Technical Field

[0001] The utility model relates to the technical field of lithium carbonate production, in particular to a filter press device for lithium carbonate production. Background Art

[0002] The main raw material for lithium carbonate production is salt lake brine. Lithium carbonate is purified and separated from high-magnesium, low-lithium old brine. Lithium carbonate is an inorganic compound in the form of colorless monoclinic crystals or white powder. It can be used to make ceramics, medicines, catalysts, etc. It is a commonly used raw material for lithium-ion batteries. The production of lithium carbonate requires a semi-finished product solid-liquid separation process, usually using a filter press.

[0003] After searching the publication (announcement) number: CN217312193U, a filter press device for lithium carbonate production is disclosed, including a base, a filter press body is fixedly installed on the top of the base, a door panel is movably connected to the front of the filter press body, a limit box is movably connected to one side of the filter press body, a bolt is movably connected to the top of the limit box, and a fixed plate is movably connected to the inner wall of the limit box. The filter press device for lithium carbonate production is provided with a fixed plate, which is inserted into the filter press body, the limit box is sleeved on the fixed plate, two bolts are provided, which pass through the limit box and are inserted into the card slot in the fixed plate, so that the fixed plate is fixed in the filter press body, and a filter screen is provided to perform the next step of filter pressing on the lithium carbonate material. The filter screen blocks impurities in the lithium carbonate material, effectively improving the quality of lithium carbonate filter pressing, thereby facilitating the installation or replacement of the filter screen and improving the working efficiency of lithium carbonate filter pressing.

[0004] Although the above scheme is convenient for installing or replacing the filter screen and improving the working efficiency of lithium carbonate filter pressing, it is not convenient for cleaning the filter screen. More and more impurities are accumulated on the filter screen, and the quality of lithium carbonate liquid filtered out of the lithium carbonate material is poor, and the working efficiency of the filter pressing device is reduced. For this reason, we propose a filter pressing device for lithium carbonate production. Utility Model Content
