Abstract

The invention provides a coarse powder separator which comprises an air discharging pipe (2) positioned on the top, an air feeding pipe (1) positioned at the bottom, a conical inner shell (3), a conical outer shell (4), a reflection cone (5) arranged between the conical inner shell (3) and the conical outer shell (4), a guide blade (6) arranged above the conical inner shell (3) and the conical outer shell (4), a coarse powder discharging pipe (7) arranged below the conical outer shell (4), and a fine powder discharging pipe (8) arranged below the conical inner shell (3). The coarse powder separator has the characteristics of economical and practical performance, simple and compact structure, easiness in mounting, convenience in maintenance and the like and can be used for separating powdered materials in grinding of cement industries.

Description

A kind of mill separator
Technical field
The present invention relates to a kind of mill separator, belong to the separation equipment technical field.
Background technology
Mill separator is that the defective meal in the coal dust that coal pulverizer is sent is separated from gas, powder mixture, sends the device that coal pulverizer continues to grind back to.
Existing mill separator, the structure more complicated, difficulty is installed, safeguard not quite convenient.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of mill separator is provided.
Mill separator of the present invention, comprise the discharge pipe (2) that is positioned at the top, be positioned at the bottom blast pipe (1), taper inner housing (3), conical shell body (4), be located at reflection cone (5) between taper inner housing (3) and the conical shell body (4), be located at taper inner housing (3) and conical shell body (4) top guide vane (6), be located at the meal discharge nozzle (7) below the conical shell body (4) and be located at fine powder discharge nozzle (8) below the taper inner housing (3).
Mill separator of the present invention has characteristics such as economical and practical, simple and compact for structure, that installation is easy, easy to maintenance, can be used for the separation of granular material in the cement industry grinding.
Description of drawings
Fig. 1 is the structural representation of mill separator of the present invention.
The specific embodiment
As shown in Figure 1, mill separator of the present invention, comprise the discharge pipe (2) that is positioned at the top, be positioned at the bottom blast pipe (1), taper inner housing (3), conical shell body (4), be located at reflection cone (5) between taper inner housing (3) and the conical shell body (4), be located at taper inner housing (3) and conical shell body (4) top guide vane (6), be located at the meal discharge nozzle (7) below the conical shell body (4) and be located at fine powder discharge nozzle (8) below the taper inner housing (3).
The workflow of mill separator of the present invention is as follows: meal enters space between taper inner housing (3) and the conical shell body (4) from blast pipe (1), the bulky grain meal is subjected to effect of inertia to collide reflection cone (5), fall conical shell body (4) bottom, slide along conical shell body (4) inwall, discharge from meal discharge nozzle (7).Air-flow enters in the taper inner housing (3) through guide vane (6) after rising to the top, rotate downwards, less coarse granule gets rid of under the effect of centrifugal inertial force to the inwall of taper inner housing (3), inwall along taper inner housing (3) falls, and also enters meal discharge nozzle (7) at last through fine powder discharge nozzle (8) and discharges.

Claims (1)

1. mill separator, it is characterized in that, comprise the discharge pipe (2) that is positioned at the top, be positioned at the bottom blast pipe (1), taper inner housing (3), conical shell body (4), be located at reflection cone (5) between taper inner housing (3) and the conical shell body (4), be located at taper inner housing (3) and conical shell body (4) top guide vane (6), be located at the meal discharge nozzle (7) below the conical shell body (4) and be located at fine powder discharge nozzle (8) below the taper inner housing (3).
