Description

Technical Field

[0001] The utility model relates to the technical field of electrowinning equipment, in particular to zinc, copper, lead and multi-metal electrowinning equipment. Background Art

[0002] In the field of metal smelting and recycling, electrowinning is a commonly used technology that uses the principle of electrolysis to extract or recover metals from solutions containing target metals. The application of electrowinning is particularly important in multi-metal systems such as zinc, copper, and lead.

[0003] Most of the existing electrowinning equipment adopts a fixed electrode structure, that is, a fixed anode and cathode are set in the electrolytic cell, and the electrolytic reaction is carried out by powering on. Although this method is simple and easy to implement, it is difficult to accurately control the precipitation order and precipitation amount of different metal ions when processing solutions containing multiple metal ions, resulting in low product purity and even the possibility of mixed metals, which reduces the quality and application value of the product. In view of this, a new type of zinc, copper and lead multi-metal electrowinning equipment is proposed. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a zinc-copper-lead multi-metal electrowinning equipment, in which the electrolysis of the two metals does not interfere with each other and the metal precipitation sequence can be accurately controlled.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a zinc-copper-lead multi-metal electrowinning equipment, including an electrolytic cell and a salt bridge, a T-shaped partition is arranged in the electrolytic cell, a zinc plate is arranged on one side of the electrolytic cell, and a conversion mechanism is arranged on the other side, a copper plate is arranged on one end of the conversion mechanism, and a lead plate is arranged on the other end, the conversion mechanism includes a bracket, a sprocket group is arranged on the bracket, a chain belt is arranged on the sprocket group, the chain belt is respectively connected to the copper plate and the lead plate, a rotating rod is arranged on the sprocket group, and the zinc plate is respectively connected to the copper plate and the lead plate through an electric switch.

[0006] In some embodiments, the T-shaped partition divides the electrolytic cell into three parts: a first space, a second space, and a third space, and each of the three parts is filled with a different solution.

[0007] In some embodiments, two conversion mechanisms are provided.

[0008] In some embodiments, a limit block is provided on the inner wall of the electrolytic cell.

[0009] In some embodiments, the end of the rotating rod is provided with anti-slip grooves.

[0010] In some embodiments, a motor is connected to the end of the rotating rod.

[0011] In summary, the utility model has the following beneficial effects:

[0012] The utility model utilizes the rotating rod of the conversion mechanism to respectively control the rotation of the sprockets near the copper plate and the lead plate in the sprocket group, and utilizes the gravity of the copper plate and the lead plate to realize mutual pulling between the two. When the copper plate falls, the lead plate rises, and when the lead plate falls, the copper plate rises. The two are converted to each other without interfering with each other, and the precipitation order of the metals is accurately controlled, so the purity of the product can be better controlled and the product quality can be improved.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3A zinc-copper-lead multi-metal electrowinning equipment comprises an electrolytic cell 1 and a salt bridge 15. A T-shaped partition 11 is arranged in the electrolytic cell 1. A zinc plate 3 is arranged on one side of the electrolytic cell 1, and a conversion mechanism 2 is arranged on the other side. A copper plate 4 is arranged on one end of the conversion mechanism 2, and a copper plate 4 is arranged on the other end. The conversion mechanism 2 comprises a bracket 21, a sprocket group 22 is arranged on the bracket 21, a chain belt 23 is arranged on the sprocket group 22, and the chain belt 23 is respectively connected with the copper plate 4 and the lead plate 5, and a rotating rod 24 is arranged on the sprocket group 22. The zinc plate 3 is respectively connected with the copper plate 4 and the lead plate 5 through an electric switch 17. When the operator performs electrolysis, he puts the zinc plate 3 into the electrolytic cell 1, and then installs the copper plate 4 and the lead plate 5 on the chain belt 23. If zinc-copper electrolysis is required, the operator turns on the electric switch 17 at the connection between the zinc plate 3 and the copper plate 4, and ensures that the electric switch 17 at the connection between the zinc plate 3 and the lead plate 5 is in the closed state, and then controls the rotation of the rotating rod 24. There are two rotating rods 24, which respectively control the rotation of the sprockets in the sprocket group 22 near the copper plate 4 and the lead plate 5. The rotating rod 24 drives the sprockets in the sprocket group 22 near the copper plate 4 to rotate, so that the copper plate 4 uses its own gravity to drop into the electrolyte in the electrolytic cell 1, and at the same time, the lead plate 5 moves upward under the pull of the chain belt 23, and will not contact with the solution in the electrolytic cell 1, so that zinc-copper electrolysis can be carried out. Similarly, when lead-zinc electrolysis is required, the operator turns off the electric switch 17 at the connection between the zinc plate 3 and the copper plate 4, turns on the zinc plate 3 and the lead plate 5, and rotates the sprockets. The electric switch 17 at the connection of the plate 5 is turned, and then the rotating rod 24 is rotated to control the rotation of the sprocket near the lead plate 5 in the sprocket group 22, so that the lead plate 5 uses its own gravity to descend and drives the chain belt to pull the copper plate 4. Before the lead plate 5 enters the solution of the electrolytic cell 1, the copper plate 4 has been pulled upward by the chain belt to leave the solution, so as to avoid the operator forgetting to turn off the electric switch 17 and causing both metals to be electrolyzed, affecting the electrolysis efficiency, that is, realizing lead-zinc electrolysis; the utility model uses the rotating rod 24 of the conversion mechanism 2 to control the rotation of the sprocket near the copper plate 4 and the lead plate 5 in the sprocket group 22 respectively, and uses the own gravity of the copper plate 4 and the lead plate 5 to realize the mutual pulling of the two. When the copper plate 4 falls, the lead plate 5 rises, and when the lead plate 5 falls, the copper plate 4 rises. The two convert to each other without interfering with each other, which can better control the purity of the product, accurately control the precipitation order of the metal, and improve the product quality.

[0019] In some embodiments, the T-shaped partition 11 divides the electrolytic cell 1 into three parts: a first space 12, a second space 13, and a third space 14, and each of the three parts is filled with a different solution. The first space 12 is filled with a zinc sulfate solution, the second space is filled with a copper sulfate solution, and the third space is filled with a sulfuric acid solution. The electrolysis of the three metals can be carried out separately, avoiding their possible mutual influence in the same solution, thereby ensuring the efficiency and purity of the electrolysis process.

[0020] In some embodiments, two conversion mechanisms 2 are provided. Two conversion mechanisms 2 are provided, which can improve the clamping strength of the copper plate 4 and the lead plate 5, and at the same time ensure stability when clamping the copper plate 4 and the lead plate 5, thereby preventing the copper plate 4 and the lead plate 5 from becoming skewed and touching other substances due to the clamping of a single conversion mechanism 2 and affecting electrolysis.

[0021] In some embodiments, a limit block 16 is provided on the inner wall of the electrolytic cell 1. The limit block 16 can assist the operator to quickly position the zinc plate 3, copper plate 4 and lead plate 5 when the operator places the zinc plate 3, copper plate 4 and lead plate 5 into the electrolytic cell 1 through the sprocket group 22, so as to avoid the zinc plate 3, copper plate 4 and lead plate 5 from tilting and falling into the electrolytic cell 1 when placing them, thereby delaying the work.

[0022] In some embodiments, the end of the rotating rod 24 is provided with anti-slip grooves, which can prevent the operator's hands from slipping when rotating the rotating rod 24, resulting in mistakes and affecting the electrolysis work. At the same time, the friction of the operator's rotation of the rotating rod 24 is enhanced to improve the operator's control over the rotation of the rotating rod 24, so that the conversion of the copper plate 4 and the lead plate 5 can be accurately controlled during electrolysis.

[0023] In some embodiments, a motor is connected to the end of the rotating rod 24. In order to facilitate the operation of the operator, a motor can be installed at the end of the rotating rod 24. The process and working time of the motor can be set through the existing program, thereby replacing manual rotation of the rotating rod 24. This not only saves manpower, but also improves the conversion efficiency of the electrolytic copper plate 4 and the electrolytic lead plate 5, thereby ensuring the electrolysis efficiency.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
