Abstract
An apparatus and method of separating small rubbish and organic matters from garbage for collection by means of water by considering specific weight, buoyancy, and flow rate of water is disclosed. The apparatus comprises a plurality of conveyor screens incorporating injection nozzles, a less inclined channel, a conveyor, and an organic matter screen for effectively separating floated rubbish, organic matters, and sunk rubbish from garbage for collection.

A method of separating small rubbish and organic matters from garbage mixed with water and with heavy materials removed therefrom comprising the steps of:
- sifting out small rubbish and organic matters by pouring the garbage mixed with water into screen means, passing organic matters and small rubbish through the screen means to an inclined channel, and pushing the garbage not sifted and stayed on the screen means to a next stage for processing by spraying water from injection nozzle means under the screen means;
- collecting sunk small rubbish by directing sand and the sunk small rubbish to a trough means in a bottom of the inclined channel and discharging sand and the sunk small rubbish out of the inclined channel for collection via a drain pipe;
- collecting floated rubbish on the inclined channel by transporting the floated rubbish on the inclined channel to a floated rubbish collection container for collection by an inclined conveyor having a lower portion sunk in water in the inclined channel;
- and
- sifting out the organic matters in water by directing water contained organic matters in the inclined channel to an organic matter screen for sifting out the organic matters and passing water through the organic matter screen for purification.
An apparatus of separating small rubbish and organic matters from garbage for collection comprising:
- a feed chute capable of moving in a vertical direction;
- a screen assembly below an outlet of the feed chute, the screen assembly including a first waterway at a bottom side;
- a inclined channel outside the screen assembly, and coupled to the first waterway, a junction of the inclined channel and the first waterway being at a highest position of the inclined channel, the inclined channel including an outlet at the other lowest end thereof,
- an organic matter screen below the outlet of the inclined channel;
- and
- a floated rubbish collection container for collecting floated rubbish,
- wherein the screen assembly further comprises:
- a first conveyor screen below and extended outward from the outlet of the feed chute, the first conveyor screen including a plurality of meshed openings and a bottom coupled to the first waterway;
- a tray below and extended outward from the first conveyor screen;
- a plurality of first injection nozzles under the first conveyor screen for obliquely spraying water toward surfaces of the first conveyor screen and the tray;
- a second conveyor screen below and extended outward from the tray, the second conveyor screen having a plurality of meshed openings equal to or larger than that of the first conveyor screen;
- and
- a second waterway at a bottom side of the second conveyor screen coupled to the inclined channel.
