Technical Field

The invention relates to desublimation crystallization equipment, and belongs to the field of chemical equipment.

Background

The evaporative crystallization process of the desublimation crystallization equipment is a common operation unit in pharmaceutical and chemical processes, and is very commonly applied to almost all production procedures of crystalline drugs. The evaporative crystallization commonly used by the current enterprises mainly comprises a heat convection type and a forced circulation type. The two types of evaporative crystallizers are mostly subjected to forced external circulation evaporative crystallization. The principle of the evaporator is that a material solution is heated in an external heater under the action of a pump and is evaporated in the evaporator, after a plurality of cycles, a solute is precipitated and crystallized after the concentration of the solution exceeds the solubility at the temperature, and the solution with crystals in the state is continuously heated repeatedly under the action of the pump.

Because current crystallization equipment is carrying out the during operation, because be difficult to swiftly collect the crystallization, because the inside crystallization of casing does not have timely processing to fall after long-time cooling, excessive crystallization can cause the influence to the subsequent handling simultaneously, leads to the cooling effect to descend easily, can probably lead to a large amount of crystallization to be difficult to in time collect in the casing after long-time the use, simultaneously because the clearance of being not convenient for, be unfavorable for crystallization equipment's permanent use.
