Abstract: A low pressure feeder includes a rotor containing at least one pocket having a single access opening to it, the rotor rotatable about an axis and enclosed in a housing having an inlet port vertically above an outlet port. A sealing structure is disposed in a large clearance volume between the rotor and the housing, the sealing structure comprising a single shoe having an opening communicating with the inlet port, and one or more pressure compensators for biasing the shoe into engagement with the rotor. The pressure compensators are responsive to the process pressure at the feeder high pressure outlet port. A gas blast structure is provided for supplying a blast of gas to the pocket to effect discharge of material from the pocket when it is in communication with the outlet port. A vent is provided immediately before the inlet port in the direction of rotation of the roller, the access opening being dimensioned with respect to the vent and inlet port so that it can communicate with both during a portion of path of rotation thereof.

Abstract: A system and method for feeding comminuted cellulosic fibrous material such as wood chips to the top of a treatment vessel such as a continuous digester provide enhanced simplicity, operability, and maintainability by eliminating the high pressure transfer device conventionally used in the prior art. Instead of a high pressure transfer device the steamed and slurried chips are pressurized using one or more slurry pumps located at least thirty feet below the top of the treatment vessel and for pressurizing the slurry to a pressure of at least about 10 bar gauge. A return line from the top of the digester may, but need not necessarily, be operatively connected to the one or more pumps and if connected to the pumps the pressure in the return line may be reduced utilizing a pressure reduction valve and/or a flash tank. Steam from the flash tank may be used in steaming the chips. Pressure relief prevention may be provided by isolation valves in the lines leading to and from the top of the treatment vessel controlled by a controller which is responsive to the pressure sensed in the slurry line leading to the top of the treatment vessel.

Abstract: It is desirable to be able to treat medium consistency (e.g. about 8-12% by weight) paper pulp suspensions with treatment liquid (e.g. a wash liquid), and to thicken the pulp to about 30-50% consistency at the same time. A moving (e.g. rotating) channel is defined by a root wall and upstanding side walls--some or all of which are perforated--and treatment liquid is introduced by an arcuately elongated distributor with perforated side walls into the center of the pulp within the channel, filtrate flowing out through the perforated walls. A pivoted wall portion of the stationary housing of the treatment device restricts outflow of the thickened pulp cake from the device, the cake flowing between a doctor blade and the pivoted wall portion.

Abstract: A method and system are provided for continuously conveying hard particulate material of non-uniform size, like coal. A high pressure transfer device has high and low pressure feed and discharge lines extending to and from it, and a screen arrangement for allowing liquid and fines to pass from the low pressure feed line to the low pressure discharge line, while stopping large particles. An excess accumulation of fines is prevented by providing a screen assembly vertically above the high pressure transfer device. Level control in a hopper--which provides the low pressure feed line--is accomplished merely utilizing an overflow technique. The concentration of particles in the liquid in the high pressure discharge line is maintained about 50% by withdrawing a portion of the liquid (while still under pressure) from the high pressure discharge line, and returning it to the high pressure feed line. A density measuring device downstream of the liquid withdrawal automatically controls the amount of liquid withdrawal.

Abstract: An improved lifting mechanism for an apparatus for continuously feeding solid particles into a pressure vessel of the type disclosed in U.S. Pat. No. 4,125,384, the lifting mechanism comprising an elongated cylindrical housing assembly operatively disposed with its axis extending at an angle to the horizontal and to the vertical. The housing assembly includes end structures closing the upper and lower ends thereof, a water and particle inlet for pressure communication with the pressure vessel of the apparatus leading downwardly into the interior of the housing assembly adjacent the closed lower end thereof and a particle outlet for pressure communication with the container of the apparatus leading downwardly from the interior of the housing assembly adjacent the closed upper end thereof. A particle supporting plate extends longitudinally within the cylindrical housing assembly between the end portions thereof and is fixedly mounted along the sides thereof between horizontally spaced diametrically opposed portions of the housing assembly. A pair of parallel endless chains have upper operative flights which extend along opposite sides of the upper surface of the plate, lower parallel return flights and arcuate ends trained about sprockets carried by the housing assembly at the ends of the plate. A series of spaced perforated particle moving structures extend between the chains and are operable during the movement of the chains through their operative flight to move therewith over the upper surface of the plate and upwardly through the space thereover defined by the upper periphery of the housing assembly so that particles introduced into the lower portion of the space through the inlet are moved positively inwardly through the liquid free surface and then discharged through the outlet in a condition in which the liquid has been substantially drained therefrom.

Abstract: A method and apparatus for hydraulically transmitting coal, oil shale, mineral ores, etc. from the mine face to the surface of underground mines via a pipeline by injecting the mined material from near the mine face into a body of water flowing in a pipeline, such injection being accomplished by an injection device which moves the mined material into the pipeline without applying any pushing forces and relocates the mined material in a continuous fashion from a first low pressure water circulation loop into a second higher pressure water circulation loop. The second water circulation loop communicates as required with a second injection device which relocates the mined material to a third higher pressure water circulation loop for increasing the pressure in the pipeline for transmission from deep mines.
