Description

Floating sludge removal device of degreasing container {DEVICE FOR REMOVING FLOATING SLUDGE OF GREASE-REMOVED CONTAINER}

The present invention relates to an apparatus for removing suspended sludge of a degreasing vessel, which is capable of easily separating and removing suspended sludge, such as iron and brush chips, generated during grinding of a strip 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. When the water is collected and suspended and settled and then resupplyed in this state, these foreign substances close the spray nozzles, causing degreasing efficiency as well as degreasing failure.

The present invention has been made in view of the above-described problems of the prior art as described above, and created by solving the foreign matter generated in the degreasing and polishing process of the stainless strip by collecting the suspended by floating it in the state of the product quality and productivity It is an object of the present invention to provide an apparatus for removing suspended sludge in a degreasing container that can be improved.

The driven pulley 124 is preferably disposed to be completely immersed in the degreasing solution contained in the degreasing cleaner tank (5).

The drive pulley 122 is rotatably installed in the inner side adjacent to the upper end of the housing 110 in parallel with the driven pulley 124, and the driving means 120 such as a motor is formed at one side of the shaft of the drive pulley 122. Is connected.

The driving means 120 is fixed to the outer side of one side of the housing 110.

A belt 130 is wound around the driving pulley 122 and the driven pulley 124, and a plurality of buckets 132 are fixedly installed at an interval on the outer surface of the belt 130.

As shown in FIG. 4, the belt 130 attaches a rubber plate 142 having a predetermined thickness to one side of the stainless steel plate 140, and a plurality of magnet bars between the rubber plate 142 and the stainless steel plate 140. 144 is constituted by excretion.

The magnet bar 144 is installed in a plurality at regular intervals along the longitudinal direction of the stainless steel plate (140).

The bucket 132 is fixed to the outer surface of the rubber plate 142, the bucket 132 is bolted to the belt 130 by a plurality of support brackets 134 for supporting it in the longitudinal direction.

In particular, it is preferable that the bucket 132 is formed of a filter cloth so that foreign substances are filtered out and the degreasing solution can pass therethrough.

Barrier wall 200 is formed on one side of the upper end of the housing 110, the partition wall 200 is extended upward from the central portion of one side of the housing 110 is disposed to be inclined to the upper adjacent position of the outer peripheral surface of the driven pulley 122 And it is installed to be positioned at a minute interval with the rotation driven bucket 132.

The outer space of the housing 110 partitioned by the partition wall 200 is sealed to form a foreign material collection tank 210.

The first driving motor 220 is fixed to one side of the foreign material collection tank 210, and the first screw shaft 222 is connected to the rotation shaft of the first driving motor 220.

A plurality of screws are formed at a portion of the first screw shaft 222 positioned inside the foreign matter collection tank 210.

In addition, a discharge pipe 212 is formed through the rear surface of the foreign matter collection tank 210, a movable foreign matter collection box 230 is disposed directly below the discharge pipe 212.

A second driving motor 340 is fixed to one end surface of the iron fraction collection tank 300, and a second screw shaft 342 is fixed to a rotation shaft of the second driving motor 340.

A plurality of screws are formed in a portion of the second screw shaft 342 located inside the iron collection tank 300.

Directly above the iron collection tank 300, an iron removal plate 260 which is in contact with and adjacent to an inner surface of the stainless steel plate 140 constituting the belt 130 is installed.

Both ends of the iron removing plate 260 are fixed to both sides of the housing 110.

On the other hand, the injection nozzle 400 that can be sprayed in the rotational direction is disposed on the upper side adjacent to the drive pulley 122, the injection nozzle 400 injects a high-pressure air to the bucket 132 bucket 132 It is an additional means provided to smoothly drop the foreign matter remaining in the foreign matter collection tank 210 side.

The present invention made up of such a configuration works as follows.

The degreasing solution L supplied from the degreasing cleaner tank 5 by the pump 6 is evenly sprayed on the upper and lower end faces of the strip 2 which proceeds through the plurality of nozzles 8 to adhere the abrasive oil adhered to the surface thereof. This will clean up any foreign objects you have included.

Fine particles of foreign matter (such as brush chips), including iron removed together, are recovered in the degreasing cleaner tank 5 through the drain line D together with the degreasing solution L.

Even if the suspended matter is induced or settled, the degreasing solution L is flowed by the driving and driven pulleys 122 and 124 and the bucket 132 driven by the driving means 120, and some of the foreign matter is naturally It is introduced into the bucket 132.

The introduced foreign material is moved upward by riding up the bucket 132 and then falls at the instant of the direction change while passing through the outer circumferential surface of the driving pulley 122, and the bucket 132 is continuously rotated downward.

At this time, the air injected at high pressure through the injection nozzle 400 is assisted so that even foreign matters remaining in the bucket 132 can be easily dropped.

The fallen foreign material flows down the upper surface of the partition wall 200 and is collected into the foreign matter collecting tank 210, and moved to the discharge pipe 212 side by the first screw shaft 222 that is rotated to the foreign matter collecting container 230. Collected and disposed of.

On the other hand, the iron powder in the foreign material is rotated while being adsorbed to the inner surface of the belt 130, that is, the stainless steel plate 140 by the magnetic force of the magnetic bar 144 is removed by the iron removal plate 260 after collecting iron powder It is gathered into the tank (300).

As described above, the collected iron is moved to the discharge pipe 310 side by the second screw shaft 342 that is rotated to be collected in the iron collection box 320 to be disposed of.

This process is able to automatically separate and remove the foreign matter and iron contained in the degreasing solution (L) by continuously circulating repeatedly.

As described in detail above, the present invention provides the following effects.

First, continuous recycling is possible by quickly and easily separating and removing foreign matter contained in the degreasing solution.

Second, there is an advantage to further improve the quality of the product by removing the foreign matter contained in the degreasing solution as much as possible.

Third, it is easy to manage and maintain, the consumption of degreasing solution can be reduced, thereby reducing the production cost.
