System for treating residues resulting from the combustion of a casket containing the body of a deceased person

Abstract

The system comprises:—a device ( 9 ) for sorting residues transported from the outlet of a cremation furnace to an urn, capable of separating the metallic elements and the bone remains;—a device ( 20 ) for grinding the portion of the residues that contain the bone remains without metallic elements, positioned downstream of the sorting device;—a container ( 18 ) for collecting the metallic elements, and an urn ( 23 ) for collecting the ground bone remains. Metal detection means ( 19 ) control the movement of a valve ( 16 ) between a closed position of a window ( 15 ) that opens toward a container ( 18 ) for collecting metallic elements, and a position where the metallic elements may drop through this window.

1 . A system for treating residues resulting from combustion of a casket containing a body of a deceased person, the residues comprising body remains and metal elements, the system comprising:
 a device for sorting residues transported from an outlet of a cremation furnace to an urn, capable of separating the metallic elements and the body remains;   a device for grinding a portion of the residues that contain the body remains and is substantially devoid of metallic elements, said grinding device being positioned downstream of the sorting device;   at least one container for collecting the metallic elements, and an urn for collecting the ground body remains,   wherein the sorting device comprises:   a valve movable between a first position, in which the valve covers a window of the sorting device opening toward a container for collecting the metallic elements, and a second position, in which said window is freed, the metallic elements then being able to drop through that window toward said container;   means for detecting the metals among the residues moved in the sorting device, the metal detection means being able to control the movement of the valve between the two positions thereof.   
     
     
         2 . The system according to  claim 1 , wherein the sorting device comprises a substantially horizontal conveyor equipped with vibration means capable of causing spreading of the residues in said conveyor. 
     
     
         3 . The system according to  claim 1 , wherein the sorting device comprises a substantially vertical column, in which at least part of the residues is made to drop. 
     
     
         4 . The system according to  claim 2 , wherein the conveyor emerges, downstream, in the upper portion of the column. 
     
     
         5 . The system according to  claim 2 , wherein the sorting device comprises separating means including a magnet, for the recovery of the ferrous metals, said separating means preferably being preferably positioned upstream of the metal detection means. 
     
     
         6 . The system according to  claim 5 , wherein said separating means including a magnet are positioned above the conveyor. 
     
     
         7 . The system according to  claim 3 , wherein the metal detection means are positioned on the column and the window is positioned on a side wall of the column. 
     
     
         8 . The system according to  claim 2 , wherein the metal detection means are positioned on the conveyor and the window is positioned on a lower wall of the conveyor or on a side wall of the column. 
     
     
         9 . The system according to  claim 1 , further comprising a system for cooling the residues upstream of the sorting device. 
     
     
         10 . The system according to  claim 9 , wherein the cooling system for the residues includes a container associated with means for extracting air in the container and with cooling means. 
     
     
         11 . The system according to  claim 1 , wherein the sorting device is situated at a height with respect to the urn, such that the sorting and/or grinding step may be done at least partially by gravity, and wherein the system comprises means for bringing the residues upstream of the sorting device arranged to move the residues upward as far as said sorting device. 
     
     
         12 . The system according to  claim 1 , wherein the grinding device comprises a first grinder designed to perform a first grinding operation of said portion of the residues, and a second grinder positioned downstream of the first grinder and designed to perform a second, more fine grinding operation of said portion of the residues.
