The both sides distribution block 16-2, and collapsed again by two level wedge-shaped opening 16-3, completion is once mixed and stirred.
Calcium superphosphate after once mixing and stirring collapses outflow by the osculum end of two level wedge-shaped opening 16-3, flows into material scattering device 17, by
Gap between 1 surface of bottom surface and belt conveyor of material scattering device 17 is flowed through, which is laid in belt conveyor 1 by calcium superphosphate dispersion
Secondary mix and stir is completed on surface.
It is secondary mix and stir after calcium superphosphate flow through be dislocatedly distributed mix and stir pipe 18, under the mixing and stirring for mixing and stirring pipe 18 complete three times
It mixes and stirs.
Calcium superphosphate after mixing and stirring three times is flowed through is laid in 1 table of belt conveyor by material-homogenating device 19 by acidproof rubber
Face collapses transfer out belt conveyor 1 later again.
In practice, it has been found that if the calcium superphosphate after reaction is stirred using conventional mixing plant, can make entire production
Object stirs into paste, can not form finished product；In order to solve this problem, it is devised in hood 2 a series of for mixing and stirring of mixing and stirring
Structure (is provided with fixed blunger 16, material scattering device 17, mixes and stirs pipe 18 and material-homogenating device 19), this mixes and stirs structure to belt conveyor
When calcium superphosphate on 1 is mixed and stirred, gravity will not be carried out to calcium superphosphate and beaten, and then avoided calcium superphosphate and mixed paste
Shape.
Pad 20 is equipped between 2 bottom of hood and 1 surface of belt conveyor above-mentioned.Pad 20 is set, can ensured
While sealing, reduce the friction between 2 bottom of hood and 1 surface of belt conveyor.Pad 20 can be soft rubber cushion, can also be
The cushion that the materials such as nylon make.
Partition wall 21 is staggeredly distributed in fluorine removal pond 4 above-mentioned, the top in fluorine removal pond 4 is additionally provided with sprayer II 22.Setting is handed over
The partition wall 21 of mistake distribution makes the flow in fluorine removal pond 4 increase flowing stroke, and then increases mixing the time for water and four fluorine gas, carries
Rise the absorptivity of four fluorine gas.Sprayer II 22 is set, the absorptivity of four fluorine gas can be further promoted.
The course of work of fluorine removal reforming unit：Calcium monohydrogen phosphate and stone of once the cure, grain size no more than 5mm will be had been subjected to
Grey phosphorus slag (hereinafter referred to as semi-finished product) is inputted by belt conveyor 1 (speed of belt conveyor 1 is 25~30cm/s) feed end, conveying
Belt 1 conveys semi-finished product, and before semi-finished product enter the reaction of hood 2, a bar ditch are left in surface of semi-finished by sawtooth 15
Slot, into after hood 2, the mixed liquor that sulfuric acid, water and the raising agent in liquid mixing box 6 react is sprayed at semi-finished product by solvent jet pipe 5
On reacted, after reaction successively by fixed blunger 16, material scattering device 17, mix and stir pipe 18 and material-homogenating device 19 is mixed three times
With；After mixing and stirring, the citric acid soluble phosphorus of calcium monohydrogen phosphate and lime phosphorus slag is converted into containing 80% or more water-soluble phosphorus, 5.5% trip below
Qualified calcium superphosphate from acid；The calcium superphosphate of generation is exported by belt conveyor 1, is sealed the mistake that fermentation is got product again
Calcium phosphate.
