A stainless steel cold reduction pickling treatment apparatus

Abstract

This invention provides a stainless steel cold annealing and pickling treatment equipment, relating to the field of stainless steel pickling technology. It includes a processing table; a pickling tank is fixedly installed at the left end of the processing table, and a through-hole discharge pipe is installed at the lower left end of the pickling tank. By placing the stainless steel workpiece to be pickled into a cylindrical pickling cage, the pickling cage descends and immerses in the pickling tank. When fully submerged, a trigger rod touches a trigger-type alarm and emits a warning sound, facilitating accurate timing by the operator. During pickling, a fluororubber rod rotates and rises with a threaded rod, continuously agitating the workpiece to ensure it is fully turned over within the cage, eliminating pickling dead zones. This solves the problem that the oxide scale on the surface of stainless steel workpieces is dense and has strong adhesion, thus requiring automatic pickling and mechanical turning. Otherwise, relying solely on static immersion results in insufficient contact between the workpiece and the pickling solution, especially at the bottom or adjacent parts of the workpiece, making effective acid wetting difficult, leading to uneven oxide scale removal and severe localized residue.

Description

Technical Field

[0001] This invention relates to the field of stainless steel pickling technology, and in particular to a stainless steel cold annealing and pickling equipment. Background Technology

[0002] During the production and processing of stainless steel strip or sheet, a dense oxide scale (commonly known as black scale) forms on the surface of the material after the cold rolling process, while the material itself undergoes hardening due to cold working. To restore the corrosion resistance, surface finish, and plasticity of stainless steel to meet subsequent processing and usage requirements, a combined annealing and pickling treatment, known as cold annealing and pickling, is necessary. Currently, commonly used cold annealing and pickling equipment typically includes, in sequence, an annealing furnace, a cooling section, a scale remover, a shot blasting machine, a multi-stage pickling tank (using a mixed acid solution such as sulfuric acid, nitric acid, and hydrofluoric acid), a final cleaning section, and a drying device. However, existing equipment has many shortcomings in actual operation: First, the cooling section after annealing mostly uses water cooling or air cooling, which has limited cooling efficiency and insufficient temperature control, easily leading to uneven surface temperature of the strip steel and thus affecting the uniformity of subsequent pickling; Second, the dust and debris generated by the descaling and shot blasting processes are not thoroughly cleaned, and residual particles will enter the pickling tank with the strip steel, not only contaminating the acid solution and accelerating acid loss, but also potentially forming indentations or scratches on the surface of the strip steel; Third, multi-stage pickling tanks are usually only isolated by simple squeeze rollers, resulting in serious acid cross-contamination, which wastes chemical agents and increases the burden of waste liquid treatment; In addition, the cleaning section after pickling often uses single-stage spray rinsing, which uses a large amount of water and has limited cleaning effect, and acid ions are easily left on the surface of the strip steel, leading to pitting or yellowing problems during later storage or use.

[0003] During the use of the processing equipment, due to the dense structure and strong adhesion of the oxide scale on the surface of stainless steel workpieces, it is necessary to automatically pickle the workpieces and mechanically turn them over. Otherwise, relying solely on static immersion, the contact between the workpiece and the pickling solution is insufficient, especially the bottom of the workpiece or the parts that are in contact with each other, which are difficult to be effectively wetted by the acid solution, resulting in uneven removal of oxide scale and serious local residue. Summary of the Invention

[0004] This invention relates to a stainless steel cold annealing and pickling equipment. The stainless steel workpiece to be pickled is placed in a cylindrical pickling cage, which descends and immerses in the pickling tank. When fully submerged, a trigger rod activates a trigger alarm, emitting an audible alert for precise timing by the operator. During pickling, a fluororubber rod rotates and rises with a threaded rod, continuously agitating the workpiece to ensure it is fully rotated within the cage, eliminating pickling dead zones and ensuring uniform contact between all surfaces of the workpiece and the acid solution. This improves the oxide scale removal effect and pickling quality. Simultaneously, an industrial camera captures real-time image information of the pickling process and transmits it to a display screen on the upper part of the fixed frame. The operator can visually monitor the pickling status of the workpiece through the display screen, promptly detect pickling abnormalities, and adjust process parameters without opening the pickling tank for observation. This ensures operator safety and improves the controllability of the pickling process.

[0005] In a first aspect, the present invention provides a stainless steel cold annealing and pickling treatment device, specifically comprising: a processing table; an pickling tank fixedly installed at the left end of the processing table, and a through discharge pipe installed at the lower end of the left end of the pickling tank; a fixing frame fixedly installed at the left rear end of the processing table; an extension plate fixedly installed on the front side of the upper end of the fixing frame, and through circular holes respectively opened at both ends of the extension plate; and a through rod hole opened in the middle of the extension plate. A fixed frame is fixedly installed at the right end of the extension plate, and a through shaft hole is opened in the middle of the fixed frame; through synchronous electric rods are fixedly installed at the round holes at both ends of the extension plate, and connecting plates are fixedly installed at the telescopic ends of the synchronous electric rods; through guide rods are fixedly installed at both ends of the two connecting plates, and trigger rods are fixedly installed at the upper ends of the two rear guide rods; a cylindrical pickling cage is fixedly installed at the lower ends of the four guide rods, and through round holes are evenly opened on the pickling cage. A cleaning tank is fixedly installed at the right end of the processing table, and a sealing door is installed at the rear end of the cleaning tank. A fixing plate is fixedly installed at the middle of the upper end of the cleaning tank, and a track hole is opened at the left end of the fixing plate. An electric push rod is fixedly installed at the right end of the fixing plate, and a connecting block is fixedly installed at the telescopic end of the electric push rod. A track block is fixedly installed at the bottom of the connecting block, and elastic rods are evenly installed at the lower end of the track block.

[0006] Furthermore, two diagonal bracing plates are fixedly installed on the inner side wall of the fixing frame, a display screen is fixedly installed at the upper end of the fixing frame, and symmetrical side strips are fixedly installed at the lower end of the display screen, with through bolts inserted at both ends of the side strips.

[0007] Furthermore, a trigger-type alarm is fixedly installed at the rear end of the extension plate, through guide holes are opened at the four corners of the extension plate, and a through industrial camera is fixedly installed at the bottom of the extension plate.

[0008] Furthermore, an annular groove is provided at the upper edge of the extension plate rod hole, a rotating toothed threaded cylinder is installed at the upper end of the extension plate rod hole, a threaded hole is provided in the middle of the toothed threaded cylinder, and a rotating ring is fixedly installed at the bottom of the toothed threaded cylinder.

[0009] Furthermore, a through threaded rod is rotatably inserted into the threaded hole of the toothed threaded cylinder, and a fixed cylinder is fixedly installed at the lower end of the threaded rod.

[0010] Furthermore, a fluororubber rod is fixedly installed on the annular sidewall of the fixed cylinder, and a limit plate is fixedly installed at the bottom of the fixed cylinder.

[0011] Furthermore, symmetrical side plates are fixedly installed at the lower end of the fixed frame, and through bolts are inserted at both ends of the side plates. A through reciprocating motor is fixedly installed at the upper end of the shaft hole in the middle of the fixed frame, and a toothed disc is fixedly installed on the shaft of the reciprocating motor.

[0012] This invention provides a stainless steel cold annealing and pickling treatment equipment, which has the following beneficial effects: In this invention, the stainless steel workpiece to be pickled is placed in a cylindrical pickling cage during use. The cage descends and immerses in the pickling tank. When fully submerged, the trigger rod touches the trigger-type alarm and emits a warning sound, facilitating accurate timing for the operator. During pickling, the fluororubber rod rotates and rises with the threaded rod, continuously agitating the workpiece to ensure it is fully turned over within the cage, eliminating pickling dead zones and ensuring uniform contact between all surfaces of the workpiece and the acid solution. This improves the oxide scale removal effect and pickling quality. Simultaneously, an industrial camera collects image information of the pickling process in real time and transmits it to a display screen on the upper end of the fixed frame. The operator can visually monitor the pickling status of the workpiece through the display screen, promptly detect pickling abnormalities, and adjust process parameters without opening the pickling tank for observation. This ensures operator safety and improves the controllability of the pickling process.

[0013] In addition, the two sets of synchronous electric rods on the extension plate are activated. The telescopic ends of the synchronous electric rods extend downwards, driving the connecting plate and guide rods to move downwards synchronously. The upper ends of the two guide rods at the rear end are respectively fixed with trigger rods. When the guide rods move downwards to the set position, the trigger rods immediately touch the trigger-type alarm and emit a warning sound. At this time, the pickling cage is completely immersed in the pickling tank, realizing precise positioning and pickling of stainless steel workpieces. This effectively avoids pickling quality fluctuations and equipment damage caused by insufficient or excessive immersion depth. During the pickling process of stainless steel workpieces, the industrial camera at the bottom of the extension plate captures the pickling status in real time. The image and equipment operating parameters are synchronously transmitted to the display screen at the top of the fixed frame. Operators can monitor the pickling process, workpiece status and equipment operation in real time, grasp the processing progress in a timely manner and respond quickly to abnormal situations, greatly improving the controllability, safety and standardization of the pickling process.

[0014] In addition, the reciprocating motor on the fixed frame is started, and the reciprocating motor shaft drives the sawtooth disk to rotate continuously. The sawtooth disk meshes with the outer tooth groove of the toothed threaded cylinder, driving the toothed threaded cylinder to rotate horizontally and stably in the ring groove through the rotating ring. When the toothed threaded cylinder rotates, the central threaded hole cooperates with the threaded rod, causing the threaded rod to drive the fixed cylinder and the fluororubber rod to rotate synchronously and make up-and-down reciprocating motions. The fluororubber rod rotates downward or upward accordingly, frequently and flexibly agitating the stainless steel workpieces in the pickling cage, so that the workpieces are constantly turned and repositioned in the pickling solution, eliminating pickling dead corners, ensuring that the workpiece surface is in uniform and sufficient contact with the acid solution, improving pickling quality and processing efficiency. After the preset pickling time is reached, the reciprocating motor drives the fluororubber rod to move upward and reset, avoiding the fluororubber rod interfering with the lifting and discharge of the workpiece, ensuring continuous and stable operation of the equipment.

[0015] By transferring the pickled stainless steel workpiece into the cleaning tank, the electric push rod on the fixed plate is activated. The telescopic end of the electric push rod reciprocates, driving the connecting block and the track block to slide stably left and right along the track holes of the fixed plate. The elastic rod at the lower end of the track block moves left and right simultaneously, performing a gentle brushing on the surface of the workpiece. Combined with the cleaning solution in the cleaning tank, this thoroughly removes residual acid, oxide scale, and impurities from the surface of the workpiece, preventing residual acid from corroding the workpiece surface and causing quality defects such as pitting and yellowing. This effectively improves the surface smoothness and corrosion resistance of the stainless steel workpiece. After cleaning, the electric push rod stops running, and the treated stainless steel workpiece can be removed by opening the sealed door, completing an automated, efficient, and high-quality stainless steel cold annealing pickling and cleaning process.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1 to 9 : This invention proposes a stainless steel cold annealing and pickling treatment equipment, comprising: a processing table 1; a pickling tank 2 fixedly installed at the left end of the processing table 1, and a through discharge pipe installed at the lower end of the left end of the pickling tank 2; a fixing frame 3 fixedly installed at the left rear end of the processing table 1; an extension plate 4 fixedly installed on the front side of the upper end of the fixing frame 3, and through circular holes respectively opened at both ends of the extension plate 4; a through rod hole opened in the middle of the extension plate 4; a fixing frame 5 fixedly installed at the right end of the extension plate 4, and a through shaft hole opened in the middle of the fixing frame 5; and through synchronous electric rods 6 fixedly installed at the circular holes at both ends of the extension plate 4, the telescopic ends of the synchronous electric rods 6 retracting upwards. The synchronous electric rod 602 and pickling cage 604 are simultaneously lifted upwards, causing the pickling cage 604 and the internal workpieces to detach from the pickling solution in the pickling tank 2. The trigger rod 603 then moves upwards and separates from the trigger alarm 401, automatically deactivating the alarm signal. The pickling cage 604 remains at its initial high position, completing the pickling process. A connecting plate 601 is fixedly installed at the telescopic end of the synchronous electric rod 6. Guide rods 602 are fixedly installed at both ends of the two connecting plates 601. When the two sets of synchronous electric rods 6 on the extension plate 4 are activated, the telescopic ends of the synchronous electric rods 6 extend downwards, causing the connecting plates 601 and guide rods 602 to move downwards synchronously. The guide rods 602 extend along the... The guide hole 402 of the extension plate 4 slides vertically, strictly limiting the movement trajectory of the pickling cage 604 to prevent deviation, tilting, or shaking during lifting. Trigger rods 603 are fixedly installed at the upper ends of the two rear guide rods 602. When the guide rods 602 move downwards, the trigger rods 603 will touch the trigger alarm 401, which will then sound an alarm. At this time, the pickling cage 604 will fully enter the pickling tank 2 to pickle the stainless steel workpieces within. A cylindrical pickling cage 604 is fixedly installed at the lower ends of the four guide rods 602, and the pickling cage 604 has evenly spaced through-holes. The stainless steel to be pickled is placed in the pickling cage 604. When the guide rod 602 drives the pickling cage 604 to be completely immersed in the pickling solution in the pickling tank 2, the trigger rod 603 at the upper end of the rear guide rod 602 touches the trigger alarm 401. The trigger alarm 401 immediately emits an audible and visual alarm signal to indicate that the pickling cage 604 has reached the pickling station. The synchronous electric rod 6 automatically stops its downward movement, keeping the pickling cage 604 stably immersed in the pickling solution. A cleaning tank 7 is fixedly installed on the right end of the processing table 1. A sealing door is installed at the rear end of the cleaning tank 7. By opening the sealing door at the rear end of the cleaning tank 7, the sewage in the cleaning tank 7 can be discharged and the debris can be cleaned.

[0021] Two diagonal bracing plates 301 are fixedly installed on the inner side wall of the fixing frame 3. The display screen 302 is fixedly installed on the upper end of the fixing frame 3. Symmetrical side strips are fixedly installed on the lower end of the display screen 302. Through bolts are inserted at both ends of the side strips. The bolts on the side strips of the display screen 302 are rotated and inserted into the fixing frame 3 to fix and restrict the display screen 302. The display screen 302 will not move when touched.

[0022] The extension plate 4 has a trigger-type alarm 401 fixedly installed at its rear end. Through guide holes 402 are provided at each of the four corners of the extension plate 4. A through industrial camera 403 is fixedly installed at the bottom of the extension plate 4. During the pickling process of the stainless steel workpiece, the industrial camera 403 at the bottom of the extension plate 4 captures the pickling status in real time, and the image and equipment operating parameters are synchronously transmitted to the display screen 302 on the upper end of the mounting bracket 3. Operators can monitor the pickling process in real time. A rotating groove 404 is provided at the upper edge of the rod hole of the extension plate 4. A rotating toothed threaded cylinder 405 is installed at the upper end of the rod hole of the extension plate 4, and a threaded hole is provided in the middle of the toothed threaded cylinder 405. A rotating ring 406 is fixedly installed at the bottom of the toothed threaded cylinder 405, and the rotating ring 406 is rotatably installed in the rotating groove 404. The rotating ring 406 rotates horizontally without shifting during the rotation. A threaded rod 407 is rotatably inserted into the threaded hole of the toothed threaded cylinder 405, and a fixed cylinder 408 is fixedly installed at the lower end of the threaded rod 407. A fluororubber rod 409 is fixedly installed on the annular side wall of the fixed cylinder 408. When the reciprocating motor 502 on the fixed frame 5 is started, the shaft of the reciprocating motor 502 drives the sawtooth disk 503 to rotate continuously. The sawtooth disk 503 meshes with the outer tooth groove of the toothed threaded cylinder 405, driving the toothed threaded cylinder 405 to rotate horizontally and stably within the annular groove 404 through the rotating ring 406. When the toothed threaded cylinder 405 rotates, the central threaded hole cooperates with the threaded rod 407, causing the threaded rod 407 to drive the fixed cylinder 408 and the fluororubber rod 409 to rotate synchronously and perform up-and-down reciprocating motion.The fluororubber rod 409 moves downwards and rotates or upwards and rotates, frequently and flexibly agitating the stainless steel workpieces inside the pickling cage 604. This causes the workpieces to continuously tumble and reposition in the pickling solution, eliminating pickling dead zones and ensuring uniform and sufficient contact between the workpiece surface and the acid solution, thus improving pickling quality and efficiency. After the preset pickling time is reached, the reciprocating motor 502 drives the fluororubber rod 409 upwards. A limit plate 410 is fixedly installed at the bottom of the fixed cylinder 408. Symmetrical side plates 501 are fixedly installed at the lower end of the fixed frame 5, and through bolts are inserted at both ends of the side plates 501. The bolts on the side plates 501 are rotated and inserted into the extension plate 4 to fix and restrict the side plates 501 and the fixed frame 5. The fixed frame 5 will not shift when touched. The upper end of the shaft hole in the middle of the fixed frame 5 is fixed. A reciprocating motor 502 is installed, and a toothed disc 503 is fixedly mounted on the shaft of the reciprocating motor 502. The teeth on the toothed disc 503 mesh with the tooth grooves on the outer wall of the toothed threaded cylinder 405. During the pickling process, when the stainless steel workpiece in the pickling cage 604 is started, the toothed disc 503 on the shaft of the reciprocating motor 502 will rotate, simultaneously driving the toothed threaded cylinder 405 to rotate horizontally. At this time, the threaded rod 407 and the fixed cylinder 408 in the middle of the toothed threaded cylinder 405 will rotate and move up and down. The fluororubber rod 409 on the fixed cylinder 408 will frequently agitate the stainless steel workpiece in the pickling cage 604. Since the stainless steel workpiece is relatively light in the pickling solution, the fluororubber rod 409 can easily agitate the stainless steel workpiece in the pickling solution, causing the stainless steel workpiece to tumble and be thoroughly pickled in the pickling cage 604.

[0023] A fixing plate 701 is fixedly installed in the middle of the upper part of the cleaning tank 7. A track hole 702 is opened at the left end of the fixing plate 701, and an electric push rod 703 is fixedly installed at the right end of the fixing plate 701. A connecting block 704 is fixedly installed at the telescopic end of the electric push rod 703, and a track block 705 is fixedly installed at the bottom of the connecting block 704. When the pickled stainless steel workpiece is transferred into the cleaning tank 7, the electric push rod 703 on the fixing plate 701 is activated. The telescopic end of the electric push rod 703 reciprocates, driving the connecting block 705. Block 704 and track block 705 slide stably left and right along the track hole 702 of the fixed plate 701. The elastic rod 706 at the lower end of track block 705 moves left and right synchronously to perform a gentle brushing on the surface of the workpiece. With the help of the cleaning solution in the cleaning tank 7, the residual acid, oxide scale and impurities on the surface of the workpiece are thoroughly removed. After cleaning, the electric push rod 703 stops running and the treated stainless steel workpiece is taken out, completing a complete stainless steel cold annealing pickling and cleaning process. The elastic rods 706 are evenly installed at the lower end of track block 705.

[0024] Example 2, based on Example 1, such as Figure 1 and Figure 9As shown, the lower end of the fixed frame 5 is fixedly installed with symmetrical side plates 501, and the two ends of the side plates 501 are respectively inserted with through bolts. After removing the side plates 501 and bolts, the fixed frame 5 is fixedly welded to the extension plate 4 to stabilize and restrict the fixed frame 5. In this way, the fixed frame 5 will not tilt when touched, avoiding the bolts from loosening after long-term use and failing to stabilize the fixed frame 5, while also saving on component costs.

[0025] Working Principle: In operation, the operator first places the stainless steel workpiece to be pickled into the cylindrical pickling cage 604. The synchronous electric lever 6 is then activated, its telescopic end driving the connecting plate 601 to move vertically downwards. The connecting plate 601, through four guide rods 602, drives the pickling cage 604 to descend synchronously into the pickling tank 2. During this process, the guide rods 602 slide through the guide holes 402 at the four corners of the extension plate 4, precisely limiting the lifting path of the pickling cage 604, effectively preventing it from shifting or tilting during vertical movement, ensuring the workpiece is smoothly immersed in the pickling solution. When the pickling cage 604 is completely submerged in the pickling solution, the trigger rods 603 at the upper ends of the two rear guide rods 602 precisely touch the trigger-type alarm 401 at the rear end of the extension plate 4, triggering the alarm. The alarm 401 sounds to indicate that the workpiece has entered the pickling stage, allowing the operator to start timing. During pickling, the reciprocating motor 502 on the upper part of the fixed frame 5 is started, and the sawtooth disk 503 on its shaft rotates accordingly. Since the sawtooth disk 503 meshes with the tooth grooves on the outer wall of the toothed threaded cylinder 405, it drives the toothed threaded cylinder 405 to rotate horizontally within the annular groove 404. A rotating ring 406 is fixedly installed at the bottom of the toothed threaded cylinder 405, and the rotating ring 406 is rotatably installed in the annular groove 404 to ensure that the toothed threaded cylinder 405 rotates smoothly without deviation. A threaded hole is opened in the middle of the toothed threaded cylinder 405, and the threaded rod 407 is rotatably inserted into the threaded hole. When the toothed threaded cylinder 405 rotates, the threaded rod 407 rotates accordingly. The threaded rod 407 rotates and moves vertically up and down. A fixed cylinder 408 is fixedly installed at the lower end of the threaded rod 407. A fluororubber rod 409 is fixedly installed on the annular side wall of the fixed cylinder 408. As the threaded rod 407 moves up and down, the fluororubber rod 409 frequently agitates the stainless steel workpiece inside the pickling cage 604. Due to the large buoyancy of the stainless steel workpiece in the pickling solution, it is relatively lightweight. The fluororubber rod 409 can easily agitate the workpiece, causing it to continuously tumble within the pickling cage 604. This ensures that all surfaces of the workpiece can fully and evenly contact the pickling solution, significantly improving the pickling effect. Simultaneously, an industrial camera 403 at the bottom of the extension plate 4 collects image information during the pickling process in real time and transmits it to the display screen 302 at the top of the fixed frame 3. The display screen 302 allows operators to visually monitor the pickling status of the workpiece and the equipment operation, facilitating timely adjustments to process parameters or handling of abnormal situations. After pickling is completed, the synchronous electric rod 6 reverses direction, and the telescopic end retracts upwards. The pickling cage 604 is vertically lifted from the pickling tank 2 via the connecting plate 601 and guide rod 602. Once the pickling cage 604 reaches the preset height, the lifting action stops. At this point, the pickling cage 604 is positioned above the cleaning tank 7. Simultaneously, the trigger rod 603 moves away from the trigger alarm 401, turning it off. Then, the reciprocating motor 502 lifts the fixed cylinder 408 and the fluororubber rod 409 upwards. Finally, the stainless steel workpiece in the pickling cage 604 is placed into the cleaning tank 7.The electric push rod 703 at the top of the cleaning tank 7 is activated. Its telescopic end drives the connecting block 704 to move horizontally. The track block 705 at the bottom of the connecting block 704 slides horizontally along the track hole 702 at the left end of the fixed plate 701. Several elastic rods 706 are evenly installed at the lower end of the track block 705. The elastic rods 706 move horizontally back and forth with the track block 705, elastically agitating and cleaning the pickled stainless steel workpieces, effectively removing residual acid and attached impurities from the workpiece surface. The track hole 702 limits the sliding path of the track block 705, ensuring that the elastic rods 706 move smoothly and without deviation during the cleaning process, ensuring uniform and reliable cleaning. After cleaning, the operator removes the stainless steel workpiece from the cleaning tank 7, and it can proceed to the next process or undergo finished product inspection.
