Description

Electrodeposition tank

Technical Field

The utility model relates to the technical field of metal electrolysis, in particular to an electrodeposition tank.

Background

In the treatment process of the waste liquid generated in the copper electrolysis production, elements such as copper, nickel and the like in the waste liquid containing copper are usually recovered by an electrodeposition process. During the copper electrowinning process, the anodic reaction process generates a large amount of oxygen which can carry a large amount of acid mist when escaping from the electrowinning cell. A large amount of acid mist is diffused in an electrodeposition workshop, so that the acid mist has strong corrosion effect on a workshop and equipment of the electrodeposition workshop, and can cause severe operating environment of the electrodeposition workshop and seriously damage the physical health of operating personnel. The treatment method commonly used in the prior art is that a sealing cover is covered on an electrodeposition tank and used for collecting acid mist in a closed space enclosed by the electrodeposition tank and the sealing cover, so that the acid mist and gas are prevented from diffusing into a factory building, but the concentration of the acid mist in the electrodeposition tank is high, the reaction process of electrodeposition reaction is hindered, and the forming time of subsequent electrodeposited copper is influenced. Therefore among the prior art, outside extension has the boss of induced drafting on the cell body of an electrodeposition tank side, the last mesa of the boss of induced drafting arranges with the last notch parallel and level of electrodeposition tank body, it links to each other with updraft ventilator to set up the hole of induced drafting on the boss of induced drafting, in time take away the acid mist in the electrodeposition tank, ensure the reaction mass of electrodeposition reaction, but in this kind of structure, the last mesa of the boss of induced drafting and the last notch parallel and level of electrodeposition tank body, be in a plane, a large amount of acid mist that produces in the production process, steam adsorbs on sealed the cover, flow down to the electrodeposition tank body on, can cause following harmful effects: firstly, a large amount of copper sulfate-containing water vapor overflows from the joint of the sealing cover and the air suction hole, so that the field operation environment is influenced, and the factory building is corroded; secondly, the copper sulfate-containing liquid flows back into the adsorption pipeline, the pipeline is blocked after crystallization, and acid mist cannot be pumped out in time.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an electrodeposition tank which can collect overflowed water mist and reduce pipeline blockage.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides an electrodeposition tank, outwards extend on one side cell body of electrodeposition tank body has the boss that induced drafts, set up the hole of induced drafting that links to each other with the pipeline that induced drafts on the boss that induced drafts, the last mesa of the boss that induced drafts raise gradually to the outside by the inboard and arrange, the boss inboard that induced drafts links up the height of mesa and the last notch height of electrodeposition tank body in position department with the electrodeposition tank body.

In the scheme, the air suction boss is designed to form a certain angle, so that the acid liquid moves towards the inside of the electrodeposition tank, the problem that copper sulfate solution overflows from the air suction hole of the electrodeposition tank is solved, the field environment is effectively improved, and the structure is protected.

Detailed Description

As shown in figure 1 and figure 2, the electrodeposition tank is characterized in that an air suction boss 20 is outwards extended from a tank body on one side of an electrodeposition tank body 10, an air suction hole 21 connected with an air suction pipeline 30 is formed in the air suction boss 20, the upper table top of the air suction boss 20 is gradually raised from the inner side to the outer side, and the height of the upper table top at the joint position of the inner side of the air suction boss 20 and the electrodeposition tank body 10 is equal to the height of the upper groove opening of the electrodeposition tank body 10. The air suction boss 20 is designed to be at a certain angle, so that the acid liquid moves towards the inside of the electrodeposition tank, the problem that the copper sulfate solution overflows from the air suction hole 21 of the electrodeposition tank is solved, the field environment is effectively improved, and the structure is protected.

As the preferred scheme of the utility model, the upper notch of the electro-deposition tank body 10 is positioned in the horizontal plane, the included angle between the upper table surface of the air suction boss 20 and the horizontal plane is alpha, and alpha is more than 0 and less than 45 degrees.

Through many times of experiments, when the included angle alpha is 30 degrees, the cooperation with the upper sealing cover is not influenced, and the backflow of the acid liquor can be ensured.

The hole 21 that induced drafts arranges along the vertical direction on the boss 20 that induced drafts, and induced draft pipeline 30 inserts induced draft hole 21 and constitutes sealed cooperation from the below in the hole 21 that induced drafts, and the last mesa that induced drafts boss 20 is higher than to the last mouth of pipe 31 of induced draft pipeline 30, forms approximate 3 cm's difference in height, and the acidizing fluid of the last mesa of the boss 20 that induced drafts can't get into induced draft pipeline 30 in, just can not block up the pipeline yet.

The outer edge of the air suction boss 20 is surrounded by a liquid baffle plate 22 to prevent acid liquid from leaking, improve the field environment and protect the structure.
