Summary of the invention
The object of the invention is to overcome the defect that prior art jaw crusher can not be in small, broken bits, provide a kind of simple in structure, cheap, crushing efficiency is high, the province's power consumption that saves time, can be by bulky grain raw material Direct Uniform jaw formula sand powder disintegrating machine in small, broken bits.Break the limitation that the types such as prior art utilization hammer, roll-type, impact type can be in small, broken bits through multiple stage crushing, simplify the flow process of mining production line.
In order to reach above object, the present invention is achieved by the following technical solutions: a kind of jaw formula sand powder disintegrating machine, comprise frame, eccentric drive axis mechanism ,Dong jaw mechanism, bracket mechanism and crushing pair mechanism, described crushing pair mechanism is comprised of main fixed jaw and main sewing jaw, the working face face-off of main fixed jaw and main sewing jaw forms main crusher chamber, and the working face of main fixed jaw and main sewing jaw is provided with tooth-shape structure; It is characterized in that,
Described main fixed jaw and the bottom of main sewing jaw are extended respectively and are connected with secondary fixed jaw and secondary sewing jaw, and the secondary crusher chamber that the working face face-off of secondary fixed jaw and secondary sewing jaw forms is sleeve configuration structure;
In described secondary fixed jaw and secondary sewing jaw, have at least the working face of to be set to planar light plate structure.
Architectural feature of the present invention: " sleeve configuration structure " and " planar light plate structure " is of the present invention two large significantly architectural features.The secondary crusher chamber of a sleeve configuration structure is set in the lower end of main crusher chamber, and in two jaw working faces of the secondary crusher chamber of composition sleeve configuration structure, at least one of them is planar light plate structure.
Remarkable functional character of the present invention is: make jaw crusher have the function of even broken fines.
The material that fragmentation goes out has two large features:
The one, " carefully "; So-called " carefully ", exactly the material that goes out of fragmentation much thinner than the prior art jaw crusher of same size model;
The 2nd, " evenly ".So-called " evenly " is exactly that its granular size can concentrate in the specification limit of required finished product material to greatest extent, and product particle size concentration degree is high.
Core technology of the present invention is: the utilization of managing by sleeve configuration structure crusher chamber design and crusher, promoted the crushing function of jaw crusher, and make to be originally that the jaw crusher of coarse smash equipment is realized material evenly in small, broken bits.
The even mechanism in small, broken bits of the present invention combines to realize by science " sleeve configuration crusher chamber " design and " crusher reason " utilization efficiently:
1. " sleeve configuration crusher chamber " design
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.And guarantee that each volume discharging is all the material in this sleeve configuration structural area, do not allow epicoele material omit in printing.The length of sleeve configuration structure is determined by freely falling body rule.
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 design of sleeve configuration structure crusher chamber is of the present invention one large technological highlights.
The designing requirement of sleeve configuration structure crusher chamber:
(1) 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) 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; Determining of length L: press freely falling body formula h=1/2*g*t2 calculating, the broken rotating speed of prior art jaw, at 180~330 revs/min, calculates length L between 110~550 millimeters;
(3) angle of the secondary crusher chamber of sleeve configuration can be selected between-8~+ 8 degree, and notes following 3 points:
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. to be conducive to material broken evenly for zero degree, 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, thus 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 what study and hold is an angular range, and the applicant is set between-8~+ 8 degree.
2. " crusher reason " used
The function even in small, broken bits of above-mentioned sleeve configuration structure crusher chamber has significant limitation:
When raw meal particle size reaches the rank of sand and powder (4.75-0.15mm particle is called sand, and 0.15mm is hereinafter referred to as powder), under Cracking Mechanism of Single Granule, the fine dimension that crusher chamber gap is adjusted to sand and powder is unrealistic.Because the accuracy of manufacture, installation accuracy or the performance accuracy that are no matter jaw all can not meet its requirement, even if can meet, its output is also atomic, there is no Practical significance.So the present invention is on the basis of design sleeve configuration crusher chamber, " the crusher reason " of uses advanced is to reach evenly object in small, broken bits.
So-called " lamination is broken " is exactly to have the granule materials flocking together in shattering process lumen type, and the mode by material pressing materials realizes in small, broken bits.Individual particle fragmentation is jaw pressing materials; Lamination fragmentation is between two jaws, to have the material flocking together in mutual extruding.
Lamination fragmentation be under the motion feature condition of sewing jaw " large slack list, the large bed of material, large stroke, large pilled-in selvedge ", form (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 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 stroke).
" large slack list " motion feature can make crusher chamber be filled with enough materials, forms material bed (the large bed of material) of adequate thickness;
It is broken that " large stroke " motion feature makes material produce desirable lamination;
" large pilled-in selvedge " motion feature makes crusher chamber can under the state of non-fine clearance chamber type, realize the evenly in small, broken bits of material.
Jaw crusher is typical single Cracking Mechanism, and when broken coarse fodder, the pilled-in selvedge size of basic epicoele type is exactly the particle size of material.With the thinking ultrafine grinding (powder process) of " single Cracking Mechanism ", miss one's aim separately, because chamber type pilled-in selvedge size is transferred to the words of powder particle sizes, so: 1, the accuracy of manufacture of chamber type and installation accuracy are difficult to reach, 2, output is also very little under so thin Micro-chamber, without practicality.
And the fragmentation campaign of " large pilled-in selvedge, large stroke " can realize " crusher reason ", 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 also 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 " determines ultra-fine particle, determines higher output again.
2. the design of planar light plate structure:
When particle is the rank of sand, powder, tooth-shape structure has lost broken meaning, and 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.
Planar light plate structure design be the present invention another large technological highlights.
3. the lifting of disintegrating machine mechanical structure
In using " lamination is broken " mechanism, need to there is the jaw motion feature of " large stroke " and there is enough " reinforcement effect ”Zhi mechanics mechanisms, this is relevant to the overall structure of crusher, prior art jaw breaks does not possess this two conditions, and before the applicant, dual-crank-rocker mechanism disintegrating machine and the compound crank and rocker mechanism disintegrating machine of application meet above-mentioned condition.
Generally speaking, the broken type of jaw will be realized ultrafine grinding function, and large " key element " is integrated forms by three: " chamber type+type+mechanism ".
The innovative design of " sleeve configuration structure ", " stepped construction " crusher chamber is basis;
" dual-crank-rocker mechanism disintegrating machine " and " compound crank and rocker mechanism disintegrating machine " is necessary and sufficient condition;
" crusher reason " is core.
Remarkable functional character of the present invention is: realize crushing function extraordinary, ultrafine grinding.As the improvement of supporting crusher structure again (as the applicant's innovative design: dual-crank-rocker mechanism disintegrating machine, the compound crank and rocker mechanism disintegrating machine of the patent No., the patent No.), the present invention can realize the directly broken sand processed of unit, even broken powder process.Not only significantly promote jaw crusher function, and improve to greatest extent crushing efficiency and reduce power consumption.Also greatly simplify mining production line flow process simultaneously.
Jaw is broken is " slightly " equipment, and sand processed, powder process are " carefully " work, and allowing " slightly " equipment do " carefully " work is an energy-saving and cost-reducing green revolution! With the broken type of jaw, realizing sand processed, powder process, is a great technological revolution in field of cracking machine!
Except above-mentioned remarkable functional character, the beneficial effect simultaneously bringing also has:
1. improve output.As being designed to shaped negative angle structures (referring to two plane of disruption angles) at breaking chamber structure of the present invention, 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 lower jaw is broken is natural free-fall velocity, is a limiting value.The present invention has broken through this limit velocity.
2. improve the ratio of reduction.As being the segmentation structure of bypassing the immediate leadership by stepped structural design in crusher chamber of the present invention, can increase substantially so the ratio of reduction of disintegrating machine, improve the crushing performance of disintegrating machine.
3. reduce abrasion.The crusher reason of uses advanced of the present invention, has the material of considerable part to be " material dnockout ", and therefore abrasion greatly reduce.
As preferably, tooth-shape structure on described secondary fixed jaw and secondary sewing jaw working face is equal to or less than the tooth-shape structure on the working face of described main fixed jaw and main sewing jaw, and tooth depth, the facewidth and the space width of secondary fixed jaw and secondary sewing jaw working face are equal to or less than tooth depth, the facewidth and the space width on main fixed jaw and main sewing jaw working face.
Tooth-shape structure is tapered design principle from top to bottom: when particle diameter and tooth pitch approach, and the broken defunctionalization of folding of tooth-shape structure; When particle diameter and profile of tooth size approach, tooth-shape structure split broken defunctionalization.So after material fragmentation is little, profile of tooth should in good time suitablely diminish, and so just has higher crushing efficiency.
As preferably, described secondary fixed jaw and secondary sewing jaw wherein have the working face of to be set to planar light plate structure.
As the alternative of such scheme, the working face that described secondary fixed jaw and secondary sewing jaw are two is all set to planar light plate structure.
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 broken direction length of the secondary crusher chamber of described sleeve configuration planar light plate structure is 110~550mm; The angle angular range of the secondary crusher chamber of described sleeve configuration planar light plate structure is-8~+ 8 degree.
As preferably, the structure of described main fixed jaw and main sewing jaw is straight line, curve or broken line structure.Secondary fixed jaw and secondary sewing jaw that described main fixed jaw and main sewing jaw are corresponding with it are all structure as a whole or Split type structure.
The structure of main fixed jaw and main sewing jaw 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 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 little 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;
