Background technology
In the Zinc hydrometallurgy process, the solution of zinc sulfate that plumbous zinc ore leaches gained is sent into and is carried out electrolysis in the electrolyzer, in this process, sedimentary detrimental impurity must reduce as far as possible in the solution of zinc sulfate, arsenic salt purification and impurity removal technology is impurity removal process commonly used, and this technology generally is divided into three phases: promptly first section copper removal chlorine, two sections remove cobalt nickel, three sections and remove cadmium.Wherein removing cadmium is to carry out continuously in the system that placed in-line 4-5 boiling purification tank formed, be the fluid-tight state in the boiling purification tank system, the solution of zinc sulfate that last boiling purification tank comes out separates through hydrocyclone, the clear liquid overflow on upper strata is the solution of zinc sulfate after purifying, carry out further carrying out following process after the liquid-solid separation, the hydrocyclone underflow need return into the boiling purification tank again and remove the cadmium processing, generally be to be back to first boiling purification tank to handle, so circulation is carried out.Because air has very strong oxygenizement, can make except that cadmium in the slag of cadmium gained redissolves as entrained air in the system and to enter in the solution of zinc sulfate, answer strictness to prevent the inclusion of air system, and in boiling purification tank system, add the easiest entrained air in the operating process of zinc powder and hydrocyclone underflow retrieval system.Because in the prior art, zinc powder adding mode is that per tour adds once, each 2 t-3t, zinc powder joins after the cadmium solution of zinc sulfate mixes bottom the purification tank that seethes with excitement from last boiling purification tank top with removing so that solid form is disposable, the swirler underflow also is the top adding from the boiling purification tank, and this feed way of swirler underflow and zinc powder is difficult to accomplish airtight reinforced, unavoidably causes the inclusion of air system, and the feeding device of existing boiling purification tank and method need further to improve therefore.
The utility model content
The purpose of this utility model is to provide a kind of feeding device that removes cadmium boiling purification tank system, it can prevent entrained air when feeding in raw material except that cadmium boiling purification tank, avoid entering in the solution of zinc sulfate because of sneaking into of air redissolved the cadmium that purifies in the slag of back, cause detrimentally affect to subsequent handling, and have simple in structure, easy to operate advantage.
The purpose of this utility model is to provide a kind of charging process that removes cadmium boiling purification tank system, it adopts said apparatus to implement, can prevent entrained air when feeding in raw material except that cadmium boiling purification tank, avoid entering in the solution of zinc sulfate, cause detrimentally affect to subsequent handling because of sneaking into of air redissolved the cadmium that purifies in the slag of back.
The technical solution of the utility model is:
A kind of feeding device that removes cadmium boiling purification tank system, it is applied to comprise the placed in-line cadmium boiling purification tank system that removes that removes cadmium boiling purification tank and hydrocyclone more than two, remove cadmium boiling purification tank system feeding device and comprise that stacked vertically inner chamber communicates and the zinc powder pulp device of airtight connection, the fluid-tight device, the zinc powder serous fluid distributor, described fluid-tight device is provided with the overflow venting port, fluid-tight device bottom and hydrocyclone underflow pipeline UNICOM, described zinc powder serous fluid distributor be provided with system in respectively remove the zinc powder slurries outlet pipe that cadmium boiling purification tank is complementary and connects.
As to further improvement of the utility model, described zinc powder pulp device top be opening up mouthful, the bottom is a cylinder, the overflow port that described zinc powder pulp device side is provided with zinc powder pulp solution line and hydrocyclone links.
As to further improvement of the utility model, described fluid-tight device top is round shape, and the bottom is conical.
As to further improvement of the utility model, described overflow venting port is connected with weir tank outward.
As to further improvement of the utility model, the quantity of the zinc powder slurries relief outlet of described zinc powder serous fluid distributor is 5 with the quantity of removing cadmium boiling purification tank.
The utility model is work like this:
Zinc powder adds in the zinc powder pulp device from the zinc powder storehouse, the solution of zinc sulfate that adds the hydrocyclone overflow simultaneously, with zinc powder mixing pulp, the zinc powder slurries enter in the cylinder, air in the zinc powder slurries is discharged from the overflow port that cylinder is provided with, the less zinc powder of particle diameter also can be discharged from overflow port simultaneously, and the zinc powder slurries that not aeriferous granularity is fit to enter pulp zinc powder serous fluid distributor through the circular cone bucket, enters system by the pipeline custody transfer to respectively removing cadmium boiling purification tank bottom.
The beneficial effects of the utility model are:
The utility model is by improving the zinc powder feed way, promptly directly being improved to the form that is slurried into slurries from the mode of removing the top adding of cadmium boiling purification tank by solid zinc powder of the prior art adds, thereby realized the airtight reinforced of zinc powder, stopped the possibility of entrained air, simultaneously also make zinc powder have good mobility, it is fast to add inbound traffics, good uniformity.Utilize the part overflow pulp zinc powder of swirler, realized the cyclic balance of material in the system.The zinc powder that pulp is good further mixes with the swirler underflow that need join equally except that in the cadmium boiling purification tank system, and the concentration of zinc powder slurries is further diluted, and its flowability is further improved.The zinc powder serous fluid distributor is directly linked with respectively removing cadmium boiling purification tank bottom by pipeline, and the zinc powder slurries can be delivered under air-tight state except that cadmium boiling purification tank system.The utility model can prevent entrained air when feeding in raw material except that cadmium boiling purification tank, avoids entering in the solution of zinc sulfate because of sneaking into of air makes the cadmium redissolution that purifies in the slag of back, causes detrimentally affect to subsequent handling, and has simple in structure, easy to operate advantage.
