Technical Field
[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for PE pipe production. Background Art
[0002] PE pipe refers to the pipe made of PE resin as the main raw material. It is widely used in urban water and electricity pipe networks for its excellent impact resistance, crack resistance, aging resistance and corrosion resistance. The production process of PE pipe is mainly extrusion molding. The pipe body extruded by hot melt needs to be cooled by water spray to make it fixed.
[0003] When the existing PE pipe cooling device is used to cool the PE pipe, a spraying method is generally used for cooling. The cooled water contains harmful substances. If the cooled water is recycled, the harmful substances contained in the water will evaporate into the air, causing harm to the health of the workers. Generally, a filtering device is used to filter the harmful substances in the water. After a period of filtration, dust and impurities will accumulate on the filter net, causing the filter cartridge to be blocked, thereby affecting the filtration effect. Therefore, the filter cartridge needs to be frequently removed for cleaning. Therefore, a cooling device for PE pipe production is proposed to solve the above-mentioned problems.
