The present invention relates to an apparatus used for manufacturing electrical steel sheet, and more particularly, to an apparatus for removing a deposit adhered to an inner wall of a tank for storing MgO (magnesium oxide) solution plated on the surface of electrical steel sheet.

In general, electrical steel is a material used in the application of electrical and electronic devices, and divided into oriented electrical steel and non-oriented electrical steel according to the direction of magnetic anisotropy. After cold rolling, decarbon annealing is applied and MgO, an annealing separator, is applied. Annealing is performed.

The application of annealing separator in the manufacture of electrical steel sheet prevents fusion between coils during high temperature annealing by applying MgO suspension to the surface of the material after decarbonization annealing, and reacts with oxides (mainly FeO, SiO2) on the surface of the material to provide excellent insulation. This is to form a glass film.

As annealing separator used here, MgO is usually used, and MgO is produced by calcining ore such as dolomite, or washing and drying after precipitation of Mg ions in seawater with alkali hydroxides such as Ca (OH) 2. It is prepared by crushing and firing.

MgO, which is usually used for electrical steel, is manufactured from seawater, and unlike high-density and inert refractory materials (commonly called magnesia), which occupy most of the demand, low-density, active MgO is used, which reacts with the oxide layer on the surface of the material during high temperature annealing. This is because the formation of a refractory layer of forsterite (2MgO, SiO2) is required.

The aqueous solution of MgO is sent to a separate coating ringer roll while stirring at regular intervals in the tank to be coated on a steel sheet. Since the nature of the MgO aqueous solution is easy to attach to the iron plate it is easily attached to the inner wall of the tank.

In particular, as the level of the MgO aqueous solution filled in the tank gradually decreases, the residual aqueous solution on the wall is easily solidified by contact with air, mixed in the solution, and shows a coating-like thick film during coating. There is a serious problem in that it causes oxidative surface defects by tissue exposure during post-processing by causing convex flaw and film defects during winding.

Therefore, in order to solve such a problem, the aqueous solution is periodically discharged inside the tank to remove the fixed matter, and as such work is frequently generated during the work, it causes trouble and excessive aqueous waste in the work, thereby increasing the amount of raw materials. Problems remain all the time, causing cleaner fish coating defects on workers and causing even more problems.

Therefore, the present invention has been proposed to solve the problems of the prior art, by performing the stirring in the forward and reverse direction alternately during the stirring operation to remove the deposits fixed on the inner wall of the tank to improve the coating quality and the number of cleanings generated during the operation It is to provide a device for removing the deposit on the inner wall of the tank that can prevent the unit rise by increasing the productivity through the reduction and the loss of the aqueous solution.

The fixed object removal device of the present invention for achieving the above object is a drive motor which is installed on the top of the tank in which the magnesium oxide aqueous solution is stored to generate a driving force, a stirring blade fixed to the lower rotating shaft of the drive motor, the drive A driver configured as a reducer connected to the upper rotation shaft of the motor; A rotating body which is rotatably seated on an upper portion of the tank and the driving motor is located at the center thereof, and a plurality of rolling rollers are installed on an outer circumferential surface of the tank; A rotating part fixed to the upper side of the tank and configured as a forward rotation means for rotating the rotation body in a forward direction; And a rotary guide rod fixed to the rotary shaft of the reducer, a touch bar fixed to the side of the rotating body, a slide rod elastically coupled to the rotary guide rod, and pushing the touch bar or contacting the forward rotation means. It is fixed to the side includes a switching unit consisting of a curved guide for guiding the movement of the slide bar.

On one outer circumferential surface of the rotating body 11, a plurality of rolling rollers 13 are installed to correspond to the forward rotation means.

A support rod 15 positioned inside the tank 1 is installed at the lower portion of the rotating body 11, and a support roller 17 clouded from the bottom of the tank 1 at the lower end of the support rod 15. Is installed, the brush 19 is installed on the side of the support rod 15 to brush the inner wall of the tank (1) during the rotation of the rotating body (11).

And the forward rotation means is installed on one side outer circumferential surface of the tank 1, a plurality of "L" shaped fixing bar 21 is fixed to the outer circumferential surface of the tank 1, and rotates on the upper end of the fixing bar 21 A plurality of connection links 23 fixed to each other, a touch roll 25 and a return roll 27 respectively rotatably installed at both ends of the connection link 23, and a separation prevention jaw fixed to the fixing bar 21. One side is fixed to (29) and the other side is composed of a return spring 31 is fixed to the connection link (23).

The forward rotation means rotates about the fixed bar 21 when the touch roll 25 is pushed by the switching unit to be described later, and the return roll 27 pushes the rolling roller 13 during the rotation to rotate the rotating body ( 11) is rotated in the forward direction.

The switching unit is a rotary guide rod 33 fixed to the rotary shaft of the reducer 7, a slide rod 35 coupled to the rotary guide rod 33, and the rotary body 11 is fixed to the rotary body 11 It consists of a touch bar (37) for forward and reverse rotation only at half of the, a curved guide (39) fixed to the side of the rotating body (11), and a fixed guide (41) fixed to the outer surface of the drive motor (3).

Here, the rotation guide rod 33 is formed with an inlet groove 33a introduced inward from the end, and the inlet groove 33a is inserted with a slide bar 35 having an approximately "a" shape, and the inserted slide rod. In order to prevent the 35 from falling out, a stopper is formed at the inlet of the inlet groove 33a and a flange is formed at the end of the slide bar 35.

A tension spring 44 is disposed between the slide rod 35 and the rotation guide rod 33 to return to the original position when the force for removing the slide rod 35 from the inlet groove 33a is released.

The vertical portion of the slide bar 35 is rotatable vertical rotation roll 43 is installed.

When the slide bar 35 is rotated together with the rotation guide bar 33 and is caught on the vertical rotation roll 43, the touch bar 37 to be rotated together is fixed to the upper end of the rotating body 11.

And the curved guide 39 is fixed to the outer circumference of the rotating body 11, the vertical rotary roll 43 is rotated in the reverse direction proceeds along the curved guide surface, the tension spring is tensioned.

Fixture removal apparatus according to the present invention configured as described above has the following actions.

First, when the driving motor (3) supplied with power is rotated, the stirring blade rotates in the reverse direction, and at the same time, the rotation speed of the driving motor (3) is reduced by the reducer, and the rotary guide rod (33) is lower than the stirring blade. It will rotate at a slower speed.

As soon as the rotation guide rod 33 starts to rotate, the touch bar 37 is in contact with the vertical rotation roll 43, and the vertical rotation roll 43 continues to rotate while pushing the touch bar 37. As a result, the rotating body 11 also rotates together, and as a result, the brush 19 rotates in the reverse direction, thereby removing the fixed matter fixed to the inner wall of the tank.

Removal of this fixation is stopped while the vertical rotary roll 43 passes the curved guide surface. That is, when the vertical rotation roll 43 proceeds along the curved guide surface, the tension spring increases and the slide rod 35 extends from the inlet groove 33a to push the touch bar 37 to the vertical rotation roll 43. This touch bar 37 is moved away from it.

Subsequently, the vertical rotary roll 43 moving along the curved guide surface pushes the first touch roll 25 while leaving the curved guide 39, and the connecting link centers the fixing bar 21 by the pushing force. It rotates to, and the return roll 27 is pushing the rolling roller 13 in the forward direction by the rotation.                     

As a result, the rotating body 11 moves as the return roll 27 pushes in the forward direction, and the vertical rotating roll 43 continuously rotating pushes the second touch roll 25 to rotate the rotating body 11 through the above-described process. ) Will move in reverse.

At this time, the rotating link link 23 is returned to its original state by the return spring (31).

And while the rotor 11 rotates little by little in the forward direction, the brush 19 also removes the deposits on the inner wall of the tank.

In this way, the vertical rotation roll 43 to make the operation is beyond the guide roll 45 fixed to the fixed guide 41, the touch bar 37 in the original position due to the forward rotation of the rotary body 11 again Push to allow the rotating body 11 to rotate in the reverse direction.

As described above, according to the apparatus for removing a deposit of the present invention, while stirring the aqueous solution of MgO, the brush is rotated in a forward and reverse direction inside the tank to remove the deposits fixed on the inner wall of the tank, thereby coating the electrical steel plate later. The coating quality of the MgO aqueous solution can be improved, and the number of cleanings generated during the operation can be reduced, thereby increasing the productivity and reducing the loss of the aqueous solution.
