Abstract
The invention relates to the field of mining machinery, and discloses a crusher rotor block and a crusher, aiming at overcoming the defects of such as easiness for material blocking, small crushing ratio, quick wear of wearing parts, and short service life in an old-fashioned rotor block. The rotor block consists of multiple sets of rotor disks, wherein each rotor disk is provided with an integrated web plate, and the web plate is provided with multiple sets of plate hammer supporting structures; each rotor disk is fixedly installed on the same shaft, and an angle is formed between two rotor disks. The crusher rotor block and the crusher disclosed by the invention has the advantages that the time when materials enter the crusher and impacted by a plate hammer in high-speed rotation is different, the crushed materials are thrown to a counter-attack plate at the other end of a crushing chamber along the tangential direction at a high speed and crushed again, and then rebounded from the counter-attack plate to the plate hammer, at the moment, the materials can be subjected to crossed impact and crushing between materials with materials crushed later, so that the crushing probability of the materials is increased, the crushing ratio is increased, the crushing efficiency is improved, and the yield is increased.
Description
The present invention relates to mechanical field, relate to a kind of mining machinery specifically, more specifically relate to a kind of disintegrating machine.
Background technology
Impact breaker utilizes the epitrochanterian bar of High Rotation Speed and counter beating hammer type disintegrator to utilize the epitrochanterian tup of High Rotation Speed, broken to the material generation high speed impact sent in disintegrating machine chamber, and make broken material tangentially to throw at a high speed the counterpunch board of the crusher chamber other end, again be broken, then to rebound bar from counterpunch board again, continue to repeat said process, due to material be subject to bar strike, with the impact of counterpunch board and material collision each other, material constantly produces crack, loose and arrive and pulverize.As can be seen from the shattering process of material, the fragmentation of bar to material plays an important role.Special instruction be that the mounting means of bar is vital especially.
There is following point in the rotor block of existing impact breaker and counter beating hammer type disintegrator:
Usually be all cartridge rotor dish on axle, rotor disk upper bearing plate hammered into shape and is installed point-blank, then bar is fixed.If Chinese Patent Application No. is application number: 00810055553.1, disclose openly a kind of such structure: " a kind of counter beating hammer type disintegrator; the crusher shell be made up of right baffle-plate, right baffle plate, fore shell, back cover, top cover and grate plate; be arranged on the line shaft on the right baffle-plate of crusher shell and right baffle plate is arranged on the multiple quartering hammers compositions on the line shaft of crusher shell inner chamber.The inwall of back cover is mounted with the liner plate that polylith is longitudinally arranged, fore shell is provided with charge door, the bottom of top cover is provided with the counterpunch board to lower process, quartering hammer and line shaft link fixing, and line shaft is mounted on crusher shell in relatively-stationary frame by bearing and bearing block.It is that a kind of grate plate is not yielding, the disintegrating machine that the consumption of liner plate and tup is little.”
All movable tup for what the rotor block of counter beating hammer type disintegrator was in the market installed.Broken poor effect, tup quick abrasion, general about 4 ~ 5 days, just needs replacing tup, changes frequent, causes raw-material great waste.Turn increase the labour intensity of workman, reduce output, add cost.And after making intersection bar into, bar is larger than the contact area of movable tup, broken probability is large, and broken ability by force, increases output.The utilization rate of bar is high, than movable tup height 3-4 doubly, decreases raw-material consumption and maintenance time, and not fragile, extends service life, reduces operation cost.
Be all movable tup and fixing castor bar for what the rotor block of counter beating hammer type disintegrator was in the market installed, tup quick abrasion, makes spacing between tup and discharge castor bar strengthen, causes discharging yield rate to reduce, and very easily putty.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of impact breaker and counter beating hammer type disintegrator rotor block.Rotor disk difference certain angle is arranged on axle, and on the other hand, for counter beating hammer type disintegrator, replace movable tup with bar, crushing effect is better.Meanwhile, below rotor block of the present invention, the castor bar of discharge gate is designed to hydraulic adjuster structure, is ensured the distance of castor bar and tup by hydraulic adjuster structure, can improve the yield rate that discharge velocity also can ensure discharging simultaneously effectively like this.Concrete scheme is as follows:
A kind of crusher rotor body, is made up of many group rotors dish, each rotor disk is arranged an overall web, described web is provided with many group bar supporting structures; Each rotor disk is fixedly mounted on same axis, differs certain angle between each rotor disk.
Between the bar of each rotor disk, best angle is 45 °.
Fixed by keyway mode between described supporting structure and bar.
Consistent for ensureing the crushing efficiency of disintegrating machine, according to the difference of material, the tup quantity that described every group rotor dish is installed is inconsistent.
The invention also discloses a kind of impact breaker or the counter beating hammer type disintegrator that use described rotor block, described disintegrating machine also comprises hydraulic pressure adjust structure, and described hydraulic pressure adjust structure is used for adjusting the castor bar of discharge gate below described rotor block and the spacing of tup.
Described hydraulic pressure adjust structure is: described castor bar is combined into one by frame; The piston rod of the hydraulic cylinder of described frame and hydraulic pressure adjust structure is fixed.
Advantage of the present invention is: a rotor block is made up of array rotor disk, each rotor disk devises the web of many group supporting bars, and as a whole.Each rotor disk is arranged on same axis and differs certain angle, and the installation of such bar is not elongated one, but becomes pieces.The spatial dimension of bar and counterpunch board is different, and when rotor high-speed rotates, material easily passes through, and solves the problem of easy putty.Material is to enter the time of being impacted by High Rotation Speed bar in disintegrating machine different, have successively, broken material tangentially to throw at a high speed the counterpunch board of the crusher chamber other end, is broken again, then to rebound bar from counterpunch board again, at this moment, can and the material of rear fragmentation carry out intersecting between material with material and clash into fragmentation, increase the disintegrating machine meeting of material, the ratio of reduction increased, crushing efficiency improves, and adds output.Meanwhile, after bar is designed to several piece, decrease resistance during running, not fragile; Alleviate weight, it is convenient to change, and significantly reduces the labour intensity of workman.For counter beating hammer type disintegrator, with bar band for movable tup.Bar is larger than the contact area of tup, and broken probability is large, and broken ability is strong, increases output.The utilization rate of bar is high, than tup height 3-4 doubly, decreases maintenance time, less than movable tup frictional force, extends service life, decreases the consumption of consumable accessory, improve production capacity.Meanwhile, the castor bar of discharge gate below rotor block is designed to hydraulic adjuster structure, the yield rate that discharge velocity also can ensure discharging simultaneously effectively can be improved.
