Axial ventilating type high-efficiency stirrer

Abstract

The invention discloses an axial ventilating type high-efficiency stirrer. The lower end of a machine base shaft is connected with a stirring rod through a conical centering and coupling device. An upper stirring impeller and a lower stirring impeller are arranged on the stirring rod. Stirring blades of the upper stirring impeller and stirring blades of the lower stirring impellers are symmetrically installed in the vertical direction. Each stirring blade comprises a base plate and a turning plate, wherein the base plate and the turning plate are connected to form an included angle of 100 degrees to 170 degrees, and a tilt angle of 10 degrees to 70 degrees is formed between the base plate and the horizontal plane. An air nozzle is fixed to the bottom end of the stirring rod which is a hollow pipe. An air guide pipe is arranged in the stirring rod. The upper end of the air guide pipe penetrates through a machine base cushion plate and is communicated with an air inlet connector. The lower end of the air guide pipe is communicated with the air nozzle. Air outlets are evenly formed in the air nozzle. A tilt angle of alpha degrees is formed between the air outlets in the circumference of the air nozzle and the diameter line, wherein alpha ranges from 5 degrees to 45 degrees. The traditional mode that air is only pressed in from the wall circumference of a container through a pipeline is changed, the defect of air shortage in the middle area of the container is overcome, the chemical combination effect is made better, and the quality and efficiency of wet metallurgy are greatly improved.

Description

technical field [0001] The invention relates to the technical field of stirring machinery, in particular to a shaft-ventilated high-efficiency mixer. Background technique [0002] It is a traditional technology in the hydrometallurgy industry to mix the immiscible liquid or prepare a uniform suspension through the rotation of the mixer in the container, and it is also a necessary process. 4-6 high-pressure ventilation pipes are evenly distributed on the top. However, the diameter of the container in the hydrometallurgical industry is relatively large. When air is injected along the container wall, it is difficult for the air to reach the central area of ​​the container, which affects the compounding (mixing) effect and reduces the quality of hydrometallurgical processing. [0003] Through patent search, there are the following known prior art solutions: [0004] Patent 1: [0005] Application number: 201510535476.X, application date: 2015.08.26, application publication da...
