Description

A kind of negative interlock angle staged crusher chamber
Technical field
The utility model relates to the disintegrating apparatus technical field, more specifically says a kind of negative interlock angle staged crusher chamber.
Background technology
Jaw crusher also claims jaw broken, with a long history." big family " at disintegrating machine is inner, jaw broken simple in structure with it, cost is low, the power consumption abrasion are low and easy to maintenance and become one of most popular disintegrating apparatus.
Jaw is broken to be typical " thick broken " equipment.
Thick broken two connotations that have here:
One, the material that goes out of the broken fragmentation of jaw is very thick, and namely the broken broken fines of jaw is difficult to (this is relevant with the broken breaking cavity structure of jaw), and it is just very difficult usually to be crushed to the following granularity of 30mm.
Two, the material that goes out of the broken fragmentation of jaw is primary product (grain shape of product is pin, sheet, and is very serious, and modern engineering construction all requires product to be the cubic granules shape).So the rubble production line in the reality all is placed on chopped-off head or two-stage crushing with the broken equipment of jaw, other broken machines such as counterattack is broken, impact cutting are then selected in the final stage fragmentation, because the particle that these two machine fragmentations go out is cubic, product quality is high.The disintegrating machine that is placed on final stage claims " shaping " disintegrating machine, also claims by " trimmer ".And counterattack is broken, the power consumption of impact cutting and abrasion much higher with respect to jaw is broken (wearing and tearing that for example jaw is broken are the broken 1/3-1/5 of counterattack, and power consumption is the 1/3-1/2 of impact cutting).
Obviously, the material that the broken fragmentation of jaw goes out is " elementary " product, and jaw is broken to be " slightly " equipment.If can realize " shaping " crushing function with the broken equipment of jaw, namely use the work of equipment dried " carefully " level of " slightly " level, the lifting amplitude of its economic benefit is greatly considerable!
Broken " shaping " crushing function that lacks of prior art jaw, its limitation is:
The one, " breaking chamber structure " is unreasonable." shaping " from " fragmentation ' different mechanism be that the former requires snap-in force larger, to material to mix motion stronger.Breaking chamber structure under the prior art is unfavorable for shaping.
The 2nd, " Cracking Mechanism ' unreasonable.Shaping needs the Cracking Mechanism of " selective crushing ", does not possess and the prior art jaw is broken.(under selective crushing mechanism, material is broken along weakness, and namely the needle-like material is broken along weakness, flat-shaped material is then broken along thin place, finally makes material be cubic.)
Therefore, wish realizes shaping feature with jaw crusher, just should break through from the innovative design of crusher chamber and the lifting of Cracking Mechanism.
The utility model content
The purpose of this utility model is significantly to promote the ratio of reduction of jaw crusher, and a kind of negative interlock angle staged crusher chamber that can make jaw crusher realize broken fines and shaping feature is provided.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of negative interlock angle staged crusher chamber is characterized in that: comprise two jaws, comprise two jaws, at least one of them has above broken line structure twice, and this two jaws face-off forms the staged crusher chamber;
The staged crusher chamber size that described two jaw working faces face-off forms from top to bottom diminishes gradually by level, and the shape of every grade of crusher chamber is presented little lower macrostructure;
The angle direction that two jaw working faces of composition trapezium structure crusher chamber two waists form is downward.
Of the present utility model two large significantly architectural features are: 1. crusher chamber is stepped construction chamber type feature; 2. the angle that forms of two jaw working faces is negative angle (the broken V-shaped structure of crusher chamber of jaw in the prior art, two jaw angles upwards are defined as positive angle, the angle that the utility model jaw working face forms is downward, is defined as negative angle).
The technical solution of the utility model is: (method of " classification, translation, negative angle " trilogy)
1. classification.Jaw in the conventional crusher chamber is divided into Luo Gan's section (such as being divided into 4 sections);
2. translation.The respectively outside translation of after cutting apart each section jaw namely becomes large with crusher chamber segmentation expansion from the bottom to top;
3. negative angle.The angle that the plane of disruption of two jaws forms is downward.
" shaping is broken " of the present utility model mechanism is such:
Realize by the innovative design of " negative interlock angle staged crusher chamber " and efficiently " crusher reason " utilization:
One, " negative interlock angle staged crusher chamber " design
As mentioned above (technical scheme), by classification, translation, negative angle innovative design behind the new chamber type, supporting following 2 points again:
1. feed particles is of a size of 1/3~1/5 of crusher chamber inlet size; One of important difference of two kinds of operations of shaping and fragmentation is exactly charge ratio different (the charging size of crushing operation and crusher chamber inlet size be 1:1 almost).Plastic operation is not direct broken material, but the material after the fragmentation of last road is made " lamination is broken " again, only pin, flat-shaped particle are being carried out grain dressing by " selective crushing mechanism ", the charge ratio of above-mentioned setting is the precondition that realizes the lamination fragmentation.
2. at a high speed (more than 330 rev/mins), large stroke (the broken stroke of conventional jaw 2~5 times).Lamination is broken closely related with rotating speed, and the bed of material has elasticity, and under high speed, the material in the bed of material is finished broken work done with regard to moment before having little time displacement and dodging, and speed is crossed slow lamination fragmentation and descended.Large stroke also produces large the stirring except producing the lamination effect, realize selective crushing mechanism.(selective crushing mechanism will satisfy two conditions: 1. strengthen gradually, enough strong pressure; 2. the material all directions are stressed and rolling).
Two, in " lamination is broken ", realize " selective crushing mechanism "
" selective crushing mechanism " is exactly, makes material broken along weakness, and namely the needle-like material is broken along weakness, flat-shaped material is then broken along thin place, finally makes material be cubic.
The lamination fragmentation is for single fragmentation, single fragmentation be between two jaws be single material in fragmentation, be the jaw pressing materials; The lamination fragmentation is that many materials are arranged between two jaws, and is stressed around the material, is the material pressing materials.
" lamination broken " reach " selective crushing mechanism " is to form under the motion feature condition of sewing jaw " large slack list, the large bed of material, large stroke, greatly stirring and large pilled-in selvedge ".(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 that pilled-in selvedge, stroke begin to claim the slack list when also namely two jaw bottoms are in ultimate range, and the difference of the size of slack list and pilled-in selvedge also is 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;
" large stroke " motion feature makes material produce enough lamination pressures and large the stirring;
" the large stirring " motion feature is realized " selective crushing mechanism ";
" large pilled-in selvedge " motion feature makes crusher chamber be in all the time " lamination " state.
Generally speaking, the broken type of jaw will be realized shaping feature, 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 " and " selective crushing mechanism " are cores.
Remarkable functional character of the present utility model is: the shaping feature of realizing the broken equipment type of jaw.Such as the again improvement of supporting crusher structure (such as dual-crank-rocker mechanism disintegrating machine, composite multicrank rocker mechanism crushing machine), significantly promote the jaw crusher function, improve to greatest extent crushing efficiency and reduce power consumption.
In sum, using the technical measures of " classification, translation, negative angle ", the crusher chamber of prior art is promoted to the structure with shaping feature, is core technology of the present utility model.It has been broken through the prior art crusher chamber and has been only suitable for the limitation that fragmentation is not suitable for shaping, has promoted significantly the function of jaw crusher.
Jaw is broken to be " slightly " equipment, and " shaping " is to live " carefully ", and allowing " slightly " equipment do " carefully " work is an energy-saving and cost-reducing green revolution! Type with the broken equipment of jaw is realized " shaping " function, 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. improve discharges material speed, thereby improve output.The broken speed of jaw under the prior art is the free-fall velocity of object nature, and this has been a limiting value, and the utility model has been broken through this limiting value.
Jaw shaped negative angle structures in the utility model crusher chamber, its jaw has a quick propulsive force (if eccentric shaft turn to be set to consistent with the logistics direction) to material in broken motion process, and this will increase substantially jaw bankruptcy amount.
2. 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, the tooth-shape structure on the two jaw working faces from top to bottom also diminishes by level gradually, namely tooth depth by level gradually step-down, the facewidth narrows down gradually by level and space width diminishes gradually by level.
Be fed to the situation that particle diminishes gradually the process of crusher chamber lower end discharging for adapting to material from the crusher chamber upper end, again crusher chamber is designed to profile of tooth hierarchic structure, be that the tooth-shape structure size diminishes gradually by level from top to bottom, the formula large granular materials is broken under large tooth-shape structure, small particles material is then broken under little tooth-shape structure, reaches the highest crushing efficiency.
As preferably, be positioned at two jaw working face sleeve configuration structures of lower end afterbody crusher chamber in the staged crusher chamber, the two jaw working face angle angular ranges that form the sleeve configuration structure are-8 degree~+ 8 degree; The length of sleeve configuration structure is 110~550mm.。
The sleeve configuration crusher chamber is core technology bright spot of the present utility model, and five large features are arranged:
1, shape facility.The lateral cross section length of sleeve configuration crusher chamber is longer, and width is narrower, i.e. the openning prolate; Vertically (broken direction) degree of depth is darker; 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;
2, angle character.The sleeve configuration crusher chamber is take the pilled-in selvedge state as standard, and its angle is-5~+ 5 degree, and it is unobstructed to be conducive to discharge when choosing negative angle, is conducive to the lamination fragmentation when choosing positive-angle, when choosing zero degree then the material of arranging the most even;
3, volume characteristic.The volume size of sleeve configuration crusher chamber is the each time withdrawal rate of working cycles of disintegrating machine, and chamber type pilled-in selvedge size is got 1~3 times of discharge particle size.
4, motion feature.The sleeve configuration crusher chamber has the motion feature of " large pilled-in selvedge, large stroke ";
5, functional character.The sleeve configuration crusher chamber has " lamination is broken " mechanism, and discharging is ultra-fine.
The mechanism of the broken chamber type sand powder process processed of jaw of the present utility model is to form like this:
1, be designed to bottom " sleeve configuration crusher chamber " in crusher chamber, the raw meal particle size that each working cycles of crusher chamber is given off is controlled in the required size scope, realizes even broken;
2, the upper end of every grade of crusher chamber guarantees charging fully (be particle size less than charging aperture, flow greater than volume), and one-level cover one-level, angulation hierarchic structure, thus improve sleeve configuration crusher chamber operating efficiency;
3, be fed to the situation that particle diminishes gradually the process of lower end discharging for adapting to material from the crusher chamber upper end, crusher chamber is designed to profile of tooth hierarchic structure, be that the 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 evenly purpose in small, broken bits;
4, the fragmentation campaign that is aided with " large pilled-in selvedge, large stroke " realizes " lamination is broken ".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.Do not realize with the thinking ultrafine grinding (sand processed, powder process) of " single Cracking Mechanism " 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 just are difficult to reach, 2, output is also very little under the so thin Micro-chamber, almost without practicality.
And the fragmentation campaign of " large pilled-in selvedge, large stroke " realizes " 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 is " large stroke ", and inlet amount is large under the large stroke, and the high pressure that produces under the high ratio of reduction when large pilled-in selvedge is broken, shows as the crusher reason.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.
The fragmentation campaign of " large pilled-in selvedge, large stroke " then can realize " lamination is broken " mechanism, and so-called " lamination fragmentation " is exactly between shattering process lumen type the multilayer particle material to be arranged, and the mode by the material pressing materials realizes in small, broken bits.Like this, chamber type pilled-in selvedge size is particle size not necessarily just, and larger pilled-in selvedge also can be broken excess of export fines (such as the chamber type pilled-in selvedge size of 10~20mm, can be broken going out the following powder of 0.15mm).
As preferably, form that one of them is the planar light plate structure at least in the two jaw working faces of sleeve configuration structure.
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 staged crusher chamber is two-stage, three grades or level Four hierarchic structure.
The multiple stage crushing chamber is bright spot of the present utility model, and required progression is relevant with the type size, and little type progression can lack, and large type progression should be many.
As preferably, every grade of crusher chamber shape is left-right symmetry structure or left and right sides unsymmetric structure in the staged crusher chamber.
As preferably, two jaws of staged crusher chamber are respectively the integral die-cast moulding or are the split spicing forming type.
The overall structure superiority is the device structure simplification, and it is convenient to change; The Split type structure stock utilization is high, changes each time only to need to change to may wear to a fritter at the end and get final product.
