Description

Electrolyte filtering and filter aid coating device for manufacturing raw foil

Technical Field

The utility model belongs to the technical field of the copper foil production facility, concretely relates to electrolyte filter aid coating device is made to raw paper tinsel.

Background

The filtering tank purifies the electrolyte by using a physical adsorption principle. The electrolyte discharged from the dirty liquid tank contains impurity particles and is a liquid heterogeneous mixture. Under the action of fluid driving force, the electrolyte flows to the other side of the medium through the fine pore channels of the filter medium, and impurity particles in the electrolyte are intercepted by the medium, so that the separation of the fluid and the impurities is realized. The filter tank can obtain purer electrolyte when working normally, and can stabilize the liquid level of the clean liquid tank. When the internal pressure of the filter tank rises to 0.25MPa, the pressure cannot be reduced by adjusting the valve, and the liquid level of the liquid purifying tank begins to drop and is lower than the specified liquid level. This situation indicates that the filter cake in the filter tank is too tight and the electrolyte is subject to a large resistance to passage, thus requiring the filter aid to be reapplied to restore the function of the large filter tank. When the liquid level of the clean liquid tank drops or burrs appear in the whole train, the filter tank may need to be cleaned and the filter material is coated repeatedly. When thunder and power failure occur in rainy days, the activated carbon and the diatomite adsorbed on the filter screen collapse, and the filter material needs to be cleaned and coated again; the coating of the filter material in the filter tank is therefore a time-consuming and labor-intensive and high-quality process.
