Description

The primary displacement of zinc powder prepares Spongy Cadmium device
Technical field
The utility model is that a kind of primary displacement of zinc powder prepares Spongy Cadmium device, belongs to the zinc abstraction technology neck of metallurgy industry Domain.
Background technology
In conventional wet zinc metallurgy production, the neutral sulphates cadmium solution that copper-cadmium slag leaches, some smelteries, which use, to be added Zinc powder room temperature is replaced twice, and Spongy Cadmium is obtained by filtration twice.This technique has the following problems:It need to replace twice, technological process Long, equipment is more, complicated for operation;Under normal atmosphere temperature neutral, replacement reaction speed is slow, and the zinc oxide indissoluble of zinc powder surface package Solution, seriously affects zinc powder utilization rate, zinc consumption amount is larger, and reaction is not thorough, and influences Spongy Cadmium briquetting effect and product quality.
Invention content
The utility model is in view of the above-mentioned problems, propose that a kind of primary displacement of zinc powder prepares Spongy Cadmium device, which can The oxidation film on displacement zinc powder surface is effectively eliminated, reaction speed is improved, Spongy Cadmium quality is improved, avoids the problem of briquetting difficulty.
The new novel purpose of this practicality is realized by following means:
A kind of primary displacement of zinc powder prepares Spongy Cadmium device, its once displacement slot, zinc powder slurrying tank, blender one and sulphur Sour cadmium solution pipe, it is characterised in that zinc powder slurrying tank, cadmium sulfate solution pipe and blender one, stirring are housed at the top of a displacement slot The agitating shaft of device one stretches into a displacement slot and has three layers of stirring blade, and the sulphur of control ph values is further connected at the top of a displacement slot Acid tube.
The cadmium sulfate solution pipe is connect with spiral heat exchanger, to heat cadmium sulfate solution in advance.
The middle and upper part of displacement slot is that cylindrical lower part is handstand truncated cone-shaped, and there is bleeder valve at platform bottom.
There is natural filtration slot below the bleeder valve, there is filter cloth, trench bottom to have delivery pump in natural filtration slot, so as to by mistake Liquid pump is sent to zinc electrolysis operation after filter.
The lowest level of three layers of stirring blade is vanelets, in handstand round platform.
Displacement slot top seal is simultaneously connected to the exhaust fan being connected to a displacement slot, exhaust fan outlet and acid mist purifying Tower connects, the toxic and harmful gas generated so as to timely processing replacement process.
There are blender two, water pipe and zincification powder mouth in the zinc powder slurrying tank.
The course of work of the utility model is as follows:
Cadmium sulfate solution is put into a displacement slot after spiral heat exchanger is heated to 40 ~ 60 DEG C;Pass through sulfuric acid pipe Sulfuric acid is added, pH value of solution=2.5 ~ 4 in displacement slot are controlled;After zinc powder adds water to stir pulp in zinc powder slurrying tank, it is added primary It is reacted into line replacement in displacement slot, starts blender one and reinforce stirring, promote fully reaction.What is generated in replacement process various has Malicious pernicious gas pumps to acid mist purifying tower purified treatment through exhaust fan.
After zinc dust precipitation cadmium reaction, opens bleeder valve and solution is put into natural filtration slot, placed in lautertuns Filter cloth natural filtration obtains Spongy Cadmium product on filter cloth, and filtering trench bottom is displaced liquid, and zinc production system is delivered to through delivery pump Zinc in system recycling solution.
The utility model is characterized in that:By take heat temperature raising, plus acid for adjusting pH value, three layers of stirring blade strong mixing, Rounding bench-type displacement slot, the configuration designs such as exhaust fan and acid mist purifying tower, cadmium sulfate solution need to only be added the zinc powder of theoretical amount into The primary displacement of row, reaction speed is fast, efficient, and displacement reaction is thorough, and the solution after displacement is practically free of cadmium, not will produce metal Spongy Cadmium bulk agglomeration, not plugging during tapping, briquetting effect and product quality are obviously improved.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In Fig. 1, the label of each parts is as follows:
Displacement slot of 1-;2- cadmium sulfate solution pipes;3- spiral heat exchangers;4- sulfuric acid pipes;5- zinc powder slurrying tanks;6- Blender one;7- zincification powder mouths;8- blenders two;9- water pipes;10- exhaust fans;11- bleeder valves;12- natural filtration slots;13- is defeated Send pump;14- acid mist purifying towers.
Specific implementation mode
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, a displacement slot 1 is approximate with common agitator, cylindrical shape is in middle and upper part or cries cylinder, lower part For reverse frustoconic or inversed taper platform shape.It makes reverse frustoconic and the discharge of materials in slot is conducive to fall in lower part.It is set below inverted round stage Bleeder valve 11.The materials such as the top steel plate of displacement slot are closed, in order to avoid toxic and harmful gas escapes, zinc powder is installed in groove top portion Slurrying tank 5, blender 1 and exhaust fan 10, while sulfuric acid pipe 4 and cadmium sulfate solution pipe 2 being accessed in a displacement slot.
A zinc powder slurrying tank actually small agitator, the middle blender of 28 structure of blender and a displacement slot therein One is identical, is all that a motor drives agitating shaft rotation, stirring blade is installed additional on agitating shaft.Zincification powder mouth 7 and water pipe 9 are normal Rule design.There is gate valve control between zinc powder slurrying tank and a displacement slot.
As described above, being equipped with three layers of stirring blade on the agitating shaft of blender one, upper two layers is big blade, positioned at once setting Slot middle and upper part is changed, lowest level is vanelets, is located in inverted round stage, and design in this way can be sufficiently stirred material, not stay dead angle, is allowed anti- Material is answered to come into full contact with, this is that the utility model ensures displacement thoroughly one of crucial setting.
Exhaust fan pipeline, displacement slot of preceding company lead to acid mist purifying tower 14 afterwards.Cadmium sulfate solution pipe is changed with spiral plate type Hot device 3 is connected to, to place into a displacement slot after cadmium sulfate solution is first heated to 40-60 DEG C.This temperature condition can carry The reaction speed of height displacement, improves production efficiency.
Control gate valve on sulfuric acid pipe and cadmium sulfate solution pipe is traditional gate valves.
Natural filtration slot 12 can be a pond or a bulk container, and filter cloth is placed in centre, after replacement completion Solution is put into wherein, and by filter-cloth filtering, Spongy Cadmium stays on filter cloth, and filtrate flows to slot bottom accumulation, is periodically pumped into conveying Zinc is recycled in zinc electrolysis operation.
Unmentioned parts and label are as described above.
Make model machine through applicant's system of unit to try out, the primary displacement of this zinc powder of the utility model prepares Spongy Cadmium device Reaction speed is fast, efficient, and displacement reaction is thorough, and the solution after displacement is practically free of cadmium, not will produce metal sponge cadmium bulk Agglomeration, not plugging during tapping, briquetting effect and product quality are obviously improved.
