Description

A kind of sleeve configuration structure crushing pair
Technical field
The utility model relates to the disintegrating apparatus technical field, more specifically says a kind of sleeve configuration structure crushing pair.
Background technology
Jaw crusher also claims jaw broken, is with the longest history, one of most popular disintegrating apparatus.
Jaw is broken to be typical " thick broken " equipment.
Thick broken two connotations that have here:
One, jaw is broken is not precision equipment, (machine tool just can be competent at) simple in structure, easy to manufacture, use and keep in repair all and make things convenient for, 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 is relevant with the breaking cavity structure that jaw breaks, and usually is crushed to the following particle of 30m and just has been difficult to.
If can namely use the work of the equipment dried " level in small, broken bits " of " thick broken level " with the broken broken fines of jaw, its economic benefit then can significantly promote.
The broken crushing pair of prior art jaw combined symptoms can not be evenly in small, broken bits is:
The one, the angle unreasonable structure of crusher chamber.Be the crusher chamber of " V " type after each circulation stroke work done, discharge be the material of a pile triangle volume.Typical individual particle broken (do not have lamination broken) because jaw is broken, so the granular size set of dimensions moderate of triangle volume is poor, it is high that the on-the-sieve material (material that surpass up to specification size) of discharging after screening returned heavily broken ratio, affects crushing efficiency;
The 2nd, Cracking Mechanism is unreasonable.The prior art jaw crusher is Cracking Mechanism of Single Granule, the particle size of discharging finished product and crusher chamber gap size directly are equivalent to, be that great crusher chamber gap just goes out great product, but the gap of crusher chamber is subjected to the structural limitations can not be too little, so restricted the broken function in small, broken bits of jaw (such as the rank of the critical sand of particle size in small, broken bits time then can't be in small, broken bits again).
Therefore, want to make the broken fines of the broken type of jaw and even direct, will break through at innovative design and its Cracking Mechanism of change of crushing pair.
The utility model content
The purpose of this utility model is to overcome the not high defective of prior art crusher chamber crushing efficiency, and the sleeve configuration structure crushing pair that is used for jaw crusher of a kind of crushing efficiency height, the province's power consumption that saves time, the broken fines of energy is provided.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of sleeve configuration structure crushing pair, comprise 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:
The bottom of described main fixed jaw and main sewing jaw is extended respectively and is 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 the sleeve configuration structure;
The broken direction length of the secondary crusher chamber of described sleeve configuration structure is 110~550mm.
The angle angular range of the secondary crusher chamber of described sleeve configuration structure is-8~+ 8 degree.
Remarkable architectural feature of the present utility model is: the secondary crusher chamber that a sleeve configuration structure is set in the lower end of main crusher chamber.The broken direction length of the secondary crusher chamber of this sleeve configuration structure is 110~550mm.
Remarkable functional character of the present utility model is: make jaw crusher have the function of even broken fines.
The material that fragmentation goes out has two large characteristics:
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 namely product particle size concentration degree is high.
Core technology of the present utility model is: by the utilization of sleeve configuration structure crusher chamber design and crusher reason, promoted the crushing function of jaw crusher, making is that the jaw crusher realization material of coarse smash equipment is evenly in small, broken bits originally.
The even mechanism in small, broken bits of the utility model combines to realize by science " sleeve configuration crusher chamber " design and efficiently " crusher reason " utilization:
1. " sleeve configuration crusher chamber " design
Eccentric shaft turns around, a broken circulation, and the material that discharges is the volume in a del district of crusher chamber bottom.Analyzing first extreme case, under the type state of inverted triangle chamber, is that the gap of crushing pair two jaw lower ends transfers to zero (surpass zero will cause jaw to bump against and ruin machine) even floss hole transfers to minimum, still can give off coarse fodder.
And under the sleeve configuration structural capacity, can the floss hole size be set according to required material finished size size fully.And guarantee that each volume that discharges all is the material in this sleeve configuration structural area, does not allow the epicoele material omit in printing.
Obviously, the bottom is provided with the crusher chamber of sleeve configuration structure, and is 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) 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, and particle is controlled at trimmed size material size range;
(2) length of sleeve configuration crusher chamber should satisfy the required height of each broken recycle stock freely falling body, can not allow material in the main crusher chamber alter to slip and descends; Determining of length L: press freely falling body formula h=1/2*g*t2 and calculate, the rotating speed that the prior art jaw breaks calculates length L between 110~550 millimeters at 180~330 rev/mins;
(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, excessively is unfavorable for even fragmentation;
3. to be conducive to material crushing even for zero degree, but because sewing jaw is the fan shape moving take eccentric shaft as the center of circle, and jaw is among continuous wearing and tearing change, thus zero degree only be 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 reached 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 the crusher chamber gap is transferred to sand and powder was unrealistic.Because the accuracy of manufacture, installation accuracy or the performance accuracy that no matter are jaw all can not satisfy its requirement, even if can satisfy, its output is also atomic, does not have Practical significance.So the utility model is on the basis of design sleeve configuration crusher chamber, " the crusher reason " of uses advanced is to reach evenly purpose in small, broken bits.
So-called " lamination is broken " is exactly in shattering process lumen type the granule materials that flocks together to be arranged, and the mode by the material pressing materials realizes in small, broken bits.The individual particle fragmentation is the jaw pressing materials; The lamination fragmentation then is the material that flocks together to be arranged in mutual extruding between two jaws.
The 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 to claim when namely two jaw bottoms are in minimum range pilled-in selvedge, stroke to begin to claim the slack list when namely two jaw bottoms are in ultimate range, 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 realize the evenly in small, broken bits of material under the state of non-fine clearance chamber type.
Jaw crusher is typical single Cracking Mechanism, and the pilled-in selvedge size of basic epicoele type is exactly the particle size of material when broken coarse fodder.Thinking ultrafine grinding (powder process) with " single Cracking Mechanism " misses 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, and 2, output is also very little under the so thin Micro-chamber, without practicality.
And 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 that " large stroke " produces, and the multilayer particle material is arranged 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 that 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 following powder of 0.15mm).The origin cause of formation that forms chamber type high pressure fragmentation be " large stroke ", inlet amount is large under the large stroke, the high pressure that produces under the high ratio of reduction when large pilled-in selvedge is broken, shows as the 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 " namely determines ultra-fine particle, determines higher output again.
3. the lifting of disintegrating machine mechanical structure
In using " lamination is broken " mechanism, need to have the jaw motion feature of " large stroke " and the mechanics mechanism with enough " reinforcement effect ", this overall structure with crusher is relevant, the prior art jaw breaks does not possess this two conditions, and dual-crank-rocker mechanism disintegrating machine and the compound crank and rocker mechanism disintegrating machine of application meet above-mentioned condition before the applicant.
Generally speaking, the broken type of jaw will be realized the ultrafine grinding function, and large " key element " is integrated forms by three: " chamber type+type+mechanism ".
1. the innovative design of " sleeve configuration structure ", " stepped construction " crusher chamber is the basis;
" dual-crank-rocker mechanism disintegrating machine " to reach " compound crank and rocker mechanism disintegrating machine " be necessary and sufficient condition;
3. " crusher reason " is core.
Remarkable functional character of the present utility model is: realize crushing function extraordinary, ultrafine grinding.Such as the again improvement of supporting crusher structure (dual-crank-rocker mechanism disintegrating machine or the compound crank and rocker mechanism disintegrating machine applied in the early time such as the applicant), the utility model can be realized the directly broken sand processed of unit even broken powder process.Not only significantly promote the jaw crusher function, and improve to greatest extent crushing efficiency and reduce power consumption.Also greatly simplify simultaneously mining production line flow process.
Jaw is broken to be " slightly " equipment, and sand processed, powder process are " carefully " work, allows dried " carefully " work of " slightly " equipment be an energy-saving and cost-reducing green revolution! Realizing sand processed, powder process with the broken type of jaw, is a great technological revolution in the field of cracking machine!
Except above-mentioned remarkable functional character, the beneficial effect that brings simultaneously also has:
1. raising output.As be designed to shaped negative angle structures (referring to two jaw crushing working face angles) at the utility model breaking chamber structure, then in broken motion process, its jaw has a quick propulsive force (if eccentric shaft turn to be set to consistent with the logistics direction) to material.This will increase substantially jaw bankruptcy amount.
Because the broken speed that the prior art lower jaw is broken is the free-fall velocity of nature, is a limiting value.The utility model has been broken through this limit velocity.
2. the raising ratio of reduction.As being the segmentation structure of bypassing the immediate leadership with stepped structural design in the utility model crusher chamber, 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 the utility model uses advanced namely 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 the 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 namely 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 the main sewing jaw working face.
Tooth-shape structure is tapered design principle from top to bottom: when particle diameter and tooth pitch near the time, the broken defunctionalization of the folding of tooth-shape structure; When particle diameter and profile of tooth size near the time, tooth-shape structure split broken defunctionalization.So after material crushing was little, profile of tooth should in good time suitablely diminish, and so just has higher crushing efficiency.
As the alternative of such scheme, described secondary fixed jaw and secondary sewing jaw have at least one working face to be set to solid slab construction.
The design principle of planar light plate structure: when particle was the rank of sand, powder, tooth-shape structure had lost broken meaning, and available flat board is for it, was that with the superiority of slab construction discharges material is more abundant, because there is not tooth pitch to take type space, chamber.
The planar light plate structure is exactly tooth depth, the facewidth and the space width limiting condition when being zero, and it is the structure that falls behind, eliminate 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, be promoted as " mill " from " breaking ", mill is ultrafine grinding (sand processed, powder process) better then.
In sleeve configuration structure chamber, planar light plate structure jaw has following superiority:
1. for the fines rank, no longer need " split broken, folding is broken, squeeze broken " etc. the effect finished of need tooth-shape structure, 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 latter's interlocking pattern is better, and fine granules is more even.
In one section planar light plate structure of the lower end (in the sleeve configuration structure chamber) of crusher chamber design, it is the another technological highlights in the utility model.
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 all are 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, efficient is higher; The broken line structure then makes crusher chamber be divided into a plurality of chambeies, realizes graded crushing.
