Description
Technical Field

[0002] Corundum brick is a high-performance refractory material, and its main component is alumina (Al2O3). It is widely used in the lining and protection of various high-temperature industrial equipment due to its excellent high-temperature resistance and corrosion resistance, such as steel smelting furnaces, glass kilns, cement kilns, ceramic kilns, etc.
[0003] In related technologies, for the preparation of corundum bricks, in order to ensure that the product has uniform chemical composition and particle distribution, and to adjust the physical properties of the product, various raw materials usually need to be mixed, and after mixing, processes such as forming and sintering are carried out, and finally a corundum brick product with excellent performance is formed.
[0004] For the mixing of raw materials for corundum bricks, stirring blades are usually used to stir the raw materials in the mixing barrel to make the raw materials mixed. However, due to the high hardness of some raw materials (such as alumina, corundum ore, etc.), and due to process limitations in the preparation of raw materials, the particle size of the raw materials is uneven. When the raw materials are mixed, the high-hardness raw materials with larger particle sizes will cause impact and wear on the equipment, affecting the long-term stable operation of the equipment. And when stirring is carried out by a single stirring blade, due to the single stirring state, the mixing efficiency of the raw materials is low, and only by extending the stirring time can the stirring be made more sufficient.

Detailed implementation manners
[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0026] The fused alumina brick raw material mixing device according to the embodiments of the present utility model will be described below with reference to the drawings.
[0027] As Figures 1 to 4 shown, the fused alumina brick raw material mixing device according to the embodiments of the present utility model may include a mixing barrel 100, a grinding structure 200, a main mixing structure 300, a sub-mixing structure 400, and a transmission structure 500.
[0028] Among them, the grinding structure 200, the main mixing structure 300, and the sub-mixing structure 400 are all arranged inside the mixing barrel 100.
[0029] As Figure 5 shown, the grinding structure 200 includes a grinding chamber 210, grinding balls 220, a drive shaft 230, and a drive motor 240.
[0030] Among them, the grinding chamber 210 is arranged above inside the mixing barrel 100. As Figure 6 shown, the grinding chamber 210 includes an arc plate 211 that contracts towards the center and a grinding chamber 212 arranged at the central position. A plurality of sieve holes 2111 are formed in the arc plate 211, and a plurality of filter holes 2121 are formed in the grinding chamber 212.
[0031] As a possible case, the aperture of the sieve holes 2111 is larger than the aperture of the filter holes 2121. When mixing the fused alumina brick raw materials, by pouring the raw materials onto the grinding chamber 210, the raw materials with smaller particle sizes fall through the sieve holes 2111, while the raw materials with larger particle sizes stay on the grinding chamber 210 and roll into the grinding chamber 212.
[0032] The driving motor 240 is arranged outside the mixing barrel 100. One end of the driving shaft 230 is connected to the driving motor 240, and the other end passes through the grinding chamber 212 and extends downward. The grinding balls 220 are rotatably arranged in the grinding chamber 212 and are connected to the driving shaft 230.
[0033] It can be understood that there is a gap between the grinding balls 220 and the inner wall of the grinding chamber 212 to ensure that the raw materials with large particle size roll into the grinding chamber 212 from the gap and are ground by the grinding balls 220, so as to form raw materials with small particle size and fall from the sieve holes 2111.
[0034] The main mixing structure 300 is arranged below the grinding structure 200, and the power input end of the main mixing structure 300 is coaxial with the driving shaft 230, so as to drive the main mixing structure 300 to work through the rotation of the driving shaft 230.
[0035] A plurality of auxiliary mixing structures 400 are arranged outside the main mixing structure 300 at equal angles and are respectively connected to the main mixing structure 300 through a transmission structure 500.
[0036] It should be noted that the relevant personnel can increase the number of the auxiliary mixing structures 400 according to specific needs, which is not limited here.
[0037] Specifically, when the relevant staff mix the raw materials of the corundum brick, first, the relevant staff pour the raw materials into the mixing barrel 100. Then, the raw materials are blocked by the grinding cavity 210, and the raw materials with small particle size fall from the sieve holes 2111 of the arc plate 211, while the raw materials with large particle size roll into the grinding chamber 212.
[0038] The relevant staff start the driving motor 240, so that the driving motor 240 drives the grinding balls 220 on the driving shaft 230 to grind the large-particle raw materials in the grinding chamber 212 until the large-particle raw materials are crushed and fall from the filter holes 2121. As the particle size of the mixed raw materials becomes smaller, the impact and friction of the raw materials on the equipment are weakened, thereby improving the operation stability and service life of the equipment.
[0039] At the same time, the driving shaft 230 drives the main mixing structure 300 to stir the raw materials in the mixing barrel 100, and the main mixing structure 300 drives a plurality of auxiliary mixing structures 400 to work simultaneously through the transmission structure 500, so that the raw materials are stirred multiple times. Moreover, the linkage effect between the main mixing structure 300 and the plurality of auxiliary mixing structures 400 can increase the stirring complexity in the mixing barrel 100, make the raw materials stirred more fully, reduce the stirring time, and improve the mixing efficiency of the raw materials.
[0040] In an embodiment of the present utility model, both the main mixing structure 300 and the auxiliary mixing structure 400 include a rotating shaft 310 and a stirring blade 320.
[0041] Among them, a plurality of stirring blades 320 are sequentially arranged along the length direction of the rotating shaft 310.
[0042] The rotating shaft 310 of the main mixing structure 300 is coaxially connected to the driving shaft 230, and the rotating shaft 310 of the auxiliary mixing structure 400 passes upward through the arc-shaped plate 211 and is rotatably connected to the inner wall of the top of the mixing barrel 100.
[0043] It should be noted that the stirring of both the main mixing structure 300 and the auxiliary mixing structure 400 is achieved by the rotation of the stirring blades 320.
[0044] As a possible situation, the stirring blades 320 of the main mixing structure 300 and the stirring blades 320 of the auxiliary mixing structure 400 are arranged in a staggered manner. By arranging the stirring blades 320 in a staggered manner, the stirring blind area in the mixing barrel 100 can be reduced, and since the stirring blades 320 are arranged in a staggered manner, longer blades can be selected for the stirring blades 320, which can make the mixing efficiency higher.
[0045] In an embodiment of the present invention, the transmission structure 500 includes a driving pulley 510, a driven pulley 520, and a synchronous belt 530.
[0046] Among them, the driving pulley 510 is coaxially connected to the rotating shaft 310 of the main mixing structure 300, the driven pulley 520 is coaxially connected to the rotating shaft 310 of the corresponding auxiliary mixing structure 400, and the synchronous belt 530 is sleeved outside the driving pulley 510 and the driven pulley 520.
[0047] It should be noted that as the driving shaft 230 rotates, it can drive the rotation of the rotating shaft 310 on the main mixing structure 300. Thus, the driving pulley 510 rotates accordingly, and then the synchronous belt 530 can transmit the power to the rotating shaft 310 of the auxiliary mixing structure 400, thereby driving the rotation of the auxiliary mixing structure 400.
[0048] To clearly illustrate the previous embodiment, in an embodiment of the present invention, the diameter of the driving pulley 510 is larger than the diameter of the driven pulley 520.
[0049] It should be noted that by setting the driving pulley 510 and the driven pulley 520 with different diameters and providing different numbers of teeth on the driving pulley 510 and the driven pulley 520, the transmission ratio of the driving pulley 510 and the driven pulley 520 is changed, thereby changing the rotation speed of the auxiliary mixing structure 400.
[0050] As a possible situation, the transmission ratio of the driving pulley 510 to the driven pulley 520 is 1:3.
[0051] When the main mixing structure 300 mixes and stirs the raw materials, the auxiliary mixing structure 400 can mix and stir at three times the speed. Thus, the mixing state of the raw materials can be more complex, including effects such as cyclic mixing, shearing, and turbulence, thereby promoting the uniform mixing and reaction of the raw materials.
[0052] In an embodiment of the present utility model, a feed inlet 101 is provided at the top of the mixing barrel 100, a discharge outlet 102 is provided at the bottom of the mixing barrel 100, and a valve switch is provided on the discharge outlet 102. Relevant staff can control whether the mixed raw materials are discharged by opening and closing the valve switch.
[0053] In addition, support legs 103 for supporting the entire device are provided at the bottom of the mixing barrel 100.
[0054] In summary, for the corundum brick raw material mixing device according to the embodiment of the present utility model, by providing the grinding structure 200, the raw materials with large particle sizes can be ground, so that the raw materials can participate in the mixing with smaller particle sizes, reducing the impact and wear of the raw materials on the equipment and improving the stability of the equipment operation. In addition, by providing the auxiliary mixing structure 400 outside the main mixing structure 300, the raw materials can present a more complex motion state, reducing the stirring time and improving the stirring efficiency.
