Before describing the embodiments of the present application, the reasons for the problem that the zinc slag on the liquid surface of the zinc liquid is difficult to accumulate and clean in the related art are analyzed, and the technical scheme of the embodiments of the present application is obtained through reasonable analysis.

In the related art, a hot galvanizing process is a common metal corrosion prevention method, and the principle is to coat a zinc layer on the surface of a metal to prevent the metal from being oxidized and corroded. This process is also called hot dip galvanization or hot dip galvanization, and is a technique of immersing a metal such as a steel strip in a molten liquid metal or alloy to obtain a plated layer. In particular, the process of hot galvanizing can be divided into three main parts, pretreatment, hot dip galvanizing and post-treatment. The main purpose of pretreatment is to remove greasy dirt, dust and rust on the surface of workpieces such as strip steel, and the like, and the pretreatment generally comprises degreasing (if needed), pickling, deweighting, water washing, plating assistance, drying and the like. These steps ensure that the workpiece is in a clean and activated state prior to hot dip galvanization. In the hot dip galvanization stage, the pre-treated workpiece is immersed in a molten zinc bath at a temperature of about 450 ℃. In this process, zinc reacts with and diffuses from the metal surface to form a uniform, dense zinc-iron alloy coating. The coating has excellent corrosion resistance and can provide durable corrosion protection in the fields of outdoor equipment, building structures, pipelines, power equipment and the like. In the post-treatment stage, the galvanized workpiece is subjected to operations such as cooling, passivation and the like so as to ensure that the plating layer on the surface of the galvanized workpiece has optimal performance. Wherein, the cooling usually adopts an air cooling or water cooling mode to quickly convert the surface liquid zinc into solid crystalline zinc. And passivation is to prevent white rust of the workpiece during long-term storage and transportation. In general, the hot galvanizing process is an effective metal corrosion prevention method, and the plating layer is uniform and compact and has strong corrosion resistance, so that the service life of a metal product can be greatly prolonged. Meanwhile, the process has the advantages of simple and convenient operation, low cost and the like, and is widely applied to various fields.

In the hot galvanizing process of the strip steel, because zinc materials are continuously supplemented in the zinc pot, meanwhile, the zinc materials can also bring a lot of impurities into the zinc pot, a lot of scum (zinc slag) can be generated on the zinc liquid surface, and if the scum is not cleaned in time, the galvanization quality of the strip steel surface can be greatly influenced. At present, zinc slag in a zinc pot is manually removed by means of a manual tool, the zinc slag is not easy to gather together in the manual zinc slag removing process, and the operation difficulty is high.

The application provides a slag removing device which comprises a slag removing mechanism, wherein the slag removing mechanism comprises a first slag removing plate and a second slag removing plate, in the slag removing process, the first slag removing plate is driven by a first driving piece to remove zinc slag positioned in the middle area of the liquid level of zinc liquid to two sides of a zinc pot, and the second slag removing plate is driven by a second driving piece to remove zinc slag close to two sides of the zinc pot from one end to the other end so as to be beneficial to centralized cleaning of the zinc slag, thereby solving the technical problems that zinc slag in the zinc pot is difficult to collect and is unfavorable to clean in the prior art.

Technical solutions of embodiments of the present application will be described in detail below with reference to the accompanying drawings, and technical features of different embodiments of the present application described below may be combined with each other as long as they do not collide with each other.

In the process of skimming, the primary function of the first skimming plate 21 is to skim the zinc dross floating in the middle area of the liquid level of the zinc liquid in the second direction Z toward the side of the zinc pot 1. Specifically, at least in the case of performing the slag removing operation, the first slag removing plate 21 is disposed in the zinc pot 1 near the first end 11, and the first slag removing plate 21 may be driven by the first driving member 22 and remove the zinc slag located in the middle area of the zinc liquid surface to the first side 13 and/or the second side 14, that is, the first slag removing plate 21 may remove the zinc slag in the middle area of the zinc liquid surface to the first side 13 only, or the first slag removing plate 21 may remove the zinc slag in the middle area of the zinc liquid surface to the second side 14 only, or the first slag removing plate 21 may remove the zinc slag in the middle area of the zinc liquid surface to the first side 13 and the second side 14, respectively.

Alternatively, the first slag runner 21 may be positioned in a central region of the liquid level of the zinc so that the first slag runner 21 is capable of slag runner to both the first side 13 and the second side 14.

Optionally, the bottom of the first slag-removing plate 21 may be slightly higher than the liquid level of the zinc liquid during operation, so that under the condition that the first slag-removing plate 21 can remove zinc slag, the influence of the first slag-removing plate 21 on the zinc liquid caused by larger fluctuation can be reduced, and the influence on the galvanization process of the strip steel can be avoided.

In the process of skimming, the second skimming plate 31 mainly aims to collect zinc dross floating on two sides of the liquid level of the zinc from the first end 11 near the zinc pot 1 to a collecting area near the second end 12 so as to facilitate centralized cleaning. Specifically, at least in the case of performing the skimming work, the second skimming plate 31 is disposed in the zinc pot 1 near the first side 13 and/or the second side 14, and the second skimming plate 31 can be driven by the second driving member 32 and skim the zinc dross near the first side 13 and/or the second side 14 from the first end 11 to the second end 12. The second slag-removing plate 31 is used in combination with the first slag-removing plate 21, and when the first slag-removing plate 21 is used to remove slag from the first side 13, the second slag-removing plate 31 is disposed in the zinc pot 1 at a position near the first side 13 and the second side 14, and when the first slag-removing plate 21 is used to remove slag from the second side 14, the second slag-removing plate 31 is disposed in the zinc pot 1 at a position near the second side 14 and the second end 12 is removed from the first side 11, and when the first slag-removing plate 21 is used to remove slag from the first side 13 and the second side 14, the second slag-removing plate 31 is disposed at the first side 13 and the second side 14, respectively, and the zinc slag in the position near the first side 13 and the second side 14 is removed from the first end 11 to the second end 12.

Alternatively, the bottom of the first slag-off plate 21 may be in slight contact with the liquid level during operation so as to be able to better transport the zinc slag floating on the liquid level from the first end 11 to the second end 12.

In this embodiment, a slag removing mechanism is provided, the slag removing mechanism includes a first slag removing plate 21 and a second slag removing plate 31, the first slag removing plate 21 can remove zinc slag in the middle area of zinc liquid to two sides of the zinc pot 1, and zinc slag at two sides of the zinc pot 1 is collected by the first end 11 of the zinc pot 1 of the second slag removing plate 31 to the second end 12 so as to facilitate centralized removal of zinc slag, in addition, the first slag removing plate 21 and the second slag removing plate 31 can be driven by a first driving member 22, a second driving member 32 and other machine mechanisms respectively, so that the working strength is reduced, and the physical health of workers is facilitated.

In some embodiments, as shown in fig. 1, the first drive member 22 is secured to a doctor blade 61 of a roller arm structure 6 for immersing the strip in a molten zinc.

The roller arm structure 6 may be a three-roller six-arm device, which mainly plays a key role in the galvanization process of workpieces such as strip steel, and mainly comprises a sinking roller, a stabilizing roller, a correcting roller and six support arms for supporting the three rollers to be immersed in the zinc pot 1, and is commonly called as a three-roller six-arm. The working principle of the device is that the transmission and conversion of power are realized through the engagement between rollers. Specifically, the three-roller six-arm device works on the principle that the roller positions are adjusted by first, the three rollers need to be adjusted to the proper positions to accommodate the thickness of the metal blank and the required plastic deformation. And lifting the upper roller, namely lifting the middle upper roller upwards to lift the metal blank and drive the metal blank to start to be conveyed among the three rollers when the upper roller starts to work. Bending press, namely after the metal blank is conveyed between three rollers, the rollers respectively apply downward pressure to bend and deform the metal blank. The height of the upper roller lift and the pressure of the rollers can be adjusted to control the plastic deformation of the metal blank. And (3) transmission and conveying, namely continuously transmitting the rollers forwards, and conveying the metal blank to the position of the next group of rollers. This process may be repeated a number of times until the metal blank has reached the desired shape.

The role of the doctor 61 (also called air knife or air knife) in a three-roll six-arm device is particularly critical in the galvanization process. The main function of the doctor blade 61 is to adjust and control the thickness of the galvanising layer. When the strip steel passes through the zinc liquid, the zinc liquid can be attached to the surface of the strip steel to form a zinc layer. The doctor blade 61 blows off the excess zinc liquid by blowing high-pressure gas (typically air or nitrogen) against the surface of the strip, thereby controlling the thickness of the zinc layer. The doctor 61 operates on the principle that the zinc layer on the surface of the strip is brought to a predetermined thickness by precisely controlling the intensity, angle and distribution of the air flow. The intensity, speed and distribution of the air flow can be achieved by adjusting the position, angle and air flow control valve of the doctor 61. The importance of the doctor blade 61 in the galvanization process is that it directly affects the quality and appearance of the galvanization layer. If the galvanized layer is too thick, the cost and weight of the material may be increased while the mechanical properties and processability thereof may be affected, and if the galvanized layer is too thin, the requirements of corrosion resistance and decoration may not be satisfied. Therefore, by precisely controlling the operation of the doctor blade 61, it is possible to ensure that the galvanized layer has a uniform and stable thickness and good appearance quality. In addition, the doctor blade 61 is required to have wear, corrosion and high temperature resistance characteristics to accommodate the high temperature and corrosive environment of the zinc bath. Therefore, the material selection, processing and maintenance of the doctor blade 61 are also important factors to ensure a stable operation of the galvanization process. In summary, the doctor blade 61 plays a critical role in the galvanization process, which ensures that the galvanized sheet has excellent quality and performance by adjusting and controlling the thickness of the galvanization layer.

It should be noted that, in the galvanization process, after the strip steel is immersed in the zinc liquid by the three-roller six-arm device, the scraper 61 is generally located on the zinc liquid surface and near the first end 11 of the zinc pot 1, and in order to ensure that the first slag-removing plate 21 can perform better slag-removing operation, the first driving member 22 may be fixed at the middle position of the scraper 61, and the first driving member 22 and the first slag-removing plate 21 may move together with the scraper 61. In addition, the output shaft of the first driving member 22 is connected to the first slag-removing plate 21 and is capable of driving the first slag-removing plate 21 to swing around the output shaft over the zinc liquid surface so that the zinc slag located in the middle region of the zinc liquid surface can be removed to the first side 13 or the second side 14.

Alternatively, the first driving member 22 is a motor that can be rotated forward and backward so as to be capable of driving the first slag-raking plate 21 to swing.

In addition, the first slag-removing plate 21 adopts swinging motion to continuously remove the zinc slag floating in the middle area of the liquid level of the zinc liquid to the first side 13 and the second side 14, thereby improving the working efficiency.

In some embodiments, as shown in fig. 1 and 2, an end of the second slag plate 31 near the first side 13 or the second side 14 during slag skimming is defined as a proximal end, and an end of the second slag plate 31 far from the first side 13 or the second side 14 during slag skimming is defined as a distal end, wherein the proximal end and the distal end are offset in the second direction Z, and the proximal end is closer to the first end 11 than the distal end during slag skimming. The above structural design can make the second slag-raking plate 31 form an included angle alpha with the first direction X.

Alternatively, the included angle alpha has a value range of 25 DEG.ltoreq.alpha.ltoreq.75 deg.

Optionally, the adjacent end of the second slag-removing plate 31 is disposed proximate to the inner wall of the zinc pot 1 with a gap therebetween, the gap being primarily for ensuring that the second slag-removing plate 31 does not interfere with the zinc pot 1 during the slag-removing operation and the gap does not allow zinc slag to pass therethrough.

The design of forming an included angle between the second slag-removing plate 31 and the first direction X is adopted in the embodiment, so that the situation that zinc slag is accumulated more and separated from the far end of the second slag-removing plate 31 in the slag-removing process can be avoided, the slag-removing effect of the second slag-removing plate 31 can be optimized, and the working efficiency can be improved.

Based on the above structure, the second slag-removing plate 31 may be operated such that the initial position of the second slag-removing plate 31 is above the area of the first side 13 or the second side 14 near the first end 11, and when in operation, the second vertical lifting portion 322 drives the second slag-removing plate 31 to move down along the third direction Y and to slightly submerge the bottom of the second slag-removing plate 31 into the zinc liquid, then the second horizontal sliding portion 321 drives the second slag-removing plate 31 to move from the first end 11 toward the second end 12 along the first direction X so as to remove the zinc slag toward the gathering area near the second end 12, then the second vertical lifting portion 322 drives the second slag-removing plate 31 to move up along the third direction Y and to separate the bottom of the second slag-removing plate 31 from the zinc liquid surface, and then the second horizontal sliding portion 321 drives the second slag-removing plate 31 to move from the second end 12 toward the first end 11 along the first direction X to the initial position.

Optionally, the number of the second slag-removing plates 31 is two, and the two second slag-removing plates 31 are oppositely arranged along the second direction Z, namely, one second slag-removing plate 31 of the two second slag-removing plates 31 acts on the area close to the first side 13 of the zinc pot 1, and the other second slag-removing plate 31 acts on the area close to the second side 14 of the zinc pot 1, and it is noted that the two second slag-removing plates 31 do not interfere with the zinc pot 1 and the roller arm structure 6 when the slag-removing operation is performed.
