Description

There is the pulverizer that clashes into pulverizing and extrusion shearing crushing function

Technical field

The present invention relates to a kind of pulverizer that clashes into pulverizing and extrusion shearing crushing function that has, this pulverizer is used for the various fragility of certain particle size or plasticity solid material to be 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

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 wheel hub and is arranged at least 3 circles, every circle dozens of rotor pin on rotor disk.Stator component comprises cover plate, fixes stator disc on the cover board and is arranged on the circle of at least 3 on stator disc, every circle dozens of stator pin.Existing percussion grinder mainly clashes between rotor pin and the stator pin material particles in 1~2mm and reaches the object of comminuting matter strongly by the rotor pin of high-speed motion.More than ten years facts have proved that the large scale application of wheat flour milling industry percussion grinder has simple in structure, crush efficiency, price is cheap in a large number, many advantages such as the convenient and energy consumption of installation and maintenance is low, but also have simultaneously clash into after material temperature rise higher and clash into the shortcomings such as impurity output of many times flour ash content raising such as containing wheat skin.In addition, limited because of space effect of impact power, while clashing into the toughness materials such as abrasive dust crushing rubber and plastics, efficiency is on the low side, and can not be used for the high strength materials such as powder ore.Therefore applicable surface is partially narrow is also the shortcoming of existing percussion grinder.

In powder technology (solid material 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 by research) field by a kind of gyratory crusher being formed by two truncateds cone.Gyratory crusher to determine cone (claiming again outer cone) be a part for frame, mantle (claiming again inner cone) is fixed on main shaft.The center line of main shaft intersects at O point with the center line of fixed cone, it is upper that main shaft is suspended on intersection point O, and main shaft lower end is inserted in (center of lining is on the center line of determining cone) in eccentric bush actively, like this, when main shaft rotation, mantle does partially and revolves and move along the inner surface of fixed cone.Near determining cone place, material is subject to mantle extruding and shear action and is pulverized; Determine 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 machine average grain diameter and go out the ratio of machine average grain diameter) is large, and unit power consumption is low, but also have complex structure, investment cost is large, repair and maintenance is difficult and can only be used for the shortcomings such as broken larger particles material.And field of powder engineering application although ball mill has strong adaptability very widely, production capacity is large, comminution ratio is large, simple in structure, operation is reliable and the advantage such as good airproof performance, also large, large, the abrasive body of noise and liner plate consumption is large and the shortcoming such as inefficiency need join expensive reductor, work time of organism heaviness, investment.Wherein effectively utilization rate of electrical is only that 2% left and right is that it is the most outstanding and endanger maximum shortcoming.

It is the new technology (be all called for short and announced new technology below) with the pulverizer that clashes into pulverizing and extrusion shearing crushing function that Chinese patent application 201210481139.3 has been announced a key name, and this technology is also present inventor's research and development achievement.This technology attempts to be improved equipment crushing function, extended pin service life and make pulverizer have extrusion shearing crushing function by following technological means: the pin that 1. designs a welding cross section and be L shaped wear member; 2. on wear member, arranging with tangential working face angle is the inclined cut of 15 °~35 °; 3. in the time that stator pin is installed on stator disc, making the tangential working face of stator pin and taking stator disc axis centered by the tangent plane angle on the face of cylinder of line crossing with it is 10 °~30 ° (are all called for short below stator pin and reverse 10 °~30 °).Submitting to after patent application, we develop model machine and test, and find that test testing result and the desired value of model machine crushing function has a long way to go.

After test, present inventor creatively uses again wear-resistant test (processing fine sand with model machine) to analyze the reason that reason result of the test and desired value differ greatly.According to model machine crushing function and wear-resistant test result analysis, applicant finds that the technology in this aforementioned patent applications exists following obviously shortcoming:

1. the flour extraction rate that the wheat endosperm below 0.5mm detects by model machine processing granularity is only processed high 15% left and right of existing percussion grinder of material of the same race than contrast test, reach far away the crushing function of analyzing in patent document and improve the level of 1 times.This prove theory analysis at that time according to wrong or analyze comprehensively not, analytical method is not comprehensively, rationally.

2. wear-resistant test was carried out after 20 hours, detect and find that first sawtooth of the tangential working face of rotor pin has just had the vestige (the crest line tip of sawtooth tip end surface projection grinds gloss) being ground to, but the tip of the tangential working face end of stator pin sawtooth has been found out obviously stock removal (crest line of sawtooth tip end surface projection is worn away, and glossy part is than the wide several times of protruding crest line).Analyze accordingly, the tangential working face end of stator pin sawtooth rapid wear (the each several part rate of wear is inhomogeneous), cause minimum clearance between rotor pin and stator pin to increase fast, though pastern divides wearing and tearing, but minimum clearance also causes equipment degradation rate to reduce after increasing fast and pin is difficult to reach the index described in aforementioned patent document service life, this becomes announces one of new technology and lacks greatly.

3. wear-resistant test was carried out after 20 hours, detected and found that the tangential working face of rotor pin only has first sawtooth tip to have the vestige being ground to, the vestige that sawtooth below is not all ground to.This proves that the later sawtooth of first sawtooth is inoperative, do not interact with material, in this patent specification, relevant discussion do not square with the fact, and the fact shows that the zigzag structure of the tangential working face of rotor pin does not play due effect, and this becomes the shortcoming of announcing new technology.

4. (plastic density is little for processing the plastic pellet that granularity is greater than minimum clearance between rotor pin and stator pin for model machine, there is certain toughness, clash into broken proportion certainly little than extrusion shearing, so press the analysis of high-speed extrusion shear pulverizer) time, find to contain the particle that is greater than in a large number minimum clearance between rotor pin and stator pin in the material after processing.We analyze judgement accordingly, and rotor pin inclined cut clamps together with the tangential working face of stator pin that to hold material particles probability low should be main cause.Carry out further creative analysis by present inventor, finding to cause pincers to hold the reason that probability is low is that rotor pin inclined cut is excessive with tangential working face angle.Therefore announced in new technology that inclined cut and inclined cut and tangential working face angle to be set excessive at rotor pin be also to have announced new technology shortcoming.

As shown in Figures 2 to 6, centered by the axis of rotor disk 8, the wear member 12 of described rotor pin 6 and stator pin 5 has the tangential working face 12A that intersects vertically and two working faces of working face 12C (these two working faces are as the tangential working face of rotor pin 6 and stator pin 5 and working face radially) radially.On wear member 12, taking the intersection of described two working face 12A, 12C as front end, tangential working face 12A front portion is standard serrated-surface, and this standard serrated-surface is provided with sawtooth51; The end of tangential working face 12A is provided with a first special-shaped sawtooth 12B, and the top width of this first special-shaped sawtooth 12B is at least the tangential working face 12A of wear member front portion sawtooth51 tooth bottom width degree B(are as shown in Figure 3) twice, be preferably 5~10 times and the first special-shaped sawtooth 12B and be more than or equal to 4 millimeters along the width (i.e. the top width of the first special-shaped sawtooth 12B) of rotor running circumferencial direction.

As shown in Figure 4, taking with the imaginary circles cylinder of stator disc 7 or rotor disk 8 coaxial lines as A cylinder 52, the tangential working face of stator the pin 5 and angle the tangent plane at stator column pin axis place is α through the A cylinder 52 of this stator column pin axis, 5 °≤α≤20 °.

As shown in Figure 4, the tangential working face of rotor the pin 6 and angle the tangent plane at rotor pin 6 axis places is β through the A cylinder 52 of these rotor pin 6 axis, 5 °≤β≤20 °.

As shown in Fig. 3 and Fig. 4 to Fig. 6, taking wear member 12 the above two working face 12A, 12C intersection as front end, the radially working face front portion of the wear member 12 of rotor pin 6 and stator pin 5 is the serrated-surface of standard, and this standard serrated-surface is provided with sawtooth51; Radially the end of working face is provided with a second special-shaped sawtooth 12D, and the top width of this second special-shaped sawtooth 12D is at least working face front portion radially sawtooththe twice of 51 tooth bottom width degree.

As shown in Fig. 4, Fig. 3 and Fig. 5 and Fig. 6, stator pin 5 is along the circumferential direction uniformly distributed to be arranged in stator disc 7(Fig. 4 and represents by solid outline centered by the axis of stator disc 7) on, rotor pin 6 is along the circumferential direction uniformly distributed to be arranged in rotor disk 8(Fig. 4 and represents with dotted outline centered by the axis of rotor disk 8) on, have the sub-pin 5 of a delineation except innermost circle rotor pin 6 only has outside, all the other every circle rotor pins 6 are all clipped between the sub-pin 5 of inside and outside each delineation.The wear member 12 of stator pin 5 in the face of the radial surface (being the radially working face 12C of wear member 12) of material be radially working face 21 of stator pin 5, wide especially the second special-shaped sawtooth in the top of this working face end is as radially working face abnormity sawtooth 20 of stator pin 5.With stator pin 5 stator pin 5 inside cuttings that radially working face 21 intersects vertically be the tangential working face 23 of stator pin 5 to surface (being the tangential working face 12A of wear member 12), the first wide especially special-shaped sawtooth of top of stator pin 5 tangential working face 23 ends is the special-shaped sawtooth 22 of the tangential working face of stator pin 5.The radial surface (being the radially working face 12C of described wear member 12) that on rotor pin 6, wear member 12 is faced material is radially working face 25 of rotor pin 6, and the wide especially sawtooth (i.e. the second described special-shaped sawtooth) in top of working face 25 ends is radially working face abnormity sawtooth 26 of rotor pin 6.The tangential surfaces, rotor pin 6 outsides (being the tangential working face 12A of wear member 12) that intersect vertically with the radially working face 25 of rotor pin 6 are the tangential working faces 27 of rotor pin 6, and the wide especially sawtooth (being described the first special-shaped sawtooth) in the top of this working face end is the tangential working face abnormity of rotor pin 6 sawtooth 28.

As shown in Figure 4, Figure 5 and Figure 6, when rotor of the present invention is pressed direction rotation shown in Fig. 4 arrow, the radial clearance between rotor pin 6 and stator pin 5 is a change procedure from maximal clearance to minimum clearance always.When rotor pin 6 starts to approach a certain stator pin 5, on the tangential working face 27 of rotor pin, on the most advanced and sophisticated and tangential working face 23 of stator pin 5 of first sawtooth, the smallest radial spacing at first sawtooth tip is called maximal clearance L1(between rotor pin 6 and stator pin 5 as shown in Fig. 5 of a-quadrant in Fig. 4 and amplification).When rotor pin 6 is about to away from a certain stator pin 5, the tooth top of the tangential working face abnormity of rotor pin sawtooth 28 and the smallest radial spacing between the tooth top of the special-shaped sawtooth 22 of the tangential working face of stator pin 5 are called minimum clearance L2(between rotor pin 6 and stator pin 5 as shown in Fig. 6 of B region and amplification in Fig. 4).Efficient for pursuing, when the present invention designs, should dwindle as far as possible minimum clearance numerical value, the numerical value that simultaneously will ensure maximal clearance L1 is 4~20 times of minimum clearance L2.

When the present invention works, entered by charging aperture 2 under the impact effect of centrifugal force, wind-force and rotor pin 6 that the material in the space between casing 4 sub-disk 7 decided at the higher level but not officially announced and rotor disk 8 forms at rotor and move to outer rim from casing 4 centers.Material particles, in motion process, through rotor pin 6 and stator pin 5 when narrow and small space, is repeatedly clashed into by least 3 circle rotor pins 6 or is held between rotor pin 6 and stator pin 5 after extrusion shearing fragmentation by pincers, discharges through discharging opening 1.

The present invention is when processing the material that granularity is less than minimum clearance L2 between rotor pin 6 and stator pin 5, rotor pin 6 can not contact material particles with stator pin 5 simultaneously, equipment mainly clashes into and reaches comminuting matter object by rotor pin 6, so the present invention can be called high-efficiency percussion grinder in this case.High-efficiency percussion grinder in the course of the work, all enter machine material under the effect of rotor centrifugal force, wind-force and rotor pin 6 impacts, all be certain to do circumferencial direction motion and radial motion from inside to outside simultaneously, all enter machine material all can be simultaneously circumferentially and radially both direction motion.Bump against the stator pin material particles that radially movement velocity die-offs on working face 21 in outwards motion, while being clashed into by the rotor pin 6 in these stator pin 5 outsides, impact strength must increase.And bump against the material particles that on the tangential working face 23 of stator pin, movement velocity die-offs, and to be clashed into by the rotor pin 6 of these stator pin 5 inner sides, the amplification of impact strength is larger.L1 all more than 4mm (gap between existing percussion grinder rotor pin 6 and stator pin 5 mostly is 1mm) in maximal clearance between rotor pin 6 of the present invention and stator pin 5, means that the inventory that can enter the space between rotor pin 6 and stator pin 5 when the present invention works is at least two or three times of prior art.Because all materials all move along both direction circumferentially and radially, so have at least 80% can strike on stator pin 5 tangent-saw profile of tooth working faces in this part material, it is zero that the movement velocity of both direction is all die-offed.On the tangential working face 27 of rotor pin of the present invention, have 6 sawtooth at least, the design size of minimum clearance L2 between the tangential working face abnormity sawtooth 28 of rotor pin and the tangential working face abnormity of stator pin sawtooth 22 is 1mm, sawtooth before the tangential working face abnormity of rotor pin sawtooth 28, sawtooth position of every reach, between the tangential working face abnormity of sawtooth and stator pin 5 sawtooth 22, distance increases 0.2mm.Because sawtooth quantity is many on the tangential working face of rotor pin 6, the tangential working face of these sawtooth and stator pin 5 distance be mostly less than 2mm(percussion grinder flour mill long-term widely apply facts have proved that between rotor pin 6 and stator pin 5, gap is 2mm time, equipment still has goodish crushing function), add the tangential working face 21 of stator pin of the present invention owing to being provided with sawtooth, the movement velocity of a large amount of material particles can be die-offed is zero, impact strength is increased substantially, so the present invention does the high-efficiency percussion grinder used time, degradation rate is than the degradation rate of existing percussion grinder and announced all high 1 times of left and right of actual measurement degradation rate of new technology prototype test.

The present invention is when processing the material that granularity is greater than minimum clearance L2 between rotor pin 6 and stator pin 5, the present invention mainly applies extrusion shearing active force and reaches comminuting matter object be held in material particles between the two by pincers by rotor pin 6 and stator pin 5, so the present invention can be called high-speed extrusion shear pulverizer (rotor pin 6 linear velocities are mostly more than 60m/S) in this case.When the work of high-speed extrusion shear pulverizer, when being entered the material of casing 4 by charging aperture 2 distance being relatively large between rotor pin 6 and stator pin 5 near stator pin 5, rotor pin 6 is near each stator pin 5, distance reduces gradually between the two, the moment that between distance is tending towards equating with material particles granularity, rotor pin 6 clamps and holds material particles together with stator pin 5, and rotor pin 6 continues motion, and huge extrusion shearing power is pulverized rapidly material particles.In the present invention, when stator pin 5 is installed on stator disc 7, make stator pin 5 tangential working face and and its crossing centered by stator disc 7 axis the angle α between the tangent plane on the face of cylinder (being A cylinder 52) of line be 5 °~20 ° angles; When rotor pin 6 is installed on rotor disk 8, also to make rotor pin 6 tangential working face and crossing with it centered by rotor disk 8 axis the angle β between the tangent plane on the face of cylinder of line be 5 °~20 ° angles; These material particles pincers that just ensured that rotor pin 6 and stator pin 5 can be positioned at the overwhelming majority are between the two held, and form two sawtooth working faces to the duty of rubbing with the hands.So, for the solid material of all materials, as long as its granularity is greater than described minimum clearance L2, the present invention can both effectively pulverize it as high-speed extrusion shear pulverizer, and crushing material rate (pointing out the pulverized probability of machine material) and crush efficiency (characterizing the speed of comminuting matter) are far above similar size reduction machinery.

The present invention arranges the special-shaped sawtooth that width strengthens on the wear member 12 of pin, suitably strengthen the measures such as pin entirety, special-shaped teeth sizes and pin can be improved to tens times service life, even tens times, the pin special circumstances faster of wearing and tearing while making pin (comprising rotor pin 6 and stator pin 5) can adapt to high-speed extrusion shear pulverizer processing high strength material, ensure high-speed extrusion shear pulverizer can be within considerable time high-efficiency operation.

Research and development explanation:

As stated in the Background Art, the present inventor has found to announce by advanced development and lot of experiments three shortcomings greatly that new technology exists can cause that all objects of this technology cannot realize, and further analyze and research the on this basis operation principle of clashing into pulverizing and extrusion shearing disintegrating apparatus and the factor that affects disintegrating apparatus degradation rate and efficiency, find out to overcome and announce new technology shortcoming, realize and obviously surmount the technical scheme of the target of having announced new technology imagination.Relevant R&D work comprises:

(1) according to dynamics collision principle and solid deformation and pulverizing relative theory analysis, all granular solids materials all have the combination energy that can keep its solid shape constant.When only acting on external force on this material particles and giving the deformation energy of material particles and exceed the combination energy of material particles, material particles could be broken, is all just idle work otherwise external force does.Therefore, improving the degradation rate of pulverizer and the effective ways of operating efficiency should be that outer force intensity is brought up to the number of times that is enough to the degree of broken material particle and increases the effect of the material that is enough to broken material particle.Theory analysis and facts have proved in a large number, between rotor pin 6 and stator pin 5, gap is less, and pulverizer degradation rate is higher.Announced new technology attempt to be used in rotor pin 6 method that to arrange with tangential working face angle α be the inclined cut of 15 °~35 ° and the tangential working face of zigzag increase can broken material particle effective shock number of times, improve degradation rate, but because α angle is excessive and first sawtooth blocks, sawtooth touches less than material below, could not effectively achieve the goal.The present invention uses following technological means to overcome the shortcoming of announcing new technology, reach the object of raising equipment degradation rate: in the time that rotor pin 6 is installed, make the tangential working face 27 of rotor pin and taking rotor disk 8 axis centered by the tangent plane angle β on the face of cylinder (A cylinder 52) of line crossing with it be 5 °~20 °.

(2) present inventor is creatively according to the detection data analysis of model machine function test and pin abrasion test, not only find to announce the shortcoming of new technology stator pin 5 rapid wears, and recognized and announce new technology only taking rotor pin 6 wearing and tearing and the wearing and tearing of sawtooth quantity as judging that according to analysis pin service life is incomplete.Correct method should be rotor pin 6 and stator pin 5 take into account and taking wear extent as analyze foundation.Accordingly, we develop and overcome the method for announcing short shortcoming of new technology pin life-span and be: the tangential of pin wear member 12 and radially working face end a top width is respectively set than other sawtooththe special-shaped sawtooth of 51 at least large 2 times of tooth bottom width degree.If wear away 2mm as lifetime limitation analysis taking rotor pin 6 near stator pin 5 place's carbide alloy, because special-shaped sawtooth is 2 times of existing percussion grinder rotor pin 6 hard metal tip thickness, so be at least the twice of existing percussion grinder rotor pin the service life of pin in the present invention, if consider function and efficacy and the equal effect extending in 5 service lifes of stator pin of special-shaped sawtooth front sawtooth, these data at least will quadruple.

(3) analyze in theory, having extrusion shearing crushing function is a large advantage of having announced new technology.It has not only been started the direct extrusion shearing of rotor pin 6 with the high-speed motion material particles between rotor pin 6 and stator pin 5 and has reached the brand-new working method of pulverizing object, expand the disintegrating apparatus scope of application (can be used for pulverizing the toughness material such as plastics, rubber), and simple in structure according to the present invention, effective utilization rate of electrical height and nearly all solid material shear strength are the situation analysis judgements such as 1/2 left and right of compression strength, and high-speed extrusion shear pulverizer is most effective pulverizer.But as described in the background art, test data shows, having announced new technology, to do the effect that high-speed extrusion shear pulverizer uses also not ideal enough.According to model machine function test result, we analyze, when the running of high-speed extrusion shear pulverizer rotor, rotor pin 6 inclined cuts can be clamped and hold material particles and it is applied to extrusion shearing power together with the tangential working face of stator pin 5, also can apply and force its proal thrust material particles separately simultaneously.Evidence, within the specific limits, rotor pin 6 inclined cuts reduce with tangential working face angle, and the probability that pincers are held material particles increases (performance is that equipment degradation rate improves), and motive force reduces; Otherwise rotor pin 6 inclined cuts and tangential working face angleincrease, the probability that pincers are held material particles reduces, and motive force increases.Having announced new technology does the undesirable one of the main reasons of high-speed extrusion shear pulverizer effect and is rotor pin 6 inclined cuts and tangential working face angleexcessive, another main cause be the sawtooth that participates in comminution process and have an extrusion shearing crushing function very little.The present invention has overcome the shortcoming of announcing new technology; Research and develop successful model machine by the technical scheme after improving and do the function test detection data demonstration that high-speed extrusion shear pulverizer is used, its degradation rate is higher more than 50% than having announced new technology.

By dynamics collision principle and disintegrating apparatus principle Analysis, compared with clashing into space, several times at least greatly of the active forces that when rotor pin 6 and stator pin 5 are held in active force that material particles between the two applies and clash into than space pincers, material particles is subject to, even tens times; And apply all rotor pins 6 of each rotor pin 6(of active force) be and the fixing all-in-one-piece of rotor disk 8, wheel hub 9 and motor 10 rotors that the kinetic energy that each rotor pin 6 has and all these parts have the summation equivalence of kinetic energy.With the combination of any one material particles of any material can compared with, the kinetic energy that rotor pin 6 has is almost all infinitely-great.Therefore, it can be asserted that: for the solid material of all materials, as long as its granularity is greater than described minimum clearance L2, as long as pin is continuous, the present invention can both effectively pulverize it as high-speed extrusion shear pulverizer, and crushing material rate (pointing out the pulverized probability of machine material) and crush efficiency (characterizing the speed of comminuting matter) are far above similar size reduction machinery.The large advantage of the present invention one beyond doubt applied widely.

Need to illustrate especially: the present invention does high-speed extrusion shear pulverizer use, during especially for high strength materials such as processing ores, fast tens times than the percussion grinder of existing processing wheat of the rates of wear of pin, even tens times.So whether pin has sufficiently long service life is also to determine that can the present invention do the key condition that high-speed extrusion shear pulverizer uses.Long-term a large amount of practice detects data and shows, uses the corner angle part of the percussion grinder rotor pin hard metal tip of 5 years to wear away 1mm left and right in flour mill.Height and the tooth bottom width of having announced sawtooth on new technology pin wear member are all 1mm.Like this, by fast ten times of reckonings of the high-speed extrusion shear pulverizer pin rate of wear, announce sawtooth use on new technology rotor pin wear member and will polish for 6 months, only needed just polish for one month by 60 times of reckonings.Obviously, analyze by pin service life, announced new technology and can not work as high-speed extrusion shear pulverizer and use.The present invention arranges the special-shaped sawtooth of widening at top on pin can ensure 4~10 times of pin life-span raisings.Obviously, above-mentioned measure is enough to ensure that the present invention can do high-speed extrusion shear pulverizer and use.In addition, be the anti-wear performance best material analysis adopting in disintegrating apparatus up to now according to carbide alloy, by pulverizing the examination of equivalent amount material particles, the service life of consumable accessory of the present invention is also the longest.

(4) mainly clash into material particles by the radially smooth working face of rotor pin 6 with the motion of 60m/S linear velocity according to existing percussion grinder and just had appreciable crushing function analysis, impact disintegrating mill improves innovation should not ignore the effect that radially working face clashes into.Analyze by creativeness, inventor considers that being knocked material particles moves and take away part kinetic energy in smooth flat, can make impact strength and effect reduce, we rotor pin 6 and stator pin 5 major parts radially working face make standard zigzag into, and (this is also to slow down pin wearing and tearing to be all provided with a wide especially special-shaped sawtooth in top at both ends, the necessary means increasing the service life), evidence this measure can make degradation rate of the present invention and efficiency obviously improve.
