Description
Technical field
The utility model relates to a kind of chemical field and is used to evaporate device with crystallization, especially a kind of crystallizing evaporator.
Background technology
In the prior art, the compound mode that the evaporative crystallization operation generally takes heat exchanger to add crystallizing evaporator is operated, wherein adopt the mode of heat exchange to heat in the heat exchanger, the heating back adopts the mode that stirs to carry out evaporative crystallization in crystallizing evaporator, between heat exchanger and crystallizing evaporator, get in touch by the circulating pump of big flow, and provide crystalline form to control the power of required hydrodynamics behavior by circulating pump, material is easily because of the cooling crystallization in operating process because in the circulating pump, thereby cause the circulating pump serious wear, the sealing difficulty; Difficulty is regulated in the required hydrodynamics behavior of crystalline form control in the cyclic process simultaneously, and when flow was turned down, material crystallization in heat exchanger easily caused heat exchange pipeline to stop up.
The utility model content
Technical problem to be solved in the utility model is, a kind of crystallizing evaporator that can flexible modulation product crystalline form size is provided at above-mentioned deficiency.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of crystallizing evaporator, wherein: comprise vertical setting tank body, be installed in adjusting and reducing speed system, being positioned at the tank body top and adjusting and reducing the hand-hole of speed system one side, be installed in demister on the hand-hole, vertically be installed on the stirring power transmission shaft of tank body center of tank body top; The upper end of stirring power transmission shaft with adjust and reduce speed system and link to each other, the lower end is provided with paddle; In the inner chamber of the middle and lower part of tank body the guide shell concentric with tank body is installed, guide shell is fixed on the tank body by guide shell upper support and guide shell lower support; Between the annular space of guide shell and tank body heat exchanger coil is installed, the heat exchange medium inlet on heat exchanger coil one end and the tank body is connected, and the other end is connected with heat exchange medium exit; The bottom of tank body is provided with the outlet of material, and described paddle adopts pusher paddle.
In the utility model, the distance of the upper edge of guide shell and heat exchanger coil upper edge can be set to 0～1.5 meter.Described guide shell upper support and guide shell lower support preferably adopt four steel pipes or band steel to form respectively, make it connect firm supporting.Described heat exchanger coil preferably is fixed on the tank body, and two ends gather pipe by coil pipe separately and be connected with heat exchange medium exit with heat exchange medium inlet, and it is more firm to fix like this, and heat exchange is rapider effective.When the utility model uses, enter in the tank body from hand-hole after the foam removal of material process demister, and progress in the guide shell, feeding heat exchange medium in the heat exchanger coil material is heated, material crystallization under the acting in conjunction of heating and stirring also finally breaks away from tank body from the outlet of material.
The utility model is coupled as one with traditional heat exchanger and crystallizing evaporator, make compact conformation, removed the high circulating pump member of fault rate in traditional evaporative crystallization operation, during use, because the circulation of material is to finish by the tank interior that constrains in of pusher paddle and guide shell convection cell, therefore, all defect that does not exist circulating pump to bring.Because the utility model is to adopt coil pipe as heat exchanger, removed the heat exchanger in traditional evaporative crystallization operation, reduced by a pressure vessel, security is improved, pass through to regulate the rotating speed of paddle during use, internal circulating load that can the flexible modulation material because internal circulating load is relevant with degree of supersaturation, thereby can be regulated the size of product crystalline form with the adjusting rotating speed of agitator.
In sum, than prior art, the utility model is adjusted and reduced speed system and is regulated rotating speed of agitator, and then can flexible modulation product crystalline form size, and product granularity can be adjusted between 0.1 ~ 0.5mm.The utility model also possesses compact conformation simultaneously, and equipment cost and operating cost are low, and service cycle is long, and energy consumption is low, simple operation and other advantages.
