Power output equipment, hydraulic stirrer, high-pressure reaction kettle including power output equipment and hydraulic stirrer, and system

Abstract

The invention provides power output equipment. The power output equipment comprises a hydraulic motor (3), a shielding cover (24), a sealing element (8) and an incompressible fluid (23), wherein the hydraulic motor is provided with a motor coupler (6), a power output shaft (7) and hydraulic oil pipes (4, 5); a support sleeve (10) is arranged at an open end of the shielding cover (24); the hydraulic motor (3) is accommodated in the shielding cover (24); the other end of the power output shaft (7) passes through the support sleeve (10); the sealing oil pipes (4 and 5) pass through the shieldingcover (24), and are sued for connecting a hydraulic station (22); the sealing element (8) is arranged between the support sleeve (10) and the power output shaft (7), so that an area, in which the hydraulic motor is accommodated, in the shielding cover (24) forms an enclosed space; the incompressible fluid (23) is located in the enclosed space; the enclosed space is fully filled with the incompressible fluid. The equipment provided by the invention is particularly suitable for high-pressure reaction kettles.

Description

technical field [0001] The application belongs to the field of mechanical equipment, and in particular relates to a power output device, a hydraulic agitator, a high-pressure reactor containing the same, and a reactor system including the hydraulic agitator. Background technique [0002] At present, in the high-pressure reactor or the reactor of special medium used in the laboratory and industrial production, in order to ensure the airtightness, a magnetic coupling-driven stirrer (magnetic stirrer) is used, (such as figure 1 As shown in ) the agitator is driven by a drive motor through a reducer to drive a hollow cylindrical outer magnet to rotate, and the inner magnet is driven to rotate by magnetic force. The inner magnet is connected to the stirring shaft to make the stirring shaft rotate. The pressure shield is isolated to achieve static sealing of the stirring drive. The magnetic force line coupling between the power drive of the magnetic stirrer and the stirring shaft...

Problems solved by technology

However, this sealing method still does not achieve the purpose of isolating the atmosphere in the sealed cover from the reactor, which makes the gas reactants in the reactor possibly enter the sealed cover and corrode the equipment therein

This is especially true in the case of high-pressure reactors. Since the pressure of the reactor can be transmitted to the sealed cover through the support bearing, as the pressure of the reactor rises, the raw material gas, mixed steam, and raw material dust in the reactor will flow up to the In the sealing cover, if there is corrosive gas, it will cause corrosion to the components in the sealing cover. Since there is no cooling measure, the heat of reaction will be transmitted to the bearing through the stirring shaft and steam to accelerate the damage of the bearing. Excessive temperature will also make the hydraulic motor The premature aging of the rubber sealing element shortens the service life; the stirring shaft shown in the attached drawing of the patent has no lower support, and the swing of the stirring shaft is borne by a bearing on the support, which will accelerate the damage of the bearing

Therefore, this equipment is not suitable for high-pressure reactors
