Description

Technical Field

[0001] This application relates to the technical field of aluminum granule feeding, and in particular to an aluminum granule feeding system. Background Technology

[0002] In the process of producing titanium dioxide using the chloride process, aluminum trichloride is added to the oxidation stage to improve the rutile crystal form conversion rate of the titanium dioxide semi-finished product. Aluminum trichloride is produced by reacting aluminum granules with chlorine gas at high temperatures; typically, aluminum granules are added as a raw material to a reactor containing chlorine gas for the reaction.

[0003] Before adding aluminum granules to the reactor, the storage tank containing the granules needs to be pressurized to ensure that the pressure inside the tank is greater than the pressure inside the reactor. This allows the aluminum granules to be transported from the tank to the reactor under pressure. A weighing device is installed inside the tank to weigh the entire tank and calculate the weight of the aluminum granules. However, after the tank is pressurized, the air pressure inside interferes with the weighing device, resulting in poor accuracy in the measurement of aluminum granules and severely impacting the manufacturing process. Utility Model Content

[0004] To address the aforementioned technical problems in the prior art, this application provides an aluminum granule feeding system that can weigh materials to a preset weight using a weighing tank, thereby achieving precise dosage feeding. Furthermore, the weighing tank and the blowing tank are set up separately, which can effectively avoid interference from the pressure of the blowing tank during the blowing process with the detection results of the weighing device, effectively ensuring the accuracy of the weighing results of the weighing device set on the weighing tank, and thus improving the reliability of the aluminum granule feeding system.

[0005] This application provides an aluminum granule feeding system, which includes a feeder, a weighing tank, a blown powder tank, and a control device. The feeder's inlet is connected to a hopper, and the feeder is used to convey material from the hopper. The weighing tank's upper inlet is connected to the feeder's outlet. The weighing tank includes a tank body and a weighing device mounted on the tank body, which is used to detect the weight information of the tank body. The blown powder tank's upper inlet is connected to the weighing tank's lower outlet, and the lower outlet of the blown powder tank is used to convey material downstream through a feeding pipe. The blown powder tank is used to hold material that meets a preset weight as measured by the weighing device, and a pressure valve connected to the blown powder tank and communicating with its interior is attached to the blown powder tank. The control device is electrically connected to the weighing device and the pressure valve, respectively. The control device is used to receive the weight information of the material meeting the preset weight detected by the weighing device, and after the blown powder tank holds the material meeting the preset weight, it sends a control command to the pressure valve to open it.

[0006] In some embodiments, a first outlet valve is provided at the outlet of the spray can. When the first outlet valve is in the open state, there is a preset gap between the valve core and the valve body. The preset gap is used to block the material.

[0007] In some embodiments, the valve core of the first outlet valve is configured to be eccentrically hemispherical.

[0008] In some embodiments, the aluminum granule feeding system further includes a protective pipe and a generator connected to both ends of the feeding pipe, respectively, wherein the protective pipe is used to supply protective gas flowing into the generator to the feeding pipe.

[0009] In some embodiments, the feeding pipe is further provided with a second outlet valve and a first inlet valve located downstream of the first outlet valve, and the connection between the feeding pipe and the protection pipe is located between the second outlet valve and the first inlet valve.

[0010] In some embodiments, the control device is electrically connected to the first outlet valve, the second outlet valve, and the first inlet valve, respectively. The control device is also used to control the first inlet valve to be in a normally open state, and to sequentially control the second outlet valve and the first outlet valve to open before the blowing tank conveys material to the generator through the feeding pipe.

[0011] In some embodiments, the blow-off tank is further connected to an exhaust valve communicating with its interior, the control device is electrically connected to the exhaust valve, and the control device is further configured to send a control command to the exhaust valve to open it before the weighing tank discharges material into the blow-off tank.

[0012] In some embodiments, the upper inlet of the spray tank is connected to the lower outlet of the weighing tank via a discharge pipe. The discharge pipe is sequentially equipped with a third outlet valve, a second inlet valve, and a third inlet valve. The third outlet valve is located upstream of the second inlet valve and the third inlet valve. The control device is electrically connected to the third outlet valve, the second inlet valve, and the third inlet valve, respectively. The control device is also used to control the third outlet valve and the third inlet valve to open before the weighing tank discharges material into the spray tank, and then control the second inlet valve to open, so that the material in the weighing tank can enter the spray tank via the discharge pipe.

[0013] In some embodiments, the first inlet valve is configured as a high-temperature valve.

[0014] In some embodiments, the aluminum granule feeding system further includes a feeding funnel, the upper opening of which corresponds to the discharge port of the feeder, and the lower opening of which corresponds to the upper inlet of the weighing tank, so that the discharge port of the feeder supplies material to the upper inlet of the weighing tank through the feeding funnel.

[0015] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: The material conveyed by the feeder can be weighed to a preset weight in the weighing tank, and then supplied to the blowing tank, thereby achieving precise dosage feeding of aluminum granules downstream. This enables quantitative feeding of aluminum granules. Furthermore, the separate setup of the weighing tank and the blowing tank effectively avoids interference from pressure on the weighing device's detection results during the blowing process, effectively ensuring the accuracy of the weighing results from the weighing device on the weighing tank, and thus improving the reliability of the aluminum granule feeding system. Moreover, after the weighing valve is opened, the material can be quickly transported downstream by high-pressure gas transport through the high-pressure gas inside the blowing tank, simplifying the mechanical connection structure between the blowing tank and downstream equipment, such as the mechanical connection structure between the blowing tank and the generator, effectively reducing the probability of failure and the frequency of maintenance in the aluminum granule feeding system.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] This application provides an aluminum granule feeding system. For example... Figure 1As shown, the aluminum granule feeding system includes a feeder 1, a weighing tank 2, a blown powder tank 3, and a control device. The feeder 1 has its inlet connected to a hopper 4, and the feeder 1 is used to transport materials from the hopper 4. The weighing tank 2 has its upper inlet connected to the outlet of the feeder 1. The weighing tank 2 includes a tank body 21 and a weighing device 22 mounted on the tank body 21. The weighing device 22 is used to detect the weight information of the tank body 21. The blown powder tank 3 has its upper inlet connected to the lower outlet of the weighing tank 2, and the lower outlet of the blown powder tank 3 is used to transport materials downstream through a feeding pipe 5. The blown powder tank 3 is used to receive materials weighed by the weighing device 22 that meet a preset weight, and a pressure valve 31 connected to the blown powder tank 3 communicates with its interior. The control device is electrically connected to the weighing device 22 and the pressure valve 31 respectively. The control device is used to receive the weight information of the material that meets the preset weight detected by the weighing device 22, and after the material that meets the preset weight is filled in the blowing tank 3, it sends a control command to the pressure valve 31 to open it.

[0027] The aforementioned feeder 1 is used to supply aluminum granules, which can be understood as aluminum metal particles. Furthermore, the feeder 1 has no rotating parts, making it suitable for feeding granular materials and preventing the aluminum granules from getting stuck or spilling within the feeder 1. For example, current screw feeders and belt feeders are prone to causing granular material to get stuck or spill.

[0028] The feeder 1 described above can adjust the feeding rate, so that aluminum particles can be conveyed downstream of the feeder 1 at a certain rate. Furthermore, different feeding speeds can be achieved by adjusting the feeding rate of the feeder 1 to ensure weighing accuracy.

[0029] The aforementioned hopper 4 can be positioned above the feeder 1. Aluminum particles in the hopper 4 can fall into the feeder 1 under gravity. A first isolation valve 10 and a flexible connector 11 can be sequentially installed between the hopper 4 and the feeder 1. Users can control the material falling from the hopper 4 to the feeder 1 by opening or closing the first isolation valve 10. Furthermore, the opening degree of the first isolation valve 10 can be controlled to regulate the quantity or speed of material falling from the hopper 4 to the feeder 1, thus meeting different usage requirements. The first isolation valve 10 can be electrically connected to a control device, which can electrically open or close the first isolation valve 10. The flexible connector 11 prevents the vibration generated during the operation of the feeder 1 from being transmitted to the hopper 4, effectively ensuring the robustness and reliability of the connection between the hopper 4 and the feeder 1.

[0030] The first isolation valve 10 can preferably be a slide gate valve, or other valves that can be electrically connected to the control device. This application does not specifically limit the type of valve.

[0031] A second isolation valve 12 can be installed between the feeder 1 and the weighing tank 2. By opening or closing the isolation valve, the frequency of material entering the weighing tank 2 can be effectively controlled. Another flexible connector 11 can be installed between the feeder 1 and the second isolation valve 12. This flexible connector 11 can prevent the vibration generated by the feeder 1 during operation from interfering with the weighing tank 2.

[0032] Feeder 1 can be installed upstream of weighing tank 2, and feeder 1 can evenly convey materials into weighing tank 2 through vibration. Feeder 1 can be electrically connected to a control device. By providing different voltages to feeder 1, the control device can make feeder 1 vibrate at different frequencies, thereby controlling the weight of materials conveyed into weighing tank 2 according to actual usage requirements. This achieves precise control of the weight of materials entering weighing tank 2 and prevents excessive accumulation of materials at the second isolation valve 12, effectively ensuring the service life of the second isolation valve 12. In addition, by using feeder 1 with different vibration frequencies, materials can be conveyed to weighing tank 2 in batches, effectively improving the flexibility of feeder 1 in use.

[0033] An automatic valve can be installed at the outlet of the weighing tank 2 to control the discharge of material from the weighing tank 2.

[0034] The weighing range of the weighing tank 2 is adjustable.

[0035] The aforementioned weighing device 22 can support the tank 21 to weigh the weight of the tank 2. When material is transported into the tank 21, the weighing device 22 can accurately measure the weight change of the tank 2, thereby determining the weight of the material.

[0036] The aforementioned weighing device 22 may include a shear beam weighing module to accurately weigh the material in the tank 21, thereby improving the feeding accuracy of the aluminum granule feeding system.

[0037] The aforementioned spray tank 3 can be used to store materials that meet a preset weight after being weighed by the weighing tank 2. A pressurizing valve 31 can be connected to the spray tank 3 via a pressurizing air path, which can be connected to a gas storage tank to provide high-pressure gas into the spray tank 3, thereby increasing the air pressure inside the spray tank 3. A gas storage tank can be connected to the pressurizing air path to supply gas to the pressurizing air path, or a pump can be connected to pressurize and transport the gas from the gas storage tank to the spray tank 3 via the pressurizing air path. A level switch can be installed on the spray tank 3, or a feeding time can be set via a control device to ensure that all material in the spray tank 3 is discharged. This application does not specifically limit the method for determining whether all material in the spray tank 3 has been discharged.

[0038] A pressure detection element can be installed on the above-mentioned injection tank 3, which can detect the pressure inside the injection tank 3 in real time.

[0039] Material detection elements can be installed on the aforementioned blow-up can 3. The material detection elements can detect the material position information inside the blow-up can 3 in real time, specifically the material height information.

[0040] A weight detection element can be installed on the above-mentioned blow-up tank 3, which can detect the weight information of the material in the blow-up tank 3 in real time.

[0041] An automatic valve can be installed at the outlet of the aforementioned spray tank 3 to control the discharge of material from the weighing tank 2.

[0042] The bottom of the weighing tank 2 body 21 and the spray tank 3 can have an inclined surface. When the material enters the weighing tank 2 or the spray tank 3, it can fall along the inclined surface and quickly accumulate at the bottom of the weighing tank 2 or the spray tank 3.

[0043] When the control device receives information that the weight of the material in the injection tank 3 meets the preset requirements, it can control the pressurization valve 31 to open, thereby blowing gas into the injection tank 3 for pressurization. Once the pressure inside the injection tank 3 reaches the preset pressure, the material is rapidly transported downstream under the gas pressure, thus completing one batch of feeding. It is understood that a generator 6 can be installed downstream of the injection tank 3. After pressurization, the pressure inside the injection tank 3 is greater than the pressure inside the generator 6, allowing the material to be transported from the injection tank 3 to the generator 6 under pressure. The gas blown into the injection tank 3 can be a gas that does not readily undergo chemical reactions, such as nitrogen.

[0044] The aforementioned control device may be equipped with a touch screen to facilitate operation of the control device.

[0045] The aforementioned control device can be controlled by a PLC (Programmable Logic Controller), and the control device can be equipped with a communication interface to enable communication connection between the control device and other devices.

[0046] The material conveyed by the feeder 1 can be weighed to a preset weight by the weighing tank 2, and then supplied to the blowing tank 3, thereby achieving precise downstream feeding. Furthermore, the separate installation of the weighing tank 2 and the blowing tank 3 effectively avoids interference from the pressure on the weighing device 22 during the blowing process, ensuring the accuracy of the weighing results from the weighing device 22 on the weighing tank 2 and thus improving the reliability of the aluminum granule feeding system. In addition, after the pressure valve 31 is opened, the weighed material can be quickly transported downstream by the high-pressure gas in the blowing tank 3, simplifying the mechanical connection structure between the blowing tank 3 and downstream equipment, such as the mechanical connection structure between the blowing tank 3 and the generator 6, effectively reducing the probability of failure and the frequency of maintenance in the aluminum granule feeding system.

[0047] In some embodiments, such as Figure 2 As shown, a first outlet valve 51 is provided at the outlet of the spray tank 3. When the first outlet valve 51 is in the open state, there is a preset gap between the valve core 54 and the valve body 55. The preset gap is used to block the material.

[0048] When the first outlet valve 51 is opened, its valve core moves from top to bottom, and the sealing gap expands rapidly with the valve opening, preventing metal particles from getting stuck between the valve core and the valve seat, thus effectively ensuring reliable unloading.

[0049] The aforementioned first outlet valve 51 is a full-bore valve, which ensures that there are no dead angles inside the first outlet valve 51 and effectively avoids the residue of metal particles.

[0050] The center of gravity of the first outlet valve 51 is located on the center line of the weighing tank 2 to ensure the weighing accuracy of the weighing tank 2.

[0051] In the above embodiment, by using the first outlet valve 51 installed on the feeding pipe 5, material can be prevented from getting stuck in the preset gap and accumulating at the outlet of the spray tank 3, thereby reducing the actual weight of the material added to the generator 6. Furthermore, this also reduces the failure rate of the aluminum granule feeding system and improves its safety and reliability.

[0052] The first outlet valve 51 is located downstream of the spray tank 3. Before the material is transported from the weighing tank 2 to the spray tank 3, the first outlet valve 51 can be closed to prevent the material from entering the feeding pipe 5 in advance, thereby causing material loss.

[0053] The size of the preset gap can be smaller than the diameter of the material, which effectively prevents the material from getting stuck in the preset gap and thus causing the material to accumulate at the first outlet valve 51.

[0054] In some embodiments, such as Figure 2 As shown, the valve core 54 of the first outlet valve 51 is eccentrically hemispherical in shape.

[0055] In the above embodiments, the first outlet valve 51 with an eccentric hemispherical valve core 54 can generate a strong shearing force between the valve core 54 and the valve body 55 to effectively squeeze and cut the material, thereby preventing the material from getting stuck in the preset gap and accumulating at the first outlet valve 51, further improving the safety and reliability of the aluminum granule feeding system.

[0056] In some embodiments, such as Figure 1 As shown, the aluminum granule feeding system also includes a protective pipe 7 and a generator 6 connected to both ends of the feeding pipe 5, respectively. The protective pipe 7 is used to deliver protective gas to the feeding pipe 5 and into the generator 6.

[0057] In the above embodiment, protective gas can be continuously supplied to the feeding pipe 5 through the protective pipe 7 to prevent the gas in the generator 6 from flowing back into the feeding pipe 5, thereby affecting the operating environment of the aluminum granule feeding system and the health of the user, effectively improving the safety and reliability of the aluminum granule feeding system.

[0058] During the material delivery to generator 6, generator 6 is in the open state. Gas inside generator 6 may flow back through feeding pipe 5 to weighing tank 2, spray tank 3, and other equipment, potentially affecting the aluminum granule feeding system and its operating environment. However, by continuously supplying protective gas to feeding pipe 5 through protective pipe 7, the gas pressure inside feeding pipe 5 can be kept higher than the gas pressure inside generator 6, thus preventing backflow of gas from generator 6. This protective gas can be nitrogen or other gases that do not readily undergo chemical reactions.

[0059] The aforementioned protective pipe 7 can be connected to the gas storage tank, and the pump body pressurizes and transports the gas in the gas storage tank through the protective pipe 7 to the feeding pipe 5.

[0060] The aforementioned protective pipe 7 can deliver protective gas at different stages of the aluminum granule feeding system to ensure the safety of the system. For example, protective gas can be delivered during the material conveying process of the feeder 1, or during the weighing process of the weighing tank 2.

[0061] In some embodiments, such as Figure 1 As shown, the feeding pipe 5 is also provided with a second outlet valve 52 and a first inlet valve 53 located downstream of the first outlet valve 51. The connection between the feeding pipe 5 and the protection pipe 7 is located between the second outlet valve 52 and the first inlet valve 53.

[0062] The outlet of the aforementioned blow-jet can 3 adopts a dual-valve design, namely a second outlet valve 52 and a first inlet valve 53. The second outlet valve 52 is a material-stopping valve, and the first inlet valve 53 is a sealing valve. During operation, the first inlet valve 53 can be opened first, followed by the second outlet valve 52. When closing, the second outlet valve 52 can be closed first, followed by the first inlet valve 53. This ensures the effective sealing of the outlet of the blow-jet can 3 by the first inlet valve 53, achieving reliable feeding and sealing.

[0063] The aforementioned second outlet valve 52 can be a butterfly valve, slide gate valve, rocker arm valve, disc valve, or other types of valve.

[0064] The first inlet valve 53 mentioned above can be a dome valve, ball valve, butterfly valve, or other types of valve.

[0065] In the above embodiments, by installing a second outlet valve 52 and a first inlet valve 53 in the feeding pipe 5, the airtightness of the feeding pipe 5 can be ensured. This guarantees the gas pressure inside the injection tank 3 while preventing the backflow of gas from the generator 6 into the injection tank 3. Furthermore, the valves also allow the injection tank 3 and the generator 6 to operate independently, facilitating the inspection and maintenance of the generator 6 and effectively improving the practicality of the aluminum granule feeding system.

[0066] The aforementioned second outlet valve 52 can be used to seal the injection tank 3, preventing pressure leakage when gas is supplied to the injection tank 3 for pressurization. Furthermore, it can also prevent gas from the generator 6 from flowing back into the injection tank 3.

[0067] The aforementioned first inlet valve 53 can be located upstream of the generator 6. The user can shut off the first inlet valve 53 to further prevent the gas in the generator 6 from flowing back into the spray canister 3. Furthermore, when the generator 6 malfunctions or requires maintenance, the user can shut off the first inlet valve 53 to isolate the generator 6 from other systems in the aluminum granule feeding system, thereby facilitating the replacement or maintenance of the generator 6.

[0068] In some embodiments, such as Figure 1 As shown, the control device is electrically connected to the first outlet valve 51, the second outlet valve 52 and the first inlet valve 53 respectively. The control device is also used to control the first inlet valve 53 to be in a normally open state, and to control the second outlet valve 52 and the first outlet valve 51 to open sequentially before the blowing tank 3 conveys material to the generator 6 through the feeding pipe 5.

[0069] In the above embodiments, the control device can control the first inlet valve 53 to be in a normally open state to prevent the gas in the generator 6 from flowing back into other equipment in the aluminum granule feeding system, such as the blowing tank 3 and the weighing tank 2. The control device can also control the second outlet valve 52 and the first outlet valve 51 to open sequentially before the blowing tank 3 conveys material to the generator 6, so that after the first outlet valve 51 is opened, the material in the blowing tank 3 can be quickly conveyed to the generator 6 through the feeding pipe 5, effectively ensuring the stability of the aluminum granule feeding system.

[0070] The first inlet valve 53 can be in a normally open state so that the protective gas in the protective pipeline 7 can be continuously and uninterruptedly delivered to the generator 6 through the feeding pipeline 5, effectively ensuring that the gas in the generator 6 flows back into the spray tank 3 through the feeding pipeline 5.

[0071] The first outlet valve 51 and the second outlet valve 52 mentioned above can be opened or closed according to actual usage.

[0072] For example, when the feeder 1 is feeding material into the weighing tank 2, or when the weighing tank 2 is weighing, the first outlet valve 51 and the second outlet valve 52 can be closed, and the first outlet valve 51 and the second outlet valve 52 can be closed sequentially. After the weighed material is conveyed to the spray tank 3, the control device can control the second outlet valve 52 and the first outlet valve 51 to open sequentially, so that the feeding pipe 5 is open, and then the material in the spray tank 3 is conveyed to the generator 6 through the feeding pipe 5.

[0073] In some embodiments, such as Figure 1 As shown, the blow-off tank 3 is also connected to an exhaust valve 32 that communicates with the inside of the tank. The control device is electrically connected to the exhaust valve 32. The control device is also used to send a control command to the exhaust valve 32 to open it before the weighing tank 2 feeds material into the blow-off tank 3.

[0074] In the above embodiment, the exhaust valve 32 can quickly discharge the residual gas in the blow-blown can 3 after the blow-blown can 3 completes one material conveying, so that the material can smoothly enter the blow-blown can 3 before the blow-blown can 3 conveys the next batch of material. This realizes the batch-by-batch delivery of material to the generator 6, ensuring that all the material weighed by the weighing tank 2 can enter the blow-blown can 3 and be delivered to the generator 6, further improving the reliability of the aluminum granule feeding system.

[0075] The aforementioned exhaust valve 32 can be installed in the exhaust gas path. After the blowing tank 3 completes one material delivery to the generator 6, the pressure of the residual gas in the blowing tank 3 is unfavorable for the next batch of material to enter the blowing tank 3. That is, if the pressure in the blowing tank 3 is too high, the material in the weighing tank 2 will be difficult to deliver to the blowing tank 3. By using the aforementioned exhaust valve 32, after completing one material delivery to the generator 6, the pressure in the blowing tank 3 can be reduced to the same or similar pressure as that in the weighing tank 2, so that the material weighed by the weighing tank 2 can smoothly and quickly enter the blowing tank 3.

[0076] Optionally, one end of the above-mentioned exhaust gas path can be connected to the external environment, or an exhaust pump can be installed to quickly release the gas in the injection tank 3.

[0077] The aforementioned spray tank 3 is also connected to a balance valve that communicates with the inside of the tank. The balance valve is used to adjust the pressure inside the spray tank 3 to enable feeding to downstream equipment.

[0078] In some embodiments, such as Figure 1As shown, the upper inlet of the spray tank 3 is connected to the lower outlet of the weighing tank 2 through the discharge pipe 8. The discharge pipe 8 is equipped with a third outlet valve 81, a second inlet valve 82 and a third inlet valve 83 in sequence. The third outlet valve 81 is located upstream of the second inlet valve 82 and the third inlet valve 83. The control device is electrically connected to the third outlet valve 81, the second inlet valve 82 and the third inlet valve 83 respectively. The control device is also used to control the third outlet valve 81 and the third inlet valve 83 to open before the weighing tank 2 discharges material into the spray tank 3, and then control the second inlet valve 82 to open, so that the material in the weighing tank 2 can enter the spray tank 3 through the discharge pipe 8.

[0079] The third outlet valve 81 of the weighing tank 2 adopts a lightweight design, ensuring the low weight of the weighing tank 2 and improving weighing accuracy. The third outlet valve 81 can adopt a bottom-opening valve core, and its sealing gap expands rapidly as the valve is opened, avoiding the phenomenon of aluminum particles getting stuck or spilling.

[0080] In the above embodiment, the material conveying between the weighing tank 2 and the blowing tank 3 can be controlled by controlling the opening and closing of the third outlet valve 81. The second inlet valve 82 and the third inlet valve 83 can ensure that the weighing tank 2 is not affected by the gas pressure inside the blowing tank 3, effectively ensuring the weighing accuracy of the weighing tank 2, thereby improving the reliability of the aluminum particle feeding system and avoiding the occurrence of safety accidents caused by the leakage of gas pressure inside the blowing tank 3.

[0081] The inlet of the aforementioned blow tank 3 adopts a dual-valve design, namely a second inlet valve 82 and a third inlet valve 83. The second inlet valve 82 is a material-stopping valve, and the third inlet valve 83 is a sealing valve. During operation, the third inlet valve 83 can be opened first, followed by the second inlet valve 82. When closing, the second inlet valve 82 can be closed first, followed by the third inlet valve 83. This ensures the effective sealing of the inlet of the blow tank 3 by the third inlet valve 83, achieving reliable feeding and sealing.

[0082] The second inlet valve 82 mentioned above can be a butterfly valve, slide gate valve, rocker arm valve, disc valve, or other types of valve.

[0083] The aforementioned third inlet valve 83 can be a dome valve, ball valve, butterfly valve, or other types of valve.

[0084] The aforementioned control device can keep the third outlet valve 81 closed to prevent material in the weighing tank 2 from falling into the discharge pipe 8 before or during weighing, thereby ensuring the accuracy of the weight of each batch of material. The aforementioned control device can also keep the third outlet valve 81 open so that the material can be transported to the spray tank 3 through the discharge pipe 8 after weighing.

[0085] A flexible connector 11 can be provided between the third outlet valve 81 and the second inlet valve 82 to achieve a flexible connection between the third outlet valve 81 and the second inlet valve 82, thereby reducing the possibility of interference with the weighing results of the weighing tank 2 and improving the weighing accuracy of the weighing tank 2.

[0086] The aforementioned third inlet valve 83 can be installed upstream of the inlet of the spray tank 3 to seal the spray tank 3, prevent the gas pressure inside the spray tank 3 from leaking into the discharge pipe 8, and thus ensure the pressure stability inside the tank body 21 of the spray tank 3.

[0087] The second inlet valve 82 can be located upstream of the third inlet valve 83 to protect the weighing tank 2 in case the third inlet valve 83 fails to seal properly, thus preventing the pressure of the gas in the spray tank 3 from affecting the weighing accuracy of the weighing tank 2.

[0088] In some embodiments, the first inlet valve 53 is configured as a high-temperature valve.

[0089] In the above embodiments, the high-temperature valve can isolate the high temperature generated by the generator 6 from the protective pipe 7, the spray tank 3 and other equipment, effectively avoiding interference or damage to other equipment in the aluminum granule feeding system, such as the weighing tank 2 and the water spray tank, and further improving the safety and reliability of the aluminum granule feeding system.

[0090] The first inlet valve 53 can be installed on the feeding pipe 5 and close to the generator 6. The temperature that the first inlet valve 53 can withstand is greater than 450 degrees Celsius.

[0091] In some embodiments, such as Figure 1 As shown, the aluminum granule feeding system also includes a feeding hopper 9. The upper opening of the feeding hopper 9 corresponds to the discharge port of the feeder 1, and the lower opening of the feeding hopper 9 corresponds to the upper inlet of the weighing tank 2, so that the discharge port of the feeder 1 supplies material to the upper inlet of the weighing tank 2 through the feeding hopper 9.

[0092] In the above embodiment, the feeding hopper 9 can supply all the material conveyed by the feeder 1 to the weighing tank 2, avoiding spillage before the material enters the weighing tank 2. This ensures that each batch of material conveyed by the feeder 1 can be adequately delivered to the generator 6, effectively improving the reliability and practicality of the aluminum granule feeding system. Furthermore, the upper opening of the feeding hopper 9 can be larger than the lower opening, allowing the feeding hopper 9 to better receive the material from the pneumatic feeder 1 and quickly deliver the material to the weighing tank 2.

[0093] A flexible connector 11 can be provided between the feeding hopper 9 and the feeder 1. The flexible connector 11 can prevent the vibration generated by the feeder 1 during operation from being transmitted to the feeding hopper 9, thereby preventing the material from falling out of the feeding hopper 9. This effectively ensures that the material can fall smoothly into the feeding hopper 9.

[0094] The following is a detailed explanation of the batch material feeding process for the aluminum granule feeding system: First, before feeding materials into the aluminum granule feeding system, a self-inspection step is performed. After confirming that the system passes the self-inspection and can operate normally, a feeding plan can be set, such as the feeding weight per unit time and the number of feedings. After calculating the single feeding weight and feeding interval based on the set feeding plan, the material weighing step, the weighing and unloading step, and the aluminum granule feeding step can be executed sequentially. Feeding can be stopped after the feeding is completed, and then a delay is waited until the aforementioned feeding interval is reached before continuing the next material weighing step, weighing and unloading step, and aluminum granule feeding step, until the feeding process for all batches is completed according to the set feeding plan.

[0095] like Figure 1 Before feeding the aluminum granules into the feeding system, the second isolation valve 12, the first isolation valve 10, and the protective pipe 7 are opened sequentially. The material in the hopper 4 falls into the feeder 1 by gravity. The feeder 1 then conveys the material to the weighing tank 2 through the discharge funnel 9. After that, the second isolation valve 12 is closed and the material is weighed. When the weight of the material in the weighing tank 2 meets the preset weight, the weighing of the material in the weighing tank 2 is considered complete.

[0096] The following is a detailed explanation of the above weighing and unloading steps: (Combined with...) Figure 1 After weighing the material in weighing tank 2, the exhaust valve 32, the third inlet valve 83, the second inlet valve 82 and the third outlet valve 81 can be opened in sequence. Then the weight of weighing tank 2 returns to zero, and the third outlet valve 81, the second inlet valve 82 and the third inlet valve 83 are closed in sequence. This completes the above weighing and unloading steps, so that all the material in weighing tank 2 enters the blowing tank 3.

[0097] The following is a detailed explanation of the above aluminum granule feeding steps: (Combined with...) Figure 1 After completing the weighing and feeding steps described above, the exhaust valve 32 can be closed and the pressure valve 31 can be opened. Once the pressure inside the spray tank 3 reaches the preset pressure, the pressure valve 31 can be closed. Then, the second outlet valve 52 and the first outlet valve 51 can be opened in sequence. At this time, the first inlet valve 53 is in the normally open state, thereby enabling the supply of materials to the generator 6 via the spray tank 3.

[0098] After the above aluminum granule feeding steps are completed, the first inlet valve 53, the second outlet valve 52 and the first outlet valve 51 can be closed in sequence, thus completing the feeding of one batch of materials in the aluminum granule feeding system.
