Description

Technical Field

[0001] The utility model relates to the technical field of installation tools for top-side-blown furnaces in the non-ferrous copper smelting industry, in particular to an auxiliary support frame for installing a hanging type ascending flue. 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] Both the side-blown furnace and the top-blown furnace are designed with a suspended ascending flue. The flue gas in the furnace is discharged from the smoke outlet on the top of the furnace and enters the waste heat boiler through the ascending flue. After the waste heat of the flue gas is recovered, it is discharged after dust removal, desulfurization and denitrification. However, the ascending flue of the top-blown furnace is usually several meters high and has a long length. Its installation adopts a suspended installation method. The hanging installation at high altitude has a greater operation risk. At the same time, the installation quality cannot be guaranteed and the installation period is relatively long. Therefore, it is necessary to design a relatively safe and efficient installation auxiliary tool to help improve the installation efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide an auxiliary support frame for installing a hanging ascending flue in view of the above situation. The auxiliary support frame has a simple structural design and is easy to use and operate.

[0005] The specific scheme of the utility model is: a hanging type ascending flue installation auxiliary support frame, including a long support rod, a short support rod, two connecting cross rods, two reinforcing columns and four adjustment blocks, the long support rod and the short support rod are arranged parallel to each other, the long support rod and the short support rod are connected to form an integral frame by two connecting cross rods, two reinforcing columns are vertically welded on the long support rod, and during installation, the top ends of the two reinforcing columns are welded and connected to the platform beam above the top-blown furnace, and the four adjustment blocks are respectively placed on the long support rod and the short support rod.

[0006] Furthermore, the long support rod and the short support rod described in the utility model are both made of I-beams.

[0007] Furthermore, in the utility model, the two connecting cross bars are arranged symmetrically on the left and right, and the two reinforcing columns are respectively arranged at the intersection of the two connecting cross bars and the long support rods.

[0008] Furthermore, a plane block is also provided at the top end of the reinforcing column in the utility model, and the upper end surface of the plane block is kept flush with the upper end surface of the reinforcing column.

[0009] The utility model overcomes the problems of difficult installation, many high-altitude operations, high difficulty in hoisting operations, and heavy welding workload, ensuring the smooth installation of the flue, reducing the safety risks during the installation process, ensuring the installation quality, and shortening the installation period. It has a good reference effect on the installation of the same type of suspended rising flues, and the specific beneficial effects are:

The structure is stable and the force is stable. The flue skirt can be directly placed on the support frame. Compared with temporary hanging with steel wire rope, it has better stability and safety.

[0011] 2. On the upper surface of the auxiliary support frame, according to the outer dimensions of the flange edge at the bottom of the ascending flue, select a point at each of the four corners of the support frame and set an adjustment block. Adjust the height of the adjustment block according to the design elevation of the ascending flue and the elevation difference of the support frame. At the same time, mark the vertical and horizontal center lines of the ascending flue on the support frame so that the subsequent flue skirt can be hoisted into place at one time, ensuring the installation accuracy of the ascending flue.

[0017] 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.

[0018] 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.

[0019] See also Figure 1 to Figure 4 The utility model is a hanging type ascending flue installation auxiliary support frame, including a long support rod 2, a short support rod 5, two connecting cross bars 4, two reinforcing columns 3 and four adjustment blocks 6. The long support rod and the short support rod are arranged parallel to each other, and the long support rod and the short support rod are connected to form an integral frame through two connecting cross bars. The two reinforcing columns are vertically welded on the long support rod. During the installation operation, the top ends of the two reinforcing columns are welded and connected to the platform beam above the top-blown furnace, and the four adjustment blocks are respectively placed on the long support rod and the short support rod. Further, the long support rod and the short support rod described in the utility model are both made of I-beams. Further, the two connecting cross bars described in the utility model are arranged symmetrically on the left and right, and the two reinforcing columns are respectively arranged at the intersection of the two connecting cross bars and the long support rod. Further, the top end of the reinforcing column described in the utility model is also provided with a plane block 7, and the upper end surface of the plane block is kept flush with the upper end surface of the reinforcing column.

[0020] The main reason for using the reinforcing column in the utility model is that the long support rod is relatively long and has a large span, and is easy to deform when supporting the installation of the flue skirt, which affects the installation accuracy and safety. Therefore, a reinforcing column is installed here and hoisted on the upper beam to prevent the long support rod from being deformed and affecting the installation construction. After the flue skirt is installed, it can be cut off.

[0021] The auxiliary support frame of the utility model is placed on the furnace frame 1 structure, and two reinforcement columns are added to connect with the structural beam above the furnace top. The structure is stable and the force is stable. The flue skirt can fall directly on the support frame. Compared with temporary hanging with steel wire rope, the stability and safety are better.

[0022] On the upper surface of the auxiliary support frame, according to the outer dimensions of the flange edge at the bottom of the ascending flue, an adjustment block is set at a point at each of the four corners of the support frame. The height of the adjustment block is adjusted according to the design elevation of the ascending flue and the elevation difference of the support frame. At the same time, the vertical and horizontal center lines of the ascending flue are marked on the support frame so that the subsequent flue skirt can be hoisted into place at one time, ensuring the installation accuracy of the ascending flue.

[0023] The utility model discloses an auxiliary support frame for installing a suspended rising flue, which overcomes the problems of difficult installation, many high-altitude operations, difficult lifting operations, and heavy welding workload. It ensures the smooth installation of the flue, reduces the safety risks during the installation process, ensures the installation quality, shortens the installation period, and serves as a good reference for the installation of similar suspended rising flues.
