Description

Technical Field

[0001] The utility model relates to the field of cooling and cooling in pipe production, in particular to a cooling and cooling device used in the production of polyethylene pipes. Background Art

[0002] Polyethylene is a highly crystalline, non-polar thermoplastic resin. The appearance of the original polyethylene is milky white, and it is translucent to a certain extent in the thin cross-section. Polyethylene has excellent resistance to most domestic and industrial chemicals. Polyethylene pipe is also called high-density polyethylene. Polyethylene is a highly crystalline, non-polar thermoplastic resin. The appearance of the original polyethylene is milky white, and it is translucent to a certain extent in the thin cross-section. Polyethylene has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals will cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. Polyethylene has good electrical properties, especially the high dielectric strength of the insulation, which makes it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance, which is the case at room temperature or even at low temperatures of -40F. The application range of polyethylene pipes ranges from small-section yellow pipes for natural gas to thick-walled black pipes with a diameter of 48in for industrial and urban pipelines to large-diameter hollow-wall pipes used as rainwater drain pipes and other sewer pipelines made of concrete, and its usage rate is growing rapidly.

[0003] Due to the thermoplasticity of polyethylene, the temperature required for polyethylene pipes during production is relatively high, and the temperature of polyethylene pipes after processing is also relatively high. Therefore, the pipes need to be cooled to increase the forming rate of the pipes. The large amount of cooling water used will easily cause waste, and the cooling water needs to be recycled to avoid waste. At present, there is a lack of cooling water collection and recycling equipment during cooling. At the same time, after water cooling, the pipes need to be dried, otherwise in the subsequent packaging process, the water will soak the packaging box, causing damage to the packaging box, packaging failure and other problems. The current cooling equipment does not have the function of drying the pipes, and an additional drying process is required, which makes the workflow complicated. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a cooling device for polyethylene pipe production, which is characterized by comprising a spray structure, a ventilation structure, and a water collection circulation structure. The ventilation structure is installed above the water collection circulation structure, and the spray structure is installed above the water collection circulation structure.

[0005] The spray mechanism is composed of a water inlet pipe, a control valve, a water storage tank, a water outlet pipe, and a nozzle. The control valve is installed on the water inlet pipe, the water inlet pipe is installed above the water storage tank, the water outlet pipe is installed below the water storage tank, and several nozzles are installed in parallel on the water outlet pipe.

[0006] The water collection circulation structure is composed of a liquid collecting box, a water leakage hole, a water outlet pipe, a filter, a sewage drainage pipe, a water return pipe, and a lifting pump. The liquid collecting box cover is provided with five rows of water leakage holes. The water outlet pipe is installed under the liquid collecting box. A filter is installed at one end of the water outlet pipe. A sewage drainage pipe is installed on one side of the filter. The other end of the filter is connected to the water return pipe. A lifting pump is installed on one side of the water return pipe. One end of the water return pipe is connected to the water storage tank.

[0007] The ventilation structure consists of a fan, a baffle A, and a baffle B. The baffle A is installed at the top left of the liquid collecting tank, and the baffle B is installed at the top right of the liquid collecting tank. Several fans are installed inside the baffles A and B, respectively. Power supplies are set inside the baffles A and B and are connected to the fans.

[0008] Beneficial effects of the utility model:

[0009] The utility model discloses a cooling device for the production of polyethylene pipes. A nozzle is provided to water-cool the polyethylene pipes after processing. The loading platform for placing the pipes is set as a hollow collecting box. The upper surface of the collecting box for placing the pipes is set as a curved surface. The pipes will not roll and fall after being placed. Five rows of water leakage holes are provided on the curved surface. The cooling water sprayed on the pipes can be collected into the collecting box. A filter is provided to filter and discharge impurities in the cooling water collected in the collecting box. The filtered cooling water can be returned to the water storage tank through a circulation system to continue cooling the pipes, thereby saving water resources. At the same time, the fan provided can air-dry the cooled pipes to avoid the residual water from the water cooling from wetting the packaging box, causing the packaging box to be damaged and the packaging to fail.
