Description

Technical Field

[0001] This utility model belongs to the field of sintering technology, specifically relating to a material blocking device with adjustable material drop point for sintered shuttle cloth. Background Technology

[0002] Sintering, as the most widely used, efficient, and high-capacity mature technology in long-process steel production, relies heavily on permeability as one of the most important indicators affecting the sintering process. It plays a decisive role in sinter yield, quality, and energy consumption. During the sintering shuttle feeding process, the lack of a proper adjustment mechanism for the material drop point leads to instability and segregation of the mixture in the ore bin, significantly impacting subsequent sintering permeability. This can result in poor permeability of the sintering surface, a decreased sintering permeability index, slow sintering speed, and a tendency for over-burning of the sinter, leading to reduced sinter yield. Simultaneously, it increases the negative pressure of the main pump, increases power consumption, and negatively affects sintering production. Therefore, proactive control and adjustment of the sintering shuttle feeding point are crucial. Utility Model Content

[0003] This invention provides a material blocking device with an adjustable material drop point for sintered shuttle cloth, which solves the problem of uncontrollable drop point of the existing shuttle cloth transport mixture, reduces material segregation in the ore bin, and achieves homogeneous sintering production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material-blocking device for adjustable sintering shuttle cloth material drop point, comprising a shuttle cloth frame, a material-blocking plate frame, a fixed seat, an adjusting rod, a material-blocking plate, and a material-blocking plate angle adjusting device. The material-blocking plate frame is fixed above the shuttle cloth frame, the fixed seat is fixed on the material-blocking plate frame, the adjusting rod is movably connected to the fixed seat, and the material-blocking plate is fixed below the adjusting rod and above the sintering ore bin. The material-blocking plate angle adjusting device includes an adjusting rod frame, a support rod, an adjusting pin, and a connecting seat. One end of the support rod is rotatably connected to the material-blocking plate, and the other end has a pin hole. The adjusting rod frame is fixed above the shuttle cloth frame, and the connecting seat is inclinedly fixed to the side of the adjusting rod frame. The connecting seat has a pin hole, and the connecting seat is connected to the other end of the support rod through the adjusting pin.

[0005] Preferably, the fixing base has a through hole into which an adjusting rod can be inserted.

[0006] Preferably, the adjusting rod has a structure with cylindrical ends and a cuboid in the middle.

[0007] Preferably, the shuttle frame is composed of two I-beams arranged in parallel above the sintering ore bin.

[0009] Preferably, the adjusting rod frame is an H-beam or channel steel structure, with both ends welded to the shuttle cloth frame.

[0010] Preferably, the baffle plate is covered with a wear-resistant liner.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The baffle plate is a solid wear-resistant plate located in the direction of the mixture's forward movement, and its angle with the mixture's trajectory is adjustable. By blocking the mixture's trajectory, it changes the drop point of the mixture inside the ore bin, thereby ensuring the flatness of the material surface inside the bin, reducing material segregation, and improving the uniformity of sintering distribution and combustion. The device has a simple structure, is easy to operate and adjust, and has good performance. The surface of the baffle plate is covered with wear-resistant liners, reducing equipment wear and extending the equipment's service life. Attached Figure Description
