Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air transportation facility for an object, which is provided in a building such as an apartment house, for transporting an object such as dust generated in the apartment house by using an air flow.

[0002]

2. Description of the Related Art As an air transportation facility for such an object, there is, for example, a dust air transportation facility as shown in FIG.

That is, a suction fan (not shown) is provided on the lower floor of a building 1 such as an apartment house (for example, a basement), and a transport pipe 2 for transporting an object (dust) by its suction force is connected to the suction fan. A storage port 5 is provided on a floor above the transport pipe 2 for loading an object to be loaded into the transport pipe 2, and a storage tank 5 connected to the transport port 4 for temporarily storing the dumped waste. And a discharge valve 3 that hermetically shields the storage tank 5 and the transport pipe 2 from each other, and the transport pipe 2 is provided upstream of the discharge valve 3 of the transport pipe 2 (opposite to the suction fan). An intake valve 6 that opens and closes is provided.

In this case, as shown in FIG. 4, in a normal state, the discharge valve 3 and the intake valve 6 are closed (see FIG. 4A).
(See reference) Waste is thrown in through the inlet 4 and temporarily stored in the lower storage tank 5. When the dust is discharged, the intake fan 6 is operated (see FIG. 4B), the intake valve 6 is opened (see FIG. 4C), and the airflow in the direction indicated by the arrow in FIG. 3 is secured. After that, the discharge valve 3 is opened (see FIG. 4D), and the dust in the storage tank is pneumatically transported to the collection destination.

[0005]

However, the conventional pneumatic transportation equipment for objects has the following problems because the intake valve 6 is provided at the end of the transportation pipe upstream of the discharge valve 3.

That is, the exhaust valve 3 is required to have high airtightness, and the structure of the exhaust valve 3 becomes complicated.

If the discharge valve 3 is made airtight, waste water generated from dust in the storage tank 5 collects at the upper part of the discharge valve 3,
This may cause dust to adhere and malfunction.

Negative pressure due to activation of the suction fan is applied to both the exhaust valve 3 and the intake valve 4, and both require a robust valve structure.

Further, since the intake valve 6 is provided at the end of the transport pipe 2, the total length of the equipment becomes long, a large installation area is required, and the space cannot be effectively used. .

The present invention has been made in view of the above circumstances, and the shielding means between the input port and the transport pipe can be a simple mechanism, and an object is prevented from adhering to the shielding means or a failure. An object of the present invention is to provide a pneumatic transportation facility for an object, which can be prevented and can be reduced in installation area and can effectively utilize space.

[0011]

The object pneumatic transportation system according to claim 1 of the present invention is an object pneumatic transportation system for transporting an object by an air flow, wherein suction means is provided and suction force by the suction means is provided. A transport pipe through which an object is transported, an input port connected to this transport pipe for inputting an object, and an openable and closable device arranged between the input port and the transport pipe to shield the input port and the transport pipe And a suction valve provided closer to the suction means than the shielding means of the transport pipe.

According to a second aspect of the present invention, there is provided the pneumatic transportation system for an object according to the first aspect, wherein the shielding means is opened between the charging port and the shielding means. A storage unit for temporarily storing the object is provided.

An object pneumatic transportation facility according to a third aspect of the present invention is characterized in that, in the pneumatic transportation facility for the object according to the second aspect, the storage portion is formed to extend vertically.

An object pneumatic transportation facility according to a fourth aspect of the present invention is the object transportation facility according to the third aspect, in which the inlet is provided on a predetermined floor of a building and is located below the floor. The storage section is provided on the floor.

An object pneumatic transportation facility according to a fifth aspect of the present invention is the object pneumatic transportation facility according to any one of the first to fourth aspects, wherein the object is dust.

[0016]

According to the object pneumatic transportation equipment of the present invention, the shielding means and the intake valve are normally closed, and an object such as dust is thrown in through the charging port. When transporting an object, first, the suction means is driven to open the intake valve to secure the air flow in the transportation pipe, and then the shielding means is opened to throw an object such as dust into the transportation pipe and transport it to the destination by the air flow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air transportation facility for objects according to an embodiment of the present invention will be described below with reference to the drawings.

Suction means (not shown) is provided on the lower floor of a building such as an apartment house (for example, a basement). As the suction means, a suction fan or the like is used.

A transport pipe 12 for transporting an object by the suction force of the suction means is connected to the suction means. An input port 14 for inputting an object (trash) is provided on the upper floor of the building, and a storage for temporarily storing the object input from the input port 14 is provided below the input port 14. The part (reservoir) 15 is connected. The lower end of the storage section 15 is connected to the transportation pipe 12.

A freely openable / closable shielding means 1 for shielding the storage part 15 and the transport pipe 12 between the storage part 15 and the transport pipe 12.

Normally, the shielding means 13 and the intake valve 16 are closed (see FIG. 2A), and an object such as dust is thrown in through the charging port 14. When transporting an object, first, the suction means is driven (see FIG. 2B) to open the intake valve (see FIG. 2).
(See (c)), after securing the air flow in the direction indicated by the arrow in FIG. 1 in the transport pipe 12, the shielding means 13 is opened (see FIG. 2).
(See (d)), an object such as dust is put into the transportation pipe and transported to the transportation destination by the air flow.

According to the present embodiment, the intake valve 16 is provided closer to the suction means than the shielding means 13, so that the following effects can be obtained.

Airtightness is required only for the intake valve 16, and the shielding means 13 can be a simpler mechanism than the conventional exhaust valve 3.

Further, since the shielding means 13 does not have to be airtight, it is possible to prevent sewage from collecting above the shielding means 13. Therefore, it is possible to prevent dust from adhering to the vicinity of the shielding means 13 and reduce failures caused by this.

Further, since the negative pressure generated by driving the suction means is applied only to the intake valve 16, the shielding means 13 can be a simple mechanism.

Further, since the intake valve 16 is provided in the middle of the transportation pipe 12, a dedicated installation space for the intake valve 16 is not required, and as a result, the transportation pipe 12 of the equipment is provided.
Can be shortened, and the installation area of equipment can be reduced.

That is, the length l of the terminal portion of the transportation pipe 2 in the conventional pneumatic transportation equipment shown in FIG. 3 is reduced as indicated by the symbol L in FIG. 1, and the installation area of the equipment can be reduced. Further, the distance m from the terminal of the transportation pipe 2 of the conventional air transportation equipment to the wall of the building can be made small as indicated by the symbol M in FIG. 1, and the effective use of the space in the building can be achieved. You can
