Title:
SAFE REACTOR FOR LEACHING OF WASTE BATTERY POWDER AND CAPABLE OF CONTROLLING HYDROGEN CONCENTRATION
Document Type and Number:
WIPO Patent Application WO/2022/252604
Kind Code:
A1
Abstract:
Disclosed in the present invention is a safe reactor for leaching of waste battery powder and capable of controlling hydrogen concentration, comprising a platform, a rotary acid pumping cylinder, and a delivery pipe; the platform is provided with a support frame and a driving device; the rotary acid pumping cylinder is hingedly connected to the support frame; the driving device is used for driving the rotary acid pumping cylinder to rotate; the delivery pipe is mounted on the platform and passes through the rotary acid pumping cylinder; a screw used for material pushing is disposed in the delivery pipe; the delivery pipe comprises a pouring section located in the rotary acid pumping cylinder; the upper part of the pouring section is provided with a pouring port; the bottom of the pouring section is provided with acid leakage holes; at least one acid pumping piece is installed on the inner wall of the rotary acid pumping cylinder.In the present invention, cooperation of the screw and the delivery pipe are used to effectively prevent external air from communication with the air in the rotary acid pumping cylinder, thereby avoiding change in the volume concentration of hydrogen in the rotary acid pumping cylinder caused by mutual communication of air, preventing hydrogen from overflowing to the outside, and facilitating control of the volume concentration of hydrogen.
