Overview
Lab scale high pressure reactor is a commonly used biochemical instrument, which is widely used in modern fine chemical industry, biopharmaceutical, scientific research and experiment industries, etc. Reaction is an ideal instrument and equipment for teaching, experiment, pilot test and production.
Lab scale high pressure reactor According to the process requirements, there are two kinds of autoclaves with agitator and without agitator. The structure of the former is the same as that of the stirring equipment.
The structure and principle of lab scale high pressure reactor:
1. The kettle body and lid of the lab scale high pressure reactor are made of stainless steel. The kettle body is connected to the flange through threads, and the kettle lid is a flat flat lid. The two are fastened and connected by the main bolts and nuts uniformly distributed in the circumferential direction.
2. The main sealing port of the lab scale high pressure reactor adopts A-type double-line sealing, and the rest of the sealing points adopt the sealing form of the line contact between the arc surface and the plane, and the arc surface and the arc surface, relying on the high precision and high precision of the contact surface. smoothness, to achieve a good sealing effect.
3. The body of the lab scale high pressure reactor is equipped with a barrel-shaped silicon carbide furnace core, and the electric furnace wire passes through the furnace core, and its end passes through the lower part of the furnace shell side, and is connected to the controller through a connecting stud and a rubber-sheathed cable.
4. The lid of the lab scale high pressure reactor is equipped with pressure gauges, bursting membrane safety devices, vapor-liquid phase valves, temperature sensors, etc., so that it is convenient to know the reaction situation in the kettle at any time, adjust the medium ratio in the kettle, and ensure safe operation.
5. The coupling is mainly composed of a pair of inner and outer magnetic rings with strong magnetic force, and a pressure-bearing spacer in the middle. The stirrer is driven by a servo motor through a coupling.
6. A tachometer coil is installed on the upper part of the spacer. When the integrated stirrer and the inner magnetic ring rotate, the tachometer coil will generate an induced electromotive force, which corresponds to the stirring speed. The electric potential is transmitted to the tachometer to display the stirring Rotating speed.
7. There is a cooling water jacket between the magnetic coupling and the lid of the kettle. When the operating temperature is high, the cooling water should be passed through, and the magnetic steel will be demagnetized if the temperature is too high.
8. The bearing adopts 1Cr18Ni9Ti stainless steel bearing or high-strength electrochemical graphite, which is wear-resistant and has a long maintenance cycle.
Features
lab scale high pressure reactor features:
1. The main body of the lab scale high pressure reactor is made of stainless steel 304 or 316.
2. Stainless steel stirring rod, suitable for stirring various solvents.
3. Stirring by deceleration booster motor, stable operation, large torque, no spark, long life.
4. PTFE components + mechanical seal, proprietary technology, can ensure good vacuum and long service life.
5. The governor of the lab scale high pressure reactor is dual-digital display of speed and temperature (can display the temperature in the kettle). The speed can be set by the speed control knob, which is intuitive and convenient; it is also equipped with a temperature measuring probe for the temperature in the kettle.
6. The overall structure is compact and reasonable, equipped with universal wheels, which can be moved as a whole and easy to operate.
7. The stainless steel discharge valve can effectively reduce the dead angle of stirring, and the discharge is convenient.
Precautions during use of lab scale high pressure reactor:
1. In order to ensure the safe use of the lab scale high pressure reactor, please be sure to ground the wire, and please do not work with empty materials or dry burning. Please do not work continuously for more than 72 hours. If there is pressure in the kettle, please do not open the lid of the kettle. You should first release the pressure from the valve before opening the lid of the kettle.
2. When installing the lab scale high pressure reactor, please first correspond to the 0 key on the edge of the kettle lid and the 0 key on the edge of the kettle body, and ensure that the six screws are installed diagonally and tightened at the same time. Please be careful with it! Do not bump the sealing surface of the upper and lower kettle body! Bump deformation is easy to leak.
3. In order to prolong the use of the lab scale high pressure reactor, the motor of the magnetic stirrer has a fan cooling function. When it is used for heating experiments, especially for high-temperature heating experiments, the instrument cannot be used for heating alone, and the motor must be adjusted to rotate Or medium speed rotation state (or idling).
4. At the end of high-temperature heating, please turn off the heating switch first, and then turn off the stirring switch after the residual temperature dissipates for a few minutes.
5. When the liquid enters the case, please turn off the power quickly, and put the instrument in a ventilated place to dry before using it, so as to avoid the danger of electric leakage or electrical short circuit.
6. When the ambient humidity is relatively high, there may be induction electricity transmitted to the shell through the insulation layer, please make sure to ground the wire to avoid leakage. And pay attention to ventilation. Relative humidity range 35%-85% (non-condensing).
7. When the lab scale high pressure reactor is not used for a long time, please store the instrument in a dry and non-corrosive environment.
8. When doing experiments, the working volume is at most 2/3 of the volume of the kettle body, and must not exceed its volume.
9. It is recommended that if the PTFE lining is used in the experiment, the set temperature should not exceed 200°C, and if the PPL lining is used, the set temperature should not exceed 240°C. If the specified temperature is exceeded, the PTFE lining and PPL lining are easily deformed.
