Description
Technical field
The utility model relates to field of mechanical technique more particularly to evaporated crystallization devices.
Background technique
Evaporative crystallization is one of operation common in industrial production, is widely used in chemical industry, wastewater treatment, pharmacy, light industry etc.
Field.The most important equipment of evaporated crystallization device is crystallizing evaporator, and raw material liq reaches supersaturated shape in crystallizing evaporator
Solute is precipitated in state, obtains crystalline solid.
But in evaporation and crystal process, nucleus can be attached to heat-transfer surface inner surface and fouling, gently then influence heat exchange efficiency, weight
Can then device be made to block, seriously affect evaporated crystallization device normal operation.The material after evaporative crystallization was simultaneously
Saturated liquid, crystal is quickly precipitated after cooling, so that evaporated crystallization device unloading position easily blocks, needs inspection of often stopping
It repairs, has seriously affected the continuous operation of evaporated crystallization device.
Utility model content
The purpose of the utility model is to overcome defects existing in the prior art, provide a kind of steaming for preventing discharge blockage
Send out crystallization apparatus, can effectively solve crystallization apparatus heat-transfer surface fouling and unloading position blocking the problem of.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of evaporated crystallization device preventing discharge blockage, it is characterised in that: the evaporated crystallization device includes evaporation knot
Brilliant device, spiral cutting machine, crystal filter, steam condenser, vacuum pump assembly.
The crystallizing evaporator is equipped with steam inlet, condensation-water drain, material inlet, steam (vapor) outlet, mother liquor entrance, object
Material outlet；It is semi-spiral steam jacket outside crystallizing evaporator, inside sets scraper type agitating paddle, and bottom is cone, and material goes out
Mouth is connected with spiral cutting machine entrance.
Screw drives solids exit is set in the spiral cutting machine, the cooling material of peripheral hardware cooling water pipe, material is through spiral
Blanking machine outlet enters crystallization filter；Crystalline solid is obtained after filtering, and the mother liquor filtered out is returned to via mother liquor reflux entrance
Steam crystallizer.
The crystallizing evaporator steam (vapor) outlet is connected with steam condenser inlet, and what steam condenser was equipped with, which vacuumize, connects
Mouth is connected with vacuum pump assembly.
The beneficial effects of the utility model are: the steam heating evaporation crystallizer outside crystallizing evaporator in semi-spiral casing
Interior liquid evaporates the water and saturated liquid precipitation crystallization is obtained to 50~95 DEG C, and scraper type agitating paddle is stirring in crystallizing evaporator
It can effectively prevent heat-transfer surface fouling while mixing；Base of evaporator is set as taper, prevents crystalline solid accumulation from blocking, together
When spiral cutting machine of the crystalline solid discharging connection containing cooling water pipe, crystallized stock is cooled to 30~70 in blanking machine
DEG C, so that crystal solution solid content increases, and consolidate while the screw driving in blanking machine can guarantee solid content increase
Physical efficiency smoothly discharges.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
According to Fig. 1, the utility model includes crystallizing evaporator 1, spiral cutting machine 2, crystal filter 3, steam condenser
4, vacuum pump assembly 5.
The crystallizing evaporator is equipped with steam inlet 105, condensation-water drain 109, material inlet 106, steam (vapor) outlet
107, mother liquor entrance 108, material outlet 104；It is semi-spiral steam jacket 102 outside crystallizing evaporator, inside sets scraper type and stirs
Paddle 101 is mixed, bottom is cone 103, and material outlet 104 is connected with spiral cutting machine entrance 203.
Screw 201 is set in the spiral cutting machine 2 drives solids exit, 202 cooled material of peripheral hardware cooling water pipe
Material, material enter crystal filter 3 through spiral cutting machine outlet 206；Crystalline solid is obtained after filtering, crystallizes filter mother liquor
Outlet 303 is connected with steam crystallizer mother liquor entrance 108.
The crystallizing evaporator steam (vapor) outlet 107 is connected with steam condenser inlet 401, what steam condenser 4 was equipped with
Interface 403 and vacuum Pump Suction Nozzle 501 are vacuumized, vapo(u)rization system vacuumizing condition is provided.
When the utility model is used, liquid in the steam heating evaporation crystallizer outside crystallizing evaporator in semi-spiral casing
To 50~95 DEG C, evaporates the water and saturated liquid precipitation crystallization is obtained, spiral shell of the crystalline solid discharging connection containing cooling water pipe
Slewing blanking machine, crystallized stock are cooled to 30~70 DEG C in blanking machine, and crystal solution solid content increases, the crystallized mistake of crystal solution
Crystalline product is obtained after filter.
