Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary installation tools for top-blown furnaces, in particular to an installation and fixing device for an elliptical furnace body enclosure. Background Art

[0002] The oxygen-enriched side-blowing smelting-multi-gun top-blowing continuous blowing-fire anode refining hot three-furnace continuous copper smelting production process has been widely promoted and applied in recent years. It is a copper smelting process with independent intellectual property rights in my country. The process has outstanding advantages, mainly strong adaptability to fluctuations in the copper metal content in the raw materials, and no strict requirements on the input fuel and the water content of the original ore. Its process flow is relatively short, which is suitable for smelting production enterprises with many sources of domestic copper mine supply to choose this process, and the production cost of this process is low and has a price advantage. The side-blowing smelting furnace and the top-blowing blowing furnace are the core equipment of this process. The copper concentrate is fed into the side-blowing smelting furnace through a belt, and oxygen-enriched air is blown into the side-blowing smelting furnace through multiple wind eyes on both sides, so that the copper concentrate completes the process of self-heating smelting in the furnace. The copper matte produced by the smelting furnace flows into the top-blowing blowing furnace through the chute from the siphon port of the side-blowing smelting furnace. The oxygen-enriched air is sprayed into the furnace through multiple oxygen lances extending from the top of the furnace to stir the molten pool and complete the blowing. Flux, residual electrodes and other materials are added through the charging port located on the top of the furnace.

[0003] When installing the furnace body of a top-blown furnace, the furnace body enclosure must be constructed. The installation of the elliptical furnace body enclosure is an important part of the furnace body construction. However, the furnace body enclosure is large in size and is usually made in a factory workshop, divided into four small pieces and then transported to the construction site for assembly, welding and construction. However, during the transportation and installation process, large enclosures are prone to deformation, which will result in large precision deviations during on-site installation, affecting construction quality and efficiency. Therefore, how to prevent the furnace body enclosure from deformation has become a problem that needs to be solved during the installation process. At present, there is no finished product of the elliptical furnace body enclosure reinforcement device on the market. Utility Model Content

[0016] The following will be combined with the accompanying drawings of the utility model to clearly and completely describe the technical solution of the utility model. It is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. In the description of the utility model, it should be noted that the terms "upper", "lower", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when used, which is only for the convenience of describing the utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0017] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" 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 an indirect connection through an intermediate medium, or it can be the internal communication 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.

[0018] See also Figure 1 , Figure 2 The utility model is an elliptical furnace body enclosure installation and fixing device, including a reinforced main bracket 3, on which a plurality of parallel cross arm supports 1 are arranged, all of which are arranged perpendicular to each other between the reinforced main brackets, and the lines formed by the outer ends of all the cross arm supports are in the shape of an outwardly convex elliptical arc, and are consistent with the arc in the corresponding top-blown furnace body enclosure 4.

[0019] Furthermore, the reinforced main support described in this embodiment is formed by butt welding two channel steels, and a butt weld is formed at the welding point, and the cross arm support is made of 16# channel steel. Furthermore, the cross arm support described in the utility model is also made of 16# channel steel, and the outer end of each cross arm support is set to an arc shape that matches the side of the top-blown furnace body enclosure. Further, the outer ends of all cross arm supports in the utility model form an elliptical arc shape, and the formed elliptical arc shape is symmetrically arranged on the left and right sides. Further, the inner ends of all cross arm supports in the utility model are welded to the reinforced main support.

[0020] like Figure 2 As shown, the elliptical top-blown furnace body enclosure 4 is relatively large in size, extra long and extra wide, and the furnace body enclosure needs to be divided into 4 pieces, of which the upper and lower sides are two long sides, and the left and right sides are two short sides. After the elliptical furnace body enclosure is processed into an arc shape, the inner side surfaces of the long arc and short arc enclosures are spot-welded and fixed using the enclosure installation and fixing device of the present invention, and the upper and lower layers are reinforced to prevent the formed enclosure from deforming during transportation and installation. Each elliptical furnace body enclosure has a total of 8 enclosure installation and fixing devices of the present invention (upper and lower layers), and the distance from the fixing device to the enclosure weld position is 150mm.

[0021] After the furnace body enclosure is manufactured in the factory, it is shaped using the enclosure installation and fixing device of the present invention. Each enclosure is transported separately to the installation construction site. After arriving at the site, it is assembled and welded into an integral oval shape. After all the enclosures are welded, the connection between the enclosure installation and fixing device and the enclosure is cut off.

[0022] like Figure 2 As shown, taking the long side panel of the elliptical furnace body plus fixed device as an example, it is welded by the reinforcement main bracket 3 and the cross arm support, and the channel steel model is 16# channel steel. After the four elliptical panels are pre-assembled, the reinforcement main bracket is welded first, which is composed of two 16# channel steels butt-welded. The butt weld is shown in (serial number 2). Then the reinforcement main bracket is divided into equal parts by marking, and the distance between each point and the elliptical panel is measured. The cross arm support is cut according to the measured size. One end of the cross arm support is welded to the reinforcement main bracket and the other end is welded to the side wall of the panel. The processing and manufacturing method of the short side panel reinforcement device is the same as that of the long side panel reinforcement device.
