  • the drum issupported'for rotation on a plurality of rings 18 which provide a forcetransmitting, insulating means.
  • the rings are of a unique construction in that they comprise two T-shapcd members insulated from one another by a spacer madc of plastic or other suitable insulating and force-transmitting materiall A cross-section of a typical ring is shown in FIG. 3.
  • outer T- s haped portion is a metallic ring while the inner T -shaped portion is made up of a plurality of L- shaped pieces 22'a'nd 24 formed into an annular ring.
  • each of the brackets 26 are wclded to their respective stems of the T-shaped portions.
  • Bolts 28 firmly clampthc plastic spacer 30 between the brackets 26.
  • the outside of the cylinder is covered with an insulating material 16, which extends outwardly from the shell 12 past the inner frce'end of the stem 20 and engaging and covering the inner portion of the rings, but not beyond the outer face of the ring 20.
  • the insulation ring 2 0, so that the ring tracks in and rolls on the roller 40.
  • Thc rollers 40 driven by means of sprockets 44 mounted on common shafts with the rollers and interconnected by means of a chain 46.
  • the sprocket 47 is mounted on a shaft 48 driven by a pulley belt drive means, designated generally 49, corinected to a source of motive power 50, FIG. 1.
  • This electric motor 50 is a variable speed motor, so that the speed at which the drum l0 rotateson the driven rollers 40 can be adjuste d. Adjusting the speed of' ro tation' adjusts the travel of material through the drum and thus regulates the exposure of the material to cold gas. Alternate means could be provided within the scope of this invention for rotating the drum on the rings, such as hydraulic motors directly driving the rollers 40.
  • This chute passes through a box-like entrance header, designated generally 62, at the upstream end, designated generally 64, of the drum 10.
  • the upstream end 64 of the drum has an annular face plate 66 fixedly mounted thereto.
  • Overlapping the shell 12 is a cylindrical reinforcing shell 68 retained by an annular flange 70. Additional insulation is provided at 71.
  • the walls of the header 62 are insulated as shown at 72. Between the insulation 71 and the insulation on the outer wall of the header 62, there is a heat tape 65. This tape can be heated by electricity remotely controlled to prevent frost build-up in the space shown and thereby prevent wearing of the insulation.
  • a free swinging plate 74 forming a door which automatically opens and closes as shown by the phantom and full line positions respectively in FIG. 1, when material comes down the chute and enters the header on its way toward the drum 10.
  • An additional free swinging door is provided by the insulated plate 76 mounted in the transverse partition 78 which completely divides the box-like header into two compartments.
  • a stack 80 is provided communicating through the top of the header 62 with the upstream compartment 82.
  • a discharge fan 84 driven by any suitable motive means 85. The purpose of this discharge fan is to draw off air coming in with the material down the chute and also to draw off used nitrogen gas which may escape when the door 76 is opened.
  • a control damper 87 is provided on the discharge side of the fan 84.
  • the chute 60 is replaced by an alternate forced feeding means, such as a mechanical feeder 160, which reciprocates as shown by the arrows.
  • the feeder is shown basically in a schematic form comprising a trough 162 mounted on arms 164 and driven in a reciprocating motion by means of a motor and crank arm, designated generally 166. This loosely shakes the incoming material into the rotating drum.
  • the mechanism is not described in further detail herein since such feeders are known in the art. Indeed, a vibrating feeder could also be used as an alternate feeding means. It should be noted that the stack will continue to have a fan and a control damper for the same purposes as previously de scribed.
  • the first stage in the separation process is the freezing unit, and in accordance with out invention, we provide a pre-cooling chamber and a cooling chamber within our freezing unit 10.
  • Liquid nitrogen is introduced into the freezing portion of the chamber (which is downstream when viewed in the direction of travel of the material through the chamber), through a common header and a plurality of nozzles 102.
  • the nozzles spray the nitrogen into the chamber, it immediately vaporizes to low temperature gas and comes into intimate contact with the moving scrap material.
  • the helical blade transports or advances the material down the drum.
  • the inner surface of the shell 12 is continually moving with respect to the material, so that this surface is re-exposedto the cold gas intermittently and then comes in contact with the under surfaces of the material.
  • the header 100 is supported on a cable 104, which is fixedly connected at one end to and within the header 62 and is fixedly connected at the other end to any convenient structure, such as at 106.

  • a plurality of rings 110 are connected to the header and disposed about the cable to support the header on the cable.
  • the liquid nitrogen as it enters the chamber, is at a temperature of approximately -320F.
  • a flow is provided by withdrawing some of the nitrogen gas from the upstream end of the drum and pumping it back through a conduit 112 and a nozzle 114 into the downstream end of the drum 10.
  • the nitrogen gas is heavier than air and for the most part lays in the bottom of the drum, which is mounted horizontally.
  • the internal transport means tend to make the gas flow out the discharge end.
  • the reverse flow condition tends to inhibit this loss. It is difficult to maintain a closed fluid flow system with so many openings at the entrance and discharge and, therefore, it is necessary to pump gas in at the discharge end to maintain the flow.
  • the compartment 84 essentially communicates only through the port 86in the end plate 66 within the cavity 89 formed within the shell 12. Used nitrogen gas is drawn out through this port 86 and down through the conduit 88 by means of the recirculating fan 90 which runs constantly as the device is operating. 1n the processing of scrap iron, for example, this recirculation of gas is at a temperature of about l50F once the unit reaches its continuous operating condition.
  • the nozzle 114 is replaced by an ejector 214 mounted on the discharge end of the conduit 112.
  • the intake end of the injector is provided with a control damper 216.
  • the discharge header 218 embraces the discharge end of the rotating drum 10 to form a chamber for mounting the ejector 214, as clearly illustrated in the figures.
  • the bottom of the header 218 has a plurality of trap doors 220 which are rotatably mounted to swing between the closed position shown in full lines and the open position shown in phantom line'srThe doors are spring biased or counter weight ed by ansuitable means (not shown) to return to their closed position when not acted upon by material being discharged from the drum 10.
  • Protective means in the form'of angle irons and the like are provided mounted above the hinges to prevent jamming of the hinge by material exiting from the unit.
  • the doors open into achute 222, which has a second pair of similarly mounted doors 224, which function in a similar fashion as shown by the solid and phantom lines.
  • the chute 222 opens into the crusher 92.
  • the ejector improves the operation of the-system by recirculating a portion of the nitrogen WhlCh WOUld otherwise be discharged. This portion of the nitogen is drawn into the ejector from the discharge header 218 as shown by the arrows in FIG. 6'and isinduced to flow from the discharge end of the drum toward the intake or upstream end of the drum.
  • the flow pattern provided by the recirculating system provides a pre-cooling chamber in the upstream portion of the drum 10 between the port 86 and that nozzle which is positioned at the upstream end of the header 100.
  • this pro-cooling chamber the nitrogen gas which has lost muchof its cooling power by virtue of contact with the material inthe drum in the downstream freezing portion thereof, is exposed to the incoming material to reduce its temperature before it enters the freezing chamber, thereby increasing the effectiveness of the system in the freezing portion of the drum.
  • thermocouples are provided as at 300, 301, 302, 303, 304 and 305 to monitor temperature and for use in adjusting the controls.
