Description
Technical field
A kind of device for accelerating copper powder dissolution velocity in the anode mud of copper electroplating is the utility model is related to, belongs to non-ferrous metal smelting
Refine technical field.
Background technology
Traditional Method electrolysis production process output relative to anode weight about 0.5%-1.5% the earth of positive pole, except containing in the earth of positive pole
There is outside noble metal the also copper powder containing 15%-30%.It is unfavorable for the life of copper and noble metal in the earth of positive pole containing substantial amounts of copper powder
Production and technical-economic index, and common processing method is exactly that large quantity of air is continuously passed through into the electrolyte containing the earth of positive pole,
Copper, acid, the simultaneous state of oxygen are formed on the surface that solution and copper powder contact, in the case of acid and oxygen are simultaneous
The oxidisability higher than copper electrode potential is formed, oxidization of copper powder is entered solution into divalent ion.Air is passed through into solution at present
Method be that breather line is passed directly in the electrolyte containing the earth of positive pole, although air can be largely passed through, be passed through
Air forms big bubble rapid spilling liquid level again, and the solid, liquid, gas contact area formed in the solution is small, the time is short, oxygen
It can not be substantially dissolved in solution and play a role, dissolve that the efficiency of copper powder is low, by required in the earth of positive pole 80% copper powder dissolving
Time be at least 72 hours, do not accomplish the target of copper powder in the quick dissolving earth of positive pole in practical application, copper powder contains in the earth of positive pole
Measure less than being greatly lowered.
Utility model content
The purpose of this utility model in provide it is a kind of accelerate the anode mud of copper electroplating in copper powder dissolution velocity device, with solution
Certainly in the anode mud of copper electroplating copper powder dissolution velocity compared with the problem of slow, efficiency is low.
In order to solve problem above, the technical solution of the utility model is：One kind accelerates copper powder dissolution velocity in the earth of positive pole
Device, structure includes melt pit, stretches in melt pit and enter flow tube and air inlet pipe, enter below flow tube and be fixed with cone-shaped hood, influent stream
The port of export of pipe stretches to the inner chamber of cone-shaped hood, and the port of export of air inlet pipe is located in cone-shaped hood, set on the port of export of air inlet pipe
There is bubbler.
In order to further realize the utility model, cone-shaped hood opening angle is 25-45 degree.
In order to further realize the utility model, it is 5-50mm to enter length of the flow tube in cone-shaped hood.
In order to further realize the utility model, the spacing for entering the flow tube port of export and bubbler is 50-500mm.
The beneficial effects of the utility model are as follows：The utility model is additionally arranged cone-shaped hood in influent stream pipe end, passes through control
Fluid velocity produces condition of negative pressure, and bubbler is additionally arranged in air inlet pipe end, and air forms a large amount of minute bubbles after entering, with containing
The electrolyte of copper anode mud is thoroughly mixed to form foam.Utilize the contact area for increasing gas, liquid, solid three-phase so that in contact surface
The principle that the reaction of upper generation is accelerated, the oxidation dissolution speed of copper powder in the earth of positive pole is effectively improved, in activity duration and operation
The copper powder content in the earth of positive pole is greatly reduced in the case that journey is constant.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is Fig. 1 top view.
Reference is as follows：1st, flow tube is entered；2nd, air inlet pipe；3rd, cone-shaped hood；4th, bubbler；5th, melt pit；6th, air inlet pipe goes out
Mouth end；7th, the port of export of flow tube is entered.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1-2, a kind of device for accelerating copper powder dissolution velocity in the anode mud of copper electroplating, structure include melt pit 5, stretched
Enter and enter flow tube 1 and air inlet pipe 2 to melt pit 5, it is described enter the lower section of flow tube 1 be fixed with cone-shaped hood 3, the port of export 7 for entering flow tube 1 is stretched
Enter to the inner chamber of cone-shaped hood 3, the port of export 6 of the air inlet pipe 2 and be located in cone-shaped hood 3, set on the port of export 6 of the air inlet pipe 2
It is equipped with bubbler 4.
In the present embodiment, limit into the outlet 7 of flow tube 1 and stretch to the length H of the inner chamber of cone-shaped hood 3 as 5-50mm, cone-shaped hood 3
Opening angle A is 25-45 degree, and bubbler 4 and the spacing L for entering flow tube outlet 7 are 50-500mm.
In operation, by the electrolyte containing copper anode mud from enter in flow tube 1 with more than or equal to 2m/s speed inject, from influent stream
The outflow of pipe outlet 7, negative pressure is produced in the whole region of cone-shaped hood 3, air imports from air inlet pipe 2, with minute bubbles from bubbler 4
Form flows out, and the electrolyte under negative pressure state containing copper anode mud combines to form a large amount of uniform foam-like mixtures with air.
Because the contact area of solid, liquid, gas three-phase increases, the reaction occurred on the contact surface is accelerated because of the increase of contact area, from
And improve the oxidation dissolution speed of copper powder in the earth of positive pole.Anode is greatly reduced in the case where activity duration and operation process are constant
Copper powder content in mud.Experiment shows that every batch of earth of positive pole passes through the processing of 24 hours, and cupric can be down to less than 5%, have good
Good economic benefit.
