the water collection chamber 16 display the water level in real time. If the water level falls below the threshold, cooling water needs to be added to prevent the circulating pump 8 from running dry. Operators can adjust the flow rate of the output pipe 6 and the connecting pipe 9 via the control valve 14 to ensure the efficiency of the spray cooling.
[0026] Example 2
[0027] Reference Figures 1-5 This embodiment is based on the previous embodiment, but differs in that: a mounting frame 22 is fixedly connected to one side of the main body 1, an axial flow fan 23 is fixedly connected inside the mounting frame 22, an exhaust pipe 24 is fixedly connected to the top of the main body 1, a heat exchanger 25 is sleeved on the outside of the exhaust pipe 24, a control switch 26 is provided on one side of the main body 1, a process indicator 27 is provided on one side of the control switch 26, a warning indicator 28 is provided on one side of the process indicator 27, a shock-absorbing support 29 is fixedly connected to the bottom of the main body 1, and an anti-corrosion coating 30 is provided inside the main body 1. The operator follows the process... When the indicator 27 starts the control switch 26, the servo motor 301 drives the rotating roller 307 to rotate, and the circulating pump 8 and axial flow fan 23 start synchronously. During the cooling process, the airflow generated by the axial flow fan 23 directly acts on the surface of the rotating MPP power pipe, accelerating the evaporation of cooling water and carrying away residual water droplets on the surface of the pipe to prevent water stains. When the high-temperature exhaust gas inside the main body 1 passes through the heat exchanger 25, it exchanges heat with the external cooling air to reduce the exhaust temperature. At the same time, the bottom of the shock-absorbing support 29 is made of shock-absorbing rubber material to absorb the impact force of vibration sources such as the axial flow fan 23 and the circulating pump 8, reduce equipment resonance, and extend service life.
