Description

Technical Field

[0001] This application relates to billet descaling technology, and more particularly to a high-pressure water descaling device. Background Technology

[0002] During the production of coiled wire rod, when the steel billet is heated in the furnace, the furnace contains a large amount of oxidizing gases, causing oxidation and the formation of an iron oxide scale on the billet surface. If this iron oxide scale is pressed into the steel surface during the rolling process, it will cause pitting on the surface of the coiled wire rod, affecting its quality. To improve the quality of the coiled wire rod, after the billet exits the furnace, it needs to be descaled by a high-pressure water descaling machine to remove the iron oxide flakes from the billet surface before rolling.

[0003] Currently, an existing high-pressure water descaling machine includes a housing with openings at both ends. Inside the housing is a conveyor roller for transporting steel billets, and inside the housing is a spray structure that can spray high-pressure water onto the four surfaces of the steel billets. At both openings are blocking structures for preventing iron oxide flakes from splashing. The blocking structures are composed of multiple strip-shaped iron chains.

[0004] However, existing chains used to prevent iron oxide flakes from splashing are composed of multiple interlocking iron rings (such as...). Figure 1 As shown in the diagram, the entire chain has many gaps, meaning there are many gaps connecting the inside of the box to the outside. When the chain blocks the splashing iron oxide scale, iron oxide scale smaller than the gaps in the chain can easily pass through the gaps and splash outside the box. This can not only easily burn passing workers, but also the high temperature of the iron oxide scale can easily burn the surrounding electrical wiring. Utility Model Content

[0005] This application provides a high-pressure water descaling device to solve the problem that existing high-pressure water descaling machines have poor effect in preventing iron oxide scale from splashing when removing iron oxide scale from the surface of steel billets.

[0006] This application provides a high-pressure water descaling device, including a housing, the interior of which is provided with a conveyor roller and a water spray structure, and openings are provided on both sides of the housing; The opening is provided with a blocking structure to block iron oxide scale; The blocking structure is composed of multiple vertically distributed blocking components, and when the blocking structure is in a free state, two adjacent blocking components are in contact. The blocking component includes multiple blocking blocks I arranged vertically, with a blocking block II between two adjacent blocking blocks I. The two ends of the blocking block II are respectively in contact with and rotatably connected to their corresponding blocking blocks I.

[0007] Optionally, the blocking block I and the blocking block II are rectangular plate structures. Both ends of the blocking block I are provided with sockets, and both ends of the blocking block II are provided with protrusions that are adapted to the sockets. The protrusions and their corresponding sockets are inserted into each other. The protrusion position contacts and rotates with the socket position, and the contact ends of the protrusion position and the socket position are both rounded.

[0008] Optionally, the blocking structure further includes a mounting plate, wherein the upper end of the blocking member is detachably connected to the lower end of the mounting plate; The upper end of the opening has an installation port; The blocking member passes through the mounting opening, and the mounting plate is fixed to the upper end of the mounting opening and closes the mounting opening.

[0009] Optionally, a connecting plate perpendicular to the lower end of the mounting plate is fixed, and the middle position of the uppermost blocking block I is fixedly connected to the connecting plate by bolt I.

[0010] Optionally, the upper end of the mounting plate is fixed with two lifting lugs for connecting with the lifting device.

[0011] Optionally, the protrusion of the blocking block II is provided with a pin that passes through the protrusion and is detachably fixed to the protrusion; The blocking block I has a socket concentric with the pin, and the pin extends into the corresponding socket and rotates in contact with the socket.

[0012] Optionally, the number of the blocking structures is two, and the blocking elements of the two blocking structures are staggered.

[0013] The high-pressure water descaling device provided in this application has a blocking structure at both openings of the housing to block iron oxide scale. The blocking structure consists of multiple vertically distributed blocking components. When the blocking structure is in a free state, adjacent blocking components are in contact. The blocking components include multiple vertically distributed blocking blocks I, with blocking blocks II between adjacent blocking blocks I. The two ends of the blocking block II are in contact with and rotatably connected to their corresponding blocking blocks I. This allows the blocking components to have a certain degree of freedom after the blocking blocks I and II are rotatably connected during use, ensuring that the steel billet can pass through the opening smoothly. Compared with the existing iron chain blocking method, the contact between blocking blocks I and II, and the contact between adjacent blocking components, can reduce the gaps between the inside of the housing and the outside, thereby effectively reducing the amount of iron oxide scale splashing and reducing the risk of burns to workers and damage to surrounding electrical wiring.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0018] like Figures 1-6 As shown: An embodiment of this application provides a high-pressure water descaling device, which includes a housing 1. Inside the housing 1, there is a conveying roller 2 for conveying steel billets and a water spraying structure 3 that can spray high-pressure water onto the four surfaces of the steel billets. The conveying roller 2 is distributed along the length of the housing 1, and openings 101 are provided on both sides of the housing 1.

[0019] Specifically, the water spray structure 3 includes a rectangular ring structure water spray pipe 301, which is connected to a water inlet pipe 302. Each of the four ends of the water spray pipe 301 is provided with multiple equidistant high-pressure nozzles 303.

[0020] In this embodiment, the conveyor roller 2 is composed of multiple conveyor rollers distributed along the length of the box 1. The conveyor rollers are connected to a motor that can drive them to rotate via a coupling. The conveyor rollers and the water spray structure 3 are both existing technologies and will not be described in detail.

[0021] A blocking structure 4 for blocking iron oxide scale is provided at the opening 101 position.

[0022] The blocking structure 4 is composed of multiple blocking members 401 that are vertically distributed along the width direction of the box 1, and when the blocking structure 4 is in a free state, two adjacent blocking members 401 are in contact.

[0023] Furthermore, the blocking members 401 located on both sides of the blocking structure 4 contact the two ends of the opening 101 respectively, in order to improve the effect of blocking the splashing of iron oxide sheets.

[0024] The blocking component 401 includes multiple blocking blocks I 402 arranged vertically, and a blocking block II 403 is provided between two adjacent blocking blocks I 402. The two ends of the blocking block II 403 are in contact with and rotatably connected to their corresponding blocking blocks I 402. Specifically, the blocking blocks I 402 and blocking blocks II 403 rotate along the billet moving direction.

[0025] In this embodiment, the water inlet pipe 302 is connected to a high-pressure water source, which provides high-pressure water to the spray structure 3. The housing 1 is installed above the slag flushing ditch.

[0026] In use, the billet moves from left to right (i.e., towards position 1) via the roller conveyor mechanism. When the billet reaches the opening 101 on the left side of the box 1, it pushes the blocking member 401 located on the right side of the billet and on the left side of the box 1 to rotate. The lower part of these rotating blocking members 401 always adheres to the upper end of the billet when in contact with it, ensuring that the billet enters the box 1 smoothly. After the billet enters the box 1, the conveyor roller 2 moves the billet. When the billet passes the water spray structure 3, the water spray structure 3 sprays high-pressure water onto the four surfaces of the billet. The high-pressure water impacts the iron oxide flakes on the surface of the billet, removing them. The iron oxide flakes on the surface, the iron oxide flakes detached from the billet, and the wastewater after impacting the billet fall into the slag flushing ditch. After passing through the water spray structure 3, the billet moves to the right side of the box 1. When the billet reaches the opening 101 on the right side of the box 1, it pushes the blocking members 401 located on the right side of the billet to rotate. The lower sections of these rotating blocking members 401 always adhere to the upper end of the billet when in contact with it, ensuring that the billet can be smoothly removed from the box 1. When the blocking members 401 on the left or right side of the box 1 detach from the billet, these blocking members 401 will return to a vertically distributed state according to their own gravity. In the above process, since the blocking members 401 on both sides of the box 1 can rotate along the direction of billet movement, the blocking members 401 have a certain degree of freedom, which ensures that the billet can pass smoothly through the opening 101. Furthermore, due to the contact between blocking block I 402 and blocking block II 403, the contact between two adjacent blocking components 401, and the fact that blocking component 401 can always adhere to the upper end of the steel billet after contact with the steel billet, the gap between the inside of the box 1 and the outside can be reduced, thereby effectively reducing the amount of iron oxide scale splashed out of the box 1, improving the effect of blocking iron scale splashing, and reducing the risk of workers being burned or the surrounding electrical circuits being damaged.

[0027] In some embodiments of this application, blocking block I 402 and blocking block II 403 are rectangular plate structures. Both ends of blocking block I 402 are provided with insertion slots 4021 that pass through blocking block I 402. Both ends of blocking block II 403 are provided with protrusions 4031 that are adapted to the insertion slots 4021. The protrusions 4031 and their corresponding insertion slots 4021 are inserted into each other, that is, the protrusions 4031 are inserted into their corresponding insertion slots 4021. The positions of the protrusions 4031 and the insertion slots 4021 are in contact and rotatably connected. The contact ends of the protrusions 4031 and the insertion slots 4021 are all rounded to ensure that blocking block I 402 and blocking block II 403 can rotate smoothly. Moreover, after blocking block I 402 and blocking block II 403 rotate, blocking block I 402 and blocking block II 403 are always in a close fit, so that there are no gaps on the entire blocking component 401, and the effect of blocking iron oxide scale splashing is good.

[0028] In some embodiments of this application, the blocking structure 4 further includes a mounting plate 5. The upper end of the blocking member 401 is detachably connected to the lower end of the mounting plate 5. The upper end of the opening 101 has a mounting port 102. The blocking member 401 passes through the mounting port 102, and the mounting plate 5 is fixed to the upper end of the mounting port 102 and closes the mounting port 102. Specifically, the mounting plate 5 is fixedly connected to the upper end of the opening 101 by bolt II.

[0029] In use, simply remove bolt II and then lift the mounting plate 5 upwards to replace the blocking component 401, thus facilitating the replacement of the blocking component 401.

[0030] In some embodiments of this application, a connecting plate 6 perpendicular to the lower end of the mounting plate 5 is welded and fixed thereto. The middle position of the uppermost blocking block I 402 is fixedly connected to the connecting plate 6 by bolt I 7. Specifically, a through hole I 8 is opened in the middle position of the blocking block I 402, and the connecting plate 6 has threaded holes I 4022 that are the same number as the blocking members 401 and correspond one-to-one. After the bolt I 7 passes through the through hole I 8 and engages with the threaded hole I 4022, the bolt I 7 presses the uppermost blocking block I 402 tightly onto the connecting plate 6, that is, fixes the blocking members 401 onto the connecting plate 6.

[0031] When in use, the blocking component 401 can be removed from the mounting plate 5 simply by removing the bolts, which makes it easy to remove the blocking component 401 when replacing it.

[0032] In some embodiments of this application, the upper end of the mounting plate 5 is fixed with two lifting lugs 9 for connecting with a lifting device, so as to facilitate the lifting equipment to lift the mounting plate 5.

[0033] In some embodiments of this application, the protrusion 4031 of the blocking block II 403 is provided with a pin 404 that passes through the protrusion 4031 and is detachably fixed to the protrusion 4031. Specifically, the protrusion 4031Ⅱ has through holes Ⅱ4032 distributed along the width direction of the housing 1, the protrusion 4031 has a blind hole 4033 perpendicular to the through hole Ⅱ4032, the blind hole 4033 has a threaded hole Ⅱ4034 that communicates with and is perpendicular to the through hole Ⅱ4032, the pin 404 has a limiting hole 4041 that is concentric with the threaded hole Ⅱ4034, the threaded hole Ⅱ4034 is engaged with an internal hex bolt 405, and the head of the internal hex bolt 405 is located in the blind hole 4033. The internal hex bolt 405 extends into the limiting hole 4041. The insertion port 4021 of the blocking block Ⅰ402 has an insertion hole 4023 concentric with the pin 404. The insertion hole 4023 passes through the blocking block Ⅰ402, and the pin 404 extends into the corresponding insertion hole 4023 and rotatably connects with the insertion hole 4023.

[0034] Furthermore, in order to facilitate the alignment of the limiting hole 4041 with the threaded hole II 4034, the insertion hole 4023 is provided with a limiting block 4024 that is integral with the blocking block I 402. The pin 404 has a limiting groove 4042 that is adapted to the limiting block 4024. After the limiting groove 4042 and the limiting block 4024 are engaged, the limiting hole 4041 and the threaded hole II 4034 are concentric.

[0035] In use, first insert the protrusion of blocking block II 403 into the socket 4021 of blocking block I 402. Then, insert pin 404 into socket 4023 and through hole II 4032, and make limiting groove 4042 cooperate with limiting block 4024. Then, make internal hex bolt 405 engage with threaded hole II 4034, and extend internal hex bolt 405 into limiting hole 4041. At this time, pin 404 is fixed on protrusion 4031, and pin 404 is rotatably connected to the socket 4021 of blocking block I 402. This realizes the detachable rotatable connection between blocking block I 402 and blocking block II 403. This not only facilitates the connection between blocking block I 402 and blocking block II 403, but also, if blocking block I 402 or blocking block II 403 is damaged, only the damaged blocking block I 402 or blocking block II 403 needs to be replaced, without replacing the entire blocking component 401.

[0036] In some embodiments of this application, there are two blocking structures 4, and the blocking elements 401 of the two blocking structures 4 are staggered, which can improve the effect of blocking iron pieces from splashing.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
