Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for collecting trash from a high-rise building.

Conventionally known techniques regarding garbage collection methods for high-rise buildings include Japanese Utility Model Publication No. 54-3580 and Japanese Patent Publication No. 52-28311. In all of these conventional methods, garbage is poured into a chute that penetrates from the top floor of a high-rise building to the underground processing room through the garbage inlet on each floor, either directly or indirectly through a sub-chute, and then falls into the underground processing room. It was designed to be collected. Therefore, these conventional methods have the advantage that garbage can be collected with high efficiency without using an elevator at all.

However, in all of these conventional methods, the garbage thrown into the chute from the garbage inlet is allowed to fall to the underground processing chamber in its current form. Therefore, in the case of bulky office waste, etc., accidents such as clogging during the chute are likely to occur, and once the clogging occurs, it is extremely difficult to clear it. In addition, clogging of the chute with debris is a serious cause of fire. In addition, the waste that is dropped into the underground processing room is reduced in volume using a compactor installed inside the underground processing room, which has some defects such as the need for a large compactor. Ta.

The present invention seeks to provide a method for collecting trash in high-rise buildings that can correct the above-mentioned deficiencies.

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

First of all, Figure 1 shows the entire garbage chute system of a high-rise building. 1F, 2F to NF indicate the first floor, second floor to the top floor, and B1F to NF indicate the first floor, second floor to the top floor.
BNF indicates the first basement floor to the lowest floor.

A main chute 12 is provided vertically penetrating between, for example, the underground processing chamber 11 provided on the bottom floor BNF and, for example, the top floor. In addition, on the ground floors 1F to NF, for example, there are subshoots 13a to 13a that vertically penetrate each of the 5th to 8th floors.
3n is provided. These sub-chutes 13a to 13n form a vertical line on the same side of the main chute 12, and the lower ends of each of these sub-chutes 13a to 13n are connected to the main chute 1 in an N-shape by an upwardly inclined passageway 14. It is connected. Note that the main chute 12 at the upper end of the slope of each ascending slope passage 14
Opening/closing valves 15 are provided at the connecting portions thereof, and garbage inlets 16 are provided for each of the ground floors 1F to NF in each of the subsuites 13a to 13n. Further, the lower end of the main chute 12 is directly connected to a garbage processing device 17 provided in the underground processing chamber 11.

Next, FIG. 2 shows details of the garbage storage crushing compressor 21 and on-off valve 15 provided at the connection between the main chute 12 and each sub-shute 13a to 13n, and the processing equipment 17 directly connected to the lower end of the main chute 12. This is what is shown.

First, a screw-type storage crushing compressor 21 is used, and a screw 22 for crushing and compressing garbage is connected to each sub-shute 13a to 13.
They are each rotatably housed in an upwardly inclined passageway 14 at the lower end of the tube. Note that this screw 22 ascends one end to reach the closed end 1 on the lower inclined end side of the inclined passage 14.
4a through a bearing 23 so as to be rotatably supported, and is configured to be rotationally driven by an electric motor 24 equipped with a reduction gear. And this storage crushing compressor 2
1 is configured to be activated based on the detection of the dust level by a contact type or non-contact type level switch 25 provided at a predetermined height position at the lower end of each sub-shute 13a to 13n. Incidentally, an impact relief plate 26 is provided at the lower end of each of the sub-chutes 13a to 13n, and at the lower end of each ascending slope passage 14 there is a residue receptacle or a residue bypass 2 which is bypassed to the main chute 12 as shown by the dotted line in FIG.
7 is provided.

Next, the on-off valve 15 is rotatably supported via a rotating shaft 31, and is positioned at a position where it closes the opening 14b at the upper end of each ascending slope passage 14 as shown by a solid line, and at a position as shown by a phantom line. The main chute 12 is configured to be swingable between a position in which the intermediate portion of the main chute 12 is closed. The on-off valve 15 is configured such that an arm 32 provided at one end of a rotating shaft 31 is driven by a drive mechanism such as an air cylinder 33 or a feed screw mechanism using an electric motor. Note that each of the garbage inlets 16 provided on each floor 1F to NF in each of the sub-shoots 13a to 13n is provided with a manual opening/closing lid 34, respectively.

Next, the processing equipment 17 includes, for example, a piston-type compactor 37, a hopper 38 connected to the upper part of the waste supply port 37a of the compactor 37 and directly connected to the lower end of the main chute 12, and a waste discharge port 37b of the compactor 37. The container 39 is connected to the side of the container 39. The compactor 37 is configured to be operated based on detection of the dust level by a contact or non-contact level switch 40 provided at a predetermined height at the lower end of the main chute 12.

Next, a description will be given of the garbage collection processing operation by the garbage chute device for a high-rise building constructed as described above.

First, on each of the ground floors 1F to NF, garbage is introduced into each of the subchutes 13a to 13n from the garbage inlet 16, respectively. The thrown-in garbage falls through each of the subchutes 13a to 13n and is stored in a storage crushing compressor 21 provided at the lower end thereof. That is, the garbage thrown into each of the subchutes 13a to 13n on each of the floors 1F to NF on the ground is stored in each storage crushing compressor 21 for every 5th to 8th floor. Incidentally, the impact of the fallen debris at this time is alleviated by the impact buffer plate 26.

On the other hand, at this point, the full open/close valve 15 is in the position shown by the solid line in FIG. 2, and closes the opening 14b of each ascending inclined passage 14.

In each storage crushing compressor 21, when the amount of dust stored there reaches a predetermined amount and the level switch 25 detects this, the electric motor 24 is operated for a certain period of time and the screw 22 is driven to rotate. . As a result, the accumulated dust is crushed into fine pieces in each upwardly inclined passageway 14, and is gradually pushed diagonally upward along the upwardly inclined passageway 14, and is then moved between the on-off valve 15 that closes each opening 14b. is compressed. That is, in each storage crushing compressor 21, the garbage put into each sub-shute 13a to 13n is automatically stored, crushed and compressed, and the volume of the garbage is reduced.

Next, when the garbage crushing operation in each of the garbage storage crushing machines 21 is completed, each on-off valve 15 is driven by the air cylinder 33, and each on-off valve 15 is moved to the position shown by the imaginary line in FIG. The opening 14b of each ascending slope passage 14 is opened, and the intermediate portion of the main chute 12 is closed. Then, each screw 22 is again driven to rotate for a certain period of time, and after each screw 22 pushes the garbage in each upwardly inclined passageway 14 diagonally upward once along the upwardly inclined passageway 14, it is released from the opening 14b. It is discharged into the main chute 12. The garbage discharged into the main chute 12 falls through the main chute 12 and is stored in a hopper 38 of a garbage processor 17 provided in the underground processing chamber 11.

However, at this time, the opening/closing operation of the full open/close valve 15 is system-controlled by a main control circuit (not shown) provided in the underground processing chamber 11.

That is, for example, as shown in FIG. 3, the on-off valves 15 of each of the sub-chutes 13a to 13n are opened and closed one by one, and for example, the sub-chutes 13a, 13c, 13e of the lowest stage, third stage, fifth stage, etc. ……
When the on-off valve 15 opens the opening 14b and closes the middle part of the main chute 12, the sub-shutes 13b, 13d, and the second stage, fourth stage, sixth stage, etc.
The on-off valves 15 13f... close the opening 14b. Next, the on-off valves 1 of the sub-chutes 13a, 13c, 13e of the lowest stage, third stage, fifth stage...
5 closes the opening 14b, the second stage, the fourth stage,
Subshots 13b, 13d, 13 of the 6th row...
The on-off valve 15 of f... opens the opening 14b and closes the intermediate portion of the main chute 12.

As a result of the above, the garbage compressed to a small volume and stored in each storage crushing compressor 21 is discharged into the main chute 12 one by one. Then, only the garbage discharged into the main chute 12 from the storage crushing compressor 21 at the lowest stage or the second from the lowest stage is directly dropped into the hopper 38, and is discharged into the main chute 12 from each storage crushing compressor 21 above it. The dust discharged into the main chute 12 is passed through each opening/closing valve 15 in the main chute 12.
After falling successively at heights of 5 to 8 floors while being caught by the hopper 38, it reaches the hopper 38.

Next, when the amount of garbage stored in the hopper 38 as described above reaches a predetermined amount, the level switch 40
When this is detected, the compactor 37 is operated for a certain period of time, and the dust in the hopper 38 is continuously fed into the container 39 by the compactor 37, thereby performing compression loading. At this time, the lowest stage or the second opening/closing valve 15 from the lowest stage closes the lower end of the main chute 12 and prevents the garbage from falling from the main chute 12 into the hopper 38. Therefore, there is no need to provide a gate valve between the lower end of the main chute 12 and the hopper 38. Further, after the compressed loading of the garbage is completed, the container 39 is suitably loaded onto a transport vehicle or the like and transported out.

However, according to the above-described garbage collection operation, the amount of garbage thrown into each of the subchutes 13a to 13n from the garbage inlet 16 on each floor is 5 to 8.
It is collected on each floor and stored, crushed, and compressed in each storage crushing compressor 21. By the system-controlled opening and closing operation of the on-off valve 15, the amount of garbage discharged from each storage crushing compressor 21 into the main shoot 12 is limited to the amount that can be stored in each storage crushing compressor 21 at one time, and the main shoot 12
Garbage compressed into a small volume is sequentially discharged inside. Then, inside the main chute 12, the garbage compressed into a small volume is sequentially dropped while being received by the on-off valve 15, and into the hopper 38 of the processing equipment 17, the amount stored at one time and compressed into a small volume is collected. of garbage is sent in and stored one after another.

Therefore, there is no possibility of debris bridging or clogging occurring in the middle of the main chute 12 or in the upper part of the hopper. Further, the hopper 38 is not clogged with garbage at all, and the garbage contained in the hopper 38 is compressed and loaded into the container 39 by the compactor 37 successively and efficiently.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various effective changes can be made based on the technical idea of the present invention.

As described above, the present invention automatically stores, crushes, and compresses the garbage thrown into the sub-chutes for each required floor of a high-rise building in each sub-chute. Then, the garbage, which has been previously stored, crushed, and compressed to a small volume, is discharged into the main chute.
Since it is made to fall through the main chute and be collected by the processing equipment, even bulky office waste can always fall extremely smoothly into the main chute. Therefore, it is possible to prevent accidents such as garbage clogging unexpectedly during the chute and causing a fire, and it is also easy to dispose of the garbage because the volume of the garbage is reduced in advance and collected by the processing equipment. It has the advantage that it can be sufficiently processed using a small compactor or the like.

Further, since the garbage is compressed as described above, a portion of the garbage remains at the lower end of the sub-chute and overhangs the inner wall of the main chute, so that in the event of a fire, there is almost no chance of guiding the fire into the sub-chute. Furthermore, the on-off valve works extremely effectively in preventing the above-mentioned fire from spreading to the sub-shute.
