[0001] The utility model relates to the technical field of ladle, in particular to a ladle water outlet with a bowl-shaped sealing ring. Background Art

[0002] When the ladle outlet is connected to the long nozzle, in order to ensure the airtightness of the connection, a sealing ring needs to be installed on the outer end of the ladle outlet. However, the sealing ring is directly installed on the outer wall of the steel shell. The heat generated during pouring at the ladle outlet will be directly transferred to the sealing ring through the steel shell. Under long-term work, the service life of the sealing ring is easy to reduce. If the sealing ring and the steel shell can maintain a certain distance, the service life of the sealing ring can be effectively improved.

[0003] In order to solve the above problems, we proposed a ladle outlet with a bowl-shaped sealing ring. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a ladle water outlet with a bowl-shaped sealing ring, comprising a water outlet body, the upper outer wall of the water outlet body is fixedly provided with a stepped platform, the middle part of the water outlet body is provided with a casting hole, the outer wall of the water outlet body is fixedly sleeved with a steel shell, the upper end of the steel shell is fixedly connected with a stepped shell wrapping the stepped platform, the middle part of the step shell is provided with a through hole 1, the outer wall movable sleeve of the steel shell is provided with a movable ring located at the lower side of the step shell, the lower side wall of the movable ring is fixedly connected with a plurality of vertical downward support plates, the support plates are distributed at equal intervals around the steel shell, a plurality of evenly distributed springs are provided between the upper end of the movable ring and the step shell, the outer wall fixed sleeve of the support plate is provided with a steel pipe close to the lower end of the support plate, the outer wall sleeve of the steel pipe is provided with a sealing ring, the middle part of the lower end of the sealing ring is provided with a through hole 2, and the inner bottom wall of the sealing ring is squeezed and fitted with the lower end of the steel pipe.

[0006] In the above-mentioned ladle outlet with a bowl-shaped sealing ring, a limit block located between the support plates is fixedly provided on the outer wall of the steel shell, and the thickness of the limit block is smaller than the thickness of the support plate.

[0007] In the above-mentioned ladle outlet with a bowl-shaped sealing ring, a gasket located outside the second opening is fixedly provided on the inner bottom wall of the sealing ring, and a distance is set between the outer wall of the gasket and the inner wall of the steel pipe, and the distance is slightly smaller than the thickness of the support plate.

[0008] In the above-mentioned ladle outlet with a bowl-shaped sealing ring, the outer wall of the steel pipe is inclined from top to bottom and from outside to inside.

[0009] In the above-mentioned ladle outlet with a bowl-shaped sealing ring, the size of the second opening is larger than that of the first opening, and the size of the first opening is larger than that of the pouring hole.

[0010] In the above-mentioned ladle outlet with a bowl-shaped sealing ring, the step platform includes two steps, the size of the upper step of the step platform is larger than the size of the lower step of the step platform, and the upper end of the spring is fixedly connected to the lower step of the step shell.

[0011] Compared with the existing technology, the advantages of the ladle outlet with a bowl-shaped sealing ring are:

[0012] The outer wall of the sealing ring of the utility model is squeezed and fitted with the long water outlet, and the gasket inside the sealing ring is squeezed and fitted with the lower side wall of the steel shell, so that the outlet body and the long water outlet are tightly connected. Since there are multiple support plates between the sealing ring and the steel shell, the rate of heat transfer from the steel shell to the sealing ring is slowed down. Moreover, when the ladle water outlet is removed from the relevant device after completing the work, the spring pushes the movable ring to move downward, so that the support plate drives the steel pipe to move to the lower end of the steel shell, which is beneficial to the heat dissipation of the sealing ring and the gasket, thereby increasing the service life of the sealing ring.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3A ladle drain with a bowl-shaped sealing ring comprises a drain body 1, a stepped platform 2 is fixedly arranged on the upper outer wall of the drain body 1, the stepped platform 2 comprises two steps, the upper step of the stepped platform 2 is larger than the lower step of the stepped platform 2, a pouring hole 3 is opened in the middle of the drain body 1, the pouring hole 3 is used for molten steel to pass, a steel shell 4 is fixedly sleeved on the outer side wall of the drain body 1, a stepped shell 5 wrapping the stepped platform 2 is fixedly connected to the upper end of the steel shell 4, and the stepped shell 5 A through opening 6 is provided in the middle part, and the outer wall of the steel shell 4 is movably sleeved with a movable ring 7 located at the lower side of the step shell 5. The lower side wall of the movable ring 7 is fixedly connected with a plurality of vertically downward supporting plates 8. The supporting plates 8 have a certain thickness. When the molten steel flows through the pouring hole 3, part of the heat will be transferred to the steel shell 4 through the downspout body 1. Under the cooling effect of the air around the supporting plates 8, the speed of heat transfer from the steel shell 4 to the outer wall of the supporting plates 8 is delayed, and the supporting plates 8 are distributed around the steel shell 4 at equal intervals.

[0019] A plurality of evenly distributed springs 9 are arranged between the upper end of the movable ring 7 and the stepped shell 5, and the upper end of the spring 9 is fixedly connected to the lower step of the stepped shell 5, and the upper step of the stepped shell 5 can provide a fulcrum for the clamping mechanism, so that the steel shell 4 together with the lower water outlet body 1 is fixedly connected with the corresponding upper water outlet of the ladle, and the outer wall of the support plate 8 is fixedly sleeved with a steel pipe 10 close to the lower end of the support plate 8, and the outer wall of the steel pipe 10 is sleeved with a sealing ring 11, and the outer wall of the steel pipe 10 is inclined, and is inclined from top to bottom and from outside to inside, so that the long water outlet and the sealing ring 11 are squeezed and fitted under the action of external force, and the sealing ring 11 is bowl-shaped, and a through-port 2 12 is opened in the middle part of the lower end of the sealing ring 11, and the size of the through-port 2 12 is larger than the size of the through-port 1 6, and the size of the through-port 1 6 is larger than the size of the pouring hole 3, so as to reduce the possibility of contact between the molten steel flowing out of the pouring hole 3 and the steel shell 4 and the sealing ring 11, and the inner bottom wall of the sealing ring 11 is squeezed and fitted with the lower end of the steel pipe 10.

[0020] The outer wall of the steel shell 4 is fixedly provided with a limit block 13 located between the support plates 8. The thickness of the limit block 13 is less than the thickness of the support plate 8. The limit block 13 can prevent the movable ring 7 from falling off the steel shell 4, and will not have friction contact with the inner wall of the steel pipe 10 during the movement of the steel pipe 10.

[0021] The inner bottom wall of the sealing ring 11 is fixedly provided with a gasket 14 located outside the second through-port 12. A spacing is provided between the outer wall of the gasket 14 and the inner wall of the steel pipe 10, and the spacing is slightly smaller than the thickness of the support plate 8. When the sealing ring 11 is sleeved on the steel pipe 10, the outer wall of the gasket 14 is squeezed and contacted with the inner wall of the support plate 8, thereby improving the connection strength of the sealing ring 11. When the ladle outlet and the long outlet are connected, the long outlet pushes the sealing ring 11 upward, and the movable ring 7 is pushed upward. At this time, the spring 9 is compressed, and the gasket 14 is squeezed and fitted with the lower side wall of the steel shell 4. After the ladle outlet and the long outlet are fixedly connected, the sealing ring 11 and the gasket 14 The corresponding joints are sealed to ensure the air tightness of the connection between the ladle water outlet and the long water outlet. At the same time, since the support plate 8 forms a barrier for the steel pipe 10 and the steel shell 4, the heat transfer from the steel shell 4 to the steel pipe 10 is delayed, thereby reducing the concentration of heat on the sealing ring 11. Moreover, when the ladle water outlet stops working and is removed, the spring 9 pushes the movable ring 7 downward to move the steel pipe 10 to the lower end of the steel shell 4, and the sealing ring 11 is relatively far away from the water outlet body 1. At this time, the sealing ring 11 can be cooled faster. In summary, it can be seen that the utility model can improve the service life of the sealing ring 11 to a certain extent.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
