BAG FILTER APPARATUS WITH MOVABLE DUST-ABSORBING HOOD}

The present invention relates to a filter dust collector, and more specifically, by installing the dust collection hood in accordance with the operating conditions of the installation site in the filter dust collector that collects and collects the dust (dust or powder) generated in the cold rolling mill of the steel mill, The present invention relates to a filter dust collecting device having a mobile dust collecting hood that can further improve work productivity and work efficiency.

In general, the steel plate 9 whose surface is solution-treated (plated or coated) in the steelworks plating process, as shown in Fig. 1 (a) and (b), upper and lower rollers (hereinafter referred to as roller members) (1a). (1b), the solid (solidified) component in the plating solution remaining in the steel sheet 9 is solidified by the contact reaction (oxidation reaction) with the ambient air when it proceeds in one direction while being in surface contact with the surface (1b). While being separated from the steel sheet 9, it is changed into a fine dust form and adheres to the roller members 1a and 1b to be fixed.

In this case, the dust formed as described above gradually increases the grain size by the frictional force between the roller members 1a and 1b and the steel sheet 9, causing a fatal defect on the surface of the steel sheet, thereby lowering the product value of the steel sheet product. There was a problem.

Therefore, in order to solve such a problem, a blade-type dust scraping device 8 is installed to be in contact with the surface of the one side roller member 1b so as to remove foreign substances attached to the surface of the roller. The dust adhering to the surface of the roller member 1b rotating in the direction is scraped off.

Then, the dust scraped off by the dust scraping device (8) is sucked into the dust collection hood (2) connected to the suction pipe (5), the transfer device (8a) for moving the dust scraping device (8) if necessary and the A bracket 8b for supporting the devices 8, 8a is mounted separately.

In addition, Figure 2 is a schematic configuration diagram showing a general filter dust collecting device, as shown in the upper portion of the roller member (1b) that is the source of dust generating dust removed by the dust scraping device 8 as described above A dust collecting hood (2) which sucks in with the surrounding air, a suction pipe (5) which is a passage for forcibly transporting the sucked dust, and a dust collecting device to filter the dust and drop it to the lower hopper, and discharge only the clean air caught to the outside. (6), a blower (7a) as a power source for forcibly suctioning dust and exhausting the filtered air to the outside (atmosphere) as the dust collecting hood (2), and a discharge pipe (7) which is a passage through which the filtered air is discharged to the outside (atmosphere) Of course, the control panel for operating and controlling the whole bag filter is installed separately.

On the other hand, the dust collection hood (2) that primarily sucks in the dust forcibly removed by the dust scraping device (8) is made of steel or synthetic resin, the inlet shape is rectangular or oval, the suction pipe is usually an upper structure It is fixedly connected to (5).

Here, in the conventional case in which the dust collecting hood 2 is fixedly installed, it is possible to give a sense of stability in the installation structure, while the dust collecting hood 2 is removed at a work place where product inspection or facility inspection is performed during continuous operation under facility operation conditions. There is a problem that it is difficult to fixally install the upper portion of the roll member 1b.

In addition, when the width of the roller member (1b) is significantly greater than the inlet width of the dust collection hood 2, the dust generating source is formed in a wide width range, all of the dust forcibly removed as a dust collecting hood 2 is fixedly installed It is difficult to inhale smoothly, and if the inlet width of the dust collection hood 2 is formed to solve the problem, the occupied space of the dust collection hood 2 becomes relatively large in a limited installation space, causing interference with other equipment. Of course, there was a problem that the entire equipment scale unnecessarily large.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the purpose of which is to equip the form of the dust collection hood to move freely to minimize the space occupied by the dust collection hood in the limited installation space and the existing equipment The present invention aims to provide a filter dust collecting device having a mobile dust collecting hood that can eliminate interference in space and greatly reduce the operator's operating load due to automation.
