Abstract
The invention relates to a pulverizer with impact pulverizing and extrusion-shearing pulverizing functions. The pulverizer adopts rotor dowel pins and stator dowel pins, wherein the three working faces of each rotor dowel pin as well as the three working faces of each stator dowel pin are protected by a wear-resistant element provided with an L-shaped cross section and made of hard alloy. According to a design scheme, the rotor dowel pins mounted on a rotor disc and the stator dowel pins mounted on a stator disc have the function of highly efficiently pulverizing materials through violent impact or high-speed extrusion shearing. A high-efficiency impact flour mill utilizes stator dowel pins to block quantity increase of materials; and the blocking force is enhanced and the impact probability of rotor dowel pins is increased, so as to improve the pulverizing ratio of the equipment by more than one time. A high-speed extrusion shearing pulverizer utilizes rotor dowel pins and stator dowel pins to exert great extrusion-shearing force to materials clamped between the rotor dowel pins and the stator dowel pins to rapidly pulverize high-intensity materials such as ores and ductile materials such as rubber and plastic, and has the outstanding advantages of high pulverizing ratio, high efficiency, high effective electric energy utilization ratio and the like. The effective electric energy utilization ratio of the pulverizer provided by the invention reaches more than 30 percent and is a dozen times that of the conventional ball mill.
Description
Technical field
The present invention relates to a kind of pulverizer with bump pulverizing and extrusion shearing crushing function, this pulverizer is used for various fragility or the plasticity solid material of certain particle size are ground into fine particle at numerous areas such as cereal processing, feed processing, metallurgy, Chemical Engineering, plastics, medicine, building, electronics and the energy.
Background technology
The wheat flour milling industry is widely used a kind of size reduction machinery of impacting type flour mill by name both at home and abroad.Percussion grinder is by casing, and rotor part, stator component and motor form.Wherein rotor part comprises wheel hub, is fixed on the disk rotor dish on the wheel hub and is installed at least 3 circles, 16～40 rotor pins of every circle on the rotor disk.Stator component comprises cover plate, fixes stator disc on the cover board and is installed in the circle of at least 3 on the stator disc, 20～60 stator pins of every circle.
The working portion of existing rotor pin and stator pin all is that cross section is foursquare four prisms cylinder, and the coupling part is one section screw rod or polished rod.When parts were installed, described screw rod or polished rod pierced into the Kong Houyong fastening nuts of rotor disk or stator disc or fix with welding method.During equipment operation, rotor pin and stator pin can touch material, the equipment crushing function is had a direct impact and the surface of quick abrasion is radial surface in the face of material.They are respectively that the rotor pin radially clashes into working face and stator pin and radially clashes into working face (surface that following handle can directly affect the equipment crushing function all is called the working face of pin).The radially bump working face of existing rotor pin and stator pin all welds the hard metal tip protection.
After existing percussion grinder general assembly was finished, the tangential surface of stator pin was parallel with the tangential surface of rotor pin, and radial clearance is 1～2mm between rotor pin and the stator pin.The raw meal particle size that the percussion grinder (other industry is seldom used percussion grinder at present) that uses in flour mill is processed is all below 0.4mm, rotor pin and stator pin can not touch any one material particles simultaneously, so percussion grinder can only lean on pin on the rotor disk of High Rotation Speed to reach the purpose of comminuting matter at space bump material particles.
Analyze from existing percussion grinder operation principle, all enter the machine material and all move in the circumferential direction of the circle with certain speed under the effect of rotor power and rotor pin impact.The material particles movement velocity is larger, and homodromous its intensity of rotor pin bump is just lower, and the pulverized probability of material particles is also less.The barrier effect of stator pin is to reduce to zero bumping against its material particles movement velocity of radially clashing on the working face, also can be radially clashing into the material particles movement velocity decrease of working face near it, impact strength and crushing effect when making the rotor pin radially clash into working face to clash into this part material obviously improve.
Yet in the prior art, the crest line position, both sides that the rotor pin radially clashes into working face can only bump against in extremely of short duration moment that (being radial clearance between rotor pin and the stator pin) stops the material particles that slows down because the stator pin radially clashes into working face in 1～2mm space at and crest line position, the outside inboard near it.Except this moment, the stopping of stator pin does all is idle work (low especially being knocked of only a few high-speed motion and intensity material particles strikes also may be broken on the stator pin) substantially.And, this moment be in the stator pin radially clash into material on the working face (being pressed into the even distributional analysis of machine material, this part material ratio many 1.5～4 times of material in 1～2mm radial clearance between rotor pin and stator pin) rotor pin hit less than.Obviously, the stator pin stop rear deceleration and can allow material that the rotor pin strikes very little (probability that the rotor pin strikes the material that is stopped by the stator pin and slow down is too little) be that prior art one is lacked greatly.In addition, only have the pin of a working face (namely clashing into the one side of material in the prior art) to be used on the percussion grinder, can only lean on rotor pin space to clash into the fragility solid material of ground cereal equal strength lower (compression strength of wheat is about 6MPa), can't powder ore etc. high strength (compression strength of rock is the fragile material of 20MPa～200MPa).Efficient when percussion grinder of the prior art is used for the toughness material such as crushing rubber and plastics is also lower.Therefore, to cause the percussion grinder applicable surface narrow be that prior art one is lacked greatly to the fit structure of existing stator pin and rotor pin.
Gap between rotor pin and the stator pin is less in long-term a large amount of facts have proved, the effect that the stator pin stops is just larger, impacting type flour mill disintegrating process effect is just better, and the wearing and tearing that while rotor pin and stator pin radially clash into working face are corresponding also faster.Prior art has been welded hard metal tip at the pin working face, makes pin prolong at least decades of times service life.But test data shows: on the pin that is welded with hard metal tip of the percussion grinder in 1 year of flour mill's use, the wearing and tearing of edges and corners, hard metal tip both sides reach about 0.2mm.Infer accordingly, if when this pin is used for powder ore class high strength material, the wear extent in edges and corners, both sides every year of hard metal tip is at least at 1～2mm.Rotor pin and stator pin bump gap increase 1～2mm must make equipment operating efficiency, yield rate and economic benefit etc. obviously reduce, and therefore, service life is short to be another shortcoming of the pin of existing percussion grinder.
Analyze in theory, each rotor pin can both form once strongly bump near the moment of each stator pin.Calculate like this, the strong bump that form each second in impact disintegrating mill casing reaches 30～600,000 times.Many advantages such as therefore, the size reduction machinery close with most of functions and use occasion with roller flour mill compared, and that percussion grinder has is simple in structure, crushing function is powerful, price is cheap, and installation and maintenance are convenient, and energy consumption is low and widely applicable.
In powder technology (research is ground into an interdiscipline of the characteristic etc. of pulverous technique and equipment and various powders, inter-trade comprehensive extremely strong technology-oriented discipline with solid material) field by a kind of gyratory crusher that is formed by two truncateds cone.Gyratory crusher to decide cone (claiming again outer cone) be the part of frame, mantle (claiming again inner cone) is fixed on the main shaft.The center line of main shaft intersects at the O point with the center line of fixed cone, main shaft is suspended on the intersection point O, and the main shaft lower end is inserted in (is deciding on the center line of cone at the center of lining) in the eccentric bush actively, like this, during the main shaft rotation, mantle is done partially to revolve along the inner surface of fixed cone and is moved.Near deciding the cone place, material is subjected to mantle extruding and shear action and is pulverized; Decide the cone place departing from, broken material falls to discharging by self gravitation.Gyratory crusher is the machinery that pushes-shear grinding mode work.The advantages such as it is large that it has production capacity, and comminution ratio (enter the machine average grain diameter and go out the ratio of machine average grain diameter) is large, and unit power consumption is low, but complex structure is also arranged, investment cost is large, repair and maintenance is difficult and can only be used for the shortcoming such as broken larger particles material.Although ball mill has strong adaptability very widely, production capacity is large, comminution ratio is large, simple in structure, operation is reliable and the advantages such as good airproof performance and field of powder engineering is used, also organism is heavy, investment is large, large, the abrasive body of noise and liner plate consumption is large and the shortcoming such as inefficiency in the time of need joining expensive reductor, work.Wherein effectively utilization rate of electrical only is about 2% to be its most outstanding and harm is maximum shortcoming.

Such as Fig. 2 to Fig. 6 and (dotted line is depicted as rotor disk 14 among Fig. 4) shown in Figure 1, described rotor pin 5 is identical with described stator pin 4 structures, including cross section is foursquare four prism type steel billet 2, and steel billet 2 is provided with coupling part 1, and coupling part 1 is screw rod or polished rod.
The adjacent two sides of described four prism type steel billet 2 are respectively as striking face and compressive plane, striking face and compressive plane general designation working face, on the working face welding or be bonded with wear member 3, the cross section of wear member 3 is L-shaped, two non-working surfaces of the two ends that wear member is L shaped and steel billet 2 flush.
Wear member 3 cross section corners are provided with hypotenuse, the inclined-plane 3C that makes wear member 3 form orthogonal wide 3A, leptoprosopy 3B and connect wide 3A and leptoprosopy 3B, and the angle of the angle α of inclined-plane 3C and leptoprosopy 3B is 15 °～35 °.
Wide 3A of described wear member 3 is as the radially bump working face 6 that radially clashes into working face 10 and stator pin 4 of rotor pin 5, the leptoprosopy 3B of described wear member 3 is as the tangential extruding working face 13 of rotor pin 5 and the tangential extruding working face 7 of stator pin 4, and the inclined-plane 3C of described wear member 3 is as the inclined cut 11 of rotor pin 5 and the inclined cut 9 of stator pin 4.
Described wear member 3 is formed by carbide alloy or the manufacturing of special cermacis class ultra-hard abrasive material.The inclined-plane 3C of described wear member 3 and leptoprosopy 3B are serrated-surface.
The tangential extruding working face 13 of described rotor pin 5 is tangent with the A cylinder 21 at this place.The tangential extruding working face of stator pin 4 and the angle β of A cylinder 21 between the tangent plane at stator pin 4 axis places that passes stator pin 4 axis are 10 °～30 °.
The present invention in operation process, the radial clearance between rotor pin 5 and the stator pin 4 always one from being up to minimum change procedure.When rotor pin 5 begins near a certain stator pin 4, the smallest radial spacing of rotor pin benchmark crest line 12 and stator pin the second crest line 22 be called between rotor pin 5 and the stator pin 4 maximal clearance L1(as shown in Figure 5).
When rotor pin 5 is about to away from a certain stator pin 4, the smallest radial spacing of the tangential extruding working face 7 terminal crest lines of rotor pin benchmark crest line 12 and stator pin be called between rotor pin 5 and the stator pin 4 minimum clearance L2(as shown in Figure 6).
When the present invention worked, the material that enters the space between pulverizer housing 34 sub-disks 15 decided at the higher level but not officially announced and the rotor disk 14 moved to outer rim from casing 34 centers under the impact effect of centrifugal force, wind-force and rotor pin 5 that rotor forms.When the present invention was used for the processing granularity less than the material of minimum clearance L2, tiny entered the machine material in motion process, after bump is pulverized repeatedly by at least 3 circle rotor pins 5, discharges from discharging opening 31.When the present invention is used for the material of processing granularity between minimum clearance L2 and maximal clearance L1, granularity clamps the moment of holding greater than the larger material particles of minimum clearance L2 is inevitable having near L1 place, maximal clearance by rotor pin 5 and stator pin 4, after this moment, 5 motions of rotor pin, the tangential extruding working face 7 that the rotor pin tangentially pushes working face 13 close stator pins must apply huge extruding-shearing force to material particles, makes maximum material particles broken rapidly.After the large granular materials fragmentation, the rotor pin tangentially pushes working face 13 to be continued must be expressed to less material particles and make its moment broken near the tangential extruding working face 7 of stator pin ... until after granularity all pulverized greater than the material particles of minimum clearance L2, the material of having pulverized was discharged from discharging opening 31.
Use, installation process and specification (referring to accompanying drawing 1 to 6):
When the present invention was used for the processing granularity less than the material of minimum clearance L2, equipment mainly reached the comminuting matter purpose by rotor pin space bump material particles, so claim high-efficiency percussion grinder; When being used for the material of processing granularity between minimum clearance L2 and maximal clearance L1, equipment mainly reaches the comminuting matter purpose by the material particles of rotor pin extrusion shearing between rotor pin and stator pin of high-speed motion, so claim the high-speed extrusion shear pulverizer.
When stator component of the present invention was installed, the tangential extruding working face 7 of stator and the angle β of A cylinder between the tangent plane at axis place that passes this stator column pin axis were 10 °～30 °.This measure make first stator pin 4 radially, tangential and three surfaces in the face of material that tilt have all had the function that stops material movement, second make rotor pin 5 in rotor disk 14 rotation processes with each stator pin 4 near the time, the descending change procedure in gap between a rotor pin 5 and the stator pin 4 is arranged, pulverize for extrusion shearing and create necessary condition.
When the present invention worked, material entered space between casing 34 sub-disks 15 decided at the higher level but not officially announced and the rotor disk 14 from charging aperture 32, the rotation of motor 40 rotor drivens.The centrifugal force that rotor forms and the impact of wind-force and rotor pin 5 force material to move to outer rim from casing 34 centers.Analyze from the equipment operation principle, rotor pin 5 of the present invention is connected with rotor disk 14, wheel hub 39 and motor 40 rotors, and rotor pin 5 has by 1/2mv
2(m is the quality of whole rotor part in the formula, it wants kilograms up to a hundred usually, the kinetic energy numerical value that rotor speed v calculates at 1000r/min～3000r/min) usually, this value ratio can be greatly thousands of times by the combination of pincer attack material particles, therefore, the present invention can easily pulverize percussion grinder and hit the not broken high strength fragile materials such as ore.Having stronger smashing capability is of the present invention one large advantage.
When the present invention used as high-efficiency percussion grinder, minimum clearance L2 numerical value was got 0.5～1.5mm, and maximal clearance L1 numerical value is got 4～10mm.Tiny enters the machine material in motion process, after bump is pulverized repeatedly by at least 3 circle rotor pins 5, discharges from discharging opening 31.In this process, 4 three working faces of stator pin can both stop material.The stator pin radially clashes into material particles that working face 6 blocks can outwards skid off along its surface rotor pin 5 bumps for these stator pin 4 outsides.Having that the stator pin 4 tangential extruding working faces 7 of serrated-surface and movement velocity that inclined cut 9 can make all hit the material on its sawtooth rib die-off is again bounce-back or to skidding off near rotor pin 5 directions after zero, so stator pin 4 stops that the effect of material movement is much higher more than the effect of stator pin obstacle material motion in the prior art among the present invention.Because of maximal clearance L1 numerical value (4～10mm) than the gap between existing percussion grinder rotor pin and the stator pin (1～2mm) large 2～10 times just Duo 2～10 times than existing percussion grinder so enter the quantity of material in this 4～10mm space.In addition, 3～20 times of analyses of minimum clearance L2 according to maximal clearance L1, enter the material in this 4～10mm space, the overwhelming majority can be hit on the zigzag faceted pebble of the tangential extruding working face 7 of stator pin and inclined cut 9, so not only quantity is many but also the amplitude of movement velocity decay is large for the material that is stopped by stator pin 4.Be used in function that rotor pin 5 on the high-efficiency percussion grinder radially clashes into working face 10 and inclined cut 11 and all be and directly clash into material particles and with its pulverizing.Rotor pin benchmark crest line 12 is positions (it also is that the rotor pin tangentially pushes working face 13 initial positions simultaneously) of the tangential extruding working face 7 of the most close stator pin in rotor pin 5 inclined cuts, also is the strongest position of crushing function (effect of radially clashing into working face two inclines with existing rotor pin 5 is equal to).The rib of each bar projection of rotor pin inclined cut 11 serrated-surfaces all makes rotor pin 5 increase once to clash into the chance that is stopped the material of movement velocity rapid drawdown by stator pin 4.Cause is far away than rotor pin benchmark crest line 12 with the distance of the tangential extruding working face 7 of stator pin, intensity and the crushing effect of these crest line bump materials can be lower than rotor pin benchmark crest line 12, but increase at least 5 faceted pebbles that can strongly clash into material, the degradation rate of rotor pin 5 bumps is increased substantially.Rotor pin 5 inventory with stator pin 4 gaps increases 2～10 times according to entering, the amplitude probability large and rotor pin 5 high strength bump material of the material movement velocity attenuation that stopped by stator pin 4 increases at least 4 times of these 3 analysis-by-synthesis, is used for the present invention that bump pulverizes higher 1 times than existing percussion grinder at least on degradation rate.
When the present invention used as the high-speed extrusion shear pulverizer, the numerical value of minimum clearance L2 and maximal clearance L1 was determined according to factors such as the granularity of material to be machined and intensity.The barrier functionality of 4 three working faces of stator pin is identical with aforementioned percussion grinder.Different is: the tangential extruding working face 7 of stator pin and the major function of inclined cut 9 are that the tangential extruding working face 13 with rotor pin 5 vises material particles, and impose extrusion shearing power and make material particles broken.The tangential extruding working face 7 of stator pin and inclined cut 9 serrated-surfaces can strengthen pincers and hold power and frictional force raising degradation rate.
When the present invention used as the high-speed extrusion shear pulverizer, rotor pin 5 of the present invention radially clashes into working face 10 and inclined cut 11 still all is the working face that directly clashes into material particles.But because being knocked the factor affecting such as the high and particle of material strength is large, generally, bump can't the comminuting matter particle, no longer does the function discussion that rotor pin 5 radially clashes into working face 10 and inclined cut 11 so bump is pulverized.The major function that rotor pin 5 radially clashes into working face 10 is to allow hit at its surperficial material outwards slip into the backward first Wedge-shaped space of (here take the direction of motion of rotor pin 5 as forward direction, otherwise being backward), tip that the tangential extruding working face 7 by this pin inclined cut 11 and stator pin forms.The major function of rotor pin 5 inclined cuts 11 is the most advanced and sophisticated first Wedge-shaped spaces backward of tangential extruding working face 7 compositions with the stator pin, hold and vise from rotor pin 5 the place aheads with from rotor pin 5 and radially clash into the material particles that working face 10 slips into, and these material particles are applied extrusion shearing power, force material particles broken.Starting point is that the rotor pin of rotor pin benchmark crest line 12 tangentially pushes working face 13 and starting point is the most advanced and sophisticated second Wedge-shaped space forward of tangential extruding working face 7 compositions of the stator pin of stator pin benchmark crest line 8.Rotor pin 5 travels forward, the second Wedge-shaped space reduces, can vise at the rotor pin and tangentially push material particles between the tangential extruding working face 7 of working face 13 and stator pin, and these material particles are applied extrusion shearing power, force material particles broken.Rotor pin 5 the serrated-surfaces tangential and inclined cut can increase pincers and hold power and increasing shearing force, and and then the degradation rate of raising equipment when working.
When the present invention uses as the high-speed extrusion shear pulverizer, rotating speed in the linear velocity of the epitrochanterian pin motion of 1000r/min～3000r/min up to 20m/s～100m/s.With so high speed shear must be efficiently light toughness materials such as crushing rubber, plastics, therefore, can efficient pulverizing rubber, the toughness material such as plastics also is one of outstanding advantage of the present invention.
The tension of nearly all solid-state material and shearing strength are all low more than compression strength, so, must be remarkable with the low advantage of energy consumption of the present invention that is cut into main grinding mode.Energy consumption when in addition, the present invention works only has no-load running energy consumption, comminuting matter energy consumption, crushing material to produce 4 energy consumptions such as heat power consumption and rotor banding animal material sports energy consumption.The present invention is simple in structure, and no-load power consumption is lower than most of size reduction machineries.When the present invention worked, rotor pin 5 drove material and moves in a circle, and material also moves to the rotor outer rim rapidly from rotor center simultaneously, and discharged from the discharging opening 31 of casing 34.Concerning each rotor pin 5, drive same material particles motion for once (existing ball mill and gyratory crusher etc. all are repeated multiple times), so that the present invention drives the material movement energy consumption is also much lower than most of size reduction machineries.With above-mentioned combined factors analysis, the present invention is likely that energy consumption is minimum up to now, effectively the highest size reduction machinery of energy utilized rate.
The all working face of four prism type steel billet 2 all uses the method for welding or bonding L font wear member 3 to protect among the present invention.When adopting the rotor rotation of present device, the peak crest line that any one rotor pin tangentially pushes at least 5 strap saw tip surfaces on the working face 13 is in the same A cylinder 21 substantially, and the wear extent during work is basic identical.At least 10 strap saw tip surfaces have the function that stops material movement and apply frictional force to the material of being held by pincers on the tangential extruding working face 7 of stator pin of the present invention.When equipment operation, the probability of these strip crest line wearing and tearing is identical substantially.Can draw to draw a conclusion: the situation that a certain sawtooth rib Fast Wearing can not occur only having.Therefore, tangential extruding working face 7 most of sawtooth rib wearing and tearing of only having the rotor pin tangentially to push working face 13 whole sawtooth rib wearing and tearing or stator pin just can occur strengthening the situation that causes crushing function to descend because of rotor pin 5 and stator pin 4 gaps.Equal and the comminution ratio same analysis contrast by the quantity of pulverizing equal material, the present invention welds the service life of hard metal tip pin to 5 times of the youthful and the elderlys than existing.
At last, the present invention can form the basis transformation of various existing bumps pulverizing (abrasive dust) machines.Adopt technical spirit of the present invention to pulverize various bumps and transform, as can be to being that the structure of the rotor pin of No. 201210186136.7 patents (water-cooled percussion grinder) and stator pin and rotor pin and stator pin are installed in position relationship on rotor disk and the stator disc and transform by the present invention and just form water cooling high-efficiency percussion grinder or water cooling high speed extrusion shearing pulverizer with application number.Its function is except to one of the material to be machined cooling, and is all identical with the present invention.Therefore, the various improvement of carrying out on basis of the present invention, utilize the conversion on the various forms that technical spirit of the present invention carries out all to drop within protection scope of the present invention.
