Description

Technical Field

[0001] This application relates to the field of aluminum production technology, and in particular to a homogenizing furnace for aluminum rods. Background Technology

[0002] High-purity aluminum rods contain a high amount of aluminum, but still contain small amounts of magnesium silicide and iron. Therefore, homogenization is an essential process for aluminum rods. Aluminum rod homogenization furnaces generally use electric or natural gas heating. By heating the air inside the furnace, the heated furnace gas comes into contact with the surface of the aluminum rod under the action of the circulating fan inside the furnace to exchange heat, so that the aluminum rod continuously absorbs heat until the temperature of the aluminum rod reaches the required range of the process, thus achieving the purpose of heating and maintaining the temperature of the aluminum rod.

[0003] Currently, most homogenizing furnaces use a trolley-type homogenizing heater to heat and homogenize aluminum rods. When homogenization heating of the aluminum rods is required, the rods are placed on a trolley, which is then pushed into the heating chamber of the homogenizing furnace. Once homogenization is complete, the furnace chamber is opened, and the trolley is pulled out. The homogenizing furnace is stopped during both the pushing and pulling of the trolley into and out of the furnace chamber to allow the internal temperature to drop before the trolley can be moved. Summary of the Invention

[0004] In order to enable the feeding and discharging of aluminum rods without shutting down the machine, this application discloses an aluminum rod homogenizing heating furnace.

[0005] The aluminum rod homogenizing heating furnace provided in this application adopts the following technical solution:

[0006] A homogenizing furnace for aluminum rods includes a furnace body, a feeding mechanism, and a discharging mechanism. The furnace body has a heating chamber inside, and an inlet and an outlet connecting the heating chamber to the outside. The feeding mechanism is connected to the inlet, and the discharging mechanism is connected to the outlet. A horizontally arranged rotating cylinder is disposed inside the heating chamber, rotatably connected within it. A heating space is provided between the rotating cylinder and the wall of the heating chamber. The furnace body is equipped with a driving device to drive the rotating cylinder to rotate. Along the cylinder wall... Multiple dropping platforms are spaced apart in a circular direction. Aluminum bars entering the heating furnace from the feed inlet can fall onto the dropping platforms. Each dropping platform is equipped with a clamping claw, one end of which is hinged to the dropping platform. A torsion spring is provided between the clamping claw and the dropping platform. Under the action of the torsion spring, the clamping claw rotates away from the dropping platform. When the dropping platform rotates counterclockwise from the feed inlet, the clamping claw can clamp and fix the aluminum bars on the dropping platform. When the dropping platform rotates to the discharge outlet, the clamping claw releases the aluminum bars under the action of the torsion spring, allowing the aluminum bars to enter the discharge outlet.

[0007] By adopting the above technical solution, when the aluminum rod is heated and homogenized, the aluminum rod fed into the heating furnace through the feed port falls onto the unloading platform that rotates to the feed port. As the rotating drum rotates, the clamping claws press and fix the aluminum rod on the unloading platform, and drive the aluminum rod to gradually move towards the position of the discharge port. During the process of the aluminum rod moving from the feed port to the discharge port, the heating furnace heats the aluminum rod. When the aluminum rod rotates to the discharge port, the clamping claws release the aluminum rod, causing the aluminum rod to roll into the discharge port and be discharged. Thus, the feeding and unloading of aluminum rods can be completed without stopping the machine.

[0008] Optionally, the feeding mechanism includes a feeding channel fixed to the outside of the heating furnace body, a gate is provided between the feeding channel and the heating furnace body, the gate is slidably connected between the feeding channel and the feed inlet, and a driving member is provided on the heating furnace body to drive the gate to move vertically. When the gate is raised, the feeding channel is connected to the feed inlet, and when the gate is lowered, the feeding channel is disconnected from the feed inlet.

[0009] By adopting the above technical solution, the connection or disconnection between the feeding channel and the feeding port can be controlled by raising and lowering the gate. When it is not necessary to feed material into the heating furnace, the gate will disconnect the feeding port and the feeding channel, so that the heat inside the heating furnace is not easily discharged from the feeding port, thereby reducing the heat loss of the heating furnace.

[0010] Optionally, the discharge mechanism includes a discharge channel, which includes an inclined discharge section and a horizontally arranged cooling section. The end of the discharge section connected to the heating furnace body gradually decreases towards the end away from the heating furnace body.

[0011] By adopting the above technical solution, the aluminum rod discharged from the discharge port rolls down through the discharge section into the interior of the cooling section for cooling.

[0012] Optionally, a cooling fan is provided at the top of the interior of the cooling section.

[0013] By adopting the above technical solution, the cooling fan blows air into the interior of the cooling section, thereby accelerating the cooling efficiency of the aluminum rod.

[0014] Optionally, a roller is provided on the outer side of the free end of the clamping claw, and an elastic telescopic rod is provided between the roller and the clamping claw. One end of the elastic telescopic rod is connected to the roller, and the other end of the elastic telescopic rod is connected to the clamping claw.

[0015] By adopting the above technical solution, when the rotating cylinder rotates, the rollers abut against the wall of the heating furnace, and the free end of the clamping claw gradually moves closer to the unloading platform to press and fix the aluminum rod on the unloading platform. At this time, the elastic telescopic rod is in a compressed state.

[0016] Optionally, there may be multiple clamping claws, and adjacent clamping claws may be connected by a connecting rod.

[0017] By adopting the above technical solution, the connecting rod connects the adjacent clamping claws, so that the rotation of the clamping claws can be synchronized, avoiding the situation where one of the clamping claws cannot release the aluminum rod.

[0018] Optionally, a discharge rod is provided inside the heating furnace above the discharge port, and an annular groove is provided on the rotating cylinder along the circumferential direction. One end of the discharge rod is fixed to the wall of the heating furnace, and the other end extends into the annular groove. The end of the discharge rod connected to the wall of the heating furnace is higher than the end extending into the annular groove, and the end of the discharge rod extending into the annular groove is horizontally opposite to the discharge port.

[0019] By adopting the above technical solution, when the aluminum rod rotates to the discharge port, the aluminum rod abuts against the unloading top rod. The position of the unloading top rod is fixed. As the rotating drum rotates, the unloading top rod pushes the aluminum rod to move towards the discharge port, ensuring that the aluminum rod slides from the dropping platform into the discharge port.

[0020] Optionally, the rotating cylinder includes an outer cylinder and a central shaft. The outer cylinder houses the central shaft, and the outer cylinder and the central shaft are coaxially arranged. The outer cylinder and the central shaft are connected by multiple support frames.

[0021] By adopting the above technical solution, the weight of the rotating cylinder can be reduced.

[0022] Optionally, the feed inlet and the discharge outlet are located on the same side wall of the heating furnace body, and the feed inlet and the discharge outlet are arranged vertically.

[0023] By adopting the above technical solution, the feed inlet and discharge outlet are set on the same side wall, so that the aluminum rod travels almost around the entire circumference in the heating furnace, allowing the aluminum rod to be heated as much as possible.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the aluminum rod is heated and homogenized, the aluminum rod fed into the heating furnace through the feed port falls onto the unloading platform that rotates to the feed port. As the rotating drum rotates, the clamping claws clamp and fix the aluminum rod on the unloading platform, and drive the aluminum rod to gradually move towards the position of the discharge port. During the process of the aluminum rod moving from the feed port to the discharge port, the heating furnace heats the aluminum rod. When the aluminum rod rotates to the discharge port, the clamping claws release the aluminum rod, causing the aluminum rod to roll into the discharge port and be discharged. This allows the aluminum rod to be loaded and unloaded without stopping the machine.

[0026] 2. When the aluminum rod rotates to the discharge port, the aluminum rod abuts against the unloading top rod. The position of the unloading top rod is fixed. As the rotating drum rotates, the unloading top rod pushes the aluminum rod to move towards the discharge port, ensuring that the aluminum rod slides from the dropping platform into the discharge port.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses an aluminum rod homogenizing furnace.

[0037] Reference Figure 1 The aluminum rod homogenizing heating furnace includes a heating furnace body 1, a feeding mechanism 2 for feeding aluminum rods into the heating furnace body 1, and a discharging mechanism 3 for discharging the aluminum rods after they have been heated and homogenized in the heating furnace body 1.

[0038] Reference Figure 1 , Figure 2 The heating furnace body 1 has a heating furnace chamber 11 inside, which is used to heat and homogenize the aluminum rods. The feeding mechanism 2 and the discharging mechanism 3 are both connected to the heating furnace chamber 11. A rotating cylinder 12 is rotatably connected inside the heating furnace chamber 11, and the rotating cylinder 12 is arranged laterally. The heating furnace chamber 11 is cylindrical in shape, and the rotating cylinder 12 is coaxially arranged with the heating furnace chamber 11, with a space between the rotating cylinder 12 and the wall of the heating furnace chamber 11. The space between the rotating cylinder 12 and the wall of the heating furnace chamber 11 is the heating space for heating the aluminum rods.

[0039] Reference Figure 3 , Figure 4 A drive motor 13 is installed at one end of the rotating cylinder 12 in the axial direction, and the drive motor 13 is mounted on the outer surface of the heating furnace body 1. The motor shaft of the drive motor 13 passes through the side wall of the heating furnace body 1 and is connected to the rotating cylinder 12. When the drive motor 13 is started, the motor shaft of the drive motor 13 rotates, thereby driving the rotating cylinder 12 to rotate synchronously.

[0040] A feed inlet 14 and a discharge outlet 15, which are connected to the heating furnace chamber 11, are provided on the side wall of the heating furnace body 1 facing the rotating cylinder 12. The feed inlet 14 is located at the three o'clock position of the rotating cylinder 12, and the discharge outlet 15 is located below the feed inlet 14. Both the feed inlet 14 and the discharge outlet 15 connect the heating furnace chamber 11 to the outside of the heating furnace body 1.

[0041] The rotating cylinder 12 includes a coaxially arranged central shaft 121 and an outer cylinder 122, with the outer cylinder 122 housing the central shaft 121. Both ends of the central shaft 121 are rotatably connected to the heating furnace body 1. The motor shaft of the drive motor 13 is coaxial with and fixedly connected to the central shaft 121. A plurality of support frames 123 are arranged between the central shaft 121 and the outer cylinder 122. One end of the support frame 123 is welded and fixed to the central shaft 121, and the other end of the support frame 123 is welded and fixed to the outer cylinder 122.

[0042] Multiple unloading platforms 124 are provided on the outer surface of the outer cylinder 122, extending along the axial direction of the outer cylinder 122. These platforms are equidistant from each other along the circumference of the outer cylinder 122. The unloading platforms 124 are welded to or integrally formed with the outer cylinder 122. When the unloading platform 124 rotates with the outer cylinder 122 to the three o'clock position in the heating furnace 11, its surface is horizontal and flush with the bottom of the feed inlet 14. When the aluminum rod enters the heating furnace 11 through the feed inlet 14, it rolls onto the unloading platform 124 located at the three o'clock position.

[0043] Reference Figure 4 , Figure 5 Each unloading platform 124 is provided with multiple clamping claws 125 spaced apart along the axial direction of the outer cylinder 122. One end of the clamping claw 125 is hinged to the side of the unloading platform 124 near the outer cylinder 122, and the other end of the clamping claw 125 is a free end extending towards the side of the unloading platform 124 away from the outer cylinder 122. A torsion spring 126 is installed between the clamping claw 125 and the unloading platform 124. The torsion spring 126 applies pressure to the clamping claw 125, causing the clamping claw 125 to rotate in the direction away from the unloading platform 124.

[0044] Reference Figure 6 The straight-line distance between the free end of the clamping claw 125 and the hinged end of the clamping claw 125 is less than the distance between the outer cylinder 122 and the wall of the heating furnace 11, so that the clamping claw 125 can rotate in the heating space between the outer cylinder 122 and the wall of the heating furnace 11.

[0045] A roller 127 is provided on the outer side of the free end of the clamping claw 125. An elastic telescopic rod 128 is provided between the roller 127 and the clamping claw 125. One end of the elastic telescopic rod 128 is connected to the roller 127, and the other end of the elastic telescopic rod 128 is fixed to the clamping claw 125. The roller 127 is rotatably connected to the elastic telescopic rod 128.

[0046] When the elastic telescopic rod 128 is in a state without external force, the distance between the side of the roller 127 facing away from the rotating cylinder 12 and the rotating cylinder 12 is greater than the distance between the rotating cylinder 12 and the wall of the heating furnace 11. When the elastic telescopic rod 128 is in a compressed state under the action of external force, the distance between the side of the roller 127 facing away from the rotating cylinder 12 and the rotating cylinder 12 can be less than the distance between the rotating cylinder 12 and the wall of the heating furnace 11.

[0047] When the aluminum rod is on the dropping table 124, the roller 127 abuts against the wall of the heating furnace 11, and the clamping claw 125 clamps and fixes the aluminum rod on the dropping table 124. At this time, the elastic telescopic rod 128 is in a compressed state.

[0048] The top of the end of the feed inlet 14 that is connected to the heating furnace chamber 11 is provided with an arc corner 141.

[0049] When the discharge platform 124 is located at the three o'clock position in the heating furnace 11, the free end of the clamping claw 125 separates from the discharge platform 124 under the action of the torsion spring 126. At this time, the roller 127 on the clamping claw 125 abuts against the surface of the arc corner 141. After the aluminum rod enters the heating furnace 11 from the feed port 14, it rolls onto the discharge platform 124. As the rotating cylinder 12 rotates counterclockwise, the roller 127 travels along the arc surface of the arc corner 141 and gradually abuts against the furnace wall of the heating furnace 11. When the roller 127 has completely reached the furnace wall of the heating furnace 11, the clamping claw 125 presses and fixes the aluminum rod onto the discharge platform 124.

[0050] When the unloading platform 124 rotates to the discharge port 15, the clamping claw 125 first disengages from the wall of the heating furnace 11. Under the action of the torsion spring 126, the clamping claw 125 rotates away from the unloading platform 124, thereby releasing the aluminum rod. At this time, the platform surface of the unloading platform 124 is an inclined platform surface, and the aluminum rod rolls down along the platform surface of the unloading platform 124 into the discharge port 15 and is discharged.

[0051] Reference Figure 4 In order to ensure the synchronization of the rotation of the clamping claws 125 on the same unloading platform 124, a connecting rod 1251 is provided between adjacent clamping claws 125. One end of the connecting rod 1251 is fixedly connected to one of the clamping claws 125, and the other end of the connecting rod 1251 is fixedly connected to the other clamping claw 125.

[0052] To ensure the aluminum rods can smoothly slide from the discharge table 124 into the discharge port 15, a discharge rod 4 is installed on the wall of the heating furnace 11 above the discharge port 15. One end of the discharge rod 4 is fixedly connected to the wall of the heating furnace 11. A groove 1221 is formed on the outer surface of the outer cylinder 122, opposite to the discharge rod 4, along the circumference of the outer cylinder 122. The end of the discharge rod 4 away from the wall of the heating furnace 11 extends into the groove 1221. The discharge rod 4 is inclined, with the end connected to the wall of the heating furnace 11 higher than the end extending into the groove 1221. The end of the discharge rod 4 extending into the groove 1221 is horizontally opposite to the discharge port 15.

[0053] Reference Figure 4 , Figure 7 As the unloading platform 124 gradually rotates to the discharge port, the aluminum rod on the unloading platform 124 comes into contact with the unloading push rod 4. Since the position of the unloading push rod 4 is fixed, as the rotating cylinder 12 rotates, the aluminum rod on the unloading platform 124 is gradually pushed towards the discharge port 15 under the action of the unloading push rod 4, so that the aluminum rod enters the discharge port 15.

[0054] Reference Figure 1 , Figure 3 The feeding mechanism 2 includes a feeding channel 21 fixed to the outer surface of the heating furnace body 1, and the feeding channel 21 is inclined. One end of the feeding channel 21 is connected to the feed inlet 14, and the other end of the feeding channel 21 is the inlet of the feeding channel 21. The height of the feeding channel 21 gradually increases from the end connected to the feed inlet 14 to the other end.

[0055] An opening 211 is provided at the top of the end of the feeding channel 21 that connects to the heating furnace body 1. A gate 22 is slidably connected inside the opening 211, and the gate 22 is vertically oriented. A vertically oriented hydraulic cylinder 23 is fixed to the outer surface of the heating furnace body 1, and the piston rod of the hydraulic cylinder 23 is fixedly connected to the gate 22. The gate 22 moves vertically under the action of the hydraulic cylinder 23. When the gate 22 moves downward into the feeding channel 21, it separates the feed inlet 14 from the feeding channel 21, preventing the aluminum rod inside the feeding channel 21 from entering the feed inlet 14. When the gate 22 is lifted by the hydraulic cylinder 23, it is pulled out from the opening 211, at which point the feed inlet 14 and the feeding channel 21 are connected, and the aluminum rod inside the feeding channel 21 can enter the feed inlet 14.

[0056] The discharge mechanism 3 includes a discharge channel 31 connected to the discharge port 15. The discharge channel 31 includes a discharge section 311 connected to the discharge port 15 and a cooling section 312 connected to the end of the discharge section 311 away from the discharge port 15. The discharge section 311 is inclined. The height of the end of the discharge section 311 connected to the discharge port 15 gradually decreases towards the end connected to the cooling section 312.

[0057] Cooling fans 32 are installed at intervals along the length of the cooling section 312 at the top of the interior of the cooling section 312. The cooling fans 32 are used to blow air to cool down the aluminum rods that enter the cooling section 312.

[0058] A method of using an aluminum rod homogenizing heating furnace according to an embodiment of this application: The aluminum rod to be homogenized is placed into the interior of the heating furnace chamber 11 through the feeding channel 21. The aluminum rod entering the heating furnace chamber 11 falls onto the discharge platform 124 of the rotating drum 12. As the rotating drum 12 rotates counterclockwise, the clamping claw 125 clamps and fixes the aluminum rod onto the discharge platform 124. As the rotating drum 12 rotates counterclockwise, the aluminum rod moves inside the heating furnace chamber 11 and eventually moves to the discharge port 15. Finally, the homogenized and heated aluminum rod is discharged into the interior of the discharge channel 31 through the discharge port 15.

[0059] The heating time of the aluminum rod inside the heating furnace 11 is controlled by the rotation speed of the rotating drum 12. If the aluminum rod needs to be heated for a longer time inside the heating furnace 11, the rotation speed of the rotating drum 12 is slowed down; if the aluminum rod needs to be heated for a shorter time inside the heating furnace 11, the rotation speed of the rotating drum 12 is increased.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
