Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stainless steel wire rod production, and specifically relates to a pickling device for hot-rolled stainless steel wire rod. Background Art
[0002] The pickling of stainless steel wire rod is an important surface treatment process, aiming to remove the oxide layer, dirt and other surface defects on its surface to improve its surface quality and corrosion resistance.
[0003] After retrieval, a patent with the patent publication number CN204625794U discloses a pickling device. Although the device can support the whole pickling device by setting rollers when in use, and the pickling device can be conveniently moved on the ground through the rollers. However, when the device is in use, the stainless steel wire rod is directly immersed in the pickling solution without auxiliary pickling equipment and means. The position of the stainless steel wire rod in the pickling solution is relatively fixed, and the stainless steel wire rod needs a longer static soaking time to achieve the expected pickling effect. This not only increases the pickling cycle, but also may cause excessive corrosion of the stainless steel surface due to the too long soaking time. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a pickling device for hot-rolled stainless steel wire rod, which solves the problems put forward in the background art.
[0005] The solution of the utility model to the above technical problems is as follows:
[0006] A pickling device for hot-rolled stainless steel wire rod includes a base, a box body is installed on the base, and a conduit is penetrated and opened on one side of the box body;
[0007] A circulation pump is installed inside the base, the box body is provided with a containing cavity, and the containing cavity is communicated with a pickling solution container through the circulation pump. The side wall and the bottom of the box body are provided with containing grooves, and a heating resistance belt is installed in the containing grooves;
[0008] A fixed seat is arranged above the box body through a cantilever, a fixed shaft is inserted into the fixed seat, an ultrasonic probe is installed at the end of the fixed shaft, and a stirring module is installed at the bottom end of the box body.
[0009] On the basis of the above technical solution, the utility model can be further improved as follows.
[0010] Further, the base is provided with a bottom plate, and the cantilever and the circulation pump are installed on the bottom plate of the base.
[0011] The beneficial effect of adopting the above further scheme is:
[0012] The bottom plate, as the basic part of the base, provides a stable support platform for key components such as the cantilever and the circulation pump. This design enhances the structural rigidity of the entire pickling device, making it more stable and reliable during operation, and reducing the risk of equipment shaking or damage caused by vibration or external forces.
[0013] Furthermore, a top cover is installed on the box body, and a clamping plate is installed inside the box body. The stirring module is installed and limited in the box body through the clamping plate.
[0014] The beneficial effects of adopting the above further scheme are:
[0015] The design of the top cover can effectively seal the upper opening of the box body, preventing the pickling solution from splashing out of the box body due to stirring or ultrasonic action during the pickling process, ensuring the full utilization of the pickling solution, and at the same time avoiding environmental pollution and harm to operators caused by the pickling solution. The good sealing performance can reduce the air exchange inside and outside the box body, which helps to maintain the stability of parameters such as the concentration, temperature, and humidity of the pickling solution inside the box body, and ensures the consistency and controllability of the pickling process. The clamping plate, as a supporting and limiting device for the stirring module, can ensure the stable position and posture of the stirring module in the box body. This stable support structure can reduce the vibration and displacement generated by the stirring module during operation, and reduce its impact on the box body and other components.
[0016] Furthermore, the stirring module is provided with a motor, a connecting frame is installed at the output end of the motor, a strong magnet is installed on the connecting frame, a limiting ring is installed on the outer surface of the bottom end of the box body where the stirring module is located, the connecting frame and the strong magnet are limited through the limiting ring, a tray is installed inside the box body where the stirring module is located, a magnetic rotor is placed in the tray, and the magnetic rotor is driven by the motor and the strong magnet to rotate in the tray.
[0017] The beneficial effects of adopting the above further scheme are:
[0018] The magnetic stirring system adopts a non-contact stirring method, that is, the magnetic rotor rotates in the tray through magnetic force, without direct contact with the pickling solution. This design avoids the problems of wear and corrosion caused by the direct contact between mechanical components and the pickling solution in traditional stirrers, thus significantly extending the service life of the stirring module. Due to the reduction of wear and corrosion, the maintenance cost of the magnetic stirring system is also correspondingly reduced. Operators do not need to frequently replace worn parts, reducing the downtime and maintenance workload. The magnetic rotor rotates at a high speed in the tray, generating a strong swirling water flow, making the pickling solution fully mixed and contacted with the stainless steel wire rod. This uniform stirring method helps to improve the pickling efficiency and quality, and ensures that the surface of the stainless steel wire rod is thoroughly cleaned.
[0019] Furthermore, when the magnetic rotor rotates, it will generate a vortex inside the box, and the center of the vortex coincides with the axis of the tray. The precipitates generated during pickling will gather in the tray under the action of their own gravity and the vortex.
[0020] The beneficial effects of adopting the above further scheme are as follows:
[0021] The vortex generated by the rotation of the magnetic rotor in the tray helps the pickling solution to be evenly mixed inside the box, enabling the pickling solution to fully contact and act on the surface of the stainless steel wire rod, thereby improving the pickling efficiency. The flow characteristics of the vortex can strengthen the scouring effect on the surface of the stainless steel wire rod, helping to remove stubborn stains and impurities on the surface and enhancing the pickling effect. During the pickling process, the precipitates generated will gather towards the center of the vortex, that is, the position where the tray is located. Since the tray is located at the bottom of the box, the precipitates can naturally settle in the tray under the action of their own gravity, facilitating subsequent collection and treatment. Concentrating the precipitates in the tray can reduce the content of suspended solids in the pickling solution, reduce the pollution degree of the pickling solution, and is beneficial to environmental protection and equipment.
[0022] Furthermore, stainless steel tie bars are erected inside the box through brackets, and the pickling solution inside the box is stirred by a stirring module to fully contact the stainless steel tie bars.
[0023] The beneficial effects of adopting the above further scheme are as follows:
[0024] The stirring module generates a vortex or stirring force inside the box, enabling the pickling solution to fully and evenly cover all surfaces of the stainless steel tie bars. This all-round contact ensures that the pickling solution can penetrate into the tiny gaps and unevenness on the stainless steel surface, thereby more effectively removing impurities such as scale and rust. The full contact between the pickling solution and the stainless steel tie bars accelerates the chemical reaction process, making the pickling process faster and more efficient. This helps to shorten the production cycle and improve production efficiency. Since the pickling solution can fully contact all surfaces of the stainless steel tie bars, it can more thoroughly remove impurities such as scale and rust on the surface, improving the surface cleanliness and smoothness. The action of the stirring module makes the distribution of the pickling solution inside the box more uniform, thus ensuring that the stainless steel tie bars receive consistent treatment during pickling and helping to obtain a uniform pickling effect.
[0025] The present utility model provides a pickling device for stainless steel hot-rolled wire rods. It has the following beneficial effects:
[0026] By generating ultrasonic waves through ultrasonic probes, it can effectively promote the full contact between the pickling solution and the stainless steel wire rod, making the pickling process more uniform and efficient. The cavitation effect of ultrasonic waves can enhance the penetration ability of the pickling solution, improve the cleaning effect, and reduce the pickling time.
[0027] The circulation pump ensures the circulating flow of the pickling solution between the accommodation chamber and the pickling solution container, maintaining the activity and uniform temperature of the pickling solution. Meanwhile, the heating resistance belt heats inside the accommodation groove, which can maintain the pickling solution at an appropriate working temperature, further improving the pickling efficiency and effect.
[0028] The stirring module uses a motor to drive a strong magnet, and drives the magnetic rotor in the tray to rotate through magnetic force, generating a swirling water flow. This non-contact stirring method avoids the direct contact between mechanical components and the pickling solution, reducing wear and corrosion. At the same time, the generated swirl can effectively promote the mixing of the pickling solution and the stainless steel wire rod, improving the pickling quality.
[0029] The swirl generated by magnetic stirring enables the precipitates generated during the pickling process to naturally settle and accumulate in the tray, facilitating subsequent cleaning and separation. This not only reduces the pollution of the pickling solution, but also extends the service life of the pickling solution and reduces the operating cost. Brief Description of the Drawings

[0039] See also Figures 1 to 4 As shown, the embodiments provided by the utility model:
[0040] Embodiment 1
[0041] A stainless steel hot-rolled wire rod pickling device comprises a base 5, a box body 4 is mounted on the base 5, a conduit 405 is provided through one side of the box body 4, a circulating pump 7 is installed inside the base 5, the box body 4 is provided with a receiving chamber 406, and the receiving chamber 406 is connected with a pickling liquid container through the circulating pump 7, a receiving groove 403 is provided on the side wall and the bottom of the box body 4, and a thermal resistance belt 404 is installed in the receiving groove 403.
[0042] Embodiment 2
[0043] In order to make the pickling liquid fully contact with the stainless steel strip and increase the pickling rate, for example, Figures 1 to 4As shown in the figure, the present invention further includes: a fixed seat 3 is erected above the box body 4 through a cantilever 1. The base 5 is provided with a bottom plate 501, and the cantilever 1 and the circulation pump 7 are installed on the bottom plate 501 of the base 5. The bottom plate 501 is a basic component of the base 5, providing a solid and stable support platform for key components such as the cantilever 1 and the circulation pump 7. Through this design, the structural rigidity of the entire pickling device is significantly enhanced, enabling it to work more stably and reliably during operation, greatly reducing the risk of equipment shaking or damage caused by vibration or external forces. A fixed shaft 2 is inserted into the fixed seat 3, and an ultrasonic probe 201 is installed at the end of the fixed shaft 2. Ultrasonic waves are generated by the ultrasonic probe 201 to make the pickling solution fully contact the stainless steel wire rods. A stirring module 6 is installed at the bottom end of the box body 4. Stainless steel tie bars are erected in the box body 4 through brackets. The pickling solution in the box body 4 is stirred by the stirring module 6 to fully contact the stainless steel tie bars. The stirring module 6 generates a vortex or stirring force in the box body 4, enabling the pickling solution to fully and evenly cover all surfaces of the stainless steel tie bars. This all-round contact ensures that the pickling solution can penetrate into the tiny gaps and unevenness on the stainless steel surface, thereby more effectively removing impurities such as scale and rust. The full contact between the pickling solution and the stainless steel tie bars accelerates the chemical reaction process, making the pickling process more rapid and efficient. This helps to shorten the production cycle and improve production efficiency. Since the pickling solution can fully contact all surfaces of the stainless steel tie bars, it can more thoroughly remove impurities such as scale and rust on the surface, improving the surface cleanliness and smoothness. The role of the stirring module 6 makes the distribution of the pickling solution in the box body 4 more uniform, thus ensuring that the stainless steel tie bars receive consistent treatment during the pickling process, contributing to obtaining a uniform pickling effect. A top cover 401 is installed on the box body 4, and a clamping plate 402 is installed inside the box body 4. The stirring module 6 is limited and installed in the box body 4 through the clamping plate 402. The design of the top cover 401 is ingenious and can effectively seal the upper opening of the box body 4, thereby preventing the pickling solution from splashing out of the box body 4 due to stirring or ultrasonic waves during the pickling process. This not only ensures the full utilization of the pickling solution but also avoids the pollution of the pickling solution to the environment and the harm to the operators. Good sealing can also reduce the air exchange inside and outside the box body 4, contributing to maintaining the stability of parameters such as the concentration, temperature, and humidity of the pickling solution in the box body 4, thereby ensuring the consistency and controllability of the pickling process. The clamping plate 402, as a support and limiting device for the stirring module 6, can ensure the stability of the position and posture of the stirring module 6 in the box body 4.This stable support structure can effectively reduce the vibration and displacement generated by the stirring module 6 during operation, and reduce its impact on the box body 4 and other components. The stirring module 6 is provided with a motor 603, a connecting frame 604 is installed at the output end of the motor 603, and a strong magnet 605 is installed on the connecting frame 604. A limiting ring 602 is installed on the outer surface of the bottom end of the box body 4 where the stirring module 6 is located. The connecting frame 604 and the strong magnet 605 are limited by the limiting ring 602. A tray 606 is installed inside the box body 4 where the stirring module 6 is located, and a magnetic rotor 601 is placed in the tray 606. The magnetic rotor 601 is driven by the motor 603 and the strong magnet 605 to rotate in the tray 606. The magnetic stirring system adopts a non-contact stirring method, that is, the magnetic rotor 601 rotates in the tray 606 through magnetic force and does not need to be in direct contact with the pickling solution. This innovative design avoids the problems of wear and corrosion caused by the direct contact between mechanical components and the pickling solution in traditional stirrers, thus significantly extending the service life of the stirring module 6. At the same time, due to the reduction of wear and corrosion, the maintenance cost of the magnetic stirring system is also correspondingly reduced. Operators do not need to frequently replace worn parts, reducing the downtime and maintenance workload. The magnetic rotor 601 rotates at a high speed in the tray 606, generating a strong swirling water flow, which makes the pickling solution fully mix and contact with the stainless steel wire rods. This uniform stirring method helps to improve the pickling efficiency and quality, ensuring that the surface of the stainless steel wire rods is thoroughly cleaned. When the magnetic rotor 601 rotates, it will generate a vortex in the box body 4, and the center of the vortex coincides with the axis of the tray 606. The precipitate generated during pickling will gather in the tray 606 through its own gravity and the vortex. The vortex generated by the rotation of the magnetic rotor 601 in the tray 606 helps the pickling solution to be evenly mixed in the box body 4, enabling the pickling solution to fully contact and act on the surface of the stainless steel wire rods, thereby improving the pickling efficiency. The flow characteristics of the vortex can strengthen the scouring effect on the surface of the stainless steel wire rods, helping to remove stubborn stains and impurities on the surface and enhancing the pickling effect. The precipitate generated during the pickling process will gather towards the center of the vortex under the action of the vortex, that is, the position where the tray 606 is located. Since the tray 606 is located at the bottom of the box body 4, the precipitate can naturally settle in the tray 606 through its own gravity, facilitating subsequent collection and treatment. Concentrating the precipitate in the tray 606 can reduce the content of suspended solids in the pickling solution, reduce the pollution degree of the pickling solution, and is beneficial to environmental protection and equipment.
[0044] Working principle:
[0045] The circulating pump 7 is responsible for pumping the pickling solution out of the pickling solution container and transporting it through the conduit 405 into the accommodating cavity 406 of the box body 4. Subsequently, the pickling solution after the pickling process returns to the pickling solution container through the circulating pump 7, forming a closed-loop cycle. This circulating mechanism ensures the continuous utilization of the pickling solution and improves the pickling efficiency. The heating resistance tape 404 installed in the accommodating groove 403 maintains the pickling solution within an appropriate working temperature range through heating. An appropriate temperature can accelerate the chemical reaction rate of the pickling solution, improve the pickling effect, and reduce the pickling time.
[0046] Through the fixed shaft 2 inserted into the fixed seat 3, the ultrasonic probe 201 is installed above the box body 4. The ultrasonic waves generated by the ultrasonic probe 201 can penetrate the pickling solution and act on the surface of the stainless steel wire rod. The cavitation effect of the ultrasonic waves can enhance the penetration ability of the pickling solution, enabling the pickling solution to come into contact with the surface of the stainless steel wire rod more fully, thereby improving the pickling effect.
[0047] The motor 603 in the stirring module 6 drives the strong magnet 605 to rotate, and drives the magnetic rotor 601 in the tray 606 to rotate synchronously through magnetic force. The rotation of the magnetic rotor 601 generates a swirling water flow within the box body 4. This swirling water flow can drive the pickling solution to mix and contact with the stainless steel wire rod fully, improving the pickling quality. The swirl generated during magnetic stirring enables the sediment produced by pickling to settle naturally and accumulate in the tray 606. This design not only facilitates subsequent cleaning work but also effectively reduces the pollution and waste of the pickling solution.
