Description

Technical Field

[0001] The invention relates to the technical field of metal smelting, and in particular to a side-blown furnace for refining slag at a low cost. Background Art

[0002] The power material side-blowing furnace is a natural gas furnace, which is significantly different from the conventional tuyere side-blowing furnace in terms of fuel use and furnace structure. The natural gas furnace is significantly better than the conventional tuyere furnace in terms of energy saving and consumption reduction, but at the same time, due to the difference in smelting process, the slag content of reduced lead is higher, and more refined slag is produced after preliminary pyro-refining; the refined slag produced in the refining process of power materials can be recycled and reused to maximize the recycling of useful substances in it. This practice not only helps to save resources and protect the environment, but also brings significant economic benefits.

[0003] Patent document with patent number CN115449589A discloses a composite furnace combining oxygen-enriched bottom blowing and side blowing, including a furnace body, a bottom oxygen gun socket, a side oxygen gun socket, a bottom oxygen gun and a side oxygen gun, a furnace chamber is built in the furnace body, the furnace chamber includes a material melting zone and a metal precipitation zone distributed in a step shape, and a concave precipitation tank is arranged at the bottom of the metal precipitation zone; at least one bottom oxygen gun socket is provided on the furnace body corresponding to the material melting zone; at least one side oxygen gun socket is provided on the furnace body corresponding to the metal precipitation zone; the bottom oxygen gun is correspondingly assembled in the bottom oxygen gun socket; the side oxygen gun is correspondingly assembled in the side oxygen gun socket; the angle between the axis direction of the side oxygen gun socket and the vertical direction is greater than the angle between the axis direction of the bottom oxygen gun socket and the vertical direction. The present application can adjust the arrangement position and form of the oxygen gun according to the composition of the melt in different regions, thereby improving the smelting effect and reducing the metal content in the slag.

[0004] However, in the actual production process, the inventors found that due to the bottleneck of the existing refined slag return furnace production process, when the side-blown furnace is used for reduction refining, more fuel is needed to maintain the furnace temperature, and more oxygen, charcoal and coke particles are needed to reduce the lead sulfide and lead oxide in the refined slag, which leads to high costs for returning the refined slag to the furnace for reuse, and more carbon emissions, and environmental risks. Therefore, the refined slag is usually sold to the outside, which involves the risk of hazardous waste transfer documents and environmental risks. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art. By setting a preheating furnace with an introduction component and an introduction mechanism, the raw materials are preheated and enter the reactor body or the side-blowing furnace mechanism for reaction, so as to avoid the added raw materials affecting the temperature in the furnace and the reaction effect. The raw materials react in steps in the reactor body and the side-blowing furnace mechanism, reducing the amount of fuel, oxygen, aromatic carbon and coke particles. At the same time, during the reaction process, the scattering mechanism and scattering components are used to scatter the refined slag melt from top to bottom, thereby improving the reaction efficiency and heat transfer efficiency, so that the refined slag melt reacts completely and avoids excessive temperature in the furnace.

At the same time, with the assistance of the J-shaped guide plate 335, the refined slag melt in the preheating furnace 32 can be guided into the reaction furnace body 31 as the side-blowing furnace mechanism 2 rotates, and the raw materials can be turned over for easy preheating.

[0042] In detail, when the control component 44 presses the first control rod 42 to move, the first sealing plate 41 and the second sealing plate 331 are controlled to open the first connecting port 311 and the second connecting port 321 respectively at the same time, and the first elastic member 43 is deformed; when the control component 44 does not press the first control rod 42, the first elastic member recovers the deformation to force the first control rod 42 to reset, thereby controlling the first sealing plate 41 and the second sealing plate 331 to automatically close the first connecting port 311 and the second connecting port 321 respectively; when the side-blowing furnace mechanism 2 rotates, the raw material enters the J-shaped guide plate 335 through the upper end of the J-shaped guide plate 335. After entering the bottom, it flows out from the bottom of the J-shaped guide plate 335 to turn the raw materials over; when the preheated and melted refined slag melt enters the bottom of the J-shaped guide plate 335, the control component 44 presses the second control rod 333 to move, the first control third sealing plate 332 opens the third connecting port 322, the second elastic member 334 is deformed, and then the refined slag melt is guided into the reactor body 31 through the J-shaped guide plate 335; when the control component 44 does not press the second control rod 333, the second elastic member 334 restores the deformation and forces the second control rod 333 to reset, thereby controlling the third sealing plate 332 to automatically close the third connecting port 322.

[0044] Further, if Figure 2 as well as Fig.10 As shown, the control assembly 44 includes a control frame 441 whose middle part is rotatably arranged on the sealing cover 24 and one end is used to press the first control rod 42 to move and the other end is used to press the second control rod 333 to move, and a driving member 442 arranged on the sealing cover 24 and used to drive the control frame 441 to rotate in both directions.

[0045] In this embodiment, the driving member 442 is provided to control the bidirectional rotation of the control frame 441, so as to respectively control the movement of the first control rod 42 and the second control rod 333.

[0049] In detail, when the first hopper 51 rotates downward with the side-blowing furnace mechanism 2, the opening and closing component 52 controls the first hopper 51 to open and scoop up the refined slag melt. When the first hopper 51 rotates downward with the side-blowing furnace mechanism 2, the opening and closing component 52 controls the first hopper 51 to close. Until the first hopper 51 rotates to the top of the reactor body 31, the opening and closing component 52 controls the first hopper 51 to open, and the refined slag melt is scattered onto the outer wall just above the reactor body 31, and then the refined slag melt is scattered and flows down from both sides of the reactor body, thereby improving the scattering effect and the heat transfer effect.

[0052] In this embodiment, a counterweight block 525 is provided to force the locking block 522 to rotate with the rotation of the side-blowing furnace mechanism 2 under the action of gravity, so that during the rotation of the side-blowing furnace mechanism 2, the locking rod 526 slides into the annular locking groove 523 or the sliding groove 524, so that the opening and closing cover 521 can be slid open or closed in the upper and lower positions respectively, thereby realizing the control of the opening and closing of the first hopper 51 in the upper and lower positions. The structure is simple and ingenious, the cost is low, and the operation is stable in a high temperature environment.

[0053] In detail, when the first hopper 51 rotates downward with the side-blowing furnace mechanism 2, the locking block 522 rotates under the action of the counterweight block 525, and the locking rod 526 is able to abut against the outer wall of the locking block 522 to lock the opening and closing cover 521 in an open state, so that the refined slag melt can be scooped in during the downward rotation of the first hopper 51, until the first hopper 51 is located directly below the reactor body 31, the opening and closing cover 521 slides into a sliding groove 524 under the action of gravity to close the first hopper 51; when the first hopper 51 rotates upward with the side-blowing furnace mechanism 2, the locking block 522 rotates under the action of the counterweight block 525, and the locking rod 526 is slidably connected to the annular locking groove 523 to lock the opening and closing cover 521 in a closed state, until the first hopper 51 is located directly above the reactor body 31, the opening and closing cover 521 slides into another sliding groove 524 under the action of gravity to open the first hopper 51.

[0054] It should be noted that the opening and closing cover 521 is slidably connected to both sides of the hopper, and correspondingly, there are two locking blocks 522, which improves the stability of the connection and the stability of the locking; in addition, the opening and closing cover 521 is raised on one side close to the first hopper 51, thereby guiding the refined slag melt in the first hopper 51 to scatter from all sides of the opening and closing cover 521, achieving complete discharge with a good scattering effect.

[0055] Further, if Figure 4-Figure 5 as well as Figure 10-11 As shown, the scattering assembly 34 includes a mounting rod 341 arranged in the reactor body 31, a plurality of second hoppers 342 arranged on the mounting rod 341 at equal intervals along the circumference of the reactor body 31, and a plurality of guide plates 343 arranged at intervals at the openings of the second hoppers 342 and used to guide the scattering of the refined slag molten liquid.

[0056] In this embodiment, the second hopper 342 is provided to scoop up the refined slag melt at the bottom of the reactor body 31 , and then the guide plate 343 is used to guide the scooped refined slag melt to scatter downward.

[0057] In detail, when the reactor body 31 rotates until the second hopper 342 is located below, the refined slag melt in the reactor body 31 is able to enter the second hopper 342. When the reactor body 31 continues to rotate, the second hopper 342 rotates upward to scoop up the refined slag melt until the second hopper 342 rotates upward to a certain inclination angle, and the refined slag melt therein is dispersed and flows out under the guidance of multiple guide plates 343.

[0058] It should be noted that a baffle 344 is provided at the opening of the second hopper 342 for preventing the refined slag melt from easily flowing out, thereby preventing the refined slag melt from flowing out when the first hopper 51 is rotated at a small angle, thereby increasing the height of the refined slag melt when it flows out and improving the scattering effect; in addition, the first hopper 51 and the second hopper 342 are provided with multiple ones along the length direction of the side-blowing furnace mechanism 2 to improve the scattering effect of the refined slag melt.

[0059] Further, if Figure 2 , Figure 7 as well as Fig.11 As shown, the heating mechanism 6 includes a plurality of conveying pipes 61 which are evenly spaced along the circumference of the side-blowing furnace mechanism 2 on the outer wall of the reaction furnace body 31 and extend to the outside of the side-blowing furnace mechanism 2, a first nozzle 62 which is arranged on the conveying pipe 61 and faces away from the reaction furnace body 31, and a second nozzle 63 which is arranged on the conveying pipe 61 and faces the preheating furnace 32.

[0060] In this embodiment, a first nozzle 62 is provided to spray and burn the fuel in the delivery pipe 61 to heat the interior of the side-blowing furnace mechanism 2 to maintain the reaction temperature, and at the same time, a second nozzle 63 is used to spray and burn the fuel to directly and quickly heat the preheating furnace 32, thereby improving the efficiency and effect of preheating and preventing the low temperature at the preheating furnace 32 from affecting the reaction temperature in the side-blowing furnace mechanism 2.

[0061] It should be noted that the first nozzle 62 and the second nozzle 63 themselves and the installation method are both existing technologies and will not be described in detail here.

[0062] Further, if Figure 2 as well as Figure 7 As shown, the inlet mechanism 7 includes a plurality of vent pipes 71 which are evenly spaced along the circumference of the side-blowing furnace mechanism 2 on the outer wall and extend to the outside of the side-blowing furnace mechanism 2, a plurality of air holes 72 which are spaced apart on the vent pipes 71, and an exhaust pipe 73 which is arranged on the side-blowing furnace mechanism 2 and sleeved on the outside of the vent pipes 71.

[0063] In this embodiment, by arranging the exhaust pipe 73 to be sleeved on the outside of the ventilation pipe 71, the exhaust gas discharged through the exhaust pipe 73 can heat the ventilation pipe 71 and the oxygen therein, thereby improving the utilization rate of thermal energy and reducing costs.

[0064] It should be noted that the exhaust ports of the air holes 72 and the exhaust pipe 73 are all facing the reactor body 31, so that the reactor body 31 blocks the air holes 72 and the exhaust pipe 73 to prevent the refined slag molten liquid from flowing in and leaking out; in addition, the conveying pipe 61, the ventilation pipe 71 and the exhaust pipe 73 are respectively connected to two external gas transmission systems and a collection system through a rotating joint. The rotating joint, the gas transmission system and the collection system themselves and the installation method are all existing technologies, which are not drawn in the drawings and will not be described in detail here.

[0065] Working process: First, the side-blowing furnace mechanism 2, the reaction furnace body 31 and the preheating furnace 32 are heated by the heating mechanism 6, and the refined slag raw material is fed into the preheating furnace 32 through the feed port 22 for preheating and melting, and then the introduction component 33 is used to introduce the refined slag melt into the reaction furnace body 31; Next, the aromatic carbon and coke particles are put into the preheating furnace 32 for preheating, and at the same time, the scattering assembly 34 rotates with the side-blowing furnace mechanism 2 to force the refined slag melt in the reaction furnace body 31 to scatter from top to bottom for preliminary reaction; Then, the refined slag melt and the preheated aromatic carbon and coke particles in the reactor body 31 are introduced into the side-blowing furnace mechanism 2 through the introduction mechanism 4, and the subsequent reaction is carried out in conjunction with the oxygen introduced by the introduction mechanism 7; Finally, the scattering mechanism 5 rotates with the side-blowing furnace mechanism 2 to force the refined slag melt, aromatic carbon and coke particles in the side-blowing furnace mechanism 2 to scatter from top to bottom onto the outer wall of the reaction furnace body 31 to achieve complete reaction.
