[0057] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the reasons why the zinc slag on the surface of the zinc liquid is difficult to gather and clean in the related art, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0058] In the related art, the hot-dip galvanizing process is a commonly used metal anti-corrosion method. Its principle is to prevent oxidation and corrosion by coating the metal surface with a layer of zinc. This process is also called hot-dip galvanizing or hot-dip galvanizing, which is a technology for immersing metals such as strip steel into molten liquid metal or alloy to obtain a coating. Specifically, the hot-dip galvanizing process can be divided into three main parts: pre-treatment, hot-dip galvanizing and post-treatment. The main purpose of pre-treatment is to remove oil, dust and rust from the surface of workpieces such as strip steel, which usually includes degreasing (if necessary), pickling, reduction, water washing, plating assistance and drying. These steps ensure that the workpiece is in a clean and activated state before hot-dip galvanizing. In the hot-dip galvanizing stage, the pre-treated workpiece is immersed in a molten zinc liquid at a temperature of about 450°C. In this process, zinc reacts and diffuses with the metal surface to form a uniform and dense zinc-iron alloy coating. This coating has excellent corrosion resistance and can provide long-lasting corrosion protection in outdoor equipment, building structures, pipelines, power equipment and other fields. In the post-processing stage, the galvanized workpiece is cooled and passivated to ensure that the coating on its surface has the best performance. Among them, cooling usually uses air cooling or water cooling to quickly convert the surface liquid zinc into solid crystalline zinc. Passivation is to prevent the workpiece from generating white rust during long-term storage and transportation. In general, the hot-dip galvanizing process is an effective metal anti-corrosion method. Its coating is uniform and dense, and has strong corrosion resistance, which can greatly extend the service life of metal products. At the same time, this process also has the advantages of simple operation and low cost, so it has been widely used in various fields.

[0059] During the hot-dip galvanizing process of steel strips, zinc material is continuously added to the zinc pot, and the zinc material will also bring in a lot of impurities into the zinc pot, which will generate a large amount of scum (zinc slag) on ​​the surface of the zinc liquid. If it is not cleaned in time, it will have a significant impact on the galvanizing quality of the steel strip surface. At present, the zinc slag in the zinc pot is manually removed by tools. In the process of manually removing the zinc slag, it is not easy to gather the zinc slag together, and the operation is difficult.

[0060] To this end, the present application provides a slag removal device, which includes a slag scraping mechanism, which includes a first slag scraping plate and a second slag scraping plate; during the slag scraping process, the first slag scraping plate is driven by a first driving member to scrape the zinc slag located in the middle area of ​​the zinc liquid surface to both sides of the zinc pot, and the second slag scraping plate is driven by a second driving member to scrape the zinc slag close to both sides of the zinc pot from one end to the other end for aggregation, so as to facilitate the centralized cleaning of the zinc slag; thereby solving the technical problem in the prior art that the zinc slag in the zinc pot is difficult to aggregate and is not conducive to removal.

[0061] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0062] For reference Figures 1 to 3 , Figure 1 A schematic diagram of a top view of the structure of a slag removal device provided in some embodiments of the present application applied to a zinc pot; Figure 2 A schematic diagram of the connection structure between the second scraping plate and the second driving member provided in some embodiments of the present application; Figure 3 A schematic diagram of the connection structure between the slag bucket and the third driving member provided in some embodiments of the present application.

[0063] In an embodiment of the present application, a slag removal device is provided, such as Figures 1 to 3 As shown, the slag removal device is mainly used to clean the zinc slag floating on the surface of the zinc liquid in the zinc pot 1. When the slag removal operation is performed, the slag removal device and the zinc pot 1 have a relative positional relationship. In order to facilitate the description of the positional relationship between the two, the orientation of the zinc pot 1 is first determined; specifically, the zinc pot 1 has a first end 11 and a second end 12 relatively arranged along a first direction X, and the zinc pot 1 also has a first side 13 and a second side 14 relatively arranged along a second direction Z; wherein the first direction X is perpendicular to the second direction Z and both are parallel to the surface of the zinc liquid.

[0064] In this embodiment, the slag removal device includes a slag scraping mechanism, which includes a first slag scraping plate 21, a first driving member 22, a second slag scraping plate 31 and a second driving member 32. The first driving member 22 is used to drive the first slag scraping plate 21 to perform a slag scraping action, and the second driving member 32 is used to drive the second slag scraping plate 31 to perform a slag scraping action.

[0065] In the process of slagging, the main function of the first slagging plate 21 is to sludge the zinc slag floating in the middle area of ​​the zinc liquid surface toward the side of the zinc pot 1 along the second direction Z. Specifically, at least in the case of slagging operation, the first slagging plate 21 is arranged in the area near the first end 11 in the zinc pot 1, and the first slagging plate 21 can be driven by the first driving member 22 and sludge the zinc slag located in the middle area of ​​the zinc liquid surface toward the first side 13 and / or the second side 14, that is, the first slagging plate 21 can sludge the zinc slag in the middle area of ​​the zinc liquid surface only toward the first side 13, or the first slagging plate 21 can sludge the zinc slag in the middle area of ​​the zinc liquid surface only toward the second side 14, or the first slagging plate 21 can sludge the zinc slag in the middle area of ​​the zinc liquid surface toward the first side 13 and the second side 14 respectively.

[0066] Optionally, the first scraping plate 21 may be disposed in the middle area of ​​the zinc liquid surface, so that the first scraping plate 21 can scrape slag toward both the first side 13 and the second side 14 .

[0067] Optionally, during operation, the bottom of the first slag scraping plate 21 may be slightly higher than the zinc liquid level. While ensuring that the first slag scraping plate 21 can scrape the zinc slag, the large fluctuation effect of the first slag scraping plate 21 on the zinc liquid can be reduced, thereby avoiding affecting the galvanizing process of the strip.

[0068] In the process of slagging, the second slagging plate 31 mainly functions to collect the zinc slag floating on both sides of the zinc liquid surface from the first end 11 close to the zinc pot 1 to the gathering area close to the second end 12, so as to facilitate centralized cleaning. Specifically, at least in the case of slagging operation, the second slagging plate 31 is arranged in the area close to the first side 13 and / or the second side 14 in the zinc pot 1, and the second slagging plate 31 can be driven by the second driving member 32 to slagging the zinc slag close to the first side 13 and / or the second side 14 from the first end 11 to the second end 12. The second scraping plate 31 is used in conjunction with the first scraping plate 21. When the first scraping plate 21 scrapes only toward the first side 13, the second scraping plate 31 can be arranged in an area near the first side 13 in the zinc pot 1, and the zinc slag in the corresponding area is scraped from the first end 11 to the second end 12; when the first scraping plate 21 scrapes only toward the second side 14, the second scraping plate 31 can be arranged in an area near the second side 14 in the zinc pot 1, and the zinc slag in the corresponding area is scraped from the first end 11 to the second end 12; when the first scraping plate 21 scrapes toward the first side 13 and the second side 14 respectively, two second scraping plates 31 can be arranged and are respectively arranged at the first side 13 and the second side 14, and the zinc slag in the area near the first side 13 and the second side 14 is scraped from the first end 11 to the second end 12.

[0069] Optionally, during operation, the bottom of the first slag skimming plate 21 may slightly contact the surface of the zinc liquid, so as to better transport the zinc slag floating on the surface of the zinc liquid from the first end 11 to the second end 12 .

[0070] In the present embodiment, a slag scraping mechanism is provided, which includes a first slag scraping plate 21 and a second slag scraping plate 31. The first slag scraping plate 21 can scrape the zinc slag in the middle area of ​​the zinc liquid to the two sides of the zinc pot 1, and the zinc slag on both sides of the zinc pot 1 will also be scraped from the first end 11 of the zinc pot 1 to the second end 12 by the second slag scraping plate 31 for aggregation, so as to facilitate the centralized removal of the zinc slag; in addition, the first slag scraping plate 21 and the second slag scraping plate 31 can be driven by machine mechanisms such as the first driving member 22 and the second driving member 32 respectively, which reduces the work intensity and is beneficial to the health of the workers.

[0071] In some embodiments, Figure 1 As shown, the first drive member 22 is fixed to a scraper 61 of a roll arm structure 6 for immersing the steel strip in the zinc bath.

[0072] Among them, the roller arm structure 6 can be a three-roller six-arm device. The three-roller six-arm device mainly plays a key role in the galvanizing process of workpieces such as strip steel. It is mainly composed of a sinking roller, a stabilizing roller, a correction roller, and six arms that support these three rollers to immerse in the zinc pot 1. It is usually called "three-roller six-arm". The working principle of this device is to achieve power transmission and conversion through the bite between the rollers. Specifically, the working principle of the three-roller six-arm device is as follows: Adjust the roller position: First, the three rollers need to be adjusted to the appropriate position to adapt to the thickness of the metal blank and the required plastic deformation. Upper roller lifting: When starting to work, the middle upper roller will rise upward, lift the metal blank and drive it to start transferring between the three rollers. Bending and pressing: After the metal blank is transferred between the three rollers, the rollers will apply pressure downward respectively to cause the metal blank to bend and deform. The height of the upper roller lifting and the pressure of the roller can be adjusted to control the plastic deformation of the metal blank. Transmission and transmission: The rollers continue to drive forward, and the metal blank is then transferred to the next set of rollers. This process can be repeated several times until the metal blank reaches the desired shape.

[0073] In the galvanizing process, the role of the scraper 61 (also called the air knife or air knife) in the three-roll six-arm device is particularly critical. The main function of the scraper 61 is to adjust and control the thickness of the galvanized layer. When the strip passes through the zinc liquid, the zinc liquid will adhere to the surface of the strip to form a zinc layer. The scraper 61 controls the thickness of the galvanized layer by blowing high-pressure gas (usually air or nitrogen) to the surface of the strip to blow away the excess zinc liquid. The working principle of the scraper 61 is to make the zinc layer on the surface of the strip reach a predetermined thickness by precisely controlling the intensity, angle and distribution of the airflow. The intensity, speed and distribution of the airflow can be achieved by adjusting the position, angle and airflow control valve of the scraper 61. The importance of the scraper 61 in the galvanizing process is that it directly affects the quality and appearance of the galvanized layer. If the galvanized layer is too thick, it will increase the cost and weight of the material, and may also affect its mechanical properties and processing properties; if the galvanized layer is too thin, it may not meet the requirements of anti-corrosion and decoration. Therefore, by precisely controlling the operation of the scraper 61, it can be ensured that the galvanized layer has a uniform and stable thickness and good appearance quality. In addition, the scraper 61 also needs to have the characteristics of wear resistance, corrosion resistance and high temperature resistance to adapt to the high temperature and corrosive environment of the zinc liquid. Therefore, the material selection, processing and maintenance of the scraper 61 are also important factors to ensure the stable operation of the galvanizing process. In short, the scraper 61 plays a vital role in the galvanizing process. It ensures that the galvanized sheet has excellent quality and performance by adjusting and controlling the thickness of the galvanized layer.

[0074] It should be noted that in the galvanizing process, after the three-roll six-arm device immerses the strip steel in the zinc liquid, the scraper 61 is generally located above the zinc liquid surface and close to the first end 11 of the zinc pot 1. At the same time, in order to ensure that the first slag removal plate 21 can perform slag removal operations better, the first driving member 22 can be fixed at the middle position of the scraper 61, and the first driving member 22 and the first slag removal plate 21 can move together with the scraper 61. In addition, the output shaft of the first driving member 22 is connected to the first slag removal plate 21 and can drive the first slag removal plate 21 to swing around the output shaft on the zinc liquid surface, so that the zinc slag located in the middle area of ​​the zinc liquid surface can be removed to the first side 13 or the second side 14.

[0075] Optionally, the first driving member 22 is a motor, which can rotate forward and reverse, so as to drive the first scraping plate 21 to swing.

[0076] This embodiment combines the first scraping plate 21 and the first driving member 22 with the original equipment (scraper 61), which has the characteristics of reasonable layout and small process changes, and can reduce production costs. In addition, the first scraping plate 21 uses a swinging action to continuously scrape the zinc slag floating in the middle area of ​​the zinc liquid surface to the first side 13 and the second side 14, which can improve work efficiency.

[0077] In some embodiments, Figure 1 and Figure 2 As shown, the end of the second slag scraping plate 31 close to the first side 13 or the second side 14 during the slag scraping process is defined as the adjacent end, and the end of the second slag scraping plate 31 away from the first side 13 or the second side 14 during the slag scraping process is defined as the distal end; wherein the adjacent end and the distal end are staggered in the second direction Z, and the adjacent end is closer to the first end 11 than the distal end during the slag scraping process. The above structural design can form an angle α between the second slag scraping plate 31 and the first direction X.

[0078] Optionally, the angle α has a value range of 25°≤α≤75°.

[0079] Optionally, the adjacent end of the second slag plate 31 is arranged close to the inner wall of the zinc pot 1, and there is a gap between the two, which is mainly to ensure that the second slag plate 31 does not interfere with the zinc pot 1 during the slag removal operation, and the gap does not allow zinc slag to pass through it.

[0080] This embodiment adopts a design in which an angle is formed between the second slag scraping plate 31 and the first direction X, which can prevent zinc slag from escaping from the far end of the second slag scraping plate 31 due to excessive accumulation during the slag scraping process. This design can optimize the slag scraping effect of the second slag scraping plate 31 and improve work efficiency.

[0081] In some embodiments, Figure 1 and Figure 2 As shown, the slag removal device also includes a frame 5, which is fixedly arranged relative to the zinc pot 1. The frame 5 can serve as a supporting structure of the entire slag removal device, and the second driving member 32 can be installed on the frame 5.

[0082] Optionally, the second driving member 32 is a two-axis displacement platform, and the output end of the two-axis displacement platform is connected to the second slag plate 31 and can drive the second slag plate 31 to move along the first direction X and the third direction Y; wherein the third direction Y is perpendicular to the zinc liquid surface.

[0083] Exemplarily, the second driving member 32 includes a second horizontal sliding portion 321 and a second vertical lifting portion 322, the second horizontal sliding portion 321 and the frame 5 are connected by a sliding matching structure of a slide groove and a slide rail, and the second horizontal sliding portion 321 can slide back and forth on the frame 5 along the first direction X driven by a motor and a chain transmission mechanism; the second vertical lifting portion 322 is fixed on the second horizontal sliding portion 321, the second vertical lifting portion 322 can be a telescopic cylinder and its output end can reciprocate along the third direction Y; the second scraping plate 31 is fixedly connected to the output end of the second vertical lifting portion 322, and the second scraping plate 31 can be driven to reciprocate along the first direction X by the second horizontal sliding portion 321, and can be driven to reciprocate along the third direction Y by the second vertical lifting portion 322. Based on the above structure, the working process of the second slag scraping plate 31 is as follows: the initial position of the second slag scraping plate 31 can be above the area of ​​the first side 13 or the second side 14 close to the first end 11. During operation, the second vertical lifting portion 322 drives the second slag scraping plate 31 to move downward along the third direction Y and slightly immerses the bottom of the second slag scraping plate 31 into the zinc liquid. Then, the second horizontal sliding portion 321 drives the second slag scraping plate 31 to move along the first direction X from the first end 11 toward the second end 12 to scrape the zinc slag to the gathering area close to the second end 12. Then, the second vertical lifting portion 322 drives the second slag scraping plate 31 to move upward along the third direction Y and separates the bottom of the second slag scraping plate 31 from the zinc liquid surface. Then, the second horizontal sliding portion 321 drives the second slag scraping plate 31 to move from the second end 12 toward the first end 11 to the initial position along the first direction X.

[0084] Optionally, there are two second slag-scraping plates 31, and the two second slag-scraping plates 31 are arranged opposite to each other along the second direction Z, that is, one of the two second slag-scraping plates 31 acts on the area close to the first side 13 of the zinc pot 1, and the other second slag-scraping plate 31 acts on the area close to the second side 14 of the zinc pot 1; it should be noted that the two second slag-scraping plates 31 do not interfere with the zinc pot 1 and the roller arm structure 6 when performing slag-scraping operations. Accordingly, there are two second driving members 32, and the two second driving members 32 drive the two second slag-scraping plates 31 to move in a one-to-one correspondence.

[0085] In this embodiment, the second driving member 32 is configured as a two-axis displacement platform, which can drive the second scraping plate 31 to complete the movement in the first direction X and the third direction Y, so that the second scraping plate 31 can work in a cycle and quickly complete the scraping operation. The above structure uses mechanical equipment instead of manual labor, which can improve work efficiency and reduce the labor intensity of workers.

[0086] In some embodiments, Figure 1 and Figure 3 As shown, the slag removal device also includes a slag scooping mechanism, which is used in conjunction with the slag scraping mechanism. After the slag scraping mechanism gathers the zinc slag in the area near the second end 12 of the zinc pot 1, the zinc slag in the area can be scooped out by the slag scooping mechanism.

[0087] Specifically, the slag scooping mechanism includes a slag scooping bucket 41 and a third driving member 42 . The slag scooping bucket 41 can be driven by the third driving member 42 and can scoop out the zinc slag accumulated in the zinc pot 1 near the second end 12 .

[0088] Optionally, there are two slag buckets 41, which are arranged opposite to each other along the second direction Z; the two slag buckets 41 can move toward each other and close together to scoop up the zinc slag and confine it inside the two slag buckets 41. It should be understood that the two slag buckets 41 can also move away from each other and open to pour out the zinc slag inside.

[0089] Optionally, the inner bottom surface of the slag bucket 41 can be designed as an inclined surface, so that after the two slag buckets 41 are opened, the zinc slag can roll out along the inclined surface by its own gravity.

[0090] Optionally, the slag removal device further comprises a frame 5 , which is fixedly arranged relative to the zinc pot 1 . The frame 5 can serve as a supporting structure of the entire slag removal device, and the third driving member 42 can be installed on the frame 5 .

[0091] Optionally, the third driving member 42 is a three-axis displacement platform, and the output end of the three-axis displacement platform is connected to the slag bucket 41 and can drive the slag bucket 41 to move along the first direction X, the second direction Z and the third direction Y; wherein the third direction Y is perpendicular to the zinc liquid surface.

[0092] Exemplarily, the third driving member 42 includes a third longitudinal translation portion 421, a third vertical lifting portion 422 and a third lateral translation portion 423. The third longitudinal translation portion 421 and the frame 5 are connected by a sliding matching structure of a slide groove and a slide rail, and the third longitudinal translation portion 421 can slide back and forth along the first direction X on the frame 5 driven by the motor and the chain transmission mechanism; the third vertical lifting portion 422 is fixed on the third longitudinal translation portion 421, and the third vertical lifting portion 422 can be a telescopic cylinder and its output end can reciprocate along the third direction Y; the third lateral translation portion 423 is fixed on the third longitudinal translation portion 421. At the output end of the three vertical lifting parts 422, the third lateral translation part 423 can be a bidirectional lead screw. The bidirectional lead screw is a mechanical transmission device in which two sections of threads with different rotation directions are made on a lead screw. Specifically, one section is a right-handed thread and a right-handed nut is screwed on it, and the other section is a left-handed thread and a left-handed nut is screwed on it. The right-handed nut and the left-handed nut are respectively connected to a slag bucket 41. When the bidirectional lead screw rotates, the two slag buckets 41 will quickly approach or separate with the right-handed nut and the left-handed nut, thereby realizing the two slag buckets 41 moving toward or away from each other in the second direction Z. Based on the above structure, the working process of the slag bucket 41 is as follows: the initial positions of the two slag buckets 41 can be respectively above the area of ​​the first side 13 close to the second end 12 and above the area of ​​the second side 14 close to the second end 12, and the two slag buckets 41 are in an open state. When working, the third vertical lifting part 422 drives the two slag buckets 41 to move downward along the third direction Y and immerse the bottoms of the two slag buckets 41 into the zinc liquid, and then the third horizontal translation part 423 drives the two slag buckets 41 to move toward each other and close together to limit the zinc slag. Between the two slag buckets 41, the third vertical lifting part 422 then drives the two slag buckets 41 to move upward along the third direction Y and separate the two slag buckets 41 from the zinc liquid surface, and then the third longitudinal translation part 421 drives the two slag buckets 41 and the zinc slag therein to move outside the zinc pot 1 along the first direction X. After reaching the zinc slag collection position, the third transverse translation part 423 drives the two slag buckets 41 to move back to each other and open to pour out the zinc slag, and finally the third longitudinal translation part 421 drives the two slag buckets 41 to move to the initial position along the first direction X.

[0093] Furthermore, the slag scooping mechanism also includes a collecting portion 43, which can be placed at a zinc slag collecting position outside the zinc pot 1. The collecting portion 43 can be used to hold the zinc slag scooped out by the slag scooping bucket 41, and the zinc slag can be processed uniformly after being collected.

[0094] Optionally, the collecting portion 43 may be a tray or a basket with an opening at the top.

[0095] The present embodiment provides a slag scooping mechanism, which can be used in conjunction with the slag scraping mechanism to quickly remove the zinc slag accumulated by the slag scraping mechanism out of the zinc pot 1 and collect the zinc slag in the collecting portion 43 for subsequent unified processing.

[0096] In some embodiments, Figure 2 and Figure 3 As shown, the first slag scraping plate 21, the second slag scraping plate 31 and the slag scoop 41 are all provided with holes through which the zinc liquid can pass.

[0097] In this embodiment, holes are designed on the first slag scraping plate 21, the second slag scraping plate 31 and the slag scoop 41, which can be used for the circulation of zinc liquid during the slag scraping and scooping process, thereby reducing the impact on the flow of zinc liquid and further reducing the impact on the galvanizing process.
