Multi-phase flow rotating jet mixing device for reinforcing grinding

Abstract

The invention discloses a multi-phase flow rotating jet mixing device for reinforcing grinding. The device comprises a mixing pipe, a rotating jet outer pipe, a rotating inner pipe and a mixing feeding cover. The two ends of the rotating jet outer pipe are fixedly connected with the mixing pipe and the mixing feeding cover; the rotating inner pipe is arranged in an inner cavity of the rotating jet outer pipe through a rotatable structure; a helical guide groove is formed in the wall of an inner cavity of the rotating jet outer pipe; two feeding inlets are formed in the mixing feeding cover; and one end of one feeding inlet and one end of the other feeding inlet communicate with the helical guide groove of the rotating jet outer pipe and the inner cavity of the rotating inner pipe respectively. The mixing pipe is of a Venturi tube structure, and the negative pressure section of the mixing pipe communicates with the feeding pipe. A negative pressure screw rod is fixedly arranged in the inner cavity of the rotating inner pipe. The multi-phase flow rotating jet mixing device can uniformly mix multi-phase grinding materials, and accordingly, the grinding reinforcement effect is improved.

Description

technical field [0001] The invention relates to an intensified grinding processing mixing device, in particular to a multiphase flow rotating jet mixing device for intensified grinding processing. Background technique [0002] Intensified grinding process is a kind of anti-fatigue, anti-corrosion, anti-wear metal material surface strengthening processing method based on composite processing method. Its principle is to mix steel balls, grinding powder, grinding liquid and compressed gas and spray them on the surface of the workpiece to be processed. , the oblique, high-speed mixed jet stream will produce random and equal probability collisions (plastic processing, resulting in residual compressive stress) and micro-cutting (grinding) on ​​the surface of the processed workpiece, so that the metal workpiece can obtain a lower surface roughness and consistency. (shape control), and at the same time obtain the "oil bag" that is beneficial to lubrication and high performance of lo...

AI Technical Summary

Problems solved by technology

The single tangential feeding and rotating axial speed is small, and the formed rotating jet is easy to diffuse and does not meet the processing requirements; while the single guiding element may make the maximum axial speed eccentric, reducing the processing accuracy and processing accuracy. quality

Therefore, the rotating jet produced by the above method is not suitable for intensive grinding
