Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically, to a low-resistance detachable filter. Background Technology

[0002] Low-resistance filters are filtration devices designed to reduce the resistance of fluids (liquids or gases) to flow. While ensuring basic filtration efficiency, they reduce pressure loss during fluid flow through structural optimization. They are widely used in scenarios requiring efficient flow and impurity filtration, such as ventilation systems, water treatment pipelines, and industrial circulation equipment.

[0003] The utility model patent publication number is CN209576086U. This utility model relates to the field of filter technology, specifically to a high-temperature resistant high-efficiency filter, which includes a hollow rectangular columnar frame. Outer frames are provided on the outer sides of both ends of the frame, and the outer frames are welded to the frame. A ventilated filter layer is provided through the middle of the frame. Protective mesh is provided on both sides of the filter layer. A filter element is provided between the protective mesh and the filter layer. This design effectively achieves sealing protection between the outer frame and the frame, preventing damage to the frame's edge from causing a leak in the filter's sealing structure. The simple structure further improves the frame's strength, making the frame's edge less prone to damage and thus extending its service life.

[0004] While the aforementioned equipment can effectively achieve sealing protection between the outer frame and the frame, preventing damage to the frame from causing a leak in the filter's sealing structure, and its simple structure further improves the frame's strength, making the frame less prone to damage and thus extending its service life, the filter screen relies heavily on rigid connections such as bolts and clips for installation. Disassembly requires tools to disassemble it one by one, and installation requires repeated calibration and positioning, making the operation cumbersome, especially in confined spaces or frequent maintenance scenarios, increasing the manual burden.

[0005] Therefore, we have made improvements to this by proposing a low-resistance, removable filter. Utility Model Content

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The mounting assembly 9 includes a first spring 901, which is fixedly mounted on the top of the inner cavity of the connecting shell 7. A baffle 902 is fixedly mounted on the bottom of the first spring 901. Two grooves 903 are opened on the front side of the baffle 902. An extrusion rod 904 is fixedly mounted on the bottom of the baffle 902. The bottom of the extrusion rod 904 extends through to the bottom of the mounting plate 6 and cooperates with the extrusion groove 4. Mounting assembly 9 also includes a second spring 905, which is fixedly installed on the rear side of the inner cavity of mounting plate 6. A movable plate 906 is fixedly installed on the front side of the second spring 905. Two first fixing brackets 907 are fixedly installed on the front side of the movable plate 906. A connecting plate 908 is movably connected to the inner cavity of the first fixing bracket 907 via a pivot. A second fixing bracket 909 is movably connected to the side of the connecting plate 908 away from the first fixing bracket 907 via a pivot. A push plate 910 is fixedly installed on the opposite side of each of the two second fixing brackets 909. Two limiting rods 911 are fixedly installed on the opposite side of each of the two push plates 910. One side of the limiting rod 911 extends through to one side of the mounting plate 6 and cooperates with the limiting groove 5. Movable rods 917 are fixedly installed on both sides of the front side of the movable plate 906. The movable rods 917 cooperate with the grooves 903. A pull rod 918 is fixedly installed on the top of the movable plate 906. The top of the pull rod 918 extends through the sliding groove 13 to the top of the mounting plate 6. Sliding blocks 912 are fixedly installed on both sides of the baffle 902. A sliding rod 913 is slidably connected to the inner cavity of the sliding block 912. The top and bottom of the sliding rod 913 are fixedly connected to the mounting plate 6 and the connecting shell 7, respectively. Two limiting blocks 914 are fixedly installed on the top and bottom of the movable plate 906. The limiting blocks 914 are slidably connected to the inner cavity of the mounting plate 6. Positioning blocks 915 are fixedly installed on the front and rear sides of the push plate 910. A positioning rod 916 is slidably connected to the inner cavity of the positioning block 915. The side of the positioning rod 916 closest to the mounting plate 6 is fixedly connected to the mounting plate 6. Sealing rings 10 are fitted onto the surfaces of the feed pipe 2 and the discharge pipe 3. The side of the sealing ring 10 closest to the filter body 1 is fixedly connected to the filter body 1. Multiple sealing grooves 11 are opened on the front and rear sides of the inner cavity of the filter body 1. Sealing plates 12 are fixedly installed on the front and rear sides of the filter screen 8. The sealing grooves 11 and the sealing plates 12 cooperate with each other.The mounting plate 6 is lowered with the top opening of the filter body 1 aligned with it, so that the extrusion rod 904 contacts the extrusion groove 4 of the filter body 1 and is compressed. The extrusion rod 904 moves upward under force, causing the baffle 902 to move upward synchronously. The baffle 902 compresses the first spring 901, which is in a stored energy state at this time. During the movement of the baffle 902, the groove 903 on one side gradually aligns with the movable rod 917 on one side of the movable plate 906. When the groove 903 aligns with the movable rod 917, the second spring, which was originally in a compressed state, is released. 905 rebounds, pushing the movable plate 906 forward. The movable rod 917 moves synchronously with the movable plate 906 and slides into the groove 903. The groove 903 provides movement space for the movable rod 917. When the movable plate 906 moves, the first fixed frame 907 on its front side drives the second fixed frame 909 to move through the connecting plate 908. The second fixed frame 909 pushes the push plate 910 to move to both sides. The push plate 910 drives the limiting rod 911 to move synchronously to the outside of the mounting plate 6, finally causing the limiting rod 911 to embed into the limit of the filter body 1. Within the slot 5, the mounting plate 6 and the filter screen 8 are fixed. During disassembly, pull the pull rod 918 backward. The pull rod 918 moves along the sliding groove 13, causing the movable plate 906 to move backward. The movable plate 906 compresses the second spring 905, which is in a stored-energy state. When the movable plate 906 moves, it drives the push plate 910 to move inward toward the mounting plate 6 via the first fixing frame 907, connecting plate 908, and second fixing frame 909. The limiting rod 911 moves synchronously with the push plate 910 and disengages from the limiting groove 5, releasing the pressure. With the mounting plate 6 fixed, remove the mounting plate 6 upwards. At this time, the extrusion rod 904 is released from the constraint of the extrusion groove 4, and the first spring 901 rebounds, pushing the baffle 902, the groove 903 and the extrusion rod 904 to reset downwards. During the reset process of the baffle 902, one side wall of it gradually contacts the movable rod 917 and blocks the movement of the movable rod 917, so that the movable plate 906 cannot reset under the action of the second spring 905. The limiting rod 911 remains in the state of being retracted into the inner cavity of the mounting plate 6 to prevent the parts from being exposed after disassembly. The four filter screens 8 are at the bottom of the filter body 1.

[0030] During operation, the mounting plate 6 is aligned with the top opening of the filter body 1 and lowered, causing the extrusion rod 904 to contact the extrusion groove 4 of the filter body 1 and be compressed. The extrusion rod 904 moves upward under force, causing the baffle 902 to move upward synchronously. The baffle 902 compresses the first spring 901, which is in a stored energy state at this time. During the movement of the baffle 902, the groove 903 on one side gradually aligns with the movable rod 917 on one side of the movable plate 906. When the groove 903 aligns with the movable rod 917, the baffle 902, which was originally in a compressed state, is now in a compressed state. The second spring 905 rebounds, pushing the movable plate 906 forward. The movable rod 917 moves synchronously with the movable plate 906 and slides into the groove 903. The groove 903 provides movement space for the movable rod 917. When the movable plate 906 moves, the first fixing frame 907 on its front side drives the second fixing frame 909 to move through the connecting plate 908. The second fixing frame 909 pushes the push plate 910 to move to both sides. The push plate 910 drives the limiting rod 911 to move synchronously to the outside of the mounting plate 6, finally causing the limiting rod 911 to embed into the filter body. Within the limiting groove 5 of 1, the mounting plate 6 and the filter screen 8 are fixed. During disassembly, pull the pulling rod 918 backward. The pulling rod 918 moves along the sliding groove 13, causing the movable plate 906 to move backward. The movable plate 906 compresses the second spring 905, which is in a stored-energy state. When the movable plate 906 moves, it drives the pushing plate 910 to move inward toward the mounting plate 6 via the first fixing frame 907, connecting plate 908, and second fixing frame 909. The limiting rod 911 moves synchronously with the pushing plate 910 and disengages from the limiting groove 5. Except for the fixing of the mounting plate 6, the mounting plate 6 is taken out upward. At this time, the extrusion rod 904 is released from the constraint of the extrusion groove 4, the first spring 901 rebounds, and pushes the baffle 902, the groove 903 and the extrusion rod 904 to reset downward. During the reset process of the baffle 902, one side wall of it gradually contacts the movable rod 917 and blocks the movement of the movable rod 917, so that the movable plate 906 cannot reset under the action of the second spring 905. The limiting rod 911 remains in the state of being retracted into the inner cavity of the mounting plate 6 to avoid the parts being exposed after disassembly. The four filter screens 8 are at the bottom of the filter body 1.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
