Abstract
Description
Technical Field
[0001] The utility model relates to a novel black copper mud receiving trough, belonging to the technical field of copper electrolytic refining. Background Art
[0002] During the copper electrolytic refining process, the composition of the electrolyte is constantly changing, the copper ion concentration is constantly rising, and impurities are constantly accumulating. In order to maintain the copper, acid concentration and impurity concentration in the electrolyte within the specified range, the electrolyte must be purified and adjusted to remove excess copper and impurities to keep the electrolytic process going normally.
[0003] Induced arsenic removal belongs to the electrolytic solution purification process, which is realized by using the electrolytic cell as a unit. In each electrolytic cell, cathodes and anodes are arranged alternately. The cathode is a residual plate, and the anode is an insoluble lead anode plate. After the electrolyte is poured in, direct current is passed for production. Black copper mud is precipitated on the cathode, i.e. the residual plate, and most of the black copper mud settles to the bottom of the electrolytic cell. The main chemical elements of the black copper mud are copper, arsenic and other compounds.
[0004] The depth of the electrolytic tank is about 1.7m, and the concentration of sulfuric acid in the electrolyte is about 250mg / l. The traditional method is for the operator to jump to the bottom of the electrolytic tank and use a shovel to load a ton bag to clean the black copper mud. This working method has the following disadvantages:
[0005] 1. The temperature at the bottom of the tank is high, the acid mist is large, and the depth of the black copper mud at the bottom of the tank is 15 to 20 cm. The workers jump to the bottom of the tank to clean the black copper mud, which is labor-intensive and may cause sprained ankles, heat stroke, etc.
[0006] 2. There is a certain amount of lift loss when using a shovel for cleaning;
[0007] 3. Black copper mud is an internal transfer material, and the one-time use cost of a ton bag is relatively high, with a unit price of about 60 yuan;
[0008] 4. Personnel enter the bottom of the tank to clean the black copper mud, and the loading and unloading operation speed is slow. It takes 30 to 40 minutes to clean the black copper mud in each tank, which delays the power supply time and has low tank utilization. Utility Model Content
[0009] In order to overcome the shortcomings of the prior art, the utility model provides a novel black copper mud receiving trough. Use of the device can effectively increase the trough cleaning time, improve work efficiency, reduce labor intensity and increase the safety factor, and avoid black copper mud head loss.
[0010] The utility model adopts the following technical scheme to solve the technical problems: a novel black copper mud receiving trough comprises a stainless steel square steel frame, a stainless steel lifting lug and a glass fiber reinforced plastic trough body, wherein the glass fiber reinforced plastic trough body is a rectangular trough body, a circle of stainless steel square steel frame is fixed around the top of the glass fiber reinforced plastic trough body, four single pieces of the stainless steel square steel frame are arranged outwardly in an inclined manner, and the four single pieces of the stainless steel square steel frame are inlaid with glass fiber reinforced plastic; a stainless steel lifting lug is fixed at the four corners of the glass fiber reinforced plastic trough body on the inner side of the stainless steel square steel frame, the four stainless steel lifting lugs are arranged in a rectangular shape on the glass fiber reinforced plastic trough body, and the stainless steel lifting lugs are provided with lifting rings; the outside of the stainless steel square steel frame is pasted with glass fiber reinforced plastic, the outside of the stainless steel lifting lug is pasted with glass fiber reinforced plastic, the stainless steel square steel frame is made of stainless steel square steel, and the inside of the glass fiber reinforced plastic is flat and smooth.
[0011] The beneficial effects of the utility model are as follows: compared with the existing method for cleaning the black copper mud at the bottom of the tank, the black copper mud receiving trough of the utility model can be unloaded by using a crane, the black copper mud receiving trough is placed closely at the bottom of the electrolytic deposition tank and avoids large and small blockages, so as to avoid leakage of the electrolytic deposition tank caused by scratches and large and small blockages, the black copper mud receiving trough can be recycled, and the economic cost is reduced. Two black copper mud receiving troughs are placed in each electrolytic deposition tank, which can save 25 minutes to 30 minutes of tank cleaning time, save manpower and material resources, greatly improve the utilization rate of the tank, reduce the labor intensity of personnel, and increase the safety factor.

The center spacing of adjacent single-slot black copper mud receiving troughs is equal to the center spacing of adjacent electrolytic deposition tanks; the black copper mud receiving trough is placed at the bottom of the electrolytic deposition tank. During the induced arsenic removal and unloading operation, the operator does not need to jump to the bottom of the tank to use a shovel and a ton bag to clean and collect the black copper powder. The operator uses a crane to lift the black copper mud receiving trough on the black copper mud receiving trough and dump the black copper mud in the trough to the unloading port to complete the tank cleaning work. This working method is efficient, and the staff no longer needs to work at the bottom of the electrolytic deposition tank, which improves safety and avoids the loss of lift.
