Description

Technical Field

[0001] This utility model relates to the technical field of corundum spinel aggregate processing equipment, specifically a mixing device for processing corundum spinel aggregate. Background Technology

[0002] Corundum-spinel aggregate is a high-performance refractory material with corundum (α-Al₂O₃) and spinel (MgAl₂O₄) as its main components. It possesses a high melting point (>2000℃), high strength, corrosion resistance, and excellent thermal shock stability, and is widely used in the metallurgical, cement kiln, and chemical industries. During its processing, different formulations require the mixing of raw materials with different particle sizes and proportions (such as corundum particles, spinel powder, binders, etc.), and the density of the raw materials varies greatly (corundum 3.95 g / cm³). 3 vs. spinel 3.6g / cm 3 Furthermore, its high hardness (Mohs hardness ≥ 8) can easily lead to uneven mixing or equipment wear.

[0003] Traditional manual or static mixing equipment is difficult to meet the requirements of uniformity and batch stability of corundum spinel aggregate. Uneven mixing can lead to local stress concentration, cracks or performance degradation in the sintered material. For example, uneven distribution of spinel may reduce thermal shock resistance, while binder agglomeration will affect molding strength. Mixing equipment can break up particle agglomeration through forced shearing and convection, and adapt to the differences in physical properties of different formulations.

[0004] Current mixing equipment mostly uses fixed-angle stirring rollers, which cannot be dynamically adjusted according to the characteristics of the raw materials. If the inclination angle of the stirring roller is too large, the airflow disturbance is enhanced during high-speed rotation, and fine powder (such as spinel powder) is easily thrown to the top of the equipment, forming dust accumulation, while coarse particles (corundum aggregate) sink due to gravity, resulting in stratification. Furthermore, the fixed angle cannot dynamically adjust the balance between shear force and convection intensity. For example, when high shear is required to break up spinel powder agglomerates, the fixed inclination angle may weaken the shearing effect due to the dominance of axial flow; when strong convection is required to prevent corundum settling, the fixed inclination angle may not be able to effectively turn over the bottom particles due to insufficient radial movement, failing to meet the mixing requirements of multiple raw materials. Therefore, a mixing device for corundum spinel aggregate processing is proposed to solve the above problems. Utility Model Content

[0028] 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.

[0029] Example 1:

[0030] Please see Figure 1-5 A mixing device for processing corundum spinel aggregate includes a protective shell 1. The protective shell 1 has a first support frame 11 and a second support frame 12 on its exterior for support, and a mixing chamber 16 for holding the raw materials to be mixed inside. The tops of the first support frame 11 and the second support frame 12 are spaced apart to form a transmission area. The first support frame 11 has a section 111 extending into the interior of the protective shell 1, and a ball socket is formed on 111. The ball socket is rotatably connected to a mixing component 3 for mixing the raw materials. The mounting platform of the second support frame 12 has a linkage component 2 for linkage and a drive motor 14 for driving. The output end of the drive motor 14 is connected to a drive gear 15, which is connected to the linkage component 2. The linkage component 2 is connected to the mixing component 3. The linkage assembly 2 includes an electric push rod 21 fixedly mounted on the top of the second support frame 12. The push rod end of the electric push rod 21 is rotatably connected to a linkage shaft 22. A driven gear 23 is provided on the rod body of the linkage shaft 22. The driven gear 23 is rotatably mounted on the first support frame 11 and is engaged with the transmission gear 15. A limit groove 24 is formed on the driven gear 23. A limit block 25 is provided on the linkage shaft 22 and slidably connected in the limit groove 24. A limit ring 26 is also provided on the linkage shaft 22.

[0031] The stirring assembly 3 includes a linkage gear 31 positioned below the limiting ring 26 and a mounting ring 32 fixedly mounted on the linkage shaft 22. The linkage gear 31 has a hole in its center for the linkage shaft 22 to pass through, but the inner wall of the hole does not contact the linkage shaft 22. A transmission arm 33 is inclinedly mounted on the mounting ring 32, and a connecting ring 34 is located at the other end of the transmission arm 33. A stirring rod 35 is located inside the connecting ring 34, and the stirring rod 35 is inclinedly positioned within the stirring chamber 16 along the axis of the protective shell 1. At least two adjusting gears 36 are located at the top of the stirring rod 35, one of which meshes with the linkage gear 31. A ball head 37 is located in the middle of the stirring rod 35, and the stirring rod 35 is rotatably connected to a ball socket via the ball head 37. A stirring blade 38 for stirring the raw materials is located at the bottom of the stirring rod 35. At least two telescopic rods 311 are located at the top of the linkage gear 31, and the telescopic ends of the two telescopic rods 311 are fixedly connected to the first support frame 11 to limit the linkage gear 31 horizontally.

[0032] In this embodiment, a mixing device for processing corundum spinel aggregate is provided. The electric push rod 21 is in a retracted state, the stirring rod 35 is suspended in the stirring chamber 16, the drive motor 14 is on standby, and the stirring blade 38 is stationary.

[0033] Subsequently, the workers can add corundum and spinel aggregates into the mixing chamber 16 of the protective shell 1 in proportion. Then, by starting the drive motor 14, the power is transmitted sequentially through the drive gear 15, driven gear 23, linkage shaft 22, and drive arm 33. During the rotation of the drive arm 33, it can drive the stirring rod 35 to rotate around the ball head 37. At this time, when the stirring rod 35 rotates, the bottom 38 can also rotate to achieve the mixing of raw materials. At the same time, when 35 is rotating, the top 36, which meshes with 31, can rotate, thereby driving 35 and 38 to achieve the effect of rotation, thus ensuring the mixing effect of raw materials. At this time, the rotation angle of the stirring rod 35 is α1, and the rotation diameter of the stirring blade 38 around the ball head 37 is L1.

[0034] In Example 2, when the angle of the stirring blade needs to be adjusted, the electric push rod 21 is activated: the push rod extends, pushing the linkage shaft 22 to move axially, causing the limiting block 25 to slide within the limiting groove 24 of the driven gear 23. The displacement of the linkage shaft 22 forces the transmission arm 33 to deflect, and the stirring rod 35 deflects around the ball head 37 as the fulcrum, causing the meshing position of the adjusting gear 36 and the linkage gear 31 to change synchronously. At this time, the rotation angle of the stirring rod 35 is α2, and the stirring blade rotates around the rotation diameter L2 of the ball head 37, thereby achieving the effect of changing its stirring angle.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
