Description

Vertical shaft impact crusher central-axis type iron-stone hybrid chamber

Technical field

This utility model is related to vertical shaft impact crusher, is related to vertical shaft impact crusher center lumen body form, especially It is related to vertical shaft impact crusher central-axis type iron-stone hybrid chamber.

Background technology

Vertical shaft impact crusher is the use of the disintegrating machine with the diverse operation principle of conventional breakers, impingement Rotor is rotated with 1500 revs/min or so of high speed, and rotor edge linear velocity reaches the speed of more than 60m/s, from center pan feeding, is led to Cross by can broken material accelerate to the up to speed of more than 60m/s, strike ferrum wall liner or cliff lining, reach it is broken can broken material Purpose, it is far better to be difficult to improve " vertical hammer break " of speed or " vertical anti-broken " effect than laying particular stress on from side blanking, special Be not centering granule can broken material crushing effect it is preferable.

Vertical shaft impact crusher includes frame, motor, motor rack, upper feed hopper, rotor, middle part, middle part cavity, master Shaft assembly, pulley assembly, bottom etc..Frame is used to bear main screw lift, and by firm ground or some structural buildings are arranged on In；Frame is generally coupled with main frame by playing the vibration isolator of vibration isolation effect.Motor is arranged on motor rack, and motor passes through motor Belt pulley, belt, spindle pulley, impart power to main shaft, and main shaft rotates at a high speed, drives the impact installed in main shaft top Type rotor rotates at a high speed.Main frame bottom is used to bearing spindle assemblies, supporting middle part, accepting can broken material etc..Use at main frame middle part In supporting main frame top, middle part cavity is installed.Middle part cavity be used to accepting rotor dishes out can broken material, there is broken work With.Main frame top is provided with feed hopper, and feed hopper has two kinds of simple bucket and overflow downcomer, can fragment for accept Belt Conveying Material or alternate manner conveying can broken material, simple bucket only accept can broken material, will by the feeding pipe of the bottom centre that struggles against Can broken material be sent to the impact rotor core of at a high speed rotation, there is the tune that can adjust aperture size in overflow downcomer bottom centre Section plate, periphery is provided with transfer window, and when overflow downcomer bottom centre hole size is reduced, supplied materials will be piled up in hopper, reach one After determining height, the strike region of rotor periphery will be entered from peripheral overflow mouth beyond part.Into rotor center can fragment Material, rotor drives can at a high speed dish out after broken material rotation through casting passage from mouth is cast.

The high speed that rotor casts out can broken material, will main strike on the middle part cavity of rotor correspondence circumference range, Generation strike clashes into broken.Bear at a high speed can the cavity wallboard that clashes into of broken material can wear and tear, in order to protect middle part body Housing, cavity wallboard is protected using high-abrasive material, is supported the structure of high-abrasive material or is independently coupled with central enclosure, or One entirety couples again with central enclosure, preferably uses overall structure.High-abrasive material is higher than common material hardness, also there is certain thickness Degree, dishing out in rotor, correspondingly scope surrounds circumference to material, substantially seamlessly bears high-speed material impact, produces fragmentation.

Initial middle part cavity high-abrasive material is to be similar to circular arc, surrounds ring-type.In order to improve crushing effect, and then will High-abrasive material one side makes flat board bulk, claims chopping block, the scope of attack will be born to materials casting direction, so that material is sent out with chopping block Raw positive or near positive shock, this positive or near forward direction is clashed into than other anon-normal to shock, and crushing effect is more preferable.This anvil Plate shape into cavity and fragmentation be referred to as " stone forge iron die cavity ", this die cavity broken material relatively low to medium hardness and abrasion Material effect very well, but to it is more than medium hardness and high abrasion broken material, the loss of high-abrasive material is too fast, high cost, Bad economic results are allowed to, and change frequent, downtime is long；And " stone forges iron " is likely to that excessive stone powder, most of fields can be produced Conjunction causes to waste；Again rotor dish out can the distribution of broken material be not that equivalent is distributed on rotor outlet height, it is but a kind of Normal distribution." stone forge iron die cavity " high-abrasive material weares and teares excessive problem in order to overcome, and industry has " stone-crash-stone die cavity " appearance again, The circulus that section L-shaped is surrounded with steel plate on rotor dishes out the corresponding circumference of material, can broken material fall in L-shaped, press Angle of repose heap sloping ring-type, claims in " stone-crash-stone chamber ", also known as " stone lining chamber ", it is follow-up can broken material will hit here " stone lining " On, the crumbling method of " stone-crash-stone " is formed, this mode overcomes the shortcoming of " stone forges iron " high abrasion, adapts in various hardness And the broken material of high abrasion.But by contrast, crushing efficiency decline is more, and on the one hand " stone lining " is loose or hardened side Formula, there is certain absorption kinetic energy effect, and on the other hand, projectile material and " stone lining " are oblique shocks, is not nearly positive shock.

The height of the anvil in " stone forge iron die cavity ", for having top board, material is entered from rotor center position, from Rotor center leads to edge several materials casting passages, casts channel height by limitation in height between rotor upper and lower bottom plate, thing Material is dished out from this passage, and its corresponding surrounding strike altitude range because casts also oriented no less than this projectile channel height The angle of outer diverging, it is generally higher than casting channel height, so corresponding " stone the forge iron die cavity " anvil of use " enclosed rotor " Height be not less than rotor cast channel height, for without top board " open rotor " for, cast material dispersion angle Bigger, it is higher that its anvil height generally casts channel height than rotor.But, from rotor cast can broken material height point Cloth is not equivalent distribution, but a kind of normal distribution, so the part at anvil height two ends causes to waste using few.If The height of anvil then has partial material to clash into the structure beyond anvil less than rotor channel height, so, there must be other guarantor Protection structure, but also do not have rationally using the structure of anvil.Be more than the height to the anvil in " stone forge iron die cavity " one kind it is accurate Really description, in practice, because the presence of scattering angle material, the height of anvil is similar to rotor height or higher than rotor Highly, later to the description of the anvil height in " stone forge iron die cavity " in, " projectile channel height " or " rotor may be used Highly " two ways, its difference can be disregarded in practice.

In order to improve the crushing effect of both the above die cavity, in CN200520046856.9, in a circumferential direction, some Segmental arc is set to anvil plate, and some segmental arcs are set to stone lining chamber, to change in the change of two kinds of cavity different proportions of circumferencial direction The modulus of fineness and content of stone powder of kind finished product, reduces unnecessary abrasion.But this kind of cavity still has more waste, because casting Can broken material normal distribution, make anvil in the middle of abrasion it is more and be replaced one integral piece anvil, although can carry on the back in anvil Face is designed to closely wait the thickness of abrasion, but still the high-abrasive material for having more costliness is replaced waste.And in this kind of design, stone lining chamber Can only judge in advance with the ratio in anvil chamber, it is impossible at the scene by Operating condition adjustment.This chamber circumferential portion is " stone lining chamber ", part It is " anvil chamber ", can be described as " circumferential hybrid chamber ".In CN201220636591.8, ferrum is installed on the back top in stone lining chamber Chopping block, so the anvil plate of design, actually utilization rate is also relatively low, because its anvil is arranged on the position of middle housing Put, position from rotor more away from, projectile can broken material speed decline it is more, crushing effect decline it is more.Top anvil site Rearward, stone lining height is higher, positioned at cast can broken material normal distribution axis away from side, the fragmentation for rising compared with It is low, and it is away from rotor, Jing after rotor is dished out, because of factors such as windage, gravity, flight speed begins to decline material, and distance is got over Far, speed decline is more, and crushing effect is poorer.By this patent document description and Figure of description, the anvil of this structure is Cyclic form is surrounded, it is important that protection body fuselage, without the nearly positive effect clashed into is formed, thereon reinforcement is also only to increase ferrum The rigidity of chopping block, forms bolt mounting surface and protects the effect of installation bolt, does not also form positive shock.This chamber top is " anvil chamber ", lower section is " stone lining chamber ", be can be described as " upper and lower hybrid chamber "

Also some cavity effects on market, in the portion rearward of stone lining chamber L-type anvil is placed, and its objective is to pacify by anvil Dress with remove, convert between " stone forges iron " and " stone-crash-stone " two kinds of cavitys, so design, its die cavity convert be it is more convenient, But drawback is it is also obvious that the effect of its " stone forges iron " is weakened, because may be all of the occasion of anvil in other designs, this The middle lower section of anvil, by stone lining institute " burying ", is still the effect of " stone-crash-stone " in chamber, and the utilization of its anvil is insufficient, substantially under Half portion is not worn and torn, and top also weares and teares less, once anvil middle part is worn and torn, one integral piece anvil is just abandoned, and is wasted very big.This kind of chamber It is stone lining in front of rotor, is " anvil " away from the rear of rotor, can be described as " hybrid chamber in front and back ".

The content of the invention

The utility model discloses vertical shaft impact crusher central-axis type iron-stone hybrid chamber.Break to improve vertical shaft impact The crushing efficiency of broken machine, improvement can broken material fineness mould degree, reduce content of stone powder, reduce the steel abrasion loss of finished product per ton, and Improve the adjustment motility at scene, can be in high abrasion can be in broken material, tradition can only use the occasion of " stone-crash-stone die cavity ", Increase as far as possible few high-abrasive material abrasion, improve the using effect of hereinbefore several " hybrid chambers ", reach close to " stone forges iron type The crushing effect in chamber ", can make whole crushing production line, play whole abilities of other machinery equipments, improve final products yield, Improve the output proportioning of each final products, be allowed to more reasonable.And it is high to provide scene adjustment height, front and back position, and follow-up adjustment Degree, thickness, the motility of front and back position, and can be according to Different field, different operating mode flexible transformation between various die cavities.

The technical solution of the utility model is, the high efficiency of " stone forge iron die cavity ", improves in former " stone lining chamber " in order to utilize Crushing effect, according to cast can broken material normal distribution, this hybrid chamber anvil casts passage for the former rotor that is usually less than About 20%～70% height of " stone forge iron die cavity " anvil of height, i.e.,：This hybrid chamber anvil is that rotor casts channel height 20%～70% height, this anvil height center line and projectile can the normal distribution axis of broken material essentially coincide, in rotor Still L-shaped ring-type surrounded with steel plate on the corresponding circumference of material of dishing out, anvil is in this L-shaped is surrounded.Because of anvil height center line and throwing Penetrate can overlapping of axles in broken material normal distribution, can be described as " central-axis type iron-stone hybrid chamber ".But the spirit of its great lumen type conversion Activity, while also possessing the functional effect of " circumferential hybrid chamber ".

The height of this anvil can cast in the height of channel height 20%～70% in rotor and change.20%～70% anvil Highly determine that principle is that anvil is shorter, then high-abrasive material utilization rate is higher, and anvil is longer, then crushing efficiency is closer to " stone is beaten Ferrum " efficiency.And above and below this chamber anvil, still form stone lining, this scope projectile can broken material, be still that " stone is beaten Stone " effect, by cast can broken material normal distribution curve, it is less away from the ratio of axis, although being herein " stone-crash-stone " Effect, but major part can broken material be fall cast can broken material normal distribution curve near axis, so, crush effect Really close " stone forges iron " effect, but the utilization rate of anvil improves a lot.The determination of final anvil height, can sentence in advance It is disconnected, determine when manufacturing, it is also possible to which scene is made the effect of differing heights and compared, and finally determines optimum height, and in follow-up anvil There is provided by this height in component.User can obtain optimal in anvil utilization rate, abrasion cost, between percentage of damage, modulus of fineness Cost performance.

Now, except the effect that stone forges iron, also a kind of efficient crumbling method, " stone forges iron " resilience can broken material Forming part " stone-crash-stone head-on collision " effect, this " stone-crash-stone head-on collision " be not can broken material and fixed stone lining shock, Be not cast can broken material and the freely falling body without horizontal velocity from top overflow drops down can broken material bump against, but have The resilience material of certain speed and the shock for casting material, this shock, effect more preferably, and is not lost high-abrasive material, and more is occur At " stone forge iron chamber ", and it is to dish out and just can relatively mostly occur and this clash into broken near the axis of broken material normal distribution. Near axis can broken material clash into anvil after, substantially rebound vertically, its resilience route with projectile route it is Chong Die, Jiu Huifa Raw " stone-crash-stone head-on collision " effect, and herein, can broken material cast very big with the density of resilience, the probability of shock is very big. Away from the position of normal distribution axis, can broken material be bevel and anvil clashes into, can after broken material and anvil shock, into Symmetry angle is reflected away, and is not overlapped with material route is cast, and seldom has an opportunity to clash into, and its density is less, hits The probability for hitting is also less.If material abrasivity is stronger, anvil height can be reduced, while making anvil unit area bear more Many can broken material shock.Closer to cast can broken material normal distribution curve axis, " stone-crash-stone head-on collision " effect gets over By force, although material abrasivity improves more by force steel consumption, herein, the utilization rate of unit area is very high, the broken finished product effect of raising Benefit will consume more than steel.

The circulus for still section L-shaped being surrounded with steel plate on rotor dishes out the corresponding circumference of material, the close rotor of L-shaped Generally there be a circle seam circle inner side, protects base plate, stone lining is firmly shaped, and is difficult to be blown by the high wind that the rotor of intracavity is formed Dissipate.Can broken material fall in L-shaped, by angle of repose heap sloping ring-type, anvil in this L-shaped is surrounded, the space below anvil Still form stone lining, the stone lining below anvil close to vertical angle, in the stone lining that previously described " stone-crash-stone die cavity " is formed, Be by the angle of repose of material formed can broken material entity lining, angle of repose is generally between 30 degree to 40 degree, and indivedual materials are viscous Property is stronger, can form the angle of repose more than 40 degree, and this operating mode is less.And can broken material cast direction be mostly level side To, this projectile can positive impact effects of the oblique shock than 90 degree be poor between broken material and stone lining, and there is no resilience material " stone-crash-stone head-on collision " effect, now, the spatial altitude below anvil is shorter, and stone lining is easy to be piled into and connects in narrow space 90 degree of vertical cliff lining is bordering on, so as to reach close to positive impact effects, and also has " stone-crash-stone head-on collision " effect of resilience material Really, this belongs to subsidiary increase crushing effect.

Pattern as formed " central-axis type iron-stone hybrid chamber "+" circumferential mixing die cavity " using part anvil is removed, Because circumferential width shared by an anvil is narrower, stone lining is also easy to pile up, the angle of repose of the stone lining stocking angle of formation than free state Big, stone lining is more firm, is less susceptible to be broken up, and is dispelled by whirlwind, and the crushing effect of shock is more preferable.

Stone lining above anvil, original " stone-crash-stone " stone lining, close cavity ring and superposed stone lining, thinner thickness, Pile up firmness it is limited, high-speed projectile can broken material strike under, often broken up, dispelled by whirlwind, in a kind of loose heap Long-pending state, it is easy to absorption clear up cast can broken material kinetic energy, so as to reduce fragmentation.Now the position of anvil projects Outside former stone lining angle of repose entity, interlayer is formed equivalent in the middle and upper part of die cavity, increase the die cavity annular of top stone lining Width, the stone lining of accumulation is still piled up by angle of repose, but because width increase is many, the thickness of stone lining also increases a lot, the jail of stone lining Soundness increases a lot, this stone lining closer to rotor, cast can broken material speed decline it is less, so as to improve broken effect Really.Although with the abrasion of anvil, this stone lining can also reduce thickness, and also the stone lining very thinner than originally is more firm, and crushing effect is more It is good.

The motility of anvil height and position adjustment, i.e. anvil height and position is adjustable, in principle in the height of anvil Line should with cast can broken material normal distribution curve dead in line.Cast can broken material normal distribution curve axis lead to Often overlap with the height center line of rotor, but may also have difference, different by rotor size, structure, depth, feeding coal is different, in Heart sub-material cap shaped difference etc. affects, rotor height center line with can the normal distribution curve axis of broken material usually occur necessarily The skew of amount.Different field working conditions are different, during design height center line with it is actually used when normal distribution axis simultaneously Not necessarily it is consistent, therefore, the height of anvil should be adjusted according to Different field, except design rank that can be before the manufacturing Section is judged, is adjusted accordingly outward, also can adjust at the scene, and after initial use, it is single that using effect feeds back to manufacture Position, can subsequently provide the anvil component after adjustment, even if changing different using scene, still can neatly adjust.User can With in anvil utilization rate, abrasion cost, optimal cost performance is obtained between percentage of damage, modulus of fineness.

Anvil is also the factor for affecting crushing effect with a distance from rotor, can be installed in former anvil site, it is also possible to move back Afterwards position is installed, and is essentially anvil is exposed to outside the stone lining of lower section, i.e., outside the entity area that the angle of repose of stone lining is formed, And this stone lining matches somebody with somebody difference because various material varieties are different, moisture content is different, viscosity is different, constitute level, the angle of formation is also different, Therefore be difficult to determine anvil site in advance, herein, by the way of flexible adjustable position, the position of anvil is allow by scene Requirement adjust.If material abrasivity is not too strong, then anvil can be made near rotor, make the material speed that rotor is dished out because of wind The factors such as resistance, gravity decline less, so as to improve percentage of damage, improve anvil utilization rate, close " stone forges iron " crushing effect, if Material abrasivity is stronger, then can step back installation, makes abrasion decrease.

This is the motility of anvil front and back position adjustment, i.e. the front and back position of anvil can be adjusted on demand, not be It is changeless.Front and back position referred to, refers to distance of the anvil from rotor outer circle, and the front and back position of anvil can be according to not Scene adjustment together, except design phase that can be before the manufacturing is judged, is adjusted accordingly outward, uses for the first time Afterwards, using effect feeds back to manufacturer, and the anvil component after adjustment can be provided again, even if changing different use scenes, Still can neatly adjust.User equally can obtain most in anvil utilization rate, abrasion cost, between percentage of damage, modulus of fineness Good cost performance.

Anvil bears the scope of attack, in principle should in the face of projectile can broken material supplied materials direction, projectile can broken material supplied materials Direction, maximum influence factor is the linear velocity of rotor edge, is described exactly, is at rotor thrower head carbide blade Linear velocity, be herein can broken material leave the rearmost point of rotor, two be can the speed that outwards slides from rotor center of broken material Degree, this constraints are complicated, it is difficult to quantitative Analysis, three be can broken material leave after rotor by gravity, windage, and other can break Broken material affects.Comprehensive each influence factor, with rotor edge linear velocity as maximum effect factor, can design anvil angle with this, Further according to onsite application state, make corresponding amendment.

The integral form of anvil can be diversified, and the pattern sold on all public publications or market can be applied to In this structure, the height of its mid portion about 20%～70% is simply taken.Normally, anvil is to be fixedly installed to main frame middle part shell On internal or special anvil support, supporting structure is preferably used, this support constitutes a circumference substantially, overall can be hung Dress, dismounting.

The installation of anvil component, dismounting are very convenient, and the installation of anvil is in addition to the existing mode of upper segment description, in order that holding high Anvil utilization rate made by expensive high-abrasive material is as far as possible high, as far as possible few setting mounting structure, so, often using modes such as clamps Install, this kind of mounting means, the use environment of main frame is very severe, and inside cavity piles up silt particle, also certain water content, Often that anvil draw-in groove etc. is stuck, rust is dead, removes clamp difficult, and traditional anvil abrasion is unequal, and the abrasion of anvil middle part is close to It is accomplished by changing during capsule components, still there is more preservation top and the bottom, on the one hand wastes larger, on the other hand also results in dismounting tired It is difficult.The mode of overall anvil frame, uses when being often used in replacing lumen type, is individually replaced anvil, does not generally dismount anvil frame, It is also to remove anvil from anvil frame.In order to overcome this difficult, it is also convenient for adjusting height, height and position, the anteroposterior position of anvil Put, by anvil and backboard, base plate composition anvil component.This component hangs tag again on cavity backboard, anvil component integral hoisting, Remove very convenient.The more traditional anvil of this anvil is short, and abrasion is abundant, and mid portion has ground, and still has backboard, base plate to adhere to wear-resistant one The section time, now anvil remainder may be ground, intactly using whole high-abrasive materials, and backboard, the bottom of anvil component Plate is that common iron makes, and cost is relatively low, and last remainder is allocated as abandoning process, little waste.

This anvil component with backboard, base plate, the mounting structure of its die cavity rearward, even if anvil has all worn and torn, is carried on the back Plate base plate has part wears, without abrasion die cavity mounting structure part because the stone lining of bottom by with the abrasion of anvil by Step extends, and within the angle of repose entity of stone lining, the backboard of anvil will not all be worn and torn the mounting structure of die cavity, the peace of die cavity Assembling structure more will not be worn down to.

Design of the anvil with backboard, the setting height(from bottom) for alloing anvil is adjusted, if the thickness of the base plate that adds deduct or Steel plate combination number of packages, it is possible to improve or reduce the height of anvil, makes anvil height center line and dish out can broken material normal state point Cloth axis overlaps, and makes high-abrasive material use maximization.

The front and back position of anvil can be adjusted, as long as increasing or decreasing the thickness of anvil backboard, you can before and after making anvil Position changes, so as to adapt to different requirements.

The thickness of anvil can adjust, and anvil back plate design has larger thickness, can as requested switch to anvil thickness, to having Scene, the abrasion of anvil is very fast, and replacing needs to shut down, artificial operation, in follow-up accessory, reduces back plate thickness, increases Anvil thickness, can extend anvil use time, reduce downtime.

The shape of anvil can be changed, Different field, and the last nubbin retained of anvil abrasion is different, follow-up Can correct in accessory, make anvil whole as far as possible be close to synchronous abrasion and complete.

The follow-up improvement of anvil can be suitable for, because anvil is provided with backboard as an entirety, the shape of anvil, clamp Structure changes, and simply changes the version of backboard, constant with the mounting structure of die cavity, subsequently has more excellent anvil to set Meter, is equally applicable to the main frame produced before this.

The global design of lumen type, die cavity can be fixed in main frame middle housing, non-exchange, and more preferable scheme is, such as Global design is adopted with tradition " stone forge iron chamber " and " stone-crash-stone chamber ", can be the same with integral replacing, central-axis type iron-stone hybrid chamber Using global design, in most short time, minimum replacement cost, freely change between three kinds of lumen type in the short time.

The great flexibility that lumen type inside is changed, although central-axis type iron-stone mixing chamber initial purpose is to improve stronger abrasion Property can broken material percentage of damage, determine that anvil highly takes the height of " stone forges iron " anvil 20%～70%, but scene can fragment Material qualitative change may be larger, and main frame may change using scene, and being described above certainly can be changed by changing die cavity Become lumen type, but central-axis type iron-stone hybrid chamber itself just possesses the motility of conversion lumen type.As anvil highly takes and former " stone forges iron " The same height of anvil, and take anvil site near rotor, then " stone forges iron " chamber is converted to, certainly, with original-pack " stone forges iron " Still there is some difference in chamber, herein, it is impossible to use " middle part air -return duct " patent.

Anvil component is removed into part, then has the effect similar to CN200520046856.9, but also have larger difference. In a circumferential direction, some segmental arcs are iron-stone hybrid chamber to central-axis type iron-stone hybrid chamber, and it is stone lining chamber that some segmental arcs are returned, to justify The change of two kinds of cavity different proportions of circumferential direction reduces unnecessary abrasion improving the modulus of fineness and content of stone powder of finished product, The adjustment of this ratio, with variation, completes at the scene completely.And CN200520046856.9 can only be designed before making The ratio in two kinds of chambers, it is impossible to convert at the scene.The anvil component that central-axis type iron-stone hybrid chamber is pulled down still is usable in follow-up operation In.Adjustment motility is high, can will appoint easy one or several anvil components dismountings, arbitrarily combines, the formation stone of one ferrum one, one The stone of ferrum two, the ferrum of two stone one, the ferrum of two stone two, etc..This kind of " central-axis type+circumference mixing die cavity " not as CN200520046856.9 that Sample high-abrasive material still has larger waste, by anvil height, the adjustment of position, the herein waste without high-abrasive material.Reach and change The modulus of fineness and content of stone powder of kind finished product, reduces the purpose of unnecessary abrasion, there is very big motility, and it is very careful to carry out Adjustment.

Some operating modes, it is not necessary to anvil, such as main frame, can broken material finished product job requirements in certain building site operation a period of time Change, or move to other building sites operation etc., operation purpose be changed to pair can broken material shaping, crush and require, only reduce It can broken material elongated particles, or it is broken require less, stone-crash-stone can be competent at completely, or material source is changed to high abrasion Material, anvil rapid wear, etc..At this point it is possible to anvil component is all removed, return " stone-crash-stone die cavity ", use completely Stone lining is broken, shaping, the wear problem without anvil.Even if not changing, operation a period of time is treated, anvil all weares and teares, no New anvil being changed again, being then converted to stone-crash-stone die cavity naturally, scene can freely decide whether to shut down removes anvil component.

Return to " central-axis type iron-stone hybrid chamber " from " stone-crash-stone die cavity " is changing into, it is only necessary to install anvil component, Install anvil component number of packages number, can be tested at the scene, carry out careful adjustment.Can be with follow-up anvil group During part accessory is ordered goods, propose that more suitably height, position, shape etc. are required.

This kind of die cavity requires that the radial width of central cavity presses the annulus width design of the die cavity of stone-crash-stone, there is enough rings Bandwidth, because of the angle of repose entity of stone lining, ring width is wider, and the stone lining height of outermost is higher, when the height of the stone lining of outermost reaches To or during close rotor height, now, because cast can broken material normal distribution, it is little can broken material reach on rotor The highly corresponding stone lining position of backplate, the exposure of cavity structure more than this position, will seldom have projectile can broken material beat Hit, have very least a portion of reflection can broken material may reach this position, but factor amount is few and granularity is little, stall after shock Again through gravity, windage reduction of speed, essentially without the steel construction herein that weares and teares.

If, the annulus narrower width of die cavity, the angle of repose entity part of stone lining, the height for finally reaching is not enough, does not have Protect the steel construction of die cavity, cast can broken material it is more can broken material reach the steel construction of die cavity, if do not had Extra protection, the top of the steel construction of die cavity will be worn, as described by CN201220636591.8, its die cavity it is upper Portion is easier to be worn, and needs extra protection.

Although central-axis type iron-stone hybrid chamber initial purpose be improve stronger abrasion can broken material percentage of damage, for In the material of medium and following abrasion, this central-axis type iron-stone hybrid chamber can be equally used, i.e.,：" stone forge iron chamber " is used in tradition Operating mode, use " central-axis type iron-stone hybrid chamber " can be replaced by, because dishing out the crushing of normal distribution axis away from material Material is little, and this is changed to the percentage of damage of stone-crash-stone away from part from the percentage of damage that stone forges iron, for overall percentage of damage shadow Sound is less, and 70%～30% anvil abrasion can be saved on cost.And, many low corrosion materials forge iron with stone Chamber, reduction ratio is very high, but the yield of stone powder but also far beyond demand, cause very big waste, be partly changed to stone-crash-stone effect, stone Powder content has declined, and also reduces waste, reduces cost.

Can broken material for stronger abrasion, although can the abrasion of broken material improve, central-axis type iron-stone hybrid chamber Anvil abrasion cost is improve, because the utilization rate of anvil is improved, the part of waste, overall unit product steel per ton is eliminated Abrasion loss is not improved, though or increase, percentage of damage improves more, and overall efficiency is improved, and makes the energy of whole system Power is preferably played, and benefit is higher.And, this kind of die cavity has a diversified adjustment modes, user can anvil utilization rate, Abrasion cost, optimum efficiency is obtained between percentage of damage, modulus of fineness.

Middle department's anvil loss of weight, in the main frame on market, part middle part is not opened the door, and this main frame uses central-axis type iron-stone Hybrid chamber is complete 360 degree circumference to.And have part main frame being opened the door at middle part, convenient observation, detection, maintenance, replacing is matched somebody with somebody Part etc., this kind of main frame is to interrupt on the corresponding radian of middle department, and traditionally, the forge iron anvil of middle sector location in chamber of stone is Hang in department, because of arm length, weight weight, mobile, rotation is more difficult, it is also possible to cause deformation of door-plate etc., this axis The theory of formula iron-stone hybrid chamber, the anvil in Shi Zhong departments is reduced to 30% or so of original weight, make this problem have compared with Good settling mode.Also a kind of pattern, is that anvil is placed on the base plate of middle part, is removed behind the door, then remove anvil, originally because Anvil weight weight, volume are big, remove mainly manually, and narrow space, operation is very inconvenient, similarly, after reducing weight, in The loss of weight anvil movement of department will become not difficult thing.

The mounting means of anvil, because the front and back position of anvil changes larger, when anvil is located at rearward position, is hanging down Nogata is interfered upwards with the annular upper cover plate above L-shaped, if be first put near the position of rotor, then manually with artificial mode Mobile, this mode is feasible, but anvil component is heavier, and movement is more difficult, so that cover plate is made into the mode of being actively coupled, and can be divided into Several piece.When mounted, anvil component is first installed, hybrid chamber annular upper cover plate is installed afterwards, during dismounting, first tear annular upper cover plate open, after Tear anvil component open.

The beneficial effects of the utility model are：First, central-axis type ferrum can be replaced by using the operating mode in stone-crash-stone chamber in tradition Stone hybrid chamber, improves crushing efficiency, improvement can broken material fineness mould degree, reduce the steel abrasion loss of finished product per ton, and improve The adjustment motility at scene, reaches the crushing effect close to " stone forge iron die cavity ", and two, whole crushing production line can be made, play Whole abilities of other machinery equipments, improve final products yield, improve the output proportioning of each final products, are allowed to more reasonable. 3rd, the operating mode in traditional chamber of being forged iron using stone, is also replaced by central-axis type iron-stone hybrid chamber, with close crushing efficiency, reduces every Ton finished steel abrasion loss, reduces content of stone powder, and improvement can broken material fineness mould degree.The 4th, live adjustment position height is provided, it is front The motility of position afterwards, and follow-up adjustment anvil height, anvil site height, thickness, shape, the motility of front and back position, five, Can be according to Different field, different operating mode flexible transformation between various die cavities.6th, middle department's anvil weight saving, easy to operate.
