Closing a valve II, opening a valve on a slag guide pipe, enabling battery materials uniformly stirred in a stirring tank to enter a tank body through a feeding pipe, discharging the battery materials to a liquid outlet pipe through a connecting pipe after the battery materials are filtered by a filtering device fixed on a mounting seat, supplying the battery materials to a coating machine through the liquid outlet pipe, blocking large granular substances and impurities outside the filtering device in the tank body, enabling the large granular impurities to enter a slag collecting tank after sedimentation, confirming whether a large amount of large granular substances and impurities are attached to a filtering barrel on the filtering device after a period of time, closing a valve I on the corresponding connecting pipe when the corresponding filtering device needs to be cleaned or replaced, rotating the lower filtering device through a handle, replacing a new filtering device, cleaning the replaced filtering device, and adjusting the amount of filtered battery slurry entering the liquid outlet pipe by opening a corresponding number of valves I, the coating machine which meets different requirements is used.

Preferably, handles are fixed on the upper end faces of the filter barrels. The filtering device is more convenient to replace through the handle.

Preferably, a plurality of limiting plates which are circumferentially and uniformly fixed outside the mounting seat are fixed on the periphery of the mounting seat. When changing filter equipment, through the more convenient location with filter equipment of limiting plate.

Preferably, a permanent magnet is fixed in the filter vat. The permanent magnet can effectively remove metal particles in the battery slurry.

Compared with the prior art, the utility model has the advantages that:

1. supply with for the coating machine after filtering battery thick liquid through this device and use, can have and avoid large granule impurity to flow to the coating machine.

2. When needing to wash or change the filter equipment who corresponds, close valve I on the connecting pipe that corresponds, through filter equipment under the handle rotation, change new filter equipment, the filter equipment that will change washs, and the replacement is very convenient to can directly take off filter equipment and wash, need not to shut down moreover and just can directly change filter equipment, can not influence the production efficiency of battery.

3. The amount of battery thick liquid entering drain pipe after can adjusting the filtration through opening the valve I that corresponds quantity, the coating machine that satisfies different demands uses, and filtration efficiency is high.
