Abstract
The utility model two-edge hammer for pulverizers, which mainly solves the problem that the present cutting edges of rectangular hammers have inconspicuous effect. The long edges of rectangular hammers of the utility model is processed with triangle grooves, and the cross-section of the triangle groove is in parallel with the end of the short side of the rectangular hammer. The utility model fully maintains and exerts the function of a cutting edge whose both sides are provided with hard layers, and the efficiency of hammer type pulverizing is remarkably enhanced.
Description
The utility model is a kind of two-edged type hammer mills.
The hammer leaf of the beater disintegrating machine that uses mostly is rectangular configuration at present, relies on the bump of the hammer leaf corner of high speed circular motion to come comminuting matter during work.In comminuting matter, hammer leaf itself has also suffered wearing and tearing seriously, and especially the corner wearing and tearing are violent.The hammer leaf of 65Mn that often uses and tungsten carbide material manufacturing forms round sharp knife sword through its corner, wearing and tearing back at present, that is to say and have only a blade to come comminuting matter, through the heat treated hammer leaf made from low-carbon steel material in surface, its performance characteristics is that extexine is hard, middle soft, after limit end appearance hard formation need being worn away during work, competence exertion goes out the effect of two hard-edge layers, so the blade effect of two hard-edge layers embodiment is also not obvious.
The purpose of this utility model provides a kind of improved hammer mills, makes the blade effect of hammer leaf two hard-edge layers remarkable, thereby improves the crush efficiency of beater disintegrating machine.
The technical solution of the utility model: the long limit along the rectangle hammer leaf is processed with triangular slot, triangular slot cross section and rectangle hammer leaf minor face end parts parallel.
Advantage of the present utility model:, make that the blade effect on the long limit of hammer leaf is obvious, thereby improve crush efficiency owing to be processed with triangular slot along the long limit of hammer leaf.
Narrate embodiment of the present utility model in conjunction with the accompanying drawings.
Fig. 1 front view of the present utility model.
Fig. 2 left view of the present utility model.
The partial enlarged drawing of Fig. 3 the utility model left view.
The do not wear and tear A-A schematic diagram of starting section of Fig. 4 the utility model.
The A-A schematic diagram in cross section, Fig. 5 the utility model wearing and tearing back.
0.5~1.0mm can respectively be left to the undressed amount l of rectangle hammer leaf in the two ends of triangular slot cross section during enforcement, and the angle of triangular slot is 70 °~110 °, and the thickness of hammer leaf is 3~7mm.Long limit along the rectangle hammer leaf is processed with triangular slot as shown in the figure, makes the rectangle hammer leaf just not form two blades natively by machining before the wearing and tearing, handles the hardness that makes two blade districts by surface heat again and improves, and wearability strengthens.Behind the end wear of long limit, it is just more outstanding that hard, the middle soft situation in both sides embodies.Blade effect (shown in Fig. 4,5) has been played in hard formation zone, both sides 1, and the effect that auxiliary blade forms has been played in the wearing and tearing easily of the zone of middle soft tissue area 2.Thereby in the comminuting matter process, remain two very high blades of hardness and play a role, improved the crush efficiency of beater disintegrating machine significantly.
