As shown in Figure 4, expect that the middle compartment 3 of wind separate type is by grate plate I 33, angle liner plate 35, support I 32, blind plate I 34 and center ring I 31 form.Grate plate I 33 need not be conventional cast member, but adopt wear-resisting steel plate blanking, the seam of combing is shaped by machining, finally heat-treats and forms.Grate plate I 33 profile rules are neat, the seam size uniform of combing, and deviation is little, and not putty has good effect for the qualified material of accurate screening.Angle liner plate 35 is extension intersection regions of shell liner and grate plate I 33, blind plate I 34, it is non-interference when this region is independently done to angulation liner plate 35 and made to change shell liner or grate plate I 33, and angle liner plate 35 is worn hardly, service life is very long, has not only improved the utilization rate of material but also has reduced user's cost of equipment maintenance.Support I 32 adopts Plate Welding to form, each grate plate I 33 spiro keyhole positions are equipped with steel pipe and reinforce support, the lifting fast of curved lifting blade, in time material is sent in center ring I 31 by the slotted hole on support I 32 tops, support I 32 is directly fixed on cylinder inboard wall with flat countersunk nib bolt, the fixed block that has saved conventional middle partition device for barn, has alleviated weight.The blanking of the same employing wear-resisting steel plate of blind plate I 34, has offered to comb on interior two circle blind plates simultaneously and has stitched, and has increased the available ventilation area of middle compartment 3, and a part of material also can directly fall into subordinate's feed bin by the comb seam in blind plate I 34, the Negotiation speed of quickening material.Center ring I 31 is formed by Plate Welding, ring inside is provided with stock guide 312 and dumping pit, material enters after center ring I 31 by the slotted hole in support I 32, the cavity that enters close subordinate feed bin side in ring under the effect of stock guide 312 accumulates a certain amount of rear subordinate's feed bin that automatically overflows in cavity.The passage of material stream is: qualified material enters in grate plate support I 32 from initial storehouse through the screening of grate plate I 33, under the lifting blade effect of support I 32, be conducted to the square hole of support I 32 upper ends, material enters the interior cavity near higher level's feed bin side of center ring I 31 by square hole, under stock guide 312 guiding in cavity, enter the interior cavity near subordinate's feed bin side of center ring I 31, in cavity, accumulate a certain amount of rear subordinate's feed bin that automatically overflows into.The passage of air-flow is: most of air passes through middle compartment 3 by the centre bore of center ring I 31, and remaining air passes through middle compartment 3 by the blind plate I that having comb seam 34 of grinding more than interior charge level.In whole process, material stream does not cross with air-flow, is independent of each other, and material has directly dropped on the initial abrasion site of subordinate's feed bin after by middle compartment.
As shown in Figure 5, angle liner plate 35 be higher level's feed bin shell liner, subordinate's feed bin shell liner respectively with the intersection region of grate plate I 33, 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 highly identical with the flange 21 of shell liner, is just in time sealed by shell liner, grate plate I 33 and blind plate I 34, is worn and torn hardly by material, can long-play and need not change.While changing shell liner, grate plate I 33 or blind plate I 34 separately, do not have mutual interference effect.
As shown in Figure 6, the slotted hole in support I 32 is material is entered center ring I 31 passage by support I 32.Center ring I 31 interior separations are become two toroidal cavities by dividing plate 311, in the cavity of higher level's feed bin side, is provided with stock guide I 312.Material enters after center ring I 31 under the effect of stock guide I 312, enters the toroidal cavity of subordinate's feed bin side rapidly by the notch in dividing plate I 311.After toroidal cavity accumulation slight amount, just automatically overflow into subordinate's feed bin.In the material path I 314 of dividing plate I 311, be provided with flashboard I 313, the folding size of controlling flashboard I 313 can regulate material to pass through the speed of middle partition device for barn, facilitates user according to different Operating condition adjustment output.
As shown in Figure 7, expect that wind separate type discharge bin is by angle liner plate 35, grate plate II 43, support II 42 and center ring II 41 form.The structure of angle liner plate 35 is identical with the angle lining plate structure of the middle compartment of material wind separate type, and for shell liner and the grate plate II 43 of material wind separate type discharge bin are kept apart, installation or replacing shell liner and grate plate can not interfered mutually.Grate plate II 43 adopts wear-resisting steel plate blanking, and the seam of combing is shaped by machining, and last heat treatment forms.The profile comparison rule of grate plate is attractive in appearance, the seam size uniform of combing, marshalling.Support II 42, for Plate Welding forms, adopts the good curve lifting blade of lifting effect, can fast material be sent in center ring II 41 by the slotted hole on support II 42 tops.Center ring II 41 is Plate Welding part, for material stream is separated with air-flow.
As shown in Figure 8, center ring II 41 structures of material wind separate type discharge bin 4 are 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, in the cavity of higher level's feed bin side, be provided with stock guide II 45, stock guide II is for guiding to out material rapidly in the cavity of mill side, in the material path II 47 of dividing plate II 44, be provided with flashboard II 46, the folding size of controlling flashboard flashboard II 46 can regulate material to pass through the speed of middle partition device for barn, facilitates user according to different Operating condition adjustment output.Difference is that material wind separate type discharge bin 4 supports are directly pasting cylindrical shell web, stressing conditions is better than middle compartment, and go out to grind side and there is no steel ball, therefore cancelled in center ring II 41 near going out to grind the baffle plate of side, material is entered out by stock guide can freely overflow into after the toroidal cavity of mill side transmission take in discharge pipe grinding machine.
As shown in Figure 9, a storehouse feed bin shell liner is on the basis of conventional ladder lining board, to have done to optimize to improve.The improving performance of conventional ladder lining board is better, but milling area is less.And the grinding system of most all in tube mill former configuration roll squeezer, make the feed size of tube mill less, the grinding effect of a storehouse feed bin shell liner need strengthen.The present invention has increased hoop groove on the lifting face of conventional ladder lining board, has increased effective milling area of one-level feed bin in the case of the lifting force of maintenance ladder lining board does not subtract.
As shown in figure 10, secondary feed bin shell liner adopts small ripple glaze lining board of globe.Through the crushing grinding of one-level feed bin, when material enters secondary feed bin, particle size is less, and therefore the shell liner of secondary feed bin is mainly used to grind.The milling area of small ripple glaze lining board of globe is larger, and grinding effect is good.
Shell liner adopts one-level feed bin storehouse groove ladder lining board to add the combining form of secondary feed bin small ripple glaze lining board of globe, adds some circle activation lining boards to control material flow in mill for different grinding process at secondary feed bin simultaneously.The adaptability of this shell liner combining form is good, can the larger-size material of crushing grinding charging, can successfully manage again the material that charging size is less.
As shown in figure 11, the low pressure lubricating system of slide shoe bearing is low-pressure tank structure by conventional spreader groove architecture advances.Low-pressure tank structure is by oil-in 51, and low-pressure tank 52 and Oil Guide face 53 form.Low pressure oil is transported to the oil-in 51 of holder watt side from dilute oil lubrication station by oil pipe, entered in low-pressure tank 52 by oil-in 51.The width of low-pressure tank 52, than the short A-B of the width millimeter of holder watt, is delivered to lubricating oil on whole holder watt width to greatest extent.Oil Guide face 53 is that low-pressure tank 52 sides are machined away to 3-6 millimeters downwards near the holder watt surface of oil film wedge side, and when extending 40-70 millimeters in the direction at Xiang Tuowa center, the degree of depth reduces gradually, is zero until locate the degree of depth at 40-70 millimeters, overlaps with holder tiling.
As shown in figure 12, bearing metal covers holder watt surface.Oil-in 51 is sent into low pressure oil in low-pressure tank 52.After being full of low-pressure tank, lubricating oil overflows into holder watt inside from Oil Guide face 53.Oil Guide face 53 is sent into lubricating oil in oil film wedge to greatest extent.The gap of the end face of low-pressure tank 52 and crawler shoe face is less, makes the lubricating oil in low-pressure tank have certain pressure, contributes to lubricating oil to be pressed in oil film wedge.
Traditional middle compartment adopts the casting grate plate with boss, utilizes boss to be attached to form cavity on support to hold material, has both increased weight, strengthen again the width of middle compartment, make the energy consumption of tube mill become large, effectively grind length and shorten, material strengthens by the resistance of middle compartment simultaneously.The support of traditional partition device for barn is integral support, before barrel soldering becomes entirety, must first stentplacement be entered to inner barrel, so just makes cylindrical shell manufacturing process be subject to the restriction of support manufacturing process, is unfavorable for the autonomy-oriented of production procedure and walks abreast carrying out.And cylindrical shell is as maximum key component, its production cycle directly restricts the integral production cycle of tube mill.
In the middle of in the present invention, compartment will be expected stream and flow separation, make it pass through middle compartment by different passages respectively, avoid material stream to mix with air-flow.Expect the grate plate I of the middle compartment employing steel plate processing of wind separate type simultaneously, control more accurately the comb shape and size of seam and the appearance and size of grate plate I, more reasonable effectively screening materials carrying.The region easy to wear contacting with shell liner at middle compartment has adopted angle lining plate structure, by the grate plate I of middle compartment and shell liner isolation, makes to change grate plate I and shell liner non-interference, convenient and swift.Grate plate I is directly mounted in support I, has removed 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 needn't be inserted in cylindrical shell fixing in advance, makes cylindrical shell manufacturing process and support manufacturing process parallel, does not restrict mutually.
Conventional tube mill discharge bin adopts the grate plate of casting, grate plate is with boss, utilize boss to be mounted on to form cavity on support and hold material, so both increased effective grinding length that the weight of grate plate and the energy consumption of tube mill have also taken tube mill, and be unfavorable for improving tube mill yield, reduce energy consumption.This grate plate structure with boss to pass through resistance larger, the time that makes material pass through discharge bin discharge pipe grinding machine lengthens, and is unfavorable for quick finished product discharge pipe grinding machine and easily causes grinding.The tolerance of casting grate plate is larger, makes the comb seam size of screening materials carrying and profile be difficult to control, and easily occurs the phenomenon that abrasive media is lost.Material stream crosses with gas channel, is unfavorable for that tube mill discharge and technique gathers dust.Conventional discharge bin support adopt integrated support the same as middle partition device for barn support, before barrel soldering becomes entirety, must insert in advance in cylindrical shell fixing, make the manufacturing process of cylindrical shell be subject to the restriction of discharge bin rack making operation, the autonomy-oriented and parallel development that are unfavorable for production procedure, be also unfavorable for the optimization speed-raising of cylindrical shell production cycle.
In the present invention, adopt material wind separate type discharge bin that material stream is come with flow separation, make it pass through different passage discharge pipe grinding machines, avoid both mutually to mix.The grate plate II that simultaneously adopts steel plate to make, the comb in grate plate II stitches by shaping, and size and profile are easy to control, and the fine powder qualified to accurate screening has better effects, prevented that material from running slightly and abrasive media is lost.Grate plate II is directly mounted on support, has cancelled the boss structure of casting grate plate, and not only weight reduction reduced energy consumption but also lengthened tube mill and effectively grinds length, contributed to tube mill volume increase consumption reduction.The grate plate II of this structure to pass through resistance little, can, fast by quick finished product materials discharge pipe grinding machine, can not cause material to cross grinding phenomenon.Material wind separate type discharge bin has adopted separating stent-graft II, need not insert in advance equally in cylindrical shell and fix, and contributes to parallel optimization and the production process management of cylindrical shell and support manufacturing process.
In the present invention, the shell liner of feed bin adopts new combining form.The liner plate thickness of new combination reduces, weight saving, and profile rule simultaneously, easily manufactures.In the present invention, liner plate can increase milling area and crushing grinding volume, improves crushing grinding efficiency, has reduced the energy consumption of tube mill.
Overwhelming majority slide shoe bearing adopts high-low pressure lubricating system.Traditional spreader groove structure is only delivered to low pressure oil holder watt side, then sucks Tuo Wanei by the lubricating oil that will lose pressure from oil suction effect of oil film wedge.This structure is leaned on from oil suction effect fuel feeding, and fuel delivery is little, often the few oil of tiling oil starvation.The low pressure oil lubrication system adopting in the present invention can directly be sent into oil in tiling, and keeps lubricating oil to have certain pressure, and oil is pressed in oil film wedge to greatest extent.More oil enters in oil film wedge and is conducive to form good dynamic pressure oil film, also takes away more heat simultaneously, has improved the temperature case of slide shoe bearing.
