Stirrer and equipment with stirrer

Abstract

The invention discloses a stirrer and industrial equipment with the stirrer. The stirrer comprises a motor, a first cover, a second cover, a rotating shaft and blades, wherein the motor comprises a stator assembly and a rotor assembly, wherein the stator assembly comprises an annular stator and a fully-sealed hood annularly surrounding the stator, the rotor assembly is surrounded with the stator assembly, a gap is formed between the rotor assembly and the stator assembly, and the rotor assembly comprises a rotor and a fully-sealed hood surrounding the rotor; the first cover seals the first endof the stator assembly, the second cover seals the second end opposite to the first end of the stator assembly, and the stator assembly, the first cover and the second cover together define the innerspace of the stirrer; the rotating shaft is provided with a first end and a second end which are opposite, the first end of the rotating shaft is fixed on the hood of the rotor assembly, the rotatingshaft extends and passes through an opening in the second cover, and the second end of the rotating shaft extends out of the inner space; and the blades are fixed at the second end of the rotating shaft. The stirrer disclosed by the invention has better working stability and lowered maintenance cost.

Description

technical field [0001] The invention relates to an agitator, in particular to an agitator suitable for agitating medium that is not allowed to leak in the industrial fields of petroleum, chemical industry, food, textile, etc. The invention also relates to an industrial plant with a stirrer. Background technique [0002] In industrial fields such as petroleum, chemical, food, textile, etc., it is often necessary to stir the medium. A blender is required for this. Some media to be stirred may be hot or toxic, or leakage may not be tolerated for other reasons. In this case, it is necessary to ensure the tightness between the mixer and the industrial equipment. For example, in the limestone-gypsum wet flue gas desulfurization process, it is necessary to stir the slurry in the desulfurization tower with the agitator installed at the bottom of the desulfurization tower to enhance the diffusion of oxidizing air and promote the separation of sulfite and bisulfite. The forced oxi...
