Description
Technical Field

[0002] In the steelmaking industry, the production process of protective slag is crucial, and its uniformity and quality directly affect the protective effect of molten steel and the subsequent smelting quality.
[0003] As one of the core equipment for mold slag production, the performance and efficiency of the mixer directly affect the overall operation of the production line. However, traditional mold slag mixers for steelmaking mostly use a single mixing method when processing raw materials, and often lack an effective initial crushing mechanism for larger or blocky raw materials, resulting in low mixing efficiency and high energy consumption.
[0004] Most common mixers are fixed structures. Their design often focuses on the realization of the mixing function, but ignores the pretreatment step of the raw materials before entering the mixing box, that is, the crushing and refinement of the raw materials. This design has certain limitations in practical applications, especially for batches containing larger particles or blocky raw materials. The mixing effect is not ideal, and it is easy to cause equipment failure or blockage, increasing the instability of the production process. Utility Model Content

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" 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 direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0027] Please refer to Figures 1 - 3 , a mixer for producing protective slag for steelmaking, including a mixing box body 1, a protective box body 2, an adjusting and crushing component, and a linkage mixing component. The protective box body 2 is arranged on the top of the mixing box body 1. A motor 3 is arranged inside the protective box body 2. The output end of the motor 3 is provided with an adjusting and crushing component. The inside of the mixing box body 1 and the inside of the protective box body 2 are jointly provided with a linkage mixing component;
[0028] Embodiment 1: The adjusting and crushing component includes a first gear 5, a telescopic rod 6, a clamping plate 7, a rotating wheel 8, and a crushing rod 9. The output end of the motor 3 is bolted and fixed with a first rotating rod 4. The first gear 5 is bolted and fixed at the end of the first rotating rod 4. The telescopic rod 6 is installed inside the first gear 5. The end of the movable end of the telescopic rod 6 is bolted and fixed with the clamping plate 7. The clamping plate 7 is clamped outside the rotating wheel 8. The crushing rod 9 is bolted and fixed to the middle of the rotating wheel 8;
[0029] In this embodiment, a ring-shaped retraction groove is formed in the middle of the bottom of the first gear 5. After the first rotating rod 4 and the first gear 5 are inserted into the ring-shaped retraction groove, the upper and lower ends of the insertion part of the first rotating rod 4 and the first gear 5 are fixed by screws.
[0030] It should be noted that the design of the ring-shaped retraction groove not only provides a stable insertion structure for the first rotating rod 4 and the first gear 5, but also ensures the tight connection between the two through the fixation of screws, preventing loosening or deviation during high-speed rotation, thus ensuring the stability and reliability of power transmission.
[0031] In this embodiment, there are two telescopic rods 6, and they are installed upside down inside the ring-shaped retraction groove near the two side walls. The movable end of the telescopic rod 6 passes through the ring-shaped retraction groove and is bolted and fixed to the top of the clamping plate 7. The top of the clamping plate 7 can be inserted into the ring-shaped retraction groove.
[0032] It should be noted that the double setting of the telescopic rod 6 enhances the stability and reliability of the connection between the clamping plate 7 and the rotating wheel 8. The upside-down installation method enables the telescopic rod 6 to more effectively control the up and down movement of the clamping plate 7, thereby accurately realizing the linkage or separation from the rotating wheel 8.
[0033] In this embodiment, an insertion block is provided at the bottom of the clamping plate 7, and it is inserted into the insertion hole provided at the top of the rotating wheel 8 through the insertion block. A ring-shaped baffle 10 is provided in the middle of the interior of the stirring box body 1. Blades are provided on the outside of the crushing rod 9, and the crushing rod 9 is installed inside the ring-shaped baffle 10. At the top of the stirring box body 1 and on the front and rear sides of the ring-shaped baffle 10, a top feed port 11 is provided.
[0034] It should be noted that the design of the insertion block and the insertion hole makes the connection between the clamping plate 7 and the rotating wheel 8 more firm, and a stable linkage relationship can be maintained even during the high-strength crushing process. The ring-shaped baffle 10 not only provides an installation platform for the crushing rod 9 and its blades, but also plays a role of isolation and protection, preventing the raw materials from splashing out of the stirring box body 1 during the crushing process. The setting of the top feed port 11 facilitates the addition of raw materials, and its position design also takes into account the cooperation with the ring-shaped baffle 10 to ensure that the raw materials can smoothly enter the crushing area.
[0035] Embodiment Two: The linkage stirring assembly includes two second gears 13 and two second stirring rods 14. The outer parts of the two second stirring rods 14 are respectively bolt-fixed to the middle parts of the two second gears 13. The outer parts of the two second gears 13 are both meshed with the first gear 5. A plurality of groups of stirring blades 15 are bolt-fixed on the outer parts of the two second stirring rods 14 inside the stirring box body 1.
[0036] In this embodiment, the tops of the two second stirring rods 14 are rotationally connected to the protective box body 2 through bearings, and the plurality of groups of stirring blades 15 bolt-fixed on the outer parts of the two second stirring rods 14 are staggered with each other.
[0037] In this embodiment, the bottom surface of the inner wall of the stirring box body 1 slopes towards the middle. An electric valve is provided in the middle of the bottom of the stirring box body 1. A side feed port 12 is provided in the middle of the outside of the stirring box body 1, and a support seat 16 is provided at the bottom.
[0038] Beneficial effects:
[0039] For the mixer used in the production of protective slag for steelmaking, the first gear 5 driven by the motor 3 not only directly transmits power to the linkage stirring assembly to achieve efficient stirring inside the stirring box body 1, but also controls the linkage between the clamping plate 7 and the rotating wheel 8 through the telescopic rod 6 to realize the preliminary crushing function of large-particle raw materials. When crushing is required, the telescopic rod 6 extends, the clamping plate 7 clamps the rotating wheel 8, driving the crushing rod 9 and the blades thereon to rotate, effectively crushing large-particle raw materials. When no crushing is needed, the telescopic rod 6 shortens, reducing energy consumption and wear. At the same time, the meshing design of the two second gears 13 and the first gear 5 enables the two second stirring rods 14 and the stirring blades 15 thereon to rotate synchronously, forming a multi-dimensional stirring effect to ensure uniform mixing of the raw materials.
