Description

Gyratory crusher

The present invention relates to a garden conic crusher, in the crusher surface of a hollow taper on stator, the broken garden awl of taper type is done to roll or oscillating motion, gap width between broken garden awl and the stator hollow garden awl and the stator hollow taper plane of disruption can be changed by the axial displacement of broken garden awl, it should be noted the in succession tapering point of broken garden awl of the extension of axle, it is bearing in the bearing that is installed on the stator and can does to roll or swing.In such garden conic crusher, be present in slit around the broken garden awl between the awl of the hollow taper plane of disruption of stator and broken garden because rolling or swinging of cone is reduced to minimum widith, the broken size of material granule has afterwards been determined in the slit of this minimum widith.This crack is wide to be that position after broken garden awl by supposition rises produces.Up to the present, determine this lifting position and draw thus crack is wide still has any problem.Up to now, the extreme lower position and the extreme higher position of broken garden awl are to determine with final position and required lifting position, therefore up to the present required particle size can only be selected with a kind of method of danger, and the way of promptly using the adjustment amount of movement that begins from final position to regulate the lifting position of broken garden awl is selected.Can not accurately regulate the size of broken back material granule in this way.

In conventional device, or measure the oil level of the hydraulic reservoir be used to regulate this disintegrating machine, the measured value of gained is inaccuracy very; Or be used in and regulate the displacement transducer of installing in the cylinder and measure under latter event, dismounting and assembling are all very expensive during maintenance.Because displacement transducer is contained in the cylinder compresses space that the high pressure collision takes place, so responsive especially to fault.

One object of the present invention just provides the possibility of regulating broken back material granule size in a simple manner.In order to solve this task, the width of to the effect that determining the slit of the present invention with the lifting position that acts on the broken garden of the displacement sensor awl on the awl of broken garden.In this method, determine that the particle size of broken back material is possible thereby regulate raised position according to the measured value that displacement transducer provides.Drive unit acts on the lower end of the axle of broken garden awl, makes broken garden awl make eccentric motion, and the rise of broken garden awl then utilizes a stressed sizable piston-cylinder assembly to realize.Position of piston can not be determined still to be difficult in other words determine at once in piston-cylinder assembly.The axle of broken garden awl is arranged in a cell of eccentric driving device scope, crushing material this chamber of flowing through.Do not make this fact of violent eccentric motion even if do not consider axle like this in this scope, only displacement transducer being installed in also is difficult in this cell.So according to the embodiment of a recommendation of the present invention, displacement transducer acts on the extension of axle.Less warp-wise motion is only done in this extension, makes a point of contact that is used for detector for displacement measuring that is contained in this position in fact produce real measured value.Mechanical type displacement transducer more complicated because this extension be positioned at the garden conic crusher reinforced the space of process.Its reading shows difficulty.The embodiment of another recommendation according to the present invention, displacement transducer are electric displacement transducers, particularly an inductance type or capacitive displacement transducer.The measurement result of this displacement transducer can be seen clearly without difficulty.

Link to each other with the extension of axle with plug type armature of embodiment of a recommendation according to the present invention and insert a motionless element of displacement transducer, particularly in winding.Owing to plug type armature is for a fixing element that inserts displacement transducer disposes, so the stationary element of electric conductor tube and this displacement transducer can be connected in a simple manner.

According to the present invention, the mode that displacement transducer element that is connected with the extension of axle rotates with the direction less tumbling motion in the scope of the extension of axle like this can be compensated.For same purpose, according to the present invention, it is suitable that displacement transducer element that is connected with the extension of axle is made by a flexibility bar.

According to the example example of a recommendation of the present invention, the detector for displacement measuring point of contact on the prolongation of axle is positioned at the oscillation center that bore in broken garden approx.If this shock point accurately is positioned at the oscillation center of this fragmentation garden awl, a prolongation that can displacement transducer be connected in spool with a kind of mode that allows universal movement just.Yet broken garden awl can be regulated in short transverse, and this makes the point of contact and the oscillation center of the extension top offset sensor of axle is not to bore all lifting positions all accurately to overlap in broken garden.In this case, can carry out required correction with flexibility bar.The extension of the axle of broken garden awl is bearing in the bearing, and oscillation center is just in the scope of this bearing.For point of contact being arranged near the oscillation center of broken garden awl, according to the present invention, the point of contact of displacement transducer on the extension of axle should be positioned at the centre bore of this extension, and a part that it should be noted that displacement transducer at least is preferably also in this centre bore.

According to the present invention, if displacement transducer is contained in the sleeve, this sleeve insert in the centre bore of extension of axle and its fixed-site in the extension of axle, then structure and assembly manipulation are simple especially in this case.According to the present invention, an insert can insert from the base of sleeve, the bearing that a median rise is arranged in the chamber of this insert, the displacement transducer element that links to each other with the extension of axle is bearing in this bearing, it is hinged in the mode of cardan axis, can not move axially, it should be noted and filled viscous liquid in this loculus, (particularly oil) and with a flexible plate closure tip.Consequently assembly manipulation is especially simple, and owing to fill viscous liquid in this chamber, therefore produces good damping effect.If this viscous liquid is an oil, then the lubricated of the bearing of median rise also solved.

According to the present invention, around central authorities preferably adorn one in the stator sealing and with the rigidly connected casing of stator.This casing is loaded with the bearing used of extension of axle and surrounds displacement transducer, it is to be noted especially between the top of this casing and stator to treating the reinforced space that an annular is provided of crushing material.So just produced the structure of a sealing, displacement transducer is protected therein and the crushing material for the treatment of that can not be added into damages.Must pass through this annular space owing to be used for the electric conductor tube of detector for displacement measuring; and treat that broken material is also by adding here; therefore; according to the present invention; in this annular gap district; this electric conductor tube should be installed in the armouring pipe, and this armouring pipe is preferably again with a top cover protection.

In the accompanying drawings, by an embodiment the present invention is done the explanation of summary.
