Abstract
The utility model discloses a double-layered isolating plate for a cement pulverizer, which comprises a grate plate and a blind plate, wherein, the cylindrical space between the grate plate and the blind plate is a sieving warehouse, a discharging cone is installed on an axial center part of the sieving warehouse, a sieve plate is arranged between the grate plate and the blind plate, a plurality of arc-shaped lifting plates in outward spoke-shaped extended arrangement along the discharging cone are arranged between the grate plate and the sieving plate, and the ar-shaped lifting plates are provided with a plurality of bar-shaped sieving holes extended in the radial direction. The utility model provides larger lifting space, the material can be lifted many times, and the arc-shaped lifting plates have the double effects of lift and sieving; the utility model has the advantages of high powder selecting efficiency, favorable lifting and winnowing effects, and product quality improvement, the production output per machine hour is improved by 15-20%, and the cement fineness is reduced from 5-6% of R0.08 to 3-4% of R0.08; a grid mesh added on the discharging cone completely solves the problem that steel balls and forgings are mixed in the warehouse, and the failure rate of the machine is reduced.
Description
Technical field
The utility model relates to a kind of double-layered isolating plate that is used for cement grinding mill.
Background technology
In the prior art, the double-deck partition device for barn of long cement mill, comprise grate plate, blind plate, lifting blade, discharging awl, as shown in Figure 2, its operation principle is that material enters by grate plate in the support ring of double-layered isolating plate, and the radially dividing plate of support ring is divided into the little compartment of several independent with space between grate plate and blind plate, though radially dividing plate has certain lifting effect, but its lifting is insufficient, a large amount of fine powders turn back to former storehouse, cause the grinding phenomenon, have increased production cost.
The utility model content
Problem to be solved in the utility model is to provide a kind of double-layered isolating plate that is used for cement grinding mill, and its lifting blade has the double effects of lifting and screening, lifting selection by winnowing and screening effect ideal.
The utility model adopts following technical scheme, comprise grate plate, blind plate, cylindrical space between described grate plate and the blind plate is the screening storehouse, screening storehouse axle center part is equipped with the discharging awl, be provided with sieve plate between described grate plate and the blind plate, be provided with the several piece curved throwing plate that outwards is spoke-like extension arrangement along the discharging awl between described grate plate and the sieve plate, described curved throwing plate is provided with several bar shaped screen holes that radially extend.Its operation principle is: grate plate is kept off large granular materials in the storehouse, upstream, less material by grate plate at first enters in the little screening storehouse that is separated out by curved throwing plate, bar shaped screen hole is communicated with each little screening storehouse, the grinding machine operation drives curved throwing plate rising lifting, material is repeatedly kicked up, and carries out selection by winnowing, and bar shaped screen hole is to material screening simultaneously, coarse fodder returns the storehouse, upstream by the discharging awl, and the fines that closes the symbol granularity requirements enters the storehouse, downstream by sieve plate, blind plate.
As improvement of the present utility model, described bar shaped screen hole is bored an end away from discharging on curved throwing plate bigger, a relative other end is less, different curved throwing plate bar shaped screen hole sizes are arranged on and are divided into two groups on the circumference, and the size setting of the bar shaped screen hole of two adjacent curved throwing plates increases progressively by the grinding machine direction of rotation in same group.This set can make material pass through repeatedly screening by scalping to dusting cover, has guaranteed screening effect.
, be provided with in the through hole between several little sieve compartments that described curved throwing plate is separated out and the discharging awl and prevent that steel ball from entering the aperture plate of little sieve compartment with novel further improvement as this product, avoided steel ball to break the situation of sieve plate.
Improve once more as of the present utility model, the small end of the taper hole of described discharging awl is provided with and prevents that ball from forging the aperture plate of scurrying the storehouse.
Employing the utlity model has following advantage:
1, because curved throwing plate is provided with radially the bar shaped screen hole that extends, and each little screening storehouse is interconnected by bar shaped screen hole, and its lifting space is bigger, and material can repeatedly be kicked up, and the lifting selection by winnowing is satisfactory for result.
2, curved throwing plate has the double effects of lifting and screening.After material entered the screening storehouse, the double-layered isolating plate of more former employing support ring structure had increased the repeatedly lifting screening operation in each little screening storehouse, its screening effect ideal.
3, its grinding efficiency height has improved production efficiency greatly, has reduced production cost.Not only unit-hour output can improve 15-20%, has also improved product quality, and cement fineness is reduced to the 3-4% of R0.08 by the 5-6% of R0.08.
4, discharging awl is gone up the aperture plate that increases, and has thoroughly solved the problem that the storehouse is scurried in the steel ball forging, has reduced machine-spoiled rate.

The specific embodiment
As Fig. 1, Fig. 3 and shown in Figure 4, a kind of embodiment of the utility model comprises grate plate 1, blind plate 2, cylindrical space between described grate plate 1 and the blind plate 2 is the screening storehouse, screening storehouse axle center part is equipped with discharging awl 4, also there is not sieve plate 5 between described grate plate 1 and the blind plate 2, be provided with the several piece curved throwing plate 6 that outwards is spoke-like extension arrangement along discharging awl 4 between described grate plate 1 and the sieve plate 5, described curved throwing plate 6 is provided with several bar shaped screen holes 7 that radially extend.
As shown in Figure 4, as improvement of the present utility model, it is bigger that the utility model comprises that described bar shaped screen hole 7 is bored 4 one ends away from discharging on curved throwing plate 6, a relative other end is less, different curved throwing plate 6 bar shaped screen holes 7 sizes are arranged on and are divided into two groups on the circumference, and the size setting of the bar shaped screen hole 7 of two adjacent curved throwing plates 6 increases progressively by the grinding machine direction of rotation in same group.
As shown in Figure 3, further improve as the utility model, the utility model comprises being provided with in the through hole between several little sieve compartments that described curved throwing plate is separated out and the discharging awl 4 and prevents that steel ball from entering the aperture plate of little sieve compartment.
Improvement again is that the small end of the taper hole of described discharging awl 4 is provided with and prevents that ball from forging the aperture plate of scurrying the storehouse.
The utility model is not limited to the concrete structure of the foregoing description, and the equivalent transformation of other homogeneous structure all falls within the protection domain of the present utility model.
