Referring to the operation of the present invention made in the above configuration in more detail as follows.

As shown in Figures 2 to 5, when the steel sheet manufactured in the steel mill is performed to perform a plating operation in order to make the surface of the steel sheet or the surface condition according to the user's request, or the use of the steel sheet, approximately in the plating cell 10 The hazardous vapor (V) generated in the plating solution 16 stored at 65-70 ℃ is more effectively collected and removed, and in particular, the harmful vapor condensed by extruding it in the state where the harmful vapor (V) is absorbed as the absorbing member (86). The steam (V) is re-injected into the plating cell 10, and the uncondensed harmful vapor (V) is sent to an external purifier to effectively prevent equipment damage and worker safety accidents caused by harmful vapor (V). The harmful vapor dust collector 1 of the steel plate plating cell of the present invention is as follows.

First, as shown in FIGS. 2 and 5, the dust collecting apparatus 1 of the present invention is always harmful during the plating operation of the steel sheet S using the driving force of the conductor roll 12 installed in the plating cell 10. The steam dust collecting operation is performed, and if there is no plating work or the internal inspection of the plating cell 10 is performed, it is installed in a folding type so as to fold the base 24 having two stages.

On the other hand, in the state where the base 24 is horizontally deployed on the plating cell 10 during the plating operation, when the roll shaft 72 of the conductor roll 12 rotates, the main gear 74a of the gear portion 74 is rotated. The main gear pulley 74c installed at one side of the upper portion of the hood 54 and the connecting gear 74b engaged therewith rotates integrally.

Therefore, the drive belt 76b fastened to the main gear pulley 74c rotates, and as a result, a plurality of gear pulleys 76c mounted on the support block 76b to the upper side of the hood 54 are integrally fastened. It rotates as the driven belt 76b.

On the other hand, the rotary shaft 78 fixed to the lower side of the gear pulley 76c is moved through the hood and the fixing plate (82a) (82b) and the absorbing member (86) located inward through the next (54) The inner dust collecting fan 56 of the duct member 52 seated in the opening 22a of the main base 22 will be rotated integrally, and eventually the dust collecting fan 56 will be rotated by the rotational force of the conductor roll 12. Let's go.

At this time, the main base 22 is horizontally fixed to both sides of the conductor roll 12 over the upper end (10a) of the plating cell 10, a plurality of duct members 52 in the opening (22a) formed on both sides ) Is seated, and the dust collecting fan 56 is located inside thereof, and the harmful vapor V is collected more smoothly through the opening 22a.

It is discharged through the main duct 90 connected through the hood 54.

Next, as described above, the shaft 42a rotatably connected via a bearing or the like between the supports 22b installed on the main base 22 is mounted to a bracket 24b vertically installed on the base 24.

Therefore, when the cylinder 44a installed on the main base 22 is raised, the rack gear plate 44 connected to the rod of the cylinder 44a rotates the pinion gear 42 mounted on the shaft 42a, and eventually With the shaft 42a as the axis, the bases 24 may overlap each other or may be deployed if necessary.

Next, when the dust collecting fan 56 is operated to introduce harmful vapor V into the hood 54 through the openings 22a and 24a of the main base 22 and the base 24, as described above, the main duct Is processed outside through the 90, the absorbing member, that is, the sponge 86 is fixed to the inside of the hood 54, the upper and lower side of the absorbing member 86 to rotate the dust collecting fan 56 The rotating shaft 78 is inserted, the moving plate 82a is located above, and the fixing plate 82b is fixed on the duct member 52 below.

While the hood outer ring 88b of the support shaft 88a horizontally fixed to the 82a descends, the movable plate 82a descends about the rotation shaft 78 while the lower absorbing member, that is, the sponge 86 and the like. Extrude.

As a result, as shown in Figure 4, the dust collecting fan 56 is rotated through the duct member 52, the harmful vapor (V) introduced into the dust collector 1 of the present invention is primarily in the absorbing member (86). Absorbed by, but not absorbed harmful vapor (V) is secondarily discharged through the main duct 90, when the moving plate (82a) is lowered harmful vapor absorbed by the absorbing member 86, such as the sponge ( V) drops harmful vapor V condensed by being extruded between the fixed plate 82b and the moving plate 82a into the plating cell 10 again.

Accordingly, according to the harmful vapor dust collecting apparatus 1 of the steel plated cell of the present invention, compared with the conventional simple dust collecting duct, the harmful vapor can be collected more reliably, and if necessary, it can be folded in two stages, which is convenient. Further, the condensed extruded harmful vapor (V) to be put again in the plating cell 10 is more practical.

As described above, according to the harmful vapor collecting device of the steel plated cell of the present invention, by collecting the harmful vapor of the plating cell through a plurality of hood means, adjacent to the plating liquid level of the plating cell as much as possible, after fully collecting the epidemic vapor, By putting it in the plating cell, there is an advantage to prevent the damage of the peripheral equipment and the harmful environment of the worker by the epidemic steam.

Furthermore, by placing the dust collector under the exposed transfer line of the steel plate and the conductor roll, and developing or folding it if necessary, it prevents the generation of precipitates that fall while forming harmful vapors in the dust collector, thereby causing the steel sheet by the precipitate. It is to provide an excellent effect of further improving the quality of the steel sheet by preventing the surface damage of the film in advance.
