Abstract
Abstract An apparatus for the production of ceramically bound bodies of bulking clay which comprises a housing defining a passage-through chamber, adapted to blow alternately highly heated gas in opposite directions through a heap of debris of a granulate capable of swelling in a form box received in the chamber up to swelling and ceramic binding of the surfaces of the granulate. A gas feeding device and a heat storage are provided. The passagethrough chamber includes the heat storage in the direction of the flow of the gas driven alternately back and forth on both sides of the form box. A burner feeding device for a gaseous mixture is arranged which operates controlled and regulated. Chamber sections are disposed between the heating storage and the form box. The chamber sections constitute burner chambers, and a flue gas branch is disposed within the range of the gas feeding device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
An apparatus for the production of ceramically bound bodies of bulking clay comprising a housing defining a passage-through chamber, adapted to blow alternately highly heated gas in opposite directions through a heap of debris of a granulate capable of swelling in a form box received in said chamber up to swelling and ceramic binding of the surfaces of said granulate, a gas feeding device, a heat storage, said passage-through chamber including said heat storage in the direction of the flow of said gas driven alternately back and forth on both sides of said form box, a burner feeding device for a gaseous mixture and opErating controlled and regulated, chamber sections disposed between said heating storage and said form box, said chamber sections constituting burner chambers, and a flue gas branch disposed within the range of said gas feeding device.
Claim 2
Independent Claim
139 words
An apparatus for the production of ceramically bound bodies of bulking clay comprising a housing defining a passage-through chamber, adapted to blow alternately highly heated gas in opposite directions through a heap of debris of a granulate capable of swelling in a form box received in said chamber up to swelling and ceramic binding of the surfaces of said granulate, a gas feeding device, a heat storage, said passage-through chamber including said heat storage in the direction of the flow of said gas driven alternately back and forth on both sides of said form box, a burner feeding device for a gaseous mixture and opErating controlled and regulated, chamber sections disposed between said heating storage and said form box, said chamber sections constituting burner chambers, and a flue gas branch disposed within the range of said gas feeding device.
Claim 3
Dependent Claim
48 words
The apparatus, as set forth in claim 1, wherein said gas feeding device has a controlingly driven double piston in the gas flow path, which moves back and forth the substantially closed gas volume between said pistons through said form box, said burner chamber and said heat storage.
Claim 4
Dependent Claim
30 words
The apparatus, as set forth in claim 2, wherein said double piston is disposed in a conduit, and said conduit follows on the down stream side of said heat storage.
Claim 5
Dependent Claim
43 words
The apparatus, as set forth in claim 1, wherein said gas feeding device comprises two mechanically separated yet drivingly connected individual pistons, one of said pistons being disposed on the downstream flow path behind each of said heat storages in said passage-through chamber.
Claim 6
Dependent Claim
34 words
The apparatus, as set forth in claim 1, wherein said gas feeding device comprises a reversing controllable blower and disposed in a conduit, and said conduit connects the downstream side of said heat storages.
Claim 7
Dependent Claim
25 words
The apparatus, as set forth in claim 5, which includes at least one gas cooler disposed between said gas feeding device and said heat storage.
Claim 8
Dependent Claim
47 words
The apparatus, as set forth in claim 1, wherein said burner feeding device includes conduits, said gas feeding device includes at least one pressure producing piston, and said conduits feeding combustion air selectively at least partially into the flowing path in front of said pressure producing piston.
Claim 9
Dependent Claim
59 words
The apparatus, as set forth in claim 5, wherein said burner feeding device includes a conduit for combustion air terminating at the suction side of said blower between said flue branch and said blower, and adapted to feed said combustion air required for the mixture formation selectively controlled at least partly into said gas outside of said burner chambers.
