Description

Technical Field

[0001] This application relates to the field of metallurgical technology, and in particular to an aluminum ingot smelting system for hydrogen energy endplate production. Background Technology

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode, respectively. Hydrogen diffuses outward through the anode and reacts with the electrolyte, releasing electrons that travel through an external load to the cathode. The hydrogen energy endplate is a crucial component of the hydrogen fuel cell, and aluminum melting is the first step in its production process. Generally, high-purity aluminum ingots or aluminum scraps and shavings generated during the cutting of the hydrogen energy endplate are used as raw materials.

[0003] The aforementioned technologies have the following drawbacks: DE waste gas is generated during the smelting process of aluminum ingots, and direct discharge can easily cause environmental pollution. Summary of the Invention

[0004] In order to effectively reduce air pollution during the aluminum ingot smelting process, this application provides an aluminum ingot smelting system for hydrogen energy end plate production.

[0005] The purpose of this application is to provide an aluminum ingot smelting system for hydrogen energy endplate production, which adopts the following technical solution:

[0006] A hydrogen energy endplate production aluminum ingot smelting system includes a smelting furnace, a waste gas collection hood, and a waste gas treatment chamber. The waste gas collection hood is located above the inlet of the smelting furnace. The waste gas treatment chamber includes an inlet and an outlet. The inlet is located upstream of the gas flow in the waste gas treatment chamber, and the outlet is located downstream of the gas flow in the waste gas treatment chamber. A waste gas pipe connects the waste gas collection hood and the inlet of the waste gas treatment chamber. A sludge discharge port is provided at the bottom of the waste gas treatment chamber. A filter assembly for dividing the gas flow into upper and lower parts is installed inside the waste gas treatment chamber, and the filter assembly is located between the inlet and the outlet.

[0007] By adopting the above technical solution, during the calcination of aluminum ingots in the smelting furnace, impurities in the aluminum ingots form flue gas along with the calcination. The flue gas is introduced into the flue gas treatment chamber using a waste gas collection hood and waste gas pipeline. During the flow of the flue gas in the flue gas treatment chamber, the impurities in the flue gas will be blocked by the filter components in the lower half of the flue gas treatment chamber, making it easy to remove and centrally process them through the impurity discharge port. The filtered flue gas will be discharged from the exhaust port, thereby reducing air pollution during the aluminum ingot smelting process.

[0008] Optionally, the filter assembly includes a mounting frame and a filter screen, and the exhaust gas treatment chamber is provided with a cleaning component for abutting against the lower surface of the filter screen, and the exhaust gas treatment chamber is provided with a drive mechanism for driving the cleaning component to move along the length direction of the filter screen.

[0009] By adopting the above technical solution, the driving mechanism drives the cleaning component to move on the filter screen, which facilitates the removal of impurities adhering to the filter screen and causes the impurities to fall to the bottom of the exhaust gas treatment chamber, thereby improving the filtration effect of the filter screen on the flue gas.

[0010] Optionally, the driving mechanism includes a cleaning screw, the two ends of which are rotatably connected to the side wall of the exhaust gas treatment chamber; a cleaning guide rod parallel to the cleaning screw is disposed inside the exhaust gas treatment chamber, the cleaning screw and the cleaning guide rod being located on opposite inner side walls of the exhaust gas treatment chamber; one end of the cleaning component is threadedly connected to the cleaning screw, and the other end of the cleaning component is slidably connected to the cleaning guide rod; a power assembly for driving the cleaning screw to rotate is disposed on the exhaust gas treatment chamber.

[0011] By adopting the above technical solution, the cleaning guide rod can guide the movement of the cleaning component, and then the power component drives the cleaning screw to rotate, so that the cleaning component moves on the filter screen, thereby achieving the purpose of cleaning impurities on the filter screen.

[0012] Optionally, the power assembly includes a transmission rod, the two ends of which are rotatably connected to the side wall of the exhaust gas treatment chamber. A power component for driving the transmission rod to rotate is provided outside the exhaust gas treatment chamber. A first bevel gear is fixedly connected to the transmission rod, and a cleaning bevel gear that meshes with the first bevel gear is fixedly connected to the cleaning screw.

[0013] By adopting the above technical solution, the transmission rod is rotated by the power component, which in turn drives the first bevel gear to rotate together. Since the first bevel gear meshes with the cleaning bevel gear, it will drive the cleaning bevel gear to rotate together, thus making it easier for the cleaning screw in the exhaust gas treatment chamber to rotate.

[0014] Optionally, the bottom of the exhaust gas treatment chamber is provided with an ejection block for ejecting impurities from the discharge port. The exhaust gas treatment chamber is provided with an ejection screw and an ejection guide rod, which are parallel to each other and located on opposite sides of the ejection block. One end of the ejection block is threaded to the ejection screw, and the other end of the ejection block is slidably connected to the ejection guide rod. The transmission rod is provided with a transmission assembly for driving the ejection screw to rotate.

[0015] By adopting the above technical solution, the guide rod can guide the movement of the ejector block, and then the transmission component drives the ejector screw to rotate, so that the ejector block moves at the bottom of the exhaust gas treatment chamber, which facilitates the ejection of impurities in the exhaust gas treatment chamber from the discharge port.

[0016] Optionally, the transmission assembly includes a second bevel gear and an ejection bevel gear, the second bevel gear being fixedly connected to the transmission rod, and the ejection bevel gear being fixedly connected to the ejection screw; the power component includes a drive motor, a guide sleeve being fixedly connected to the output shaft of the drive motor, and a guide block being fixedly connected to one end of the transmission rod facing the drive motor, the guide block being inserted into and slidably connected within the guide sleeve; a shifting assembly is provided in the exhaust gas treatment chamber, the shifting assembly being used to drive the guide block to move within the guide sleeve so that the first bevel gear meshes with the cleaning bevel gear or the second bevel gear meshes with the ejection bevel gear.

[0017] By adopting the above technical solution, when it is necessary to discharge impurities from the exhaust gas treatment chamber, the shifting component makes the second bevel gear mesh with the ejection bevel gear, and the drive motor is started to make the transmission rod rotate, which will drive the second bevel gear to rotate together. Since the second bevel gear meshes with the ejection bevel gear, it will drive the ejection bevel gear to rotate together, thus making it easier for the ejection screw in the exhaust gas treatment chamber to rotate.

[0018] Optionally, the side wall of the exhaust gas treatment chamber is hinged with a discharge door for covering the discharge port; the shifting assembly includes a shift lever and a shift ring, the shift ring being fixedly connected to the transmission rod; the inner wall of the exhaust gas treatment chamber has a shifting hole for the shift lever to slide, the shifting hole communicating with the discharge port; one end of the shift lever abuts against the lower surface of the shift ring, and the other end of the shift lever abuts against the upper surface of the discharge door; a shifting spring is provided inside the guide sleeve, one end of the shifting spring being fixedly connected to the guide sleeve, and the other end of the shifting spring being fixedly connected to the guide block.

[0019] By adopting the above technical solution, when the discharge door is closed, it will move upward against the shift lever, causing the transmission rod and shift ring to move upward. This facilitates the engagement of the first bevel gear with the cleaning bevel gear, while the second bevel gear disengages from the push-out bevel gear. The drive motor then rotates the cleaning screw to facilitate cleaning impurities from the filter screen. When the discharge door is open, the shift spring pushes the guide block downward, causing the transmission rod to move downward. This facilitates the engagement of the second bevel gear with the push-out bevel gear, while the first bevel gear disengages from the cleaning bevel gear. The drive motor then rotates the push-out screw to facilitate pushing out impurities from the exhaust gas treatment chamber.

[0020] Optionally, the shift lever is rotatably connected to a pulley at one end facing the shift ring, and the circumferential surface of the pulley abuts against the lower surface of the shift ring.

[0021] By adopting the above technical solution, when the transmission rod rotates under the action of the power component, the pulley will roll on the surface of the shift ring, thereby reducing the resistance encountered by the transmission rod when it rotates.

[0022] Optionally, a handle is fixedly connected to the side of the waste discharge door.

[0023] By adopting the above technical solution, the handle makes it easier to open the waste disposal door.

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

[0025] 1. During the calcination of aluminum ingots in the smelting furnace, impurities in the aluminum ingots are converted into flue gas during calcination. The flue gas is introduced into the flue gas treatment chamber using a waste gas collection hood and waste gas pipeline. As the flue gas circulates in the flue gas treatment chamber, the impurities in the flue gas are blocked by the filter components in the lower half of the flue gas treatment chamber, making it easy to remove and centrally process them through the impurity discharge port. The filtered flue gas will be discharged from the exhaust port, thereby reducing air pollution during the aluminum ingot smelting process.

[0026] 2. When the exhaust door is closed, it moves upward against the shift lever, causing the transmission rod and shift ring to move upward. This facilitates the engagement of the first bevel gear with the cleaning bevel gear, while the second bevel gear disengages from the push-out bevel gear. The drive motor then rotates the cleaning screw to clean impurities from the filter screen. When the exhaust door is open, the shift spring pushes the guide block downward, causing the transmission rod to move downward. This facilitates the engagement of the second bevel gear with the push-out bevel gear, while the first bevel gear disengages from the cleaning bevel gear. The drive motor then rotates the push-out screw to push impurities out of the exhaust gas treatment chamber. Attached Figure Description

[0033] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-5 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0034] This application discloses an aluminum ingot smelting system for hydrogen energy endplate production. (Refer to...) Figure 1 The aluminum ingot smelting system includes a base 27 and a smelting furnace 1. A furnace cover 21 is rotatably connected to the base 27, and an on / off motor 22 is bolted to the base 27. The output shaft of the on / off motor 22 is fixed to the rotation shaft of the furnace cover 21 by a key connection. By covering the feed inlet of the smelting furnace 1 with the furnace cover 21, the overflow of molten aluminum during the smelting process can be reduced. Activating the on / off motor 22 causes the furnace cover 21 to rotate on the base 27, facilitating the addition of aluminum ingots into the smelting furnace 1 through the feed inlet.

[0035] Reference Figure 1 To ensure the aluminum ingots are fully smelted within the smelting furnace 1, the aluminum ingot smelting system also includes an oxygen pipe 23, which is fixed to the ceiling of the production workshop using a round rod. A flue gas vent 24 is provided on the furnace cover 21, located on the side of the furnace cover 21 away from the base 27; and the flue gas vent 24 allows one end of the oxygen pipe 23 to be inserted into the smelting furnace 1. A large amount of flue gas is generated during the aluminum ingot smelting process; the flue gas is discharged through the flue gas vent 24 to facilitate better smelting of the aluminum ingots.

[0036] Reference Figure 1The aluminum ingot smelting system also includes a waste gas collection hood 2 and a waste gas treatment chamber 3. The waste gas collection hood 2 is fixed to the ceiling of the production workshop by a hanging rod 26.

The waste gas treatment chamber 3 includes an air inlet 31 and an exhaust outlet 32. The air inlet 31 is located upstream of the gas flow in the waste gas treatment chamber 3, and the exhaust outlet 32 ​​is located downstream of the gas flow in the waste gas treatment chamber 3. In this embodiment, the air inlet 31 is located in the middle of the waste gas treatment chamber 3, and the exhaust outlet 32 ​​is located at the top of the waste gas treatment chamber 3.

[0037] Reference Figure 1 An exhaust gas pipe 4 is installed between the exhaust gas collection hood 2 and the exhaust gas treatment chamber 3. One end of the exhaust gas pipe 4 is connected to the exhaust gas collection hood 2, and the other end of the exhaust gas pipe 4 passes through the air inlet 31 and is located inside the exhaust gas treatment chamber 3. A sludge discharge port 5 is provided at the bottom of the exhaust gas treatment chamber 3, and a sludge discharge door 17 is hinged to the sludge discharge port 5. The sludge discharge door 17 can cover the sludge discharge port 5 to reduce the leakage of exhaust gas from the sludge discharge port 5. In other embodiments, a sealing ring is fixed to the side of the sludge discharge door 17 with glue to reduce the leakage of exhaust gas from the gap between the sludge discharge port 5 and the sludge discharge door 17.

[0038] Reference Figure 1 To make it easier to open the waste disposal door 17, a handle 25 is welded to the side of the waste disposal door 17. The handle 25 is in the shape of an inverted U. The handle 25 makes it easier to open the waste disposal door 17.

[0039] Reference Figure 2 and Figure 3 A filter assembly 6 is installed inside the exhaust gas treatment chamber 3. The filter assembly 6 divides the gas flow into upper and lower parts and is located between the air inlet 31 and the exhaust outlet 32. The filter assembly 6 includes a mounting frame 61 and a filter screen 62. The outer wall of the mounting frame 61 is fixedly connected to the four inner walls of the exhaust gas treatment chamber 3 with screws. The filter screen 62 is detachably connected to the inner wall of the mounting frame 61. The filter screen 62 filters impurities in the flue gas, which helps to reduce the pollution of the air by the emitted flue gas.

[0040] Reference Figure 2 and Figure 4 A cleaning component 7 is installed inside the exhaust gas treatment chamber 3. In this embodiment, the cleaning component 7 is a brush, with the brush bristles abutting against the upper and lower surfaces of the filter screen 62. A driving mechanism is installed inside the exhaust gas treatment chamber 3. The driving mechanism drives the cleaning component 7 to move along the length of the filter screen 62, facilitating the removal of impurities adhering to the filter screen 62 and causing the impurities to fall to the bottom of the exhaust gas treatment chamber 3, thereby improving the filtration effect of the filter screen 62.

[0041] Reference Figure 2 and Figure 4 The driving mechanism includes a cleaning lead screw 81 and a cleaning guide rod 82. The two ends of the cleaning lead screw 81 are rotatably connected to the side wall of the exhaust gas treatment chamber 3. The two ends of the cleaning guide rod 82 are fixedly connected to the side wall of the exhaust gas treatment chamber 3. The cleaning guide rod 82 is parallel to the cleaning lead screw 81, and the cleaning lead screw 81 and the cleaning guide rod 82 are located on opposite inner side walls of the exhaust gas treatment chamber 3, respectively. One end of the cleaning component 7 is threadedly connected to the cleaning lead screw 81, and the other end of the cleaning component 7 is slidably connected to the cleaning guide rod 82. It should be noted that the cleaning guide rod 82 guides the movement of the cleaning component 7; the rotation of the cleaning lead screw 81 causes the cleaning component 7 to move on the filter screen 62, achieving the purpose of cleaning impurities on the filter screen 62.

[0042] Reference Figure 2 and Figure 4 A power assembly 9 is installed on the exhaust gas treatment chamber 3. The power assembly 9 includes a transmission rod 91, a power component 92, a first bevel gear 93, and a cleaning bevel gear 94. The two ends of the transmission rod 91 are rotatably connected to the side wall of the exhaust gas treatment chamber 3. The power component 92 is a drive motor, which is fixed to the top of the exhaust gas treatment chamber 3 and drives the transmission rod 91 to rotate. The first bevel gear 93 is fixed to the transmission rod 91 by a key connection, and the cleaning bevel gear 94 is fixed to the cleaning screw 81 by a key connection, and the cleaning bevel gear 94 meshes with the first bevel gear 93. Starting the drive motor causes the transmission rod 91 to rotate, which in turn drives the first bevel gear 93 to rotate. Since the first bevel gear 93 meshes with the cleaning bevel gear 94, it drives the cleaning bevel gear 94 to rotate as well, thus making it easier for the cleaning screw 81 inside the exhaust gas treatment chamber 3 to rotate.

[0043] Reference Figure 4 and Figure 5 The bottom of the exhaust gas treatment chamber 3 is equipped with an ejector block 10, an ejector screw 11, and an ejector guide rod 12. The ejector block 10 is slidably connected to the bottom wall of the exhaust gas treatment chamber 3. The two ends of the ejector screw 11 are rotatably connected to the side wall of the exhaust gas treatment chamber 3. The two ends of the ejector guide rod 12 are fixedly connected to the side wall of the exhaust gas treatment chamber 3. The ejector screw 11 and the ejector guide rod 12 are parallel, and the ejector screw 11 and the ejector guide rod 12 are located on opposite inner side walls of the exhaust gas treatment chamber 3, respectively. That is, the ejector screw 11 and the ejector guide rod 12 are located on both sides of the ejector block 10. One end of the ejector block 10 is threaded to the ejector screw 11, and the other end of the ejector block 10 is slidably connected to the ejector guide rod 12. The guide rod 12 guides the movement of the push block 10, and the push screw 11 rotates to move the push block 10 on the bottom wall of the exhaust gas treatment chamber 3, which facilitates the pushing of impurities in the exhaust gas treatment chamber 3 out of the discharge port 5.

[0044] Reference Figure 4 and Figure 5 A transmission assembly 13 is installed on the transmission rod 91. The transmission assembly 13 includes a second bevel gear 131 and an ejection bevel gear 132. The second bevel gear 131 is fixedly connected to the transmission rod 91 by a key connection, and the ejection bevel gear 132 is fixedly connected to the ejection screw 11 by a key connection. A guide sleeve 14 is fixedly connected to the output shaft of the drive motor. A guide block 15 is fixedly connected to the end of the transmission rod 91 facing the drive motor. The guide block 15 is inserted into and slidably connected inside the guide sleeve 14.

[0045] Reference Figure 4 and Figure 5 A shifting assembly 16 is installed inside the exhaust gas treatment chamber 3. The shifting assembly 16 is used to drive the guide block 15 to move within the guide sleeve 14 so that the first bevel gear 93 meshes with the cleaning bevel gear 94 or the second bevel gear 131 meshes with the ejection bevel gear 132. In this embodiment, when it is necessary to discharge impurities from the exhaust gas treatment chamber 3, the shifting assembly 16 causes the second bevel gear 131 to mesh with the ejection bevel gear 132, and the drive motor is started to rotate the transmission rod 91, which will drive the second bevel gear 131 to rotate together. Since the second bevel gear 131 meshes with the ejection bevel gear 132, it will drive the ejection bevel gear 132 to rotate together, thereby making it easier for the ejection screw 11 in the exhaust gas treatment chamber 3 to rotate.

[0046] Reference Figure 4 and Figure 5 The shift assembly 16 includes a shift lever 161 and a shift ring 162. The shift ring 162 is fixedly connected to the transmission rod 91 by welding. The inner wall of the exhaust gas treatment chamber 3 is provided with a shift hole 18 for the shift lever 161 to slide. The shift hole 18 is connected to the discharge port 5. One end of the shift lever 161 abuts against the lower surface of the shift ring 162, and the other end of the shift lever 161 abuts against the upper surface of the discharge door 17. In this embodiment, when the discharge door 17 is closed, the discharge door 17 will move upward against the shift lever 161, thereby causing the transmission rod 91 and the shift ring 162 to move upward, so that the first bevel gear 93 can mesh with the cleaning bevel gear 94, while the second bevel gear 131 can separate from the push-out bevel gear 132. In this way, the drive motor will drive the cleaning screw 81 to rotate, so as to facilitate the cleaning of impurities on the filter screen 62.

[0047] Reference Figure 4 and Figure 5A shift spring 19 is installed inside the guide sleeve 14. One end of the shift spring 19 is fixedly connected to the guide sleeve 14, and the other end is fixedly connected to the guide block 15. In this embodiment, when the discharge door 17 is opened, the shift spring 19 will push the guide block 15 downward, thereby causing the transmission rod 91 to move downward, so that the second bevel gear 131 can mesh with the push-out bevel gear 132, while the first bevel gear 93 can separate from the cleaning bevel gear 94. This drives the motor to rotate the push-out screw 11, so as to push out the impurities in the exhaust gas treatment chamber 3.

[0048] Reference Figure 2 and Figure 5 A pulley 20 is rotatably connected to one end of the shift lever 161 facing the shift ring 162, and the circumferential surface of the pulley 20 abuts against the lower surface of the shift ring 162. When the transmission rod 91 rotates under the action of the power component 92, the pulley 20 will roll on the surface of the shift ring 162, thereby reducing the resistance encountered by the transmission rod 91 when rotating.

[0049] The implementation principle of the aluminum ingot smelting system for hydrogen energy endplate production in this application embodiment is as follows: During the calcination process of the aluminum ingot in the smelting furnace 1, impurities in the aluminum ingot form flue gas along with the calcination. The flue gas is introduced into the flue gas treatment chamber 3 using the waste gas collection hood 2 and the waste gas pipe 4. During the flow of the flue gas in the flue gas treatment chamber 3, the impurities in the flue gas are blocked by the filter assembly 6 in the lower half of the flue gas treatment chamber 3, and some impurities adhere to the filter screen 62. The motor drives the cleaning screw 81 to rotate, so as to facilitate the cleaning of impurities on the filter screen 62. When the second bevel gear 131 meshes with the ejection bevel gear 132, the motor drives the ejection screw 11 to rotate, so as to facilitate the pushing out of the impurities in the flue gas treatment chamber 3.
