Abstract

A high-gravity rotating bed device, including a motor, a rotor and a housing. The rotor and the motor are entirely arranged within the housing. A load-bearing plate is provided within the housing. The load-bearing plate divides the housing into a reaction chamber and a balance chamber. The motor is arranged within the balance chamber. A transmission shaft of the motor passes through the load-bearing plate and is fixedly connected to the rotor arranged within the reaction chamber. A gas inlet, a gas outlet, a liquid inlet and a liquid outlet are arranged on the housing. An externally communicating pipeline is arranged on the balance chamber. Also disclosed is an application of the present high-gravity rotating bed device under high-pressure conditions in operations such as mixing, transferring and reacting.

First claim

a bearing plate is arranged in the housing, and the bearing plate divides the housing into a reaction chamber and a balance chamber;
the motor is arranged in the balance chamber, and a transmission shaft of the motor passes through the bearing plate to be fixedly connected to the rotor arranged in the reaction chamber;
a gas inlet, a gas outlet, a liquid inlet and a liquid outlet are formed on the housing; and
a pipeline communicated with the outside is arranged on the balance chamber.

2. The motor built-in high-gravity rotating bed device according to claim 1 , wherein
the reaction chamber is positioned above the bearing plate, and the balance chamber is positioned below the bearing plate; the gas inlet is formed on a side wall of the reaction chamber, the gas outlet extends out of the reaction chamber from a center of the rotor, and the liquid inlet is connected to a liquid distributor at a peripheral position of a hollow part of the rotor; and the liquid outlet extends out of the reaction chamber from an upper opening of the bearing plate.

3. The motor built-in high-gravity rotating bed device according to claim 2 , wherein a pipeline is arranged at a lower end of the motor to be communicated with the reaction chamber.

4. The motor built-in high-gravity rotating bed device according to claim 1 , wherein
the reaction chamber is positioned below the bearing plate, and the balance chamber is positioned above the bearing plate; the gas inlet is formed on a side wall of the reaction chamber, the gas outlet extends out of the reaction chamber from a center of the rotor, and the liquid inlet is connected to the liquid distributor at the peripheral position of a hollow part of the rotor; and the liquid outlet is formed at a bottom of the reaction chamber.

5. The motor built-in high-gravity rotating bed device according to claim 1 wherein the motor is a shielding motor.

6. Application of the device according to claim 1 in operation processes of mixing, transfer and reaction in a high-pressure environment, wherein a rotating speed of the motor is 20 to 3,000 rpm, an operation temperature in the reaction chamber is 40 to 400° C., and an operation pressure in the reaction chamber is 0.05 to 50 MPa.

7. The application according to claim 6 , wherein when material reaction is performed in the reaction chamber, protective gas is introduced into the balance chamber through an external pipeline, so that the pressures in the reaction chamber and the balance chamber are balanced.
