Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil production, and particularly relates to an automatic cleaning device for an additive metering pump. Background Art

[0002] In the production process of electrolytic copper foil, the additive metering pump is one of the essential devices. However, the existing cleaning of the additive metering pump usually involves disassembling the pump and externally connecting an intelligent pulse cleaning machine for cleaning. This method can only be carried out after the production system of the electrolytic copper foil is shut down. The shutdown period of the production system of the electrolytic copper foil is about 2 - 3 months. Shutting down the production system for cleaning the additive metering pump will cause a large amount of economic losses to the production enterprise. However, if the additive metering pump is not cleaned in time, dirt is likely to grow in the additive metering pump, resulting in phenomena such as blockage of the additive pipeline and interruption of the additive flow. In severe cases, it will affect the production progress and the quality of the copper foil. Therefore, an automatic cleaning device for an additive metering pump is proposed to solve the above problems. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an automatic cleaning device for an additive metering pump.

[0005] An automatic cleaning device for an additive metering pump of the utility model includes an additive tank, an additive pipeline, a pump, an additive liquid supply pipeline, and a high-level tank. One end of the additive pipeline is communicated with the additive tank, and the other end is communicated with the feed end of the pump. One end of the additive liquid supply pipeline is communicated with the discharge end of the pump, and the other end is communicated with the high-level tank. It further includes a pure water inlet pipe. A first inlet valve is provided on the additive pipeline. One end of the pure water inlet pipe is communicated with the additive pipeline, and the communication position is between the first inlet valve and the pump.
