Abstract

PROBLEM TO BE SOLVED: To provide a cleaning method which prevents the clogging of a draining hole of a garbage treating machine provided with a mesh filter for draining in its bottom and to provide a device for cleaning waste water by separating flushed away animal and vegetable fat and oil components. SOLUTION: The washing of the draining hole in the bottom is executed by releasing washing water from the front ends of agitating vanes for acceleration of the degradation by microorganisms and the fats and foils contained in the flushed away waste water are separated by a centrifuge, by which the waste water is cleaned.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for purifying waste water by filtering and decomposing animal and vegetable fats and oils contained in kitchen waste water and garbage pulverized by a disposer.

[0002]

2. Description of the Related Art Conventionally, garbage is crushed by a disposer, thrown into a garbage disposal container together with water, drained with a mesh filter for drainage provided in a lower part, and the garbage is stirred and decomposed by microorganisms. In the case of a garbage disposal machine, the drain hole in the lower part is clogged with animal and vegetable oils and fats and crushed garbage in the drainage, so the drainage hole cannot be reduced and most of the crushed garbage is drained. Along with it.

[0003]

The object of the present invention is to constantly wash this draining mesh filter to prevent clogging, to make the size of the mesh filter smaller than conventional draining holes and to minimize the outflow of crushed garbage. Further, animal and vegetable fats and oils that have flowed out together with the wastewater are separated by centrifugation to reduce the load on the wastewater.

[0004]

According to the present invention, as a means for preventing clogging of a drain hole, after crushed garbage is put into a treatment vessel together with water, the garbage is used for decomposing the garbage with microorganisms. Rotate several times while jetting the washing water from the tip of the stirring blade. The mesh filter for draining the lower part has a semicircular shape in accordance with the rotation of the stirring blade, and the tip of the stirring blade rotates while keeping the distance from the mesh filter of the lower part at about 5 mm to 10 mm. Animal and vegetable fats and oils attached to the pores are washed away each time. The animal and vegetable fats and oils that have passed through the mesh filter are sent to the next centrifugal separation tank, separated by centrifugation from the drain at the upper end, and returned to the original.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. FIG. 1 is a front sectional view of the garbage disposal container. In FIG. 1, a mesh filter 2 for draining is provided in a semicircular shape at a lower portion of a processing vessel main body 1. At the center thereof, there is a shaft 11 having a hollow inside, and further, the shaft 11 is connected with a stirring blade 3 for stirring the inside microbial inhabitants and garbage.

A rotary joint 10 is attached to an end of the shaft 11 via an electromagnetic valve 6 as shown in FIG. 2, and water is supplied to the rotating shaft 11. The supplied water is discharged as a shower due to the small slit at the tip of the stirring blade as shown in FIG. 3, and cleans the second mesh filter while rotating. The cleaning time is controlled by the solenoid valve 6 in accordance with the condition of the oil and fat.

The oils and fats which have been washed out and contained in the wastewater enter the water inlet pipe 25 of the composite rotary joint 27 of the rotating centrifuge and are discharged from the discharge part 21 at the tip. The discharged oil-containing water collects at the upper end of the rotating container due to the tapered shape of the container.
2 is discharged from the outlet. The water containing the discharged fats and oils at a high concentration accumulates in the fixed outer tank 28 and is returned to the garbage disposal container via the drain pipe 24.

The treated water from which animal and vegetable oils and fats are separated is 23
From the outlet through the discharge pipe 26 via the rotary joint 27.

[0009]

As described above, according to the method for cleaning a mesh filter for draining water according to the present invention, even if garbage is pulverized and put into a treatment container together with water, the drainage can be surely drained and the waste water can be placed in the decomposition tank. Without accumulation, the decomposition of garbage by microorganisms can be promoted. Furthermore, with the centrifugal separator of the present invention, wastewater can be purified by separating animal and vegetable oils and fats that have an adverse effect on the combined septic tank, river and sewer.

Claims (2)

[Claims] 1. A garbage crushed waste is put into a garbage disposal container together with drainage, and the drainage is filtered by a mesh filter for draining provided in a lower part, and the garbage remaining after filtration is stirred together with the microbial inhabitants in the treatment container. In a garbage disposal device that disintegrates by stirring with wings, washing water is spouted from the tip of the stirring blades in a way to prevent the lower drain mesh filter from clogging with animal and vegetable oils and fats contained in the wastewater. A garbage disposal apparatus equipped with a filter cleaning method, characterized in that the draining filter is washed while stirring and preventing clogging. 2. A method for separating animal and vegetable fats and oils and organic residue remaining in wastewater, wherein the wastewater is passed through a lower part inside the container while rotating a tapered container from an upper part to a lower part. The centrifugal force is characterized by taking out oils and organic residues floating and collecting at the upper end portion by centrifugal force from a drain port provided at an upper end portion, and further taking out separated water separated from oil and water from a drain port provided at an upper central portion. The garbage disposal device according to claim 1, further comprising a separation device.
