Description

Technical Field

[0001] This invention relates to the field of strip steel surface cleaning technology, specifically to a strip steel surface cleaning device for strip steel production. Background Technology

[0002] During the production of strip steel, a lot of metal shavings, oil stains and other residues remain on the surface of the strip steel after rolling. Therefore, the surface of the strip steel needs to be cleaned before leaving the factory to ensure the cleanliness of the strip steel surface.

[0003] Chinese Patent Publication No. CN118788655B discloses a steel strip cleaning machine, including a workbench. A pair of conveying components are symmetrically arranged at the top of the workbench based on a centerline, and these conveying components are used to convey the steel strip to be cleaned. A cleaning component is also arranged at the top of the workbench for rinsing the surface of the steel strip. A pair of fixing plates are arranged at the top of the workbench between the pair of conveying components. A receiving frame is arranged on the side of the fixing plate facing the center of the workbench, and a first detection plate is slidably connected to the surface of the receiving frame. A first guide rod is provided through one end of the receiving frame. A first spring is sleeved on the surface of the first guide rod. A pressure sensor is arranged at the other end of the receiving frame. The pressure sensor is electrically connected to the controller of the conveying components. A pair of supports are symmetrically arranged at the top of the first detection plate based on a centerline, and a second guide rod is inserted through the top of the supports. A second detection plate is arranged at the bottom end of the second guide rod. A second spring is arranged between the second detection plate and the top of the supports.

[0004] The above-mentioned solution uses a straight-line cleaning method to clean the strip steel, but it occupies a large area. In the existing technology, in order to reduce the footprint of the equipment, a concave layout design is adopted, consisting of multiple cleaning grooves. Each cleaning groove is equipped with rollers to guide the strip steel. During cleaning, the strip steel enters different grooves in sequence, bends under the guidance of the rollers, and is conveyed. The main processes include pre-degreasing, brushing, electrolytic degreasing, rinsing, and drying. In the pre-degreasing process, a large amount of metal debris is attached to the surface of the strip steel. During the pre-degreasing process, the debris is washed off. The bottom of the cleaning groove in the pre-degreasing process has a bend in the strip steel, and rollers are set on the bend. The washed-off debris falls between the rollers and the strip steel, resulting in a large amount of debris between the rollers and the strip steel. This causes the rollers to slip easily when conveying the strip steel, and the debris also wears the outer circumference of the rollers. In addition, the debris also wears the surface of the strip steel, making the surface of the strip steel prone to scratches. Summary of the Invention

[0005] To address the aforementioned problems, a strip surface residue cleaning device for strip steel production is provided. By optimizing the structure of the strip surface residue cleaning device, a rotating roller composed of multiple support columns with gaps between adjacent support columns is used in conjunction with a first and second sprayer on the inner side of the "V"-shaped strip steel. The first and second sprayers rinse the inner surface of the strip steel. The rinsed water flow carries debris to the lower part of the strip steel and flows to both sides along the width direction of the strip steel. The gaps between the support columns guide the water flow that accumulates at the lower part of the strip steel, preventing obstruction when the water flow moves to both sides along the width direction of the strip steel, and preventing debris from being rolled into the rotating roller and the strip steel.

[0006] To address the problems of the prior art, the present invention provides a strip steel surface residue cleaning device for strip steel production, including a cleaning tank for cleaning the strip steel, with a feed end for the strip steel to enter and a discharge end for the strip steel to exit on both sides.

[0016] The fourth sprayer is located on one side of the second sprayer, and the strip steel passes between the second sprayer and the fourth sprayer. The cleaning unit is located below the second sprayer and the fourth sprayer.

[0017] The cleaning unit includes a cleaning brush and a second rotary drive;

[0018] There are two cleaning brushes. The strip steel passes between the two cleaning brushes and contacts each of the two cleaning brushes. The cleaning brushes rotate around their own axis during cleaning.

[0019] The second rotary driver is located at the end of the cleaning brush and is used to drive the cleaning brush to rotate.

[0020] Preferably, the cleaning unit further includes a first baffle and a second baffle;

[0021] The first baffle is vertically positioned at the bottom of the cleaning brush, and the upper part of the first baffle extends into the bristles of the cleaning brush.

[0022] The second baffle is positioned parallel to one side of the first baffle.

[0023] Preferably, a fifth sprayer is provided on the upper part of the second baffle, and the fifth sprayer sprays the side wall of the second baffle.

[0024] Preferably, a second belt drive assembly is provided at the ends of the rotating roller and the conveying roller. The conveying roller drives the rotating roller to rotate through the second belt drive assembly. In a unit time, the outer circumferential rotation length of the rotating roller is the same as that of the conveying roller.

[0025] Preferably, the cleaning tank is also equipped with a discharge unit, which includes an oil sludge tank and a chip removal unit;

[0026] The oil sludge tank is located on the side wall of the cleaning tank;

[0036] The advantages of this invention compared to the prior art are:

[0037] 1. This invention optimizes the structure of the strip steel surface residue cleaning equipment by utilizing a rotating roller composed of multiple support columns with gaps between adjacent columns, in conjunction with a first and second sprayer on the inner side of the "V"-shaped strip steel. The first and second sprayers rinse the inner surface of the strip steel, and the rinsed water flow carries debris to the lower part of the strip steel, flowing outwards along the width of the strip steel. The gaps between the support columns guide the water flow that accumulates at the lower part of the strip steel, preventing obstruction as the water flows outwards along the width of the strip steel. This prevents debris from being drawn into the rotating roller and the strip steel, reducing wear on the surface of the rotating roller and ensuring the quality of the strip steel output. This also ensures that the equipment's footprint remains unchanged while preventing debris from accumulating on the lower inner side of the strip steel and allowing it to drain freely.

[0038] 2. First, the strip surface is rinsed by the first and third sprayers to reduce the adhesion of debris and oil stains. Then, two cleaning brushes are used to clean the strip surface, which improves the cleaning effect of the strip surface in the pre-degreasing step, reduces the burden of subsequent cleaning processes, and also improves the cleaning effect. In addition, by setting the second and fourth sprayers and placing them above the cleaning brushes, it is ensured that when the cleaning brushes clean the strip surface, the clean water can have a rinsing effect on the strip surface, so that the debris and oil stains are washed away in time.

[0054] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0055] Reference Figures 1-4 and Figures 6-8 A strip steel surface residue cleaning device for strip steel production includes a cleaning tank 1 for cleaning strip steel 2, with a feed end for the strip steel 2 to enter and a discharge end for the strip steel 2 to exit on both sides.

[0056] The cleaning tank 1 is equipped with a rotating roller 11, a conveying roller 12, a first rotary driver 121, a first sprayer 13, and a second sprayer 14;

[0057] The rotating roller 11 is rotatably disposed in the cleaning groove 1 along the width direction of the cleaning groove 1. The rotating roller 11 is composed of multiple support columns 111 arranged in a ring. There is a gap between adjacent support columns 111. The axis of the support column 111 is parallel to the width direction of the cleaning groove 1. The support column 111 is in contact with the strip steel 2. The strip steel 2 is wound around the lower part of the rotating roller 11.

[0058] There are two conveying rollers 12, both located above the rotating roller 11. The two conveying rollers 12 are symmetrically arranged about the rotating roller 11. The strip steel 2 is wound around the upper part of the conveying rollers 12, and the strip steel 2 located in the cleaning groove 1 is in a "V" shape.

[0059] The first rotary driver 121 is disposed at the end of the conveying roller 12 and is used to drive the conveying roller 12 to rotate;

[0060] The first sprayer 13 and the second sprayer 14 are both installed in the cleaning trough 1 and located inside the “V”-shaped strip 2. The first sprayer 13 is located on the side of the rotating roller 11 near the feed end, and the second sprayer 14 is located on the side of the rotating roller 11 near the discharge end.

[0061] Existing surface cleaning processes for steel strip 2 mainly include pre-degreasing, brushing, electrolytic degreasing, rinsing, and drying. This invention primarily focuses on optimizing the equipment used in pre-degreasing. Since pre-degreasing is the first step in the entire surface cleaning process for steel strip 2, a large amount of debris and oil will adhere to its surface. The pre-degreasing process is mainly for preliminary cleaning of the oil and debris on the surface of steel strip 2. This process primarily uses low-pressure water rinsing, but this results in a large amount of debris being washed away from the surface of steel strip 2. Because the existing process uses cleaning trough 1 to clean the surface of strip steel 2, thereby reducing the footprint of the equipment, it causes strip steel 2 to bend in cleaning trough 1, forming a "V" shaped structure. The debris washed down on the inner side of strip steel 2 accumulates at the bottom of the inner side of strip steel 2. As a result, when the rotating roller 11 rotates and conveys strip steel 2, a large amount of debris is mixed between the rotating roller 11 and strip steel 2 and is not easy to be discharged. When the debris is rolled into the rotating roller 11, the debris will not only scratch the surface of strip steel 2, but also cause the peripheral wall of the rotating roller 11 to become out of round due to wear, thereby further increasing the wear of the rotating roller 11.

[0062] To avoid the above situation, the structure of the existing strip steel 2 surface cleaning equipment was optimized. This optimized design ensures that while cleaning the strip steel 2, the cleaning tank 1 is still used. This prevents the debris from accumulating on the lower inner side of the strip steel 2, allowing it to discharge freely and avoiding wear on the rotating roller 11 and the surface of the strip steel 2, thus guaranteeing the output quality of the strip steel 2. The specific structure and working process of this invention are as follows:

[0063] The support column 111 is made of highly elastic polyurethane material, whose elastic deformation capability can absorb the impact force during contact, significantly reducing local contact stress. Experimental verification shows that the contact stress between the support column 111 and the strip steel 2 is ≤20MPa, far lower than the yield strength of ordinary strip steel (300MPa). First, the strip steel 2 is fed into the cleaning trough 1 from the feed end. The strip steel 2 passes over the upper part of the conveyor roller 12 near the feed end and extends into the cleaning trough 1. Then, it passes over the lower part of the rotating roller 11 and is lifted. Finally, it passes over the upper part of the conveyor roller 12 near the discharge end and is discharged from the discharge end. The conveyor roller 12 is driven to rotate by a first rotary driver 121. To ensure the synchronicity of the rotation of the two conveyor rollers 12, a first belt drive assembly 122 is provided at the ends of the two conveyor rollers 12. The two conveyor rollers 12 are driven and cooperate through the first belt drive assembly 122, thus achieving synchronous rotation of the two conveyor rollers 12 with only one first rotary driver 121. The first rotary driver 121 is preferably a servo motor. A first sprayer 13 and a second sprayer 14 are also installed in the cleaning tank 1. The first sprayer 13 and the second sprayer 14 can clean the inner surface of the strip 2. The inner surface of the strip 2 refers to the upper end face of the strip 2. The first sprayer 13 and the second sprayer 14 spray low-pressure water onto the inner surface of the strip 2. The water flow washes the inner surface of the strip 2, causing the debris attached to the inner surface of the strip 2 to flow down with the water flow. Since the rotating roller 11 is composed of multiple support columns 111, there are gaps between adjacent support columns 111. The gaps extend to both sides along the width of the strip 2. When debris on the inner surface of the strip 2 flows down with the water, it gathers at the bottom of the strip 2. Guided by the gaps between adjacent support columns 111, the water flows to both sides of the strip 2. The debris gathered at the bottom of the strip 2 is washed out by the water flow. Compared to the traditional rotating roller 11, the rotating roller 11 composed of support columns 111 has a macroscopic line contact with the surface of the strip 2, while the driving rotating roller 11 has a surface contact with the strip 2. Therefore, debris is more easily drawn into the space between the rotating roller 11 and the strip 2. At the same time, since the rotating roller 11 is composed of multiple support columns 111, there are multiple gaps on the rotating roller 11, which facilitates the discharge of water. This avoids the wear caused to the surface of the strip 2 and the rotating roller 11 by the accumulation of debris at the bottom of the strip 2.

[0064] By optimizing the structure of the strip steel 2 surface residue cleaning equipment, a rotating roller 11 composed of multiple support columns 111 with gaps between adjacent support columns 111 is used in conjunction with a first sprayer 13 and a second sprayer 14 on the inner side of the "V"-shaped strip steel 2. The first sprayer 13 and the second sprayer 14 rinse the inner surface of the strip steel 2. The rinsed water flow carries the debris to the lower part of the strip steel 2 and flows to both sides along the width direction of the strip steel 2. The gaps between the support columns 111 can guide the water flow that gathers at the lower part of the strip steel 2, avoiding obstruction when the water flow moves to both sides along the width direction of the strip steel 2. This prevents debris from being rolled into the rotating roller 11 and the strip steel 2, reduces wear on the surface of the rotating roller 11 and the strip steel 2, and ensures the output quality of the strip steel 2. This ensures that the equipment footprint remains unchanged and that the cleaning debris does not accumulate in the lower inner part of the strip steel 2 and can be discharged freely.

[0065] Reference Figure 12 A set of limiting components is provided on both the rotating roller 11 and the conveying roller 12. Each set of limiting components includes two limiting rings 15 arranged along the width direction of the strip 2. The straight distance between the two limiting rings 15 is the same as the width of the strip 2.

[0066] The limiting ring 15 limits the two sides of the strip steel 2, preventing the strip steel 2 from shaking during the conveying process.

[0067] Reference Figure 8 A third sprayer 16 is provided on one side near the feed end of the cleaning tank 1. The third sprayer 16 is located on one side of the first sprayer 13, and the strip steel 2 passes between the first sprayer 13 and the third sprayer 16.

[0068] The first sprayer 13 and the third sprayer 16 are both located on the side of the rotating roller 11 near the feed end. When the strip 2 passes between the first sprayer 13 and the third sprayer 16, the first sprayer 13 and the third sprayer 16 can spray and rinse the upper and lower ends of the strip 2 respectively. It is worth noting that a certain amount of cleaning liquid can be added to the clean water during rinsing to improve the pre-degreasing effect on the strip 2.

[0069] Reference Figure 11 , Figure 13 and Figure 14 The cleaning tank 1 is also equipped with a cleaning unit 17 and a fourth sprayer 18;

[0070] The cleaning unit 17 is located on the side of the rotating roller 11 near the discharge end;

[0071] The fourth sprayer 18 is located on one side of the second sprayer 14, the strip steel 2 passes through the space between the second sprayer 14 and the fourth sprayer 18, and the cleaning unit 17 is located below the second sprayer 14 and the fourth sprayer 18.

[0072] The cleaning unit 17 includes a cleaning brush 171 and a second rotary driver 172;

[0073] Two cleaning brushes 171 are provided. The strip steel 2 passes between the two cleaning brushes 171 and contacts the two cleaning brushes 171 respectively. The cleaning brushes 171 rotate around their own axis when cleaning.

[0074] The second rotary driver 172 is disposed at the end of the cleaning brush 171 and is used to drive the cleaning brush 171 to rotate.

[0075] The cleaning unit 17 also includes two transmission gears 173, which are fixedly mounted on the ends of the two cleaning brushes 171. Thus, only one second rotary driver 172 is needed to drive the two cleaning brushes 171. The second rotary driver 172 is preferably a servo motor. First, the surface of the strip steel 2 is rinsed by the first sprayer 13 and the third sprayer 16, which reduces the adhesion of debris and oil stains on the surface of the strip steel 2. Then, the surface of the strip steel 2 is cleaned by the two cleaning brushes 171, which improves the cleaning effect of the surface of the strip steel 2 in the pre-degreasing step, reduces the burden of subsequent cleaning processes, and also improves the cleaning effect. In addition, by setting the second sprayer 14 and the fourth sprayer 18 and positioning the second sprayer 14 and the fourth sprayer 18 above the cleaning brushes 171, it is ensured that when the cleaning brushes 171 clean the surface of the strip steel 2, the clean water can have a rinsing effect on the surface of the strip steel 2, so that the debris and oil stains that are cleaned off can be washed away in time.

[0076] Reference Figure 5 and Figure 11 The cleaning unit 17 also includes a first baffle 174 and a second baffle 175;

[0077] The first baffle 174 is vertically disposed at the lower part of the cleaning brush 171, and the upper part of the first baffle 174 extends into the bristles of the cleaning brush 171.

[0078] The second baffle 175 is arranged parallel to one side of the first baffle 174.

[0079] When the cleaning brush 171 rotates, the bristles on the cleaning brush 171 clean the surface of the strip steel 2. Some debris gets stuck in the bristles of the cleaning brush 171. When the bristles pass the first baffle 174, the upper part of the first baffle 174 extends into the bristles of the cleaning brush 171, causing the bristles to bend due to the obstruction of the first baffle 174 when the cleaning brush 171 rotates. After the bristles have completely passed the first baffle 174, they will return to their original shape. The elasticity of the bristles themselves will fling out the debris stuck in the bristles. The second baffle 175, which is located on one side of the first baffle 174, is used to intercept the flung debris and prevent the debris from flying everywhere when the first baffle 174 cleans the bristles of the cleaning brush 171.

[0080] Reference Figure 5 and Figure 13 A fifth sprayer 176 is provided on the upper part of the second baffle 175, and the fifth sprayer 176 sprays water onto the side wall of the second baffle 175.

[0081] The fifth sprayer 176 sprays water onto the side wall of the second baffle 175, ensuring that debris does not remain on the side wall of the second baffle 175 in large quantities.

[0082] Reference Figure 2 A second belt drive assembly 112 is provided at the ends of the rotating roller 11 and the conveying roller 12. The conveying roller 12 drives the rotating roller 11 to rotate through the second belt drive assembly 112. In a unit time, the outer circumferential rotation length of the rotating roller 11 is the same as the outer circumferential rotation length of the conveying roller 12.

[0083] By setting the second belt drive assembly 112, the outer circumferential rotation length of the rotating roller 11 is the same as that of the conveying roller 12 per unit time, which reduces the slippage between the rotating roller 11 and the strip 2.

[0084] Reference Figure 1 , Figure 3 and Figure 4 The cleaning tank 1 is also equipped with a discharge unit 3, which includes an oil tank 31 and a chip removal unit 32.

[0085] The oil sludge tank 31 is located on the side wall of the cleaning tank 1;

[0086] The chip removal unit 32 is located at the bottom of the cleaning tank 1 and is used to discharge the debris that sinks to the bottom of the cleaning tank 1.

[0087] Because the surface of the strip steel 2 is covered with oil, after rinsing, some of the oil will flow into the bottom of the cleaning tank 1 with the water and accumulate. The oil and water will separate into layers at the bottom of the cleaning tank 1. The oil on the upper layer will be discharged from the oil tank 31 with some of the overflowing water. This is because the water sprayed by the first sprayer 13, the second sprayer 14, the third sprayer 16, and the fourth sprayer 18 will all fall into the bottom of the cleaning tank 1, causing the water level at the bottom of the cleaning tank 1 to rise continuously, ensuring that water can continuously overflow from the oil tank 31. The chip removal unit 32 installed at the bottom of the cleaning tank 1 can periodically discharge the debris.

[0088] Reference Figure 11 The chip removal unit 32 includes a collection shell 321, a spiral blade 322, and a third rotary actuator 323;

[0089] The collection shell 321 is disposed on one side of the cleaning tank 1 and is connected to the cleaning tank 1;

[0090] The spiral blades 322 are rotatably disposed at the bottom of the cleaning tank 1 along the arrangement direction of the collection shell 321 and the cleaning tank 1;

[0091] The third rotary actuator 323 is disposed at the end of the helical blade 322 and is used to drive the helical blade 322 to rotate.

[0092] The third rotary drive 323 is preferably a servo motor. The third rotary drive 323 is used to periodically drive the spiral blade 322 to rotate, and the spiral blade 322 discharges the debris that has settled at the bottom of the cleaning tank 1 into the collection shell 321.

[0093] Reference Figure 9 and Figure 10 The collecting shell 321 includes a temporary storage chamber 3211 and a discharge chamber 3212. The temporary storage chamber 3211 contains a mixture of debris and water, and the discharge chamber 3212 contains dehydrated debris. The chip removal unit 32 includes a slide table 324, a winding device 325, and an electromagnet 326.

[0094] The slide table 324 is arranged on the upper part of the collection shell 321 along the arrangement direction of the temporary storage chamber 3211 and the discharge chamber 3212;

[0095] The winder 325 is located at the lower part of the slide table 324, and a traction rope is wound on the winder 325;

[0096] Electromagnet 326 is fixedly mounted at the lower end of the traction rope.

[0097] First, the spiral blades 322 discharge the debris from the cleaning trough 1 into the temporary storage cavity 3211 of the collection shell 321. Then, the slide table 324 drives the winding device 325 to move directly above the temporary storage cavity 3211. The winding device 325 releases the traction rope, causing the electromagnet 326 to descend. The electromagnet 326 is energized during descent and attracts the debris. Then, the winding device 325 winds up the traction rope, causing the electromagnet 326 to rise. Afterward, the slide table 324 drives the winding device 325 to move from directly above the temporary storage cavity 3211 to directly above the discharge cavity 3212. The electromagnet 326 is de-energized, and the debris attracted on the electromagnet 326 automatically falls into the discharge cavity 3212. The bottom of the discharge cavity 3212 is an inclined structure, and an opening is provided on the lower side of the inclined structure. The debris is discharged through the opening.

[0098] Working principle: First, the strip steel 2 is fed into the cleaning trough 1 from the feed end. The strip steel 2 passes over the upper part of the conveying roller 12 near the feed end and extends into the cleaning trough 1. Then, it passes over the lower part of the rotating roller 11 and is lifted. Finally, it passes over the upper part of the conveying roller 12 near the discharge end and is discharged from the discharge end. The conveying roller 12 is driven to rotate by the first rotary driver 121. To ensure the synchronicity of the rotation of the two conveying rollers 12, a first belt drive assembly 122 is provided at the ends of the two conveying rollers 12. The two conveying rollers 12 are driven and cooperate through the first belt drive assembly 122. Thus, the synchronous rotation of the two conveying rollers 12 can be achieved with only one first rotary driver 121. The first rotary driver 121 is preferably a servo motor. A first sprayer 13 and a second sprayer 14 are also installed in the cleaning tank 1. The first sprayer 13 and the second sprayer 14 can clean the inner surface of the strip 2. The inner surface of the strip 2 refers to the upper end face of the strip 2. The first sprayer 13 and the second sprayer 14 spray low-pressure water onto the inner surface of the strip 2. The water flow washes the inner surface of the strip 2, causing the debris attached to the inner surface of the strip 2 to flow down with the water flow. Since the rotating roller 11 is composed of multiple support columns 111, there are gaps between adjacent support columns 111. The gaps extend to both sides along the width of the strip 2. When debris on the inner surface of the strip 2 flows down with the water, it gathers at the bottom of the strip 2. Guided by the gaps between adjacent support columns 111, the water flows to both sides of the strip 2. The debris gathered at the bottom of the strip 2 is washed out by the water flow. Compared to the traditional rotating roller 11, the rotating roller 11 composed of support columns 111 has a macroscopic line contact with the surface of the strip 2, while the driving rotating roller 11 has a surface contact with the strip 2. Therefore, debris is more easily drawn into the space between the rotating roller 11 and the strip 2. At the same time, since the rotating roller 11 is composed of multiple support columns 111, there are multiple gaps on the rotating roller 11, which facilitates the discharge of water. This avoids the wear caused to the surface of the strip 2 and the rotating roller 11 by the accumulation of debris at the bottom of the strip 2.
