A general dust collector is a device for filtering various suspended dusts or harmful substances generated in the working process, and is essential for industrial sites that generate a large amount of dust such as dust.

It is an essential device at the site where harmful substances occur, such as many factories such as clothing, yarn, cotton spinning, milling, loess products, grinding and cement, or where many dusts, odors and smoke are floating in the air, such as steel mills. .

As such, dust generated at industrial sites not only pollutes the environment, but is also harmful to human health when exposed to humans such as eyes, mouth, nose, skin, etc. of workers or people around them. There is a risk of exposure.

Accordingly, an industrial dust collector is installed to collect and process dust generated during work. For example, a facility that emits smoke, such as a factory chimney, is equipped with a device for collecting dust contained in the smoke.

In addition, there is a utility model registration No. 0310133 "single worktable combined dust collector capable of adjusting the work space" as a prior art for collecting dust generated during work such as grinding and welding. This will be described with reference to FIGS. 1 and 2.

1 is a perspective view of a dust collecting device according to the prior art, Figure 2 is a side view. Referring to the drawings, the prior art is that the overall shape is rectangular, the wheel (R) is formed so as to be easy to move near the bottom edge, the blocking plate 10 is formed on both sides of the blocking plate ( The bottom of the front end 10 is provided with a fastening portion 100, the rear end is formed with a hinge 101 on both sides and the bottom surface is composed of a suction port 11 perforated with a myriad of suction holes (110) (1) And, the lower portion of the suction port 11 of the work table 1 is formed with a space portion 20, the rear end of the space portion 20 is provided with a passage 21 and the passage 21 is directed downward It consists of the duct 2 formed long.

However, the prior art as described above is difficult to perform a variety of operations because the area of the work table (1) for processing the dust is generated. In addition, since only the front and side surfaces of the workbench 1 are blocked by the blocking plate 10, dust generated during work may spread to the periphery of the workbench 1 through the flow of air, thereby preventing dust generated during work. There is a problem that cannot be captured completely.

That is, since the dust collector of the prior art has a structure that sucks dust into the lower part of the work table 1 and processes it, some of the dust generated during work such as polishing may be sucked into the lower part of the work table to collect, but generate strong wind speed. In the case of painting and grinding work, it is reflected and raised from the dust block of the workbench according to the atmospheric conditions of the work site and spreads widely.
