Description

Technical Field

[0001] This utility model relates to the field of horizontal filter press technology, and in particular to a horizontal filter press with a cleaning device for ternary lithium battery materials. Background Technology

[0002] Ternary lithium battery materials can store and release more electrical energy, thus providing a longer driving range, especially in electric vehicles. Furthermore, ternary lithium battery materials also exhibit superior performance in low-temperature environments. The preparation of ternary lithium battery materials requires a horizontal filter press. A pressing plate compresses the two-by-two filter plates and diaphragm plates towards the thrust plate end. After reaching the predetermined pressing pressure, a pressure holding state is entered. The material enters the filter chamber formed between the filter plates through a feed pump, forming a filter cake layer on the filter cloth surface. The filtrate passes through the filter cloth and is discharged from the water channels on the filter plates. After pressing, compressed air or high-pressure water is introduced into the diaphragm plate to inflate the diaphragm and squeeze the filter cake, removing a large amount of water. After squeezing, washing liquid can be pumped in according to process requirements. The washing liquid passes through the cake layer and filter cloth to wash the filter cake. After washing, the filter cake is pressed again. Finally, the filter plates are pulled apart by a pull plate trolley, and the filter cake is unloaded by falling under its own gravity. However, traditional horizontal filter presses have the following disadvantages: a large amount of filter cake impurities adhere to the surface of the filter plates on traditional horizontal filter presses, and the cleaning workload of the horizontal filter press is large after each preparation.
