Description

Technical Field

[0001] This invention relates to the field of slag removal technology for galvanized pools, and more specifically, to a slag removal device and method for galvanized pools. Background Technology

[0002] During the galvanizing process, iron and zinc undergo a metallurgical reaction to form a zinc-iron alloy, i.e., zinc dross. This zinc dross mainly includes floating dross and bottom dross, which reduce the fluidity of the zinc bath and affect the coating quality. Therefore, dross removal from the galvanizing bath has become an important step in the field of hot-dip galvanizing technology.

[0003] Currently, the existing slag removal operations in galvanizing pools mostly use filter screens to scoop slag from the pool. This method is inefficient and affects efficiency, and the mesh of the filter screen is prone to slag leakage, resulting in insufficient slag removal and requiring repeated scooping, which affects the use of subsequent galvanizing operations.

[0004] To address the aforementioned problems, this application proposes a slag removal device and method for galvanizing tanks. Summary of the Invention

[0005] The purpose of this invention is to provide a slag removal device and method for galvanizing tanks, which can effectively solve the problems mentioned in the background art.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A slag removal device for a galvanizing tank includes: a galvanizing tank, a crossbeam, and a slide block. The slide block moves back and forth via an external transmission mechanism. A wire release box is located inside the left and right ends of the slide block and is connected to the crossbeam via a pull rope in front of it to drive it to perform slag removal operations.

[0008] The bottom front and rear sides of the cross frame are provided with side plates. The dense mesh plate and sparse mesh plate at the bottom front and rear are used to scoop out the residue inside the galvanizing tank and limit the scooped residue to achieve the effect of storage and prevent leakage.

[0009] The bottom of the side plate is equipped with a scraper for installing a dense mesh plate and a sparse mesh plate. At the bottom of the cross frame, there are two back-to-back base frames for installing a horizontal dense mesh plate and a sparse mesh plate. These, together with the vertical dense mesh plate and sparse mesh plate, form a limiting space to fix the residue in a certain area for easy retrieval operations.

[0010] The base frame and the adjacent end face of the scraper are provided with scraping edges and are connected to each other to form a seal. The scraping edge located at the lower end of the scraper is used to scrape the inner wall of the galvanizing tank so that the residue falls off and achieves the effect of fully removing the slag.

[0011] A side pipe is provided above the cross frame, which is used to blow the wind generated by the fan above the cross frame into the interior of the dense mesh plate and the sparse mesh plate after the residue is removed by the dense mesh plate and the sparse mesh plate, so as to achieve the effect of discharging the residue.

[0012] The above technical solution, which combines dense and sparse mesh plates and is vertically assembled to replace the traditional filter screen mechanism, can limit the residue between the two during slag removal operations, preventing leakage and achieving the effect of storage, which is convenient for centralized cleaning and use. Compared with the existing slag removal methods, it has the effect of high efficiency and thorough slag removal.

[0013] As a further optimization of the present invention, the left and right sides of the vertical dense mesh plate and sparse mesh plate are provided with plate mechanisms that connect the two, and are also used to scrape slag from the left and right inner walls of the galvanizing pool to facilitate retrieval.

[0014] As a further optimization of the present invention, a connecting rod that is fixed to the cross frame is provided above both the base frame and the scraper.

[0015] As a further optimization of the present invention, side frames are provided on both the front and rear sides of the cross frame, and the guide rods inside the left and right sides form a sliding connection and support effect on the side plates.

[0016] As a further optimization of the present invention, the middle interior of the side frame is provided with a transmission screw that is rotatably connected to the boss below the cross frame, and the outer side of the transmission screw is helically connected to the side plate to drive it to move back and forth.

[0017] As a further optimization of the present invention, a transmission gear shaft is rotatably installed between adjacent bosses and docked with a transmission screw. A rotary motor is provided on the outside of the rotary motor on the rear side of the cross frame, which drives the transmission gear shaft and the transmission screw to rotate through the gear mechanism at its front end.

[0018] As a further optimization of the present invention, the outer side of the boss is provided with a conduit tube that connects to the side of the side tube, and the lower end of the side tube is provided with a connecting pipe for connecting the side tube and the cross frame.

[0019] As a further optimization of the present invention, the outer side of the convex tube is a convex thick structure.

[0020] As a further optimization of the present invention, the end of the conduit is provided with a limiting strip that engages with the mounting seat inside the positioning groove on the outside of the convex tube to form a seal and limit the movement.

[0021] A method for removing slag from a galvanizing tank, applied to the slag removal device for a galvanizing tank as described above, comprises the following steps:

[0022] S1: During the waiting period after galvanizing, lower the wire box to pull the rope down, so that the dense mesh plate and the sparse mesh plate enter the interior of the galvanizing bath;

[0023] S2: The scraper located below the dense mesh plate and the sparse mesh plate first scrapes the front and back sides of the galvanizing tank to remove the residue on the inner wall.

[0024] S3: When the base frame touches the bottom, the drive rotary motor uses the transmission screw to drive the side plate to retract. At this time, the residue enters the cavity formed between the loose mesh plate and the dense mesh plate through the loose mesh plate, forming a limit and storage.

[0025] S4: When adjacent scraping edges are joined, the pull rope is used to pull them upward. At this time, the residue that is limited to the inside of the adjacent sparse mesh plate enters the inside of the transverse dense mesh plate and sparse mesh plate, and the residue is fully dredged to prevent leakage. S5: In addition, when adjacent scraping edges are joined, the guide tube at the end of the side tube is joined to the convex tube, so that the limiting strip is engaged in the inside of the positioning groove to form a limiting and sealing effect.

[0026] S6: Finally, after the side plate is removed, the fan above the cross frame is driven to transmit the air force to the interior of the vertically adjacent dense and sparse mesh plates through the convex pipe, duct, side pipe and transfer pipe, so that the stored residue is discharged outward, which is convenient for the next slag removal operation.

[0027] The beneficial effects of this invention are:

[0028] This invention replaces the traditional filter screen mechanism by using a combination of dense and sparse mesh plates and vertical assembly. During slag removal operations, the residue can be confined between the two plates, preventing leakage and achieving a storage effect that facilitates centralized cleaning and use. Compared with existing slag removal methods, it has the effect of high efficiency and thorough slag removal.

[0029] In addition, during the operation, the residue on the inner wall of the galvanizing tank can be scraped off first by scraping the edge to clean the inner wall and ensure the effect of the slag removal operation, which is convenient for subsequent galvanizing operations.

[0030] The invention, by adding a side pipe, allows the air force generated by the blower to be directed between the dense mesh plate and the sparse mesh plate, thereby enabling the rapid discharge of internal residues during cleaning, reducing the difficulty of manual handling, and facilitating efficient slag removal and cleaning operations.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figure 1-6 This invention provides an embodiment of a slag removal device and method for galvanizing pools:

[0049] Reference Figure 1 , Figure 2 and Figure 3A slag removal device for a galvanizing tank includes: a galvanizing tank 1, a crossbeam 2 and a slide block 3. The slide block 3 moves back and forth through an external transmission mechanism. A wire release box 301 is located inside the left and right ends of the slide block 3 and is connected to the crossbeam 2 through a pull rope 3011 in front of it to drive it to perform slag removal operations.

[0050] The bottom front and rear sides of the cross frame 2 are provided with side plates 201. The dense mesh plate 2011 and the sparse mesh plate 2012 at the bottom front and rear are used to scoop out the residue inside the galvanizing pool 1 and limit the scooped residue to achieve the effect of storage and prevent leakage.

[0051] The bottom of the side plate 201 is provided with a scraper 2014 for installing the dense mesh plate 2011 and the sparse mesh plate 2012. At the bottom of the cross frame 2, there are two back-to-back base frames 2013 for installing the horizontal dense mesh plate 2011 and the sparse mesh plate 2012. These, together with the vertical dense mesh plate 2011 and the sparse mesh plate 2012, form a limiting space to fix the residue in a certain area to facilitate the salvage operation.

[0052] The base frame 2013 and the scraper 2014 are both provided with scraping edges 2016 on their adjacent end faces and are connected to each other to form a seal. The scraping edge 2016 located at the lower end of the scraper 2014 is used to scrape the inner wall of the galvanizing tank 1 so that the residue falls off and achieves the effect of fully removing the slag.

[0053] A side pipe 203 is provided above the cross frame 2. After the residue is removed from the dense mesh plate 2011 and the slack mesh plate 2012, the wind generated by the fan above the cross frame 2 is blown into the interior of the dense mesh plate 2011 and the slack mesh plate 2012 to achieve the effect of discharging the residue.

[0054] This embodiment provides a slag removal mechanism for effectively removing galvanized residue. It utilizes vertical and horizontal dense mesh plates 2011 and sparse mesh plates 2012 in combination to replace the traditional filter screen mechanism. This mechanism can store and limit the residue during the slag removal process, effectively preventing leakage. In addition, it automatically scrapes off the residue from the inner wall of the galvanizing tank 1 during the slag removal process, ensuring sufficient slag removal and facilitating subsequent slag removal operations. Finally, the addition of side pipes 203 allows the residue to be discharged immediately after slag removal, facilitating the next slag removal operation.

[0055] Reference Figure 2 The vertical dense mesh plate 2011 and sparse mesh plate 2012 are provided with plate mechanisms on the left and right sides to connect the two. They are also used to scrape slag from the left and right inner walls of the galvanizing pool 1 to facilitate retrieval and prevent the formation of dirt that may affect subsequent galvanizing and cleaning operations.

[0056] Reference Figure 3 and Figure 4The base frame 2013 and the scraper 2014 are both provided with connecting rods 2015 that are connected and fixed to the cross frame 2, which are used to support the dense mesh plate 2011 and the sparse mesh plate 2012.

[0057] Reference Figure 3 The front and rear sides of the cross frame 2 are equipped with side frames 202. The guide rods 2021 inside the left and right sides form a sliding connection and support effect to the side plate 201, thus limiting its front and rear path.

[0058] Reference Figure 3 The middle interior of the side frame 202 is provided with a transmission screw 2022 that is rotatably connected to the boss 204 below the cross frame 2. The outer side of the transmission screw 2022 is spirally connected to the side plate 201 to drive it to move back and forth.

[0059] Reference Figure 3 A transmission gear shaft 2041 is rotatably installed between adjacent bosses 204, and is connected to the transmission screw 2022. A rotary motor 2042 is provided on the outside of the rear side of the cross frame 2. The rotary motor 2042 drives the transmission gear shaft 2041 and the transmission screw 2022 to rotate through the gear mechanism at its front end. The gear mechanism is rotatably installed between adjacent bosses 204.

[0060] Reference Figure 5 and Figure 6 The outer side of the boss 204 is provided with a protruding pipe 2031 that connects to the conduit 2032 on the side of the side pipe 203. The lower end of the side pipe 203 is provided with a transfer pipe 2035, which is used to connect the side pipe 203 and the cross frame 2, so that the wind can reach the interior of the dense mesh plate 2011 and the sparse mesh plate 2012.

[0061] Reference Figure 6 The outer side of the convex tube 2031 is a convex thick structure, and the end of the conduit 2032 is provided with a limiting strip 2033 that engages with the mounting seat inside the positioning groove 2034 on the outer side of the convex tube 2031 to form a seal and limit.

[0062] Reference Figure 1-6 A method for removing slag from a galvanizing tank, applied to the aforementioned slag removal device for a galvanizing tank, comprises the following specific steps:

[0063] S1: During the waiting period after galvanizing, the pull rope 3011 is lowered through the wire release box 301, so that the dense mesh plate 2011 and the loose mesh plate 2012 enter the interior of the galvanizing bath 1.

[0064] S2: The scraper 2014 located below the dense mesh plate 2011 and the sparse mesh plate 2012 first scrapes the front and rear sides of the galvanizing tank 1 to remove the residue on the inner wall.

[0065] S3: When the base frame 2013 touches the bottom, the drive rotary motor 2042 uses the transmission screw 2022 to drive the side plate 201 to retract. At this time, the residue enters the cavity formed between the loose mesh plate 2012 and the dense mesh plate 2011 through the loose mesh plate 2012, forming a limit and storage.

[0066] S4: When adjacent scraping edges 2016 are connected, the pull rope 3011 is used to pull them up. At this time, the residue that is limited to the inside of the adjacent netting plate 2012 enters the inside of the horizontal dense netting plate 2011 and netting plate 2012 to fully remove the residue and prevent leakage.

[0067] S5: In addition, when adjacent scraping edges 2016 are joined, the conduit 2032 located at the end of the side tube 203 is joined to the convex tube 2031, so that the limiting strip 2033 is engaged in the interior of the positioning groove 2034 to form a limiting and sealing effect.

[0068] S6: Finally, after the side plate 201 is removed, the fan above the cross frame 2 is driven to transmit the air force to the interior of the vertically adjacent dense mesh plate 2011 and sparse mesh plate 2012 through the convex pipe 2031, duct 2032, side pipe 203 and transfer pipe 2035, so that the stored residue is discharged outward, which is convenient for the next slag removal operation.

[0069] Understandably, this invention can replace the traditional filter screen mechanism, forming a storage limit for residue during the retrieval process, effectively preventing leakage, thereby improving the efficiency of slag removal operations, reducing the difficulty of workers' work, and protecting their own safety. In addition, it automatically scrapes off the residue on the inner wall of the galvanizing tank 1 during the retrieval process, ensuring sufficient retrieval for subsequent retrieval operations. Finally, the addition of the side pipe 203 allows the residue to be discharged immediately after retrieval, facilitating the next retrieval operation.
