Background technology
Quench according to the oil shale fragmentation of PetroChina Company Limited.'s Daqing oil field and to get specification requirement, design and make corresponding disintegrating machine.The oil shale mine water content is higher and amplitude of variation is bigger, general water content 8-20%, sillar granularity 0-300mm, require discharging-material size≤1mm account for below 8%, discharging-material size 〉=8mm account for below 5%, granularity 1mm-8mm should account for more than 88%; Big to the requirement height of disintegrating machine, design difficulty as can be seen by above-mentioned specification requirement, to relate to technological layer wide, this product trial-produce to the national energy industry provides a kind of rational in infrastructure the reliable novel disintegrating apparatus of technology successfully.
Existing disintegrating apparatus comprises, chamber jaw crusher, PCXK reversible do not have stifled fine crusher, PG series kibbler roll deeply, utilize the disintegrating machine of these present existing various models that oil shale is carried out fragmentation, all undesirable as its effect of comparative example of the present invention:
1, the test and the result of the existing HC hammer crushing equipment of my company
Petroleum industry oil shale material size amplitude of variation is very big, about general 200mm, even reaches 300mm, so the words ratio of reduction of disposable fragmentation is too big.So successful type-HC series one-part form energy efficient comminution machine of selecting for use my company to use at cement industry and mine industry.
In practical operation, find that this type is very desirable for the bulk precrushing of material.As Figure 1-3,1---tup, 2---grid, 3---sieve plate, the center-top of this type have row's grid 2, after the material on grid 2 impacts fineness by tup 1, drain in the second layer crusher chamber, second layer crusher chamber is carried out further fineness control with sieve plate 3.
Although the result adjusts to minimum 8mm to sieve plate, tablet and needle-like material 5 still can pass through sieve aperture 4, transform sieve aperture 4 afterwards and are shaped as circular hole, eventually cross the low the failure of an experiment of announcing because of putty and output.
2, the existing dark chamber of PEX jaw crusher test and result
The characteristics of the dark chamber of PEX series jaw crusher fine crusher be simple in structure firmly, adaptability is very strong, each rocks and mineral products that can broken 160--200MPa, but by test, this class disintegrating machine is responsive to the humidity reaction of material, moisture surpasses 10% will the adhesion putty, the moisture of test material oil shale surpassed for 15% (general mineral material water content surpasses 15%, material will occur and dripping phenomenon occur in shattering process) sometimes.
As shown in Figure 4, this disintegrating machine comprises 1---frame, and 2---fixed jaw, 3---sewing jaw, 4---moving jaw, 5---eccentric shaft, 6---bracket, 7---adjust seat.
As shown in the figure, 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, existing PCXK reversible does not have stifled fine crusher test and result
As shown in Figure 5, this fine crusher comprises 1---the crushing shell adjusting device, and 2---crushing shell, 3---main shaft, 4---tup, 5---body, 6---the crushing shell bracing frame, 7---cover.
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 2 at a high speed and be broken once more, bounce-back through crushing shell 2, once more by bullet to tup 4, 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 that by the adjustment in rotor 3,4 and crushing shell 2 gaps 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, thereby has solved effectively when the moisture problem that can stop up sieve aperture when excessive, influence the operating efficiency of disintegrating machine of material.
Result of the test shows that it is too in small, broken bits that the material that fragmentation goes out shows, and crushing phenomenon was arranged, and the fines proportion of discharging-material size below 1mm reaches 16%, is much higher than this experiment less than 8% requirement.By adjusting the speed of crusher rotor, its fineness is thrown away and is difficult to control afterwards, and is non-thick promptly thin, and the discharging ratio does not have rule to follow.
4, the experiment of kibbler roll and result
PG series two roll crushers and four-roller crusher that company produces according to the power system customer requirements adapt to the production requirement of the following and following granularity of 20mm of 30mm respectively, and this little discaling roll press crushing effect is better, but tooth is little easily broken and be easy to wearing and tearing.A tooth 1 (Fig. 6) causes the super coarse crushing of large tracts of land on every side if little tooth breaks, and makes product defective, and tooth plate is changed operation difficulty, fittings cost height.
As shown in Figure 7, use bachelor's fragmentation instead, owing to be that bachelor's material is easily sent out cunning, bulk materials can't be broken, and the ratio of reduction of material is little, still have sheet material (mark 1 among the figure) to occur in the shattering process kind, and output is extremely low.
As shown in Figure 8, to the axial built-up welding of breaker roll, form broken projection 1, this built-up welding manufacture difficulty is big, easily sends out situation sliding though solved material, and two roller built-up welding teeth are not easy synchronously, at this moment little when big in the time of can causing the gap between two rollers, broken material occurred slightly and ultra-fine broken phenomenon.
As shown in Figure 9, to radially built-up welding of breaker roll, form broken projection 1, this built-up welding dimensional accuracy and shape are difficult to just protecting, manufacture difficulty is bigger, and broken working face increases to some extent than the bachelor, still seems narrow and small but opposite working is long-pending, because the bad assurance of radially built-up welding size, particle size after cracking is inhomogeneous, undesirable.
