Description

Apparatus for drawing out the Fe-component in circular liquid}

The present invention relates to a device for extracting the iron component contained in the circulating alkaline solution collected in the pretreatment facility during the galvanizing process, more specifically, the iron core made of amorphous metal between the round permanent magnet The present invention relates to an iron component extraction device for a circulating solution that allows an iron solution to pass through an alkaline solution, attaches an iron component, and rotates and removes the attached iron component at high speed.

In general, as shown in FIG. 1, the galvanizing treatment equipment inserts the coiled steel sheet 9 into the payoff reel 8 in the entrance process and proceeds to the central process. After removing by the pretreatment facility 7, the steel plate which passed the furnace 1 facility is passed through the galvanizing tank 2 continuously.

Subsequently, the steel sheet is first cooled by passing the amount of zinc plating attached to the surface of the steel sheet by the air knife device 3 and then passing through the cooling device 4a installed on the upper portion thereof, and successively cooling the deflection roll 5a. The plating amount is measured by the plating amount measuring instrument 6 via the light, and then secondly cooled while passing through the cooling device 4b via another deflection roll 5b, and the cooled steel sheet passes through the deflection roll 5c. Proceeds to the next process.

On the other hand, the pretreatment facility 7 for removing the rolling oil on the surface of the steel sheet before the plating process, as shown in Fig. 2, the pump 15 in the alkaline solution tank 14 to the internal space equipped with a plurality of brush rolls 12 By supplying a solution by using, the alkaline oil remaining on the surface of the steel sheet by removing the rolling oil on the surface of the steel sheet passing between the brush roll 12, and spraying the washing water of the washing water tank 16 through the nozzle 13 After the removal, the washing water on the surface of the steel sheet is removed using the ringer roll 17 installed at the outlet side.

Here, the alkaline solution tank 14 and the wash water tank 15 supply the alkaline solution and the wash water through the pumps 15 and 18, and the alkaline solution and the wash water are circulated in the return solution. Inside the tank 14, the rolled oil removed from the steel sheet is precipitated.

Accordingly, since the rolling oil precipitated inside the tank 14 is not only pure rolling oil but also iron and oil components are mixed with each other, the alkaline solution is supplied to the brush roll 12 through the pump 15. A phenomenon of blocking the inside of the brush roll 12 may occur, and there is a high possibility that the pump 15 may fail due to a foreign substance such as iron, and the iron remains on the surface of the steel sheet. When entering into the furnace (1), the iron component remains on the surface of the steel sheet in a scale in the process of heat-treating the steel plate in the heating furnace (1), unplated on the surface of the steel sheet passed through the galvanizing bath (2) It caused the phenomenon or caused the scum to act as a factor to deteriorate the quality.

Therefore, the iron component contained in the alkaline solution to be reused provides a cause of a fatal defect in the steel sheet product, so that the workers work by replenishing the new solution while gradually flowing the solution inside the tank 14 to the pit side. By doing so, there is a problem of raising the manufacturing cost and causing workers to avoid work.

Therefore, the present invention has been devised in view of such a conventional problem, and its purpose is to install iron in the alkaline solution tank and continuously extract the iron component contained in the solution to prevent unplating of the steel sheet, and An object of the present invention is to provide an iron extracting device of a circulating solution that can extend the service life.

In addition, the second filter part 50 which sprays the solution toward the iron core to be magnetized and adsorbs and removes only the iron component contained therein is a circulation tube that circulates the solution in which the foreign matter is first removed in the filter accommodation pipe 34 ( 35 is provided with a cylindrical body 51 connected to the lower surface, the lower permanent magnet 52 is fixed to the bottom surface of the cylindrical body 51, the upper opening of the cylindrical body 51 Is closed by a cover 51a fastened by a plurality of bolt members.

In addition, an upper permanent magnet 53 is assembled to a drive shaft that penetrates the cover 51a and enters the cylindrical body 51 to the second motor 54 installed on the upper surface of the cover 51a. The same fastener 54a is connected to the circulation pipe 35 so as to be detachably connected to the central jet pipe 55 into which the solution is introduced. Here, the second motor 54 is provided with a direction change controller 54b for rotating the drive shaft alternately in the forward and reverse directions by a set angle.

In addition, the outer circumferential surface of the central ejection pipe 55 is injected in the radial direction A plurality of ejection openings 55a having a plurality of holes formed therein are formed in a pipe length direction, and an insertion hole 55c formed between the ejection openings 55a has an amorphous metal to easily have magnetic properties when passing through magnetic force. A plurality of cassettes 56 having iron cores 56a made of a material are mounted in the tube length direction so as to be replaceable.

The upper end of the central ejection pipe 55 forms a fitting jaw (55a) is assembled to the fitting hole (53a) of the upper permanent magnet 53, the lower end is fixed to the bottom surface of the cylindrical body (51) It is assembled to be rotatable in the central hole of the lower permanent magnet (52). Accordingly, the upper permanent magnet 53 is divided with the drive shaft which is reversed in the forward and reverse directions when the second motor 54 is operated with respect to the fixed lower permanent magnet 52.

Here, the upper and lower permanent magnets (52, 53) is composed of a disk-shaped magnet member in which the N pole, S pole is divided into equal intervals in the circumferential direction.

In addition, the central jet pipe (55) is provided with a circulating pipe (35) having a valve member (35a) and a washing water pipe (38) having a valve member (38a) communicating therewith, and an outer surface of the cylindrical body (51). It is equipped with a first discharge pipe 58 having a valve member (58a) to discharge the washing water desorbed iron components adsorbed to the iron core (56a) to the pit side, and the iron component solution is recycled to the tank (14) The second discharge pipe 59 having the valve member 59a is configured to be provided, while the cover 51a is provided with an air vent valve 20 to convert the pressure in the cylindrical body 51 to atmospheric pressure. .

The operation and effects of the present invention having the configuration as described above will be described.

The steel sheet released from the payoff reel 8 and drawn into the pretreatment facility 7 removes the rolled oil on the surface by the alkaline solution, and the alkaline solution from which the rolled oil and the iron component are removed is recycled into the tank 14.

When the suction pump 33 of the treatment pipe 31 installed in communication with the tank 14 is operated during the recycling of the alkaline solution, the filter receiving pipe of one branch pipe 31a having the valve member 37a which is opened is operated. Since the alkaline solution flows to the (34) side, foreign substances contained in the solution are firstly removed by the cylindrical filter 34a accommodated in the filter accommodation tube 34, and the solution from which the foreign substances are removed is the circulation tube 35. While being circulated and supplied to the first filter part 50 side, the pressure of the solution discharged through the circulation pipe 35 is often detected by the pressure gauge 36.

In this case, when the pressure of the solution is continuously measured through the pressure gauge 36, and the measured value is lower than the preset pressure value, this means that the amount of the filter is excessive in the cylindrical filter 34a in use, which causes clogging. Since it is indirectly informed, it closes the one valve member 37a which was opened, opens the other valve member 37b, switches the solution flow through the other branch pipe 31b, and the other filter receiving pipe attached to it. While the filtration operation is continued as the cylindrical filter 34a of (34), the cylindrical filter 34a, which has stopped the filtering operation, is taken out from the filter accommodating tube 34 and remounted after the internal cleaning.

Meanwhile, after the first filtering operation, the solution discharged through the circulation pipe 35 is supplied to the central ejection pipe 55 in the cylindrical body 51 and sprayed in the radial direction. In the panel, an electrical signal is transmitted to the direction change controller 54b to rotate the drive shaft of the second motor 54 by 45 °.

In this case, since the upper permanent magnet 53 integrally connected to the drive shaft is stopped after being rotated by 45 ° to one side with respect to the fixed lower permanent magnet 52, the N pole and the S pole are divided in the same circumferential direction. The upper and lower permanent magnets 52 and 53, which are each composed of disk magnet members disposed at an angle of 45 °, and face each other, have the same polarity N as shown in FIG. 6 (b) (d). 6 (a) and (c), different polarities (N, S, and S poles) are shown in the initial state in which the pushing force is applied to the pole and the N pole, the S pole, and the S pole. And N pole) to correspond to each other to act as a pulling force at this time, by the generated magnetic force will be able to magnetize the iron core (56a) disposed between the upper and lower permanent magnets (52, 53).

Accordingly, when the solution is supplied to the central ejection pipe 55 in the state where the iron core 56a is magnetized as described above, and the solution is sprayed in the radial direction through the ejection opening 55b of the outer peripheral surface, the iron contained in the solution The component is adsorbed and removed by the magnetized iron core 56a.

On the other hand, except for the valve member 35a of the circulation pipe 35, the valve member (38a) of the wash water pipe 38, each valve member (58a) (59a) of the first and second discharge pipes (58, 59) Since all) are closed, the solution from which the iron component has been removed flows back into the tank 14 through the bypass pipe 59b as the only passage.

In addition, the operation of dropping and removing the iron component attached to the iron core 56a in the cylindrical body 51 transmits an electric signal to the first motor 33a from the control panel to stop the operation of the circulation pump 33. The valve member 35a of the circulation pipe 35 is blocked, and the valve member 59a of the second discharge pipe 59 is opened to completely discharge the solution in the cylindrical body 51 to the tank 14 side. . At this time, since the pressure inside the cylindrical body 51 is increased, the internal pressure is removed by opening the air vent valve 57 mounted on the cover 51a.

At this time, the electric control signal is transmitted from the control panel to the direction switching controller 54b to return the upper and lower permanent magnets 52 and 53 corresponding to different polarities to the same polarity and to return to the initial state. By rotating the two motors 54 at high speed for 5 minutes, the central ejection pipe 55 having the iron core 56a which has lost its magnetism is rotated at high speed in one direction. Then, the valve member 59a of the second discharge pipe 59 that has been opened is shut off, and the valve member 38a of the washing water pipe 38 and the valve member 58a of the first discharge pipe 58 are opened.

In this case, the iron component rotated together with the central ejection pipe 55 at high speed, and the iron component adsorbed to the iron core 56a which lost its magnetic force is dropped from the iron core 56a, and the dropped iron component is the central ejection pipe 55. ) Is discharged to the pit side through the first discharge pipe (58a) with the washing water that is supplied instead of the solution and sprayed through the spout (55b).

According to the present invention having the above-described configuration, the iron cores disposed between the permanent magnets corresponding to each other are magnetized, and only the iron component in the solution is adsorbed as the magnetized iron cores. It can be removed by using iron solution, washing steel sheet, recycling alkaline solution, and recycling iron and iron in alkaline solution in pump, filter, brush roll and other equipments A practical effect is obtained which can prevent deterioration in quality.

While the subject innovation has been shown and described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit or scope of the subject innovation as provided by the following claims. I would like to clarify that knowledge is easy to know.
