Description

Technical Field

[0001] The invention relates to the technical field of stainless steel drawing wire cleaning, in particular to a stainless steel drawing wire cleaning device. Background Art

[0002] Stainless steel wire drawing is a type of stainless steel product. After forming, some impurities and oxide layers remain on the surface. Due to its slender shape, stainless steel wire drawing is less suitable for automated pickling methods, and pickling is prone to uneven or inadequate pickling. Summary of the Invention

[0003] Based on this, it is necessary to provide a stainless steel wire drawing wire cleaning device.

[0004] A stainless steel wire drawing cleaning device comprises a detection chamber and at least two pickling chambers connected in sequence, a transmission channel is provided through the detection chamber and each of the pickling chambers, a plurality of pickling nozzles are provided in each of the pickling chambers, each of the pickling nozzles is arranged toward the transmission channel, the pickling nozzles in the same pickling chamber are arranged in the same direction and are respectively arranged along the extension direction of the transmission channel, and the pickling nozzles in different pickling chambers are arranged in different directions; wherein, the detection chamber is provided with a detection component for detecting the oxidized area of ​​the stainless steel wire drawing, and the pickling nozzle in each of the pickling chambers is used to clean the corresponding oxidized area.

[0005] In the above-mentioned stainless steel wire drawing cleaning device, the stainless steel wire drawing is transmitted into the transmission channel and passes through the detection chamber and other pickling chambers in sequence. The part entering the detection chamber detects the oxidation area and then enters the pickling chamber. When the oxidation area is exactly within the spray range of the pickling nozzle of the pickling chamber, the pickling nozzle sprays acid to clean the oxidation area. The pickling nozzles in the pickling chamber are all facing in the same direction, and there will be no interference between the acid liquids. The spray pressure of the acid liquid can be maintained at a high level, thereby better washing away the impurities and oxide layer in the oxidation area. When the oxidation area is not within the spray range of the pickling nozzle of the pickling chamber, the pickling treatment is not performed in the pickling chamber to prevent the acid liquid from corroding the surface of the stainless steel wire drawing. As the stainless steel wire drawing enters the next pickling chamber, whether to spray acid liquid is determined based on whether the oxidation area is within the spray range of the pickling nozzle. Thus, multiple pickling chambers pickle different positions of the stainless steel wire drawing respectively, avoiding interference between acid liquids in different directions. This device is particularly suitable for continuously produced stainless steel products such as drawn stainless steel wire, enabling precise and effective pickling of oxidized areas. Furthermore, the stainless steel wire cleaning device works well with the stainless steel wire manufacturing device. After being produced, the drawn stainless steel wire directly enters the conveyor channel for continued cleaning, making it well-suited for automated production.

[0006] More specifically, the cleaning method of the cleaning device includes:

[0007] The surface of the continuously passing stainless steel drawn wire is divided into a plurality of circumferentially distributed detection areas, wherein the spray range of the pickling nozzle of each pickling chamber is used to correspond to a detection area, that is, the pickling nozzle in each pickling chamber is used to be set toward a detection area.

[0008] Identify the oxidized area of ​​the stainless steel drawn wire, determine the detection area in which the oxidized area falls, and obtain the target pickling area. Specifically, the detection component divides the surface of the continuously passing stainless steel drawn wire into multiple circumferentially distributed detection areas, and then identifies the oxidized area of ​​the stainless steel drawn wire, determines the detection area in which the oxidized area falls, and obtains the target pickling area.

[0009] The target pickling areas are pickled in sequence. Specifically, when the stainless steel wire rod passes through each pickling chamber in sequence, the pickling nozzles with a spray range corresponding to the target pickling area perform the acid spraying work.

[0010] This allows for precise and effective pickling of the oxidized areas of the stainless steel drawn wire.

[0011] In one embodiment, the detection component is used to detect the current grayscale of the stainless steel drawn wire and compare the current grayscale with a standard grayscale to determine the oxidation area of ​​the stainless steel drawn wire.

[0012] In one embodiment, it further includes a control component and multiple pump components, the control component is electrically connected to the detection component and each pump component, each pump component is used to connect to each pickling nozzle in a pickling chamber, and the control component is used to control the operation of the corresponding pump component according to the oxidation area to make the corresponding pickling nozzle work.

[0013] In one embodiment, the detection component is further used to detect the oxidation degree of the oxidation area, and the control component is used to control the pickling nozzle of the corresponding pickling chamber to work for a preset time according to the oxidation area.

[0014] In one embodiment, the water washing chamber is arranged between the acid washing chamber and the detection chamber.

[0015] In one embodiment, the water washing chamber is provided with a water washing nozzle for spraying water at 50-70°C.

[0016] In one embodiment, the method further includes a blowing chamber, wherein the blowing chamber is arranged between the water washing chamber and the acid washing chamber.

[0017] In one embodiment, the blowing chamber is provided with a blower for blowing out air at a temperature of 50 to 70°C.

[0018] In one embodiment, a static electricity removal chamber is further included, and the static electricity removal chamber is arranged between the water washing chamber and the detection chamber.

[0019] In one embodiment, each of the pickling chambers is provided with an air inlet channel and an air outlet channel, wherein the air inlet channel is provided on a side of the pickling chamber close to the pickling nozzle, and the air outlet channel is provided on the opposite side of the air inlet channel, wherein the air inlet channel is used to introduce a mixed gas containing chlorine.

[0028] For ease of understanding of the present application, the present application will be described more fully below. The present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the description of this application, the meaning of "several" is at least one, such as one, two, etc., unless otherwise clearly and specifically defined.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] In this application, the technical features described in an open manner include closed technical solutions composed of the listed features, and also include open technical solutions containing the listed features.

[0032] During the spray pickling process of stainless steel wire drawing, an oxide layer adheres to the stainless steel wire drawing, but the oxide layer is not present in one piece. The spray speed of the acid solution has a significant impact on the pickling effect. The greater the spray speed, the easier it is for the acid solution to penetrate into the oxide layer, thereby breaking down the oxide layer from the inside. However, if the conventional pickling device in the prior art is used to increase the spray speed of the acid solution for pickling, it is easy to cause corrosion to the steel body that is not covered with the oxide layer. If the spray speed is lowered for pickling, the oxide layer of the stainless steel wire drawing will not be fully pickled. Therefore, there is an urgent need for a cleaning device that can accurately and efficiently clean stainless steel wire drawing.

[0033] like Figure 1 As shown, in one embodiment, a stainless steel drawn wire 800 cleaning device 10 is provided, comprising a detection chamber 100 and at least two pickling chambers 200 connected in sequence, a transmission channel 109 is provided through the detection chamber 100 and each of the pickling chambers 200, and a plurality of pickling nozzles 300 are provided in each of the pickling chambers 200, and each of the pickling nozzles 300 is arranged toward the transmission channel 109, and the transmission channel 109 is used to be arranged corresponding to the unloading end of the stainless steel drawn wire 800 manufacturing device.

[0034] The pickling nozzles 300 in the same pickling chamber 200 are arranged in the same direction and are arranged along the extension direction of the transfer channel 109. The extension direction of the transfer channel is the direction from the detection chamber to the pickling chamber, or in other words, the pickling nozzles are arranged along the transfer direction of the transfer channel 109. The pickling nozzles 300 in different pickling chambers 200 are arranged in different directions.

[0035] The inspection chamber 100 is provided with an inspection assembly 110 for inspecting the oxidized areas of the stainless steel drawn wire 800. The pickling nozzle 300 in each pickling chamber 200 is used to clean the corresponding oxidized area. More specifically, the pickling nozzle 300 in each pickling chamber 200 is used to clean the oxidized area it is directed toward. Specifically, the stainless steel drawn wire 800 moves along the conveying channel 109 and sequentially passes through the inspection chamber 100 and each pickling chamber 200.

[0036] When the stainless steel wire drawing 800 passes through the inspection chamber 100, the inspection assembly 110 divides the surface of the continuously passing stainless steel wire drawing 800 into a plurality of circumferentially distributed inspection areas. The spray range of the pickling nozzle 300 in each pickling chamber 200 is used to correspond to a detection area, and the oxidized area of ​​the stainless steel wire drawing 800 is identified. The inspection area in which the oxidized area falls is determined to obtain the target pickling area. When the stainless steel wire drawing 800 passes through each pickling chamber 200 in sequence, the pickling nozzle 300 whose spray range corresponds to the target pickling area performs the acid spraying operation. Among them, the detection area can be an area of ​​the same area or an area of ​​different areas. For example, according to the surface shape of the stainless steel drawn wire and the direction of the pickling nozzle, the detection areas of different areas are divided. In this way, detection areas of different sizes can be set according to the influence of gravity. For example, the acid sprayed from bottom to top will be affected by gravity and slowed down, and the pickling effect is poor. At this time, the pickling nozzle can be set closer to the middle of the transmission channel to make the distance between the pickling nozzle and the stainless steel drawn wire closer to increase the pickling effect. In this way, the spray range of the pickling nozzle is smaller. At this time, the area of ​​the detection area at this position is reduced to better adapt to the spray range of the pickling nozzle.

[0037] In the above-mentioned stainless steel wire drawing cleaning device 10, the stainless steel wire drawing wire 800 is transmitted to the transmission channel 109 and passes through the detection chamber 100 and other pickling chambers 200 in sequence. After the part entering the detection chamber 100 detects the oxidized area, it enters the pickling chamber 200. When the oxidized area is just within the spray range of the pickling nozzle 300 of the pickling chamber 200, the pickling nozzle 300 sprays acid to clean the oxidized area. The pickling nozzles 300 in the pickling chamber 200 are all facing in one direction, and there will be no mutual interference of the acid, which can make the injection speed of the acid not affected by interference, thereby better washing away the impurities and oxide layer in the oxidized area. When the oxidized area is not within the spray range of the pickling nozzle 300 of the pickling chamber 200, no pickling treatment is performed in the pickling chamber 200 to prevent the acid from corroding the surface of the stainless steel wire drawing wire 800. As the stainless steel wire 800 enters the next pickling chamber 200, the decision to spray acid is made based on whether the oxidized area is within the spray range of the pickling nozzle 300. Thus, multiple pickling chambers 200 each pickle different locations on the stainless steel wire, preventing interference between acids from different directions. This system is particularly suitable for continuously produced stainless steel products such as stainless steel wire, enabling precise and effective pickling of oxidized areas on the wire and enabling the acid spray rate to be increased to avoid uneven pickling.

[0038] It is worth mentioning that when acid liquids from different directions are sprayed on the surface of stainless steel brushed wire, the acid liquids from the two directions will collide at the junction to form a confluence area. The acid liquids in the confluence area are not easy to drain, so the pickling effect at the position corresponding to the confluence area is not good, and the acid liquids from different directions are also prone to collide in the air and slow down. In this application, the acid liquids from different directions are sprayed independently, so that the acid liquids can better contact and drain, the pickling effect is better, and the pickling of the surface of the stainless steel brushed wire is also more uniform.

[0039] like Figure 1 As shown, in one embodiment, the stainless steel wire drawing cleaning device 10 includes a detection chamber 100 and four pickling chambers 200 connected in sequence, and the four pickling chambers 200 respectively include a first pickling chamber 210, a second pickling chamber 220, a third pickling chamber 230 and a fourth pickling chamber 240 from right to left, wherein each pickling chamber 200 is provided with two pickling nozzles 300, wherein the pickling nozzles 300 in the same pickling chamber 200 are arranged in the same direction and are respectively arranged along the extension direction of the conveying channel 109, and the pickling nozzles 300 in the four pickling chambers 200 are oriented in different directions. Figure 1 From the perspective of the pickling chamber 200, the pickling nozzles 300 in different pickling chambers 200 are respectively facing downward, backward, forward and upward, corresponding to the surrounding surfaces of the stainless steel wire drawing wire 800. It is worth noting that due to Figure 1In this cross-sectional view, the front pickling nozzle 300 is cut away, and thus the front pickling nozzle 300 is indicated by a dotted line.

[0040] like Figures 2 to 5 As shown, there are four more detailed cross-sectional schematic diagrams of the pickling chambers 200. The direction of this perspective is the same as the direction of the conveying channel 109. The four directions of the pickling nozzle 300 of each pickling chamber 200 are downward, left, right and upward, respectively. The four directions correspond to the surrounding surfaces of the stainless steel drawn wire 800, so that the surrounding surfaces of the stainless steel drawn wire 800 are pickled in turn.

[0041] The stainless steel wire drawing material 800 of this embodiment has four detection areas, such as Figure 6 As shown, they are upper surface 810, lower surface 820, left surface 830 and right surface 840 respectively.

[0042] Specifically, please combine Figure 1 、 Figure 2 and Figure 6 As shown, when the stainless steel wire drawing wire 800 passes through the inspection chamber 100, oxidized areas 805 are detected on the left surface 830 and the right surface 840. Next, when the stainless steel wire drawing wire 800 passes through the first pickling chamber 210, the pickling nozzle 311 of the first pickling chamber 210 does not spray acid because the inspection assembly 110 recognizes that there are no oxidized areas on the upper surface 810 of the stainless steel wire drawing wire 800 or that the oxide layer of the oxidized areas is within an acceptable range. This prevents corrosion of the steel body of the stainless steel wire drawing wire 800.

[0043] like Figure 3 As shown, when the stainless steel wire drawing wire 800 passes through the second pickling chamber 220, the pickling nozzle 300 works to remove the oxide layer of the oxidized area 805 on the right surface 840 of the stainless steel wire drawing wire 800. Specifically, an acid collecting chamber 323 is provided at the bottom of the pickling chamber 200. The pickling chamber 200 includes an inner liner 240 and an outer shell 250, wherein an acid discharge pump 320 is provided between the inner liner 240 and the outer shell 250, and the inner liner 240 is provided with a drainage channel 241 for discharging waste liquid. The acid discharge pump 320 works to drive the acid in the acid collecting chamber 323 to be transported to the pickling nozzle 321, thereby realizing pickling treatment of the stainless steel wire drawing wire 800. The acid collecting chamber 323 is arranged at the bottom to make it easier for the acid discharge pump 320 to extract, reduce energy consumption, and enable the acid to be sprayed onto the surface of the stainless steel wire drawing wire 800 at a faster speed.

[0044] like Figure 4 As shown, when the stainless steel drawn wire 800 passes through the third pickling chamber 230 , the pickling nozzle 331 works to remove the oxide layer on the oxidized area of ​​the left surface 830 of the stainless steel drawn wire 800 .

[0045] like Figure 5 As shown, when the stainless steel drawn wire 800 passes through the fourth pickling chamber 240, the pickling nozzle 341 of the fourth pickling chamber 240 does not spray acid because there is no oxidized area on the lower surface 820 of the stainless steel drawn wire 800 or the oxide layer of the oxidized area is within an acceptable range.

[0046] In this way, the four inspection areas of the stainless steel drawn wire 800 are pickled independently, avoiding the mutual interference of acid splashing in different directions, allowing the acid to maintain a high spray speed to facilitate the acid to penetrate into the oxide layer, and avoiding acid pickling in areas without oxidation, thereby accurately improving the pickling effect on specific positions of the stainless steel drawn wire.

[0047] Furthermore, in this embodiment, the stainless steel wire drawing material first passes through the downward pickling nozzle. This is because when the downward pickling nozzle is in operation, the acid will flow along the upper surface of the stainless steel wire drawing material to the two side surfaces. If the side surfaces are arranged in front, then after the side surfaces are pickled clean, the acid on the upper surface will directly contact the side surfaces, thereby damaging the steel body of the stainless steel wire drawing material. Therefore, it is better to pickle the upper surface first, then pickle the lower surface, and finally pickle the lower surface. Therefore, in one embodiment, the pickling nozzles of each pickling chamber are arranged from top to bottom, and the orientation of the pickling nozzles is arranged from bottom to top, so as to pickle the stainless steel wire drawing material from top to bottom.

[0048] In one embodiment, the detection component 110 is used to detect the current grayscale of the stainless steel wire drawing material and compare the current grayscale with the standard grayscale to determine the oxidized area of ​​the stainless steel wire drawing material. When an oxide layer or impurities exist on the surface of the stainless steel wire drawing material, the grayscale of the oxide layer and impurities is different from the standard grayscale of the stainless steel material surface. By comparing the difference between the current grayscale and the standard grayscale, the oxidized area on the surface of the stainless steel wire drawing material can be determined. It is worth mentioning that the degree of oxidation of the oxidized area can be determined based on the difference between the current grayscale and the standard grayscale.

[0049] Please refer again Figure 2In one embodiment, the stainless steel wire drawing cleaning device 10 further includes a control assembly (not shown) and a plurality of pump assemblies 320. The control assembly is electrically connected to the detection assembly 110 and each of the pump assemblies 320. Each pump assembly 320 is configured to connect to each of the pickling nozzles 300 within a pickling chamber 200. The control assembly is configured to control the operation of the corresponding pump assembly 320 based on the oxidation zone, thereby causing the corresponding pickling nozzle 300 to operate. The pump assembly 320 includes a pump body and a connected pipeline, configured to transport acid from the acid reservoir to the pickling nozzle 300. The control assembly controls the operation of the pump assembly 320, thereby controlling the pickling nozzle 300 to selectively spray acid. Specifically, the pump body is an acid discharge pump that is resistant to acid corrosion and can transport acid. It is worth noting that the detection component 110 divides the stainless steel wire 800 into multiple segments and continuously detects them. Based on the speed of the stainless steel wire 800, the control component can control the pickling nozzle 300 to perform the pickling operation when the oxidation zone reaches the corresponding pickling chamber 200. For example, the control component includes a control chip. In another example, the control chip includes a computer.

[0050] In one embodiment, the detection component 110 is further configured to detect the degree of oxidation in the oxidized area, and the control component is configured to control the pickling nozzle 300 in the corresponding pickling chamber 200 to operate for a preset duration based on the oxidized area. In this embodiment, if the degree of oxidation in the oxidized area is low, the pickling nozzle 300 is controlled to operate for a shorter duration and / or the spraying speed of the pickling nozzle 300 is controlled to decrease. If the degree of oxidation in the oxidized area is high, the pickling nozzle 300 is controlled to operate for a longer duration and / or the spraying speed of the pickling nozzle 300 is controlled to increase. The pickling duration and the acid spraying speed will affect the degree of pickling. Selecting an appropriate pickling degree based on the degree of oxidation can minimize the occurrence of acid corrosion on the steel body of the stainless steel wire. Specifically, the detection component includes a camera configured to capture an image of the surface of the stainless steel wire and convert it into a grayscale image to obtain a current grayscale. By comparing the current grayscale with a standard grayscale, the oxidized area and the degree of oxidation of the oxidized area can be determined.

[0051] like Figure 7 As shown, in one embodiment, the stainless steel wire drawing cleaning device 10 further includes a water washing chamber 400, which is disposed between the pickling chamber 200 and the detection chamber 100. Cleaning impurities from the surface of the stainless steel wire drawing 800 prior to the water washing chamber 400 can reduce the consumption of subsequent acid cleaning. Furthermore, the water washing chamber 400 can form a water curtain, preventing acid from evaporating into the detection chamber 100 and corroding the detection assembly 110, thereby better protecting the detection assembly 110.

[0052] In this embodiment, the water washing chamber 400 is equipped with a water washing nozzle 410 for spraying water at a temperature of 50-70°C. In this embodiment, spraying water at a temperature of 50-70°C helps maintain the stainless steel wire 800 at a temperature above room temperature. During the subsequent pickling process, this helps increase the reaction rate when the acid comes into contact with the higher-temperature stainless steel wire 800, thereby improving the pickling efficiency. Furthermore, the gas generated by the reaction between the acid and the stainless steel wire 800 is more likely to expand due to the higher temperature. This expanded gas can break through the oxide layer, achieving a more effective pickling effect. For example, this expanding gas is hydrogen.

[0053] In this embodiment, the stainless steel wire drawing cleaning device 10 further includes a blowing chamber 500, which is arranged between the water washing chamber 400 and the pickling chamber 200. The blowing chamber 500 can dry the surface of the stainless steel wire drawing 800, thereby avoiding water stains that dilute the acid solution, making the pickling effect better, and allowing the acid solution to better contact the stainless steel wire drawing 800, thereby reducing the consumption of acid solution. In other embodiments, a blowing chamber is provided between the two pickling chambers. During the blowing process, the blowing chamber can easily drive the flow of gas attached to the surface of the stainless steel wire drawing, or the wind can be blown into the micro-cavities created by the gas, thereby propping up the oxide layer debris that is about to fall off, better removing the oxide layer and impurities of the stainless steel wire drawing, and further avoiding the consumption of acid solution. In another embodiment, the water washing chamber is arranged on the side of the detection chamber away from the pickling chamber, and the blowing chamber is located between the water washing chamber and the detection chamber. In this way, the stainless steel wire drawing is first washed and dried to clean up impurities that are easy to fall off the surface of the stainless steel wire drawing before entering the detection chamber. This can more accurately detect the oxidized area that needs pickling. The blowing chamber blows away the water stains on the surface of the stainless steel wire drawing, which can avoid optical interference caused by the water stains, so that the detection component can better identify the oxidized area.

[0054] In this embodiment, the blowing chamber 500 is equipped with a fan 510 for blowing air at a temperature of 50-70°C. In this embodiment, the fan 510 blows air at a temperature of 50-70°C, which helps to increase the surface temperature of the stainless steel wire 800, allowing the surface of the stainless steel wire 800 to enter the pickling chamber 200 at a temperature higher than room temperature, thereby improving the pickling efficiency. In this embodiment, the air outlet of the fan 510 is tilted toward the pickling chamber 200, thereby transporting the volatilized acid toward the pickling chamber 200, minimizing the acid from volatilizing toward the water washing chamber 400 and the detection chamber 100, thereby protecting the detection assembly 110. In this embodiment, the number of fans 510 is at least two. Taking two as an example, the fans 510 are arranged along the extension direction of the conveying channel 109, wherein the fan 510 close to the water washing chamber 400 is inclined toward the pickling chamber 200, and the fan 510 close to the pickling chamber 200 is arranged toward the bottom of the blowing chamber 500. In this way, the fan 510 close to the water washing chamber 400 blows the water stains on the surface of the stainless steel drawn wire 800 toward the pickling chamber 200, while the fan 510 close to the pickling chamber 200 blows the nearby water stains toward the bottom of the pickling chamber 200, thereby preventing water from entering the pickling chamber 200.

[0055] The cleaning device 10 for the stainless steel wire drawing further includes a static electricity removal chamber 600, which is disposed between the water washing chamber 400 and the detection chamber 100. Specifically, the static electricity removal chamber 600 includes an ion blower 610. The charged particles generated by the ion blower 610 can neutralize the static electricity on the surface of the stainless steel wire drawing 800. In this way, some impurities that adhere to the surface of the stainless steel wire drawing 800 due to static electricity can be more easily removed by water washing.

[0056] In one embodiment, a conveying assembly is provided in the conveying channel for conveying the stainless steel wire drawing wire 800. Figure 7 The conveying assembly in this embodiment includes a plurality of conveying rollers 700, each of which is arranged in parallel and arranged along the conveying channel 109 to convey the stainless steel drawn wire 800. It can be understood that the conveying assembly can also adopt other forms of the prior art, and this application will not elaborate on them. In one embodiment, the conveying assembly is provided with an electrostatic generating assembly for passing static electricity into the conveying rollers 700 located in the pickling chamber 200. In this way, static electricity will be generated on the surface of the stainless steel drawn wire 800 again, which is conducive to attracting hydrogen ions to move to the surface of the stainless steel drawn wire 800 and improving the pickling effect. In another embodiment, an electrostatic chamber is provided between the detection chamber and the pickling chamber, and a discharge device is provided in the electrostatic chamber for releasing static electricity to the stainless steel drawn wire. In this way, static electricity can be released on the surface of the stainless steel drawn wire before it enters the pickling chamber, so that the stainless steel drawn wire attracts hydrogen ions and improves the pickling effect.

[0057] like Figure 8As shown, in one embodiment, the pickling chamber 200 is provided with an air inlet channel 291 and an air outlet channel 292. In this embodiment, the air outlet channel 292 is provided with a vacuum pump 280, which is connected to the drainage channel 241. The air inlet channel 291 is provided on a side of the pickling chamber 200 close to the pickling nozzle 321, and the air outlet channel 292 is provided on the opposite side of the air inlet channel 291. An air duct is formed between the air inlet channel 291 and the air outlet channel 292. The wind in the air duct increases the speed of the acid solution, thereby causing the acid solution to be sprayed onto the surface of the stainless steel wire drawing 800 at a faster speed. The air pressure in the pickling chamber 200 can also be adjusted by the air inlet channel 291 and the air outlet channel 292, thereby reducing the splash resistance of the acid solution and causing the acid solution to be sprayed onto the surface of the stainless steel wire drawing 800 at a faster speed. Furthermore, a mixed gas containing chlorine can be introduced into the pickling chamber 200 through the air inlet channel 291. The chlorine can act on the surface of the stainless steel together with the acidic substances in the pickling solution to accelerate the dissolution of the oxide layer, thereby improving the pickling effect. It is particularly suitable for continuous production lines with short pickling times such as stainless steel drawn wire 800. In one embodiment, the air inlet channel 291 and the air outlet channel 292 are only provided in the first few pickling chambers 200. For example, in this embodiment, they are opened in the second pickling chamber 220, but not in the last pickling chamber 200. This is because a higher pickling efficiency is required in the early stage of pickling, and the stainless steel drawn wire 800 entering the last pickling chamber 200 has already been pickled, so the pickling efficiency can be lowered to avoid corrosion of the steel body of the stainless steel drawn wire 800. In particular, when the pickling nozzle 321 of the last pickling chamber 200 sprays acid from bottom to top, there is acid at the bottom of the pickling chamber 200. The air inlet channel 291 opened at the bottom of the pickling chamber 200 will be filled with acid, and the waste acid will be easily sprayed onto the surface of the stainless steel wire drawing wire 800. When the pickling nozzle 321 is set at the top of the pickling chamber 200, the air inlet channel 291 is opened at the top of the pickling chamber 200, and the air outlet channel 292 is opened at the bottom of the pickling chamber 200. This allows the air and acid to be discharged at the same time, and the spraying effect is better.
