The accompanying drawing explanation

Fig. 1 is the structural representation of the guide type tup used of a kind of micronizer of the utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the perspective view of the guide type tup used of a kind of micronizer of the utility model.

The specific embodiment

With reference to Fig. 1, be described as follows: the guide type tup that a kind of micronizer is used, comprise and be shaped as the parallel hexahedral tup body in two sides, in parallel two sides, one side is crushed face 1, for the gear ring with pulverizer, clashes into the friction comminuting matter; Another side is parallel bottom surface 6.At the crushed face 1 with the tup body, on adjacent nearly gear ring face 5, arrange and the similar regularly arranged projection of the gear teeth 4 of gear.Tup is done rotatablely move relative with gear ring under driven by motor, crushed face 1 and the gear teeth 4 all can with the mutual shearing friction comminuting matter of gear ring.In addition, the material that the gear teeth that arrange on nearly gear ring face can drive after pulverizing continues to rotate around the spindle motion, prevents the disk of crushed material wearing and tearing for fixed hammer.

Further, the crushed face 1 directly clashed into material on described tup body is plane, and the intersection of described crushed face 1 and nearly gear ring face 5 and the tooth top of the gear teeth 4 are coplanar, and described coplanar vertical with crushed face 1.That is to say that the gear teeth 4 are concordant with crushed face 1, tup and gear ring are sheared mutually like this, and when mutually clashing into friction, the gear teeth 4 are identical with crushed face 1 with the distance of gear ring with the distance of gear ring, more even to the pulverizing of material like this.Crushed face 1 is plane, is not curved surface, and crushed face 1 is larger with the shearing force that gear ring clashes into like this, makes material be pulverized more thoroughly.

Further, on the flank of tooth of the described gear teeth 4 and material impacting, wearing layer 2 is set.Each gear teeth 4 has two flank of tooth, when tup rotates under main shaft drives, each gear teeth is relative with gear ring while rotating, it is directly to clash into material that a flank of tooth is arranged, so in order to increase the wearability of tup, on this flank of tooth surface, wearing layer 2 is set, wearing layer 2 materials are carbide alloy, as materials such as tungsten carbides.

Further preferred, the profile of tooth of the described gear teeth 4 is triangle.The flank of tooth that is the gear teeth 4 is plane, is not curved surface, and the shearing force formed between the gear teeth 4 and gear ring like this is larger, makes material be pulverized more thoroughly.And the flank of tooth of the gear teeth 4 is that plane can be so that the process of tup be simpler.

Further preferred, the Plane intersects at the teeth groove direction of the described gear teeth 4 and crushed face 1 place.The plane that is the teeth groove direction of the described gear teeth 4 and crushed face 1 place is not parallel, the angle of its formation is greater than 0 ° and is less than 90 °, like this, the gear teeth 4 are except can mutually shearing therebetween crushing material with gear ring, material after pulverizing can also be led, to the scope of pulverizing, can avoid like this material to overstay and make material excessively be pulverized in pulverizing place its water conservancy diversion, and new material really advance less than crushed zone.

Further, two installing holes 3 are set on described tup body, the hole line of centres of described two installing holes 3 is vertical with crushed face 1, and the hole direction of each installing hole 3 is parallel with crushed face 1.In actual use, tup is to be installed on a disk by driven by motor rotation, thereby rotation by disk makes tup and gear ring that the relative comminuting matter that rotates occur.Two installing holes 3 that the hole line of centres is vertical with crushed face 1 are set on the tup body, can so that tup after installation, its crushed face 1 line tangent with disk with place, its place is vertical, thereby guarantee that the shearing force produced between crushed face 1 and gear ring is larger, make material be pulverized more thoroughly.

Further, the area of the parallel bottom surface 6 relative and parallel with described crushed face 1 is less than the area of crushed face 1.Be that tup is one large one small shape, a side of directly clashing into material is large, is not reducing under the impact strength condition of tup like this manufacturing cost that can save tup.

Further, on described crushed face 1, wearing layer 2 is set.Thereby crushed face 1 clashes into the friction comminuting matter mutually with material, in long-term shock friction process, be easy to be worn, therefore is set the service life that the wearing layer 2 of one deck carbide alloy class can increase tup greatly on crushed face 1.

Further, face and crushed face 1 intersection distant with gear ring arrange wearing layer 2, and wearing layer 2 thickness on the Thickness Ratio crushed face 1 of wearing layer herein 2 are large.The wearing layer 2 that the face relative with nearly gear ring face 5 and the crossing place of crushed face 1 arrange the carbide alloy class on tup.By lot of experiments, prove, the most serious place of tup wearing and tearing is the side away from gear ring in fact, and this is because material is larger to the wearing and tearing of tup, therefore wearing layer 2 is set herein, can greatly increase the service life of tup, increases the replacement cycle of tup.

Further, described wearing layer 2 is carbide alloy, and described wearing layer 2 is welding with the tup body.Carbide alloy i.e. a kind of alloy material for being made by powder metallurgical technique by hard compounds and the binding metal of refractory metal: as W-Co kind carbide alloy, kennametal, tungsten titanium tantalum series hard alloy, tungsten titanium niobium series hard alloy.The connected mode of employing welding can be so that wearing layer 2 difficult drop-offs.And particularly preferably be Welding, utilize the fusing point ratio by the low-melting filling metal solder of brazing material, at lower than mother metal fusing point, temperature higher than the solder fusing point, utilize liquid solder at the mother metal moistened surface, sprawl and joint filling in the mother metal gap, mutually dissolve and diffusion with mother metal, and realize the welding method of the connection between part.Make temper at postwelding, like this, whole face of weld is smooth, welds more firm.
