The technical solution that the prior art 1 proposes be use four kinds with fix a cutting tool (Disintegrating knife in feed inlet, nog plate, grinding roller,
Mill, bull ring) it is crushed the method production rubber powder being sieved with sieve, rubber powder is sorted the disadvantage is that energy consumption is high using the method for sieve sieving
The easily stifled efficiency of separation of (vibrating screen), sieve pore is low, and is arranged repeatedly to be crushed and has also proved this lower problem of the efficiency of separation, has broken
The rubber powder of broken qualification, which can not sort out, to be continued to be crushed, and on the one hand increases energy consumption, on the other hand reduces the quality of rubber powder, from aobvious
Micro mirror observation rubber powder granule can find that the vulcanized rubber powder being crushed through mechanical shearing has many brachyplast beams, alternatively virgin rubber
Filler is in use, these brachyplast beams can be good at winding grafting with rubber molecular chain and merge, and when being repeatedly machined, due to
Frictional heat generation the charing of rubber powder incipient scorch will occur without reason cooling well to asking of declining of quality index after the vulcanization of rubber
Topic；The prior art 2 is conveyed into waste tire block in bistrique by the way of screw extruding (auger) and carries out Mechanical Crushing, bistrique
It is made of rotary bistrique and stationary bistrique, the maximum defect of this technical solution is how to solve rubber powder frictional heat generation not cool down well
There is the problem of incipient scorch charing is to reduce rubber performance, due to process the rubber powder of 20~120 mesh, rotary bistrique and stationary bistrique it
Between gap very little, waste tire block cannot be introduced into, it has to be forced by the way of screw extruding, must in milling process
So rubber powder being caused to gather a large amount of heat can not cool down, so documents 2 are using circulating water, air-cooled two kinds of sides in bistrique
Formula attempts to cool down, but both modes are difficult to reach cooling effect, circulating water technical solution leading due to rubber in bistrique
Hot coefficient is lower, by way of water-bistrique-micelle heat transfer, heat exchange area it is limited, the efficiency of heat exchange is lower, can not
Rubber powder is rubbed, bistrique shearing and the amount of heat gathered is taken away in time；The technical solution of air cooling is due to auger and mill
The reason of head sealing can not form convection current and not have effect naturally (induced draught system in 2 specification of documents also only play
The automatic effect for inhaling hair).
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of waste tire fine rubber powder steam for preparing to protect
The application method of mill is protected, it is characterized in that:
Step 1 first distributes bowl assembly, separator assembly, grinding assembly with 105 DEG C of steam blowings before the work that feeds intake, at this time
Electric butterfly valve is opened, annular header is in an off state, and steam enters from steam inlet I, steam inlet II, through enturi tube,
Header emptying discharge.
Step 2, after purging, the pallet for actively grinding comb component rotates under the drive of the drive, by adjusting bullet
Spring loading device, grinding roller arm impose suitable grinding pressure to mill, and micelle is fed from center material blanking tube, comb through mill, taper
It shears and cuts with scissors on the broken mill bowl for falling on rotation, micelle is under the influence of centrifugal force, mobile to mill bowl periphery, when by grinding bowl and mill
Between when, be ground into powder, the rubber powder granule worn into continues to be displaced outwardly, last to overflow along mill bowl periphery；And mill is justified
All tangent direction friction power drives are rotated around own central axis line, the passive mill for grinding three groups of grinding rollers of comb component shearing-crushing blob of viscose two-by-two,
There is a bevel angle between two groups of mills, can be crushed being sent into after blob of viscose shearing-crushing not of uniform size between mill bowl and mill；
Spatial summation micelle to prevent three groups of grinding roller heads from can not grind leads to dead angle, devises taper comb, the outer cone that taper is combed
Face design has ribbon sword to surround, and cleavable larger blob of viscose while is sent between mill bowl and mill and is crushed, and can be used as
The baffle of venthole prevents micelle from blocking venthole.
Step 3 is sent into steam phase combination, carrying rubber powder by the steam in taper comb through venthole purging and out of skirt
Particle is risen along body spiral inner wall from bottom to top by mill bowl periphery, is mounted in heavier coarse rubber powder granule collision point
It is refaced from kinetic energy return mill bowl is lost after the oblique liner plate of body bottom；Lighter tiny rubber powder is by oblique liner plate along separator body
What wall spiral entered separator body top is folded to door component, and being folded to blade makes vapour powder mixture generate rotation in inner cone
Stream, the underproof rubber powder of fineness return to mill bowl grinding, the rubber powder warp of fineness qualification by separation from eddy flow along inner cone inner wall
Header is inputted by Venturi tube, the angle that bar link chain adjustment is folded to blade can be stirred by regulation handle, and according to the speed of eddy flow
Degree obtains the final finished fineness of rubber powder.
Step 4 is mingled in the metal impurities inputted in rubber powder or other impurity for being difficult to grind and overflows from mill bowl edge
When, because its self weight falls into skirt, it is mounted on the screeding device on pallet and rotated, these sundries are swept into impurity row
Outlet.
Inventors have found that comparing room temperature mechanical shearing broken rubber powder granule and low temperature cold if examined with microscope
Freezing broken rubber powder granule can find, the vulcanized rubber powder being crushed through mechanical shearing has many brachyplast beams, what cryogenic freezing was crushed
Then surface is very smooth for micelle, according to the 8th fascicle page 570 of " rubber industry handbook ", Yang Shungen, Bai Zhongyuan chief editor, chemical industry
Publishing house, the guide of the 1st edition curability test method in relation to half finished rubber in 1992, above two rubber powder granule substitution
Sulfide film sample testing tensile strength is made as filler addition in virgin rubber, compares test result and learns, in addition number one
In the case where cause, even the broken mesh number for the rubber powder granule that addition cryogenic freezing is crushed is lower (such as 100 mesh), also it is not so good as to add
The tensile strength for adding room temperature mechanical shearing to be crushed the vulcanized rubber of the bigger rubber powder granule (such as 60 mesh) of mesh number is high, therefore low temperature
Freezing crushing method is not promoted well.
Inventors have found that if examining the difference processing compared using room temperature mechanical shearing breaking method with microscope
Same mesh number rubber powder granule can be found under time and Different Cooling Conditions, and process time is short short with the vulcanized rubber powder of good cooling results
Branch Shu Mingxian is more, because machining time is long, does not have the reason cooled down well vulcanized rubber powder even occur after frictional heat generation
The phenomenon that incipient scorch carbonizes, to the problem of quality index declines occur after the vulcanization of rubber, and with potassium permanganate stain-microphotograph
The experimental result of method observation rubber powder granule and virgin rubber dispersion mixing also illustrates that brachyplast beam can help rubber powder granule and virgin rubber rubber
Strand winding grafting complexing, therefore the key technology of waste tire room temperature shearing-crushing is broken to reach fast after series requirement
Speed sorts and takes away in time heat or effectively protect that friction generates.
Inventors have found that if rubber powder of waste tire loss will cause environmental pollution in surrounding air, so production
Process must be run in obturator, therefore can be to avoid mechanical mode of movement (such as vibrating screen) by the way of pneumatic conveying
The problem of complicated dynamic sealing device, and more mechanical mode of movement need to be designed, since the frictional force that pneumatic conveying need to overcome is less,
Energy consumption is lower, reduces production cost, makes it possible industrialized production.
Inventors have found that since waste tire rubber has the characteristics that elastic deformation is big, frictional force is big, according to its elastic shape
The breaking method that the characteristics of becoming larger is designed be shearing, for as far as possible reduce cutter mechanical energy be changed into rubber elastic potential energy and
Cause to flog a dead horse, the gap for the shearing tool being commonly designed is smaller, and the big feature of its frictional force inevitably results in mechanical shear
Cut through it is broken during easily heat and the not easy heat radiation in narrow space, and the vulcanized rubber powder bumps crushed through mechanical shearing are not
It is flat and have brachyplast, it is easy to gather heat-accumulation combustion of uniting and rubber powder is caused to burn charing, it is therefore necessary to means are effectively protected in use,
First is that cooling, second is that reducing oxygen amount.If using the means usually to cool down, due to the not limitation of easy heat radiation in narrow space,
Heat transfer efficiency is undesirable, and higher temperature makes cured waste tire rubber generate plastic extension, i.e. strand spacing
Becoming larger causes intermolecular force to reduce, and becomes easy cutting, to make production efficiency improve, such as usually used at present
Double-roll crusher in practice it is found that roller temperature reaches 90~100 DEG C of rubber powder production efficiency highest.Therefore this case uses
Pneumatic conveying carrier and protective agent of 105 DEG C of water vapours as rubber powder, the air-flow that purges steam at a high speed can disperse rubber powder solution in time
Certainly its problem of adhering to of uniting provides necessary condition for sorting；Steam heating temperature is stably and controllable simultaneously makes waste tire rubber
It is easy cutting and crushing；Furthermore steam is a kind of protection medium well, rubber powder of waste tire can be effectively prevented gather to unite
Heat-accumulation combustion causes rubber powder to burn charing.Therefore rubber powder conveying, protection, heat preservation, sorting, separation are completed as medium using steam
Etc. production processes be undoubtedly it is ideal.
Inventors have found that the shearing tool designed for rubber powder of waste tire generally there are two types of form, move-stationary knife tool and
Dynamic-cutter moves-cutter only small part blade work on a time point of work, and working efficiency is lower, but rubber powder
It can be discharged from cutter, create conditions for sorting process in next step in time；The usually whole blades of dynamic-stationary knife tool are all working, work
It is higher to make efficiency, but radiates with regard to becoming insoluble problem, and rubber powder can not be discharged from cutter in time, to divide in next step
It is more difficult to pick process.The advantages of cutter of this case design combines above two cutter, i.e., actively grind comb component and passive grinding roller
Component, actively grinding comb component is moving knife, and passive grinding roller component is stationary knife, and passive grinding roller component includes three groups of plane included angle 120o
Grinding roller, when work, actively grind the rotation of comb component, and the frictional force that cutting waste tire rubber generates drives three groups of grinding rollers rotations, just goes out
Existing three groups of grinding roller working face, that is, mills are mutually cut and mill is mutually cut with working face mill bowl, the taper comb actively ground in comb component
The operating condition cut, to solve the problems, such as working efficiency and in time sorting.Mill is cone disc, conical surface sword in specific design scheme
It is the trapezoidal roll flute of 7~9o that portion's design, which has helix angle, and trapezoidal roll flute is along the uniform Boulez of circular conical surface；Actively grinding comb component includes mill
Bowl, pallet, taper are combed, mill bowl face be designed as smooth flat or design to have the circumferentially uniform Boulez helix angle in face be 7~9o's
Trapezoidal roll flute, it is hollow structure that taper, which is combed, and inner wall design has venthole, and outer conical surface design has ribbon sword to surround.When work
It actively grinds comb component to rotate under the drive of the drive, micelle is fed from center material blanking tube, and combing through mill, taper, it is broken to shear hinge
It falling on the mill bowl of rotation, micelle is under the influence of centrifugal force, mobile to mill bowl periphery, when by between mill bowl and mill,
It is ground into powder, the rubber powder granule worn into continues to be displaced outwardly, last to overflow along mill bowl periphery；And mill is tangentially rubbed by circumference
It wipes power drive to rotate around own central axis line, three groups of mills shearing-crushing blob of viscose two-by-two, has a bevel angle between two groups of mills, it can
It is crushed being sent into after biggish blob of viscose shearing-crushing between mill bowl and mill, grinding roller imposes conjunction using external spring charging device
Suitable grinding pressure；Spatial summation micelle to prevent three groups of grinding roller heads from can not grind leads to dead angle, devises taper comb, cone
The outer conical surface design that shape is combed has ribbon sword to surround, and cleavable larger blob of viscose while is sent between mill bowl and mill and breaks
It is broken, and can be used as the baffle of venthole, prevent micelle from blocking venthole, by taper comb in purge steam through venthole and from skirt
It is sent into steam phase in seat to combine, carries rubber powder granule and is risen from bottom to top along body spiral inner wall by mill bowl periphery, it is heavier
It is mounted on after the oblique liner plate of separator body bottom to lose kinetic energy and return to mill bowl in coarse rubber powder granule collision and reface；Lighter is thin
Small rubber powder is folded to door component along what separator body spiral inner wall ascended into separator body top by oblique liner plate, and being folded to blade makes
Vapour powder mixture generates eddy flow in inner cone, and the underproof rubber powder of fineness is returned from eddy flow by separation along inner cone inner wall
Bowl grinding is ground, the rubber powder of fineness qualification inputs header via Venturi tube and electric butterfly valve, is folded to the angle of blade according to eddy flow
Speed and rubber powder final finished fineness it is adjustable；Be mingled in the metal impurities inputted in rubber powder or it is other be difficult to grind it is miscellaneous
When matter is overflowed from mill bowl edge, because its self weight falls into skirt, it is mounted on the screeding device on pallet and rotated, this
A little sundries are swept into impurity outlet.
Compared with the existing technology, the present invention, which at least contains, has the advantage that first, in conjunction with the dynamic-stationary knife tool and dynamic-of the prior art
Comb component and passive grinding roller component are actively ground in the advantages of two kinds of cutters of cutter, design, and actively grinding comb component is moving knife, passive to grind
Roll assembly is stationary knife, and passive grinding roller component includes three groups of grinding rollers of plane included angle 120o, and when work actively grinds the rotation of comb component, is cut
The frictional force for cutting waste tire rubber generation drives three groups of grinding roller rotations, occurs as soon as three groups of i.e. mills of grinding roller working face and mutually cuts
Grind bowl with the working face actively grind in comb component with mill, the operating condition that taper comb is mutually cut, thus solve working efficiency and and
When the problem of sorting；Second, rubber powder of waste tire production process is run in obturator, is completed using steam as medium
