Description

Technical Field

[0001] This utility model relates to the field of refractory castable production technology, and more specifically, to a mixing machine for processing refractory castables. Background Technology

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580°C. They are now defined as any material whose physical and chemical properties allow it to be used in a high-temperature environment. Refractory material mixing machines are used to stir and mix several different types and particle sizes of materials to achieve a uniform mixing effect.

[0003] After deceleration, it was discovered that the application with application number CN202422567759.X, entitled "A Mixing Machine for Refractory Castable Production," referenced Chinese Patent Publication No. CN219984427U. This application addressed a problem with a mixing machine for refractory castable production, where mixing primarily relied on a mixing rod with a fixed position and height. This constant stirring at the same angle and height easily led to uneven mixing, negatively impacting the speed and quality of refractory castable mixing. The application then addressed this issue by... The first motor, main shaft, adjusting groove, sleeve, and movable block enable the first material rod, second material rod, and support rod to stir and mix the material in the mixing cylinder. During mixing, the distance between the first and second material rods is adjusted via the first hydraulic cylinder, slider, fixed ring, limiting groove, and adjusting groove. The first and second material rods mix materials at different heights. When adjusting the height of the first and second material rods, the movable block changes the tilt angle of the support rod, allowing the support rod to mix the material at different angles. The height adjustment of the second feed rod and the adjustment of the support rod angle allow for mixing of materials at different angles and heights, applying different shear forces to the materials, resulting in rapid and uniform mixing, effectively improving the quality and efficiency of mixing. Simultaneously, the second motor and rotating shaft drive the impact rod, crushing blade, and distribution plate to rotate. The impact rod and crushing blade break up lumps in the material, while the distribution plate disperses the material into the mixing cylinder, facilitating mixing and effectively improving the speed and quality of mixing. However, in actual use, the linkage angle adjustment mechanism of this application is relatively complex, and it requires a telescopic baffle to seal the gaps. During the mixing rotation, the telescopic baffle is in prolonged frictional contact with the refractory castable, enduring impact and wear, making it prone to damage, resulting in poor stability and reduced service life. Furthermore, during crushing, the material falls vertically at high speed, making it difficult for the crushing blade to completely crush larger particles, resulting in some non-compliant material still participating in the mixing process, affecting the yield rate. Further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] Furthermore, a top cylinder is fixedly installed on the bottom surface of the lifting frame, and a bottom hole is opened on the bottom surface of the top cylinder. A roller is rotatably connected to the surface of the central shaft tube, and the roller rolls against the bottom surface of the top cylinder. A material feeding frame is fixedly installed on the other side surface of the central shaft tube, and a material feeding rod is fixedly installed on the bottom surface of the material feeding frame, and the bottom surface of the material feeding rod abuts against the bottom surface of the top cylinder.

[0008] Furthermore, a feeding hopper is connected through the top surface of the lifting frame, and the lifting frame is rotatably connected to the central shaft tube through a limit bearing.

[0009] Furthermore, the central shaft tube is rotatably connected to the top cylinder via a limit bearing, and the central shaft tube, lifting frame, mixing tank, and top cylinder are arranged coaxially.

[0010] Furthermore, a guide rod is fixedly installed on the top surface of the lifting frame, and the guide rod passes through the gantry and is slidably connected to the gantry.

[0011] Furthermore, the connecting shaft extends through the surface of the central tube, and multiple sets of connecting shafts and agitator plates are arranged from top to bottom.

[0012] Furthermore, the bottom surface of the mixing tank is connected to a discharge port, and a bottom cover is spirally sleeved on the bottom surface of the discharge port.

[0013] Furthermore, the brake motor is electrically connected to an external power source via an electric slip ring.

[0014] Compared with the prior art, the present invention provides a mixing mill for processing refractory castables, which has the following beneficial effects: (1) This utility model adopts an adjusting rod and a stirring plate. When stirring, the drive motor drives the drive gear to rotate, drives the central shaft tube to rotate, and drives the stirring plate to rotate, so as to mix the refractory castable inside the mixing tank. The electric cylinder drives the lifting frame to rise and fall, and drives the stirring plate to rise and fall, changing the mixing position. At the same time, the brake motor drives the adjusting rod to rotate, drives the first bevel gear to rotate, drives the second bevel gear to rotate, drives the connecting shaft to rotate, drives the stirring plate to flip the angle, and adjusts the mixing angle, thereby improving the mixing efficiency of the refractory castable. The connecting shaft is sealed to the central shaft tube through a sealed bearing, which prevents the refractory castable from entering the central shaft tube. The sealing performance is good.

[0015] (2) This utility model adopts a top cylinder and a bottom hole. When mixing, the refractory castable is fed into the top cylinder from the feeding hopper. When the central shaft rotates, it drives the grinding roller to rotate and crush the refractory castable. The refractory castable that does not meet the particle size requirements is crushed to meet the particle size requirements and then discharged into the mixing tank through the bottom hole. This avoids the refractory castable that does not meet the particle size requirements from participating in the mixing process and improves the yield. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a mixing machine for processing refractory castables is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the mixing machine for processing refractory castables according to an embodiment of the present invention includes a mixing tank 1 and a lifting frame 10. A gantry 11 is fixedly installed on the top of the mixing tank 1, and an electric cylinder 12 is fixedly installed on the top surface of the gantry 11. The lifting frame 10 is fixedly installed on the bottom surface of the moving rod of the electric cylinder 12. A central shaft tube 2 is rotatably connected through the center of the lifting frame 10, and a brake motor 4 is fixedly installed on the top surface of the central shaft tube 2 to facilitate the rotation and positioning of the adjusting rod 3. An adjusting rod 3 is installed at the output end of the brake motor 4. The bottom surface of the adjusting rod 3 is rotatably connected to the inner bottom surface of the central shaft tube 2 via a rotating connecting seat 9. A first bevel gear 21 is fixedly mounted on the surface of the adjusting rod 3, and a connecting shaft 20 is rotatably connected to the surface of the central shaft tube 2 via a sealed bearing 22. An agitator plate 8 is fixedly mounted on one end of the connecting shaft 20, and a second bevel gear 23 is fixedly connected to the other end of the connecting shaft 20. The second bevel gear 23 meshes with the first bevel gear 21, which is a common drive connection method.

A drive gear 6 is installed at the output end of motor 5, and a driven gear 7 is fixedly sleeved on the surface of the central shaft tube 2, with the driven gear 7 meshing with the drive gear 6. This is a common stirring structure. During stirring, the drive motor 5 drives the drive gear 6 to rotate, which in turn drives the central shaft tube 2 to rotate, and the stirring plate 8 to rotate, thus mixing the refractory castable inside the mixing tank 1. The electric cylinder 12 drives the lifting frame 10 to rise and fall, which in turn drives the stirring plate 8 to rise and fall, changing the stirring and mixing position. At the same time, the brake motor 4 drives the adjusting rod 3 to rotate, which in turn drives the first bevel gear 21 to rotate, the second bevel gear 23 to rotate, and the connecting shaft 20 to rotate, causing the stirring plate 8 to rotate at an angle to adjust the mixing angle, thereby improving the mixing efficiency of the refractory castable. The connecting shaft 20 is sealed to the central shaft tube 2 through a sealed bearing 22, which prevents the refractory castable from entering the central shaft tube 2, ensuring good sealing. At the same time, the sealed bearing 22 avoids direct impact with the refractory castable during rotation, resulting in a longer service life, better stability, and a simpler structure, making it more convenient to use.

[0022] In one embodiment, a top cylinder 15 is fixedly installed on the bottom surface of the lifting frame 10, and a bottom hole 18 is opened on the bottom surface of the top cylinder 15. A grinding roller 16 is rotatably connected to the surface of the central shaft tube 2, and the grinding roller 16 rolls against the inner bottom surface of the top cylinder 15. A material feeding frame 17 is fixedly installed on the other side surface of the central shaft tube 2, and a material feeding rod is fixedly installed on the bottom surface of the material feeding frame 17, and the bottom surface of the material feeding rod abuts against the inner bottom surface of the top cylinder 15. The material feeding rod facilitates the feeding of raw materials, facilitates the crushing of raw materials, and facilitates the passage of raw materials through the bottom hole 18. During the mixing process, refractory castable is fed into the top cylinder 15 from the feeding hopper 14. When the central shaft tube 2 rotates, it drives the grinding roller 16 to rotate, crushing the refractory castable. Refractory castable that does not meet the particle size requirements is crushed to the required particle size and then discharged into the mixing tank 1 through the bottom hole 18, which avoids refractory castable that does not meet the particle size requirements from participating in the mixing process and improves the yield.

[0023] In one embodiment, the top surface of the lifting frame 10 is connected to the feeding hopper 14, and the lifting frame 10 is rotatably connected to the central shaft tube 2 through the limit bearing, thereby improving the stability of the rotation of the central shaft tube 2.

[0024] In one embodiment, the central shaft tube 2 is rotatably connected to the top cylinder 15 via a limiting bearing, and the central shaft tube 2, the lifting frame 10, the mixing tank 1, and the top cylinder 15 are arranged coaxially to improve the stability of the rotation of the stirring plate 8.

[0025] In one embodiment, a guide rod 13 is fixedly installed on the top surface of the lifting frame 10, and the guide rod 13 passes through the gantry 11 and is slidably connected to the gantry 11, thereby improving the stability of the lifting frame 10 in raising and lowering.

[0026] In one embodiment, the connecting shaft 20 extends through the surface of the central tube 2, and multiple sets of the connecting shaft 20 and the stirring plate 8 are arranged from top to bottom to improve the mixing range and efficiency.

[0027] In one embodiment, the bottom surface of the mixing tank 1 is connected to a discharge port 19, and the bottom surface of the discharge port 19 is spirally fitted with a bottom cover for easy discharge.

[0028] In one embodiment, the brake motor 4 is electrically connected to an external power source via an electric slip ring, which facilitates rotation and power supply. This is a common power supply method and is not shown in detail in the figure.

[0029] Working principle: During mixing, the drive motor 5 drives the drive gear 6 to rotate, which in turn drives the central shaft tube 2 and the agitator plate 8 to rotate, mixing the refractory castable inside the mixing tank 1. The electric cylinder 12 drives the lifting frame 10 to rise and fall, which in turn drives the agitator plate 8 to rise and fall, changing the mixing position. At the same time, the brake motor 4 drives the adjusting rod 3 to rotate, which in turn drives the first bevel gear 21 to rotate, the second bevel gear 23 to rotate, and the connecting shaft 20 to rotate, causing the agitator plate 8 to rotate at an angle to adjust the mixing angle, thereby improving the mixing efficiency of the refractory castable. The connecting shaft 20 is sealed to the central shaft tube 2 through a sealed bearing 22 to prevent the refractory from being exposed to air. The refractory castable enters the central shaft tube 2, ensuring good sealing. Simultaneously, the sealed bearing 22 avoids direct impact with the refractory castable during rotation, resulting in a longer service life, better stability, and a simpler structure, making it more convenient to use. During mixing, the refractory castable is fed from the feeding hopper 14 into the top cylinder 15. As the central shaft tube 2 rotates, it drives the grinding roller 16 to rotate, crushing the refractory castable. Refractory castable that does not meet the particle size requirements is crushed to the required size and then discharged into the mixing tank 1 through the bottom hole 18. This prevents refractory castable that does not meet the particle size requirements from participating in the mixing process, improving the yield rate.
