Collecting hopper for materials with solid and liquid ingredients - has suction pipe to extract liquid from chamber below sieve which forms false bottom

摘要

The hopper (10) is divided by a sieve (24) forming a false bottom into a top chamber (26) collecting the solid ingredients and a bottom one (28) for liquid. The top chamber has a gastight cover (40) containing a filler opening sealed gastight by a plug, while a suction pipe (32) extracts the liquid from the bottom one. The false bottom may be a suspended basket in the hopper, while the plug can comprise a slide working in guides in the cover. The intake (34) of the suction pipe can be above the level of the bottom (30) of the bottom chamber. ADVANTAGE - Safely accommodates a large amount of solid waste such as solvent-impregnated cleaning rags, with simple separation of ingredients for disposal or reprocessing.
