Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
A sintering and dust collecting system including a multicell centrifugal dust separator having a housing one longitudinal side of which is open to constitute a gas inlet, a gas outlet connected to said housing, a sintering and burning machine for ores or the like having a permeable movable grate, suction boxes positioned below said gas permeable grate arranged adjacent one another in series along the length of the machine, gas removal conduits connected to said suction boxes, each conduit being provided with a throttling Valve, bunkers with catch screens connected to said conduits one adjacent each said valve, said gas removal conduits from the suction boxes being arranged adjacent one another and connected directly to the gas inlet of said multicell centrifugal force dust separator along its entire length the gas inlet being substantially equal in length to the combined length of the suction boxes along the length of the sintering machine.
Claim 2
Dependent Claim
152 words
A sintering and dust collecting system including a multicell centrifugal dust separator having a housing one longitudinal side of which is open to constitute a gas inlet, a gas outlet connected to said housing, a sintering and burning machine for ores or the like having a permeable movable grate, suction boxes positioned below said gas permeable grate arranged adjacent one another in series along the length of the machine, gas removal conduits connected to said suction boxes, each conduit being provided with a throttling Valve, bunkers with catch screens connected to said conduits one adjacent each said valve, said gas removal conduits from the suction boxes being arranged adjacent one another and connected directly to the gas inlet of said multicell centrifugal force dust separator along its entire length the gas inlet being substantially equal in length to the combined length of the suction boxes along the length of the sintering machine.
Claim 3
Dependent Claim
32 words
The system of claim 1 in which two said multicell centrifugal force dust separators are provided each said dust separator being operatively connected to each said suction box by a said conduit.
Claim 4
Dependent Claim
58 words
The system of claim 1 in which two said multicell centrifugal force dust separators are provided, a first of dust separators being operatively connected to a first series of said suction boxes of said sintering machine, and the second of said dust separators being operatively connected to a second series of said suction boxes of said sintering machine.
