Description

Technical Field

[0001] This invention relates to the field of strip drying technology, and in particular to a strip wet leveling and drying device. Background Technology

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products. During continuous production on a cold rolling continuous annealing line, the wet leveling system will bring out a large amount of water on the surface of the leveled strip steel. In order to ensure that the strip steel is dry and does not rust, a special drying device is needed to dry the strip steel after wet leveling.

[0003] The existing drying equipment has a structure including a drying fan, heat exchanger, air box, and air outlet pipe. The drying fan, heat exchanger, air box, and air outlet pipe form an air path. The steam pipe enters the heat exchanger, so that the air blown out by the drying fan becomes hot air. The hot air is discharged from the air outlet pipe and blown onto the surface of the strip steel to be dried, thus performing the drying operation on the strip steel.

[0004] Current drying equipment has poor drying effect on strip steel. When the strip steel flows out of the wet leveling system, its surface usually carries a lot of water, and the water may even form puddles in some parts of the strip steel, making it difficult to dry using the drying equipment alone and unable to perform the drying operation effectively. Therefore, we propose a strip steel wet leveling and drying device to solve the above problems. Summary of the Invention

As the strip steel passes through the scraper, the water at the top is scraped to both sides and falls off the strip steel. Simultaneously, the motor is started, driving the second rotating shaft and transmission cylinder to rotate. The transmission cylinder drives the sponge belt, which comes into contact with the surface of the strip steel during operation, further wiping the surface. After wiping, the strip steel finally passes through the first air outlet pipe and the air outlet head. The hot air blown out by the air outlet head dries the strip steel. Through multiple dehydration operations, the strip steel is dried more thoroughly, solving the problem of poor drying effect of current drying devices.

[0018] This invention utilizes a second air outlet duct. The sponge belt wipes the steel strip, causing it to become damp. The second air outlet of the second air outlet duct also blows out hot air, which permeates the sponge belt and accelerates its drying. The baffle allows the hot air to remain inside the sponge belt for a longer period. As the air blows towards the baffle, it drives the blades and the third rotating shaft to rotate. The third rotating shaft drives the fourth rotating shaft and the first rubber wheel to rotate via a transmission wheel and a transmission belt. The first rubber wheel drives the second rubber wheel and the fifth rotating shaft to rotate. The fifth rotating shaft drives the rotating plate and the rotating column to rotate. The rotating column contacts the vertical column, causing the vertical column to rotate. The impact ball continuously strikes the sponge belt, shaking off impurities. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Reference Figures 1-8As shown, a strip wet leveling and drying device includes a blower 1, an air outlet hood 2 fixedly connected to the air outlet of the blower 1, a heat exchanger 3 fixedly connected to one end of the air outlet hood 2, a wind box 4 fixedly connected to the heat exchanger 3, and multiple first air outlet pipes 5 connected to the wind box 4. The first air outlet pipes 5 are arranged in two groups, upper and lower, and multiple air outlet heads 6 are installed on each of the first air outlet pipes 5. A strip is placed between the two groups of first air outlet pipes 5, and the air outlet heads 6 are directly facing the strip. The strip flowing through the wet leveling system passes between the first air outlet pipes 5. When the blower 1 is started, it blows air into the air outlet hood 2. The air enters the heat exchanger 3, and steam pipes installed on the side wall of the heat exchanger 3 deliver steam into the heat exchanger 3, turning the air into hot air. The hot air is concentrated in the wind box 4, and finally blown onto both sides of the strip through the air outlet heads 6 on the first air outlet pipes 5 to dry the strip.

[0031] Furthermore, such as Figure 3 As shown, the inner wall of the air outlet 6 is fixedly connected to a support block 7 via a crossbar. A connecting column 8 is fixedly connected to the top of the support block 7. Multiple fan blades 9 are fixedly connected to the surface of the connecting column 8. Multiple first air outlet holes 10 are opened at the bottom of the air outlet 6. A rotating ring 11 is fixedly connected to the outer wall of the air outlet 6. A fixed ring 12 is fixedly connected to the first air outlet pipe 5. An annular groove is opened in the fixed ring 12. The air outlet 6 is rotatably connected to the fixed ring 12 through the rotating ring 11 and the annular groove. During the process of hot air entering the air outlet 6, the hot air blows to the fan blades 9 to rotate. The fan blades 9 drive the connecting column 8, the support block 7 and the air outlet 6 to rotate. The air outlet 6 rotates in the annular groove of the fixed ring 12 through the rotating ring 11. The hot air diffuses and blows outward through the first air outlet holes 10 on the air outlet 6, so that the hot air can be blown to a larger area, resulting in a better drying effect.

[0032] Furthermore, such as Figure 4 As shown, two first vertical plates 13 are provided on one side of the first air outlet duct 5. Each of the two first vertical plates 13 is rotatably connected to a first rotating shaft 14 via a bearing. An installation rod 15 is fixed between the two first rotating shafts 14. A stop rod 16 is fixedly connected to the bottom of the installation rod 15. A scraper 17 is fixedly connected to the bottom of the installation rod 15. The bottom end of the scraper 17 contacts the surface of the strip steel. The scraper 17 is made of rubber. The cross-section of the stop rod 16 is set to be arc-shaped. The strip steel will pass through the scraper 17 before reaching the first air outlet duct 5. The scraper 17 can scrape off the water accumulated on the surface of the strip steel and scrape the water to both sides. The stop rod 16 can provide support for the scraper 17 and prevent the scraper 17 from flipping over.

[0033] Furthermore, such as Figure 4As shown, one end of the first rotating shaft 14 is fixedly connected to a rotating plate 18, a handle 19 is fixedly connected to the rotating plate 18, and a pin 20 is slidably inserted into the rotating plate 18. A hole is formed in the first vertical plate 13, and one end of the pin 20 is inserted into the hole. A circular plate 21 is fixedly connected to the other end of the pin 20. A first spring 22 is fixedly connected between the circular plate 21 and the rotating plate 18. The first spring 22 is sleeved on the outside of the pin 20. When the scraper 17 flips, i.e., scraping... When the scraper blade 17 bends in the opposite direction, it pulls the circular plate 21. The circular plate 21 reaches the insertion post 20 and leaves the insertion hole. The first spring 22 is stretched. Rotate the handle 19. The handle 19 drives the rotating plate 18 to rotate, causing the scraper blade 17 to turn into the air. Then rotate the handle 19 in the opposite direction, so that the scraper blade 17 re-contacts the strip surface and bends back to its original state, which can better scrape away water. Release the circular plate 21. Under the action of the first spring 22, the insertion post 20 is inserted into the insertion hole, which limits the scraper blade 17.

[0034] Furthermore, such as Figure 2 As shown, the middle section of the first air outlet pipe 5 is set in a V shape, and the mounting rod 15, the baffle 16 and the scraper 17 are all set in a V shape. The V-shaped first air outlet pipe 5 can be equipped with more air outlets 6 to dry the strip steel, and the V-shaped scraper 17 can guide the water on the surface of the strip steel to fall off.

[0035] Furthermore, such as Figure 5 and Figure 6 As shown, two second vertical plates 23 are provided on one side of the first air outlet duct 5. Each of the two second vertical plates 23 is rotatably connected to a second rotating shaft 24 via bearings. A motor 25 is fixedly connected to one of the second vertical plates 23. The output shaft of the motor 25 is fixedly connected to one end of the corresponding second rotating shaft 24. A transmission cylinder 26 is fixedly connected to one end of the second rotating shaft 24. A transmission belt 27 is provided between the two second vertical plates 23, and the two corresponding transmission cylinders 26 are connected by the transmission belt 27. A rotating drum 28 is connected to the transmission belt 27, and a sponge belt 29 is fixed to the surface of the transmission belt 27. The outer wall of the transmission drum 26 contacts the inner wall of the sponge belt 29. The strip steel that has been wiped by the water will reach the sponge belt 29. The motor 25 is started, and the motor 25 drives the second rotating shaft 24 to rotate. The second rotating shaft 24 reaches the rotating drum 28 to rotate. The second rotating shaft 24 reaches the sponge belt 29 through the transmission drum 26 and the transmission belt 27, so that the sponge belt 29 contacts the surface of the strip steel. The sponge belt 29 can wipe and absorb the water on the surface of the strip steel, and further remove the water from the surface of the strip steel.

[0036] Furthermore, such as Figure 6As shown, two second air outlet pipes 30 are connected and fixed to the air box 4. The second air outlet pipes 30 are respectively inserted into the corresponding sponge belts 29. The top and bottom of the second air outlet pipes 30 are provided with second air outlet holes 31. During the air outlet process of the first air outlet pipe 5, the hot air that arrives in the air box 4 will also be blown out from the second air outlet pipes 30. The second air outlet holes 31 of the second air outlet pipes 30 blow out hot air. The sponge belts 29 wipe the surface of the strip steel, causing the sponge belts 29 to become wet. The hot air accumulates in the sponge belts 29, which can accelerate the drying of the sponge belts 29.

[0037] Furthermore, such as Figure 3 and Figure 7 As shown, an L-shaped plate 32 is fixedly connected inside both the first air outlet duct 5 and the second air outlet duct 30. A sealing plate 33 is rotatably connected to the L-shaped plate 32 via a pin. A guide wheel 34 is fixedly connected to the L-shaped plate 32. A connecting rope 35 is fixedly connected to the L-shaped plate 32. The connecting rope 35 passes around the guide wheel 34, and one end of the connecting rope 35 is fixed to the sealing plate 33. During the process of hot air blowing out of the first air outlet duct 5 and the second air outlet duct 30, the hot air will first fill the first air outlet duct 5 and the second air outlet duct 30. After filling, the hot air will push open the two sealing plates 33, and the connecting rope 35 will be stretched. The hot air will blow out of the first air outlet duct 5 and the second air outlet duct 30, so that hot air will blow out from each air outlet 6 and the second air outlet 31.

[0038] Furthermore, such as Figure 7 As shown, a baffle 36 is fixedly connected to the second air outlet 30. The baffle 36 is located outside the two outermost second air outlets 31. The baffle 36 is arc-shaped and has a slot 37. A third rotating shaft 38 is rotatably connected between the inner walls of the slot 37 through a bearing. A circular block 39 is fixedly connected to the surface of the third rotating shaft 38. Multiple blades 40 are fixedly connected to the surface of the circular block 39. One of the blades 40 extends out of the slot 37. The air blown out of the outermost second air outlet 31 is blocked by the baffle 36, which prevents the hot air from entering the sponge belt 29, allowing the hot air to stay in the sponge belt 29 for a longer time, which is beneficial to the drying of the sponge belt 29. The hot air will blow the blades 40 and the circular block 39 to rotate, and the circular block 39 will drive the third rotating shaft 38 to rotate.

[0039] Furthermore, such as Figure 8As shown, a support plate 41 is fixedly connected to one end of the baffle 36. A fourth rotating shaft 42 is rotatably connected to one end of the support plate 41 via a bearing. A transmission wheel 43 is fixedly connected to the surface of both the fourth rotating shaft 42 and the surface of the third rotating shaft 38. The transmission wheels 43 are connected to the pull rod via a transmission belt 44. A first rubber wheel 45 is fixedly connected to the surface of the fourth rotating shaft 42. A fixing plate 46 is fixedly connected to the baffle 36. A fifth rotating shaft 47 is rotatably connected to the fixing plate 46 via a bearing. A second rubber wheel 48 is fixedly connected to one end of the fifth rotating shaft 47, and the second rubber wheel 48 is in close contact with the first rubber wheel 45. A rotating plate 49 is fixedly connected to the other end of the fifth rotating shaft 47. A rotating column 50 is fixedly connected to the rotating plate 49. A connecting plate 51 is fixedly connected to the fixing plate 46. A connecting shaft 52 is rotatably connected to one end of the connecting plate 51 via a bearing. A vertical column 53 is fixedly connected to the connecting shaft 52, and the bottom end of the vertical column 53 is located at the rotating column 50. On the trajectory of rotation around the fifth rotating shaft 47, a second spring 54 is fixed to the top of the vertical column 53, and an impact ball 55 is fixed to the top of the second spring 54. The third rotating shaft 38 drives the fourth rotating shaft 42 to rotate through the transmission wheel 43 and the transmission belt 44. The fourth rotating shaft 42 drives the first rubber wheel 45 to rotate, the first rubber wheel 45 drives the second rubber wheel 48 to rotate, the second rubber wheel 48 drives the fifth rotating shaft 47 and the rotating plate 49 to rotate, and the rotating plate 49 drives the rotating column 50 to rotate. During the rotation, the rotating column 50 will contact the vertical column 53. The rotating column 50 compresses the vertical column 53 to rotate around the connecting shaft 52. The vertical column 53 drives the second spring 54 and the impact ball 55 to rotate. When the rotating column 50 is not in contact with the vertical column 53, the vertical column 53 rotates back under the action of gravity. The continuous rotation of the rotating column 50 causes the impact ball 55 to move back and forth continuously. The impact ball 55 impacts the sponge belt 29, and the impact generates vibration. The vibration can cause impurities attached to the sponge belt 29 to fall off.

[0040] Working Principle: During operation, the strip steel passing through the wet leveling system flows through the first air outlet pipe 5. The blower 1 is started, blowing air into the air outlet hood 2. The air enters the heat exchanger 3, where steam pipes installed on the side wall supply steam, turning the air into hot air. The hot air is concentrated in the air box 4 and finally blown onto both sides of the strip steel through the air outlet head 6 on the first air outlet pipe 5, drying the strip steel. During the process of the hot air entering the air outlet head 6, the hot air causes the fan blades 9 to rotate, which in turn drives the connecting column 8, support block 7, and air outlet head 6 to rotate. The air outlet head 6 rotates within the annular groove of the fixed ring 12 via the rotating ring 11. The hot air diffuses outwards through the first air outlet hole 10 on the air outlet head 6, allowing the hot air to reach a wider area. For better drying, the strip steel passes through scraper 17 before reaching the first air outlet duct 5. Scraper 17 scrapes away the water accumulated on the surface of the strip steel and pushes it to both sides. The baffle 16 provides support for scraper 17 to prevent it from flipping. When scraper 17 flips, that is, when scraper 17 bends in the opposite direction, the circular plate 21 is pulled. The circular plate 21 reaches the insertion post 20 and leaves the insertion hole. The first spring 22 is stretched. The handle 19 is rotated, which drives the rotating plate 18 to rotate, causing scraper 17 to turn into the air. Then, the handle 19 is rotated in the opposite direction, so that scraper 17 re-contacts the surface of the strip steel and bends back to its original state, which can better remove water. The circular plate 21 is released. Under the action of the first spring 22, the insertion post 20 is inserted into the insertion hole to limit the scraper 17. The strip steel, after being wiped dry, reaches the sponge belt 29. Motor 25 is started, driving the second rotating shaft 24 to rotate. The second rotating shaft 24 rotates the rotating cylinder 28, and then, via the transmission cylinder 26 and transmission belt 27, reaches the sponge belt 29, bringing it into contact with the strip steel surface. The sponge belt 29 can wipe and absorb the water on the strip steel surface, further removing moisture. During the airflow process from the first air outlet duct 5, hot air from the air box 4 is also blown out from the second air outlet duct 30. The second air outlet 31 of the second air outlet duct 30 blows out hot air. The sponge belt 29 wipes the strip steel surface, causing it to become damp. The hot air accumulates inside the sponge belt 29, accelerating its drying process. The hot air then exits the first air outlet duct... During the process of 5 and the second air outlet 30, hot air first fills the first air outlet 5 and the second air outlet 30. After filling, the hot air pushes open the two sealing plates 33, and the connecting rope 35 is stretched. The hot air blows out of the first air outlet 5 and the second air outlet 30, so that each air outlet 6 and the second air outlet 31 will have hot air blowing out. The air blown out of the outermost second air outlet 31 is blocked by the baffle 36, which prevents the hot air from entering the sponge belt 29, so that the hot air stays in the sponge belt 29 for a longer time, which is beneficial to the drying of the sponge belt 29. The hot air will blow the blades 40 and the round block 39 to rotate. The round block 39 drives the third rotating shaft 38 to rotate. The third rotating shaft 38 drives the fourth rotating shaft 42 to rotate through the transmission wheel 43 and the transmission belt 44. The fourth rotating shaft 42 drives the first rubber wheel 45 to rotate.The first rubber wheel 45 drives the second rubber wheel 48 to rotate. The second rubber wheel 48 drives the fifth rotating shaft 47 and the rotating plate 49 to rotate. The rotating plate 49 drives the rotating column 50 to rotate. During rotation, the rotating column 50 contacts the vertical column 53, pressing the vertical column 50 to rotate around the connecting shaft 52. The vertical column 53 drives the second spring 54 and the impact ball 55 to rotate. When the rotating column 50 is not in contact with the vertical column 53, the vertical column 53 rotates back under the action of gravity. The continuous rotation of the rotating column 50 causes the impact ball 55 to move back and forth continuously. The impact ball 55 impacts the sponge belt 29, generating vibrations that can dislodge impurities attached to the sponge belt 29.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
