    Abstract: The invention relates to a method of, and an arrangement for, filling a large-capacity silo with a fluidizable material while preventing air-flow or gas-flow separation, in the case of which the material-charging operation takes place in a controlled manner via a delivery line, feed channel and air- or gas-delivery channels into the top part of the large-capacity silo, towards the silo wall, and downwards to the surface of the material above the base of the large-capacity silo. The material-charging operation is combined with a uniform and controlled suction-extraction operation for air or gas, which is carried out by means of one or more essentially annular suction-extraction lines, arranged directly beneath the silo top, or via annular suction gaps on the material-outflow heads.

  • Publication number: 20130209181
    Abstract: A self-emptying vacuum apparatus for use by gold prospectors includes a collection chamber, a vacuum source, a suction hose connected to the collection chamber for vacuum-collecting material from a work surface, and a flapper assembly for discharging accumulated material. During operation, the vacuum source creates a vacuum within the collection chamber sufficient to close a flapper of the flapper assembly, thereby creating a vacuum seal that causes the flow of air through the suction hose, into the collection chamber, and out of the vacuum source, allowing vacuum-collected material to drop into the collection chamber. When the weight of material accumulated within the collection chamber is sufficient to overcome the vacuum force maintaining the flapper closed, the flapper opens to discharge the accumulated material. As soon as each accumulated load of vacuum-collected material is discharged, the flapper is again drawn closed, and the collection and discharge cycle is repeated.

    Abstract: The invention relates to a method of, and an arrangement for, filling a large-capacity silo with a fluidizable material while preventing air-flow or gas-flow separation, in the case of which the material-charging operation takes place in a controlled manner via a delivery line, feed channel and air- or gas-delivery channels into the top part of the large-capacity silo, towards the silo wall, and downwards to the surface of the material above the base of the large-capacity silo. The material-charging operation is combined with a uniform and controlled suction-extraction operation for air or gas, which is carried out by means of one or more essentially annular suction-extraction lines, arranged directly beneath the silo top, or via annular suction gaps on the material-outflow heads.

  • Patent number: 6659284
    Abstract: A process, a means of transferring mineable material from any number of sources to a number of devices capable of separating out values from that mineable material. See (FIG. 1) the mineable material enters the hose (1), the hose (1) being under vacuum, and is transferred in a flow of air to the upper portion of a hopper (2). The hopper (2) is also under vacuum. The flow of air leaves the upper portion of the hopper (2) through hose (4), which is connected, to a vacuum blower (5). The mineable material, being heavier than air is deposited in the hopper (2). The mineable material is removed from the bottom of the hopper (2) by means of a variable speed drive screw conveyor (3) and is transferred to a separation device (8). The level of heavy mineable material (6) contained in the hopper (2), along with the mineable material contained in the screw conveyor (3) causes a seal against the force of vacuum and allows the mineable material to enter and be removed from hopper (2) simultaneously if desired.

  • Patent number: 6634833
    Abstract: A pneumatic conveying apparatus, having a conveyor line path installed with a first valve and a second valve. An article is conveyed through the conveyor line path. The first and second valves are both open to a vacuum source to provide a sucking force to the article, so as to initiate conveying the article. After a flow of the article through the whole conveyor line path is established, the second valve is closed to form an air cushion at the terminal end of the conveyor line path. The terminal velocity of the article is thus reduced without causing any damage or breakage.

  • Patent number: 6231273
    Abstract: A separator is disposed between a grinder and a boiler so as to select, on the basis of size, particles produced by grinding a fuel in the grinder and conveyed by a flow of air from the grinder to the separator, and then to the boiler. The separator extends in an axial direction and includes output compartments, each of which underlies a respective conveyor duct connecting the separator to the boiler. An isolating valve member is mounted to move inside the separator, and is moved in translation in the axial direction either to allow the flow to pass through all of the output compartments into the conveyor ducts or else to prevent said flow from passing therethrough. This isolating valve member makes it possible to close all of the output compartments together. In this way, it is possible to reduce the number of isolating valve members to the number of separators in a grinding installation, regardless of the number of conveyor ducts from each separator.
