As it is shown in figure 5, angle liner plate 35 be higher level's feed bin shell liner, subordinate's feed bin shell liner respectively with grate plate I 33, the intersection region of blind plate I 34.Angle liner plate 35 is identical with the thickness of grate plate I 33 and blind plate I 34, and height is the most identical with the flange 21 of shell liner, is just sealed by shell liner, grate plate I 33 and blind plate I 34, is worn and torn by material hardly, need not be able to change with long-play.Do not have when being individually replaced shell liner, grate plate I 33 or blind plate I 34 and interfere impact.
As shown in Figure 6, the elongated hole on support I 32 is that material is entered the passage of center ring I 31 by support I 32.Dividing plate 311 is separated into two toroidal cavities by internal for center ring I 31, is provided with stock guide I 312 in the cavity of higher level's feed bin side.After material entrance center ring I 31 under the effect of stock guide I 312, run through the notch on dividing plate I 311 and enter the toroidal cavity of subordinate's feed bin side.The most automatically subordinate's feed bin is overflowed into after toroidal cavity accumulation slight amount.Being provided with flashboard I 313 on the material path I 314 of dividing plate I 311, the folding size controlling flashboard I 313 can regulate the material speed by middle partition device for barn, facilitates user according to different Operating condition adjustment yield.
As it is shown in fig. 7, material wind separate type discharge bin is by angle liner plate 35, grate plate II 43, support II 42 and center ring II 41 composition.The structure of angle liner plate 35 is identical with the angle lining plate structure of the middle compartment of material wind separate type, for the grate plate II 43 of shell liner with material wind separate type discharge bin being kept apart, installs or changes shell liner and will not interfere with grate plate.Grate plate II 43 uses wear-resisting steel plate blanking, and seam of combing is shaped by machining, and last heat treatment forms.The profile comparison rule of grate plate is attractive in appearance, seam size uniform of combing, marshalling.Support II 42 forms for Plate Welding, uses lifting effect good curve lifting blade, it is possible to quickly sent in center ring II 41 by the elongated hole on support II 42 top by material.Center ring II 41 is Plate Welding part, for stream being separated with air-flow.
As shown in Figure 8, center ring II 41 structure of material wind separate type discharge bin 4 is similar to the center ring I of middle compartment, material wind separation principle is identical, center ring II inner chamber is divided into two toroidal cavities by dividing plate II 44, it is provided with stock guide II 45 in the cavity of higher level's feed bin side, stock guide II is for guiding material rapidly to the cavity going out to grind side, the material path II 47 of dividing plate II 44 is provided with flashboard II 46, the folding size controlling flashboard flashboard II 46 can regulate the material speed by middle partition device for barn, facilitates user according to different Operating condition adjustment yield.Difference is that material wind separate type discharge bin 4 support directly against cylinder web, stressing conditions is better than middle compartment, and go out to grind side and there is no steel ball, therefore eliminate on center ring II 41 near going out to grind the baffle plate of side so that material can freely overflow into discharge pipe grinding machine in transmission adapter after entering out the toroidal cavity of mill side by stock guide.
As it is shown in figure 9, a storehouse feed bin shell liner is to have made Optimal improvements on the basis of conventional ladder lining board.The improving performance of conventional ladder lining board is preferable, but milling area is less.And current most grinding system all roll squeezers in tube mill former configuration so that the feed size of tube mill is less, the grinding effect of a storehouse feed bin shell liner needs to strengthen.The present invention adds hoop groove on the lifting face of conventional ladder lining board, increases effective milling area of one-level feed bin in the case of the lifting force keeping ladder lining board does not subtracts.
As shown in Figure 10, two grades of feed bin shell liners use small ripple glaze lining board of globe.Through the crushing grinding of one-level feed bin, when material enters two grades of feed bins, particle size is less, and therefore the shell liner of two grades of feed bins is mainly used to grind.The milling area of small ripple glaze lining board of globe is relatively big, and grinding effect is good.
Shell liner uses one-level feed bin storehouse groove step liner plate to add the combining form of two grades of feed bin small ripple glaze lining board of globe, is simultaneous for different grinding process and adds some circle activation lining boards to control material flow in grinding at two grades of feed bins.The adaptability of this shell liner combining form is good, can the bigger material of crushing grinding Feed size, the material that Feed size is less can be successfully managed again.
As shown in figure 11, conventional spreader groove structure is improved to low-pressure tank structure by the low pressure lubricating system of slide shoe bearing.Low-pressure tank structure is made up of oil-in 51, low-pressure tank 52 and Oil Guide face 53.Low pressure oil is transported to hold in the palm at the oil-in 51 of watt side from dilute oil lubrication station by oil pipe, oil-in 51 enter in low-pressure tank 52.The width short A B millimeter of the width ratio torr watt of low-pressure tank 52, is delivered to greatest extent by lubricating oil on whole torr watt width.Oil Guide face 53 is that near the torr watt surface of oil film wedge side, low-pressure tank 52 side is machined away downwards 36 millimeters, and while the side to Tuo Wa center upwardly extends 40 70 millimeters, the degree of depth is gradually reduced, until the degree of depth is zero at 40 70 millimeters, overlaps with torr tiling.
As shown in figure 12, bearing metal covers on torr watt surface.Low pressure oil is sent in low-pressure tank 52 by oil-in 51.Oil to be lubricated overflows into from Oil Guide face 53 to torr watt inside after being full of low-pressure tank.Lubricating oil is sent in oil film wedge by Oil Guide face 53 to greatest extent.The end face of low-pressure tank 52 is less with the gap in crawler shoe face so that the lubricating oil in low-pressure tank has certain pressure, contributes to being pressed in oil film wedge lubricating oil.
Traditional middle compartment uses the casting grate plate with boss, utilizes boss to be attached on support form cavity contents material, had both added weight, increase again the width of middle compartment, the energy consumption making tube mill becomes big, effectively grinds length and shortens, and material is strengthened by the resistance of middle compartment simultaneously.The support of traditional partition device for barn is integral support, first support must be placed into inner barrel before barrel soldering is integral, thus makes cylinder manufacturing process be restricted by support manufacturing process, is unfavorable for the autonomy-oriented of production procedure and carries out parallel.And cylinder directly restricts the integral production cycle of tube mill as maximum key component, its production cycle.
In the middle of in the present invention, stream is separated by compartment with air-flow so that it is respectively by different passages by middle compartment, it is to avoid stream mixes with air-flow.The middle compartment of material wind separate type uses the grate plate I of steel plate processing, the shape and size of more precise control comb seam and the overall dimensions of grate plate I, more rationally effective screening materials carrying simultaneously.The region easy to wear contacted with shell liner at middle compartment have employed angle lining plate structure, the grate plate I of middle compartment is isolated with shell liner so that change grate plate I and shell liner is non-interference, convenient and swift.Grate plate I, directly against being contained on support I, eliminates boss structure, has both alleviated weight, has reduced energy consumption, can effectively grind length by extension pipe grinding machine again, and material is more prone to by middle compartment simultaneously.Split type support I is fixing in need not being pre-filled with cylinder so that cylinder manufacturing process is parallel with support manufacturing process, does not restricts.
Conventional tube mill discharge bin uses the grate plate of casting, grate plate is with boss, boss is utilized to be mounted on support formation cavity to accommodate material, what the energy consumption of the weight and tube mill that had the most both added grate plate also occupied tube mill effectively grinds length, is unfavorable for improving tube mill yield, reducing energy consumption.The grate plate structure of this band boss bigger by resistance so that material was lengthened by the time of discharge bin discharge pipe grinding machine, is unfavorable for quick for finished product discharge pipe grinding machine and easily caused grinding.The tolerance of casting grate plate is bigger so that the comb seam size of screening materials carrying and profile are difficult to control to, and the phenomenon that abrasive media is lost easily occur.Stream crosses with gas channel, is unfavorable for that tube mill discharge and technique are gathered dust.Conventional discharge bin support uses integrated support as middle partition device for barn support, fix in must being pre-filled with cylinder before barrel soldering is integral, the manufacturing process making cylinder is restricted by discharge bin rack making operation, it is unfavorable for the autonomy-oriented of production procedure and carries out parallel, being also unfavorable for the optimization speed-raising of cylinder production cycle.
The present invention use material wind separate type discharge bin stream separated with air-flow so that it is by different passage discharge pipe grinding machines, it is to avoid both are mutually mixed.Using the grate plate II of steel plate making, the comb in grate plate II stitches by shaping, and size and profile are easily controllable simultaneously, has better effects to accurately sieving qualified fine powder, it is therefore prevented that material runs slightly loses with abrasive media.Grate plate II, directly against being contained on support, eliminates the boss structure of casting grate plate, had not only alleviated weight reduction energy consumption but also had increased tube mill and has effectively ground length, contributes to tube mill volume increase consumption reduction.The grate plate II of this structure little by resistance, it is possible to quickly by quick for finished product materials discharge pipe grinding machine, do not result in material and cross grinding phenomenon.Material wind separate type discharge bin have employed separating stent-graft II, again without fixing in being pre-filled with cylinder, contributes to cylinder and the parallel optimization of support manufacturing process and production process management.
In the present invention, the shell liner of feed bin uses new combining form.The liner plate thickness of Combination nova reduces, weight saving, and profile rule, easily manufactures simultaneously.In the present invention, liner plate can increase milling area and crushing grinding volume, improves crushing grinding efficiency, reduces the energy consumption of tube mill.
Overwhelming majority slide shoe bearing uses high-low pressure lubricating system.Low pressure oil is only delivered to hold in the palm watt side by traditional spreader groove structure, then passes through the lubricating oil suction Tuo Wanei that will lose pressure from oil suction effect of oil film wedge.This structure is by from oil suction effect fuel feeding, and fuel delivery is little, the few oil of frequent tiling oil starvation.Oil can be sent directly in tiling by the low pressure oil lubrication system used in the present invention, and keeps lubricating oil to have certain pressure, is pressed into greatest extent in oil film wedge by oil.More oil enters and advantageously forms preferable dynamic pressure oil film in oil film wedge, also takes away more heat simultaneously, improves the temperature case of slide shoe bearing.
