Description

Technical Field

[0001] This application belongs to the technical field of industrial purification, specifically a tubular filter box in a refining workshop. Background Art

[0002] The refining workshop is an area specifically designed in industrial production to control air quality and environmental conditions, ensuring that the product quality during the production process meets high standards. It is usually equipped with efficient air filtration systems and temperature and humidity control equipment to remove dust, pollutants, and other factors in the air that may affect product quality. The refining workshop is widely used in industries such as pharmaceuticals, electronics, and food processing. Its goal is to create a clean and stable production environment and improve the consistency and reliability of products.

[0003] As the final filtration method on the aluminum or aluminum alloy casting line, the tubular filter box effectively filters impurities in the molten aluminum and improves the quality of the molten aluminum. Traditional tubular filter boxes only have a filtering function and lack degassing and refining treatment of the molten aluminum, which easily results in a relatively high hydrogen content in the molten aluminum and affects the quality of the molten aluminum. Currently, in the field of aluminum or aluminum alloy purification treatment, breathable bricks are also applied to equipment such as holding furnaces, melting furnaces, degassing boxes, plate filter boxes, and launders, but there is currently no application of breathable bricks to tubular filter boxes.

[0004] However, the inlets and outlets of traditional tubular filter boxes are open spaces. The molten aluminum reacts with oxygen in the air to form an alumina film, and reacts with water vapor in the air to produce hydrogen and oxides, etc. These alumina films, hydrogen, and oxides are all mixed in the molten aluminum, thereby reducing the product quality. Summary of the Utility Model

[0005] The purpose of this application is to provide a tubular filter box in a refining workshop to solve the problem that the inlets and outlets of the traditional tubular filter box are open spaces, where the molten aluminum reacts with oxygen in the air to form an alumina film, and reacts with water vapor in the air to produce hydrogen and oxides, etc. These alumina films, hydrogen, and oxides are all mixed in the molten aluminum, thereby reducing the product quality.

[0014] In a preferred embodiment, a mounting block is installed on the outer surface of one side of the main body of the tubular filter box, and a sealing door is arranged on one side of the mounting block.

[0015] By adopting the above technical solutions, the main body of the tubular filter box can be opened through the sealing door, which is convenient for disassembling and assembling the straight tube filter cartridge inside the main body of the tubular filter box and for cleaning, improving the convenience of use.

[0016] In a preferred embodiment, a sealing plate is inserted into the inside of one side of the mounting block.

[0017] By adopting the above technical solutions, the mounting block is sealed by the sealing plate, improving the sealing performance.

[0018] In a preferred embodiment, sealing gaskets are bonded to the upper and lower ends of the sealing plate.

[0019] By adopting the above technical solutions, the friction between the sealing plate and the mounting block is increased, and further the sealing performance of the sealing plate to the mounting block is improved.

[0020] In summary, due to the adoption of the above technical solutions, the beneficial effects of this application are:

[0021] 1. Heat the inside of the sealing device through a heating block to evaporate the moisture in the internal air and keep it dry inside. Use an air pump to extract the inert gas inside the gas storage cavity through the inner air pipe, and then transport it to the inside of the sealing device through the air pipe, so that the inside of the sealing device is filled with inert gas, and the air is discharged from the inside of the sealing device.

Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0029] Refer to Figures 1-3, The tubular filter box in the refining workshop includes the main body 1 of the tubular filter box. A lower pipe 2 is arranged at the lower end of the main body 1 of the tubular filter box, and an upper pipe 9 is arranged at the upper end of the main body 1 of the tubular filter box. A sealing device 6 is arranged inside the lower pipe 2 and the upper pipe 9. An air pump device 7 is installed on the outer surface of the sealing device 6. An air pump 13 is installed inside the air pump device 7. One end of the air pump 13 is provided with an air pipe 10, and the other end of the air pipe 10 is communicated with the sealing device 6. Through the above design, the inside of the sealing device 6 is filled with inert gas, reducing the chance of oxygen contacting the molten aluminum above the molten aluminum, thereby reducing the generation of oxides of the molten aluminum and improving the quality of the molten aluminum.

[0030] Refer to Figures 1-2 , An upper solenoid valve 8 is installed at the upper end of the sealing device 6, and a lower solenoid valve 5 is installed at the lower end of the sealing device 6, which can automatically open and close the upper pipe 9 and the lower pipe 2, facilitating use and improving the convenience of use.

[0031] Refer to Figures 1-3 , An air storage cavity 15 is formed inside the upper end of the air pump device 7. One end of the air pump 13 is provided with an inner air pipe 14, and the other end of the inner air pipe 14 is communicated with the air storage cavity 15. The inert gas is stored through the air storage cavity 15, facilitating use and enabling its recycling.

[0032] Refer to Figure 3 , A heating block 12 is installed on the inner wall of the sealing device 6. The inside of the sealing device 6 is heated through the heating block 12 to evaporate the moisture inside and keep it dry, reducing the generation of hydrogen.

[0033] Refer to Figures 1-2 and Figure 4 , A mounting block 4 is installed on the outer surface of one side of the main body 1 of the tubular filter box. A sealing door 3 is arranged on one side of the mounting block 4. The main body 1 of the tubular filter box can be opened through the sealing door 3, facilitating the disassembly and assembly of the straight tube filter element inside the main body 1 of the tubular filter box and cleaning, improving the convenience of use.

[0034] Refer to Figure 2 and Figure 4 , A sealing plate 11 is inserted inside one side of the mounting block 4 to seal the mounting block 4 and improve the sealing performance.

[0035] Refer to Figure 4 , Sealing gaskets are bonded to the upper and lower ends of the sealing plate 11 to increase the friction between the sealing plate 11 and the mounting block 4, thereby improving the sealing performance of the sealing plate 11 to the mounting block 4.

[0036] The implementation principle of the tubular filter box in the refining workshop of this application is as follows:

[0037] When in use, the inside of the sealing device 6 is heated by the heating block 12 to evaporate the moisture in the internal air and keep it dry inside. The inert gas inside the gas storage cavity 15 is extracted by the air pump 13 through the inner air pipe 14, and then conveyed to the inside of the sealing device 6 through the air pipe 10, so that the inside of the sealing device 6 is filled with inert gas, and the air is discharged from the inside of the sealing device 6. Furthermore, the sealing device 6 is sealed by the upper solenoid valve 8 to avoid the negative impact of hydrogen generated during the reaction on the reaction. When the work is finished, the lower end of the sealing device 6 is sealed by the lower solenoid valve 5. Again, the remaining inert gas inside the sealing device 6 can be extracted by the air pump 13 and conveyed to the inside of the gas storage cavity 15 for storage, reducing the loss of inert gas. In addition, when it is necessary to maintain and clean the straight tube filter cartridge inside the tubular filter box body 1, the sealing plate 11 is slid out of the inside of the mounting block 4, and the sealing door 3 is opened, then the straight tube filter cartridge can be maintained and cleaned to ensure the working effect of the tubular filter box body 1.
