Description

Technical Field

[0001] This utility model belongs to the field of lithium iron phosphate kiln loading technology, and particularly relates to a structure that improves the weight and accuracy of lithium iron phosphate kiln loading. Background Technology

[0002] The stability of the weighing in the potting machine is crucial for the sintering and crystallization process of materials. If the weight difference of the potted materials is too large, it will affect the performance distribution of the batch of materials. If the potting amount is larger than the required value, the core temperature will be relatively higher. During the reaction cycle in the constant temperature zone, its compaction and electrical properties will be significantly different compared with other standard weight materials. In addition, the core temperature will also increase accordingly when it exits the furnace in the cooling zone. Excessive exit temperature poses a risk of material oxidation, which is extremely risky for product quality.

[0003] During the filling process, bridging may occur in the sagger, leading to inaccurate feeding, affecting the stability of the filling weight, and affecting the filling capacity of the sagger. This also seriously affects the stability of product quality. Furthermore, the feeding baffle will remove the bridged material, resulting in waste. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a structure that improves the weight and precision of the filling of lithium iron phosphate kilns, thereby more accurately resolving the problems described above.

The structure includes a support frame located below the feeding pipe of a sagger loading machine. A lifting cylinder is fixedly connected to the lower surface of the support frame. The telescopic rod of the lifting cylinder is fixedly connected to a tray. A sagger is placed on the upper surface of the tray, located below the feeding pipe.

[0013] This utility model discloses a structure for improving the weight and accuracy of sagger loading in lithium iron phosphate kilns. It utilizes a vibrating motor and an annular rubber sleeve. Clamping cylinders on both sides push fixing blocks to clamp and fix the sagger from both sides. Simultaneously, the vibrating motor on the fixing blocks activates, causing the sagger to vibrate.

It is highly practical, has a wide range of applications, requires no modification to the sagger loading machine, and is more convenient. Attached Figure Description

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0019] like Figures 1-3As shown, this utility model provides a structure for improving the weight and accuracy of sagger loading in lithium iron phosphate kilns. The structure includes a support frame 1 located below the feeding pipe 2 of the sagger loading machine. A lifting cylinder 3 is fixedly connected to the lower surface of the support frame 1. The telescopic rod of the lifting cylinder 3 is fixedly connected to a tray 4. A sagger 5 is placed on the upper surface of the tray 4, located below the feeding pipe 2. Mounting frames 6 are fixedly connected to both sides of the support frame 1. Clamping cylinders 7 are fixedly connected to each mounting frame 6. The telescopic rod of the clamping cylinder 7 is fixedly connected to fixing blocks 8. Vibration motors 9 are mounted on both fixing blocks 8. The support frame 1 is placed below the feeding pipe 2 of the sagger filling machine. During use, the lifting cylinder 3 pushes the sagger 5 up to the feeding pipe 2, and the sagger filling machine begins to fill the sagger 5. After filling, the material in the sagger 5 will experience bridging, resulting in the material at the top being conical. At this time, the clamping cylinders 7 on both sides push the fixing blocks 8 to clamp and fix the sagger 5 from both sides. At this time, the vibration motor 9 on the fixing blocks 8 starts, causing the sagger 5 to vibrate and vibrate the material in the sagger 5, reducing the bridging phenomenon and facilitating precise control of the feeding amount. No modification to the sagger filling machine itself is required, making it more convenient.

[0020] like Figure 1 As shown, each of the two fixing blocks 8 has an arc-shaped groove on one side opposite to the other. The cross-section of the sagger 5 is circular. The arc-shaped groove matches the sagger 5. When the fixing block 8 contacts the sagger 5, the arc-shaped groove fits against the outside of the sagger 5, improving the clamping effect on the sagger 5.

[0021] like Figure 1 and Figure 2 As shown, a weighing instrument 10 is fixedly installed on the upper surface of the tray 4, and the sagger 5 is placed on the weighing instrument 10. When the sagger 5 is unloading, the weighing instrument 10 on the tray 4 weighs the material in the sagger 5 in real time, so as to facilitate the control of the unloading amount.

[0022] like Figure 1 and Figure 2 As shown, a tapered tube 11 is provided above the sagger 5. The tapered tube 11 is located on the feed pipe 2. When feeding, the tapered tube 11 is fitted between the sagger 5 and the feed pipe 2 to guide the material and prevent it from spilling out.

[0023] like Figure 2 As shown, a first rubber ring 12 is fixedly connected to the outer side of the feed tube 2. The first rubber ring 12 is fixedly connected to the upper end of the tapered tube 11, and a second rubber ring 13 is fixedly connected to the lower end of the tapered tube 11. The inner diameter of the second rubber ring 13 is the same as the inner diameter of the sagger 5. After the tapered tube 11 is fitted onto the sagger 5, when vibration occurs, the first rubber ring 12 and the second rubber ring 13 provide buffering to prevent the tapered tube 11 from colliding with the feed tube 2 during vibration, which would cause the tapered tube 11 or the feed tube 2 to deform.

[0024] like Figure 3As shown, the inner wall of the tapered tube 11 is provided with an annular groove, and an annular rubber sleeve 14 is fixedly connected in the annular groove. An air guide pipe 15 is fixedly connected to the tapered tube 11, and the air guide pipe 15 is connected to the annular rubber sleeve 14. The other end of the air guide pipe 15 is connected to an air pump. When the sagger 5 is vibrated, the lifting cylinder 3 can drive the tray 4 and the weighing instrument 10 to descend and separate from the sagger 5. During vibration, the air pump blows air into the annular rubber sleeve 14 through the air guide pipe 15, causing the annular rubber sleeve 14 to bulge and expand downward, flattening the material in the sagger 5 and quickly reducing the bridging phenomenon.

[0025] Working principle: The support frame 1 is placed below the feeding pipe 2 of the sagger machine. When in use, the lifting cylinder 3 pushes the sagger 5 to rise, and the sagger 5 is aligned with the conical pipe 11. The sagger machine starts to fill the sagger 5 with material. After filling, the clamping cylinder 7 pushes the fixing block 8 to clamp and fix the sagger 5 from both sides. The lifting cylinder 3 can drive the tray 4 and the weighing instrument 10 to descend. The vibration motor 9 starts to make the sagger 5 vibrate, which vibrates the material inside the sagger 5. The air pump blows air into the annular rubber sleeve 14 through the air guide pipe 15, which makes the annular rubber sleeve 14 bulge and expand downward, flattening the material inside the sagger 5.

Various modifications and variations can be made to this utility model by those skilled in the art.
