Description

Technical Field

[0001] The invention relates to the technical field of smelting furnace processing, in particular to a sulphur-arsenic slag vortex smelting furnace. Background Art

[0002] The vortex smelting furnace is a highly efficient metal smelting equipment. The centrifugal force generated by high-speed rotation makes the metal material flow in a vortex in the furnace, thereby increasing the contact area between the material and the heat source and improving the smelting efficiency. The vortex smelting furnace is widely used in the smelting of non-ferrous metals, such as copper, aluminum, zinc, etc., and has significant advantages in the metallurgical industry due to its environmental protection characteristics.

[0003] Compared with the existing rotary kiln calcified slag, the vortex furnace method can comprehensively recover valuable metals such as Re, Cu, Pb, Sn, etc. in sulfur and arsenic, and make the As and sulfur in it resource-based. Existing smelting furnaces usually use manual feeding in the charging method. The feeding usually adds a batch of materials to the smelting furnace intermittently, which can make the materials smelted more fully. However, when manually feeding, whether it is the time of intermittent feeding or dividing a batch of materials into multiple groups, the uniformity of each group of materials cannot be well controlled. This results in the smelting furnace being unable to well control the timing and quantity of adding materials, affecting the smelting effect of the materials. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a sulfur-arsenic slag vortex smelting furnace to solve the technical problem that the intermittent unloading time of each batch of smelting materials and the uniformity of each batch of material grouping in the above-mentioned background technology cannot be well controlled.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sulfur-arsenic slag vortex smelting furnace, comprising a tank body and a smelting chamber arranged inside the tank body for smelting materials, a storage assembly for storing a batch of materials is arranged inside the tank body, a feeding assembly for evenly grouping a batch of materials is arranged below the storage assembly, a driving assembly for driving the feeding assembly to transport materials into the smelting chamber is arranged on the storage assembly, and a unloading assembly for separating the slag discharged from the smelting chamber from the solution is arranged below the smelting chamber.

[0006] Preferably, the material storage assembly comprises a material storage hopper, the material storage hopper is fixedly installed inside the tank body, the material storage hopper is in a cone shape, a material discharge port is provided below the material storage hopper, and a control valve is provided on the material discharge port.

[0007] Preferably, the feeding assembly comprises a supporting turntable, which is rotatably connected to the inside of the tank body, and the supporting turntable is provided with distribution hoppers in a circular array, and each of the distribution hoppers is of the same size.

[0008] Preferably, each of the material distribution hoppers is provided with a telescopic plate and a telescopic sleeve rod, the telescopic sleeve rod is sleeved with an arc spring, the telescopic plate and the telescopic sleeve rod are connected by a push block, a control board is provided inside the tank body, and the push block is inserted into a guide groove opened on the control board.

[0009] Preferably, the driving assembly comprises a motor, the motor is arranged inside the tank body, a rotating shaft is fixedly mounted on the output end of the motor, the rotating shaft is rotatably connected inside the tank body, and one end of the rotating shaft away from the motor is connected to the supporting turntable.

[0010] Preferably, a valve stem is provided on the control valve, and a pulley set is sleeved between the rotating shaft and the valve stem.

[0011] Preferably, the driving assembly also includes a rotating rod, which is rotatably connected inside the tank body and fixedly installed on the side of the supporting turntable away from the rotating axis. A first threaded rod is rotatably connected inside the tank body, and a bevel gear set is arranged between the rotating rod and the first threaded rod.

[0012] Preferably, a limiting rod is provided inside the tank body, and support springs are sleeved on the first threaded rod and the limiting rod.

[0013] Preferably, the material discharge assembly comprises a first screen and a second screen, the first screen and the second screen are rotatably connected, and the second screen is threadedly sleeved on the second threaded rod.

[0014] Preferably, one side of the first screen is threadedly sleeved on the first threaded rod, and the side of the first screen away from the first threaded rod is slidably connected to the limiting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: a batch of materials is transported into the interior of a storage component, the storage component will transport the materials evenly in batches into multiple storage hoppers, the driving component drives the storage component to rotate, and the storage component will transport the materials in a storage hopper into the smelting chamber for smelting at intervals. By controlling the rotation speed of the storage component and the size of each storage hopper chamber, a batch of materials can be evenly divided into multiple groups, and then the gaps are controlled to transport them into the smelting chamber in sequence, which can ensure that the materials can be efficiently and fully smelted.

[0016] When a batch of materials enters the smelting chamber for smelting, the slag and solution produced after smelting are discharged from the smelting chamber to the top of the unloading component. The unloading component not only separates the slag and the solution, but also produces slag above the unloading component. At this time, the control valve of the storage component is closed, and the material inside the storage component cannot enter the feeding component. Only after the slag above the unloading component is disposed of, the control valve can be automatically opened to smelt the next batch of materials. In this way, it can be prevented that the slag of the previous batch of materials has not been collected yet, and the next batch of materials has started to be smelted and slag has been produced, resulting in the slag of the two batches of materials mixing together, affecting the collection of valuable metals inside the slag of different materials.

[0025] See also Figure 1-Figure 6 The present invention provides a technical solution: a sulfur-arsenic slag vortex smelting furnace, comprising a tank body 1 and a smelting chamber 5 arranged inside the tank body 1 for smelting materials, a storage component 2 for storing a batch of materials is arranged inside the tank body 1, a feeding component 3 for evenly grouping a batch of materials is arranged below the storage component 2, a driving component 4 for driving the feeding component 3 to transport the material into the smelting chamber 5 is arranged on the storage component 2, and a discharge component 6 for separating the slag discharged from the smelting chamber 5 from the solution is arranged below the smelting chamber 5.

[0026] The specific working process of the present invention is as follows: a batch of materials are transported into the interior of the storage component 2, and the driving component 4 is started at the same time. The driving component 4 drives the feeding component 3 to rotate, and the feeding component 3 evenly divides a batch of materials in the storage component 2 into multiple groups and intermittently feeds them into the interior of the smelting chamber 5. The smelting chamber 5 performs vortex smelting, and multiple groups of materials are fully smelted in the smelting chamber 5. The slag produced by the smelting is transported to the top of the unloading component 6 through the smelting chamber 5. As the slag is continuously transported to the top of the unloading component 6, the unloading component 6 closes the storage component 2. At this time, the storage component 2 cannot transport the material into the feeding component 3, and the unloading component 6 separates the slag and the solution. After the slag on the unloading component 6 is cleaned, the opening of the storage component 2 is reopened.

[0027] Please refer to Figure 5 The material storage assembly 2 includes a material storage hopper 21, which is fixedly installed inside the tank body 1. The material storage hopper 21 is conical in shape, and a material discharge port 22 is provided below the material storage hopper 21. A control valve 23 is provided on the material discharge port 22.

[0028] A batch of materials is conveyed into the storage hopper 21, which is arranged in a cone shape. The materials are conveyed along the inside of the storage hopper 21 to the discharge port 22, and the materials are discharged through the discharge port 22. The control valve 23 is used to control the discharge port 22 to be opened or closed.

[0029] Please refer to Figure 2-Figure 5 The feeding assembly 3 includes a supporting turntable 31, which is rotatably connected to the inside of the tank body 1. The supporting turntable 31 is provided with dividing hoppers 32 in a circular array, and each dividing hopper 32 is of the same size. Each dividing hopper 32 is provided with a telescopic plate 33 and a telescopic sleeve rod 34, and the telescopic sleeve rod 34 is sleeved with an arc spring 36. The telescopic plate 33 and the telescopic sleeve rod 34 are connected by a push block 35. A control board 37 is provided inside the tank body 1, and the push block 35 is inserted into a guide groove provided on the control board 37.

[0030] When the push block 35 moves to the stopper, the support turntable 31 continues to rotate, and the stopper will push the push block 35 backward first, and the stopper will push the telescopic plate 33 and the telescopic sleeve rod 34 to move backward. At this time, the upper opening of the distribution hopper 32 will be opened. At this time, the material can be transported into the distribution hopper 32, or the material in the distribution hopper 32 can be discharged. When the telescopic plate 33 and the telescopic sleeve rod 34 are in the most contracted state, the support turntable 31 continues to rotate, and the push block 35 cannot move backward. The push block 35 will be deformed and staggered. The stopper, at this time, the push block 35 rebounds and resets under the action of the arc spring 36, and the push block 35 drives the telescopic plate 33 and the telescopic sleeve rod 34 to rebound and reset, and the telescopic plate 33 closes the upper opening of the distribution hopper 32 again.

[0031] Please refer to Figure 2-Figure 5 The drive assembly 4 includes a motor 41, which is arranged inside the tank body 1. A rotating shaft 42 is fixedly installed at the output end of the motor 41. The rotating shaft 42 is rotatably connected to the inside of the tank body 1. The end of the rotating shaft 42 away from the motor 41 is connected to the support turntable 31. A valve stem is arranged on the control valve 23. A pulley set 43 is sleeved between the rotating shaft 42 and the valve stem. The drive assembly 4 also includes a rotating rod 44, which is rotatably connected to the inside of the tank body 1. The rotating rod 44 is fixedly installed on the side of the support turntable 31 away from the rotating shaft 42. The inside of the tank body 1 is rotatably connected There is a first threaded rod 46, a bevel gear set 45 is arranged between the rotating rod 44 and the first threaded rod 46, a limiting rod 47 is arranged inside the tank body 1, and support springs 48 are sleeved on the first threaded rod 46 and the limiting rod 47. The unloading assembly 6 includes a first screen 61 and a second screen 62, the first screen 61 and the second screen 62 are rotatably connected, the second screen 62 is threadedly sleeved on the second threaded rod 63, one side of the first screen 61 is threadedly sleeved on the first threaded rod 46, and the first screen 61 is slidably connected to the limiting rod 47 on the side away from the first threaded rod 46.

[0032] The motor 41 is started, and the motor 41 drives the rotating shaft 42 to rotate forward, and the rotating shaft 42 drives the supporting turntable 31 to rotate forward, and the rotating shaft 42 drives the valve stem to rotate forward through the pulley group 43. When the motor 41 rotates one circle, all the materials in the feeding assembly 3 are transported into the smelting chamber 5, and the motor 41 continues to rotate until the valve stem rotates forward to close the control valve 23. The supporting turntable 31 rotates forward and also drives the rotating rod 44 to rotate, and the rotating rod 44 drives the bevel gear group 45 to rotate, and the bevel gear group 45 drives the first threaded rod 46 to rotate, and the first screen 61 is provided with a threaded hole matched with the first threaded rod 46, and the first screen 61 begins to descend; After all the materials in the feeding assembly 3 are transported into the smelting chamber 5, the motor 41 is turned off. At this time, the slag of the first screen 61 is transported to the top of the first screen 61. At this time, the slag continues to press the screen into a descending state through gravity, and when the screen is in the initial rising state, the holes between the first screen 61 and the second screen 62 are staggered, and the first screen 61 and the second screen 62 block the holes between each other. At this time, the solution cannot pass through the first screen 61 and the second screen 62. As the first screen 61 and the second screen 62 descend, a threaded hole compatible with the second threaded rod 63 is opened in the second screen 62. The second screen 62 descends and is driven by the second threaded rod 63 to rotate. The first screen 61 and the second threaded rod 63 have no connection relationship and are rotationally connected to the second screen 62, so the second screen 62 rotates the first screen 61 will not rotate, and the second screen 62 rotates to align the holes with the first screen 61. At this time, the solution can pass through the first screen 61 and the second screen 62 to be discharged. There is no connection between the second screen 62 and the first threaded rod 46. At this time, the support spring 48 is compressed by the second screen 62, and the motor 41 stops working. When the slag on the first screen 61 is collected, there is no weight of the slag, and the first screen 61 rises under the rebound force of the two support springs 48. At this time, the first screen 61 drives the first threaded rod 46 to reverse, and the first threaded rod 46 drives the valve stem to reverse through the component transmission. When the first screen 61 and the second screen 62 rise and reset, the valve stem rotates to open the control valve 23. When the control valve 23 is opened, the motor 41 is energized, and the motor 41 rotates forward to drive the feeding component 3 to convey materials.
