Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a garbage storage device.

PRIOR ART

In general, in mid-to-high-rise buildings, etc., in order to centrally dispose of garbage and garbage, the garbage dropped into the dumping port provided on each floor is guided through a dust chute and temporarily stored in a garbage storage device, and then the garbage is stored in a garbage storage device. The waste is transferred from the equipment to a garbage disposal vehicle.

Conventionally, rotary drum type devices have often been used as such garbage storage devices. That is,
The dust that falls into the rotating drum from the dust chute through the inlet is stored in the rotating drum.
Then, it is moved toward the discharge port by the rotational force of the rotating drum and is deposited and stored. At the time of discharge, the rotary drum is further rotated to send the garbage toward the discharge port, and the garbage is sent onto the transfer device from the discharge port with the discharge lid opened. The garbage is transferred from the transfer device to the garbage disposal vehicle.

[Problem that the invention attempts to solve]

However, the conventional device described above has the following disadvantages.

That is, the dust that falls into the rotating drum from the dust chute often stagnates near the input port.
As a result, a lot of noise is generated when the garbage falls,
Furthermore, in order to prevent the input port from being blocked, the rotary drum must be frequently rotated to send the garbage toward the discharge port, resulting in an extremely large amount of power consumption. Further, transferring the garbage toward the discharge port by rotating the rotary drum is merely a positional movement, and it is not possible to perform primary processing such as crushing the garbage. Moreover, the garbage transferred toward the discharge port is gradually compressed toward the discharge lid, and even if the discharge lid is opened during discharge, the discharge port is often blocked due to a bridging phenomenon. In order to prevent this bridging phenomenon, the volume of the rotating drum must be increased. Therefore, the installation area of the device becomes large, and the entire garbage processing system becomes large and expensive.

The present invention was developed in view of these points, and it prevents the garbage from stagnating near the input port.
Garbage can be stored while undergoing primary treatment,
The purpose of the present invention is to provide a dirt storage device that has high storage efficiency, low power consumption, and is inexpensive.

[Means for solving problems]

In order to achieve the above object, the present invention has a rotary drum having an inlet connected to a dust chute at the rear end and an outlet for discharging accumulated dust to a transfer device at the front end.The rear end is higher than the front end. In the garbage storage device, which is provided with a discharge lid that opens and closes the discharge port, only on the inner surface of the rotary drum near the discharge port, when the rotary drum rotates in the normal direction, garbage is pushed out in the discharge direction, and when the rotary drum rotates in the reverse direction, the garbage is pushed out. A spiral blade is provided to push back the garbage in the direction of the input port, and a sensor is provided near the input port of the rotating drum to detect when the garbage is temporarily full,
This device is characterized in that the rotating drum is temporarily rotated in reverse only when this sensor is activated.

[Effect]

According to the present invention, when garbage is thrown into the interior of the rotating drum, which is placed so that the rear end is higher than the front end, from the input port side at the rear end, the garbage slides down inside the rotating drum due to its own weight and reaches the tip. Move to the outlet side. When the rotary drum temporarily becomes full with the input garbage, a sensor provided near the input port is activated, and the rotary drum starts rotating in the reverse direction. Then, the garbage is pushed back toward the input port side by the spiral blade, and the garbage that is pushed back and the garbage that moves toward the front end inside the rotating drum due to its own weight are separated from the rotating drum at the rear end side where the spiral blade is not provided. They collide and knead each other inside. As a result, the garbage is compressed and crushed, the amount of garbage in the rotating drum is reduced, and a new space is formed inside the rotating drum, which is temporarily full, on the input port side, into which garbage can be input again.

〔Example〕

1 to 7 showing embodiments of the present invention will be described below.

As shown in FIG. 1, the device of the present invention is installed in a processing chamber 2 at the bottom of a building 1 such as a medium-to-high-rise building. A foundation 3a installed from the floor of the processing chamber 2,
An underframe 4 is provided on the underframe 3b at a slight inclination with respect to the horizontal plane, and bearings 5a, 5 are mounted on the underframe 4.
A rotary drum 6 is provided via b so as to be rotatable in forward and reverse directions. Each of these bearings is formed by, for example, supporting a tire 7 fixed to the outer periphery of a rotating drum 6 by a radial support roller 8 provided on an underframe 4, as shown in the bearing 5a on the left side of FIG. has been done.
The rotating drum 6 is provided so that the leading end (left end in FIG. 1) of the rotating shaft C is low and the rear end (right end in FIG. 1) is high. An input port 9 is provided at the rear end of the rotating drum 6, and the input port 9 is communicated with the lower end of a dust chute 10 provided in a building. Further, a discharge port 11 for discharging dust is provided at the tip of the rotating drum 6, and the discharge port 11 is opened and closed by a discharge lid 13 attached to an arm 12 that swings in the direction of arrow d in FIG. I am made to do so. Further, a driven gear 14 is fixed to the outer periphery of the rotating drum 6 on the input port 9 side.
4 is meshed with an output gear 16 of a rotary drive device 15 that rotates the rotary drum 6 in forward and reverse directions. Further, the dust thrown in from the dust chute 10 can slide down the inner surface of the rotating drum 6 from the input port 9 to the vicinity of the discharge port 11, that is, the inner surface of the input port portion 6a and the central portion 6b, to the discharge port portion 6c. formed into a shape. In this embodiment, the inlet portion 6a is formed into a tapered shape that widens toward the end, and the central portion is formed into a cylindrical shape, and both inner surfaces are finished smooth. On the other hand, on the inner surface of the discharge port portion 6c, there are blades that push the garbage toward the discharge port 11 when the rotary drum 6 rotates forward, and push the garbage back toward the input port 9 when the rotary drum 6 rotates in the reverse direction. In the example, the spiral blade 17,
17 are provided. A transfer device 18 is provided in front of the discharge port 11 to send the garbage discharged from the discharge port 11 into a collection warehouse of a garbage processing vehicle or the like. As shown in FIGS. 1 and 2, this transfer device 18 is formed of an outer cover 19 having a substantially W-shaped cross section and a pair of screw conveyors 20, 20 provided at the bottom of the outer cover 19.

Next, the operation of this embodiment will be explained.

As shown in FIG. 3, the rotating drum 6 is kept stationary during normal times, and the dumping port 2 provided on each floor is
1 to garbage dumped in the dust chute 10 2
2 falls within the dust chute 10 and enters the rotating drum 6 through the input port 9. This rotating drum 6
Since the inner surfaces of the inlet part 6a and the central part 6b are smoothly continuous with the dust chute 10, the dust 22 does not stop near the inlet 9 but slides down the inlet part 6a and the central part 6b due to the inertia of falling. Then, it is guided to just before the discharge port 6c.

Therefore, since the dust does not stay at the input port 6a, there is no need to frequently rotate the rotary drum 6 as in the conventional case, and generation of large noise when the dust falls is also prevented.

Thereafter, the garbage 22 continues to be dumped, and when the garbage 22 fills the central part 6b and the input port 6a as shown in FIG. 25 is activated to energize the motor 23 of the rotary drive device 15,
The rotating drum 6 is reversed.

Then, as shown in FIG. 5, the garbage 22 is given a force directed toward the discharge port 11 by the rotational force of the rotating drum 6, and is also given a force directed toward the input port 9 by the spiral blade 17. will be granted at the same time.
Therefore, the garbage collides with each other near the spiral blade 17, mixes with each other, and is circulated in the direction of arrow e in FIG.
Subject to compression and crushing action. Then, the volume of the garbage gradually decreases, and a new space is formed on the input port side of the rotary drum 6 into which the garbage can be input again.

After the rotating drum 6 rotates in reverse for a certain period of time, it is stopped, receives the garbage 22 again, and repeats the operation of rotating in the reverse direction due to the operation of the detection micro switch 25.

When the rotating drum 6 rotates in reverse, the spiral blade 17
Since the device pushes the garbage 22 back toward the input port 9, the volume reduction efficiency of the garbage is extremely high compared to conventional devices, and a large amount of garbage 22 can be accommodated. Further, the spiral blade 17 also prevents the garbage 22 from being strongly pressed against the discharge lid 13, so that when the garbage 22 is compressed, a bridging phenomenon does not occur at the discharge port unlike the conventional device. Therefore, the load on the discharge lid 13 is reduced, there is no need to increase the strength of the opening/closing device for the discharge lid 13, and the discharge port 11 can be reliably sealed, making it extremely hygienic. .

When the rotary drum 6 is full of garbage 22, as shown in FIGS. 6 and 7, the motor 23 of the rotary drive device 15 is energized to rotate the rotary drum 6 in the forward direction, and the discharge lid 13 is opened. It is opened and the screw conveyor 20 is rotated.

Then, the garbage crushed, compressed, and reduced in volume by the circulation action in the center of the rotating drum 6 is transferred to the discharge port 6, which has a relatively large space, due to the reversal effect of the rotating drum 6.
They are mutually unraveled at the portion c, and are successively dropped onto the outer cover 19 of the transfer device 15 by the extrusion action of the spiral blade 17 without blocking the discharge port 11.

Dust 2 from this discharge port 11 onto the outer cover 19
Since the rotary drum 6 is rotating, the delivery in step 2 is biased toward either one of the discharge ports 11. However, as shown in FIG. 7, for example, by reversing the rotational direction f of the screw conveyors 20, 20 from the rotational direction g of the rotating drum 6, the dust 22 that has fallen onto the outer cover 19 can be removed from the outer cover 19. It spreads out in the opposite direction toward the tip, allowing it to be fed while being loosened uniformly. As a result, the garbage 2 is transferred from the transfer device 18 into the garbage processing vehicle 24.
2 can be sent out without stacking them on one side.

Further, since the outer cover 19 prevents the dust 22, sewage, etc. discharged from the rotating drum 6 from scattering, the dust can be transferred hygienically.

After the garbage 22 is discharged, the discharge lid 13 is closed again, and the rotary drum 6 is again used for storing garbage.

[Effect of idea]

The garbage storage device of the present invention is configured and operates in this way, so when the amount of garbage thrown in increases, the sensor is activated and the rotating drum rotates in the opposite direction, causing the garbage to be pushed back by the spiral blades and the rotating drum due to its own weight. The garbage moving from the inside toward the tip collides with each other and mixes with each other, and the full garbage is forced to undergo compression and crushing action. Therefore, the storage efficiency is extremely high, and the garbage discharge is also easy. The process can be carried out smoothly without causing any phenomena, the power consumption is small, the entire device can be downsized, and the cost is low.
