The high pressure reaction kettle is composed of two parts: a kettle body and a controller. 1) The high pressure reaction kettle body is composed of a reaction vessel, a stirrer and a transmission system, a cooling device, a safety device, a heating furnace and the like.
* The kettle body and the kettle lid are made of 1Cr18Ni9Ti stainless steel. The kettle body is connected with the flange by thread, and the kettle lid is a positive body flat cover. The two are tightly connected by the circumferentially evenly distributed main bolts and nuts.
*The main sealing port of the autoclave adopts the A-type double-line seal, and the other sealing points adopt the sealing form of the arc surface and the line contact of the plane, the arc surface and the arc surface, and the high precision and smoothness of the contact surface are achieved. Sealing effect.
* The outside of the kettle is equipped with a barrel-type silicon carbide core, the electric furnace wire is threaded into the furnace core, and the end of the furnace is threaded through the lower part of the furnace shell, and the rubber sleeve cable is connected to the controller through the connection stud.
* The lid of the kettle is equipped with a pressure gauge, a rupture membrane safety device, a vapor-liquid phase valve, a temperature sensor, etc., so that it is easy to understand the reaction situation in the kettle, adjust the proportion of the medium in the kettle, and ensure safe operation.
*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. By controlling the speed of the servo motor, the purpose of controlling the stirring speed can be achieved.
* The upper part of the spacer is equipped with a speed measuring coil. When the integrated agitator rotates with the inner magnetic ring, the speed measuring coil generates an induced electromotive force. The potential corresponds to the stirring speed. The potential is transmitted to the tachometer to display the stirring speed. .
* A cooling water jacket is installed between the magnetic coupling and the lid. When the operating temperature is high, the cooling water should be passed, and the temperature of the magnetic steel is too high to demagnetize.
8. The bearing adopts 1Cr18Ni9Ti stainless steel bearing or high-strength electrochemical graphite, which is resistant to wear and has a long maintenance period. 2) The reactor controller* is made of standard aluminum alloy casing, and the upper cover can be pulled backwards for maintenance and overhaul. The panel is equipped with a temperature digital display, a voltmeter, a tachometer, and control switches and adjustment knobs for the operator to operate.
*Electrical principle: The electronic components of the stirring control circuit are assembled on a circuit board. The double closed-loop control system has the characteristics of high speed regulation, stable speed, strong anti-interference ability, and has the advantages of limiting overspeed and overcurrent. Protection function, adjust the "speed" knob to change the DC voltage of the DC motor, thus changing the speed of the motor to achieve the purpose of controlling the stirring speed.
*The heating circuit adopts the solid state relay (commonly known as the voltage regulating block) to regulate the pressure, so that the heating circuit tends to be simplified. The heating power can be adjusted by adjusting the "pressure regulating" knob. At the same time, the control part of the heating circuit is equipped with an intelligent digital display. The heating temperature is adjusted according to the requirements of the process, and the temperature control accuracy is extremely high. * All external leads are led out from the rear panel through the waterproof connector from the terminal block in the controller.
