Laboratory Reactor – Chemical Reactor Vessel

The laboratory reactor can realize the heating, evaporation, cooling, and low-speed mixing reaction functions required by the process. Therefore, the pressure requirements of the reaction process also have different requirements on the design of the container. Production must be processed, inspected, and debugged in strict accordance with corresponding standards. Laboratory reactors have different design structures and parameters due to different production processes and operating conditions. In other words, the structure of the laboratory reactor is different and it is a non-standard container equipment.

The laboratory reactor is a comprehensive reaction vessel designed to design the structure and function of the reaction part and the accessories according to the reaction conditions. From the beginning, supply-reaction-raw materials have completed the preset reaction stages with a high level of automation, and important parameters such as temperature, pressure, kinetic control (stirring, explosion, etc.), reactant/product concentration, etc. during the reaction process all can be strictly controlled. Its structure generally consists of a floating body, a transmission device, a mixing device, a heating device, a cooling device, and a sealing device. Corresponding auxiliary equipment: fractionation column, condenser, water sprayer, collection tank, filter, etc.

The structure principle of laboratory reactor

The seal of the floating body and the floating cover is a triangular linear seal, which has a long service life.

Two open snap rings are used to fix the main seal ring, resting freely on the shoulders of the buoy and the bottle lid, and the torque of the eight main bolts is balanced to tighten the buoyancy seal. When disassembling, loosen the 8 main bolts, open the snap ring, and you can lift the kettle lid, which is convenient.

The kettle cover and the guide po

Valves include a weather valve, liquid phase valve (also known as plug valve), safety burst valve, supply valve, and discharge valve, which can be increased or decreased according to user requirements. The structure of the valve is a reciprocating structure, which is characterized by an increase of 1.5 times the sealing life of the rotary valve. There are two types of bursting valves: double safety devices and single safety devices. The bursting membrane is delivered from the factory and cannot be adjusted or loosened arbitrarily. The pressure gauge is marked on it.

The rotary stirring adopts a cylindrical magnetic coupling structure, and the magnitude of the torque is determined by the magnetic material. Generally, strong magnetic rare earth is used, and the motor is used as the driving force to generate sufficient stirring force in the mixer through coupling. The slurry can be replaced together with the operator. Anchors, boxes, earth dragon worm gears, and other components have applications to various material viscosities.st are connected by the lift arm, the lift hand wheel shakes, the lift bar moves, the guide post moves up and down, left and right, and the lift arm moves freely under the friction-reducing action of the ball.

The rotation of the lid and the inversion and reset of the floating body. Raise the kettle cover to a certain height through the lifting handwheel and the lifting rod, loosen the torque of the tightening hand on the arm, and adjust the movable key pot cover by pressing the position by hand, and then it can be rotated left and right. Release the tightening hand of the turntable again and twist it, press and hold the rotating hook to turn the handwheel to ensure that the kettle body has a certain rewinding angle, then release the rotation, and press the hook to rewind the tape. When the auxiliary body needs to be reset, the handwheel needs to be shaken. Press and hold the rotating ring to quickly reset. The auxiliary body needs to pour out the handwheel to control the speed to achieve a reset.

Precautions for laboratory reactors

1. The laboratory reactor works at room temperature, and the cooling water must be passed normally to prevent the reduction of the magnetic force of the magnet and the wording.

2. Heating setting and heating rising speed (100/h), too high a rising speed is not allowed.

The use and management of laboratory reactors

To use the laboratory reactor, close the refrigerant line valve, put the remaining refrigerant in the bottle-proof pot and the clamp, input the material, start the mixer, then turn on the steam valve and electric heating power, when the desired temperature is reached, First, turn off the steam valve and the electric heating power. After 2~3 minutes, turn off the mixer. After processing, put all the remaining condensed water in the pot and the clip. Then use 40 ~ 50 lye solution to fully clean the inner wall of the container, and rinse with clean water, for the empty pot without material (heat-absorbing medium) in the special pot, the steam valve and electric heating power supply cannot be turned on. Special attention should be paid to the use of steam pressure, which cannot exceed the working pressure.

The reaction department of the maintenance laboratory should always pay attention to the working conditions of the entire equipment and the reducer. If the lubricating oil of the reducer is insufficient, it should be replenished immediately. The electric heating medium oil should be replaced every six months. Safety valves, pressure gauges, pressure gauges, etc. Thermometers, distillers, electric heating rods, electrical instruments, etc. should be checked regularly, and if there is a malfunction, they should be replaced or repaired immediately, and warm water should be used when the equipment is not in use.
