Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a sinking roller device. Background Art

[0002] At present, a variety of liquids are used in the production of steel strips, such as water, acid, alkali, passivation liquid and various electroplating liquids. In order to guide the strip 1 to pass through the tank 2 containing these liquids 3, it is necessary to set a sinking roller 4 at the bottom of the tank 2, that is, a roller whose roller body is completely immersed in the liquid. The strip enters the liquid 3, bypasses the sinking roller 4, and then passes through the liquid 3 or enters the next process. With the advancement and maturity of production technology, the process speed is getting higher and higher. The strip 1 running at a high speed in the tank 2 will drive the liquid on the surface of the strip to flow in the same direction, and the sinking roller 4 rotating at a high speed at the bottom of the tank 2 will also drive the liquid on its surface to flow, which makes the flow of the liquid in the tank very complicated and has a great impact on the stable operation of the strip.

[0003] Figure 1 It is a schematic cross-sectional view of a tank body, wherein the sinking roller 4 in the tank body 2 rotates clockwise, and the strip 1 enters the tank body 2 downward from the right side of the sinking roller 4, bypasses the sinking roller 4, and exits the tank body 2 upward from the left side of the sinking roller. The strip entering the tank body 2 from the right side of the sinking roller 4 is called the inlet strip segment 101, and the strip exiting the tank body 2 from the left side of the sinking roller 4 is called the outlet strip segment 102; the liquid on the left and right surfaces of the inlet strip segment 101 flows downward with the strip, and the liquid at the sinking roller 4 below the left side of the inlet strip segment 101 rotates clockwise with the sinking roller, and the two are in the inlet strip segment 101. 01 merges with the area just before the contact with the sinking roller 4, forming a positive pressure, which is greater than the pressure on the right side of the inlet strip section 101, pushing the inlet strip section 101 to tilt to the right; the liquid on the left and right surfaces of the outlet strip section 102 flows upward with the strip, and the liquid at the sinking roller 4 below the right side of the outlet strip section 102 will divert part of the liquid as the sinking roller 4 rotates, forming a negative pressure, which is less than the pressure on the left side of the outlet strip section 102, causing the outlet strip section 102 to tilt to the right. This effect will become more and more obvious as the running speed of the strip and the speed of the sinking roller increase. Some other devices are often set in the tank body 2, such as plates for electrolysis and electroplating. In order to improve efficiency, these devices are close to the strip. At this time, if the strip 1 is tilted too much, it will be unequally spaced from these devices on both sides of the strip 1, affecting the process effects on both sides of the strip 1. If the strip 1 is tilted too much, it may even rub against these devices, causing serious consequences. Therefore, it is necessary to make improvements to solve the above problems.

[0021] like Figure 2The utility model embodiment provides a sinking roller device, including a sinking roller 4 and a tank body 2 for containing liquid 3, wherein the sinking roller 4 is arranged in the tank body 2, the sinking roller 4 is immersed in the liquid 3, a strip 1 is wound around the sinking roller 4, and the strip 1 is U-shaped in the tank body 2, the strip 1 includes an inlet strip section 101 that moves vertically downward to approach the sinking roller 4, and an outlet strip section 102 that moves vertically upward to leave the sinking roller 4, and between the inlet strip section 101 and the outlet strip section 102 is a strip section that is wound around the sinking roller 4 and moves in contact with the sinking roller 4, and a first rectifying plate 501, a second rectifying plate 502, a third rectifying plate 503, and a fourth rectifying plate 504 are arranged in the tank body 2, and the first rectifying plate 501, the second rectifying plate 502, the third rectifying plate 503, and the fourth rectifying plate 504 are all horizontally arranged. The first rectifying plate 501, the second rectifying plate 502, the third rectifying plate 503 and the fourth rectifying plate 504 are all located above the sinking roller 4, the first rectifying plate 501 is arranged on the side where the inlet strip segment 101 is not in contact with the sinking roller 4, the second rectifying plate 502 is arranged on the side where the inlet strip segment 101 is in contact with the sinking roller 4, the third rectifying plate 503 is arranged on the side where the outlet strip segment 102 is in contact with the sinking roller 4, and the fourth rectifying plate 504 is arranged on the side where the outlet strip segment 102 is not in contact with the sinking roller 4. The distance between the first rectifying plate 501 and the inlet strip segment 101 is farther than the distance between the second rectifying plate 502 and the inlet strip segment 101, and the distance between the fourth rectifying plate 504 and the outlet strip segment 102 is farther than the distance between the third rectifying plate 503 and the outlet strip segment 102. The rectifying plate of the sinking roller provided by the utility model can effectively improve the inclination problem of the inlet strip section 101 and the outlet strip section 102 before and after the sinking roller caused by the flow of liquid in the tank. Reasonable adjustment of the distance between the rectifying plate 5 and the strip 1 can effectively adjust the running trajectory of the strip 1 bypassing the sinking roller 4 at various speeds, avoiding interference between the strip 1 and the equipment in the tank body 2.

[0022] In this embodiment, along the width direction of the strip, the lengths of the first rectifier plate 501, the second rectifier plate 502, the third rectifier plate 503, and the fourth rectifier plate 504 are all greater than the width of the strip. In this embodiment, the first rectifier plate 501, the second rectifier plate 502, the third rectifier plate 503, and the fourth rectifier plate 504 are arranged at the same height.

[0023] In this embodiment, the sinking roller 4 is arranged near the bottom of the trough body 2. Along the width direction of the trough body 2, the sinking roller 4 is located in the middle of the trough body 2. In this embodiment, the cross section of the trough body 2 in the vertical direction is divided into an upper part and a lower part, the upper part is rectangular, and the lower part is an inverted trapezoid.

[0024] In this embodiment, along the horizontal direction, the first rectifier plate 501, the second rectifier plate 502, the third rectifier plate 503, and the fourth rectifier plate 504 are all slidably connected to the inner wall of the tank body 2, so as to facilitate the adjustment of the spacing between the rectifier plate and the plate; for example, a slide groove is provided on the inner wall of the tank body 2, and a slider matching the slide groove is provided on the rectifier plate. The first rectifier plate 501, the second rectifier plate 502, the third rectifier plate 503, and the fourth rectifier plate 504 are preferably detachably connected to the tank body 2, so as to facilitate the replacement of the rectifier plate.

[0025] like Figure 2 As shown, the liquid on the left and right surfaces of the inlet strip section 101 flows downward with the inlet strip section 101. Since the distance between the first rectifying plate 501 and the inlet strip section 101 is farther than the distance between the second rectifying plate 502 and the inlet strip section 101, the liquid on the right surface of the inlet strip section 101 is less obstructed when passing through the first rectifying plate 501 when flowing downward, while the liquid on the left surface of the inlet strip section 101 is more obstructed when passing through the second rectifying plate 502. At this time, the sinking roller 4 at the lower left side of the inlet strip section 101 As the sinking roller 4 rotates clockwise, the liquid in the inlet strip 101 merges with the liquid passing through the second rectifying plate 502 in the area just before the inlet strip segment 101 contacts the sinking roller 4. By properly adjusting the spacing between the first rectifying plate 501, the second rectifying plate 502 and the inlet strip segment 101, the pressure in the fusion area here can be made equal to the pressure on the right side of the inlet strip segment 101, and the inlet strip segment 101 will not tilt to the right. Similarly, the liquid on the left and right surfaces of the outlet strip segment 102 flows upward with the outlet strip segment 102. The distance between the flow plate 504 and the outlet strip section 102 is farther than that between the third flow plate 503 and the outlet strip section 102. When the liquid on the left side of the outlet strip section 102 flows upward, it is less obstructed when passing through the fourth flow plate 504. When the liquid on the right side of the outlet strip section 102 flows upward, it is more obstructed when passing through the third flow plate 503. At this time, the liquid at the sinking roller 4 below the right side of the outlet strip section 102 will be diverted away as the sinking roller 4 rotates. The third flow plate 503 and the fourth flow plate 504 are appropriately adjusted. 04 and the distance between the outlet strip segment 102 and the outlet strip segment 102 can make the pressure in this area equal to the pressure on the left side of the outlet strip segment 102, and the outlet strip segment 102 will not tilt to the right; therefore, the application of the first rectifying plate 501, the second rectifying plate 502, the third rectifying plate 503 and the fourth rectifying plate 504 can make the strip 1 run along the ideal running trajectory before and after bypassing the sinking roller 4 (the inlet strip segment 101 moves vertically downward, and the outlet strip segment 102 moves vertically upward), and will not tilt due to the complex flow of the liquid in the tank.
