Raw material tank equipment for producing lithium battery diaphragm

The utility model discloses raw material tank equipment for producing a lithium battery diaphragm, and belongs to the technical field of lithium battery diaphragm production. The device comprises a vertically-through tank body, an inner cover is arranged in the tank body, and the inner cover is integrally of a big-end-down structure and comprises an upper cover body and a lower cover body; wherein the lower cover body is positioned in the tank body, and the lower cover body extends out of the tank body; adsorption holes are formed in the tank body, and a filter screen is arranged in the tank body. According to the utility model, the small-caliber upper cover body is used as the feeding hole, so that the tight fit between the discharging part of the ton bag and the upper cover body can be ensured, and the possibility of powder escaping can be effectively reduced; even if a small amount of powder escapes outwards, the escaped powder can be recycled in time through the adsorption holes in the tank body.
