Description

Technical Field

[0001] This invention relates to the field of strip steel pickling technology, specifically to a continuous automated strip steel pickling equipment and its usage method. Background Technology

[0002] With the rapid development of the steel industry, the requirements for steel quality are increasing. As an important component of steel products, the surface quality of strip steel directly affects the performance of subsequent processing and final products. Therefore, efficient and precise pickling of strip steel is particularly important. Continuous automated strip steel pickling equipment has emerged to meet this demand. However, existing strip steel pickling equipment cannot quickly adjust for use with strip steel of different thicknesses, and the pickling solution cannot be quickly scraped off, reducing the applicability of the pickling equipment.

[0003] The existing steel strip pickling equipment has the following drawbacks:

[0004] 1. Patent document CN118422214A discloses a strip steel pickling equipment, "comprising: an acid return shell fixedly connected to the right side surface of the strip steel pickling tank; a detachable closed top cover installed on the top outer surface of the strip steel pickling tank; and a strip steel conveying shell fixedly connected to the left side surface of the strip steel pickling tank; the top outer surface of the acid return shell is provided with an elastic squeezing scraping unit, the elastic squeezing scraping unit including a limiting plate, a sliding rod, and a semi-circular scraper. This invention allows the steel to be completely pickled from the strip steel pickling tank..." The other end moves out and overlaps the upper and lower surfaces of the steel with the semi-circular scraper. Then, the motor on the inner surface of the casing pulls the three pairs of tension anti-corrosion ropes, thereby bringing the semi-circular scraper closer to the middle. As the semi-circular scraper contracts, it squeezes the elastic strips on both sides of the semi-circular scraper and presses the squeezing soft strips on the inner wall of the elastic strips to the left and right sides of the steel. However, the existing strip steel pickling equipment cannot quickly adjust when using strip steel of different thicknesses, and the pickling solution cannot be quickly scraped off, reducing the applicability of the pickling equipment.

[0005] 2. Patent document CN109536980A discloses a strip steel pickling circulation device, "including a box, a conveyor rod, an acid spraying mechanism, a feeding mechanism, a drive mechanism, a collection mechanism, and a cleaning mechanism; multiple cleaning mechanisms are installed inside the box, multiple acid spraying mechanisms are installed at the top of the box, and a collection mechanism is installed inside the box. When the steel plate moves inside the box, one acid spraying mechanism sprays acid onto the surface of the steel plate, and one cleaning mechanism rotates to make the acid come into contact with the steel plate, removing the oxide film on the surface of the steel plate. The acid that has been used initially falls into the inside of a collection mechanism. At this time, the feeding mechanism inside the second acid spraying mechanism moves, drawing the acid from the inside of the collection mechanism back into the second acid spraying mechanism. The acid is then sprayed onto the surface of the steel plate again through the second acid spraying mechanism, and the cleaning mechanism cleans the steel plate again. The acid that has been used twice falls into the inside of another collection mechanism for reuse, effectively utilizing the acid." However, the existing strip steel pickling equipment cannot quickly cool down the pickling tank, reducing the stability of the pickling solution in the pickling tank and weakening the pickling effect.

[0006] 3. Patent document CN108580161B discloses a strip steel pickling and oiling equipment, "including a base on both sides, with a lifting cylinder fixed at the top of each base. The piston rod of the lifting cylinder faces downward, and a bearing assembly is connected to the lower end of the piston rod. A rotating shaft is installed in each bearing assembly on both sides, and an eccentric oiling roller is connected between the two rotating shafts. The eccentric oiling roller has a hollow cylindrical structure and is connected to the oil outlet of an oil tank through multiple oil delivery hoses. A notch is opened at the bottom of the eccentric oiling roller, and an oiling felt strip is installed in the notch, positioned above the strip steel. Its significant effect is that it can automatically control the oiling of the strip steel surface, save oil, and reduce uneven oil film thickness, which can be adaptively adjusted according to the required rust-preventive oil thickness for different specifications of strip steel." However, the pickling solution in existing strip steel pickling equipment cannot be cooled in time, which reduces the pickling quality of the strip steel.

[0007] 4. Patent document CN114717569B discloses a strip steel pickling and filtration device, "including a shell, a first belt, a second belt, a third belt, a fourth belt, and a fifth belt. A first drive motor is installed on one side of the shell, and a first drive wheel is installed at the output end of the first drive motor. Multiple transmission rollers are rotatably connected inside the shell, and a first driven wheel is installed at one end of each transmission roller. The multiple first driven wheels are connected by a second belt. The first drive wheel is connected by one of the first driven wheels on the first belt. Two negative pressure shafts are rotatably connected inside the shell. A second drive wheel is installed at the output end of the second drive motor. A connecting rod is slidably connected in a groove. A scraper is provided on the connecting rod, and one end of the scraper contacts the filter screen. Two collection grooves are installed on the front side of the shell. A partition is provided on the filter screen. A controller is installed on the shell. Four bases are installed on the bottom surface of the shell, effectively improving the working cleaning efficiency of the equipment." However, the existing strip steel pickling equipment cannot quickly dry the water stains on the surface of the strip steel after pickling, which increases the drying time and reduces the efficiency of the pickling equipment.

[0014] Preferably, the temperature control component includes a temperature sensor and a controller.

[0015] Preferably, the real-time temperature data in the pickling tank is transmitted to the processing module. The processing module compares the real-time temperature data in the pickling tank with the suitable temperature data in the pickling tank.

The cleaning head is located at one end of the No. 7 rod.

[0018] Preferably, the fan is located above the heating wire.

[0019] Preferably, the method of using the pickling equipment includes the following steps:

[0020] Step S1: After the strip steel passes through the pickling tank, excess pickling liquid is scraped off between the scraper block and the scraper head. When using strip steel of different thicknesses, the electric push rod moves so that one end moves out of the No. 1 slot. At this time, the No. 1 motor rotates and drives the gear to move. The gear moves and drives the rack to move. The rack moves and drives the scraper head to move. The scraper head moves and drives the slide cylinder to move. The slide cylinder moves and adjusts the height of the scraper head stably. After adjusting to the appropriate height, the electric push rod is inserted into the No. 1 slot to fix the scraper head. This realizes the function of quickly adjusting the pickling liquid when using strip steel of different thicknesses, thus improving the applicability of the pickling equipment.

[0021] Step S2: The water pump starts and draws water from tank number two into the arc-shaped cooling radiator through water pipe number one. At this time, the arc-shaped cooling radiator absorbs the temperature in the pickling tank, thus cooling it down. The water after absorbing the temperature is discharged into tank number two through water pipe number two. At this time, motor number three rotates, driving the collecting wheel to rotate. The rotation of the collecting wheel drives the pull rope to move. The movement of the pull rope drives the connecting rod to move. The movement of the connecting rod drives spring number three to move. The movement of spring number three causes the connecting rod to drive cylinder number three to move. The movement of cylinder number three causes the connecting rod to drive the conical water distributor to move. The movement of the conical water distributor disperses the water, allowing it to fall onto the semiconductor cooling block over a larger area for rapid cooling. This achieves the function of rapid cooling in the pickling tank, improving the stability of the pickling solution in the pickling tank, and enhancing the pickling effect.

[0022] Step S3: When the processing module detects a high temperature, it controls the cooling component to increase its power. After the heating component increases its power, the temperature sensor continuously monitors the real-time temperature data in the pickling tank until the processing module detects a low temperature or a suitable temperature. When the processing module detects a suitable temperature, it controls the cooling component to maintain its power. After the heating component maintains its power, the temperature sensor continues to monitor the real-time temperature data in the pickling tank until the processing module detects a low temperature or a high temperature. When the processing module detects a low temperature, it controls the cooling component to turn off. After the heating component turns off, the temperature sensor continues to monitor the real-time temperature data in the pickling tank until the processing module detects a high temperature or a suitable temperature. This achieves the function of timely cooling of the pickling solution to improve the pickling quality of the pickling equipment for strip steel.

[0023] Step S4: The fan rotates and generates suction to draw air into box number five through the air inlet. At this time, the air is heated by the heating wire and then blown onto the surface of the strip steel through the air outlet. At this time, the electric rod moves, which drives rod number six to move. The movement of rod number six drives the rotating shaft to rotate, which drives rod number seven to move. The movement of rod number seven drives the cleaning head to swing. The swinging of the cleaning head further cleans the water stains on the surface of the strip steel, realizing the function of quickly drying the water stains on the surface of the strip steel after pickling, reducing the drying time and improving the efficiency of the pickling equipment.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention utilizes a scraper that removes excess pickling liquid from strip steel after it passes through an acid pickling tank. When using strip steel of different thicknesses, an electric push rod moves one end out of slot number one. At this time, a motor rotates, driving a gear to move. The gear moves, driving a rack to move. The rack moves, driving the scraper to move. The scraper moves, driving a slide cylinder to move. The slide cylinder moves, allowing the scraper to be adjusted to a stable height. After adjusting to the appropriate height, the electric push rod engages in slot number one to fix the scraper. This invention achieves the function of quickly adjusting the scraping liquid for strip steel of different thicknesses, thus improving the applicability of the acid pickling equipment.

[0026] 2. This invention uses a water pump to draw water from tank number two into an arc-shaped cooling radiator via pipe number one. The arc-shaped cooling radiator absorbs the temperature in the pickling tank, cooling it down. The cooled water is then discharged into tank number two via pipe number two. At this time, motor number three rotates, driving the collecting wheel to rotate. The rotating collecting wheel moves the pull rope, which in turn moves the connecting rod. The connecting rod moves the spring number three, which in turn moves the connecting rod and the cylinder number three. The cylinder number three moves the connecting rod and the conical water distributor head, which disperses the water, allowing it to fall onto the semiconductor cooling block over a larger area for rapid cooling. This achieves the functions of rapid cooling in the pickling tank, improving the stability of the pickling solution, and enhancing the pickling effect.

[0027] 3. This invention, through the installation of a processing module, detects a high temperature and controls the cooling component to increase its power. After the heating component increases its power, the temperature sensor continuously monitors the real-time temperature data in the pickling tank until the processing module detects a low or suitable temperature. When the processing module detects a suitable temperature, it controls the cooling component to maintain its power. After the heating component maintains its power, the temperature sensor continues to monitor the real-time temperature data in the pickling tank until the processing module detects a low or high temperature. When the processing module detects a low temperature, it controls the cooling component to shut down. After the heating component shuts down, the temperature sensor continues to monitor the real-time temperature data in the pickling tank until the processing module detects a high or suitable temperature. This achieves the function of timely cooling of the pickling solution and improving the pickling quality of the pickling equipment for steel strip.

[0028] 4. This invention utilizes a fan to generate suction, drawing air into chamber number five through the air inlet. The air is then heated by a heating wire and blown onto the strip surface through the air outlet. Simultaneously, the electric lever moves, causing lever number six to move, which in turn rotates the shaft, which in turn moves lever number seven. Lever number seven then causes the cleaning head to swing, further cleaning the water stains on the strip surface. This achieves rapid drying of water stains on the strip surface after pickling, reducing drying time and improving the efficiency of the pickling equipment. Attached Figure Description

If the real-time temperature data within the pickling tank 9 is greater than the suitable temperature data, the temperature is set to a high state. If the real-time temperature data within the pickling tank 9 is within the suitable temperature data, the temperature is set to a suitable state. If the real-time temperature data within the pickling tank 9 is less than the suitable temperature data, the temperature is set to a low state. The appropriate temperature data in the pickling tank 9 is set to a low temperature state. When the processing module detects a high temperature state, it controls the cooling component to increase its power. After the heating component increases its power, the temperature sensor 45 continuously monitors the real-time temperature data in the pickling tank 9 until the processing module detects a low temperature state or a suitable temperature state. When the processing module detects a suitable temperature state, it controls the cooling component to maintain its power. After the heating component maintains its power, the temperature sensor 45 continues to monitor the real-time temperature data in the pickling tank 9 until the processing module detects a low temperature state or a high temperature state. When the processing module detects a low temperature state, it controls the cooling component to shut down. After the heating component shuts down, the temperature sensor 45 continues to monitor the real-time temperature data in the pickling tank 9 until the processing module detects a high temperature state or a suitable temperature state. This achieves the function of timely cooling of the pickling solution and improving the pickling quality of the pickling equipment for strip steel.

[0044] Example 4: Please refer to Figure 2 and Figure 8One embodiment of the present invention provides a drying assembly comprising a fifth chamber 21, an air inlet 22, an air outlet 26, a heating wire 24, a fan 23, an electric rod 25, and a cleaning head 28. The fifth chamber 21 is located on the inner wall of the outer casing 1. The air inlet 22 is located at the top of the fifth chamber 21, and the air outlet 26 is located at the bottom of the fifth chamber 21. The heating wire 24 is located on the inner wall of the fifth chamber 21. The electric rod 25 is located on the inner wall of the fifth chamber 21. A sixth rod 29 is installed at the output end of the electric rod 25. A seventh rod 27 is installed on the inner wall of the air outlet 26 via a rotating shaft, and one end of the seventh rod 27 is connected to the outer wall of the sixth rod 29 via the rotating shaft. The cleaning head 28 is located on... At one end of rod 27, fan 23 is positioned above heating wire 24. Fan 23 rotates to generate suction, drawing air through air inlet 22 into box 21. The air is then heated by heating wire 24 and blown onto the strip surface through air outlet 26. At this time, electric rod 25 moves, driving rod 29 to move. The movement of rod 29 drives the rotating shaft to rotate, which in turn drives rod 27 to move. The movement of rod 27 causes cleaning head 28 to swing, further cleaning the water stains on the strip surface. This achieves the function of quickly drying the water stains on the strip surface after pickling, reducing drying time, and improving the efficiency of the pickling equipment.

[0045] The method of using this pickling equipment includes the following steps:

[0046] Step S1: After the strip steel passes through the pickling tank 9, excess pickling liquid is scraped off between the scraper block and the scraper head 16. When using strip steel of different thicknesses, the electric push rod 19 moves so that one end moves out of the first slot 18. At this time, the first motor 12 rotates and drives the gear 13 to move. The gear 13 moves and drives the rack 20 to move. The rack 20 moves and drives the scraper head 16 to move. The scraper head 16 moves and drives the slide cylinder 15 to move. The slide cylinder 15 moves and allows the scraper head 16 to be stably adjusted in height. After adjusting to the appropriate height, the electric push rod 19 is inserted into the first slot 18 to fix the scraper head 16. This realizes the function of quickly adjusting the pickling liquid when using strip steel of different thicknesses, thus improving the applicability of the pickling equipment.

[0047] Step S2: Water pump 31 starts and draws water from tank 2 30 into arc-shaped cooling radiator 33 through water pipe 1 32. At this time, arc-shaped cooling radiator 33 absorbs the temperature in pickling tank 9 to cool it down. The water after absorbing the temperature is discharged into tank 2 30 through water pipe 2 34. At this time, motor 3 42 rotates and drives collecting wheel 43 to rotate. The rotation of collecting wheel 43 drives pull rope 44 to move. The movement of pull rope 44 drives connecting rod 50 to move. The movement of connecting rod 50 drives spring 3 40 to move. The movement of spring 3 40 causes connecting rod 50 to drive cylinder 39 to move. The movement of cylinder 39 causes connecting rod 50 to drive conical water distributor 36 to move. The movement of conical water distributor 36 disperses the water and makes it fall onto semiconductor cooling block 35 over a larger area for rapid cooling. This achieves the function of rapid cooling in pickling tank 9, improving the stability of pickling solution in pickling tank 9 and enhancing pickling effect.

[0048] Step S3: When the processing module detects a high temperature, it controls the cooling component to increase its power. After the heating component increases its power, the temperature sensor 45 continuously monitors the real-time temperature data in the pickling tank 9 until the processing module detects a low temperature or a suitable temperature. When the processing module detects a suitable temperature, it controls the cooling component to maintain its power. After the heating component maintains its power, the temperature sensor 45 continues to monitor the real-time temperature data in the pickling tank 9 until the processing module detects a low temperature or a high temperature. When the processing module detects a low temperature, it controls the cooling component to turn off. After the heating component turns off, the temperature sensor 45 continues to monitor the real-time temperature data in the pickling tank 9 until the processing module detects a high temperature or a suitable temperature. This achieves the function of timely cooling of the pickling solution to improve the pickling quality of the pickling equipment for strip steel.

[0049] Step S4: The fan 23 rotates to generate suction, drawing air through the air inlet 22 into the fifth chamber 21. At this time, the air is heated by the heating wire 24. After heating, the air is blown onto the strip surface through the air outlet 26. At this time, the electric rod 25 moves, driving the sixth rod 29 to move. The movement of the sixth rod 29 drives the rotating shaft to rotate, which in turn drives the seventh rod 27 to move. The movement of the seventh rod 27 causes the cleaning head 28 to swing. The swinging of the cleaning head 28 further cleans the water stains on the strip surface, realizing the function of quickly drying the water stains on the strip surface after pickling, reducing drying time, and improving the efficiency of the pickling equipment.

[0050] Working principle: After the strip steel passes through the pickling tank 9, excess pickling solution is scraped off between the scraper block and the scraper head 16. When using strip steel of different thicknesses, the electric push rod 19 moves so that one end moves out of the first slot 18. At this time, the first motor 12 rotates, driving the gear 13 to move. The movement of the gear 13 drives the rack 20 to move, which in turn drives the scraper head 16 to move. The movement of the scraper head 16 drives the slide cylinder 15 to move, allowing the scraper head 16 to be stably adjusted in height. After adjusting to the appropriate height, the electric push rod 19 is inserted into the first slot 18 to fix the scraper head 16. This achieves the function of quickly adjusting the pickling solution and quickly scraping off the pickling solution when using strip steel of different thicknesses, thus improving the applicability of the pickling equipment. The water pump 31 starts and pumps water from the second tank 30 through the first water pump. Pipe 32 draws water into the arc-shaped cooling radiator 33, which then adsorbs the heat from the pickling tank 9, cooling it down. The cooled water is then discharged into the second tank 30 via pipe 34. Simultaneously, motor 42 rotates, driving the collecting wheel 43 to rotate. This rotation moves the pull rope 44, which in turn moves the connecting rod 50. The connecting rod 50 then moves the third spring 40, which in turn moves the connecting rod 50, which in turn moves the third cylinder 39. The third cylinder 39 then moves the connecting rod 50, which in turn moves the conical water distributor 36. The conical water distributor 36 disperses the water, allowing it to fall onto the semiconductor cooling block 35 over a larger area for rapid cooling. This achieves rapid cooling and improved temperature control within the pickling tank 9. The pickling tank 9 enhances the stability of the pickling solution and improves the pickling effect. When the processing module detects a high temperature, it controls the cooling component to increase its power. After the heating component increases its power, the temperature sensor 45 continuously monitors the real-time temperature data in the pickling tank 9 until the processing module detects a low or suitable temperature. When the processing module detects a suitable temperature, it controls the cooling component to maintain its power. After the heating component maintains its power, the temperature sensor 45 continues to monitor the real-time temperature data in the pickling tank 9 until the processing module detects a low or high temperature. When the processing module detects a low temperature, it controls the cooling component to shut down. After the heating component shuts down, the temperature sensor 45 continues to monitor the temperature data in the pickling tank 9. Real-time temperature data is collected until the processing module detects a high or suitable temperature, enabling timely cooling of the pickling solution and improving the pickling quality of the strip steel. The fan 23 rotates to generate suction, drawing air through the air inlet 22 into the fifth chamber 21. The air is then heated by the heating wire 24 and blown onto the strip steel surface through the air outlet 26. At this time, the electric rod 25 moves, driving the sixth rod 29 to move. The movement of the sixth rod 29 drives the rotating shaft to rotate, which in turn drives the seventh rod 27 to move. The movement of the seventh rod 27 causes the cleaning head 28 to swing, further cleaning the water stains on the strip steel surface. This achieves rapid drying of water stains on the strip steel surface after pickling, reducing drying time and improving the efficiency of the pickling equipment.
