Description

Technical Field

[0001] The utility model belongs to the field of material crushing, and more specifically, relates to a mixing device for pellet mixture. The utility model also relates to feeding equipment for the pellet mixture. Background Art

[0002] Pelletization is a process for producing ore pellets. Pelletization, along with sintering, is a common process for refining iron ore in the steel industry. Pelletizing involves mixing finely ground iron ore concentrate or other iron-containing powders with a small amount of additives. The mixture is then moistened with water and rolled into balls in a pelletizing machine. The mixture is then dried and calcined to consolidate into spherical iron-containing materials with a desired strength and metallurgical properties.

[0003] After the raw materials are moistened with water, they form lumps during the batching process due to reasons such as the temperature or the high viscosity of the ingredients. As a result, the raw materials are easily stuck in the transportation channel, and after the raw materials enter the pelletizing machine, it is easy to cause the pellets to be uneven or too large. In detail, the ingredients have residual heat after being mixed in the mixer and steam-dried. During the transportation process through multiple belts, the ingredients clump due to reasons such as low temperature or high viscosity of the ingredients. The agglomerated ingredients enter the pelletizing disk during the pelletizing process, and the particle size exceeds the standard and is uneven. Moreover, after the mixture agglomerates, it disperses when passing through the tumble screen or during the vertical furnace firing process, and cannot form pellets. This has a serious adverse effect on the transportation and processing efficiency of the mixture, and urgently needs to be improved. Utility Model Content

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please also refer to Figures 1 to 3 The mixing device for pelletizing mixture provided by the present invention is now described. In general, the present invention mainly breaks up the agglomerated materials before entering the pelletizing machine by arranging a corresponding crushing device on the material conveying line of the pelletizing machine, so as to keep the size of the materials entering the pelletizing machine consistent.

[0034] Based on the above-mentioned inventive idea, a feasible implementation method is proposed. In detail, the mixing device of the pellet mixture in the utility model includes a crushing channel 1, a crushing rack 2 and a driving mechanism 3, wherein the crushing channel 1 has a feed port 11, a crushing space 12 and a discharge port 13 arranged in sequence along the up and down directions; the crushing rack 2 includes a rotating shaft 21 and a plurality of crushing arms 22, the rotating shaft 21 is arranged in the crushing space 12 and extends along the first horizontal direction, one end of the crushing arm 22 is connected to the rotating shaft 21, and the other end extends toward the inner wall of the crushing space 12; the driving mechanism 3 includes a bearing seat 31 and a driving motor 32, the rotating shaft 21 is rotatably connected to the side wall of the crushing channel 1 through the bearing seat 31, and the power output shaft of the driving motor 32 is drivingly connected to the rotating shaft 21.

[0035] Compared with the prior art, in the specific implementation process of this embodiment, as the material falls from the upstream feed belt into the feed port 11, the crushing rack 2 in the crushing space 12 rotates around the axis of the rotating shaft 21 driven by the drive motor 32. During the rotation of the crushing rack 2, the various crushing arms 22 on the rotating shaft 21 can crush the agglomerated materials in the falling process, preventing the agglomerated materials from entering the downstream pelletizing machine, so that the particle size of the materials before entering the pelletizing machine remains uniform, and solves the technical problem that the particle size of the existing agglomerated mixture exceeds the standard and is uneven after entering the pelletizing machine. At the same time, this embodiment can also prevent the agglomerated mixture from dispersing during the process of passing through the spherical screen or burning paper, and thus preventing the technical problem of being unable to form pellets, thereby improving the efficiency of the mixture in the production and transportation process.

[0036] Optionally, a preferred embodiment is proposed for the arrangement of the crusher arms 22 and the rotating shaft 21. Specifically, the crusher arms 22 extend through the rotating shaft 21 along their length, with both ends of the crusher arms 22 extending toward the inner wall of the crushing channel 1. The axes of two adjacent crusher arms 22 are perpendicular to each other. In this way, this embodiment can maximize the number of crusher arms 22 while ensuring the structural strength of the rotating shaft 21, thereby enhancing the crushing effect of the crusher frame 2 on agglomerated mixed materials. Preferably, in the above embodiment, the crusher frame 2 also includes a plug pin that simultaneously connects the crusher arm 22 and the rotating shaft 21 to secure the crusher arm 22 to the rotating shaft 21.

[0037] In one embodiment, each shredder arm 22 is perpendicular to the axis of the rotating shaft 21. In this way, the shredder arms 22 can be more easily assembled and disassembled on the rotating shaft 21, and the processing cost of the shredder arms 22 can be reduced.

[0038] Based on the above embodiment, a feasible implementation method is proposed. Specifically, to drive the rotation shaft 21, a drive motor 32 is disposed outside the crushing channel 1, and the axis of the power output shaft of the drive motor 32 is parallel to the axis of the rotation shaft 21, and the power output shaft is connected to the rotation shaft 21. With this arrangement, this embodiment can utilize the drive motor 32 to drive the rotation of the rotation shaft 21, thereby enhancing the crushing effect of the crushing frame 2 on the crushing of agglomerates. In addition, the crushing frame 2 can also mix the mixed material, making the distribution of the various components in the mixed material more uniform.

[0039] Furthermore, in one feasible embodiment, the outer wall of the crushing channel 1 is provided with a mounting location for the drive motor 32. The mounting location includes a mounting plate 14 and a support plate 15. The edge of the mounting plate 14 is connected to the crushing channel 1, and the mounting plate 14 is parallel to the horizontal direction. The drive motor 32 is located on the upper surface of the mounting plate 14. The top edge of the support plate 15 is connected to the lower surface of the mounting plate 14. The side edges of the support plate 15 are connected to the crushing channel 1, and the support plate 15 is parallel to the vertical direction. With this arrangement, the mounting plate 14 in this embodiment can be used to mount the drive motor 32, and the support plate 15 can provide support for the mounting plate 14, preventing vibration of the crushing rack 2 from loosening the connection between the mounting plate 14 and the drive motor 32.

[0040] Based on the above embodiment, a feasible implementation is proposed. Specifically, a first reinforcing rib 16 is provided on the inner side of the crushing channel 1. The length of the first reinforcing rib 16 is perpendicular to the axial direction of the rotating shaft 21. In this embodiment, the first reinforcing rib 16 enhances the overall structural strength of the crushing channel 1, preventing it from falling apart due to internal material devices or vibrations from the crushing rack 2. Preferably, in this embodiment, a crushing protrusion is formed on the side of the reinforcing rib facing the rotating shaft 21 to assist the crushing rack 2 in crushing the mixed material, thereby enhancing the crushing and mixing effect of the present invention on agglomerated materials.

[0041] In one embodiment, the horizontal width of the bottom of the crushing space 12 gradually decreases from top to bottom to collect and gather the crushed and stirred materials, and prevent the materials from falling everywhere after flowing out of the discharge port 13.

[0042] According to the above embodiment, the crusher rack 2 also includes a fixed crossbeam 23 fixedly mounted in the crushing space 12. The length of the fixed crossbeam 23 is perpendicular to the axial direction of the rotating shaft 21, and the rotating shaft 21 is rotatably connected to the middle portion of the fixed crossbeam 23. With this arrangement, this embodiment can enhance the structural rigidity of the stacking channel 1 through the fixed crossbeam 23, preventing damage to the crushing channel 1 during the mixing and crushing of materials, thereby improving the reliability and durability of the present invention during practical use. Preferably, to further stabilize the connection between the fixed crossbeam 23 and the crushing channel 1, two second reinforcing ribs 17 are provided on opposite sides of the crushing channel 1 in the horizontal direction, corresponding to the ends of the fixed crossbeam 23. In this embodiment, the two second reinforcing ribs 17 on either side of the crushing channel 1 enhance the structural strength of the crushing channel 1 where the fixed crossbeam 23 is mounted, preventing the fixed crossbeam 23, to which the crusher rack 2 is mounted, from shaking.

[0043] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0044] When the material passes through the crushing channel 1 from top to bottom, the crushing rack 2 in the crushing space 12 rotates around the axis of the rotating shaft 21 under the drive of the driving motor 32. When the crushing rack 2 rotates, the various crushing arms 22 on the rotating shaft 21 can crush the agglomerated materials in the falling process, preventing the agglomerated materials from entering the downstream pelletizing machine, so that the particle size of the materials before entering the pelletizing machine remains uniform. At the same time, the crushing rack 2 can stir the materials in the crushing channel 1 to make the materials more evenly mixed, solving the technical problem that the particle size of the existing agglomerated mixture exceeds the standard and is uneven after entering the pelletizing machine; at the same time, the utility model can also prevent the agglomerated mixture from dispersing during the process of passing through the tumble screen or burning paper, and thus cannot form pellets, thereby improving the efficiency of the mixture during production and transportation; in addition to the above-mentioned beneficial effects, the first reinforcing ribs 16 and the second reinforcing ribs 17 in this embodiment can enhance the structural strength of the crushing channel 1, wherein the first reinforcing rib 16 can also assist the crushing rack 2 to enhance the crushing effect of agglomerates and the mixing effect of the mixture.

[0045] Based on the same inventive concept, in another embodiment, the present invention further provides a pellet mixture feeding device, which includes the pellet mixture mixing device described above.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
