Abstract
An infectious waste feed system for comminuting infectious waste and feeding the comminuted waste to a combustor automatically without the need for human intervention. The system includes a receptacle for accepting waste materials. Preferably, the receptacle includes a first and second compartment and a means for sealing the first and second compartments from the atmosphere. A shredder is disposed to comminute waste materials accepted in the receptacle to a predetermined size. A trough is disposed to receive the comminuted waste materials from the shredder. A feeding means is disposed within the trough and is movable in a first and second direction for feeding the comminuted waste materials to a combustor.
Claims20
An infectious waste feed system for a combustor, the feed system comprising:
- a receptacle for accepting waste materials;
- means for comminuting the waste materials to a predetermined size, said comminuting means disposed to comminute waste materials accepted in the receptacle;
- a trough disposed to receive the comminuted waste materials;
- feeding means disposed within the trough, said feeding means being movable in a first and a second direction within the trough for feeding the comminuted waste materials to the combustor;
- and
- means for maintaining a negative pressure throughout the feed system to prevent the inadvertent egress of contaminated air.
An infectious waste feed system for a combustor, the feed system comprising:
- a receptacle for accepting waste materials;
- means for comminuting the waste materials to a predetermined size, said comminuting means disposed to comminute waste materials accepted in the receptacle;
- a trough disposed to receive the comminuted waste materials;
- feeding means disposed within the trough, said feeding means being movable in a first and a second direction within the trough for feeding the comminuted waste materials to the combustor;
- and
- a hopper disposed intermediate the comminuting means and the trough for receiving the waste materials comminuted by the comminuting means, the hopper including inclined sides to facilitate the passage of comminuted waste materials to the trough, and compressed air jets disposed in the inclined sides to prevent blockage of the hopper.
An infectious waste feed system for a combustor, the feed system comprising:
- a receptacle for accepting waste materials;
- means for comminuting the waste materials to a predetermined size, said comminuting means disposed to comminute waste materials accepted in the receptacle;
- a trough disposed to receive the comminuted waste materials, the trough having a first end and a second end;
- and
- feeding means disposed within the trough, said feeding means being movable in a first and a second direction within the trough for feeding the comminuted waste materials to the combustor;
- and
- a feed duct including a first and a second end, the first end of the feed duct positioned adjacent the second end of the trough, the first end of the feed duct including a nonmovable shear edge projecting into the feed duct to cut off any projecting waste material as the material enters the feed duct.
