Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show the configuration of a garbage dewatering apparatus according to the present invention.

In FIG. 1, reference numeral 1 denotes a cylindrical body constituting a main body of the garbage dewatering apparatus.

The cylindrical body 1 is supported on the upper end of the mounting leg 2 erected on the installation floor G at an intermediate portion thereof by a pin 21 at a proper angle and inclined.

The inclination angle of the cylindrical body 1 supported by the mounting legs 2 can be changed as appropriate.

On the upper peripheral surface on the lower end side of the cylindrical body 1, there is formed an inlet 11 (see FIG. 2) for charging garbage.

A hopper 3 into which garbage is put into an input port 11
Are connected. The joint formed by the hopper 3 and the peripheral portion of the cylindrical body 1 forming the inlet 11 has an acute cross-sectional shape on the dust transport direction side as indicated by A in FIG.

On the lower peripheral surface on the lower end side of the cylindrical body 1, there is provided a perforated plate 12 composed of a wire mesh or a plate-like body having a plurality of through holes. A cover 13 is provided around the cylindrical body 1 provided with the perforated plate 12, and the cover 13 covers the outside of the perforated plate 12.

A water distribution pipe 14 communicated with the inside of the cover 13 is provided outside the cover 13. From the water distribution pipe 14, the juice put into the cylinder 1 together with the garbage is drained.

The water distribution pipe 14 is communicated with a sewer pipe or a drainage channel.

The perforated plate 12 and the cover 13 are configured to be detachable from the cylindrical body 1 so that maintenance and cleaning can be easily performed.

The lower end opening of the cylindrical body 1 is closed by a lower lid 15.

The upper end opening of the cylindrical body 1 is closed by an upper lid 4.

The upper lid 4 is formed by integrally forming a lid cylinder 41 having the same size as the cylindrical body 1 and an end plate 42 for closing the upper opening of the lid cylinder 41 by welding or the like. .

A discharge port 43 is formed on the lower peripheral surface of the lid tube 41.

The upper lid 4 having the above-mentioned structure is attached to a lower end of the lid tube 41 and an upper end of the cylindrical body 1 so that the outer peripheral edge of the upper lid 4 is removed from the outer peripheral surface of the upper lid 4 except for the discharge port 43. It is attached to the upper end of the cylindrical body 1 by being wound, and is firmly fixed with bolts and nuts (not shown).

A fixed blade 45 is provided inside the upper cover 4. As shown in FIG. 3, the fixed blade 45 has an upper end portion 46 extending radially in three directions at substantially equal intervals from a central portion as shown in FIG. 3, and a lower end portion 47 having the upper end portion as shown in FIG. It is appropriately extended downward from the center of 46.

The radially extended upper end 46 is integrally or detachably fixed to the inner surface of the upper lid 4 while straddling the discharge port 43.

The lower end portion 47 is formed by bending the lower end portion 47 into two, and when it is disposed in the cylindrical body 1 as shown in FIG. At the same time, the opening side is arranged to face the discharge port 43.

The fixed blade 45 is formed in a shape as described above, for example, from a steel plate having an appropriate thickness.

A ribbon screw 5 as a screw is disposed inside the cylindrical body 1.

The ribbon screw 5 has a relatively narrow cross-sectional shape, and has a diameter substantially equal to the inner diameter of the cylindrical body 1 and is spirally wound (1.5 turns in the figure), and the lower end is described later. While being connected to the driving device 6, the upper end is disposed so as to slightly project from the discharge port 43.

The driving device 6 includes a rotating plate 61 rotatably arranged on the bottom surface of the inner cylinder 1 and a driving motor 62 connected to the rotating plate 61 via a transmission mechanism 63.

The transmission mechanism 63 includes a rotation shaft 64 having one end fixed to the center of the rotation plate 61, a gear 65 fixed to the other end of the rotation shaft 64, and a transmission shaft fixed to the output shaft of the drive motor 62. And a pinion 66 meshed with the gear 65.

The other end of the rotating shaft 64 is guided through the lower lid 15 to the outside, and a middle portion thereof is rotatably supported by a support member 67 supported by the lower lid 15 via a bearing (not shown). Supported.

The drive motor 62 is supported on the outer surface of the lower cover 15 extending toward the hopper 3.

The driving device 6 thus configured drives the driving motor 62 to rotate, so that the rotating shaft 64 and the rotating plate 61 are rotated via the pinion 66 and the gear 65.
The ribbon screw 5 connected to the rotating plate 61 rotates in the cylinder 1.

The driving device 6 is protected by a cover 6a provided on the outer surface of the lower cover 15.

Here, the connection structure between the lower end of the ribbon screw 5 and the rotary plate 61 is configured as shown in FIGS.

More specifically, the lower end of the ribbon screw 5 is inserted between a pair of mounting pieces 68 provided on the peripheral upper surface of the rotating plate 61, and is supported between the mounting pieces 68 by the pins 69 in this state.

The lower end of the ribbon screw 5 is arranged with a predetermined gap between a pair of mounting pieces 68. Therefore, when the lower end of the ribbon screw 5 rotates to reach the lower side of the cylindrical body 1 as shown in FIG. 4, the outer end thereof rotates while sliding on the inner peripheral surface of the cylindrical body 1 by its own weight. It has been made like that.

The pin 69 and the pin hole at the lower end of the ribbon screw 5 supported by the pin 69 and the pin hole of the mounting piece 68 are connected so as to have a slight clearance (play). ing. Therefore, the ribbon screw 5 is supported in a state where the rotation direction is restricted, so that an unreasonable moment is not generated in the direction orthogonal to the axis of the pin 69.

Next, the operation of the thus configured garbage dewatering apparatus will be described.

Garbage from the employee cafeteria or restaurant is stored in a plastic bucket or the like, and is put into the bottom of the cylindrical body 1 from the hopper 3 through the inlet 11 by the plastic bucket.

In the cylindrical body 1, the ribbon screw 5 is rotated by the driving device 6, and is conveyed toward the discharge port 43 while being stirred by the rotation of the ribbon screw 5.

At this time, since the cylindrical body 1 is inclined, the garbage is conveyed upward while being pushed from below by the action of the ribbon screw 5, and is again moved downward from the narrow ribbon screw 5 in the cylindrical body 1. After being dropped and stirred, it is further conveyed toward the discharge port 43, and a part thereof is discharged to the discharge port 4.
3 and is discharged.

By repeating this operation, garbage is caught in the gap between the ribbon screw 5 and the inner surface of the cylindrical body 1,
The soup conveyed while being rubbed, and the juice put together with the garbage by this action is sufficiently separated from the garbage, and drained from the bottom of the cylinder 1 through the perforated plate 12, the gabber 13, and the water distribution pipe 14. At this time, the juice impregnated in the garbage is also dehydrated by the above-mentioned action, and the water of the garbage itself is also partially dehydrated.

The dewatering action of this soup is obtained when the amount of refuse is small or the operation time per unit amount of refuse (treatment time).
The effect is great when is long.

Here, since the inclination angle of the cylindrical body 1 is variable, the inclination angle is set to an optimum angle according to the quality of waste (for example, the amount of soup) and the operation time per unit amount of waste. can do. That is, when the inclination angle is increased, the processing amount is small, but the dewatering effect of the soup becomes high.

When garbage is put in a plastic bag, the hopper 3 and the cylindrical body 1 are connected to the plastic bag while the plastic bag is wound from the hopper 3 through the inlet 11 by the rotation of the ribbon screw 5. , And the front and side ends of the fixed blade 45 are torn off. Thereby, the garbage and soup inside are taken out of the plastic bag in the cylinder 1, and the above-mentioned dehydration processing is performed.

Furthermore, hard garbage such as cans and bottles may be mixed in the garbage. In this case, there is a possibility that the garbage may be caught between the ribbon screw 5 and the cylinder 1.

When such a hard object is bitten,
Since the rotation of the ribbon screw 5 is prevented, the load on the drive motor 62 of the drive device 6 increases. By detecting this increase, the ribbon screw 5 is rotated in the reverse direction for a certain period of time, and is rotated forward again to reduce the bite. Can be released. Also,
If the biting cannot be released even after repeating this operation, the rotation of the ribbon screw 5 is stopped, and
This situation is notified to the operator by an alarm or the like.

The worker who knows this removes the bite in the cylinder 1. This operation can be performed relatively easily by removing the top cover 4.

When a large amount of the above-described processing needs to be performed, the size of the garbage dewatering apparatus is increased, and the garbage is mechanically charged into the hopper 3 by an inverting charging device. By continuously connecting a conveying device such as a conveyor to the discharge port 43, continuous processing can be performed.

Further, it goes without saying that this garbage dewatering apparatus can be used at home.

[0055]

As described above, according to the garbage dewatering apparatus of the first aspect, the juice can be surely dewatered from the garbage with a simple configuration, and the subsequent work can be performed smoothly. Further, since the configuration is simple, there are few failures and troubles.

According to the apparatus for dewatering garbage according to the second aspect, even when the garbage is put in the state of bag garbage containing garbage in the bag, the bag garbage is removed by the sharp corner formed by the hopper and the cylindrical body. The bag can be reliably broken, and the dewatering process can be performed smoothly.

According to the garbage dewatering apparatus of the third aspect, the fixed blade is provided on the upper portion of the cylindrical body, so that the fixed blade can more efficiently break the bag garbage. Since the fixed blade is arranged across the discharge port, the garbage obtained by dehydrating the juice can be smoothly discharged from the discharge port without clogging the garbage.

According to the apparatus for dewatering garbage according to the fourth aspect, by changing the inclination angle of the cylindrical body according to the properties of the garbage, it is possible to carry out the optimum dewatering processing according to the situation.
