Description

Technical Field

[0001] This utility model relates to the field of lead ingot casting machine technology, specifically a continuous casting device for a lead ingot casting machine. Background Technology

[0002] In the lead ingot production process, traditional lead ingot casting equipment has been widely used in domestic lead smelters, and the main operations of the lead ingot casting process have achieved varying degrees of mechanization or automation. However, some problems still exist in the existing technology and urgently need to be solved. For example, existing lead casting machines pour molten lead into a mold, which then solidifies and casts the ingot. However, the lead cools and solidifies slowly on the mold, thus reducing the production efficiency of lead ingots. In addition, existing lead casting machines cannot continuously pour lead into the mold, which in turn affects the production efficiency of lead blocks.

[0003] Taking utility model patent No. 202123432862.6 as an example, this patent discloses a continuous casting device for a lead ingot casting machine. It achieves continuous casting and cooling of molten lead through components such as a smelting furnace, lead discharge valve, lead discharge pipe, casting box, guide plate, conveyor, and cooling components. However, this device still has some shortcomings. First, the cooling efficiency of its cooling components is limited and cannot meet the needs of large-scale production. Second, the precision of the mold's conveying and moving position is not high enough, which can easily lead to uneven casting and affect the quality of the lead ingots. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous casting device for a lead ingot casting machine, comprising a drive component, a conveying component, a primary cooling component, multiple supporting components, four drive components, and a concrete foundation cast from concrete components. The central and end regions of the concrete foundation are planar sections, with the edges of the end regions gradually sloping downwards towards the central region. The central region of the concrete foundation forms a water storage tank. All four drive components are mounted on the concrete foundation, with two drive components fixedly mounted in the central region and the other two fixedly mounted in the end regions. The conveying component is a chain structure with its ends connected, fitted onto each drive component and rotatably mounted on each drive component. Each drive component is drive-connected to the conveying component. The drive component is fixedly mounted on the concrete foundation and drive-connected to at least one drive component. The drive component drives at least one drive component to rotate, and the drive component moves the conveying component, which then moves past the water storage tank.

[0008] Optionally, the drive component includes a rotating shaft, two sprockets, and two gantry frames. The two gantry frames are fixedly installed on a concrete foundation. The two ends of the rotating shaft are rotatably connected to the two gantry frames. The two sprockets are mounted on the rotating shaft and are fixedly connected to the rotating shaft. The drive component is connected to the rotating shaft for transmission and drives the rotating shaft to rotate.

[0009] Optionally, the conveying component includes a first chain, a second chain, and multiple molds. The first chain meshes with one sprocket in each of the driving components, and the second chain meshes with another sprocket in each of the driving components. The first chain and the second chain are arranged laterally. The two ends of the mold are fixedly installed on links on the first chain and the second chain, respectively, and the mold is perpendicular to the links on the first chain or the second chain. The mold has a casting cavity.

[0010] Optionally, each of the supporting components is installed on a concrete foundation. The initial cooling component includes multiple guide pipes, each of which is equipped with multiple nozzles, and the nozzles are connected to the guide pipes. The guide pipes are installed on the supporting components and are located below the mold. The outlet ends of the nozzles face the bottom wall or side wall of the mold.

[0011] Optionally, the support component includes two columns and at least one crossbeam. The lower ends of the two columns are fixedly installed to the concrete foundation, and the two ends of the crossbeam are fixedly connected to the upper middle part of the two columns. The guide pipe is fixedly installed on the two columns. Two support rods are fixedly installed on each column. The support rods are located below the first chain or the second chain, and the upper surface of the support rods abuts against the rollers on the links of the first chain or the second chain.

[0012] Optionally, a plurality of rollers are rotatably mounted embedded in the support rod, and the rollers abut against rollers on links of the first chain or the second chain.

[0013] Optionally, the primary cooling component also includes a water pump, which is installed on a concrete foundation. The inflow end of the water pump is located in a water storage tank, and the outflow end of the water pump is connected to each of the guide pipes.

[0014] (III) Beneficial Effects

[0015] This utility model provides a continuous casting device for a lead ingot casting machine, which has the following beneficial effects:

[0016] 1. This invention utilizes a primary cooling component to directly spray cold water onto the bottom or side walls of the mold, rapidly cooling the molten lead inside. Compared to existing technologies, this cooling method significantly improves cooling efficiency and shortens the solidification time of the molten lead, thereby increasing the production efficiency of lead ingots. Specifically, the primary cooling component includes multiple guide pipes and nozzles. The guide pipes are mounted on a support component below the mold, and the outlet ends of the nozzles face the bottom or side walls of the mold. A water pump delivers water from a storage tank to the guide pipes, which are then sprayed onto the mold through the nozzles, achieving rapid cooling of the molten lead. This cooling method is more efficient than traditional natural or air cooling, quickly reducing the temperature of the molten lead and allowing it to solidify faster. By improving cooling efficiency, not only can the production cycle be shortened, but the quality of the lead ingots can also be improved, reducing defects caused by excessively long cooling times.

[0017] 2. This utility model achieves continuous production of lead ingots through the continuous movement of the conveying components. Compared with existing technologies, this continuous production method can greatly improve production efficiency and reduce production time. Specifically, the conveying components adopt a chain structure with the ends connected, which can continuously transport the mold to the casting and cooling positions, and the mold's conveying movement position is more precise. The driving component drives the rotating shaft to rotate, which in turn drives the sprocket to rotate, thereby moving the conveying components. When the conveying components move past the water storage tank, the molten lead in the mold is cooled and solidified. Through this continuous production method, the problems of slow mold cooling and solidification speed and inability to continuously inject lead ingots in traditional equipment are avoided, achieving highly efficient production of lead ingots.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0030] Please see Figures 1 to 8 This utility model provides a technical solution: A continuous casting device for a lead ingot casting machine is implemented in conjunction with a holding furnace 7 (existing equipment, specific structure not described in detail). After the lead raw material is smelted in a melting furnace (such as a reverberatory furnace, induction furnace, etc.) to become molten lead, the molten lead is transferred and injected into the holding furnace 7 for settling. The molten lead is introduced into the ingot mold (lead ingot mold) through a chute 8 (i.e., a guide trough or pipe) on the holding furnace 7. The chute 8 is generally equipped with a gate or uses a metering pump (existing equipment, specific structure not described in detail) to control the flow rate of the molten lead (usually 5~10 L / min), ensuring continuous and stable flow into the ingot mold.

[0031] A continuous casting device for a lead ingot casting machine includes a drive component 1, a conveying component 4, a primary cooling component 5, multiple support components 6, four drive components 2, and a concrete foundation 9 made of concrete components.

[0032] The central and two end regions of the concrete foundation 9 are planar sections, with the edges of the end regions gradually sloping downwards towards the central region. A water storage tank 10 is formed above the central region of the concrete foundation 9. The water storage tank 10 is used to store cooling water.

[0033] All four drive components 2 are mounted on the concrete foundation 9. Two drive components 2 are fixedly mounted in the middle area of ​​the concrete foundation 9, and the other two drive components 2 are fixedly mounted at both ends of the concrete foundation 9. The function of the drive components 2 is to provide power to the conveying component 4, enabling it to move continuously; at the same time, the drive components 2 also support the conveying component 4.

[0034] The conveying component 4 is a chain structure with its ends connected. The conveying component 4 is mounted on each driving component 2, and is rotatably mounted on each driving component 2. Each driving component 2 is drive-connected to the conveying component 4. The driving component 1 is fixedly mounted on the concrete foundation 9 and is drive-connected to at least one driving component 2. The driving component 1 drives at least one driving component 2 to rotate, and the driving component 2 drives the conveying component 4 to move. The conveying component 4 moves through the water storage tank 10. The conveying component 4 includes multiple molds 401, each mold 401 having a casting cavity.

[0035] The conveying component 4 transports the mold 401 to the casting and cooling positions. The casting cavity on the mold 401 is used to hold molten lead. The driving component 2 drives the conveying component 4 to move, allowing the mold 401 to move to the casting position (below the location of the chute 8) and the cooling position (located at the water storage tank 10 and the primary cooling component 5). Molten lead poured from the chute 8 enters the mold 401, which holds and slowly moves the molten lead. When the mold 401 moves past the water storage tank 10, the height of the upper opening of the mold 401 is higher than the highest liquid level 3 in the water storage tank 10. Cooling water can reach the bottom wall and part of the side wall of the mold 401, but does not submerge the upper opening, preventing direct water ingress into the mold 401.

[0036] Specifically, the drive component 2 includes a rotating shaft 202, two sprockets 203, and two gantry frames 201. Both gantry frames 201 are fixedly mounted on the concrete foundation 9. The two ends of the rotating shaft 202 are rotatably connected to the two gantry frames 201. Both sprockets 203 are mounted on the rotating shaft 202, and the sprockets 203 are fixedly connected to the rotating shaft 202. The drive component 1 is connected to the rotating shaft 202 via a transmission mechanism, and the drive component 1 drives the rotating shaft 202 to rotate.

[0037] The conveying component 4 includes a first chain 402 and a second chain 403. The first chain 402 meshes with one sprocket 203 in each of the driving components 2, and the second chain 403 meshes with the other sprocket 203 in each of the driving components 2. The first chain 402 and the second chain 403 are arranged laterally. The two ends of the mold 401 are fixedly installed on the links of the first chain 402 and the second chain 403, respectively, and the mold 401 is perpendicular to the links of the first chain 402 or the second chain 403.

[0038] The drive component 1 includes, but is not limited to, motors and hydraulic drive systems (existing equipment will not be described in detail). The drive component 1 serves as the drive source, driving the rotating shaft 202 to rotate, thereby causing the rotating shaft 202 to drive the sprocket 203 to rotate. When the two sprockets 203 rotate synchronously, they drive the first chain 402 and the second chain 403 to move. The synchronous movement of the first chain 402 and the second chain 403 also drives the mold 401 to move, thus achieving the purpose of moving the conveying component 4.

[0039] More specifically, each support component 6 is mounted on a concrete foundation 9. The primary cooling component 5 includes multiple guide pipes 502, each guide pipe 502 having multiple nozzles 503 mounted on it, and the nozzles 503 communicating with the guide pipes 502. The guide pipes 502 are mounted on the support components 6, located below the mold 401, with the outlet ends of the nozzles 503 facing the bottom or side wall of the mold 401. The primary cooling component 5 also includes a water pump 501, mounted on the concrete foundation 9, with the inlet end of the water pump 501 located within a water storage tank 10, and the outlet end of the water pump 501 communicating with each guide pipe 502.

[0040] Water is pumped by pump 501 into guide pipe 502, and then sprayed onto mold 401 through nozzle 503 to achieve rapid cooling of molten lead. The primary cooling component 5 provides initial cooling to the molten lead in mold 401, accelerating solidification and allowing it to initially solidify before entering water storage tank 10. Pump 501 pumps water from water storage tank 10 into guide pipe 502, and then sprays it onto mold 401 through nozzle 503 to achieve rapid cooling of molten lead. The water sprayed from nozzle 503 is not a high-speed jet; the water flows out slowly, contacting the bottom or outer wall of mold 401 to achieve cooling. This also prevents water from splashing into mold 401 and impacting the molten lead inside, causing damage.

[0041] More specifically, the support component 6 includes two uprights 601 and at least one crossbeam 602. The lower ends of the two uprights 601 are fixedly installed to the concrete foundation 9, and the two ends of the crossbeam 602 are fixedly connected to the upper middle part of the two uprights 601. The guide pipe 502 is fixedly installed on the two uprights 601. Two support rods 603 are fixedly installed on each upright 601. The support rods 603 are located below the first chain 402 or the second chain 403, and the upper surface of the support rods 603 abuts against the rollers on the links of the first chain 402 or the second chain 403. More specifically, multiple rolling wheels 604 are rotatably mounted embedded in the support rods 603, and the rolling wheels 604 abut against the rollers on the links of the first chain 402 or the second chain 403.

[0042] The support rod 603 serves to support the conveying component 4, specifically supporting either the first chain 402 or the second chain 403. In this technical solution, the first chain 402 and the second chain 403 are under load. The molten lead has a certain weight before and after solidification, and the molten lead and mold 401 drag the first chain 402 and the second chain 403 downwards. The arrangement of each support component 6 prevents damage to the first chain 402 and the second chain 403 due to high pressure during long-term operation, effectively extending their service life. Furthermore, it reduces the energy consumption when driving the first chain 402 and the second chain 403. In other words, the support rod 603 functions similarly to a slide rail. The support rod 603 is made of wear-resistant, low-friction material to enhance wear resistance and reduce sliding resistance. Multiple rolling wheels 604 are rotatably mounted embedded in the support rod 603. These rolling wheels 604 abut against rollers on the links of the first chain 402 or the second chain 403. The function of the rolling wheels 604 is to further reduce friction during the movement of the conveying component 4, thereby improving its moving efficiency. The rolling wheels 604 are made of wear-resistant, low-friction material to enhance wear resistance and reduce sliding resistance.

[0043] In operation, the drive unit 1 rotates the drive shaft 202, which in turn drives the sprocket 203 to rotate, thereby moving the conveying component 4. The conveying component 4 transports the mold 401 to the casting position, and the molten lead is injected into the casting cavity of the mold 401 through the chute 8 (generally referring to the pipe for discharging molten lead, which is usually equipped with a metering valve, etc., which will not be described in detail here) of the holding furnace 7. After casting is completed, the conveying component 4 moves the mold 401 to a new position. During this process, the water pump 501 sprays cold water onto the mold 401 through the nozzle 503 to initially cool the molten lead inside the mold 401. The cooled lead ingot is then removed from the mold 401, completing one production cycle. This continuous production method greatly improves the production efficiency of lead ingots, while also improving cooling efficiency, shortening the production cycle, and improving the quality of the lead ingots.

[0044] refer to Figure 5 In actual implementation, the conveying component 4 has a horizontal conveying section at a certain distance near the end of the holding furnace 7. The mold 401 moves relatively smoothly horizontally in this section, and the molten lead in the mold 401 is also horizontal. Under these conditions, the mold 401 receives initial cooling and shaping from the initial cooling component 5. After shaping, it is tilted into the water storage tank 10 for secondary complete cooling, thus preventing spillage caused by the tilt. Due to drawing limitations... Figure 5The horizontal conveying section of the conveying component 4 near the end of the holding furnace 7 is not shown. When there is a horizontal conveying section of a certain distance near the end of the holding furnace 7, there may be more than four drive components 2, such as five or more, and the number is not limited.
