Description

Technical Field

[0001] The present application relates to the field of galvanizing, and in particular to a slag cleaning device for a galvanizing pool. Background Art

[0002] Hot-dip galvanizing is an effective method for metal corrosion protection, primarily used on metal structures in various industries. It involves immersing derusted steel components in molten zinc at approximately 500 degrees Celsius, depositing a zinc layer on the surface of the steel components to prevent corrosion.

[0003] During the hot-dip galvanizing process on steel components, zinc slag is generated and floats on the surface of the molten zinc solution, which in turn affects the subsequent galvanizing of the steel components. In the related art, a reciprocating scoop net is usually set on the galvanizing pool to clean the slag.

[0004] With regard to the above-mentioned related technologies, the inventors believe that when using a scoop net to clean slag, the scoop net tends to float on the surface of the zinc liquid, and the slag can only be pushed to one side of the galvanizing pool and then salvaged and collected. This slag cleaning method has a low degree of automation and is inconvenient. Summary of the Invention

[0005] In order to facilitate the salvage of scum, the present application provides a scum cleaning device for a galvanizing pool.

[0006] The present application provides a slag cleaning device for a galvanizing pool, which adopts the following technical solution:

[0007] A slag cleaning device for a galvanizing pool, comprising:

[0008] The pool body is provided with a frame;

[0009] A stirring mechanism, comprising a stirring assembly and a stirring drive, wherein the stirring assembly is inserted into the interior of the pool body, and the stirring drive is mounted on the frame and is used to drive the stirring assembly to rotate so as to generate a vortex inside the pool body;

[0010] The collecting mechanism includes a collecting filter box and a collecting filter cartridge. A scum inlet is provided on the top of the collecting filter box. The collecting filter box is located above the stirring assembly and is installed on the stirring drive member. The collecting filter box is detachably installed on the outer wall of the collecting filter box. A collecting trough connected to the scum inlet is provided on the collecting filter box.

[0011] By adopting the above technical solution, when it is necessary to collect scum, the stirring assembly, the collection filter box and the collection filter box are inserted into the surface of the galvanizing liquid. The stirring drive will drive the stirring assembly and the collection mechanism to rotate synchronously. When the stirring assembly rotates at high speed, a vortex will be generated, thereby generating suction.

[0012] The floating scum moves towards the center of the vortex under the action of the vortex, and moves to the bottom of the pool under the suction of the vortex. While moving to the bottom of the pool, the scum will enter the collection aluminum box through the scum inlet.

[0013] Because the collection filter box rotates synchronously with the stirring assembly, the scum inside the collection box is drawn into the collection trough of the collection filter box by centrifugal force and adheres to the trough wall, where it is collected. Finally, the collection filter box can be removed and the scum can be poured out. Compared to manual fishing with a scoop net, the above structure is more automated and more convenient for fishing scum.

[0014] Optionally, the collection mechanism further includes a valve assembly, and the valve assembly is arranged on the collection filter box to limit the scum entering the collection trough.

[0015] By adopting the above technical solution, after the scum enters the collection filter box, it can only move to the bottom of the pool body under the action of the vortex suction. However, since there is no opening at the bottom of the collection filter box for the scum to pass through, and the collection box generates centrifugal force when it rotates, the scum can only enter the aggregate trough. The setting of the valve assembly allows the scum to enter the aggregate trough only from the notch and cannot escape from the aggregate trough, thereby reducing the risk of the scum entering the aggregate trough and then escaping from the aggregate trough, thereby improving the scum cleaning effect.

[0016] Optionally, the valve assembly includes a plurality of elastic valve plates and a plurality of limit plates, the plurality of elastic valve plates are circumferentially spaced at the notch of the aggregate trough and cover the notch of the aggregate trough, the limit plate is arranged between two adjacent elastic valve plates, the limit plate is located on the side of the elastic valve plate close to the notch of the aggregate trough, and the two adjacent elastic valve plates are both in contact with the limit plate.

[0017] By adopting this technical solution, when scum enters the aggregate trough under the action of centrifugal force, the multiple elastic valve plates, under the influence of centrifugal force and the impact of molten zinc, open the notch of the aggregate trough, allowing the scum to enter the trough. Because the limit plate is located between two adjacent elastic valve plates, the risk of the elastic valve plates opening due to the impact force within the aggregate trough is reduced, thereby reducing the risk of scum in the aggregate trough escaping from the notch.

[0018] Optionally, the collecting filter box is provided with a slag outlet connected to the aggregate trough, the slag outlet is provided with a cover plate, and the trough wall of the aggregate trough is provided with a guiding slope for facilitating the concentration of slag at the slag outlet.

[0019] By adopting the above technical solution, when the collection filter box comes out of the pool body, the scum in the collection trough will be accumulated at the slag outlet under the action of the guiding slope. Then the cover plate can be opened to clean out the slag accumulated at the slag outlet, thereby making it more convenient to clean the scum in the collection filter box.

[0020] Optionally, the stirring assembly includes a rotating shaft, a stirring rod and a stirring rod seat, the rotating shaft is mounted on the stirring drive member, the stirring rod seat is connected to the rotating shaft, and the stirring rod is mounted on the stirring rod seat along the radial direction of the rotating shaft.

[0021] By adopting this technical solution, the agitation drive element drives the rotating shaft, and the agitation rod seat mounted on the rotating shaft also rotates synchronously. This allows the length of the agitation rod extending from the agitation rod seat to be adjusted according to the size of the galvanizing bath. Furthermore, it can generate vortices of varying sizes, thereby attracting scum farther from the vortex center into the collection filter.

[0022] Optionally, the stirring mechanism also includes a driving gear, a driven gear and a rotating drive member, the driven gear is rotatably mounted on the stirring rod seat, an arc-shaped sliding groove is provided on the driven gear, a limiting column is provided on the stirring rod and inserted into the arc-shaped sliding groove, a telescopic groove for the stirring rod to slide is provided on the stirring rod seat, the driving gear is meshed with the driven gear, and the rotating drive member drives the driving gear to rotate so that the stirring rod slides radially along the rotating shaft.

[0023] By adopting the above technical solution, the rotating driving member drives the driving gear to rotate, and the driving gear drives the driven gear to rotate. When the driven gear rotates, the stirring rod can only move along the radial direction of the rotating shaft under the limitation of the limiting column, the arc-shaped sliding groove and the telescopic groove, thereby making the stirring rod more stable during telescopic movement.

[0024] Optionally, a guide sleeve is provided at the notch of the aggregate trough to facilitate the slag to enter the aggregate trough.

[0025] Optionally, the radial diameter of the guide sleeve gradually decreases along the rotating shaft.

[0026] By adopting the above technical solution, when the collection filter box is rotating, the scum can enter the aggregate trough more conveniently under the guidance of the guide sleeve; since the diameter of the guide sleeve gradually decreases along the radial direction of the rotating shaft, after the collection filter box stops rotating, the scum will float to the top of the aggregate trough, thereby reducing the risk of the scum escaping from the aggregate trough through the guide sleeve.

[0027] Optionally, the collection mechanism further includes a guide sleeve provided on the collection filter box to facilitate the scum to enter the interior of the collection filter box, and the diameter of the guide sleeve gradually decreases along the direction in which the scum enters the collection filter box.

[0028] By adopting the above technical solution, since the vortex diameter becomes smaller as it approaches the bottom of the pool body, the setting of the guide sleeve is more in line with the shape of the vortex, and the scum can enter the collection filter box by fitting the inside of the guide sleeve, reducing the risk of scum floating around in the vortex and making it easier for the scum to enter the collection filter box.

[0029] Optionally, the slag cleaning device of the galvanizing pool also includes a flushing mechanism for cleaning the stirring mechanism, the flushing mechanism includes a water outlet pipe and a high-pressure nozzle, the water outlet pipe is arranged on the frame, and there are multiple high-pressure nozzles, and the multiple high-pressure nozzles are arranged at intervals on the water outlet pipe.

[0030] By adopting the above technical solution, when cleaning the scum, some smaller scum can easily pass through the collection filter box and get stuck in the arc-shaped sliding groove, thereby affecting the extension and retraction of the stirring rod. After the scum cleaning is completed, the high-pressure nozzle can flush the arc-shaped sliding wipe, thereby flushing away the scum blocked in the arc-shaped sliding groove, making the extension and retraction of the stirring rod smoother.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The stirring drive drives the stirring rod to rotate, generating a vortex in the pool body, which absorbs the scum into the collection filter box. The scum enters the collection filter box for storage under the centrifugal force generated by the rotation of the collection filter box. The cleaning of the scum is more automated and more convenient.

[0033] 2. When scum enters the aggregate trough under the action of centrifugal force, multiple elastic valve plates will open the notch of the aggregate trough under the impact of centrifugal force and zinc liquid. When force is applied to the elastic valve plates from inside the aggregate trough, two adjacent elastic valve plates cannot open due to the action of the limit plate and remain closed, thereby reducing the risk of scum escaping from the aggregate trough;

[0034] 3. The stirring rod can be extended and retracted from the telescopic slot along the radial direction of the rotating shaft. On the one hand, the length of the stirring rod extending from the stirring rod seat can be adjusted according to the size of the galvanizing pool; on the other hand, vortices of different sizes can be generated, and the scum at a position far away from the center of the vortex can also be adsorbed into the collection filter box.

[0044] The following is combined with Figure 1-8 This application is described in further detail.

[0045] The present application discloses a slag cleaning device for a galvanizing pool. Figure 1 and Figure 2 The scum cleaning device for a galvanizing bath comprises a bath body 1, an agitating mechanism 2, a collecting mechanism 3, and a flushing mechanism 4. A frame 5 is slidably mounted on the top of the bath body 1, upon which the agitating mechanism 2 and flushing mechanism 4 are mounted. The collecting mechanism 3 is mounted on the agitating mechanism 2. The agitating mechanism 2 is inserted into the bath body 1 to stir the water, generating a vortex within the bath body 1. This vortex draws scum floating on the surface of the liquid in the bath body 1 into the collecting mechanism 3 for storage. The flushing mechanism 4 flushes the agitating mechanism 2, thereby removing any scum adhering to it without affecting the next operation of the agitating mechanism 2.

[0046] Reference Figure 1 In this embodiment, a rectangular tank body 1 is used as an example. A partition plate 11 is integrally formed within the tank body 1. The partition plate 11 divides the tank body 1 into a galvanizing tank body 12 and a rinsing tank body 13 along its length. The frame 5 slides back and forth along the length of the tank body 1. When the agitator 2 needs to be rinsed, the frame 5 moves to the rinsing tank body 13, thereby reducing the risk of rinsing water entering the galvanizing tank body 12 and affecting the concentration of the galvanizing liquid.

[0047] Reference Figure 1 and Figure 2 The frame 5 includes two vertical rods 51 and a cross bar 52 connecting the two vertical rods 51. The cross bar 52 is located at the top of the two vertical rods 51 and is integrally formed with the two cross bars 52. The two cross bars 52 are respectively located at the top of the two pool walls in the length direction of the pool body 1.

[0048] Among them, a screw motor 6 that drives the frame 5 to slide is installed on the pool wall at the top of the pool body 1. The screw motor 6 refers to a motor with a screw installed on the output shaft of the motor. The screw of the screw motor 6 is extended along the length direction of the pool body 1. The top of the pool body 1 is integrally formed with a screw rotating seat 14 for installing the screw in the screw motor 6. There are two screw rotating seats 14, and the two screw rotating seats 14 are located on both sides of the length direction of the pool body 1. The cross bar 52 is located between the two screw rotating seats 14, and the screw passes through the vertical rod 51 and is threadedly engaged with the vertical rod 51. The side of the vertical rod 51 facing away from the cross bar 52 abuts against the pool body 1, and then the entire frame 5 slides along the length direction of the pool body 1 under the drive of the screw motor 6. In order to ensure the stability of the frame 5 during movement, two screw motors 6 are provided in this embodiment, and the two screw motors 6 correspond one to one to the two vertical rods 51.

[0049] Reference Figure 1 and Figure 2A cylinder 53 is installed at the bottom of the cross bar 52 by bolts, and a mounting plate 54 is fixedly installed on the telescopic rod of the cylinder 53. The stirring mechanism 2 is installed on the mounting plate 54. The stirring mechanism 2 is driven by the cylinder 53 to rise and fall in the vertical direction, and will not interfere with the partition when moving from the galvanizing tank body 12 to the flushing tank body 13.

[0050] Reference Figure 2 and Figure 3 The stirring mechanism 2 includes a stirring assembly 21, a stirring drive 22, a driving gear 23, a driven gear 24, and a rotating drive 25. The stirring drive 22 is mounted on the top of the mounting plate 54. The stirring assembly 21 is mounted on the stirring drive 22 and rotates at high speed within the galvanizing tank 12 to generate a vortex. The driving gear 23 is mounted on the rotating drive 25, and the driven gear 24 is rotatably mounted on the stirring assembly, and the driving gear 23 and the driven gear 24 are meshed with each other. The driven gear 24 rotates to drive the stirring assembly 21 to contract, thereby controlling the size of the generated vortex.

[0051] The stirring assembly 21 includes a rotating shaft 211, a stirring rod 212, and a stirring rod seat 213. The driving portion of the stirring drive member 22 passes through the mounting plate 54 and is located at the bottom of the mounting plate 54. The rotating shaft 211 is fixedly mounted to the driving portion of the stirring drive member 22. In this embodiment, the stirring drive member 22 is preferably a motor, and thus the driving portion of the stirring drive member 22 is a motor shaft. The stirring rod seat 213 is mounted on the rotating shaft 211 and rotates synchronously with the rotating shaft 211. The stirring rod 212 is mounted on the stirring rod seat 213 so as to slide radially along the rotating shaft 211.

[0052] Reference Figure 2 and Figure 3 , wherein at least two stirring rods 212 are provided, and the plurality of stirring rods 212 are evenly spaced circumferentially on the stirring rod seat 213. In this embodiment, four stirring rods 212 are preferably provided, and the following description will be made taking one stirring rod 212 as an example. The stirring rod 212 includes a sliding rod 2121 and a stirring rod 2122. The stirring rod 2122 is located on the side of the sliding rod 2121 away from the central axis of the rotating shaft 211 in the radial direction of the rotating shaft 211, and the stirring rod 2122 is located outside the stirring rod seat 213. The stirring rod 2122 extends upward on the sliding rod 2121, so that the contact area with the liquid during stirring is larger, and vortexes are generated more conveniently. In this embodiment, the sliding rod 2121 and the stirring rod 2122 are preferably formed as one piece.

[0053] Reference Figure 3 and Figure 4In this embodiment, the stirring rod base 213 is a cylindrical body. The central axis of the stirring rod base 213 coincides with the central axis of the rotating shaft 211. A telescopic slot 2131 is defined on the outer wall of the stirring rod base 213. The extending direction of the telescopic slot 2131 is aligned with the radial direction of the stirring rod base 213. The sliding rod 2121 is inserted into the telescopic slot 2131 and slides within the telescopic slot 2131 along the extending direction of the telescopic slot 2131.

[0054] A limiting column 2123 is integrally formed at the top of the sliding rod 2121, and a moving groove 2132 is opened on the groove wall at the top of the telescopic groove 2131 for the limiting column 2123 to pass through and slide. The moving groove 2132 passes through the stirring rod seat 213, and the extension direction of the moving groove 2132 is consistent with the extension direction of the telescopic groove 2131.

[0055] Reference Figure 3 and Figure 4 A rotating column 2133 is integrally formed at the top of the stirring rod base 213, and the central axis of the rotating column 2133 coincides with the central axis of the stirring rod base 213. The driven gear 24 is sleeved on the rotating column 2133 and rotates about the rotating column 2133. An arcuate sliding groove 241 is defined at the top of the driven gear 24, extending vertically through the driven gear 24.

[0056] The distance between the wall of one end of the arcuate sliding groove 241 and the central axis of the rotating post 2133 is greater than the distance between the wall of the other end of the arcuate sliding groove 241 and the central axis of the rotating post 2133. Furthermore, the arcuate sliding groove 241 is arranged on the driven gear 24 at an angle along the radial direction of the driven gear 24. The limiting post 2123 protrudes from the movable groove 2132 and is inserted into the arcuate sliding groove 241. When the driven gear 24 rotates, the limiting post 2123, constrained by the arcuate sliding groove 241 and the movable groove 2132, can only slide along the extension direction of the movable groove 2132, thereby causing the sliding rod 2121 to slide along the extension direction of the telescopic groove 2131. Since four toggle levers are provided in this embodiment, four arcuate sliding grooves 241 are also provided, with each corresponding to one of the four toggle levers.

[0057] When the limiting post 2123 abuts the wall of the arcuate sliding groove 241 near the end of the rotating post 2133, the stirring rod 212 is in a retracted state. When the limiting post 2123 abuts the wall of the arcuate groove away from the rotating post 2133, the stirring rod 212 is in a fully extended state. The rotating drive member 25 is mounted on the collection mechanism 3 via bolts, and the driving gear 23 is mounted on the driving portion of the rotating drive member 25. In this embodiment, the rotating drive member 25 is preferably a motor, and the driving portion of the rotating drive member 25 is the motor shaft.

[0058] Reference Figure 3 and Figure 4An arc-shaped connecting groove 2134 is provided on the side of the stirring rod seat 213 close to the driven gear 24. The arc-shaped connecting groove 2134 runs through the stirring rod seat 213. When the stirring rod 212 is in a retracted state, the vertical contour line of the arc-shaped sliding groove 241 coincides with the vertical contour line of the arc-shaped connecting groove 2134, so that the scum blocked in the arc-shaped sliding groove 241 can be flushed down during flushing.

[0059] A threaded hole is formed on the side of the rotating shaft 211 near the stirring rod seat 213. The side of the rotating post 2133 facing away from the stirring rod seat 213 protrudes from the driven gear 24 and is inserted into the threaded hole to be threadedly mounted on the rotating shaft 211. The tightening direction of the rotating post 2133 is the same as the rotation direction of the stirring rod seat 213. That is, the rotating post 2133 is more firmly connected to the rotating shaft 211 as the stirring rod seat 213 rotates.

[0060] Combine Figure 2 Reference Figure 5 and Figure 6 The collecting mechanism 3 includes a collecting filter box 31, a collecting filter cartridge 32, a valve assembly 33 and a guide sleeve 34. The collecting filter box 31 is located above the stirring rod 212 and is fixedly mounted on the rotating shaft 211. The collecting filter box 32 and the guide sleeve 34 are both mounted on the collecting filter box 31, and the valve assembly 33 is mounted on the collecting filter box 32 to limit the scum entering the collecting filter box 32. The scum in the vortex enters the collecting filter box 31 under the action of the guide sleeve 34, and the centrifugal force generated by the collecting filter box 31 during rotation causes the scum to pass through the valve assembly 33 and enter the collecting filter box 32. Under the action of the valve assembly 33, the scum in the collecting filter box 32 is not easily separated from the position of the valve assembly 33. The rotating drive member 25 is mounted at the bottom of the collecting filter box 31.

[0061] In this embodiment, the collecting filter box 31 is a cylindrical shell with a hollow interior. The central axis of the collecting filter box 31 coincides with the central axis of the rotating shaft 211, and the collecting filter box 31 is sleeved on the rotating shaft 211. The bottom of the collecting filter box 31 is provided with a plurality of water filter holes that are connected to the interior of the collecting filter box 31. The top of the collecting filter box 31 does not have water filter holes, but is provided with a circular scum inlet 311. The scum in the vortex can enter the interior of the collecting filter box 31 through the scum inlet 311 and cannot escape from the interior of the collecting filter box 31 when the collecting filter box 31 rotates. The galvanizing liquid will be discharged from the collecting filter box 31 through the water filter holes.

[0062] Reference Figure 5 and Figure 6 The guide sleeve 34 is arranged at the scum inlet 311 of the collection filter box 31 , and the inner diameter of the guide sleeve 34 gradually increases along the axial direction of the collection filter box 31 , thereby guiding the scum in the vortex into the collection filter box 31 .

[0063] The outer wall of the collection filter box 31 is provided with a mounting slot 312, which communicates with the interior of the collection filter box 31. The collection filter box 31 is inserted into the mounting slot 312 and mounted to the collection filter box 31 via bolts. Multiple collection filter boxes 32 are provided, and the multiple collection filter boxes 32 are evenly arranged on the outer wall of the collection filter box 31. In this embodiment, four collection filter boxes 32 are preferably provided, and the four collection filter boxes 32 have the same structure. Four mounting slots 312 are also provided, and the four mounting slots 312 correspond one-to-one to the four collection filter boxes 32. The following description uses one collection filter box 32 as an example.

[0064] Reference Figure 6 and Figure 7 The collecting filter box 32 is provided with a collecting trough 321 for storing scum on one side close to the rotating shaft 211, and the collecting trough 321 is communicated with the interior of the collecting filter box 31. Each trough wall and trough bottom of the collecting trough 321 are also provided with water filtering holes, which penetrate the collecting filter box 32.

[0065] The bottom of the collection filter box 32 is provided with a slag outlet 322, which is covered by a cover plate 323 bolted to the collection filter box 32. The cover plate 323 can then be removed to pour the slag from the collection trough 321 out of the slag outlet 322. The bottom of the collection trough 321 is provided with a guide slope 3211, which slopes vertically from top to bottom, away from the notch of the collection trough 321. After the collection filter box 32 is removed from the galvanizing solution, the slag will accumulate at the slag outlet 322 due to the guidance of the guide slope 3211.

[0066] A guide sleeve 324 is integrally formed at the opening of the trough 321. The guide sleeve 324 extends toward the bottom of the trough 321, and its inner diameter gradually decreases as it extends toward the bottom of the trough 321. The valve assembly 33 is mounted on the side of the guide sleeve 324 with the smaller inner diameter.

[0067] Reference Figure 6 and Figure 8 The valve assembly 33 includes a plurality of elastic valve discs 331 and a plurality of limiting plates 332. The plurality of elastic valve discs 331 are evenly spaced circumferentially on the guide sleeve 324 and cover the opening of the guide sleeve 324 with a smaller inner diameter. The limiting plate 332 is disposed on the side of the elastic valve disc 331 facing away from the bottom of the trough 321. The limiting plate 332 is located between two adjacent elastic valve discs 331, and each of the two adjacent elastic valve discs 331 abuts against the limiting plate 332. The plurality of limiting plates 332 are also evenly spaced circumferentially on the guide sleeve 324, with each limiting plate 332 corresponding to a position between two adjacent elastic valve discs 331.

[0068] The centrifugal force generated by the collection filter box 31 during rotation causes the scum to contact the galvanizing solution, impacting the elastic valve disc 331. This in turn causes the elastic valve disc 331 to deform elastically. The multiple elastic valve discs 331, when approaching each other, tilt toward the bottom of the trough 321, allowing the scum to enter the trough 321. However, under the action of the limit plate 332, when the elastic valve disc 331 is impacted outward by the trough 321, the multiple elastic valve discs 331 abut against the limit plate 332, preventing them from opening. This reduces the risk of scum escaping the trough 321. In this embodiment, four elastic valve discs 331 are preferably provided, and four limit plates 332 are provided, each of which is fixedly mounted on the guide sleeve 324.

[0069] Reference Figure 2 The flushing mechanism 4 includes a water outlet pipe 41, a high-pressure nozzle 42 and a water inlet pipe 43. The water outlet pipe 41 is a hard water pipe in a circular shape, and the water outlet pipe 41 is installed on two vertical rods 51. The collecting filter box 31 and the toggle rod seat rotate around the inner ring of the water outlet pipe 41 during the movement in the vertical direction. The high-pressure nozzle 42 is installed on the inner side of the water outlet pipe 41, and the high-pressure nozzle 42 is tilted downward. There are multiple high-pressure nozzles 42, and the multiple high-pressure nozzles 42 are arranged at intervals on the inner side of the water outlet pipe 41, so that flushing in multiple directions can be performed. One end of the water inlet pipe 43 is connected to and communicated with the water outlet pipe 41, and the other end is connected to the water source.

[0070] The implementation principle of the slag cleaning device for a galvanizing pool in an embodiment of the present application is as follows: after the galvanizing of the workpiece is completed, the workpiece is salvaged, and then the screw motor 6 drives the frame 5 to move to the top of the galvanizing pool body 12, and the oil cylinder 53 drives the stirring component 21, the collection filter box 31 and the guide sleeve 34 to descend below the liquid level of the galvanizing liquid. At this time, the stirring component 21 is still a certain distance from the bottom of the galvanizing pool body 12, that is, the stirring component 21 is located in the middle position of the depth of the galvanizing liquid, and the stirring drive component is located above the liquid level of the galvanizing liquid.

[0071] The agitation drive element rotates the rotating shaft 211, and the agitation rod 212 rotates synchronously with the rotating shaft 211. When the agitation drive element reaches a certain speed, a vortex is generated within the galvanizing tank 12, which then sucks all the surrounding scum into the vortex. The rotation drive element 25 can drive the driving gear 23 to rotate, which in turn drives the driven gear 24, thereby causing the agitation rod 212 to extend and retract to adjust the agitation diameter and control the size of the vortex.

[0072] The scum enters the collection filter box 31 under the action of the vortex. Since there is no outlet for the scum to flow out at the bottom of the collection filter box 31, and the collection filter box 31 is also rotating at a high speed, the scum that enters the collection filter box 31 can pass through the valve assembly 33 and enter the collection tank 321 under the action of the centrifugal force generated by the rotation of the collection filter box 31.

[0073] When the scum is exposed to the galvanizing solution, it impacts the elastic valve disc 331, causing it to deform elastically. The side of the multiple elastic valve discs 331 that is close to each other tilts toward the bottom of the trough 321, allowing the scum to enter the trough 321. However, under the action of the limit plate 332, when the elastic valve disc 331 is impacted outward by the trough 321, the side of the multiple elastic valve discs 331 that is close to each other abuts against the limit plate 332, preventing it from opening.

[0074] After the scum is removed, the oil cylinder 53 drives the stirring assembly to rise above the galvanizing liquid surface. The screw motor 6 then drives the frame 5 to move above the flushing tank 13. As the oil cylinder 53 drives the stirring mechanism 2 and the collection mechanism 3 up and down, the high-pressure nozzle 42 flushes the scum adhering to the bottom and upper walls of the collection trough 321 toward the scum outlet 322. Simultaneously, the high-pressure nozzle 42 also flushes the stirring assembly 21, removing any scum remaining within the arcuate sliding groove 241. After flushing, the driving member 25 rotates to retract the stirring rod 212. Finally, the collection filter box 32 is removed to pour out the scum inside. This cycle continues.

[0075] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
