The paddle mixer has the simplest structure. The blades are made of flat steel and welded or bolted to the hub. The number of blades is
There are two, three, or four blades. The leaf types can be divided into two types: straight leaves and folded leaves.
Can be divided into flat paddle agitator and oblique paddle agitator. Flat paddle agitator produces radial force, oblique paddle agitator
The axial force is generated. The paddle stirrer is suitable for stirring low-viscosity liquids, suspensions and dissolving liquids.
The mixing stage in the coagulation process for water supply and drainage treatment, when raw water flows through the coagulant or coagulant liquid
When the pool is closed, a flow cycle is generated under the discharge of the mixer, so that the coagulation agent and water are quickly and fully mixed to achieve
To the coagulation process requirements.
1. Simple structure, reliable operation, no clogging and easy maintenance.
2. It can reach a certain stirring intensity within the required mixing time, meet the requirements of fast, uniform and sufficient mixing speed, and has small head loss, and can adapt to changes in water volume, suitable for water plants with various water volumes.
Construction and working process
As shown in the figure, the JBJ type paddle mixer is composed of a stirring shaft, a paddle blade, a machine base and a driving device. When raw water and coagulant or coagulant liquid flow through the mixing tank, it flows under the discharge of the mixer Circulation to make the coagulant and water quickly and fully mixed to meet the requirements of the coagulation process.
