Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead smelting technology, and in particular to an electrolyte distribution and adjustment device for a lead electrolytic washing tank. Background Technology
[0002] As the electrolysis cycle extends, the anode mud at the bottom of the electrolytic cell gradually increases, which in turn affects the yield and quality of precipitated lead. Therefore, the wet process workshop will carry out a washing operation after a certain period of electrolysis. Generally, it is washed once every 3-5 months. The more anode mud falls into the cell, the shorter the cycle is, and the less it falls into the cell, the longer the cycle is. The washing time is generally about 10 days.
[0003] Due to the unstable source of crude lead, the antimony content in crude lead tends to be low. During the electrolysis process, the anode mud is not properly attached to the plate and falls into the tank too much, resulting in large fluctuations in the composition of the electrolyte, which in turn affects the quality of the deposited lead. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an electrolyte distribution and adjustment device for lead electrolytic washing tanks, which aims to solve the problem of electrolyte composition fluctuation in electrolytic tanks in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electrolyte distribution and adjustment device for a lead electrolytic washing tank, comprising a base and an electrolytic tank, characterized in that: the electrolytic tanks are arranged side by side, a dispensing tank is fixed at the top of two adjacent electrolytic tanks, several dispensing pipes are arranged on both sides of the dispensing tank, the other end of the dispensing pipes is arranged at the upper part of the electrolytic tank, a main drain pipe is arranged at the lower end of the electrolytic tank, several branch pipes are arranged on the main drain pipe, the other end of the branch pipes is arranged at the lower part of the electrolytic tank and penetrates the electrolytic tank, a drain pump is also arranged on the main drain pipe, the other end of the main drain pipe is arranged at the upper part of the transfer tank, the transfer tank is installed on the upper part of the base, the transfer tank is divided into four sections of the same volume by a partition plate, a delivery pipe is arranged at one end of the transfer tank, a delivery pump is arranged on the delivery pipe, and the other end of the delivery pipe is arranged at the upper part of the dispensing tank.
[0006] As a further description of the above technical solution: The transfer tank is coated with an anti-corrosion paint layer inside, and reinforced with ribs on the outside. A sludge discharge pipe is installed at the bottom of the transfer tank, and a sludge discharge pump is installed at the top of the sludge discharge pipe.
[0007] As a further description of the above technical solution: The base is fixedly equipped with columns around its perimeter, with a canopy on top of the columns, and a cofferdam on the outside of the base.
[0008] As a further description of the above technical solution: The transfer trough measures 8.5 meters, 8 meters, and 1.5 meters, with two overflow outlets located in the middle of the transverse partition plate.
[0009] This utility model has the following beneficial effects: In this invention, the transfer tank is divided into four smaller tanks of the same volume and numbered accordingly. This allows the electrolyte transported from the electrolytic cell to the transfer tank to be stored separately. The content of each element in the electrolyte is measured and then adjusted. After adjustment, the electrolyte is transported back to the electrolytic cell. Attached Figure Description

Detailed Implementation
[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figure 1 — Figure 5This utility model provides an embodiment of an electrolyte distribution and adjustment device for a lead electrolytic washing tank, comprising a base 13 and an electrolytic tank 1. The electrolytic tanks 1 are arranged side-by-side, with a dispensing tank 4 fixed to the top of each adjacent electrolytic tank 1. Several dispensing pipes 12 are arranged on both sides of the dispensing tank 4, with the other end of each dispensing pipe 12 positioned above the electrolytic tank 1. A main drain pipe 3 is located at the lower end of the electrolytic tank 1, with several branch pipes 2 arranged on the main drain pipe 3. The other end of each branch pipe 2 is positioned below the electrolytic tank 1 and penetrates it. A drain pump 5 is also installed on the main drain pipe 3, with the other end of the main drain pipe 3 positioned above a transfer tank 6. The transfer tank 6 is mounted on the upper part of the base 13. Divided into four equal-volume sections by partition 18, the transfer tank 6 is equipped with a liquid delivery pipe 10 at one end, a liquid delivery pump 11 on the liquid delivery pipe 10, and the other end of the liquid delivery pipe 10 is located on the upper part of the liquid distribution tank 4. The interior of the transfer tank 6 is coated with an anti-corrosion paint layer 17, and the exterior of the transfer tank 6 is equipped with reinforcing ribs 7. The lower part of the transfer tank 6 is equipped with a sludge discharge pipe 8, and the upper part of the sludge discharge pipe 8 is equipped with a sludge discharge pump 9. The base 13 is fixedly equipped with columns 15 around its perimeter, and a canopy 16 is provided on the top of the columns 15. A dike 14 is provided on the outside of the base 13. The dimensions of the transfer tank 6 are 8.5 meters * 8 meters * 1.5 meters. Two overflow ports 19 are opened in the middle of the transverse partition 18 of the transfer tank 6.
[0013] During construction, the foundation 13 was poured first. The foundation has an area of 110 square meters and a load-bearing capacity of 110 tons. A transfer trough 6 was welded onto the foundation 13, and reinforcing ribs 7 were welded onto the exterior of the transfer trough 6 using channel steel. After the transfer trough 6 was completed, pipelines were laid and equipment was installed. The transfer trough 6, measuring 8.5 meters * 8 meters * 1.5 meters, was constructed on the foundation 13, divided into four equal sections: temporary storage tanks #1, #2, #3, and #4. Each tank has a capacity of 25 m³, for a total capacity of 100 m³, used to transfer the electrolyte used for daily tank washing.
[0014] The electrolyte from the daily washing of the electrolysis tanks in workshops #1 and #3, along with the anode mud, is pumped to temporary storage tank #2. After the electrolyte in temporary storage tank #2 is clarified, the supernatant is pumped to temporary storage tank #1. The electrolyte in temporary storage tank #1 is pumped to low-level tank #1 and returned to the electrolysis system. The anode mud at the bottom of temporary storage tank #2 is pumped to the anode mud cylinder and fed into the filter press.
[0015] Similarly, the electrolyte from the daily washing of the electrolysis tanks in workshops #2 and #4, along with the anode mud, is pumped to temporary storage tank #3. After the electrolyte in temporary storage tank #3 is clarified, the supernatant is pumped to temporary storage tank #4. The electrolyte in temporary storage tank #4 is pumped to low-level tank #2 and returned to the electrolysis system. The anode mud at the bottom of temporary storage tank #3 is pumped to the anode mud cylinder and fed into the filter press.
[0016] Meanwhile, in order to keep the electrolyte in the electrolysis system clean, filter racks are added above the No. 1 and No. 4 temporary storage tanks. The filter racks are lined with filter cotton to filter particulate impurities in the electrolyte. The electrolyte from the No. 1 and No. 2 low-level cells is pumped through the filter racks to the No. 1 and No. 4 temporary storage tanks respectively. The filtered electrolyte is then pumped to the No. 1 and No. 2 high-level cells and returned to the electrolysis system.
