A jet jet driven blade agitator

Abstract

The invention discloses a jet injection drive type blade stirrer which comprises a support, wherein a bearing sleeve is fixedly arranged inside the support, a rotary hollow shaft is rotationally arranged inside the bearing sleeve, a bearing and a seal assembly are arranged between the rotary hollow shaft and the bearing sleeve, the lower end of the rotary hollow shaft is connected with a transverse water inflow joint, a water diversion block is mounted at the upper end of the rotary hollow shaft, the outer side of the water diversion block is connected with a plurality of spray bars arranged annularly, spray nozzles distributed in the radial direction are mounted on the spray bars, the directions of the spray nozzles are the same with the driving and rotating direction, and mixing blades are mounted on the spray bars. The application point of the driving force produced by the rotating motion of the blades and the resistance force of liquid are radially and symmetrically distributed along the blades, so as to enable the stress condition of the blades to be improved greatly. Therefore, the roots of the blades are fundamentally prevented from large stress which possibly causes fracture, and blades are fundamentally prevented from deformation caused by insufficient rigidity.

Description

technical field [0001] The invention mainly relates to the technical field of spraying technology and blade rotation stirring, and is applied to the mixing, stirring and anti-sedimentation of liquids in large containers (large diameter, large depth), and is specifically a jet-driven blade agitator. Background technique [0002] In various reaction kettles in the chemical industry, dense pools in the mining industry, anti-sedimentation in large storage tanks in the petroleum industry, and sewage treatment tanks in the environmental protection industry, the existing blade mixers are all mechanically driven. The basic working principle of its power transmission is: the prime mover (commonly used motor) drives the main shaft, the main shaft drives the blades to rotate, and the blades drive the liquid to flow, so as to realize the functions of solution stirring and mixing or anti-sedimentation. This principle of work must have corresponding requirements for the strength of the ma...

AI Technical Summary

Problems solved by technology

For general small containers and low-power agitators (suitable for small diameter and low liquid level depth), the strength and rigidity of the above components are easy to achieve, but for large diameter and large depth (such as mine beneficiation dense pools up to 20m in diameter, large oil storage The diameter of the tank can reach 80m, and the depth can reach 20m). The mixing and agitation of the solution in the container is difficult to achieve with the design and manufacture of the existing blade agitator, and the reliability of use is also greatly reduced. The blade deformation, jamming, and root breakage often occur , drive motor burnout and other accidents
