Apparatus for the pyrolysis of waste products

Claim 1

An apparatus for carrying out the pyrolysis of waste products comprising: a reactor vessel having an entrance end and a delivery end; heating means disposed around said reactor vessel for heating the waste products in the vessel; an air tight charging hopper at the entrance end of the reactor vessel; an air tight delivery chamber at the delivery end of said reactor vessel; means for driving the waste products through the reactor vessel between said entrance and delivery ends said driving means including a hollow shaft member for conducting hot fluid through said delivery means, said hollow shaft member including a plurality of through apertures, said shaft member further including a plurality of transverse tube members for preventing the escape of the hot fluid said tube members being gas tightly disposed within the through apertures of the shaft member, said driving means further including a plurality of arcuate blade members having elongated stem portions, said stem portions being slidingly fitted within said transverse tube members whereby the heat created by the hot fluid conducted through the hollow shaft is quickly transmitted through the transverse tube members, to the stem portions of the blade members, to the blades and to the waste products being treated; a blower, the suction side of which is connected to the delivery end of the vessel; and means for adjusting the angle of inclination of the reactor vessel relative to the horizontal whereby the reaction time of the waste products in the vessel can be controlled.
