Description

Technical Field

[0001] The invention belongs to the technical field of aluminum material processing, and in particular relates to aluminum smelting full oxygen combustion equipment. Background Art

[0002] Aluminum smelting refers to melting aluminum ores, such as diaspore, boehmite and gibbsite, and causing them to undergo a reduction reaction with reducing agents such as carbon, carbon monoxide and hydrogen at the high temperature provided by the smelting furnace, thereby converting aluminum from a combined state into a free state, thereby obtaining aluminum alone. In the smelting field, the use of air with an oxygen content of ≥85% to participate in combustion is called full oxygen combustion. Currently, full oxygen burners are installed in the combustion furnace for metal smelting, which has lower pollution.

[0003] Currently, in the process of aluminum ore smelting, workers need to open the furnace cover and then pour the materials into the furnace. During this process, if there is no molten aluminum liquid in the furnace as a buffer, the materials falling from a high place will have a violent collision with the furnace body, which may easily cause damage to the furnace body. If there is molten aluminum liquid in the furnace as a buffer, the materials falling from a high place will hit the aluminum liquid, causing aluminum liquid to splash. The high-temperature aluminum liquid can easily cause burns to the workers, causing safety hazards.

[0004] In view of this, in order to improve the above technical problems, the present invention provides aluminum smelting full oxygen combustion equipment to improve the above technical problems. Summary of the invention

[0005] Technical problem to be solved by the present invention: Currently, in the process of aluminum ore smelting, workers need to open the furnace cover and then pour materials into the furnace. During this process, if there is no molten aluminum liquid in the furnace as a buffer, the materials falling from a high place will have a violent collision with the furnace body, which may easily cause damage to the furnace body. If there is molten aluminum liquid in the furnace as a buffer, the materials falling from a high place will hit the aluminum liquid, causing splashing of the aluminum liquid. The high-temperature aluminum liquid can easily cause scalds to the workers, causing safety hazards.

[0006] The aluminum smelting oxyfuel combustion equipment provided by the present invention comprises an oxyfuel burner, and the aluminum smelting oxyfuel combustion equipment further comprises: a sealing disk, a furnace body assembly, a feeding unit and a transmission assembly;

[0007] The oxyfuel burner passes through the center of the sealing disk and is fixedly connected to the sealing disk;

[0008] The furnace body assembly is installed below the sealing plate, and the output end of the oxy-fuel burner is located inside the furnace body assembly;

[0009] The feeding unit is installed on the furnace body assembly, and is used to reduce the impact of the aluminum material on the furnace body assembly during feeding, and can also reduce the heat loss in the furnace body assembly during feeding;

[0010] The transmission assembly is arranged outside the furnace body assembly.

[0011] Through the cooperation of the sealing plate, the furnace body assembly and the feeding unit, the aluminum material is buffered by the flow guide of the components in the feeding unit when it falls, which reduces the impact damage to the furnace body when the aluminum material falls. The buffer components in the feeding unit can reduce the splashing of the molten liquid in the furnace body assembly, thereby improving the safety of aluminum smelting. At the same time, the feeding unit can automatically adjust the opening angle according to the flow rate of the aluminum material when it falls, thereby slowing down the heat loss inside the furnace body.

[0012] Furthermore, compared to the existing furnace body being fixed, or the furnace body and the oxy-fuel burner rotating at the same time, that is, when the furnace body and the oxy-fuel burner are relatively stationary, the oxy-fuel burner heats the aluminum material in the furnace at a single point, while the present invention drives the outer furnace body to rotate through a transmission component, thereby improving the fluidity of the internal molten liquid, and improving the contact effect between the aluminum material and the flame of the oxy-fuel burner, so that the aluminum material in the furnace is heated more evenly, and the flame of the oxy-fuel burner can achieve multi-point heating of the aluminum material in the furnace body, thereby improving the smelting effect.

[0013] Preferably, the furnace body assembly comprises: an inner furnace body, an outer furnace body, a connecting ring, a first bracket and a second bracket;

[0014] The inner furnace body is arranged below the sealing plate;

[0015] The outer furnace body is sleeved on the outside of the inner furnace body and is fixedly connected to the inner furnace body;

[0016] The connecting ring is arranged above the outer furnace body, and the connecting ring is slidably connected with the inner furnace body;

[0017] The No. 1 bracket is fixedly connected to the connecting ring;

[0018] The second bracket is slidably connected to the outer furnace body.

[0019] Preferably, the feed unit comprises: a feed box, a sealing door, a No. 1 spring, an arc plate and a No. 2 spring;

[0020] The feed box is arranged above the inner furnace body, the feed box is fixed to the connecting ring, and the feed box is fixed by a fixing frame;

[0021] The sealing doors are provided with two and contact each other, and the two sealing doors are both installed on the upper surface of the feed box and are rotatably connected to the feed box;

[0022] The first spring is arranged between the sealing door and the feed box, and its two ends are respectively fixedly connected to the sealing door and the feed box;

[0023] There are two arc-shaped plates, one end of each of which is rotatably connected to the connecting ring, the lower ends of the two arc-shaped plates are located in the inner furnace body, and the two arc-shaped plates are arranged in a "V" shape in the initial state;

[0024] The No. 2 spring is arranged between the arc plate and the inner furnace body, one end of the No. 2 spring is fixedly connected to the arc plate, and the other end of the No. 2 spring is fixedly connected to the inner furnace body.

[0025] Preferably, the transmission assembly comprises: a ring gear, a gear and a motor;

[0026] The gear ring is fixedly connected to the outer surface of the outer furnace body;

[0027] The gear is arranged on one side of the gear ring, and the gear ring is meshed with the gear;

[0028] The motor output shaft passes through the center of the gear and is fixedly connected to the gear.

[0029] When aluminum smelting is required, the staff first controls the sealing plate to rotate through the controller, and the sealing plate drives the oxy-fuel burner to rotate. At this time, the sealing plate gradually moves away from the inner furnace body, and the furnace body assembly is in an open state. At this time, the heat in the furnace diffuses outward to the feed box. Then, when the aluminum is located on the feed box, the two sealing doors are automatically opened by the gravity of the aluminum. At this time, the aluminum falls into the furnace body due to its own weight;

[0030] When the aluminum material falls into the inner furnace body through the feed box, it gradually pushes the two V-shaped arc plates to both sides, and the arc plates move to both sides to squeeze the second spring. Therefore, the aluminum material that first falls into the inner furnace body is blocked and buffered by the arc plates, and slowly falls into the inner furnace body along the arc plates, reducing the impact force of the aluminum material falling directly into the inner furnace body, thereby reducing the impact of the aluminum material on the furnace body when it falls;

[0031] At the same time, if there is still molten liquid in the inner furnace body when the aluminum material falls, the arc plates on both sides can reduce the splash height of part of the molten liquid and block part of the splashing molten liquid, thereby improving the safety of aluminum smelting;

[0032] When the aluminum material on the sealing door enters the furnace body, the sealing door is no longer subject to the gravity of the aluminum material, and the No. 1 spring recovers its elastic deformation to drive the sealing door to close automatically and quickly. Then the staff controls the sealing disk to rotate in the opposite direction through the controller to seal the inner furnace body, shortening the time when the inner furnace body is fully open and reducing the heat loss in the furnace body. Then the controller controls the full oxygen burner to work and burn and smelt the aluminum material in the furnace body assembly.

[0033] When the oxy-fuel burner heats and smelts the aluminum in the furnace assembly, the staff controls the motor to start through the controller, the motor output shaft rotates to drive the gear to rotate, the gear drives the outer furnace body to rotate through gear meshing, and the outer furnace body rotates to drive the inner furnace body to rotate. When the inner furnace body rotates, the fluidity of the internal molten liquid can be improved, and the contact effect between the aluminum and the flame of the oxy-fuel burner can be improved, so that the flame of the oxy-fuel burner can heat the aluminum in the furnace at multiple points, so that the aluminum in the furnace is heated more evenly, and the smelting effect is improved;

[0034] At the same time, since the connecting ring is slidably connected to the inner furnace body and is fixed by the feed box and the fixing frame, the connecting ring will not rotate with the inner furnace body. At this time, as the falling aluminum materials gradually increase, the arc plate contacts the inner wall of the inner furnace body, and the inner furnace body rotates, so the inner furnace body and the arc plate move relative to each other, and the arc plate can clean and scrape the residue on the inner wall of the inner furnace body, which is convenient for the smelting of the next group of aluminum materials.

[0035] When the aluminum material gradually turns into molten liquid, the arc plate is no longer squeezed by the aluminum material, and the second spring recovers its elastic deformation to drive the arc plate to move toward the middle of the inner furnace body. At this time, due to the continuous rotation of the inner furnace body, the arc plate and the inner furnace body move relative to each other, so the arc plate can stir the molten liquid and part of the unmelted aluminum material in the inner furnace body, improve the fluidity of the solution in the inner furnace body, and improve the uniform heating of the aluminum material;

[0036] Preferably, a guide unit is provided on the side wall of the furnace body assembly, and the guide unit is used to guide the hot air flow around the furnace wall and filter the hot air flow, and the guide unit includes: an air outlet, a filter ring and an exhaust hole;

[0037] The gas outlet is provided on the inner furnace body;

[0038] There are multiple filter rings, each of which is located in the gap between the inner furnace body and the outer furnace body, the inner wall of the filter ring is fixedly connected to the inner furnace body, and the outer part of the filter ring is fixedly connected to the outer furnace body;

[0039] The exhaust hole is opened on the outer furnace body, and the exhaust hole is located below the air outlet hole.

[0040] The heat-carrying gas generated when aluminum is smelted in the furnace body is discharged from the outlet into the gap between the inner furnace body and the outer furnace body. During smelting, the high-temperature gas generated between the side walls of the inner furnace body and the outer furnace body can have an insulation effect on the furnace body, slow down the cooling rate of the furnace body, save energy, and further improve the smelting effect.

[0041] Preferably, the bottoms of the inner furnace body and the outer furnace body are both configured as hemispherical structures, a discharge pipe is fixedly connected to the bottom of the inner furnace body, the discharge pipe is fixedly connected to the inner furnace body, and the discharge pipe passes through the outer furnace body and is fixedly connected to the outer furnace body.

[0042] By setting the bottom of the inner furnace body and the outer furnace body to be a hemispherical structure, the molten aluminum can be discharged from the discharge pipe along the spherical arc due to its own weight, thereby preventing part of the molten aluminum from being unable to be fully discharged from the inner furnace body.

[0043] At the same time, a filter is installed at the discharge pipe to filter the molten aluminum to prevent the molten aluminum containing more impurities from entering the subsequent process.

[0044] Preferably, a plurality of steel balls are provided in the filter ring, and the steel balls can move freely in the filter ring.

[0045] When the outer furnace body and the inner furnace body rotate, the filter ring can be driven to rotate. The rotation of the filter ring can drive the steel balls inside it to roll in the filter ring. When the steel balls roll, they can disturb the gas flow through the filter ring, extend the gas flow path, and improve the filtering effect of the filter ring.

[0046] Preferably, the two sealed doors include door No. 1 and door No. 2, a side of door No. 1 close to door No. 2 is fixedly connected with an inverted L-shaped block, a side of door No. 2 close to door No. 1 is fixedly connected with a straight L-shaped block, and the inverted L-shaped block and the straight L-shaped block fit together.

[0047] By fixing the positive L-shaped block and the inverted L-shaped block on the contact surfaces of the two sealing doors, when the sealing doors are closed, the contact area and the fitting effect of the two sealing doors can be increased, thereby ensuring the sealing effect of the sealing doors.

[0048] Preferably, a hinged rod is fixedly connected to the lower surface of the second door, and one end of the hinged rod away from the second door is fixedly connected to the feed box.

[0049] When Door No. 2 is opened, supported by the hinge rod, Door No. 2 is inclined, and when Door No. 1 is opened, it is also inclined due to the limiting effect of the sealing plate, but the lower end height of Door No. 1 when tilted is higher than the lower end height of Door No. 2 when tilted. Therefore, Door No. 2 and Door No. 1 act as guide plates, and the aluminum material first slides down along Door No. 1, and part of the aluminum material directly enters the furnace body, while the other part falls on Door No. 2, and then slides down along Door No. 2 into the inner furnace body, to prevent all the aluminum material from entering the inner furnace body when falling.

[0050] Preferably, a plurality of through holes are formed on the arc-shaped plate.

[0051] By opening a plurality of through holes on the arc plate, the impact of the arc plate on the contact between the flame and the aluminum material can be reduced, and the blocking of the flame by the arc plate can be reduced.

[0052] The beneficial effects of the present invention are as follows:

[0053] 1. The aluminum smelting oxyfuel combustion equipment provided by the present invention cooperates with each other through the sealing plate, the furnace body assembly and the feeding unit. When the aluminum material falls, it is buffered by the flow guide of the components in the feeding unit, thereby reducing the impact damage to the furnace body when the aluminum material falls. The buffer components in the feeding unit can reduce the splashing phenomenon of the molten liquid in the furnace body assembly, thereby improving the safety of aluminum smelting. At the same time, the feeding unit can automatically adjust the opening angle according to the flow rate of the aluminum material when it falls, thereby slowing down the heat loss inside the furnace body.

[0054] 2. The aluminum smelting oxy-fuel combustion equipment provided by the present invention drives the outer furnace body to rotate through the transmission component, which can improve the fluidity of the internal molten liquid and the contact effect between the aluminum material and the flame of the oxy-fuel burner, so that the aluminum material in the furnace is heated more evenly, and the flame of the oxy-fuel burner can achieve multi-point heating of the aluminum material in the furnace body, thereby improving the smelting effect.

[0055] 3. The aluminum smelting oxyfuel combustion equipment provided by the present invention has an arc plate, and when the aluminum material falls into the inner furnace body through the feed box, the two arc plates arranged in a V shape are gradually pushed to both sides, and the arc plates move to both sides to squeeze the second spring. Therefore, the aluminum material that falls into the inner furnace body first is blocked and buffered by the arc plate, which reduces the impact of the aluminum material on the furnace body when it falls;

[0056] At the same time, if there is still molten liquid in the inner furnace body when the aluminum material falls, the arc plates on both sides can reduce the splash height of part of the molten liquid and block part of the splashing molten liquid, thereby improving the safety of aluminum smelting;

[0057] At the same time, as the falling aluminum materials gradually increase, the arc plate contacts the inner wall of the inner furnace body, and the inner furnace body rotates, so the inner furnace body and the arc plate move relative to each other, and the arc plate can clean and scrape the residue on the inner wall of the inner furnace body, which is convenient for the smelting of the next group of aluminum materials;

[0058] When part of the aluminum material is gradually converted into molten liquid, the arc plate moves toward the middle of the inner furnace body. At this time, due to the continuous rotation of the inner furnace body, the arc plate and the inner furnace body move relative to each other. Therefore, the arc plate can stir the molten liquid and part of the unmelted aluminum material in the inner furnace body, thereby improving the fluidity of the solution in the inner furnace body and improving the uniform heating of the aluminum material.

[0059] 4. The aluminum smelting full oxygen combustion equipment provided by the present invention is provided with a guide unit so that during smelting, the high-temperature gas generated is located between the inner furnace body and the side wall of the outer furnace body, which can have an insulation effect on the furnace body, slow down the cooling rate of the furnace body, save energy, and further improve the smelting effect, thereby improving the cleanliness of the later gas when it is discharged from the exhaust pipe at the exhaust hole.

DETAILED DESCRIPTION

[0068] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0069] like Figure 1 and Figure 2 As shown, the aluminum smelting oxyfuel combustion equipment provided by the present invention includes an oxyfuel burner 1, and the aluminum smelting oxyfuel combustion equipment also includes: a sealing plate 2, a furnace body assembly 3, a feeding unit 4 and a transmission assembly 5;

[0070] The oxyfuel burner 1 passes through the center of the sealing disk 2 and is fixedly connected to the sealing disk 2;

[0071] The furnace body assembly 3 is installed below the sealing plate 2, and the output end of the oxyfuel burner 1 is located inside the furnace body assembly 3;

[0072] The feeding unit 4 is installed on the furnace body assembly 3. The feeding unit 4 is used to reduce the impact of the aluminum material on the furnace body assembly 3 during feeding and also reduce the heat loss in the furnace body assembly 3 during feeding.

[0073] The transmission assembly 5 is arranged outside the furnace body assembly 3 and is used to drive the furnace body assembly 3 to rotate;

[0074] By adopting the above technical solution, when aluminum smelting is required, the staff first controls the sealing plate to rotate through the controller, and the sealing plate drives the oxy-fuel burner 1 to rotate. At this time, the sealing plate gradually moves away from the furnace body assembly 3, and the furnace body assembly 3 is in an open state. At this time, the heat in the furnace diffuses outward to the feeding unit 4;

[0075] Then, when the aluminum material is located on the feeding unit 4, the feeding unit 4 automatically opens due to the gravity of the aluminum material, and the aluminum material falls into the furnace body due to its own weight. When the aluminum material falls into the furnace body assembly 3 through the feeding unit 4, it is buffered by the flow diversion of the components in the feeding unit 4, thereby reducing the impact damage to the furnace body when the aluminum material falls. The buffer components in the feeding unit 4 can reduce the splashing of the molten liquid in the furnace body assembly 3, thereby improving the safety of aluminum smelting. When the aluminum material on the feeding unit 4 enters the furnace body, the feeding unit 4 automatically closes without being affected by the gravity of the aluminum material. Then, the staff controls the sealing disk 2 to rotate in the opposite direction through the controller to seal the furnace body assembly 3. Therefore, the feeding unit 4 can automatically adjust the opening angle according to the flow rate when the aluminum material falls, thereby shortening the time when the furnace body is fully open and reducing the heat loss in the furnace body. Then, the controller controls the operation of the oxyfuel burner 1 to burn and smelt the aluminum material in the furnace body assembly 3.

[0076] When the oxy-fuel burner 1 heats and smelts the aluminum material in the furnace body assembly 3, the staff controls the transmission assembly 5 to work through the controller, and the transmission assembly 5 drives the furnace body assembly 3 to rotate. When the furnace body assembly 3 rotates, the fluidity of the internal molten liquid can be improved, and the contact effect between the aluminum material and the flame of the oxy-fuel burner 1 can be improved, so that the flame of the oxy-fuel burner 1 can heat the aluminum material in the furnace body at multiple points, so that the aluminum material in the furnace is heated more evenly, and the smelting effect is improved;

[0077] Compared with the prior art, when aluminum is smelted, the aluminum is directly added into the furnace body. Due to the gravity of the aluminum, the furnace body will be impacted and damaged. If the aluminum is added again when there is still molten liquid in the furnace body, the impact force of the aluminum when it falls will cause the high-temperature molten liquid in the furnace body to produce impact force, causing the molten liquid to splash, which poses a safety hazard. In the present invention, the sealing plate 2, the furnace body assembly 3 and the feeding unit 4 cooperate with each other. When the aluminum falls, it is buffered by the flow diversion of the elements in the feeding unit 4, which reduces the impact damage to the furnace body when the aluminum falls. The buffer element in the feeding unit 4 can reduce the splashing of the molten liquid in the furnace body assembly 3, thereby improving the safety of aluminum smelting. At the same time, the feeding unit 4 can automatically adjust the opening angle according to the flow rate of the aluminum when it falls, thereby slowing down the heat loss inside the furnace body.

[0078] Furthermore, compared to the existing furnace body being fixed, or the furnace body and the oxy-fuel burner 1 rotating simultaneously, that is, when the furnace body and the oxy-fuel burner 1 are relatively stationary, the oxy-fuel burner 1 heats the aluminum material in the furnace at a single point, while the present invention drives the outer furnace body to rotate by the transmission component 5, thereby improving the fluidity of the internal molten liquid, and improving the contact effect between the aluminum material and the flame of the oxy-fuel burner 1, so that the aluminum material in the furnace is heated more evenly, and the flame of the oxy-fuel burner 1 can achieve multi-point heating of the aluminum material in the furnace body, thereby improving the smelting effect.

[0079] like Figures 1 to 6 As shown, as a specific embodiment of the present invention, the furnace body assembly 3 includes: an inner furnace body 31, an outer furnace body 32, a connecting ring 33, a first bracket 34 and a second bracket 35;

[0080] The inner furnace body 31 is arranged below the sealing plate 2;

[0081] The outer furnace body 32 is sleeved on the outside of the inner furnace body 31 and is fixedly connected to the inner furnace body 31;

[0082] The connecting ring 33 is disposed above the outer furnace body 32, and the connecting ring 33 is slidably connected to the inner furnace body 31;

[0083] The first bracket 34 is fixedly connected to the connecting ring 33;

[0084] The second bracket 35 is slidably connected to the outer furnace body 32;

[0085] The feeding unit 4 comprises: a feeding box 41, a sealing door 42, a No. 1 spring 43, an arc plate 44 and a No. 2 spring 45;

[0086] The feed box 41 is disposed above the inner furnace body 31 , and the feed box 41 is fixed to the connecting ring 33 , and the feed box 41 is fixed by a fixing frame;

[0087] The sealing doors 42 are provided with two and contact each other, and the two sealing doors 42 are both installed on the upper surface of the feed box 41 and are rotatably connected to the feed box 41;

[0088] The first spring is arranged between the sealing door 42 and the feed box 41, and its two ends are respectively fixedly connected to the sealing door 42 and the feed box 41;

[0089] There are two arc plates 44, one end of each of the two arc plates 44 is rotatably connected to the connecting ring 33, the lower ends of the two arc plates are located in the inner furnace body 31, and the two arc plates 44 are arranged in a "V" shape in the initial state;

[0090] The second spring 45 is disposed between the arc plate 44 and the inner furnace body 31 , and one end of the second spring 45 is fixedly connected to the arc plate 44 , and the other end is fixedly connected to the inner furnace body 31 ;

[0091] The transmission assembly 5 includes: a ring gear 51, a gear 52 and a motor 53;

[0092] The gear ring 51 is fixedly connected to the outer surface of the outer furnace body 32;

[0093] The gear 52 is disposed on one side of the gear ring 51, and the gear ring 51 is meshed with the gear 52;

[0094] The output shaft of the motor 53 passes through the center of the gear 52 and is fixedly connected to the gear 52;

[0095] By adopting the above technical solution, when aluminum smelting is required, the staff first controls the sealing plate to rotate through the controller, and the sealing plate drives the oxy-fuel burner 1 to rotate. At this time, the sealing plate gradually moves away from the inner furnace body 31, and the furnace body assembly 3 is in an open state. At this time, the heat in the furnace diffuses outward to the feed box 41, and then when the aluminum is located on the feed box 41, the two sealing doors 42 are automatically opened by the gravity of the aluminum, and the aluminum falls into the furnace body due to its own weight;

[0096] When the aluminum material falls into the inner furnace body 31 through the feed box 41, the two V-shaped arc plates 44 are gradually pushed open to both sides, and the arc plates 44 move to both sides to squeeze the second spring 45. Therefore, the aluminum material that first falls into the inner furnace body 31 is blocked and buffered by the arc plates 44, and slowly falls into the inner furnace body 31 along the arc plates 44, reducing the impact force of the aluminum material falling directly into the inner furnace body 31, thereby reducing the impact of the aluminum material on the furnace body when falling;

[0097] At the same time, if there is still molten liquid in the inner furnace body 31 when the aluminum material falls, the arc-shaped plates 44 on both sides can reduce the splash height of part of the molten liquid and can block part of the splashed molten liquid, thereby improving the safety of aluminum material smelting;

[0098] When the aluminum material on the sealing door 42 enters the furnace body, the sealing door 42 is no longer subject to the gravity of the aluminum material, and the No. 1 spring 43 recovers its elastic deformation to drive the sealing door 42 to close automatically and quickly. Then the staff controls the sealing disk 2 to rotate in the opposite direction through the controller to seal the inner furnace body 31, shortening the time when the inner furnace body 31 is fully open, reducing the heat loss in the furnace body, and then controls the full oxygen burner 1 to work through the controller to burn and smelt the aluminum material in the furnace body assembly 3;

[0099] When the oxy-fuel burner 1 heats and smelts the aluminum material in the furnace body assembly 3, the staff controls the motor 53 to start through the controller, the output shaft of the motor 53 rotates to drive the gear 52 to rotate, the gear 52 drives the outer furnace body 32 to rotate through the meshing of the gear 52, and the rotation of the outer furnace body 32 drives the inner furnace body 31 to rotate. When the inner furnace body 31 rotates, the fluidity of the internal molten liquid can be improved, and the contact effect between the aluminum material and the flame of the oxy-fuel burner 1 can be improved, so that the flame of the oxy-fuel burner 1 can achieve multi-point heating of the aluminum material in the furnace body, so that the aluminum material in the furnace is heated more evenly, and the smelting effect is improved;

[0100] At the same time, since the connecting ring 33 is slidably connected to the inner furnace body 31 and the connecting ring 33 is fixed by the feed box 41 and the fixing frame, the connecting ring 33 will not rotate with the inner furnace body 31. At this time, as the falling aluminum material gradually increases, the arc plate 44 contacts the inner wall of the inner furnace body 31, and the inner furnace body 31 rotates, so the inner furnace body 31 and the arc plate 44 move relative to each other, and the arc plate 44 can clean and scrape the residue on the inner wall of the inner furnace body 31, so as to facilitate the smelting of the next group of aluminum materials.

[0101] When part of the aluminum material is gradually converted into molten liquid, the arc plate 44 is no longer squeezed by the aluminum material, and the No. 2 spring 45 restores its elastic deformation to drive the arc plate 44 to move toward the middle of the inner furnace body 31. At this time, due to the continuous rotation of the inner furnace body 31, the arc plate 44 and the inner furnace body 31 move relative to each other, so the arc plate 44 can stir the molten liquid and part of the unmelted aluminum material in the inner furnace body 31, thereby improving the fluidity of the solution in the inner furnace body 31 and improving the uniform heating of the aluminum material.

[0102] like Figure 1 and Figure 6 As shown, as a specific embodiment of the present invention, the side wall of the furnace body assembly 3 is provided with a guide unit 6, the guide unit 6 is used to guide the hot air flow around the furnace wall and filter the hot air flow, and the guide unit 6 includes: an air outlet 61, a filter ring 62 and an exhaust hole 63;

[0103] The gas outlet 61 is provided on the inner furnace body 31;

[0104] There are multiple filter rings 62, and the filter rings 62 are located in the gap between the inner furnace body 31 and the outer furnace body 32. The inner wall of the filter ring 62 is fixedly connected to the inner furnace body 31, and the outer part of the filter ring 62 is fixedly connected to the outer furnace body 32.

[0105] The exhaust hole 63 is opened on the outer furnace body 32, and the exhaust hole 63 is located below the air outlet hole 61;

[0106] By adopting the above technical scheme, the heat-carrying gas generated when the aluminum material is smelted in the furnace body is discharged from the outlet hole 61 into the gap between the inner furnace body 31 and the outer furnace body 32. During smelting, the high-temperature gas generated between the side walls of the inner furnace body 31 and the outer furnace body 32 can have an insulation effect on the furnace body, slow down the cooling rate of the furnace body, save energy, and further improve the smelting effect, thereby improving the cleanliness of the gas when it is discharged from the exhaust pipe at the exhaust hole 63 in the later stage.

[0107] like Figure 1 and Figure 2 As shown, as a specific embodiment of the present invention, the bottoms of the inner furnace body 31 and the outer furnace body 32 are both configured as hemispherical structures, and a discharge pipe 7 is fixedly connected to the bottom of the inner furnace body 31, and the discharge pipe 7 is fixedly connected to the inner furnace body 31, and the discharge pipe 7 passes through the outer furnace body 32 and is fixedly connected to the outer furnace body 32;

[0108] By adopting the above technical solution, by setting the bottom of the inner furnace body 31 and the outer furnace body 32 to a hemispherical structure, it is possible to facilitate the aluminum melt to be discharged from the discharge pipe 7 along the spherical arc due to its own weight, thereby preventing part of the molten liquid from being unable to be fully discharged from the inner furnace body 31;

[0109] At the same time, a filter screen is provided at the discharge pipe 7 to filter the molten aluminum to prevent the molten aluminum containing more impurities from entering the subsequent process.

[0110] like Figure 6 As shown, as a specific embodiment of the present invention, a plurality of steel balls 8 are provided in the filter ring 62, and the steel balls 8 can move freely in the filter ring 62;

[0111] By adopting the above technical solution, when the outer furnace body 32 and the inner furnace body 31 rotate, the filter ring 62 can be driven to rotate. The rotation of the filter ring 62 can drive the steel ball 8 inside it to roll in the filter ring 62. When the steel ball 8 rolls, it can disturb the gas flow direction passing through the filter ring 62, extend the gas flow path, and improve the filtering effect of the filter ring 62.

[0112] like Figure 1 As shown, as a specific embodiment of the present invention, the two sealing doors 42 include a first door 421 and a second door 422, a side of the first door 421 close to the second door 422 is fixedly connected to an inverted L-shaped block 423, and a side of the second door 422 close to the first door 421 is fixedly connected to a positive L-shaped block 424, and the inverted L-shaped block 423 and the positive L-shaped block 424 fit together;

[0113] By adopting the above technical solution, by fixing the positive L-shaped block 424 and the inverted L-shaped block 423 on the contact surfaces of the two sealing doors 42, when the sealing doors 42 are closed, the contact area and the fitting effect of the two sealing doors 42 can be increased, thereby ensuring the sealing effect of the sealing doors 42.

[0114] like Figure 1 As shown, as a specific embodiment of the present invention, a hinge rod 9 is fixedly connected to the lower surface of the second door 422, and one end of the hinge rod 9 away from the second door 422 is fixedly connected to the feed box 41;

[0115] By adopting the above technical scheme, when door No. 2 422 is opened, supported by the hinge rod 9, door No. 2 422 is inclined, and when door No. 1 421 is opened, it is also inclined due to the limiting effect of the sealing plate 2, but the lower end height of door No. 1 421 when inclined is higher than the lower end height of door No. 2 422 when inclined. Therefore, door No. 2 422 and door No. 1 421 act as guide plates, and the aluminum material first slides down along door No. 1 421, part of the aluminum material directly enters the furnace body, and the other part of the aluminum material falls on door No. 2 422, and then slides down along door No. 2 422 into the inner furnace body 31, so as to avoid that the aluminum material cannot enter the inner furnace body 31 when falling.

[0116] like Figure 1 As shown, as a specific embodiment of the present invention, the arc plate 44 is provided with a plurality of through holes;

[0117] By adopting the above solution and opening a plurality of through holes on the arc plate 44 , the contact between the flame and the aluminum material caused by the existence of the arc plate 44 can be reduced, and the obstruction of the flame by the arc plate 44 can be reduced.

[0118] Working principle: When aluminum smelting is required, the staff first controls the sealing plate to rotate through the controller, and the sealing plate drives the oxy-fuel burner 1 to rotate. At this time, the sealing plate gradually moves away from the inner furnace body 31, and the furnace body assembly 3 is in an open state. At this time, the heat in the furnace diffuses outward to the feed box 41, and then when the aluminum is located on the feed box 41, the two sealing doors 42 are automatically opened by the gravity of the aluminum, and the aluminum falls into the furnace body due to its own weight;

[0119] When the aluminum material falls into the inner furnace body 31 through the feed box 41, the two V-shaped arc plates 44 are gradually pushed open to both sides, and the arc plates 44 move to both sides to squeeze the second spring 45. Therefore, the aluminum material that first falls into the inner furnace body 31 is blocked and buffered by the arc plates 44, and slowly falls into the inner furnace body 31 along the arc plates 44, reducing the impact force of the aluminum material falling directly into the inner furnace body 31, thereby reducing the impact of the aluminum material on the furnace body when falling;

[0120] At the same time, if there is still molten liquid in the inner furnace body 31 when the aluminum material falls, the arc-shaped plates 44 on both sides can reduce the splash height of part of the molten liquid and can block part of the splashed molten liquid, thereby improving the safety of aluminum material smelting;

[0121] When the aluminum material on the sealing door 42 enters the furnace body, the sealing door 42 is no longer subject to the gravity of the aluminum material, and the No. 1 spring 43 recovers its elastic deformation to drive the sealing door 42 to close automatically and quickly. Then the staff controls the sealing disk 2 to rotate in the opposite direction through the controller to seal the inner furnace body 31, shortening the time when the inner furnace body 31 is fully open, reducing the heat loss in the furnace body, and then controls the full oxygen burner 1 to work through the controller to burn and smelt the aluminum material in the furnace body assembly 3;

[0122] When the oxy-fuel burner 1 heats and smelts the aluminum material in the furnace body assembly 3, the staff controls the motor 53 to start through the controller, the output shaft of the motor 53 rotates to drive the gear 52 to rotate, the gear 52 drives the outer furnace body 32 to rotate through the meshing of the gear 52, and the rotation of the outer furnace body 32 drives the inner furnace body 31 to rotate. When the inner furnace body 31 rotates, the fluidity of the internal molten liquid can be improved, and the contact effect between the aluminum material and the flame of the oxy-fuel burner 1 can be improved, so that the flame of the oxy-fuel burner 1 can achieve multi-point heating of the aluminum material in the furnace body, so that the aluminum material in the furnace is heated more evenly, and the smelting effect is improved;

[0123] At the same time, since the connecting ring 33 is slidably connected to the inner furnace body 31 and the connecting ring 33 is fixed by the feed box 41 and the fixing frame, the connecting ring 33 will not rotate with the inner furnace body 31. At this time, as the falling aluminum material gradually increases, the arc plate 44 contacts the inner wall of the inner furnace body 31, and the inner furnace body 31 rotates, so the inner furnace body 31 and the arc plate 44 move relative to each other, and the arc plate 44 can clean and scrape the residue on the inner wall of the inner furnace body 31, so as to facilitate the smelting of the next group of aluminum materials.

[0124] When part of the aluminum material is gradually converted into molten liquid, the arc plate 44 is no longer squeezed by the aluminum material, and the second spring 45 recovers its elastic deformation to drive the arc plate 44 to move toward the middle of the inner furnace body 31. At this time, since the inner furnace body 31 continues to rotate, the arc plate 44 moves relative to the inner furnace body 31, so the arc plate 44 can stir the molten liquid and part of the unmelted aluminum material in the inner furnace body 31, thereby improving the fluidity of the solution in the inner furnace body 31 and improving the uniform heating of the aluminum material.

[0125] Then, the aluminum melt is discharged from the discharge pipe 7 to prevent part of the melt from being completely discharged from the inner furnace body 31;

[0126] At the same time, a filter screen is provided at the discharge pipe 7 to filter the molten aluminum to prevent the molten aluminum containing more impurities from entering the subsequent process.

[0127] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
