Abstract

The invention discloses a waste battery powder leaching safety reaction tank with controllable hydrogen concentration. The waste battery powder leaching safety reaction tank comprises a rack, a rotary acid pumping cylinder and a conveying pipe, wherein the rack is provided with a supporting frame and a driving device; the rotary acid pumping cylinder is hinged to the supporting frame; the driving device is used for driving the rotary acid pumping cylinder to rotate; the conveying pipe is mounted on the rack and penetrates through the rotary acid pumping cylinder; a screw rod for pushing materials is arranged in the conveying pipe; the conveying pipe comprises an irrigation section located in the rotary acid pumping cylinder; an irrigation opening is formed in the upper portion of the irrigation section; acid leakage holes are formed in the bottom of the irrigation section; and at least one acid pumping piece is installed on the inner wall of the rotary acid pumping cylinder. According to the waste battery powder leaching safety reaction tank, the screw rod cooperates with the conveying pipe, so that communication between external atmosphere and air in the rotary acid pumping cylinder is effectively blocked, then the situation that the volume concentration of hydrogen in the rotary acid pumping cylinder is changed due to mutual air communication is avoided, the hydrogen is prevented from overflowing outwards, and the volume concentration of the hydrogen is convenient to control.

Description

technical field [0001] The invention relates to the technical field of recycling in the new energy material industry, in particular to a safe reaction tank for leaching waste battery powder with controllable hydrogen concentration. Background technique [0002] With the continuous supply of environmental protection needs, it is necessary to recycle and utilize a large number of decommissioned waste batteries. Waste batteries contain many important rare metal elements. At present, the recovery rate of lithium, nickel, cobalt, manganese, etc. can reach more than 99%. Recycling of batteries is not only beneficial to the recycling of resources, but also alleviates the supply problem of raw materials and reduces costs. At the same time, waste batteries contain highly toxic substances and volatiles such as lithium hexafluorophosphate. If these waste batteries are not properly disposed of, they will have a negative impact on the ecological environment. At the same time, if the use...
