The agitation reactor’s transmission effectively includes a reducer, agitator shaft, a motor and a coupling. When used, the kettle drive is generally set on the top of the reaction vessel (upper head). Style layout. The motor is reduced by the speed reducer to the stirring speed required by the process. After the coupling, the stirring shaft is driven to rotate, thereby driving the mixer to rotate.
The speed reducer and the electric motor of the stirred reactor are used together, and a machine base is set under the speed reducer, which is mainly installed on the head of the reactor, considering that the transmission device and the shaft sealing device must maintain a certain degree of concentricity during installation. As well as the convenience of loading and unloading, often a base is welded on the head. The entire transmission is mounted on the base together with the base and the shaft seal.
The design content of the agitation reactor’s transmission mainly includes the selection of the motor, reducer and coupling. The majority of the motor used in the equipment is used with the reducer. Only when the agitation speed is high, the speed reducer is not used. Directly stir the shaft. The general motor and reducer are matched and supplied, and a matching motor can be selected according to the selected speed reducer during design.
The types of reducers commonly used in stirred reactors include gear reducers, V-belt reducers, worm gear reducers, harmonic reducers, and cycloidal pin gear planetary reducers. When selecting a retarder, its use characteristics should be considered, such as the reduction ratio range. Output shaft speed range, power range, and efficiency parameters. When the standard speed reducer is selected, the matching motors, couplings, and bases are all standard models and are supplied as an accessory.
The magnetic coupling in the stirring reactor drives the outer magnetic steel body to rotate through a motor or a decelerator, and when used, it will magnetically actuate the rotation of the inner magnetic steel body in the sealing cover, the shaft and the stirrer of the inner magnetic steel body. The shaft is connected as one and reaches the stirring material, and the graphite gasket between the inner magnetic steel sealing cover and the kettle body is pressed by bolts to achieve complete isolation from the outside, thereby realizing no leakage under high temperature and high pressure.
Stirred reactors are especially suitable for explosive and highly toxic, flammable, and valuable media used in pilot and large-scale production. They can be stirred under high temperature, high pressure, vacuum conditions, etc., thereby thoroughly solving the mechanical seals and fillers. Sealing can not overcome the leakage problem, to ensure that the environment and personal integrity.
