Experimental apparatus for fine plate glass distillation
1. summarize
Along with the market competition, each side faces the product quality request to improve unceasingly, USES the precise distillation method to improve the product quality, is other many purification method irreplaceable economic important means.Laboratory precision distillation unit is fine chemical industry, daily chemical, light chemical, pharmaceutical industry, petroleum refining, agricultural and forestry chemical and other departments of product development experiments, purification, refined substances necessary equipment, is also an important experimental equipment for scientific research and teaching in colleges and universities.In order to meet the requirements of high precision, high stability, easy operation and beautiful device proposed by the r&d personnel for the distillation unit, our technical personnel have carried out research and development and upgrading of the old distillation unit.
First, upgrade the original glass equipment. When the vacuum insulation tower is operated with high boiling point, the glass will expand and contract due to high temperature, which will cause the glass vacuum layer to break.The distillation head is also upgraded to a one-piece, using jacket and serpentine double condensing pipe cooling, with tower top temperature measurement;The receiving bottle is changed to a graduated one with feeding at the bottom. A new glass vacuum sampling system is developed in the device. When sampling is needed in distillation operation, the vacuum of the system will not be destroyed to ensure the normal operation of the experiment.At the same time, the device is also equipped with a snake-shaped coil cold trap and vacuum system. These components are added so that the low-boiling products will not be vacuumed during the operation of the experiment and the vacuum degree required during the experiment can be manually adjusted.
Secondly, the backflow ratio control console is redeveloped. The console is designed with manual/automatic control methods, and the operation is realized by adjusting the time of backflow/recovery through the instrument.In order to solve the problem that the electromagnetic coil will burn out due to the high temperature caused by the long working time of the electromagnetic coil and affect the experimental operation, the technicians have also developed a pneumatic control reflux ratio, which can realize reflux/extraction by pushing the magnet through the cylinder. Such a design reflux ratio operation is very stable and reliable, and it can work on time.
The electric heating cover has been changed from the ordinary electric heating cover to the magnetic stirring intelligent electric heating cover, with accurate temperature control and stable stirring rate.The tower top condenser is also equipped with a domestic/imported high and low temperature cycle machine.
This device consists of four flask, custom rectification, rectification tower, straight pipe, vacuum packing, glass sampler, three even receiver, receiving bottles, cold trap digital display meter, vacuum pump, vacuum buffer tank, vacuum, temperature, pressure measurement, constant temperature heating main components, such as heating cycle device and so on, have a variety of equipment specifications, available for refined need to choose, with different products, all glassware connection parts are all made of the connection of the mouth, the mouth clamp fixed, installation is very convenient to replace;The company can also design and manufacture special parts for the special requirements of user product test.The whole set of device is made of stainless steel, which is an integral movable frame, which is not only beautiful, but also easy to operate.
Technical parameters:

5. Tower kettle volume: select according to the parameter table.
6. The capacity of the receiving bottle on the top of the tower is configured according to the capacity of the tower kettle. There are scales on the surface of the receiving bottle and discharge materials at the bottom.
7. The abdominal wall jacket condenser on the top of the tower is equipped with a small temperature control system, the temperature range: **5~**0℃.
8. The tower top adopts electromagnetic coil reflux ratio to control reflux/recovery.
9. Pressure sensors of domestic/imported brands are equipped at the bottom and top of the tower.
*0. Vacuum pump: domestic/imported for customers to choose
*1. Vacuum buffer tank: volume 2L ~ 5L, equipped with vacuum micro manual regulating valve and vacuum digital display.
*2 control system is divided into PLC integrated control, instrument control cabinet two control forms for customers to choose, to achieve temperature, pressure, reflux ratio, mixing speed control and data monitoring, and so on.
*3. Low temperature circulation tank: domestic/imported for customers to choose.
The above parameters are only for reference, the specific technical requirements according to customer demand customized.
