Abstract
An enhanced crystallizer comprises an equipment cylinder, a pushing type stirring paddle, an outer draft tube, a central draft tube, a speed reducer, a frequency modulated motor and a frequency modulator. The central draft tube is disposed inside the outer draft tube which is disposed inside an internal cavity formed by the equipment cylinder, an overflow weir is arranged at the upper between the outer guide shell and the equipment cylinder, the bottom of the equipment cylinder is equipped with a stirring rake capable of preventing crystal from hardening, and a settlement inclined plate is arranged on the inner wall of the equipment cylinder and the outer draft tube wall. The enhanced crystallizer has simple structure, reliable operation, convenient maintenance, low manufacture cost and high yield, which is particularly adapted for operation occasions of obtaining products by mother solution crystallization and having requirements to crystal sizes.
Description
Technical field
The utility model relates to a kind of crystallizer, especially relates to a kind ofly being applicable to that inorganic salts or sylvite production need that thin polycrystalline growing, coarse-grain carefully brilliantly separate, the crystallizer of coarse-grain sedimentation discharge process.
Background technology
At present, the crystallizer that in inorganic salts or sylvite production, adopts, for example, Chinese patent 03227265 disclosed crystallizer, its crystallizer equipment barrel is made of top cylinder, the little cylinder in bottom, middle part reverse frustoconic null device cylindrical shell three joints, and other is provided with casing drum, circulating pump and center circulation pipe.Material circulation in this crystallizer and crystal suspend and rely on circulating pump promotion material to realize by the center circulation pipe, because no special crystallite is caught, thin polycrystalline growing district, the mother liquor the inside that makes overflow discharge has been carried a large amount of crystallite, thin brilliant secretly, thereby reduced the yield of active ingredient, thereby product yield decreases also.And for example, Chinese patent 200420008006 disclosed crystallizers, this crystallizer internal cavity be provided with one suitable for reading for tubaeform central tube and an end opening be flaring guide shell, material is by being provided with two-stage, the downward impeller of active force in the crystallizer on the central upper portion shaft, and the make progress impeller of equidirectional high speed rotation of active force is set on bottom centre's shaft, the interior levels material of crystallizer is fully mixed, and realize the interior outer circulation of fluid at central tube.Though this crystallizer has solved some problems that other crystallizers exist, still be entrained with a large amount of crystallites in the mother liquor that overflow is discharged, make the yield of active ingredient of mother liquor the inside still not reach ideal value, the output of product improves limited.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective of existing crystallizer, provide a kind of can continuous feed, effectively improve yield, regulate product crystal thickness, simple in structure, low cost of manufacture, the enhancement mode crystallizer that fault is few.
The purpose of this utility model is achieved through the following technical solutions: it comprises equipment barrel, pusher paddle, external flow guiding cylinder, central draft tube, reductor, frequency modulation motor and frequency modulator, described pusher paddle is installed in the central draft tube, it is characterized in that, described central draft tube is installed in the external flow guiding cylinder, described external flow guiding cylinder is installed in the inner chamber of equipment barrel formation, and top is provided with downflow weir between external flow guiding cylinder and the equipment barrel.
Below be preferred version:
On equipment barrel inwall and the external flow guiding cylinder wall sedimentation swash plate is installed.The sedimentation swash plate can carry out crystallite catches, and reduces the overflow solid content.The quantity that is provided with of sedimentation swash plate can be definite according to actual conditions.
The equipment barrel bottom is provided with raker stirrer, to prevent the crystal slab knot.
The utility model is simple in structure, and reliable operation is easy to maintenance, low cost of manufacture, and the product yield height is specially adapted to obtain product and the product crystal size is had the workplace of requirement by mother liquor crystallization.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, present embodiment comprises raker stirrer 1, the pusher paddle 2 that prevents crystal knot plate, equipment barrel 3, downflow weir 5, external flow guiding cylinder 6, central draft tube 7, reductor 8, frequency modulation motor 9 and frequency modulator (not shown), described pusher paddle 2 is installed in the central draft tube 7, described central draft tube 7 is installed in the external flow guiding cylinder 6, described external flow guiding cylinder 6 is installed in the inner chamber of equipment barrel 3 formations, described equipment barrel 3 inwalls are equipped with sedimentation swash plate 41, and sedimentation swash plate 42 is installed on the external flow guiding cylinder outer wall.
During the crystallizer operation, pusher paddle 2 make mother liquor central draft tube 7 in on mobile, between external flow guiding cylinder 6 inwalls and central draft tube 7 outer walls, flow downward, form circulation, size has reached the crystal grain of regulation requirement and has concentrated in the sedimentation of guide shell bottom, discharged by discharging opening, crystal grain less than normal is realized the separation of thickness crystalline substance along with mother liquor continues to circulate between two guide shells.And the thin crystalline substance of separating continues to grow up in circulation, reaches requirement until granular size, concentrates in the sedimentation of guide shell bottom and is discharged by discharging opening.So go round and begin again, realize the continuous operation of crystallizer.Regulate the rotating speed of frequency modulation motor 9, can regulate Recycling Mother Solution speed, thereby the control crystal reaches the granular size of settlement request.Fresh mother liquor adds from external flow guiding cylinder 6, and poor mother liquor is discharged from downflow weir 5 overflows.When poor mother liquor overflow was discharged, the crystallite capture area of the crystallite of being carried secretly by being made of equipment barrel 3 and external flow guiding cylinder 6 by sedimentation swash plate 41 and drop angle plate 42 seizure of tackling, was settled down to the guide shell bottom and participates in Recycling Mother Solution, to improve the material yield.
Claims (3)
1, a kind of enhancement mode crystallizer, comprise equipment barrel, pusher paddle, external flow guiding cylinder, central draft tube, reductor, frequency modulation motor and frequency modulator, it is characterized in that, described central draft tube is installed in the external flow guiding cylinder, described external flow guiding cylinder is installed in the inner chamber of equipment barrel formation, and top is provided with downflow weir between external flow guiding cylinder and the equipment barrel.
2, enhancement mode crystallizer according to claim 1 is characterized in that, on equipment barrel inwall and the external flow guiding cylinder wall sedimentation swash plate is installed.
