Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0043] The defect of the ferrovanadium smelting furnace in the prior art is that the lean slag and bottom solution contained in the ferrovanadium raw material are difficult to fully contact and mix with the reducing agent powder on the surface, resulting in insufficient ferrovanadium smelting, thereby reducing the quality of the finished ferrovanadium smelting solution in the smelting furnace;
[0044] In order to solve the above problems, the main concept adopted in this embodiment is: a hydraulic cylinder 4 fixed on a support plate 3 outside the shell 2 of the ferrovanadium smelting furnace drives the drive assembly 7 and the feeding assembly 8 to move, so as to promote the solution in the furnace body 1 and the reducing agent powder to be fully contacted and mixed, thereby fully improving the smelting of ferrovanadium, and further improving the quality of the finished ferrovanadium smelting solution in the smelting furnace; wherein, during the swinging process of the furnace body 1, the fixing pins 5 on both sides of the furnace body 1 prevent the arc-shaped rack 6 from being misaligned with the drive assembly 7, causing the furnace body 1 to tip over, thereby reducing the risk of the furnace body 1 tipping over during operation.
[0045] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods;
[0046] The ferrovanadium smelting furnace provided by the present invention comprises a furnace body 1 and a shell 2, wherein the furnace body 1 is located in the shell 2; a feed port 11 is provided on the top of the furnace body 1; and further comprises:
[0047] A driving assembly 7; the driving assembly 7 is connected to the furnace body 1;
[0048] A material feeding component 8; the material feeding component 8 is fixedly connected to one side of the housing 2; and is used to provide reducing agent powder;
[0049] Support plate 3; the support plate 3 is fixedly connected to one side of the housing 2;
[0050] Hydraulic cylinder 4; the hydraulic cylinder 4 is fixed to the support plate 3 and is used to provide power;
[0051] Fixed pin 5; The furnace body 1 is fixedly connected with fixed pins 5 on both sides, and one end of the fixed pin 5 away from the furnace body 1 is rotatably connected to the shell 2;
[0052] The arc-shaped rack 6 is fixedly connected to the bottom of the furnace body 1; the arc-shaped rack 6 cooperates with the driving assembly 7 to drive the furnace body 1 to swing left and right;
[0053] The staff first puts the mixed charge into the furnace body 1, and heats and melts the mixed charge in the furnace body 1 through the electric heating element arranged in the furnace body 1; after the reaction starts, the remaining charge is added successively; after the charge is added, the feed port 11 is closed, and the hydraulic cylinder 4 is started at this time, and the hydraulic cylinder 4 drives the drive component 7 to move, and the drive component 7 cooperates with the meshing arc-shaped rack 6, thereby driving the furnace body 1 to swing; using the inertia of swinging, the molten solution of the charge in the furnace body 1 is constantly shaken, thereby driving the unmelted charge to absorb heat, accelerating the melting of the charge, and increasing the melting rate of the charge; during the swinging process of the furnace body 1, the fixing pins 5 on both sides of the furnace body 1 avoid the misalignment of the arc-shaped rack 6 and the drive component 7, and at the same time reduce the pressure of the furnace body on the load-bearing plate 71, thereby increasing the swinging rate of the furnace body, and further improving the effect of fully stirring the solution in the furnace body;
[0054] While the hydraulic cylinder 4 drives the driving component 7 to move, the driving component 7 squeezes the feeding component 8, and uses the pressure of the driving component 7 on the feeding component 8 to transport the reducing agent in the feeding component 8 into the furnace body 1, so that the swinging solution and the reducing agent are fully contacted and mixed, thereby improving the sufficiency of ferrovanadium smelting, and further improving the quality of the finished product of ferrovanadium smelting solution in the smelting furnace;
[0055] Therefore, in the prior art, the aluminothermic method uses aluminum as a reducing agent, and adopts a bottom ignition method to smelt in a furnace drum with an alkaline furnace lining; first, the mixed furnace charge is loaded into the reactor and ignited; after the reaction starts, the remaining furnace charge is added in succession; however, during the smelting process, the lean slag and bottom solution contained in the ferrovanadium raw material are difficult to fully contact and mix with the reducing agent powder on the surface, resulting in insufficient ferrovanadium smelting, thereby reducing the quality of the finished ferrovanadium smelting solution in the smelting furnace;
[0056] The present invention promotes the full contact and mixing of the solution in the furnace body 1 and the reducing agent powder by the cooperation of the driving component 7 and the feeding component 8, thereby fully improving the smelting of ferrovanadium and further improving the quality of the finished ferrovanadium smelting solution in the smelting furnace; wherein, during the swinging of the furnace body 1, the fixing pins 5 on both sides of the furnace body 1 prevent the arc-shaped rack 6 from being misaligned with the driving component 7, causing the furnace body 1 to tip over, thereby reducing the risk of the furnace body 1 tipping over during operation.
[0057] As a specific embodiment of the present invention, the driving assembly 7 includes:
[0058] A load-bearing plate 71, both ends of which are embedded in the shell wall of the shell 2 and fixedly connected to the shell 2; a slide groove 72 is provided on the load-bearing plate 71;
[0059] The slide plate 73 is sleeved in the slide groove 72; the slide plate 73 is slidably connected to the slide groove 72; one end of the slide plate 73 is fixedly connected to the hydraulic cylinder 4;
[0060] Rack 74; the rack 74 is fixedly connected to the slide plate 73, and the rack 74 is meshed with the arc-shaped rack 6;
[0061] When the hydraulic cylinder 4 is started, the hydraulic cylinder 4 pushes the slide plate 73 on the load-bearing plate 71 to move forward along the slide groove 72. During the forward movement, the transmission of the rack 74 on the slide plate 73 and the arc-shaped rack 6 causes the furnace body 1 to tilt to the right. At this time, the solution in the furnace impacts the right furnace wall; when the hydraulic cylinder 4 contracts, it pulls the slide plate 73 on the load-bearing plate 71 to move backward along the slide groove 72. During the backward movement, the transmission of the rack 74 on the slide plate 73 and the arc-shaped rack 6 causes the furnace body 1 to tilt to the left. At this time, the solution in the furnace body 1 impacts the left furnace wall from the right furnace wall again, and the hydraulic cylinder 4 drives the driving assembly 7 to perform linear reciprocating motion. Each reciprocating motion causes the solution in the furnace to roll continuously due to the impact, which accelerates the melting of the charge, thereby increasing the rate of vanadium extraction from the charge.
[0062] As a specific embodiment of the present invention, the feeding assembly 8 comprises:
[0063] The reduction box 81 is fixedly connected to the housing 2;
[0064] A first feed inlet 82; the first feed inlet 82 is provided at the top of the reduction box 81;
[0065] Feed pipe 83; the feed pipe 83 is fixedly connected to the furnace body 1; and is connected to the furnace body 1;
[0066] A material guide pipe 84; one end of the material guide pipe 84 is fixedly connected to the reduction box 81 and is connected to the reduction box 81; one end of the material guide pipe 84 away from the reduction box 81 is fixedly connected to the feed pipe 83;
[0067] Airbag 85; the airbag 85 is disposed between the reduction boxes 81; both sides of the airbag 85 are fixedly connected to the reduction boxes 81;
[0068] Through hole 86; the reduction box 81 is provided with a through hole 86 on one side away from the housing 2; the through hole 86 is fixedly connected to the airbag 85;
[0069] When the driving assembly 7 makes a reciprocating linear motion, the slide plate 73 moves back and forth in the slide groove 72. In the process of the slide plate 73 moving forward, the slide plate 73 passes through the shell 2 along the slide groove 72 and reaches the feeding assembly 8, squeezing the air bag 85 in the middle of the reduction box 81, and squeezing the gas in the air bag 85 into the reduction box 81 on both sides of the air bag 85. Under continuous squeezing, the gas entering the reduction box 81 blows up the reduction powder, and the blown reduction powder flows into the furnace body 1 through the guide pipe 84 and the feed pipe 83; so that the reduction powder contacts with the solution in the furnace, and then the solution contacts and reacts with the reduction powder, and the slide plate During the process of pulling back 73, the slide plate 73 and the air bag 85 are gradually separated, and the air is sucked into the air bag 85 through the through hole 86. At the same time, the air bag 85 stops blowing air to the reduction box, thereby stopping the supply of reducing powder to the furnace; giving the solution in the furnace time to contact with the reducing powder; reciprocating linear motion, so that when the furnace body 1 swings, the range of reducing powder to the tank is expanded, thereby improving the full contact between the solution and the reducing powder, and further improving the quality of the finished vanadium iron smelting solution in the smelting furnace; and a No. 1 feed port 82 is provided on the top of the reduction box for replenishing the reducing agent powder, thereby achieving a repeatable replenishment effect.
[0070] As a specific embodiment of the present invention, a baffle 13 is provided at the bottom of the furnace body 1;
[0071] When the furnace body 1 swings, the solution in the furnace sways back and forth, and the baffle 13 at the bottom of the furnace body 1 collides with the solution, so that the solution inside the furnace body 1 forms a wave due to the collision. The wave blows up the lean slag and solution at the bottom of the furnace body 1, so that the solution in the furnace body 1 is fully mixed, and then fully reacts with the reducing powder on the surface, thereby improving the quality of the finished product of the ferrovanadium smelting solution in the smelting furnace.
[0072] As a specific embodiment of the present invention, a one-way exhaust valve 87 is provided at the fixed connection between the air bag 85 and the reduction box 81;
[0073] When the slide plate 73 squeezes the airbag 85, the gas in the airbag 85 is discharged into the reduction box 81 through the one-way exhaust valve 87, blowing up the reduction powder in the reduction box 81; when the slide plate 73 leaves, the one-way exhaust valve 87 closes automatically, preventing the powder in the reduction box 81 from being sucked into the airbag 85, thereby reducing the waste of reduction powder; through the cyclic force of the slide plate 73 on the airbag 85, an orderly and effective exhaust effect is achieved.
[0074] As a specific embodiment of the present invention, the material guide pipe 84 is a corrugated pipe;
[0075] The guide pipe 84 is a corrugated tube. When the furnace body 1 swings, it stretches and contracts along with the swing of the furnace body 1, thereby increasing the swing range of the furnace body 1. When the swing range of the furnace body 1 becomes larger, the lean slag and solution at the bottom of the furnace body 1 surge from the bottom to the upper part along with the swing of the furnace body 1, and then fully react with the reducing powder flowing from the corrugated tube into the furnace body 1, thereby further improving the quality of the finished vanadium-ferrometallurgical solution in the smelting furnace.
[0076] As a specific embodiment of the present invention, the airbag 85 is made of high temperature resistant material;
[0077] The airbag 85 is made of high temperature resistant material, such as silicone rubber, etc., with good thermal stability. It is not easy for the airbag 85 to expand due to high temperature during the working process, which reduces the danger of work. At the same time, it has high mechanical strength. When the slide plate 73 and the airbag 85 are matched, it has good practicality, thereby improving the use effect of the vanadium iron smelting furnace.
[0078] As a specific embodiment of the present invention, a one-way air inlet valve 88 is provided at the fixed connection between the airbag 85 and the through hole 86;
[0079] During the contact between the slide plate 73 and the airbag 85, when the slide plate 73 squeezes the airbag 85, the gas in the airbag 85 can only be blown out from the one-way exhaust valve 87 and cannot be discharged from the one-way intake valve 88, thereby reducing the waste of gas in the airbag 85 and increasing the amount of gas flowing into the one-way exhaust valve 87. When the slide plate 73 leaves the airbag 85, the airbag 85 gradually returns to its original position, further allowing air to be sucked into the airbag 85 through the one-way intake valve 88, causing it to inhale and expand and open, while the airbag 85 gradually returns to its original state, so that the next time the slide plate 73 contacts the airbag 85, there is sufficient gas to flow to the one-way exhaust valve 87 for repeated use.

[0081] When the reaction of the furnace body 1 is completed, the discharge port 9 is opened using a special furnace hook. Since the diameter of the discharge port 9 close to the furnace body 1 is larger than the diameter of the discharge port 9 away from the furnace body 1, when the ferrovanadium solution flows out of the discharge port 9, the pressure and flow rate will increase, thereby accelerating the fluidity of the ferrovanadium solution and reducing the heat loss of the ferrovanadium solution when it flows into the distillation stage, thereby improving the quality of the finished ferrovanadium solution.
[0082] As a specific embodiment of the present invention, a spring 12 is provided at the semicircular arc of the top of the furnace body 1 and the shell 2;
[0083] When the furnace body 1 swings, the furnace body 1 hits the spring 12, and the spring 12 is compressed, which buffers the impact force of the furnace body 1 while compressing, thereby avoiding the furnace body 1 from directly colliding with the shell 2, reducing the probability of damage to the shell 2 and the furnace body 1 due to collision, and thereby increasing the service life of the fermentation equipment.
[0084] The specific workflow is as follows:
[0085] The staff first puts the mixed furnace charge into the furnace body 1, and heats and melts the mixed furnace charge in the furnace body 1 through the electric heating element arranged in the furnace body 1; after the reaction starts, the remaining furnace charge is added successively; after the furnace charge is added, the feed port 11 is closed, and the hydraulic cylinder 4 is started at this time, and the hydraulic cylinder 4 drives the driving component 7 to move, and the driving component 7 cooperates with the meshing arc-shaped rack 6, thereby driving the furnace body 1 to swing; when the furnace body 1 swings, the furnace body 1 hits the spring 12, and the spring 12 is compressed, and the impact force of the furnace body 1 is buffered while being compressed, thereby avoiding the furnace body 1 from directly colliding with the shell 2, reducing the probability of damage to the shell 2 and the furnace body 1 due to the collision, thereby increasing the service life of the fermentation equipment;
[0086] By utilizing the inertia of swinging, the melted solution of the charge in the furnace body 1 is constantly shaken, thereby driving the unmelted charge to absorb heat, accelerating the melting of the charge, and increasing the melting rate of the charge; during the swinging process of the furnace body 1, the fixing pins 5 on both sides of the furnace body 1 prevent the arc-shaped rack 6 from being misaligned with the driving assembly 7, and at the same time reduce the pressure of the furnace body on the load-bearing plate 71, thereby increasing the swinging rate of the furnace body and further improving the effect of fully stirring the solution in the furnace body;
[0087] While the hydraulic cylinder 4 drives the driving assembly 7 to move, the driving assembly 7 squeezes the feeding assembly 8. When the slide plate 73 squeezes the airbag 85, the gas in the airbag 85 is discharged into the reduction box 81 through the one-way exhaust valve 87, and the reduction powder in the reduction box 81 is blown up; the blown reduction powder flows into the furnace body 1 through the guide pipe 84 and the feed pipe 83; so that the reduction powder contacts the solution in the furnace, and at the same time, the bellows stretches and contracts with the swing of the furnace body 1, thereby increasing the swing range of the furnace body 1. When the swing range of the furnace body 1 becomes larger, the lean slag and solution at the bottom of the furnace body 1 surge from the bottom to the upper part with the swing of the furnace body 1, and then fully mix with the reduction powder flowing from the bellows into the furnace body 1. reaction; when the slide plate 73 leaves, the airbag 85 gradually returns to its original position, and further allows air to be sucked into the airbag 85 through the one-way air inlet valve 88, causing it to inhale and expand and open, while the airbag 85 gradually returns to its original state, so that when the slide plate 73 and the airbag 85 are next moved, there is sufficient gas to pass to the one-way exhaust valve 87 for repeated use; through the cyclic force of the slide plate 73 on the airbag 85, an orderly and effective exhaust effect is achieved; the pressure of the driving component 7 on the feeding component 8 is used to transport the reducing agent in the feeding component 8 to the furnace body 1, so that the swinging solution is fully contacted and mixed with the reducing agent, thereby improving the sufficiency of ferrovanadium smelting, and then improving the quality of the finished ferrovanadium smelting solution in the smelting furnace.
