[0002] A cooling tower is a device that lowers the temperature of water through direct or indirect contact between air and water. During the injection molding process, the cooling tower is responsible for cooling the hot water generated by the injection molding machine and then circulating it to the injection molding machine to maintain the normal operating temperature of the mold and the injection molding machine, ensuring that the injection molded parts can be successfully molded and achieve the expected quality.

[0003] The existing hot water may contain impurities, particulate matter, or sediment. If these substances are not filtered and enter the cooling tower directly, they may clog the packing, pipes, or water pumps, leading to a decrease in equipment performance or even damage.
