The specific embodiment:
Structural principle of the present utility model and technological process are as follows, and the utility model super-fine crusher includes feeder, crushing mechanism, screening mechanism, gear, and four mechanisms illustrate respectively:
One, feeder:
The part of feeder is seen Fig. 3, is the top of whole disintegrating machine, comprise hopper 53 and be communicated with it about two feed parts 52, the through hole that feed part 52 cooperates with main shaft 15 is so that whole feeder is installed on the main shaft 15.During work, need broken material to send into earlier in the hopper 53, two sides, the left and right sides enters into lower part feed part 52 respectively simultaneously subsequently, and feed part 52 inside have screwfeed mechanism, make material uniformly, advance in the crusher chamber, carry out fragmentation according to design charging quantity.
Two, crushing mechanism mainly comprises crusher chamber, rotor portion and several major parts of counterattack plate body, sees Fig. 1, and rotor portion is installed on the main shaft 15, and the counterattack plate body surrounds rotor portion, and the outer cavity of counterpunch board internal rotor part is a crusher chamber.Wherein:
(1) rotor portion: rotor portion comprises at least two inner flanges 24, at least two outward flanges 20, at least one little axle 51, a slice hammer leaf 21 at least.Wherein inner flange 24 cooperates by key with main shaft 15 or other mechanical system is fixed together and rotate synchronously, outward flange 20 is fixed on the periphery of inner flange 24 by screw or alternate manner, at least one circular arc cutaway is respectively arranged on the interior outward flange, after interior outward flange is connected, form for little axle 51 circular holes that pass through; Hammer leaf 21 is on the little axle 51 between the adjacent flange in the left and right sides on the main shaft.Certainly, above-mentioned in the structure of outward flange be that dismounting is for convenience considered to constitute and divided body structure, also can wholely form, preferred 4 of the quantity of little axle preferably differs from 90 degree each other and arranges.
(2) counterattack plate body: see Fig. 5, form, form a profile and be roughly columniform hollow-core construction by multi-disc counterpunch board 49 and counterpunch board side plate 59.Its structure is seen Fig. 5, multi-disc counterpunch board 49 left and right sides are fixed on the side plate 59, counterpunch board 49 prolongs the spindle axis line and tilts to arrange at a certain angle, section of whole formation is roughly the mechanism structure (seeing Fig. 5 b) of annular, have the slit to pass through for partial material between the adjacent counterpunch board 49, the gap in slit can be selected according to the different of material with the angle of counterpunch board.The material of counterpunch board was for just now, preferred 65Mn steel, preferred 32 of the quantity of counterpunch board.The angle of inclination can be adjusted as required, preferred 62 degree.
In the course of work: the rotor portion high speed rotating, counterattack plate body (49) is with relative low-speed running with the rotor rightabout, material enters in the crusher chamber, be subjected to hammer leaf 21 percussions on the high speed rotor rotated and fragmentation, and material obtains kinetic energy from hammer leaf 21, at a high speed rush at counterpunch board 49, be subjected to once more broken, counterpunch board and the rotation of rotor rightabout, because the counterpunch board body structure adopts said structure, only bloat outside the crusher chamber under the air-flow effect less than the generation in the running up of hammer leaf and rotor of the small material in described slit.
Three, screening mechanism: comprise screen cloth 54, it is enclosed in outside the counterattack plate body, sees Fig. 4.Bloated small particle outside the crusher chamber through hitting plate body, rushed at tubular screen cloth 54, separated by screen cloth, passing screen cloth 54 less than the material of sieve screen apertures falls in the charging conduit 50 subsequently, and be discharged from outside the body, entered again in the crusher chamber greater than the material of sieve screen apertures slit by the counterattack plate body, broken once more.
Four, gear: see Fig. 6, main shaft 15 drives rotor and runs up clockwise, and an end of main shaft is adorned a small diameter pulleys 34, small belt pulley passes to variable-speed shaft 58 1 ends by belt, big belt pulley 57 being housed, and having certain rotating ratio between small belt pulley and the big belt pulley, for example is 3:1; The other end of variable-speed shaft is equipped with pinion 56, strikes back the gear ring 25 teeth engagement that plate body, screen cloth are connected in pinion and the machine, it has a stable drive ratio, for example be 10:1,, and do the rightabout motion so the rotating speed speed ratio of main shaft 15 and relative low speed counterattack plate body is 3:1 * 10:1=30:1.Certainly, also can use two power sources to drive main shaft 15 respectively rotates with opposite direction with the counterattack plate body.In addition, above-mentioned gear ratio can be selected as required, and above-mentioned drive disk assembly also can be replaced with other drive disk assembly commonly used of this area, as sprocket wheel, turbine etc.
During assembling, screening mechanism and counterattack plate body dress are installed in the cylinder, and as illustrated in fig. 1 and 2, integral installation is on main shaft then; Feeder among Fig. 4 is installed on the main shaft, and the discharging opening of feed part 52 is corresponding to the feeding mouth of Fig. 2 cylinder both sides.
The concrete course of work of the present utility model is as follows: material is put into hopper 53, enter the inlet of cylinder from outlet through the screwfeed mechanism in the feed part 52, and fall in the crusher chamber, material is broken under the effect of the hammer leaf 21 that main shaft 15 drives subsequently, and acquisition kinetic energy rushes at the counterattack plate body, the counterattack plate body rotates with opposite direction with main shaft 15, rush at the material size of counterattack plate body big to return crusher chamber broken once more, what size was little passes the slit between the counterpunch board 49 and rushes at screen cloth 54, wherein passing screen cloth less than the material of sieve screen apertures falls in the charging conduit 50, discharge subsequently outside the main body, return in the crusher chamber broken once more by the slit between the counterpunch board 49 once more greater than the material of sieve screen apertures.Such structure makes big material through second-time breakage, can reach 2mm, 1.5mm, the following raw meal particle size of 1mm, material is in the filtration by the plate body of process counterattack earlier before the screen cloth 54 in addition, make that screen cloth is not easy to be damaged, this point is exactly the characteristics of the utility model super-fine crusher special construction, in addition according to the difference of material with need the different of granularity, can select the slit and the corresponding screen cloth 54 of installing plate 49.
