Abstract
The utility model relates to an improved coal powder separator structure for a coal mill. The utility model provides a coal powder separator which has greater centrifugal force and can separate more fine particles, comprising a center coal cake falling duct, an external conical shell outside of the center coal cake falling duct, an internal conical shell, a coal powder distribution box provided with a coal powder outlet and a diverting door which are arranged respectively over the internal conical shell. The utility model is characterized in that a casing is arranged outside of the bearing of the center coal cake falling duct; a flakey blade is arranged at the bottom of the casing inside the internal conical shell; a belt pulley is arranged at the upper end of the casing.
Description
Technical field:
The utility model relates to the improvement of the coal dust classifier structure of coal pulverizer.
Background technology:
The major function of the coal dust classifier of coal pulverizer is exactly to separate thinner coal dust from coal dust.This primary structure is: be the center with the coal spout, be provided with male-tapered housing, inner conical housing outward, the top of inner conical housing is respectively arranged with coal dust distributor box with discharge, is folded to door.During use, the wind coal dust is between male-tapered housing, the inner conical housing, again through be folded to door, behind the inner chamber rotating centrifugal of inner conical housing, the discharge on the coal dust distributor box is discharged; Bigger particle then falls within the bottom of inner conical housing in the coal dust, discharges then to get final product.But this equipment centrifugal force that to have major defect be coal dust produces around the rotation of inner conical inner walls is little at present, so the coal dust separating particles is thinless, and uniformity is also poor.
The utility model content:
The utility model is exactly at the problems referred to above, and the coal dust classifier that a kind of centrifugal force is big, separating particles is thinner is provided.
The utility model adopts following technical scheme: the utility model comprises the center coal spout, the center coal spout is outward male-tapered housing, inner conical housing, the top of inner conical housing is respectively arranged with coal dust distributor box with discharge, is folded to door, the bearing of its structural feature center coal spout is outside equipped with sleeve pipe, the bottom of the sleeve pipe in the inner conical housing is provided with the sheet blade, and the sleeve pipe upper end is provided with belt pulley.
The beneficial effects of the utility model:
Because the bearing of the utility model center coal spout is outside equipped with sleeve pipe, the bottom of the sleeve pipe in the inner conical housing is provided with the sheet blade, and the sleeve pipe upper end is provided with belt pulley; After the sheet blade that rotates just is thrown to particle bigger in the coal dust on the inner conical housing wall, drop down onto the bottom of inner conical housing, fail away getting final product then; Thinner coal dust then passes gap, the discharge of the coal outlet on pulverized coal distributor again between the sheet blade; The coal dust of discharging is not only thinner, good uniformity.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model comprises center coal spout 1, outside the center coal spout 1 is male-tapered housing 2, inner conical housing 3, the top of inner conical housing 3 is respectively arranged with coal dust distributor box 13 with discharge 12, is folded to door 7, the bearing 10 of center coal spout 1 is outside equipped with sleeve pipe 6, the bottom of the sleeve pipe 6 in inner conical housing 3 is provided with sheet blade 5, and sleeve pipe 6 upper ends are provided with belt pulley 14.
For preventing that dust from entering bearing 10, guarantee that bearing 10 runs well, and can be provided with sealing gasket 9 in the both sides of bearing 10.
Claims (3)
