Description
Technical field
A kind of aluminum sulfate preparation cooling device is the utility model is related to, belongs to aluminum sulfate technical field of processing equipment.
Background technology
Aluminum sulfate is a kind of white orthorhombic system crystalline powder, mainly as gum rosin, wax emulsion etc. in paper industry
The precipitating reagent of sizing material and as staying agent etc. in foam annihilator.After the completion of aluminum sulfate reacts in a kettle, the production of its solid
Product need crystallisation by cooling immediately, and the aluminum sulfate after crystallization is transported in pulverizer again carries out mechanical crushing, in the prior art sulfuric acid
The cooling device work efficiency of aluminium is low, crystallization time is longer and percent crystallization in massecuite is not high, has been unable to meet aluminum sulfate large-scale industry
Production needs.
Utility model content
To solve problems of the prior art, the utility model provides that a kind of cooling velocity is fast, crystallisation by cooling rate
High aluminum sulfate preparation cooling device.Concrete technical scheme is as follows：
A kind of aluminum sulfate preparation cooling device, including babinet, the babinet is interior to be equipped with crystallizing pond, the babinet and crystallization
Cold air path is equipped between pond, the cold air path connects cool-air supplier, and the crystallizing pond upper end is equipped with feed inlet, described
Some cooling tubes are equipped with crystallizing pond, the cooling tube lower end connects the cold air path, and the cooling tube upper end opening is described
Cooling tube upper end extends to the external world through the crystallizing pond upper end, and the crystallizing pond lower end is equipped with infundibulate discharge port, the leakage
Bucket shape discharge port connects solid-liquid separator, and described solid-liquid separator one end connects storage tank, and the solid-liquid separator other end connects
Evaporator is connect, the evaporator connects the feed inlet.
Preferably, middle part is equipped with agitating shaft in the crystallizing pond, and the agitating shaft upper end connects motor, the motor
It is fixed on the crystallizing pond, the agitating shaft is equipped with paddle blade, and the spacing between the paddle blade becomes from top to bottom
It is small.
The beneficial effects of the utility model are：The utility model aluminum sulfate preparation cooling device, cooling wind pass through cold air
Passage cools down the outer wall of crystallizing pond, and cold air path connection cooling tube, cooling tube is located in crystallizing pond in crystallizing pond
The direct crystallisation by cooling of sulfuric acid molten aluminum, aluminum sulfate is carried out crystallisation by cooling by cold air path and multiple cooling tubes, crystallization rate is fast,
It is good to crystallize uniformity；Aluminum sulfate after crystallization is entered in solid-liquid separator by infundibulate discharge port carries out mother liquor and aluminum sulfate crystalline substance
Body separates, and still remaining has aluminum sulfate in the mother liquor after separation, and mother liquor reenters crystallizing pond after evaporator evaporates certain liq
Crystallized again, improve percent crystallization in massecuite.
Further, middle part is equipped with agitating shaft in crystallizing pond, and agitating shaft is equipped with paddle blade, between paddle blade
Spacing is less and less from top to bottom, can be sufficiently stirred aluminum sulfate to be crystallized, further improve crystallization rate and uniformity.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of aluminum sulfate preparation cooling device, including babinet 1, the babinet
Crystallizing pond 2 is equipped with 1, cold air path 3 is equipped between the babinet 1 and crystallizing pond 2, the cold air path 3 connects cool-air feed
Device 10,2 upper end of crystallizing pond are equipped with feed inlet 9, are equipped with some cooling tubes 4 in the crystallizing pond 2, under the cooling tube 4
End connects the cold air path 3, and 4 upper end opening of cooling tube, 4 upper end of cooling tube is prolonged through 2 upper end of crystallizing pond
The external world is extended, 2 lower end of crystallizing pond is equipped with infundibulate discharge port 5, and the infundibulate discharge port 5 connects solid-liquid separator 6, institute
6 one end of solid-liquid separator connection storage tank 7 is stated, 6 other end of solid-liquid separator connects evaporator 8, and the evaporator 8 connects
The feed inlet 9.
The utility model is when it is implemented, aluminum sulfate to be crystallized enters crystallizing pond, cool-air supplier 10 from feed inlet 9
Start to convey cold air into cold air path 3, the cold air in cold air path 3 is absorbed by the outer wall of crystallizing pond 2 takes away heat
And realize to the aluminum sulfate cooling crystallization in crystallizing pond 2, while cold air enters cooling tube by the bottom of cold air path 3
In 4, cooling tube 4 carries out decrease temperature crystalline to the aluminum sulfate of periphery, and the inside and outer wall for realizing crystallizing pond cool down, improves cold at the same time
But speed and uniformity；The aluminum sulfate and mother liquor that crystallisation by cooling separates out enter solid-liquid separator 6, solid-liquid through infundibulate discharge port 5
After separator 6 separates mother liquor with aluminum sulfate, aluminum sulfate is stored into storage tank 7, and mother liquor enters evaporator 8 and evaporates moisture, steams
Concentration becomes higher after hair crystallizes again through feed inlet 9 into crystallizing pond again, improves percent crystallization in massecuite.
Middle part is equipped with agitating shaft 11 in the crystallizing pond 2, and 11 upper end of agitating shaft connects motor 13, the motor
13 are fixed on the crystallizing pond 2, and the agitating shaft 11 is equipped with paddle blade 12, the spacing between the paddle blade 12 from
It is less and less under, during aluminum sulfate crystallisation by cooling at the same time start motor 13 drive agitating shaft 11 rotate, to aluminum sulfate into
Row uniform stirring, is conducive to further improve crystalline rate.
The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model
Embodiment, it is impossible to be construed as limiting the scope of the utility model, all impartial changes made according to the scope of the utility model
Change and improvement etc., should all still belong within the utility model covering scope.
