Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere electric slag furnaces, in particular to a tool for disassembling an insulating sealing ring of a smoke hood of an atmosphere electric slag furnace. Background Art

[0002] An insulating seal ring is fixedly installed in the upper smoke hood of the electroslag atmosphere furnace through a flange. The conductive rod passes through the insulating seal ring. The inner side of the insulating seal ring is in close contact with the conductive rod. When the conductive rod moves, the insulating seal ring plays the role of insulation and sealing. During the smelting process of the atmosphere furnace, the conductive rod moves downward at a uniform speed until the parent material is melted. Due to the large amount of dust in the atmosphere furnace, after a period of operation, there will be dust accumulation between the insulating seal ring and the rod, resulting in the rod moving blocked, causing abnormal smelting process curves, and the surface quality of the ingot does not meet the requirements. Therefore, it is necessary to clean the dust accumulation in the seal ring in time to eliminate the blocking phenomenon.

[0003] At present, in order to thoroughly clean the accumulated dust, the conductive rod needs to be pulled out so that the conductive rod is separated from the upper smoke hood, and then the insulating sealing ring can be taken out for cleaning. This is a large workload and affects the production time for a long time. Utility Model Content

[0027] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a tool for disassembling the insulating sealing ring of the smoke hood of an atmosphere electric slag furnace. The disassembly tool is installed on the conductive material rod 1 of the atmosphere electric slag furnace, and is used to move toward the smoke hood together with the conductive material rod 1 to push the insulating sealing ring in the smoke hood out of the smoke hood; the disassembly tool includes a sleeve 2, a sleeve 2 3 and a connecting mechanism, and the sleeve 1 2 and the sleeve 2 3 are both arc-shaped plates; when the sleeve 1 2 and the sleeve 2 3 are attached to the side of the conductive material rod 1, the axis of the sleeve 1 2, the axis of the sleeve 2 3 and the axis of the conductive material rod 1 are collinear; when the sleeve 1 2 and the sleeve 2 3 are attached to the side of the conductive material rod 1, the sleeve 1 2 and the sleeve 2 3 are connected by the connecting mechanism.

[0029] In this embodiment, when cleaning the dust accumulation between the conductive rod 1 and the insulating seal ring, the conductive rod 1 is controlled to drop to a position 20 mm from the bottom of the atmosphere furnace, and then the flange of the insulating seal ring is disassembled at the upper part of the upper smoke cover, and then the clamping sleeve 1 2 and the clamping sleeve 2 3 are set and fixed at the position near the bottom of the conductive rod 1 by using the connecting mechanism. Then the conductive rod 1 is controlled to rise slowly, and the upper end surfaces of the clamping sleeve 1 2 and the clamping sleeve 2 3 push the seal ring out of the upper furnace cover from bottom to top, and finally the insulating seal ring is cut into half by a cutting machine, so that the insulating seal ring can be easily taken out and reinstalled, and the dust cleaning work is simple and fast, with a small workload, and there is no need to take out the conductive rod 1, which shortens the time required for dust cleaning.

[0030] In addition, the insulating sealing rings used subsequently all use insulating sealing rings composed of two half rings, and there is no need to cut the insulating sealing rings.

[0031] As a preferred embodiment, Figure 1 and Figure 2 As shown, the ferrule 1 2 and the ferrule 2 3 are exactly the same, and both of them are arc-shaped plates, and their top surfaces are flat. The conductive rod 1 drives the disassembly tool to move upward, and the conductive rod 1 slowly passes through the insulating sealing ring, so that the ferrule 1 and the ferrule 2 3 gradually approach the insulating sealing ring, and finally the top surfaces of the ferrule 1 and the ferrule 2 3 press against the lower surface of the insulating sealing ring and push the insulating sealing ring upward to move out of the upper smoke cover.

[0032] It should be noted that there is an annular tray inside the upper smoke hood, the inner diameter of the annular tray is larger than the inner diameter of the insulating sealing ring, and the insulating sealing ring is placed on the tray, that is, only a part of the insulating sealing ring falls on the tray, and the part of the insulating sealing ring close to the inner ring does not contact the tray. Further, the distance between the inner side of the tray and the conductive material rod 1 is larger than the thickness of the ferrule 1 2 and the ferrule 2 3, so that when the conductive material rod 1 drives the disassembly tool to move upward, the upper end surfaces of the ferrule 1 2 and the ferrule 2 3 can pass through the tray and act on the lower surface of the insulating sealing ring.

[0033] Preferably, the connecting mechanism includes a first fixing plate 201, a second fixing plate 301 and a bolt 4, wherein the first fixing plate 201 is installed at the bottom of the side of the ferrule 1 2, and the second fixing plate 301 is installed at the bottom of the side of the ferrule 2 3, and the first fixing plate 201 and the corresponding second fixing plate 301 are fixed by bolts 4.

[0034] Specifically, Figure 2 As shown, a first fixing plate 201 is installed at the bottom of the left side of the ferrule 1 2, and a first fixing plate 201 is also installed at the bottom of the right side of the ferrule 1 2. A second fixing plate 301 is installed at the bottom of the left side and the bottom of the right side of the ferrule 2 3. The first fixing plate 201 at the bottom of the left side of the ferrule 1 2 and the second fixing plate 301 at the bottom of the left side of the ferrule 2 3 are fixed by bolts 4, and the second fixing plate 301 at the bottom of the right side of the ferrule 2 3 and the second fixing plate 301 at the bottom of the right side of the ferrule 2 3 are fixed by bolts 4.

[0035] It needs to be explained that the connection mechanism is set at a position close to the bottom of the ferrule 1 2 and the ferrule 2 3 in order to prevent the connection mechanism from hindering the insertion of the ferrule 1 2 and the ferrule 2 3 into the upper smoke hood.

[0036] It should be noted that circular holes are provided on the first fixing plate 201 and the second fixing plate 301. After the ends of the bolts 4 pass through the circular holes on the first fixing plate 201 and the second fixing plate 301 in turn, nuts are screwed on the ends of the bolts 4, and the ferrules 1 2 and ferrules 2 3 are clamped on the conductive material rod 1 by tightening the nuts.

[0037] It should be noted that the inner side and the side surfaces of the ferrule 1 2 and the ferrule 2 3 need to be ground and polished to prevent the ferrule 1 2 and the ferrule 2 3 from damaging the conductive rod 1 .

[0038] Preferably, the first fixing plate 201 and the second fixing plate 301 are both in the shape of angle irons, the first fixing plate 201 is welded to the side of the ferrule 1 2 , and the second fixing plate 301 is welded to the side of the ferrule 2 3 .

[0039] Optionally, the first fixing plate 201 and the second fixing plate 301 are both plate-shaped, the first fixing plate 201 and the ferrule 1 2 are integrally formed, and the second fixing plate 301 and the ferrule 2 3 are integrally formed.

[0040] Optional, such as Figure 2 As shown, a protective pad 5 is provided on the inner side surface of the ferrule 1 2 and the inner side surface of the ferrule 2 3. The protective pad 5 is a rubber pad or a plastic pad. Its function is to prevent the ferrule 1 2 and the ferrule 2 3 from directly contacting the conductive material rod 1 and preventing damage to the conductive material rod 1.

[0041] Optional, such as Figure 3 As shown, a first annular sheet 202 is coaxially arranged on the side of the top of the ferrule 1 2, and the upper surface of the first annular sheet 202 is in the same horizontal plane as the top surface of the ferrule 1 2. A second annular sheet 302 is coaxially arranged on the side of the top of the ferrule 2 3, and the upper surface of the second annular sheet 302 is in the same horizontal plane as the top surface of the ferrule 2 3. The width of the first annular sheet 202 is one third of the thickness of the ferrule 1 2, and the width of the second annular sheet 302 is one third of the thickness of the ferrule 2 3.

[0042] In this way, when the ferrule 1 2 and the ferrule 2 3 act on the lower surface of the insulating rubber ring, the upper surfaces of the first annular sheet 202 and the second annular sheet 302 will also act on the lower surface of the insulating rubber ring, which can improve the stability when ejecting the rubber ring.

[0043] As an alternative embodiment, in this embodiment, the first side of the ferrule 1 2 and the first side of the ferrule 2 3 are hingedly connected by a hinge, and the second side of the ferrule 1 2 and the second side of the ferrule 2 3 are connected by a connecting mechanism. In this way, only one connecting mechanism is required, and installation and disassembly are more convenient.

[0044] In the description of the present invention, it should be noted that the terms "upper" and "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the insides of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.
