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
