Abstract

The utility model relates to a vertical shaft counterattack type fine crusher which is combined by an upper rotor, a middle rotor and a lower rotor, wherein, the cones of the rotors all have a conicity of 1: 5. The upper rotor and the middle rotor are respectively fixed with 8 grooved impact plates and 8 grooved armoring plates, and the end faces of the upper rotor and the middle rotor are fixed with two slinger disks that are oppositely grooved. The impact plates of the upper rotor and the middle rotor mutually present an interlaced angle of 22.5DEG, the cone of the lower rotor is fixed with 4 corrugated lining plates whose laevorotation helix angle is 8DEG, and the corrugated lining plates integrate circular arc shapes and cylinder shapes. The upper end face of the corrugated lining plate is fixed with 2 slinger disks that are oppositely grooved, and the three rotors are all partitioned by distance sleeves.

Description

Verticle shaft and back shock fine crusher

The utility model provides a kind of vertical shaft reaction type fine crusher, belongs to mechanical field.

Horizontal and the standing crusher of present common use is broken insufficient to material, and the ratio of reduction is little, and granularity is difficult for guaranteeing that energy consumption is big that the maintenance difficulty is big.

The purpose of this utility model provides a kind of efficient, energy-conservation vertical shaft reaction type fine crusher, make material in crusher chamber, fully be subjected to continuously, repeatedly, strong strike, counterattack, push, mill, rub with the hands cut and collide fragmentation after, reach super fine crushing, and capacity usage ratio height, crusher structure is simple, and is easy to maintenance.

The utility model purpose is to be fixed on rotor on the main shaft by the motor drives that following manner realizes, rotor is combined by more piece, and rotor awl tube is the tapering of 1:5.Last joint, middle joint rotor are fixed 8 plough groove type beater plates and 8 plough groove type backplates separately, and fix 2 separately and split the plough groove type batch mixing pan in last joint, middle joint rotor upper surface, interlaced 22 ° 30 ' of last joint, middle joint rotor beater plate, saving rotor awl tube down, to fix 4 left-handed helical angles of forming one by garden arc and garden cylindricality be 8 ° ripple liner plate, the upper surface is fixed 2 and is split the plough groove type batch mixing pan, and three joint rotors separate by spacer.Material enters and drops on going up on the joint rotor batch mixing pan of rotation at a high speed by feed hopper (2), high speed rotation through batch mixing pan is hit, material is thrown to counterpunch board, fragmentation hits back, strike back on plough groove type beater plate (4) and the backplate (5) by counterpunch board again, hit back broken material under bounce and gravity synergy, feeding downwards, carry out continuously, repeatedly, hit, the counterattack and material between strong collision and carry out fragmentation, break away from then and go up the joint rotor, drop on the middle joint rotor batch mixing pan of rotation at a high speed, material is quickened to hit by level again, and throw to counterpunch board, fragmentation hits back, thereby delayed blanking speed, increase the disintegrating machine meeting, and change material traffic direction increases the collision probability of material, when material carries out in middle joint rotor hits the zone continuously, repeatedly, strong strike, after counterattack and the collision fragmentation, fall then on the following joint rotor batch mixing pan of rotation at a high speed, material is quickened to hit and throw to counterpunch board by level once more, fragmentation hits back, thereby delay blanking speed once more, increase the disintegrating machine meeting, change the material traffic direction, between band is by the following joint rotor (7) of circular arc and the cylindrical ripple liner plate of forming (6) and counterpunch board, carry out continuously, repeatedly, strong strike, extruding, mill, after stranding is cut and is collided, reach certain particle size, the slit that breaks away between counterpunch board and the rotor ripple liner plate (6) enters hopper (8), discharges cavity by hopper.

Concrete structure of the present utility model is seen shown in the accompanying drawing:

Figure (one) is the primary structure schematic diagram of disintegrating machine;

Figure (two) saves the rotor structure schematic diagram down for disintegrating machine;

Figure (three) is a disintegrating machine beater plate structural representation;

Figure (four) is last, rotor plough groove type guard board structure schematic diagram;

Shown in the figure (): the 1st, motor 2 is that feed hopper 3 is that cylindrical shell 4 is that beater plate 5 is that backplate 6 is that ripple liner plate 7 is that joint rotor 8 is hoppers down

The course of work of this machine is: motor (1) drives main shaft, rotor rotates with main shaft one superhigh speed, material enters the inner chamber of cylindrical shell (3) from feed hopper (2), through the more piece rotor continuously, repeatedly, strong strike, counterattack, push, mill, rub with the hands cut and collide fragmentation mutually after, reach certain particle size, the inner chamber that breaks away from cylindrical shell (3) is at last discharged by hopper (8).

Good effect of the present utility model is: this machine makes the mutual collision frequency height of material, and the ratio of reduction is big, and broken fineness is little, can improve mill output 20～30%, the capacity usage ratio height, and simple in structure, easy to maintenance.

Claims

1, a kind of vertical shaft reaction type fine crusher is by motor (1), feed hopper (2), cylindrical shell (3), beater plate (4), backplate (5), ripple liner plate (6), save rotor institutes such as (7) down and form; It is characterized in that fixing on following joint rotor (7) the awl tube 4 left-handed helical angles of forming one by garden arc and cylindricality and be 8 ° ripple liner plate (6), the upper surface is fixed 2 and is split the plough groove type batch mixing pan.

2, disintegrating machine according to claim 1 is characterized in that rotor is combined by more piece, and rotor awl tube is the tapering of 1:5, and three joint rotors separate by spacer.
