Description

A kind of rotary breaker

Technical field

The utility model relates to a kind of rotary breaker.

Background technology

Rotary breaker claims bradford breaker again, is made up of cylinder, supporting arrangement, transmission device and frame four parts substantially.Cylinder is made up of rolling ring, combination beam, sieve plate and riser.At the circumference of two rolling rings, the certain angle combination beam is connected to form the tubular framework at interval, and fixed screen deck constitutes drum sieve on the framework; At the axial installation riser of the inwall interval of drum sieve certain angle along cylinder.Supporting arrangement generally is the carrying roller that is fixed on the frame, and the distance between wherein a pair of carrying roller can be adjusted, and regulate to adjust screw rod, the distance between axles of two carrying rollers is diminished or becomes big, thereby make the angle increase of tubular axis and horizontal plane or dwindle.Transmission device is distinguished to some extent according to the difference of the kind of drive: as be the friction transmission, then two carrying rollers of cylindrical shell one side play initiatively friction wheel, are driven by a decelerator and a major axis by motor, and initiatively friction wheel drives the cylinder rotation by friction; If cylinder is longer, also available two motor drive two carrying rollers by two decelerators respectively, make its frictional drive.Gear drive in this way, motor drives pinion by decelerator, and pinion and the bull gear engagement that is contained on the cylinder rotate cylinder.Chain gear transmission is that motor drives minor sprocket by decelerator, drives the hinge wheel that is fixed on the cylinder again by chain, and cylindrical shell is rotated together.Basically rollers roll is assemblied on the transmission device on the frame.When adjusting cylinder axis and horizontal plane angle, also can take on support, to install the device of transferring the inclination angle, realize by the angle of inclination of adjusting frame.

Many at present the special equipments of rotary breaker as broken coal.During work, raw coal is sieved in advance so that smalls is sifted out.Behind the feed, along with cylinder rotates, feed coal cinder and be raised plate and mention, forward certain angle to, coal cinder freely falls from eminence along riser.Cylinder constantly rotates, and coal cinder is raised repeatedly and falls, and in this process, coal cinder is by bump and fragmentation, and saturating sieve discharges, and bulk spoil, metal sundries and the wooden unit etc. that are not broken are then discharged through sieving from the discharge funnel.Its operation principle is to utilize coal can fall the different of fragility with spoil, and coal falls voluntarily and is hit and broken, and granularity is separated with bulk through screening simultaneously less than the coal cinder of sieve aperture, and last bulk spoil or metal sundries etc. are discharged from the other end of cylinder screen drum.

But being to use this rotary breaker mainly is to utilize to fall the fragility difference between different material, therefore requires storeroom can fall the fragility significant difference, and product does not require the reservation bulk, also must tell in advance for the bulk spoil, in order to avoid smash sieve plate after entering disintegrating machine.Therefore present rotary breaker narrow application range, service condition are relatively harsher.

The utility model content

The purpose of this utility model is to provide a kind of rotary breaker, can be applicable to more occasions, increases work efficiency simultaneously.

The technical solution adopted in the utility model is as follows:

A kind of rotary breaker comprises cylinder, supporting arrangement, transmission device and frame, and rollers roll is assemblied on the transmission device on the frame, and cylinder comprises rolling ring, sieve plate and riser, week upwards evenly rotates to be provided with at interval in the cylinder to impact tup.

Rotary breaker described in the utility model is week upwards evenly to rotate to be provided with at interval in cylinder to impact tup on the common broken basis of selecting machine.Brokenly select machine when work, the material that is broken feeds broken the choosing in the machine cylinder uniformly through artificial or plant equipment, and the sieve plate of the band riser of rotary cylinder body and circumference leans on material and its frictional force that material is taken up.After treating that cylindrical shell forwards certain angle to along the axle center, material freely falls by gravity.Under the effect of weight of material own and acceleration force, different materials is produced different impulsive forces, the hardness thing grain bump material soft that big grain (piece) degree is bigger than small grain size, small grain size is crashed to pieces, peels off granularity and diminishes, granularity is more and more littler under the material that goes round and begins again continuous impacts, because the rotation centerline and the horizontal line of cylindrical shell have an angle, the rotation material of cylindrical shell just moves forward certainly by the position of gravity fall.Soft material is raised, lands, moves, and many times be subjected to impact, friction, granularity diminish gradually.To material be broken, be ground into granularity less than the slit of sieve aperture after under the effect of the stressor layer of material, impulsive force, vibration force, expelling tube is external, collect and transport to down road production workshop section through conveying machinery equipment through the rewinding case, and these are consistent with common rotary breaker working mechanism; But impact tup owing to increased, in the cylinder rotating process, tup also rotates thereupon, in this process, impact that tup impacts material and broken, help only depending on the fragmentation that gravity can't pulverized larger particles, for fall could broken material by repeatedly promoting, also can quicken its pulverizing, improve operating efficiency generally.Because size, the number of tup are adjustable, therefore can come brokenly to select different materials, and be not limited only to fall the bigger material of fragility difference by adjustment to these parameters; Add that broken material grain (piece) degree that selects machine to handle of the utility model is also general broken to be selected confidential greatly, simplified preliminary treatment material.

Preferably, the distribution density of tup on the drum length direction is for to be successively decreased gradually to the waste outlet end by feed end, the feed end distribution density helps material greatly to be pulverized as early as possible, and the tup near the port of export on the drum length direction has been a supplementary function, so density should not be too big.Concrete condition should be considered drum length, and the tup number is too much unsuitable, too much is unfavorable for the startup of equipment; Further,, be provided with pre-screen drum,, can directly collect from pre-screen drum for the material that granularity meets the demands at described cylinder feed end in order to alleviate the live load of cylinder.

The mounting means of riser is with existing rotary breaker, and what the utility model adopted is the parallel installation with cylinder axis of riser, and tubular axis and horizontal plane have certain angle; Purpose is when guaranteeing the material drop number, makes material as early as possible outside the expelling tube.Concrete, the angle of tubular axis and horizontal plane can be regulated by the angle of inclination that frame was regulated or adjusted to supporting arrangement.Rotary breaker cylindrical shell revolution is to be advisable between 10～15r/min.

The utility model has following advantage with respect to prior art:

Described rotary breaker is simple in structure, has functions such as fragmentation, screening, autogenous grinding, not only adapts to the broken choosing of mineral products such as Peng Run soil, coal, also be applicable to selecting of foreign material in the various nonmetallic ores, stone, applied widely, high efficiency, disposal ability can reach 18-25t/h.
