Rotating Venturi mixer with uniform plate

Abstract

The invention discloses a rotating Venturi mixer with a uniform plate. The rotating Venturi mixer comprises a front section, a rear section and a middle section which coaxially communicates the front section with the rear section, wherein the front section comprises a mainstream inflowing pipeline, a contraction section and a laryngeal front half section which are successively communicated; the laryngeal front half section is provided and communicated with an inputting fluid inputting pipeline, the rear section comprises a laryngeal rear half section, a diffusion section and a mainstream outflowing pipeline which are successively communicated, and the laryngeal rear half section is internally fixedly provided with the uniform plate which plays a stirring role along a diameter direction; the middle section is a sleeve, the laryngeal front half section is fixedly inserted into the sleeve, the laryngeal rear half section is fixedly inserted into the sleeve, the rear section is capable of rotating in the sleeve under the action of the external force, and the laryngeal front half section and the laryngeal rear half section are not contacted in the sleeve. The rotating Venturi mixer provided by the invention has the advantages that the purpose of intensifying mixing is achieved through the rotation of the rear section of the mixer and the uniform plate which plays a stirring role and is arranged on a laryngeal rear section, in addition, and the mixer achieves the purpose that disturbance intensity is regulated through controlling the rotating speed.

Description

technical field [0001] The invention relates to the technical field of Venturi mixers, in particular to a rotatable Venturi mixer with uniform plates. Background technique [0002] Venturi mixer is a gas-liquid or liquid-liquid mixing device widely used in engineering practice. The common Venturi mixer is a classic Venturi tube with an opening in the throat. The mainstream fluid flows through the classic Venturi tube, and the introduced fluid flows in through the opening, so that the two fluids will have a certain impact crushing effect due to pressure changes. And use the turbulence formed by two high-speed fluids to achieve the purpose of mixing. In the traditional Venturi introduction structure, due to the small disturbance intensity of the mixed fluid, it is easy to cause problems such as uneven mixing and low mixing efficiency. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the object of the present invention is t...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned problems in the prior art, the object of the present invention is to provide a rotatable Venturi mixer with a uniform plate, and at the same time, a uniform plate is arranged in the second half, which can enhance fluid disturbance in the Venturi tube, And it can control the rotation speed to adjust the disturbance intensity according to the needs, effectively avoid the phenomenon of uneven mixing, improve the mixing efficiency of the Venturi mixer, and make the Venturi mixer suitable for a wider range of flow rates of the incoming fluid and the mainstream fluid Proportion
