Stirring, zinc metal sheet many kinds of measures processing, the finally obtained Spongy Cadmium increased quality such as are placed in the zinc metal sheet frame of trepanning and smoothly realize
Briquetting solves problem existing for traditional processing technology.
The purpose of this utility model is achieved through the following technical solutions：
A kind of zinc metal sheet displacement prepares the device of Spongy Cadmium, including multiple displacement slots 1 and lautertuns 10；It is set in first displacement slot
There are cadmium sulfate solution pipe 2 and sulfuric acid or zinc waste electrolyte pipe 4, cadmium sulfate solution pipe 2 to be equipped with spiral heat exchanger 3；End
Displacement slot is connect with lautertuns 10；Between displacement slot, between displacement slot and lautertuns by be arranged in displacement slot side wall upper part
Chute 9 connect；
Displacement slot 1 is circle, and groove body axis position is equipped with blender 7, multiple zinc metal sheet frames 5 are equipped in groove body, zinc metal sheet frame 5
Bottom and a side are separately fixed on the bottom and inner wall of groove body, and 5 opened top of zinc metal sheet frame facilitates placement zinc metal sheet, remaining
A large amount of circular holes 6, solution and displacement Spongy Cadmium free flow from circular hole obtained by the reaction are opened up on three sides；Groove body inner wall
It is additionally provided with deflector 8, bottom is equipped with blow valve 12；
Filter cloth natural filtration is placed in lautertuns 10,10 bottom of lautertuns connects delivery pump 11.
The quantity of displacement slot 1 is more than one.
Blender 7 installs one layer or more blade, reinforces solution mixing effect and replacing velocity, the Spongy Cadmium replaced are fast
Speed falls off from zinc metal sheet, into solution.
The above zinc metal sheet frame 5 there are three being set in each displacement slot 1.
Displacement slot 1, chute 9 and lautertuns 10 are stainless steel or glass steel material.
The course of work：The utility model forms multi-level permutation by being connected in series with multiple displacement slots 1；Cadmium sulfate solution
It is added in first displacement slot after spiral heat exchanger is heated to 40 ~ 70 DEG C, while sulfuric acid or zinc waste electrolyte pass through sulphur
Acid or zinc waste electrolyte pipe 4 are also added in first displacement slot, for controlling pH value of solution=2 ~ 4 in displacement slot；Cadmium sulfate solution with put
The zinc metal sheet set in zinc metal sheet frame 5 is replaced, and Spongy Cadmium is generated；Spongy Cadmium is flowed into cadmium sulfate solution by chute 9 next
Displacement slot by natural filtration, obtains Spongy Cadmium product, filtering trench bottom is until finally flowing into lautertuns 10 on filter cloth
Liquid after displacement cadmium is delivered to the zinc in zinc production system recycling solution by delivery pump 11.
The beneficial effects of the utility model：1, by taking heat temperature raising plus acid for adjusting pH value and reinforcement stirring etc. special
Design, cadmium sulfate solution is by series multistage displacement reaction, and reaction speed is very fast, efficient, and the solution after displacement is low containing cadmium；2、
Zinc metal sheet is placed in the zinc metal sheet frame of trepanning, and under the action of double-layer paddle strong mixing, the Spongy Cadmium replaced is mixed with solution
Together, it sequentially flows in natural filtration slot, solution surface oxidation by air will not be swum in, need not also be beaten in reactive tank
Drag for Spongy Cadmium；3, zinc metal sheet reaction is thorough, does not have residual pieces and falls into slot bottom, briquetting effect and product quality are obviously improved.
