Stirrer with stretch-in stirring vane arranged outside bottom of stirrer

Abstract

The invention discloses a stirrer with inserted stretch-in stirring vane arranged outside the bottom of the stirrer, which overcomes the defects in the prior art that inadequate reaction and poor mixing uniformity are caused by directly feeding raw materials, and an equipment structure is complicated by filling air directly, and the production cost is high. The stirrer with the stretch-in stirring vane arranged outside the bottom of the stirrer comprises a cylindrical reaction vessel, a flow guide column positioned in the reaction vessel, a round joint arranged at the lower end of the flow guide column, and an outflow hole formed at the upper end of a surface wall of the reaction vessel, wherein an inner cavity communicated with the flow guide column is arranged in the round joint, an arc-shaped flow guide hole is formed in a surface wall of the round joint, a tapered nozzle is also arranged at the upper end of the flow guide column, the stirring vane is arranged at the bottom of the reaction vessel, and an air intake hole is formed at the upper end of the flow guide column. The stirrer is simple in structure, low in cost and convenient to realize and operate, and therefore suitable for popularization and application.

Description

technical field [0001] The invention relates to a liquid mixing and processing equipment, in particular to a stirrer with an externally extending stirring blade at the bottom. Background technique [0002] With the development of the economy and the improvement of people's living standards, the requirements for water treatment in the fields of industrial ultrapure water preparation, wastewater treatment, drinking water and irrigation are getting higher and higher; as a new type of high-efficiency disinfectant, chlorine dioxide is widely used It is used in water treatment purification and disinfection in various fields. The traditional chlorine dioxide reaction device is produced by directly adding raw materials. The disadvantage of this method is that the reaction speed is slow and the mixing uniformity is not high. Based on this defect, people use to fill the reaction vessel with air and mix it. The method needs to rely on more complicated equipment, therefore, just inevit...

Problems solved by technology

The traditional chlorine dioxide reaction device is produced by directly adding raw materials. The disadvantage of this method is that the reaction speed is slow and the mixing uniformity is not high. Based on this defect, people use to fill the reaction vessel with air and mix it. The method needs to use more complex equipment, therefore, it will inevitably increase the production cost
