Abstract
The invention discloses a sealing structure of a pulverizer fan. The sealing structure of the pulverizer fan comprises a fan shell body and a main shaft. A sleeve is arranged on the inner side of the pulverizer fan shell body. The main shaft penetrates through the sleeve and is connected with a fan blade disk. Threads are arranged on the surface of the main shaft combined with the sleeve. The sealing structure of the pulverizer fan has the remarkable advantages of not leaking powder materials.
Description
Technical field:
The present invention relates to the sealing configuration of a kind of disintegrating apparatus, particularly a kind of wind machine of disintegating mill.
Background technique:
At some shredder, the junction of blower fan and main shaft exists due to inevitable gap, just have a certain amount of powder from then on gap location leak away.
Summary of the invention:
The present invention seeks to propose a kind of sealing configuration that does not leak a kind of wind machine of disintegating mill of powder.
The technological scheme that realizes the object of the invention is, a kind of sealing configuration of wind machine of disintegating mill, comprise Blower Housing and main shaft, it is characterized in that: in described Blower Housing inboard, be provided with sleeve, described main shaft is through at this sleeve and is connected with fan blade disc, on the main shaft surface combined with described sleeve, is provided with screw thread.
The present invention has the remarkable advantage that does not leak powder compared with the prior art.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
Leak a minute terrible problem in order to solve existing blower fan and main shaft junction, the present invention adopts following technical proposals, in Blower Housing 1 and the junction of main shaft 2, a sleeve 3 is set, on the side face at main shaft and the place of combining of sleeve, screw thread 4 is set, the direction of this screw thread should be pointed to Blower Housing inside when main shaft rotates.The main shaft of this worm structure, when main shaft rotates, screw thread can be pushed in Blower Housing and can not leak leaking powder between main shaft and sleeve.
