1437391 Hopper wagons; transporting special loads KOPPERS CO Inc 3 July 1973 [13 Aug 1972] 31718/73 Heading B7L [Also in Division F4] For handling hot coke from a coke oven there is provided a transfer car 11 having a refractory lined hopper 19 with an opening in its top for entry of the hot coke, a stainless steel wire mesh curtain 89 to close the opening when the hopper has been filled, and means for conducting gases away from the hopper interior and cleaning them; the gas cleaning apparatus being carried by a traction car 13 coupled to the transfer car at 15. The coke enters the hopper through an opening in a sloping surface at the top of a hood 29, Fig. 2. The curtain 89 is drawn over the opening from a reel 43. Gases extracted from the hopper interior pass through a duct 39, duct 127 provided with water spray nozzles (129) Fig. 6, (not shown), and then through venturi or wet scrubbers (128), cyclone separator 119, duct 139, exhaust fan 121 and stack 141. The stainless steel wire mesh curtain 89, Fig. 2, is carried by chains 67 at its sides which pass around toothed end plates 61, 63 of the reel 43 at one side of the hopper opening and around sprockets 69, 71 at the other side. The chains 67 carry the curtain 89 by being fastened to bars 91 which are secured to the curtain by U bolts (95), Fig. 4, (not shown) and bars (93). Regulation of the travel of the curtain is controlled by a mechanism (105) Figs, 2 and 5, (not shown). The bottom of the hopper has hinged pivotal gates 23, 25. On the traction car 13 there is an operator's cab 143. Electrified collector rails 35 and shoes 33 form part of an electrical interlock system between the coke guide hood at the coke oven and the hot coke transfer car 11.
