Description

Technical Field

[0001] This utility model relates to the field of tubular filter technology, specifically to tubular filters for filtering aluminum and aluminum alloy melts. Background Technology

[0002] Tubular filters are an important piece of equipment used in the production of aluminum and aluminum alloys. They are used to remove inclusions and impurities from the molten aluminum to improve the quality of the aluminum alloys. Tubular filters used in the filtration and purification of aluminum and aluminum alloy molten aluminum have advantages such as good filtration efficiency, long service life, heating devices to prevent aluminum solidification, and flexible design.

[0003] Upon investigation, we found an aluminum alloy melt tubular filter with publication number CN204380355U, which includes a filter housing and a filter tank housed within the filter housing. This filter is designed to address the problem of clogging, particularly in narrower sections like the filter tubes, after prolonged use. However, the filter tube section in this practical application lacks a separate disassembly and assembly structure, making the disassembly and replacement of the filter tubes and tube supports inconvenient and hindering maintenance and adjustment based on filtration requirements. Consequently, its applicability is limited. Therefore, we propose a tubular filter for aluminum and aluminum alloy melt filtration. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides an improved tubular filter for filtration of aluminum and aluminum alloy melts. Please refer to [link to relevant documentation]. Figures 1-3 The system includes: a filter box 1, a cover 2 at the top of the filter box 1, the cover 2 being threadedly connected to the filter box 1, a cover plate 3 fixed to the inner side of the cover 2, a filling port 4 on the middle surface of the cover plate 3, a primary filter plate 5 laid on the upper end of the filter box 1, and the cover 2 being connected to the filter box 1 through the filling port 4 and the primary filter plate 5. The primary filter plate 5 is placed below the filling port 4 to increase the total filtration capacity of the tubular filter and extend the service life of the filter tubes 9; a partition 6 fixed to the inner surface of the lower end of the filter box 1, and a permeable brick 7 laid on the upper end of the partition 6, which can increase the total filtration capacity of the tubular filter and extend its service life; and pipe supports 8 installed on the upper ends of both sides of the partition 6, with filter tubes 9 installed on the inner side of the pipe supports 8, and the filter tubes 9 and the pipe supports 8 forming a detachable structure, with the filter tubes 9 evenly distributed along the inner side of the pipe supports 8. The filter tube 9 is connected to the filter box 1 by the tube frame 8. The filter tube 9 is securely held inside the filter box 1 by the tube frame 8, which facilitates the filtration of molten aluminum or aluminum alloy through the tube wall after it flows into the filter box 1. A discharge port 10 is provided at the connection between the filter tube 9 and the tube frame 8. A discharge pipe 11 is connected to the outer wall of the filter box 1 near the discharge port 10. A pipe valve 12 is installed in the middle of the discharge pipe 11. The filter tube 9 is connected to the discharge pipe 11 through the discharge port 10 and the pipe valve 12. The discharge pipe 11 outputs the filtered aluminum and aluminum alloy molten material through the filtration effect of the filter tube 9. The detachable and hoistable tube frame 8 and filter tube 9 facilitate replacement and maintenance after a period of use. The filter tube 9 inside the tube frame 8 can be adjusted according to the filtration requirements, making it more suitable for filtering various aluminum and aluminum alloy molten materials.

[0021] Please see Figure 2A tubular filter for filtering molten aluminum and aluminum alloys includes: heat-insulating gaskets 13 are provided on the outer walls of both ends of the inlet 4. The heat-insulating gaskets 13 are symmetrically arranged about the central axis of the inlet 4. The heat-insulating gaskets 13 are used to reduce the damage to the inlet 4 caused by molten aluminum or aluminum alloy when passing through the inlet 4; a sealing plate 14 is installed on the top outer wall of the cover 2 by bolts, and the sealing plate 14 forms a semi-enclosed structure between the cover 2 and the inlet 4. The sealing plate 14 is used to provide isolation protection for the filter box 1 and its internal structure when the filter is not in use, and to reduce the impact of external impurities or pollutants on the filter box 1.

[0022] Please see Figures 1-2 A tubular filter for filtering aluminum and aluminum alloy melts includes: Rotary seats 15 are embedded in both outer walls of a filter box 1 via bearings; a hydraulic rod 16 is bolted to the other end of the rotary seat 15; a side sealing plate 17 is connected to the telescopic end of the hydraulic rod 16 via the rotary seat 15; the side sealing plate 17 is hinged to the lower outer wall of the filter box 1; the side sealing plate 17 is rotatably connected to the filter box 1 via the telescopic end of the hydraulic rod 16 and the rotary seat 15; the side sealing plate 17 is mounted on the filter box 1 via the telescopic end of the hydraulic rod 16 and the rotary seat 15. The side can be rotated so that the side sealing plate 17 can be securely closed or rotated open as needed; a fireproof gel 18 is installed on the inner side of the bottom of the filter box 1, and the side sealing plate 17 forms an enclosing structure between the filter box 1 and the fireproof gel 18. The fireproof gel 18 is normally installed at the bottom of the filter box 1 and is surrounded and protected by the filter box 1 and the closed side sealing plate 17. It is used to provide fire protection at the bottom of the filter box 1 after the molten aluminum or aluminum alloy ablates through the partition 6, which facilitates the handling by the staff and improves the production safety.

[0023] Working Principle: For this type of tubular filter used for filtering molten aluminum and aluminum alloys, the operator first places the filter box 1 on a stable, level working surface to prevent the filter box 1 from shaking during filtration. Then, the hydraulic rod 16 is activated, causing the extension end of the hydraulic rod 16 to open the side sealing plate 17 at the lower end of the filter box 1 under the action of the rotating seat 15. Next, the operator fills the lower part of the filter box 1 with fire-retardant gel 18, which provides safety protection to prevent the molten aluminum or aluminum alloy from burning the partition 6 and creating a fire hazard. Finally, the box cover 2 is fastened to the upper part of the filter box 1, and the molten aluminum and aluminum alloy to be filtered passes through the partition... The hot gasket 13 is injected into the filter box 1 through the injection port 4. After preliminary filtration by the primary filter plate 5, it undergoes fine filtration through the filter tube 9. With the auxiliary filtration function of the permeable brick 7 on the partition plate 6, the outlet 10 outputs high-purity aluminum and aluminum alloy melt. Finally, the filtered melt output from the outlet 10 is discharged from the discharge pipe 11 through the open pipe valve 12, which is convenient for operators to collect according to their needs. After a period of operation, the filter tube 9 can be easily disassembled and replaced by the staff by opening the box cover 2 and using the hoisting pipe rack 8. This makes it easy to maintain and use, and can ensure the filtration effect for different filtration needs.
