[0031] Reference will be made below Figure 1 to describe the lead electrolysis workshop 100 according to the embodiment of the first aspect of the present invention.

[0032] As Figure 1 shown, the lead electrolysis workshop 100 according to the embodiment of the present invention includes a first-span workshop 101, a second-span workshop 102, an electrolytic cell 1041, a cathode lead casting system, an anode casting system, an impurity removal system 108, and an anode and cathode crane (not shown).

[0033] Specifically, the first-span workshop 101 and the second-span workshop 102 are arranged in parallel along the front-rear direction, and the first-span workshop 101 is arranged adjacent to the front side of the second-span workshop 102. In the left-right direction, the first-span workshop 101 and the second-span workshop 102 are sequentially divided into a refined lead casting area 103, an electrolysis area 104, and a crude lead impurity removal area 105 (as Figure 1In the left-to-right direction shown, that is, the refined lead casting area 103 and the crude lead impurity removal area 105 are respectively located on the left and right sides of the electrolysis area 104. The cathodes produced by electrolysis are transported to the refined lead casting area 103, and the residual anodes produced are transported to the crude lead impurity removal area 105, avoiding cross operations and improving production efficiency.

[0034] Further, the electrolytic cell 1041 is arranged in the electrolysis area 104. The electrolytic cell 1041 spans the first-span workshop 101 and the second-span workshop 102 in the front-to-back direction. Compared with the lead electrolysis workshop in the related art, not only the double-span workshop setting method is adopted, but also the electrolytic cell 1041 spans two workshops. In this way, the length of the workshop in the left-to-right direction can be greatly reduced, thereby saving factory land and reducing equipment investment.

[0035] Further, a cathode lead casting system is arranged in the refined lead casting area 103. The cathode lead casting system is located in the first-span workshop 101 and / or the second-span workshop 102. In an alternative example, the cathode lead casting system is located in both the first-span workshop 101 and the second-span workshop 102. In another alternative example, the cathode lead casting system is located in either the first-span workshop 101 or the second-span workshop 102.

[0036] An anode casting system and an impurity removal system 108 are arranged in the crude lead impurity removal area 105. The anode casting system is located in the first-span workshop 101 and / or the second-span workshop 102. In an alternative example, the anode casting system is located in both the first-span workshop 101 and the second-span workshop 102. In another alternative example, the anode casting system is located in either the first-span workshop 101 or the second-span workshop 102. The impurity removal system 108 is located in the first-span workshop 101 and / or the second-span workshop 102. In an alternative example, the impurity removal system 108 is located in both the first-span workshop 101 and the second-span workshop 102. In another alternative example, the impurity removal system 108 is located in either the first-span workshop 101 or the second-span workshop 102. Overhead cranes for both anodes and cathodes are arranged in both the first-span workshop 101 and the second-span workshop 102. In this way, the length of the workshop in the left-to-right direction can be greatly reduced, thereby saving factory land and reducing equipment investment. Moreover, the operating efficiency between the electrolytic cell 1041 and the cathode lead casting system, the anode casting system, and the impurity removal system 108 can also be improved.

[0037] For the lead electrolysis workshop 100 according to the embodiment of the present invention, by adopting a double-span workshop arranged in parallel in the front-to-back direction, the electrolytic cell 1041 is distributed in the double-span workshop, saving the length of the workshop in the left-to-right direction, saving equipment and thus workshop investment. Moreover, the refined lead casting area 103 and the crude lead impurity removal area 105 are distributed on the left and right sides of the electrolysis area 104, which can effectively avoid cross operations between processes and improve production efficiency and economic benefits.

[0038] According to an embodiment of the present invention, a cathode lead casting system includes a cathode rod drawing and washing unit 1061, a refined lead pot 1062, a lead ingot linear casting unit 1063, and a lead cathode manufacturing machine 1064. The cathode rod drawing and washing unit 1061 is arranged adjacent to the electrolytic cell 1041, and the cathode rod drawing and washing unit 1061 is located in the first-span workshop 101 and / or the second-span workshop 102. In this way, not only the floor area of the workshop is saved, but also the cathode rod drawing and washing unit 1061 can be operationally corresponding to the left and right of the electrolytic cell 1041 spanning across the two workshops, improving the operation efficiency.

[0039] Furthermore, the refined lead pot 1062, the lead ingot linear casting unit 1063, and the lead cathode manufacturing machine 1064 are all arranged in the first-span workshop 101 and are all located on the left side of the cathode rod drawing and washing unit 1061. The refined lead pot 1062 is located in the front of the lead ingot linear casting unit 1063 and the lead cathode manufacturing machine 1064. The refined lead pot 1062 is arranged adjacent to the cathode rod drawing and washing unit 1061 and the lead ingot linear casting unit 1063 respectively. In this way, it is more convenient to transport the cathode lead.

[0040] It can be understood that in the refined lead casting area 103, the refined lead pot 1062, the cathode rod drawing and washing unit 1061, and the lead ingot linear casting unit 1063 are configured. The produced cathode lead is directly transported to the refined lead pot 1062 through the cathode rod drawing and washing unit 1061 for melting and then ingot casting, without intermediate transfer, ensuring that the produced cathode lead is not contaminated and ensuring the product quality.

[0041] According to another embodiment of the present invention, the impurity removal system 108 includes an impurity removal pot 1081 and a residual electrode washing unit 1082. The residual electrode washing unit 1082 is located in the first-span workshop 101 and / or the second-span workshop 102. The residual electrode washing unit 1082 is arranged adjacent to the electrolytic cell 1041. The impurity removal pot 1081 is located on the right side of the residual electrode washing unit 1082. The produced residual electrodes can be directly returned to the impurity removal pot 1081 through the residual electrode washing unit 1082 for impurity removal and then remelted into anode plates, reducing the material transfer distance and the number of transfer times in the crude lead impurity removal area 105.

[0042] When the residual electrode washing unit 1082 spans across the first-span workshop 101 and the second-span workshop 102 (i.e., the residual electrode washing unit 1082 is located in the first-span workshop 101 and the second-span workshop 102), it can be positionally corresponding to the electrolytic cell 1041 on the right side of the electrolytic cell 1041, which is more convenient for transporting the residual electrodes and saves the floor area of the workshop.

[0043] Such as Figure 1As shown, according to an alternative example of the present invention, the anode casting system includes a linear anode plate casting unit 1071 and a lead melting pot 1072. The linear anode plate casting unit 1071 is arranged in the first-span workshop 101. The linear anode plate casting unit 1071 is located on the right side of the scrap anode washing unit 1082, and the lead melting pot 1072 is located on the front side of the linear anode plate casting unit 1071. Further, the lead melting pot 1072 is arranged adjacent to the linear anode plate casting unit 1071, which can shorten the lead liquid transportation distance and improve the casting efficiency and qualification rate of the anode plates.

[0044] Further, the lead melting pot 1072 and the impurity removal pot 1081 are arranged in a straight line in the left-right direction, which can prevent the lead liquid after impurity removal from being contaminated again during the transportation process and improve the impurity removal efficiency.

[0045] Optionally, the impurity removal pot 1081 is located on the left side of the lead melting pot 1072. As Figure 1 shown, there are a total of 5 lead melting pots 1072 and impurity removal pots 1081, including 2 impurity removal pots 1081, and the 2 impurity removal pots 1081 are arranged close to the scrap anode washing unit 1082, and there are 3 lead melting pots 1072. As Figure 1 shown, according to another alternative example of the present invention, a cathode and anode plate spacing unit 109 is provided in the crude lead impurity removal area 105. In the left-right direction, the cathode and anode plate spacing unit 109 is located between the scrap anode washing unit 1082 and the linear anode plate casting unit 1071, and the cathode and anode plate spacing unit 109 straddles the first-span workshop 101 and the second-span workshop 102.

[0046] It can be understood that the cast anode plates and cathode plates are respectively transported to the cathode and anode plate spacing unit 109 for reasonable spacing arrangement, and then hoisted into the electrolytic cell 1041 of the corresponding workshop by the cathode and anode crane. In this way, the cathode plates and anode plates can be arranged at a reasonable spacing in advance before being hoisted into the electrolytic cell 1041, improving the operation efficiency. The conveying chains of the cathode and anode plate spacing unit 109 and the scrap anode washing unit 1082 both pass through the double-span workshop, and the cathode and anode crane in any workshop span can hoist the cathode and anode required for electrolysis into the electrolytic cell 1041 of the corresponding workshop located behind the cathode and anode plate spacing unit, saving equipment investment.

[0047] According to still another embodiment of the present invention, a cathode and anode plate support frame 110 is provided in the crude lead impurity removal area 105. The cathode and anode plate support frame 110 is located behind the cathode and anode plate spacing unit 109 to facilitate the use of the cathode and anode crane to place the cathode plates and anode plates on the cathode and anode plate spacing unit 109 for spacing arrangement. The cathode and anode plate support frame 110 is located in the second-span workshop 102, and the redundant anode plates and cathode plates after casting can be placed on the cathode and anode plate support frame 110 for standby, and the operation time of each unit can be flexibly adjusted according to the electrolysis operation cycle.

[0048] As Figure 1 shown, according to an optional embodiment of the present invention, an electrolysis control system 111 and an acid mist purification system 112 are provided in the electrolysis area 104. Both the electrolysis control system 111 and the acid mist purification system 112 are located on the front side of the electrolytic cell 1041. The electrolysis control system 111 and the acid mist purification system 112 are distributed in the electrolysis area 104 in the left - right direction. Through the electrolysis control system 111, the automation of lead electrolysis control can be improved, intelligent operation can be realized, and centralized management is facilitated. Through the acid mist purification system 112, the acid mist generated during the electrolysis process can be collected, reducing the escape of HF acid (hydrofluoric acid) in the electrolysis area 104 and improving the working environment of the workshop.

[0049] Furthermore, a special gas collection pipeline and ventilation facilities are provided below the electrolytic cell 1041, preventing the escape of acidic waste gas and improving the working environment.

[0050] According to an optional embodiment of the present invention, an electrolyte circulation system and an electrolytic anode mud treatment system 114 are provided at the rear side of the electrolysis area 104. The electrolyte circulation system and the electrolytic anode mud treatment system 114 are distributed in the electrolysis area 104 in the left - right direction. Through the electrolyte circulation system, the recycling of the electrolyte can be realized, improving economic benefits. Through the electrolytic anode mud treatment system 114, the residues of the anode are treated, improving the working environment.

[0051] Furthermore, a product lead ingot temporary storage area 115 is also provided in the refined lead casting area 103, eliminating the need for a separate product storage warehouse, saving construction investment and reducing production costs.

[0052] In the lead electrolysis workshop 100 of the embodiment of the present invention, the crude lead impurity removal area 105 is arranged adjacent to the electrolysis area 104. Whether it is the casting of lead anode plates or the row spacing of anode and cathode plates, automated operations can be carried out through the arranged various units, avoiding cross - operations, reducing material handling, and improving production efficiency.

[0053] In the lead electrolysis workshop 100 of the embodiment of the present invention, the lead electrolysis workshop 100 is divided into a crude lead impurity removal area 105, an electrolysis area 104, and a refined lead casting area 103. A double - span workshop is adopted, and through reasonable layout, automated non - cross operations for each process are realized. Specifically, a lead melting pot 1072, an impurity removal pot 1081, an anode plate straight - line casting unit 1071, an anode and cathode plate row - spacing unit 109, and a residual electrode washing unit 1082 are provided in the crude lead impurity removal area 105. The anode plate straight - line casting unit 1071, the anode and cathode plate row - spacing unit 109, and the residual electrode washing unit 1082 are all arranged in the double - span workshop. The anode and cathode plates are lifted into the corresponding electrolytic cell 1041 by the anode and cathode cranes in each span of the workshop, and the produced residual electrodes can be directly returned to the lead melting pot 1072 through the residual electrode washing unit 1082 to be remelted into anode plates.

[0054] The electrolyzers 1041 in the electrolysis area 104 are arranged in a double-span workshop. The electrolyte circulation system 113 and the anode slime treatment system 114 are centrally configured at the rear side of the second-span workshop 102, which is convenient for centralized management and improves the working environment of the workshop. In the refined lead casting area 103, refined lead casting pots, a cathode rod extraction and washing unit 1061, and a lead ingot linear casting unit 1063 are arranged. The produced cathode lead is directly transported to the refined lead casting pot through the cathode rod extraction and washing unit 1061, melted, and then ingoted. There is no need for intermediate transfer, which ensures that the produced cathode lead is not contaminated and the product quality is guaranteed. Compared with the lead electrolysis workshop 100 in the related technology, this lead electrolysis workshop 100 simplifies the material transfer of each process, saves equipment and workshop investment, has a high degree of automation, a good working environment, and improves production efficiency and economic benefits.

[0055] The lead electrolysis workshop 100 according to the embodiment of the present invention has the advantages of clear functional zoning, less land occupation, effective avoidance of cross-operation between regions, good production environment, high degree of automation, and high production efficiency.
