Description

Technical Field

[0001] This utility model relates to the field of refractory mixing technology, specifically to a refractory mixing device for molten iron ladle anti-slag sticking. Background Technology

[0002] The iron ladle anti-slag sticking castable mixing device is a piece of equipment used for mixing iron ladle anti-slag sticking castables. It belongs to the field of castable mixing technology. Its core function is to achieve uniform mixing and precise discharge of the castable through a specific structural design, thereby improving the preparation quality of the iron ladle anti-slag sticking castable. For example: The mixing equipment for molten iron ladle castings described in application number CN202320673468.1 innovatively integrates the traditional horizontal mixing and vertical oscillating mixing modes, significantly improving the mixing efficiency of the castings through the dynamic composite mixing principle; its internal multi-layer directional water injection structure, with the help of the three-dimensional dispersion effect during the mixing process, effectively solves the problem of clumping caused by traditional single-point water injection.

[0003] However, the equipment has a key design flaw: due to the lack of a quantitative discharge control system, it is difficult to accurately match the mold volume requirements in actual production, often resulting in problems such as overflow of casting material or insufficient filling in certain areas. This not only causes material waste, but may also affect the consistency of the anti-slag sticking performance of the molten iron ladle due to uneven filling. It needs to be improved by adding a mechanical quantitative mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a stirring device for anti-sticking slag casting material in molten iron ladles, so as to solve the problem that the existing patents on the market mentioned in the background art do not have a uniform discharge structure, and in actual use, the flow rate between the mold and the equipment cannot be accurately controlled, resulting in overflow or even partial cavity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for anti-sticking slag castable in molten iron ladles, comprising a mixing chamber, a first support frame, a first mixing paddle, a second support frame, and a first gear; A quantitative discharge mechanism is provided below the mixing chamber. The quantitative discharge mechanism includes a discharge pipe, a valve partition, a second lead screw, a second motor, and an auger. The auger is rotatably connected to the discharge pipe, the valve partition is slidably connected to the top of the discharge pipe, the valve partition is threadedly connected to the side of the second lead screw, and the second lead screw is fixedly connected to the output end of the second motor.

[0006] As a preferred technical solution of this utility model, the side of the mixing chamber is fixedly connected to a second support frame. There are two second support frames symmetrically distributed, and the first support frame is fixedly connected to the opposite position of the second support frame. The first support frame is a rectangular frame structure, and a guide rail groove is opened below the first support frame. Using the above technical solution, two symmetrically distributed second support frames are fixedly connected to the side of the mixing chamber, and a first support frame with a rectangular frame structure is fixedly connected to the opposite position. A guide rail groove is opened below the first support frame. This structure forms a stable support system with the symmetrically distributed second support frames and the first support frame, which can evenly bear the weight of the mixing chamber and the force generated during mixing. At the same time, the guide rail groove provides precise guidance for the movement of the subsequent linkage mechanism, ensuring that the lifting process of the mixing chamber is smooth and does not deviate.

[0007] As a preferred technical solution of this utility model, the lower part of the first support frame is rotatably connected to one end of the second connecting rod, the lower part of the second support frame is rotatably connected to one end of the first connecting rod, the second connecting rod and the first connecting rod rotate in a cross manner, and the other end of the second connecting rod is rotatably connected to the bearing plate.

At the same time, with the guiding and limiting functions of the guide rail frame and the guide rod, precise control of the lifting of the mixing chamber is achieved, avoiding deviation or shaking during the movement, so as to adapt to molds of different heights to complete the pouring operation.

[0009] As a preferred technical solution of this utility model, a first motor is fixedly connected to the side of the mixing chamber, the output shaft of the first motor is fixedly connected to one end of the second mixing blade, and a first gear is fixedly connected to the other end of the second mixing blade.

The discharge pipe, which is connected to the center line of the mixing chamber, is slidably connected to the mixing chamber with a valve partition. The side of the valve partition is threaded with a second screw and fixed to the output shaft of the second motor. This linkage design enables the first and second mixing blades to achieve bidirectional mixing through the gear transmission system, eliminating mixing dead zones and ensuring uniform mixing of the casting material. At the same time, it drives the auger to run in preparation for discharge. The valve partition can precisely control the discharge amount through the second motor and the second screw to meet different production needs.

Four first support legs arranged in a rectangular pattern are fixed on the side of the mixing chamber. This layout can evenly distribute the weight of the mixing chamber and enhance the overall stability of the equipment.

[0013] 2. Regarding the design of the lifting mechanism of the mixing silo, the first support frame and the second connecting rod, as well as the second support frame and the first connecting rod, are rotatably connected. The two connecting rods rotate in opposite directions, and their other ends are rotatably connected to the bearing plate, forming a "scissor fork" type lifting structure. This ensures that the bearing plate remains stable during lifting and lowering, allowing for flexible lifting and lowering of the mixing silo and even weight distribution. The other end of the first connecting rod is slidably connected to the guide rail frame. The drive rod is clamped between the first connecting rods and is slidably and threadedly connected to the guide rod. It is fixed to the side with the third motor. The third motor drives the first lead screw to rotate, and the rotational motion is converted into linear motion through threaded transmission. Combined with the guide rail frame and the guide rod's guide limit, precise control of the lifting and lowering of the mixing silo is achieved. 3. In the linkage transmission between mixing and discharging, the first motor drives the double mixing blades and auger through gear transmission. The valve baffle at the discharge pipe is controlled by the second screw and the second motor. This linkage design enables the first and second mixing blades to mix in both directions through gear transmission, eliminating mixing dead zones and ensuring uniform mixing of the casting material. At the same time, it drives the auger to operate to prepare for discharge. The valve baffle can precisely control the discharge amount through the second motor and the second screw. The overall structure is simple and easy to maintain. 4. Regarding the adaptability of equipment height, the second support leg fixed on the side of the mixing chamber has bolt holes on its surface, and a telescopic sleeve is slidably connected below and fixed with bolts. This design allows for adjustment of the relative position of the telescopic sleeve and the second support leg, enabling flexible adjustment of the equipment height to meet different working environments and production needs, and improving the adaptability of the equipment.

[0018] The quantitative discharge mechanism installed below the mixing chamber 1 consists of a discharge pipe 17, a valve baffle 20, a second lead screw 21, a second motor 22, and an auger 19. The auger 19 is rotatably connected to the discharge pipe 17, and the valve baffle 20 is slidably connected above the discharge pipe 17 and threadedly connected to the second lead screw 21. The second lead screw 21 is driven by the second motor 22. This mechanism drives the second lead screw 21 to rotate through the second motor 22, which drives the valve baffle 20 to slide to control the opening and closing of the discharge port. At the same time, the auger 19 rotates to push the casting material, achieving precise quantitative discharge, avoiding material waste, ensuring that the discharge amount meets production needs, and improving operational professionalism. Two symmetrically distributed second support frames 4 are fixed on the side of the mixing chamber 1, and a first support frame 2 with a rectangular frame structure is set at the opposite position. A guide rail groove is opened below the first support frame 2. The symmetrically distributed second support frames 4 and the first support frame 2 form a stable support system, which can evenly bear the weight of the mixing chamber 1 and the force generated during the mixing process, and prevent the equipment from shaking. The guide rail groove of the first support frame 2 provides precise guidance for the movement of the subsequent linkage mechanism, ensuring that the mixing chamber 1 moves smoothly along a fixed trajectory during the lifting process, avoiding deviation, and ensuring the stability and reliability of the equipment operation. The first support frame 2 is rotatably connected to the second connecting rod 10 below, and the second support frame 4 is rotatably connected to the first connecting rod 9 below. The two connecting rods rotate in a cross manner, and their other ends are rotatably connected to the bearing plate 11.

The drive rod 13 is clamped between the first connecting rods 9 and is slidably and threadedly connected to the guide rod 14. It is driven by the third motor 26. This "scissor fork" type connecting rod structure drives the first lead screw 15 to rotate through the third motor 26. The rotational motion is converted into linear motion by the threaded transmission, which drives the connecting rod mechanism to lift and lower the bearing plate 11. The guiding and limiting function of the guide rail frame 12 and the guide rod 14 ensures that the lifting process is smooth and without shaking, making the lifting operation of the mixing chamber 1 flexible and controllable. At the same time, it evenly distributes the weight and improves the load-bearing strength and motion accuracy of the mechanism. The first motor 16 on the side of the mixing chamber 1 drives the second mixing paddle 18 to rotate. The second mixing paddle 18 drives the first mixing paddle 3 through the meshing of the first gear 5 and the second gear 6. The second gear 6 drives the auger 19 to rotate through the third gear 7 and the fourth gear 8. The valve baffle 20 at the connection between the discharge pipe 17 and the mixing chamber 1 is controlled by the second screw 21 and the second motor 22. The gear transmission system realizes bidirectional mixing of the two mixing paddles, eliminates the dead zone of mixing, and ensures that the castable is mixed evenly. At the same time, the auger 19 operates synchronously to provide power for the discharge. The valve baffle 20 precisely controls the discharge amount through the cooperation of the second motor 22 and the second screw 21 to meet the quantitative requirements of different production scenarios. Combined with symmetrical support and adjustable lifting structure, it enhances the professionalism and adaptability of the equipment in the mixing of anti-sticking slag castable in molten iron ladles.
