Description

Technical Field

[0001] The invention relates to a blowing slag air quenching system, belonging to the technical field of copper smelting. Background Art

[0002] Copper smelting typically involves a series of processes to extract copper from copper ore, including roasting, smelting, and refining. During these processes, impurities, non-metallic components, and other unwanted substances in the ore are converted into a solid residue, known as converting slag. During the roasting stage of copper smelting, the ore is typically heated to remove volatile components and moisture. The residue produced by roasting, which includes iron oxide, silicates, sulfates, etc., is called roasting slag. In the further smelting stage, the roasted product is smelted together with copper concentrate at high temperatures, the molten metallic copper is collected, and some non-metallic elements and impurities produced in the process form converting slag.

[0003] Common components in blowing slag include oxides, sulfides and other silicates, but it may also include some harmful substances or heavy metals, so it needs to be treated.

[0024] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0025] 1. The present invention uses air quenching of the blown slag, that is, by introducing high-pressure gas and purified water into the central bin to cool and solidify the liquid blown slag.

This minimizes the emission and diffusion of dust generated during the air quenching process, effectively reducing pollution to the environment.

[0027] 3. The present invention facilitates the further retention and cooling of the blown slag particles by providing an arc-shaped guide plate, and also facilitates the introduction of the blown slag particles into the outlet of the central bin, thereby facilitating collection and processing by the second transport mechanism.

[0035] The present invention will be described in more detail below with reference to the embodiments.

[0036] Example 1

[0037] See also Figure 1 The blowing slag air quenching system of this embodiment includes a central warehouse 1, which is respectively connected to:

[0038] Feed pipeline 3: includes a terminal chute 301. The input end of the terminal chute 301 is connected to the blow slag outlet through a pipeline, and is used to input liquid blow slag into the central bin 1. The output end of the terminal chute 301 penetrates the side wall of the central bin 1 and extends into the interior of the central bin 1.

[0039] Air inlet pipe 4: connected to the air source, used to introduce high-pressure gas into the central bin 1 to cool the liquid blown slag and solidify it into particles. In this embodiment, the air source is nitrogen. Nitrogen has the advantages of stable chemical properties, clean and environmentally friendly, uniform cooling, and high cooling efficiency, and is suitable for promotion and use;

[0040] Water inlet pipe 5: connected to the water source, used to introduce purified water into the central bin 1 and perform secondary cooling on the solidified blown slag particles;

[0041] Dust removal pipeline: including an ash discharge pipe 102 fixed to the top of the central bin 1, used to discharge the dust in the central bin 1. In this embodiment, a thermal resistor for measuring the flue gas temperature is installed on the ash discharge pipe 102 to facilitate timely detection of unexpected conditions;

[0042] Discharge pipeline: used to discharge the cooled blown slag particles and slurry;

[0043] Also includes:

[0044] Dust removal component: connected to the dust removal pipeline, used to purify the dust discharged from the dust removal pipeline and discharge it into the atmosphere.

[0045] As can be seen from the above description, the liquid converted slag output from the previous process step is fed into the central bin 1 through the input end of the terminal chute 301 of the feed pipeline 3. Simultaneously, high-pressure gas is introduced through the air inlet pipeline 4 to exchange heat with the liquid converted slag, thereby rapidly cooling the converted slag and solidifying it into particles. Atomized water is then introduced into the central bin 1 through the water inlet pipeline 5. The atomized water can perform secondary cooling on the converted slag particles, further reducing the temperature of the converted slag and ensuring its complete solidification.

[0046] Since a large amount of dust is generated during the cooling and solidification process of the blowing slag, a dust removal pipeline is provided and the dust in the central bin 1 is discharged through the ash discharge pipe 102, effectively removing the floating dust and impurities in the system to keep the system clean and operating normally. At the same time, in order to ensure that the discharged dust meets the emission standards and environmental protection requirements, the dust discharged from the ash discharge pipeline is purified through the provision of a dust removal component and finally discharged into the atmosphere.

[0047] Therefore, the beneficial effect of the present invention is that, by providing the air inlet pipe 4, high-pressure gas is introduced into the central bin 1 to rapidly cool the liquid blown slag and solidify it into particles, thereby achieving efficient and rapid cooling of the blown slag, thereby effectively improving the processing efficiency of the blown slag and reducing the cooling time;

[0048] At the same time, by setting up the water inlet pipe 5, the purified water is atomized and introduced into the central bin 1, which can perform secondary cooling on the cooled and solidified blown slag particles, thereby further reducing the temperature of the blown slag, ensuring its complete solidification, and improving the quality and consistency of the output blown slag;

[0049] In order to ensure that no pollution is caused to the environment, the dust removal pipeline and the dust removal components are set up to effectively discharge the dust generated in the central warehouse 1, reducing environmental pollution and cleaning work. The dust removal pipeline can also purify the discharged dust to ensure that the dust discharged into the atmosphere meets environmental protection requirements;

[0050] The overall structural layout of the system is relatively simple, easy to operate and maintain, the various pipelines and components are tightly connected, the structure is compact, and the footprint is relatively small. It is suitable for production environments of different scales and site restrictions, and is suitable for promotion and use.

[0051] Furthermore, the air inlet pipeline 4 includes an air inlet valve and an air storage tank 401, an air outlet valve, a regulating valve for adjusting the amount of air input into the pipeline, and a granulation nozzle 101 for ejecting the gas, which are sequentially connected through a pipeline. The input end of the air inlet valve is connected to the air source, and the output end of the granulation nozzle 101 penetrates the side wall of the central bin 1 and extends into the interior of the central bin 1.

[0052] A branch line 402 is connected between the air inlet line 4 and the water inlet line 5 . One end of the branch line 402 is arranged at the output end of the regulating valve, and the other end is arranged at the output end of the manual valve 2.

[0053] In this embodiment, the granulation nozzle 101 is specifically an air quenching nozzle, the air quenching medium is nitrogen, and the regulating valve is connected to a DCS display screen for displaying the flow rate in the air inlet pipeline 4.

[0054] As can be seen from the above description, the gas storage tank 401 is provided to ensure a stable pressure of the quenching gas. In conjunction with the setting of the regulating valve, the gas volume input from the pipeline can be adjusted as needed. This allows for flexible control of the cooling and solidification process of the blown slag according to process requirements and actual conditions. Adjusting the gas volume can meet the needs of different quenching stages, thereby improving the quality and consistency of the quenched product.

[0055] At the same time, the granulating nozzle 101 allows the gas to be injected into the central bin 1 in the form of fine particles, thereby providing more precise gas distribution and cooling effect, ensuring uniform cooling and solidification of the blown slag particles. Precise injection can improve the quality of the air-quenched product and reduce problems caused by uneven cooling.

[0056] Moreover, through the setting of the branch pipeline 402, the air inlet pipeline 4 and the water inlet pipeline 5 can be operated in conjunction or independently as needed, thereby improving the flexibility of adjustment, enabling the system to adapt to different process parameters and production requirements, and providing more precise control and adjustment capabilities.

[0057] Furthermore, the water inlet pipeline 5 includes a manual valve 1, a water supply tank 501, an atomizing pipeline 502, a check valve and a manual valve 2 connected in sequence through pipelines. The atomizing pipeline 502 includes two atomizing water pumps connected in parallel with each other through pipelines. The input end of the manual valve 1 is connected to the water source, and the output end of the manual valve 2 is connected to the input end of the granulating nozzle 101.

[0058] In this embodiment, a flow regulating valve is provided on the water inlet pipe 5 , and the flow regulating valve is externally connected to a DCS display screen.

[0059] From the above description, it can be seen that by setting the manual valve 1, the input amount of the water source can be adjusted as needed. By setting two atomizing water pumps, one is used and the other is kept in reserve at ordinary times. When the blowing slag flow is particularly large, two can be started at the same time to adapt to different wind quenching conditions. The check valve plays a role in preventing backflow in the pipeline, ensuring that water can only flow from the water supply tank 501 to the central warehouse 1, preventing reverse flow, maintaining the normal operation of the system, and avoiding problems and safety hazards caused by backflow.

[0060] Furthermore, the dust removal pipeline includes an air blowing pipeline 9, an air storage tank 901, a dust removal device 2, an exhaust pipeline 10 and an exhaust fan 11 connected in sequence. The input end of the air blowing pipeline 9 is connected to the compressed air source, the output end of the exhaust fan 11 is connected to the chimney, the dust removal device 2 is connected to the output end of the dust removal pipeline, and the dust removal device 2 is also connected to a transportation mechanism 201 for discharging the dust absorbed by the dust removal device 2, and the output end of the transportation mechanism 201 is connected to an ash bag 202 for collecting dust.

[0061] In this embodiment, the dust removal device 2 is a sintered plate type dust collector. The surface of the sintered plate of the sintered plate type dust collector is covered with a reinforced PTFE film, which is perfectly combined with the rigid substrate. The sintered plate of the sintered plate type dust collector has self-lubricating properties, excellent hydrophobicity, and high chemical stability such as moisture resistance, acid and alkali corrosion resistance, and oil resistance.

[0062] The transport mechanism 201 is a screw conveyor, which can realize continuous material transportation without frequent start and stop operations, and the material can be transported continuously, which improves the efficiency and continuity of transportation and is suitable for promotion and use.

[0063] As can be seen from the above description, the dust can be effectively absorbed and collected by the arrangement of the dust removal device 2, and the dust removal device 2 is connected to the output end of the dust removal pipeline, which can effectively filter and separate the dust before it enters the exhaust pipeline 10, thereby reducing the dust concentration and improving the dust removal effect; by the arrangement of the transport mechanism 1 201 and the ash bag 202, the dust absorbed by the dust removal device 2 can be conveniently discharged and collected, and the transport mechanism 1 201 is connected to the ash bag 202 through the output end to transport the dust from the device to the ash bag, thereby reducing the accumulation of dust and facilitating treatment and cleaning;

[0064] At the same time, when the dust-laden gas passes through the sintered plate from the outer surface of the sintered plate of the sintered plate type dust collector, the dust is retained on the PTFE coating on the surface of the sintered plate. As the dust on the surface of the sintered plate increases, the filter chamber needs to be sprayed and cleaned. Therefore, the blowing pipe 9 is set to spray the sintered plate, so that the dust can fall into the ash hopper under the action of airflow and gravity, and then the dust is transported away by the screw conveyor. The purified gas flows through the pores of the sintered plate into the clean air box, and is discharged into the chimney through the clean air outlet through the fan, and finally discharged into the atmosphere, completing the purification and improving the dust removal efficiency and effect.

[0065] Furthermore, the unloading pipeline includes a transport mechanism 2 6, which is respectively connected to a mud discharge pipeline 7 and a slag discharge pipeline. The mud discharge pipeline 7 includes a mud pool 701 and a mud pump connected in sequence, and the input end of the mud pool 701 is connected to one of the output ends of the transport mechanism 2 6; the slag discharge pipeline includes a transport mechanism 3 8 and a slag bin 801, the input end of the transport mechanism 3 8 is connected to the other output end of the transport mechanism 2 6, and the slag bin 801 is arranged at the output end of the transport mechanism 3 8.

[0066] In this embodiment, the transport mechanism 2 6 is a buried scraper conveyor. The buried scraper conveyor adopts a scraper conveying method and can efficiently transport mud or slag from the source to the destination. Its conveying speed is relatively fast and can meet the transportation needs of large amounts of materials.

[0067] The transport mechanism 3 8 is a large-angle scraper. The large-angle scraper has the advantages of high tilt adaptability, large conveying capacity, flexible conveying angles and routes, automatic control, and space saving. The blowing slag is transported to the slag bin by the large-angle scraper, and finally the air-quenched slag is transported to the concentrate storage by truck.

[0068] From the above description, it can be seen that the unloading material is diverted to the mud discharge pipeline 7 and the slag discharge pipeline through the second transport mechanism 6, which can effectively separate the soft mud and solid blowing slag, facilitate the reuse of the blowing slag, and improve the utilization rate of the blowing slag. Through the setting of the third transport mechanism 8 and the slag bin 801, the blowing slag can be transported to the slag bin 801 for centralized storage, which is convenient for subsequent processing and transportation, reduces the accumulation of materials and the floor space occupied, and improves the processing efficiency.

[0069] Example 2

[0070] The blowing slag quenching system of this embodiment is based on the above-mentioned embodiment 1, and the overall mechanical connection relationship inside the central bin 1 is further defined as follows:

[0071] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5An arc-shaped guide plate 104 is provided in the central warehouse 1, one end of the arc-shaped guide plate 104 is fixed on the inner wall of the central warehouse 1, and the other end is tilted downward, and an arc-shaped mounting plate 103 is spaced apart from the top of the arc-shaped guide plate 104, and the inner arc surfaces of the arc-shaped guide plate 104 and the arc-shaped mounting plate 103 are arranged opposite to each other; a reciprocating cleaning mechanism 12 for cleaning the upper surface of the arc-shaped mounting plate 103 is installed on the side of the arc-shaped mounting plate 103 close to the arc-shaped guide plate 104.

[0072] From the above description, it can be seen that the setting of the arc-shaped guide plate 104 can guide the blowing slag to flow smoothly along the path of the arc-shaped guide plate 104, prevent the accumulation of materials, and enable the materials to flow smoothly to the discharge port of the central warehouse 1, thereby increasing the fluidity of the blowing slag. The reciprocating cleaning mechanism 12 is used to clean the upper surface of the arc-shaped mounting plate 103, promptly remove the dust and impurities accumulated on the arc-shaped mounting plate 103, keep the flow of the blowing slag smooth and the overall cleanliness, and improve the stability and efficiency of the system.

[0073] Furthermore, the reciprocating cleaning mechanism 12 includes a mounting assembly, a cleaning mechanism 13, a driving mechanism 14 and a limiting mechanism 15. The mounting assembly includes a mounting seat 121, a vertical mounting rod 126 and an inverted Y-shaped rod 123. The top of the mounting seat 121 is connected to the arc-shaped mounting plate 103 through a plurality of connecting rods 122. The Y-shaped rod 123 and the vertical mounting rod 126 are respectively fixed on both sides of the bottom end of the mounting seat 121, and an arc-shaped rod 123 is connected between the two branches. A limit block 153 is slidably mounted on the sliding rod 124. A limit mechanism 15 is connected between the limit block 153 and the Y-shaped rod 123. The limit mechanism 15 includes a pair of limit rotating rods 152 arranged on both sides of the Y-shaped rod 123. One end of each limit rotating rod 152 is fixed to the limit block 153, and the other end is fixed to the limit rotating block 151. A pin is fixedly sleeved between the two limit rotating blocks 151, and the pin rotates and passes through the branch of the Y-shaped rod 123.

[0074] A sleeve rod 133 is also fixed on the limit block 153, and a cleaning mechanism 13 is installed on the sleeve rod 133; the driving mechanism 14 is installed at the bottom end of the vertical mounting rod 126, and the output end of the driving mechanism 14 is connected to a bending rod 143, and an arc-shaped swing rod 125 is movably connected between the free end of the bending rod 143 and the cleaning mechanism 13.

[0075] In this embodiment, ribs 16 are installed between the Y-shaped rod 123 and the mounting seat 121 and between the vertical mounting rod 126 and the mounting seat 121 to increase the stability of the structure.

[0076] From the above description, it can be seen that the driving mechanism 14 transmits power to the arc-shaped swing arm 125 through the bending rod 143, so that one end of the arc-shaped swing arm 125 can be driven to rotate. The rotation of one end of the arc-shaped swing arm 125 can drive the other end of the arc-shaped swing arm 125 to move. Since one end of the arc-shaped swing arm 125 rotates to perform a circular motion, it can push or pull the arc-shaped swing arm 125 to perform a reciprocating motion on the track of the arc-shaped slide bar 124. The end of the arc-shaped swing arm 125 on which the cleaning mechanism 13 is installed is limited by the action of the limiting block 153, ensuring that the end of the arc-shaped swing arm 125 on which the cleaning mechanism 13 is installed can reciprocate. At the same time, through the setting of the limiting rotating block 151 and the limiting rotating rod 152, the limiting block 153 is further limited to ensure the stability of the reciprocating motion structure, thereby ensuring the cleaning effect and stability of the cleaning mechanism 13.

[0077] Furthermore, the cleaning mechanism 13 includes a reciprocating rod 131 and a cleaning fan 132. One end of the reciprocating rod 131 is rotatably sleeved on the sleeve rod 133, and the other end is fixedly connected to the cleaning fan 132. The side surface of the reciprocating rod 131 is fixedly connected to the arc-shaped swing rod 125.

[0078] From the above description, it can be seen that since the arc-shaped swing rod 125 will rotate back and forth during the swinging process, it can drive the reciprocating rotating rod 131 to rotate back and forth, so that the cleaning fan 132 can reciprocate and clean the surface of the arc-shaped guide plate 104, and can rotate to clean, which effectively improves the cleaning effect, prevents the accumulation of blowing slag, and ensures the cleanliness of the inside of the central warehouse 1.

[0079] Furthermore, the driving mechanism 14 includes a driving motor 141, a rotating block 142 and a first ring 127. The first ring 127 is fixed to the bottom end of the vertical mounting rod 126. The driving motor 141 is fixed to the end of the first ring 127 away from the Y-shaped rod 123. The rotating block 142 is arranged at the end of the first ring 127 close to the Y-shaped rod 123 and the rotating block 142 is connected to the driving motor 141 in transmission. One end of the bending rod 143 is fixed to the arc surface of the rotating block 142, and the other end is fixed to a side close to the arc slide rod 124 with a toggle rod 144. The second ring 128 is rotatably sleeved on the toggle rod 144, and the end of the arc swing rod 125 is fixed to the arc side surface of the second ring 128.

[0080] In this embodiment, the drive motor 141 can be controlled to start and stop through a PLC control system, and the drive motor 141 is a high-temperature resistant motor that can effectively adapt to the working environment in the central warehouse 1.

[0081] The cam 142 is connected to the drive motor 141 to move the cleaning rod 143 in a reciprocating motion so that the cleaning rod 143 can be moved back and forth to move the cleaning rod 13 in a reciprocating motion.

[0082] The working principle of the present invention is as follows: by air quenching the blowing slag, that is, by introducing high-pressure gas and purified water into the central bin 1, the liquid blowing slag is cooled and solidified, and then the dust generated is collected and processed in a centralized manner through the provision of dust removal pipelines and dust removal devices, thereby minimizing the emission and diffusion of dust generated during the air quenching process and effectively reducing pollution to the environment. At the same time, through the provision of a discharge pipeline, the mud and solid particles are separated and sent to the corresponding subsequent processing processes, which can not only improve the utilization rate of raw materials, but also further reduce pollution to the environment and reduce waste.

[0083] The arrangement of the air inlet and water inlet pipelines enables secondary cooling of the blown slag particles in the central bin 1 while simultaneously carrying out air quenching, thereby reducing the outlet temperature, facilitating collection for subsequent unloading management, and effectively improving collection efficiency. The arrangement of two atomizing water pumps, one of which serves as a backup, can effectively improve the fault tolerance of the water inlet atomization step. When a larger flow rate is required, the two atomizing water pumps can also be started simultaneously, thereby achieving efficient cooling of the interior of the central bin 1 and improving work safety.

[0084] By setting up the arc-shaped guide plate 104, it is convenient for the blowing slag particles to further stay and be cooled, and it is also convenient to introduce the blowing slag particles into the outlet of the central warehouse 1, which is convenient for the transportation mechanism 2 6 to collect and process them. At the same time, the arc-shaped structure of the arc-shaped guide plate 104 can further guide the blowing slag particles to prevent them from scattering; and, by setting up the complex cleaning mechanism 12, it can effectively adapt to the shape of the arc-shaped guide plate 104 to clean the arc-shaped guide plate 104, prevent the blowing slag particles from staying on the arc-shaped guide plate 104, and increase the discharge rate of the blowing slag air quenching.
