Detailed implementation manners

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0026] In the description of the present invention, the meaning of "a plurality of" is more than two, and understandings such as "greater than", "less than", "exceeding", etc. do not include the present number. It should be understood that for the orientation description, such as the orientation or positional relationship indicated by "upper", "lower", "front", "rear", "left", "right", "middle", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0027] In the description of the present invention, unless otherwise clearly defined, words such as "installation" and "connection" should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0028] Refer to Figure 1As shown in the figure, the dust-proof and safety feeding device for acid leaching feeding of power battery black powder according to an embodiment of the present invention includes a leaching tank 100, a feeding grid 200, and a vibrating component 300. The leaching tank 100 includes a feeding port 110; the feeding grid 200 is installed in the feeding port 110, and the feeding grid 200 is provided with feeding holes 210; the vibrating component 300 includes a vibrating part 310 and a driving device 320. The vibrating part 310 is movably arranged in the feeding holes 210, and the driving device 320 is connected to the vibrating part 310. The driving device 320 drives the vibrating part 310 to move in the feeding holes 210.

[0029] For example, as Figure 1 shown, one end of the leaching tank 100 is a conveying pipeline, the feeding port 110 is located at the upper end of the conveying pipeline, and the feeding grid 200 is installed in the feeding port 110. As Figure 2 shown, there are multiple feeding holes 210, and the number of vibrating parts 310 corresponds to the number of feeding holes 210. Since the feeding port 110 of the pickling equipment is large and is provided with a feeding grid 200 to effectively protect the operator, the operator is prevented from falling into the feeding port 110 and getting into danger; due to the provision of the feeding grid 200, when there is too much battery powder, a bridging phenomenon is likely to occur, and then the battery powder cannot enter the leaching tank 100. As Figure 3 、 4 shown, the vibrating part 310 of the present invention is movably arranged in the feeding holes 210. When bridging occurs, the driving device 320 drives the vibrating part 310 to move up and down, back and forth, or up and down and back and forth in the feeding holes 210. The movement of the vibrating part 310 eliminates the bridging phenomenon of the battery powder and prevents the battery powder from being blocked in the feeding port 110. The combination of the feeding grid 200 and the vibrating part 310 prevents the battery powder from being blocked in the feeding port 110 and at the same time acts as a protective fence to prevent the operator from falling into the feeding port 110.

[0030] In some embodiments of the present invention, the vibrating part 310 is in a "U" shape. As Figure 3 shown, the "U" shape helps the battery powder to fall quickly.

[0031] In some embodiments of the present invention, as Figure 4 shown, the vibrating part 310 is plate-shaped, and the vibrating part 310 is provided with a plurality of material guiding through holes 311.

[0032] In a further embodiment of the present invention, as Figure 4 、 5 shown, a protrusion 3111 is provided at the bottom of the material guiding through hole 311, and both ends of the protrusion 3111 are inclined surfaces. The left and right ends of the protrusion 3111 are inclined surfaces, and the inclined surface structure helps the battery powder to fall.

[0033] In a further embodiment of the present invention, as Figure 1As shown, the vibrating component 300 further includes a vibrating plate 330. The vibrating member 310 is installed on the vibrating plate 330. The driving device 320 includes a plurality of eccentric wheels 321 and a motor 322. The vibrating plate 330 is installed on the leaching tank 100 through the plurality of eccentric wheels 321, and the motor 322 drives the eccentric wheels 321 to rotate. The vibrating plate 330 is connected to the eccentric wheels 321. The motor 322 drives the eccentric wheels 321, and then drives the vibrating plate 330 to move, so that the vibrating rack moves back and forth and up and down relative to the blanking grid 200. Such a structure is simple and convenient for maintenance. For example, one of the eccentric wheels 321 is installed on the leaching tank 100, the motor 322 is installed on the leaching tank 100 and drives the above-mentioned eccentric wheel 321. One end of the vibrating plate 330 extends into the feeding port 110 and is installed in the feeding port 110 through other eccentric wheels 321, and the other end of the vibrating plate 330 is connected to the motor 322.

[0034] In a further embodiment of the present invention, as Figure 1 shown, it further includes an opening and closing component 400. The opening and closing component 400 is installed in the feeding port 110 and is located below the blanking grid 200. The opening and closing component 400 includes a feeding rotor 410 rotatably installed in the feeding port 110. The feeding rotor 410 is provided with at least one receiving groove 411. The outer surface of the feeding rotor 410 abuts against the inner surface of the feeding port 110, and then the feeding rotor 410 seals the feeding port 110.

[0035] There are still the following defects in the current process of putting battery powder into the pickling tank:

[0036] During the feeding process, it is easy to make the reactants accumulated in the reaction tank oxygen 3H2SO4 + H2O2 + 2LiCoO2 → 2CoSO4 + Li2SO4 + 4H2O + O2↑, because air will be generated during the feeding process. Opening the feeding port 110 during feeding will cause oxygen leakage. Oxygen discharged directly from the feeding opening is easy to cause danger and is not safe for the feeding personnel. The current feeding ports 110 are all open. In addition to the easy overflow of oxygen and lack of safety, and it is easy to cause dust when putting the dried battery powder, which is easy to cause air pollution and harm the health of the operating personnel.

[0037] The present invention is provided with an opening and closing component 400, so that the feeding process is fully sealed, thus avoiding oxygen leakage and dust.

[0038] For example, both ends of the feeding rotor 410 are hinged in the conveying pipeline. The feeding rotor 410 is driven to rotate by the motor 322. The receiving groove 411 is used to receive battery powder. The shape of the receiving groove 411 can be V-shaped, U-shaped or other shapes that can hold the battery.

[0039] During operation, when the notch of the receiving groove 411 faces upward, it receives the material. When the notch faces downward, the battery powder in the receiving groove 411 falls along the conveying pipeline into the leaching tank 100. The feeding rotor 410 rotates in a cycle to convey the battery powder continuously. Since the outer surface of the feeding rotor 410 abuts against the inner surface of the feeding port 110, the cycle of continuous feeding can maintain relative sealing.

[0040] In a further embodiment of the present invention, as Figure 1 , 6 shown, the opening and closing assembly 400 further includes a fixed cylinder 420. The fixed cylinder 420 is installed in the feeding port 110, and the outer surface of the fixed cylinder 420 is fixedly connected to the inner surface of the feeding port 110 in a sealed manner. The fixed cylinder 420 is provided with a feeding port 421 and a discharging port 422 that communicate with the feeding port 110. The feeding rotor 410 is located inside the fixed cylinder 420, and the outer surface of the feeding rotor 410 abuts against the inner surface of the fixed cylinder 420.

[0041] During operation, the driving device 320 drives the notch of the receiving groove 411 to face upward, and the battery powder enters the receiving groove 411 of the feeding rotor 410 through the feeding port 421. Then, the driving device 320 drives the notch of the receiving groove 411 to face downward, and the battery powder is poured out from the discharging port 422.

[0042] In a further embodiment of the present invention, as Figure 1 shown, the feeding rotor 410 includes an opening and closing plate 412 and an arc-shaped plate 413. The arc-shaped plates 413 are provided at both ends of the opening and closing plate 412. The arc-shaped plates 413 and the opening and closing plate 412 enclose the receiving groove 411. Both the feeding port 110 and the discharging port 422 are arc-shaped openings. The arc length between the two ends of the arc-shaped plate 413 is greater than the arc length between the two ends of the arc-shaped opening. The arc length between the two ends of the arc-shaped plate 413 being greater than the arc length between the two ends of the arc-shaped opening can ensure sealing when the feeding rotor 410 rotates, thereby avoiding oxygen leakage and dust generation.

[0043] In a further embodiment of the present invention, the arc-shaped plate 413 is provided with a balance hole (not shown in the figure). The cross-section of the balance hole is conical, and the large hole end of the balance hole is close to the inner wall of the fixed cylinder 420. By providing the balance hole, when the arc-shaped plate 413 is located at the discharging port 422 of the fixed cylinder 420 and blocks the lower opening, the balance hole can balance the atmospheric pressure inside and outside the leaching tank 100, and under the action of negative pressure, external air will flow into the leaching tank 100.

[0044] In a further embodiment of the present invention, as Figure 7 shown, a sealing strip 414 is installed at one end of the feeding rotor 410 that abuts against the inner wall of the fixed cylinder 420. By providing the sealing strip 414, the sealing effect between the feeding rotor 410 and the fixed cylinder 420 can be enhanced.

[0045] In a further embodiment of the present invention, asFigure 1 As shown, it further includes an air extraction device 500 installed on the leaching tank 100, and the air extraction device 500 is used to extract the gas inside the leaching tank 100. The air extraction device 500 continuously extracts the gas inside the leaching tank 100 to keep the inside of the leaching tank 100 under negative pressure. In this way, no dust will be discharged from the feeding port 110 during the rotation and feeding process of the rotary feeding rotor 410. At the same time, after collecting the dust with a dust collection bag at the outlet of the air extraction device 500, it can be continuously put into the leaching tank 100 from the feeding port 110.
