The single-roller crusher comprises a rack; the rack is provided with a rotary main shaft; a plurality of tooth rollers with single teeth are ranked on the main shaft; a plurality of single teeth are uniformly distributed along the peripheries of the tooth rollers; an alloy hammer head is fixed on the top side surface of each single tooth; the main shaft is supported to bearing seats at two sides of the rack, and is driven by a driving mechanism and a speed reduction mechanism; in the drive directions of the tooth rollers, from the second tooth roller, the tooth rollers are installed by deviating from the adjacent former roller at a certain equal angle; the deviation angle is equal to the value obtained by dividing an included angle between two single teeth on the tooth rollers by the quantity of the tooth rollers. Under the premise of guaranteeing the high-temperature resistance and abrasion resistance of the device, more attention is paid to research on the service life of the device; through changing the installation angles of the ranked tooth rollers, the axial force is very uniform, the phenomenon of shaft cracking caused by nonuniform stress between the axial force and the radial force is reduced, the main shaft stress is improved, the service life of the main shaft is prolonged, and further the whole service life of the device is prolonged.
Description
technical field
The present invention relates to a kind of steel works sintering ore deposit cake disintegrating apparatus, i.e. single roll crusher.
Background technology
In the prior art, single roll crusher is widely used in the industries such as iron and steel, metallurgical mine and is applicable to hardness coarse fodder in fragmentation, and the red-hot sintering deposit cake that is generally used for sintering machine is unloaded carries out fragmentation, makes red-hot break of sinter cake become to be applicable to the granularity of cooling requirement.During the fifties in last century, the disintegrating machines such as the matching used HKM type of sintering machine.Squash type rod-toothed crusher for general fractured rock.Its major defect comprises that crushing efficiency is low, and granularity is inhomogeneous, leaks material etc.After the eighties, the matching used disintegrating machine of sintering machine changes shearing monodentate disintegrating machine into, and main feature is that grate plate is placed on bottom, and discaling roll inserts in grate plate, and nugget is sheared between discaling roll and grate plate, and crushing efficiency is high, and epigranular has been eliminated and leaked the material phenomenon.
Single roll crusher is commonly called as the jaw roll crusher, comprise hopper, rotating spindle in hopper, be placed with a plurality of discaling rolls with monodentate (being that discaling roll is comprised of a plurality of monodentates that are uniformly distributed along the circumference on lining and lining) on rotating spindle, discaling roll is generally 5-11,3-4 monodentate arranged on each discaling roll usually, on each monodentate point side, be fixed with the alloy tup, the monodentate point stretches out forward as the olecranon shape.The spindle face of single roll crusher is facing to jaw.Main shaft supporting is on the bearing block that is loaded on the frame two side, and main shaft is driven by driving mechanism, reducing gear.In single roll crusher when work, only have the main shaft rotation, and the material piece feeds from loading hopper, between jaw and monodentate point, is subject to shear action, and be subject to the impact of monodentate point and slabbing action and pulverize.
In on-the-spot feedback information for many years, single roll crusher is except the discaling roll wearing and tearing, and the damage of axle accounts for second.General cracker teeth roller is all that upper level becomes the rotation of 60 ° with next stage, make axle in the process of rotation for a long time 30 °, 90 °, 150 °, 210 °, 270 °, 330 ° totally 6 impact maximums that extreme point is subject to, thereby cause the inhomogeneous of axial force, make axle fracture, reductor damages, and burning electric motor etc. affect service life of equipment.
Summary of the invention
The objective of the invention is provides a kind of main shaft that improves stressed for above-mentioned deficiency, the single roll crusher of long service life.
Technical solution of the present invention is: a kind of single roll crusher, comprise frame, rotating spindle is arranged on frame, be placed with side by side a plurality of discaling rolls on main shaft, be uniformly distributed with a plurality of monodentates on discaling roll along the circumference, be fixed with the alloy tup on each monodentate point side, main shaft supporting is on the bearing block that is loaded on the frame both sides, main shaft is by driving mechanism, reducing gear drives, it is characterized in that discaling roll is from transmission direction, evenly being offset certain angle since second relatively previous discaling roll of each discaling roll of discaling roll installs, deviation angle is equal to or less than on discaling roll angle between two monodentates divided by discaling roll quantity.Its numerical value equals or is slightly larger than or is slightly less than or approach divided by the numerical value obtained.As deviation angle (take the discaling roll number as 5-11,3 monodentates are arranged on discaling roll, interval 120 degree are example) is 24 °, 23 °, 22 °, 21 °, 20 °, 19 °, 18 °, 17 °, 16 °, 15 °, 14 °, 13 °, 12 °, 11 °, 10 °.Deviation angle is not limited to this, can also be the number of degrees that approach of the front number of degrees, need not require very accurate.
In such scheme, discaling roll quantity is six, and three uniform monodentates are arranged on each discaling roll, and discaling roll, from transmission direction, is evenly installed at skew 20 degree angles since second relatively previous discaling roll of each discaling roll of discaling roll.
In such scheme, discaling roll quantity is seven, and three monodentates are arranged on each discaling roll, and discaling roll, from transmission direction, is evenly installed at skew 17 degree angles since second relatively previous discaling roll of each discaling roll of discaling roll.
In such scheme, discaling roll 4 quantity are seven, and three monodentates 3 are arranged on each discaling roll 4, and discaling roll 4, from transmission direction, is evenly installed at skew 15 degree angles since the relatively previous discaling roll 4 of second discaling roll, 4 each discaling roll 4.
In such scheme, the alloy tup is connected with monodentate by bolt, is convenient to change.
This single roll crusher (6,7,7 tooth) generally be used in the broken bulk heat sinter cake temperature drawn off from sintering machine up to≤450 ℃ (Non-water-cooleds) to 1000 ℃ (water-cooleds), in the environment of many dirt, work.In every part of broken regional work, all by high temperature resistant, wear-resistant material, made, to meet the normal use of single roll crusher.And in order to extend its service life, except select quality material or surface overlaying heat-resisting, wear-resisting hardened layer, also adopted logical water-cooled structure.Its pattern comprises that main shaft, bearing block, crown and grate plate all apply water cooling.
Advantage of the present invention is: under high temperature resistant, the wear-resistant prerequisite of assurance equipment, more focus on the research to service life of equipment, by the change discaling roll setting angle of arranging, make discaling roll change into monodentate by the original multiple tooth while stressed (main shaft being impacted large) stressed, the formation staged is sheared, crushing effect is good, to main shaft, impact also little, thereby it is stressed to have alleviated main shaft, make axial force very even, reduced discontinuity between axial force and radial load and made the phenomenon of axle fracture, improve main shaft stressed, improved the main shaft life-span.Movable alloy tup is replaceable has extended complete machine service life; Staged is sheared and have been reduced the impulsive force of sintering deposit to main shaft, accordingly reductor is impacted also and reduces, thereby improved reductor service life.Staged is sheared can reduce induction-motor load, reduces the generation of the excessive burning electric motor situation caused of immediate current.Comprehensive above advantage, the present invention has improved the Whole Equipment life-span.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
The accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
