Description

Description: TECHNICAL FIELD The present invention relates to a small diameter tube refuse pneumatic transportation system for collecting refuse generated in high and middle-rise buildings.

[Prior Art] In a method of collecting dust in a large-scale apartment house or office building, a centralized collection system combining a dust chute tends to be adopted instead of the conventional door-to-door collection system. In the chute, the noise of falling objects is significant and the chute tube is easily blocked by large and light dust such as corrugated cardboard. It is common to allocate dust chute of about the floor length to each block, and the waste accumulated in the storage tank at the bottom of each dust chute is regularly manually moved to the central storage facility using an elevator. It was being transported.

On the other hand, attempts have been made to substitute the air transportation for the periodical waste transportation by this input, connecting the storage tank at the bottom of each dust chute to the central storage tank with a pipe for air transportation, and Waste is sequentially transported by air to the central storage tank.

FIG. 2 shows an example of the configuration of a dust collection system that combines a dust chute and pneumatic transportation. In this conventional example, the crushers 3a to 3e provided for the dust chutes 2a to 2e, respectively.
Then, the dust thrown into the dust chutes 2a to 2e is crushed and dropped into the air flow in the small diameter transport pipes 4a to 4e to be mixed with air and transported by air.

Here, the crushers 3a to 3e are the dust chutes 2a to 2e.
Waste that has a wide variety of properties and shapes thrown into e
The small-diameter transport pipes 4a to 4e are cut into pieces suitable for air transport to facilitate the air transport.

In FIG. 2, a crusher 3a equipped with a temporary storage tank is provided at the lower end of the dust chute 2a installed in each block unit in the building, and the dust thrown into the dust chute 2a is stored in the temporary storage tank. It is stored, and is supplied to the crusher 3a at a predetermined speed and crushed at the same time as the crusher 3a is operated periodically. During operation of the crusher 3a, an air flow is always formed in the small-diameter transport pipe 4a to which the crusher 3a is connected to maintain a state in which dust can be received, and the shredded small-diameter transport pipe 4a is cut.
The dust that falls inside is immediately pneumatically transported to the central storage tank 6. Similarly, the dust chute 2b is provided with a crusher 3b and a small-diameter transport pipe 4b.
Crushers 3c-3e and small-diameter transport pipes 4c-4e are provided in c-2e, respectively.

On the other hand, the small-diameter transport pipes 4a to 4e for mixing the crushed wastes with the crushers 3a to 3e with air and transporting them to the central storage tank 6 by air transportation are equipped with valves at the terminals on the central storage tank 6 side. However, at the time of regular garbage collection, the garbage collection is performed in order by the small-diameter transport pipes 4a to 4e.
Open the corresponding valve, close it after a lapse of a predetermined time, and open the next valve.

Also, small-diameter transport pipes 4a-4 from the respective crushers 3a-3e
On the side of the central storage tank 6, e is connected to a separator 5 for separating only the waste from the mixture of the waste and the air. The lower end and the upper end of the separator 5 are respectively connected to a central storage tank 6 for storing separated dust and a dust collector 7 for removing fine particles from the separated air. Further, the blower 8 connected to the dust collector 7 is for driving the air flow of the entire system, and is operated only for a period in which the small-diameter transport pipes 4a to 4e are kept dust-receivable.

In the waste pneumatic transportation system of the conventional example, the dust thrown into the throw-in port 1a of the dust chute 2a falls in the dust chute 2a and accumulates in the temporary storage section provided at the lower end thereof to collect dust regularly. When the crusher 3a is operated, the dust is crushed by the crusher 3a, falls into the small-diameter transport pipe 4a, and is pneumatically transported to the separator 5 in a mixed state with air.

In the separator 5, the air and dust are separated again, the dust is stored in the central storage device 6, and the air is collected by the dust collector 7 and the blower 8.
And then returned to the atmosphere.

[Problems to be Solved by the Invention] In the small diameter tube refuse pneumatic transportation system described above, one crusher 3a to 3d is provided for each dust chute 2a to 2d.
And a small-diameter transport pipe 4 that can independently form an air flow with a valve, etc.
a to 4e are required.

The present invention has been made in view of these problems, and an object thereof is to provide a small-diameter pipe refuse pneumatic transportation system in which the number of crushers is reduced and the piping system of the small-diameter transportation pipe is simplified. .

[Means for Solving the Problem] The present invention collects dust in a plurality of dust chutes provided for each hierarchical block of a building through a chute pipe to a storage and discharging means at the bottom of the building, and finally A waste pneumatic transportation system that collects air intensively from storage means by means of pneumatic transportation, and from the dust chute of each hierarchical block to the storage discharge means, waste is collected through temporary storage means provided between each hierarchical block. A system for forming a gravity drop is formed, a crusher for crushing waste into small pieces is connected only to the outlet of the storage and discharge means, and a downstream side from the outlet of the crusher is configured as a collection system that pneumatically transports the waste through a piping system. Has been done.

[Operation] In the small diameter pipe refuse pneumatic transportation system of the present invention, each level block in the building is provided with a dust chute, and the dust thrown into each charging port in each level block is in this dust chute. To descend. On the other hand, dust from the dust chute of the high-rise block is dropped to the low-rise block through the chute pipe.However, if the fall distance of the dust is long, noise is significant and the pipe line may be blocked. Is used to divide the fall distance of garbage.

The dusts from the dust chute and the chute pipe are merged with each other and supplied to a common crusher, but the dust is supplied to the crusher at a predetermined speed by the storage and discharge means. The crusher crushes the trash into small pieces suitable for pneumatic transportation and supplies the crushed waste to the transportation / collection means.The transportation / collection means mixes the crushed waste with air and transports it to the center through a pipe system by air transportation.
