Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a food waste processing device for drying so-called garbage such as food waste generated at home by using a rotary tank.

[0002]

[Prior art]

 Disposers, etc., have been conventionally known as devices for treating kitchen waste for household use.However, since sewerage facilities are still incomplete in Japan, it is forbidden to use the disposers, etc. to dispose of crushed kitchen waste into sewage. It is the actual situation. Therefore, in general households, kitchen waste is stored in a basket attached to the sink or a draining container attached to the sink, and if necessary, consigned to a garbage truck for disposal.

However, in such a treatment method, the kitchen waste must be stored at home for several days, during which the kitchen waste rots and gives off a bad odor, and when the kitchen waste is moved, sewage is spilled. There is a drawback. Therefore, in recent years, as an apparatus for treating such domestic food waste at home, an apparatus for drying by heating and an apparatus for dehydrating by centrifugal dehydration have been proposed.

[0004]

[Problems to be solved by the device]

 However, the heat treatment drying waste treatment equipment requires a large amount of equipment and requires energy such as electricity and gas as a heating source, which raises a problem that the treatment cost increases. On the other hand, the dehydration treatment device using centrifugal dehydration has a merit that the equipment can be simplified and the treatment cost is low, but it is difficult to remove the water held by vegetables and grains themselves in a short time, There was a problem that it could not be dried sufficiently, and it was difficult to completely discharge even the separated water that had been scattered in the casing and adhered to the wall surface, etc., and this residual separated water would decompose and cause a bad odor.

In view of such a point, the present invention makes it possible to dry kitchen garbage such as kitchen waste quickly and with a high drying rate with a simple device, and further, to dispose the garbage into the rotary tank. It is an object of the present invention to provide an apparatus for treating food waste that can be easily thrown in and cleaned inside the casing.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a casing in which forced ventilation means for forming a centrifugal air flow in a rotary tank is arranged, and a spacer member is detachably mounted inside the casing. An electric motor is fixed to the bottom wall portion of the spacer member, a rotary tank is detachably attached to the electric motor, and a separation water reservoir is formed on the upper peripheral edge of the rotary tank.

[0007]

[Action]

 In the present invention, since the rotating tank is detachably attached to the electric motor that is the driving means of the rotating tank, when the garbage is loaded, the rotating tank is removed from the electric motor and brought into the sink to bring the garbage into the rotating tank. It is possible to put the waste into the room, and it is possible to prevent the surroundings from being polluted by the water dripping from the waste when the garbage is put in.

[0008] Moreover, since the casing is provided with the forced ventilation means for forming an air flow in the centrifugal direction in the rotary tank, during the processing of food waste, it is subjected to centrifugal dewatering by rotation and the centrifugal direction formed in the rotary tank. This means that the air flow will carry out ventilation drying, and the garbage will be dried in a short time.

Further, since the separated water reservoir is formed on the upper peripheral edge of the rotary tank, the separated water separated by centrifugal dewatering at the time of rotation of the rotary tank accumulates in the separated water reservoir on the upper peripheral edge of the rotary tank. It will not be scattered outside, and the separated water that has accumulated in this separated water reservoir will come into contact with the air flow that is formed in the rotary tank to promote vaporization and dry early, so that it will remain attached to the wall surface. It will not rot.

Further, since the rotating tank and the electric motor that is the driving means for the rotating tank are supported by the spacer member that is detachably attached to the casing, the separated water may spill into the casing. Also, by removing the spacer member from the casing, the inside of the casing can be cleanly cleaned.

 FIG. 1 shows an embodiment of the present invention, FIG. 1 is a schematic configuration diagram of the present invention, FIG. 2 is a partially broken perspective view of a rotary tank, FIG. 3 is a vertical sectional view showing a structure of a rotary tank drive section, and FIG. It is an overall cross-sectional plan view. This food waste processing device includes an outer casing (3) formed by a rectangular tube-shaped main body (1) and a lid (2), a motor support base (4) arranged inside the casing (3). The electric motor (5) fixed to the motor support (4), the rotary tank (6) detachably engaged with the electric motor (5), and the rotary tank (6) are arranged inside the rotary tank (6). It is composed of a mesh tube (7).

The rotary tank (6) is composed of an outer cylinder (8) and an inner cylinder (9) fitted inside the outer cylinder (8). The inner cylinder (9) is shown in FIG. In this way, the peripheral wall is formed in a corrugated cross section in which the ridges (10) and the concave grooves (11) along the axis are alternately located, and a certain length near the upper end of the ridge is projected. A separate water reservoir (S) is formed by forming a circle having the same outer diameter as the strip. The inner cylinder (9) is constructed so that the tip end surface of the ridge (10) is inscribed in the inner peripheral surface of the outer cylinder (8) so that it can be fixed relative to the outer cylinder (8). The mesh cylinder (7) is arranged so as to be inscribed in the inner end of the concave groove (11) of the corrugated inner cylinder (9).

The bottom walls of the outer cylinder (8) and the inner cylinder (9) project upward in the shape of a truncated cone at the central portion. A large number of fins (12) are concentrically arranged on the outer surface of the bottom wall of the outer cylinder (8), and two ridges (13) are formed along the outer peripheral edge of the bottom wall of the outer cylinder (8). ) Are projected in parallel. On the other hand, in the motor support base (4) arranged to face the bottom surface of the outer cylinder (8), the upper end of the outer peripheral wall (14) is projected between the ridges (13) formed on the bottom wall of the outer cylinder (8). A cylindrical partition wall (15) is erected inside the outer peripheral wall (14) so as to face the fins (12) and the inside of the cylindrical partition wall (15) is formed. An outer peripheral chamber (17) is formed between the cylindrical partition wall (15) and the outer peripheral wall (14) in the motor housing chamber (16).

The motor support base (4) is vibration-isolated and supported by a support mechanism (19), which will be described later, on a spacer member (18) which is removably fitted into the main body portion (1) of the casing (3). . The spacer member (18) has a rectangular tube portion (20) internally fitted to the main body portion (1) of the casing (3) and a cylindrical portion (21) inscribed in the rectangular tube portion (20). The bottom wall of the casing (3) is arranged at a lower portion of the rectangular tube portion (20) and the cylindrical portion (21) with a proper distance from the bottom wall of the casing (3). The lower part of the space formed between the rectangular tube part (20) and the cylindrical part (21) communicates with the motor accommodating chamber (16) and the upper part communicates with the outer part of the casing (3). A space formed between the portion (21) and the rotary cylinder (6) housed inside the portion (21) is communicatively connected to the outer peripheral chamber (17).

Therefore, with the rotation of the rotary tank (6), the fins (12) formed on the bottom wall of the outer cylinder (8) act as a sirocco fan, and the outside air outside the casing (3) enters the casing (3). The open air inlet (23) is introduced into the motor housing chamber (16) through the space formed between the rectangular tube portion (20) and the cylindrical portion (21), where the electric motor (5) The cooling exhaust air is discharged from the outer peripheral chamber (17) to the space formed between the cylindrical portion (21) and the rotary cylinder (6) housed inside.

Further, the lid (2) of the casing (3) has a space between the cylindrical portion (21) whose inlet portion is formed in the main body portion (1) and the rotary cylinder (6) housed inside thereof. An air passage (24) is formed that communicates with the space formed in the space. The outlet of this air passage (24) is formed so that it slightly penetrates into the inside from the top opening of the rotary tank (6). I am doing it. Further, an air exhaust passage (25) communicating with the upper opening of the rotary tank (6) is formed in the lid body (2), and the air exhaust passage (25) is formed on the outer peripheral surface of the lid body (2). The air exhaust port (26) communicates with the outside of the casing (3).

Since the rotary tank (6) is formed by the outer cylinder (8) and the inner cylinder (9) having a corrugated cross section, the corrugated inner cylinder (9) is rotated by the rotation. It acts as a sirocco fan and sends out the motor cooling exhaust air that has flowed into the rotary tank (6) from the inside of the inner cylinder (9) to the gap between the mesh cylinder (7) and the inner cylinder (9). The motor cooling exhaust air sent into the gap between the cylinder (9) and the mesh cylinder (7) is discharged to the outside of the casing (3) from the exhaust passage (25) formed in the lid (2). Become.

The support mechanism (19) of the motor support base (4) forms a through hole in the bottom wall (22) of the spacer member (18) at a position corresponding to the motor rotation axis, and the through hole is formed. The support plate (28) is placed on the bottom wall (22) of the spacer member (18) so as to cover the lower side of the forming part, and the floating table (29) is attached to this support plate (28) via the spring (30). By arranging them, the floating table (29) is elastically biased upward, and the spherical vibration-proof rubber (31) is provided between the upper surface of the floating table (30) and the lower surface of the motor support table (4). In addition to arranging them, four peripheral support anti-vibration rubbers (32) are arranged at equal pitch on the circumference centered on this anti-vibration rubber (31) to respond to swing vibration of the rotary tank (6). It is configured as follows.

When the amount of garbage stored in the rotary tank (6) is larger than the set amount and the weight is over, the flow of the support plate (28) is restricted so as to limit the drive of the rotary tank (6). The limit switch (33) is fixed to the lower part of the stand (29). The elastic coefficient of the spherical anti-vibration rubber (31) placed between the floating base (30) and the motor support base (4) is set larger than the elastic coefficient of the peripheral anti-vibration rubber (32). There is.

Next, a procedure for processing food waste using the above apparatus will be described. The rotary tank (6) is removed from the main body part (1) of the casing (3), and an airtight synthetic resin bag such as polyethylene film is placed inside the corrugated inner cylinder (9) of the rotary tank (6). The mesh tube (7) is attached to the inside, and the garbage is put into the inside of the mesh tube (7) from the draining container to put the rotary tank (6) in the main body part (1) of the casing (3). Set inside. At this time, if a draining bag such as a mesh bag is attached to the draining container, remove the whole bag, or if the draining container is not attached to the draining bag, remove the garbage from the draining container. If it is housed in a water-permeable bag and installed inside the mesh tube (7), it will be easy to take out.

Then, after closing the lid body (2), a switch (not shown) is operated to operate the electric motor (5). As a result, the rotary tank (6) starts rotating, and the food waste contained in the rotary tank (6) is centrifugally dehydrated. At this time, since the inner cylinder (9) of the rotary tank (6) is formed in a corrugated cross-section, an air flow from the axial side toward the circumferential side is generated as the rotary tank (6) rotates.

Further, the fins (12) formed on the lower surface of the bottom wall of the rotary tank (6) take in outside air into the motor housing chamber (16), and at the same time, the air in the motor housing chamber (16) is drawn into the outer chamber (17). ), A cooling air flow is generated in the motor accommodating chamber (16) to cool the heat generated by the operation of the electric motor (5). Then, this cooling air is a space formed between the outer peripheral chamber (17) between the cylindrical portion (21) of the spacer member (18) and the rotary tank (6) housed therein, the lid (2). Garbage stored in the rotary tank (6) flows into the rotary tank (6) through the ventilation passage (24) formed in the inside of the rotary tank (6) and flows from the shaft core side to the circumferential side. Ventilate and dry.

At this time, at the beginning of the rotation of the rotary tank (6), the water is separated mainly by the centrifugal force, but when there is no water to some extent, the corrugated inner cylinder (9) is rotated to start the rotation. Draft drying by the air that has been blown begins, and the moisture that is carried between the garbage is transported to the outside. Dehumidification by this ventilation becomes more efficient because the contact area with the air becomes larger as the garbage becomes drier. Further, since the situation of food waste is reduced, the action of centrifugal force is reduced, and the adhesion of food waste to the peripheral wall of the mesh cylinder (7) is reduced, which further promotes the drying by ventilation.

In addition, the synthetic resin bag arranged along the inner peripheral surface of the inner cylinder (9) is in close contact with the inner surface of the inner cylinder (9) due to the centrifugal force and the air blowing effect accompanying the rotation of the rotary tank. The water discharged during the rotation moves upward through the inner peripheral surface of the synthetic resin bag at the protruding portion of the inner cylinder (9) and is stored in the separation water reservoir (S). Contacted and dehumidified. When the drying is completed, remove the dried refuse from the rotary tank (6) and treat it as burnable refuse.

In order to check the rotation speed of the rotary tank (6) and the drying rate of the food waste stored in the rotary tank (6), the rotation speed was set to 700 rpm and the air volume was set to 200 liters / min. It was changed to 1000 liter / min. The results are shown in Fig. 5 by the thin solid line and the thin dash-dotted line. From this result, it was found that the drying greatly progressed for several minutes at the initial stage of rotation (about 5 minutes in the experimental results), and thereafter the drying gradually proceeded. The drying rate in this case was compared with the total weight.

Then, using a rotary tank (6) whose air volume at 700 rpm is 200 liters / min and a rotary tank (6) which is 1000 rpm, the rotational speed is operated at 1600 rpm for 5 minutes in the initial period of rotation. Then, the speed was lowered to 700 rpm and the operation was continued. The results are shown by the thick solid line and thick one-dot chain line in FIG. As a result, it was confirmed that the drying rate was improved by about 10% in the same processing time as compared with the case where the continuous operation was performed at 700 rpm from the initial stage of rotation. When the operation was continued under the same conditions, the drying rate reached 30% 8 hours after the start of the operation.

[Effect of device]

 In the present invention, since the rotating tank is detachably attached to the electric motor that is the driving means of the rotating tank, when the garbage is loaded, the rotating tank is removed from the electric motor and brought into the sink to bring the garbage into the rotating tank. It is possible to dispose of the garbage in the surroundings and to prevent the surroundings from being polluted by the water dripping from the garbage when the garbage is added.

Moreover, since the casing is provided with the forced ventilation means for forming an air flow in the centrifugal direction in the rotary tank, during the processing of food waste, the centrifugal dehydration by rotation and the centrifugal direction formed in the rotary tank are performed. Since the air flow of this method will carry out ventilation drying, the food waste can be dried in a short time.

Further, since the separated water reservoir is formed on the upper peripheral edge of the rotary tank, the separated water separated by centrifugal dewatering at the time of rotation of the rotary tank accumulates in the separated water reservoir on the upper peripheral edge of the rotary tank. It will not be scattered outside, and the separated water that has accumulated in this separated water reservoir will come into contact with the air flow that is formed in the rotary tank to promote vaporization and dry early, so that it will remain attached to the wall surface. Can prevent corruption.

Further, since the rotating tank and the electric motor that is the driving means for the rotating tank are supported by the spacer member that is detachably attached to the casing, the separated water may spill into the casing. Also, by removing the spacer member from the casing, the inside of the casing can be cleanly cleaned.
