Description
Technical field
The present invention relates to a kind of mechanical agitation type in-pulp electrolysis groove, be especially suitable for being electrolysed ore pulp and use.
Background technology
Electrolysis bath is the key equipment supporting the electrolytic etching of metal industry such as lead, zinc, manganese, aluminum, but, existing electrolysis bath mostly can only electrolytic solution, and ore pulp can not be electrolysed, namely must first be prepared as electrolyte before electrolysis and just can be electrolysed.
Breeze is prepared as electrolyte and needs through multiple steps such as chemical combination, dissolving, filter pressing and remove impurity, the many costs of step are high, preparation process there is also certain loss, if breeze can be directly prepared in electrolysis bath ore pulp to be electrolysed, just can significantly Simplified flowsheet, cut down the number of intermediate links, cost-effective and improve product yield.
In-pulp electrolysis essence is exactly to add breeze and corresponding acid in electrolysis bath, directly carry out breeze and carry out electrolysis procedure after the combination reaction of acid, namely chemical combination is carried out with electrolysis simultaneously, the advantage of this operation is can significantly Simplified flowsheet, chemical combination, remove impurity, electrolysis is made jointly to complete in groove, omit the operations such as filter pressing, also a lot of reservoirs can be reduced while cost-effective, the acid that electrolytic anode produces simultaneously constantly can be reacted with breeze, the metal in breeze is made the most constantly to dissolve, it is thus achieved that higher electrolytic yield.
Breeze can settle in electrolysis bath, present in actual electrolytic process, greatest difficulty is exactly that ore pulp suspends, if ore pulp can not realize preferably suspending, the acid being then electrolysed generation cannot well be reacted with breeze, make what breeze dissolved to slow, in electrolysis bath, concentration of metal ions also is difficult to improve, and makes electrolysis not to be smoothed out.If electrolysis can not be carried out smoothly, then the acid being electrolysed generation can be less, and the speed that breeze dissolves can be slower, causes vicious cycle, finally makes electrolysis work paralyse.
Realize ore pulp to suspend, modal means are stirrings, but common mechanical type stirring is only less at stirring paddle, ore pulp just can be made preferably to suspend in the case of stirring faster, but energy consumption can be the highest in such agitating device operation process, and large-scale electrolysis bath needs multiple agitating devices could realize the normal operation of electrolysis, and cannot realize electrolysis bath is swept end effect simultaneously and the mineral powder granular that can not suspend is carried out the process of serialization thus be allowed to suspend, thus prior art can not meet the requirement of in-pulp electrolysis.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, there is provided a kind of simple in construction, energy consumption is low, ore pulp can be made preferably to suspend, and can realize that electrolysis bath is swept end function and the mineral powder granular that can not suspend carries out the process of serialization thus be allowed to the mechanical agitation type in-pulp electrolysis groove of suspension.
For overcoming the deficiencies in the prior art, the present invention takes techniques below scheme:
A kind of mechanical agitation type in-pulp electrolysis groove, including positive pole copper bar, positive plate, negative pole copper bar, minus plate and electrolyte membrane, it is characterised in that: pole plate and both positive and negative polarity copper bar all use V-type to overlap；The middle and lower part of electrolysis bath is provided with the major axis stirring paddle of lateral arrangement；The bottom of electrolysis bath is provided with the auger conveyor of lateral arrangement, and the conveying termination of auger conveyor is provided with cone bottom structure, and the cone end connects wet method flour mill through discharge nozzle, and wet method flour mill connects electrolysis bath through conveying pipe.
Mechanical agitation type in-pulp electrolysis groove typically uses the anti-corrosion material of resistance to certain high temperature to make, pole plate coordinates employing V-type overlap joint with both positive and negative polarity copper bar, easy and simple to handle being also easy to ensures more accurate spacing between pole plate, and V-type overlapping mode, anode and cathode copper bar V-type opening can produce auto lock clamping action to pole plate copper bar, make that conductive contact is very reliable, contact resistance is the least, completely avoid pole plate and anode and cathode copper bar commonly to overlap the loose contact of existence and make heating serious, and electric current impacted after directly affect electrolytic efficiency.
Assembling made by electrolyte membrane suitable thickness filter cloth, plays isolation and produces cathode chamber effect but can intercept slag and energising can realize electrolysis, and when namely electrolyte membrane and electrolysis electric field realize being electrolysed, the isolation obstruct slag of the anode chamber and the cathode chamber, but can allow cation pass through.
Electrolyte membrane chamber composition cathode chamber remainder is all anode chamber, anode chamber's Inner electrolysis constantly produces acid, it is breeze and the mixture of acid in anode chamber, anode electrolysis produces acid and can constantly react with breeze, barrier film isolates cathode chamber and stops that slag enters, and metal ion realizes electrolysis in clean cathode chamber and separates out.
Large scale electrolytic cell typically grows about six meters, ore pulp suspension is the biggest obstacle hindering the application of in-pulp electrolysis technology, suspend for realizing stirring ore pulp, the design uses major axis stirring paddle low speed rotation, sweep with low speed distance large area and more make ore pulp stablize low energy consumption maintenance suspension, auger conveyor realizes orientation conveying to larger particles and the sedimentation breeze that cannot suspend, realized concentrating output by left end cone bucket, wet method flour mill is entered by discharge nozzle, wet method flour mill band impeller has conveying function, coarse granule realizes reflux cycle by conveying pipe again through flour mill dispersion and fining, flour mill can carry out Tong Bu the most discontinuously startup with auger conveyor, to reduce the high energy consumption and equipment attrition continuously run.
Compared with prior art, beneficial effects of the present invention also resides in:
System structure is the most reasonable, convenient to carry out, and pole plate overlaps with both positive and negative polarity V-arrangement, it is simple to realizing the accurate spacing of pole plate, this overlapping mode also has self-locking clamping character, it is ensured that reliable contacts, it is achieved most preferably conduct electricity；Low speed long blade large area is swept and is more particularly suitable for long-time, the maintenance ore pulp suspension of low energy consumption；Flour mill carries out Tong Bu the most discontinuously startup with auger conveyor, can reduce the high energy consumption and equipment attrition continuously run；Both of which has been implemented in combination with reliable suspension and the electrolysis of ore pulp, and coarse granule carries out separating twice can promote to improve electrolytic metal productivity, is especially suitable for big production and application, has a extensive future.
