Technical Field

[0001] This invention relates to the field of smelting equipment technology, specifically to a rapid slag removal device for antimony metal smelting blast furnace. Background Technology

[0002] With the rapid development of the world economy and technology, the application fields of antimony are becoming increasingly broad. It is widely used in the production of various flame retardants, alloys, enamel, glass, rubber, coatings, pigments, plastics, semiconductor components, fireworks, pharmaceuticals, and other products. However, with the mining and smelting of antimony ore, my country's high-quality antimony ore resources are gradually decreasing, while the resources of various antimony smelting slags are constantly increasing. In the Xikuangshan area alone, the newly generated antimony smelting slag reaches as high as 15,000 tons annually.

[0003] In antimony metal smelting, blast furnace smelting is a commonly used process. The smelting process generates a large amount of slag, and timely and efficient slag removal is crucial for maintaining stable blast furnace operation, improving production efficiency, and reducing energy consumption. However, traditional slag removal equipment for antimony metal smelting blast furnaces has many problems. For example, the slag outlet structure is poorly designed, resulting in slow slag discharge and easy slag accumulation inside the furnace, affecting the normal progress of the smelting reaction. Some slag removal equipment relies on manual operation, which is labor-intensive and has low slag removal efficiency. Some equipment cannot effectively process the slag during the slag removal process, leading to difficulties in subsequent slag transportation and reuse. Furthermore, existing equipment is difficult to adapt to slag removal requirements under different working conditions, exhibiting poor flexibility. To address these problems, a rapid slag removal device for antimony metal smelting blast furnaces is proposed. Summary of the Invention

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] 1. This invention utilizes an inclined main channel in conjunction with a venturi tube and an accelerating branch pipe in the slag discharge assembly. By using high-pressure gas inside the furnace to form a booster airflow, the flow velocity of the slag within the channel is significantly increased. This design greatly shortens the slag discharge time, improves slag discharge efficiency, avoids slag accumulation inside the furnace, ensures the continuity and stability of the smelting process, solves the problem of slow slag discharge caused by unreasonable traditional slag outlet design, reduces the impact of slag accumulation on the smelting reaction, and uses high-pressure gas inside the furnace to boost the slag. This not only improves the slag discharge effect but also makes better use of existing energy, avoids the waste of external energy, and improves energy utilization efficiency.

[0017] 2. The feeding component of this invention automatically feeds materials by driving the vibrating bucket with a vibrating motor, adjusting the feeding position with an electric push rod, and controlling the opening and closing of the baffle with an electric telescopic rod, thus realizing automated feeding; the slag discharge component controls the opening and closing of the sealing plate with an opening and closing motor, eliminating the need for manual operation and reducing labor intensity.

[0018] 3. The waste residue treatment component of this invention integrates crushing and spraying functions. The drive motor moves the crushing tooth plate up and down to crush large pieces of waste residue, reducing its volume and facilitating subsequent discharge and further treatment, thus improving the waste residue treatment efficiency. The spray pipe sprays water through the spray head to cool or reduce dust, effectively suppressing the problem of dust flying in the waste residue.

[0036] In the description of this invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0038] Example 1

[0039] Reference Figure 1 - Figure 11As shown, a rapid slag removal device for antimony metal smelting in a blast furnace includes a base plate 1. A furnace body 2 is fixedly connected to the upper center of the base plate 1. A feeding component 13 is arranged on the upper surface of the base plate 1 on the left side of the furnace body 2, and a waste slag treatment component 14 is arranged on the upper surface of the base plate 1 on the right side of the furnace body 2. A waste slag collection frame 15 is arranged on the upper surface of the base plate 1 to the right of the waste slag treatment component 14. A liquid metal discharge pipe 9 is fixedly connected to the lower left end of the furnace body 2, and a waste slag discharge pipe 10 is fixedly connected to the lower right end of the furnace body 2. A slag discharge component 12 is arranged at the right end of the waste slag discharge pipe 10. The height of the waste slag discharge pipe 10 relative to the bottom surface of the furnace body 2 is... The height of the liquid metal pipe 9 relative to the bottom surface of the furnace body 2 is higher than that of the liquid metal pipe 9. This design is because during the antimony smelting process, the metal and slag will separate into layers. The slag has a lower specific gravity and will float on the surface of the liquid metal. By setting the slag outlet at a high position, it can be ensured that the slag will be discharged smoothly without mixing with the metal, thus avoiding affecting the purity of the metal. A high-temperature resistant air inlet pipe 11 for gas introduction is fixedly connected to the lower rear side of the furnace body 2. During the blast furnace smelting process, air or oxygen-enriched gas is usually sent into the furnace through blast equipment (such as tuyeres). These gases react with the raw materials in the furnace, thereby generating high temperature and pressure.

[0040] Furthermore, a furnace cover 3 is fixedly connected to the top of the furnace body 2. A waste gas outlet 4 is provided at the middle of the top of the furnace cover 3. The furnace cover 3 serves to seal the furnace body 2, preventing heat loss from the furnace and improving energy utilization efficiency. At the same time, it provides an installation position for the waste gas outlet 4, facilitating the centralized discharge and treatment of waste gas and reducing environmental pollution. A feed pipe 5 is provided on the upper left side of the furnace body 2. A baffle 6 is slidably connected inside the feed pipe 5. Electric telescopic rods 7 are fixedly connected to both the front and rear sides of the feed pipe 5. The output ends of the two sets of electric telescopic rods 7 are fixedly connected to the front and rear sides of the upper end of the baffle 6, respectively. A high-temperature resistant ultrasonic liquid level sensor 8 is fixedly installed on the left side of the furnace body 2 above the liquid metal discharge pipe 9. It is worth noting that this device is also equipped with a controller (not shown) to regulate the device. Due to the stratification of metal and slag during the antimony smelting process, the high-temperature resistant ultrasonic liquid level sensor 8 can work normally in a high-temperature environment and transmit the liquid level information to the controller in a timely manner, providing an accurate basis for the start of the slag discharge assembly 12 and avoiding slag overflow or untimely slag discharge.

[0041] Implementation 2

[0042] Furthermore, the slag discharge assembly 12 includes an inclined main channel 1201, which is rigidly connected to the waste slag discharge pipe 10 via a flange. A connecting branch pipe 1202 is fixedly connected to the upper right side of the inclined main channel 1201. A venturi tube 1203 is fixedly connected to the upper end of the connecting branch pipe 1202. An acceleration branch pipe 1204 is fixedly connected to the upper end of the venturi tube 1203 via a flange. The end of the acceleration branch pipe 1204 passes through the right side wall of the furnace body 2 and communicates with the interior of the furnace body 2. The inlet end of the acceleration branch pipe 1204 is connected to the high-pressure gas chamber of the furnace body 2 via a high-temperature resistant metal hose. In addition, a filter structure is provided at the end of the acceleration branch pipe 1204 to intercept high-temperature slag and other impurities in the furnace and protect the acceleration branch pipe 1204. 04. The Venturi tube 1203 and connecting branch pipe 1202, and the inclined main channel 1201 are arranged at an overall inclination of 15°-30° (optimal angle 20°, taking into account flow velocity and energy consumption). The acceleration branch pipe 1204 forms an acute angle of 30°-60° (preferably 45°) with the axis of the inclined main channel 1201, ensuring that when the high-pressure gas enters the inclined main channel 1201, it generates thrust along the slag flow direction, avoiding reverse airflow from hindering slag flow. The inclination angle of the acceleration branch pipe 1204 and the position design of the Venturi tube 1203 make the gas injection direction form a "boost angle" with the slag flow direction. The impact force of the airflow on the slag is decomposed into axial thrust and radial diffusion force, which both accelerates the flow velocity and avoids channel wear caused by local scouring.

[0043] Furthermore, a fixed base 1205 is fixedly connected to the right side of the connecting branch pipe 1202 above the inclined main channel 1201. A sealing plate 1206 for closing the inclined main channel 1201 is rotatably connected to the right side of the fixed base 1205. An opening and closing motor 1207 for driving the sealing plate 1206 to rotate is fixedly installed on the left side of the fixed base 1205. An annular baffle 1208 for limiting the sealing plate 1206 is fixedly connected to the rear right side of the inclined main channel 1201. When slag discharge is not required, the sealing plate 1206 closes the channel to prevent gas leakage and accidental slag flow. When slag discharge is required, the opening and closing motor 1207 drives the sealing plate 1206 to rotate and open the channel, realizing automated control of the slag discharge operation. Figure 5 As shown, when the sealing plate 1206 rotates clockwise, the inclined main channel 1201 is opened. The annular baffle 1208 positions the rotation of the sealing plate 1206 to prevent excessive rotation from causing seal failure. By controlling the forward and reverse rotation of the opening and closing motor 1207, the sealing plate 1206 can be opened and closed, and the slag discharge time and process can be precisely controlled.

[0044] Example 3

[0045] Furthermore, the feeding assembly 13 includes a first support frame 1301. The bottom of the first support frame 1301 is fixedly connected to the upper surface of the substrate 1 and located on the left side of the furnace body 2. A metal flow channel 1302 is fixedly connected inside the first support frame 1301. The metal flow channel 1302 is set with the left side lower than the right side, and the right end is located directly below the liquid metal pipe 9. A fixing frame 1303 is fixedly connected above the first support frame 1301. The right end of the metal flow channel 1302 is located directly below the liquid metal pipe 9. This design facilitates the smooth flow of liquid metal into the metal flow channel 1302 after it is discharged from the liquid metal pipe 9 for collection and subsequent processing, thus realizing the initial collection and transportation of metal.

[0046] Furthermore, two sets of movable guide rails 1304 are fixedly connected to the top of the fixed frame 1303. A support frame 1305 is slidably connected above the two sets of movable guide rails 1304 via sliding blocks. An electric push rod 1311 is fixedly connected to the middle left side of the fixed frame 1303. The output end of the electric push rod 1311 is fixedly connected to the crossbeam in the middle of the support frame 1305. The movable guide rails 1304 provide precise guidance for the horizontal movement of the support frame 1305, ensuring that the support frame 1305 can move smoothly and accurately, thereby adjusting the alignment position of the discharge port of the vibrating bucket 1309 and the feed pipe 5 of the furnace body 2. As the support structure for the feed hopper 1306 and the vibrating bucket 1309, the support frame 1305 can slide along the movable guide rails 1304 under the push of the electric push rod 1311 to realize the adjustment of the feeding position.

[0047] Furthermore, a feed hopper 1306 is fixedly connected above the support frame 1305, and four sets of supports 1307 are fixedly connected inside the support frame 1305. A buffer 1308 is fixedly connected above each of the four sets of supports 1307, and a vibrating bucket 1309 is fixedly connected between the four sets of buffers 1308. The vibrating bucket 1309 is located directly below the feed hopper 1306, and the discharge port of the vibrating bucket 1309 is correspondingly set with the feed pipe 5. Vibrating motors 1310 are fixedly connected to the middle of the front and rear sides of the vibrating bucket 1309. The buffers 1308 can reduce the impact of the vibrating bucket 1309 on the support frame 1305 when it vibrates, reduce the vibration and noise of the equipment, ensure the stability of the feeding process, and extend the service life of the equipment.

[0048] Example 4

[0049] Furthermore, the waste residue treatment component 14 includes a second support frame 1401 and a centrifugal water pump 1407. The second support frame 1401 is fixedly connected to the upper surface of the base plate 1 and located on the right side of the furnace body 2. The centrifugal water pump 1407 is fixedly installed on the upper surface of the base plate 1 and located in front of the second support frame 1401. Two L-shaped support plates 1402 are fixedly connected above the second support frame 1401. A waste residue flow channel 1403 is fixedly connected between the two support plates 1402. The waste residue flow channel 1403 is set with a high left side, a flat middle side, and a low right side. This design of a high left side, a flat middle side, and a low right side utilizes the gravity of the waste residue itself to allow the waste residue to flow smoothly along the waste residue flow channel 1403, reducing energy consumption. At the same time, the flat middle section can ensure that the waste residue has sufficient residence time in the flow channel for crushing and cooling. The centrifugal water pump 1407 provides water for the cooling and dust suppression of the waste residue and is an important power equipment in the waste residue treatment process.

[0050] Furthermore, fixing strips 1404 are fixedly connected to the upper right side of both support plates 1402. Spray pipes 1405 are fixedly connected between the two sets of fixing strips 1404. At least five spray heads 1406 are fixedly connected to the bottom of the spray pipes 1405. A connecting hose 1408 is fixedly connected to the front end of the spray pipes 1405 through a connector. The end of the connecting hose 1408 is fixedly connected to the output end of the centrifugal water pump 1407. The spray heads 1406 can expand the spray range to ensure that the waste residue can be fully sprayed during the flow process, thereby improving the cooling and dust reduction effect.

[0051] Furthermore, guide rods 1409 are slidably connected to the middle of both support plates 1402 via sliding sleeves. Mounting plates 1410 are fixedly connected above the two guide rods 1409. Crushing tooth plates 1418 are fixedly connected to the bottom of the mounting plates 1410. Connecting seats 1411 are fixedly connected to the bottom of both support plates 1402. A rotating shaft 1412 is rotatably connected between the two sets of connecting seats 1411. A driven wheel 1413 is fixedly connected to the middle of the rotating shaft 1412. Both ends of the rotating shaft 1412 pass through the sides of the corresponding connecting seats 1411 and are fixedly connected to rotating plates 1416. The ends of the two rotating plates 1416 furthest from the rotating shaft 1412 are rotatably connected to cranks 1417. The upper ends of the two connecting cranks 1417 are respectively connected to the two guide rods via hinges. The bottom of 1409 is rotatably connected, and the drive motor 1414 is fixedly installed inside the second support frame 1401. The output end of the drive motor 1414 is fixedly connected to the drive wheel 1415. The drive wheel 1415 is connected to the driven wheel 1413 through a synchronous belt. The crushing tooth plate 1418 moves up and down with the mounting plate 1410 to repeatedly impact and crush the waste residue. The crushing tooth plate 1418 crushes large pieces of waste residue into small pieces, which facilitates subsequent cooling, dust reduction and collection, and improves the efficiency and quality of waste residue treatment. The guide rod 1409 slides up and down along the support plate 1402 under the drive of the drive motor 1414, providing precise guidance for the up and down movement of the mounting plate 1410 and the crushing tooth plate 1418, ensuring that the crushing tooth plate 1418 can accurately impact and crush the waste residue.

[0052] The working principle of this device is as follows: First, the electric push rod 1311 on the fixed frame 1303 extends and retracts, pushing the support frame 1305 to slide along the moving guide rail 1304, adjusting the alignment position of the discharge port of the vibrating bucket 1309 with the feed pipe 5 of the furnace body 2, ensuring that the raw material accurately enters the furnace body 2. The antimony ore raw material mixed with coke is fed into the feed hopper 1306 through the external Z-shaped conveyor belt and then enters the vibrating bucket 1309. The vibration motors 1310 on the front and rear sides of the vibrating bucket 1309 are started, driving the vibrating bucket 1309 to vibrate, so that the raw material falls evenly. Four sets of buffers 1308 To reduce the impact of vibration on the support frame 1305 and ensure stable feeding, the electric telescopic rod 7 extends and retracts to drive the baffle 6 to slide up and down in the feed pipe 5, controlling the opening and closing of the feed pipe 5 and the amount of feed, avoiding excessive input of raw materials that would affect smelting efficiency. The furnace body 2 is supplied with combustion gas through the air inlet pipe 11, so that the raw materials in the furnace are smelted at high temperature. The waste gas generated during smelting is discharged through the waste gas outlet 4 on the furnace cover 3 for subsequent treatment. After smelting, the liquid metal has a high density and settles at the bottom of the furnace body 2. It is discharged from the liquid metal outlet pipe 9 at a lower position and collected along the metal flow channel 1302.The waste residue has a low density and floats above the liquid metal. It is discharged from the waste residue discharge pipe 10 at a higher position, achieving stratified separation of metal and waste residue. The high-temperature resistant ultrasonic liquid level sensor 8 on the left side of the furnace body 2 monitors the liquid level of the waste residue in real time. When the liquid level reaches the preset value, the monitored information is transmitted to the external controller. The controller controls the slag discharge assembly 12 to work. The opening and closing motor 1207 drives the sealing plate 1206 to rotate around the fixed seat 1205, opening the outlet of the inclined main channel 1201. The high-pressure gas in the furnace enters the Venturi tube 1203 through the acceleration branch pipe 1204. 203 utilizes the "throttling effect" to convert gas kinetic energy into pressure energy. A high-speed airflow is injected into the inclined main channel 1201 through the connecting branch pipe 1202. The airflow forms a 45° acute angle with the waste residue flow direction, generating axial thrust and accelerating the waste residue to flow to the right along the inclined main channel 1201, preventing waste residue stagnation. Under the combined effect of its own gravity and the airflow's propulsion, the waste residue quickly enters the waste residue treatment component 14 from the inclined main channel 1201, achieving efficient slag discharge. The waste residue then enters the waste residue flow channel 1403 from the inclined main channel 1201. The waste residue flow channel 1403 is "left-right". The waste residue is transported by gravity using a "high side, flat middle, low right side" configuration. The drive motor 1414 starts, driving the driven wheel 1413 and rotating shaft 1412 via the drive wheel 1415 and synchronous belt. The rotating plates 1416 at both ends of the rotating shaft 1412 rotate synchronously, pushing the guide rod 1409 up and down along the support plate 1402 via the connecting crank 1417. This causes the crushing toothed plate 1418 at the bottom of the mounting plate 1410 to repeatedly impact the waste residue, breaking large pieces into smaller ones. The input end of the centrifugal water pump 1407 is connected to an external water source via a pipeline to supply water. The waste residue is pumped into the spray pipe 1405 through the connecting hose 1408 and evenly sprayed onto the crushed waste residue through at least five spray heads 1406 to achieve cooling and dust reduction, avoiding dust pollution. The treated waste residue flows into the waste residue collection frame 15 along the inclined section on the right side of the waste residue flow channel 1403, completing the collection for subsequent transportation and reuse. After the slag discharge is completed, the opening and closing motor 1207 drives the sealing plate 1206 to reset, closing the inclined main channel 1201; the feeding component 13 stops vibrating, the baffle 6 closes the feed pipe 5; the waste residue treatment component 14 stops working, waiting for the next smelting cycle.
