Abstract

PROBLEM TO BE SOLVED: To improve the agitation efficiency of crude refuse and to prevent the biting of the crude refuse to agitation vanes for agitation of the crude refuse by mounting the agitation vanes to a revolving shaft projectingly disposed at the center in the bottom of a heating vessel in such a manner as to be nearly perpendicular to the base surface of the heating vessel or to have a dull angle therewith. SOLUTION: The crude refuse is fed into the heating vessel 2 where the crude refuse is crushed under agitation by the agitation vanes 3 and is heated by a heater 16 by which the crude refuse is reduced in volume. At this time, the atmosphere gas A generated in the heating vessel 2 is passed through a condenser 8 and is separated to liquid W and gas G. The gas G is returned via a feed-in pipe 28 by a blower 6 into the heating vessel 2. On the other hand, the liquid W is sent from a gas-liquid separation vessel 9 to a tank 27 and is then successively discharged. In such a case, the agitation vanes 3 are mounted at the base surface 10 of the heating vessel 2 as to be nearly perpendicular to the base surface 10 of the heating vessel 2 or to have a dull angle therewith. As a result, the agitation rotating power of the agitation vanes 3 is surely transmitted to the crude refuse and the scooping of the crude refuse by the agitation vanes and the rolling thereof on the surface are eliminated.

A stirring blade 3 for stirring and crushing the garbage is provided inside the container 15. The stirring blade 3 is attached to a rotating shaft 4 protruding from the bottom of the heating tank 2. In addition, a motor 11 for rotating the rotating shaft 4 and the stirring blade 3 is provided below the heating tank 2.

An opening 18 serving as an outlet for the atmospheric gas A inside the heating tank 2 is formed in the upper part of the heating tank 2, and a suction pipe 19 constituting a part of the circulation path 7 is connected to the opening 18. Have been.

The condenser 8 in the circulation path 7 has a meandering pipe 21 provided with plate-shaped radiating fins 22, and a cooling fan 23 provided on a side surface thereof.
The atmosphere gas A sucked from the heating tank 2 is cooled by the suction air C.

The cooling fan 23 may cool the condenser 8 by compressed air instead of suction air C. Further, the cooling method of the condenser 8 is not limited to the air-cooling method, but may be a water-cooling method.

The gas-liquid separation tank 9 is formed in a closed box shape. A gas inlet 24 into which the atmospheric gas A cooled by the condenser 8 flows is formed in the upper part of the side surface, and the gas inlet 24 is formed in the upper part. A gas outlet 25 for discharging G is formed, and a liquid outlet 26 for discharging the condensed liquid W downward is formed at the bottom. The liquid W discharged from the liquid discharge port 26 is temporarily stored in a tank 27 provided at a lower part of the gas-liquid separation tank 9, and is sequentially discharged outside the apparatus.

On the downstream side of the blower 6, there is provided an inlet pipe 28 which constitutes a part of the circulation path 7, and the inlet pipe 28 is an opening which serves as an inlet for gas G formed on the side surface of the heating tank 2. 29.

According to the present invention, the agitating blade 3 is formed at a substantially right angle or an obtuse angle with respect to the bottom surface 10 of the heating tank 2 on the rotating shaft 4 protruding from the center of the bottom along the axis of the heating tank 2. It is characterized in that it is mounted as follows.

In the present embodiment, the stirring blade 3 is
As shown in FIGS. 2 and 3, the heating tank 2 is attached to the rotating shaft 4 so as to be perpendicular to the bottom surface 10 of the heating tank 2.

The stirring blade 3 is made of stainless steel and has a substantially rectangular side surface.

The two stirring blades 3 are radially attached to the rotating shaft 4 at equal angles (180 ° pitch). The number of stirrer blades 3 is not limited to two, but may be three. In this case, the opening angle between the adjacent stirring blades 3 is 120 ° pitch.

The stirring blade 3 is attached to the lower side of the rotating shaft 4, and its height h is almost twice the height that the garbage in the heating tank 2 occupies when it is in a uniform flowing state. Is set to be equal to

The stirring blade 3 is formed in a flat plate shape so that its outer peripheral side is backward with respect to its normal rotation direction (indicated by an arrow in the drawing). Tank 2
Is formed so as to have a gap 13 extending to the vicinity of the inner peripheral wall 12.

The stirring blade 3 does not tilt backward,
It may be arranged along the radial direction from the center of the rotating shaft 4. Further, the stirring blade 3 may have a shape in which the outer peripheral side is curved rearward in the normal rotation direction, instead of the straight flat plate shape as described above.

At the center of the stirring blade 3, an escape window 5 through which garbage in the heating tank 2 passes during its rotation is provided.

Next, the operation of the garbage disposer according to the present invention will be described.

The raw garbage is put into the heating tank 2 and crushed while being stirred by the rotation of the stirring blade 3.
The weight and the capacity are reduced by being heated by the heat of the water and gradually evaporating the water.

The atmosphere gas A generated in the heating tank 2
Is separated into a liquid W and a gas G condensed by passing through the condenser 8. Since an odor component is dissolved in the liquid W, the separated gas G has a reduced odor component.

The gas G passes through the inlet pipe 28 by the blower 6, is returned to the heating tank 2 again, and circulates.
On the other hand, the liquid W containing the odor component flows downward in the gas-liquid separation tank 9, is temporarily stored in the tank 27, and is sequentially discharged.

According to the present invention, the stirring blades 3 are attached so as to be substantially perpendicular or obtuse to the bottom surface 10 of the heating tank 2, so that the stirring blades 3 are surely stirred when the garbage is stirred. The rotating force is transmitted to the garbage, so that the garbage does not scoop on the stirring blades or roll on the surface as in the related art. Therefore, garbage can be efficiently stirred and crushed.

Further, since the stirring blades 3 are inclined backward in the rotation direction, the garbage is generated as the stirring blades 3 rotate.
It moves to the gap 13 on the outer peripheral side along the stirring blade 3 and is crushed as needed between the stirring blade 3 and the inner peripheral wall 12 of the heating tank 2.

Further, the inclination of the stirring blade 3 prevents the garbage from scattering and reduces the stirring resistance.

When the garbage is crushed, the garbage tends to escape upward. The height h of the stirring blade 3 is the height occupied when the garbage in the heating tank 2 is in a uniform flowing state. Since it is set to approximately twice, the garbage above can be effectively caught and the crushing efficiency can be improved.

The provision of the escape window 5 in the stirring blade 3 allows the garbage to escape backward in the rotation direction when the stirring blade 3 rotates, and the load applied to the motor 11 can be adjusted. Overload is not applied, and failures can be prevented.

Even when the motor 11 is rotated in the reverse direction, the stirring blade 3 is provided at a right angle or at an obtuse angle with respect to the bottom surface 10 of the heating tank 2.
The garbage does not bite into the space with the bottom 10 of the
Locking of the motor 11 can be prevented.

More specifically, as shown by the broken line in FIG. 3, when the stirring blade 3 forms an obtuse angle with respect to the bottom surface 10 of the heating tank 2,
A force F3 perpendicular to the surface is applied to the stirring blade 3 from garbage (indicated by a dashed line). This force F3 is converted to the horizontal force F
When the force F1 is smaller than the driving force of the motor 11, the motor 11 does not lock.

The smaller the angle α of the stirring blade 3 with respect to the bottom surface 10 of the heating tank 2, the greater the force F3. Therefore, the motor 11 is easily locked. However, by setting the angle α to a right angle or an obtuse angle, the force F1 is reduced. And locking of the motor 11 can be prevented.

At the same time, by reducing the force F3, the vertical force F2 is also reduced, and the stress for lifting the stirring blade 3 is reduced. Therefore, a bearing (not shown) for supporting the rotating shaft 4 The deformation of the stirring blade 3 can be prevented.

When the angle α of the stirring blade 3 with respect to the bottom surface 10 of the heating tank 2 is a right angle, the force F3 is minimized, so that the stirring blade 3 is at a right angle with respect to the bottom surface 10 of the heating tank 2. Is optimal.

Further, since the number of the stirring blades 3 is limited to three or less, the space between the stirring blades 3 becomes large,
At the time of switching between the normal rotation and the reverse rotation of the motor 11, the garbage that has been pushed by the stirring blades 3 is given a rotating force from the opposite side by the stirring blades 3 on the opposite side. At this time, the stirring blade 3 vigorously collides with the garbage that has been stopped, so that the impact promotes fine graining and improves the crushing effect.

The reason why the number of the stirring blades 3 is limited to three or less is that if the number is four or more, the space between the stirring blades 3 becomes small, and the garbage is clogged there and is rotated together with the stirring blades 3. This causes the above effects to not be obtained.

In the above embodiment, the stirring blade 3
Is formed in a flat plate shape, but is not limited thereto. For example, the lower portion may have a thick triangular cross section, or may have a surface provided with a number of protrusions for improving crushing efficiency.

[0052]

In summary, according to the present invention, by providing the stirring blade at a right angle or at an obtuse angle with respect to the bottom surface of the heating tank, the rotating force is applied to improve the efficiency of stirring and crushing the garbage, and the motor is improved. In the case of the reverse rotation, there is an excellent effect that biting into the stirring blade can be prevented.
