DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing floating dust in a factory for removing floating dust in the factory and purifying air.

[0002]

2. Description of the Related Art Dust in micron units floating in a factory such as a machine tool significantly impairs accuracy due to a product and has problems in hygiene such as health care of an operator. It is common that a method is adopted.

[0003]

In the conventional method of discharging floating dust using a duct, a large-scale factory requires a considerable number and volume of ducts, a large power load, and a removal of dust. Efficiency is not always good either.

[0004] The present invention is intended to efficiently remove micron-sized dust by using an existing crane garter installed in a factory without using ducts or the like, particularly in a large-scale factory.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a crane garter of a hoist installed in a factory is moved to adsorb and remove floating dust in the entire factory with a dust screen which is suspended from a reel provided on the crane garter. And a reel 4 in which a fine mesh dust-screen 3 is wound on a crane garter 2 which runs on rails 1 and 1 provided on both side walls near the ceiling in the factory. The supporting plate 5 is supported by a hydraulic cylinder 12, and a dust collecting tray 6, which also serves as a weight, is vertically provided at the lower edge of the dust removal screen 3, and a sensor for operating a reel winding motor 7 is provided at several places outside the dust collecting tray 6. 8 and a spray pipe 10 for spraying the disinfectant from the chemical solution tank 9 is disposed above the dust screen 3. The structure which is disposed a pair of rotary brushes 11, 11 driven by the coater was characterized.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dust screen 3 according to the present invention is wound around a reel 4 when a factory is in operation, and the support plate 5 is lifted up by a hydraulic cylinder 12 at the time of a break or the end of factory work. Reel 4 while holding near the ceiling
Then, the dust screen 3 is lowered. At this time, the dust removal screen is hung down to the vicinity of the floor by the aid of the gravity of the garbage collecting pan 6 which is also used as a weight while the disinfecting cleaning liquid is sprayed from the spray pipe 10. If the crane garter is moved in a self-propelled manner from the end of the factory in this state, the floating dust in the factory space is adsorbed and removed between the meshes of the dust collecting screen 3. In addition, water may be simply jetted from the spray tube, or static electricity may be applied to the dust removal screen. The flowing disinfectant is collected in the trash receptacle 6. In this way, the air in the factory is cleaned, the health of the workers is protected, and the accuracy of the products is ensured.

When the hanging dust collecting screen moves with the crane garter and encounters various machines in the factory, the sensor 8 detects it as an obstacle and drives the reel winding motor 7 to wind up the dust collecting screen 3 to remove the obstacle. Avoid and pass down again. Also, in the case of a machine tool that discharges a large amount of dust by special processing, a hanging dust screen is brought closer to use as a shielding curtain for dust removal to remove dust.

When the factory starts to operate, the rotating brush 11 is rotated while the dust collecting screen is being wound up, and the dust adhering to the screen is brushed off and collected in the ascending garbage collecting tray 6. When work in the factory begins, the dust screen is wound into a reel and space in the factory is secured.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a crane garter 2 which runs on rails 1, 1 provided on the upper side wall of a factory.
A support plate 5 on which a reel 4 around which a fine dust screen 3 made of, for example, a metal mesh is wound is supported by a hydraulic cylinder 12, and a dust collecting tray 6 serving as a weight is provided on the lower edge of the dust screen 3. A sensor 8 for operating a reel winding motor 7 is attached to the outer surface of the device, and a spray tube 10 for spraying a liquid from a chemical solution tank 9 is disposed above the reel 4 so as to sandwich the upper portion of the dust removal screen. And a pair of rotating brushes 11 and 11 driven by a motor are provided. Reference numeral 13 denotes a hoist.

[0010]

According to the present invention, the dust collecting screen is attached to a crane garter installed in the factory and the floating dust in the factory space is adsorbed by the reciprocating movement of the crane garter, so that a special expensive purification device is not required. This has the effect of easily and effectively removing micron-order dust in the interior, and has the effect of protecting the health of workers and ensuring the accuracy of the product.
