Abstract

The utility model discloses an ultra-micro crusher hammer in the field of the fed machine, which aims at solving the problems that the consumption of the raw material is large, and the rejected abrasion-resistant material is vast of the prior hammer when in invalidation, and comprises a hammer main body, wherein one side surface of the hammer main body is of a striking surface, the hammer main body is provided with at least two installation holes, the connection line between the centers of the two installation hole is vertical to the striking surface, and the width side surface of the hammer main body which is opposite to the striking surface is smaller than that of the striking surface. The hammer reduces the consumption of the material, reduces scrap of the abrasion-resistant material after the hammer is abraded and loses effectiveness, saves electric energy, and improves the yield.

Description

A kind of micronizer tup

Technical field

The utility model relates to a kind of pulverizer of grain feed mechanical field, particularly a kind of micronizer tup.

Background technology

Generally use vertical ultrafine disintegrator that high-grade aquatic feeds is carried out ultramicro grinding processing in the feed processing industry, grinding particle size is generally at 60 orders～200 orders.

Be provided with gear ring, grating disk and other parts in the pulverizing chamber of vertical ultrafine disintegrator, grating disk is equipped with a plurality of tups near on the circumference of gear ring.During pulverizer work, grating disk drives the rotation at a high speed in gear ring of each tup, and material will be delivered to tup under action of centrifugal force, and tup is pulverized in the mode of hitting at a high speed material.Tup is also thrown to gear ring with material simultaneously, and material and gear ring bump are subjected to further pulverizing.In micronizer, tup plays main pulverization, and gear ring plays auxiliary pulverization.

The tradition tup comprises the tup body, and a side of tup body is the scope of attack, and the tup body is provided with two installing holes, and the line at two installing hole centers is parallel to the scope of attack, and two bights of the scope of attack are for hitting the angle.As shown in Figure 1, the scope of attack of each tup is that the center of circle is radial distribution with the grating disk center, be fixed on the grating disk by two installing holes, the line at tup two installing hole centers is parallel to scope of attack setting, the line that is tup two installing hole centers is that the center of circle is radial arrangement with the grating disk center also, makes the scope of attack compare broad.

In real work, when tup rotated at a high speed, two of the tup scope of attack hit angles and shoulders main strike and pulverize task, so two the hitting angles and can be worn and torn in advance of the tup scope of attack, and the wearing and tearing of scope of attack middle part are slower.After two strike angles of the scope of attack were worn, although the wearing and tearing as yet of the scope of scope of attack middle part broad still need more to renew tup, and tup perhaps paste the weldering high-abrasive material generally with expensive high-abrasive material making on the tup scope of attack, cost was higher.Therefore, when traditional tup was scrapped, residual volume was bigger, and the waste loss of high-abrasive material is very big.The scope of attack broad of tup makes that the windage that is subjected in the running is also bigger simultaneously, has not only increased power consumption, has also influenced the output of pulverizer.

The utility model content

The technical problems to be solved in the utility model is, a kind of micronizer tup is provided, and guaranteeing to hit under the prerequisite of smashing capability, reduces the learies of high-abrasive material behind the tup wear out failure.

For solving above technical problem, the technical solution of the utility model is that a kind of micronizer tup is provided, comprise the tup body, a side of tup body is the scope of attack, and the tup body is provided with at least two installing holes, and the line at installing hole center is perpendicular to the scope of attack.

The technical program has following beneficial effect with respect to prior art: the line at installing hole center under the situation that keeps two strike angles, has dwindled the width of the scope of attack perpendicular to the scope of attack, reduced the consumptive material of tup, make that when losing efficacy, the high-abrasive material that residue is scrapped is less, has reduced waste; The windage that the while tup is subjected in the running is also less, has reduced power consumption, has improved the output of pulverizer.

As improvement of the present utility model, on the described tup body with the width of scope of attack opposite flank width less than the scope of attack.Can further reduce the consumptive material of tup, make the strike angle become littler acute angle simultaneously, improve strike effect.

Fig. 2 is the structural representation of the utility model micronizer tup.

Fig. 3 is the scheme of installation of the utility model micronizer tup on grating disk.

Fig. 4 is the stereogram of Fig. 3.

Among the figure: 1 gear ring, 2 tups, 2a bolt hole, the 2b scope of attack, 3 grating disks, 4 materials.

The specific embodiment

As shown in Figure 2, the utility model micronizer tup comprises the tup body, the side of tup body broad is scope of attack 2b, the tup body is provided with two bolt hole 2a as installing hole, the line at installing hole center is perpendicular to scope of attack 2b, and the tup body is fixed on the grating disk 3 by two bolt hole 2a.The cross section of tup body is trapezoidal, promptly with the width of the scope of attack 2b opposite flank width less than the scope of attack.

As shown in Figures 3 and 4, each tup is installed in grating disk 3 near on the circumference of gear ring 1, and its scope of attack 2b is that the center of circle is radial distribution with the grating disk center, and promptly the line at two bolt hole 2a centers is along the circle distribution of grating disk 3 near gear ring 1.

During work, grating disk 3 drives the rotation at a high speed in gear ring 1 of each tup, and material 4 will be delivered to tup under action of centrifugal force, and the scope of attack 2b of tup pulverizes to hit at a high speed material 4, tup is also thrown to material gear ring 1 simultaneously, and material 4 is subjected to further pulverizing with gear ring 1 bump.Through test, tup of the present utility model is guaranteeing that consumptive material has descended 30～40% than original tup under the strike smashing capability and the prerequisite in service life.Simultaneously,, reduced windage, made the production capacity of micronizer improve about 10% because the scope of attack of tup shortens.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.

Claims

1. a micronizer tup comprises the tup body, and a side of tup body is the scope of attack, and the tup body is provided with at least two installing holes, it is characterized in that, the line at installing hole center is perpendicular to the scope of attack.

2. a kind of micronizer tup according to claim 1 is characterized in that, on the described tup body with the width of scope of attack opposite flank width less than the scope of attack.
