Abstract:
Apparatus and method in converting municipal solid waste into geo-polymer briquettes and geo-polymer bricks comprising bag opener cum crushers, magnetic separators for ferrous and eddy current separators for non-ferrous things; squeezer for removing liquid content; inter particle collision driers for drying; pulverizer for pulverizing, and devolatizing carbonization reactor for carbonisation of combustible MSW to produce solid char with low water content. Solid char is mixed with geo- polymer binding agent/starch/tar/ to form combustible pellet/briquette. These highly combustible briquette/pellets have high calorific value. The pellet/briquette is formed by rotating combustible char at high rpm and compaction. Pellet has a water content of less than 5% by weight and fuel value of 5500 to 6500 KCAL This process produces non-combustible geo-polymer brick. The non-combustible MSW separated by a trommel is crushed by inter particle collision crusher and pan mixers mixing with geo-polymer binding agent/fly ash/quarry dust/chips or china clay and moulded.
Abstract:
A wall recessed macerator is described which comprises a macerating chamber for receiving and macerating waste products, and a hood, disposed above and providing access to the macerating chamber, and having a frontal aperture through which waste products to be macerated can be placed. A cover is provided, for closing off the frontal aperture during a macerating process, and an inlet is provided, for dispensing liquid into the hood. In this way, it is possible to wall recess a macerator –previously considered to be undesirable due to the requirement for a user to place their hands inside the macerator through a front loading aperture. By providing a hood, and an inlet for dispensing (cleaning) liquid into the hood, hygiene requirements can be maintained.

Each of the rotors 30 comprises a hub 32 and a plurality of chains 34 connected to the hub 32 and designed to sweep over part of the grinding chamber 22 during rotation of the rotor 30.
Abstract:
A method and system for coal ash reclamation from a land fill, the system comprising: a harvester; a screen for screening non-ash material from ash collected by the harvester; a dryer for drying raw ash thereby creating dried coal ash and fine particulate ash; an exhaust pipe to direct the ash to a dust collector; a crusher for crushing the dried ash; a classifier for classifying the crushed dried ash; and a storage container for storage. The method comprising: harvesting raw coal ash from a land fill; screening the raw coal ash to remove oversize materials; drying the screened ash to remove water; crushing the stream of dried ash; classifying the crushed ash into fine particulate ash and large particulate ash, the second stream being directed for further crushing; streams of fine particulate ash being cooled; and storing the fine particulate ash.
Abstract:
The invention discloses a vacuum cracking apparatus for a power battery and a cracking method thereof. The cracking device includes a cylinder and further includes a rolling device, a first sealing device, a cracking device, a second sealing device, a pyrolysis device and a third sealing device which are arranged from top to bottom. The cracking device for the power battery of the present invention is equipped with the first sealing device, the second sealing device and the third sealing device to isolate the cracking device from the pyrolysis device and be capable of realizing material transmission and gas isolation without interference with each other, so that gas stirring between an anaerobic zone and an aerobic zone is avoided; and by combing battery cracking and battery pyrolysis, with cracked gas discharged after cracking as a fuel for cracking and pyrolysis or preheating a pyrolysis device, resources are fully used.
Abstract:
A food waste disposer includes: a housing; a grinding case positioned inside the housing and configured to be separable from inside of the housing to outside of the housing and treat food waste; a rotating grinder configured to treat the food waste by rotating inside the grinding case and rotatably coupled with respect to a bottom surface of the grinding case; a grinder rotating shaft inserted in the rotating grinder and configured to rotate together with the rotating grinder; and a driver positioned below the grinding case and configured to provide rotation power of the rotating grinder, wherein the driver includes: a driving motor configured to generate power; a shaft driving gear configured to rotate by receiving power of the driving motor; and a connecting shaft configured to be rotatable within a range of a first angle with respect to the shaft driving gear, wherein one end of the connecting shaft is inserted in the grinder rotating shaft and another end of the connecting shaft is inserted in the shaft driving gear to transfer power from the shaft driving gear to the grinder rotating shaft.
Abstract:
Baffles for food waste disposers, systems employing such baffles, and methods of assembling, manufacturing, fabricating, or operating such baffles or baffle systems are disclosed herein. In one example embodiment, a baffle for implementation in connection with a food waste disposer includes a rim portion, a plurality of flaps, and a plurality of living hinges, wherein the rim portion, living hinges, and flaps constitute a single integrally-formed structure. The respective living hinges permit the respective flaps to be rotatable about respective axes that respectively are substantially tangent to respective locations along or proximate to the rim portion, so that the respective flaps can be rotated to respective closed positions. Either the living hinges or at least one additional component tend to cause the respective flaps to remain at the respective closed positions or to return to the respective closed positions when not at the respective closed positions.
