Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage collection device that improves convenience, reduces transportation power, and makes it possible to lower the height of a basement floor of a building.

Conventional garbage collection devices for buildings and residential buildings include those equipped with a dust chute and a garbage can;
There are those equipped with a dust chute and a garbage storage and discharge device, etc. An example of a conventional garbage storage and discharge device that includes a dust chute and a garbage storage and discharge device is shown in FIG. c is a garbage inlet provided at a predetermined position on each floor surface of dust chute b, d is an exhaust pipe provided at the upper end of dust chute b, and e is connected to the lower end of dust chute b to the basement floor f of building a. This is the installed waste storage and discharge device. Although such conventional devices have a relatively simple structure, users who wish to discharge garbage from each floor must carry the garbage to the garbage input port C of the dust chute B, which reduces the level of service to users. not good.

Therefore, there is another example of a conventional garbage collection device equipped with a dust chute and a garbage storage/discharge device, as shown in FIG. 2, in order to solve the above-mentioned drawbacks. In the figure, g is a horizontal transport pipe stretched across the bottom of each floor to collect garbage from each floor, and h is a waste input storage that is installed in large numbers at predetermined intervals on the transport pipe g of each floor and has a discharge valve i at the bottom. In the device, j is an air pipe that extends vertically from the rooftop to the basement floor f, and one end of the transport pipe g is connected to the midway point, k is the intake pipe provided at the upper end opening of the air pipe j, and l is the top floor. A transport pipe that extends vertically from the surface part to the basement floor f, and the other end of the transport pipe g is connected to the midway part, m is a horizontal transport pipe connected to the lower end of the transport pipe l, and n is installed on the basement floor f. o is a waste storage and discharge device connected to the lower end of cyclone n for storing and discharging the waste removed by cyclone n; A bag filter s is connected to a bag filter q via a duct r to remove outside air from the bag filter s, and is connected to a bag filter q through a duct r, and sucks in outside air to transport the garbage thrown into the garbage storage device h on each floor. A blower capable of drawing air from cylinder k, t a silencer connected to blower s to reduce exhaust noise, and u a deodorizing device connected to silencer t to remove odor from the exhaust gas. Thus, such a garbage collection device is capable of disposing of garbage at multiple locations on each floor, and compensates for the drawbacks of the device shown in FIG. However, when transporting the waste, the waste is transported pneumatically even though it descends within the vertical transport pipe 1, which requires wasteful transport pressure and increases the power consumption of the blower s. In addition, mechanical devices such as silencer n, garbage storage and discharge device o, and bag filter q are stored on the basement floor f.
The height of the basement floor f will be higher than that shown in Figure 1, and the building construction cost will be high.

In view of the above-mentioned viewpoints, the present invention has been made with the aim of making it easier for users to use, reducing the transportation power of garbage, and lowering the height of the basement floor of a building where the garbage storage and discharge device is installed. It is.

The present invention has a diameter larger than that of the transport pipe and separates the air from the waste, and drops the separated waste by gravity onto one end of a horizontally installed transport pipe that transports the thrown waste by air. A vertical dust chute that also serves as a gravity settling tank is connected to the dust chute, and a blower, a silencer, and a deodorizing device are connected to the upper end of the dust chute via a bag filter, and a dust storage and discharge device is connected to the lower end of the dust chute. , the other end of the transport pipe is connected to a vertical air pipe having an intake pipe at its upper end.

Therefore, the garbage thrown into the transport pipe is transported through the transport pipe by the air introduced into the transport pipe from the suction cylinder through the air pipe, and enters the dust chute that also serves as a gravity settling tank.In the dust chute, the dust is The air is separated from the air and falls by gravity through a dust chute, accumulates in a dust storage device, and the air from which the dust has been separated rises through the dust chute to remove dust from the air, muffle sound, and deodorize before being discharged.

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

Figures 3 and 4 show an embodiment of the present invention, in which a horizontal transport pipe 2 is stretched around the bottom of each floor of a building 1, and the transport pipe 2 is passed through each floor to store waste. Connect device 3. A large number of garbage input and storage devices 3 are provided depending on the number of users on each floor. Further, a discharge valve 4 is provided at the bottom of each garbage input/storage device 3 to be opened and closed when discharging the garbage into the transport pipe 2.

Air pipes 6 extending vertically from the roof to the basement floor 5 are arranged at required positions in the building 1, one end of each of the transport pipes 2 is connected to the midway part of the air pipes 6, and the upper end of the air pipe 6 is An intake pipe 7 is disposed at the opening, and a dust chute 8 which also serves as a gravity settling tank and which extends vertically from the roof to the basement floor 5 in the same way as the air pipe 6 is disposed at a predetermined position within the building 1. The other end of each of the transport pipes 2 is connected to the side part of the middle part so that the axis of the normal cyclone is oriented in the tangential direction of the dust chute 8 which also serves as a gravity settling tank, as shown in FIG. The structure is such that the air fed from the air to the dust chute 8 which also serves as a gravity settling tank can rise while rotating spirally along the inner periphery of the dust chute 8 which also serves as a gravity settling tank. Also, the diameter d ₁ of the transport pipe 2
By setting the ratio of the diameter d ₂ of the dust chute 8 that also serves as a gravity settling tank to about d ₁ /d ₂ = 1/3 to 1/5, the flow velocity v ₁ of the air flowing in the transport pipe 2 and the dust chute that also serves as a gravity settling tank can be adjusted. The ratio to the flow velocity v ₂ of the air flowing inside 8 is
v ₂ /v ₁ = about 1/9 to 1/25 so that the dust falling in the dust chute 8 which also serves as a gravity settling tank is not entrained by the air rising inside the dust chute 8 which also serves as a gravity settling tank. That is, the diameter of the dust chute 8 that also serves as a gravity settling tank is determined so that the flow velocity v ₂ of the rising air in the dust chute 8 that serves as a gravity settling tank is smaller than the floating velocity of the dust.

The lower end of the dust chute 8, which also serves as a gravity settling tank, is connected to the garbage storage and discharge device 9 installed on the basement floor 5, and the bag filter 10, which is installed on the roof, is connected to the upper end of the dust chute 8, which also serves as a gravity settling tank, via an air pipe 11. The downstream end of the screw discharger 12 connected to the lower end of the bag filter 10 is connected to the upper end of the dust chute 8 which also serves as a gravity settling tank, and a structure that can be freely opened and closed is provided between the screw discharger 12 and the dust chute 8 which also serves as a gravity settling tank. A damper 13 is attached, a blower 14 disposed on the roof and the bag filter 10 are connected by a duct 16 equipped with an air intake valve 15, and the air discharged from the blower 14 is passed through a silencer 17 and a deodorizing device 18 to the atmosphere. Make it possible to release it.

Note that 19 in the figure is a garbage truck.

When performing garbage collection work, the blower 14 is driven, and air for garbage transportation is sucked from the intake pipe 7 through the air pipe 6 into the transportation pipe 2, and users on each floor can pick up the garbage from the nearest garbage disposal. Garbage is thrown into the storage device 3. Therefore, the predetermined garbage input storage device 3
When a predetermined amount of dust remains inside, the discharge valve 4 opens, the dust falls into the transport pipe 2, is carried by the air flowing through the transport pipe 2, flows through the transport pipe 2, and is directed to a dust chute 8 which also serves as a gravity settling tank. be introduced.

Since the flow rate of the rising air in the dust chute 8, which also serves as a gravity settling tank, is small, most of the garbage introduced into the dust chute 8, which also serves as a gravity settling tank, is separated from the transport air and is subjected to the action of gravity. Dust chute 8 that doubles as a gravity settling tank
The garbage falls inside, is stored in the garbage storage and discharge device 9, is loaded onto a garbage truck 19 as appropriate, and is transported to a garbage incineration plant. When the dust is introduced from the transport pipe 2 to the dust chute 8 which also serves as a gravity settling tank, the air flows in the tangential direction of the dust chute 8 which also serves as a gravity settling tank, so that the air does not flow into the dust chute 8 which also serves as a gravity settling tank. It ascends while turning in a spiral. Therefore, the centrifugal force caused by this swirling action effectively separates the dirt from the air. The air from which the dust has been separated rises in the dust chute 8, which also serves as a gravity settling tank, and enters the bag filter 10 through the air pipe 11, where the dust is separated and the air becomes clean. It is sucked from the duct 16 to the blower 14, pressurized by the blower 14, and then discharged to the silencer 1.
After the exhaust noise is reduced in step 7, the air passes through a deodorizing device 18, escapes, becomes pollution-free air, and is released into the atmosphere. In addition, the air flow velocity in the dust chute 8 which also serves as a gravity settling tank is the same as that of the conventional transport pipe l shown in Fig. 2.
The pressure drop (ΔP
∝v ₂ ² ) is very small, and the transport power of the blower 14 is very small compared to the blower s in FIG.

FIG. 5 shows another embodiment of the present invention, in which the upper end of a dust chute 8 that also serves as a gravity settling tank is directly connected to a bag filter 10.
With such a configuration, dust can be collected without providing a screw discharger or a damper. In the figure, the same reference numerals as those shown in FIG. 3 indicate the same components.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

According to the garbage collection device of the present invention, () users on each floor can throw their garbage into the nearest garbage storage device, so it is possible to improve the level of service to users and improve convenience; () The diameter of the dust chute that also serves as a gravity settling tank is increased to reduce the speed at which the air rises, and the dust is transported by falling due to gravity.
There is little pressure loss in the dust chute that also serves as a gravity settling tank, so the transport power of the blower is small.
Energy saving can be achieved. () Air and dust are separated in the dust chute that also serves as a gravity settling tank, and the dust is allowed to fall by gravity while the air is raised by power, making it possible to save energy by blower,
Mechanical devices such as filters, silencers, and deodorizing equipment can be installed on the roof instead of on the basement floor.
Therefore, various excellent effects can be achieved, such as being able to lower the height of the basement floor.
