Description

Technical Field

[0001] The utility model relates to the technical field of silicon-manganese alloys, in particular to a blocking device for smelting silicon-manganese alloys. Background Art

[0002] Silicon manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is a ferroalloy with a wide range of uses and large output. Manganese silicon alloy is a commonly used composite deoxidizer in steelmaking, and is also a reducing agent in the production of medium and low carbon ferromanganese and the production of metallic manganese by the electrosilicothermic method.

[0003] During the smelting of silicon-manganese alloys, plugging devices are often used in high-temperature reactors. During the smelting process, the temperature inside the reactor is extremely high. To prevent molten material or gas from leaking out of the channel or pipe, a plugging device is required to seal or block specific channels or pipes. Currently, the plugging methods used are generally welding or installing plugging plates with screws. The former makes it difficult to remove the welded plates when maintenance is required, or requires external tools to remove a large number of screws before maintenance can be performed. This is not only inconvenient to operate, but also inefficient to install and disassemble. Utility Model Content

[0011] Preferably, the front and rear sides of the sealing shell are fixedly connected with reinforcing ribs, and the right side of the reinforcing ribs is fixedly connected to the smelting furnace.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the user needs to seal the sealing shell, the electric push rod drives the extension plate and the motor to move. At the same time, the motor is driven to drive the transmission rod to drive the cover plate to rotate, so that the thread on the surface of the connecting pipe is connected with the thread in the sealing shell, so that it is rotated into the sealing shell.

[0022] It should be noted that: the driving motor 10 facilitates the transmission rod 11 to drive the cover plate 6 to rotate, so that the connecting pipe 5 spirally enters the inner cavity of the sealing shell 4 for sealing.

[0023] refer to Figure 4 As shown, a first sealing plate 12 is fixedly connected to the right side of the connecting pipe 5, a first sealing groove 13 is provided on the left side of the sealing shell 4 for use with the first sealing plate 12, a second sealing plate 14 is fixedly connected to the right side of the cover plate 6, and a second sealing groove 15 is provided on the left side of the sealing shell 4 for use with the second sealing plate 14.

[0024] It should be noted that when the connecting pipe 5 moves, the first sealing plate 12 will be driven to insert into the inner cavity of the first sealing groove 13, thereby sealing. At the same time, when the connecting pipe 5 moves, the cover plate 6 and the second sealing plate 14 will be driven to insert into the inner cavity of the second sealing groove 15, thereby performing secondary sealing to improve the sealing effect.

[0025] refer to Figure 2 and Figure 3As shown, the front and rear sides of the left bottom of the smelting furnace 1 are fixedly connected to the support rod 16, the left side of the support rod 16 is fixedly connected to the connecting plate 17, the right side of the connecting plate 17 is fixedly connected to the smelting furnace 1, the front and rear sides of the extension plate 8 are fixedly connected to the sliding plate 18, the inner cavity of the sliding plate 18 is slidably connected to the surface of the support rod 16, the front and rear sides of the sealing shell 4 are fixedly connected to the reinforcing rib 19, and the right side of the reinforcing rib 19 is fixedly connected to the smelting furnace 1.

[0027] Working principle: When the user needs to seal the sealing shell 4, the extension plate 8 and the motor 10 are driven to move by the electric push rod 7. When the extension plate 8 moves, the sliding plate 18 is driven to move on the surface of the support rod 16. At the same time, the motor 10 is driven to make the transmission rod 11 drive the cover plate 6 to rotate, so that the thread on the surface of the connecting pipe 5 is connected with the thread inside the sealing shell 4, so that it is rotated into the sealing shell 4. The first sealing plate 12 is inserted into the inner cavity of the first sealing groove 13 to improve the sealing between the connecting pipe 5 and the sealing shell 4. At the same time, the cover plate 6 will drive the second sealing plate 14 to insert into the inner cavity of the second sealing groove 15 for secondary sealing.
