The magnetic drive reactor primarily consists of a heating furnace, reactor vessel body, vessel lid, and magnetic stirrer.
The heating furnace is designed to heat the reactor vessel body. It features a cylindrical outer shell containing a cylindrical silicon furnace core with embedded heating resistance wires, offering efficient heat transfer and rapid heating capabilities. A socket is located on the lower side of the furnace body, allowing it to be connected to the control unit via a power cable.
The reactor vessel body is the chamber where the material reaction takes place; it is constructed from metals such as stainless steel. The vessel body connects to the flange via threads. Sealing between the vessel body and the lid is achieved through a metal-to-metal contact design-specifically, a line seal formed between an arc surface and a conical surface-relying on high-precision machining and the tightening force of the main bolts to ensure a secure seal.
The vessel lid is a key component of the magnetic drive reactor and is made of 1Cr18Ni9Ti stainless steel. It is equipped with various devices-including a magnetic stirrer, pressure gauge, rupture disc, gas valve, sampling valve, and cooling coil-to facilitate real-time monitoring of the reaction process and adjustment of material composition, ratios, temperature, and pressure, thereby ensuring safe operation.
The magnetic stirrer is a permanent magnet coupling device composed of inner and outer annular magnets separated by a pressure-bearing isolation sleeve. A servo motor transmits stirring torque through the magnetic coupling between the inner and outer magnets. A speed-sensing element is installed inside the isolation sleeve; as the stirrer and inner magnet rotate, electronic components generate an induction signal that is transmitted to the control unit to display the stirrer's operating speed.
