Abstract
A kind of rotor type centrifugal roller mill, this equipment is by mantle and decide awl (17) formation coarse crushing section.Also comprise a safety guard with matching, and the improvement part of traction roller.Through the inside lining sleeve (8) of special thermal treatment and the locking and fastener of inside lining sleeve.This equipment can be extensively should be in industries such as building materials, chemical industry, metallurgy grinding to various materials with broken.This equipment volume is little, output is high, power consumption consumption steel is little, easy to use and reliable.
Description
The present invention relates to a kind of centrifugal mill.Rotor type centrifugal ore mill in the past is the centrifugal hoop grinding machine for example, is in series with a plurality of shape one protruding one recessed rotor disks similar to impeller on its main shaft.Rotor disk near around depart from the center and some bearing pins are housed pass the up and down end face of two rotor disks perpendicular to the rotor disk end face.A stone roller ring that endoporus is arranged is being overlapped at this bearing pin middle part, and this endoporus is greater than the bearing pin external diameter, and therefore grinding ring can be free movable in certain scope.A whole set of rotor disk is placed in the inside lining sleeve of a up big and down small stair-stepping heavy wall tubular.When main axis rotation, will drive rotor disk and rotate, and grind ring under the drive of bearing pin around main axis rotation, grind ring under the effect of centrifugal force field, to get rid of to inside lining sleeve simultaneously, at this moment grind ring rotation under the short effect of frictional force.Give fashionablely from top when ore, ore falls by the annular gap between rotor disk and the inside lining sleeve, the rolling of the stone roller ring at this moment will being rolled, and levigate ore is discharged from the bottom at last.
The shortcoming of this machine is: 1, owing to the restriction of grinding ring size, and can not broken coarse granule.Big when 2, grinding ring work to the impulsive force of bearing pin, serious wear.3, no safety guard is handled big iron or other the non-broken body excessively that in the machine that enters equipment is damaged.4, inside lining sleeve easily breaks or weares and teares.5, the installation and removal of milling medium are cumbersome, and equipment fault is frequent.
In order to overcome above-mentioned shortcoming, the invention provides a kind of as shown in drawings new device-rotor type centrifugal roller mill.
According to the present invention, increased by a broken coarse grained device on this machine top.Increased by one and overlapped the safety guard that prevents non-broken body access arrangement.The roller that rolls ore in addition makes the roller dismounting rapidly by an oblique arm-tie and taper pin traction, and the stressed and wearing and tearing of taper pin and roller reduce, and the interchangeability of rotor disk is improved, and is easy to maintenance.
In order to prevent breaking or excessive wear of inside lining sleeve, this machine inside lining sleeve is heat-treated to interior hard outer soft, and the vertical pressing section of inside lining sleeve is made of a screw spring compensation arrangement.
Be the straight profile of weight of rotor type centrifugal roller mill as shown in drawings, this machine is a vertical working, and material is entered by feed pipe (1), by distribution plate (13) get rid of to around.One circle permanent magnetic iron block (2) also is installed around material receiving area, when in the material iron block being arranged, will be adsorbed by it.
By overcoat (12), interior cover (23), bearing (24), in put the one group of screw rod (22) that is circumference uniform distribution, little rigidity disk spring (3), pressing plate (21) and eccentric bushing (11) constituted a mantle.When main shaft (16) fast rotational, because the eccentric bushing and the effect of holding axle, it is very slow that mantle rotates, and mantle and the annular gap generating period variation of deciding between the awl (17).When material that material separating disc is removed under the gravity effect from the annular gap of mantle and fixed awl by the time, the coarse granule that enters wherein will obtain bump and attrition crushing.When excessive non-broken body enters crusher chamber, overcoat will be subjected to a upwards axial force, and this power is compressed spring by pressing plate and screw rod, overcoat just can rise, at this moment the gap between overcoat and the fixed awl increases, and non-broken body is discharged, and mantle resets.At the same time, with the resilient distribution plate of jack-up, distribution plate can touch push rod (14) again in the uphill process of overcoat, and push rod is finally run into lead limit switch (15), at this moment just can cut off the power supply of centrifugal roller mill.
Rubble after the coarse crushing is fallen in the annular gap between rotor disk (10) and the inside lining sleeve (8), and with the rolling and impacting of the roller (9) that is subjected to successively installing, last levigate material is discharged from the bottom.There is a bearing pin inside of roller, the head of bearing pin is welding an oblique arm-tie (6), an oblique arm-tie deep-slotted chip breaker of rotor disk athwart again, tiltedly the other end of arm-tie is hinged by a taper pin (5), this taper pin tapering part cooperates with rotor disk one taper hole, and the axial restraint of taper pin is pushed down by a wedge (4).Rotating speed is higher, and wedge more compresses taper pin.The oblique arm-tie of traction roller can be around taper pin swing in perpendicular to the plane of main shaft in the deep-slotted chip breaker that the rotor disk end face is tiltedly worn.When main shaft rotates, drive the rotor disk rotation, at this moment oblique arm-tie then draws roller and does to rotate in the same way around main shaft.Under centrifugal force field, roller is thrown toward on the inwall of inside lining sleeve (8), and roller is pasting the inside lining sleeve rotation around the axis of self again under the moment of friction effect, and material is rolled in this case and impacts, last levigate discharge.
The inside lining sleeve of centrifugal hoop grinding machine in the past adopts integral quenching often.Easily split when having hardened work, it is easy to wear to have quenched soft.It is considered herein that breaking of inside lining sleeve can not explain and should the fatigue fracture from fracture mechanics illustrate with strength failure.Because the wearing and tearing of inside lining sleeve occur over just the certain thickness (may wear to certain thickness must change) of inwall, therefore it is interior hard outer soft to use suitable way that inside lining sleeve is heat-treated to, so just, can greatly improve the fracture toughness and the fatigability of inside lining sleeve, and can reduce wear again.In order to prevent inside lining sleeve rocking and shake up and down when working, this equipment has improved the quality of fit of inside lining sleeve external diameter tapering place and support (18) internal diameter, its spring compression compensation arrangement is made up of screw rod (7) and spring (19), and it will guarantee that inside lining sleeve is subjected to certain axial pressing force all the time and can become flexible.
The invention provides thus one, to have a volume little, and production capacity is big, can adapt to various abominable conditions, and power saving economizes steel significantly, and the easy grinding attachment of Operation and maintenance.
The present invention be applicable to the industries such as building materials, metallurgy, chemical industry, coal to various materials grind or in small, broken bits.
