Technical Field
[0001] This utility model relates to the field of acid pickling technology, specifically to an automated chemical treatment and dosing device. Background Technology
[0002] Steel wire rope is a flexible load-bearing component made of multiple strands of high-strength steel wire twisted together. It features high strength, good wear resistance, and excellent elasticity. Its core structure typically consists of a rope core (fiber core or metal core) and outer strands, which are spirally wound to form a tight whole. Based on the direction of twist, it can be classified into interlaced twist, unidirectional twist, etc. Different weaving methods affect its torsional performance. During the production process, steel wire rope usually requires pickling to remove surface oxide scale, rust, and other impurities, ensuring the quality of subsequent processing.
[0003] For example, authorization announcement number CN211972462U discloses a steel wire rope pickling device, including a pickling tank with multiple passing rollers installed inside. The steel wire enters from the rope inlet on the left side of the pickling tank, passes through each passing roller sequentially, and exits from the rope outlet. The pickling tank also includes an upper brush and a lower brush. Heating mechanisms for heating the pickling solution are provided on both sides of the pickling tank. Each heating mechanism includes a heating water pipe, and the upper part of the heating water pipe is connected to a circulating water tank equipped with a heating device via a connecting pipe. A flow control valve is installed on the connecting pipe. The advantages of this invention are: a reasonable structure; the multiple passing rollers allow the steel wire to pass through the pickling tank, increasing the contact time with the pickling solution; and the brushes inside the pickling tank allow for brushing the steel wire rope, resulting in a better pickling effect.
[0004] However, the pickling device in the above technology is not equipped with an automatic dosing device, and the acid solution needs to be replenished manually. Since the pH value of the pickling solution will gradually decrease after long-term use, frequent manual dosing operations are not only inefficient, but also increase the complexity of production management. Therefore, the market urgently needs to develop an automated chemical treatment and dosing device to help people solve the existing problems. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4An embodiment of this utility model provides an automated chemical treatment and dosing device, comprising an acid pickling tank 1, a support platform 4 fixedly connected to the middle of the rear end of the acid pickling tank 1, an acid pickling concentrate storage tank 401 fixedly connected to the upper end of the support platform 4, a filling pipe 402 fixedly connected to the lower end of the front face of the acid pickling concentrate storage tank 401, a metering pump 403 fixedly installed on the filling pipe 402, and the lower end of the filling pipe 402 extending into the interior of the acid pickling tank 1; a pH value detection device 105 fixedly connected to the lower end of the middle of the front face of the support platform 4, a detection probe 106 fixedly connected to the rear end of the pH value detection device 105, and the detection probe 106 extending into the interior of the acid pickling tank 1; a drain pipe 5 and a water injection pipe 6 fixedly connected to the rear end face of the support platform 4 and on both sides of the support platform 4, respectively; a control valve 501 fixedly connected to the drain pipe 5; and a quantitative delivery pump 601 fixedly connected to the water injection pipe 6. A control device 404 is fixedly connected to the surface. The control device 404 is electrically connected to the pH value detection device 105, the metering pump 403, the control valve 501, and the quantitative transfer pump 601. When the steel wire rope enters the pickling tank 1 for pickling, the pH value detection device 105 monitors the pH value of the pickling solution in real time through the detection probe 106 and feeds the data back to the control device 404. When the pH value of the pickling solution is lower than the set threshold, the control device 404 starts the metering pump 403 to quantitatively and slowly replenish the concentrated acid solution in the pickling concentrate storage tank 401 into the pickling tank 1 through the injection pipe 402. When the pickling solution in the pickling tank 1 needs to be replaced, the waste liquid is discharged through the drain pipe 5 by opening the control valve 501. After the waste liquid is discharged, new water is injected through the water injection pipe 6 by the quantitative transfer pump 601. At the same time, the metering pump 403 injects concentrated acid solution into the pickling tank 1 to mix with water according to the ratio.
[0024] Please see Figure 1 and Figure 4 A first support plate 101 is fixedly connected to both sides of the upper end face of the pickling tank 1. Rotary connecting parts 102 are fixedly connected to both the front and rear ends of the upper end of the first support plate 101. A first guide roller 103 is rotatably connected between the two rotating connecting parts 102. A second guide roller 104 is rotatably connected to both sides of the middle part of the lower end inside the pickling tank 1. The wire rope passes through the upper end of the first guide roller 103 on one side of the upper end of the pickling tank 1 and enters the interior of the pickling tank 1 downwards. After passing through the lower ends of the two first guide rollers 103, it rises and then passes through the upper end of the first guide roller 103 on the other side of the upper end of the pickling tank 1 and exits.
[0025] Please see Figure 4A second support plate 2 is fixedly connected to both sides of the middle of the front end of the upper end of the pickling tank 1. A limit tube 201 is fixedly connected to the middle of the lower end of the two second support plates 2. A rotating shaft 202 is rotatably connected inside the limit tube 201. The lower end of the rotating shaft 202 extends into the interior of the pickling tank 1 and a plurality of stirring blades 203 are fixedly connected to the side end face. A drive device 3 is fixedly connected to the middle of the upper end of the two second support plates 2. A drive motor 301 is fixedly installed inside the drive device 3. The upper end of the rotating shaft 202 extends into the interior of the drive device 3 and is connected to the output shaft of the drive motor 301 through a coupling. The drive motor 301 drives the rotating shaft 202 to rotate, so that the rotating shaft 202 drives the stirring blades 203 to stir the pickling liquid inside the pickling tank 1.
[0026] Working principle: During use, the steel wire rope enters from the upper end of the first guide roller 103 on one side of the pickling tank 1, is guided by the second guide roller 104 inside the tank, and then exits from the first guide roller 103 on the other side, forming a continuous pickling path. The drive motor 301 drives the stirring plate 203 to continuously stir the pickling solution through the rotating shaft 202, ensuring uniform distribution of the solution. The pH value detection device 105 monitors the pH value of the pickling solution in real time through the detection probe 106. When the value is lower than the set threshold, the control device 404 automatically starts the metering pump 403 to quantitatively replenish the concentrated acid solution in the pickling concentrate storage tank 401 into the pickling tank 1 through the injection pipe 402; at the same time, the quantitative delivery pump 601 replenishes clean water through the water injection pipe 6 to maintain the solution ratio balance. When the pickling solution inside pickling tank 1 needs to be replaced, the waste liquid is discharged through drain pipe 5 by opening control valve 501. After the waste liquid is discharged, new water is injected through water injection pipe 6 by metering pump 601. At the same time, metering pump 403 injects concentrated acid solution into pickling tank 1 according to the ratio to mix with water, and stirring plate 203 continuously stirs and mixes evenly. The whole process requires no manual intervention, effectively improving the stability and production efficiency of the pickling process.
