Abstract
Abstract This invention concerns about a kind of multi-function automatic garbage furnace which consists of three main divisions; a garbage transporting and storing division, a burning division and a cleaning division of waste gas. The garbage transporting and storing division includes a lifting can, a garbage room, a screw conveyor; the burning division includes a main burning chamber for burning garbage and a rotating bottom net for placing garbage and for dropping ashes, in addition to secondary burning of the waste gas in the secondary burning chamber a leaf wheel, conveyors for; the cleaning division includes a cyclone tank, three sedimentation pools, a clean water pool, leading pipes, a spraying pipe in a spraying room for cleaning the waste gas coming out of the secondary burning chamber by repeated washing and blending before it is released in the open air.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
195 words
A multi-function automatic garbage furnace comprising: a garbage room for storing garbage which is to be loosened by claws of losseners and to carried into a main burning chamber by a screw conveyor, means for lifting garbage and dropping it into said garbage room, a main burning chamber having a rotating bottom net and a rotating leaf wheel under said bottom net for moving ashes which have fallen through said bottom net to a discharge slope and conveying means, first and second ring-shaped air supply pipes respectively set above and below said rotating bottom net in said main burning chamber, a secondary burning chamber for burning waste gas coming from said main burning chamber, a cyclone tank for separating comparatively large impure particles from the twice-burned waste gas coming from the secondary chamber through centrifugal action, blowers for sucking the waste gas out of the main burning chamber into the secondary burning chamber, and then into said cyclone tank, sedimentation pools for removing other impure particles in the waste gas, and a spraying room to spray clean water into the waste gas coming out of the sedimentation pool for further cleaning action of the gas.

Claim 3
Dependent Claim
177 words
A waste gas washing and cleaning system for a multifunction automatic garbage furnace including a garbage room for storing garbage which is be loosened by claws of looseners and to be carried into a main burning chamber by a screw conveyor, means for lifting garbage and dropping it into said garbage room, a main burning chamber and a secondary burning chamber for burning the waste gas from the main burning chamber, comprising; a cyclone tank for separating comparatively large impure particles from waste gas through centrifugal action, a plurality of sedimentation pools, a clean water pool, a lead pipe extending from said cyclone tank to the first of said sedimentation pools, a first spraying pipe in said lead pipe, a sieve set on the water surface in said first sedimentation pool, a spraying room, a second spraying pipe in said spraying room, a blower for sucking waste gas out of the main burning chamber and delivering said waste gas through said secondary burning chamber, said cyclone tank and said lead pipe to said first sedimentation pool, and
Claim 4
Dependent Claim
177 words
A waste gas washing and cleaning system for a multifunction automatic garbage furnace including a garbage room for storing garbage which is be loosened by claws of looseners and to be carried into a main burning chamber by a screw conveyor, means for lifting garbage and dropping it into said garbage room, a main burning chamber and a secondary burning chamber for burning the waste gas from the main burning chamber, comprising; a cyclone tank for separating comparatively large impure particles from waste gas through centrifugal action, a plurality of sedimentation pools, a clean water pool, a lead pipe extending from said cyclone tank to the first of said sedimentation pools, a first spraying pipe in said lead pipe, a sieve set on the water surface in said first sedimentation pool, a spraying room, a second spraying pipe in said spraying room, a blower for sucking waste gas out of the main burning chamber and delivering said waste gas through said secondary burning chamber, said cyclone tank and said lead pipe to said first sedimentation pool, and
Claim 5
Dependent Claim
57 words
an exit pipe from said spraying room whereby said waste gas mixes with water from said first spraying pipe and the mixture flows into said first sedimentation pool where said gas bubbles up through said sieve into said spraying room where said gas is sprayed by said second spraying pipe and flows out of said exit pipe.
Claim 6
Dependent Claim
57 words
an exit pipe from said spraying room whereby said waste gas mixes with water from said first spraying pipe and the mixture flows into said first sedimentation pool where said gas bubbles up through said sieve into said spraying room where said gas is sprayed by said second spraying pipe and flows out of said exit pipe.
