[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-4 As shown, this embodiment provides a mobile vertical reduction furnace dust suppression and slag removal system, including a vertical reduction tank 1, a central pipe 2, a material ball 3, a crystallizer 4, a cooling water jacket 5, and a sealing cover 6. The material ball 3 is placed in the space between the reduction tank 1 and the central pipe 2. Magnesium vapor flows downward through the holes on the central pipe 2 to crystallize on the crystallizer 4. A guide rail is provided above the reduction tank 1, and a dust suppression component is slidably connected to the guide rail. The dust suppression component is detachably connected to the reduction tank 1. A slag removal component is provided below the reduction tank 1, and the slag removal component is transferred by a lifting trolley.

[0023] By installing guide rails above the reduction tank 1, the dust suppression component can slide on the guide rails and be detachably connected to the reduction tank 1. A slag discharge component is installed below the reduction tank 1 and moved via a lifting trolley. This achieves flexible movement of the dust suppression component and convenient transfer of the slag discharge component, providing convenience for dust suppression and slag discharge operations in the magnesium smelting process and improving the operational flexibility and adaptability of the entire system. This invention prevents dust from directly floating in the air by installing dust suppression components, suppressing dust dispersion and preventing backflow and fire from the furnace top. The dust suppression component is quickly moved to the corresponding opening of the reduction tank 1 via the guide rails, and slag discharge can be completed simply by lifting the central pipe 2, greatly improving efficiency. The slag discharge component reduces manual operation effort and improves efficiency.

[0024] The dust suppression system is further optimized by including a dust cover 9, which is adapted to the top of the reduction tank 1. A central inlet 8 is located on the top of the dust cover 9, and this central inlet 8 is adapted to a central pipe 2. A dust removal port 11 is located on the side wall of the dust cover 9, and the dust removal port 11 is detachably connected to external dust removal equipment. The dust cover 9, adapted to the top of the reduction tank 1, effectively covers the top of the tank, preventing dust overflow. The central inlet 8, adapted to the central pipe 2, ensures a tight connection between the central pipe 2 and the dust cover 9, without affecting the normal flow of magnesium vapor. The dust removal port 11 on the side wall, detachably connected to external dust removal equipment, facilitates the timely removal of generated dust, maintains internal system cleanliness, and reduces the impact of dust on the magnesium smelting process.

[0025] Furthermore, the difference between the inner diameter of the dust cover 9 and the outer diameter of the reduction tank 1 is no more than 5mm; the difference between the inner diameter of the central pipe 8 and the outer diameter of the central pipe 2 is no more than 5mm.

[0026] To further optimize the design, a dust collector flange 10 is installed at dust collector port 11, which connects to external dust collection equipment. A manual butterfly valve 12 is installed on dust collector port 11. The dust collector flange 10 facilitates connection to external dust collection equipment and ensures the stability and sealing of the connection. The manual butterfly valve 12 allows for control of the opening and closing of dust collector port 11 as needed, flexibly adjusting the dust collection process and improving the system's controllability.

[0027] The design was further optimized by installing a positioning support 20 above the reduction tank 1, on which the dust cover 9 is fixedly mounted. This positioning support 20 above the reduction tank 1, with the dust cover 9 fixedly mounted, provides stable support for the dust cover 9, ensuring its position remains fixed during the magnesium smelting process and improving the system's stability and reliability.

[0028] In a further optimized design, rollers 21 are installed at the four corners of the bottom surface of the support 20, and the rollers 21 are adapted to the guide rail. The installation of rollers 21 at the four corners of the bottom surface of the support 20 and the adaptation of rollers 21 to the guide rail allow the support 20 to move flexibly along the guide rail, thereby driving the dust cover 9 to move, further enhancing the mobility of the dust suppression component and facilitating the adjustment of the position of the dust cover 9 according to actual needs.

[0029] The design is further optimized so that the slag discharge assembly includes a slag storage tank 16, with a slag storage tank opening flange 15 installed on the top of the slag storage tank 16, and a slag outlet 14 at the bottom of the reduction tank 1. The slag outlet 14 is detachably connected to the slag storage tank opening flange 15 via a connecting flange 13. This connection method facilitates the installation and disassembly of the slag storage tank 16, makes it easier to discharge the slag inside the slag storage tank 16, and improves the convenience of the slag discharge operation.

[0030] Furthermore, the diameter difference between the opening of the slag storage tank 16 and the slag outlet 14 is no more than 5 mm.

[0031] The design was further optimized so that the inner layer of the slag storage tank 16 is made of castable refractory 17, and the outer layer is made of heat-resistant steel 18. The inner layer of the slag storage tank 16, made of castable refractory 17, has excellent high-temperature resistance and corrosion resistance, effectively protecting the inner wall of the slag storage tank 16 and extending its service life. The outer layer, made of heat-resistant steel 18, increases the overall strength and stability of the slag storage tank 16, protecting it from deformation during long-term contact with high-temperature slag 7, thus increasing its service life.

[0032] To further optimize the design, symmetrical forklift tilting holes 19 are provided on the slag storage tank 16. The symmetrical tilting forklift tilting holes 19 on the slag storage tank 16 facilitate the use of a forklift to tilt the slag storage tank 16, making it easier to completely empty the slag inside the slag storage tank 16, improving the efficiency and thoroughness of slag removal, and also facilitating the handling and transfer of the slag storage tank 16.

[0033] Working Principle: After magnesium smelting in the vertical reduction furnace, the dust suppression component is moved above reduction tank 1 via a track, with the central pipe port 8 aligned with the central pipe 2. The dust cover 9 then descends to cover reduction tank 1. The slag storage tank 16 is transported to below the slag outlet 14 via a movable lifting trolley, and the connecting flange 13 is connected to the slag storage tank port flange 15 using bolts. The bag filter dust collector is connected via the dust collection port flange 10. The manual butterfly valve 12 is opened, and the central pipe 2 is lifted through the central pipe port 8 using a lifting device. The slag 7 then slides down the inner wall of reduction tank 1 into the slag storage tank 16. The dust raised by the falling slag 7 rises through reduction tank 1 into the dust cover 9, and is collected by a duct fan through the dust collection port 11. Once all the slag 7 has fallen into the slag storage tank 16, a forklift transports it to a designated location for centralized processing via the tilting forklift hole 19. After completing the slag discharge task for one reduction tank 1, the dust suppression component moves to the next reduction tank 1 via a guide rail to begin the next cycle. The dust suppression component is positioned by the support 20 and moves on the slide rail driven by the roller 21.

[0034] It has the following beneficial effects: The dust cover 9 fits tightly to the diameter of the reduction tank 1, and the dust is drawn from the dust collection port 11 and sent into the bag filter by the duct fan, preventing dust from floating directly in the air, suppressing dust dispersion, and preventing backflow of smoke and fire from the furnace top. The movable dust suppression components quickly reach the corresponding reduction tank 1 opening, and slag discharge can be completed simply by lifting the central pipe 2, greatly improving efficiency. The slag storage car, in conjunction with the liftable mobile trolley, quickly connects to the corresponding reduction tank 1 via flange pairing to complete slag discharge. This reduces manual operation and improves efficiency.
