Description

A kind of crystallization kettle
Technical field
The invention belongs to technical field of chemical, relate in particular to a kind of crystallization kettle.
Background technology
Crystallization kettle be the industries such as chemical industry, pharmacy, food mixing of materials, heat, lower the temperature, mix reaction equipment in the process such as stirring.Because technique is different with medium, the situation of material has inflammable, explosive, huge poison, HTHP.Whipped form, the rotating speed of equipment, add the requirement difference of gentle cooling.Design and select material, structure and the reductor of this equipment are explosion-proof from requirement of explosion proof is not different yet.
After crystallization kettle is mixing of materials reaction, the crystallizer of interlayer domestic demand chilled water or chilled water reduces heat, its key link is the size of interlayer area, the version of agitator and material outlet form, high accuracy polishing in tank body, and clean and meet technique service condition without the requirement at dead angle in tank body.
Existing crystallization kettle is substantially all to use chuck to carry out coolingly, and jacket for heat exchange area is little, and fluid-flow rate is little, and heat transfer coefficient is not high, thereby causes material cooling inhomogeneous, thereby affects crystal habit.
Summary of the invention
Technical problem to be solved by this invention is: the deficiency existing for prior art, and provide one can increase heat exchange area, improve heat transfer coefficient, improve the crystallization kettle of material lowering temperature uniform degree.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of crystallization kettle, comprise kettle, agitating device, charging aperture, discharging opening and chuck, the bottom of described chuck and top are respectively equipped with water inlet and delivery port, described agitating device comprises the shaft that is provided with inner chamber, the top of described shaft is connected with motor, the intracavity bottom of described shaft is provided with cooling water inlet pipe, described cooling water inlet pipe is communicated with the water inlet of described chuck, the inner cavity top of described shaft is provided with cooling water outlet tube, described cooling water outlet tube extends the top of described kettle, between the bottom inside wall of described cooling water inlet pipe and described shaft, between the inside top wall of described cooling water outlet tube and described shaft, be all equipped with fixed axis, described shaft is provided with multiple paddles, in described paddle, be provided with cavity, the cavity of described paddle is communicated with the inner chamber of described shaft.
Improve as one, described multiple paddles staggered being vertically located on the periphery of described shaft successively from top to bottom, and paddle in same direction is parallel to each other.
Preferably, the vertical section of described paddle is the parallelogram of length 50~60cm, width 30~40cm.
As improving further, the madial wall of described kettle is provided with multiple arc flow baffles.
As further improving, top, middle part and the bottom of described kettle are respectively equipped with thermometer.
Owing to having adopted technique scheme, the invention has the beneficial effects as follows:
Crystallization kettle provided by the invention, in the inner chamber of its shaft, be provided with cooling water inlet pipe and cooling water outlet tube, this cooling water inlet pipe and cooling water outlet tube can make extraneous cooling water circulate in shaft, in each paddle, add the cooling of chuck, increased the heat exchange area of material in kettle, heat transfer coefficient is improved, again by the stirring of shaft and paddle, make material lowering temperature uniform, crystallization is even, has improved lowering temperature uniform degree and the crystallization uniformity of material; Multiple paddles are staggered to be vertically set on shaft and equidirectional paddle is parallel to each other and can makes mixing of materials even, and the mobile effect of playing guiding of arc flow baffle to material indirectly improves the mixed effect of material, makes mixing of materials more even; Thermometer can be used for detecting the temperature of interior each section of kettle, so that the temperature regime in kettle is understood more all sidedly, thereby the crystallization progress of material in grasp kettle.
Brief description of the drawings
Fig. 1 is the structural representation of the crystallization kettle that provides of the embodiment of the present invention;
Wherein: 1-kettle, 2-shaft, 3-paddle, 4-motor, 5-cooling water inlet pipe, 6-cooling water outlet tube, 7-fixed axis, 8-arc flow baffle, 9-thermometer, 11-charging aperture, 12-discharging opening, 13-chuck, 131-water inlet, 132-delivery port.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the structural representation of the crystallization kettle that the present embodiment provides, and for convenience of explanation, this figure only provides the structure division relevant with the present invention.
A kind of crystallization kettle, comprise kettle 1, the top of kettle 1 is provided with charging aperture 11, the bottom of kettle 1 is provided with discharging opening 12, the surrounding of kettle 1 is provided with chuck 13, the bottom of chuck 13 is provided with water inlet 131, the top of chuck 13 is provided with delivery port 132, in kettle 1, be provided with agitating device, agitating device comprises shaft 2 and multiple paddle 3, multiple paddles 3 interlock and are vertically located on the periphery of shaft 2 successively from top to bottom, and the paddle 3 on equidirectional is parallel to each other, in paddle 3, be provided with cavity, the number of paddle 3 is generally 5~8, preferably, the vertical section of paddle 3 is length 50~60cm, width is the parallelogram of 30~40cm, the vertical section of paddle 3 can also be other shapes, shaft 2 is hollow structure, be to be provided with inner chamber in shaft 2, the cavity of paddle 3 is communicated with the inner chamber of shaft 2.
