Description

Technical Field

[0001] The utility model relates to the technical field of cooling water filtration, in particular to a cooling water filtration device for a lead powder machine. Background Art

[0002] Lead powder machines are mainly used in battery production to produce lead powder required for grids. Lead powder production requires temperature control. When the temperature is high, the drum needs to be cooled by cooling water. The cooling water needs to be recycled to reduce resource waste. The cooling water cycle needs to be filtered accordingly to reduce the impact of impurities.

[0003] The utility model with the announcement number CN221287091U discloses a cooling water filter device, including a first filter cartridge and a second filter cartridge. Fixing mechanisms are fixed on both sides of the first filter cartridge. A filter element is installed inside the first filter cartridge. A cover plate is installed on the top of the first filter cartridge. Plugs are fixed to the four corners of the bottom of the cover plate.

[0004] The above technical solution solves the problem that the structure of flange connection is relatively complicated and requires matching. A slight error may cause leakage and vibration in the pipeline system, and multiple disassembly and assembly may also cause the connection to be not tight enough. However, when filtering cooling water, it is not convenient to increase the path of filtration, and after long-term filtration, the inside of the filter structure is not convenient to clean, and the overall replacement cannot be reduced, resulting in waste of resources. When cleaning the inside of the filter cartridge, the sealing cover is opened, and the cooling water in the pipeline is easy to leak out, polluting the surrounding environment. Utility Model Content
