Description

A kind of large reduction ratio jaw crusher
Technical field
The utility model relates to the disintegrating apparatus technical field, more specifically says a kind of large reduction ratio jaw crusher.
Background technology
Jaw crusher also claims jaw broken, is with the longest history, one of most popular disintegrating apparatus.
Wherein crusher chamber is one of important feature parts in the crusher, and crusher chamber is comprised of two jaw face-offs.The structure of the crusher chamber of jaw crusher is positive v-shaped cavity type, and material enters from suitable for reading, along with the shattering process particle diminishes and down motion, until discharge.
The ratio of reduction is to weigh an important indicator of disintegrating machine performance, and the prior art jaw crusher improves the ratio of reduction and mainly is limited by the following aspects factor:
One, is subjected to the restriction of breaking chamber structure
1. angle factor: the angle that two jaws form is called the angle of engagement, and obviously, the angle of engagement is larger, suitable for reading and the end opening ratio of crusher chamber is larger, and namely the ratio of reduction is larger, but it is subjected to material physical characteristic (coefficient of friction) restriction, usually can not surpass 26 degree, surpass the just not blanking of this extreme angles.So the limiting value of the angle of engagement has restricted the lifting of the ratio of reduction;
2. height factor: when the angle of engagement was certain value, the height that promotes crusher chamber can improve the ratio of reduction, but the height of crusher chamber is subjected to disintegrating machine overall structure limitation in height, can not be too high.So the broken complete machine height of jaw has also restricted the lifting of the ratio of reduction.
Two, be subjected to the restriction of the broken structure of jaw
There is " subtracting stress effect " drawback in the broken motor-driven jaw of prior art bottom, let alone possesses the Cracking Mechanism that needs larger crushing force along with broken fines.
Therefore, realize the large reduction ratio crushing function of jaw crusher, just must reach from " innovative design of crusher chamber ", " improvement of crusher structure " " science of Cracking Mechanism is used " and break through.
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 large reduction ratio jaw crusher that can make jaw crusher realize broken fines function is provided.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of large reduction ratio jaw crusher, comprise frame, eccentric drive axis mechanism, moving jaw mechanism, bracket mechanism and crushing pair mechanism, it is characterized in that, described crushing pair mechanism is comprised of the planes of disruption of two face-offs, and one of them is constituted up and down by the polylith jaw at least;
The polylith jaw that forms the same plane of disruption separate to form the ladder grade formula structure that jumps;
The polylith jaw that forms the same plane of disruption becomes the jaw face-off of the offside plane of disruption to form the staged crusher chamber with respective sets, staged crusher chamber size becomes large by the level expansion from the bottom to top.
Remarkable architectural feature of the present utility model is: 1. crusher chamber is stepped construction; 2. crusher chamber is the large stepped construction of grading extension change from the bottom to top by level.
The technical solution of the utility model is: the jaw in the conventional crusher chamber is divided into some sections (such as being divided into 4 sections) 1.; 2. respectively outside translation of each section jaw after cutting apart namely becomes large with crusher chamber segmentation expansion from the bottom to top; 3. the jaw after the crusher chamber grading extension can be Split type structure, also can be overall structure.
Using the method for " segmentation expansion ", the crusher chamber staged is become large (from the bottom to top), is core technology of the present utility model, and it has broken through the limitation of prior art v-shaped cavity type to the ratio of reduction, has promoted significantly the crushing performance of jaw crusher.
The mechanism of large reduction ratio crushing function of the present utility model is such:
Use the method for " segmentation expansion ", the crusher chamber staged is become large (from the bottom to top), innovative design behind the new crusher chamber type, supporting with " large stroke " (conventional jaw is broken 2~5 times of stroke) motion feature again, make the particle size of the material in the upper level crusher chamber can be less than the slack list size of next stage crusher chamber, so that in each broken circulation, the material of upper level crusher chamber can both fully enter the next stage crusher chamber, to guarantee crushing efficiency.
Core technology of the present utility model: use the method for " segmentation expansion ", the crusher chamber staged is become large (from the bottom to top), make disintegrating machine improve the ratio of reduction, the lifting crusher crushing performance is core technology of the present utility model.The raising of the ratio of reduction can also make crushing production line from the long line line that shortens, and advances the technological progress of crushing production line.
Remarkable functional character of the present utility model is: make jaw crusher have the large reduction ratio function.
Large reduction ratio needs the jaw motion feature of " large stroke " supporting, such as the again improvement of supporting crusher structure (such as the dual-crank-rocker mechanism disintegrating machine), significantly promotes the jaw crusher function and usage, improves to greatest extent crushing efficiency and reduces power consumption.
Except above remarkable functional character, also have following beneficial effect:
1. take this opportunity to improve broken snap-in force.
Under the type of the V-arrangement crusher chamber chamber of prior art, allow the ratio of reduction maximize, then make its angle maximization, but angle is large, snap-in force is just poor; And want the snap-in force maximization, its angle is minimized.The angle of crusher chamber (being the angle of engagement) is less, and then snap-in force is larger, but angle is little, and the ratio of reduction just descends; Therefore the ratio of reduction and snap-in force can not be compatible.
And in the utility model, because it has been two key elements independently that crusher chamber has been taked the measure of " segmentation classification ", the ratio of reduction and the angle of engagement, that is to say, even the angle of jaw is arranged to zero degree (plumbness) even negative angle state, does not affect its ratio of reduction.So under the utility model technology, snap-in force and the ratio of reduction are in full accord, make the crushing performance of jaw crusher more perfect.
2. take this opportunity to realize the lamination crushing function of jaw crusher.
Under the utility model technology, supporting " large stroke " jaw motion feature has been realized the Cracking Mechanism of " lamination is broken " simultaneously.
The lamination fragmentation is to be equivalent to single fragmentation, single fragmentation be between two jaws be single material in fragmentation, be the jaw pressing materials; The lamination fragmentation is many materials to be arranged in fragmentation between two jaws, is the material pressing materials.
The 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 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;
It is broken that " large stroke " motion feature makes material produce enough laminations;
" large pilled-in selvedge " motion feature makes crusher chamber be issued to purpose in small, broken bits at the state in large gap.
Under Cracking Mechanism of Single Granule, granule just needs little pilled-in selvedge, and little pilled-in selvedge output is just low; And under the crusher reason, be under large pilled-in selvedge, to realize granule, effect is granule, large output.Like this, the crushing performance of jaw crusher significantly promotes.
As preferably, the tooth-shape structure that forms on the polylith jaw of the same plane of disruption 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, make large granular materials 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 lower end afterbody crusher chamber in the staged crusher chamber and be the sleeve configuration structure, the two jaw face lengths that form the sleeve configuration structure are 110~550mm, its angle angular range is-8 degree~+ 8 degree.
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;
2, angle character.The sleeve configuration crusher chamber is take the pilled-in selvedge state as standard, and its angle is-5~+ 5 degree, is conducive to discharge when choosing negative angle unobstructed, 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 operation cycle 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 " little 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 operation cycle 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, 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 polylith jaw that forms the same plane of disruption is two, three or four.
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, the polylith jaw that forms the same plane of disruption is that split is spliced or is formed by the connecting plate integrated connection.
The overall structure superiority is the device structure simplification, and it is convenient to change; The Split type structure stock utilization is high, and an each time replacing need replacing may wear to a fritter at the end and gets final product.
As preferably, the eccentric drive axis mechanism comprises an eccentric drive shaft, and moving jaw mechanism comprises a moving jaw, and bracket mechanism comprises a bracket;
The upper end of moving jaw is connected with eccentric drive shaft, and the lower end is connected with the front end of bracket; The rear end of bracket is connected on the frame.
The utility model be can be used for 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 the old machine, to transform than being easier to, manufacturing cost is relatively cheap.
As the alternative of such scheme, the eccentric drive axis mechanism comprises a pre-eccentric driving shaft and a rear eccentric drive shaft, and moving jaw mechanism comprises a front moving jaw and a rear moving jaw, and bracket mechanism comprises a front bracket and a rear bracket;
The upper end of front moving jaw is connected with the pre-eccentric driving shaft, and the 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 the lower end is connected with the front end of rear bracket; The rear end of rear bracket is connected on the frame.
Dual-crank-rocker mechanism is an important component part in the utility model, and its reinforcement effect provides necessary condition for super fine crushing; Its large stroke adjustment characteristic provides necessary assurance for the lamination fragmentation of little pilled-in selvedge, large stroke.
The required functional requirement of structure the utility model that the 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, and " subtracting stress effect " arranged, and its motion is take discharges material as major function, so the motion of moving jaw bottom is the stroke of discharging, rather than broken stroke.Be accompanied with some crushing functions, very little and loss is very large (because exist subtract power effect).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 jaw crusher in the prior art only with the limitation of a cover crank endplay device, the utility model uses the one in front and one in back combination of two cover crank endplay devices, eliminated the two conflicting drawback of prior art jaw crusher discharges material and broken work done, make a crusher have the effect of two-stage crushing, make broken material thinner, more even, fully saved again resource.
As the alternative of such scheme, the eccentric drive axis mechanism comprises a pre-eccentric driving shaft and a rear eccentric drive shaft; Moving jaw mechanism comprise the moving jaw of going forward, once before on the moving jaw, after moving jaw and rear moving jaw once; Bracket mechanism comprise the bracket of going forward, once before on the bracket, after bracket and once after bracket;
The go forward upper end of moving jaw is connected with the pre-eccentric driving shaft, and the lower end is connected with the front end of the bracket of going forward; The go forward rear end of bracket is connected with the lower end of upper rear moving jaw;
