Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire pickling technology, and in particular relates to a wire pickling solution recovery device. Background Technology
[0002] Pickling is an important surface treatment process in the production and processing of metal wire. Its main purpose is to remove impurities such as oxide scale and rust from the surface of the wire using acidic solutions to ensure the quality of subsequent processing. However, pickling generates a large amount of acid mist, which not only contains corrosive components such as hydrochloric acid and sulfuric acid, but also has strong volatility.
[0003] Currently, the industry primarily uses simple condensation recovery devices for the recovery and treatment of pickling acid mist, whose core structure is typically a straight or short-path recovery pipeline. These devices have significant limitations in practical applications. Due to the short pipeline path and simple structure, the acid mist flows rapidly within the pipeline, resulting in short contact time with the cooling medium. This leads to insufficient condensation of the acid mist, and a large amount of uncondensed acid mist is directly released into the air. This not only wastes acidic solutions and increases production costs, but also poses a serious threat to the workshop environment and the health of operators, while accelerating equipment corrosion and aging.
[0004] To address these issues, we provide a wire pickling solution recovery device. Utility Model Content
[0005] The purpose of this invention is to provide a wire pickling solution recovery device. By setting the recovery pipe to a "U" shape, the residence time of acid mist in the cooling box can be extended, and the contact area with the coolant can be increased, thereby improving the condensation efficiency of acid mist and more fully converting acid mist into liquid solution for recovery. An acid mist detector is installed at the end of the recovery pipe away from the air inlet pipe, which can monitor the acid mist content in the remaining gas after condensation in real time. This solves the problem that existing recovery pipes have short paths and simple structures, and the acid mist flows quickly in the pipes, resulting in short contact time with the cooling medium, which leads to insufficient condensation of acid mist and a large amount of uncondensed acid mist being directly emitted into the air.

Specific Implementation Example 1
[0043] Please see Figure 1-7 This utility model is a wire pickling solution recovery device, including a cooling box 1, with several limiting tubes 2 fixed at the bottom of the cooling box 1; a box cover 3 is movably connected to the top of the cooling box 1, and several placement slots 4 are fixed to both the box cover 3 and one side of the cooling box 1; a recovery pipe 5 is movably connected inside the placement slots 4, with an air inlet pipe 6 fixed to one end of the recovery pipe 5; a first valve 7 is fixed to the end of the recovery pipe 5 near the air inlet pipe 6; an acid mist detector 8 is fixed to the end of the recovery pipe 5 away from the air inlet pipe 6, and a second valve 9 is fixed to the end of the recovery pipe 5 away from the first valve 7; a discharge pipe 10 is fixed to the middle of the recovery pipe 5, and a third valve 11 is fixed to the outside of the discharge pipe 10; the discharge pipe 10 passes through the limiting tubes 2, and a collection box 12 is fixed to the bottom of the discharge pipe 10.
[0044] Specifically, the recycling tube 5 has a "U" shaped structure; the limiting tube 2 has several sealing rings 13 fixed inside, and the sealing rings 13 are made of rubber.
[0045] Furthermore, a water inlet pipe 14 is fixed to the bottom of the cooling box 1, and a water outlet pipe 15 is fixed to the end of the cooling box 1 away from the water inlet pipe 14; the position of the water outlet pipe 15 is higher than that of the water inlet pipe 14.
[0046] The operation process of this embodiment is as follows: Before using this device, first confirm that the cooling box 1 and the box cover 3 are tightly closed, the recovery pipe 5 is stably installed inside the cooling box 1 through the placement groove 4, and the "U"-shaped section of the recovery pipe 5 is completely inside the cooling box 1. Check whether the discharge pipe 10 vertically penetrates the limiting pipe 2 and whether the rubber sealing ring 13 inside the limiting pipe 2 is intact to avoid leakage of coolant or condensate. Then, inject coolant into the box through the water inlet pipe 14 at the bottom of the cooling box 1 until the coolant flows out from the water outlet pipe 15 at the top of the cooling box 1. Because the water outlet pipe 15 is higher than the water inlet pipe 14, it can form a self-flowing... Convection is then used to ensure that the cooling tank 1 is filled with coolant. After preparation, the first valve 7 is opened to guide the acid mist generated during pickling into the "U"-shaped recovery pipe 5 through the air inlet pipe 6. As the acid mist flows along the recovery pipe 5, it gradually condenses into liquid because the recovery pipe 5 is in the coolant of the cooling tank 1. When a certain amount of condensate accumulates at the bottom of the "U"-shaped recovery pipe 5, the third valve 11 is opened, and the condensate flows into the collection tank 12 through the discharge pipe 10. After the liquid in the collection tank 12 reaches a certain amount, the third valve 11 is closed, and the collection tank 12 is removed for chemical recovery and reuse. During the process, the acid mist detector 8 at the end of the recovery pipe 5 continuously monitors the concentration of uncondensed acid mist. If the acid mist concentration exceeds the standard, the second valve 9 is closed and the input of acid mist is stopped. The cooling liquid in the cooling box 1 continues to cool the recovery pipe 5 until the acid mist is completely condensed. If the acid mist detector 8 shows that the acid mist concentration meets the standard, the second valve 9 can be opened to safely discharge the residual gas. In this device, the recovery pipe 5 adopts a "U"-shaped structure, which can prolong the residence time of acid mist in the cooling box 1 and increase the contact area with the cooling liquid, thereby improving the condensation efficiency of acid mist and more fully converting acid mist into liquid medicine. The system is designed for recycling, with the recycling pipe 5 movably connected to the cooling box 1 and the box cover 3 via the placement groove 4. This connection ensures a secure installation and facilitates disassembly and maintenance. Simultaneously, the discharge pipe 10 connected to the pipe passes through the limiting pipe 2. The rubber sealing ring 13 inside the limiting pipe 2 enhances the sealing performance, effectively preventing leakage of coolant or condensed pharmaceutical solution, thus ensuring the safety and environmental friendliness of the recycling process. An acid mist detector 8 is installed at the end of the recycling pipe 5 furthest from the inlet pipe 6, which can monitor the acid mist content in the remaining gas after condensation in real time. This allows for timely adjustments to the recycling operation, preventing the direct emission of incompletely condensed acid mist and reducing environmental pollution. Specific Implementation Example 2
[0048] Please see Figure 5-7 Based on the first specific embodiment, an adjustment shell 16 is fixed to the top of the box cover 3; a limit groove 17 is opened on both sides of the adjustment shell 16, and a limit block 18 is slidably connected inside the limit groove 17; an adjustment plate 19 is fixed to one side of the limit block 18, and a connecting rod 20 is fixed to the bottom of the adjustment plate 19; a stirring plate 21 is fixed to the bottom of the connecting rod 20, and a plurality of stirring grooves 22 are opened on the surface of the stirring plate 21.
[0049] Specifically, a motor 23 is fixed inside the regulating shell 16, and a transmission block 24 is fixed to the output shaft of the motor 23; the transmission block 24 has an elliptical structure.
[0050] Furthermore, a connecting plate 25 is fixed inside the adjusting shell 16; a telescopic rod 26 is fixed between the connecting plate 25 and the adjusting plate 19, and a tension spring 27 is sleeved on the outside of the telescopic rod 26; one end of the tension spring 27 is fixedly connected to the connecting plate 25, and the other end of the tension spring 27 is fixedly connected to the adjusting plate 19.
[0051] The operation process of this embodiment is as follows: During the acid mist condensation process, the motor 23 inside the regulating shell 16 is started. The output shaft of the motor 23 drives the elliptical transmission block 24 to rotate. When the transmission block 24 rotates, its elliptical structure will periodically push the regulating plate 19 to move upward. At the same time, the tension spring 27 between the regulating plate 19 and the connecting plate 25 generates tension due to deformation, pulling the regulating plate 19 downward, forming a reciprocating motion. The regulating plate 19 drives the bottom stirring plate 21 to move up and down in the cooling box 1 through the connecting rod 20. The stirring groove 22 on the surface of the stirring plate 21 can enhance the disturbance of the coolant. The stirring plate 21 stirs the coolant in the cooling box 1 by moving up and down. With the addition of several stirring grooves 22 on the surface, it can enhance the fluidity of the coolant, make the temperature of the coolant in the cooling box more uniform, improve the heat exchange efficiency with the recovery pipe 5, and accelerate the acid mist condensation.
