The present invention relates to a filter tank of a swarf treatment facility for treating a swarf generated during a polishing operation by a strip grinder. In particular, the swarf is accumulated between the filters by removing the swarf floating in the polishing oil installed in the filter tank. The present invention relates to an apparatus for removing a floating swarf of a filter tank for preventing swarf.

In general, the coil subjected to annealing is subjected to a polishing line to remove defects on the surface of the strip, which is then sent to the next process, which is performed by strip grinders arranged along the line. The generated swarf is sent to the swarf processing facility through a chute installed at the bottom of the grinder.

The swarf generated during strip polishing is a mixture of coolant oil used for polishing and fine chips polished from the strip, and then aggregated together into a cotton form. The swarf sent to the swarf processing facility is transferred to oil and fine chips through screens and filters. Each can be separated and reused.

As shown in FIG. 1, the swap processing facility includes a swarf conveyor tank 101 for firstly filtering swarf discharged from the chute 100 and abrasive oil, and connected to the conveyor tank 101 for fine swarf. The filter tank 103 is provided with a filter 102 to separate the abrasive oil, and a clean tank 104 for storing the abrasive oil filtered from the filter tank 103.

Therefore, the swarf and coolant abrasive oil generated during the strip grinding are discharged to the swap conveyor tank 101 through the chute 100 and are first filtered while passing through the base screen (not shown) installed in the tank 101. Fine swarf and abrasive oil are sent to filter tank 103 where abrasive oil is separated through filter 102 where abrasive oil is sent to clean tank 104 and fine swarf is reprocessed through a bottom conveyor 105. Sent to the process.

The filter is composed of a case of a rectangular frame shape and a filter network overlying the case so as to achieve a predetermined width to filter the swarf from the oil and to suck out only the clean oil to the clean tank.

However, the above-described conventional structure has a problem that the swarf introduced with the oil into the filter tank does not fall to the bottom of the filter tank but floats on the oil and accumulates or accumulates gradually between the filters to be lowered and pushed down by the upper conveyor to damage the filter. There is this.

In addition, oil pumping failure occurs due to filter bag damage, and the line is stopped, resulting in oil contaminated by filtering defects entering the clean tank, which prevents the abrasive oil spray nozzles during the polishing operation. Will increase.

Accordingly, an object of the present invention is to provide an apparatus for removing a floating swarf of a swab filter facility filter tank, which is designed to solve the above-mentioned problems, and to prevent stacking of swap between filters.

It is another object of the present invention to provide an apparatus for removing a floating swarf of a filter tank for a swab treatment facility, which is capable of filtering a swarf suspended in oil to prevent an enlargement of the swarf.

On the other hand, the discharge portion for collecting the floating swarf filtered by the filter net 25 is installed in communication with the collecting duct 50 located above the filter tank 103, the outlet of the rear of the collecting duct 50 and An air inlet pipe 51 extending inside the filter tank 103 to generate a negative pressure in the collecting duct 50, and installed on one side of the air inlet pipe 51 to separate oil for separating the floating swarf ( 52), the discharge pipe 54 is connected to the side of the air inlet pipe 51 is dropped by the separation filter 52, the air is injected to the separation filter 52, the swap is separated from the separation filter 52 And an air injection pipe 53 for shaking off.

Hereinafter will be described the operation of the present invention.

When the advancing strip enters the polishing cabin, the rotating belt and the rotating strip contact with the inside of the polishing cabin, and the abrasive oil is sprayed to reduce the frictional heat generated during the contact and increase the polishing efficiency. By-product swarf from the grinding process are mixed together and introduced into the swarf tank along the oil chute and into the filter tank through the screen.

Therefore, the swarf entering the swarf tank along with the oil chute along with the abrasive oil is partially recovered from the swarf conveyor, and the unrecovered swarf is recovered by the inlet door filter conveyor through the screen along the abrasive oil into the filter tank. However, the floating swarf cannot be recovered by the filter conveyor because it is floating on the polishing oil due to the nature of the swarf.

At this time, the apparatus is operated to filter the floating swarf floating in the filter tank 103 and discharge the filter to the outside of the filter tank 103.

That is, when the swing motor 15 installed in the base frame 10 is operated, the swing shaft 11 is carried out through the pinion gear 16 installed on the drive shaft of the swing motor 15 and the rack 14 installed on the swing shaft 11. ) Is rotated to position the support shaft 20 above the filter tank 103.

Of course, since the filter unit is installed in the support shaft 20, the filter unit is also located on the filter tank 103.

Next, the elevating member 13 is lowered by the rack formed on the pinion gear 18 and the rack bar 17 according to the operation of the drive motor 19 installed on the rail member 12 and installed on the elevating member 13. The support shaft 20 is lowered toward the filter tank 103 so that the filter net 25 of the filter portion installed in the support shaft 20 is charged in the oil in the filter tank 103.

On the other hand, when operating the rotary motor 29 installed on the elevating member 13, the rotary cylinder 21 is engaged by the rack 30 to the pinion gear 31 installed on the shaft of the rotary motor 29. The support bracket 22 is rotated by the support shaft 20 to rotate the support bracket 22 installed on the rotary cylinder 21 about the support shaft 20.

As the support bracket 22 is rotated, the driven roll 24 installed at the outer edge of the support bracket 22 is placed in a deep or shallow position in the oil, so that the floating swarf can be efficiently rolled off.

As described above, when the position of the filter net 25 is set by the operation of each driving unit, the rotary motor 26 installed in the rotary cylinder 21 is operated to rotate the filter net 25.

That is, when the rotary motor 26 is operated, the drive roll 23 is driven through the sprocket wheel 27 and the chain 28 installed on the shaft of the drive roll 23 fitted to the rotary motor 26 shaft and the support shaft 20. Is rotated to rotate the filter net 25 spanning the driving roll 23, the driven roll 24, and the idle roll 32.

Accordingly, the floating swarf floating on the oil upper portion of the filter tank 103 is caught by the rotating filter net 25 and separated and moved to the rear side of the filter tank 103 along the filter net 25.

In this case, the air supplied to the air pipe 40 installed between the support brackets 22 through the air hose 41 is injected into the filter network 25 through the nozzle 42 of the air pipe 40. Swap caught in the net 22 is dropped to the rear of the filter tank 103.

On the other hand, the swap is sucked into the collecting duct 50 installed on the rear side of the filter tank 103, the rear side of the collecting duct 50 is in communication with one side of the air inlet pipe (51) The negative pressure is formed in the collecting duct 50 by the pressure of the air supplied to 51 so that the swap is sucked into the collecting duct 50 and sucked into the air inlet pipe 51.

The swarf sucked into the air inlet pipe 51 is caught by the separation filter 52 provided on the outlet side of the air inlet pipe 51 so that only the oil contained in the swap continues along the air inlet pipe 51 by air pressure. The swarf which is re-introduced into the filter tank 103 and caught by the separation filter 52 is guided to the discharge pipe 54 by the injection air of the air injection pipe 53 installed behind the separation filter 52 and discharged.

According to the floating swarf removal apparatus of the filter tank according to the present invention as described above, it is possible to smoothly remove the swarf, and to prevent damage to the filter by increasing the size of the swarf and to extend the service life. .

In addition, the secondary swab is introduced into the clean tank through the filter to obtain a secondary effect that can prevent the equipment accident to block the abrasive oil injection nozzle in the grinder.
