Description

Technical Field

[0001] This utility model belongs to the field of hot-rolled steel coil technology, specifically a pickling and galvanizing mechanism. Background Technology

[0002] Hot-rolled steel coils are steel products that have been hot-rolled into coils. In order to improve the quality and service life of steel coils, they usually need to undergo pickling and galvanizing treatment. Therefore, a pickling and galvanizing facility is required to process the steel coils.

[0003] Among them, a search revealed an application with application number CN202222221393.1, which discloses a steel strip galvanizing device, including a galvanizing box body, a galvanizing mechanism inside the galvanizing box body, and a controller to control the feeding mechanism to feed the nozzles inside the galvanizing box body, so that the galvanizing liquid is drawn from the nozzles to the steel strip pulled by the traction roller group for galvanizing treatment, and then dried by the drying fan set at the discharge port, which greatly improves the production efficiency. The galvanizing box body is provided with a discharge hole for easy discharge of waste liquid, which is located at the bottom of the waste liquid recovery tank. The collected waste liquid is discharged and recycled through the discharge hole. The drying fan is fixedly set on the inner wall of the galvanizing box body at the discharge port position, which is used to air dry the steel strip after galvanizing, and prevent the un-flowed galvanizing liquid from scattering to the outside of the equipment, thereby ensuring the advantage of a hygienic production environment.

[0004] However, research has revealed that the device lacks a pickling structure for the steel strip before galvanizing. Oxides, rust, grease, and other contaminants on the steel strip surface can affect the galvanizing effect. Furthermore, during galvanizing, molten zinc is also sprayed onto the lower surface of the steel strip through a nozzle. The molten zinc flows downwards due to gravity, which can affect the galvanizing effect on the lower surface of the steel strip, resulting in an unsatisfactory galvanizing effect. Therefore, a new type of device is proposed to solve this problem. Utility Model Content

[0010] The galvanizing mechanism includes a zinc bath, a zinc pump, a galvanizing tank, a conveying roller B, a motor D, a connecting plate, a servo cylinder C, a guide funnel, a nozzle, and a guide roller B. A zinc bath is embedded on the other side of the support frame. A zinc pump is installed at the outlet of the zinc bath, and a zinc delivery pipe is connected to the outlet of the pump. A connecting plate is installed below the crossbeam, corresponding to the zinc bath, via the servo cylinder C. The lower surface of the connecting plate is arc-shaped.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In this utility model:

[0024] Reference Figure 1-6A pickling and galvanizing mechanism includes a support frame 1, a steel coil frame 101 fixedly installed on one side of the upper part of the support frame 1, a motor A1011 installed on one side of the steel coil frame 101, and the output shaft of the motor A1011 connected to the steel coil shaft through a coupling. A cross frame 102 is fixedly installed on the upper part of the support frame 1.

[0025] Above the support frame 1 is a pickling mechanism for better pickling effect and a galvanizing mechanism for uniform galvanizing.

[0026] Reference Figure 1 , 2 6. In this embodiment, the pickling mechanism includes a servo cylinder A1021, an acid solution tank 103, a connecting frame 1031, a guide roller A1032, a guide groove 1033, a brush roller 1034, a motor B1035, and a scraper groove 1036. The acid solution tank 103 is embedded above the support frame 1 near the steel coil frame 101. The connecting frame 1031 is installed below the cross frame 102 at a position corresponding to the acid solution tank 103 via the servo cylinder A1021. The connecting frame 1031 rotates downwards. A guide roller A1032 is connected, and a guide groove 1033 is fixedly installed on one side of the connecting frame 1031. Brush rollers 1034 are symmetrically connected to the two sides inside the guide groove 1033 via motor B1035. Several bristles are arranged around the outer wall of the brush roller 1034. The bristles of the brush roller 1034 are made of nylon and PPS. A wiper groove 1036 is fixedly installed on one side of the connecting frame 1031. Rubber pads are symmetrically glued to the two sides inside the wiper groove 1036.

[0027] Motor A1011 operates, driving the steel coil reel to rotate and unwind the steel coil. With the assistance of a worker, the starting end of the steel coil on the coil holder 101 is pulled past the bottom of guide roller A1032, then through guide groove 1033, and finally through the scraper groove 1036. Servo cylinder A1021 extends, pushing connecting frame 1031 and guide roller A1032 downwards, pressing the steel strip below guide roller A1032 into the acid solution tank 103. The pickling solution inside the acid solution tank 103 contacts the steel strip, pickling it and removing the oxide from the steel strip surface. The pickling process removes impurities, rust, grease, and other contaminants, making the metal surface clean, smooth, and shiny. The steel strip passes through the guide groove 1033, and the motor B1035 drives the brush roller 1034 to rotate in the opposite direction to the movement of the steel strip. The bristles on the surface of the brush roller 1034 continuously rub the surface of the steel strip, making it easier for impurities adhering to the surface of the steel strip to be removed, resulting in a better pickling effect. The steel strip passes through the scraper groove 1036, and the rubber pads on both sides inside the scraper groove 1036 clamp the surface of the steel strip. As the steel strip moves, excess acid solution is scraped off the surface of the steel strip.

[0028] Reference Figure 1 , 2In this embodiment, a water tank 104 is installed through the top of the support frame 1, and a water pump 1041 is installed at the outlet of the water tank 104. A guide pulley 1022 is rotatably connected to the bottom of the cross frame 102 at the corresponding position of the water tank 104. Sprayers 1042 are symmetrically fixed on both sides of the inlet of the water tank 104, and the sprayers 1042 are inclined. The sprayers 1042 are connected to the water pump 1041 by pipe. A scraper rubber pad 1043 is symmetrically glued to one side of the water tank 104 through an opening.

[0029] With the help of staff, the starting end of the steel coil is passed over the guide pulley 1022, then through the two spray frames 1042, and then out through the opening on one side of the water tank 104. The water pump 1041 works, continuously spraying clean water from inside the water tank 104 through the spray frames 1042 onto both sides of the steel strip to clean and remove the acid solution from the surface of the steel strip. The steel strip passes through the opening on one side of the water tank 104, where the scraper rubber pads 1043 inside the opening hold the steel strip on the upper and lower sides to scrape off excess water from the surface of the steel strip.

[0030] Reference Figure 1 , 2 5. In this embodiment, a drying trough 105 is fixedly installed above the support frame 1 near the water tank 104, and the inlet and outlet of the drying trough 105 are on the same horizontal line as the opening on one side of the water tank 104. A limit plate 1051 is installed inside the drying trough 105 near the upper edge via a servo electric cylinder B1052. Conveyor rollers A106 are equidistantly embedded and rotatably connected below the limit plate 1051 and at the lower edge inside the drying trough 105. Adjacent conveyor rollers A106 are connected by chain drive, and a nested structure is provided outside the conveyor rollers A106. The chain-engaged sprockets, the drying tank 105 and the limiting plate 1051 are both equipped with motors C1061, and the output shaft of motor C1061 is connected to the corresponding conveyor roller A106 through a coupling. The surface of conveyor roller A106 is provided with several punches. A hot air blower 1053 is embedded in the outside of the drying tank 105. The drying tank 105 and the limiting plate 1051 are both provided with cavities. Part of the conveyor roller A106 is inserted into the cavity. The outlet of the hot air blower 1053 extends into the cavity through a pipe.

[0031] With the assistance of staff, the starting end of the steel coil is inserted into the inlet on one side of the drying tank 105. The servo cylinder B1052 extends, driving the limiting plate 1051 to move downward. This causes the conveying roller A106 below the limiting plate 1051 and the conveying roller A106 at the lower edge of the drying tank 105 to clamp the starting end of the steel coil on the upper and lower sides, respectively. The motor C1061 drives the conveying roller A106 to rotate, slowly moving the clamped starting end of the steel coil, thereby causing the entire steel strip to move slowly. The hot air blower 1053 works, and the generated hot air is introduced into the cavity through the pipe. Then, it is blown onto the surface of the steel strip through the punched holes on the surface of the conveying roller A106 to dry the residual moisture on the surface of the steel strip, resulting in a better drying effect.

[0032] Reference Figure 1-4 In this embodiment, the galvanizing mechanism includes a zinc bath 2, a zinc pump 201, a galvanizing tank 202, a conveying roller B2021, a motor D2022, a connecting plate 203, a servo cylinder C2031, a guide funnel 2032, a nozzle 2033, a guide roller B2034, and a servo cylinder D205. A zinc bath 2 is embedded on the other side above the support frame 1. A zinc pump 201 is installed at the outlet of the zinc bath 2, and a zinc delivery pipe is connected to the outlet of the zinc pump 201. A connecting plate 203 is installed below the crossbeam 102 at a position corresponding to the zinc bath 2 via the servo cylinder C2031, and the lower surface of the connecting plate 203 is arc-shaped. The galvanizing tank 202 is connected below the crossbeam 102 via the servo cylinder D205, and the bottom of the galvanizing tank 202 is cylindrical, and the galvanizing tank 202 as a whole is V-shaped. The surface of the galvanizing tank 202 has an opening that fits into the connecting plate 203. A guide roller B2034 is rotatably connected below the connecting plate 203. A through groove is provided on the bottom surface of the galvanizing tank 202. Conveying rollers B2021 are symmetrically and equidistantly rotatably connected to both sides of the galvanizing tank 202. Adjacent conveying rollers B2021 are connected by chain drive. A sprocket that meshes with the chain is nested outside the conveying rollers B2021. Motors D2022 are symmetrically installed on both sides of the galvanizing tank 202 near the upper edge. The output shaft of motor D2022 is connected to the corresponding conveying roller B2021. A nozzle 2033 is fixedly installed on one side below the connecting plate 203. A guide funnel 2032 is fixedly installed on the upper part of the connecting plate 203 at the position corresponding to the zinc liquid conveying pipe outlet. A cavity communicating with the inner cavity of the nozzle 2033 and the guide funnel 2032 is provided inside the connecting plate 203.

[0033] With the assistance of workers, the starting end of the steel coil is inserted into the entrance on one side of the galvanizing tank 202. Then, motor D2022 operates, driving conveyor roller B2021 to rotate, clamping the starting end of the steel coil and slowly moving it along the galvanizing tank 202 until it reaches the lowest point within the tank. Workers then assist in inserting the starting end of the steel coil through the gap in conveyor roller B2021 on the other side of the galvanizing tank 202. Next, servo cylinder C2031 extends, causing connecting plate 203 to move downwards and lock into the opening above the galvanizing tank 202. Workers then secure connecting plate 203 to the opening of the galvanizing tank 202 using fixing bolts. Simultaneously, servo cylinders D205 and C2031 extend, pushing... The moving galvanizing tank 202 moves down into the zinc bath 2, immersing the lowest point of the galvanizing tank 202 into the zinc bath. The zinc bath 202 enters the galvanizing tank 202 through the through groove at the bottom of the galvanizing tank 202, and coats the lower surface of the steel strip with zinc. The zinc pump 201 operates, guiding the zinc bath 202 into the guide funnel 2032 through the zinc bath delivery pipe, and then into the cavity of the nozzle 2033. The zinc bath 2033 is then sprayed onto the upper surface of the steel strip, galvanizing the upper surface of the steel strip. The motor D2022 continues to operate, driving the conveyor roller B2021 to rotate, clamping the steel strip and moving it slowly, so that the steel strip is evenly coated with zinc.

[0034] Reference Figure 1-3 In this embodiment, a cooler 204 is fixedly installed on one side above the support frame 1. An air outlet 2041 is symmetrically embedded inside the galvanizing tank 202 on the side near the nozzle 2033. The air outlet 2041 is connected to the cooler 204 through a pipe. An air guide is provided on the surface of the galvanizing tank 202 near the air outlet 2041.

[0035] When the air cooler 204 is working, it blows the generated cold air onto the surface of the steel strip through the air outlet 2041, causing the zinc liquid on the surface of the steel strip to solidify and dry quickly.

[0036] Reference Figure 1-6 In this embodiment, motor A1011, servo electric cylinder A1021, motor B1035, water pump 1041, servo electric cylinder B1052, hot air blower 1053, motor C1061, zinc pump 201, motor D2022, servo electric cylinder C2031 and cold air blower 204 are all electrically connected to an external power supply through a switch panel.

[0037] Working principle: First, motor A1011 operates, driving the steel coil shaft to rotate and unwind the steel coil. Then, with the assistance of the operator, the starting end of the steel coil on the steel coil holder 101 is pulled over the bottom of the guide roller A1032, then passes through the guide groove 1033, and then through the inside of the scraper groove 1036. The operator helps to fix the starting end of the steel coil. The servo cylinder A1021 extends, pushing the connecting frame 1031 and the guide roller A1032 downward, pressing the steel strip below the guide roller A1032 into the acid solution tank 103. Then, with the assistance of the operator, the starting end of the steel coil is passed over the guide pulley 1022, then passes between the two spray frames 1042, then exits through the opening on one side of the water tank 104, and enters through the inlet on one side of the drying tank 105. The servo cylinder B1052 extends, causing the limiting plate 1051 to move downwards. This causes the conveyor roller A106 below the limiting plate 1051 and the conveyor roller A106 at the lower edge of the drying tank 105 to clamp the starting end of the steel coil on both sides, fixing the starting end of the steel coil inside the drying tank 105. Then, the motor C1061 drives the conveyor roller A106 to rotate, slowly moving the clamped starting end of the steel coil, thereby causing the entire steel strip to move slowly. The pickling solution inside the acid solution tank 103 comes into contact with the steel strip, pickling it and removing oxides, rust, grease, and other contaminants from the surface of the steel strip. The motor B1035 drives the brush roller 1034 to rotate in the opposite direction to the movement of the steel strip. The bristles on the surface of the brush roller 1034 continuously rub against the surface of the steel strip, making... Impurities adhering to the steel strip surface are more easily removed, resulting in better pickling effect. The steel strip passes through the scraper groove 1036, where rubber pads on both sides of the groove hold the steel strip surface. As the steel strip moves, excess acid solution is scraped off. The water pump 1041 continuously sprays clean water from the water tank 104 onto both sides of the steel strip through the spray frame 1042, cleaning and removing the acid solution from the steel strip surface. The steel strip passes through an opening on one side of the water tank 104, where scraper rubber pads 1043 hold the steel strip on the upper and lower sides, scraping off excess water from the surface. Simultaneously, the hot air blower 1053 operates, generating hot air that is introduced into the cavity through pipes and then blown onto the steel strip surface through the perforations on the surface of the conveyor roller A106, further removing residual moisture. To improve the drying effect, the steel coil, starting from the outlet of the drying tank 105, is then inserted into the galvanizing tank 202 from one side through the entrance. Motor D2022 then operates, driving conveyor roller B2021 to rotate, slowly moving the starting end of the steel coil along the galvanizing tank 202 until it reaches the lowest point within the tank. The worker then inserts the starting end of the steel coil through the gap in conveyor roller B2021 on the other side of the galvanizing tank 202. Servo cylinder C2031 extends, causing connecting plate 203 to move downwards and engage at the opening above the galvanizing tank 202. The worker then secures connecting plate 203 to the opening of the galvanizing tank 202 using fixing bolts. Servo cylinders D205 and C2031 extend simultaneously.The galvanizing tank 202 is pushed down into the zinc bath 2, and the lowest point of the galvanizing tank 202 is immersed in the zinc bath. The zinc bath 202 enters the galvanizing tank 202 through the through groove at the bottom of the galvanizing tank 202, and galvanizes the lower surface of the steel strip. The zinc pump 201 operates, guiding the zinc bath 202 into the guide funnel 2032 through the zinc bath delivery pipe, and then into the cavity of the nozzle 2033 through the cavity, and then sprayed onto the upper surface of the steel strip from the nozzle 2033. On the upper surface of the steel strip, galvanizing is performed. A cooling fan 204 operates, blowing cold air through outlet 2041 onto the steel strip surface, causing the molten zinc to quickly solidify and dry. Finally, motor D2022 continues to operate, driving conveyor roller B2021 to rotate, clamping the steel strip and moving it slowly, ensuring the steel strip is evenly coated with molten zinc. Guide roller B2034 reduces the friction between the steel strip and connecting plate 203, making the steel strip move more smoothly. This process is repeated to perform pickling and galvanizing on the entire steel strip.
