Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for metal smelting, and in particular to a mobile slag removal system. Background Technology

[0002] In the copper smelting industry, the water quenching process involves using water to cool molten copper. As the copper solidifies, it bursts into fine copper slag, known as matte. This slag is scattered in the quenching tank, requiring a slag-collecting machine to remove it for the next smelting step. Current technology typically uses an inclined chain bucket conveyor, with one end extending into the quenching tank and the other outside. During operation, a drive motor (mounted at the higher end of the conveyor) pulls the chain buckets to scoop up the matte. Small holes in the buckets allow liquid to flow back into the quenching tank. As the motor continues, the matte is transported outside the tank and unloaded at the higher end of the conveyor. After operation, the lower end of the conveyor remains submerged, which, prolonged immersion can cause it to rust, affecting subsequent operation. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a mobile slag removal system that solves the problem that the chain bucket conveyor is prone to rusting when one end is submerged in the water quenching tank.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mobile slag removal system includes a mounting frame with an inclined guide rail fixed on it. The higher end of the guide rail extends above the mounting frame, and the lower end extends below it. A chain bucket conveyor is movable along the guide rail in its inclined direction. A material guide chute is fixed at the higher end of the guide rail. The material guide chute is inclined along the guide rail and has a material guide outlet at a lower position. A material guide hopper is also fixed on the mounting frame and communicates with the material guide outlet. A slag guide pipe is also fixed at the lower end of the material guide hopper and communicates with it. A liquid guide hopper is also fixed to the slag guide pipe. A filter plate is inclinedly fixed between the liquid guide hopper and the slag guide pipe. The filter plate is provided with a plurality of filter holes. The lower end of the two guide rails extends into the water quenching tank. When slag removal is not required, the chain bucket conveyor is completely above the water quenching tank and does not come into contact with the water. When slag removal is required, it descends into the water quenching tank and returns to the top of the water quenching tank after slag removal is completed. This avoids the chain bucket conveyor from being in contact with water for a long time and solves the problem that the chain bucket conveyor with one end submerged in the water quenching tank in the existing technology is prone to rust.

[0006] Furthermore, an installation platform is fixed to the top of the installation frame, and a winch is fixedly installed on the installation platform. The winch is connected to a pair of winch drums, and each winch drum is wound with a cable. One end of each cable is fixed to a chain bucket conveyor.

[0007] Furthermore, two guide wheel sets are also installed on the installation platform. The ends of the two cables away from the chain bucket conveyor are respectively fixed with counterweights after passing through a guide wheel set, and the middle section of the cables is wound on the winch drum.

[0008] Furthermore, two pairs of vertically extending sliding guide posts are fixed on the mounting frame, and two counterweights are slidably positioned between one pair of sliding guide posts.

[0009] Furthermore, the guide rail includes a pair, and multiple first rollers are installed on both sides of the chain bucket conveyor, with all the first rollers on the same side rolling in cooperation with a guide rail.

[0010] Furthermore, connecting blocks are fixed on both sides of the lower end of the chain bucket conveyor, and the cable is fixed to one of the connecting blocks.

[0011] Furthermore, the mounting frame is also equipped with two guide rollers located on both sides of the chain bucket conveyor, and the cable is connected to the connecting block after passing through the guide rollers.

[0012] Furthermore, the higher end of the guide rail is located above the mounting frame, and the lower end is located below the mounting frame.

[0013] Furthermore, it also includes a liquid receiving tank located between the mounting frame and the lower end of the guide rail.

[0014] Furthermore, the winch drum is designed to rotate and has a spiral groove recessed on its surface, into which the cable portion is accommodated.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting up a moving track, the chain bucket conveyor can be positioned entirely above the water quenching tank when slag removal is not required, without contact with water. When slag removal is needed, the lower end will descend into the water quenching tank for slag removal. After the slag removal is completed, it will return to the top of the water quenching tank. This avoids the chain bucket conveyor from being in contact with water for a long time and solves the problem that the chain bucket conveyor is prone to rust when one end is submerged in the water quenching tank in the existing technology.

[0017] During slag removal, the matte leaves from the higher end of the chain bucket conveyor, then falls into the guide hopper and enters the slag guide pipe. After passing through the filter plate, it is discharged from the slag guide pipe. At the filter plate, most of the mixed water can pass through the filter plate and into the liquid guide hopper, thus reducing the amount of water in the removed matte and facilitating subsequent processing.

[0025] The present invention will be further described in detail below through specific embodiments:

[0026] like Figure 1-4As shown, this solution provides a mobile slag removal system, which, like the prior art, includes a chain bucket conveyor 1. The difference lies in that it also includes an installation frame 3 fixed beside a water quenching tank 2. An installation platform 4 is fixed to the top of the installation frame 3, and a pair of inclined guide rails 5 are also fixed to the installation frame 3. The lower ends of the two guide rails 5 extend into the water quenching tank 2, and the higher ends of the guide rails 5 are higher than the installation platform 4. Support columns 6 are also fixed to the installation platform 4 to support the higher ends of the two guide rails 5. A guide chute 7 is fixed between the two guide rails 5. The guide chute 7 is also inclined, with its higher end fixed to the higher ends of the two guide rails 5, and its lower end close to and located on the installation platform 4. On the installation platform 4, a guide hopper 8 is fixedly mounted. A guide outlet is located at the lower end of the guide trough 7 and connects to the upper end of the guide hopper 8. The lower end of the guide hopper 8 extends downwards and is connected to a slag guide pipe 9. The slag guide pipe 9 extends obliquely downwards and a liquid guide hopper 10 is fixed below its middle section. A filter plate 11 is fixed between the liquid guide hopper 10 and the slag guide pipe 9, and the filter plate 11 has several filter holes 12. Furthermore, multiple pairs of first rollers 13 are installed on both sides of the chain bucket conveyor 1 along its length. These first rollers 13 cooperate with two guide rails 5 to allow the chain bucket conveyor 1 to move on the two guide rails 5. Additionally, a drive chain is also installed on the installation platform 4. The bucket conveyor 1 consists of a winch 14 that moves vertically and two pairs of first mounting seats 15. A winch drum 16 is rotatably mounted between each pair of first mounting seats 15. The output end of the winch 14 is connected to a reducer 17, which has two output ends connected to the two winch drums 16 respectively. When the winch 14 is running, it drives the two winch drums 16 to rotate synchronously. A cable 18 is wound around each of the two winch drums 16. Specifically, the middle section of the cable 18 has a multi-turn spiral structure wound around the winch drum 16. One end extends downwards and is fixed to one side of the bucket conveyor 1, while the other end is connected to a counterweight block 19 that slides vertically relative to the mounting frame 3. Thus, when the winch 14 is running… When the winch drum 16 rotates forward / reverse, the corresponding counterweight 19 moves up and down, and the other end of the cable 18 lowers / raises the chain bucket conveyor 1. This realizes the movement drive of the chain bucket conveyor 1 by the winch 14. Throughout the process, the winch drum 16 is wound with multiple turns of cable 18. This setting allows the chain bucket conveyor 1 to be completely above the water quenching tank 2 when slag removal is not required, without contact with water. When slag removal is required, the lower end moves down into the water quenching tank 2 for slag removal. After the slag removal is completed, it returns to the top of the water quenching tank 2. This avoids the chain bucket conveyor 1 from being in contact with water for a long time and solves the problem of rusting caused by one end of the chain bucket conveyor 1 being submerged in the water quenching tank 2 in the prior art.During slag removal, the matte exits from the higher end of the chain conveyor 1, then falls into the guide hopper 8 and enters the slag guide pipe 9. After passing through the filter plate 11, it is discharged from the slag guide pipe 9. At the filter plate 11, most of the mixed water can pass through the filter plate 11 and into the liquid guide hopper 10, thus reducing the water content in the removed matte and facilitating subsequent processing.

[0027] like Figure 1-4 As shown, in a more detailed scheme, the mounting platform 4 is also equipped with two guide wheel groups. The cable 18 passes through one of the guide wheel groups and then connects to a corresponding counterweight 19. Furthermore, two pairs of vertically extending sliding guide posts 20 are fixed on the mounting frame 3. They can be located on both sides of the mounting frame 3 or on the same side of the mounting frame 3. The two sides of the two counterweights 19 are respectively slidably engaged with one of the pairs of sliding guide posts 20. In this way, the sliding guide posts 20 provide a sliding foundation and vertical guidance for the counterweights 19, ensuring the stability of the counterweights 19 during operation. Furthermore, when the chain bucket conveyor 1 is at its highest position, the counterweights 19 are at their lowest position, so that the chain bucket conveyor 1 can be stably positioned at a higher position on the mounting frame 3.

[0028] like Figure 1-4 As shown, furthermore, a guide roller 21 is installed on each side of the higher end of the chain bucket conveyor 1. The two cables 18 are connected to the chain bucket conveyor 1 after passing through a guide roller 21 (the roller surface of the guide roller 21 has a groove for the cables 18 to be fully accommodated, so that the cables 18 do not detach from the guide roller 21). In detail, a connecting block 22 is fixed on each side of the lower end of the chain bucket conveyor 1. The cables 18 are fixed to the corresponding connecting block 22 after passing through the guide roller 21. In this way, when the winch 14 is running, the pulling force point is located on both sides of the lower end of the chain bucket conveyor 1, making the pulling smoother and the downward lowering process also smoother.

[0029] like Figure 1-4As shown, the winch drums 16 are positioned opposite each other on the mounting platform 4, meaning their axes coincide, and the length of the cable 18 wound on the two winch drums 16 (i.e., the length of the spiral portion) is also the same. Furthermore, continuous spiral grooves are recessed on the surfaces of the two winch drums 16, and the portion of the cable 18 wound on the winch drums 16 is incorporated into the grooves, thus providing winding guidance for the cable 18 and preventing significant lateral displacement of the cable 18 on the winch drums 16 during the winching process. Furthermore, the ends of the two cables 18 facing the guide rollers 21 are opposite to each other on the two winch drums 16, while the ends facing the guide wheel assembly are close to each other. When the chain bucket conveyor 1 is at its lowest position, the ends of the two cables 18 facing the guide wheel assembly are closest to each other, and at this time, there are empty grooves on the winch drums 16 for subsequent cables 18 to be wound in, so that the chain bucket conveyor 1 can smoothly reach the highest position.

[0030] like Figure 1-4 As shown in the detailed scheme, a guide wheel assembly includes a second mounting base 23 and a third mounting base 24 fixed on the mounting platform 4. The second mounting base 23 and the third mounting base 24 are respectively equipped with a first guide wheel 25 and a second guide wheel 26. The cable 18 changes direction by 90° horizontally after passing through the first guide wheel 25, and then changes direction by 90° vertically after passing through the second guide wheel 26. Finally, it is fixedly connected to the corresponding counterweight 19.

[0031] like Figure 1-4 As shown in the detailed scheme, two pairs of sliding guide posts 20 are fixed on both sides of the mounting frame 3 and located on both sides of the chain bucket conveyor 1. Each pair of sliding guide posts 20 has a vertically extending groove 27 recessed on its adjacent side. Multiple second rollers 28 that roll in cooperation with the grooves 27 are installed on both sides of the counterweight 19. This ensures greater stability during the up-and-down movement of the counterweight 19. More specifically, the second rollers 28 are installed via a connecting shaft, specifically fixed to the side wall of the counterweight 19. The second rollers 28 are rotatably mounted on the connecting shaft. The inner walls of the second roller 28 and the groove 27 roll in contact to further improve stability. The first roller 13 is also connected to the side of the chain bucket conveyor 1 via a connecting shaft. The difference is that the first roller 13 and the corresponding guide rail 5 roll in contact up and down. This can distribute the heavy pressure of the chain bucket conveyor 1 onto the guide rail 5. In a more detailed design, the inner edge of the first roller 13 (the side closer to the chain bucket conveyor 1) also protrudes outward with a limiting part. The limiting part slides in contact with the guide rail 5, which can increase the stability between the first roller 13 and the guide rail 5.

[0032] like Figure 1-4As shown in the detailed scheme, when the chain bucket conveyor 1 is at its lowest position, its highest point (i.e., the discharge end) is located directly above or higher than the inlet of the guide hopper 8. This allows the matte conveyed by the chain bucket conveyor 1 to fall directly into or, after passing through the guide chute 7, into the guide hopper 8. Furthermore, the slag guide pipe 9 is inclined, with a vertically downward-extending discharge pipe fixed at its lower end, below which a receiving cart or other container can be placed. The liquid guide hopper 10 is fixed below the higher end of the slag guide pipe 9, and a filter plate 11 is positioned between them. This filter plate 11 has several filter holes 12. After the matte enters the slag guide pipe 9 through the guide hopper 8, it will then pass obliquely downwards through the filter plate 11. The water can pass through the filter holes 12, while the matte flows smoothly downwards into the discharge pipe and is finally discharged. In a further embodiment, the filter plate 11 is also fixed with several inclined horizontal bars 30 extending from top to bottom. The inclined horizontal bars 30 extend laterally and are inclined in the same direction as the filter plate 11. The filter holes 12 include the part set between the inclined horizontal bars 30 and the part set on the inclined horizontal bars 30. That is, there is an inclined surface on the inclined horizontal bar 30, and there is an acute angle between the inclined surface and the filter plate 11. The filter holes 12 are also set on the inclined surface. When the matte flows downwards, the inclined surface can slow down the matte, making it easier for the water to pass through the filter holes 12, thereby reducing the amount of water in the matte.

[0033] like Figure 1 As shown, a liquid receiving tank 29 is also provided between the mounting frame 3 and the lower end of the guide rail 5, so that the water flowing out during the operation of the chain bucket conveyor 1 can also be collected in the liquid receiving tank 29 below, preventing it from spilling onto the surrounding ground.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
