Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
200 words
An automotive unit for the collection and incineration of refuse, for instance household or industrial refuse, comprising a substantially fluid-tight incineration assembly in turn comprising a double walled rotary furnace substantially in the shape of a truncated cone and having one end forming a refuse charging hole and an other end forming an ash and incineration residue discharge hole, burners arranged in the furnace for the incineration of the refuse, an outer casing extending in coaxial relationship to the said furnace and turning jointly with the latter, said outer casing being closed at both its ends and extending beyond the furnace refuse charging hole so as to form an ash storage receptacle, means for charging refuse into the furnace and comprising a substantially fluid-tight device including an endless screw, a charging conduit substantially in the shape of a truncated cone between said endless screw and the charging end of the furnace for leading refuse advanced by said screw into the charging end of the furnace, a fume discharge sheath connected in a substantially fluid-tight manner to one end of the furnace, and means in operative communication with said sheath for the after-burning and cleaning of the fumes and combustion gases.
Claim 2
Dependent Claim
200 words
An automotive unit for the collection and incineration of refuse, for instance household or industrial refuse, comprising a substantially fluid-tight incineration assembly in turn comprising a double walled rotary furnace substantially in the shape of a truncated cone and having one end forming a refuse charging hole and an other end forming an ash and incineration residue discharge hole, burners arranged in the furnace for the incineration of the refuse, an outer casing extending in coaxial relationship to the said furnace and turning jointly with the latter, said outer casing being closed at both its ends and extending beyond the furnace refuse charging hole so as to form an ash storage receptacle, means for charging refuse into the furnace and comprising a substantially fluid-tight device including an endless screw, a charging conduit substantially in the shape of a truncated cone between said endless screw and the charging end of the furnace for leading refuse advanced by said screw into the charging end of the furnace, a fume discharge sheath connected in a substantially fluid-tight manner to one end of the furnace, and means in operative communication with said sheath for the after-burning and cleaning of the fumes and combustion gases.
Claim 3
Dependent Claim
28 words
A unit according to claim 1, wherein the charging end of the furnace is closed by a pot connected with said charging conduit and said fume discharge Sheath.
Claim 4
Dependent Claim
75 words
A unit according to claim 1, wherein a helical blade or screw is provided on the internal face of the said casing over at least a portion of its length, between the latter and the outer wall of the furnace, for driving and guiding the ashes and incineration residues from the point of discharge into said ash receptacle to the opposite end of the ash receptacle under rotative action of the furnace and the casing.
Claim 5
Dependent Claim
24 words
A unit according to claim 3, wherein said casing includes at least one door for discharging the ashes and residues outside the ash receptacle.
Claim 6
Dependent Claim
27 words
A unit according to claim 1, wherein the said rotary furnace is of thin sheet-metal, its inner wall being provided with pulsed-air blowing perforations for tridirectional blowing.
Claim 7
Dependent Claim
58 words
A unit according to claim 5, wherein the inner wall of the furnace comprises alternating substantially plane plates and omega-section plates whose concavity faces the outside of the furnace, the said plane plates being mounted in alternating and free axial and tangential sliding mutual relationship so as to allow expansion of the said inner wall of the furnace.
Claim 8
Dependent Claim
52 words
A unit according to claim 5, wherein the air blown through the orifices of the inner wall of the furnace is conveyed by a stationary angular sheath with a rotary joint, which is arranged between two annular cheeks secured to the rotary furnace and which is connected to a blown-air intake nozzle.
Claim 9
Dependent Claim
58 words
A unit according to claim 7, wherein said annular sheath is formed of a sheetsteel band wound on and between sliding and guiding binders secured to the said cheeks and being of a material having a low coefficient of friction, a tightening device being provided and including an adjustable tension spring for tightening said band on said binders.
Claim 10
Dependent Claim
38 words
A unit according to claim 1, wherein the said fume afterburning means comprise a burner placed at the outlet of the said volute member and the flame of which covers substantially the whole cross-section of the said sheath.
Claim 11
Dependent Claim
88 words
A unit according to claim 1 wherein the fume and combustion gas cleaning means comprise a cyclone whose sucking turbine is mounted in a flue for discharge to atmosphere, the lower portion of which penetrates in an adjustable waterlevel tank, a fume admission volute member surrounding the said flue and opening into said tank in predetermined relation to said water level, and a cold water spraying distributor mounted at the inlet of said volute member and a distributor producing water streaming on the wall of said volute member.
Claim 12
Dependent Claim
33 words
A unit according to claim 2, wherein the said pot comprises an inspection hole which can be closed by a shutter whose opening is adjustable in accordance with the temperature of the fumes.
Claim 13
Dependent Claim
29 words
A unit according to claim 2, wherein the said furnace is equipped with two burners, at least one of which is controlled by the temperature of the said furnace.
Claim 14
Dependent Claim
32 words
A unit according to claim 1, comprising a Diesel engine rotating at a constant speed to drive the hydraulic pump for the supply of hydraulic motors for operating the entire incineration plant.
Claim 15
Dependent Claim
62 words
A unit according to claim 1, having a rear portion including said device for charging refuse into the furnace and said means for the after-burning and cleaning of the fumes, said rear portion being movably mounted on the frame of the unit by means of disconnectable hinges and locking devices and including rack props enabling it to be supported when being dismounted.
