Description

Technical Field

[0001] The utility model relates to the field of powder selection devices, in particular to a dust-proof structure for a powder separator. Background Technique

[0002] The powder separator is an indispensable key device in the industrial field, especially playing a crucial role in industries such as mines, metallurgy, building materials, and chemicals. With its advanced sorting principle and structural design, through the ingenious action of centrifugal force and air resistance, it can efficiently and accurately sort and classify granular materials, ensuring product quality and improving production efficiency. Whether in cement production, power supply, or metallurgical and chemical industries, the powder separator provides strong technical support for the development of modern industry with its excellent performance and wide application range.

[0003] The Chinese patent with the publication number CN204583500U discloses a powder separator, including a driving device, a main shaft, a bent pipe, a feeding port, a bracket, a primary air inlet, a secondary air inlet, and a fine powder air outlet. It is characterized by further including a drip ash hopper and a tail mill dust collector; the drip ash hopper is located below the fine powder air outlet and includes two tertiary air inlets and two ash cleaning doors. The outer diameter of the drip ash hopper gradually increases from the inner tangent of the tertiary air inlet to the ash cleaning door and then to the outer tangent of the air outlet. By improving the drip ash hopper of the powder separator and changing its outer diameter size, a good classification effect is achieved in the process of re-dispersing the coarser materials that are not dispersed in the drip ash hopper; in addition, a tail mill dust collector is added to collect the fine powder that cannot be collected by the powder separator housing, improving the classification effect and classification efficiency of the powder separator for particles; and improving the collection efficiency of fine powder.
