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

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.
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 driving of driving assembly, 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.
Inventors have found that as the rotor principle of windmill and helicopter, cross balancing wing in cylinder in face of air-flow,
Air-flow is converted into the driving moment of blade to the pressure of cross balancing wing blade, driving blade rotation, due to the constraint of elastic rod,
Cross balancing wing blade can only make the reciprocally swinging of certain amplitude along rotation round plane, generate periodically to draw elastic rod
Tensile deformation, the mechanical oscillation that elastic rod generates are transmitted to the circumference sieve cage at connection elastic rod both ends in turn, can remove and block
The rubber powder of waste tire particle of sieve pore mesh, to improve the efficiency of circumference sieve cage sorting rubber powder, the noise of vibration is enclosed in
In cylinder, reduce the discharge of noise pollution.
Inventors have found that in view of composite factors such as energy consumption, cost, purposes, the performances of the production of waste tire fine glue powder,
General charging is that the blob of viscose of 5 mesh is processed as the waste tire fine glue powder of two ranks of 38 mesh and 60 mesh, corresponding design fine-grade
Two kinds of screening plants of cage and its storage device are sieved with fine grade circumference, the 38 mesh grade waste tire fine glue powders for sieving acquisition are made
For the primary raw material of high-quality tyre reclaimed rubber, 60 mesh grade waste tire fine glue powders substitute virgin rubber directly as additive.
Inventors have found that waste tire fine rubber powder finished product accumulate storage during, if contain certain moisture, pole
Easily become the excellent procreation carrier of microbial cells, the metabolite that these microbial cells generate during fermentation is such as
H2、CH4And heat just makes rubber powder deposit not easy heat radiation, accumulation of heat to certain journey since rubber powder is hot poor conductor
Degree, can all cause rubber powder finished product accumulation of heat spontaneous combustion in lower flash-point, this is also that rubber powder deposit stores also can at normal temperature
The main reason for spontaneous combustion.The approach of solution is nothing but first is that reduce oxygen amount, second is that radiating and cooling, third is that killing thallus.And rubber powder
To produce in enormous quantities, it is difficult to store by large-scale this mode of nitrogen charging storage tank due to cost, and production site is limited
It is also not easy to implement by the method for the increasing heat radiation area that tiles, so production plant is generally used the mode of heap height storage, because
This solve the problems, such as the key of rubber powder finished product heap normal temperature storage process accumulation of heat spontaneous combustion should be by reduce rubber powder contained by moisture,
The condition of cutting microorganism fungus kind procreation mentions so that microorganism fungus kind fermentating metabolism be avoided to decomposite the combustible of small-molecular-weight
The security level of high fire-fighting.
Inventors have found that microbial cells are ubiquitous in the environment, can effectively be killed using steam-heated mode
Microbial cells inhibit its procreation growth.Vapor is in gaseous state and when the gas solid separation of rubber powder granule is relatively cooled to water simultaneously
Solid-liquor separation difficulty it is much smaller, therefore this case use pulse airbag separate vapour, trap rubber powder particles technology
Scheme devises spiral step blade, the rubber powder particles that steam carries in combination with cyclonic separation, the technology of sedimentation separation
It constantly loses energy with the collision of spiral step blade and cylinder inboard wall friction during along cylinder inboard wall spiral and falls
Rotary case, and steam is discharged along the channel of spiral step blade through filter bag, due to the cyclonic separation in cylinder, spiral step blade
Most of rubber powder particles are intercepted with sedimentation separation, it is substantially that filter bag works that a small amount of rubber powder particles are intercepted by filter bag
The time interval of duration, blowback extends, and the frequency that pulse is vented the starting blowback of blowback control system reduces, to reach high
Imitate the technical process of separate vapour and rubber powder granule.The spiral step blade of central axis is mounted on during rotation, by portion
The rubber powder particles for being trapped in spiral step blade are divided to be transported to rotary case.
Inventors have found that by water vapour complete waste tire fine rubber powder production process in conveying, sterilizing, separation,
The technical process such as sorting, protection are undoubtedly ideal, pneumatic conveying load of the vapor as waste tire fine rubber powder
The modes such as the more mechanical conveying of body reduce cost, energy conservation, automation, reduce the advantages of labor intensity；Vapor is as waste and old wheel
The sterile medium of tire fine rubber powder can effectively kill microbial cells, inhibit its procreation growth, microorganism fungus kind is avoided to send out
Ferment metabolic breakdown goes out the combustible of small-molecular-weight, improves the security level of fire-fighting, solves rubber powder deposit and stores at normal temperature
The problem of spontaneous combustion；It is relatively cooling through sedimentation, whirlwind, filter bag completion gas solid separation process that vapor carries waste tire fine rubber powder
It is much easier for the solid-liquor separation of water, it reduces as far as possible and moisture necessary to microorganism grows is provided；Vapor carries waste and old
The gas solid separation process of tire fine rubber powder also helps rubber powder particulate matter to complete the process sorted through different sieve pores；Vapor
As the protection medium of waste tire fine rubber powder, makes its confined space conveying low in oxygen amount, prevent its burning even quick-fried
Combustion.
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, the conveying in waste tire fine rubber powder production process is completed by water vapour, sterilizing, separation, is divided
