Centrifugal crusher is widely used in sandstone production line, metallurgical, colliery, ore dressing, the industries such as building materials, traditional centrifugal crusher has the rotor of a High Rotation Speed centered by vertical axis, the broken raw material of putting in this rotor is discharged at a high speed from a plurality of outlets that are opened in rotor surrounding under the effect of the centrifugal force of rotor generation, then collide in the crushing chamber of peritrochanteric and be broken into fine grained on formed material lining, in order to improve crushing efficiency, in the surrounding of rotor, give prominence to and be provided with fixing material casting hammer, its smashing principle is, the broken raw material of discharging from the outlet of rotor is broken after striking material casting hammer, material casting hammer is fixed on the external margin of rotor, when rotor is around rotating shaft during with certain rotary speed High Rotation Speed, if dropped into while having material that particle diameter is larger or the larger hard objects of other particle diameters in the raw material of this centrifugal crusher, because this material is zero in the component velocity of material casting hammer direction of rotation, differ larger with the speed of material casting hammer, therefore this material is to rotor moment generation greater impact, cause rotor wearing and tearing aggravation to affect rotor life, even cause coming off of material casting hammer.While causing that due to outside cause the inventory of input centrifugal crusher changes in addition, also for causing that falling material produces greater impact to material casting hammer, causes coming off of material casting hammer.Simultaneously traditional centrifugal crusher when rotated, at the inner rotary wind being more or less the same with the same direction of rotor and speed and material casting hammer speed that forms of crushing chamber, causes rotor crushing efficiency step-down,
There is following problem in existing centrifugal crusher:
The one, in crushing chamber, material casting hammer has been brought into play blade function, follows rotor high-speed rotation, forms and hammer into shape in same direction with material casting and rotary wind that wind speed and material casting hammer speed are more or less the same in crushing chamber.Broken raw material is more or less the same in the speed that lower speed and material casting hammer into shape of carrying of rotary wind, the effect reduction that is broken of broken raw material;
The 2nd, when the raw material supplying amount of input disintegrating machine changes suddenly or has the raw material input disintegrating machine of greater particle size, when the material casting hammer of the High Rotation Speed being fixed together with rotor frame is subject to unsettled impacts, understanding rotor vibrates, material casting hammer is come off or accelerate the wearing and tearing of material casting hammer, the service life of reducing rotor;
The 3rd, when improving the output of centrifugal crusher, need to add trochiterian diameter, increase the power of drive source.
Utility model content
In order to overcome the deficiency of existing disintegrating machine, the utility model provides a kind of crushing efficiency high, long service life and can realize the energy-conservation disintegrating machine of disintegrating machine drive source, comprise rotor and for carrying the disintegrating machine of this rotor, it is characterized in that: described rotor comprises rotor body, rotor top plate, rotor base plate, thrower head and material casting hammer device, described rotor top plate and rotor base plate are installed on rotor body, rotor top plate is parallel with rotor base plate and keep at a certain distance away, and between rotor top plate and rotor base plate, forming more than three discharging openings, described thrower head is made by hard material, be installed on the end of each discharging opening, described material casting hammer device comprises the hammer body fixed mechanism being installed on rotor base plate, swingable be installed on the material casting hammer body on hammer body fixed mechanism, this hammer body fixed mechanism is arranged at discharging opening place and is arranged in rotor periphery, material casting hammer body is along with rotor revolution also can swing around hammer body fixed mechanism, and the striking face of material casting hammer body is towards the rotor top plate that protrudes from of vertical direction.
Further, hammer body fixed mechanism and material casting hammer body removably connect.
Further, hammer body fixed mechanism comprises holder, swing arm and arm shaft, and this holder at right angle setting joins on rotor base plate and with rotor top plate, and arm shaft is arranged on holder, swing arm is connected with holder by arm shaft and can swings around holder, and material casting hammer body is installed on swing arm end.
Further, material casting hammer body and swing arm are Split type structure, or one-body molded with swing arm.
Further, the outer rim at rotor base plate is given prominence in swing arm, and the crusher chamber inwall of material casting hammer body and disintegrating machine leaves certain spacing and material casting hammer body bottom to downward-extension.
Further, the rectangular shape or polygon or the toroidal that are shaped as perpendicular length of the striking face of material casting hammer body.
Further, swing arm is one or more.
Further, swing arm be shaped as bar-shaped or be fusiform section configuration or be perforate structure can breathe freely tabular.
From above-mentioned, to description of the present utility model, the disintegrating machine that the utility model provides, significantly improves crushing efficiency, realizes the energy-conservation of disintegrating machine drive source; Improve crusher rotor and when High Rotation Speed, resist the ability that raw material changes suddenly that drops into, the service life of improving disintegrating machine.
