Description

Technical Field

[0001] This utility model belongs to the technical field of sintering production line, and more specifically, it relates to a material guiding structure for a sintering machine. Background Technology

[0002] Currently, the sintering machine feed chute is manufactured as a single piece. As the receiving device for hot ore at the tail end of the sintering machine, it is an indispensable piece of equipment. Sintered ore falls from the sintering trolley, slides through the feed chute into the single-tooth roller crusher for crushing, during which the operating temperature reaches 600°C-700°C. The sintered ore impacts the feed chute structure. Due to the high temperature and impact of the sintered ore, the welds and back plate of the feed chute body suffer severe wear, requiring frequent welding repairs and reinforcement of the feed chute body and back plate, as well as replacement of scraper blocks. This results in a poor working environment, long construction time, increased workload for maintenance personnel, reduced production efficiency, short lifespan of the sintering machine feed chute structure, and high maintenance requirements. In summary, the shortcomings of the existing technology are: the back plate of the current feed chute structure is a single piece, using a single-sided welding process, without internal welding treatment. This leads to wear and deformation of the back plate of the feed chute body, making it prone to flipping out. The overall structural strength is insufficient, obstructing the sintering trolley from dropping material, and in severe cases, forcing the entire sintering machine to stop. Therefore, it affects the normal operation of the sintering machine.

[0003] There is a technology in the prior art entitled "A sintering machine tail guide trough" with publication (announcement) number "CN110736351A". This technology relates to a sintering machine tail guide trough and belongs to the field of sintering production equipment technology in the metallurgical industry. The technical solution is: it includes a trough (5) and a base (6). The trough (5) is fixed on the base (6). The trough (5) is composed of a back plate (12), two side plates (13) and a bottom plate (14). Multiple material feeding hoppers (9) are arranged in sequence from top to bottom inside the trough (5). The multiple material feeding hoppers (9) form a multi-level trapezoid. The back plate (12) inside the trough (5) is provided with a back plate buffer material hopper (10). The side plates (13) inside the trough (5) are provided with side plate buffer material hoppers (11). The back plate (12) outside the trough (5) is provided with a receiving trough (7). The beneficial effects of this invention are: it not only meets the requirements of the production process, is wear-resistant, impact-resistant, and has a service life of more than two years, but also enables the sintered ore to fall smoothly into the single-roll crusher, thereby improving the sintering machine's operating rate.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a sintering machine material guide structure that is simple in structure, effectively strengthens the back plate assembly, improves connection reliability, effectively adapts to the material conveying environment, improves service life, and reduces costs, in order to address the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a sintering machine material guiding structure, including a rotary material guiding hopper assembly. The rotary material guiding hopper assembly includes a rotary motor, which is connected to the hopper assembly body. Multiple back plate assemblies are arranged around the outer ring of the hopper assembly body. Each back plate assembly includes multiple back plates and multiple back plate crossbeams. Adjacent back plates are connected by a back plate crossbeam. The back plates and back plate crossbeams are fixedly connected by bolts. Welded parts are provided at the joint ends of the back plates and back plate crossbeams.

[0008] The backplate crossbeam includes an upper surface, a lower surface, and a connecting part, which are in the form of an I-beam structure.

[0009] The back plate and the lower part of the back plate crossbeam are connected to the base.

[0010] A stiffening rib is provided between the back plate and the base.

[0011] The lower part of the back plate is provided with a lower back plate retaining beam, and the upper part of the back plate is provided with an upper back plate retaining beam.

[0012] A hopper diagonal brace is provided between the back plate crossbeam and the base.

[0013] Each back panel has a hopper side panel on both sides.

[0014] The lower part of the base is fixedly mounted on the base plate.

[0015] The rotating feed hopper assembly has a feed trough body on its outer side.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The sintering machine feeding structure of this utility model includes a rotating feeding hopper assembly. This assembly includes a rotary motor connected to the hopper assembly body. By controlling the rotation of the rotary motor, the hopper assembly body rotates. Multiple backplate assemblies are arranged around the outer ring of the hopper assembly body. The reciprocating rotation of the hopper assembly body drives the backplate assemblies to reciprocate, allowing each backplate assembly to convey material onto the feeding trough near the rotating feeding hopper assembly. Through the reciprocating rotation of the hopper assembly body, each backplate sequentially conveys material. After each backplate completes its feeding, it rotates away, repeating this process continuously to achieve material conveying. To address the shortcomings of existing backplates, the structure of the backplate assembly is improved. Each backplate assembly includes multiple backplates and multiple backplate crossbeams. Adjacent backplates are connected by a backplate crossbeam, and the backplates and crossbeams are fixed together by bolts. A welded section is provided at the joint edge of the backplates and crossbeams. In this way, each backplate and its corresponding crossbeam are reliably connected by bolts, and the backplate and crossbeam are reliably fixed by welding. The backplate assembly is no longer a single piece, but rather multiple parts are fabricated, then connected and welded together to form the backplate assembly. High-strength bolts are used, and welding is performed after the bolt connections. The contact points between each backplate and its corresponding crossbeam can also be welded to form welded sections, thereby improving connection reliability, effectively increasing the overall structural strength and durability of the material guiding structure, extending its service life, eliminating the need for frequent downtime for replacements, and effectively improving operational efficiency.

[0026] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0027] As attached Figure 1 -Appendix Figure 6As shown, this utility model is a sintering machine material guiding structure, including a rotary material guiding hopper assembly 12. The rotary material guiding hopper assembly 12 includes a rotary motor connected to the hopper assembly body. Multiple back plate assemblies are arranged around the outer ring of the hopper assembly body. Each back plate assembly includes multiple back plates 2 and multiple back plate crossbeams 3. Adjacent back plates 2 are connected by a back plate crossbeam 3. The back plates 2 and back plate crossbeams 3 are fixedly connected by bolts 1. A welded part is provided at the joint edge of the back plates 2 and back plate crossbeams 3. This structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structural design, a rotary guide hopper assembly 12 is provided. The rotary guide hopper assembly 12 includes a rotary motor connected to the hopper assembly body. By controlling the rotation of the rotary motor, the hopper assembly body is driven to rotate. Multiple backplate assemblies are arranged around the outer ring of the hopper assembly body. The reciprocating rotation of the hopper assembly body drives the backplate assemblies to reciprocate, allowing each backplate assembly to convey material onto the guide trough body 11 near the rotary guide hopper assembly 12. Through the reciprocating rotation of the hopper assembly body, the backplates 2 of each backplate assembly sequentially convey material. After each backplate completes its feeding, it rotates away, repeating this process continuously to achieve material conveying. Furthermore, to address the shortcomings of existing backplates, the structure of the backplate assembly is improved. Each backplate assembly includes multiple backplates 2 and multiple backplate crossbeams 3. Adjacent backplates 2 are connected by a backplate crossbeam 2, and the backplates 2 and backplate crossbeams 3 are fixedly connected by bolts 1. Welded sections are provided at the joint edges of the backplates 2 and backplate crossbeams 3. In this way, each backplate 2 and its corresponding backplate crossbeam 3 are reliably connected by bolts 1, and the backplates 2 and backplate crossbeams 3 are reliably fixed by welding through the welded sections. In this way, the backplate assembly is no longer formed as a whole, but is made into multiple parts, which are then connected and welded to form the backplate assembly. The bolts 1 are high-strength bolts, and welding can be performed after the bolts 1 are connected. The mating parts of each backplate 2 and its corresponding backplate crossbeam 3 can also be welded, thereby improving the connection reliability, effectively increasing the overall structural strength and durability of the material guiding structure, extending its service life, eliminating the need for frequent downtime for replacement, and effectively improving operating efficiency. The sintering machine material guiding structure described in this utility model has a simple structure, effectively strengthens the backplate assembly, improves connection reliability, effectively adapts to the material conveying environment, extends service life, and reduces costs.

[0028] The backplate crossbeam 3 includes an upper surface 31, a lower surface 32, and a connecting part 33, which form an I-beam structure. This structure optimizes the backplate crossbeam's structure, resulting in high strength and effective connection of the backplate to form a backplate assembly.

[0029] The back plate 2 and the back plate crossbeam 3 are connected to the base 9 at their lower parts. A stiffening rib 6 is provided between the back plate 2 and the base 9. A hopper diagonal brace 7 is provided between the back plate crossbeam 3 and the base 9. In the above structure, the base 9, stiffening rib 6, and hopper diagonal brace 7 are all connected by welding, thereby effectively improving connection reliability and increasing the strength of the back plate assembly.

[0030] The back plate 2 is provided with a lower back plate retaining beam 4 at its lower part and an upper back plate retaining beam 5 at its upper part. The above structure, with its lower back plate retaining beam 4 and upper back plate retaining beam 5, reduces the impact of material blocks on the back plate during use, increasing overall strength and durability.

[0031] Each back plate 2 has a hopper side plate 10 on both sides. A guide trough body 11 is provided on the outer side of the rotating guide hopper assembly. In this structure, each back plate assembly has hopper side plates on both sides, making the hopper assembly U-shaped. This effectively allows material to fall from the back plate onto the guide trough body 11, preventing material from leaking out from the sides of the back plate 2. The base 9 is fixedly mounted on the base plate 8. In this structure, the base 9 is used to fix and connect the back plate 2, the hopper diagonal brace 7, and the hopper side plates 10. The hopper diagonal brace 7 increases the overall strength and durability.

[0032] The sintering machine material guiding structure of this utility model includes a rotating material guiding hopper assembly 12. The rotating material guiding hopper assembly 12 includes a rotary motor connected to the hopper assembly body. By controlling the rotation of the rotary motor, the hopper assembly body rotates. Multiple backplate assemblies are arranged around the outer ring of the hopper assembly body. The reciprocating rotation of the hopper assembly body drives the backplate assemblies to reciprocate, allowing each backplate assembly to convey material onto the guide trough body 11 near the rotating material guiding hopper assembly 12. Through the reciprocating rotation of the hopper assembly body, the backplates 2 of each backplate assembly sequentially convey material. After each backplate completes its feeding, it rotates away, repeating this process continuously to achieve material conveying. Furthermore, the structure of the backplate assembly is improved to address the shortcomings of existing backplates. Each backplate assembly comprises multiple backplates 2 and multiple backplate crossbeams 3. Adjacent backplates 2 are connected by a backplate crossbeam 2, and the backplates 2 and backplate crossbeams 3 are fixedly connected by bolts 1. Welding sections are provided at the joint edges of the backplates 2 and backplate crossbeams 3. In this way, each backplate 2 and its corresponding backplate crossbeam 3 are reliably connected by bolts 1, and the backplates 2 and backplate crossbeams 3 are reliably fixed by welding through the welding sections. In this way, the backplate assembly is no longer formed as a single piece, but rather multiple parts are manufactured separately, and then these parts are connected and welded to form the backplate assembly. The bolts 1 are high-strength bolts, and welding is performed after the bolts 1 are connected. The mating parts of each backplate 2 and its corresponding backplate crossbeam 3 can also be welded, thereby improving the connection reliability, effectively increasing the overall structural strength and durability of the material guiding structure, extending the service life of the structure, eliminating the need for frequent downtime for replacement, and effectively improving operational efficiency.
