Description

Technical Field

[0001] This utility model relates to the field of metallurgical waste slag recycling technology, and in particular to an antimony slag cyclone separation and recycling device. Background Technology

[0002] Antimony slag is antimony-containing waste residue generated during antimony smelting. It typically contains 5%-30% antimony, as well as heavy metals such as lead and arsenic. Antimony slag sorting and recycling is a process that extracts antimony and other valuable metals from the waste residue through technologies such as crushing, gravity separation, flotation, or hydrometallurgy. The recovered antimony can be reused in industrial fields such as flame retardants, alloys, and batteries, while the separated lead, arsenic, and other elements can also be further utilized. This technology not only improves resource utilization and reduces dependence on primary ore, but also avoids heavy metal pollution caused by waste residue accumulation, thus possessing both economic and environmental value. With the increasing scarcity of antimony resources and stricter environmental requirements, antimony slag recycling has become an important link in green metallurgy and the circular economy.

[0003] Traditional hydrocyclone sorting and recovery devices lack a self-cleaning structure, which easily leads to blockage of the drain outlet. Blockage will obstruct water flow, cause pressure imbalance inside the hydrocyclone, significantly reduce sorting efficiency, and in severe cases, may completely stop working, reducing system operating efficiency. At the same time, long-term blockage may cause equipment overload or local pressure accumulation, leading to mechanical damage such as pipe rupture and seal failure, shortening equipment life, increasing maintenance costs, and increasing the risk of equipment damage.

[0004] Therefore, in view of the problem that the traditional cyclone separation and recovery device lacks a self-cleaning structure, which reduces the system operating efficiency, shortens the equipment life and increases the risk of equipment damage, an antimony slag cyclone separation and recovery device with a self-cleaning structure can be designed to solve the above problems. Utility Model Content

[0007] Preferably, a swirling flow is generated inside the cylinder, and the waste residue is subjected to centrifugal force, causing objects of different densities and volumes to be subjected to different degrees of force. Heavier substances are pushed to the outside and deposited downwards along the slope of the cone until they are discharged through the drain outlet. Lighter substances accumulate in the middle until they are discharged from the middle of the cylinder. During this process, a flow sensor is used to detect the flow rate at the drain outlet to determine whether the device is blocked. If an abnormality is found, a control signal is transmitted to the drive component, causing the drive component to output power to the slider, which moves the slider to the blocked drain outlet. Then, the telescopic component outputs power to move the first booster pump and the multi-stage telescopic pipe to the bottom of the drain outlet. The multi-stage telescopic pipe then extends until the high-pressure nozzle enters the drain outlet. At the same time, the first booster pump outputs pressure to deliver water from the slider to the high-pressure nozzle to unclog and clean the blocked drain outlet.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Antimony slag is a solid residue generated during the smelting of antimony ore or the treatment of antimony-containing industrial waste. Its main components are incompletely extracted antimony and its compounds, and it may also contain heavy metal impurities such as arsenic, lead, and iron. It is mostly in granular or powder form and has high recycling value. However, if not handled properly, it can cause serious environmental pollution. Therefore, it is necessary to sort and recycle antimony slag.

[0025] Antimony slag recycling has many uses: 1. Resource recycling: Antimony is an important strategic metal, widely used in flame retardants, alloys, semiconductors, and other fields. Recycling antimony slag can reduce dependence on primary ore mining and lower production costs; 2. Environmental protection: If heavy metals in antimony slag are dumped indiscriminately, they will pollute soil and water sources through rainwater leaching, and even endanger human health through the food chain. Sorting and recycling can effectively reduce the emission of toxic waste; 3. Economic benefits: The antimony content in antimony slag is usually still 5%-20%. Through efficient sorting, its grade can be increased to more than 30%, and further purification through smelting can create considerable economic value.

[0026] Antimony slag sorting and recycling refers to the process of separating and purifying valuable metals from antimony slag through physical or chemical methods. Among them, hydrocyclone separation technology is widely used due to its high efficiency and low energy consumption. This technology uses centrifugal force to separate particles of different densities into layers in a hydrocyclone. Antimony minerals, due to their higher density, are enriched in the bottom flow, while light impurities are discharged with the overflow, thus achieving the initial enrichment of antimony.

[0027] Traditional antimony slag hydrocyclone separation and recovery devices are prone to clogging of the discharge port, usually due to the following reasons: 1. Antimony slag particle deposition: During the hydrocyclone separation process, high-density antimony minerals are enriched towards the bottom discharge port under the action of centrifugal force. However, due to their high viscosity, they are easy to accumulate near the discharge port, gradually forming a blockage; 2. Impurity scaling: Antimony slag often contains impurities such as silicates and iron oxides. These substances are easy to form a hard scaling layer on the inner wall of the discharge port, hindering the smooth discharge of slag slurry; 3. Excessive slag slurry concentration: If the concentration of antimony slag in the feed is too high or the flow rate is too low, it will lead to faster particle settling speed, exacerbating the risk of accumulation at the discharge port.

[0028] Blockage of the drain outlet leads to many adverse consequences: 1. Decreased sorting efficiency: Blockage disrupts the internal flow field balance of the hydrocyclone, preventing effective classification of antimony minerals. Some high-grade antimony slag may be lost with the overflow, reducing the recovery rate; 2. Abnormal equipment operation: Poor drainage can increase the internal pressure of the hydrocyclone, potentially causing vibration, noise, or even pipe rupture. In severe cases, emergency shutdown and repair are required; 3. Increased maintenance costs: Manual cleaning of blockages requires frequent disassembly of equipment, which not only delays production but may also damage seals or linings, increasing spare parts replacement costs; 4. Environmental pollution risk: If blockage causes system shutdown, untreated antimony slag may leak, and the toxic heavy metals such as arsenic and lead contained within may pollute the surrounding soil and water bodies.

[0029] In summary, the clogging problem at the discharge port of traditional antimony slag cyclone separation and recovery devices is mainly caused by factors such as antimony slag particle deposition, impurity scaling, excessively high slurry concentration, and equipment structural defects. Clogging can lead to a series of adverse consequences, including decreased separation efficiency, abnormal equipment operation, increased maintenance costs, and environmental pollution risks, which seriously affect production stability and economic benefits.

[0030] To address this issue, it is necessary to develop more sophisticated and intelligent antimony slag cyclone separation and recovery devices to further improve the recovery rate of antimony slag separation technology, reduce energy consumption, and promote the sustainable development of resource recycling and green mining.

[0031] Please see Figures 1-5 This utility model provides an embodiment of an antimony slag cyclone separation and recovery device, comprising a cylinder 1; the cylinder 1 is provided with several cylinders, a cone 2 is fixedly connected to the bottom of the cylinder 1, a drain port 3 is fixedly connected to the bottom of the cone 2, a flow sensor 4 is fixedly connected to the bottom of the drain port 3, a support frame 5 is fixedly connected to the bottom of the cone 2, a drive assembly is fixedly connected to the support frame 5, the drive assembly and the flow sensor 4 are electrically connected, a slider 9 is connected to the output end of the drive assembly, the drive assembly is used to drive the slider 9 to perform linear motion, a telescopic assembly is fixedly connected to the slider 9, a first booster pump 11 is fixedly connected to the output end of the telescopic assembly, the telescopic assembly is used to control the first booster pump 11 to perform telescopic motion, a multi-stage telescopic pipe 12 is fixedly connected to the output end of the first booster pump 11, and a high-pressure nozzle 13 is fixedly connected to the other end of the multi-stage telescopic pipe 12. A cyclone is generated inside the cylinder 1, and the waste slag is subjected to centrifugal force, causing different densities to be separated. Objects of different volumes are subjected to forces of varying degrees. Heavier materials are pushed to the outside and deposited downwards along the slope of cone 2 until they are discharged through drain port 3. Lighter materials accumulate in the middle until they are discharged from the middle of cylinder 1. During this process, flow sensor 4 detects the flow rate of drain port 3 to determine if the device is blocked. If an abnormality occurs, a control signal is transmitted to the drive component, causing the drive component to output power to slider 9, which moves slider 9 to the blocked drain port 3. Then, the telescopic component outputs power to move the first booster pump 11 and the multi-stage telescopic tube 12 to below drain port 3. The multi-stage telescopic tube 12 then extends until the high-pressure nozzle 13 enters drain port 3. At the same time, the first booster pump 11 outputs pressure to deliver water from slider 9 to the high-pressure nozzle 13 to unclog and clean the blocked drain port 3. The flow sensor 4 in this device is a DN40.

[0032] Please see Figures 1-5In this embodiment, the driving assembly includes a guide rail 801, a motor 802, and a threaded rod 803. The guide rail 801 is fixedly connected to the support frame 5, and the motor 802 is fixedly connected to one side of the guide rail 801. The output end of the motor 802 is fixedly connected to the threaded rod 803. The motor 802 drives the threaded rod 803 to rotate. The threaded rod 803 is rotatably connected to the guide rail 801, and the threaded rod 803 is threadedly connected to the slider 9. The motor 802 outputs torque to the threaded rod 803, causing the threaded rod 803 to rotate on the guide rail 801, thereby driving the slider 9, which is threadedly connected to the threaded rod 803, to move linearly. The telescopic assembly includes a hydraulic cylinder 1001 and a hydraulic rod 1002. The hydraulic cylinder 1001 is fixedly connected to the slider 9, and the output end of the hydraulic cylinder 1001 is fixedly connected to the hydraulic rod 1002. 002, the hydraulic cylinder 1001 is used to push the hydraulic rod 1002 to move linearly. The other end of the hydraulic rod 1002 is fixedly connected to the first booster pump 11. The hydraulic cylinder 1001 outputs pressure to the hydraulic rod 1002, pushing the hydraulic rod 1002 to move linearly, which in turn drives the first booster pump 11 to move linearly toward the drain outlet 3. A water tank 14 is fixedly connected to the support frame 5. A second booster pump 15 is fixedly connected to the water tank 14. A flexible conveying pipe 16 is fixedly connected to the output end of the second booster pump 15. The other end of the flexible conveying pipe 16 is fixedly connected to the slider 9. Clean water is introduced into the water tank 14. The second booster pump 15 outputs pressure to transport the water source in the water tank 14 to the flexible conveying pipe 16. The flexible conveying pipe 16 then transports the water source to the slider 9, thus realizing the water supply.

[0033] Please see Figures 1-4 In this embodiment, a feed pipe 101 is provided on one side of the cylinder 1, and a discharge pipe 102 is provided above the cylinder 1. An arc-shaped plate 20 is fixedly connected inside the cylinder 1. Waste residue is conveyed into the cylinder 1 through the feed pipe 101. The arc-shaped plate 20 separates the feed pipe 101 and the discharge pipe 102, so that the non-ferrous metals in the waste overflow from the discharge pipe 102 after swirling. A swirling control valve 17 is fixedly connected to the other end of the feed pipe 101, and a conveying main pipe 18 is fixedly connected to the other end of the swirling control valve 17. The swirling control valve 17 controls the switch to convey the waste residue in the conveying main pipe 18 to each feed pipe 101. A pressure gauge 19 is fixedly connected to the main conveying pipe 18. A vortex control valve 17 and a flow sensor 4 are electrically connected. The pressure gauge 19 detects and displays the pressure value in the main conveying pipe 18. When the flow sensor 4 detects a blockage in the device, it closes the vortex control valve 17 until the device is cleared. A sludge storage tank 6 is provided below the drain outlet 3, and a recovery tank 7 is provided below the discharge pipe 102. The sludge storage tank 6 and the recovery tank 7 are fixedly connected to the support frame 5. The waste separated from the slag falls into the sludge storage tank 6 through the drain outlet 3, and the non-ferrous metals separated from the slag fall into the recovery tank 7 through the discharge pipe 102.

[0034] During operation, the vortex control valve 17 controls the switch to transport the waste residue in the main conveying pipe 18 to the various feed pipes 101. The waste residue is then transported into the cylinder 1 through the feed pipes 101. An arc-shaped plate 20 separates the feed pipes 101 and the discharge pipe 102. A vortex is then generated inside the cylinder 1, and the waste residue is subjected to centrifugal force. Objects of different densities and volumes experience different degrees of force; heavier materials are pushed to the outside and deposit downwards along the slope of the cone 2 until they are discharged through the drain outlet 3 and fall into the sludge storage tank 6. Lighter materials accumulate in the middle and overflow from the discharge pipe 102, falling into the recovery tank 7. During this process, the flow sensor 4 detects the flow rate at the drain outlet 3 to determine if the device is blocked. If an abnormality occurs, the vortex control valve 17 closes, transmitting a control signal to the drive assembly to activate the power supply. The machine 802 outputs torque to the threaded rod 803, causing the threaded rod 803 to rotate on the guide rail 801. This drives the slider 9, which is threaded onto the threaded rod 803, to move to the blocked drain outlet 3. Then, the second booster pump 15 outputs pressure to transport the water source in the water tank 14 to the flexible delivery pipe 16. The flexible delivery pipe 16 then transports the water source to the slider 9, thus supplying water. Next, the hydraulic cylinder 1001 outputs pressure to the hydraulic rod 1002, pushing the hydraulic rod 1002 to move linearly. This drives the first booster pump 11 and the multi-stage telescopic pipe 12 to move below the drain outlet 3. The multi-stage telescopic pipe 12 then extends until the high-pressure nozzle 13 enters the drain outlet 3. At the same time, the first booster pump 11 outputs pressure to transport the water source in the slider 9 to the high-pressure nozzle 13, thus clearing and cleaning the blocked drain outlet 3.

[0035] Through the above steps, the flow sensor 4 is used for real-time detection, and then the high-pressure nozzle 13, together with multiple power components, is used to automatically dredge and clean the sewage outlet 3. This can promptly remove the antimony slag particles accumulated in the sewage outlet, avoid pressure fluctuations caused by blockage, ensure the stability of the internal flow field of the hydrocyclone, and enable the antimony minerals to be accurately sorted according to density, thereby improving sorting efficiency and stability. It can also reduce maintenance costs and failure risks, and reduce the wear rate of the equipment. This solves the problem that traditional hydrocyclone sorting and recovery devices lack a self-cleaning structure, which reduces system operating efficiency, shortens equipment life, and increases the risk of equipment damage.
