Author:


High pressure chemical reactor consists of reaction vessel, agitator and transmission system, cooling device, protective device, heating furnace, etc.

High pressure chemical reactor consists of reaction vessel, agitator and transmission system, cooling device, protective device, heating furnace, etc.

High pressure chemical reactor

1. The kettle body and the kettle cover are made of 1Cr18Ni9Ti stainless steel. The kettle body is connected with the flange through threads, and the kettle cover is a normal plate cover. The two are fastened and connected by main bolts and nuts distributed evenly around the circumference.
2. The main sealing port of the high pressure chemical reactor adopts A-type double-line sealing, and the other sealing points adopt the sealing form of line contact between arc surface and plane, arc surface and arc surface, depending on the high precision and smoothness of the contact surface. , to achieve a good sealing effect.
3. A barrel-shaped silicon carbide furnace core is installed on the outside of the kettle. The electric furnace wire is passed through the furnace core, and its end is pierced from the lower part of the furnace shell side.
4. The lid of the high pressure chemical reactor is equipped with pressure gauges, protective devices, vapor-liquid phase valves, temperature sensors, etc., which are convenient to know the reaction situation in the kettle at any time, adjust the medium ratio in the kettle, and ensure good operation.
5. The coupling is mainly composed of a pair of inner and outer magnetic rings with strong magnetic force, and there is a pressure-bearing spacer in the middle. The agitator is driven by a servo motor through a coupling. The purpose of controlling the stirring speed can be achieved by controlling the speed of the servo motor.
6. The upper part of the spacer is equipped with a speed measuring coil. When the integrated stirrer and the inner magnetic ring rotate, the speed measuring coil will generate an induced electromotive force, which corresponds to the stirring speed. The potential is transmitted to the tachometer to display the stirring speed. Rotating speed.
7. A cooling water jacket is installed between the magnetic coupling and the kettle cover. When the operating temperature is high, cooling water should be passed through, and the magnetic steel temperature is too high and demagnetized.
8. The high pressure chemical reactor bearing adopts 1Cr18Ni9Ti stainless steel bearing or high-strength electrochemical graphite, which is resistant to wear and tear and has a long maintenance period.
