Description

Hammer mill

The utility model relates to a kind of disintegrating machine, especially a kind of be applied to occasions such as asbestos ore, lime stone, various metallic ore, gypsum, slag, coal, rock salt and shale in the hammer mill of soft, medium hardness broken and in small, broken bits and brittle material.

The present structure of the disintegrating machine that uses mainly comprises casing, axle, the lay eggs dish and the hammer of laing eggs, and driven by motor belt pulley, Pulley shaft are provided with several dishes of laing eggs, and lays eggs two and coils the center fixed hammer of laing eggs, and the casing two ends are supported Pulley shaft by bearing.There is following shortcoming in the disintegrating machine of this kind structure: one, because casing inside is the desire comminution of material, bearing between casing and the Pulley shaft is difficult for sealing, make to be easy to enter dust in the bearing, thereby bearing very easily damages, generally, disintegrating machine uses about two months just to need to change bearing; Two, in damage of bearings, axle itself also can be levigate, and the time has been grown also and need change; What three, lay eggs hammer is shaped as rectangle, impacts the poor effect of building stones; Four, the casing wearing and tearing are terrible, also need often to safeguard or upgrade.

The purpose of this utility model provides a kind of hammer mill, and its long service life, crushing efficiency height have advantages such as large reduction ratio, low power consuming and operating flexibility are big.

The purpose of this utility model is achieved in that a kind of hammer mill, comprises motor, belt pulley, main shaft, bearing, lays eggs and coil and the hammer of laing eggs, and the bearing on the main shaft is positioned at the outside of casing.

Wall inside at casing is provided with liner plate.

Liner plate is the aside-liner that is located at the casing end face; Or be located at the arc liner plate of cylindrical shell inwall; Or be its combination.

The liner plate inner surface is provided with fin.

The dish of laing eggs is the plum blossom shape.

The hammer of laing eggs is fixed on the dish of laing eggs by four or eight bearing pins.

Employing 65Mn forges the hammer of laing eggs that forms and is trapezoidal.

Top at casing is provided with feeding mouth, and Qi Bishang is provided with striker plate; Be provided with sieve plate and discharging opening in the bottom of casing.

On main shaft, be provided with flying wheel.

Be cast with fin on the liner plate made from high manganese steel sheet.

Therefore the utility model has solved the problem that the prior art middle (center) bearing enters dust because bearing is positioned at the outside of casing, needn't often change bearing, reduces cost, and reduces the workload of safeguarding; Owing to be provided with higher aside-liner of intensity and arc liner plate in casing inside, reduce the maintenance work of casing, change conveniently, and the liner plate inwall all is rough and uneven in surface shape, therefore also can assist to impact building stones; Dish adopts the plum blossom profile owing to lay eggs, and the material saving also can be played the effect of assisting to smash building stones on the other hand on the one hand; Because it is trapezoidal that the shape of tup adopts, make to impact the efficient raising; Owing to increased flying wheel, increase impacts efficient.

Fig. 1 is a sectional side view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the structure chart of laing eggs and coiling;

Fig. 4 is the structure chart of laing eggs and hammering into shape.

As shown in Figure 1, 2, the utility model mainly comprise main shaft 16, the dish 5 of laing eggs, lay eggs hammer 4, arc liner plate 9, bearing 3 and flying wheel 7.

On main shaft, be with belt pulley 1, bearing 2, casing 15, aside-liner 13 successively, lay eggs dish 5, aside-liner 13, bearing 2 and flying wheel 7, bearing 2 is fixed on the frame 10 by bearing block 2, bearing 2 is positioned at the outside of cylindrical shell 15, cylindrical wall inside at casing is provided with arc liner plate 9, end face at casing is provided with aside-liner 13, liner plate is fixed on the casing with bolt 6, and all replaceable and its inner surface of arc liner plate 9 and aside-liner 13 is provided with fin, can play the auxiliary effect that impacts building stones.Between two aside-liners, coil 5 for being laing eggs of plum blossom shape, the rim axis direction of laing eggs is provided with several grooves, by four bearing pins that 4 hammers of laing eggs are fixed thereon in each groove, the hammer of laing eggs is trapezoidal, adopting 65Mn to forge forms, the hardness height, wear-resistant, steel consumption is low, it is shaped as up big and down small, this shape makes its hammer effect the best, most effective.

Be provided with feeding mouth 8 on the top of casing 15, Qi Bishang is provided with striker plate 12; From then on building stones enter the inside of casing 15 and liner plate, and along with the rotation of main shaft, the building stones hammering of being laid eggs is broken, is provided with sieve plate 14 and discharging opening 11 in the bottom of casing 15, and the building stones that smash are promptly discharged from discharging opening 11 when its external dimensions during less than the hole on the sieve plate 14; Greater than the building stones in hole on the sieve plate 14 once more through the impact of the hammer of laing eggs, grinding, extruding and fragmentation, at last also from discharging opening 11 discharges.

In order to increase the rotary inertia of main shaft, improve the efficient that impacts of the hammer of laing eggs, on main shaft, be provided with flying wheel 7.

In sum, casing adopts the split pattern, easy accessibility, and overhaul, replacing is laid eggs etc. needs only slings upper housing saving of labor, the laborsaving recondition expense of can saving again; Casing is inner to be used and has high manganese steel sheet and make liner, has advantages such as hardness height, anti-wear performance are good, is cast with fin on the liner plate in order to improve the ratio of reduction and crushing efficiency, the consumption of reduction energy; Bearing is overhanging type installation form, and is lubricated more convenient, and dismounting, changes easily, adopts labyrinth sealing between casing and the bearing, guarantees the bearing indoor cleaning, thereby prolonged the service life of bearing.
