Abstract
The invention discloses an ultrasonic rubber pulverizing technology and an ultrasonic rubber pulverizing device, a dynamic millstone of the pulverizing device rotates with a high speed, waste rubber particles are driven by the dynamic millstone, the thick material is continuously taken to a cutting range of an ultrasonic cutting tool, the particles greater than a cutting gap move to the surface of a stationary millstone, and so that the particles are in an ultrasonic energy field. The stationary millstone of the pulverizing device uses the ultrasonic cutting tool, by adjusting of ultrasonic frequency and amplitude, waste rubber is impacted and cut by ultrasonic into fine power. The fineness of the rubber power can completely reach above 80 meshes, and meanwhile parts of sulfide bonds in the rubber power are broken.
Description
Affiliated technical field
Patent of the present invention relates to a kind of abrasive dust equipment that utilizes ultrasonic wave to pulverize scrap rubber, the fixed millstone of its equipment adopts ultrasonic cutter, make scrap rubber under ultrasonic energy effect, reach with conventional method and equipment and be difficult to the rubber powder fineness of pulverizing, be that rubber powder fineness 100% is all more than 80 orders, and there is the effect of disconnected sulfide linkage and activated rubber powder, this rubber powder can be manufactured by tire and rubber enterprise as raw material extensive use.
Background technology
At present, along with the development of auto industry and the increase of automobile pollution, the processing of damaged tire, scrap rubber is more and more become to the important topic of environmental protection, and to manufacturing the demand of the natural rubber raw material of tire, but increasing rapidly.Waste rubber normal temperature crushing is become to thin rubber powder, be re-used as raw material and be back to use in tire production and go, by becoming best resource, supplement and select.But rubber normal-temperature pulverizes that not only energy consumption is high, conventional plant equipment is difficult to waste Crumb rubber to be broken into fine powder, and 80 order rubber powders of output only account for 65% left and right of total output conventionally, and the sulfide linkage of rubber powder cannot be interrupted, thereby physical index is lower.
Summary of the invention
Patent of the present invention is introduced ultrasonic technology, the fixed millstone of abrasive dust equipment adopts ultrasonic cutter, ultrasonic wave is not only levigate scrap rubber, also interrupted in a large number the sulphide bond of rubber powder simultaneously, make rubber powder there is higher activity, played the effect of crumb rubber activation, the rubber powder of producing than conventional method has better application performance.
This patent solves the technical scheme that its technical problem adopts: the movable grinding disc High Rotation Speed of abrasive dust equipment, waste rubber grain is promoted by movable grinding disc, constantly thick material is taken to the smear metal scope of ultrasonic wave cutlery, be greater than the movement of particles of shear gap to fixed millstone surface, make scrap rubber in hyperacoustic energy field, levigate material is taken out of to operation area simultaneously.The fixed millstone of abrasive dust equipment adopts ultrasonic cutter, the transmission speed of ultrasonic energy is 8000 meter per seconds, and the speed that the cutlery of ultrasonic wave mill is cut is also 8000 meter per seconds, by adjusting hyperacoustic frequency, amplitude, scrap rubber is through ultrasonic impact, cutting, until become fine powder.More than rubber powder fineness 100% all can reach 80 orders, the partial vulcanization key of rubber powder inside is interrupted simultaneously.
The beneficial effect of this patent is, scrap rubber is under ultrasonic wave extruding pulverization, shatter chain rupture a large amount of sulfide linkages, experimental data shows, the rubber powder that ultrasonic wave is pulverized, and not only fineness 100% is all more than 80 orders, and hardness is lower than the levigate rubber powder of conventional normal temperature method, high 1～the 4Mpa of rubber powder that hot strength after sulfuration is pulverized than conventional method, elongation at break improves 50～150%, therefore has better application performance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is movable grinding disc figure of the present invention.
Fig. 2 is fixed millstone figure of the present invention.
In the middle of fixed millstone, having macropore, is the charging aperture of material.The thickness of fixed millstone must be able to bear the thickness of transmitting ultrasonic resonance, is generally greater than 130mm, and the material that adopts aluminium alloy or titanium alloy easily to propagate is more suitable.
The specific embodiment
The invention provides a kind of new equipment, be different from current conventional rubber mill powder equipment, it has strengthened the function of ultrasonic wave and disconnected sulfide linkage levigate to scrap rubber, under the state that ultrasonic wave is not opened, equipment also can be worked, but the Efficiency Decreasing of pulverizing, the rubber size of pulverizing out is large, sulfide linkage does not interrupt; Open the speed of ultrasonic wave rear feeding and obviously accelerate, production capacity increases.
The four-stage motor that its equipment has relatively high power drives, and movable grinding disc rotates with respect to fixed millstone, and whole equipment is comprised of the relative position adjusting device of single screw rod speed governing feeding device, mill face and cooling device etc.
Claims (1)
1. the technology of patent of the present invention and equipment relate to the mill of scrap rubber abrasive dust equipment, it is characterized in that: on the fixed millstone of abrasive dust equipment, adopt ultrasonic cutter, ultrasonic wave is not only levigate scrap rubber, make rubber powder fineness 100% all more than 80 orders, also interrupted in a large number the sulphide bond of rubber powder simultaneously, make rubber powder have higher activity, played the effect of crumb rubber activation, the rubber powder of producing than conventional method has better application performance.
