Abstract
The utility model relates to vacuum evaporation and crystallization equipment. A stirrer and a heating vertical tube bank are arranged in a tank body; a motor and a reduction box which are arranged at the upper part of the tank body are connected with a main shaft of the stirrer; the main shaft is connected with a mechanical seal of which the lower part is additionally provided with a tray; and a drainage tube is arranged in the tray and externally connected with a vacuum pump system. The utility model overcomes the defects of the traditional vacuum evaporation and crystallization equipment, avoids the intrusion of seal impurities and greatly improves the processing quality of materials due to the improvement of automation control degree.
Description
Technical field
The utility model relates to a kind of crystallization apparatus, specifically a kind of vacuum evaporating crystalization equipment.
Background technology
Existing mechanical stirs forced circulation vacuum evaporating crystalization equipment, and its structure is that agitator and heating tubulation group are housed in tank body, is arranged on the motor on tank body top and the main shaft of reductor and agitator and joins, and is connected to mechanical seal on main shaft.Its operation principle is: after material is admitted to tank body from the feed pipe of bottom, carried out indirect by the steam that in heating tubulation group, passes through, aqueous solvent constantly is evaporated under stable vacuum state, the continuous minimizing of solvent makes solution maintain oversaturated state, under the pressure stirring action of agitator, material quickens circulation, separates out crystal and impel crystal to grow up between 60～68 ℃, finishes crystallization process thus.
Use this process equipment, owing to be vacuum state in the tank body, so the sealing of tank body just seems particularly important.Present used agitator sealing of spindles form has two kinds, i.e. packing seal and mechanical seal.The gland sealed seal body is softer, with the friction process of main shaft in, loss is bigger, but because the effect of automatic compacting device in the packing seal, can keep the excellent sealing with main shaft, so always, the packing seal of loss mostly enters in jar interior processing materials, forms impurity.The wearability of mechanical seal is strong, and life cycle is long, but also can enter in the processing materials with the back chip that forms of main shaft friction, pollutes.
In addition, in China sugar enterprise, the vacuum evaporating crystalization operation adopts Artificial Control always, and timing sampling is manually controlled the aperture of related valve again behind the mensuration numerical value, but the very big hysteresis quality of existence is arranged like this, and control accuracy is poor; Though what have has now increased densimeter and charging automatic valve, other parameter still can't in time detect and control.
The utility model content
The purpose of this utility model just provides a kind of vacuum evaporating crystalization equipment, to solve the deficiency that existing vacuum evaporating crystalization equipment exists, improves the processing quality of material.
The utility model is achieved in that a kind of vacuum evaporating crystalization equipment, agitator and heating tubulation group are housed in tank body, being arranged on the motor on described tank body top and the main shaft of reductor and described agitator joins, on described main shaft, be connected to mechanical seal, bottom in described mechanical seal adds pallet, in pallet, be provided with drainage tube, the external vacuum pump system of drainage tube.
After this improvement, the chip that gets off that weares and teares of the mechanical seal on the main shaft is just caught by pallet, and then is relied on negative pressure to extract out by drainage tube by vacuum pump system, the pollution of having avoided chip to enter in the processing materials thus being caused.
In described tank body, be provided with liquid level sensor, pressure sensor, concentration sensor and temperature sensor, described each sensor connects controller by transmitter, be provided with pneumatic control valve on feed pipe that joins with described tank body and steam input pipe, pneumatic control valve is electrically connected with controller.
The utility model is by being provided with liquid level sensor, pressure sensor, concentration sensor and temperature sensor etc., just on tank body, be provided with the test point of liquid level, pressure, concentration and temperature, and detection signal is sent in the controller by transmitter, controller is according to technological process requirement and mathematics of control prototype software, calculate optimal control curve, by program controlled mode control pneumatic control valve events, realize the optimization process of vacuum evaporating crystalization.
The utility model has overcome the deficiency that existing vacuum evaporating crystalization equipment exists, and has avoided the intrusion of sealing impurity, and the raising of automatic controlling level in addition makes the processing quality of material that significantly raising be arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, agitator 8 and heating tubulation group 7 are housed in tank body 5, be provided with motor and reductor 1 on tank body 5 tops, motor and reductor 1 join with the main shaft of agitator 8, on main shaft, be connected to mechanical seal 2, install the pallet 4 of a circle additional in the bottom of mechanical seal 2, an end of drainage tube 3 is fixed in the pallet 4, the external vacuum pump system of the other end.
In addition, the utility model also tank body 5 is provided with microscope 6, be provided with liquid level sensor, pressure sensor, concentration sensor and temperature sensor in tank body 5 inside, each sensor connects controller 9 by transmitter, on feed pipe that joins with tank body 5 and steam input pipe, be provided with pneumatic control valve, pneumatic control valve is electrically connected with controller 9, forms the automation control system of vacuum evaporating crystalization equipment thus.
On controller 9, touch-screen can be set, constitute interactive interface, and the process chart of vacuum evaporating crystalization and various control parameter all can be presented on the touch-screen, the direct labor is come into plain view to production process.
