Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, in particular to a multi-layer anti-oxidation filter bag. Background Art

[0002] Most existing filter bags are single-layer structures, which causes particle impurities of different sizes to pile up together, which in turn causes the inner wall of the filter bag to be quickly blocked, thereby increasing the frequency of cleaning and replacement of the filter bag. In addition, since there is no supporting component inside, it cannot maintain its own shape, which causes the filter bags to pile up during use, making the air circulation path too narrow, thereby affecting the efficiency of air filtration. For this reason, we propose a multi-layer antioxidant filter bag. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As mentioned in the background technology, most of the filter bags in the prior art are single-layer structures, which causes the particle impurities of different sizes to pile up together, which in turn causes the inner wall of the filter bag to be quickly blocked, thereby increasing the frequency of cleaning and replacement of the filter bag. In addition, since there is no supporting component inside, it cannot maintain its own shape, which causes the filter bag to pile up during use, making the air circulation path too narrow, thereby affecting the air filtration efficiency. The utility model proposes a multi-layer anti-oxidation filter bag.

[0023] Example 1

[0024] Reference Figures 1 to 3 The multi-layer anti-oxidation filter bag comprises a filter cartridge 1 and a filter bag 2 located outside the filter cartridge 1. In order to improve the service life, the filter cartridge 1 is made of stainless steel, and the filter bag 2 is woven from polytetrafluoroethylene fiber wire, which is resistant to high temperature, oxidation and corrosion.

[0025] The filter cartridge 1 is connected with a mounting plate 3, which is used to connect with the gas transmission pipeline, so that the gas enters the filter cartridge 1 through the mounting plate 3 for filtration. The filter aperture of the filter cartridge 1 is larger than the filter aperture of the filter bag 2, so that large particles of impurities in the gas remain in the filter cartridge 1, and small particles of impurities remain in the filter bag 2, thereby avoiding the problem that particles of different sizes are piled up together, causing the inner wall of the filter bag 2 to be quickly blocked. The filter bag 2 is connected with an annular connecting cloth 4;

[0026] A fixing component is provided on the mounting plate 3, and the fixing component is used to fix the connecting cloth 4 on the mounting plate 3;

[0027] The inner wall of the filter bag 2 is in contact with the support assembly.

[0028] The fixing component includes an electric guide rail 5 powered and controlled by the existing technology. A guide rod 6 is provided on the output end of the electric guide rail 5. A fixing ring 7 is provided on the guide rod 6. The fixing ring 7 is located on the outside of the filter bag 2. The left side of the fixing ring 7 is in contact with the connecting cloth 4. The left side of the connecting cloth 4 is in contact with the mounting plate 3. After the connecting cloth 4 is pressed against the mounting plate 3, the fixing ring 7 on the guide rod 6 is driven to move to the left by the electric guide rail 5, so that the connecting cloth 4 can be fixed, and then the filter bag 2 can be fixed.

[0029] The electric guide rail 5 is arranged on the mounting plate 3 , and the right end of the electric guide rail 5 extends to the right side of the filter bag 2 , so that the fixing ring 7 can be moved to the right side of the filter bag 2 without affecting the subsequent cleaning and replacement of the filter bag 2 .

[0030] The supporting assembly includes evenly arranged connecting rods 9 and curved rods 10, which are connected to each other, and the left side of the connecting rod 9 at the left end is connected to a micro-electric telescopic rod 8, and four micro-electric telescopic rods 8 are arranged, and the curved rods 10 on all sides are located on the outside of the filter cartridge 1, and the inner wall of the filter bag 2 is in contact with the curved rods 10 on all sides. The connected connecting rods 9 are driven by the micro-electric telescopic rods 8 to move, so that the curved rods 10 and all the connecting rods 9 are moved, and then the curved rods 10 are moved in a direction away from the filter cartridge 1 to support the filter bag 2 and maintain the shape of the filter bag 2, thereby avoiding stacking during use and ensuring the air circulation path. In addition, a connecting rod 9 is arranged so that multiple curved rods 10 can be connected, and then multiple curved rods 10 are used to ensure multi-point support for the filter bag 2, and to avoid excessive obstruction to the filtration of the filter bag 2.

[0031] In order to facilitate the installation of the micro electric telescopic rod 8 , grooves 11 are evenly opened on the right side of the mounting plate 3 , and the micro electric telescopic rod 8 is arranged in the groove 11 .
