Description

Technical Field

[0001] This utility model relates to the field of sintering production technology, and in particular to a novel pellet feeding device. Background Technology

[0002] In the mining and metallurgical fields, pelletizing is one of the important methods for agglomerating ore fines. When studying pellets in laboratories, green pellets made with different proportions are dried and preheated in a roasting furnace. The compressive strength and metallurgical properties corresponding to various roasting temperatures are then studied, along with the roasting temperatures required to obtain finished pellets with a strength of over 2000 Newtons. This allows for the selection of the optimal method and optimization of production parameters. Most simple pelleting laboratories use horizontal roasting furnaces, while some research institutes have built expensive experimental rotary kilns to simulate the roasting atmosphere of the production site, conducting roasting parameter optimization and pelletizing scheme research. Although both methods simulate the roasting time and temperature of a rotary kiln in a production site—the second method even simulating the actual roasting atmosphere—the significant differences between drying / preheating and the actual heating of each pellet in steel mill production mean that the experimental data cannot adequately guide on-site production operations in steel mills.

[0003] To address the aforementioned issues, a method can be adopted whereby green pellets produced in the laboratory are transferred to the steel mill site for subsequent experimental procedures (chain grate drying and preheating, rotary kiln calcination, and annular cooler cooling). This ensures that the research data obtained through real-world production testing closely approximates actual production data, thus better guiding production. The transfer of green pellets requires the use of a specific device (feeding cage). The feeding cage is used to load the green pellets through the production process on the steel mill's equipment. Afterward, the feeding cage is removed, and the pellets inside are subjected to physical tests such as compressive strength and metallurgical performance tests such as reduction expansion index and reduction degree index to obtain relevant data.

[0004] Current pellet feeding cage structures are simple and cannot adapt to raw pellets of different sizes, resulting in low flexibility in use. Therefore, this invention proposes a novel pellet feeding cage device to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a novel pellet feeding cage device. This device utilizes a movable ring frame at the bottom of multiple fixed ring frames, which is slidably connected to the fixed column frame. Multiple sets of extended columns and a mesh bottom plate are detachably installed. When accommodating different sizes of green pellets, the size of the holes on the side wall of the entire feeding cage can be adjusted by increasing or decreasing the number of extended columns and moving the installation position of the movable ring frame, thereby adapting to different sizes of green pellets.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel pellet casting device includes a mesh bottom plate, a mesh cover plate, a ring-shaped fixing frame, and a column fixing frame. The top of the mesh bottom plate is provided with a column fixing frame, and four sets of the column fixing frames are provided at equal angles. Multiple sets of the ring-shaped fixing frames are provided, and all sets of the ring fixing frames are located outside the four sets of column fixing frames. A mesh cover plate is detachably provided above the four sets of column fixing frames.

[0008] The bottom of the multiple sets of fixed ring frames is provided with movable ring frames, which are slidably connected to the fixed column frames. The fixed ring frames are provided with first mounting holes, and the movable ring frames are provided with second mounting holes. Extended columns are provided in the longitudinal sets of the first and second mounting holes. The diameters of the first and second mounting holes are larger than the diameters of the extended columns. The lower ends of the extended columns are detachably installed with the mesh bottom plate.

[0009] A further improvement is that the outer wall of the ring-shaped movable frame is provided with a semi-circular groove that matches the position of the column fixed frame, and the ring-shaped movable frame is slidably connected to the column fixed frame through the semi-circular groove.

[0010] A further improvement is that: the column fixing frame is provided with fixing holes, there are multiple fixing holes, and fixing bolts are provided in the fixing holes; the semi-circular groove is provided with mating holes that are compatible with the fixing bolts.

[0011] A further improvement is that the movable ring frame is provided with connecting bolts, and the movable ring frame is connected to the bottom of the fixed ring frame through the connecting bolts.

[0012] A further improvement is that the lower end of the extended column is provided with a threaded post, the top of the mesh base plate is provided with a threaded hole, and the extended column is connected to the threaded post and the threaded hole.

[0013] A further improvement is that: the top of the column fixing frame is provided with a docking groove, the docking groove is provided with an assembly screw hole, the bottom of the mesh cover plate is provided with a docking post, and the top of the mesh cover plate is provided with an assembly bolt that matches the assembly screw hole.

[0014] The beneficial effects of this utility model are as follows: By setting a movable ring frame at the bottom of multiple sets of fixed ring frames and slidingly connecting the movable ring frame to the fixed column frame, and by setting multiple sets of extended columns and mesh bottom plates that can be detachably installed, when it is necessary to adapt to the needs of holding green balls of different sizes, the size of the holes on the side wall of the entire feeding cage can be adjusted by increasing or decreasing the number of extended columns and moving the installation position of the movable ring frame, thereby adapting to the needs of holding green balls of different sizes; the feeding cage structure of this utility model is simple, and the adjustment process is convenient and easy to operate, which can meet the actual production needs.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-3As shown in the figure, this embodiment proposes a novel pellet casting device, including a mesh base plate 1, a mesh cover plate 2, an annular fixing frame 3, and a column fixing frame 4. The top of the mesh base plate 1 is provided with a column fixing frame 4, which is arranged in four groups at equal angles. Multiple groups of annular fixing frames 3 are provided, and all groups of annular fixing frames 3 are arranged outside the four groups of column fixing frames 4. The mesh cover plate 2 is detachably provided above the four groups of column fixing frames 4. The bottom of the multiple groups of annular fixing frames 3 is provided with annular movable frames 5, which are slidably connected to the column fixing frames 4. The annular fixing frames 3 are provided with a first mounting hole 6, and the annular movable frames 5 are provided with a second mounting hole 7. An extension column 8 is provided in the longitudinal multiple groups of the first mounting holes 6 and the second mounting holes 7. The diameter of the first mounting holes 6 and the second mounting holes 7 is larger than the diameter of the extension column 8. The lower end of the extension column 8 is detachably installed to the mesh base plate 1. When using the novel pellet feeding device of this utility model, green pellets are fed in by opening the mesh cover plate 2, and then the mesh cover plate 2 is fixed. When it is necessary to use the feeding device to hold large-sized green pellets, the connection between the movable ring frame 5 and the fixed ring frame 3 can be maintained, and the number of installation sets of the extension columns 8 can be reduced, so that the size of the holes on the feeding body composed of the extension columns 8, the fixed column frame 4, the movable ring frame 5, and the fixed ring frame 3 can be increased. When it is necessary to use the feeding device to hold small-sized green pellets, the connection between the movable ring frame 5 and the fixed ring frame 3 can be separated, the movable ring frame 5 can be moved to a suitable position and connected to the fixed column frame 4, and then the number of installation sets of the extension columns 8 can be increased, so that the size of the holes on the feeding body can be reduced.

[0021] The outer wall of the annular movable frame 5 is provided with a semi-circular groove 9 that matches the position of the column fixed frame 4. The annular movable frame 5 is slidably connected to the column fixed frame 4 through the semi-circular groove 9. When the annular movable frame 5 moves up and down, it moves on the column fixed frame 4 through the semi-circular groove 9.

[0022] The column fixing frame 4 is provided with fixing holes 10, and there are multiple fixing holes 10. Fixing bolts 11 are installed in the fixing holes 10. The semi-circular groove 9 is provided with mating holes 12 that are adapted to the fixing bolts 11. When the ring movable frame 5 moves to a designated position on the column fixing frame 4, the position of the ring movable frame 5 can be fixed by connecting the fixing bolts 11 to the mating holes 12 in the semi-circular groove 9.

[0023] The movable ring frame 5 is equipped with connecting bolts 13, which connect it to the bottom of the fixed ring frame 3. The movable ring frame 5 can be moved by removing the connecting bolts 13.

[0024] The lower end of the extension column 8 is provided with a threaded post, and the top of the mesh base plate 1 is provided with a threaded hole 14. The extension column 8 is connected to the threaded post and the threaded hole 14. The above configuration allows for quick installation and disassembly of the extension column 8, and the installation stability of the extension column 8 is high.

[0025] The top of the column fixing frame 4 is provided with a docking groove 15, and the docking groove 15 is provided with an assembly screw hole 16. The bottom of the mesh cover plate 2 is provided with a docking post 17, and the top of the mesh cover plate 2 is provided with an assembly bolt 18 that matches the assembly screw hole 16. The above settings enable quick positioning and installation of the mesh cover plate 2.

[0026] This invention features a movable ring frame 5 at the bottom of multiple fixed ring frames 3, which is slidably connected to the fixed column frame 4. Multiple sets of extended columns 8 are detachably installed with the mesh base plate 1. When different sizes of green pellets need to be accommodated, the size of the holes on the side wall of the entire feeding cage can be adjusted by increasing or decreasing the number of extended columns 8 and moving the installation position of the movable ring frame 5, thus accommodating different sizes of green pellets. The feeding cage structure of this invention is simple, and the adjustment process is convenient and easy to operate, meeting actual production needs.
