Abstract

The invention relates to a stirring device which comprises a stirring container and a driving unit connected with the stirring container, wherein, a stirring paddle is installed in the stirring container, a drive shaft is arranged on the driving unit, a shaft coupling, a bearing, a sealing means and the stirring paddle are sequentially connected with the drive shaft from top to bottom, the sealing means is externally connected with an outboard gas source which is connected to a place where the sealing means and the drive shaft joins through a pipeline, and a through hole is provided on the outer wall of the driving unit for letting in the pipeline of the outboard gas source. According to the invention, the sealing means is externally connected with the outboard gas source, gas is used for sealing, powder is isolated by gas pressure, and the bearing rotating at a high speed is cooled; therefore, the bearing is protected, work environment is improved, and leakage of oil stains is prevented, achieving the effect of cleanness.

Description

technical field [0001] The invention relates to a stirring device. Background technique [0002] Reasons for the failure of the stirring device: sealing device 69%, fixed coupling 9%, bearing 10%, hydraulic system 3%, coupler 2%, other 7%. Therefore, the mixing device is generally equipped with a mechanical seal. The functions of the mechanical seal: 1. Improve mechanical efficiency and reduce energy consumption; 2. Save raw materials; 3. Improve machine reliability; 4. Safety and environmental protection. In order to lubricate and cool the sealing end face, the hydrodynamic double-end face seal is often selected as the seal for the kettle, and lubricating oil or well-lubricated liquid is passed between the two seals for lubrication and cooling. [0003] The bearings of the stirring device are generally lubricated with grease or lubricating oil to ensure the normal use of the bearings, but in the case of solids, especially when the powder is sealed, the solids are easy to l...
