Description

Currently, conventional thin film evaporators are generally in need of improvement in overall performance.

The invention aims to solve the technical problems that: how to develop a glass-lined thin film evaporator with more excellent performance.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
The utility model provides a glass lining film evaporator, which comprises a kettle body, the input tube, the output tube, the exhaust pipe, the temperature measuring valve, press from both sides the cover, the guide plate, the support, glass lining rotor assembly, motor reducer drive arrangement, wherein, the inner wall of the cauldron body is glass lining material, be provided with input tube and output tube respectively in the upper portion of the cauldron body, be provided with the exhaust pipe in the lower part of the cauldron body, be provided with the temperature measuring valve on the exhaust pipe, be provided with the clamp cover in the outside of the cauldron body, be equipped with the guide plate on pressing from both sides the cover, be fixedly connected with support outside the clamp cover, be connected with glass lining rotor assembly in the internal rotation of cauldron, be connected with motor reducer drive arrangement in the external fixedly connected with motor reducer drive arrangement of cauldron and glass lining rotor assembly transmission.
Preferably, the input pipe is connected with a variable frequency pump.
Preferably, a hot water inlet pipe and a hot water return pipe are respectively connected to the jacket.
Preferably, a film scraper made of PTFE or PEK material is connected to the glass lining rotor assembly.
Preferably, a rack with a double-pivot bearing is fixedly arranged at the top of the kettle body, and a motor speed reducer driving device is fixedly arranged on the rack.
Preferably, a PTFE or PEK distribution plate is fixedly connected to the inner end of the input pipe.
Preferably, the bottom of the kettle body is in a cone shape, and the cone angle of the cone is 90 degrees.
The invention discloses a glass lining film evaporator.
The invention is specially designed for the evaporation separation and purification of heat-sensitive substances and high boiling point liquid substances: the material enters a distribution plate feeding groove of the thin film evaporator through an input pipe, and the distribution plate driven by a rotor uniformly distributes the material on the inner surface of the heating cylinder by utilizing centrifugal force; the movable film scraping device arranged on the rotor spreads the liquid into a uniform film on the surface of the heating cylinder by rotating and can self-clean the inner surface of the cylinder; the low boiling point component in the membranous material is continuously heated and evaporated on the surface, the steam enters the separating cylinder upwards through the pore canal on the distribution disc, and is pumped out and condensed by the vacuum condensing system through the steam outlet; the film scraping device can simultaneously push down the materials until the evaporation residues are pushed to the lower cylinder for collection; the concentrated solution is discharged to a collecting storage tank through a bottom discharge valve or is sent to a thin film evaporator through a pumping system for secondary evaporation.
The technical advantages of the present invention are also focused on the following aspects:
1. The vacuum pressure drop is small: the material vaporization gas is sent to an external condenser from an evaporation surface, and a certain static liquid level pressure difference exists. This pressure drop (Δp) is typically relatively high, sometimes even unacceptably high in a typical distillation apparatus. The materials in the scraper type film evaporator are in the form of films, the vaporized gas has larger passing space, almost no liquid level pressure difference is generated, the pressure in the evaporator can be almost equal to the pressure in the condenser, so that the pressure drop is small, and the loss of vacuum degree is reduced.
2. The evaporation temperature is low: due to the above characteristics, this allows the evaporation process to be kept under a higher vacuum. Since the increase in vacuum corresponds to a decrease in boiling point of the material, the operation can be performed at a lower temperature while reducing the likelihood of thermal decomposition of the product.
3. The heating time is short: due to the independent structure of the scraper type thin film evaporator, the scraper has a pumping function, so that the residence time of the material in the base evaporator is very short, and the material cannot be detained on the surface of the evaporator on a heating surface due to the high-speed turbulence of the material liquid film. Therefore, the invention is particularly suitable for the evaporation of heat-sensitive materials.
4. The evaporation intensity is high: the reduction of the boiling point of the material increases the temperature difference with the heat medium, the function of the film scraping device reduces the thickness of the liquid film in a turbulent state, and reduces the thermal resistance. Meanwhile, the adhesion and scaling of materials on a heating surface are inhibited in the process, and good heat exchange is carried out, so that the total heat transfer coefficient of the scraper type thin film evaporator is improved.
5. The operation elasticity is large: the invention is suitable for treating materials with high viscosity and rapid increase of viscosity along with concentration improvement, which are required to be evaporated smoothly and have heat sensitivity due to the unique performance. It can also be successfully applied to evaporation and distillation of liquid materials containing solid particles, crystallization, polymerization, scaling and the like.
