Abstract

The invention discloses a feeding system. The feeding system comprises a feeding device; the feeding device comprises a material cylinder; in the material cylinder, a plurality of separating plates are arranged along the vertical direction at intervals; an accommodation space is formed between each pair of adjacent separating plates; stirring assemblies are arranged in the accommodation spaces; each separating plate is provided with an opening; the bottom of the feeding device is provided with a powder blanking port; the feeding system also comprises a first sealing member which is arranged between the lowest separating plate and the stirring assembly in the lowest accommodation space, and a second sealing member which is arranged between the bottom plate of the material cylinder and the stirring assembly in the lowest accommodation space. The feeding system is capable of solving problems in the prior art that feeding stability is easily influenced by downstream gas pressure fluctuation, feeding metering precision is low, material running and material impacting are caused.

Description

technical field [0001] The invention relates to the technical field of powder transportation and feeding equipment, in particular to a feeding system suitable for small and medium-sized pulverized coal industrial boilers. Background technique [0002] Powder is commonly used in pulverized coal industrial boilers, kilns, cement, chemical, pharmaceutical and other industries. Small thermal power plants that use pulverized coal as fuel, cement batching production and other industries are inseparable from powder feeding technology. Powder feeding Technology is also a key technology for the above-mentioned industries. [0003] The core of existing powder feeding technology metering is volumetric metering. The key to volumetric metering is that a certain volume of powder must maintain a relatively constant powder concentration. During the feeding process, the powder within the volume of the metering unit The concentration is easily affected by other devices in the upstream and do...
