Description
Technical field
The present invention relates to a kind of hammer crusher and breaking method thereof, can be extensive use of in industries such as feed, grain, chemical industry, food, pharmacy, plastics.
Background technology
Present existing pulverizer kind is a lot.Usually by sieve, hammer leaf, rotor, body, compositions such as motor, its operation principle is: earlier by the driven by motor rotor, make the rotation of rotor and epitrochanterian hammer leaf, after material was subjected to the hammer leaf bump, qualified powder was discharged from sieve aperture.
Usually, the granularity characteristics of pulverizing from pulverizer can be divided into pulverizer two classes: common pulverizer and ultrafine crusher.Common pulverizer generally is used for the material of fineness below 40 orders to be pulverized, and material is through the crushing screening net, the finished product granularity is good, but for requiring grinding particle size at 40 order to 60 orders and more than 60 orders, stifled easily sieve, material is excessively pulverized, the material temperature rise.Ultrafine crusher generally is used for the above material of 60 orders to be pulverized, and does not generally adopt screen cloth, and adopts selection by winnowing, and according to the proportion of material, non-particulate diameter factor such as surface configuration is carried out selection by winnowing, and the finished product granularity can not guarantee.
In addition, can also classify from the appearance structure of pulverizer.Divide from the kind of drive, have motor directly to lean on, belt transmission also has horizontal shaft type, and vertical shaft type is also arranged.Classify from feeding manner, its top feed is arranged, the charging of oblique top portion, axial admission.The chieftain classifies from pulverizer, and hammer slice type is arranged, pawl formula, emery disc formula, nitre pillar, roll-type or the like.
Although these pulverizer styles have difference, crush efficiency is identical substantially.People also improve crush efficiency in several ways, and as the secondary disintegrating process, fish scale hole sizer plate, pulverizer air draft system improve, and change feed entrance point or the like, though obtained certain effect, have all failed important breakthrough.
Up-to-date patented product is all attempted to have breakthrough on crush efficiency, as the Chinese patent publication number is the patented technology of CN1153083, its mentality of designing is pulverizing chamber to be hung and installs vibrating motor, make screen cloth be in dither, attempt to keep screen cloth unimpeded, make that pulverizing qualified material in time goes out screen cloth.But when 80 orders were above, and the material of the high fiber of high grease was when pulverizing at grinding particle size, still old stifled sieve phenomenon, and cisco unity malfunction, when 80 orders were following, a finished product degree was partially slightly.Because the existence of vibration factor causes the variation and the internal structure rapid wear in hammer sieve gap, has a strong impact on the stability of equipment, does not embody original design idea in actual production is used.This technology has just been alleviated the phenomenon of stifled sieve to a certain extent, but the still not solution of the basic reason of stifled sieve, table does not effect a permanent cure.
In the prior art: have second material flow of utilizing first material flow and not having component motion to clash into, also have second material flow of utilizing first material flow and having the relative motion component to clash into, have the component motion that utilizes first material flow to drive second material flow mutually mutually.But for the material with high tenacity, allow two technology that material flow is clashed into mutually, collision time prolongs, and crush efficiency reduces.
As China Patent No. is the patented product of ZL03820653.6, its mentality of designing is that second logistics that will have component motion joins in the path of first logistics, second logistics and first logistics are clashed into mutually, owing to be same raw material all, if what pulverize is that its efficient of the high material of toughness is extremely low, only suitable brittle material; The feeding of second logistics becomes vertical angle with first material flow, and second logistics and first logistics bump is the point of the superiors just, not on rotor axial with the first logistics multi point impact.Though its mentality of designing has breakthrough, when the stronger material of toughness was pulverized, the collision time between material and the material prolonged, and actual crush efficiency does not still have significant improvement.
How to make a pulverizer, under adverse factor conditions such as eliminating screen cloth vibration, can pulverize carse, medium and small material simultaneously, and thoroughly the stifled sieve of solution phenomenon becomes the technical barrier that urgent need will solve.
Technology in the past can satisfy the problem that the granularity qualified material in time goes out sieve, crucially still is how to solve material and gets lodged in problem on the screen cloth not being crushed to when setting granularity.The method that allows screen cloth vibrate is worthless from the stabilization of equipment performance angle, therefore will shorten the pulverizing time, and make material be crushed to the granularity of setting rapidly, stifled sieve phenomenon is disappeared, improve crush efficiency, so research direction of the present invention is how to increase the hammering dynamics.
And existing pulverizer equipment, because the pulverizing overlong time of material in pulverizer makes the underproof material of granularity be embedded in the sieve aperture, sieve aperture is blocked, efficient reduces.Through experiment, increase root diameter for existing pulverizer, use high-speed electric expreess locomotive (2970 rev/mins), increase the tangential velocity of hammer leaf, just increase the hammering dynamics, stifled sieve phenomenon is alleviated even disappear (0.35MM screen cloth).Illustrate that the hammering dynamics is crucial.But in actual production was used, the such rotating speed and the diameter of rotor be excess loads to bearing, stable extreme difference.
So simply increase the method for root diameter, also be infeasible in fact in actual production.
Material can be represented by following momentum theorem formula by the dynamics of hammer leaf hammering:
F＝(MV-mv)/t
Wherein, F=hammering dynamics, M=hammer leaf quality, m=quality of material, V=hammer leaf speed, v=material speed, t=percussion time (time of contact of material and hammer leaf).
In the above-mentioned formula, the T value is the time of contact of material and hammer leaf, if pulverize same material, the t value is the same.If adopt the mutual bump of two material flow, this T value is skimble-skamble for hammer leaf.If will improve F, will seek the maximization of (MV-mv).
Through labor as can be known, M and m are definite values, and that important solution is V and v.
V is relevant with the motor speed and the root diameter of pulverizer, by the technology of now making, has only from root diameter and considers.Root diameter strengthens, and rotor volume weight has also just strengthened comparatively speaking, all has been the limit of load to bearing and motor, can not promote the use of in actual production.
V is relevant with the speed of material, if material speed is a negative value, that is for V, and the limit of making just can break through.In the disclosed now equipment, many kind feeding modes are arranged, majority is the feeding of 0 value, and the negative value feeding is also arranged.As China Patent No. is the patented product of ZL03820653.6, v is a negative value, but it just utilizes second material flow and first material flow bump with component motion, and this bump is the point in the first material flow the superiors, the mutual bump of material itself only is suitable for more crisp material, and just v is that negative value will have very big discount.For hammer leaf speed V, this v is still 0.
Through aforesaid analysis, how to allow v be the negative value maximization and be effective, material is relative as far as possible with the direction of motion of hammer leaf, how to allow the v be the quantity maximization of negative value material flow, and just material maximizes the emphasis that becomes research with the quantity that contacts of hammer leaf.
Simultaneously, it should be noted that the mutual bump that avoid between the material flow, for hammer leaf, such bump is invalid.

The specific embodiment
Shown in Fig. 1 a, 1b, 1c, be respectively the axial front view and the left and right side view of pulverizer of the present invention.Pulverizer of the present invention has a base 12, is installed with a frame 11 on the base 12, and the top of frame 11 is provided with two charging aperture 13a, 13b, and the inside of frame 11 is formed with an accommodation space 10, two charging aperture 13a, 13b and is connected with this accommodation space 10.Two rotor 22a, 22b are arranged in this accommodation space 10 and lay respectively at the below of two charging aperture 13a, 13b, the circumference of rotor 22a is provided with four groups of hammer leaf 23a, also be provided with four groups of hammer leaf 23b on the circumference of rotor 22b, these hammer leaves 23a, 23b are equidistant spaced apart on the circumference of rotor 22a, 22b, also can distribute arbitrarily, the former is preferable selection, and each epitrochanterian hammer leaf number is at least three, has chosen four in the present embodiment.Two rotor 22a, 22b load onto main shaft 21a, 21b respectively, two motor 5a, 5b drive main shaft 21a, 21b rotation respectively by linkage 6a, 6b, rotate at a high speed thereby drive rotor 22a, 22b, make the hammer leaf 23a, the 23b that are arranged on rotor 22a, the 22b around main shaft 21a, 21b also rotation at a high speed.One guiding device 20 passes the accommodation space 10 at frame 11 middle parts and is arranged at two rotor 22a, between the 22b, the two ends of guiding device 20 are fixed on accommodation space 10 frame 11 outward by fastener 28, be convenient to install and change, the stage casing of guiding device 20 then is divided into two pulverizing chamber 31a with the accommodation space 10 in the frame 11,31b (hereinafter referred to as the first pulverizing chamber 31a and the second pulverizing chamber 31b), two pulverizing chamber 31a, 31b is two spaces on the relative meaning, be not definitely independently, because guiding device 20 has just intercepted the mid portion of accommodation space 10, so pulverizing chamber 31a, 31b still is connected in the upper and lower of guiding device 20.The bottom margin that screen cloth 24a, 24b are separately positioned in pulverizing chamber 31a, the 31b extends on the lateral edges of charging aperture 13a, 13b always, screen cloth 24a fixes by upper screen cloth fixture 26a and lower screen cloth fixture 25a, screen cloth 24b fixes by upper screen cloth fixture 26b and lower screen cloth fixture 25b, in pulverizer, adopt large- area screen cloth 24a, 24b, can avoid material excessively to pulverize, change the pulverized particles size distribution curve.In addition, top edge in two pulverizing chamber 31a, the 31b between two charging aperture 13a, 13b also is respectively arranged with two top tooth plate 27a, 27b, can be rebounded back after last and pulverized again again in pulverizing chamber 31a, the 31b when hammer leaf 23a, 23b that material is rotated at a high speed strike tooth plate 27a, 27b, further be improved crush efficiency.This shows that pulverizer of the present invention is the structural system that adopts two main shafts, bi-motor and two pulverizing chamber, two rotors adopt same size, identical rotating speed and direction of rotation.
The pulverizer operation principle as shown in Figure 2, material flow M1, M2 enter accommodation space 10 in the pulverizer by two charging aperture 13a, the 13b on pulverizer top respectively, material flow M1 enters the hammer leaf 23a on high speed rotor rotated 22a in the first pulverizing chamber 31a and pulverizes, and material flow M2 enters the hammer leaf 23b on high speed rotor rotated 22b in the second pulverizing chamber 31b and pulverizes.In the first pulverizing chamber 31a, pulverize qualified material and go out sieve by screen cloth 24a, do not pulverize the qualified material flow M1-1 that goes out to sieve under the effect of guiding device 20, the overwhelming majority enters the second pulverizing chamber 31b, by the hammer leaf 23b of rotation pulverizing at a high speed in the second pulverizing chamber 31b, material flow M1-1 is relative with the direction of motion of hammer leaf 23b or relative substantially, component motion is also equal substantially, then material flow M1-1 is pulverized in the second pulverizing chamber 31b with material flow M2, qualified material goes out sieve through screen cloth 24b, and the not qualified material that goes out to sieve has formed material flow M2-1 again.Material flow M2-1 is under the effect of guiding device 20, and the overwhelming majority enters the first pulverizing chamber 31a again, is pulverized once more by the hammer leaf 23a that rotates at a high speed in the first pulverizing chamber 31a, and its direction of motion is relative with hammer leaf 23a or relative substantially, and component motion is also equal substantially.Material flow M2-1 is pulverized at the first pulverizing chamber 31a, and qualified material goes out sieve through screen cloth 24a, and the not qualified material flow M2-1 that goes out to sieve has formed material flow M1-1 again with initial material flow M1, enters once more in the second pulverizing chamber 31b and is pulverized.Like this, the work of pulverizer negative pressure, qualified material in time goes out sieve, and the circulation that not qualified material goes round and begins again in pulverizer is pulverized.
In two pulverizing chamber 31a, 31b, go out the sieve ability the poorest be at upper space, therefore be provided with tooth plate 27a, 27b, this can the increment materials flow in the bounce-back and the friction of pulverizing chamber inside, can be rebounded back after last and pulverized again again in pulverizing chamber 31a, the 31b when hammer leaf 23a, 23b that material flow is rotated at a high speed strike tooth plate 27a, the 27b of pulverizing chamber 31a, 31b upper space, thereby be improved crush efficiency.Large-area screen designs is adopted in position in pulverizing chamber 31a, the 31b best discharging in bottom, and the area of screen cloth 24a, 24b has increased, thereby has improved output.
As above in the narration, material flow of the present invention is relative or relative substantially with the direction of motion of hammer leaf in knockout process, component motion is also equal substantially, pulverized by hammer leaf 23a in the first pulverizing chamber 31a about being explained as follows of this component motion: material flow M1, hammer leaf 23a is in the rich main shaft 21a high speed rotation status, material flow M1 should be to move along the move tangential direction of circumference of hammer leaf 23a after crushed, but because the effect of screen cloth 24a, qualified material flows out screen cloth 24a, the not qualified material flow that goes out to sieve is the track along screen cloth 24a, has formed the material ring of circular motion between hammer leaf 23a and screen cloth 24a.They have the amount of exercise that approximates hammer leaf 23a tangential velocity.When the not qualified material flow M1-1 that goes out to sieve arrives the upper area of guiding device 20, use V
1Represent the speed when this material flow M1-1 enters the second pulverizing chamber 31b, this speed V1 and the hammer leaf 23b tangential velocity V that is about to clash into mutually
2Be relatively or relative substantially, represent the hammering dynamics with F, so according to momentum theorem F=(MV
2-mV
1)/t, wherein, M is the quality of hammer leaf 23a, and m is the quality of material flow M1-1, and t is their collision time, because the tangential velocity V of hammer leaf 23b
2Speed V when entering the second pulverizing chamber 31b with material flow M1-1
1Direction opposite, so V
1Be negative value in formula, thus the hammering dynamics be actually F=(| MV
2|+| mV
1|)/t, this shows that the hammering dynamics that produces when material flow M1-1 and hammer leaf 23b collision is sizable.In like manner, when material flow M2-1 enters the first pulverizing chamber 31a and the collide hammering dynamics that produces of hammer leaf 23a also very big.The circulation that goes round and begins again in the first pulverizing chamber 31a and the second pulverizing chamber 31b is like this pulverized and material flow can be pulverized fully, the hammering dynamics of hammer leaf when comminuting matter increases greatly, broken through the technical restriction of traditional fabrication, make stifled sieve phenomenon disappear, reach good crushing effect and greatly improved crush efficiency.
Fig. 3 is the schematic perspective view of guiding device, guiding device 20 is plates of a similar cuboid, its cross section is the parallel four limit row of both sides inner concavity, it passes the accommodation space 10 at frame 11 middle parts and is arranged at two rotor 22a, between the 22b, fastener 28 is passed through (such as bolt in two ends, screw etc.) be fixed on accommodation space 10 frame 11 outward, the stage casing then is divided into the first pulverizing chamber 31a and the second pulverizing chamber 31b with the accommodation space 10 in the frame 11, guiding device 20 has intercepted the mid portion of accommodation space 10, two pulverizing chamber 31a, the upper and lower of 31b still is connected.Therefore guiding device 20 can play guiding and shunting action to material flow.This guide effect is that the not qualified material that goes out to sieve is imported adjacent pulverizing chamber, make the direction of motion of material flow relative with the direction of motion of the hammer leaf that will touch or relative substantially, guiding device fundamental diagram as Fig. 4, material flow M1 enters the second pulverizing chamber 31b, the not qualified material flow M1-1 that goes out to sieve is under the effect of guiding device 20, and the overwhelming majority enters the second pulverizing chamber 31b; Same material flow M2-1 also enters the first pulverizing chamber 31a under the effect of guiding device 20, relative with the direction of motion of the hammer leaf that will contact or relative substantially; For the hammering dynamics of hammer leaf, amount of exercise relative or basic direction of relative movement is the most effective.And this shunting action is meant material flow is separated substantially with hammer leaf.In single pulverizing chamber, the not qualified material flow that goes out to sieve is the direction of motion along with hammer leaf, at the peripheral moving ring bed of material that forms of hammer leaf, generally is in beyond the outer 2mm of hammer leaf.Guiding device 20 is crucial with the distance of hammer leaf 23a, 23b, and hammer leaf 23a, 23b carry out circular motion around main shaft 21a, 21b, outside its outside about 2mm material flow is arranged.In the first pulverizing chamber 31a, the not qualified material M1-1 that goes out sieve along with hammer leaf 23a when moving to the some 20-1 of guiding device 20, the material flow M1-1 of the overwhelming majority will enter the second pulverizing chamber 31b.The distance of the point 20-1 of the hammer leaf 23a of the first pulverizing chamber 31a and guiding device 20 is controlled in the 2mm, makes the amount maximization of the material flow M1-1 that enters the second pulverizing chamber 31b, and avoids contacting of hammer leaf 23a and guiding device 20.In the second pulverizing chamber 31b, not qualified material flow M2-1 is along with hammer leaf 23b equally, and when moving to the some 20-2 of guiding device 20, the material flow M2-1 of the overwhelming majority will enter the first pulverizing chamber 31a.The distance of the point 20-2 of the hammer leaf 23b of the second pulverizing chamber 31b and guiding device 20 is controlled in about 2mm, makes the amount maximization of the material flow M2-1 that enters the first pulverizing chamber 31a, and avoids contacting of hammer leaf 23b and guiding device 20.Shunting action has been avoided the bump between two material flow M1-1 and the M2-1, thereby has guaranteed validity and the effective hammering quantity of the component motion of material flow to hammer leaf hammering dynamics.Guiding device adopts tungsten carbide spot welding to handle, and makes guiding device prolong for 20 service lifes.
