Description

Technical Field

[0001] The utility model belongs to the technical field of hydrometallurgy, relates to the production of electrolytic nickel, and specifically relates to a nickel cathode automatic operation and quality improvement device. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] Electrolytic nickel production adopts the insoluble anode diaphragm electrolytic production process, the anode is a titanium-coated lead dioxide anode or a titanium-coated iridium anode, and the cathode is a nickel starter. Under the action of direct current, after one cathode cycle, it can grow into electrolytic nickel of specified thickness and weight, so the nickel starter needs to be periodically placed in the tank and shipped out. The growth cycle of the nickel starter used is 24h or 48h, and the bottom and side edges are bent to varying degrees. It is very easy to scratch the diaphragm bag when the whole hoist is lowered, which restricts the realization of the overall placement of the nickel starter. At present, it is manually placed one by one.

[0004] ① The number of cathodes in an electrowinning cell is about 40-50. During manual operation, the nickel starting plates need to be taken, flattened and put into the cell one by one, which is labor-intensive.

[0005] ② When inserting the nickel starter, a series of actions such as standing, squatting, and bending over are required. It usually takes more than 300 squatting and standing up to complete the lowering of the nickel starter of an electrolytic deposition tank, which can easily cause lumbar muscle strain. In addition, the surface temperature of the electrolytic deposition tank is above 60°C. The high temperature and humid working environment is not conducive to the occupational health of employees.

[0006] ③ When working manually, it is necessary to stand or half-squat on the surface of the electrolytic deposition tank, which is about 0.8m above the ground. It is easy for people to slip and fall during the process of going up and down, and there are safety risks of being hit by objects and being burned by high temperatures.

[0007] ④ The edge of the nickel starting electrode is thin and sharp, and it is easy to be scratched when it is lowered into the diaphragm bag, resulting in increased bag consumption. It is inevitable that it will come into contact with the hands of the operators, which may easily cause personal injury.

[0008] ⑤ The entire process of placing the nickel starting electrode in the tank is purely manual, and the operation takes 40 minutes per tank, which prolongs the horizontal electrification time of the electrolytic tank, causing a decrease in the tank operation rate and affecting the utilization of the electrolytic nickel production capacity.

[0012] In one embodiment, the nickel cathode automated operation and quality improvement device is integrally formed of fiberglass material, and the bottom frame is a smooth semicircular chute.

[0013] In one embodiment, the bracket is horizontally connected to the opening clamp and is integrally formed.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1 and 2As shown, a nickel cathode automated operation and quality improvement device has a "U"-shaped appearance, including: two side frames respectively perpendicular to the ends of the horizontal chute, a bottom frame, an opening clamp 1, a bracket 2, a guide device 3, a limiting cone 4, a lateral support 5 and a lower liquid port 6. The opening card 1 is located at the upper end of the "U"-shaped frame, and its shape is a trumpet-shaped opening extending outward, which can fix the "U"-shaped frame to the upper part of the diaphragm frame; a platform of about 20mm is set on one side of the trumpet-shaped opening, which is a bracket 2 extending horizontally; the side frame is a smooth semicircular chute, and the guide device 3 is located inside the two side frames, for example, it can be a semicircular protrusion with a smooth transition, and 3-4 groups can be symmetrically set; the limiting cone 4 is placed at the semicircular bottom of each of the two side frames, which can be protruded outward for example 5mm, and one can be set in each of the two side frames to limit the left and right movement of the nickel starting electrode sheet; a 40mm wide lateral support 5 is set above the bottom frame (for example, 130mm away from the bottom of the "U"-shaped frame), which is vertically connected to the two side frames to enhance the stability of the structure. The lower liquid port 6 is located at the bottom of the bottom frame, for example, it can be two groups of parallel rectangular openings to form a hollow lower liquid port, which can avoid solution accumulation while ensuring strength.

[0030] In one embodiment, in order to ensure the corrosion resistance and stability of the nickel cathode automated operation and quality improvement device, fiberglass material can be used for one-piece molding with a thickness of 4 mm. The side frames and bottom frames are both semicircular chutes, which fit smoothly with the contact position inside the diaphragm bag, effectively protecting the diaphragm bag, bearing a higher weight, and easy to operate.

[0031] In one embodiment, in order to improve the problem of difficult observation of cathode liquid circulation, a 20mm platform bracket is set at one end of the opening clamp extending outward to the same width as the side groove, and the cathode liquid is lifted upward and placed on the bracket to avoid the influence of foam on circulation observation.

[0032] In one embodiment, in order to prevent the nickel starting electrode from tilting to one side during the insertion process, 3-4 groups of 3mm semicircular guide protrusions are symmetrically arranged on both sides of each side frame, and a 15mm high triangular limiting cone is arranged at the semicircular bottom of the side frame, so that the nickel starting electrode can smoothly enter the side frame along the guide protrusion. At the same time, the limiting cone can force it to be located in the center position, thereby improving the problem of granulation on the side edges of the electrolytic nickel.

[0033] In one embodiment, in order to ensure that the device is not easily deformed, a lateral support with a width of 40 mm is provided at a distance of 130 mm from the bottom of the bottom frame, which can improve the stability of the device and alleviate the granulation of the bottom edge of the electrolytic nickel.

[0034] In one embodiment, in order to reduce the labor intensity of employees at the job, a hollow-shaped liquid outlet is set at the bottom to effectively avoid solution accumulation. When replacing the solution, the solution can flow out through the liquid outlet, thereby optimizing job operations.

[0035] In one embodiment, a limiting cone is disposed in each of the two side frames, and the two limiting cones have the same horizontal height.

[0036] The specific working process of the utility model is as follows:

[0037] When in use, place the "U"-shaped frame inside the cathode chamber diaphragm bag, adjust the upper opening clamp 1 to fix it on the diaphragm frame, make fine adjustments left and right to make the "U"-shaped frame in the center of the diaphragm bag, and fully open it; place the cathode liquid circulation pipe on the upper part of the bracket 2, adjust it to a horizontal position, and the circulation pipe is about 10mm higher than the cathode liquid foam surface, so that the circulation can be clearly observed; the crane lifts the nickel starter sheet of the entire tank to the top of the electrolytic cell, and the precise positioning of the hoist and the internal space of the electrolytic cell is achieved through the cooperation of the positioning cone, and the nickel starter sheet of the entire tank is in the trumpet-shaped opening. Under the guidance of the clamp 1 and the two side frame guide devices 3, it is lowered into the diaphragm bag of each cathode area. At the same time, with the cooperation of the limiting cone 4, the nickel starting electrode is forced to be located in the center position of the "U"-shaped frame, thereby achieving a breakthrough in the mechanized overall lowering of the nickel starting electrode, solving the problems of easy scratching of the diaphragm bag and high labor intensity, high safety risks, low operating efficiency and low degree of mechanization in the process of manual lowering of each piece. When replacing the device, the solution in the cathode chamber can flow out along the liquid port 5 under the bottom frame, which effectively avoids solution accumulation, optimizes operation and reduces job labor intensity.
