Problems solved by technology

However, these devices are all designed for a certain material (grain or powder). When the properties of the material change or fluctuate greatly, they cannot be transported, which is also one of the reasons for the system to be blocked.

Abstract

The invention relates to an airflow conveying device for both powder and pellets, comprising a compressor (1), a gas management system (2), an upstream silo for powder (3), a downstream silo (5), and a fan (17) , the second rotary valve (13), the 11th reversing valve (1811), the first filter (8) connected to the upstream powder material bin (3), the second filter (12) connected to the downstream bin ; Also includes: at least one upstream silo (40, 41, 42) for granular materials, an elutriator (6), a cyclone separator (7), a first rotary valve (11), a The multi-way reversing valve (9) of the feed upstream silo (3) or the pellet upstream feed bin (40, 41, 42), a group of reversing valves; the powder and pellet conveying are integrated in a set of devices, The range of conveying materials is greatly increased, and the average particle size distribution range of materials can reach 5-6000 μm, basically including all solid materials currently suitable for air conveying.

Description

technical field [0001] The invention relates to an airflow conveying device, in particular to an airflow conveying device suitable for solid powder or granular materials in petrochemical, metallurgy, food, medicine and other industries. Background technique [0002] The solid material is distributed according to the particle size. The collection of particles with a particle size of less than 0.05-0.1mm is called powder, and the collection of particles with a particle size larger than 1mm is called pellets. The collection of particles between 0.1-1mm is based on its physical characteristics. and specific uses. [0003] At present, the general air conveying device is only suitable for the conveying of solid granules or powders, and the variety of conveyed materials is single, the particle size range is narrow, and the versatility and flexibility are poor. [0004] Depend on figure 1 It can be seen that the granular material airflow conveying device is: the granular material ...
