Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for more efficiently collecting dust generated in a factory by type.

[0002]

2. Description of the Related Art With respect to a dust collector, various inventions and inventions have been proposed in order to cope with improvement of working environment (for example, Japanese Utility Model Laid-Open No. 3-26319, Japanese Patent Laid-Open No. Sho 56-56).
-166916). Therefore, a conventional dust collecting method and dust collecting apparatus will be described with reference to the drawings. FIG. 4 is a conceptual diagram of a dust collecting system that implements a conventional dust collecting method, and FIG. 5 is an explanatory diagram of individual dust collectors. The dust a generated from the pollution source A in the hood 10 passes through the duct 12 and is sucked into the large-sized dust collector 20 from the horizontal duct 14. Similarly, the dust b generated from the pollution source B and the dust c generated from the pollution source C also flow into the horizontal duct 14 from the duct 12 connected to each hood, and the dusts a, b, and c of each type are mixed. Is sucked into the large dust collector 20.

[0003]

However, the above-mentioned conventional dust collector copes with the change of the layout of the equipment in the factory by extending or modifying the existing duct as shown by the broken line in FIG. As a result, the balance of setting the air volume is disturbed, and the length of the duct is increased, which causes the inconvenience of dust accumulation in the horizontal duct. Furthermore, it was difficult to remove the dust accumulated in the horizontal duct. In addition, the ducts that have been conventionally used have a large diameter of 1000 mm and a small diameter of 200 to 300 mm.
With such a large diameter pipe, by arranging such a large diameter and long duct, there is a feeling of pressure in the factory and natural lighting in the factory is disturbed, which deteriorates the working environment. Was there.
In addition, even though the dust collected in the large duster contains a large amount of reusable materials, the dust is collected in a mixed state, so the dust composition cannot be guaranteed. Instead, it was treated as industrial waste without being reused.

Therefore, the present invention provides a dust collector with a simple layout and a high dust collection efficiency, which makes it possible to easily reuse the dust by separately collecting dust in the factory for each type. It is a thing.

[0005]

A dust collector of the present invention collects dust generated from a pollution source in a factory for each type by a dust collecting means provided adjacent to the pollution source and collecting the dust. A configuration is provided in which the collected dust is connected to a plurality of pumping and collecting means provided for each system according to the type of dust.

[0006]

The dust generated from the pollution source is collected by type by the dust collecting means provided for each pollution source, pumped, and collected by type.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described with reference to the drawings. 1 and 2 are conceptual diagrams of a dust collector (system) for carrying out the present invention, and FIG. 3 is an explanatory diagram of a small dust collector.

Dust a generated from the pollution source A in the hood 50 is sucked into the first small dust collector 55 having a suction function by the fan 54 provided. The first small dust collector 55 is arranged at a short distance from the hood 50, and is connected to the first small dust collector 55 via a duct 52 having a short size. The first small dust collector 55 is equipped with a filtering means such as a filter. The dust a that has been sucked and entered the first small dust collector 55 is separated by the filtering means, and the clean air is discharged to the outside of the machine. The dust a in the first small dust collector 55 separated by the filtering means is collected in the first air transport tank 56 and sent to the air transport device 57. Source B of pollution
To the second small dust collector 6 at a short distance from the pollution source B.
5 are connected. The dust b generated from the pollution source B is sucked into the second small dust collector 65 through the duct 62, and the filtered and cleaned air is discharged to the outside of the machine, and the dust b is collected in the air transport tank 66. And sent to the air transportation device 67. Similarly to the pollution source C, a third small dust collector 75 is arranged adjacent to the pollution source C and is connected by a duct 72. The dust c generated from the pollution source C is sucked into the third small dust collector 75 through the duct 72 and filtered, and the dust c is collected in the air transport tank 76 and sent to the air transport device 77.

Inside the factory, an air transport device 57 for transporting the dust a, an air transport device 67 for transporting the dust b, and an air transport device 77 for transporting the dust c are provided as air transport devices. The air transportation device 57 is connected to the air transportation pipe 58 of the first small dust collector 55 connected to the pollution source A, and the air transportation device 67 is connected to the air transportation pipe 68 of the second small dust collector 65 connected to the pollution source B. And a third small dust collector 7 connected to the pollution source C to the air transportation device 77.
5 air transportation piping 78 is connected. As the piping used in this case, a tube having a diameter of 150 to 250 mm is sufficient. In the dust collecting system configured in this way, one small dust collector 55 (small dust collector 65 or 75) is provided for each pollution source A (B or C), and the dust collected by the small dust collector is a source of pollution. The same number of the air transport devices, in this embodiment, the air transport devices 57, the air transport devices 67, and the air transport devices 77 provided corresponding to the three types of pollution sources are collected for each type of dust and are pumped.

The case of changing the layout in the factory will be described. For example, the pollution source A is increased by 2 places. For one increased pollution source A ', a small dust collector 55' is added adjacent to the pollution source A '. Then, the air transportation duct is extended to connect the small dust collector 55 '. Further, another increased pollution source A ′ can be easily dealt with by inserting and arranging a small dust collector 55 ′ as shown by the broken line in the air transportation duct 58. As described above, the dust collecting system embodying the present invention can easily cope with changes in the layout of the factory, and furthermore, the air transportation piping arranged in the factory is a small-diameter tube body, which is easy to arrange. At the same time, the layout of the factory is tidy and the working environment is improved without disturbing the visibility and lighting. In addition, the collected dust has a high constituent purity and can improve the utility value. Note that the present invention can be economically implemented by replacing the air transportation device with the air transportation tanks 56, 66, and 76 into a closed tank and transporting the tank by transportation means such as a truck and a forklift. it can.

[0011]

In the dust collecting apparatus of the present invention, since a small dust collecting means is arranged adjacent to each pollution source, the distance for conveying the dust is short, and the dust can be conveyed as in the conventional case. There is no inconvenience that dust accumulates in the midway duct, and maintenance is easy. Since the dust collected for each type is collected for each type, the components of the collected dust can be guaranteed with certainty and can be reused, thereby improving the resource utilization efficiency. In addition, it is possible to easily respond to changes in the factory layout or increase in new pollution sources, and the piping that is the dust pumping means can be used in a small size, which simplifies the design in the factory and allows natural lighting. Can be fully incorporated, and the working environment becomes favorable.
