Description

Technical Field

[0001] This utility model relates to the field of antimony slag lead separation technology, and in particular to a pyrometallurgical antimony slag lead separation device. Background Technology

[0002] The pyrometallurgical antimony slag lead separation device is a complete set of technical equipment systems specifically applied to the subsequent solid waste treatment stage of the pyrometallurgical antimony smelting industry. Its core function is to achieve efficient separation, enrichment and recovery of lead from the "antimony slag" (mainly composed of antimony oxides, silicates, incompletely recovered antimony metal and associated lead compounds) generated during the pyrometallurgical antimony smelting process through physical or chemical-physical coupled process methods. Ultimately, it achieves the solid waste treatment goals of "reduction (reducing the harm of waste residue), resource recovery (recovering valuable metals such as lead), and harmlessness (reducing the environmental risk of waste residue)".

[0003] In the pyrometallurgical antimony smelting process, the separation of antimony slag from lead liquid is a crucial step in recovering lead resources and improving the utilization rate of antimony slag. However, traditional slag-lead separation processes and equipment have many technical drawbacks. Traditional equipment often directly feeds the slag into the separation chamber without a guiding and buffering structure. The slag is prone to splashing and stratification of lead liquid inside the chamber due to excessive impact force. At the same time, the initial separation effect of coarse antimony slag and lead liquid is poor, and some coarse slag can easily enter subsequent stages with the lead liquid, increasing the burden of subsequent processing. In the lead liquid purification stage, traditional equipment mostly relies on static settling, which easily forms a fine slag coating on the surface of the lead liquid, hindering the settling of fine slag. The traditional pyrometallurgical antimony slag lead separation device suffers from poor purification results due to temperature fluctuations. Furthermore, without a stable temperature control structure, the lead liquid is prone to solidification due to temperature fluctuations, causing equipment blockage and affecting production continuity. In addition, the cooling process of the purified lead liquid relies heavily on traditional methods such as natural cooling or simple air cooling, resulting in low cooling efficiency and difficulty in accurately controlling the temperature of the cooled lead liquid, which is detrimental to subsequent lead liquid processing steps. These problems collectively lead to low separation efficiency, low lead recovery rate, and poor operational convenience in traditional pyrometallurgical antimony slag lead separation devices, making them unsuitable for large-scale industrial production. Therefore, we propose a pyrometallurgical antimony slag lead separation device. Utility Model Content

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention solves the problem that separating antimony slag from molten lead is a crucial step in recovering lead resources and improving the utilization rate of antimony slag during pyrometallurgical antimony production. However, traditional slag-lead separation processes and devices suffer from numerous technical drawbacks. Traditional devices often directly feed the slag into the separation chamber without a guiding and buffering structure. Excessive impact force from the slag can cause molten lead to splash and stratify within the chamber. Furthermore, the initial separation of coarse antimony slag from molten lead is poor, with some coarse slag easily entering subsequent stages with the molten lead, increasing the burden on subsequent processing. In the lead purification stage, traditional devices often rely on static settling. Fine slag coatings easily form on the surface of molten lead, hindering slag settling and resulting in poor purification. Furthermore, without a stable temperature control structure, molten lead is prone to solidification due to temperature fluctuations, causing equipment blockage and affecting production continuity. In the cooling process after purification, traditional methods mostly rely on natural cooling or simple air cooling, which are inefficient and difficult to precisely control the temperature of the cooled molten lead, hindering subsequent lead processing steps. These problems collectively lead to low separation efficiency, low lead recovery rate, and poor operational convenience in traditional pyrometallurgical antimony slag lead separation devices, making them unsuitable for large-scale industrial production.

The mounting plate is located below the bottom end of the second guide plate. A stirring assembly is disposed within a fixed box and is used to stir the molten lead.

A servo motor is fixedly installed on the outer wall of the box, and one end of the output shaft of the servo motor passes through the outer wall of the box and is fixedly connected to one end of the stirring auger.

[0008] Preferably, two fixing blocks are fixedly installed on one side of the top surface of the first filter plate, and the same guide plate is fixedly installed between the two fixing blocks. A feed pipe is fixedly installed on the top surface of the box, the bottom end of the feed pipe penetrates the top surface of the box and extends into the interior, and the bottom end of the feed pipe is fixedly connected to the top of the guide plate.

[0009] Preferably, the outer side wall of the second filter plate is fixedly connected to the inner side wall of the housing, and a first guide plate is fixedly installed on the top surface of the second filter plate, the first guide plate being located between the first filter plate and the second filter plate.

[0010] Preferably, the top surface of the mounting plate is provided with a flow guide groove, the flow guide groove is located below the bottom end of the second flow guide inclined plate, and one side of the flow guide groove is connected to the inside side of the fixing box.

[0011] Preferably, a guide tube is fixedly installed inside the mounting box. One end of the guide tube passes through one side of the interior of the mounting box and is connected to the other side of the interior of the fixed box. The other end of the guide tube passes through the inner wall of the mounting box and extends to the outside. A discharge pipe is fixedly installed at the other end of the guide tube, and a valve is fixedly installed on the outer wall of the discharge pipe.

[0012] Preferably, the outer wall of the housing is provided with an opening groove, the opening groove is located on one side of the first filter plate, a rotating baffle is rotatably installed in the opening groove, a sleeve is fixedly installed on one side of the rotating baffle, a limiting hole is provided at the position opposite to the sleeve in the housing, and the same insert rod is movably connected between the sleeve and the limiting hole.

[0013] Beneficial effects 1. First, the worker feeds the pyrometallurgical antimony slag to be separated into the device through the feed pipe on the top of the box. The bottom end of the feed pipe precisely connects with the guide plate on the top surface of the first filter plate. Guided by the guide plate, the slag falls smoothly onto the surface of the first filter plate. The first filter plate intercepts coarse antimony slag particles. The lead liquid after preliminary filtration falls through the pores of the first filter plate and onto the second filter plate below, which is also fixed to the inner wall of the box. The first guide plate on the top surface of the second filter plate guides the lead liquid to be evenly distributed, further filtering out fine slag, completing the secondary filtration. The lead liquid after secondary filtration slides down the second guide plate fixed by two mounting blocks on the bottom surface of the second filter plate. The liquid lead falls onto the mounting plate, where a guide channel on the top surface directs it into a fixed box on one side of the bottom of the enclosure. Inside the fixed box, the liquid lead is further purified by an agitator. The core of this agitator is a stirring auger made of a high-temperature resistant alloy, capable of withstanding the high temperatures during the liquid lead separation process and preventing corrosion or deformation. The stirring auger is driven to rotate by a servo motor on the outer wall of the enclosure. During rotation, it breaks down the fine slag coating on the surface of the liquid lead, causing it to settle. Simultaneously, multiple heating tubes evenly distributed around the stirring auger on the inner wall of the fixed box continuously maintain a suitable temperature for the liquid lead to flow, preventing solidification and blockage.

[0014] 2. The purified lead liquid, after being stirred and refined, enters the installation box through the connecting structure between the fixed box and the installation box. The installation box is lined with coolant, which conducts temperature to the surface of the guide pipe, rapidly cooling the lead liquid to the temperature requirements for subsequent processing. The operator can control the valve on the outer wall of the discharge pipe to achieve quantitative discharge of the purified lead liquid. The coarse antimony slag accumulated on the first filter plate can be cleaned by opening the rotating baffle in the opening groove on the outer wall of the box and pulling out the insert rod in the limiting hole of the box, thus completing the entire slag-lead separation process.

[0018] Example 1: Please see Figure 1 - Figure 7 As shown in the figure, this embodiment provides a lead separation device for antimony slag from pyrometallurgical processes.

[0019] include: The housing 1 contains a first filter plate 6, the outer side wall of which is fixedly connected to the inner side wall of the housing 1. A second filter plate 9 is positioned below the first filter plate 6, and two mounting blocks 11 are fixedly installed on the bottom surface of the second filter plate 9. A second guide plate 12 is fixedly installed between the two mounting blocks 11. A fixing box 13 is fixedly installed on one side of the inner bottom surface of the housing 1. A mounting box 14 is positioned on one side of the fixing box 13, and its bottom surface is fixedly connected to the inner bottom surface of the housing 1. A mounting plate 15 is fixedly installed on the top surface of the mounting box 14, located below the bottom end of the second guide plate 12. An agitator assembly is also included. Inside the fixed box 13, used for agitating the molten lead, the worker first feeds the pyrometallurgical antimony slag to be separated into the device through the feed pipe 2 on the top surface of the box 1. The bottom end of the feed pipe 2 precisely connects with the guide plate 7 on the top surface of the first filter plate 6. Guided by the guide plate 7, the slag falls steadily onto the surface of the first filter plate 6, which can first intercept coarse antimony slag particles. The molten lead after preliminary filtration falls through the pores of the first filter plate 6 and onto the second filter plate 9, which is also fixed to the inner side wall of the box 1. The first guide plate 10 on the top surface of the second filter plate 9 guides the molten lead to be evenly distributed, further filtering fine slag and completing the secondary filtration. The molten lead after secondary filtration flows down the two mounting blocks 1 on the bottom surface of the second filter plate 9. The fixed second guide plate 12 slides down and finally falls onto the mounting plate 15. The guide groove 16 on the top surface of the mounting plate 15 guides the lead liquid into the fixed box 13 on one side of the bottom surface inside the tank 1. The lead liquid entering the fixed box 13 will be further purified by the stirring component. The core of the stirring component is the stirring auger 17, which is made of high-temperature resistant alloy and can withstand the high temperature environment during the lead liquid separation process, avoiding corrosion or deformation. It is driven to rotate by the servo motor 3 on the outer wall of the tank 1. During the rotation, it can break the fine slag coating layer remaining on the surface of the lead liquid and promote the sedimentation of the fine slag. At the same time, multiple heating tubes 18 evenly distributed on the inner wall of the fixed box 13 surround the stirring auger 17 to continuously maintain a suitable temperature for the lead liquid to flow. To prevent lead liquid from solidifying and clogging, the purified lead liquid, after being stirred and purified, enters the interior of the mounting box 14 through the connecting structure between the fixed box 13 and the mounting box 14. The mounting box 14 is lined with coolant, which conducts temperature to the surface of the guide pipe 20, rapidly cooling the lead liquid to meet the temperature requirements for subsequent processing. The operator can control the valve on the outer wall of the discharge pipe 21 to achieve quantitative discharge of the pure lead liquid. The coarse antimony slag accumulated on the first filter plate 6 can be cleaned by opening the rotating baffle 5 in the opening slot 4 on the outer wall of the box 1, pulling out the sleeve 22 and the insertion rod 19 in the limiting hole of the box 1, thus completing the entire slag-lead separation process.

One end of the output shaft of the servo motor 3 passes through the outer wall of the box 1 and is fixedly connected to one end of the stirring auger 17. The core of this agitation component is the stirring auger 17, which is made of high-temperature resistant alloy and can withstand the high-temperature environment during the lead liquid separation process, avoiding corrosion or deformation. It is driven to rotate by the servo motor 3 on the outer wall of the box 1.

The multiple heating tubes 18 evenly distributed on the inner wall of the fixed box 13 surround the agitator 17, continuously maintaining a suitable temperature for the flow of lead liquid and preventing the lead liquid from solidifying and blocking.

[0024] Example 4: This embodiment provides a pyrometallurgical antimony slag lead separation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] Two fixing blocks 8 are fixedly installed on one side of the top surface of the first filter plate 6. A guide plate 7 is fixedly installed between the two fixing blocks 8. A feed pipe 2 is fixedly installed on the top surface of the box 1. The bottom end of the feed pipe 2 penetrates the top surface of the box 1 and extends into the interior. The bottom end of the feed pipe 2 is fixedly connected to the top of the guide plate 7. The pyrometallurgical antimony slag to be separated first enters the device through the feed pipe 2 on the top surface of the box 1. The bottom end of the feed pipe 2 is precisely connected to the guide plate 7 on the top surface of the first filter plate 6. Under the guidance of the guide plate 7, the slag falls steadily onto the surface of the first filter plate 6, which can first intercept coarse antimony slag particles.

[0026] Example 5: This embodiment provides a pyrometallurgical antimony slag lead separation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0027] The outer wall of the second filter plate 9 is fixedly connected to the inner wall of the housing 1. A first guide plate 10 is fixedly installed on the top surface of the second filter plate 9. The first guide plate 10 is located between the first filter plate 6 and the second filter plate 9. The lead liquid after preliminary filtration falls through the holes of the first filter plate 6 and falls onto the second filter plate 9, which is also fixed to the inner wall of the housing 1. The first guide plate 10 on the top surface of the second filter plate 9 guides the lead liquid to be evenly distributed, further filtering fine residue and completing the secondary filtration.

[0028] Example 6: This embodiment provides a pyrometallurgical antimony slag lead separation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] The top surface of the mounting plate 15 is provided with a guide channel 16, which is located below the bottom end of the second guide inclined plate 12. One side of the guide channel 16 is connected to the inside side of the fixed box 13. After secondary filtration, the lead liquid will flow down the second guide inclined plate 12 and finally fall into the guide channel 16 on the top surface of the mounting plate 15. The guide channel 16 can play a good role in gathering and guiding the lead liquid, so that it flows smoothly to the inside side of the fixed box 13 connected to it, thereby completing the collection and subsequent processing of the lead liquid.

[0030] Example 7: This embodiment provides a pyrometallurgical antimony slag lead separation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] The installation box 14 is equipped with a guide pipe 20. One end of the guide pipe 20 passes through the interior of the installation box 14 and connects to the interior of the fixed box 13. The other end of the guide pipe 20 passes through the inner wall of the installation box 14 and extends to the outside. The other end of the guide pipe 20 is equipped with a discharge pipe 21. A valve is fixedly installed on the outer wall of the discharge pipe 21. The collected lead liquid will flow along the guide pipe 20. When it is necessary to discharge the lead liquid for subsequent processing or testing, the valve fixedly installed on the outer wall of the discharge pipe 21 can be opened, and the lead liquid will flow out through the discharge pipe 21 to a designated container or equipment. When it is not necessary to discharge the lead liquid, the valve can be closed to prevent lead liquid leakage and ensure the safety and stability of the entire device operation.

[0032] Example 8: This embodiment provides a pyrometallurgical antimony slag lead separation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] The outer wall of the housing 1 has an opening groove 4 located on one side of the first filter plate 6. A rotating baffle 5 is rotatably installed in the opening groove 4, and a retaining sleeve 22 is fixedly installed on one side of the rotating baffle 5. A limiting hole is opened at the position opposite to the retaining sleeve 22. The same insert rod 19 is movably connected between the retaining sleeve 22 and the limiting hole. When it is necessary to clean the first filter plate 6, the insert rod 19 can be pulled out from the retaining sleeve 22 and the limiting hole to release the limiting of the rotating baffle 5. Then, the rotating baffle 5 is rotated to open the opening groove 4. At this time, the operator can perform corresponding operations on the first filter plate 6 through the opening groove 4. After the operation is completed, the rotating baffle 5 is rotated back to its original position, and the insert rod 19 is inserted into the retaining sleeve 22 and the limiting hole to re-limit the rotating baffle 5, ensuring the sealing of the inside of the housing 1 and the normal operation of the device.

[0034] Working principle: First, the worker feeds the pyrometallurgical antimony slag to be separated into the device through the feed pipe 2 on the top surface of the box 1. The bottom end of the feed pipe 2 precisely connects with the guide plate 7 on the top surface of the first filter plate 6. Under the guidance of the guide plate 7, the slag falls steadily onto the surface of the first filter plate 6, which can intercept coarse antimony slag particles. The lead liquid after preliminary filtration falls through the pores of the first filter plate 6 and onto the second filter plate 9, which is also fixed to the inner wall of the box 1. The first guide plate 10 on the top surface of the second filter plate 9 guides the lead liquid to be evenly distributed, further filtering the fine slag, completing the secondary filtration. The lead liquid after secondary filtration flows along the second guide plate 12 fixed by the two mounting blocks 11 on the bottom surface of the second filter plate 9. The liquid lead slides down and eventually falls onto the mounting plate 15. The guide channel 16 on the top surface of the mounting plate 15 guides the liquid lead into the fixed box 13 on one side of the bottom surface inside the box 1. The liquid lead entering the fixed box 13 will be further purified by the stirring component. The core of the stirring component is the stirring auger 17, which is made of high-temperature resistant alloy and can withstand the high temperature environment during the liquid lead separation process, avoiding corrosion or deformation. It is driven to rotate by the servo motor 3 on the outer wall of the box 1. During the rotation, it can break the fine slag coating layer remaining on the surface of the liquid lead, causing the fine slag to settle. At the same time, multiple heating tubes 18 evenly distributed on the inner wall of the fixed box 13 surround the stirring auger 17, continuously maintaining the appropriate temperature for the liquid lead to flow and preventing the liquid lead from solidifying and clogging.

[0035] The purified lead liquid, after being stirred and refined, enters the installation box 14 through the connecting structure between the fixed box 13 and the installation box 14. The installation box 14 is lined with coolant, which conducts temperature to the surface of the guide pipe 20, rapidly cooling the lead liquid to meet the temperature requirements for subsequent processing. The operator can control the valve on the outer wall of the discharge pipe 21 to achieve quantitative discharge of the purified lead liquid. The coarse antimony slag accumulated on the first filter plate 6 can be cleaned by opening the rotating baffle 5 in the opening slot 4 on the outer wall of the box 1, pulling out the sleeve 22 and the insertion rod 19 in the limiting hole of the box 1, thus completing the entire slag-lead separation process.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
