Description

Technical Field

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

[0002] Lithium batteries are primary batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They are different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. With the continuous advancement of technology, the recycling technology of lithium batteries is becoming increasingly sophisticated. Filter presses are devices suitable for lithium battery recycling.

[0003] An existing lithium battery recycling filter press device (Announcement No.: CN220604766U) has at least the following disadvantages: the above-mentioned device compresses the extrusion spring through the movement of the push rod, and the extrusion spring pushes the pushing cylinder to move, and then pushes the push plate to press the filter frame, so that multiple filter press frames form a whole for filtration; at the same time, the continued movement of the push rod will push the piston plate to move, thereby filling the filter press medium in the pushing cylinder into the extrusion cavity of the extrusion cloth, causing the extrusion cloth to expand for filtration. However, after the filtration is completed, the filter cake is easy to adhere to one side of the filter plate, and the staff needs to scrape off the filter cake adhered to the filter plate, which is time-consuming and labor-intensive, and reduces the filtration efficiency of the filter press. For this reason, we propose the present utility model. Utility Model Content

A second spring 209 is wrapped around the outer circular wall of the connecting shaft 208, and both ends of the second spring 209 are in contact with the inner top surface of the mounting groove 207 and the top surface of the fixed plate 203.

[0025] In this embodiment, a second motor is fixed on both sides of the filter press body 1, and a second cam 301 is rotatably set inside the two mounting grooves 207. The outer circular wall surface of the second cam 301 is in contact with the bottom surface of the fixed plate 203.
