DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A waste oil treatment apparatus according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing a schematic configuration of a waste oil treatment apparatus according to the present invention, and FIG. 2 is A- of FIG.
It is an A line schematic sectional drawing.

In the figure, 1 is a first waste oil discharge device, 14 is a waste oil supply tank for supplying waste oil, and 6 is a plurality of holes for discharging waste oil. The first waste oil discharge device 1 is a conical cylindrical body that spreads toward the bottom surface, and has a plurality of holes 6 formed around the bottom and is rotated at a high speed by a motor.

The diameter of the holes 6 formed around the bottom and the arrangement interval of the holes differ depending on the type of waste oil treated by the apparatus according to the present invention, but normally the diameter of the holes is preferably about 5 mm to 15 mm, It is preferable to form them at intervals of about 3 cm to 7 cm in the circumferential direction.

In the first waste oil discharge device 1, the waste oil supplied from the waste oil supply tank 14 is disposed in the second waste oil discharge device 2 through a plurality of holes 6 with a strong force by centrifugal separation. Hit the quality wall 7.

Waste oil containing large solids must be removed by sieving the large solids before feeding to the waste oil supply tank 14.

Further, in the treatment by this apparatus, the edible waste oil and the mineral waste oil are treated separately, and the two are not treated by mixing them. The edible waste oil and the mineral waste oil that have been processed separately are collected, and the edible waste oil and the mineral waste oil are mixed and processed at a constant ratio in the fuel manufacturing apparatus according to the applicant of the present application.

Reference numeral 2 is a second waste oil discharging device, 7 is an inner porous peripheral wall, 8 is a filter cloth or filter paper, and 9 is an outer porous peripheral wall.

The second waste oil discharge device 2 is disposed outside the first waste oil discharge device 1 and rotates at a high speed by the same rotation shaft as the motor rotation shaft of the first waste oil discharge device 1. The second waste oil discharge device 2 has a cylindrical shape, and the upper part is opened,
As shown in FIG. 2, four shaft rods 10 that interlock with the motor rotation shaft are formed at the bottom.

The cross section of the shaft rod 10 formed on the bottom portion has a substantially trapezoidal shape that is tapered upward. This is because solid matter such as metal pieces removed from the waste oil easily falls into the storage container 5.

In the present embodiment, the case where four shaft rods 10 interlocking with the motor rotary shaft are formed has been described, but the number of shaft rods is not limited to this, and the shaft may vary depending on the type and amount of waste oil. Any number of bars can be used.

Further, in the present embodiment, the motor, which is the rotational drive source of the first waste oil discharge device 1 and the second waste oil discharge device 2, is arranged below the second waste oil discharge device 2. ,
The arrangement position of the motor is not limited to this, and it goes without saying that the motor may be arranged outside the device.

A filter cloth or filter paper 8 is provided in the second waste oil discharge device 2.
Porous peripheral walls 7 and 9 are formed on the inner side and the outer side with respect to each other. The filter cloth or filter paper 8 is for removing solid matter from waste oil and discharging only liquid waste oil. The filter cloth or filter paper used here is preferably a non-woven fabric.

FIG. 3 is an enlarged view of a part of the second waste oil discharge device 2. As shown in the drawing, the porous peripheral wall 7 on the inner side of the second waste oil discharge device 2 forms a large number of protrusions inward, and holes are formed at the tip of each protrusion. On the other hand, the outer peripheral wall 9 is formed with a large number of protrusions toward the outside, and holes are formed at the tips of the protrusions.

According to this structure, solid matters such as metal pieces adhering to the periphery of the inner porous peripheral wall 7 can be easily removed, and the outer porous peripheral wall 9 collects liquid waste oil from the waste oil storage device. You can exhale smoothly to 3.

The waste oil containing solid matter discharged from the plurality of holes 6 formed in the first waste oil discharge device 1 is the second waste oil.
Of the waste oil discharging device 2 is strongly struck by the inner peripheral wall 7 of the porous body, and liquid waste oil is formed in the numerous holes, the filter cloth or filter paper 8 and the outer peripheral wall 9 by the centrifugal action. It is guided to the waste oil storage device 3 through the hole.

Reference numeral 3 denotes a waste oil storage device, which is disposed between the second waste oil discharge device 2 and the outer frame member 13, has a cylindrical shape, and has a waste oil discharge port 11 which can be opened and closed.

The waste oil discharged and collected from the waste oil discharge port 11 is liquid without containing solid pieces such as fragments of fish, birds, vegetables, fried meal, metal pieces, silicon residues, tars and the like.

Reference numeral 4 is a solid substance removing device, and 12 is a brush. The removing device 4 is arranged inside the second waste oil discharge device 2, and the brush 12 is configured to be attached to and detached from the porous peripheral wall 7, and the rotation of the second waste oil discharge device 2 is performed. It is designed to rotate in conjunction with.

The brush 12 formed in the removing device 4 scrapes off the solid matter adhering to the periphery of the inner peripheral wall 7 and drops it into the container 5. Further, the removing device 4 prevents the numerous holes formed in the inner peripheral wall 7 for discharging the liquid waste oil from being blocked.

Reference numeral 5 denotes a storage container for storing the solid matter, which is disposed below the second waste oil discharge device 2 and has an openable / closable solid matter discharge port.

The storage container 5 adheres to the solid matter such as fried meal and the like which automatically falls from the second waste oil discharge device 2 and the periphery of the inner peripheral wall 7 and is removed and removed by the removing device 4. It accommodates incoming solids.

The contained solid matter may be discarded as it is because it contains almost no liquid due to the double centrifugal action as described above. However, fish, birds,
Debris such as vegetables can be used as fertilizer.

Further, since metal pieces, silicon residues, tars and the like contained in the mineral waste oil may harm the human body, it is necessary to be careful when disposing of them.

On the other hand, the waste oil collected from the waste oil discharge port 11 of the waste oil storage device 3 is a liquid containing no solid matter, and is low in price and high in quality by the fuel production apparatus and method disclosed by the applicant of the present application. It can be used as a raw material for producing fuel.

[0048]

According to the present invention, the edible waste oil and the mineral waste oil are suitably and conveniently treated to easily and surely separate and remove the solid matter from the waste oil, and the waste oil from which the solid matter is removed is recovered, It can be used as a raw material for producing high quality fuel at a reasonable price.
