Abstract
An apparatus for discharging flowable material, particularly a powder or other particulate material, is provided with a hopper, bin, silo or the like having a discharge outlet with a closure, also known as an .alpha.-flange, and spaced therefrom a device, such as a cone, for obturating flow of material from the outlet, and a mechanism which is connectible with the obturating device and is operative to open the closure and obturating device in sequence. The mechanism also closes the obturating device and closure in reverse sequence.
Claims22
An apparatus for discharging flowable material, comprising:
- a hopper for the material having a discharge outlet with a closure arranged to sealingly cooperate with a closure of a receptacle and, spaced from the outlet within the hopper, a device for obturating flow of material towards the outlet;
- and
- a mechanism, within the hopper, which is connectible with the obturating device and is operative to open the discharge outlet closure and the obturating device in sequence.
An apparatus including a hopper for flowable material, comprising:
- isolation means associated with an outlet of the hopper for isolating the outlet from the exterior, the isolation means comprising an annular ring, and means to extract material from within the isolation means,
- wherein the annular ring comprises an angle ring, a flexible skirt, and means, including a plurality of piston and cylinder arrangements, to maintain the annular ring in position against the hopper outlet.
An apparatus including a hopper for flowable material, comprising:
- isolation means associated with an outlet of the hopper for isolating the outlet from the exterior, the isolation means comprising an annular ring, and means to extract material from within the isolation means,
- wherein the annular ring comprises an angle ring, a flexible skirt, means to maintain the annular ring in position against the hopper outlet, and means to direct washing fluid towards the hopper outlet.
An apparatus including a hopper for flowable material, comprising:
- isolation means associated with an outlet of the hopper for isolating the outlet from the exterior, the isolation means comprising an annular ring, and means to extract material from within the isolation means,
- wherein the annular ring comprises an angle ring, a flexible skirt, means to maintain the annular ring in position against the hopper outlet, and vacuum means for cleaning the hopper outlet.
