Abstract
Abstract In order to discharge granular material from a container a discharge pipe including a trap is provided in the lower part of the container. Granular material flows upwardly in the trap to an equilibrium level. Injected fluid flushes granular material from the trap out of the container. More granular material flows into the trap to replace that which has been flushed out.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
209 words
Apparatus for discharging particulate material from a container holding said material, comprising: support means in the container for maintaining the particulate material in said container against the influence of gravity, discharge means formed in said support means and extending spatially from said support means from the side thereof opposite that portion of the interior of the container within which said particulate matter is held, trap means spaced from the support means and open at the end thereof disposed nearest to said support means, the open end thereof communicating with an extended portion of said discharge means, the discharge means thereby communicating the aforesaid interior portion of said container in which the particulate matter is held with the interior of said trap means; with the extended portion of said discharge means being received within the open end of said trap means, means for injecting fluid into the trap means to force particulate material through the open end thereof, which particulate material has emptied into said trap means from the container through said discharge means, and base means mounting said trap means in spaced relation to said support means and discharge means, said base means having at least one aperture therein through which material forced from said trap means may pass.
Claim 2
Dependent Claim
209 words
Apparatus for discharging particulate material from a container holding said material, comprising: support means in the container for maintaining the particulate material in said container against the influence of gravity, discharge means formed in said support means and extending spatially from said support means from the side thereof opposite that portion of the interior of the container within which said particulate matter is held, trap means spaced from the support means and open at the end thereof disposed nearest to said support means, the open end thereof communicating with an extended portion of said discharge means, the discharge means thereby communicating the aforesaid interior portion of said container in which the particulate matter is held with the interior of said trap means; with the extended portion of said discharge means being received within the open end of said trap means, means for injecting fluid into the trap means to force particulate material through the open end thereof, which particulate material has emptied into said trap means from the container through said discharge means, and base means mounting said trap means in spaced relation to said support means and discharge means, said base means having at least one aperture therein through which material forced from said trap means may pass.
Claim 3
Dependent Claim
76 words
The apparatus of claim 1 wherein said means for injecting fluid into the trap means comprises: a nozzle assembly mounted within said trap means and spaced from said discharge means extending into said trap means, said nozzle assembly including a plurality of radially outwardly facing nozzles, pipe means for supplying fluid to said nozzles, and a protective cap disposed over said nozzles for preventing contact between said nozzles and the particulate matter in said trap means.
Claim 4
Dependent Claim
57 words
The apparatus of claim 2 wherein said discharge means comprise a plurality of substantially cylindrical pipes and said trap means comprise a plurality of substantially cylindrical receptacles open at one eNd thereof, said pipes being open at both ends thereof and each extending from said support means into the open end of one each of said receptacles.
Claim 5
Dependent Claim
52 words
The apparatus of claim 3 and further comprising: base means mounting said trap means in spaced relation to said support means and discharge means, said latter base means having a plurality of apertures therein disposed between said trap means and providing exits through which material forced from said trap means may pass.
