Description
Affiliated technical field
The utility model relates to a kind of inner choosing powder compartment device of cement grinding mill, especially a kind of combined spiral inner choosing powder compartment device.
Background technology
At present, employed equipment is cement grinding mill in the grinding process of manufacture of cement, and spiral inner choosing powder compartment device generally is housed in the cement grinding mill.This device comprises grate plate, fine powder burden-guiding cone, meal burden-guiding cone, centring ring, porous plate, ventilation grate plate and spiral sieve plate assembly.Grate plate is arranged on centring ring medial surface one end, and spiral sieve plate assembly is arranged between big end of fine powder burden-guiding cone lateral surface and the centring ring medial surface.Spiral sieve plate assembly is made up of spiral sieve plate, front apron and backboard, and front apron and backboard are separately positioned on the frontal arc limit of spiral sieve plate and the below on backarc limit, and the ventilation grate plate is arranged on the other end of centring ring medial surface.During cement grinding mill work, spiral sieve plate is along with the rotation of cement grinding mill cylindrical shell, after powder taken up certain altitude, under the effect of powder self gravitation, from spiral sieve plate, slide to the meal burden-guiding cone from top to bottom, meal on the sieve plate imports cracking cabin by this burden-guiding cone and carries out fragmentation, and the fine powder that falls from the sieve aperture of sieve plate is ground by fine powder burden-guiding cone importing grinding storehouse.Because spiral sieve plate takes up powder in the process of certain altitude, near the sieve plate front edge powder is more, often a part of powder just directly rolls into cracking cabin from sieve plate without sorting for being positioned at of being taken up, this had both made cement grinding mill have the grinding phenomenon, influenced the interior grinding efficiency of cement grinding mill simultaneously again.
The utility model content
The utility model provides a kind of combined spiral inner choosing powder compartment device.This device not only improves the interior grinding efficiency of cement grinding mill, and reduces the generation of crossing the grinding phenomenon in the mill.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises spiral sieve plate assembly, spiral sieve plate assembly is made up of spiral sieve plate, front apron and backboard, front apron and backboard are separately positioned on the frontal arc limit of spiral sieve plate and the below on backarc limit, spiral sieve plate assembly also comprises powder blocking plate, powder blocking plate is arranged on the medium position of spiral sieve plate, and the bottom of powder blocking plate is provided with powder-guiding hole.
The bottom of described retaining powder retaining is provided with 3 to 5 powder-guiding holes.
Owing to powder blocking plate is set at the middle part of spiral sieve plate, when of the rotation of spiral sieve plate along with grinding machine, material is taken up behind the certain altitude, under the effect of self gravitation, slide to from top to bottom the process of meal burden-guiding cone from this sieve plate, being positioned near the powder of sieve plate front edge is stopped by striker plate, make a part of powder force to screen by the compass screen surface of striker plate front side, another part powder screens through the compass screen surface that the powder-guiding hole of striker plate enters the striker plate rear side, therefore be positioned near the shunting with powder-guiding hole of stopping of powder more the sieve plate front edge by striker plate, they are effectively screened, just directly do not roll into phenomenon in the cracking cabin without screening from sieve plate thereby powder can not take place.Because powder is effectively screened, so the interior grinding efficiency height of cement grinding mill, also reduce the generation of crossing the grinding phenomenon in the mill simultaneously.

The specific embodiment
Among Fig. 1 and Fig. 2, grate plate 2 is arranged on an end of the medial surface of centring ring 1, meal burden-guiding cone 8 links with the big end of fine powder burden-guiding cone 7, the small end of meal burden-guiding cone 8 is arranged in the grate plate centre bore 14, form between the outer surface of grate plate centre bore 14 and meal burden-guiding cone 8 and lead the powder passage, be laid with several spiral sieve plate assemblies between big end of fine powder burden-guiding cone 7 lateral surfaces and centring ring 1 medial surface, at Fig. 3, among Fig. 4 and Fig. 5, spiral sieve plate assembly is by spiral sieve plate 3, front apron 9 and backboard 4 are formed, and front apron 9 and backboard 4 are separately positioned on the frontal arc limit 10 of spiral sieve plate 3 and the below on backarc limit 11.The below of front apron 9 and backboard 4 is provided with porous plate 5, and ventilation grate plate 6 is arranged on an inboard other end of centring ring 1, leaves the space between ventilation grate plate 6 and the porous plate 5, as Fig. 1, Fig. 3 and shown in Figure 4.Form between porous plate centre bore 13 and ventilation grate plate centre bore 12 and fine powder burden-guiding cone 7 lateral surfaces and lead the powder passage.The efficiency of separation and the effectively interior generation of crossing the grinding phenomenon of minimizing mill in order to improve cement grinding mill are provided with powder blocking plate 15 at the middle part of spiral sieve plate, and the bottom of powder blocking plate 15 is provided with 3-5 powder-guiding hole 16, as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 5.In cement grinding mill when work,, material is at first under the steel ball percussion in the ball storehouse, is fractured into the particle size tiny powder that differs, and enters the space that forms by between some spiral sieve plates 3 and the grate plate 2 by grate plate 2 then.Along with the rotation of grinding machine, powder by the inclined screen of spiral sieve plate 3 wear play certain altitude after, under the self gravitation effect, from the compass screen surface that this sieve plate 3 tilts, slide to meal burden-guiding cone 8 from top to bottom, powder carries out sorting at compass screen surface this process.Being positioned near the powder of these sieve plate 3 front edges is stopped by striker plate 15, make that a part of powder forces that compass screen surface by striker plate 15 front sides screens, another part powder screens through the compass screen surface that the powder-guiding hole 16 of striker plate 15 enters the striker plate rear side, meal on the compass screen surface is imported cracking cabin by meal burden-guiding cone 8 and carries out fragmentation, the fine powder that from the sieve aperture of compass screen surface, falls, after entering several spaces that constitute by centring ring 1, fine powder burden-guiding cone 7, spiral sieve plate 3, front apron 9, backboard 4 and porous plate 5, import to the grinding storehouse by fine powder burden-guiding cone 7 and grind.Owing to be positioned near powder more spiral sieve plate 3 front edges by the stopping and the shunting of powder-guiding hole 16 of striker plate 15, they effectively screened.Thereby powder can not take place just directly roll into phenomenon in the cracking cabin from spiral sieve plate 3 without screening.Because powder is effectively screened, so the interior grinding efficiency height of cement grinding mill, also reduce the generation of crossing the grinding phenomenon in the mill simultaneously.
