Description

Surface cleaning device of strip using high pressure water {APPARATUS FOR CLEANING THE SURFACE OF STRIP BY HIGH PRESSURE WATER}

The present invention relates to an apparatus for cleaning the surface of a strip after continuous annealing of a cold rolled steel sheet, and more specifically, using a high pressure water without using a conventional brush roll for cleaning the surface of the strip. By performing the surface cleaning operation of the strip while adjusting the spraying interval and the spraying width of high pressure water, it is possible to adjust the surface spraying interval of the high pressure water without changing the roll due to the small wear of the brush roll. The present invention relates to a surface cleaning apparatus for a strip using high pressure water.

In general, during the cold rolling process, after removing various foreign substances such as rolling oil and dust attached to the surface of the strip, the annealing operation is performed, and thus, the surface of the strip is cleaned. The cleaning operation is shown.

That is, as shown in Figure 1, when cleaning the surface of the strip using a scrub (SCRUBING) device 110, such a scrubbing device 110 is in contact with a brush roll (BRUSH ROLL) 120 that rotates at high speed While advancing the strip 100 in contact with each other, the surface of the strip 100 is sprayed with a nozzle 130 on the surface of the strip by rotating the brush roll 120 to perform a surface cleaning operation of the strip, wherein the brush roll 120 rotates in the direction opposite to the traveling direction of the strip (100).

However, in the surface cleaning operation of the strip 100 by the scrubbing device using the conventional brush roll 110 as described above, the brush roll 110 must be adjusted to friction at an appropriate force at all times on the surface of the strip 100. If not, that is, the brush roll 110 is less friction force, the cleaning efficiency of the strip 100 is reduced, on the contrary, if the friction force is large brush roll 110 is easily worn or broken to replace the brush roll 110 The bar and the maintenance and maintenance work of the scrubbing device is extremely difficult and the maintenance cost is increased by the replacement of the small brush roll (110).

In addition, it is necessary to adjust the position of the brush roll 110 as a screw jack (SREW JACK) 112 is installed by detecting the rotational resistance of the brush roll 110 to maintain the appropriate friction as described above, This is to increase the screw jack 112, if the rotational resistance is high, but to lower the screw jack 112, if the rotational resistance is low, due to such a complex device configuration, as well as manufacturing and installation work, the operation of the device is extremely It is difficult.

In addition, there are a number of problems in which an excessive number of workers are required for the maintenance of the device, and a safety accident such as a worker is squeezed into the facility during maintenance and maintenance work is high.

The present invention has been made to improve the above-mentioned various problems, and its purpose is to avoid frequent brush rolls for cleaning the surface of the strip, so that the frequent replacement and worn brush rolls due to the wear of the brush rolls can be avoided. The present invention provides a surface cleaning apparatus for a strip using high pressure water, which prevents surface damage of the strip in advance.

In addition, another object of the present invention is to perform the surface cleaning of the strip more effectively by performing the surface cleaning operation of the strip while adjusting the strip and the high-pressure water spraying interval and the spray width using high pressure water without using the brush roll. Thus, the post-processing of the strip is carried out precisely, and ultimately to provide an apparatus for cleaning the surface of the strip using high pressure water to improve the production productivity of the strip.

And, another object of the present invention, due to the simple structure to perform the surface cleaning of the strip by adjusting only the injection interval of the high pressure water, as well as the production and installation of the device, as well as the maintenance and maintenance of the strip using high pressure water It is to provide a surface cleaning device of.

The cover plate 29 to which the moving block 28 of the lower end is fastened to be narrowed or widened is installed to cover the first opening 22 when the motor is driven.

On the other hand, the high-pressure water injection pipe 50, the injection lip to variably spray the appropriate high-pressure water to match the high-pressure water for washing the surface (10 ') of the strip 10 to the width of the strip (10) ( LIP) 52 is installed in the vertical tank 20 in front of the support roll 30.

In addition, the high pressure water injection pipe 50 is integrally inserted through the second openings 22 'formed at both side walls of the vertical tank 20, and the high pressure water supply pipe 54 is connected through the vertical tank 20. Is connected to the center, the injection lip 52 is formed integrally toward the support roll 30 to one side of the outer peripheral surface of the injection pipe (50).

In addition, a piston 58 connected to the rod 56a of the cylinder 56 installed on the outer both sides of the vertical tank 20 is inserted into both sides of the injection pipe 50 to adjust the high-pressure water injection width when the cylinder is operated. It is made up of components.

Referring to the operation and effects of the present invention made in the above configuration in detail as follows.

As shown in Figures 2 to 4, after installing the vertical tank 20, which is a hollow steel plate structure inside the strip conveying line in which the strip 10 is transferred in the vertical direction, into the vertical tank 20 The reason why the vertical tank 20 is installed vertically is because the strip 10 is cleaned by using the high pressure water in the apparatus 1 of the present invention. This is to facilitate drainage.

On the other hand, the first and second openings 22, 22 'through which the support roll 30 and the high pressure water injection pipe 50 to be described later are formed at both sides of the vertical tank 20, respectively. The neck 30a portion of the support roll 30 positioned horizontally inside the vertical tank 20 passes through the first opening 22, and the neck 30a of the vertical tank 20 passes through the first opening 22. It is connected to the shaft 38a of the drive motor 38 installed through a support (not shown) on the outer side, and at the same time the neck 30a is fixed to the side wall of the vertical tank 20 integrally fixed plate 32 It is connected to the bearing block 36 mounted on the rod (34a) of the cylinder 34 horizontally installed in the).

Therefore, the support roll 30 smoothly conveys the strip 10 which is integrally rotated and conveyed during the operation of the driving motor 38, and at the same time, the support roll 30 moves forward and backward. 30 moves back and forth in the vertical tank 20 and pushes the strip 10 in close contact with the back of the strip 10 as will be described in detail below, eventually leading to the surface 10 'of the strip 10. And the spacing between the high-pressure water spraying lip 52 can be adjusted, which adjusts the pressure of the high-pressure water sprayed on the surface 10 'of the strip 10 to contaminate the strip 10, that is, dust or rolling oil. It is possible to adjust the high-pressure water injection force in accordance with the foreign matter attached state.

Next, as shown in Figures 2 to 4, through the second opening 22 'of the vertical tank 20, the high-pressure water supply pipe 54 connected to the center is inserted, the high pressure One side of the circumferential surface of the water pipe 50, that is, the horizontal direction toward the support roll 30 is formed so as to be integrally formed with an injection lip 52 capable of injecting high pressure water thereinto and injecting the high pressure water.

Therefore, the high pressure water supplied through the high pressure water supply pipe 54 is sprayed at a high pressure in a state in which the interval is adjusted as the support roll 30 through the high pressure water injection lip 52 to the surface of the strip 10. Foreign matter such as rolling oil or dust attached to the 10 'is effectively removed.

As a result, the surface 10 'of the strip 10 can be simply washed with high pressure water without the need for wear and parts replacement caused by using a conventional brush roll. In this case, the high pressure water pipe 50 Inside the both ends of the) is a piston 58, which acts as a cylinder 56 installed on a support (not shown) on the outer both sides of the vertical tank 20 to be sealed.

Accordingly, when the cylinder 56 is moved forward and backward, the interval between the piston 58 is narrowed or widened, so that the width of the high pressure water injected through the high pressure water injection lip 52 is adjusted.

At this time, as shown in Figure 4, the cylinder 56 is connected to the solenoid valve (S / V) controlled by the computer (P) connected to the central control unit is connected to the front, backward operation is controlled, the cylinder ( 56 is a double-acting cylinder, which is connected to a position sensor 56b on one side of the rod 56a, thereby controlling the operation of the cylinder 56. The width of the strip 10 is input to the computer P in advance. When the movement distance of the cylinder 56 is set automatically, eventually the injection width D of the high pressure water is adjusted.

On the other hand, as shown in Figure 2 and 4, the outer side of the support roll 30 in the inner side of the vertical tank 20 is installed to drive as a drive motor 24 on one side toward the outer front of the vertical tank 20. The cover plate 29 to which the movable block 28 of the lower end fastened to be narrowed or widened to the screw bar 26 is fastened.

Therefore, the cover plate 29 of the vertical tank 20 through which the support roll 30 passes by covering the support roll 30 side while adjusting the high-pressure water injection width D according to the operation of the drive motor 24. The high pressure water injected into the first opening 22 is prevented from leaking, and the motor 24 is also connected to the control valve 24a connected to the computer P to automatically adjust the width of the strip 10 set in advance. The interval is adjusted so as to match the high-pressure water jet width (D), wherein the cover plate 29 is provided with a high-pressure water blocking brush (29a) in the opened portion in consideration of the forward and backward movement of the support roll (30) It effectively blocks the external scattering of high pressure water.

Accordingly, the high pressure water spraying width D is adjusted according to the width of the strip 10 in the vertical tank 20 to be transported, and the high pressure water is sprayed on the strip surface 10 'so that the cleaning operation of the strip surface 10' is extremely efficient. It is made of.

As described above, according to the device for cleaning the surface of the strip using high pressure water, the surface of the strip due to frequent replacement and wear of the brush roll due to the wear of the brush roll is not used because a conventional brush roll is not used to clean the surface of the strip. There is an advantage in reducing costs by preventing damage in advance.

In addition, by performing the surface cleaning operation of the strip while adjusting the strip and the high-pressure water spraying interval and the spraying width using high pressure water without using the brush roll, the surface cleaning of the strip can be performed more effectively. It is carried out precisely, which in turn has the effect of improving the production productivity of the strip.

Finally, due to the simple structure of performing surface cleaning of the strip by adjusting only the spraying interval of the high pressure water, there is an excellent effect that is very easy to manufacture and install the device, as well as maintenance and maintenance work.
