Description

Technical Field

[0001] The utility model relates to the field of cast steel cooling wall structures, in particular to a cast steel cooling wall structure. Background Art

[0002] Cast steel is a kind of steel made by casting process. When casting steel, a cast steel cooling wall structure is needed. Cast steel cooling wall is a structure used for cooling equipment in high temperature environment, which has good high temperature resistance and corrosion resistance. The cooling pipes in the existing cooling wall are fixed inside the cast steel furnace, which is not easy to disassemble. When the cooling pipe is damaged, it is impossible to replace the pipe and repair it, which affects the use effect of the cast steel furnace. At the same time, the cooling device lacks airtightness. After a long time of use, the interface is prone to coolant leakage, which reduces the cooling effect of the cast steel furnace, pollutes the surrounding environment and affects the health of the staff.

[0003] A Chinese patent with announcement number CN220999694U discloses a cast steel cooling wall structure, including a cast steel furnace main body, wherein placement grooves are provided at the four ends of the cast steel furnace main body, and the upper and lower ends of the placement grooves are fixedly connected with conveying cross pipes and penetrate the four corners of the upper and lower ends of the cast steel furnace main body, and the opposite sides of the outer wall of the conveying cross pipe are fixedly connected with connecting pipes, and the opposite sides of the inner wall of the connecting pipe are threadedly connected with vertical pipes, and the upper and lower ends of the vertical pipe are respectively provided with upper threaded interfaces and lower threaded interfaces, and the upper and lower sides of the outer wall of the vertical pipe are provided with fastening rings, and the outer walls of the fastening rings are provided with multiple fixing blocks.

[0004] Although the cast steel cooling wall structure described in the above patent can open the door panel after the vertical pipe in the cast steel furnace body is damaged, and the upper threaded interface and the lower threaded interface on the vertical pipe can be unscrewed from the corresponding conveying cross pipe by twisting and rotating, so as to realize convenient replacement and maintenance of the damaged vertical pipe, but under the above replacement method, when the lower threaded interface on the vertical pipe is unscrewed from the lower conveying cross pipe, in order to avoid obstruction by the upper conveying cross pipe, it is necessary to tilt the vertical pipe relative to the joint pipe of the lower conveying cross pipe when screwing the vertical pipe, and at the same time, it is also necessary to tilt the vertical pipe when screwing the replaced vertical pipe onto the upper conveying cross pipe. Rotating the vertical pipe in a skewed manner will cause wear on the upper threaded interface and the lower threaded interface on the vertical pipe, thereby causing leakage at the interfaces at both ends of the vertical pipe after replacement, resulting in poor sealing performance of the vertical pipe after replacement, and making the maintenance efficiency of the vertical pipe relatively low.

[0007] By adopting the above technical solutions, when disassembling the damaged cooling vertical pipe, first, the screw sleeve on the upper side of the cooling vertical pipe is used to move the screw sleeve downward along the cooling vertical pipe to ensure the convenient separation of the upper end of the cooling vertical pipe from the upper cooling cross pipe. Then, the screw sleeve on the lower side of the cooling vertical pipe is rotated to separate the lower side of the cooling vertical pipe from the lower cooling cross pipe, so as to realize the convenient disassembly of the damaged cooling vertical pipe. When installing the replaced cooling vertical pipe, first, the screw sleeve is retracted onto the cooling vertical pipe, and the cooling vertical pipe is placed between the corresponding two connecting pipes. Then, by simply rotating the screw sleeves on the upper and lower sides of the cooling vertical pipe respectively, the quick installation of the replaced cooling vertical pipe can be achieved, and the sealing performance of the cooling vertical pipe after replacement and installation is ensured, and the maintenance efficiency of the cooling vertical pipe after replacement is ensured.

[0008] Furthermore, the outer wall of the connecting pipe has an external thread at the part that cooperates with the screw sleeve, and the size of the screw groove in the screw sleeve matches the outer diameter size of the connecting pipe with the external thread.

[0013] By adopting the above technical solutions, such a design can effectively ensure the sealing performance between the end part of the cooling vertical pipe and the screw sleeve.

[0014] Furthermore, a cover plate is installed on each of the installation grooves on the main body of the steel casting furnace through a hinge, and a limit position assembly is installed on the outer wall of the cover plate.

[0015] By adopting the above technical solution, the limiting assembly is mainly used to achieve reliable closing and limiting of the cover plate at the installation groove.

[0016] Furthermore, the limiting assembly includes a rotating rod installed in the middle of the outer wall of the cover plate, a sleeve installed in the middle of the rotating rod, screw heads formed at both ends of the rotating rod, an insert plate installed at each screw head, and a guide groove opened on the cover plate and located at the insert plate.

[0017] By adopting the above technical solution, the rotating rod can be rotated by moving the sleeve, and the rotating rod will rotate the screw head, and the screw head will rotate to make the plug plate slide along the guide groove under the action of the thread transmission.

[0018] Furthermore, the rotating rod is rotatably connected to the outer wall of the cover plate, the outer wall of the cover plate is provided with a concave structure at the position of the pull sleeve, and the screw head is threadedly connected to the plug plate.

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Such as Figure 1 , Figure 3 and Figure 4As shown in the figure, a cast steel cooling stave structure in this embodiment includes a main cast steel furnace body 1. A mounting groove 10 is respectively opened on the side walls around the main cast steel furnace body 1. Two square cooling horizontal pipes 4 are commonly installed on the upper and lower sides in the four mounting grooves 10. A cooling vertical pipe 5 is connected between the upper and lower cooling horizontal pipes 4 through a connecting pipe 8. A quick-connect sealing assembly 9 is respectively installed at the connection points of both ends of the cooling vertical pipe 5 and the corresponding connecting pipe 8. The quick-connect sealing assembly 9 includes a screw sleeve 902 slidably installed at both ends of the cooling vertical pipe 5, four lifting platforms 901 annularly installed on the outer wall of the screw sleeve 902, a first sealing ring 904 installed at the inner bottom end of the screw sleeve 902, and a second sealing ring 903 arranged above the first sealing ring 904 in the screw sleeve 902;

[0033] The embodiment of the present utility model provides a cooling vertical pipe 5 equipped with a sliding quick-connect sealing assembly 9 to achieve quick docking and installation with the cooling horizontal pipe 4, and a cast steel cooling stave structure with high maintenance efficiency, solving the problem in the prior art that when the lower threaded interface on the vertical pipe is unscrewed from the lower conveying horizontal pipe during the use of the cast steel cooling stave structure, in order to avoid the obstruction of the upper conveying horizontal pipe, it is necessary to skew the vertical pipe relative to the joint pipe of the lower conveying horizontal pipe when screwing the vertical pipe, and at the same time, it is also necessary to skew the vertical pipe when screwing the replaced vertical pipe onto the upper conveying horizontal pipe. Rotating the vertical pipe in a skewed manner will cause wear at the upper and lower threaded interfaces of the vertical pipe, resulting in leakage at the interfaces at both ends of the replaced vertical pipe, resulting in poor sealing performance of the vertical pipe after replacement, and low maintenance efficiency of the vertical pipe. The general idea of the embodiment of the present utility model to solve the above problems is: a sliding quick-connect sealing assembly 9 is respectively installed at both ends of the cooling vertical pipe 5, so that during the disassembly and assembly of the cooling vertical pipe 5, the screw sleeve 902 in the quick-connect sealing assembly 9 can be rotated to achieve the separation of both ends of the cooling vertical pipe 5 and the corresponding connecting pipe 8, avoiding the skewed screwing operation of the cooling vertical pipe 5 during replacement, ensuring the sealing performance of the cooling vertical pipe 5 after replacement and repair, and ensuring the replacement and repair efficiency of the damaged cooling vertical pipe 5.

[0034] As Figures 3 - 5 shown in the figure, in this embodiment, the outer wall of the connecting pipe 8 has an external thread at the part that cooperates with the screw sleeve 902, and the size of the screw groove in the screw sleeve 902 matches the outer diameter size of the connecting pipe 8 with the external thread.

[0035] As an implementation method, by screwing the screw sleeve 902 onto the outside of the connecting pipe 8 during the installation of the cooling vertical pipe 5, it can ensure the quick installation of the cooling vertical pipe 5 between the cooling horizontal pipes 4.

[0036] As Figures 3 - 4As shown, in this embodiment, the end of the cooling vertical pipe 5 has a convex edge, the lower side of the convex edge of the cooling vertical pipe 5 contacts the sealing ring 1 904, and the upper side of the cooling vertical pipe 5 contacts the sealing ring 2 903.

[0037] As an implementation method, since reliable sealing between the cooling riser 5 and the connecting pipe 8 cannot be achieved by simply relying on the threaded engagement between the screw sleeve 902 and the connecting pipe 8, a sealing ring 904 is installed in the screw sleeve 902, which can increase the sealing performance between the cooling riser 5 and the connecting pipe 8 under the action of the sealing ring.

[0038] like Figures 3 - 4 As shown, in this embodiment, the contact portion between the sealing ring 904 and the convex edge on the cooling vertical pipe 5 adopts a labyrinth structure.

[0039] As an implementation method, the sealing structure between the flanges at both ends of the cooling vertical pipe 5 and the sealing ring 2 903 increases the sealing area between the cooling vertical pipe 5 and the screw sleeve 902, ensuring reliable sealing between the screw sleeve 902 and the cooling vertical pipe 5 after screwing.

[0040] like Figures 1 - 2 As shown, in this embodiment, a cover plate 2 is installed at each installation groove 10 on the main body 1 of the steel casting furnace through a hinge, and a limit assembly 3 is installed on the outer wall of the cover plate 2.

[0041] As an implementation mode, the limiting assembly 3 is mainly used to realize reliable closing and limiting of the cover plate 2 at the installation groove 10 , so as to shield and protect the cooling vertical pipe 5 and the cooling horizontal pipe 4 with the help of the cover plate 2 .

[0042] like Figures 1 - 2 As shown, in this embodiment, the limit assembly 3 includes a rotating rod 304 installed in the middle of the outer wall of the cover plate 2, a sleeve 305 installed in the middle of the rotating rod 304, screw heads 302 formed at both ends of the rotating rod 304, an insert plate 301 installed at each screw head 302, and a guide groove 303 opened on the cover plate 2 at the insert plate 301.

[0043] As an implementation mode, when replacing a damaged cooling riser 5, it is necessary to first open the corresponding cover plate 2. When opening the cover plate 2, the sleeve 305 is first turned to rotate the rotating rod 304. After the rotating rod 304 rotates, the screw head 302 rotates. After the screw head 302 rotates, the plug plate 301 slides along the guide groove 303 under the action of the threaded transmission, so that after the limit at the plug plate 301 is released, the cover plate 2 can be conveniently opened.

[0044] like Figures 1 - 2 As shown, in this embodiment, the rotating rod 304 is rotatably connected to the outer wall of the cover plate 2, the outer wall of the cover plate 2 is located at the pull sleeve 305 and is a concave structure, and the screw head 302 is threadedly connected to the plug plate 301.

[0045] As an implementation mode, it can ensure that the shifting sleeve 305 can be easily shifted when the rotating rod 304 rotates, and avoid the cover plate 2 causing obstacles to the shifting of the shifting sleeve 305.

[0046] like Figures 1 - 2 As shown, in this embodiment, slots 6 are further provided on the two side walls of the installation slot 10 facing the plug board 301 , and the size of the slots 6 matches the size of the plug board 301 .

[0047] As an implementation mode, after the plug board 301 is inserted into the slot 6 , the cover plate 2 can be reliably limited and fixed at the installation groove 10 .

[0048] The specific implementation process of this embodiment is as follows: when in use, first install the cooling cross pipe 4 and the cooling vertical pipe 5 in the respective installation grooves 10 in the steel casting furnace body 1, and cover the cover plate 2, and then the steel casting furnace body 1 can be put into use. During use, the cooling liquid flowing in the cooling cross pipe 4 and the cooling vertical pipe 5 can realize the cooling function of the side wall of the steel casting furnace body 1. When the cooling vertical pipe 5 in the steel casting furnace body 1 is damaged and needs to be replaced, it is necessary to first open the corresponding cover plate 2 from the installation groove 10, and at the same time, through the screw sleeve 902 on the upper side of the cooling vertical pipe 5, move the screw sleeve 902 down along the cooling vertical pipe 5 to ensure the convenient separation of the upper end of the cooling vertical pipe 5 and the upper side of the cooling cross pipe 4, and then rotate the screw sleeve 902 on the lower side of the cooling vertical pipe 5. To separate the lower side of the cooling vertical pipe 5 from the cooling cross pipe 4 on the lower side, thereby realizing convenient disassembly of the cooling vertical pipe 5 after damage. When installing the replaced cooling vertical pipe 5, the screw sleeve 902 is first retracted onto the cooling vertical pipe 5, and the cooling vertical pipe 5 is placed between the corresponding two connecting pipes 8, and then the screw sleeves 902 on the upper and lower sides of the cooling vertical pipe 5 are only needed to be rotated respectively to realize the quick installation of the replaced cooling vertical pipe 5. During the replacement process of the cooling vertical pipe 5, the screw sleeve 902 slides along the length direction of the cooling vertical pipe 5, thereby effectively avoiding the skewed screwing operation of the cooling vertical pipe 5 when replacing and repairing it after damage, and preventing the cooling vertical pipe 5 from being poorly sealed at the end when replacing it after damage, so that the replacement efficiency of the cooling vertical pipe 5 after damage is higher.
