Abstract
The utility model discloses a superfine crushing pair formed by cavity-shaped self-grinding. The superfine crushing pair comprises a pair of jaw plates which are opposite to each other to form the crushing pair, wherein both jaw plates are flat plates and are provided with drainage holes which are arranged at equal interval in the transverse direction of the jaw plates; each single hole in the drainage holes is in a long flat structure which is long in the transverse direction and short in the vertical direction; and each single hole is wide in the middle and narrow on the two edges in the transverse direction of the single hole. The space between two adjacent drainage holes in the drainage holes is zero; and each single hole on two adjacent drainage holes is arranged vertically in a staggering way. By applying a trapezoidal unbalanced wear principle of the long flat hole, the cavity-shaped self-grinding is realized, and the aim of superfine crushing is fulfilled. When the central part of the hole is worn before the two edges of the hole, a tooth valley-shaped part is formed, and tooth peak-shaped parts are formed on the two edges of the hole. Thus, the crushing pair is changed from the flat plate shape into the toothed plate shape, so that the crushing efficiency is greatly improved.
Description
Technical field
The utility model relates to the jaw crusher field, and what a kind of chamber shape autogenous grinding of more specifically saying so formed is ultra-fine broken broken secondary.
Background technology
Jaw crusher claims that also jaw is broken, is with the longest history, one of most popular disintegrating apparatus.
Jaw is broken to be typical " thick broken " equipment.
Here thick broken two contents that have: one, jaw is broken is not accurate equipment; It is all convenient to that is to say its (machine tool just can be competent at) simple in structure, easy to manufacture, use and keep in repair; And the operating cost that jaw is broken 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 welcome always so far; Two, the broken material of being up to of jaw very thick (breaking fines is difficult to), this is relevant with the broken breaking cavity structure of jaw, no matter and how chamber shape is innovated and is improved, all can have foozle, alignment error and use error, so jaw breaks the very difficult fines of beating.
As everyone knows, the breaking cavity under the prior art all is that just processing is definite during fabrication, and the error in making, install, using has directly influenced the precision (being the fineness of dnockout) of breaking cavity.
The applicant's intention is: design a kind of new broken auxiliary structure; The breaking cavity of its formation needn't be made in factory to form; But in use wear into naturally, this breaking cavity of wearing into naturally has the function that autogenous grinding is reviewed one's lessons by oneself, and can not have foozle; And the error component in installing and using also can be eliminated in autogenous grinding naturally.Realize a kind of high-precision broken pair, jaw is broken also can reach ultra-fine broken purpose.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective, the ultra-fine broken broken pair that provides a kind of chamber shape autogenous grinding simple in structure, that cost is low to form.
In order to reach above purpose; The utility model is realized through following technical scheme: what the shape autogenous grinding of a kind of chamber formed is ultra-fine broken broken secondary; Comprise that a pair of face-off forms broken secondary jaw; It is characterized in that said jaw is flat board, and be provided with the round of laterally equidistantly arranging along it on it.
Each single hole in the said round is the perpendicular short long and flat structure of growing crosswise, and each single hole wide both sides in the middle of it is in a lateral direction are narrow.
The spacing of adjacent two rounds is zero in the said round, the upper and lower interlaced arrangement of each single hole on adjacent two rounds.
Each single hole shape in the said round is rhombus or is ellipse.
Architectural feature: 1. broken secondary by two dull and stereotyped compositions.2. flat board is provided with round; Each single hole in the round is horizontal length, vertical short and middle shape wide, that progressively narrow down to both sides; Upper and lower staggered and left and right two sidelines of each single hole on adjacent two rounds are on same center line; Each single hole in each row's round equidistantly evenly distributes; 3. two dull and stereotyped round center line interlaced arrangement.
Core technology: by center, the two jaw holes interlaced arrangement in narrow long flat shape hole, wide both sides, centre.Use the unbalanced wearing and tearing principle of gradient in long flat shape hole, realize that chamber shape autogenous grinding forms, thereby reach ultra-fine broken purpose.
The mechanism of reviewing one's lessons by oneself chamber shape is following:
Because broken two secondary jaws are center, hole interlaced arrangement in the utility model; Promptly be that the center, hole is to the limit, hole; And the hole is that the middle part is wide, and both sides are narrow, (also is that the middle part, hole is easy to wear so in broken mill, can form gradient uneven wear mechanism; The both sides, hole are not easy to wear), therefore in broken mill, formed chamber shape naturally.Break formation in the mill because chamber shape is a nature, its chamber shape accuracy of mesh high (not having in the broken pair under the prior art because of the error of making, installation, maintenance brings) is so the very suitable fines of beating.
In broken mill, it also has the effect of self-balancing mechanism.
In the broken pair of the utility model, though it is fast to be the center, hole than the wearing and tearing of hole limit, it can not wear and tear down always fast, until in the centre, hole at first by broken worn out.When wear and tear prior to the both sides, hole in the centre, hole, just formed a tooth paddy shape, the both sides, hole have then formed tooth peak shape.At this moment broken pair just changes the tooth plate shape into by tabular, and crushing efficiency is greatly improved thus.
The rate of wear at above-mentioned tooth paddy place can be progressively slack-off (because after the both sides, hole have formed tooth peak shape; The peak-to-peak distance of tooth is a definite value; When the tooth paddy degree of depth during near tooth paddy width; Tooth paddy position will be fewer and feweri by the chance of broken mill, just do not have brokenly chance-both no longer continuation wearing and tearing of mill when reaching certain depth again again).And at this moment the tooth peak also continues wearing and tearing at broken mill bulk material (material that surpasses facewidth degree) to the tooth peak; When the tooth peak has ground to a certain degree; Tooth paddy has been by having shoaled, and tooth paddy not only begins to participate in brokenly mill-promptly but also wearing and tearing has been arranged ... Go round and begin again, make tooth peak and the tooth paddy can be in the broken mill process of nature; All the time be equilibrated at certain certain value, also can remain a metastable chamber shape.This has just reached and in the nature process of fragmentation, has formed accurate crusher chamber naturally, reaches thin broken purpose.
Naturally the chamber shape that forms is also closely related with material, and material is hard, and chamber shape is dark, otherwise shallow; Material particles is little, and chamber shape is also dark, otherwise shallow.
The applicant has declared name and has been called " a kind of multi-functional broken pair of reviewing one's lessons by oneself profile of tooth " patent hereinafter to be referred as " reviewing one's lessons by oneself profile of tooth " (patent No. is 2011200884316.5).
Both are in difference:
1. structure is different: " reviewing one's lessons by oneself profile of tooth " is to process the odontoid structure in advance, in broken mill, keeps profile of tooth through reviewing one's lessons by oneself mechanism then;
And the utility model is that profile of tooth is not set in advance, is dull and stereotyped, in broken mill, just forms chamber shape, makes chamber shape engagement accurate.
2. mechanism is different: " reviewing one's lessons by oneself profile of tooth " is careless about chamber shape, as long as tooth paddy can just can with the wearing and tearing synchronously of tooth peak along with broken.How unimportant shape for mill is entered is, and therefore " reviewing one's lessons by oneself profile of tooth " to the round shape does not all have special demands with arranging.
The utility model is particular about chamber shape, has only chamber shape engagement precision just can reach purpose in small, broken bits.Therefore, the utility model is worthy of careful study to the round shape, requires the long and flat hole, and single hole is middle wide, and both sides are narrow, and the hole back gauge of adjacent two rounds is zero, forms the unbalanced wearing and tearing of gradient, makes it form the chamber type
3. function is different: the purpose of " reviewing one's lessons by oneself profile of tooth " is to make profile of tooth along with broken mill process remains intact, to reach the superior Cracking Mechanism of odontoid
And the purpose of the utility model be " review one's lessons by oneself chamber shape ", along with broken mill process forms accurate chamber type, to reach brokenly the purpose of fines.
The applicant has also declared name and has been called " a kind of anodontia tooth plate is broken secondary ", hereinafter to be referred as the patent of " anodontia tooth plate " (patent No. is 201120145194.6).
Both are in difference:
1. structure is different: " anodontia tooth plate " is the hole of " netted " character, and the limit of promptly forming the hole is wide " rib strip shaped structure ";
And the utility model is the hole of " how much shape " character, and its limit of forming the hole is not wide, also irregular " block structure ".
2. mechanism is different: " anodontia tooth plate " purpose is " Cracking Mechanism ", is careless about chamber shape.Be to produce superior Cracking Mechanisms such as " split broken, folding is broken and crowded broken " with wide rib strip shaped structure.How unimportant shape for grinding after entering is, and therefore " anodontia tooth plate " do not have special demands to the shape and the arrangement mode in hole;
The utility model is particular about chamber shape, has only chamber shape engagement precision just can reach ultra-fine broken purpose.Therefore, the utility model is worthy of careful study to the shape and the arrangement mode of round: require the centre in hole wide, both sides are narrow, and distance is zero between the two row holes, could form the unbalanced wearing and tearing of gradient, and makes the accurate chamber type of its formation smooth and continuous.
3. function is different: the purpose of " anodontia tooth plate " is to realize the superior Cracking Mechanism of " split broken, folding is broken and crowded broken "
And the purpose of the utility model is " reviewing one's lessons by oneself chamber shape ", promptly along with broken mill process forms accurate chamber type, and can eliminate the error that causes because of in manufacturing, installation and the use voluntarily, to reach ultra-fine broken purpose.
To the relation between " reviewing one's lessons by oneself profile of tooth ", " anodontia tooth plate " and " reviewing one's lessons by oneself the chamber type " three of the applicant's innovation (the development experience that combines jaw), can also do further combing analysis:
In the developing history of jaw, the tooth-shape structure design is a big technological progress.Tooth-shape structure is much more superior than solid slab construction, so the broken tooth-shape structure formula jaw (jaw crusher is just come in a group with the dentation jaw from being born) of selecting for use basically of jaw.But superior tooth-shape structure design its function is in practice brought into play limitedly, exactly because along with broken process " tooth " shape rapidly disappears, and the decay of the function of tooth-shape structure.
So, the applicant's innovative design " reviewing one's lessons by oneself profile of tooth " jaw (applying date: 2011.3.28), make jaw have the function of the profile of tooth reviewed one's lessons by oneself, profile of tooth consistently, function is also remained the same from beginning to end, and makes that the Cracking Mechanism of tooth-shape structure is fully played.
Under above basis; The applicant again further innovative design " anodontia the tooth plate " (applying date: 2011.5.1); " anodontia tooth plate " has all functions in the profile of tooth reviewed one's lessons by oneself; " but anodontia tooth plate " also has sufficient shearing-crushing function mechanism in addition, and " reviewing one's lessons by oneself profile of tooth " though the shearing-crushing function is also arranged, insufficient; Because " review one's lessons by oneself profile of tooth " and also have exist (tooth paddy place has place, shearing-crushing mechanism tooth peak then not have) of profile of tooth, the broken function that " anodontia tooth plate " has big snap-in force is also stronger.
Because the anti-shearing stress-strength ratio compressive stress intensity of material is much lower usually, more produce effect than being in the crushing fragmentation so be in the fragmentation of shearing under the mechanism.
" anodontia tooth plate " promoted the Cracking Mechanism of jaw crusher, makes it more superior.Therefore, " anodontia tooth plate " on the basis of " reviewing one's lessons by oneself profile of tooth ", technology has been advanced major step again.
" it is ultra-fine broken broken secondary that the type autogenous grinding of a kind of chamber forms " of the utility model is hereinafter to be referred as " chamber type autogenous grinding ".It not only reviews one's lessons by oneself " profile of tooth ", and wears into " chamber type " (triangular chamber or waveform chamber) voluntarily;
Its superiority is: 1. " chamber type autogenous grinding " have eliminate voluntarily because of make, install and use in the error brought, make crusher chamber remain accuracy, realize ultra-fine broken purpose; " chamber type autogenous grinding " have " little tooth " Cracking Mechanism and " canine tooth " Cracking Mechanism, little tooth Cracking Mechanism is brought by " hole ", and the canine tooth Cracking Mechanism to be autogenous grinding form " chamber type " brings.In broken secondary, the bottom, little material produces " split, roll over and squeeze " Cracking Mechanism by pore structure, this is " little tooth " Cracking Mechanism (each aperture all is little tooth); This situation is identical with " anodontia tooth plate "; In broken secondary, top; Big material produces " split, roll over and squeeze " Cracking Mechanism by " chamber type " structure; This be " anodontia tooth plate " can't be obtained because " anodontia tooth plate " broken secondary broken mill result is tabular all the time, and corrugated chamber type can not appear.
At, the utility model is shifted the jaw technology onto very perfectly height.
The utility model also has following beneficial effect except above function:
1. prolong the service life of jaw.In the tooth plate manufacture process, need carry out quenching heat treatment, promptly to red-hot tooth plate immersion water, cool off fast, to reach the purpose of quench hardening heating.The utility model is provided with many containing grooves on jaw, increased the contact area of jaw and water greatly, has improved the quenching degree in the quenching technical, thereby has improved the hardness (wearability) of jaw, prolongs its service life.
2. the utility model is frustrated cutter and scissors just as a secondary well combination by being the hole group structure, material with frustrate, the mode of cutting is broken.Usually the anti-shearing stress-strength ratio compressive stress intensity of material is much lower, more produces effect than being in the crushing fragmentation so be in the fragmentation of shearing under the mechanism.Then make jaw have big snap-in force function.This big snap-in force function is very favourable to fragmentation, is embodied as: 1. on " V " crusher chamber, grab and sting the enhancing of (eating into) material ability; 2. in shattering process,,, promoted the crushing performance of disintegrating machine Yi Bian advance toward the discharge direction along with broken on one side material is broken.
3. because the broken pair of the utility model is the parallel jaws in both sides, can exchange usefulness in positive and negative both sides, add that two is interchangeable again up and down, more reasonable with material.
As preferably, each the single hole shape in the said round is rectangle, divides between adjacent two rounds to offer intervallum.This preferred version is fit to not be broken very thin material.Have only the strong characteristics of shearing-crushing function.
As preferably, the longitudinal cross-section of jaw is two folded structures.Two folded structures promptly are provided with one section parallel chamber in V-arrangement crusher chamber lower end, play ultra-fine broken purpose.
