Description

Technical Field

[0001] The present invention belongs to the technical field of smelting equipment, and specifically relates to an aluminum profile smelting furnace. Background Art

[0002] An alloy with aluminum as the base and a certain amount of other alloying elements added is one of the light metal materials. Aluminum alloys have relatively high strength, and the specific strength is close to that of high alloy steel, and the specific stiffness exceeds that of steel. They have good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials, and are widely used in aerospace, aviation, transportation, construction, electromechanics, light chemical industry and daily necessities. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts has increased day by day. When producing aluminum, a smelting furnace is needed to smelt aluminum ore. When the traditional aluminum profile smelting furnace works, all the materials need to be added into the furnace body. After the outer layer of materials melts, the inner layer of materials melts, resulting in low production efficiency.

[0003] In the prior art, a patent on a technical solution for an aluminum profile smelting furnace has emerged. For example, a Chinese patent with the application number CN2019102209067 discloses an aluminum profile smelting furnace, including a melting furnace and a combustion chamber. One side of the melting furnace is fixedly connected with a feeding channel, the top of the feeding channel is connected with a storage channel, a thrust spring is fixedly connected to the inner wall of the feeding channel, one end of the thrust spring is connected with a moving plate, the top of the right side of the moving plate is fixedly connected with a top plate, and a T-shaped channel is opened on the right side surface of the moving plate; this invention realizes the functions of automatic feeding, intermittent feeding and preheating of raw materials by setting a storage channel, a feeding channel, a jet channel, a communicating pipe and a moving plate. By introducing the hot gas in the combustion chamber into the feeding channel to push the materials into the melting furnace, and during the process of pushing the materials, the hot gas preheats the materials. At the same time, every time the moving plate is pushed, the materials in the storage channel fall once, which is beneficial to improving the melting efficiency and the safety of workers; however, the above patent still has defects. In this invention, the combustion chamber is arranged below the smelting furnace, and the combustion chamber only contacts the bottom end of the smelting furnace, so the materials cannot be evenly heated well, reducing the working efficiency of the smelting furnace and limiting this technical solution.

[0004] In view of this, the present invention proposes an aluminum profile smelting furnace to solve the above technical problems. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve the problem that in the existing aluminum profile smelting furnace, due to uneven heating, the inner layer of materials melts only after the outer layer of materials melts during smelting, resulting in low production efficiency, the present invention provides an aluminum profile smelting furnace.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: an aluminum profile smelting furnace, comprising a furnace body, a furnace cover, a first heating chamber and a second heating chamber; the side wall of the furnace body is inclined, and feeding ports are evenly distributed at a position near the top end of the side wall of the furnace body; the furnace cover is arranged at the top end of the furnace body; a connecting block is fixedly installed at the middle position of the lower surface of the furnace cover, and the lower surface of the connecting block is parallel to the bottom end of the feeding port; the first heating chamber is arranged at the positions of the outer surfaces of the side wall and the bottom end of the furnace body, and the first heating chamber is in contact with the furnace body in a shape-matching manner; the position of the feeding port is higher than the upper surface of the top end of the first heating chamber; the second heating chamber is fixedly installed on the lower surface of the connecting block, and the lower surface of the bottom end of the second heating chamber is close to the middle position inside the furnace body.

[0007] During operation, materials are conveyed into the interior of the furnace body through the feeding ports on the side wall of the furnace body. Due to the inclination of the side wall of the furnace body, the materials roll down along the side wall of the furnace body from the feeding ports and keep rolling under the influence of gravity until they reach a position near the center of the upper surface of the bottom end of the furnace body; when adding materials continuously, the space between the upper surface of the bottom end of the furnace body and the lower surface of the bottom end of the second heating chamber is gradually filled with materials, and then the materials will accumulate in the space between the inner surface of the side wall of the furnace body and the outer surface of the side wall of the second heating chamber; when the materials accumulate near the bottom end of the feeding port, the feeding stops. Since the first heating chamber wraps the outer surfaces of the side wall and the bottom end of the furnace body from the outside, that is, it transfers heat to the materials from the outside to the inside, and the second heating chamber is wrapped by the materials inside the furnace body, that is, it transfers heat to the materials from the inside to the outside, the materials inside the furnace body are heated evenly and comprehensively, accelerating the melting speed of the materials and improving the production efficiency; at the same time, the second heating chamber inside the furnace body occupies the materials accumulated at this position in the traditional smelting furnace, solving the problem that the part of the materials near the side wall of the furnace body has been heated and melted first, but the middle part is not heated in time due to the too large accumulation thickness and always becomes in a molten state later, further improving the working efficiency.

[0008] Preferably, a guiding plate is fixedly installed at a position near the top end of the feeding port on the inner surface of the side wall of the furnace body, and the side wall of the guiding plate close to the second heating chamber is vertically downward; the height of the guiding plate is greater than the height of the feeding port.

[0009] During operation, when the material is conveyed into the interior of the furnace body through the feed inlet on the side wall of the furnace body, after the material enters the feed inlet, it is first blocked by the material guiding plate, and finally, under the guiding action of the material guiding plate, it falls back onto the inclined side wall of the furnace body and rolls downward, avoiding the situation that when the conveying speed of the external material is too high, the material no longer rolls downward along the inclined side wall of the furnace body, but breaks away from the side wall slope and falls into the upper surface of the bottom end of the furnace body in a parabola. Even some materials will first collide with the connecting block or the outer surface of the side wall of the second heating chamber and then fall onto the upper surface of the bottom end of the furnace body, thereby exacerbating the wear of the furnace body and the second heating chamber. At the same time, there is an adverse phenomenon that the space between the lower surface of the bottom end of the second heating chamber and the upper surface of the bottom end of the furnace body is not filled with materials. The setting of the material guiding plate avoids the occurrence of the above problems and improves the working efficiency and service life of the present invention; the height of the material guiding plate is greater than the height of the feed inlet, ensuring that all the materials input from the feed inlet are blocked by the material guiding plate and guided onto the inclined side wall of the furnace body, improving the working stability of the present invention.

[0010] Preferably, the side wall of the second heating chamber is parallel to the side wall of the furnace body, and the corresponding distances between the outer surface and the lower surface of the bottom end of the second heating chamber and the inner surface and the upper surface of the bottom end of the furnace body are equal.

[0011] During operation, after the space between the upper surface of the bottom end of the furnace body and the lower surface of the bottom end of the second heating chamber is filled with materials, the materials will accumulate in the space between the inner surface of the side wall of the furnace body and the outer surface of the side wall of the second heating chamber. The parallelism between the side wall of the second heating chamber and the side wall of the furnace body ensures that the distances between the side wall of the second heating chamber and the side wall of the furnace body at various positions do not change. The first heating chamber and the second heating chamber conduct uniform heat transfer to the materials therein, improving the melting rate of the materials; at the same time, the distance between the lower surface of the bottom end of the second heating chamber and the upper surface of the bottom end of the furnace body is also the same as the aforementioned distance, making the materials accumulated inside the entire furnace body heat more uniformly and further improving the working efficiency of the present invention.

[0012] Preferably, a motor rotating shaft is fixedly installed at the middle position of the upper surface of the furnace cover; the furnace cover is rotatably connected to the top end of the furnace body.

[0013] During operation, the material is conveyed into the interior of the furnace body through the feed inlet on the side wall of the furnace body. At the same time, the motor rotating shaft drives the furnace cover to rotate, and the rotation of the furnace cover drives the second heating chamber to rotate. The rotation of the second heating chamber enables this part of the material that is accidentally stuck between the inner surface of the side wall of the furnace body and the outer surface of the side wall of the second heating chamber during the rolling process due to irregular shape, etc., to move and disperse, and then fall onto the upper surface of the bottom end of the furnace body; it avoids the problem that the inside of the furnace body is not filled with materials due to the blockage between the inner surface of the side wall of the furnace body and the outer surface of the side wall of the second heating chamber, improving the working efficiency of the present invention; at the same time, since the material becomes soft when heated to near the melting temperature, the rotation of the second heating chamber plays a certain stirring role on these softened materials, improving the heat transfer efficiency, that is, further improving the working efficiency of the present invention.

[0014] Preferably, a plurality of bumps are fixedly installed on the outer surface of the side wall of the second heating chamber, and the bumps are arranged staggeredly between adjacent layers; the material of the bumps is the same as that of the second heating chamber.

[0015] During operation, the arrangement of the bumps increases the heat conduction area of the outer surface of the side wall of the second heating chamber, that is, increases the heating area of the materials in the furnace body, and improves the melting rate of the materials; at the same time, the bumps are arranged staggeredly between adjacent layers, so that the bumps are more likely to break up the stuck materials when following the rotation of the second heating chamber, so as to restore the smoothness of the materials rolling downwards, and improve the working efficiency of the present invention; at the same time, the rotation of the bumps can push the materials to the spaces on both sides below the feeding port, making the accumulation of the materials inside the furnace body more uniform, and improving the space utilization efficiency; and the bumps enhance the stirring effect on the materials that become soft when approaching the melting temperature, further improving the working efficiency of the present invention.

[0016] Preferably, the cross section of the bump is triangular, and the surface of the bump close to the furnace cover slopes downwards.

[0017] During operation, since the cross section of the bump is triangular, the area of the end of the bump close to the inner surface of the side wall of the furnace body is the smallest, that is, the friction area provided for the materials stuck between the bump and the inner surface of the side wall of the furnace body is the smallest, reducing the probability of the materials being stuck and improving the working efficiency; the surface of the bump close to the furnace cover slopes downwards, so that the molten materials on the bump can flow down along its surface and drip, avoiding part of the molten materials remaining at the joint between the bump and the outer surface of the side wall of the first heating chamber, thereby causing waste of materials; at the same time, it avoids the formation of a high-temperature resistant alumina film on the surface of the solidified materials due to the reaction with air, and finally reduces the heat conduction efficiency of the second heating chamber, improving the working stability of the present invention.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For the aluminum profile smelting furnace of the present invention, by setting the first heating chamber, the second heating chamber, the feeding port and the material guiding plate, the materials in the furnace body are heated evenly, comprehensively, inside and outside, solving the problem that the materials in the middle part of the traditional smelting furnace are not heated in time due to excessive stacking thickness during operation and always melt later, and improving the working efficiency.

[0020] 2. For the aluminum profile smelting furnace of the present invention, by setting the motor rotating shaft and the bumps, while adding materials to the furnace body from the outside, the motor rotating shaft drives the furnace cover to rotate and finally drives the second heating chamber to rotate, so that the outer surface of the side wall of the second heating chamber and the bumps break up the stuck materials during the rotation process, ensuring that the materials can smoothly roll onto the upper surface of the bottom end of the furnace body, further improving the working efficiency of the present invention.

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0027] As Figures 1 to 3 shown, an aluminum profile smelting furnace of the present invention includes a furnace body 1, a furnace cover 2, a first heating chamber 3 and a second heating chamber 4; the side wall of the furnace body 1 is inclined, and feed inlets 11 are evenly distributed at a position near the top end of the side wall of the furnace body 1; the furnace cover 2 is arranged at the top end of the furnace body 1; a connecting block 21 is fixedly installed at the middle position of the lower surface of the furnace cover 2, and the lower surface of the connecting block 21 is parallel to the bottom end of the feed inlet 11; the first heating chamber 3 is arranged at the positions of the side wall and the bottom outer surface of the furnace body 1, and the first heating chamber 3 is in contact with the furnace body 1 in a shape-matching manner; the position of the feed inlet 11 is higher than the upper surface of the top end of the first heating chamber 3; the second heating chamber 4 is fixedly installed on the lower surface of the connecting block 21, and the lower surface of the bottom end of the second heating chamber 4 is close to the middle position inside the furnace body 1.

[0028] During operation, materials are conveyed into the interior of the furnace body 1 through the feed inlet 11 on the side wall of the furnace body 1. Due to the inclination of the side wall of the furnace body 1, the materials roll down along the side wall of the furnace body 1 from the feed inlet 11 and keep rolling under the influence of gravity until they reach a position near the center of the upper surface of the bottom end of the furnace body 1. When more materials are added, the space between the upper surface of the bottom end of the furnace body 1 and the lower surface of the bottom end of the second heating chamber 4 is gradually filled with materials, and then the materials will accumulate in the space between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4. When the materials accumulate near the bottom end of the feed inlet 11, the feeding stops. Since the first heating chamber 3 wraps the outer surface of the side wall and the outer surface of the bottom end of the furnace body 1, that is, heat is transferred to the materials from the outside to the inside, and the second heating chamber 4 is wrapped by the materials inside the furnace body 1, that is, heat is transferred to the materials from the inside to the outside, the materials inside the furnace body 1 are uniformly and comprehensively heated, which speeds up the melting speed of the materials and improves the production efficiency. At the same time, the second heating chamber 4 inside the furnace body 1 occupies the materials accumulated at this position in the traditional smelting furnace, solving the problem that the part of the materials near the side wall of the furnace body 1 has been heated and melted first, but the middle part is not heated in time due to the too large stacking thickness and always becomes molten state later, further improving the working efficiency.

[0029] As an embodiment of the present invention, a material guiding plate 12 is fixedly installed at a position near the top end of the feed inlet 11 on the inner surface of the side wall of the furnace body 1, and the side wall of the material guiding plate 12 close to the second heating chamber 4 is vertically downward; the height of the material guiding plate 12 is greater than the height of the feed inlet 11.

[0030] During operation, when the materials are conveyed into the interior of the furnace body 1 through the feed inlet 11 on the side wall of the furnace body 1, the materials are first blocked by the material guiding plate 12 after entering the feed inlet 11, and finally, under the guiding action of the material guiding plate 12, they fall back onto the inclined side wall of the furnace body 1 and roll down, avoiding the situation that when the conveying speed of the external materials is too large, the materials no longer roll down along the inclined side wall of the furnace body 1, but fall into the upper surface of the bottom end of the furnace body 1 from the feed inlet 11 in a parabola, and even some materials will first collide with the connecting block 21 or the outer surface of the side wall of the second heating chamber 4 and then fall into the upper surface of the bottom end of the furnace body 1, which will further aggravate the wear of the furnace body 1 and the second heating chamber 4. At the same time, there will be a bad phenomenon that the space between the lower surface of the bottom end of the second heating chamber 4 and the upper surface of the bottom end of the furnace body 1 is not filled with materials. The setting of the material guiding plate 12 avoids the occurrence of the above problems, improves the working efficiency and service life of the present invention; the height of the material guiding plate 12 is greater than the height of the feed inlet 11, ensuring that all the materials input from the feed inlet 11 are blocked by the material guiding plate 12 and guided onto the inclined side wall of the furnace body 1, improving the working stability of the present invention.

[0031] As an embodiment of the present invention, the side wall of the second heating chamber 4 is parallel to the side wall of the furnace body 1, and the corresponding distances between the outer surface of the side wall and the lower surface of the bottom end of the second heating chamber 4 and the inner surface of the side wall and the upper surface of the bottom end of the furnace body 1 are equal.

[0032] During operation, after the space between the upper surface of the bottom end of the furnace body 1 and the lower surface of the bottom end of the second heating chamber 4 is filled with materials, the materials will accumulate in the space between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4. The side wall of the second heating chamber 4 is parallel to the side wall of the furnace body 1, so that the distance between the side wall of the second heating chamber 4 and the side wall of the furnace body 1 remains unchanged everywhere. The first heating chamber 3 and the second heating chamber 4 transfer heat to the materials therein evenly, improving the melting rate of the materials. At the same time, the distance between the lower surface of the bottom end of the second heating chamber 4 and the upper surface of the bottom end of the furnace body 1 is also the same as the aforementioned distance, that is, the materials accumulated inside the entire furnace body 1 are heated more evenly, further improving the working efficiency of the present invention.

[0033] As an embodiment of the present invention, a motor rotating shaft 22 is fixedly installed at the middle position of the upper surface of the furnace cover 2; the furnace cover 2 is rotatably connected to the top end of the furnace body 1.

[0034] During operation, the materials are conveyed into the interior of the furnace body 1 from the feed port 11 on the side wall of the furnace body 1. At the same time, the motor rotating shaft 22 drives the furnace cover 2 to rotate, and the rotation of the furnace cover 2 drives the second heating chamber 4 to rotate. The rotation of the second heating chamber 4 enables this part of the materials that are stuck between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4 due to accidental reasons such as irregular shapes during the rolling process to move and disperse, and then fall onto the upper surface of the bottom end of the furnace body 1. It avoids the problem that the interior of the furnace body 1 is not filled with materials due to blockage between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4, improving the working efficiency of the present invention. At the same time, since the materials become soft when heated to near the melting temperature, the rotation of the second heating chamber 4 plays a certain stirring role on these softened materials, improving the heat transfer efficiency, that is, further improving the working efficiency of the present invention.

[0035] As an embodiment of the present invention, a plurality of convex blocks 41 are fixedly installed on the outer surface of the side wall of the second heating chamber 4, and the convex blocks 41 are staggered between adjacent layers; the material of the convex blocks 41 is the same as that of the second heating chamber 4.

[0036] During operation, the setting of the convex blocks 41 increases the heat conduction area of the outer surface of the side wall of the second heating chamber 4, that is, increases the heating area of the materials inside the furnace body 1, improving the melting rate of the materials. At the same time, the convex blocks 41 are staggered between adjacent layers, making it easier for the convex blocks 41 to break up the stuck materials when following the rotation of the second heating chamber 4 to restore the smoothness of the materials rolling downward, improving the working efficiency of the present invention. At the same time, the rotation of the convex blocks 41 can push the materials to the spaces on both sides below the feed port 11, making the accumulation of the materials inside the furnace body 1 more uniform and improving the space utilization efficiency. And the convex blocks 41 enhance the stirring effect on the materials that become soft when approaching the melting temperature, further improving the working efficiency of the present invention.

[0037] As an embodiment of the present invention, the cross-section of the bump 41 is triangular, and the surface of the bump 41 close to the furnace cover 2 slopes downward.

[0038] During operation, since the cross-section of the bump 41 is triangular, the area of one end of the bump 41 close to the inner surface of the side wall of the furnace body 1 is the smallest, that is, the friction area provided for the material stuck between the bump 41 and the inner surface of the side wall of the furnace body 1 is the smallest, reducing the probability of the material getting stuck and improving the working efficiency; the surface of the bump 41 close to the furnace cover 2 slopes downward, so that the molten material on the bump 41 can flow downward along its surface and drip, avoiding part of the molten material remaining at the joint between the bump 41 and the outer surface of the side wall of the first heating chamber 3, thereby causing waste of the material; at the same time, it avoids the surface of the material reacting with air after solidification to generate a high-temperature resistant alumina film, ultimately reducing the heat conduction efficiency of the second heating chamber 4 and improving the working stability of the present invention.

[0039] The specific working process is as follows:

[0040] Materials are conveyed into the interior of the furnace body 1 from the feed inlet 11 on the side wall of the furnace body 1. After the materials enter the feed inlet 11, they are first blocked by the guiding plate 12, and finally, under the guiding action of the guiding plate 12, they fall back onto the inclined side wall of the furnace body 1 and roll downward, avoiding the situation that when the conveying speed of external materials is too high, the materials no longer roll downward along the inclined side wall of the furnace body 1, but break away from the side wall slope and fall into the upper surface of the bottom end of the furnace body 1 in a parabola. Even some materials will first collide with the connecting block 21 or the outer surface of the side wall of the second heating chamber 4 and then fall onto the upper surface of the bottom end of the furnace body 1, thereby exacerbating the wear of the furnace body 1 and the second heating chamber 4. At the same time, there will be an adverse phenomenon that the space between the lower surface of the bottom end of the second heating chamber 4 and the upper surface of the bottom end of the furnace body 1 is not filled with materials; after the space between the upper surface of the bottom end of the furnace body 1 and the lower surface of the bottom end of the second heating chamber 4 is filled with materials, the materials will accumulate in the space between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4. The parallelism between the side wall of the second heating chamber 4 and the side wall of the furnace body 1 ensures that the distance between the side wall of the second heating chamber 4 and the side wall of the furnace body 1 remains unchanged everywhere. The first heating chamber 3 and the second heating chamber 4 transfer heat to the materials therein evenly, improving the melting rate of the materials; at the same time, the distance between the lower surface of the bottom end of the second heating chamber 4 and the upper surface of the bottom end of the furnace body 1 is also the same as the aforementioned distance, making the materials accumulated inside the entire furnace body 1 receive more uniform heat, further improving the working efficiency of the present invention; while the materials are conveyed into the interior of the furnace body 1 from the feed inlet 11 on the side wall of the furnace body 1, the motor rotating shaft 22 drives the furnace cover 2 to rotate. The rotation of the furnace cover 2 drives the second heating chamber 4 to rotate. The rotation of the second heating chamber 4 enables this part of the materials that are accidentally stuck between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4 during the rolling process due to irregular shapes, etc., to move and disperse, and then fall onto the upper surface of the bottom end of the furnace body 1; it avoids the problem that the inside of the furnace body 1 is not filled with materials due to the blockage between the inner surface of the side wall of the furnace body 1 and the outer surface of the side wall of the second heating chamber 4, improving the working efficiency of the present invention; at the same time, since the materials become soft when heated to near the melting temperature, the rotation of the second heating chamber 4 plays a certain stirring role on these softened materials, improving the heat transfer efficiency, that is, further improving the working efficiency of the present invention; and the setting of the convex blocks 41 increases the heat conduction area of the outer surface of the side wall of the second heating chamber 4, that is, increases the heating area of the materials inside the furnace body 1, improving the melting rate of the materials; at the same time, the convex blocks 41 are arranged staggeredly between adjacent layers, making it easier for the convex blocks 41 to break up the stuck materials when following the rotation of the second heating chamber 4 to restore the smoothness of the materials rolling downward, improving the working efficiency of the present invention; and the convex blocks 41 enhance the stirring effect on the materials that become soft when approaching the melting temperature, further improving the working efficiency of the present invention; since the cross-section of the convex blocks 41 is triangular, the area of the end of the convex blocks 41 close to the inner surface of the side wall of the furnace body 1 is the smallest, that is, the friction area provided for the materials stuck between the convex blocks 41 and the inner surface of the side wall of the furnace body 1 is the smallest, reducing the probability of the materials being stuck and improving the working efficiency;The surface of the bump 41 close to the furnace cover 2 slopes downward, so that the molten material on the bump 41 can flow downward along its surface and drip, avoiding part of the molten material remaining at the joint between the bump 41 and the outer surface of the side wall of the first heating chamber 3, thereby causing waste of materials; at the same time, it avoids the reaction of the surface of the solidified material with air to generate a high-temperature-resistant alumina film, ultimately reducing the heat conduction efficiency of the second heating chamber 4 and improving the working stability of the present invention; since the first heating chamber 3 wraps the outer surface of the side wall and the bottom outer surface of the furnace body 1 externally, that is, transferring heat to the material from the outside to the inside, and the second heating chamber 4 is wrapped by the material inside the furnace body 1, that is, transferring heat to the material from the inside to the outside, the material inside the furnace body 1 is heated evenly and comprehensively, accelerating the melting speed of the material and improving the production efficiency; in the aluminum profile smelting furnace of the present invention, by setting the first heating chamber 3, the second heating chamber 4, the feed inlet 11 and the material guiding plate 12, the material in the furnace body 1 is heated evenly and comprehensively inside and outside, solving the problem that the material in the middle part of the traditional smelting furnace is not heated in time due to excessive stacking thickness and always melts later, and improving the working efficiency; by setting the motor rotating shaft 22 and the bump 41, while adding material to the furnace body 1 externally, the motor rotating shaft 22 drives the furnace cover 2 to rotate and finally drives the second heating chamber 3 to rotate, so that the outer surface of the side wall of the second heating chamber 3 and the bump 41 disperse the stuck material during the rotation process, ensuring that the material can smoothly roll onto the upper surface of the bottom end of the furnace body 1, and further improving the working efficiency of the present invention.

After entering the feed port (11), the material is first blocked by the guide plate (12) and finally falls back onto the inclined side wall of the furnace body (1) under the guidance of the guide plate (12) and rolls downward, thereby preventing the material from no longer rolling downward along the inclined side wall of the furnace body (1) when the external material conveying speed is too high, but from breaking away from the inclined surface of the side wall and falling from the feed port (11) in a parabola onto the upper surface of the bottom end of the furnace body (1). Part of the material may even collide with the connecting block (21) or the outer surface of the side wall of the second heating chamber (4) before falling onto the upper surface of the bottom end of the furnace body (1), thereby aggravating the wear of the furnace body (1) and the second heating chamber (4), and causing the lower surface of the bottom end of the second heating chamber (4) to collide with the lower surface of the bottom end of the furnace body (1). The undesirable phenomenon that the space between the upper surface of the bottom end of the furnace body (1) is not filled with materials; after the space between the upper surface of the bottom end of the furnace body (1) and the lower surface of the bottom end of the second heating chamber (4) is filled with materials, the materials will accumulate in the space between the inner surface of the side wall of the furnace body (1) and the outer surface of the side wall of the second heating chamber (4); the side wall of the second heating chamber (4) is parallel to the side wall of the furnace body (1), so that the distance between the side wall of the second heating chamber (4) and the side wall of the furnace body (1) at any point will not change, and the first heating chamber (3) and the second heating chamber (4) transfer heat to the materials therein uniformly, thereby improving the melting rate of the materials; at the same time, the distance between the lower surface of the bottom end of the second heating chamber (4) and the upper surface of the bottom end of the furnace body (1) is also the same as the aforementioned distance, so that the materials accumulated inside the entire furnace body (1) are heated more The material is uniformly fed into the furnace body (1) from the feed port (11) on the side wall of the furnace body (1), while the motor shaft (22) drives the furnace cover (2) to rotate, and the rotation of the furnace cover (2) drives the second heating chamber (4) to rotate, and the rotation of the second heating chamber (4) allows the material that is stuck between the inner surface of the side wall of the furnace body (1) and the outer surface of the side wall of the second heating chamber (4) during the rolling process due to accidental reasons such as irregular shape to be moved and dispersed, and then falls to the upper surface of the bottom end of the furnace body (1); the problem of the furnace body (1) not being filled with material due to the blockage between the inner surface of the side wall of the furnace body (1) and the outer surface of the side wall of the second heating chamber (4) is avoided, thereby improving the working efficiency of the present invention; at the same time, since the material is heated to The materials will become soft when approaching the melting temperature, and the rotation of the second heating chamber (4) has a certain stirring effect on the softened materials, thereby improving the heat transfer efficiency, that is, further improving the working efficiency of the present invention; and the arrangement of the protrusions (41) increases the heat conduction area of ​​the outer surface of the side wall of the second heating chamber (4), that is, increases the heating area of ​​the materials in the furnace body (1), and improves the melting rate of the materials; at the same time, the protrusions (41) are staggered between two adjacent layers, so that the protrusions (41) are more likely to break up the stuck materials when following the rotation of the second heating chamber (4), so as to restore the smoothness of the materials rolling down, thereby improving the working efficiency of the present invention; and the protrusions (41) enhance the stirring effect on the materials that become soft when approaching the melting temperature, thereby further improving the working efficiency of the present invention;Since the cross-section of the bump (41) is triangular, the area of one end of the bump (41) close to the inner surface of the side wall of the furnace body (1) is the smallest, that is, the friction area provided for the material stuck between the bump (41) and the inner surface of the side wall of the furnace body (1) is the smallest, reducing the probability of the material being stuck and improving the working efficiency; the surface of the bump (41) close to the furnace cover (2) slopes downward, so that the molten material on the bump (41) can flow downward along its surface and drip, avoiding part of the molten material remaining at the joint between the bump (41) and the outer surface of the side wall of the first heating chamber (3), thereby causing waste of the material; at the same time, it avoids the formation of a high-temperature resistant alumina film on the surface of the material after solidification due to reaction with air, ultimately reducing the heat conduction efficiency of the second heating chamber (4) and improving the working stability of the present invention; since the first heating chamber (3) wraps the outer surface of the side wall and the outer surface of the bottom end of the furnace body (1) from the outside, that is, transfers heat to the material from the outside to the inside, and the second heating chamber (4) is wrapped by the material inside the furnace body (1), that is, transfers heat to the material from the inside to the outside, the material inside the furnace body (1) is heated evenly and comprehensively, accelerating the melting speed of the material.
