Description

Technical Field

[0001] This utility model relates to the field of lead paste recycling technology, specifically to a lead-acid battery plate lead paste recycling device. Background Technology

[0002] Lead-acid batteries are one of the most widely used secondary power sources in the world, and their scrap volume is increasing year by year. The lead paste (mainly composed of PbSO4, PbO2, Pb, etc.) attached to the plates accounts for about 30% to 40% of the battery weight. If it cannot be efficiently recycled, it will not only cause a huge waste of valuable metals, but also bring serious risks of heavy metal pollution.

[0003] In the prior art, utility model patent CN212625763U discloses a "waste electrode plate lead paste recycling device". This device uses a mechanical structure of a grid plate, a sliding channel, and an inclined collection tank to allow the lead paste to slide off naturally under gravity, thereby reducing the accumulation of lead paste clumps. However, the inventors of this application have found in long-term production practice that the above-mentioned device still has the following shortcomings: the recycling method is singular, relying solely on gravity separation, which cannot completely peel off the dense and strongly adhered lead paste from the electrode plate surface, resulting in a low recycling rate. The lead paste enters the collection tank in a free-fall manner, easily mixing in impurities such as separator paper and plastic fragments. Without deep impurity removal and electrochemical reduction of the lead paste, the recovered lead paste has a high impurity content (total impurities such as Cu, Fe, and Zn ≥ 0.25%), making it difficult to directly reuse in the paste-making process.

[0004] The aforementioned defects severely restrict the green and large-scale development of the lead-acid battery industry. Therefore, developing a battery with high recovery rate and low impurities has become an urgent technical challenge for the industry. Utility Model Content

The electrolytic deposition component includes an electrolytic cell, a cathode plate, and an anode plate. The electrolytic cell contains electrolyte. The anode plate is installed inside the electrolytic cell, and the cathode plate is placed inside the electrolytic cell. The power supply in the distribution box is electrically connected to the anode plate and the cathode plate respectively. A hoisting basket is placed inside the electrolytic cell. The basket contains numerous lead-acid battery plates; the cleaning components include a cleaning tank, an ultrasonic generator, and multiple ultrasonic transducers. The cleaning tank is located on one side of the electrolytic cell and contains cleaning fluid. Each ultrasonic transducer is fixedly installed on the outer wall of the cleaning tank, and the ultrasonic generator is electrically connected to each ultrasonic transducer. The lifting components are connected to the basket and the cathode plate via transmission. The lifting components drive the basket to move into or out of the electrolytic cell; the lifting components drive the cathode plate to move into the cleaning tank.

[0007] Optionally, the lifting components include an I-beam, a first electric hoist, and a second electric hoist, with both ends of the I-beam fixedly installed to the wall; both the first and second electric hoists are mounted on the I-beam; the lifting end of the first electric hoist is connected to the suspended platform via a transmission; the lifting end of the second electric hoist is connected to the cathode plate via a transmission, and the connection between the lifting end of the second electric hoist and the cathode plate is made of insulating material.

[0008] Optionally, both the first and second electric hoists are running electric hoists.

[0009] Optionally, the power distribution box and the cleaning tank are both installed on the ground foundation. A control board is fixedly installed inside the power distribution box.

[0014] (III) Beneficial Effects This utility model provides a lead-acid battery plate lead paste recycling device, which has the following beneficial effects: 1. Significantly improved recovery rate: Through the synergy of the electrolytic deposition component and the lifting component, the cathode plate and anode plate first achieve deep stripping of lead paste in the electrolytic cell through the electrochemical reaction of PbSO4→Pb2+→Pb. Pure lead is continuously deposited on the surface of the cathode plate, which effectively improves the stripping efficiency. At the same time, the ultrasonic cavitation effect completely removes the residual lead paste, and the overall recovery rate is effectively improved, solving the technical problem of insufficient gravity separation and recovery in the existing technology.

[0015] 2. Significantly reduced impurity content: During electrolysis, impurity ions such as Cu, Fe, and Zn, whose standard electrode potentials differ significantly from lead, preferentially undergo anodic oxidation or precipitate as hydroxides. Only high-purity lead (purity ≥99.99%) is deposited at the cathode, which can be directly recycled in the paste-making process. At the same time, ultrasonic cleaning further removes impurities such as sulfates and organic matter from the electrode surface, significantly reducing the total amount of impurities in the lead paste and fundamentally solving the problem of high impurity levels and limited utilization of recycled lead paste.

[0031] In the electrolytic deposition components: Electrolytic cell 1 is welded from 8mm thick 316L stainless steel plate, with external dimensions of 2000mm (length) × 1200mm (width) × 1000mm (depth). It is lined with a 5mm thick vinyl ester resin anti-corrosion layer, providing excellent corrosion resistance, heat resistance, and insulation. The density of the material contained within the cell is 1.28g / cm³. 3The fluorosilicic acid electrolyte is kept at a height of 150mm from the tank opening. The anode plate 6 is a 1200mm × 800mm × 6mm Pb-Sb alloy plate (3% Sb content), bolted to the insulating ceramic lugs on the inner walls of the two long sides of the electrolytic cell 1 to ensure insulation between the anode and the tank body. The cathode plate 19 consists of a horizontal plate 1901 (1200mm × 200mm × 10mm) and ten vertical plates 1902 (800mm × 100mm × 3mm). The vertical plates 1902 are welded at equal intervals to the lower surface of the horizontal plate 1901, forming a comb-like structure to increase the cathode area and facilitate uniform lead deposition. The DC power supply in the distribution box 11 outputs a voltage of 2.2V and a current density of 180A / m³. 2 Its positive electrode is electrically connected to the anode plate 6 through a copper busbar (or other conductors, etc.), and its negative electrode is electrically connected to the cathode plate 19 through a flexible copper braided strip (or other conductors, etc.), thus realizing an electrolysis circuit.

[0032] The suspended platform 5 is welded from polypropylene homopolymer sheets (or other sheets, etc.), with external dimensions of 1800mm (length) × 1000mm (width) × 600mm (height). It has 10mm × 20mm elongated holes evenly distributed on the bottom and sides to facilitate electrolyte flow. Four 316L lifting lugs are located along the upper edge of the platform 5 for connection to the lifting components. During operation, the disassembled electrode plates are neatly stacked inside the platform 5, with a spacing of ≥20mm between plates to prevent short circuits.

[0033] In the hoisting components: I-beam 2 is made of I32b hot-rolled I-beam, and both ends are fixed to the embedded steel plates of wall 21 by chemical anchors. The installation height is 6m from the ground foundation 20, and the span covers the electrolytic cell 1 and the cleaning tank 12. The first electric hoist 3 (model DRH-2000, rated load 2t) is suspended from the flange of I-beam 2 by a running trolley and can move longitudinally along I-beam 2; its hook is connected to the four lifting lugs of the basket 5 by a Φ16mm steel wire rope, realizing the transfer of the basket 5 between the electrolytic cell 1 and the loading station. The second electric hoist 4 (model DRH-500, rated load 500kg) is also installed on I-beam 2. The hook is connected to the two lifting lugs of the cross plate 1901 of cathode plate 19 by an insulated lifting device (epoxy resin clamp) to ensure that cathode plate 19 is insulated from I-beam 2. When electrolysis is complete and the lead layer thickness deposited on the surface of the cathode plate 19 reaches the set value (approximately 12 mm), the second electric hoist 4 lifts the cathode plate 19 above the cleaning tank 12, and then lowers it so that the cathode plate 19 is completely immersed in the cleaning solution for ultrasonic cleaning.

[0034] In the cleaning components: the cleaning tank 12 is welded from a 4mm thick titanium alloy plate, with dimensions of 1500mm long × 800mm wide × 800mm deep, resistant to strong acids and with high ultrasonic transmission efficiency. The tank contains a water-based weak acid cleaning solution (pH≈4.5), with the liquid level 100mm from the tank opening. Each ultrasonic transducer 18 (frequency 28kHz, single power 100W) is evenly fixed to the outer wall of the cleaning tank 12 with bolts. The ultrasonic generator is placed in the distribution box 11 and electrically connected to the transducers via an RF cable. When the cathode plate 19 is immersed in the cleaning solution, the ultrasonic generator outputs 1200W of electrical power. The transducer converts electrical energy into mechanical vibration energy, and the cavitation bubbles instantly collapse to generate micro-jet streams, completely removing electrolyte residue and loose impurities adhering to the surface of the cathode plate 19. The cleaning time is approximately 3 minutes. Afterwards, the second electric hoist 4 lifts the cathode plate 19 out of the liquid, drains it, and sets it aside for later use.

[0035] A DN50 first drain pipe 9 is welded to the bottom of the long side wall of electrolytic cell 1 for discharging waste electrolyte; a DN40 first inlet pipe 7 is welded 300mm from the bottom of the cell for replenishing fresh electrolyte. The first control valve 8 and the second control valve 10 are both electric ball valves, linked to the PLC control board in the distribution box 11 to achieve closed-loop control of the electrolyte level. A DN40 second drain pipe 16 is welded to the bottom of the short side wall of cleaning tank 12, and a DN40 second inlet pipe 14 is welded to the top, controlled by the third control valve 15 and the fourth control valve 17 respectively, to achieve timed replacement of the cleaning solution.

[0036] The distribution box 11 is floor-mounted on the ground foundation 20 and integrates a DC power supply, an ultrasonic generator, a PLC control board, and a frequency converter. The PLC communicates with the first electric hoist 3, the second electric hoist 4, and the electric ball valve via a Modbus bus. It presets process parameters: electrolysis time 90 min, ultrasonic cleaning time 3 min, and drainage time after the cathode plate is removed 1 min, enabling one-button start and automated operation.

[0037] Work process: (1) Loading: Manually load the disassembled electrode plates into the basket 5, and the first electric hoist 3 lifts the basket 5 into the electrolytic cell 1; (2) Electrolysis: The PLC starts the DC power supply, and an electric field is formed between the anode plate 6 and the cathode plate 19. PbSO4 and PbO2 in the lead paste are reduced to Pb2+ and deposited on the surface of the cathode plate 19. (3) Transfer: After electrolysis is completed, the first electric hoist 3 lifts the basket 5 out of the electrolysis cell 1 and sends it to the waste electrode plate collection area on the ground foundation 20. (4) Cleaning: The second electric hoist 4 moves the lead cathode plate 19 into the cleaning tank 12 and starts ultrasonic cleaning. (5) Discharge: After cleaning, the cathode plate 19 is hoisted to the melting and casting area, and the high-purity lead sheet can be peeled off by manual knocking. The cathode plate 19 can be recycled.
