DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to Fig. 1, there is shown a construction of waste incinerating apparatus in accordance with a
3.5 preferred embodiment of the invention. As shown in this drawing, the waste incinerating apparatus includes an incinerator 30 which is provided with a heating wire 32.
The incinerator 30 contains lead Pb therein. The incinerator 30 is provided with a pressing plate 34. The pressing plate 34 will press down the wastes thrown into the incinerator 30, so that the wastes are immersed in the melted lead of the incinerator 30. A plurality of electromagnets 34A are provided on the bottom surface of the pressing plate 34. Placed under the incinerator 30 is a liquid collect tank 50 which will contain varieties of liquids therein. The varieties of liquids, which were dissolved in the melted lead of the incinerator 30 and floated on the surface of the melted lead, are contained in the tank 50 in multi-layers according to their specific weights. A plurality of liquid collectors 60 are connected to a side wall of the tank 50, so that the collectors 60 are leveled with the interfaces between the liquids contained in the tank 50 respectively. The top of the incinerator 30 is covered with an openable lid 36. The incinerator 30 is also provided with a pressure control cylinder 70 which will be operated by the gas pressure generated in the hermetically sealed incinerator 30 and controls the gas pressure of the incinerator 30.
Installation of the above waste incinerating apparatus is shown in Fig. 1. A horizontal wall 10 is holed so as to form a waste throwing hole defined by a side surface 12. The waste throwing hole is provided with an openable door 14 w ich is hinged to the surface 12 of the horizontal wall 10, so that the door 14 will be turned downwardly from the horizontal position to the vertical position and opened. A waste container 20 is mounted on the bottom surface of the horizontal wall 10. The container 20 is located under the waste throwing hole of the wall 10, so that the container 20 receives the wastes therein when the door 14 is opened. The bottom plate 22 of the container 20 is hinged to a side wall of the container 20, so that the bottom plate 22 is openable.
The incinerator 30 is located under the waste container 20, so that the incinerator 30 receives the wastes therein
when the openable bottom plate 22 of the container 20 is opened. The incinerator 30 is provided with the heating wire 32 in its side wall and in its bottom as described above. The pressing plate 34 hinged to the interior surface of the side wall of the incinerator 30 has a plurality of rectangular through holes 34b spaced out at regular intervals as shown in Figs. 2A and 2B. The pressing plate 34 is hinged to the incinerator 30, so that the plate 34 is immersed in the melted lead when the plate 34 is in the horizontal position.
The pressing plate 34 is a metal plate and is provided with the plurality of electromagnets 34A on the bottom surface. When the electromagnets 34A are turned on, the pressing plate 34 is magnetized. The top of the incinerator 30 is covered with the openable lid 36.
An outlet port 30A is formed in an upper section of the side wall of the incinerator 30. The outlet port 30A is connected to a liquid drain pipe 38 which in turn extends to the liquid collect tank 50. The tank 50 is provided with cooling chamber 52 in its side wall. The plurality of liquid collectors 60 are connected to the side wall of the tank 50 through their discharge pipes 54, so that the collectors 60 are leveled with the interfaces between the liquids contained in the tank 50 respectively. A gas exhaust port 30B is formed on the side wall of the incinerator 30 above the liquid outlet port 30A. The gas outlet port 30B is connected to a gas inlet of the pressure control cylinder 70. The cylinder 70 is provided with a gas outlet as well as the gas inlet. In the present invention, each of the liquid collectors 60 may be provided with a secondary cooling chamber.
The waste incinerating apparatus of the invention also includes a net strainer 90 of Fig. 3 about the incinerator 30. The net strainer 90 which is bent into U shape will be used for picking up the unburnt solid materials floating in the melted lead of the incinerator 30. The unburnt solid materials picked up by the net strain 90 will be collected
by additional means (not shown).
The incinerator 30 contains a predetermined amount of lead Pb therein as described above.
In the drawings, the reference numerals 39 and 55 denote valves respectively.
When starting the above apparatus, the heating wire 32 is turned on and heats the lead and melts the lead. After melting the lead in the incinerator 30, the openable lid 36 of the incinerator 30 is opened prior to turning the pressing plate 34 upwardly. After turning the plate 34 upwardly, the wastes heaped on the openable door 14 are dropped into the waste container 20 by turning the door 14. The wastes in turn are dropped into the melted lead of the incinerator 30 by turning the openable bottom plate 22 of the container 20.
Thereafter, the pressing plate 34 is turned downwardly so as to be located in its horizontal position. The plate 34 thus makes the wastes immersed in the melted lead and incinerated. During incineration of wastes, the synthetic resin materials such as PVC are melted into liquid phase and rise to the surface of the melted lead, while wood materials are burnt up so as to become charcoal. The other solid wastes, that is, the noncombustible stones or metals whose specific weights are lower than the specific weight of the lead float in the melted lead. The liquids above the pressing plate in the incinerator 30 are discharged from the incinerator 30 through the liquid outlet port 30A and flows in the drain pipe 38 so as to be collected in the liquid collect tank 50. At this time, the valve 39 is opened. The varieties of liquids are contained in the tank 50 in multi¬ layers according to their specific weights. After the liquids are contained in the tank 50, the valves 55 of the discharge pipes 54 connected to the side wall of the tank 50 are orderly opened in such a manner that the valve 55 of the uppermost pipes 54 is first opened and the valve 55 of the lowermost pipe 54 is last opened, the liquids of different specific weights are discharged from the tank 50 to their
collectors 60. The liquids collected by the collectors 60 may be reused. However, useless liquids are solidified so as to reduce the volume, thus to simplify waste treatment. The cooling chamber 52 of the liquid collect tank 50 cools the high temperature liquids contained in the tank 50.
The upper space of the incinerator 30 closed by the openable lid 36 is charged with gas generated by the wastes. The gas in the upper space of the incinerator 30 expands, so that the gas is discharged from the incinerator 30 through the exhaust port 30B and introduced into the pressure control cylinder 70 through the gas inlet of the cylinder 70. The gas acts on the bottom of the piston received in the cylinder 70, thus to push up the piston. The gas is, thereafter, exhausted from the cylinder 70 to the outside through the gas outlet of the cylinder 70. That is, the pressure of gas generated by the wastes in the incinerator 30 automatically closes or opens the gas inlet and the gas outlet of the cylinder 70, so that the gas pressure of the incinerator 30 is controlled and prevents possible breakage of the incinerator 30 due to high pressure.
In the present invention, it is preferred to connect gas collecting means to the gas outlet of the cylinder 70. In this case, the exhaust gas may be reused.
After incineration of wastes, the openable lid 36 is opened prior to turning on the electromagnets 34A of the pressing plate 34. The pressing plate 34 having the magnets 34A is turned upwardly, so that ferrous metals floating in the melted lead are attracted to the magnets 34A and stuck to the magnetized plate 34. Thereafter, the ferrous metals stuck to the plate 34 are separated from the plate 34 by turning off the magnets 34A and collected by metal collecting means.
Stones or aluminums which still float in the melted lead after the magnetic treatment for the ferrous metals are picked up by the net strainer 90. That is, the net strainer 90 of Fig. 3 is immersed into the melted lead in the incinerator 30 and moved horizontally and took out of the
melted lead, thus to pick up the stones or aluminums floating in the melted lead. The wood materials deformed into charcoal are reburnt in the bottom of the incinerator 30 using an additional burner, thus to save electric power for the heat wire 32 of the incinerator 30.
The metals having specific weights larger than the specific weight of the melted lead sink to the bottom of the incinerator 30. Such sunken metals may be picked up by a hook (not shown). As described above, the method and apparatus for incineration of wastes according to the present invention let varieties of wastes be thrown into the incinerator without classification of the wastes according to classes. In the incinerator of the invention, the combustible materials are burnt up so as to become liquids, while the noncombustible materials float in the melted lead of the incinerator. The liquids of the combustible materials are separately collected by liquid collectors according to their specific weights. The ferrous metals and nonferrous materials of the noncombustible materials floating in the melted lead are picked up and separately collected. In this regard, the method and apparatus for incineration of wastes of the invention readily treat the wastes and effectively collect reusable materials out of the wastes. Another advantage of the invention is resided in that the apparatus of the invention is simplified in its construction, thus to be reduced in its cost.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
