Cooling crystallization is required in the production of calcium nitrate, that is, cooling the hot saturated solution to separate or purify the solid substance according to its different solubility at different temperatures. The specific process is to first heat the solution and evaporate the solvent to form a saturated solution. At this time, the temperature of the hot saturated solution is lowered, and the solute whose solubility changes greatly with temperature will precipitate as crystals.

[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figure 1-2 As shown, a cooling crystallization kettle for calcium nitrate comprises a kettle body,

[0016] The kettle body 1 has an opening at the top; a crystallization chamber 11 is provided inside the kettle body 1; a stirring mechanism is provided inside the crystallization chamber 11, and the stirring mechanism is used to stir the calcium nitrate liquid in the crystallization chamber 11 to accelerate the cooling and crystallization of the calcium nitrate liquid; a cooling component is provided between the crystallization chamber 11 and the outer shell of the kettle body 1, and the calcium nitrate liquid in the crystallization chamber 11 is cooled and crystallized by circulating water of the cooling component;

[0017] The kettle body 1 is provided with a plurality of adjusting components 2 on the circumference thereof; the adjusting components 2 include a fixing rod 21; the fixing rod 21 is fixed on the top of the kettle body 1 and faces the inside of the crystallization chamber 11;

[0018] At least one connecting sleeve 23 is sleeved on the fixing rod 21; an adjusting plate 22 is connected to the bottom of each connecting sleeve 23, wherein the connecting sleeve 23 is movably connected to the fixing rod 21, so that the adjusting plate 22 can rotate around the fixing rod 21; at least one connecting portion 24 corresponding to the connecting sleeve 23 is provided on the top of the adjusting plate 22; the adjusting plate 22 is connected to the connecting sleeve 23 through the connecting portion 24;

[0019] When calcium nitrate liquid is placed in the crystallization chamber 11, a part of the adjustment plate 22 is in the calcium nitrate liquid. When the stirring mechanism stirs the calcium nitrate liquid, the calcium nitrate liquid hits the adjustment plate 22, and the adjustment plate 22 tilts along with the rotation direction of the calcium nitrate liquid. On the one hand, the adjustment plate 22 collides with the calcium nitrate liquid to change the fluid state, form a vibration effect, and accelerate the crystallization of the calcium nitrate liquid. On the other hand, when the calcium nitrate liquid in the crystallization chamber 11 rotates, the middle part of the calcium nitrate liquid level is relatively low, and the edge of the liquid level is relatively high. The top of the adjustment plate 22 is higher than the edge of the liquid level. The edge of the liquid level is pressed down by the gravity of the adjustment plate 22 to prevent the edge of the liquid level from being too high and splashing out of the kettle body 1.

[0020] The stirring mechanism includes a stirring motor 31 and a stirring shaft 32; two motor frames 33 are fixed in parallel and spaced apart on the top of the kettle body 1; a mounting plate 34 is fixed above the two motor frames 33; the stirring motor 31 is fixed on the mounting plate 34; the stirring shaft 32 is connected to the output shaft of the stirring motor 31; the stirring shaft 32 passes through the mounting plate 34 and extends downward into the crystallization chamber 11, and the stirring motor 31 drives the stirring shaft 32 to stir the calcium nitrate solution in the crystallization chamber 11;

[0021] In order to improve production efficiency, multiple cooling crystallization kettles are used to cool the crystallized calcium nitrate solution at the same time. When multiple kettle bodies 1 are arranged in parallel, two motor frames 33 are fixed on the top of the multiple kettle bodies 1, and the stirring motor 31 is conveniently installed through the motor frame 33 to position the stirring motor 31;

[0022] In this embodiment, a limiting plate 25 is fixed to one end of the fixing rod 21 close to the middle of the crystallization chamber 11 ; the width of the limiting plate 25 is greater than the outer diameter of the connecting sleeve 23 , and the limiting plate 25 prevents the connecting sleeve 23 from sliding out of the fixing rod 21 .

[0023] The working principle of the utility model is as follows: the calcium nitrate liquid to be crystallized is introduced into the crystallization chamber 11, the cooling component cools the calcium nitrate liquid, the stirring motor 31 is turned on, the stirring motor 31 drives the stirring shaft 32 to rotate, and the calcium nitrate liquid hits the regulating plate 22 when rotating, which accelerates the cooling and crystallization of the calcium nitrate liquid and shortens the cooling and crystallization time.
