Description

Technical Field

[0001] The utility model relates to the technical field of composite pipe production, in particular to a high-efficiency cooling device for continuous composite pipe production. Background Art

[0002] Composite pipes are based on a composite structure of metal and thermoplastics, lined with non-metallic materials such as polypropylene, polyethylene or externally welded cross-linked polyethylene, and have the advantages of both metal and non-metallic pipes. Composite pipes usually need to go through multiple steps such as extrusion, cooling, and shaping during the production process. During the extrusion process, the composite pipe will be in a high-temperature molten state. If it is not cooled at this time, the pipe will easily produce excessive internal stress due to the high temperature, resulting in a rough surface or uneven wall thickness of the formed pipe. The manufactured product is also prone to deformation during storage. Therefore, a high-efficiency cooling device for continuous production of composite pipes is required.

[0003] According to the search, the Chinese patent document, announcement number: CN210617259U, discloses a cooling device for composite pipe production. By setting a slider, a slide, a frame, a wiper, etc., it is only necessary to adjust the relative distance between the two limiting wheels and the corresponding caliber of the wiper to achieve cooling of composite pipes of different diameters. It is simple to operate, easy to use, and has a wide range of applications. However, in actual use, since the temperature of the pipe is high after extrusion and the temperature of the cooling water is low, if the pipe is directly in contact with cold water after extrusion, excessive internal stress may be generated, resulting in a rough surface or uneven wall thickness of the formed pipe, and the manufactured product is also prone to deformation during storage; in addition, since the device is only provided with one set of limiting wheels, when the winding device pulls the pipe to make it straight, only a small surface will be immersed in the cooling water, thereby reducing the overall cooling efficiency and continuous productivity of the device. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a high-efficiency cooling device for continuous production of composite pipes, which has the advantages of easy operation, gradual cooling, improved product quality and production efficiency, and solves the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a high-efficiency cooling device for continuous production of composite pipes, comprising a base plate, a baffle, a lower pulley seat, an air cooling box and a water cooling box are fixedly installed on the top surface of the base plate, a hydraulic cylinder is fixedly installed on the top surface of the baffle, an upper pulley seat is fixedly installed on the output shaft of the hydraulic cylinder, a fan is fixedly installed on the inner top surface of the air cooling box, a wiper is fixedly installed inside the water cooling box, a water leakage hole is opened through the top surface of the base plate, a funnel is fixedly installed on the bottom surface of the base plate, a collecting bucket is arranged directly below the funnel, a first water pipe is fixedly installed on the outer side surface of the collecting bucket, a water pump is fixedly connected to the left end of the first water pipe, a second water pipe is fixedly installed on the left side surface of the water pump, a radiator is fixedly connected to the left end of the second water pipe, a third water pipe is fixedly installed on the rear side surface of the radiator, a water spray pipe is fixedly connected to one end of the third water pipe away from the radiator, and a nozzle is fixedly installed on the outer side surface of the water spray pipe.

[0008] Preferably, the baffle, the lower pulley seat, the hydraulic cylinder and the upper pulley seat are all provided in plurality.

[0009] Through the above technical solution, the composite pipe is slidably installed inside the multiple lower pulley seats in turn, and then the multiple hydraulic cylinders are started, which can drive the multiple upper pulley seats to move downward, thereby effectively fixing and limiting the position of the composite pipe. At the same time, the device can also be adjusted according to the sizes of different composite pipe diameters, thereby improving the overall stability and applicability of the device.

[0010] Preferably, the number of the fans is plural.

[0011] Through the above technical scheme, after the composite tube is extruded and formed, it will first pass through the air cooling box. Starting multiple fans can effectively perform preliminary cooling on it. While effectively cooling it down, it also prevents it from cooling too fast and causing some adverse effects, thereby improving the overall practicality of the device.

[0012] Preferably, there are a plurality of nozzles, and the water spray pipe and the plurality of nozzles are installed inside the water cooling box.

[0013] Through the above technical solution, when the composite pipe reaches the inside of the water cooling box, the water pump is started, and the water pump can transport the coolant in the collection barrel to the inside of the radiator. After the coolant is dissipated and cooled by the radiator, it can be sprayed out from the inside of multiple nozzles through the third water pipe and the water spray pipe. After that, the coolant contacts the surface of the composite pipe to effectively cool it in all directions, thereby improving the overall cooling efficiency of the device.

[0014] Preferably, there are a plurality of water leakage holes, and the funnel is installed directly below the plurality of water leakage holes.

[0015] Through the above technical solution, after the coolant is sprayed out from the nozzle and cools the composite pipe, the coolant can flow out to the inside of the funnel through multiple leakage holes, and then the coolant can be recovered to the inside of the collection bucket through the funnel. While efficiently completing the cooling work, it also effectively recycles water resources, thereby improving the overall practicality of the device.

[0016] Preferably, there are multiple wiper blades.

[0017] Through the above technical solution, when the composite pipe is cooled by coolant spraying, some water droplets will remain on the outer side. As the winding device pulls the composite pipe through the scraper, multiple scrapers can effectively scrape off the water droplets on the outer side to ensure its normal performance, thereby improving the overall practicality of the device.

[0018] Compared with the prior art, the utility model provides a high-efficiency cooling device for continuous production of composite pipes, which has the following beneficial effects:

At the same time, the device can also be adjusted according to the diameters of different composite pipes, thereby improving the overall stability and applicability of the device. At the same time, some water droplets will remain on the outer side of the composite pipe after being sprayed with coolant for cooling. As the winding device pulls the composite pipe to pass through the wiper, the plurality of wipers can effectively scrape off the water droplets on its outer side to ensure its normal performance, thereby improving the overall practicality of the device.
