Abstract
The utility model relates to a crystallizing tank for producing citric monohydrate crystals. The tank comprises a tank body, a tank bottom and a stirrer, wherein the tank body is provided with a charging port and a discharging port, and a stirring shaft of the stirrer extends into the tank body; the tank bottom is of a convex arc shape; and a plurality of impeller-type stirring paddles are arranged at the upper part of the stirring shaft, and an anchor-type stirring paddle is arranged at the lower part of the stirring shaft and is located in an arc-shaped structure of the tank bottom. According to the crystallizing tank for producing citric monohydrate crystals, the stirring mass and heat transfer effect is good, and crystallizing slurry liquid can be guaranteed of stable liquid flow, no sinuous flow and no dead corners; and the structure is simple, and the use is convenient.
Description
Technical field
The utility model belongs to the chemical industry equipment field, is specifically related to crystallizing tank, relates in particular to the crystallizing tank that is specifically designed to the Citric Acid Mono crystal production.
Background technology
Produce the Citric Acid Mono crystal and adopt cooling to stimulate crystallization processes usually, the related mass transfer of crystallization process, heat transfer, secondary nucleation etc. all with stir closely related.Citric Acid Mono is in the decrease temperature crystalline process, and slurry density height need fully stir the requirement of satisfying mass transfer, heat transfer when could guarantee the suspension crystal.
There are problems such as stirring efficiency is low, stirring mass-and heat-transfer effect is bad, crystal mass difference mostly in Citric Acid Mono crystal production crystallizing tank at present; Stirring intensity is easy to generate for a short time and stirs the dead angle, and the generation of degree of supersaturation and distribution are restricted, and solution mixes inhomogeneous, and particle easily deposits or be agglomerated into the bulk druse.
The utility model content
At the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of Citric Acid Mono crystal production crystallizing tank.It is effective that the utility model stirs mass-and heat-transfer, can guarantee stable, the no sinuous flow of slurry liquid stream, no dead angle, and simple in structure, easy to use.
The technical scheme that the utility model adopts is as follows:
Citric Acid Mono crystal production crystallizing tank comprises tank body, jar end and agitator, and tank body is provided with charging aperture, and a jar end is provided with discharging opening, and the shaft of agitator stretches in the tank body; The jar end, be the circular-arc of evagination; Described shaft top is provided with a plurality of vane type stirring arms, and the bottom is provided with anchor formula paddle, convex structure at the bottom of anchor formula paddle is positioned at jar.
Its further technical scheme is:
Charging aperture is positioned at the tank body top.
Diapire middle part at the bottom of discharging opening is positioned at jar.
Preferably, the quantity of vane type stirring arm is two.
Compare with existing Citric Acid Mono crystal production crystallizing tank, the utlity model has following useful technique effect:
1. a plurality of vane type stirring arms are set respectively in the shaft upper and lower and an anchor formula paddle is united stirring, the stirring efficiency height can guarantee that liquid stream is stable in the crystallizing tank, no sinuous flow, and no dead angle, stirring mass-and heat-transfer effect is good, and crystallization effect is good.
2. the convex structure of evagination is adopted at jar end, adapts with the shape of anchor formula paddle, and conventional pyramidal structure more is conducive to the fluid motion of crystal slurries, does not produce to stir the dead angle.
3. simple in structure, floor space is little, and operating cost is low, and is easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises tank body 1, jar end 2 and agitator 3, and tank body 1 is cylindric, and the top is provided with charging aperture 6, and a jar diapire middle part, the ends 2 is provided with discharging opening 7, and the shaft of agitator 3 stretches in the tank body 1; The jar end 2, be the circular-arc of evagination; Described shaft top is provided with two vane type stirring arms 4, and the bottom is provided with anchor formula paddle 5,2 convex structures at the bottom of anchor formula paddle 5 is positioned at jar.
During practical application, obtaining the citric acid concentrate from the citric acid fermentation broth of workshop through removal of impurities, purification, after concentrating pumps in the crystallizing tank through charging aperture 6, start agitator 3, under two vane type stirring arms 4 and anchor formula paddle 5 continuous stirring condition, this citric acid concentrate stimulates crystallization by cooling, the slurry that generates is pumped by discharging opening 7, enters next production process.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion within protection domain of the present utility model, can be done any type of modification referring to claim.
