Abstract

The invention relates to a rotor disc (23) which is a material crushing device inside a grinder and belongs to the field of crushers. A central material feeding way is formed by feeding materials through a feeding hole (33) of a static-knife reverse air cavity, a blade surface share angle is formed by four dynamic knifes (2) positioned in the center of the rotor disc and three static knifes (4) positioned on a reverse air cavity (13) and strongly shears and cuts the materials from outside to inside after the centrifugal absorption of the rotor disc, and four knife groups (25) crush the materials when operate at a high speed. The rotor disc has more superior effect when being used for dry powder, wet powder and water powder; only fed to the inlet of a reversing cavity, the material is automatically absorbed; the rotor disc is safe, saves energy and has high efficiency and multiple functions.

Description

Rotor disk

The present invention: the rotor disk in the outer power pulverizer, belong to the pulverizer field, be used for material and pulverize industry.

And the rotor disk in the existing pulverizer has many disks interlock hammer slice type, the cell tray post side feeding that is such as tooth-like, the object of the present invention is to provide the centrifugal suction ecto-entad of a kind of center feeding ring to shear the combination break bar and sieve crushing technology entirely, go comparison mutually, obviously be better than the operating efficiency of the rotor disk in the above-mentioned existing pulverizer.

The present invention has changeed dish (23) purpose and can realize by following measure:

Link on round steel dish (17) (22) four moving knife bedplates (20) by (19) four moving knife bedplates of four gussets (20) and respectively to adorn a moving knife (2), the peripheral spacing equalization of (17) and (22) four knife wheel set (25) are housed.

1. and 2. Figure 10, photo in kind.Two in attached photo.

Now in conjunction with the accompanying drawings: rotor disk (23) is described in detail explanation.

See Fig. 5, the plectane at the bottom of the rotor disk of left side (17), the side projection (18) that the axis hole (24) that protrude the center is seen (17), the round steel circle (22) (side projection figure sees (21)) of figure right side rotor disk.On (17), (22), make two orthogonal diameters (28) respectively and hand over four gong holes (26) of outer inner round side, two orthogonal diameters (29) (angle of (29) and adjacent (28) be 45 spend).The middle part is four fan-shaped gussets (19).

See Fig. 3, referring to Figure 10 1., four (19) each end is cut friendship with (24), each holds the orientation of the point (30) of handing over (22) and (17) to be fixed on the bottom surface of (24), (17) and (22) in addition, (referring to Fig. 9), (20) with the inner round wall of arc limit and (22) coincide affixed, a straight flange is affixed with (19), four (2) that have a two-sided edge of a knife are respectively by together firm with the gong bolt from gong mouth (1) on the body and gong mouth (1) on (20).(referring to Fig. 8, Fig. 4) four knife wheel set (25) on the rotor disk (23), each (25) are gone up string by wheel cutter shaft (12) and are adorned the flywheel knife (8) that the centre of three or seven circles has circular hole, per two (8) are a gap stay tube (5) (the side projection figure of (5) sees (6)) at interval, (12) pack in the axis hole of each end of two braces (10) in two ends, lock by lock pin (11), (17) on two axis holes of the in addition end of two (10) and (23), (22) every relative two (26) alignment on, be coupling respectively with connecting axle (9) and (illustrate: four (25) are housed on (23) altogether, also can be equipped with five, six, seven, eight (25)), it is individual that (referring to Fig. 2) (24) by (23) are fixed in main shaft (37).

The sample photo of seeing Fig. 7, Figure 10 2. (the tubbiness wall (31) of inverted ventilation chamber (13) (referring to the side projection diagram (14) of (13)) go up with the gong bolt fastening (4) of three spacing equalizations (see Fig. 9, have two stationary knifes (3) that connect the hole, turn up with an angle of 90 degrees by the broken line on its face (31), see the lateral plan stationary knife (4) of the stationary knife of turning up (3).), portion of bottom center is provided with charging circular hole (33), and top (34) of disc type are all apart from being provided with nine gong holes (35).

See Fig. 6, referring to the sample photo 1., the interface (37) of (15) goes up all apart from being provided with six gong holes (36), the outer inner round side of (16) is all apart from being provided with six gong holes (36), outside interior the justifying all apart from being provided with nine gong holes (35).

(13) with the assembling (referring to Fig. 2) of (15).

(16) aliging with (36) of (15) in (36), aligns with (35) of (16) in (35) on (34) of (13), use respectively on (13) after the fastening assembling of gong bolt three (4) respectively with (23) on the tip clearance of four (2) coincide.

(23) in the operation principle of pulverizer.

Because charging aperture (33) charging by quiet cutter inverted ventilation chamber, and form a kind of center feeding manner, the centrifugal suction of rotor disk, the running of rotor disk moving knife forms sword face shear angle with inverted ventilation chamber stationary knife, the ecto-entad ring is sheared material, the wind-force that the built-in gusset of Sui is produced is carried out material in sieve sheet place, and by four groups of interlock knife wheel set (25) of centrifugal rotor dish, flywheel knife generation impulsive force is pulverized material in running up.

The advantage explanation:

This installs rotor disk (23), substitutes the rotor disk of prior art in the pulverizer, with centrifugal Power sucks material, and can what suck, and how much outer the discharge body is after pulverizing, and can freely keep Charging with pulverize to discharge the outer balance of body, make between pulverizer kinetic energy and the material self-assembling formation the highest Output is used thin flywheel knife in that flywheel knife is technical, more effective the material fiber is shredded. Many wheels, 360 degree wheel blade faces increase the service life, and are more superior at dry powder wet-milling pigment, in safety The aspect as long as being sent in porch, inverted ventilation chamber by the material of powder, namely sucked voluntarily, is avoided using Hand and the attached thing that helps are sent to, and be safe and efficient energy-conservation, and a tractor serves several purposes is widely used in the comminuting matter field.
