The present invention relates to an apparatus for removing foreign substances in a degreasing vessel that can be easily separated and removed from foreign substances such as iron and brush chips generated during strip grinding in a stainless steel cold rolling mill of a steel mill.

In general, the grinding line of the stainless cold rolling mill performs grinding operation to remove surface defects generated on the surface of the strip, and in order to prevent frictional heat and degradation of polishing efficiency generated when the strip and the polishing belt are in contact with each other, grinding is performed. Oil is injected.

However, when the abrasive oil remains on the strip surface, the demand is impossible to weld during the reprocessing of the strip, so that the abrasive oil remaining on the strip surface is removed through a degreasing facility before shipment of the product.

Conventionally, for this purpose, as shown in FIG. 1, the strip 2 subjected to the polishing cabin 1 in the stainless cold rolling mill is supplied from the degreasing cleaner tank 5 while passing through the squeeze roll 3 and the rinse tank 4. After being washed (degreased) by the alkaline solution and then transferred to a subsequent process, the washing solution is collected by the degreasing cleaner tank 5 and then pumped by the pump 6 to be reused.

In this degreasing process, when the strip 2 passes through the rinse tank 4, fine foreign substances such as swarf iron or brush chips are generated, and the foreign substances generated are recovered together with the cleaning liquid to the degreasing cleaner tank 5. As a result of the water collection, the disadvantage is that the washing solution cannot be reused continuously.

In addition, for continuous use, since the foreign matter mixed in the cleaning liquid must be used after separating and removing, the work is cumbersome and excessive work time is also caused.

In addition, since stainless must maintain a high quality, in particular, since product defects are caused by fine foreign substances, the cleaning solution must be replaced or checked at any time, so that the consumption of the cleaning solution is increased and the management is difficult, and thus productivity is significantly reduced.

The present invention has been made in view of the above-mentioned problems of the prior art, and has been created to solve this problem, and it is possible to quickly and easily automatically remove foreign substances generated in the degreasing process of the stainless strip, thereby improving product quality and productivity. It is an object of the present invention to provide a debris removal device of a degreasing container that can reduce costs through continuous recycling of cleaning liquids and reduce work load due to maintenance.

The above object of the present invention is a rectangular box-shaped housing fixed to the upper surface of the degreasing cleaner tank; A downwardly inclined guide box having a sump fixed to one side of the housing and having a discharge pipe connected thereto; Winding reels and winding reels, respectively fixed to upper ends of the longitudinal sides of the housing and having at least one driving means; A filter disposed on the winding reel and the winding reel; A plurality of idle rolls properly disposed adjacent the bottom surface of the housing to tension the filter; Guide vessels fixed to both sides of the housing so as to be positioned on an adjacent upper surface of the take-up reel filter; It is achieved by providing a debris removal device of the degreasing vessel characterized in that it comprises a suction pipe connected to the guide tank to supply the degreasing solution of the degreasing cleaner tank by the suction pump.
