Description
Technical field
The utility model relates to a kind of breaker roll device of disintegrating machine.
Background technology
According to the broken abstraction technique requirement of the oil shale of PetroChina Company Limited.'s Daqing oil field, design and make corresponding disintegrating machine.Oil shale mine water content 8-20%, water content is higher, and amplitude of variation is bigger, and granularity 0-300mm requires accounting for below 8% of discharging-material size≤1mm, and discharging-material size 〉=8mm accounts for below 5%, and 1mm-8mm should account for more than 88%.This disintegrating machine specification requirement height, design difficulty is big, and it is wide to relate to technological layer, and trial-produceing successfully of this product will be for the national energy industry provides a kind of rational in infrastructure, the reliable novel disintegrating apparatus of technology; Utilize the disintegrating machine of present existing various models that oil shale is carried out fragmentation, its effect is all undesirable.
(1) tests and the result with the HC disintegrating apparatus
Because of considering that the oil shale material size amplitude of variation of petroleum industry is very big, about general 200mm, have in addition reach 300mm, too big as its ratio of reduction of disposable fragmentation.Therefore selected the successful type-HC series one-part form energy efficient comminution machine that uses in cement industry and mine industry for use, this class disintegrating machine present stage is still one of irreplaceable capital equipment in the raw material preparation of domestic cement industry and the production of mine stone.In practical operation, this type is very desirable for the bulk precrushing of material.The center-top of this type has row's grid, though be a disintegrating machine, played coarse crushing and two kinds of effects in small, broken bits respectively, the material on grid reaches after the fineness by hammering, drain in the second layer crusher chamber, second layer crusher chamber is carried out fineness control with sieve plate.Although but sieve plate is adjusted to minimum 8mm, also can't stop passing through of tablet and needle-like material, transformed sieve plate shape (circular hole dress sieve plate) afterwards, produced the low excessively phenomenon of putty and output.
(2) with the dark chamber of PE jaw crusher result of the test
PEX series is dark chamber jaw crusher fine crusher, be characterized in simple in structure firm, adaptability is very strong, each rocks and mineral products that can broken 160--200MPa, but by test, the dark chamber of this class PEX series jaw crusher adapts to the hardness ratio of material, but the humidity reaction to material is responsive, moisture surpasses 10% will the adhesion putty, the moisture of test material oil shale surpasses sometimes can't be finished as the PEX jaw crusher 15% (general mineral material water content surpasses 15%, material will occur and dripping phenomenon occur in shattering process).When moisture content of material was big, material went out to stick together at discharge gate, and the material after the fragmentation can't be got rid of, even can stop up discharge gate, and output is very low.
(3) there is not stifled fine crusher result of the test with the PCXK reversible
After material enters disintegrating machine, being subjected to the high speed rotor rotated impacts, smash 70%-80% first, after the material of all the other 20%-30% obtains kinetic energy, rush at crushing shell at a high speed and be broken once more, bounce-back through crushing shell, once more by bullet to tup, so repeatedly, repeatedly broken in crusher chamber (comprise 70%-80% just mince material), meanwhile, material also is subjected to the mutual bump of storeroom and fragmentation.Product granularity control realizes by the adjustment in rotor and crushing shell gap.The material that is broken is discharged from discharge gate.
PCXK series disintegrating machine has been cancelled the sieve grate, controls discharging-material size by the gap of tup and crushing shell, can stop up sieve aperture thereby solved effectively when material is moisture when excessive, influences the problem of the operating efficiency of disintegrating machine.
PCXK series disintegrating machine is reversible, when tup and crushing shell wear and tear when excessive, makes the rotor reverse rotation, utilizes the another side work of tup and crushing shell, has prolonged service life effectively.
Every index of this experiment as: water content height, crushing material, the material that is broken clogging do not occur because of no sieve plate, because the high speed impact that the crusher rotor of the relative high speed rotation that PCXK series fine crusher is selected for use produces is carried out fragmentation, it is too in small, broken bits that the material that fragmentation goes out shows, crushing phenomenon was arranged, the fines proportion of discharging-material size below 1mm reaches 16%, is much higher than this experiment less than 8% require nearly one times.By adjusting the speed of crusher rotor, its fineness is difficult to control more afterwards, and is non-thick promptly thin, and the discharging ratio does not have rule to follow.
(4) experimental result of usefulness PG series kibbler roll
Two roll crushers and four-roller crusher adapt to the production requirement that 30mm is following and 20mm is following respectively, although experiment showed, that by traditional little discaling roll press and smooth roll press little discaling roll press crushing effect is better, tooth is little easily broken and be easy to wearing and tearing.A tooth causes the super coarse crushing of large tracts of land on every side if little tooth breaks, and make product defective, and the tooth plate replacement cycle is long, the fittings cost height.
The fragmentation of employing smooth roll, owing to be that the smooth roll material is easily sent out cunning, bulk materials can't be broken, the ratio of reduction of material is little, still have sheet material to occur in shattering process, and output is extremely low, because all materials are by the gap breaking between two rollers, work area is little, and output is very low.
Carry out axial built-up welding on smooth roll, manufacture difficulty is big, though solved the problem that material is easily sent out sliding, little when big in the time of can causing the gap between two rollers under the nonsynchronous situation of two roller built-up welding teeth, broken material occurred slightly and ultra-fine broken phenomenon.
To built-up welding, dimensional accuracy and shape are difficult to just protecting in the enterprising conduct of smooth roll, and manufacture difficulty is bigger, and broken working face increases to some extent than smooth roll, still seem narrow and small but opposite working is long-pending, and output improves not obvious.Because the bad assurance of radially built-up welding size, particle size after cracking is undesirable.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, reliable in function, production cost is low, production efficiency is high breaker roll device.
For solving the problems of the technologies described above, the technical solution of the utility model is: the breaker roll device, comprise at least two breaker rolls of working in coordination, described breaker roll comprises roll shaft, fixed cover is equipped with at least two roller sheets on the described roll shaft, and described roller sheet is formed broken roll body, and the roll surface of described broken roll body is a surface of revolution, the bus of described surface of revolution is a wave, and the crest of the described broken roll body that cooperatively interacts is inserted in the trough of another described broken roll body.
