Magnetic reaction kettleMainly composed of heating furnace, kettle body, kettle cover, magnetic stirrer and other parts
(1) Heating furnace, used to heat the reactor body, with a cylindrical furnace body containing a cylindrical silicon core. The heating resistance wire is threaded through it, which has the characteristics of good heat transfer effect and fast heating. The lower side of the furnace body is equipped with a socket, which is connected to the control instrument with a cable when in use.
(2) The reactor body is mainly used for material reaction, and the material is made of TA2. The reactor body and flange are connected by threads. The sealing between the reactor body and the lid is achieved by using non heat sheet circular arc and conical line sealing. With high processing accuracy and the tightening force of the main bolt, the sealing effect is achieved.
(3) The kettle cover is the main component of the magnetic reaction kettle, made of 1Cr18Ni9Ti material. The kettle cover is equipped with magnetic stirrer, pressure gauge, blasting valve, air valve, sampling valve, cooling coil and other devices, which are easy to grasp the reaction situation of the materials in the magnetic reaction kettle at any time, adjust the composition, proportion, temperature and pressure of the materials in the magnetic reaction kettle, and ensure the safe operation of the magnetic reaction kettle.
(4) Magnetic stirrer, a permanent magnet coupling device, consists of inner and outer annular magnetic steel, with a pressure bearing spacer in the middle. The stirring torque is transmitted by a servo motor through the magnetic force of the inner and outer magnetic steel. The spacer is equipped with a speed measuring element. When the stirrer rotates with the inner magnetic steel, an induction signal is generated through electronic components and transmitted to the control instrument, displaying the working speed of the magnetic stirrer.
Magnetic reaction kettleSafety and protection devices:
A、 A safety valve or safety blasting device can be installed on the kettle cover as needed. When the pressure inside the kettle exceeds the specified pressure, the safety valve will automatically open or the blasting disc will burst, reducing the pressure on its own to ensure the safety of the equipment. It should be noted that the safety valve is not allowed to be used without calibration, and lead sealing should be added after calibration. If blasting discs are used, they must have a production certificate before they can be used.
B、 Both the kettle cover and the kettle body flange are equipped with lining interlayer exhaust holes. If there is any leakage, first search for it here and take timely measures.
C、 The YB series explosion-proof three-phase asynchronous motor is selected for the magnetic stirring reactor to protect the safe operation of the motor under flammable and explosive conditions.
From the above introduction, it can be found that the heating method of magnetic reaction kettle is more flexible. Flexible customization can be made according to the user's choice. In the following article, we will briefly introduce the heating method of the enamel reaction kettle.
