Description

Technical Field

[0001] This utility model relates to the field of smelting and impurity removal technology, and in particular to an aluminum profile processing smelting and impurity removal device. Background Technology

[0002] Aluminum profiles are metal materials with specific cross-sectional shapes formed by plastic processing of aluminum alloys, such as extrusion, rolling, and stretching. During the processing, aluminum ingots are melted and alloying elements are added to cast them into cylindrical rods. The rods are held at 550℃ for 8-12 hours to eliminate component segregation and improve plasticity. The rods are then heated to 450-500℃ and extruded through a die. After extrusion, they are immediately cooled to fix the solid solution structure.

[0003] All raw materials need to be baked at 150℃ for 2 hours to remove surface moisture. Materials used for smelting require shot blasting to remove oxide scale and cleaning. During smelting, impurities such as hydrogen, oxides, and metallic slag are present. The impurity removal process mainly includes: injecting Cl2 into the melt; bubbles adsorb H2 and float to the surface; multi-layered foam ceramics can intercept particles; chlorine reacts with sodium to form NaCl, which floats to the surface. Slag floating on the molten material during impurity removal needs to be removed, i.e., slag skimming. This process is mostly done manually, which is inefficient, and the high-temperature environment results in a harsh working environment. There is a possibility of spillage during the cleaning of high-temperature slag, which not only pollutes the environment but also causes burns if it adheres to the skin, posing a safety hazard. Therefore, those skilled in the art provide an aluminum profile processing smelting impurity removal device to solve the problems mentioned in the background art. Utility Model Content

[0004] 1. Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an aluminum profile processing, smelting, and impurity removal device, comprising a support frame, a smelting furnace, a support ring, a support tube, and a motor. The smelting furnace is housed inside the support frame, and the support ring is located on the upper side of the smelting furnace. Two sets of hydraulic rods with their telescopic ends connected to the lower end of the support ring are located inside the support frame. One end of the smelting furnace has an inwardly recessed discharge groove. Symmetrically distributed top seats are located on the inner wall of the support ring, and a motor is located on the upper end of the top seats. A gear is located at the output end of the motor. A support tube is located at the center of the smelting furnace, and an insert is located inside the upper end of the support tube. Two sets of symmetrically distributed stirring rods are located on the outer wall of the lower end of the support tube. A gear ring that meshes with the gear is sleeved on the outer wall of the upper end of the support tube, and a scraper is located on the outer wall of the support tube.

[0007] Furthermore, the lower inner wall of the support frame is provided with a receiving groove whose upper inner wall is inclined and located below the discharge groove, and the lower inner wall of the discharge groove is provided with a guide surface, the lower part of the guide surface facing the outside of the smelting furnace.

[0008] Specifically, the receiving tank receives and guides the scum discharged from the discharge tank, and the flowability of the scum inside the discharge tank is improved by the guiding surface.

[0009] Furthermore, the outer wall of the support tube is fitted with a ring rail in an annular shape, and the inner wall of the top seat is provided with symmetrically distributed ring seats. The inner wall of the ring seats is rotatably mounted with balls arranged in an annular array and rolling against the inner wall of the ring rail.

[0010] Specifically, the balls are rotated and supported inside the ring rail, and the support tube is rotated and supported through the ring seat. During rotation, the balls reduce friction and resistance.

[0011] Furthermore, a sealed bearing is embedded in the inner wall of the upper end of the support tube, and the insertion tube is rotatably inserted into the sealed bearing;

[0012] Specifically, the insertion tube rotates inside the sealed bearing, and when the support tube rotates, the sealed bearing prevents the insertion tube from rotating with the support tube.

[0013] Furthermore, a tank is provided at one end of the support frame, a delivery pump is provided at one end of the tank, a suction pipe is connected to the output end of the tank at the suction end of the delivery pump, and a flexible hose connected to the insertion tube 21 is provided at the delivery end of the delivery pump.

[0014] Specifically, the tank stores Cl2, which is then drawn in by a transfer pump, transported through a hose to the insertion tube and into the support tube, and discharged through the bottom of the support tube in the molten aluminum.

[0015] Furthermore, the lower surface and the lower inner wall of the smelting furnace are both semi-circular, and the outer wall of the smelting furnace is provided with symmetrically distributed rotating shafts that are rotatably installed inside the support frame. The front end of the support frame is provided with a motor II whose output end is connected to the rotating shaft.

[0016] Specifically, when the second drive shaft of the motor rotates, it drives the smelting furnace to rotate, causing the smelting furnace to flip over, which facilitates the pouring of molten aluminum. The bottom arc effectively passes through the discharge trough, and the inner wall arc improves the smoothness of molten aluminum discharge.

[0017] 2. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] In this invention, aluminum ingots are added to a smelting furnace, heated and melted, and alloying elements are added. During this process, a motor drives a gear to push a gear ring, which in turn drives a support tube to rotate. The support tube drives a stirring rod to stir the hot molten aluminum. During this process, Cl2 is injected into the support tube, and bubbles adsorb H2 and float to the surface. A layer of covering agent is sprinkled on the molten aluminum to reduce air contact, prevent oxidation of the molten aluminum, and absorb moisture from the air. At the same time, it adsorbs the floating oxide slag. Argon bubbles float in the molten aluminum and increase their contact with the molten aluminum through stirring. Because there is almost no hydrogen in the argon bubbles, hydrogen will diffuse in and float to the surface of the molten aluminum along with them.

[0020] During this process, stirring increases the diffusion of argon gas in the molten aluminum. When slag removal is required, the scraper located on the outer wall of the support tube descends to contact the surface of the molten aluminum. The rotation of the support tube drives the scraper to push the slag. When passing through the discharge tank, the scraper squeezes and lifts the inner wall of the melting furnace, scraping off the slag. The scraper continues to rotate multiple times to achieve thorough removal of the slag, avoiding manual slag removal and improving the safety of impurity removal during the aluminum profile melting and processing. At the same time, the combination of slag removal and slag removal equipment makes the structure compact and reduces the space occupied by the equipment.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Please see Figure 1-6As shown, this embodiment is an aluminum profile processing, smelting, and impurity removal device, including a support frame 1, a smelting furnace 2, a support ring 3, a support pipe 4, and a motor 8. The smelting furnace 2 is installed inside the support frame 1, and the support ring 3 is installed on the upper side of the smelting furnace 2. Two sets of hydraulic rods 7 with telescopic ends connected to the lower end of the support ring 3 are installed inside the support frame 1. One end of the smelting furnace 2 is provided with an inwardly recessed discharge groove 11. The inner wall of the support ring 3 is provided with symmetrically distributed top seats 14. The upper end of the top seat 14 is provided with a motor 8. The output end of the motor 8 is provided with a gear 18. The center of the smelting furnace 2 is provided with a tube 21 inside the upper end of the support pipe 4. Two sets of symmetrically distributed stirring rods 19 are provided on the outer wall of the lower end of the support pipe 4. A gear ring 24 that meshes with the gear 18 is sleeved on the outer wall of the upper end of the support pipe 4. A scraper 20 is provided on the outer wall of the support pipe 4.

[0037] The lower inner wall of the support frame 1 is provided with a receiving groove 16 whose upper inner wall is inclined and located below the discharge groove 11. The lower inner wall of the discharge groove 11 is provided with a guide surface 13, and the lower part of the guide surface 13 faces the outside of the smelting furnace 2.

[0038] The outer wall of the support tube 4 is fitted with a ring rail 22 in an annular shape, and the inner wall of the top seat 14 is provided with symmetrically distributed ring seats 15. The inner wall of the ring seats 15 is rotatably installed with balls 17 arranged in an annular array and rolling against the inner wall of the ring rail 22.

[0039] A sealed bearing 25 is embedded in the inner wall of the upper end of the support tube 4, and the insertion tube 21 is rotatably inserted into the sealed bearing 25.

[0040] One end of the support frame 1 is provided with a tank 5, and the other end of the tank 5 is provided with a delivery pump 6. The suction end of the delivery pump 6 is connected to the output end of the tank 5 by a suction pipe 23, and the delivery end of the delivery pump 6 is provided with a flexible hose 9 connected to the insertion pipe 21.

[0041] The lower surface and lower inner wall of the smelting furnace 2 are both semi-circular. The outer wall of the smelting furnace 2 is provided with symmetrically distributed rotating shafts 12 that are rotatably installed inside the support frame 1. The front end of the support frame 1 is provided with a motor 10 whose output end is connected to the rotating shafts 12.

[0042] In this embodiment, aluminum ingots and alloy raw materials are baked at 150°C for 2 hours to remove moisture, and the oxide scale on the surface of the smelting furnace 2 is removed by shot blasting. The raw materials are put into the smelting furnace 2, and 50% KCl and 50% NaCl are sprinkled as covering agents to isolate the air. The raw materials are heated to 700-750°C to melt them. The motor 8 is started to drive the gear 18, which drives the gear ring 24 to rotate the support tube 4. The delivery pump 6 draws Cl2 from the tank 5 and sprays it into the aluminum liquid through the hose 9, the insertion tube 21, and the support tube 4. The rotating stirring rod 19 breaks up the bubbles and expands the gas-liquid contact surface. Hydrogen diffuses into the bubbles and floats up.

[0043] After the slag accumulates, the hydraulic rod 7 presses down the support ring 3, causing the scraper 20 to contact the surface of the molten aluminum. The support tube 4 continues to rotate, and the scraper 20 pushes the slag towards the discharge trough 11 on the inner wall of the smelting furnace 2. When the scraper 20 reaches the discharge trough 11, it is lifted by the pressure of the inner wall, and the slag is completely scraped into the trough. The slag flows into the receiving trough 16 through the guide surface 13 for centralized recycling. After the impurity removal is completed, the motor 2 10 drives the rotating shaft 12 to rotate the smelting furnace 2. The slag in the receiving trough 16 is cooled and then uniformly processed. The equipment is then reset and ready for use.

[0044] When bubbles rise in the molten aluminum, they form a low-pressure zone, and H2 diffuses into the bubbles. After the bubbles reach the upper surface of the molten aluminum, they burst, carrying out hydrogen. The stirring rod 19 enhances the turbulence, improves the uniformity of bubble distribution, and increases the hydrogen removal efficiency. The scraper 20 contacts the scum at the upper end of the molten aluminum and generates a centripetal thrust when rotating, which pushes the scum to move in a directional manner. The inner walls of the receiving tank 16 and the discharge tank 11 are covered with a high-temperature resistant ceramic coating to prevent scum from adhering.

[0045] Traditional processes involve dangerous manual slag removal, slag spillage and pollution, and fragmented equipment functions. The scraper 20 automatically scrapes slag and is hydraulically positioned, avoiding high-temperature burns and eliminating safety hazards. The rotating jet frame mechanically stirs and enhances gas-liquid mass transfer, resulting in better hydrogen removal and improved cleanliness of the working environment. The support pipe 4 simultaneously performs gas injection, melt stirring, and slag removal, reducing the equipment's footprint and energy consumption. The insertion pipe 21 is connected to the rotating support pipe 4 via a sealed bearing 25 to prevent leakage during Cl2 transport. The principle of air flotation separation combined with directional scraping thoroughly removes hydrogen, oxides, and alkali metal impurities. Its integrated design improves the safety and impurity removal efficiency in high-temperature environments.
