Description

Technical Field

[0001] This utility model relates to the technical field of water beam devices, and in particular to a water beam sealing device for a walking beam furnace. Background Technology

[0002] The water beam sealing device of a walking beam furnace is an important component of the furnace, primarily used to support and transport steel billets, while also serving cooling and protection functions. Specifically, a cooling medium, usually saturated water, is introduced into the water beam. Utilizing the principle of water vaporization cooling, the water absorbs the heat absorbed by the water beam under high-temperature conditions, turning the water into a steam-water mixture, which is then returned to the steam drum. This process effectively reduces the temperature of the water beam, preventing damage due to overheating, and also ensuring that the steel billets do not suffer quality problems during heating due to overheating of the water beam.

[0003] After the walking beam furnace is used up, a certain amount of cooling medium is usually reserved in the water beam to protect it.

[0004] However, existing water beam media inlet and outlet sealing structures all use a single sealing structure, such as flange seal or sealing cap seal. However, with a single sealing structure, when the sealing structure is disconnected from the media inlet and outlet, the media inside the water beam will be directly discharged. This process makes it inconvenient for operators to connect the media input component and the subsequent recovery component to the media inlet and outlet. At the same time, the single sealing structure is prone to damage or leakage due to overheating of the water beam. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a water beam sealing device for a walking beam furnace to more accurately resolve these issues.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a water beam sealing device for a walking beam furnace, characterized in that it includes a frame, a plurality of fixed water beams disposed within the frame, and movable water beams disposed inside the frame and located between two of the fixed water beams. The movable water beams are arranged in a plurality of manner, and each movable water beam has a translation frame connected to its bottom end. Both the fixed and movable water beams are provided with a cooling medium inlet and a cooling medium outlet. Each cooling medium inlet and outlet is provided with a sealing element, the bottom end of which is threaded. The sealing element is connected to a sealing cap. The sealing element includes an outer cover connected to the cooling medium inlet and the cooling medium outlet, a conical platform disposed inside the outer cover and located below the outer cover, and an annular body disposed inside the outer cover and located above the outer cover. A retainer is disposed on the inner side of the annular body, and a flow gap is left between the retainer and the annular body. A sealing ball is disposed inside the outer cover and located between the retainer and the conical platform. A return spring is disposed between the retainer and the sealing ball, and the return spring is connected to the retainer.

[0008] Furthermore, the inner side of the annular body is provided with a sliding groove, and the two sides of the retainer are provided with sliders that cooperate with the sliding groove.

[0009] Furthermore, the fixed water beam of this utility model includes a first support frame, two first side columns disposed below the first support frame, and a first central column disposed between the two first side columns. The first central column is provided with a cooling medium injection port and a cooling medium output port. The first support frame, the first side columns, and the first central column are all provided with first cooling channels.

[0010] Furthermore, the movable water beam of this utility model includes a second support frame, two second side columns disposed below the second support frame, and a second central column disposed between the two second side columns.

The second support frame, the second side columns, and the second central column are all provided with second cooling channels.

[0011] Furthermore, in this invention, the conical platform, annular body, and retainer within the cooling medium inlet and outlet are arranged in opposite directions.

[0012] The beneficial effects of this utility model are:

[0013] The seal and the sealing cap work together to achieve a double-sealed structure for the cooling medium inlet and outlet. This double-sealed structure effectively prevents media leakage. The seal effectively seals the cooling medium within the water beam, preventing it from flowing out and thus avoiding media waste. Furthermore, the seal facilitates the connection of the cooling medium inlet and outlet to the cooling medium inlet and outlet, respectively. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0020] refer to Figure 1-4A water beam sealing device for a walking beam furnace includes a frame 1, several fixed water beams 2 disposed within the frame 1, and several movable water beams 3 disposed inside the frame 1 and located between two fixed water beams 2. Several movable water beams 3 are provided, and each movable water beam 3 has a translation frame 7 connected to its bottom end. Both the fixed water beams 2 and the movable water beams 3 are provided with cooling medium inlets 4 and cooling medium outlets 8. Each cooling medium inlet 4 and cooling medium outlet 8 is provided with a sealing element 5, and a sealing cap is threaded to the bottom end of the sealing element 5. The device includes an outer cover 51 connected to the cooling medium inlet 4 and the cooling medium outlet 8, a conical platform 52 disposed inside the outer cover 51 and located below the outer cover 51, and an annular body 53 disposed inside the outer cover 51 and located above the outer cover 51. A retainer 54 is disposed on the inner side of the annular body 53, and a flow gap 55 is left between the retainer 54 and the annular body 53. A sealing ball 57 is disposed inside the outer cover 51 and between the retainer 54 and the conical platform 52. A return spring 56 is disposed between the retainer 54 and the sealing ball 57, and the return spring 56 is connected to the retainer 54.

[0021] The cooling medium inlet allows the medium to be used to be input into the fixed water beam 2 or the movable water beam 3, while the cooling medium outlet 8 allows the used medium to be output. The sealing element 5, in conjunction with the sealing cover, achieves a double sealing structure for the cooling medium inlet 4 and the cooling medium outlet 8. This double sealing structure effectively prevents medium leakage. Specifically, the sealing element 5 effectively seals the cooling medium in the water beam, preventing it from flowing out and thus avoiding waste. Furthermore, the sealing element 5 facilitates the connection of the cooling medium input component and the cooling medium recovery component to the cooling medium inlet 4 and the cooling medium outlet 8, respectively.

[0022] Specifically, regarding the cooling medium input principle, the operator connects the cooling medium input component to the sealing component 5. During the continuous input of the cooling medium, the cooling medium exerts a pushing force on the sealing ball 57 through the conical platform 52, causing the sealing ball 57 to move upward. The sealing ball 57 compresses the return spring 56. At this time, the cooling medium passes through the sealing component 5 and the retainer 54 in sequence and enters the cooling medium injection port 4, where it circulates within the fixed water beam 2 or the movable water beam. When the medium input stops, the pressure on the sealing ball 57 and the return spring 56 disappears. At this time, the return spring 56 resets, causing the sealing ball 57 to abut against the conical platform 52, thus completing the sealing work of the conical platform 52. In this state, the cooling medium output channel is closed.

[0023] Specifically, the cooling medium output principle is the same as the cooling medium input principle; when the cooling medium stops continuous input or output, the return spring 56 will reset and seal the cooling medium inside the water beam.

[0024] In this embodiment, the cooling medium includes water vapor or water, etc.

[0025] In this embodiment, during the placement of the fixed water beam 2 and the movable water beam 3, the pressure on the return spring 56 is greater than the pressure of the cooling medium reserved in the fixed water beam 2 or the movable water beam 3. During the injection of the cooling medium, as the cooling medium is continuously injected, the pressure of the cooling medium on the return spring gradually increases, causing the return spring 56 to gradually retract and complete the injection of the cooling medium.

[0026] like Figure 2 As shown, the fixed water beam 2 includes a first support frame 21, two first side columns 22 disposed below the first support frame 21, and a first central column 23 disposed between the two first side columns 22. The first central column 23 is provided with a cooling medium inlet 4 and a cooling medium outlet 8. The first support frame 21, the first side columns 22 and the first central column 23 are all provided with first cooling channels.

[0027] like Figure 3 As shown, the movable water beam 3 includes a second support frame 31, two second side columns 32 disposed below the second support frame 31, and a second central column 33 disposed between the two second side columns 32. The second central column 33 is provided with a cooling medium inlet 4 and a cooling medium outlet 8. The second support frame 31, the second side columns 32 and the second central column 33 are all provided with second cooling channels.

[0028] In this embodiment, the conical platform 52, the annular body 53, and the retainer 54 in the cooling medium inlet 4 and the cooling medium outlet 8 are arranged in opposite directions.

[0029] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0030] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
