Description
Technical field:
The present invention relates to a kind of horizontal revolving drum powder and prepare the flash device that equipment is used, especially for the branch storehouse of large continuous dry method and wet method planetary ball mill and the conical surface sieve flash device of discharging.
Background technology:
In the ball mill, pellet mixes, and material must be separated with ball during discharging continuously.Conventional method adopts the end face sieve plate, allows material by sieve aperture, stops ball to pass through.There is shortcoming in this method---be difficult to keep the grinding operating mode of being scheduled to.
Grinding operating mode in the mill tube is influenced by material ball ratio.Material ball ratio is too little, and ball and ball direct collision can take place, and material ball ratio is too big, and material produces excessive damping action to the motion of ball, has reduced the active force to powder, and both of these case all reduces mill efficiency.
Under the quiescent conditions, people can be in desirable ratio, and pellet is packed in the mill storehouse.After the running, charging constantly and discharging have produced the dynamic equilibrium problem.
During dynamic equilibrium, inlet amount must equal load.The former is by the output decision, and the latter is then determined by area by grid.The designer is difficult to accurately calculate required area.If less than normal, then inlet amount is greater than load, and error constantly accumulates, and material level is long-pending more high more in the mill storehouse, possibility " mill rises " when serious, on the contrary then fewer and feweri, possibility when serious " empty mill "
The present invention---conical surface flash device can be kept predetermined best material ball ratio under current intelligence.After the flash aperture of conical surface sieve flash device is determined, surpass the material in flash hole, from enough big grid, discharge outside the storehouse fast, the too high situation of charge level can not take place; Otherwise, can charge level not low excessively yet, there is not flow pass because be lower than the material in flash hole.
The grid of conical surface sieve needn't accurate Calculation its by area, as long as enough greatly.
Particularly suitable of the present invention is in the discharging structure design of large continuous planetary ball mill.Because planetary ball mill grinding speed is higher, and the mill storage capacity is less relatively, and the accumulated error in the short time will reach the degree that can not allow.Therefore, can not adopt the end face sieve plate.
Summary of the invention:
The invention provides a kind of conical surface sieve flash device that material overflows that helps.
The present invention adopts following technical scheme:
A kind of conical surface sieve flash device, comprise annular plate 2, on annular plate 2, be provided with tapered cap 1 and cylindrical shell 3, tapered cap 1 is positioned at cylindrical shell 3, be provided with grid on tapered cap 1, the endoporus 9 of annular plate 2 is positioned at a side of tapered cap 1, is positioned at the opposite side of tapered cap 1 by annular plate 2 and tube 3 storehouses that constitute 11, the endoporus 9 of described annular plate 2 is a charging aperture, and described grid is a discharging opening.
Compared with prior art, the present invention has following advantage:
1) the planetary ball mill material ball ratio is extremely important to grinding quality and efficient, especially can not too much cause " mill rises " because of powder, adopts the present invention can realize ball mill branch storehouse grinding well.The present invention can also be used for drawing mechanism, makes the material ball ratio in the tube constant substantially.
2) rely on gravity or centrifugal force flash.If adopt thrust or " wind is swept ", not only waste energy, and may so not only the barrel wearing and tearing be increased the weight of because of the smooth material storing excess that does not make in the mill tube of discharging because of the pressure in the mill tube increases, more likely make breakneck things such as cylindrical shell breaks.And material overflows by the sieve aperture on the tapered cap in the present invention, can be when overflowing by radially overflowing rather than traditional axially overflowing, so can be after material enters tapered cap by gravity from radially overflowing, perhaps the rotation with cylindrical shell relies on centrifugal force to overflow, and does not need to add an axial thrust specially to material.
3) have " automatically " function, promptly can spill into another storehouse automatically,, rather than determine by the size of thrust because when material overflows the internal diameter decision by annular plate as long as the material in a certain storehouse reaches certain height.Have the quick adjustment function simultaneously, when the material in a certain storehouse increased suddenly, material can spill into another storehouse fast by enough big sieve aperture; When the material in a certain storehouse reduced suddenly, flash device can keep the material in this storehouse, does not allow and overflows, and helps keeping material ball ratio, avoids empty mill; In having the planetary ball mill of many mill tubes, because material ball ratio is constant substantially, unlikely causing laid particular stress on imbalance state when slightly uneven as if each mill tube inlet amount.
Description of drawings:
Fig. 1 is a kind of structural representation of the present invention.Wherein 1 is conulite, and semi-cone angle φ=10 ° ~ 30 ° are different with different powders, and enough big sieve aperture is arranged on the conical surface, different with different powders, and the material stock amount in the tube is by the diameter decision of the big end of bullet.2 is annular plate, welds together with conulite, and outer shroud is connected with the tube inwall.
Fig. 2 is used for the discharging schematic diagram for conical surface sieve flash device, and wherein Fig. 2 A is the discharge end cutaway view, and Fig. 2 B is a discharge end A-A cutaway view.Along with material constantly adds the grinding storehouse, material can reach certain height in the grinding storehouse, thereby enter tapered cap 6, fall into deposit storehouse 5 by grid, enter low level interval in the quick feeder dividing plate via the annular gap between cylinder internal diameter and back side plectane, by feeder material is sent then.The present invention can keep the height of an interior material automatically, prevents to expect that too many and " mill rises " prevents to expect very little and " empty mill " simultaneously.
