Description

A device for separating the slag removal amount in a lead furnace for casting power battery plates Technical Field

[0001] This utility model relates to the field of power battery production technology, specifically to a slag removal separation device for a lead furnace casting plate of a power battery. Background Technology

[0002] In a lead casting furnace, molten lead needs to be slag removed periodically. During slag removal, the lead slag on the surface of the molten lead needs to be skimmed off using tools. After the lead slag in the molten lead is skimmed off, lead slag will still be generated on the surface of the molten lead in the furnace. When the lead slag is skimmed off, the molten lead mixed in with the lead slag is also skimmed off. After multiple slag removals, the amount of molten lead mixed in with the lead slag increases, resulting in a large loss of molten lead.

[0003] To address the aforementioned issues, patent document CN216801631U discloses a slag removal separation device for a lead furnace used for casting power battery plates. The device includes a circular hoop support with an outer diameter equal to the inner diameter of the lead furnace. The circular hoop support is divided into a lead slag removal area, a lead feeding area, and a lead waste addition area by radially symmetrically arranged arc-shaped partitions. The lead feeding area and the lead waste addition area have the same area. The top edge of the circular hoop support is detachably fixed to the top opening of the lead furnace via at least three circumferentially spaced suspension mechanisms. This device effectively isolates the lead alloy molten surface in the lead furnace into three zones: a lead slag removal zone for specifically removing lead slag, a lead feeding zone for adding lead alloy, and a lead waste addition zone for adding scrap scrap from the cast plate edges. During production, lead slag from the lead feeding and waste addition zones (which are higher than the lead furnace slag removal separation device) can be transferred to the lead slag removal zone. This also ensures an appropriate lead slag thickness in both zones, preventing over-removal of lead slag and excessive oxidation, thus reducing lead alloy loss. However, even after installation, the device still requires tools to transfer lead slag, lacking a dedicated slag transfer function, and adjusting its height within the lead pot is cumbersome. Summary of the Invention

[0004] The main purpose of this utility model is to provide a slag removal separation device for a power battery casting plate lead furnace with convenient height adjustment and slag scraping function.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A slag removal separation device for a lead furnace for casting power battery plates includes an inner ring. Arc-shaped plates are fixed to both sides of the inner ring, with their opening directions opposite. A slag removal zone is formed between the two arc-shaped plates and the inner ring. A feeding zone is formed between one arc-shaped plate and the inner ring, and a waste addition zone is formed between the other arc-shaped plate and the inner ring. A slag scraping assembly is provided at the upper end of the inner ring portion opposite to the arc-shaped plates. The two slag scraping assemblies are symmetrical about the axis of the inner ring. Each slag scraping assembly includes a scraper, one end of which is fixedly connected to a rotating rod. The rotating rod is rotatably connected to the inner ring. A blocking assembly is provided on the rotating rod, which can be blocked by the upper end of the lead furnace during the process of the inner ring being lowered into the lead furnace.

[0007] Specifically, the scraper is arc-shaped, and the arc-shaped scraper is concentric with the inner ring.

[0008] Specifically, the upper end of the inner ring is flush with the upper end of the arc-shaped plate, and the lower end of the scraper is in contact with the upper end of the inner ring.

[0009] Specifically, after the inner ring is located inside the lead furnace, the outer edge of the inner ring contacts the inner edge of the lead furnace.

[0010] Specifically, the blocking assembly includes a retaining ring sleeved on the outside of the rotating rod, and two nuts are threadedly connected to the rotating rod above the retaining ring. During the process of the inner ring being lowered into the lead furnace, the retaining ring is blocked by the upper end of the lead furnace.

[0011] Specifically, a handle is fixed to the upper end of the rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By incorporating a blocking component, the height of the inner ring within the lead furnace can be quickly and precisely adjusted. Adjustment requires only rotating the nut to lock the position, eliminating the need for disassembly or complex operations. This solves the problem of cumbersome adjustments inherent in traditional devices and significantly improves operational efficiency.

[0014] 2. The centrally symmetrical arc-shaped scraper assembly is linked to the handle via a rotating rod. Operators can manually rotate the scraper to scrape the lead slag from the feeding area and waste addition area into the slag removal area, reducing the steps of manually transferring lead slag and lowering labor intensity.

[0015] 3. The slag removal zone, feeding zone, and waste addition zone are separated by an arc-shaped plate with opposite openings. The thickness of the lead slag in each zone is dynamically controlled by a slag scraping assembly. This prevents excessive slag removal from accelerating the oxidation of the lead liquid and allows for the melting and recovery of unoxidized lead liquid in the slag removal zone through high-temperature calcination.

[0016] 4. The slag scraping, zoning, and height adjustment functions are integrated into a single device, reducing reliance on additional tools. The double-nut anti-loosening design ensures long-term stability. Attached Figure Description

[0019] The parts in the attached diagram are named as follows: 1. Lead furnace; 2. Inner ring; 3. Arc plate; 4. Scraper; 5. Rotating rod; 6. Retaining ring; 7. Nut; 8. Handle; 9. Slag removal area; 10. Feeding area; 11. Waste addition area. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Referring to Figures 1-2, a slag removal separation device for a lead furnace casting plate for power batteries includes an inner ring 2. Arc-shaped plates 3 are fixed on both sides of the inner ring 2. The upper ends of the inner ring 2 and the upper ends of the arc-shaped plates 3 are flush. The opening directions of the two arc-shaped plates 3 are opposite. A slag removal zone 9 is formed between the two arc-shaped plates 3 and the inner ring 2. A feeding zone 10 is formed between one arc-shaped plate 3 and the inner ring 2, and a waste material addition zone 11 is formed between the other arc-shaped plate 3 and the inner ring 2.

[0022] A slag scraping assembly is provided at the upper end of the inner ring 2 part opposite to the arc plate 3, and the two slag scraping assemblies are symmetrical about the axis center of the inner ring 2.

[0023] The slag scraping assembly includes a scraper 4, which is arc-shaped and concentric with the inner ring 2. The lower end of the scraper 4 contacts the upper end of the inner ring 2.

[0024] One end of the scraper 4 is fixedly connected to the rotating rod 5, the rotating rod 5 is rotatably connected to the inner ring 2, and a handle 8 is fixed at the upper end of the rotating rod 5.

[0025] A blocking component is provided on the rotating rod 5. During the process of lowering the inner ring 2 into the lead furnace 1, the blocking component can be blocked by the upper end of the lead furnace 1. After the inner ring 2 is located inside the lead furnace 1, the outer edge of the inner ring 2 contacts the inner edge of the lead furnace 1.

[0026] Based on the height of the inner ring 2 in the lead furnace 1, the height of the lead liquid level in the lead furnace 1 is set so that the lead liquid level is flush with the lower end of the inner ring 2.

[0027] When the lead slag produced in the lead furnace 1 exceeds the upper end of the inner ring 2, the handle 8 causes the rotating rod 5 and scraper 4 to rotate. When the two scrapers 4 rotate, they can scrape the lead slag in the feeding area 10 and the waste addition area 11 into the slag removal area 9, while ensuring the thickness of the lead slag on the surface of the lead liquid in the feeding area 10 and the waste addition area 11, and avoiding excessive slag removal.

[0028] When too much lead slag accumulates in the slag removal area 9, simply remove the lead slag from the slag removal area 9 to avoid wasting molten lead due to repeated slag removal.

[0029] Because the lead slag is calcined at high temperature in the slag-making area for a long time, the unoxidized part of the lead slag is melted into liquid lead after high-temperature calcination and can be reused.

[0030] Example 2: Based on Example 1, referring to Figures 1 and 2, the blocking assembly includes a retaining ring 6 sleeved on the outside of the rotating rod 5. Two nuts 7 are threaded onto the rotating rod 5 above the retaining ring 6. During the process of the inner ring 2 being lowered into the lead furnace 1, the retaining ring 6 is blocked by the upper end of the lead furnace 1.

[0031] When it is necessary to adjust the height of the inner ring 2 inside the lead furnace 1, simultaneously rotate the two lower nuts 7. As the lower nuts 7 rotate downwards, the inner ring 2 and the rotating rod 5 will rise because the retaining ring 6 is blocked by the upper end of the lead furnace 1. After the height of the inner ring 2 is adjusted, rotate the upper nut 7 so that the upper nut 7 is tightly pressed against the lower nut 7, thereby locking the lower nut 7. During the rotation of the rotating rod 5, the two nuts 7 rotate with the rotating rod 5, which can prevent the lower nut 7 from rotating relative to the rotating rod 5 and affecting the height positioning of the inner ring 2.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
