Description

Technical Field

[0001] The invention relates to the technical field of automatic feeding, and more specifically, to an automatic feeding system for a crude copper smelting furnace. Background Art

[0002] Blister copper, also known as blister copper, is the copper produced by blowing the matte containing about 80% copper produced in the previous process. After blowing in the blowing furnace (converter or flash blowing furnace), it contains about 98.5% copper. If it is necessary to remove the remaining impurities, the impurities are further oxidized through fire refining, and the copper is reduced to 99.2% to 99.7%. It can be cast into copper anodes for electrolytic refining, or cast into copper ingots for processing into plates, tubes, wires, strips and profiles. In the production and processing process, in order to refine the blister copper to obtain copper with higher purity, blister copper refining equipment is needed. In the blister copper refining equipment, in order to facilitate the loading of blister copper, a hopper and a conveyor belt are generally used for loading.

[0003] At present, most of the feeding equipment on the market directly pours the raw materials required for crude copper refining into the smelting furnace.

Specific embodiment one:

[0039] See also Figure 1-12 Structural schematic diagram, the present invention provides the following technical solutions:

[0040] Specifically, it refers to an automatic feeding system for a crude copper smelting furnace, including a base 1 and a smelting furnace 2 installed on the base 1. A feeding buffer structure 3 is provided on the base 1. The feeding buffer structure 3 can temporarily store raw materials that need to be introduced into the smelting furnace 2, so as to avoid the accumulation of raw materials caused by direct input of a large amount of raw materials into the smelting furnace 2, and to avoid further impact of the raw materials on the smelting furnace 2. A feeding buffer structure 4 is fixed on the base 1, which cooperates with the smelting furnace 2 and the discharge end of which extends to the inside of the smelting furnace 2.

[0041] The material discharge buffer structure 4 includes a fixed cylinder 401 fixed to the base 1 by bolts and coaxial with the smelting furnace 2, a rotating ring 402 is rotatably connected to the top of the fixed cylinder 401, a support frame 403 is fixed to the rotating ring 402, a slide plate 404 is slidably connected to the top of the support frame 403, and a lifting column 405 is fixed to the top of the slide plate 404. Under the coordinated action of the driving plate 415, the reciprocating screw 416, and the driving structure 417, the slide plate 404 can move radially while the rotating ring 402 rotates, and the buffer discharge pipe 407 rotates around the smelting furnace 2 and moves radially, so that the buffer discharge pipe 407 can move to different positions inside the smelting furnace 2, which is more conducive to the buffer discharge pipe 407 to accurately transport the raw materials to the specified position, and effectively avoid the accumulation of raw materials inside the smelting furnace 2.

[0042] A support plate 406 is fixed on the top of the lifting column 405. The lifting column 405 can adjust the height of the discharge end of the buffer discharge pipe 407 from the bottom of the smelting furnace during the loading process, reduce the discharge height, and thereby reduce the impact force of the raw materials on the inner wall of the smelting furnace 2. At the same time, the raw materials can be evenly introduced into the smelting furnace 2 layer by layer, so that the raw materials are evenly distributed inside the smelting furnace 2, avoiding the situation where a large amount of raw materials are accumulated due to loading at a fixed position, so that the raw materials inside the smelting furnace have a consistent melting rate when heated, thereby improving the melting efficiency, reducing the energy consumption of the smelting furnace, and being more energy-saving and environmentally friendly. The end of the support plate 406 away from the lifting column 405 is hinged with a buffer discharge pipe 407 that cooperates with the smelting furnace 2, and a receiving hopper 408 is fixed on the top of the buffer discharge pipe 407. A telescopic rod 409 is hinged on one side of the receiving hopper 408, and the end of the telescopic rod 409 away from the receiving hopper 408 is hinged on the support plate 406. Under the action of the telescopic rod 409, the buffer discharge pipe 407 can be tilted at a certain angle inside the smelting furnace, increasing the coverage area of ​​the buffer discharge pipe 407 inside the smelting furnace 2, so that the raw materials are more evenly distributed inside the smelting furnace 2 when the buffer discharge pipe 407 is loaded.

[0043] A first motor 411 is fixed to the outer circumference of the fixed cylinder 401 through a support plate 410, an annular rack 412 is fixed to the outer circumference of the rotating ring 402, and a driving gear meshing with the annular rack 412 is fixed to the output shaft end of the first motor 411; an annular guide bar 413 is fixed to the top of the fixed cylinder 401, and an annular guide groove 414 cooperating with the annular guide bar 413 is provided at the bottom of the rotating ring 402. The combination of the annular guide bar 413 and the annular guide groove 414 enables the rotating ring 402 to be fixed to the top of the fixed cylinder 401, ensuring the stability of the rotating ring 402 when it rotates and will not be separated from the top of the fixed cylinder 401.

[0044] A driving plate 415 penetrating the support frame 403 is fixed at the bottom of the slide plate 404, a reciprocating screw 416 drivingly connected to the driving plate 415 is installed at the top of the support frame 403, and a driving structure 417 drivingly connected to the reciprocating screw 416 is fixed on the support frame 403. The driving structure 417 is composed of a motor and a driving belt drivingly connected to the output shaft end of the motor, wherein the end of the driving belt away from the motor is drivingly connected to one end of the reciprocating screw 416.

[0045] A T-shaped slide groove is provided at the bottom of the slide plate 404 , a T-shaped slide bar matching with the T-shaped slide groove is fixed at the top of the support frame 403 , and a guide groove 418 matching with the driving plate 415 is provided at the top of the support frame 403 .

[0046] The working principle of the automatic feeding system of the crude copper smelting furnace provided by the present invention is as follows:

[0047] Working principle: When feeding the smelting furnace 2, the raw materials are first transported to the storage tank 303 through the conveyor belt and other equipment, and weighed through the weighing platform 301. When the transported raw materials reach the preset value, the raw materials are stopped, and the spiral conveying structure 306 located in the first discharge barrel 304 and the second discharge barrel 305 is opened to transport the raw materials in the storage tank 303 to the receiving hopper 408. After the receiving hopper 408 is filled with raw materials, the first motor 411 drives the rotating ring 402 to rotate, thereby driving the buffer discharge pipe 407 and the receiving hopper 408 installed thereon. The hopper 408 and the like rotate around the smelting furnace 2. During the rotation, the feeder 418 installed on the buffer feeder pipe 407 opens, and the raw materials are evenly distributed inside the smelting furnace 2 through the buffer feeder pipe 407. After the raw materials in the receiving hopper 408 are discharged, it moves back to the original position to continue receiving materials. After the raw materials are accumulated at the bottom of the smelting furnace 2 and around the wall, the buffer feeder pipe 407 is driven to rise by the lifting column 405, or the position of the discharge port of the buffer feeder pipe 407 inside the smelting furnace 2 is adjusted by the telescopic rod 409, so that the raw materials can be evenly distributed in the smelting furnace 2. The raw materials are evenly heated in the smelting furnace, so as to increase the smelting rate of the smelting furnace 2 for the raw materials and reduce the energy consumption. Specific embodiment 2:

[0049] Based on the specific embodiment 1, the difference of this embodiment is that:

[0050] like Figure 5-7 As shown, a flap discharger 418 is installed on the buffer discharge pipe 407 and near the receiving hopper 408. The buffer discharge pipe 407 includes a straight pipe section 4071 connected to the receiving hopper 408. The bottom end of the straight pipe section 4071 is a circular arc section 4072 facing the axial direction of the smelting furnace 2. The discharge port end of the circular arc section 4072 at the bottom of the buffer discharge pipe 407 is installed with a circular blocking cover 4073 with an opening facing away from the axial direction of the smelting furnace 2. By providing an arc section 4072 at the bottom of the straight pipe section 4071 in the buffer discharge pipe 407, the raw material that passes through the straight pipe section 4071 at high speed can change its movement direction and reduce its impact force. The raw material passing through the arc section 4072 impacts the circular blocking cover 4073, and after most of the impact force is eliminated, it falls into the smelting furnace 2 through the discharge end, thereby effectively reducing the impact of the raw material on the inner wall of the smelting furnace 2 during the loading process, thereby improving the protection effect on the smelting furnace 2 and extending the service life of the Yancheng smelting furnace 2. Specific embodiment three:

[0052] Based on the second specific embodiment, the difference of this embodiment is that:

[0053] like Figure 1 , 8 -10, the loading buffer structure 3 includes a weighing platform 301 slidably arranged on the base 1, a buffer rod 302 is fixed on the top of the weighing platform 301, a storage trough 303 is fixed on the top of the buffer rod 302, a first discharging cylinder 304 connected to the inner cavity of the storage trough 303 is fixed at the bottom of the storage trough 303, and a second discharging cylinder 305 connected to the first discharging cylinder 304 is fixed at the discharging end of the first discharging cylinder 304.

[0054] The first discharging barrel 304 and the second discharging barrel 305 are both equipped with a spiral conveying structure 306. The discharging end of the second discharging barrel 305 is equipped with a material guiding elbow 307. The discharging end of the material guiding elbow 307 is equipped with a material discharge hose 308 that cooperates with the receiving hopper 408. The material discharge hose 308 can cooperate with the receiving hopper 408 during the material discharge process and further absorb the impact of the raw materials. The spiral conveying structure 306 includes a second motor, and a conveying shaft with a spiral conveying fan blade is fixed to the output shaft end of the second motor.

[0055] The base 1 includes a support platform 101 and a plurality of support legs 102 fixed to the bottom edge of the support platform 101. A mounting tube 103 matching the smelting furnace 2 is passed through the support platform 101. An auxiliary heating strip 104 in contact with the bottom of the smelting furnace 2 is fixed to the bottom of the mounting tube 103. The auxiliary heating strip 104 can preheat the smelting furnace 2 before or when adding raw materials, thereby shortening the time for the smelting furnace 2 to heat and melt the raw materials, so as to improve the heating and melting efficiency of the smelting furnace 2.

[0056] The buffer rod 302 includes a spring sleeve fixedly connected to the weighing platform 301, an end cap is fixed on the top of the spring sleeve, a guide rod is passed through the end cap, the top of the guide rod is fixedly connected to the storage tank 303, and one end of the guide rod located inside the spring sleeve is fixed with a pressure plate that matches the inner cavity of the spring sleeve; wherein a spring is arranged inside the spring sleeve, one end of the spring is pressed against the bottom of the spring sleeve, and the other end of the spring is pressed against the pressure plate. The buffer rod 302 can buffer and absorb the impact when the raw material is transported to the storage tank 303, avoid generating large vibrations that are transmitted to external equipment, and improve the working environment and conditions of the feeding structure.

[0057] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
