Abstract
Description
Technical Field
[0001] This application belongs to the field of side-blown furnace technology, and more specifically, relates to a regulating valve plate device for the feed hopper discharge port of a side-blown furnace. Background Technology
[0002] The existing side-blown furnace has its feed inlets located at the top of the copper or steel jacket. There are usually two or more feed inlets, which are connected to feeding hoppers via pipes. A belt conveyor is installed above the feeding hoppers to feed materials into them. The materials in the feeding hoppers then flow into the corresponding feed inlets through various pipes. In this process, the amount of material entering through each pipe is uncontrollable. Some pipes have a large amount of material entering, while others have a small amount, which is not conducive to the processing of materials by the side-blown furnace. Utility Model Content
[0003] In view of the problem that the material intake of each pipe cannot be adjusted in the feeding hopper of the prior art, the purpose of this application is to provide a regulating valve plate device for the feeding port of a side-blown furnace feeding hopper, which can adjust the material intake of each pipe and is simple and convenient to operate.
[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a regulating valve plate device for the feeding port of a side-blown furnace feeding hopper is provided, comprising: pipes and a feeding hopper, the number of pipes being the same as the number of feeding ports on the side-blown furnace, at least two pipes, one end of each pipe being connected to a feeding port and the other end being connected to the bottom of the feeding hopper, an regulating plate being rotatably provided inside the feeding hopper, the regulating plate being located between the two pipes, an operating rod being provided on the regulating plate, and a limiting plate being provided on the feeding hopper, the operating rod driving the regulating plate to rotate to a predetermined angle and then engaging with the limiting plate.
[0005] In one embodiment, the limiting plate is provided with a row of spaced-apart slots, which engage with the operating lever.
[0006] In one embodiment, a handheld end is provided at the end of the operating lever away from the adjustment plate, and the handheld end is not linearly aligned with the operating lever.
[0007] In one embodiment, the adjusting plate is rotatably disposed inside the feeding hopper via a rotating shaft.
[0008] In one embodiment, the operating lever is rotatably connected to the adjusting plate by bolts.
[0009] In one embodiment, the pipe is provided with a drain pipe, and the opening of the drain pipe is provided with a sealing cap.
[0010] In one embodiment, the sealing cap is provided with a handle.
[0011] In one embodiment, all the pipes are steel pipes, and the adjusting plate, operating lever and limiting plate are all steel components.
[0012] In one embodiment, three pipes are provided, two adjusting plates are provided, two operating rods are provided, and two limiting plates are provided, with each limiting plate used to limit one of the operating rods.
[0013] The beneficial effect of the regulating valve plate device for the feed hopper of a side-blown furnace provided in this application is that: by setting a regulating plate inside the feed hopper, the material falls through the regulating plate first, thus the regulating plate can adjust the amount of material entering each pipe when it falls, thereby playing a regulatory role. The adjustment position of the regulating plate is limited by a limiting plate, which has the advantages of simple operation and convenient adjustment. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0024] like Figures 1-3 As shown in the illustration, a regulating valve plate device for the discharge port of a side-blown furnace charging hopper provided in this application embodiment will now be described. This regulating valve plate device for the discharge port of a side-blown furnace charging hopper includes: pipes 2, a charging hopper 3, a regulating plate 4, an operating lever 5, and a limiting plate 6. The number of pipes 2 is the same as the number of inlets 1 on the side-blown furnace, with at least two pipes 2. One end of each pipe 2 is connected to an inlet 1, and the other end is connected to the bottom of the charging hopper 3. Both ends of each pipe 2 are connected to the inlet 1 and the charging hopper 3 respectively by welding.
[0025] The adjusting plate 4 is rotatably mounted inside the feeding hopper 3, positioned between the two pipes 2. When the adjusting plate 4 is tilted towards a particular pipe 2, the amount of material passing through that pipe 2 is reduced, thus regulating the material flow rate within the pipe 2. One end of the operating lever 5 is connected to the adjusting plate 4, and the other end extends from the upper end of the feeding hopper 3. The operator uses the operating lever 5 to rotate the adjusting plate 4. A limiting plate 6 is located at the upper end of the feeding hopper 3, restricting the position of the operating lever 5. During adjustment, the operator rotates the adjusting plate 4 to a predetermined angle using the operating lever 5, causing the operating lever 5 to engage with the limiting plate 6, ensuring the adjusting plate 4 remains stably in its current position.
[0026] For ease of adjustment, the limiting plate 6 is a toothed plate with a row of spaced-apart slots 61. Each slot 61 can engage with the operating lever 5. One end of the operating lever 5 is rotatably mounted on the adjusting plate 4, and the other end is a handheld end 51. During operation, the operator holds the handheld end 51, first pushes the operating lever 5 out of the slot 61, then rotates the adjusting plate 4 to the predetermined position, and then engages the operating lever 5 into another corresponding slot 61 to limit the position of the adjusting plate 4.
[0027] The handheld end 51 is positioned away from the adjusting plate 4 and extends out of the feeding hopper 3. The handheld end 51 is not aligned with the operating rod 5. The angle between the handheld end 51 and the operating rod 5 is preferably an obtuse angle. This way, when the operating rod 5 is engaged with the limiting plate 6, the handheld end 51 extends horizontally to the side of the feeding hopper 3, making it convenient for the staff to hold.
[0028] In this embodiment, the bottom edge of the adjusting plate 4 is rotatably mounted inside the feeding hopper 3 via a rotating shaft 41. The operating rod 5 is connected to the top edge of the adjusting plate 4; specifically, the operating rod 5 is rotatably connected to the adjusting plate 4 via bolts 52. The end of the operating rod 5 is U-shaped, and after being inserted into the adjusting plate 4, it is rotatably connected by bolts 52 passing through it.
[0029] In this embodiment, since there is a certain distance between the multiple inlets 1, and some of the multiple pipes 2 are inclined, a dredging pipe 7 is provided on the pipe 2, and a sealing cap 71 is provided at the opening of the dredging pipe 7. When the sealing cap 71 is opened, the worker can use a steel bar to insert into the pipe 2 through the dredging pipe 7 to dredge the material in the pipe 2. To facilitate opening the sealing cap 71, a handle 72 is provided on the sealing cap 71. The sealing cap 71 is made of steel.
[0030] Since the side-blown furnace generates high temperatures, in this embodiment, all pipes 2 are steel pipes 2, and the adjusting plate 4, operating rod 5 and limiting plate 6 are all steel components to ensure normal operation in high-temperature environments.
[0031] In one specific implementation, three pipes 2 are provided, two adjusting plates 4 are provided, two operating rods 5 are provided, and two limiting plates 6 are provided. Each limiting plate 6 is used to limit one operating rod 5. During adjustment, the two adjusting plates 4 can be tilted towards the middle, and the distance between the two adjusting plates 4 is the material inlet channel of the middle pipe 2. In this way, the material delivered by the belt conveyor will be divided into three parts and flow into the three pipes 2 respectively.
[0032] In practice, the outer side of the feeding hopper 3 is equipped with a support flange 31, which is supported by four L-shaped angle steels. Multiple spaced stiffeners 32 are installed on the L-shaped angle steels to improve load-bearing capacity. A first concrete beam 8 (or steel beam) is installed inside the plant. The support flange 31 is installed on the first concrete beam 8 to support the feeding hopper 3. Similarly, if some pipes 2 are inclined, a second concrete beam 9 is installed below the inclined pipe 2. A support base plate 91 is fixed to the second concrete beam 9 by expansion bolts 52. Support rods 92 are welded to the support base plate 91 and welded to the pipe 2, thus supporting the pipe 2.
[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
