Description

Technical Field

[0001] This utility model relates to the field of mixing furnace technology, and in particular to a multi-chute heating mixing furnace. Background Technology

[0002] In the aluminum processing industry, the mixing furnace is the core equipment for achieving homogenization of molten aluminum. It ensures stable composition and temperature of molten aluminum by stirring, heating, and maintaining different batches and compositions, providing qualified raw materials for subsequent rolling, casting, and other processes. The chute, as a key channel for molten aluminum transport, typically connects the mixing furnace to various production lines in an inclined trough structure. It achieves directional transport of molten aluminum using gravity or external force, and is a crucial component ensuring the coordinated operation of the mixing furnace and production lines.

[0003] The prior art disclosure number "CN203541517U" discloses "a structural configuration of an aluminum liquid chute between a mixing furnace and a casting machine". When the mixing furnace is casting for at least two casting machines simultaneously, it ensures that the distance from the mixing furnace to each casting machine is the same. Therefore, the temperature of the aluminum liquid entering the casting machine can be easily determined and controlled based on the working chute length, thereby ensuring the casting quality of aluminum ingots. The feeding end of each casting machine is connected to the discharging end of the mixing furnace through an additional chute, which makes it more convenient when a casting machine needs to be supplied with aluminum separately, and the working chute length is shorter, making it easier to determine and control the temperature of the aluminum liquid entering the casting machine. However, this system still has the following problems.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: The solution is equipped with a double chute, but the emergency chute itself is not used frequently during operation. This results in it being kept at room temperature. Sudden contact with ultra-high temperature molten aluminum can cause the emergency chute to break. In addition, the chute itself is connected to the mixing furnace by flanges, which makes disassembly and maintenance difficult and prolongs downtime. Utility Model Content

[0005] The technical problem to be solved by this utility model is that most of the emergency chutes in the existing mixing furnaces are prone to breakage when they suddenly come into contact with molten aluminum, and require shutdown for repair when damaged. The disassembly of the chutes is also cumbersome. To address this, we propose a multi-chute heating mixing furnace.

[0006] To achieve the above objectives, this application adopts the following technical solution: a multi-chute heating mixing furnace, comprising a mixing furnace body, a liquid outlet on the side of the mixing furnace body, a main chute attached to the other side of the liquid outlet, an auxiliary block sleeved on the outer side of the main chute, a return spring connected to the side of the auxiliary block, a fixing block connected to the outer side of the main chute, a support frame connected to the side of the fixing block, a hydraulic rod connected to the bottom of the fixing block, an emergency chute provided below the main chute, a buffer block provided below the emergency chute, an inclined block connected inside the buffer block, and air outlets connected to both sides of the buffer block.

[0007] Preferably, there are three main bodies of the mixing furnace. The main body of the mixing furnace is fixedly connected to the liquid outlet and the main body of the mixing furnace is fixedly connected to the gas outlet. The waste gas and molten aluminum are discharged through the cooperation of the gas outlet and the liquid outlet.

[0008] Preferably, the main chute and the outlet have a magnetic attraction structure. A magnet is fixedly connected to the inner side of the main chute and a magnet is fixedly connected to the outer side of the outlet. An electromagnetic valve is also provided on the inner side of the main chute. By cooperating with the main chute and the outlet, the molten aluminum from multiple mixing furnaces is discharged to the top of different production lines.

[0009] Preferably, the main chute and the fixing block are connected by a sliding connection. Support frames are symmetrically distributed on the outer side of the fixing block. The support frames and the main chute are interlocked. The main chute is fixed by the fixing block and the support frames to prevent the main chute from moving during use.

[0010] Preferably, the size and shape of the emergency chute are the same as those of the main chute. The emergency chute is connected to the fixed block by a sliding connection. Hydraulic rods are symmetrically distributed below the fixed block. The hydraulic rods are used to drive the fixed block to rise and fall, so that the emergency chute can replace the main chute. Preferably, the two different hydraulic rods need to be equipped with a frequency coordinator.

[0011] Preferably, the buffer block is attached to the bottom of the emergency chute, and the buffer block has inclined blocks distributed alternately inside. The buffer block has air outlets symmetrically distributed on both sides. By cooperating with the emergency chute, the high-temperature exhaust gas can preheat the emergency chute, avoiding the emergency chute from directly contacting the high-temperature molten aluminum and causing it to break.

[0012] Preferably, the auxiliary block forms a spring reset structure with the mixing furnace body through a reset spring. High-temperature resistant rubber rings are symmetrically distributed on both sides of the auxiliary block. The auxiliary block is connected to the liquid outlet by a sliding connection. The size of the liquid outlet is the same as the size of the main chute. The auxiliary block is used to limit the liquid outlet and the emergency chute to prevent leakage at their connection.

[0013] The technical effects and advantages of this utility model are as follows: In this invention, an emergency chute allows for rapid replacement of the main chute when it is damaged. An emergency chute is installed below the main chute. When the main chute is damaged, an auxiliary block is pushed to expose the outlet. Then, a hydraulic rod drives the emergency chute to rise a fixed distance, precisely aligning the emergency chute with the outlet. A magnet quickly attracts the chute to complete the connection. Afterward, a reset spring drives the auxiliary block to reset and perform a secondary seal at the connection point to prevent leakage. The entire replacement process is tool-free, fast, and precise, significantly reducing downtime.

[0014] In this invention, the waste gas from the main body of the mixing furnace is used for preheating to ensure that the emergency chute can be used directly: by discharging the waste gas from the bottom of the main body of the mixing furnace, the waste gas passes through the bottom of the emergency chute in an S-shape, thereby heating the emergency chute and keeping it at a high temperature, thus preventing the high-temperature molten aluminum from affecting the emergency chute when it is put into direct use.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a technical solution: a multi-chute heating mixing furnace, including a mixing furnace body 1. A liquid outlet 12 is provided on the side of the mixing furnace body 1 for discharging molten aluminum. A main chute 2 is attached to the other side of the liquid outlet 12, through which molten aluminum from multiple mixing furnace bodies 1 is collected and discharged. An auxiliary block 10 is fitted on the outside of the main chute 2 to seal the connection between the main chute 2 and the liquid outlet 12, preventing leakage. A return spring 11 is also connected to the side of the auxiliary block 10, which drives the auxiliary block 10 to return to its original position, preventing movement. A fixing block 4 is connected to the outside of the main chute 2. The main chute 2 and the emergency chute 3 are fixed to prevent them from falling off. A support frame 5 is connected to the side of the fixing block 4. The support frame 5 is used to assist in fixing and ensure the stability of the main chute 2. A hydraulic rod 7 is connected to the bottom of the fixing block 4. The hydraulic rod 7 is used to drive the emergency chute 3 to rise to a fixed height, thereby quickly aligning it. An emergency chute 3 is set below the main chute 2. The emergency chute 3 is used to continue production when the main chute 2 is damaged. A buffer block 6 is set below the emergency chute 3. The buffer block 6 is used to buffer the exhaust gas and extend the exhaust gas residence time. An inclined block 8 is also connected inside the buffer block 6. The inclined block 8 is used to further extend the exhaust gas residence time. An exhaust port 9 is connected to both sides of the buffer block 6.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in this embodiment: there are three mixing furnace bodies 1. The mixing furnace body 1 is fixedly connected to the liquid outlet 12. The mixing furnace body 1 is also fixedly connected to the gas outlet 9. By cooperating with the liquid outlet 12, the waste gas and molten aluminum are discharged. The main chute 2 and the liquid outlet 12 have a magnetic adsorption structure. A magnet is fixedly connected to the inner side of the main chute 2 and a magnet is fixedly connected to the outer side of the liquid outlet 12. A solenoid valve is also installed on the inner side of the main chute 2. By cooperating with the liquid outlet 12, the molten aluminum from multiple mixing furnaces is discharged to the top of different production lines. The main chute 2 is slidably connected to the fixing block 4. Support frames 5 are symmetrically distributed on the outer side of the fixing block 4. The support frames 5 and the main chute 2 have an interlocking structure. The main chute 2 is fixed by the fixing block 4 and the support frames 5 to prevent the main chute 2 from moving during use.

[0020] Reference Figure 1 , Figure 2 and Figure 3As shown in this embodiment: the size and shape of the emergency chute 3 are the same as those of the main chute 2. The emergency chute 3 is connected to the fixed block 4 by a sliding connection. Hydraulic rods 7 are symmetrically distributed below the fixed block 4. The hydraulic rods 7 are used to drive the fixed block 4 to rise and fall, so that the emergency chute 3 can replace the main chute 2 for use. Preferably, the two different hydraulic rods 7 need to be equipped with a frequency coordinator.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this embodiment: the buffer block 6 is attached to the bottom of the emergency chute 3. Inclined blocks 8 are staggered inside the buffer block 6. Air outlets 9 are symmetrically distributed on both sides of the buffer block 6. By cooperating with the emergency chute 3, the high-temperature exhaust gas can preheat the emergency chute 3, preventing the emergency chute 3 from directly contacting the high-temperature molten aluminum and causing it to break. The auxiliary block 10 forms a spring reset structure with the mixing furnace body 1 through the reset spring 11. High-temperature resistant rubber rings are symmetrically distributed on both sides of the auxiliary block 10. The auxiliary block 10 is connected to the liquid outlet 12 by a sliding connection. The size of the liquid outlet 12 is the same as the size of the main chute 2. The auxiliary block 10 is used to limit the liquid outlet 12 and the emergency chute 3 to prevent leakage at their connection.

[0022] Working principle: First, during the use of the mixing furnace body 1, molten aluminum is discharged into the main chute 2 through the outlet 12. Then, the main chute 2 discharges the molten aluminum to different production lines. At this time, the exhaust gas of the mixing furnace body 1 enters the outlet 9 through the tail gas port and is discharged. The exhaust gas will pass through the buffer block 6 and then through multiple inclined blocks 8, which prolongs the residence time of the exhaust gas inside the buffer block 6. The heat itself will flow upward, and the buffer block 6 is attached to the bottom of the emergency chute 3, which will heat the emergency chute 3. Similarly, assuming the main chute 2 is damaged, the auxiliary block 10 is pushed by the tool rod as an extension, causing it to detach from the main chute 2 and approach the outlet 12. Then, the switch of the hydraulic rod 7 is turned on. Under the action of the frequency synchronizer, the hydraulic rods 7 on both sides drive the fixing block 4 to rise to a fixed height. When the fixing block 4 rises, it will drive the emergency chute 3 to rise. At the same time, the support frame 5 helps to fix the emergency chute 3, ensuring that it is stable and does not shake when rising. Due to the control of the hydraulic rod 7, the emergency chute 3 will rise to a fixed height, that is, the height aligned with the outlet 12. At this time, the magnet on the inside of the emergency chute 3 is aligned with the outlet 12. The magnets on the outside attract each other and are initially fixed. The auxiliary block 10 is released and reset under the action of the reset spring 11. The center of the auxiliary block 10 coincides with the connection between the liquid outlet 12 and the emergency chute 3, and a second limit is set to achieve the purpose of preventing liquid leakage. The main body of the mixing furnace 1 can then be restarted. The molten aluminum is discharged into the interior of the emergency chute 3 through the liquid outlet 12 and then dispersed to different production lines above through the emergency chute 3. The support frame 5 is fixed to the fixing block 4 with threaded nails. The threaded nails are removed to release the fixation of the support frame 5. The support frame 5 drives the main chute 2 to slide out of the fixing block 4 for maintenance.

[0023] It is important to note that the other side of the main chute 2 and the emergency chute 3 should have a tree-like branching structure according to the number of production lines. For example, if there are four production lines, four branch chutes should be drawn. Since this is existing technology, it is not shown in the figure.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
