Description

Technical Field

[0001] This utility model relates to the field of molten steel jackets for metallurgical furnaces and kilns, and in particular to a molten steel jacket assembly for an easy-to-replace slag skimmer. Background Technology

[0002] In the copper smelting industry, steel jackets are frequently used in smelting equipment, such as at the opening of anode furnaces and flue openings. They are generally located at openings, such as slag skimmers.

[0003] The molten steel jacket is susceptible to heat deformation due to the high heat, which can lead to deformation of the anode furnace opening and flue opening later on, affecting the quality of furnace brick replacement and maintenance, as well as the quality of furnace brick laying. Utility model patent CN221544714U discloses a molten steel protective jacket, which includes a molten steel jacket mold and a heat dissipation plate. The two are connected by a fastening device, but the fastening connection is also prone to heat deformation, making it difficult to disassemble the molten steel jacket mold and the heat dissipation plate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a slag removal port steel jacket assembly that is easy to replace, and to solve the problem that the connection between the steel jacket and the heat sink plate is also prone to heat deformation, which makes disassembly difficult.

[0005] To solve the above-mentioned technical problems, this utility model provides a molten steel jacket assembly with an easy-to-replace slag removal port, including a molten steel jacket mold, a heat dissipation plate disposed below the molten steel jacket mold, a first connecting plate disposed on one side of the heat dissipation plate, a corresponding second connecting plate disposed on one side of the molten steel jacket mold, connecting holes disposed on the first connecting plate and the second connecting plate, bolts for connecting the molten steel jacket mold and the heat dissipation plate disposed in the connecting holes, and a heat dissipation mechanism disposed inside the heat dissipation plate, the heat dissipation mechanism extending to the connecting hole of the first connecting plate.

[0006] In a preferred embodiment, the heat dissipation mechanism includes a first connector located on the inlet side of the heat dissipation plate and a second connector located on the outlet side. An S-shaped curved water supply pipe is connected between the first connector and the second connector, with the water supply pipe curving around the connection hole.

[0007] In a preferred embodiment, a groove matching the water supply pipe is provided inside the heat sink.

[0008] In the preferred embodiment, the first connector has a flared opening inside.

[0009] In a preferred embodiment, a perforated baffle is provided in front of the flared opening, a filter screen is provided in front of the baffle, a T-shaped protrusion is provided behind the baffle, and a scale brush is provided inside the water supply pipe, which is connected to the T-shaped protrusion by a thin rope.

[0010] In the preferred embodiment, the thin rope is made of metal; the steel molten steel mold and the heat sink are also made of metal.

[0011] The beneficial effects of this utility model are as follows: Because this utility model provides a slag removal port steel jacket assembly that is easy to replace, a connection hole is provided between the steel jacket mold and the heat dissipation plate, and a heat dissipation mechanism is provided between the two. The heat dissipation mechanism extends to the connection hole, thereby dissipating heat around the connection hole and preventing large misalignment and deformation between the steel jacket mold and the heat dissipation plate, which would affect the disassembly of the steel jacket mold and the heat dissipation plate.

[0017] Please see Figure 1-3 As shown, this application provides a technical solution: a replaceable slag removal port molten steel jacket assembly, including a molten steel jacket mold 11, a heat dissipation plate 12 disposed below the molten steel jacket mold 11, a first connecting plate 13 disposed on one side of the heat dissipation plate 12, a corresponding second connecting plate 14 disposed on one side of the molten steel jacket mold 11, connecting holes 131 disposed on the first connecting plate 13 and the second connecting plate 14, bolts 15 for connecting the molten steel jacket mold 11 and the heat dissipation plate 12 disposed in the connecting holes 131, and a heat dissipation mechanism disposed inside the heat dissipation plate 12, the heat dissipation mechanism extending to the connecting holes 131 of the first connecting plate 13.

[0018] In a preferred embodiment, the heat dissipation mechanism includes a first connector 21 located on the inlet side of the heat dissipation plate 12 and a second connector 22 located on the outlet side. An S-shaped curved water pipe 23 is connected between the first connector 21 and the second connector 22, with the water pipe 23 curving around the connection hole 131.

[0019] The steel jacket mold 11 is lined with refractory material, making it more durable. This allows the water pipe 23 to wrap around the connection hole 131, carrying away heat from the area around the connection hole 131 and preventing misalignment or deformation of the steel jacket mold 11 and the heat sink 12 above the connection hole, which could lead to difficulties in disassembling the bolts 15.

[0020] In a preferred embodiment, a groove matching the water pipe 23 is provided inside the heat sink 12.

[0021] In this way, the water pipe 23 can be placed in the groove, and the water pipe 23 can also make full contact with the heat sink 12, thereby increasing the contact area for heat exchange.

[0022] In the preferred embodiment, the first connector 21 has a flared opening 211 inside.

[0023] The first connector 21 and the second connector 22 can be standard parts that can be purchased directly, such as connectors from SMC. The flared end 211 is also a structure that comes with the connector or can be processed later.

[0024] In a preferred embodiment, a perforated baffle plate 24 is provided in front of the flared mouth 211, a filter screen 25 is provided in front of the baffle plate 24, a T-shaped protrusion 26 is provided behind the baffle plate 24, and a scale brush 27 is also provided inside the water supply pipe 23. The scale brush 27 is connected to the T-shaped protrusion 26 by a thin rope 28.

[0025] By connecting the scale brush 27 and the baffle plate 24 together, when there is a lot of scale inside the water pipe 23, the baffle plate 24 can be removed, and the thin rope 28 can be pulled. The thin rope 28 pulls the scale brush 27, causing the scale brush 27 to move inside the water pipe 23 and scrape off the scale. When it is not necessary to scrape the scale, the scale brush 27 can be left at the second connector 22.

[0026] In use, the first connector 21 and the second connector 22 are connected to an external circulating water circuit to form a heat dissipation cycle.

[0027] In a preferred embodiment, the string 28 is made of a metallic material, such as steel wire. The molten steel sleeve mold 11 and the heat sink 12 are also made of metallic materials.

[0028] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
