Adaptive proportional liquid mixing device

Abstract

The invention discloses an adaptive proportional liquid mixing device comprising a manifold, a main pipeline and a branch pipeline, wherein the main pipeline and the branch pipeline are branched from the manifold and connected in parallel; a mixer is arranged on the branch pipeline; a V-shaped pipe is arranged on the main pipeline; and a floater capable of freely floating in fluid is arranged in a flow channel of the V-shaped pipe. The adaptive compensation proportional mixing device disclosed by the invention adopts a simple mechanical proportional mixing structure, errors in flow distribution / proportion of mixture caused by variations in pressure and flow in each pipeline are dynamically compensated by additionally arranging a floating pressure trimming device, and the accuracy of proportion of mixture of the system is greatly improved under the condition of maintaining the advantages of simple structure, convenience in use and the like of the system.

Description

Liquid self-adaptive proportional mixing device Technical field The invention relates to the field of machinery, in particular to a liquid self-adaptive proportional mixing device for proportional mixing of liquids. Background technique In many fields such as water treatment, food and beverage, medical treatment, fire protection, etc., it is necessary to mix high-concentration liquid medicines and configure them into low-concentration solutions for use. The following methods are usually used: 1. At present, the most widely used method is to use a metering pump to pump high-concentration liquid medicine quantitatively, and to control the flow rate of the metering pump by detecting the relevant characteristics of the product solution to achieve the concentration control of the product solution. This more popular method can better control the mixing concentration of the liquid medicine, but because it is through the detection feedback control method, the control delay is inevita...

AI Technical Summary

Problems solved by technology

The ring pump type proportional mixer requires a corrosion-resistant high-precision pump, and the operation is complicated, and the system startup preparation time is long

The pressure proportional mixer adopts a mechanical structure, but there is no pressure or flow compensation mechanism. When the outlet pressure or flow changes, the mixing ratio will be unstable, which will affect the fire protection effect and waste foam liquid.
