Apparatus for pressing and dehydrating of waste
View Patent ↗Apparatus for pressing and drying a pre-defined amount of waste includes a metal main frame positioned to provide rigid support, and a body mechanically linked to the main frame through a plurality of linkage plates. The apparatus also includes an inlet vertically mounted on the body and a twin screw assembly to press and dehydrate the pre-defined amount of waste. A plurality of mesh screens is rigidly linked to the main frame along the longitudinal axis of the apparatus to remove compressed liquid. The body is also designed to support rotation of the twin screw assembly, and the inlet includes an ingress cross-sectional opening to receive the pre-defined amount of waste.
1. An apparatus for drying waste, comprising:
a tumbler assembly housed within a heating chamber;
the tumbler assembly dries a predefined amount of waste by conduction;
the tumbler assembly includes:
one or more hollow members that are heated from within to dry a predefined amount of waste by conduction;
the one or more hollow members include:
a hollow shaft that is heated by dry steam; and
a plurality of additional conduction surfaces includes:
a plurality of hollow rings mechanically connected along a longitudinal axis of the hollow shaft that receive the dry steam from the hollow shaft to efficiently transmit heat to dry the predefined amount of waste in contact with the hollow shaft and the hollow ring; and
a set of return pipes connected to each hollow ring of the plurality of hollow rings, which return the dry steam from the plurality of hollow rings back to hollow shaft.
2. The apparatus for drying waste as set forth in claim 1 ,
wherein:
the one or more hollow members include:
a hollow shaft that is heated;
a plurality of additional conduction surfaces in a form of at least one hollow ring mechanically connected along a longitudinal axis of the hollow shaft that receive the heat from the hollow shaft to efficiently transmit heat to dry the predefined amount of waste in contact with the hollow shaft and the hollow ring.
3. The apparatus for drying waste as set forth in claim 1 ,
wherein:
a set of blocks externally connects the plurality of hollow rings to agitate and move the predefined amount of waste forward inside the heating chamber.
4. The apparatus for drying waste as set forth in claim 1 ,
wherein:
the tumbler assembly further includes a set of rigid reinforcement members linked to a hollow ring of the plurality of hollow rings providing added strength to the plurality of hollow rings.
5. An apparatus for drying waste, comprising:
a main frame positioned for providing a rigid support to the apparatus;
a heating chamber rigidly linked to the main frame;
a main inlet including a feed inlet section and a feed discharge section;
a predefined amount of waste is received via the main inlet and into the feed inlet section, and is transferred via the feed discharge section to a tumbler assembly of the heating chamber to dry the pre-defined amount of waste;
the tumbler assembly rotates at a predefined speed by a motor connected to a motor controller;
the tumbler assembly is comprised of a hollow shaft, which is connected to a steam inlet to receive dry steam at a predefined pressure;
the steam inlet directs dry steam inside the hollow shaft of the tumbler assembly, with dry steam existing the hollow shaft of the tumbler assembly via a steam outlet;
the tumbler assembly is further comprised of:
a plurality of hollow rings mechanically connected along a longitudinal axis of the hollow shaft that receive the dry steam from the hollow shaft to efficiently transmit heat to dry the predefined amount of waste in contact with the hollow shaft and the hollow ring; and
a set of return pipes connected to each hollow ring of the plurality of hollow rings, which return the dry steam from the plurality of hollow rings back to hollow shaft.
6. The apparatus for drying waste as set forth in claim 5 , wherein:
a set of blocks externally connects the plurality of hollow rings to agitate and move the predefined amount of waste forward inside the heating chamber.
7. The apparatus for drying waste as set forth in claim 5 , wherein:
the tumbler assembly further includes a set of rigid reinforcement members linked to a hollow ring of the plurality of hollow rings providing added strength to the plurality of hollow rings.
8. The apparatus for drying waste as set forth in claim 5 , wherein:
the tumbler assembly is connected to a rotating shaft of the motor to rotate the tumbler assembly.
9. The apparatus for drying waste as set forth in claim 5 , wherein:
the inlet steam includes a hollow inlet shaft.
10. The apparatus for drying waste as set forth in claim 5 , wherein:
the outlet steam includes a hollow outlet shaft.
11. The apparatus for drying waste as set forth in claim 5 , wherein:
the tumbler assembly is an enclosed mechanism with one entry opening for ingress of dry steam and one exist opening for egress of dry stream.
12. The apparatus for drying waste as set forth in claim 11 , wherein:
the entry opening for ingress of dry steam is a hollow inlet shaft and exist opening for egress of dry steam is a hollow outlet shaft.
