Technical Field

[0001] This utility model relates to the field of sintering machine technology, specifically a sintering machine with an anti-wear structure. Background Technology

[0002] The sintering machine exhaust system is the most important component of sintering machine production. It is usually composed of a wind box, flap valve, compensator, suction elbow, dust collection pipe, flue, and main exhaust system. The compensator and suction elbow are usually operated in a negative pressure environment.

[0003] A search revealed that announcement number CN202393219U discloses a sintering machine flue gas compensator, belonging to the field of sintering machine technology. The compensator consists of a first outer annular plate as the main body, connected to a left-end connecting sleeve. The first outer annular plate is connected to a first crest connecting sleeve, which in turn is connected to a first inner annular plate. The first inner annular plate is connected to a trough connecting sleeve, which is connected to a second inner annular plate. The second inner annular plate is connected to a second crest connecting sleeve, which is connected to a second outer annular plate. The second outer annular plate is connected to a right-end connecting sleeve. During use, this flue gas compensator can be adjusted to the required size, reducing the air leakage rate of the sintering machine and improving its production efficiency.

[0004] The above-mentioned sintering machine flue compensator also has a problem. During the use of the sintering machine flue compensator, because the compensator is in a high negative pressure environment, the loose material at the tail end of the compensator is easily washed to its inner surface, causing the compensator to wear out and be damaged.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Please see Figures 1-5This embodiment provides a sintering machine with a wear-resistant structure, which includes a cylinder 1, a bent pipe 3, and a connecting platform 4. The bent pipe 3 is fixed to the top of the cylinder 1, and the connecting platform 4 is fixed to the bottom of the cylinder 1.

[0034] The aforementioned sintering machine with wear-resistant structure also includes a protective component, a connecting component, and a telescopic component. The protective component is located inside the cylinder 1; the connecting component is located at the bottom of the cylinder 1; and the telescopic component is located inside the connecting component.

[0035] Specifically, the protective components include a boss 21, a flow-blocking ring 22, a ceramic box 23, a wear-resistant coating 24, and a support rib 25. The boss 21 is fixed on the inner circumferential surface of the cylinder 1. The flow-blocking ring 22 is welded and fixed to the inner side of the boss 21. The ceramic box 23 is uniformly welded and fixed to the inner side of the flow-blocking ring 22. The inner side of the flow-blocking ring 22 is coated with a wear-resistant coating 24. A support rib 25 is uniformly fixed to one end of the bottom side of the flow-blocking ring 22. The support rib 25 is uniformly welded and fixed to the inner surface of the cylinder 1.

[0036] Furthermore, by combining the flow-blocking ring 22 with the ceramic box 23, the scouring of the tail suction elbow under the influence of high negative pressure on the bulk material can be reduced, thereby reducing the wear of the suction elbow and the compensator.

[0037] In use, the flow-blocking ring 22 is welded and fixed to the inner side of the cylinder 1 as required, and the bottom side of the flow-blocking ring 22 is uniformly welded and fixed to the cylinder 1. Then, the ceramic box 23 is uniformly welded and fixed to the inner side of the flow-blocking ring 22, and the wear-resistant coating 24 of the required thickness is applied to the inner side of the flow-blocking ring 22. At this time, it can prevent the bulk material from being washed to the inner wall of the cylinder 1 by the influence of high negative pressure, thereby reducing the wear of the compensator and the suction elbow and reducing the cost of equipment maintenance and replacement.

[0038] In summary, the structure of the protective components and the structure of the flow-blocking ring 22 can change the direction of the bulk material flow, preventing the bulk material from being eroded by high negative pressure on the suction elbow and the inner wall of the compensator. At the same time, the wear-resistant coating 24 covers the surface of the flow-blocking ring 22, making it more wear-resistant, thereby reducing the cost of equipment maintenance and replacement.

[0039] Specifically, the connecting components include a compensator body 51, a fixed platform 52, a fixed plate 53, a threaded rod 54, a connecting plate 55, a nut 56, and an expansion joint 57. The compensator body 51 is provided with the bottom end of the cylinder 1. The fixed platform 52 is fixed on the top side of the compensator body 51. An expansion joint 57 is fixedly connected between the fixed platform 52 and the connecting platform 4. The fixed plate 53 is evenly fixed on the circumferential surface of the fixed platform 52. The threaded rod 54 is rotatably inserted through the inner side of the fixed plate 53. The connecting plate 55 is evenly fixed on the bottom circumferential surface of the connecting platform 4. The threaded rod 54 passes through the connecting plate 55 and is rotatably installed with the nut 56.

[0040] Furthermore, the compensator is connected to the suction elbow through the structure of threaded rod 54 and nut 56, which is simple in structure and easy to disassemble and assemble, facilitating subsequent maintenance.

[0041] Specifically, the telescopic assembly includes a cylinder 61, a limiting groove 62, a limiting block 63, and a sleeve 64. The cylinder 61 is fixed on the top side of the fixed platform 52. The limiting groove 62 is evenly opened on the circumference of the cylinder 61. The sleeve 64 is slidably installed inside the limiting groove 62 through the limiting block 63. The sleeve 64 is fixed on the bottom side of the connecting platform 4. The sleeve 64 and the cylinder 61 are located inside the telescopic joint 57.

[0042] Furthermore, the structure of the cylinder 61 and the sleeve 64 covers the inner surface of the expansion joint 57 to prevent the expansion joint 57 from being damaged and leaking air due to excessive wear.

[0043] In use, the threaded rod 54 is inserted into the inner side of the fixed plate 53 and the connecting plate 55. A nut 56 is installed at one end of the threaded rod 54, and the nut 56 is located on both sides of the connecting plate 55. With the cooperation of the threaded rod 54, the fixed plate 53 and the connecting plate 55 are fixedly connected, thereby installing the compensator to one end of the cylinder 1. It is easy to disassemble and assemble, and convenient for subsequent maintenance. At the same time, a cylinder 61 and a sleeve 64 are provided on the inner side of the expansion joint 57. The sleeve 64 slides on the cylinder 61, thereby covering the inner surface of the expansion joint 57 to prevent it from being damaged due to excessive wear, and to ensure that the equipment can be used normally.

[0044] In summary, the structure of the connecting component and the telescopic component, along with the engagement of the threaded rod 54 and the nut 56, allows for quick assembly and disassembly of the compensator, improving the efficiency of subsequent maintenance and replacement. The cylinder 61 and the sleeve 64 prevent loose materials from scouring the surface of the telescopic joint 57, thus preventing damage to the telescopic joint 57 from affecting the normal operation of the equipment.
