Blending device and method for multiple granular materials

Abstract

The invention relates to a blending device and a method for multiple granular materials. The blending device and the method solve such problems as much consumed labour and time and lower efficiency in artificial blending, material damage and material blending influence easily caused by blending of a stirrer in the prior art. The blending device comprises an uniformly dividing part and a mixing part, wherein the uniformly dividing part comprises a plurality of rows of cylinders which are progressively increased in multiples and pipelines; the pipelines extend to the upper side of the cylinders and are divided into two branch pipelines; the two branch pipelines respectively bypass two sides of the cylinders, so as to extend to the upper side of the next row of cylinders until extending to the last row of cylinders after carrying out repeated operations; the mixing part is a mixing hopper arranged below the uniformly dividing part. The blending device has the advantages of reducing an influence of artificial operation to mixing uniformity of the granular materials, improving blending efficiency and improving material mixing uniformity, so that materials are randomly uniformly distributed in space, as well as can be randomly differently distributed in time.

Description

technical field [0001] The invention relates to the technical field of material mixing, in particular to a device and method for mixing various granular materials with high efficiency, little damage and good uniformity. Background technique [0002] In the LED packaging industry, plastic injection molding industry, food processing industry, and metallurgical industry, there are operations of mixing two or more granular materials. At present, the methods and equipment often used for mixing granular materials include manual mixing and mechanical mixing. However, there are defects in these methods, such as manual mixing, which requires a lot of manpower and time, and the efficiency is low, and the uniformity of material mixing is greatly affected by human operation; It is more violent, it is easy to cause damage to the material, and it is easy to produce a dead angle of mixing inside the mixing cylinder, which will also affect the uniformity of material mixing. [0003] For e...
