  • Patent number: 4545717
    Abstract: A charging machine for charging a glass melting tank furnace includes a reciprocatable charging table above which a hopper is provided for the batch, at the rear side of which at least one movable scraper is provided which seals the slot between the rear wall of the batch hopper and the top surface of the loading table. In order to eliminate the wear on the lower edge of the movable scraper and the surface of the charging table which comes into engagement with the movable scraper, the movable scraper is connected to stroke elements for lifting and lowering, whose stroke is controlled in dependency on the movements of the loading table in such a manner that the movable scraper is lifted during the forward movement of the charging table and is lowered during the return movement of the charging table. In this charging machine, wear occurs only during the table return movement, but not during the table forward movement, so that the wear is cut in half, thus doubling the service life of the machine.

  • Patent number: 4537140
    Abstract: An improvement for use in a coal stoker is disclosed. The improvement device is used with a common stoker generally including a hopper operatively connected to and aligned with a base box forming an ash pit. The base box, through its sides sloping downward from the hopper, supports a ramp. The lower part of the ramp is a perforated fire grate while the upper section is a plate that extends through the hopper bottom. A fan effecting a forced draft through the grate is operatively connected to a motor. The improvement comprises a linear reciprocation action carpet that overlies generally the length and width of the plate. The carpet's movement is effected by its connection to the motor. When coal is fed into the hopper and the movable carpet is activated by the motor, the carpet will move in a linear reciprocating direction. The coal falling on the carpet from the hopper will continually advance in an even flow from the carpet's leading edge onto the perforated grate.

  • Patent number: 4315712
    Abstract: A loading method and loading device for feeding waste-filled containers into a rotary incinerator, wherein open topped containers are filled with liquid, pasty, or solid waste materials and are fed sequentially using a reciprocating ram via a slide onto a loading and dumping platform. This loading and dumping platform projects from the stationary incinerator inside wall into the drum of the rotary incinerator. Each container placed on the loading and dumping platform is allowed to stand for one loading time interval during which a portion of the combustible volatile components of the waste contents is gasified and burned by the heat radiating from the fire in the drum. After this initial combustion, the reciprocating ram feeds the next container in sequence onto the loading and dumping platform and, at the same time, tips the first container off the platform into the drum. The combustible waste residue of this tipped container spreads out on the lower wall of the drum and burns, releasing further heat.

  • Patent number: 4249855
    Abstract: A method for introducing particulate solids upwardly through a bottom solids inlet of a solids upflow vessel wherein after full extension of a piston to displace solids from a feed cylinder into the solids upflow vessel, the piston is partially retracted to "relax" the bed of solids in the solids upflow vessel. The bed relaxation step reduces the piston-to-solids pressure during the pumping stroke as well as substantially reducing the solids loading pressure on the device used to prevent backflow of solids from the upflow vessel during refilling of the feed cylinder.
