System and method for feeding and conveying high-concentration solid powder particle suspension

Abstract

The invention discloses a system and a method for feeding and conveying high-concentration solid powder particle suspension. The system comprises a material mixing device, a material feeding device, an inclined pipe, a three-way valve, a water outlet channel and an air channel, wherein the material mixing device is used for forming the high-concentration solid powder particle suspension; the material feeding device is required to feed the high-concentration solid powder particle suspension; the inclined pipe is used for leading the high-concentration solid powder particle suspension out of the material mixing device; the water outlet channel is used for leading the high-concentration solid powder particle suspension to the material feeding device; the air channel is used for introducing air or liquid for cleaning; one end of the inclined pipe is connected with an outlet of the material mixing device, is inclined upwards and forms an acute angle with the material mixing device; the high-concentration solid powder particle suspension flows out of the outlet of the material mixing device; and the other end of the inclined pipe, the water outlet channel and the air channel are connected with three ports of the three-way valve respectively. By optimized type selection and arrangement of pipelines, the valve and a conveying pump, the problem of deposition of a system for feeding and conveying the high-concentration solid powder particle suspension is solved.

Description

technical field [0001] The invention relates to a high-concentration solid powder particle suspension dosing and delivery system and method. Background technique [0002] For solid powder particles with a density greater than that of the dispersed phase (liquid item), there are many ways to add them to the liquid. For example, the powder is directly added to the liquid; the powder is first mixed with a small amount of liquid to form a high-concentration suspension, and then Add the suspension to the liquid. [0003] If the powder is directly added to the liquid, there will be many problems: 1. The powder is not easy to transport and measure. 2. It is not easy to disperse without stirring in the liquid, and it is easy to agglomerate. 3. The powder is easy to fly. The above-mentioned problems will not occur if the powder is made into a high-concentration suspension and then added. [0004] But high-concentration suspensions do not flow without stirring. The solid powder p...
