[0002] A cooling water supply system is a water circulation device used to provide cooling for equipment and machinery. This device lowers the equipment temperature by supplying cooling water, ensuring stable operation at a suitable temperature. Therefore, cooling water supply systems are widely used in various industrial production processes, especially in equipment and machinery requiring precise temperature control.
[0003] The published patent document CN202911107U discloses a cooling water circulation system for an injection mold production line, including a work frame, a water tank, a small water pump, and a water distribution valve. A water tank and a small water pump are installed on the work frame, connected via pipelines. The small water pump is connected to the water distribution valve via a pipeline. One outlet of the water distribution valve is connected to the inlet of the mold temperature controller via a pipeline, and the other outlet is connected to the inlet of the unit via a pipeline. The water distribution valve is connected to the water tank via a pipeline. Because the water tank in the above device is in an open environment, the cooling water inside is easily contaminated with dust and other impurities. However, the device lacks a filter, allowing these dust and impurities to directly enter the equipment pipelines with the cooling water, causing blockages or wear. Utility Model Content

The position of the filter screen 17 is adjusted and placed inside the water inlet cylinder 4, so that the filter screen 17 can filter during the water supply process, filtering dust and other impurities in the cooling water to ensure the cleanliness of the cooling water and prevent dust and other impurities from entering the equipment pipeline with the cooling water and causing blockage. The position of the fixing ring 12 is adjusted by the elastic force of the spring 11, so that the fixing ring 12 slides and fits at the connection between the sealing cylinder 9 and the mounting groove 7, limiting and fixing the sealing cylinder 9 inside the mounting groove 7, and sealing the connection between the two to prevent water leakage. Cooling water is injected into the water tank 1 through the cooling water supply unit 3, and the cooling water in the water tank 1 is extracted through the cooling water output unit 2 and supplied to the equipment to be cooled.
