Abstract
A refuse storage equipment for temporary storage and timely discharge of refuse which includes a storage tank having a refuse charging hopper at its top and a refuse discharge port at its bottom and a plurality of dampers adapted to divide the space within the storage tank into a plurality of storage compartments, the dampers being sequentially actuated beginning with the uppermost one to allow the refuse to fall from the uppermost to the lowermost of each storage compartment and discharged from the refuse discharge port in sequence.
Claims8
A medical refuse storage apparatus for temporary storage and timely discharge of medical refuse intermingled general refuse and industrial waste comprising:
- a storage tank having a refuse charging hopper at its top and a refuse discharge port at its bottom;
- an upper damper movable in a horizontal direction for partitioning an interior space within said storage tank into two storage compartments, an upper storage compartment and a lower storage compartment, when closed;
- a lower damper disposed vertically swingable in a bottom of said interior space for individually opening and closing said refuse discharge port;
- upper damper actuating means for actuating said upper damper between an open position and a closed position;
- lower damper actuating means for actuating said lower damper between an open position and a closed position;
- a pressure gauge, for measuring a reaction of said upper damper against the refuse during said upper damper closing, being disposed in the upper damper actuating means;
- a conveyance system disposed under said refuse discharge port of said storage tank for transporting the refuse discharged from said refuse discharge port away from said storage tank;
- control means for adjusting the conveying speed of said conveyance system and the opening and closing timing of said dampers;
- and
- wherein the upper and lower dampers are sequentially opened and closed to fall the refuse once into said lower storage compartment from the upper storage compartment, then the refuse is discharged from said refuse discharge port, while the refuse is continuously conveyed into an incinerator by adjusting the conveying speed of said conveyance system and opening and closing timing of said dampers by said control means, and the closing action of said upper damper is stopped when the measurement by said pressure gauge exceeds a preset pressure during the closing action of said upper damper so that refuse packages packed with the medical refuse may not be broken by said upper damper.

A medical refuse storage apparatus for temporary storage and timely discharge of medical refuse intermingled general refuse and industrial waste comprising:
- a storage tank having a refuse charging hopper at its top and a refuse discharge port at its bottom, with an interior space partitioned vertically into a plurality of chambers mutually differing in volume by a vertical partition;
- a plurality of upper damper movable in a horizontal direction for dividing each chamber into two storage compartments, an upper storage compartment and a lower storage compartment, when closed;
- a plurality of lower damper disposed vertically swingable in a bottom of each chamber for individually opening and closing the refuse discharge ports of each chamber;
- upper damper actuating means for selectively actuating said upper damper between an open position and a closed position;
- lower damper actuating means for selectively actuating said lower damper between an open position and a closed position;
- a pressure gauge for measuring a reaction of said upper damper against the refuse during said upper damper closes, being disposed in the upper damper actuating means;
- a conveyance system disposed under said refuse discharge port of said storage tank for transporting the refuse discharged from said refuse discharge port away from said storage tank;
- control means for adjusting the conveying speed of said conveyance system and the opening and closing timing of said dampers;
- and
- wherein the upper and lower dampers are sequentially opened and closed to fall the refuse once into said lower storage compartment, then the refuse is discharged from said refuse discharge port, while the refuse is continuously conveyed into an incinerator by adjusting the conveying speed of said conveyance system and opening and closing timing of said dampers by said control means, and the closing action for said upper damper is stopped when the measurement by said pressure gauge exceeds a preset pressure during the closing action of said upper damper so that refuse packages packed with the medical refuse may not be broken by said upper damper;
