Problems solved by technology

[0003] In the powder selection process of the existing centrifugal powder separator, the fine powder is easy to be entrained with the bulk materials and falls, and the fine powder selection rate is low; at the same time, after the motor is turned off, the airflow of the cyclone is easy to flow back due to the air pressure difference into the air distribution cylinder, and then a certain amount of fine powder entrained is returned to the air distribution cylinder, and finally falls together with the bulk material, resulting in a further reduction in the selection rate, which needs further improvement

Abstract

The invention relates to a novel powder concentrator comprising a cutting cylinder, a cutting blade, a powder concentrating cylinder, an air distributing cylinder, a drive assembly, a main shaft, a wind wheel, a top plate, a bearing seat, a cyclone cylinder, an air inlet chamber, first flap valves, a second flap valve, main air pipes, a mixed material cylinder, a guiding assembly, a conical feeding hopper, a feeding channel and air suction pipes. According to the novel powder concentrator, an air guide assembly can effectively extract fine powder mixed with bulky materials and pick out the fine powder through air flow, so that the fine powder concentrating ratio is improved; and meanwhile, by means of a movable sealing assembly, the fine powder concentration ratio is further improved.

Description

technical field [0001] The invention relates to a novel powder separator. Background technique [0002] At present, the powder separator is widely used in the coal mill, the raw material unloading drying mill and the cement mill system in the new dry process cement production line. There are many types of powder separators, and different types are suitable for different materials, which are generally common. The advanced powder separators include cyclone type cyclone powder separator, three-separation powder separator, centrifugal powder separator, special separator for coal mill, special separator for calcium powder, etc. [0003] During the powder selection process of the existing centrifugal powder separator, the fine powder is easy to be entrained with the bulk materials and falls, and the fine powder selection rate is low; at the same time, after the motor is turned off, the airflow of the cyclone is easy to flow back due to the pressure difference into the air distrib...
