Description

[Detailed Description of the Invention] A waste pneumatic transportation device that transports urban, household, and office waste by carrying it in an air stream has a waste storage tank (1), a waste tank (1), and a waste tank (1) of the same type.
) connected to the transport pipe (3) and equipped with a discharge valve (2).
), separator (4), proa (5), etc., and the garbage (6) stored in the storage tank (1) is discharged from the air intake valve (not shown) by opening the discharge valve (2). The flow of air passes through the transport pipe (3), passes through the separator (4), and is collected in a recovery tank (force).
The air inside is sucked by the proar (5), passes through a filter, a silencer, and a deodorizing device (the collapse is not shown) and is released into the atmosphere as clean air as shown by arrow (8)K.

In the case of a conventional wide-area large-capacity garbage collection system, the diameter is 500 mm.
Transport pipes around 111F have been used. In order to apply this system to a 71% scale, small capacity system and reduce costs, it is effective to use small-diameter transport pipes with a diameter of 100 to 600 mm. can be realized.

In this case, to prevent the transportation pipe from being blocked by large pipes,
A crusher is installed at the entrance of the transport pipe (3).

Therefore, kitchen waste is turned into fine garbage with a high moisture content by this crusher, which may adhere to the bottom and wall of the transport pipe and cause blockage of the pipe.

The present invention has been proposed in order to solve these problems, and includes a garbage pushing spherical body that has elasticity and has a slightly larger diameter than the inner diameter of the air transportation tube for transporting the garbage. The present invention relates to a method for pneumatic transport of waste, which is characterized by pushing the waste forward and removing waste attached to the pipe or waste clogging the pipe.

In the present invention, as described above, a garbage pushing spherical body having elasticity and a diameter slightly larger than the inner diameter of the air transport pipe is used, and the spherical body is pressed into the transport pipe with pressurized air. Since the waste inside the pipe is pushed forward, the spherical body is pressed against the inner wall surface of the transport pipe and rubs against it, so that the waste that has adhered to the inside of the pipe and the waste that is blocked inside the pipe is removed, and together with the waste. It is transported along the inside of the tube, and therefore can be easily removed even if the tube becomes occluded.

The present invention will be described below with reference to the illustrated embodiments.

QB is a waste transport pipe, and there is a reducer Q′l on the upstream side of the pipe.
A blind plate frame equipped with a pressure gauge (14) and a pressurized air supply pipe (151) with a pressure gauge (14) and a pulp (1512) interposed therein. is installed.

In the figure, (I7) is a crusher installed near the entrance of the transport pipe Ql), QB is a discharge valve, and near a is a waste pushing coarse spherical body discharge port.
Kan is Zorua, QB is the separator, and Q-bu is the collection tank.

The garbage pushing spherical body 03) is made of paper, vinyl sheet,
A cloth bag, a plastic bag, or a polyethylene bag filled with polyethylene film or the like is formed into a spherical, rough ball, or cannonball shape, and is configured as an elastic body with a diameter slightly larger than the inner diameter of the transport pipe (11). .

Note that this may be made of soft polyethylene.

Since the illustrated embodiment is configured as described above, the branch part of the transport pipe (111) is sealed with the discharge valve [12+], and the space between the waste pushing coarse spherical body discharge port 09 and the separator 3D is Make sure there is no near leak, then open the valve (15α) and connect the reducer (12) through the pressurized air supply pipe (151).
When pressurized air is introduced into the interior, the waste pushing spherical body αJ pushes the waste up to the separator 3υ, and during that time the transport pipe U
A device that presses against the inner wall surface of υ and scrapes it, removes dirt stuck inside the pipe Ql) and debris (6') blocking the pipe α1), and pushes these along with the trash thrown into the pipe. It is.

As described above, according to this embodiment, even if a blockage occurs in the waste transport pipe aυ, it can be easily removed using a simple mi.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
