Description

Technical Field

[0001] This utility model relates to the field of flue dust material recycling technology, and in particular to a lead-indium flue dust material recycling device. Background Technology

[0002] Lead-indium flue dust recovery equipment is an important device for processing lead-indium flue dust generated during the production processes of industries such as metallurgy, in order to recover valuable metals such as lead and indium. It provides raw materials for subsequent metal refining through the collection, storage, and preliminary treatment of the flue dust. In practical applications, lead-indium flue dust recovery equipment typically requires the following structure:

[0003] 1. Main recycling bin: As the core structure, it is used to hold the ash material, and its material must have good wear resistance and corrosion resistance;

[0004] 2. Feeding mechanism: including components such as the feeding hopper, used to transport lead-indium flue dust to the recycling bin;

[0005] 3. Smoke and dust treatment components: such as ventilation ducts, dust removal equipment, etc., used to treat smoke and dust generated during the recycling process and reduce environmental pollution;

[0006] 4. Collection bin: Located inside or at the bottom of the recycling bin, used to collect pre-treated soot material.

[0007] Currently, in order to achieve effective recycling of lead-indium flue dust, manufacturers have adopted a variety of equipment and methods. Some manufacturers use traditional gravity settling recycling devices, which use the gravity of flue dust particles to achieve separation. Other manufacturers use cyclone recycling devices, which separate flue dust and gas through centrifugal force. Some manufacturers have also launched combined recycling devices that combine multiple recycling principles to improve recycling efficiency.

[0008] However, the above-mentioned implementation methods still have the following problems. In terms of material discharge, most methods rely on manually opening the discharge port at the bottom of the recycling bin, which is not only inefficient but also poses a risk of operators coming into contact with harmful ash. In terms of foreign matter handling, most devices lack effective filtration methods, and large particles in the ash can easily enter subsequent processing equipment, causing equipment wear and blockage, affecting the quality of the recycled products, and interfering with the particle size-based recycling process. In addition, the filter components of existing devices are difficult to disassemble and clean, and the filtration effect decreases after long-term use, yet timely maintenance is not possible. To address this problem, this application proposes a solution: designing a lead-indium ash material recycling device equipped with an automatic discharge mechanism and a detachable foreign matter filtration mechanism. This device can automatically control the discharge, reduce manual operation, lower the risk of personnel contact, and efficiently filter large particles. Furthermore, the filtration mechanism is easy to disassemble and clean, ensuring the stable and efficient operation of the recycling process. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a lead-indium flue dust recycling device. It solves the problem that most devices rely on manually opening the bottom discharge port of the recycling bin, which is not only inefficient but also poses a risk of operator contact with harmful flue dust. Furthermore, in terms of foreign matter handling, most devices lack effective filtration methods, allowing large particles in the flue dust to easily enter subsequent processing equipment, causing wear and blockages and affecting the quality of the recycled products.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A lead-indium flue dust recycling device includes a recycling bin, an inlet fixedly connected to the upper surface of the recycling bin, two guide plates for buffering fixedly connected inside the inlet, a push block movably connected inside the recycling bin, fixing blocks fixedly connected to both the front and rear sides of the push block, a lead screw rotatably connected inside the recycling bin, a filter cover movably engaged inside the recycling bin, a connecting block fixedly connected to the lower surface of the filter cover, a screw threaded into the connecting block, the screw threaded into the recycling bin, a limit groove provided at the outlet of the recycling bin, a baffle plate movably engaged in the limit groove, and a servo motor fixedly mounted on the right surface of the recycling bin, the output shaft of the servo motor fixedly connected to the lead screw.

[0012] Preferably, the lead screw is threadedly connected to the push block, and the inner wall of the recycling bin has two slots, which are respectively movably connected to two fixed blocks.

[0013] Preferably, a locking block is fixedly connected to the lower surface of the baffle, and a cylinder is fixedly installed on the lower surface of the recycling bin, with the cylinder piston fixedly connected to the locking block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By starting the servo motor, its output shaft will drive the fixed lead screw to rotate. During the rotation, the push block sleeved on it will move due to the screw action. As the push block moves, it can push the flue ash along with it. When the cylinder is started, its piston will drive the fixed baffle to move together. At this time, the baffle will be fully engaged in the limiting groove opened on the surface of the recycling box, the discharge port will open, and the flue ash can be discharged. The whole process realizes the automatic discharge of flue ash material, reduces manual operation, and improves the degree of automation and work efficiency.

[0016] 2. After being buffered by two guide plates, the soot first passes through a filter cover for filtration. The filter cover removes large particles of foreign matter from the soot, reducing wear on the device and lowering maintenance costs and replacement frequency. After a period of collection, the screw is turned to open the limit lock between the filter cover and the recycling box. At this point, the filter cover can be disassembled to remove foreign matter. The overall filtration process removes large particles of foreign matter, which helps improve the quality of the recycled product. Attached Figure Description

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of material discharge, which mostly relies on manually opening the bottom discharge port of the recycling bin. This method is not only inefficient but also poses a risk of operators coming into contact with harmful ash. In terms of foreign matter handling, most devices lack effective filtration methods, allowing large particles of foreign matter in the ash to easily enter subsequent processing equipment, causing equipment wear and blockage, and affecting the quality of the recycled products. The overall approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a lead-indium flue dust material recycling device, including a recycling box 1. A feed inlet 2 is fixedly connected to the upper surface of the recycling box 1. Two guide plates 9 for buffering are fixedly connected inside the feed inlet 2. A push block 8 is movably connected inside the recycling box 1. Fixing blocks 10 are fixedly connected to both the front and rear sides of the push block 8. A lead screw 7 is rotatably connected inside the recycling box 1. A filter cover 3 is movably engaged inside the recycling box 1. A connecting block 5 is fixedly connected to the lower surface of the filter cover 3. A screw 4 is threaded into the connecting block 5. The screw 4... The recycling bin 1 is threaded and has a limit groove 15 at its outlet. A baffle 11 is movably engaged within the limit groove 15. A servo motor 6 is fixedly mounted on the right surface of the recycling bin 1. The output shaft of the servo motor 6 is fixedly connected to a lead screw 7. In use, the feed inlet 2 is aligned with the conveyor belt that transports lead-indium flue dust. When the material falls into the recycling bin 1, it is buffered by two guide plates 9 fixed inside the feed inlet 2 to prevent the flue dust from falling into the recycling bin 1 all at once and raising a large amount of dust. After the flue dust has accumulated for a period of time, the output shaft of the servo motor 6 is activated. The fixed lead screw 7 will rotate, and the push block 8 sleeved on the lead screw 7 will move due to the screw thread. The push block 8 will move the flue ash along with it. The piston of the cylinder 14 will drive the fixed baffle 11 to move together. At this time, the baffle 11 will be fully engaged in the limiting groove 15 opened on the surface of the recycling box 1, the discharge port will open, and the flue ash can be discharged. The whole process realizes the automatic discharge of flue ash material, reduces manual operation, improves the degree of automation and work efficiency. After discharge, the lead-indium flue ash material and sulfur The acid solution is mixed in a reactor equipped with a stirrer. Stirring promotes full contact between the material and sulfuric acid. Under optimized temperature, sulfuric acid concentration and reaction time conditions, indium is transferred into the solution in ionic form. The leachate enters the reaction tank of this unit, where iron powder is added to cause a reduction reaction that removes impurities such as bismuth and iron, reducing the difficulty of subsequent processing. 30% (V) P2O4 + 70% (V) aviation kerosene is used as the extractant. In the extraction tower or mixing and clarifying tank, the extractant selectively extracts indium, allowing indium to enter the organic phase from the aqueous phase, thus achieving separation from impurities.

[0027] The lead screw 7 is threadedly connected to the push block 8. Two slots 12 are provided on the inner wall of the recycling bin 1, and each slot 12 is movably connected to one of the two fixed blocks 10. A block 13 is fixedly connected to the lower surface of the baffle plate 11. A cylinder 14 is fixedly installed on the lower surface of the recycling bin 1, and the piston of the cylinder 14 is fixedly connected to the block 13. After being buffered by the two guide plates 9, the ash first passes through the filter cover 3 for filtration. The filter cover 3 filters out large particles of foreign matter in the ash, reducing wear on the device and lowering maintenance costs and replacement frequency. After a period of collection, the screw 4 is turned to open the limiting fixation between the filter cover 3 and the recycling bin 1. At this time, the filter cover 3 can be... The process involves disassembly and treatment of internal foreign matter. Large particles are removed by filtration, which helps improve the quality of the recycled product. The extracted organic phase is first acid-washed to remove impurity ions before entering the back-extraction unit. In a specific reaction vessel, back-extraction agents such as hydrochloric acid are added to allow indium to return from the organic phase to the aqueous phase for enrichment. The back-extracted aqueous phase is first neutralized to remove iron and tin, then zinc powder is added to replace other metallic impurities. Finally, aluminum sheets are used to replace indium to obtain sponge indium. Each step is carried out in different reaction vessels. The sponge indium is heated and melted under a caustic soda cover. Impurities react with the caustic soda and enter the slag to obtain crude indium. The wastewater is treated with lime and anionic polyacrylamide to remove heavy metal ions, phosphate ions, and sulfate ions before being discharged in compliance with standards.

[0034] Screw 7: Rotates inside the recycling bin 1 and is threadedly connected to push block 8. When it rotates, it pushes push block 8 to move the ash inside the recycling bin 1.

[0035] Push block 8: Moves under the drive of lead screw 7, pushes the ash, and works with baffle plate 11 to realize the automatic discharge of ash material;

[0036] Guide plate 9: Fixed inside the feed inlet 2, it buffers the falling soot and prevents a large amount of soot from falling into the recycling bin 1 at once and raising dust.

[0043] Working principle:

[0044] During use, the feed inlet 2 is aligned with the conveyor belt that transports lead-indium flue dust. When the material falls into the recycling bin 1, it is buffered by two guide plates 9 fixed inside the feed inlet 2 to prevent the flue dust from falling into the recycling bin 1 all at once and raising a large amount of dust. After the flue dust has accumulated for a period of time, the output shaft of the servo motor 6 is started, which drives the fixed lead screw 7 to rotate. During the rotation of the lead screw 7, the push block 8 sleeved on it is moved by the thread action. The push block 8 moves along with the flue dust. The piston of the cylinder 14 is started, which drives the fixed baffle 11 to move together. At this time, the baffle 11 is completely closed. The filter is engaged within the limiting groove 15 on the surface of the recycling bin 1, opening the discharge port to allow the ash to be discharged. This achieves automatic discharge of ash materials, reducing manual operation and improving automation and work efficiency. After being buffered by two guide plates 9, the ash first passes through the filter cover 3 for filtration. The filter cover 3 filters out large particles of foreign matter in the ash, reducing wear on the device and lowering maintenance costs and replacement frequency. After a period of collection, the screw 4 is turned to open the limiting groove 15 between the filter cover 3 and the recycling bin 1. At this point, the filter cover 3 can be disassembled to remove foreign matter. The overall process involves filtration to remove large particles of foreign matter, which helps improve the quality of the recycled products. After discharge, the lead-indium-containing flue dust is mixed with sulfuric acid solution in a reactor equipped with a stirrer. Stirring ensures full contact between the material and the sulfuric acid. Under optimized temperature, sulfuric acid concentration, and reaction time conditions, indium is transferred into the solution in ionic form. The leachate enters the reaction tank of this unit, where iron powder is added to undergo a reduction reaction to remove impurities such as bismuth and iron, reducing the difficulty of subsequent processing. 30% (v) P2O4 + 70% (v) aviation kerosene is used as the extractant. In an extraction tower or mixing and clarifying tank, the extractant selectively extracts indium. Indium is extracted by moving it from the aqueous phase to the organic phase to separate it from impurities. The extracted organic phase is first acid-washed to remove impurity ions, and then enters the back-extraction unit. In a specific reaction vessel, back-extraction agents such as hydrochloric acid are added to allow indium to return from the organic phase to the aqueous phase for enrichment. The back-extracted aqueous phase is first neutralized to remove iron and tin, and then zinc powder is added to replace other metallic impurities. Finally, aluminum sheets are used to replace indium to obtain sponge indium. Each step is carried out in different reaction vessels. The sponge indium is heated and melted under a caustic soda cover. Impurities react with the caustic soda and enter the slag to obtain crude indium. The wastewater is treated with lime and anionic polyacrylamide to remove heavy metal ions, phosphate ions, and sulfate ions before being discharged in compliance with standards.
