Description

Technical Field

[0001] This utility model belongs to the field of metallurgical technology, and in particular relates to a welding slag bag with a secondary hook. Background Technology

[0002] In the metallurgical industry, a large amount of high-temperature molten slag is typically generated. This slag directly affects the production efficiency, safety, environmental protection, and economic benefits of enterprises. Currently, enterprises commonly use foundry slag bags to load and handle this high-temperature molten slag. However, foundry slag bags have revealed numerous drawbacks during use, such as unstable quality, high maintenance rates, susceptibility to cracking, difficulty in repair, and short service life. These problems not only increase the operating costs of enterprises but also pollute the environment and are inconsistent with national industrial policies on energy conservation, emission reduction, and sustainable development. After loading molten slag, the slag bag heats up rapidly; measurements show that the temperature of the slag bag rises to approximately 600°C after loading. The slag is then rapidly cooled by spraying water. In the prior art, multiple horizontal ring plates are installed on the outer wall of the slag bag. Each horizontal ring plate has multiple vertical water distribution holes that penetrate the plate body. The cooling water of the slag bag is drawn down from the top of the slag bag and flows along the outer wall of the slag bag through the water distribution holes on the horizontal ring plate. Since the water distribution holes are opened on the horizontal ring plate, the integrity of the horizontal ring plate is affected, thereby affecting the reinforcement stability of the slag bag by the horizontal ring plate. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a welding slag bag with a secondary hook to solve the technical problem that opening water distribution holes on the horizontal ring plate affects the structural strength of the horizontal ring plate in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model for a welding slag bag with a secondary hook is as follows:

[0005] Welding slag bags with auxiliary hooks include:

Detailed Implementation

[0041] The welding slag bag with auxiliary hook of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments:

[0042] as follows Figures 1-7As shown, the welding slag bag with auxiliary hook of this utility model includes a bag body 1 and a spherical crown head 2 disposed at the bottom of the bag body 1. The spherical crown head 2 is welded to the bag body 1, and the bag body 1 is frustum-shaped. Two trunnions 3 are provided on both sides of the bag body, and the two trunnions 3 are coaxially fixed on the bag body 1, that is, the two trunnions 3 are arranged at 180°. An upper ring plate 7 and a middle ring plate 8 are provided on the outer surface of the bag body 1. The middle ring plate 8 is disposed below the upper ring plate 7 at intervals. A lower ring plate 9 is fixed on the outer side of the spherical crown head 2, and the lower ring plate 9 is disposed below the middle ring plate 8 at intervals. In this embodiment, the lower ring plate 9 is located 100mm below the upper end face of the spherical crown head 2. Multiple longitudinal stiffeners 10 are provided between adjacent ring plates. The stiffeners 10 are welded to the ring plates and form a mesh structure on the outer side of the bag body 1. By setting the ring plate and stiffening plate 10, not only is the connection strength between the slag body 1 and the spherical cap 2 increased, but the structural strength of the entire welding slag ...

[0043] In this embodiment, the upper ring plate 7, the middle ring plate 8, and the lower ring plate 9 are all Z-direction performance plates. The upper ring plate 7 is fixedly connected to the top of the package 1 by an edge reinforcing rib plate.

[0044] In this embodiment, two trunnion-side furnace legs 6 are provided on the welding slag bale at positions corresponding to the trunnion 3. These trunnion-side furnace legs 6 are fixedly connected to the middle ring plate 8, the bale body 1, the spherical cap 2, and the lower ring plate 9, respectively. Furthermore, the trunnion-side furnace legs 6 are located at the lower end of the trunnion block 4, and their height is greater than the distance between the middle ring plate 8 and the bottom of the spherical cap 2. The trunnion-side furnace legs 6 enhance the structural strength of the bale body 1 and the spherical cap 2, thereby improving the service life of the welding slag bale.

[0045] A knocking platform 11 is provided on both sides of the bag body 1. In this embodiment, there are two knocking platforms 11. The two knocking platforms 11 and the two trunnions 3 are evenly distributed in the circumference of the bag body 1. That is, the straight line of the two knocking platforms 11 is perpendicular to the straight line of the two trunnions 3.

[0046] Two tapping platform side furnace legs 14 are provided on the welding slag bale, and the two tapping platform side furnace legs 14 are respectively provided corresponding to the tapping platform 11. A secondary hook 15 is hinged to the tapping platform side furnace leg 14. Specifically, the tapping platform side furnace leg 14 includes two spaced support plates. In this embodiment, the two support plates are 200mm apart, and hinge holes are provided on the support plates. The secondary hook 15 is hinged relative to the support plates through a hinge shaft passing through the hinge hole. A limiting post 21 is provided between the two support plates. The limiting post 21 is fixed to the outer circumference of the bale body 1, and the limiting post 21 limits the secondary hook 15 so that the secondary hook 15 remains horizontal in its natural state. In this embodiment, the limiting post 21 is arranged horizontally. A wear-resistant plate 18 is fixedly pasted on the side of the secondary hook 15 that contacts the gantry crane wire rope. In this embodiment, the wear-resistant plate 18 is 14mm thick.

[0047] The auxiliary hook 15 has a through hole, and the support plate of the furnace leg 14 on the side of the ladle platform has a first positioning hole 19 and a second positioning hole 20. When the through hole of the auxiliary hook 15 is connected to the first positioning hole 19 by a positioning pin, the auxiliary hook 15 is kept in a horizontal state, which makes it convenient for the gantry crane to hook the auxiliary hook 15. When the through hole of the auxiliary hook 15 is connected to the second positioning hole 20 by a positioning pin, the hook body of the auxiliary hook 15 is facing upward and abutting against the outer side of the ladle body 1, which can avoid the setting of the auxiliary hook 15 from interfering with the transfer process of the welding slag ladle.

[0048] Water collecting plates 16 are respectively provided on the outer edges of the upper ring plate 7 and the middle ring plate 8. Several overflow holes 17 are spaced apart on the lower side of the water collecting plates 16. A drainage plate 13 corresponding to the overflow holes 17 is provided below the overflow holes 17 on the outer wall of the package body 1. In this embodiment, the side of the drainage plate 13 facing the package body is arc-shaped to fit the outer side of the package body 1, facilitating the fixation of the drainage plate 13 relative to the package body 1. In this embodiment, the thickness of the water collecting plate 16 is 3mm. The drainage plate 13 includes a side plate and an inclined vertical plate. The top of the side plate is fixedly connected to the upper ring plate 7, and the end of the side plate away from the package body 1 is fixedly connected to the inclined vertical plate. The side of the side plate facing the package body 1 is arc-shaped to facilitate the fixation of the drainage plate 13 relative to the package body.

[0049] In this embodiment, the upper surface of the package 1 is an inclined plane, which is perpendicular to the outer peripheral surface of the package 1. That is, the inclination of the inclined plane is 90° to the outer side of the package 1. The inclined plane can disperse and overflow the sprayed cooling water, and the outer inclined wall of the package 1 can also guide the flow of cooling water.

[0050] The diameter of the water collecting plate 16 is larger than the diameter of the upper end face of the baffle 1. This allows cooling water overflowing from the upper end face of the baffle 1 to collect in the water collecting trough formed by the annular plate and the water collecting plate 16. This prevents cooling water overflowing from the baffle 1 from flowing out from the outer edge of the upper annular plate 7, thus preventing it from falling directly to the ground. Instead, the cooling water on the upper annular plate 7 flows from the overflow hole 17 on the water collecting plate 16 and the guide plate 13 to the outer wall of the baffle 1, thereby improving the cooling effect of the welding slag baffle and significantly reducing scale buildup on the outer wall of the baffle 1. Furthermore, in this embodiment, placing the overflow hole 17 on the water collecting plate 16, rather than on the annular plate, ensures the integrity of the annular plate and makes the connection between the annular plate and the baffle 1 more stable.

[0051] To increase the connection strength between the trunnion 3 and the package body 1, in this embodiment, the package body 1 is fixed with a cross-shaped rib plate at the corresponding position of the trunnion 3, and a trunnion block 4 is fixed on the cross-shaped rib plate. The trunnion and the trunnion block are connected by an interference fit, and the trunnion block 4 and the package body 1 are fixedly connected by a trunnion block support plate 5. The trunnion block support plate 5 is distributed on both sides of the trunnion block.

[0052] In order to ensure the structural strength of the punching platform 11, in this embodiment, the punching platform 11 is located below the upper ring plate 7, and a punching platform stiffener 12 is fixed between the punching platform 11 and the upper ring plate 7. The two ends of the punching platform 11 are respectively fixedly connected to the longitudinal stiffener 10.

[0053] When the welding slag bale of this utility model is turned over, it can be transported by trolley or trailer, or by lifting the auxiliary hook 15 upward with a gantry crane. The slag bale rotates around the trunnion 3 to complete the tilting action. That is, this utility model can be transported by trolley or trailer, and can also be lifted and tilted by gantry crane without the need to lift the bale cart, thus improving the working efficiency of the slag bale. Moreover, the lower ring plate 9 is set below the spherical crown head, and the lower ring plate 9 and the middle ring plate 8 are connected by longitudinal stiffeners 10, thereby further strengthening the structural strength of the bale body 1 and the spherical crown head 2, and thus improving the service life of the welding slag bale.

[0054] The overall structure of the welding slag bag of this utility model is symmetrical, which will not cause stress concentration. The main material is low alloy high strength steel plate, and the steel plate is manufactured by hot rolling, which can refine the grains and improve the mechanical properties of the steel plate, thereby improving the service life of the slag bag.

[0055] In the above embodiments, the furnace leg on the side of the ladle-knocking platform includes two spaced-apart support plates. The support plates have hinge holes. The auxiliary hook is hinged to the support plates via a hinge shaft passing through the hinge holes. A limiting post is provided between the two support plates. The limiting post is fixed to the outer circumference of the ladle body and limits the auxiliary hook so that the auxiliary hook remains horizontal in its natural state. In other embodiments, the limiting post may not be provided, or other structures may be used to limit the position of the auxiliary hook.

[0056] In the above embodiments, the auxiliary hook has a through hole, and the support plate of the furnace leg on the side of the tapping platform has a first positioning hole and a second positioning hole. When the through hole of the auxiliary hook is connected to the first positioning hole by a positioning pin, the auxiliary hook remains in a horizontal state; when the through hole of the auxiliary hook is connected to the second positioning hole by a positioning pin, the auxiliary hook body faces upward and abuts against the outer side of the bale. In other embodiments, the first positioning hole and the second positioning hole may not be provided.

[0057] In the above embodiments, a plurality of overflow holes are spaced apart on the lower side of the water collection plate, and a flow guide plate corresponding to the overflow holes is provided below the overflow holes on the outer wall of the package; in other embodiments, the overflow holes can also be opened on the ring plate, in which case the overflow holes are arranged to penetrate the ring plate from top to bottom.

[0058] In the above embodiments, the upper surface of the package is an inclined plane, which is perpendicular to the outer peripheral surface of the package; in other embodiments, the upper surface of the package can also be a horizontal plane.
