Description

Technical Field

[0001] The utility model relates to the field of sintering equipment, in particular to a sintering machine trolley with high sealing and dust-proof performance. Background Art

[0002] A sintering machine trolley is an important device used in the sintering process. It is mainly used to convert various raw materials into sintered bodies with certain shapes and properties through a high-temperature sintering process. The sintering machine trolley is usually made of high-temperature-resistant materials and can withstand a long-term high-temperature environment without deformation or damage. During the sintering process, the trolley moves along a predetermined path in the sintering furnace to ensure that the raw materials are evenly heated, thereby achieving a high-quality sintering effect. The design and manufacture of the sintering machine trolley need to consider various factors such as temperature distribution, thermal expansion, and corrosion resistance to ensure its reliability and stability in practical applications.

[0003] The sealing performance of traditional sintering machine trolleys is poor, which easily leads to dust pollution and deterioration of the working environment, affecting the sintering quality and the service life of the equipment. Sealing is the core of the design of sintering machine trolleys. Usually, the sintering table is made into an integrated structure to improve the dust-proof effect, reduce material loss, and prevent unnecessary heat dissipation. Therefore, the optimization of the dust-proof and sealing performance of most sintering machine trolleys is particularly important. In the prior art, the bottom of the sintering machine trolley is usually sealed with a dust-proof sealing strip, but this method has certain limitations. Especially at extremely high temperatures, residues will remain on the grate bars when the sintering machine transports minerals. There will be gaps between the grate bars, and materials will leak out. Usually, the grate bars are not easy to clean. For the sake of sealing performance, both the grate bars and the bottom of the sintering machine trolley are of an integrated structure, resulting in increased difficulty in maintenance and cleaning and affecting production efficiency. Therefore, the utility model proposes a sintering machine trolley with high sealing and dust-proof performance. Summary of the Utility Model

A wheel 12 is installed on the vehicle rod 11. A triangular support plate 13 is installed on the top of the vehicle rod 11. A hollow box 14 is welded and installed on the top of the triangular support plate 13. A third through hole 15 is arranged on the top of the hollow box 14;

[0031] Side plates 18, a plurality of third through holes 15 are arranged at the bottom of the side plates 18. Second positioning screws 16 are installed in the plurality of third through holes 15, and first nuts 17 are installed on the second positioning screws 16. The second positioning screws 16 fix the side plates 18 on the frame 10. Through fourth holes 19 are arranged on both sides of the side plates 18;

[0032] A bottom plate 4, the bottom plate 4 is installed at the bottom of the trolley main body 1. Rotating rods 6 are arranged on both sides of the bottom plate 4. The rotating rods 6 are installed in the first through holes 5. Fixing plates 8 are arranged on both sides of the bottom plate 4 away from the rotating rods 6. Second through holes 7 are arranged on the fixing plates 8. First positioning screws 9 are installed in the second through holes 7. The first positioning screws 9 fix the bottom plate 4 on the inner side of the frame 10 through the second through holes 7.

[0033] In this embodiment, a plurality of hollow grooves 2 are provided in the trolley body 1. The function of the hollow grooves 2 is to support the grate bars 3 and at the same time maintain a hollow space with the material through the grate bars 3. A bottom plate 4 is provided at the bottom of the hollow grooves 2. There are two side plates 18, which are both installed on the frame 10 on both sides of the trolley body 1. The function of the bottom plate 4 is to seal the inside of the trolley body 1. When the trolley body 1 is working, the first positioning screw 9 is used to fix the bottom plate 4 to the inner side of the frame 10 through the second through hole 7, ensuring the sealing performance of the bottom of the trolley body 1. At the same time, when the trolley needs to be repaired and cleaned, the first positioning screw 9 is unscrewed from the second positioning hole, and the bottom plate 4 is opened, so that the residue in the hollow groove 2 can be cleaned. This not only ensures the sealing performance of the trolley body 1 but also facilitates the cleaning of the residue in the hollow groove 2, improving production efficiency. At the same time, frames 10 are provided on both sides of the trolley body 1, and side plates 18 are installed above the frames 10 through second positioning screws 16. The inner side of the side plates 18 is arc-shaped, reducing the direct contact between the side plates 18 and the material, reducing the wear of the side plates 18, and enabling the side plates 18 to better guide the flow of the material during operation, reducing the possibility of blockage, ensuring that the trolley material is evenly spread in the vehicle body, ensuring the sealing performance, and making the sintered material more pure.

[0034] Specifically, the trolley body 1 is the first trolley 22, and the second trolley 23 is connected to one side of the first trolley 22.

[0035] In this embodiment, the second trolley 23 is connected to one side of the first trolley 22. The trolleys are closely connected to each other to ensure that the transported material does not leak.

[0036] Specifically, a third positioning screw 20 is installed in the fourth through hole 19, a second nut 21 is installed on the third positioning screw 20, and the third positioning screw 20 fixes the first trolley 22 and the second trolley 23 through the fourth positioning hole.

[0037] In this embodiment, the third positioning screw 20 fixes the first trolley 22 and the second trolley 23 through the fourth positioning hole. When the sintering trolley is working, the position with the worst sealing performance is the position of the adjacent side plates 18. Connecting the adjacent side plates 18 together through the second positioning screws 16 can minimize the influence of air leakage from the side plates 18 on the sintered material.

[0038] Specifically, a plurality of hollow boxes 14 are provided on the outer side of the side plates 18.

[0039] In this embodiment, the function of setting multiple hollow slots 2 is to better reduce the influence of wind resistance on the trolley body 1. The design of the hollow box 14 not only reduces the weight of the side plate 18, but also helps to evenly distribute heat during the sintering process, further optimizing the sintering quality of the material. In addition, this design enables the side plate 18 to disperse pressure through the hollow box 14 when bearing the pressure of the material, enhancing the stability and durability of the side plate 18, reducing the maintenance cost, and improving the working efficiency and economic benefits of the entire trolley.

[0040] Specifically, grate bars 3 are installed in the slots of the hollow box 14. There are multiple grate bars 3, all of which are evenly hung in the hollow slots 2.

[0041] In this embodiment, multiple grate bars 3 are installed, all of which are installed in the hollow slots 2. The function of the grate bars is to form a trough-shaped space with the hollow slots 2 in the trolley body 1 to accommodate and carry the material.

[0042] Specifically, the second through hole 7, the third through hole 15, and the fourth through hole 19 are all threaded holes. The second through hole 7 is threadedly connected to the first positioning screw 9, the third through hole 15 is threadedly connected to the second positioning screw 16, and the fourth through hole 19 is threadedly connected to the third positioning screw 20.

[0043] In this embodiment, the threaded connection design makes the assembly and disassembly of each component more convenient, which helps to improve the maintenance efficiency. At the same time, this structure also enhances the connection stability, ensuring that it will not loosen due to vibration during the operation of the trolley. The first positioning screw 9, the second positioning screw 16, the third positioning screw 20, the first nut 17, and the second nut 21 are all made of high-temperature resistant materials.

[0044] Specifically, it is characterized in that: the bottom plate 4 has a chamfering treatment on the side close to the rotating rod 6.

[0045] In this embodiment, a chamfer is provided on one side of the side plate 18 to facilitate the smooth docking of the rotating rod 6, reduce the wear caused by sharp edges, and extend the service life of the equipment.
