Abstract
The invention discloses an impact crusher equipped with rolling device impelling heads, which comprises a plurality of rolling device impelling heads, a material-distribution disc, an impeller main shaft, an impeller, a frame, a material counterattack plate, a feed hopper, and a feed barrel. A plurality of channel ports are disposed at the profile edge of the impeller. The invention is characterized in that: a plurality of rolling device impelling heads are disposed at the channel ports; the rolling device is cylindrical, and comprises a support shaft, bearings, covers, and wear-resistant sleeves. When broken materials are impelled out from a jet orifice under the centrifugal force of high-speed rotation, the material and the wear-resistant sleeves of the rolling device impelling heads synchronously move with a same linear velocity, and no sliding friction, that is, no wearing is generated. The most significant effect of the invention is that the service life of the impelling head is greatly improved, and thus bottlenecks which puzzle the application and development of impact crushers for a long time are broken through. The invention is simple in structure, easy to manufacture, low in cost, and convenient for old product reconstruction into the invention.
Description
Technical field
The present invention relates to the mining machinery field, relate in particular to a kind of impact crusher that tourelle impelling head is housed.
Background technology
Impact crusher is material friction and broken (stone-crash-stone) between fragmentation and the material voluntarily each other that utilizes high speed rotating, be adapted to ultrahard, in the coarse crushing and the operation in small, broken bits of hard and abrasion material.Be a kind of efficiency crushing equipment of energy-conservation, material-saving.
Material is material inlet from the top; Get in the impeller that rotates at a high speed through barrel, material pours crusher chamber with 40-100m/s speed under the action of the centrifugal at last; Acutely bump against with suspended material of before having dished out and material counterpunch board; Material after the bounce-back collides with the material of from impeller, launching again once more, repeatedly repeats, and the material that loses kinetic energy is at last discharged from crusher chamber under the gravity effect.
Impeller is as the core component in the impact crusher, and three outlets (also having more than two and three) are established at said impeller edge, and an impelling head (also claiming a material casting blade, bistrique) that studs with carbide alloy all is equipped with in each exit.In the actual use of impact crusher, the impelling head wearing and tearing on the high speed rotating impeller are very big, and this is that impact crusher is used and developing one big bottleneck.
In order to solve big this problem of impelling head wearing and tearing on the impeller, people adopt following mode usually:
One, reduce wheel speed, with reduction wearing and tearing dynamics, but this is opposite with operating efficiency.In order to improve crushing effect, not reduction of speed in the middle of the reality, but speed-raising.
Two, improve impelling head material hardness; Along with the material technology progress, have very great development, but this respect space was very little in recent years; Hard again alloy knife is tool sharpening on the emery wheel mill all; Strong wearing and tearing are inevitable, and the stream of mineral under the 40-100m/s linear velocity is being ground " impelling head " just like a big emery wheel.
Three, about the impelling head, be technological personage's in the industry public relations project always, try hard to break through in all its bearings; For example the patent No. " 200820157904.5 " patent name is " the external force structure that is used for standing crusher ", to quick abrasion, two slow situation up and down in the middle of the impelling head; Proposition is divided into three with cutter head (impelling head); Promptly be divided into three sections, wear and tear one that is in the middle of can only changing when changing like this, prolong the cutter head purpose of service time thereby reach.This scheme is good, but effective income is very little.
As long as between impelling head and the high speed material is to be in the sliding friction, high wearing and tearing are exactly inevitable.All effort and effects that prolong the impelling life-span all are an utterly inadequate amount, general machine components service life with the moon, year calculate, the impelling head is calculating (being generally more than 100 hour) by the hour then.In a word, this type principle of impact crusher is advanced, manufacturing is simple, result of use is good, but just is stuck on this bottleneck of this impelling life-span.
Summary of the invention
The deficiency of prior art is exactly to be that impelling head and material always are in the sliding friction, in the face of material at a high speed, is grinding alloy knife just as emery wheel; High wearing and tearing are inevitable, and the object of the invention has just provided a kind of impact crusher that tourelle impelling head is housed of novel structure, is to replace edge alloy knife material casting head of the prior art with a kind of tourelle impelling head; Promptly substituted sliding friction with rolling friction; The high speed material is close to and is being driven a tourelle impelling wear sleeve and rotate in impelling, and linear velocity is synchronous between material and the wearproof roller; Do not rub; Just there have not been wearing and tearing (actual impelling head has inertia lag and frictional force when rotating, and a certain amount of sliding friction and wearing and tearing are also arranged, and much less is wanted in the slippage that just is equivalent to alloy impelling head) yet
The present invention adopts following technical scheme to realize.The impact crusher that tourelle impelling head is housed according to the present invention's proposition; Comprise a plurality of tourelle impelling heads, impeller, material separating disc, impeller spindle, frame, material counterpunch board, feed hopper and give barrel; The contour edge of said impeller is provided with a plurality of runner mouths; Said impeller is provided with cornice sheathing and wainscot sheathing, and the place is provided with tourelle impelling head at said runner mouth.
The aforesaid impact crusher that tourelle impelling head is housed; Wherein said tourelle impelling head is a cylindrical structural; And the centre is provided with a back shaft; The two ends of said back shaft two bearings of corresponding respectively connection and break-through are in said two bearings, and said back shaft and said two bearings are coated and fixed by wear sleeve, and the two ends of said wear sleeve are provided with two stifles.
The aforesaid impact crusher that tourelle impelling head is housed, the cornice sheathing of wherein said impeller and wainscot sheathing have the hole that is used to install tourelle impelling head at impelling mouth place.
The aforesaid impact crusher that tourelle impelling head is housed, wherein said tourelle impelling head are fixedly connected on through back shaft in the hole at impelling mouth place between cornice sheathing and the wainscot sheathing of impeller.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.
