[0002] A leaching filter press (also known as leaching pressure filter) is a device used for solid-liquid separation, mainly used in the process of extracting solutes or solute mixtures from solids. It usually consists of a filter tank, filter material, filter bottom, filter cloth, filter medium and filter press device;

[0003] At present, in order to clean the leaching filter press, a back-purge device is often used to backwash the leaching filter press. The use of primary wash water can effectively recover the lithium oxide in the wash water, so that the lithium oxide can be effectively recycled in the process system; secondly, the use of primary wash water for backwashing can effectively prevent pipeline blockage; thirdly, it can effectively reduce the water volume storage in the workshop.

[0004] However, the existing back-flushing device for the leaching filter press also has certain shortcomings. First, the pipe head and the tail end feed pipe used in the existing back-flushing device for the leaching filter press are mostly fixed by threads, which is obviously inconvenient for operators to use;

[0005] Secondly, the existing back-flushing devices of the leaching filter press mostly simply use the liquid inlet to fill the water tank with water.
