Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for processing polyethylene water pipelines. Background Technology

[0002] Polyethylene water pipes have good physical and chemical properties, corrosion resistance, high pressure resistance, and long service life, making them an important part of modern water supply and drainage systems. During the processing of existing polyethylene water pipes, cooling devices are required to cool them and solidify them.

[0003] The most common cooling method is to immerse the freshly extruded polyethylene pipe in a water tank filled with cooling water, using the heat dissipation property of water to rapidly reduce the temperature of the pipe, ensuring that it gradually cools and solidifies in the mold. However, existing polyethylene water pipes lack a pre-cooling structure during processing, and simply immersing them in water reduces the cooling efficiency of the polyethylene water pipes.

[0008] A first air outlet device is fixedly installed on the outer wall of the outer tube. A heat dissipation ring is provided on one side of the outer tube and penetrated by an outer cooling pipe. A plurality of first air outlet holes are provided on the inner wall of the heat dissipation ring, and the heat dissipation ring is connected to the air outlet end of the first air outlet device through a conduit.

The air outlet pipe is provided with a plurality of second air outlet holes, and the air outlet end of the second air outlet device is connected to the air outlet pipe.

[0010] To facilitate assembly of the heat dissipation ring, the present invention includes an improvement in that the heat dissipation ring has multiple support rods on its periphery, and the bottom end of each support rod has a fixing ring fixed to the outer wall of the outer cooling pipe.

[0011] Furthermore, an improvement of this utility model is that the fixing ring is fixed to the outer wall of the external cooling pipe by screws.

[0012] To ensure the heat dissipation effect of the internal cooling pipe, the improvement of this utility model is that a motor is fixedly installed in the inner ring of the internal cooling pipe, the output end of the motor is provided with a support rod connected to the second air outlet device, and multiple brushes are provided on the outer wall of the air outlet pipe to contact the second heat dissipation fins.

[0013] Furthermore, the improvements of this utility model include that the duct is a flexible hose and the air outlet pipe is made of metal.

[0014] Furthermore, an improvement of this utility model is that the motor is a servo motor.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a cooling device for processing polyethylene water pipelines, which has the following beneficial effects:

[0017] The first heat dissipation fins provide heat dissipation for the outer cooling pipe, and the second heat dissipation fins provide heat dissipation for the inner cooling pipe. This accelerates the heat exchange between the outer and inner cooling pipes on the polyethylene water pipe, thereby providing a pre-cooling effect for the polyethylene water pipe during transportation and improving the cooling efficiency of the polyethylene water pipe.

[0028] When this structure is in use, the extruded polyethylene water pipe will be transported between the outer pipe 1 and the inner pipe 2, and between the outer cooling pipe 3 and the inner cooling pipe 4. During this process, the first heat dissipation fin 5 can provide heat dissipation for the outer cooling pipe 3, and the second heat dissipation fin 14 can provide heat dissipation for the inner cooling pipe 4. This can accelerate the heat exchange between the outer cooling pipe 3 and the inner cooling pipe 4 on the polyethylene water pipe, thereby providing a pre-cooling effect for the polyethylene water pipe during transportation and improving the cooling efficiency of the polyethylene water pipe.
