Three-stage mixing device with hydrodynamic self-control

Abstract

The invention provides a hydrodynamic self-controlled three-stage mixing device, which comprises three-stage mixing structures connected in sequence, the first-stage mixing structure includes a Venturi mixer, and the second-stage mixing structure includes a discharge material connected to the Venturi mixer The three-stage mixing structure includes a stirring tank connected to the discharge port of the static mixer, a two-layer stirring paddle set in the stirring tank, a floating ball valve set in the stirring tank and The motor that drives the two layers of the stirring paddle, the floating ball valve is set corresponding to the feeding port of the stirring tank, so that when the liquid level rises to the upper limit position, the feeding port of the stirring tank is blocked, and the material of the stirring tank is discharged. The port is set lower than the feed port of the stirring tank. The fluid mechanics self-controlled three-stage mixing device has the advantages of scientific design, automatic continuous production, stable mixing ratio, low equipment investment, and low operation and maintenance cost.

Description

technical field [0001] The invention relates to a fluid mixing device, in particular to a fluid mechanics self-controlled three-stage mixing device. Background technique [0002] There are generally two extreme situations in the chemical, food, beverage and other industries involving the mixing of high-concentration and low-concentration liquids: one is that the level of automation is too low and requires a lot of manual participation; the other is that the level of automation is high and requires A large amount of initial investment, high operation and maintenance costs. [0003] The low degree of automation of the mixing of two liquids is generally seen in small chemical, food, beverage and other industries. Manual control or semi-automatic control is often used. Operators watch the testing instruments on site, record real-time data, and make manual adjustments to complete the process. Manual monitoring operation greatly reduces production efficiency, and manual operation...

AI Technical Summary

Problems solved by technology

However, the advanced control system greatly increases the initial investment cost of the production line, and also requires a lot of investment in the later operation, maintenance, repair, etc.

This type of automation mode is only suitable for large-scale high-end enterprises, and it is a very heavy burden for small and medium-sized enterprises, which is not conducive to the technological transformation of small and medium-sized enterprises

[0005] In addition, the traditional industry basically adopts an intermittent production process, that is, large-scale storage tanks are used for quantitative compounding and mixing. This process has problems such as intermittent production resulting in unstable batch products and inconvenient adjustment of production load.
