Electromotor combined with pressure vessel

Abstract

The invention relates to an electromotor combined with a pressure vessel. The electromotor comprises an electromotor shell, a rotating shaft, a stator, a rotor, a shaft extension end cover, a non-shaft extension end cover, a terminal box, a terminal box cover, a terminal board and electric connection components, wherein the terminal board and the electric connection components are arranged in the terminal box, and connection components are arranged at the two ends of the electromotor shell. The electromotor is characterized in that a bearing hole in the non-extension shaft end cover does not penetrate through the outer end face, a shaft sleeve is fixed to the outer end face of the shaft extension end cover in a sealed mode, a flange is fixed to the other end of the shaft sleeve in a sealed mode, the shaft extension end of the rotating shaft penetrates through the shaft extension end cover and the shaft sleeve and extends out of the flange, sealing elements are arranged between the connection components of the shaft extension end cover, the non-shaft extension end cover and the electromotor shell, and a sealing element is arranged between the terminal board and the terminal box. The rotating shaft of the electromotor is used as the rotating shaft of a stirrer of the pressure vessel, the pressure in the pressure vessel shifts into the electromotor through the shaft sleeve, and the problem that the pressure vessel is difficult to seal is well solved through the good sealing performance of the electromotor shell and all the components. The electromotor is suitable for high-pressure operation environments.

Description

technical field [0001] The invention relates to an electric motor structurally connected to a mechanical load, especially an electric motor used in conjunction with a pressure vessel. Background technique [0002] We know that the production process of rubber, chemical, textile and other industries needs to be carried out in a pressure environment, so pressure vessels are widely used, and most production processes require a motor to drive the agitator in the pressure vessel to achieve mixing and mixing. At present, a coupling is usually used for power transmission between the agitator shaft and the motor shaft of the pressure vessel, but the degree of freedom of rotation between the coupling and the pressure vessel shell makes it difficult to seal the pressure vessel, and a complex dynamic sealing device must be used Realize the isolation of the high-pressure medium from the outside of the pressure vessel. This kind of dynamic sealing device has a complex structure and high ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortage of the prior art that the pressure vessel is difficult to seal due to the use of a coupling between the agitator and the motor of the pressure vessel, the present invention provides a motor combined with a pressure vessel with reasonable structure design, reliable use and high sealing performance
