Vertical mill powder concentrator labyrinth sealing structure

The invention relates to a vertical mill powder concentrator labyrinth sealing structure. The vertical mill powder concentrator labyrinth sealing structure comprises a powder concentrator shell and acage wheel arranged in the powder concentrator shell; a loop of a sealing wide plate is arranged at the position of a rotary part on the cage wheel; a fastening bolt is arranged at the corresponding position of the powder concentrator shell; and a pressing plate is arranged on the fastening bolt. In the vertical mill powder concentrator labyrinth sealing structure, a sealing plate made of a composite rubber material is arranged through the pressing plate and the fastening bolt, the sealing plate is soft in texture, and the sealing plate can effectively form a soft connection sealing form withthe sealing wide plate arranged on the cage wheel, so that the sealing effect is achieved; furthermore, even if the conditions of axial jumpiness, eccentricity and the like exist, the steel plate andthe sealing plate on the ca
