[0002] The fuming furnace is a furnace that blasts coal powder into liquid slag to volatilize the valuable metals in the slag in the form of metals, oxides or sulfides, thereby achieving metal recovery and reuse. The fuming furnace was originally used to treat lead blast furnace slag, and was later widely used in non-ferrous metal smelting fields such as tin smelting slag. In the actual heating work of the fuming furnace, it is necessary to add coal powder in a quantitative manner to promote combustion. The liquid slag inside the fuming furnace will boil at high temperature and accelerate volatilization. The current fuming furnace feeding device needs to put coal powder on top of the material. The utilization rate of coal powder combustion is low. The method of directly blowing coal powder into the slag with a blower is easy to mix with the gas in the furnace, affecting the comprehensiveness of coal powder heating. A large amount of coal powder will be discharged by the exhaust system, resulting in large losses. At the same time, it is not convenient to automatically control the stopping of feeding.

[0040] In the disclosed embodiment, the rotary discharge member 4 includes: a rotating sleeve 401, a guide groove 4011, a discharge rod 402, a discharge port 4021, an electric heating wire 4022 and a buoyancy stop column 403. The rotating sleeve 401 is rotatably sleeved on the heat-conducting discharge pipe 101; a circle of guide grooves 4011 is provided on the rotating sleeve 401, and the circle of guide grooves 4011 are respectively inclined grooves; a discharge rod 402 is fixedly installed at the bottom of the rotating sleeve 401, and a discharge port 4021 is provided at the bottom of the discharge rod 402, and the two sides of the inside of the discharge port 4021 are respectively inclined structures; an electric heating wire 4022 is embedded at the bottom of the discharge rod 402; the buoyancy stop column 403 is located inside the discharge port 4021; the buoyancy stop The stop column 403 is used to close the discharge port 4021; the buoyancy stop column 403 is a ceramic pore structure; the buoyancy stop column 403 is used to float in the liquid material inside the fumigation furnace; the closed cleaning part 5 includes: a lifting connection frame 501, a stop ring 502, a lifting column 503, a closing plug 5031 and a cleaning brush 504, the lifting connection frame 501 is fixedly installed inside the heat-conducting discharge pipe 101; the stop ring 502 is fixedly installed inside the heat-conducting discharge pipe 101; the lifting column 503 is slidably sleeved on the lifting connection frame 501, and the closing plug 5031 is rotatably installed on the top of the lifting column 503; the closing plug 5031 is used to close the stop ring 502; the stop ring 502 and the closing plug 5031 are connected.

[0041] In the embodiment of the present disclosure, the boiling control member 6 includes: a lifting slide shaft 601, a connecting plate 602, a buoyancy ring 603, a one-way bearing 604, a control inner ring 605 and a toggle ball 606. Two lifting slide shafts 601 are provided, and the two lifting slide shafts 601 are respectively slidably mounted on the floating connecting frame 102; the bottom of the two lifting slide shafts 601 is fixedly mounted with a connecting plate 602; the bottom of the connecting plate 602 is fixedly mounted with a buoyancy ring 603; the outer ring of the one-way bearing 604 is fixedly sleeved on the connecting plate 60 2; the inner ring of the one-way bearing 604 is fixedly sleeved with a control inner ring 605; a circle of moving balls 606 are embedded in the inner ring of the control inner ring 605, and a circle of moving balls 606 are respectively rolled and attached to the inner side of a circle of guide grooves 4011; the buoyancy ring 603 is a hollow structure, and the buoyancy ring 603 is used to float on the liquid material inside the fuming furnace. The boiling control member 6 can be adapted to the liquid slag inside the fuming furnace, and can be attached to the liquid surface when the liquid slag inside the fuming furnace is boiling. The rising thrust of boiling gas pressure can be used to control the discharge rod 402 to rotate and discharge, which can improve the comprehensiveness of coal powder delivery and further improve the uniformity of slag combustion. The structure is simple to control and can automatically control the lifting and lowering according to the boiling degree. When the liquid slag boils, the buoyancy ring 603 can be pushed up. At this time, the one-way bearing 604 is in a locked state. The buoyancy ring 603 can be pushed up to drive the moving ball 606 on the inner ring 605 to move up, and the guide groove 4011 can be pushed up. , driving the rotating sleeve 401 to rotate, thereby controlling the rotation of the discharge rod 402. Because the lifting column 503 is rotatably connected to the closing plug 5031, when the discharge rod 402 rotates, the cleaning brush 504 will also drive the lifting column 503 to rotate on the closing plug 5031 without getting stuck. When the buoyancy ring 603 falls, the one-way bearing 604 is in a non-locked state and can automatically adapt to the rotation, ensuring that the discharge rod 402 can be controlled to rotate continuously as the slag boiling control of the buoyancy ring 603 rises and falls.

[0042] Embodiment 2, on the basis of embodiment 1, the reaction test piece 7 comprises: a fixed block 701 and a power-connecting spring piece 702, the fixed block 701 is fixedly mounted on the floating connection frame 102; the power-connecting spring piece 702 is fixedly mounted on the fixed block 701; the power-connecting spring piece 702 is located above the lifting slide shaft 601 on the same side; the particle isolation piece 8 comprises: an isolation mounting frame 801 and an electromagnet 802, the isolation mounting frame 801 is fixedly mounted inside the coal powder feeding pipe 1011; the electromagnet 802 is fixedly mounted on the isolation mounting frame 801; the particle isolation piece 8 also comprises: a stop The stop plate 803, the repelling electromagnet 8031 ​​and the closed tension spring 804, the stop plate 803 is located inside the coal powder feeding pipe 1011; the front end of the stop plate 803 is a slope structure; the back of the stop plate 803 is fixedly installed with the repelling electromagnet 8031, and the repelling electromagnet 8031 ​​is slidably installed on the isolation mounting frame 801; the electromagnet 802 is aligned with the repelling electromagnet 8031; the closed tension spring 804 is located outside the repelling electromagnet 8031; the end of the closed tension spring 804 is connected to the stop plate 803, and the other end of the closed tension spring 804 is connected to the isolation mounting frame 80 1; the electric spring piece 702, the lifting slide shaft 601, the repelling electromagnet 8031 ​​and the electromagnet 802 are electrically connected, and the reaction test piece 7 can automatically detect the reaction degree of coal powder and slag, which can avoid the problem of excessive combustion reaction caused by excessive coal powder. This structure ensures the quality of slag reaction and avoids excessive reaction. The structure control is direct and efficient, and the automatic control is performed at the same time. There is no need for manual operation, monitoring and observation. The particle isolation piece 8 can use magnetic force to quickly control the pause, which effectively improves the safety of the fuming furnace and avoids the indirectness of manual detection and observation. It is also easy to miss the problem, and manual control of feeding is required. The present structure can directly stop the coal powder feeding when excessive boiling occurs, to ensure that the boiling degree of the slag inside the fuming furnace is within a reasonable range. If the buoyancy ring 603 fluctuates greatly due to excessive boiling of the slag, the buoyancy ring 603 drives the lifting slide shaft 601 to touch the power-connected spring piece 702. At this time, the repelling electromagnet 8031 ​​and the electromagnet 802 are energized, causing repulsion, driving the stop plate 803 to close the end of the coal powder feed pipe 1011, thereby achieving temporary closure, thereby reducing the amount of coal powder added and reducing the degree of slag reaction.

[0043] The working principle of this embodiment is as follows: the heat-conducting discharge pipe 101 is pre-buried and installed inside the fuming furnace, one end of the coal powder feeding pipe 1011 on the heat-conducting discharge pipe 101 passes through the fuming furnace and is retained outside the fuming furnace, the coal powder connecting pipe 103 is externally connected to the coal powder hopper, and the feeding blower on the coal powder hopper externally connected to the coal powder connecting pipe 103 is started to realize the coal powder feeding work. At this time, the coal powder can be driven by the crushing motor 104 to drive the crushing impeller to rotate, and is crushed twice, and is pneumatically conveyed to the bottom of the fuming furnace through the heat-conducting discharge pipe 101. A row of diffusion covers 202 can make the coal powder be conveyed along the inner wall of the heat-conducting discharge pipe 101 to promote comprehensive heating and drying. During the process, the air pressure sealing ball 303 is closed at the inclined surface on the upper side of the stop ring 302 under the action of air pressure. When the conveying is completed, the air pressure acting on the air pressure sealing ball 303 disappears. At this time, the air pressure sealing ball 303 can fall and no longer close the stop ring 302. At this time, the stop ring 302 can play a role in discharging moisture to ensure dehumidification. Continuity, during the process, the coal powder inside the heat-conducting discharge pipe 101 can be continuously dried, and the air pressure of the heat-conducting discharge pipe 101 can push the closing plug 5031, lengthen the tension spring between the stop ring 502 and the closing plug 5031, and at the same time, the buoyancy stop column 403 will also move downward under the action of air pressure and separate from the discharge port 4021, and no longer be closed. After the coal powder is added once, the air pressure in the heat-conducting discharge pipe 101 disappears, and between the stop ring 502 and the closing plug 5031, the air pressure in the heat-conducting discharge pipe 101 disappears. The tension spring between them can pull the cleaning brush 504 upward, and at this time, the cleaning brush 504 can be driven to rise and brush the inner inclined surface of the discharge port 4021 to ensure that the inner inclined surface of the discharge port 4021 can be fully closed and fitted by the buoyancy stop column 403 below. The buoyancy stop column 403 below will also rise rapidly under the action of buoyancy to close the discharge port 4021. When the discharge port 4021 discharges the coal powder, the electric heating wire 4022 can continue to heat the coal powder to promote the combustion of the coal powder.

[0044] When the liquid slag is boiling, the buoyancy ring 603 can be pushed up. At this time, the one-way bearing 604 is in a locked state. The buoyancy ring 603 can be pushed up to drive the moving ball 606 on the inner ring 605 to move up, and the guide groove 4011 can be driven to rotate the rotating sleeve 401, thereby controlling the rotation of the discharge rod 402. When the buoyancy ring 603 falls, the one-way bearing 604 is in a non-locked state and can automatically adapt to the rotation to ensure that the discharge rod 402 can be controlled to rotate continuously in one direction as the slag boiling control of the buoyancy ring 603 rises and falls. When the pulverized coal feed pipe 1011 is fed, the closed tension spring 8 04 Under strong pulling, the stop plate 803 and the coal powder feed pipe 1011 are in a separated state, which will not affect the discharge of coal powder. If the buoyancy ring 603 fluctuates greatly due to excessive boiling of the slag, the buoyancy ring 603 drives the lifting slide shaft 601 to touch the power-connecting spring piece 702, and the circuit is in a pass state. At this time, the repulsion electromagnet 8031 ​​and the electromagnet 802 are energized and repulsion occurs. At this time, the repulsion electromagnet 8031 ​​slides outward on the isolation mounting frame 801, thereby driving the stop plate 803 to close the end of the coal powder feed pipe 1011, achieving temporary closure to reduce the input of coal powder and reduce the degree of slag combustion and boiling.
