Hydrodynamic cavitation strengthening equipment

Abstract

The invention discloses hydrodynamic cavitation strengthening equipment, which comprises a base bracket, a flange set and a motor, wherein the flange set and the motor are arranged on the base bracket, a cavity is formed by two flanges of the flange set, sealing rings are arranged in the centers of the two flanges respectively, a blade set is arranged between the two sealing rings in a clamped mode, an inlet pipe is arranged on the flange far away from the motor, an outlet pipe is arranged on the flange close to the motor, and the shaft of the blade set penetrates through the two sealing ringsand is fixedly connected with the shaft of the motor through a coupler so as to be driven by the motor to rotate. According to the invention, a liquid in the cavity can be subjected to shearing, rubbing, centrifugation, turbulence and the like through rotation and cutting of the blade set to drive all the liquid in the cavity to flow, so that the flow speed of the liquid in the cavity is promotedto be greatly changed, the pressure of the liquid in the cavity is promoted to be changed, the cavitation process is intensified, and the cavitation generation efficiency and the cavitation effect utilization efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of cavitation, in particular to hydraulic cavitation strengthening equipment. Background technique [0002] Cavitation is a process of forming vapor cavitation in the low-pressure area of ​​the liquid flow field. When the internal pressure of the liquid drops below the saturated vapor pressure, the bubbles formed in the cavitation process begin to appear and grow. As time goes on, the cavitation Dilation, growth, compression and collapse. This process is explosive, less than six thousandths of a second, and the cavitation can release huge energy at the moment of rapid collapse, instantly generating local high temperature (1900-5000K) and high pressure (up to 140MPa-170Mpa), and the generation speed is about 110m / s micro-jet with powerful impact, thus causing a series of phenomena such as cavitation, air noise, vibration and luminescence. These effects caused by cavitation are usually called cavitation effec...

AI Technical Summary

Problems solved by technology

Except for hydrodynamic cavitation, the other three are difficult to be efficiently applied in large-scale industrial production due to low input energy and limited action space.

[0004] The current geometric structure of the system changes the flow rate of the liquid through the setting of the spiral parts or the vibration of the vibrating reed, thereby generating cavitation, but the above structure can only drive the local liquid, and the change of the flow rate of the liquid is small, and the efficiency of cavitation is poor. , leading to poor utilization efficiency of cavitation effect
