Technical Field

[0001] This utility model relates to the technical field of raw material processing devices, and in particular to a raw material processing device for preparing high-alumina sintered ore. Background Technology

[0002] Jaw crushers are key equipment in the raw material processing unit for high-alumina sinter preparation, primarily used to coarsely crush high-alumina ores (such as bauxite and kaolin) to a suitable particle size for sintering (typically 20-100mm). Their working principle involves the periodic squeezing motion of the moving jaw plate relative to the fixed jaw plate to crush the ore. The V-shaped crushing chamber design enhances the biting action on the material, improving crushing efficiency. This equipment is widely used in metallurgy, building materials, and other industries, and is a core component of raw material pretreatment in high-alumina sinter production lines.

[0003] Traditional jaw crushers have significant problems when crushing high-alumina ores: because the feed inlet faces upward and the crushing chamber has a V-shaped structure, the ore is easily ejected from the feed inlet by the rebound force during the compression process, which not only wastes raw materials but also threatens the safety of operators. There is an urgent need to improve the feed inlet structure and protection design of jaw crushers. Utility Model Content

[0005] Therefore, one objective of this utility model is to provide a raw material processing device for the preparation of high-alumina sintered ore, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a raw material processing device for preparing high-alumina sintered ore, comprising a first motor and a crusher body. A fixed jaw plate is fixedly connected to the inner wall of the crusher body. A flywheel is rotatably connected to the top of the crusher body via a bearing.

[0009] Preferably, in any of the above embodiments, a guide rod is fixedly connected to one end of the gear near the cylinder, and the guide rod is slidably connected to the feed frame.

[0010] Preferably, in any of the above embodiments, a rubber soft belt is fixedly connected to the side of the feed frame away from the connecting rod, and the side of the rubber soft belt away from the feed frame is fixedly connected to the moving jaw plate by bolts.

[0014] 1. This device effectively solves the problem of raw material rebound during the crushing of high-alumina ore by setting an adjustable feed frame structure. The specific operating steps are as follows: After the ore enters the feed frame, the second motor drives the drive rod to rotate, causing the baffle to form an adjustable material blocking structure within the feed frame; simultaneously, the cylinder pushes the toothed plate to rotate the gear, further adjusting the angle of the baffle. This design allows the baffle to automatically adjust the blocking angle according to the ore particle size and crushing force, forming a dynamic sealing structure in conjunction with the flexible connection of the rubber belt. Its beneficial effects are: firstly, it effectively prevents the ore from rebounding and flying out during the crushing process between the moving and fixed jaw plates, improving raw material utilization; secondly, through the synergistic effect of the baffle and the rubber belt, a safety barrier is formed at the feed inlet, significantly reducing the risk of injury to operators from ore splashing.

The specific operating steps are as follows: After loosening the two locking bolts to disengage them from the threaded holes, the operator can push the feed frame to rotate around the connecting rod, causing the feed frame to rotate axially along the connecting rod through the through hole, thus separating the feed frame from the crusher body. The beneficial effects of this structure are: firstly, it fully exposes the fixed jaw plate and the moving jaw plate, facilitating the cleaning of accumulated material in the crushing chamber and the inspection of wear; secondly, after the feed frame can be flipped to the maintenance position, workers can more safely and conveniently replace worn parts or adjust the clearance of the moving jaw plate, significantly improving equipment maintenance efficiency. Compared with the traditional fixed feed structure, it also reduces equipment downtime losses. Attached Figure Description

This design enables baffle 11 to automatically adjust the blocking angle according to the ore particle size and crushing force, forming a dynamic sealing structure in conjunction with the flexible connection of rubber soft belt 17.

[0033] 3): After loosening the two locking bolts 8 to disengage them from the threaded hole 19, the operator can push the feed frame 7 to rotate around the connecting rod 6, so that the feed frame 7 can rotate axially along the connecting rod 6 through the through hole 18, thereby separating the feed frame 7 from the crusher body 2.

[0034] In summary, this high-alumina sinter preparation raw material processing device effectively solves the problem of raw material rebound during the crushing process of high-alumina ore by setting an adjustable feed frame 7. The specific operating steps are as follows: when the ore enters the feed frame 7, the second motor 9 drives the drive rod 10 to rotate, causing the baffle 11 to form an adjustable material blocking structure within the feed frame 7; simultaneously, the cylinder 14 pushes the toothed plate 15 to drive the gear 13 to rotate, further adjusting the angle of the baffle 11. This design allows the baffle 11 to automatically adjust the blocking angle according to the ore particle size and crushing force, forming a dynamic sealing structure in conjunction with the flexible connection of the rubber soft belt 17. Its beneficial effects are: on the one hand, it effectively prevents the ore from rebounding upwards and flying out during the squeezing process between the moving jaw plate 5 and the fixed jaw plate 3, improving the raw material utilization rate; on the other hand, through the synergistic effect of the baffle 11 and the rubber soft belt 17, a safety protection barrier is formed at the feed inlet, significantly reducing the risk of injury to operators from ore splashing.
