Description
Technical field
The present invention relates to rubber pulverizing equipment technical field, particularly relate to a kind of cooled with liquid nitrogen rubber pulverizing system.
Background technology
The junked tire that a large amount of heap is abandoned, by traditional burning mode process, not only causes severe contamination to environment, and owing to also containing rubber, metal steel wire and the fiber that can reclaim processing and utilization again in junked tire, burning disposal mode certainly will cause the wasting of resources.In order to recycle the rubber constituent in junked tire, the employing also had decomposites recycling oil product or carbon black by catalyst in cracking reaction mode from waste tire rubber, but which still can produce a large amount of waste gas to environment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple, repeatedly can pulverize the cooled with liquid nitrogen rubber pulverizing system of grinding to rubber.
In order to realize above object, the technical solution used in the present invention is:
A kind of cooled with liquid nitrogen rubber pulverizing system, comprise the freezing funnel, screw feeder, grinder, cyclone separator, air blast and the liquid nitrogen bucket that are connected by pipeline, wherein said freezing funnel has charging aperture, discharging opening, returning charge mouth and liquid nitrogen mouth, described grinder has charging aperture, discharging opening and liquid nitrogen mouth, material is successively along the sequential loop of freezing funnel, screw feeder, grinder, cyclone separator, air blast and freezing funnel, and the delivery outlet of liquid nitrogen bucket connects the liquid nitrogen mouth of freezing funnel and grinder to provide liquid nitrogen both this by pipeline.
Rubber carries out preliminary combination cooling with liquid nitrogen freezing in funnel, send in grinder by screw feeder subsequently, liquid nitrogen bucket also can enter in grinder by the liquid nitrogen mouth of grinder simultaneously, rubber and liquid nitrogen carry out secondary combination cooling, with after through grinder grind into powder, rubber powder drives first removing foreign matter in cyclone separator through air blast, rubber powder returns in freezing funnel through the returning charge mouth of freezing funnel again subsequently, circulate next time, can obtain after repeatedly circulation particle diameter thinner evenly rubber powder.
Further, working chamber is formed in described grinder, described working chamber and charging aperture, discharging opening is communicated with liquid nitrogen mouth, also be provided with in this working chamber and grind rotary body, guide vane and the open adjuster of slit, described grind rotary body periphery and working chamber inwall near thus working chamber is divided into both sides, wherein charging aperture and discharging opening lay respectively at working chamber both sides, described guide vane and the open adjuster of slit and discharging opening homonymy, the slit passed through for material is left between guide vane and the open adjuster of slit, this slit size is controlled by the open adjuster of slit.
The liquid nitrogen combination cooling that rubber inputs in grinder and from liquid nitrogen bucket, cooled rubber is easier to be grated rotary body pulverizing and is ground to rubber powder, slit wherein between guide vane and the open adjuster of slit only allows to be less than the rubber powder of this slit or rubbery chip passes through, and the size of the rubbery chip that grinder exports or rubber powder has certain screening effect.
Further, the working chamber inwall of described grinder is provided with a circle and grinds the peripheral close liner 34 of rotary body.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Fig. 2 is the structural representation of grinder of the present invention.
Wherein, the freezing funnel of 1-, 2-screw feeder, 3-grinder, 31-grinds rotary body, 32-guide vane, the open adjuster of 33-slit, 34-liner, 4-cyclone separator, 5-air blast, 6-liquid nitrogen bucket, 71-charging aperture, 72-discharging opening, 73-returning charge mouth, 8-liquid nitrogen mouth.
