Description

Technical Field

[0001] This invention relates to the field of environmental management technology in mineral resource smelting, specifically to a treatment system for blast furnace slag pits. Background Technology

[0002] A submerged arc furnace, also known as an electric arc furnace or resistance furnace, is primarily used for the reduction smelting of ores, carbonaceous reducing agents, and solvents. After the ore is smelted at high temperatures in the submerged arc furnace, molten iron and slag flow out from the outlet. High-temperature slag, such as blast furnace slag, possesses extremely high heat and pressure at high temperatures, posing safety hazards if handled directly. The submerged arc furnace slag produced during the smelting process mainly consists of mineral residues, unreacted raw materials, and small amounts of metal oxides. These substances undergo melting and reduction processes in the high-temperature environment of the submerged arc furnace, and after cooling, form slag blocks with a certain hardness and wear resistance. Pouring this slag into a slag pit ensures safe cooling and prevents accidents such as explosions. Ferroalloy slag generates a large amount of non-metallic and harmful substances during processing, which are difficult to handle or recycle directly and require pretreatment. Pretreatment mainly involves crushing, screening, and magnetic separation of the cooled slag to remove impurities and ferromagnetic substances; therefore, the cooling and initial crushing of the slag are completed within the slag pit. The waste residue that has undergone initial crushing is then transferred into the crushing equipment for secondary crushing and refinement.

[0003] Existing slag pits are typically constructed at ground level. The inner walls of these pits are built using materials such as high-strength, acid-resistant, and wear-resistant materials, cast stone, and Al2O3-SiC-C iron trough castable. The high-strength, acid-resistant, and wear-resistant material is composed of high-hardness corundum raw materials, with the addition of appropriate amounts of stainless steel fibers and a binder with strong acid corrosion resistance. This greatly enhances the slag pit's corrosion resistance, erosion resistance, high strength, dense structure, and volume stability. Because slag pits require excavation at ground level, they are generally located outside the plant building.

[0004] To limit the flow of waste residue, concrete baffles are embedded around the edges of the slag pit. However, this type of pit lacks the capacity to collect waste residue, requiring a loader to push the waste around its perimeter. Secondly, the baffles have a limited lifespan; after a certain period of use, they need to be replaced and re-buried, a time-consuming process that impacts the pit's usability. Furthermore, during the spray cooling process, cooling water can easily overflow from the gaps in the baffles, potentially affecting the surrounding environment. Therefore, modifying the existing slag pit structure to better suit continuous waste residue treatment while reducing environmental pollution and creating a holistic treatment system is a direction that needs further research and improvement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a slag pit treatment system for submerged arc furnaces. This system changes the traditional operation mode of setting up slag pits on the ground and improves the slag treatment capacity of submerged arc furnaces. During the slag treatment process, wastewater and flue gas are collected to avoid impacting the surrounding environment, forming a continuous operation that is more suitable for modern production operations.

Detailed Implementation

[0033] like Figure 2-7As shown, a submerged arc furnace slag pit treatment system is provided, which requires setup and installation based on a base platform 1. The surface of the base platform 1 is used to support the waste slag. To ensure that the base platform 1 can withstand its high temperature, it is cast using existing pit construction materials, such as high-strength acid-resistant and wear-resistant materials, cast stone, and iron trough castable. Similarly, the baffle 2 also needs to withstand high temperatures, so it should also use the same material as the base platform 1 to ensure that the base platform 1 and the baffle 2 meet the required strength standards. Three edges of the base platform 1 are provided with slots 1.1 for inserting the baffle 2, and a guide port 1.2 is fixed below the other edge. Cooling water entering the three slots 1.1 flows into the guide port 1.2 along the slots 1.1 to facilitate the collection and treatment of the cooling water into the water tank 17.

The inlet and outlet of the water pipes 1.4 are connected to the water tank 17 below the base via pipelines, and a first water pump 6 and a control valve are provided on the pipelines. Cooling water in the water tank 17 can circulate at the bottom of the base platform 1.

Furthermore, to prevent interference between the baffle 2 and the base platform 1 during the flipping process, the bottom of the baffle 2 controlled by the flipping mechanism 3 is provided with a slope structure 2.2 to prevent flipping interference. The base platform 1 is provided with an inclined surface 1.3 below the slope structure 2.2 to prevent interference from the rotation of the baffle 2; the angle between the inclined surface 1.3 and the slope structure 2.2 is greater than 30°.

The second moving seat 512 moves along the second moving rail 511. The first moving seat 412 and the second moving seat 512 have the same structure. The secondary movable plate 513 is fixed between the second moving seats 512. A first track is provided on the ground between the second moving rails 511. The moving trolley 515 moves along the first track. The primary movable plate 514 is fixed on the surface of the moving trolley 515. The primary movable plate 514 is fixed to the end of the connecting rod 516. The connecting rod 516 passes through the secondary movable plate 513 and is fixed to the smoke hood 518. A spray pipe 517 is fixed around the smoke hood 518. Furthermore, the connecting rod 516 is a hollow rod-shaped structure; the water inlet pipe of the spray pipe 517 passes through the inside of the connecting rod 516, and the reserved length of the water inlet pipe is greater than the travel distance of the fume hood 518; the top of the fume hood 518 is connected to the main dust pipe through a metal flexible hose, and the main dust pipe draws in exhaust gas through the negative pressure of the fume hood 518. The metal flexible hose and the water inlet pipe are reserved with sufficient length to ensure that the fume hood 518 can move freely.

[0038] like Figure 1 , 12 As shown, a baffle wall 16 is provided below the first moving rail 411; an opening for placing the liquid inlet chute 13 is provided on the baffle wall 16, and a third moving rail 12 is provided outside the opening of the baffle wall 16; a heat insulation seat 14 is provided on the third moving rail 12; the liquid inlet chute 13 is fixed above the heat insulation seat 14; a second traveling wheel 8 is fixed below the heat insulation seat 14, and the second traveling wheel 8 is driven by a second traveling motor 9; after the liquid inlet chute 13 moves to the maximum stroke position outside the baffle wall 16, the liquid inlet chute 13 leaves the top of the base platform 1. The liquid inlet chute 13 only extends into the top of the base platform 1 when waste residue enters the base platform 1, and is in a detached state when not in use to avoid the liquid inlet chute 13 interfering with the discharge mechanism 4. Unless otherwise described, the fixing method is welded or threaded using common technical means in the industry.

[0039] like Figure 13 As shown in Example 1: The slag pit treatment system of the electric arc furnace is provided with one set, and two sets of second tracks are provided on both sides of the slag pit treatment system; the slag hopper 15 is moved and transported along the second track by a slag transport vehicle; the water tank 17 of the slag pit treatment system is connected to the second water pump 7 through pipeline for external discharge.
