Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical equipment processing technology, specifically to a tooling for manufacturing a gas distribution system for a roasting furnace. Background Technology
[0002] In pyrometallurgical lead-zinc smelting projects, the gas distribution system of the roasting furnace plays a crucial role. This system encompasses key components such as ducts, air distributors, and air caps. Its core function is to achieve uniform gas distribution, thereby promoting material fluidization and effectively preventing material accumulation. Simultaneously, it increases the contact area between the material and the gas, accelerating the reaction process, regulating the fluidization state to avoid abnormal phenomena, helping to maintain heat balance, and facilitating material transport and mixing. In actual operation, the ducts are responsible for introducing air and evenly distributing it to the air caps on the air distributor. The air is then released into the furnace through small holes in the air caps, ensuring that the zinc concentrate particles are uniformly suspended, thus enabling the roasting reaction to proceed.
[0003] However, the installation of air distribution panels and hoods currently faces numerous stringent requirements. Air distribution panels must remain flat and airtight, and their installation position and dimensions require high precision. For hoods, the installation position must be accurate and secure, while also ensuring verticality and linearity, and achieving a tight fit with the air distribution panel. These complex requirements pose significant challenges to manufacturing and installation, making the entire process time-consuming and labor-intensive. There is an urgent need to develop a specialized tool capable of precise and efficient installation and manufacturing of air distribution panels and hoods. Utility Model Content
[0004] This invention aims to address the installation difficulties of the air distribution plate and air cap mentioned in the background art by providing a practical tooling for manufacturing a gas distribution system for a roasting furnace, thereby optimizing the installation process and improving operational efficiency.
[0005] The tooling for manufacturing the gas distribution system of the roasting furnace of this utility model is characterized in that the tooling includes a base plate, vertical plates, clamping plates, and pressure plates: the base plate is provided with a plurality of circular grooves, the diameter and distribution position of the circular grooves are consistent with the circular holes on the air distribution plate of the roasting furnace; a plurality of vertical plates are arranged side by side on the base plate, the tops of the vertical plates are located on the same horizontal plane; clamping plates are provided at corresponding positions on both sides of the base plate, the clamping plates are provided with vertical grooves, and rectangular pressure plates are placed in the grooves, and the pressure plates move up and down along the grooves.
[0006] Ideally, stiffening plates are provided between the uprights, and these stiffening plates are connected to both the uprights on both sides and the bottom plate to prevent the uprights from tilting under stress.
[0007] Ideally, the tooling for manufacturing the gas distribution system of the roasting furnace also includes a wedge. The wedge is triangular and is inserted into the groove above the pressure plate during use, so that the air distribution plate and the top of the vertical plate are tightly fitted to ensure installation accuracy.
[0008] This utility model discloses a tooling for fabricating a gas distribution system for a roasting furnace. With its simple and practical structure, it simultaneously ensures the welding precision between adjacent air distribution pipes and between the air distribution pipes and the air caps, fully meeting the process requirements of the gas distribution system for the roasting furnace. Practical application has verified that this tooling significantly improves installation efficiency and reduces manual labor intensity, demonstrating high practical value and warranting widespread application within the industry.

[0012] Example 1: A tooling for fabricating a gas distribution system for a roasting furnace, comprising a base plate 1, vertical plates 2, clamping plates 3, and pressure plates 4: Several circular grooves are provided on the base plate 1, and the diameter and distribution of the circular grooves are consistent with the circular holes on the air distribution plate of the roasting furnace; Several vertical plates 2 are arranged side by side on the base plate 1, and the tops of the vertical plates 2 are located on the same horizontal plane. Ribs 5 are provided between the vertical plates 2, and the ribs 5 are connected to both sides of the vertical plates 2 and the base plate 1; Clamping plates 3 are provided at corresponding positions on both sides of the base plate 1, and vertical grooves are provided on the clamping plates 3. Rectangular pressure plates 4 are placed in the grooves, and the pressure plates 4 move up and down along the grooves. In use, several air distribution plates are placed on the fixture for the gas distribution system of the roasting furnace, with adjacent air distribution plates placed close together to ensure that all air distribution plates to be connected are always on the same horizontal plane. Then, the air distribution plates are fixed with pressure plate 4. The fixture also includes wedges 6, which are triangular. After the wedges 6 are inserted into the groove at the top of the pressure plate 4, they are inserted into the groove to press the air distribution plates together. Then, the adjacent air distribution plates are welded to ensure their flatness. Air caps are inserted into the round holes of the air distribution plates. At the same time, the air caps are inserted into the round grooves on the corresponding bottom plate 1 and abut against the bottom surface of the round grooves to prevent the air caps from shaking. The operator visually observes that the air caps are all vertical and that the tops are at the same height without shaking before the air distribution plates and air caps are welded together.
