Agitating kettle with mechanical seal convenient to change

Abstract

The invention provides an agitating kettle with a mechanical seal convenient to change, which belongs to the technical field of machinery and solves the technical problem of inconvenient replacement of existing mechanical seals. The agitating kettle comprises a kettle body, wherein a machine frame is arranged on the kettle body, a speed reducer is arranged on the machine frame, a stirring shaft isarranged on the kettle body in a penetrating manner, and a gap with width larger than the thickness of the mechanical seal is formed between the end part of the stirring shaft and the output end of the speed reducer, a connecting member is arranged between the end part of the stirring shaft and the output end of the speed reducer, a first clamping portion and a second clamping portion, which aredetachably connected with each other, are arranged at each end of the connecting member, and the first clamping portion and the second clamping portion at one end of the connecting member radially clamp the end part of the stirring shaft and form axial and radial clamping connection. In the process of taking out the mechanical seal, the speed reducer and the like do not need to be disassembled byvirtue of the connecting member, so that the power transmission can be stable while the mechanical seal is easily disassembled, and the connection position does not need to be periodically changed.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a stirring tank which is convenient for replacing a mechanical seal. Background technique [0002] Industrially, kettle bodies are needed in various processing fields, which can be reaction kettles, stirred tanks, etc. according to different uses. Usually, there is a stirring paddle inside the stirring tank, and the external motor drives the stirring paddle to stir, and the motor is usually connected to the stirring paddle through a coupling, and the stirring paddle runs through the kettle body, and a corresponding valve is set between the stirring paddle and the penetrating part of the kettle body. Mechanical seals seal the connection points. [0003] my country's patent application literature (notification number: CN206262396U; announcement date: 2047.6.20) discloses a side-entry stirring device, including a driving device, a tank body, a stirring shaft is arranged on the tank body, and ...
