Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic zinc devices, and more specifically relates to a residual zinc plate processing device. Background Art

[0002] During the manufacturing process of zinc plates in smelters, residual zinc plates are produced due to various reasons such as production operation, equipment wear, and material problems. The residual zinc plates produced usually need to be placed in a remelting tank for treatment in order to be recycled. The treatment process is as follows: Figure 5 However, due to the large fluctuations in the electrolytic cell process of the smelter, a large amount of residual zinc plates are produced. The existing remelting tanks are difficult to meet the processing needs of the residual zinc plates, which leads to an increase in the processing cost of zinc plate manufacturing in the smelter and also causes a waste of resources.

[0003] Although simply adding a re-dissolution tank can improve the processing capacity of residual zinc plates, the investment cost will become higher and the difficulty of operation and maintenance will increase. Therefore, before the electrolytic cell process is optimized to reduce the generation of residual zinc plates, a residual zinc plate processing device is needed that can solve the problem of residual zinc plate processing and is easy to modify and has low modification costs. Utility Model Content

[0004] In order to overcome the problems existing in the background technology, the utility model patent provides a residual zinc plate processing device, which can solve the problem of processing residual zinc plates, and is easy to modify and has low modification costs.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions: a residual zinc plate processing device is arranged and installed next to the waste liquid circulation pool of electrolytic zinc in a smelter, comprising: a treatment pool, a siphon, a liquid extraction pump, a residual zinc plate hanger, and a controller; the siphon connects the treatment pool and the waste liquid circulation pool, and is used to transport the solution in the waste liquid circulation pool to the treatment pool, the liquid extraction pump connects the treatment pool and the waste liquid circulation pool, and is used to transport the overflow in the treatment pool to the waste liquid circulation pool; the residual zinc plate hanger is installed on the side of the treatment pool, and an electric hanging basket and an agitator are provided on the residual zinc plate hanger, which are located directly above the treatment pool; the controller is connected to the liquid extraction pump, the electric hanging basket, and the agitator.

[0006] Furthermore, a liquid depth sensor connected to the controller is provided on the inner wall of the treatment tank, and the installation position of the liquid depth sensor is lower than the height of the siphon tube outlet in the treatment tank.

[0007] Furthermore, filter plate I and filter plate II for filtering impurities are provided at the left and right ends of the treatment pool; the outlet of the siphon tube is located in the cavity formed by filter plate I and the left side wall of the treatment pool, and the liquid pump is located in the cavity formed by filter plate II and the right side wall of the treatment pool.

[0008] Beneficial effects of the utility model: The utility model transports the solution in the waste liquid circulation pool to the treatment pool by arranging a siphon tube, and then transports the treated solution back to the waste liquid circulation pool by arranging a liquid extraction pump, so as to recycle the waste liquid. The residual zinc plate is treated by cooperating with the liquid extraction pump and the siphon tube to recycle the waste liquid, which effectively solves the problem of the residual zinc plate being difficult to treat. The utility model can make the residual zinc plate fully contact with the solution and accelerate the reaction efficiency by arranging an electric hanging basket and an agitator. At the same time, the utility model is easy to modify and the modification cost is low. It has been proved in practice that the construction cost of the utility model is low and the construction time is short. In addition, the utility model has high treatment efficiency for the residual zinc plate, which effectively reduces the risk of large fluctuations in the electrolytic cell process.

[0020] like Figure 1-5As shown, a residual zinc plate processing device is installed next to the waste liquid circulation pool 9 of electrolytic zinc in a smelter, including: a processing pool 1, a siphon 2, a liquid pump 3, a residual zinc plate hanger 4, an electric hanging basket 5, an agitator 6, a controller 7, a liquid depth sensor 8, and a waste liquid circulation pool 9.

[0021] The treatment pool 1 is made of acid-resistant bricks, and steel plates are provided on the periphery of the acid-resistant bricks for reinforcement. The treatment pool 1 is arranged next to the waste liquid circulation pool 9 of the electrolytic zinc smelter.

[0022] The siphon tube 2 connects the treatment tank 1 and the waste liquid circulation tank 9, and transports the solution in the waste liquid circulation tank 9 to the treatment tank 1 through siphon action. After the waste liquid is transported to the treatment tank 1, the residual zinc plate is dissolved. The setting of the siphon tube 2 is convenient and quick.

[0023] The liquid extraction pump 3 is connected to the treatment pool 1 and the waste liquid circulation pool 9 through a pipeline, and is used to transport the solution in the treatment pool 1 back to the waste liquid circulation pool 9. By arranging the liquid extraction pump 3 in conjunction with the siphon 2, the recycling of waste liquid is achieved.

[0024] The residual zinc plate hanger 4 is installed on the side of the treatment pool 1. An electric hanging basket 5 and an agitator 6 are provided on the residual zinc plate hanger 4, which are located directly above the treatment pool 1. The electric hanging basket 5 includes: a hanging basket, a steel wire rope, and a drive motor, and the lifting and lowering of the hanging basket is controlled by the drive motor. The hanging basket is composed of a steel mesh plate and is used to place the residual zinc plate. A number of vertically placed steel mesh plates 501 are also provided in the hanging basket to place the residual zinc plate vertically so that the residual zinc plate is fully in contact with the solution. At the same time, by using the electric hanging basket 5 to place the residual zinc plate, the safety of production can be improved. The agitator 6 includes: an electric lifting rod 601 and an electric agitator 602. The electric agitator 602 is installed below the electric lifting rod 601. By driving the electric lifting rod 601, the electric agitator 602 is driven to rise and fall. By driving the electric agitator 602, the treatment pool 1 is stirred so that the residual zinc plate is fully in contact with the solution, thereby accelerating the reaction efficiency.

[0025] The controller 7 is a PLC controller, which is connected to the liquid pump 3, the electric hanging basket 5, and the stirrer 6. The controller 7 controls each device in a unified manner, which is convenient for the staff to operate.

[0026] Preferably, a liquid depth sensor 8 connected to a controller 7 is provided on the inner wall of the treatment tank 1, and the installation height of the liquid depth sensor 8 is lower than the height of the outlet of the siphon tube 2 in the treatment tank. By providing the liquid depth sensor 8 to monitor the solution height in the treatment tank 1, when the solution height reaches a set value, the control drives the liquid extraction pump 3 to extract the liquid, thereby preventing excessive solution in the treatment tank 1 from interrupting the siphoning effect of the siphon tube 2. At the same time, the solution after reacting with the residual zinc plate will also be re-transported back to the waste liquid circulation tank 9 for subsequent waste liquid recycling treatment.

[0027] Preferably, filter plates I 101 and II 102 are provided at the left and right ends of the treatment tank 1 for filtering impurities. Filter plates I 101 and II 102 are two stainless steel mesh sheets. The outlet of the siphon pipe 2 is located in the cavity formed by filter plate I 101 and the left side wall of the treatment tank 1. The solution transported to the treatment tank 1 through the siphon pipe 2 reacts with the residual zinc plate after passing through filter plate I 101. The liquid pump 3 is located in the cavity formed by filter plate II 102 and the right side wall of the treatment tank 1. The solution in the treatment tank 1 passes through filter plate II 102 and is then transported back to the waste liquid circulation tank 9 by the liquid pump 3.

[0028] The advantages of the present invention are as follows: the present invention transports the solution in the waste liquid circulation pool 9 to the treatment pool 1 by providing a siphon tube 2, and then transports the treated solution back to the waste liquid circulation pool 9 by providing a liquid extraction pump 3, thereby recycling the waste liquid and recycling the residual zinc plate. This effectively solves the problem of the residual zinc plate being difficult to handle. The present invention is provided with an electric hanging basket 5 and an agitator 6, so that the residual zinc plate can be fully contacted with the solution, thereby accelerating the reaction efficiency. At the same time, the present invention is easy to transform and has low transformation costs. Practice has proven that the construction cost of the present invention is about RMB 10,000, the construction time is short, and the present invention can process 150 residual zinc plates at a time, with high processing efficiency.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit the present invention. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope of protection of the present invention.
