Pulp tank agitator

Abstract

The invention discloses a pulp tank agitator. The pulp tank agitator comprises an agitating shaft (1), a second vane wheel (3) is fixedly arranged at the bottom end of the agitating shaft (1), and a first vane wheel (2) fixed on the agitating shaft (1) is arranged over the second vane wheel (3); the water attaining surfaces of the propeller surfaces of first vanes (21) adopted by the first vane wheel (2) bend downwards, and the tails of the first vanes (21) are provided with first flow stabilizing rings(211) which bend downwards; the water attaining surfaces of the propeller surfaces of second vanes (31) adopted by the second vane wheel (3) bend downwards, the tails of the second vanes (31) are provided with upward-bending sections (311) to push materials to move downwards in the axial direction of the agitating shaft (1) and move downwards and outwards in the radial direction of the agitating shaft (1), and meanwhile the outermost ends of the upward-bending sections (311) are provided with upward-bending second flow stabilizing rings (3111). According to the pulp tank agitator, agitating is stable and efficient, part replacing is convenient, the angle of the vanes can be regulated, and therefore the pulp tank agitator is suitable for use and popularization.

Description

technical field [0001] The invention relates to the technical field of agitation, in particular to a slurry tank agitator with stable and efficient agitation, convenient replacement of parts and the ability to adjust the blade angle. Background technique [0002] With the continuous development of industry, it is required to increase the size and high solid content of the pulp mixing tank to improve production efficiency. However, the existing flat paddle stirring, narrow paddle stirring, and simple folding paddle stirring have small displacement, high power consumption, and poor stability. , The stirring reaction is not uniform, and it is easy to sink to the bottom, which brings immeasurable losses such as parking and production stoppage to users. [0003] The non-efficient design of the agitator blades increases the power of the user's motor and increases the operating cost; the unstable design of the agitator blades causes the agitator shaft to shake, shortens the servic...

Problems solved by technology

[0002] With the continuous development of industry, it is required to increase the size and high solid content of the pulp mixing tank to improve production efficiency. However, the existing flat paddle stirring, narrow paddle stirring, and simple folding paddle stirring have small displacement, high power consumption, and poor stability. , Stirring reaction is not uniform, easy to sink to the bottom, bringing immeasurable losses to users such as parking and production stoppage

[0003] The non-efficient design of the agitator blades increases the power of the user's motor and increases the operating cost; the unstable design of the agitator blades causes the agitator shaft to shake, shortens the service life of the inner bearing of the agitator drive, and increases the maintenance cost of the user

Generally, a set of agitators is only for one process, and the versatility is not strong. Some users need to purchase a new set of agitators due to production needs to adjust the process and change the types of products produced, resulting in low equipment utilization.

And the agitator blades are generally welded with the agitator shaft. As the service life increases, the agitator blades are corroded and eroded, and the user needs to replace spare parts. Often because the agitator blades are welded to the agitator shaft, the user is often forced to replace the agitator shaft. Let users spend money and effort
