Abstract

Disclosed is a dust-proof safe feeding device for power battery black powder acid leaching feeding, including a leaching tank, a blanking grid and a material shaking assembly, where the leaching tank includes a feeding port; the blanking grid is mounted in the feeding port, and the blanking grid is provided with a blanking hole; the material shaking assembly includes a material shaking member and a driving device, the material shaking member is movably arranged in the blanking hole, the driving device is connected with the material shaking member, and the driving device is configured to drive the material shaking member to move in the blanking hole.

First claim

The invention claimed is:

1. A dust-proof safe feeding device for power battery black powder acid leaching feeding, comprising:
a leaching tank comprising a feeding port;
a blanking grid mounted in the feeding port, wherein the blanking grid is provided with a blanking hole; and
a material shaking assembly comprising a material shaking member and a driving device, wherein the material shaking member is movably arranged in the blanking hole, the material shaking assembly further comprises a material shaking plate, the material shaking member is mounted on the material shaking plate, the driving device comprises a plurality of eccentric wheels and a motor, the material shaking plate is mounted on the leaching tank through the plurality of eccentric wheels, and the motor is connected to the eccentric wheels and configured to drive the eccentric wheels to rotate so as to drive the material shaking member to move in the blanking hole.

2. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 1 , wherein the material shaking member is in a “U” shape.

3. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 1 , wherein the material shaking member is in a plate shape, and the material shaking member is provided with a plurality of material guiding through holes.

4. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 3 , wherein the material guiding through hole is provided with a bulge at a bottom portion, and two ends of the bulge are inclined planes.

5. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 1 , further comprising an opening and closing assembly, wherein the opening and closing assembly is mounted in the feeding port and is located below the blanking grid, the opening and closing assembly comprises a feeding rotor rotatably mounted in the feeding port, the feeding rotor is provided with at least one holding tank, and an outer surface of the feeding rotor abuts against an inner surface of the feeding port, so that the feeding rotor seals the feeding port.

6. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 5 , wherein the opening and closing assembly further comprises a fixation cylinder, the fixation cylinder is mounted in the feeding port and an outer surface of the fixation cylinder is hermetically and fixedly connected with the inner surface of the feeding port, the fixation cylinder is provided with a feed hole and a discharge hole communicated with the feeding port, the feeding rotor is located in the fixation cylinder, and the outer surface of the feeding rotor abuts against an inner surface of the fixation cylinder.

7. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 6 , wherein the feeding rotor comprises an opening and closing plate and an arc-shaped plate, the arc-shaped plate is arranged at two ends of the opening and closing plate, the arc-shaped plate and the opening and closing plate enclose the holding tank, the feeding port and the discharge hole are both arc-shaped openings, and an arc length between two ends of the arc-shaped plate is longer than that between two ends of the arc-shaped opening.

8. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 7 , wherein the arc-shaped plate is provided with a balance hole, a cross section of the balance hole is tapered, and a large hole end of the balance hole is close to an inner wall of the fixation cylinder.

9. The dust-proof safe feeding device for power battery black powder acid leaching feeding according to claim 1 , further comprising a gas extraction device mounted on the leaching tank and being in fluid communication with the leaching tank, wherein the gas extraction device is configured to extract gas in the leaching tank.
