Description
Technical field
The present invention relates to disintegrating machine technical field, is more specifically the equal type fine disintegrating machine of a kind of jaw formula.
Background technology
Jaw crusher, also claims jaw broken, is with the longest history, one of most popular disintegrating apparatus.
Jaw is broken is typical " slightly broken " equipment.
Thick broken two connotations that have here:
One, the broken not precision equipment of jaw, (machine tool just can be competent at) simple in structure, easy to manufacture, use and keep in repair all and facilitate, operating cost is also very low, and (wearing and tearing that for example jaw is broken are the broken 1/3-1/5 of counterattack, power consumption is the 1/3-1/2 of impact cutting), so jaw is broken always welcome so far;
Two, the discharging that jaw is broken is thicker, is difficult to broken fines, and this breaking cavity structure broken with jaw is relevant, is conventionally crushed to the following particle of 30mm and has just been difficult to.
If can be with the broken broken fines of equipment of jaw, use the equipment of " thick broken level " to do the work of " level in small, broken bits ", its economic benefit can significantly promote.
The even function in small, broken bits of the broken shortage of prior art jaw, its limitation is:
The one, the straight plate structure of jaw is unreasonable.What form crusher chamber is two jaws, and the straight plate structure of prior art jaw has determined the chamber type that crusher chamber is V-shaped, it after each circulation stroke work done, discharge be the material of a pile triangle volume.Because jaw crusher is typical individual particle broken (there is no lamination fragmentation), so the material particles that triangle volume holds size is just by triangular shaped distribution, up big and down small, concentration degree is poor, it is high that the on-the-sieve material (material that surpass up to specification size) of discharging after screening returned to heavily broken ratio, affects crushing efficiency;
The 2nd, the tooth-shape structure irrational distribution of jaw.Material is along with its particle size of broken process progressively diminishes from top to bottom, according to reason, the tooth-shape structure of jaw also should correspondingly diminish from top to bottom gradually, to give full play to the function of tooth-shape structure " split brokenly, roll over and break, rack ", large granular materials is broken with large tooth-shape structure, and small particles material is broken with little tooth-shape structure.But the profile of tooth of prior art jaw is unalterable, restricted giving full play to of crushing function.
The 3rd, Cracking Mechanism is unreasonable.Prior art jaw crusher is single Cracking Mechanism, the particle size of discharging finished product and crusher chamber gap size are directly equivalent to, be that great crusher chamber gap just goes out great product, and the gap of crusher chamber is subject to the structural limitations can not be too little, thereby has restricted function in small, broken bits.
Therefore, wish is directly broken fines with jaw crusher, should break through from the innovative design of jaw and the lifting of Cracking Mechanism.
Summary of the invention
The invention provides a kind of simple in structure, cheap, equal type fine disintegrating machine of jaw formula of economizing power consumption rate, having broken prior art, to use hammer, roll-type and impact type type to need as the feed particles of equal type fine disintegrating machine little, must multiple stage crushing realizes the limitation of sand processed.
The present invention is achieved by the following scheme: the equal type fine disintegrating machine of a kind of jaw formula, comprise frame, eccentric drive axis mechanism ,Dong jaw mechanism, bracket mechanism and a pair of jaw, described jaw comprises main body jaw, on the working face of main body jaw, is provided with tooth-shape structure, it is characterized in that:
Described main body jaw both ends are at least extended and are provided with accessory body jaw on one end; On the working face of accessory body jaw, be also provided with tooth-shape structure;
Tooth-shape structure on described accessory body jaw working face is less than or equal to the tooth-shape structure on main body jaw working face, and the tooth depth of accessory body jaw working face, the facewidth and space width are all less than or equal to tooth depth, the facewidth and the space width on main body jaw working face; The length of described accessory body jaw is 110～550mm;
The angle angular range that described main body jaw and accessory body jaw form is at 0-15 degree.
Intention of the present invention is: jaw is promoted to the composite structural design that main body jaw and accessory body jaw combine by the monomer structure design of prior art lower straight-plate shape, broken efficiency is pursued in the design of main body jaw plate structure, and broken uniformity is pursued in the design of accessory body jaw plate structure.
Two macrostructure features of the present invention are: 1. the composite construction that main body jaw and accessory body jaw combine (form crushing pair chamber by fixed and movable two accessory body jaws, crushing pair chamber is long and narrow die cavity type); 2. the tooth-shape structure on accessory body jaw working face is equal to or less than the tooth-shape structure on main body jaw working face, and the tooth depth of accessory body jaw working face, the facewidth and space width are equal to or less than tooth depth, the facewidth, the space width on main body jaw working face.
Core technology of the present invention: the composite structural design combining with main body jaw and accessory body jaw substitutes the monomer structure design (consisting of " sleeve configuration structure crusher chamber ") of the straight plate shape of prior art, and the combination of using crusher reason, making is the function that the jaw crusher of coarse smash equipment has even fine crushing material originally.
The design of " accessory body jaw " is one of technological highlights of the present invention.Because " sleeve configuration crusher chamber " (the secondary crusher chamber) being comprised of two " accessory body jaws ", is the critical structures design that realizes even function in small, broken bits.(it possesses " structural element " and " profile of tooth key element ")
One, " structural element " (the sleeve configuration crusher chamber type being formed by accessory body jaw):
Eccentric shaft turns around, a broken circulation, and the material discharging is the volume in the Yi Ge del district of crusher chamber bottom.First analyzing extreme case, under the type state of inverted triangle chamber, is that the gap of crushing pair two jaw lower ends is adjusted to zero (surpass zero will cause jaw to bump against and ruin machine) even floss hole is adjusted to minimum, still can give off coarse fodder.
And under sleeve configuration structural capacity, can floss hole size be set according to required material finished size size completely.But the volume that guarantees each discharge is all the material in this sleeve configuration structural area, does not allow epicoele material omit in printing.During design, should calculate the length in sleeve configuration structure chamber, under discharge volume the same terms, discharge material is thinner, and sleeve configuration structure cavity length is longer, otherwise shorter.
Obviously, bottom is provided with the crusher chamber of sleeve configuration structure, thinner and more even than prior art " V " character form structure chamber type fragmentation finished product material out, the superiority in Here it is sleeve configuration structure chamber.
The designing requirement of sleeve configuration structure crusher chamber:
1, the volume of sleeve configuration crusher chamber should be greater than the volume of each broken circulation institute discharges material; And the material in this volume is controlled in narrow alveolus scope, particle is controlled at trimmed size material size range;
2, the length of sleeve configuration crusher chamber should meet the required height of each broken recycle stock freely falling body, can not allow material in main crusher chamber alter to slip and under;
3, the angle of the secondary crusher chamber of sleeve configuration can be selected between-8～+ 8 degree, has following three kinds of states desirable:
(1). negative angle is conducive to discharges material, but can not be excessive, and excessive material is difficult for compacting;
(2). positive-angle is conducive to broken fines, but also unsuitable excessive, is excessively unfavorable for even fragmentation;
(3). it is broken evenly that zero degree is conducive to material, but because sewing jaw is to take the fan shape moving that eccentric shaft is the center of circle, and jaw is among continuous wearing and tearing change, therefore zero degree be only theory analysis point and moment transient state, Practical significance is little.
The angle of crusher chamber is a dynamic concept, and we will study and assurance is an angular range, and the applicant is set between-8～+ 8 degree.
Two, " profile of tooth key element " (tooth-shape structure on main body jaw and accessory body jaw is not of uniform size):
For adapting to material, from upper end, the main chamber of fragmentation, be fed to the situation that the process of crushing pair chamber lower end discharging, particle diminishes gradually, again crusher chamber is designed to profile of tooth difference structure, be that tooth-shape structure size diminishes from top to bottom, large granular materials is broken under large tooth-shape structure, small particles material is broken under little tooth-shape structure, reaches the highest crushing efficiency.
" crusher reason " used is another technological highlights of the present invention.
The function even in small, broken bits of above-mentioned sleeve configuration breaking chamber structure be have circumscribed very greatly.When raw meal particle size reaches the rank of sand and powder, under single Cracking Mechanism, crusher chamber width is adjusted to sand and powder, and (0.15mm is hereinafter referred to as powder, 04.75～0.15mm particle is called sand) like this gap of fine dimension be unpractical because be that the accuracy of manufacture, installation accuracy or the performance accuracy of jaw is all far can not meet, say again, even if so thin Micro-chamber gap can be realized, its output is also atomic, does not have Practical significance.So the present invention is designing on the basis of sleeve configuration crusher chamber, use further crusher reason, to reach evenly object in small, broken bits.
Lamination fragmentation is for single fragmentation, single fragmentation be between two jaws only single material in fragmentation, be jaw pressing materials; Lamination fragmentation is between two jaws, to have many materials in fragmentation, is material pressing materials.
Lamination fragmentation is to form under the motion feature condition of sewing jaw " large slack list, the large bed of material, large stroke, large pilled-in selvedge ".(stroke refers to the move distance of sewing jaw bottom when doing broken work done, claims again stroke; Stroke finishes two jaw bottoms and when minimum range, claims pilled-in selvedge, stroke to start also i.e. two jaw bottoms when ultimate range, to claim slack list, and the difference of the size of slack list and pilled-in selvedge is also stroke).
" large slack list " motion feature can make crusher chamber fall into enough materials, forms material bed (the large bed of material) of adequate thickness;
It is broken that " large stroke " motion feature makes material produce enough laminations;
It is evenly in small, broken bits that " large pilled-in selvedge " motion feature can be realized crusher chamber under the state of non-fine clearance chamber type;
Even mechanism in small, broken bits of the present invention is achieved in that
1, first at main body jaw (movable and fix two main body jaws), be provided with bottom accessory body jaw and form " the even broken chamber of long and narrow formula ", the raw meal particle size that each operation cycle of crusher chamber is emitted is controlled within the scope of required size, realizes evenly in small, broken bits;
2, for adapting to material, from crusher chamber upper end, be fed to the situation that the process of crusher chamber lower end discharging, particle diminishes gradually, again crusher chamber is designed to profile of tooth hierarchic structure, be that tooth-shape structure size diminishes gradually by level from top to bottom, make large granular materials broken under large tooth-shape structure, small particles material is broken under little tooth-shape structure, reaches the highest crushing efficiency;
3, there is scientific and reasonable crusher chamber, more supportingly have a scientific and reasonable Cracking Mechanism, just can give play to the ultimate attainment of powder process function:
Jaw crusher is typical single Cracking Mechanism, and when broken coarse fodder, the pilled-in selvedge size of epicoele is exactly the particle size of material substantially.The independent thinking with " single Cracking Mechanism " realizes ultrafine grinding (powder process) and does not obviously gear to actual circumstances, because chamber type pilled-in selvedge size is adjusted to the words of powder particle sizes, so: 1, the accuracy of manufacture of chamber type and installation accuracy are difficult to reach, 2, under so thin Micro-chamber, output is also very little, without practicality.
The fragmentation campaign of " large pilled-in selvedge, large stroke " can realize " crusher reason ", and the broken fragmentation of so-called lamination is exactly under the high pressure producing at " large stroke ", has multilayer particle material between the type of chamber, and the mode of squeezing material by material realizes in small, broken bits.Like this, chamber type pilled-in selvedge size particle size not necessarily.That is to say, under " crusher reason ", larger pilled-in selvedge can be broken excess of export fines (such as the chamber type pilled-in selvedge size of 10～20mm, just can be broken going out the powder below 0.15mm).
The origin cause of formation that forms chamber type high pressure fragmentation be " large stroke ", under large stroke, inlet amount is large, the high pressure producing under the high ratio of reduction when large pilled-in selvedge is broken, shows as lamination crushing function.Under single Cracking Mechanism, " pilled-in selvedge " determines granular size, and " slack list " determines output; Under crusher reason, " large pilled-in selvedge, large stroke " not only determined ultra-fine particle, but also determined higher output.
Generally speaking, the broken type of jaw will be realized equal fine crushing function, and large " key element " is integrated forms by three: " flute profile+type+mechanism ".
1. " the sleeve configuration structure " brought by profile of tooth innovative design, the innovation of " stepped construction " crusher chamber are bases;
2. " dual-crank-rocker mechanism disintegrating machine " and " compound crank and rocker mechanism disintegrating machine " is necessary and sufficient condition;
3. " crusher reason " is core.
Remarkable functional character of the present invention is: make jaw crusher type realize even broken fines.It has two large features: being 1. " carefully ", is 2. " evenly ".
So-called " carefully " is exactly the prior art jaw crusher with respect to same specifications and models, and the material that institute's fragmentation goes out is much thin;
So-called " evenly ", the material that fragmentation goes out exactly, its granular size can concentrate in the specification limit of required finished product material to greatest extent, and product particle size concentration degree is very high.
Except above-mentioned remarkable functional character, the beneficial effect simultaneously bringing also has:
1. improve output.As the plane of disruption of jaw plate structure of the present invention being designed to shaped negative angle structures (referring to two plane of disruption angles), in broken motion process, its jaw has a quick propulsive force (if eccentric shaft turn to be set to consistent with logistics direction) to material.This will increase substantially jaw bankruptcy amount.
Because the broken speed that prior art jaw is broken is natural free-fall velocity, is a limiting value.The present invention has broken through this limiting value.
2. improve the ratio of reduction.As the plane of disruption of jaw plate structure of the present invention being designed to the segmentation structure of bypassing the immediate leadership, can increase substantially so the ratio of reduction of disintegrating machine.Improved the crushing performance of disintegrating machine.
3. reduce abrasion.In the present invention, have crusher reason, have the material of considerable part to be " material dnockout ", therefore abrasion greatly reduce.
Prior art jaw crusher is owing to limit by jaw plate structure feature, typical " slightly broken " equipment, allow " slightly broken " equipment realize even broken fines, be not only the significantly lifting of jaw crusher function, especially field of cracking machine great technological revolution!
XOR is replaced such scheme by following scheme, the equal type fine disintegrating machine of formula, comprises frame, eccentric drive axis mechanism ,Dong jaw mechanism, bracket mechanism and a pair of jaw, and described jaw comprises main body jaw, on the working face of main body jaw, be provided with tooth-shape structure, it is characterized in that:
Described main body jaw both ends are at least extended and are provided with accessory body jaw on one end; On the working face of accessory body jaw, be also provided with tooth-shape structure;
Described accessory body jaw working face is planar light plate structure; The length of described accessory body jaw is 110～550mm;
The angle angular range that described main body jaw and accessory body jaw form is at 0-15 degree.
The design principle of planar light plate structure: when particle is the rank of sand, powder, tooth-shape structure has lost broken meaning, available flat board, for it, is that by the superiority of slab construction discharges material is more abundant, because do not have tooth pitch to take type space, chamber.
Planar light plate structure is exactly tooth depth, the facewidth and the space width limiting condition while being zero, and it is structure that fall behind, superseded with respect to tooth-shape structure, but presents great advantage here.Because in the afterbody chamber of multistage ladder crusher chamber, its broken object has been tiny material, broken task be fines homogenous superfine is broken again, from " breaking ", be promoted as " mill ", mill is ultrafine grinding (sand processed, powder process) better.
In sleeve configuration structure chamber, planar light plate structure jaw has following superiority:
1. for fines rank, no longer need " split broken, roll over broken, squeeze broken " etc. need tooth-shape structure to complete effect, so tooth-shape structure is ineffective, the shortcoming of planar light plate structure has not existed;
2. broken fines is very sensitive to chamber type precision, and planar structure is higher than the contact-making surface precision of tooth-shape structure;
3. tooth-shape structure and the plane light plate structure of same stroke, the former differs at granular size, and the latter's interlocking pattern is better, and fine granules is more even.
One section of planar light plate structure is designed in lower end (in sleeve configuration structure chamber) in crusher chamber, is the another technological highlights in the present invention.
As preferably, the only bottom of described main body jaw is extended and is provided with accessory body jaw.
It is long and narrow die cavity that such major-minor body jaw forms lower end after being combined into crushing pair.Make material evenly in small, broken bits, discharging particle size concentration degree is high, circulation broken material is steam again in minimizing, saves power consumption.And realize " granule, large output ".
As preferably, the upper/lower terminal portion of described main body jaw all extends and is provided with accessory body jaw.
The upper and lower two ends of main body jaw arrange accessory body jaw two large functions: the one, and having increased shakes presses the function of cavity configuration; The 2nd, realize upper and lower symmetrical function of exchanging:
Jaw is designed to the function of " symmetrical exchange ".
The present invention is designed to two ends simultaneously to a turn back angle extend a section of a side by sewing jaw, and the angle of turning back equals the angle [alpha] (α is for being less than or equal to 26 degree) of former crushing pair, and every edge lengths is 1/4～1/6 of former crushing pair.Also can fixed jaw and simultaneously a turn back angle extend a section (but knuckle be 1/2 α of such scheme) at this moment of sewing jaw, lower end is a long and narrow die cavity equally, effect is identical.
It is long and narrow die cavity that such major-minor body jaw forms lower end after being combined into crushing pair, and changing is still long and narrow die cavity below.
Because long and narrow die cavity is chamber in small, broken bits, its work done will surmount coarse crushing chamber, so be high abrasion districts, and shake, press not substantive generations in chamber broken, wear away atomicly, allow this heavy light symmetrical exchange in abrasion position, be conducive to extend the utilization rate of jaw, reduce disintegrating machine and totally wear away cost.
Improvement crusher chamber design, arranging shakes presses chamber and long and narrow die cavity, promotes crusher chamber function, to improve crushing efficiency, and dexterously composition is shaken to be arranged to that symmetrical expression exchanges be core technology of the present invention for the one end of pressing chamber and the one end that forms long and narrow die cavity.
By set up the pressure chamber that shakes in crusher chamber upper end, make it eliminate to greatest extent the space between material and material, improve material flow density, improve the work doing efficiency of broken stroke, not changing under the prerequisite of the broken any parameter (comprising broken stroke) of jaw, improved significantly crushing efficiency.
The material flow that utilization is shaken and pressed chamber jolt ramming to enter, has improved the density of material flow.Material flow through shaking after having pressed chamber jolt ramming, eliminates the gap between material to greatest extent, and material density improves, and enters the material of crusher chamber fragmentation within the identical broken time, and crushing is corresponding being improved also.
Utilize gravity to stop displacement and the spring of material in shattering process.
Because the broken crusher chamber of jaw is " V " character form structure, big upper and lower small mouth, is an angle during two jaw interlock materials, make material have the component upwards pushing away.Although this angle has been arranged on when design jaw is broken in the limiting angle α (26 °) that maximal friction allows, when material flow is loose, be easy to make that material turns to, displacement or upwards takeoff, affect the effective broken work done of broken stroke.In crusher chamber upper end, set up one and shaken and press behind chamber, a thick layer of material is being pressed in the material top in crusher chamber, and the weight of this layer of material itself is pushed down the material in crusher chamber, plays that prevention material turns to, displacement and upwards jump role.
Make feed more steady.Under prior art condition, due to the impact of all factors, the material that enters disintegrating machine always has some fluctuations, time many when few.This material fluctuation affects output, reduces again service life of equipment.In invention, having set up shakes presses chamber, is equivalent to be provided with a savings material bin, when charging is excessive, by it, is saved, and when too small, by it, mended and is supplied.In in certain degree, play steady feed effect, can constant rate of production, be conducive to again extension device service life.
Jaw is designed to the function after " major and minor body jaw plate structure ".
The solid accumulation that enters crusher chamber is shaky, thereby affects crushing efficiency.We can analyze from three aspects:
1. because broken material is out-of-shape, not of uniform size mostly, between material and material, form very large cavity clearance, so, the material density passing through in the unit interval is reduced, crushing efficiency is insufficient;
2. the broken stroke (the relative motion distance that refers to two jaws) due to every disintegrating machine is certain value, when thering is the material flow in larger gap and enter crusher chamber, will consume in this process of compact stockpile the last period of broken stroke (only has after bank compacting, broken stroke just plays substantial broken work done), so, the loose effective broken work done that has reduced broken stroke of material flow;
3. because the broken crusher chamber of jaw is " V " type structure, big upper and lower small mouth, has one the component that material makes progress is existed during two jaw interlock materials, so, when material loosening, be easy to make that material turns to, displacement or upwards takeoff, thereby affect the effective broken work done of broken stroke.
More than analysis is visible, and the loose or dense degree of material flow is the key factor that affects the broken crushing efficiency of jaw.
As preferably, described main body jaw and accessory body jaw are monolithic construction or split-type structural.
Main body jaw plate structure is that straight line is modal structure; Select the superiority of curvilinear structures to be that jaw bottom crushed particles is less, efficiency is higher; Broken line structure makes crusher chamber be divided into a plurality of chambeies, realizes graded crushing.
As preferably, eccentric drive axis mechanism comprises an eccentric drive shaft, and described Dong E mechanism comprises that Yi Donge， bracket mechanism comprises a bracket;
The upper end of moving jaw is connected with eccentric drive shaft, and lower end is connected with the front end of bracket; The rear end of bracket is connected in frame.
The present invention be can be used for to the broken type of conventional jaw, and, particle size after cracking lower to material hardness also can play certain effect in small, broken bits when not too thin.And also can use on old machine, transformation is than being easier to, and manufacturing cost is relatively cheap.
As preferably, eccentric drive axis mechanism comprises that a pre-eccentric driving shaft and a rear eccentric drive shaft ，Dong jaw mechanism comprise that a front moving jaw and a Hou Donge， bracket mechanism comprise a front bracket and a rear bracket;
The upper end of front moving jaw is connected with pre-eccentric driving shaft, and lower end is connected with the front end of front bracket; The rear end of front bracket is connected with the lower end of rear moving jaw;
The upper end of rear moving jaw is connected with rear eccentric drive shaft, and lower end is connected with the front end of rear bracket; The rear end of rear bracket is connected in frame.
Dual-crank-rocker mechanism is an important component part in the present invention, and its reinforcement effect provides necessary condition for super fine crushing; Its large stroke is adjusted the lamination fragmentation that characteristic is large pilled-in selvedge, large stroke necessary assurance is provided.
The structure functional requirement required for the present invention that prior art jaw is broken.The one, moving jaw bottom work done is stressed limited; The 2nd, large stroke is adjusted limited.
The bracket mechanism of the moving jaw bottom of prior art jaw crusher is irrational, has " subtracting stress effect ", and its motion be take discharges material as major function, so the motion of moving jaw bottom is the stroke of discharge, rather than broken stroke.Be accompanied with some crushing functions, very little and loss very large (subtracting power effect because exist).This is intrinsic disadvantage and the weakness of prior art jaw crusher.
The remarkable result of dual-crank-rocker mechanism jaw crusher is to have broken through the limitation that jaw crusher in prior art is only used a set of crank and rocker mechanism, the present invention uses the one in front and one in back combination of two cover crank and rocker mechanisms, eliminated the two conflicting drawback of prior art jaw crusher discharges material and broken work done, make a crusher there is the effect of two-stage crushing, make broken material more carefully, more even, fully saved again resource.
As preferably, eccentric drive axis mechanism comprises a pre-eccentric driving shaft and a rear eccentric drive shaft; Dong E mechanism comprise the moving jaw of going forward, once before on moving jaw, after moving jaw and moving jaw afterwards once; Bracket mechanism comprise the bracket of going forward, once before on bracket, after bracket and once after bracket;
The go forward upper end of moving jaw is connected with pre-eccentric driving shaft, and lower end is connected with the front end of the bracket of going forward; The go forward rear end of bracket and the lower end of upper rear moving jaw is connected;
After upper, the upper end of moving jaw is connected with rear eccentric drive shaft, and lower end is connected with the front end of upper rear bracket; After upper, the rear end of bracket is connected in frame;
Before lower, the upper end of moving jaw is connected with the lower end of the moving jaw of going forward, and lower end is connected with the front end of lower front bracket; The lower rear end of front bracket and the lower end of lower rear moving jaw are connected;
After lower, the moving upper end of jaw and the lower end of upper rear moving jaw are connected, and lower end is connected with the front end of lower rear bracket; After lower, the rear end of bracket is connected in frame.
" composite multi-crank rocker mechanism design " than Double crank rocker structure more superiority be: the latter only has moving jaw bottom to have reinforcement effect, the former moving jaw all have up and down reinforcement effect, be more conducive to super fine crushing.
With " composite multi-crank rocker mechanism design " replacement " dual-crank-rocker mechanism design ", make jaw upper and lower part jointly there is the crushing force of " reinforcement effect ", and overcome the congenital drawback of the broken half way work done of prior art jaw, realized omnidistance work done.The bright spot that adopts composite multi-crank rocker mechanism maximum is that the fragmentation campaign of moving jaw horizontal direction and the flip-flop movement of vertical direction are separated into self-movement, and " the crushing Cracking Mechanism " of jaw crusher is promoted to " selective crushing " this efficient Cracking Mechanism.
