Abstract

(57) [Summary] [Purpose] To enable efficient and low-cost transportation of dust in an apparatus that transports dust transported by an air transport pipe to air and then transports it to a waste site using a vehicle. [Structure] A volume reducer 9 is connected to a dust separator 3 connected to an air transport pipe 1, and the volume of dust separated from air is reduced by the volume reducer 9 to reduce the volume to a fraction. Since the volume-reduced dust does not expand due to springback, it can be transported by using a normal flat-body type truck 23.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for collecting and storing garbage by pneumatic transportation.

[0002]

[Prior art]

 In urban redevelopment and construction of large buildings, transportation devices that collect and store garbage by air transportation are beginning to be adopted in order to stably and efficiently collect large amounts of garbage.

As shown in FIG. 5, this dust pneumatic transportation device is provided with a plurality of dust input ports 2 in an air transportation pipe 1 which is installed underground, in a common ditch, or under the floor of a building. The transport pipe 1 is configured by connecting a dust separator 3, a dust remover 4, a deodorizer 5, and a blower 6. The dust introduced into the air transport pipe 1 from the inlet 2 is sucked into the air by the blower 6. After being transported and separated from the air by the dust separator 3, the separated dust is sent to the dust storage and discharge device 7.

The waste sent to the waste storage and discharge machine 7 is loaded directly into the waste collection vehicle, or as shown in FIG. 5, the waste is packed into the container 32 by a waste compressor (compactor) 31 installed on the ground. After being compressed, it is loaded onto a dedicated container car 33 and transported to an incinerator or the like.

[0005]

[Problems to be solved by the device]

 However, as described above, the garbage trucks and various container trucks used for transporting dust have a limit in the weight and volume of the dust that can be loaded, and in order to transport a large amount of dust, it is necessary to carry it back and forth repeatedly. Therefore, there is a problem that the transfer efficiency is poor.

Further, since the dust compressed by the dust compressor 31 returns to its original state by springback when the pressurized state is released, the compressed state is maintained in the container vehicle 32 that conveys the dust after compression. There is a problem in that the vehicles that can be used are limited because special equipment is required to do so.

[0007] In addition, the garbage trucks and various container trucks used for transporting the garbage need to have special bodywork for transporting the garbage, so that the vehicle cost tends to increase. I have a problem.

Therefore, the present invention solves the above problems and provides a dust pneumatic transportation device capable of efficiently transporting dust without using a vehicle or a dust compressor having special equipment. Is intended.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention connects a dust separator and a blower to an air transport pipe having a plurality of dust input ports, and sucks the trash injected into the air transport pipe from the input ports by air suction by the blower. In the air transport device of Gomi, which transports air by means of a dust separator to separate air and dust, the volume separator reduces the volume of the dust separated by the dust separator so that it does not sprinkle back. This is the structure in which

[0010]

[Action]

 As described above, the volume of the dust is reduced to a fraction by the volume reducer, so that the dust can be transported with a small number of transports.

Further, since the dust reduced in volume by the volume reducer does not spring back, it can be transported by using an ordinary vehicle without special pressurizing equipment, and the facility for the dust compressor is not required.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The basic structure and operation of the pneumatic transportation device of this example are the same as those of the conventional structure described above, the same parts are designated by the same reference numerals, and the description thereof will be omitted. I will explain about this.

That is, in this embodiment, as shown in FIG. 1, a volume reducer 9 is connected to the discharge port 8 at the lower end of the dust separator 3 so that dust separated from the air by the dust separator 3 is continuously fed. And put it into the volume reduction machine 9.

As shown in FIGS. 2 to 4, the volume reducing machine 9 has two screw shafts 11 and 12 arranged in parallel inside a horizontal barrel (outer cylinder) 10. A drive device 13 is connected to each screw shaft 11, 12 to rotate them in opposite directions.

On the surface of each of the screw shafts 11 and 12, there are formed screws 14 and 15 which are twisted in different directions of right-handed and left-handed, respectively. When is rotated in the opposite direction, it has a function of sequentially sending out the dust introduced from the inlet 16 at the end of the barrel 10.

A tapered cone screw portion 17 is provided at the front ends of the screw shafts 11 and 12, and a narrowed portion 18 is formed between the starting point of the cone screw portion 17 and the barrel 10. Further, between the cone screw portion 17 and the taper portion 19 provided at the front end of the barrel 10, a compression portion 20 having a constant cross-sectional area of the throttle portion 18 is formed.

In the volume reducing machine 9 having the above structure, when dust is introduced from the inlet 16 while the screw shafts 11 and 12 are rotated, the dust is discharged to the front discharge port 21 by the action of the screws 14 and 15. While being sent toward, and passing through the squeezing portion 18 and the compressing portion 20, the volume is gradually compressed by the squeezing effect due to the reduction of the cross-sectional area and the friction resistance.

In the air transportation apparatus of the embodiment having the above structure, as shown in FIG. 1, the dust transported in the air transportation pipe 1 is reduced in volume after being separated from the air by the dust separator 3. It is put into the machine 9 and fed inside the barrel 10 by the screw shafts 11 and 12. The dust sent between the barrel 10 and the screw shafts 11 and 12 gradually decreases in cross-sectional area while passing through the throttle portion 18 and the compression portion 20, and is reduced to a volume of a fraction. .

The dust whose volume has been reduced by the volume reducer 9 does not spring back even if the pressurized state is released and does not expand to the original state. Therefore, as shown in FIG. It can be loaded onto a normal flat-body type truck 23, and can be transported using the truck 23.

Further, since the volume of dust is reduced to a fraction of the size, even a large amount of dust can be transported to an incinerator or the like with a small number of transports.

In the above embodiment, the volume reducer 9 has two screw shafts, and the bulge has a throttle portion and a compression portion at the tip thereof, but the volume reducer has a structure. However, the present invention is not limited to this, and a volume reducing machine having another arbitrary structure can be used as long as it has a function of reducing the volume of dust without springback.

[0022]

【effect】

 As described above, according to the present invention, the volume of the dust transported by air is reduced by the volume reducer, and the volume is reduced without the swingback. It is possible to transport dust with, and it is possible to greatly improve the dust transport efficiency.

Further, since the volume-reduced dust does not spring back, there is no need to use a dust collection vehicle or container truck with a special pressurizing equipment for transportation, and a dust compressor or the like can be dispensed with. The cost can be reduced.
