Description
Technical field
The utility model relates to a kind of rubber manufacturing machinery component, particularly relates to a kind of waste Crumb rubber crushing device mill.
Background technology
Waste rubber crusher is one of capital equipment of rubber powder production.At present, pulverizer mainly roller pulverizer and the various dry pan that rubber powder uses is produced.The major defect of roller pulverizer is that efficiency is low, energy consumption is large.The abradant surface of plane mill pulverizer is plane, rotating speed one timing, and by mill center to mill edge, linear velocity is increasing, weares and teares also increasing, can not keep flatness of the response for a long time, more difficult reparation after card wearing and tearing.Therefore improve the design of mill structure, for the particle size and its distribution improving rubber powder, improve crush efficiency, reduce energy consumption and have great importance.
Summary of the invention
The purpose of this utility model is to provide a kind of waste Crumb rubber crushing device mill, and the movable grinding disc male cone (strobilus masculinus) of this device mill adopts tapered convergence thread, and fixed millstone inner conical surface adopts straight radial shape rake tooth; Tapered convergence thread contributes to travelling forward of sizing material, reduces energy consumption.It is large that area pulverized by radial rake tooth, contributes to the abundant pulverizing of sizing material.
The purpose of this utility model is achieved through the following technical solutions:
A kind of waste Crumb rubber crushing device mill, described device mill comprises movable grinding disc and fixed millstone, and working face is made up of movable grinding disc and fixed millstone, and the gap in two mill faces is reduced to small end gradually by large end, the large end of mill adopts wider teeth groove and dark tooth, and mill small end adopts narrower teeth groove and shallow tooth; Movable grinding disc male cone (strobilus masculinus) adopts tapered convergence thread, and fixed millstone inner conical surface adopts straight radial shape rake tooth; Gap between dynamic fixed millstone is adjustable shape, and movable grinding disc cone angle adjustable range is 35 ° ~ 55 °.
Described a kind of waste Crumb rubber crushing device mill, the crushing tooth cross section of described fixed millstone is triangle, and tooth depth is 3 ~ 0 mm by large scope of holding small end.
Described a kind of waste Crumb rubber crushing device mill, the groove depth of described movable grinding disc surface thread is 3 ~ 0mm by large scope of holding small end.
Described a kind of waste Crumb rubber crushing device mill, the axial distance of described movable grinding disc large end radius spiral shell rib is the large end radius of movable grinding disc of 0.1 times.
Described a kind of waste Crumb rubber crushing device mill, described movable grinding disc large end radius lead is the large end radius of movable grinding disc of 0.8 ~ 0.3 times to the excursion of small end by large end.
Advantage of the present utility model and effect are:
1. the utility model device mill comprises movable grinding disc and fixed millstone, and the gap in two mill faces reduces gradually.Feed arrangement produces motive force to sizing material, is constantly pushed in abrasive disk space by sizing material, and first sizing material enters large region, gap; This district adopts wider teeth groove and dark tooth, tentatively pulverizes sizing material, reduces the size of sizing material; Then enter the region that gap is little, this district adopts narrower teeth groove and shallow tooth, further pulverizes, reach satisfied crushing effect to sizing material.
2. movable grinding disc male cone (strobilus masculinus) of the present utility model adopts tapered convergence thread, and fixed millstone inner conical surface adopts straight radial shape rake tooth.Tapered convergence thread contributes to travelling forward of sizing material, reduces energy consumption.It is large that area pulverized by radial rake tooth, contributes to the abundant pulverizing of sizing material.
3. the cone angle of the utility model movable grinding disc adjustable and design profile of tooth sizing material can be made to obtain maximum pressure, have that structure is simple, assembling and convenient disassembly, crush efficiency is high, specific energy consumption is low, input and output material is unobstructed, pulverizing is even, grinding particle size is thin, quality is high.
Accompanying drawing explanation
Fig. 1 is the front view schematic diagram of the utility model mill;
Fig. 2 is the sectional view schematic diagram of the utility model mill.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in detail.
See Fig. 1, Fig. 2, the utility model is made up of movable grinding disc and fixed millstone.1 is fixed millstone, and 2 is fixed millstone rake tooth, and 3 is movable grinding disc thread, and 4 is movable grinding disc.
Feed arrangement produces motive force to sizing material, is constantly pushed in abrasive disk space by sizing material, and first sizing material enters large region, gap from large end; This district adopts wider teeth groove and dark tooth, tentatively pulverizes sizing material, reduces the size of sizing material; Then enter the region that gap is little, this district adopts narrower teeth groove and shallow tooth, further pulverizes, reach satisfied crushing effect to sizing material.
The size of the cone angle of movable grinding disc, has considerable influence for energy consumption and rubber powder fineness.Therefore the adjustable range of cone angle is 35 ° ~ 55 °.
The cross section of mill face of the present utility model crushing tooth is triangle (addendum width is zero).The design of this crushing tooth can make sizing material reach maximum positive voltage power, and then obtains maximum useful work.
Disc surface pulverize the number of teeth number be decide according to pulverizing the degree of grinding that the granularity of sizing material, character and requirement reach.If the particle of sizing material is comparatively large, then adopt the less number of teeth and darker teeth groove; The particle of sizing material is less, then adopt the more number of teeth and more shallow teeth groove.Here adopt gradual change type spiral groove depth.The groove depth of movable grinding disc surface thread is 3 ~ 0mm by large excursion of holding small end.
Smashing fineness at least can regulate by a kind of method, and it comprises: the adjustment of abrasive disk space size; The adjustment of movable grinding disc rotating speed; The change that movable grinding disc turns to; The change (comprising the change of tooth top width, tooth depth, tooth angle) of crushing tooth profile of tooth.
In the mill pulverizer course of work, mill produces two kinds of effects to scrap rubber, and one is that the High Rotation Speed of mill produces centrifugal force to scrap rubber, and scrap rubber is moved from inside to outside along mill; One is that scrap rubber is in the mechanical crushing effect by being subject to during abrasive disk space.
The pulverization of pulverizer mainly relies on the High Rotation Speed of movable grinding disc, creates huge centrifugal force, because this active force constantly throws to the flank of tooth the sizing material in teeth groove.The sizing material of pulverizer enters disintegrating area from the center of mill, and under the pivotal mill of high speed drives, sizing material moves towards circumference from center along spiral involute.Like this, sizing material is owing to being subject to centrifugal force and force of periphery synergy, and sizing material has the trend of radial motion, has again the trend moved in a circle, and because rotating disk is to the high speed relative motion of price fixing or two mills, sizing material also just rises continually and falls between tooth top and teeth groove.In this motion process, sizing material stands the effects such as centrifugal force, twisting resistance, shearing force, pressure, and result makes sizing material be pulverized.
