The accommodating part 61 is configured to store the liquid discharged from the drum selector 1 and passed through the cooler 42. The accommodating part 61 is formed of a predetermined material with a predetermined shape, but preferably has a hollow cylindrical shape. It is made of metal material.

The liquid inlet pipe 62 is connected in communication with the receiving portion 61 and is discharged from the drum selector 1 and passes through the cooler 42 to supply the heated liquid.

The oil discharge pipe 63 is connected to the receiving portion 61 to discharge the oil separated from the receiving portion 61 to the outside, the one side of the oil discharge pipe 63 to control the opening and closing The valve 63a is provided. The oil discharged from the oil discharge pipe 63 is used as bio oil.

The water discharge pipe 64 is connected in communication with the receiving portion 61 is configured to discharge the water separated from the receiving portion 61 to the outside, the control to control the opening and closing on one side of the water discharge pipe (64) The valve 64a is installed. As shown in FIG. 14, since the liquid contained in the accommodating part 61 is separated by the oil D being positioned above and the moisture E being located below by the difference of specific gravity, the accommodating part 61 is separated. One end of the oil discharge pipe 63 positioned in the interior of the accommodating portion 61 is located above the one end of the water discharge pipe 64 located in the accommodating portion 61 of the accommodating portion 61. Is located underneath. As the liquid containing oil and water has a higher temperature, oil and water are better separated, and the liquid separated in the drum separator 1 is heated through the cooler 42 and then supplied to the oil and water separator 6. Therefore, the oil and water separation efficiency can be improved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as falling within the scope of.

Claims (5)

In the drum sorter which separates the liquid and solid components from the food wastewater generated from food waste,
The drum selector includes a filter drum into which food waste water is introduced and a plurality of liquid discharge holes are formed on an outer surface thereof; A driving unit to rotate the filter drum and move the solid component separated inside the filter drum; Located at the outside of the filter drum at a predetermined interval, the high pressure washing nozzle for spraying a high pressure washing liquid toward the liquid discharge hole for a predetermined period of time;
The drive unit includes a drive motor for providing a driving force for rotating the drive shaft, a drive shaft connected to the drive motor at one end thereof, and a filter drum and a spiral plate connected to an outer side thereof, and an outer surface of the drive shaft positioned inside the filter drum. A spiral plate formed in a spiral shape,
The high-pressure washing nozzle is located at the outer side of the filter drum at a predetermined interval, the washing liquid inlet pipe connected to the washing liquid supply device and the washing liquid is supplied, and a plurality of through-holes are formed at a predetermined interval on the outer surface of the washing liquid inlet pipe to wash the washing liquid. It includes a washing liquid spraying hole for spraying the washing liquid inside the inlet pipe toward the liquid discharge hole,
As the filter drum is rotated by the driving unit, the liquid component from the food wastewater introduced into the filter drum is discharged to the outside of the filter drum through the liquid discharge hole, and only the solid component remains inside the filter drum. Since the high pressure washing nozzle sprays a high pressure washing liquid toward the liquid discharge hole for a certain period of time, it is possible to prevent the solid component from being caught in the liquid discharge hole.
