Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridges, in particular to an integrated multi-angle filter cartridge with multi-stage filtration. Background Technique

[0002] With the rapid development and application of advanced technologies, the requirements for fluids in both life and industrial production are getting higher and higher, especially in industries such as water treatment, chemical engineering, pharmaceuticals, and food. Filter cartridges, as commonly used filtration equipment in the liquid treatment process, have been widely used. Conventional filter cartridge products are all single-stage filtration, and the filtration form is relatively single, which limits the scope of use of the filter cartridges.

[0003] Most of the existing multi-stage filtration filter cartridges are in the shape of blades, and the gaps between multiple blade-shaped filter leaves are relatively small. As a result, the setting of the filtration pore size of the filter cartridge is restricted, and the liquid passing through the pores is not easily discharged, leading to a relatively large amount of filtered liquid remaining in the filter cartridge, affecting the overall filtration effect of the filter cartridge. In addition, the installation between the filter cartridge and the external filter cylinder mostly uses bolt fixation, which is relatively troublesome for subsequent disassembly and replacement of the filter cartridge. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an integrated multi-angle filter cartridge with multi-stage filtration, which solves the problems that most of the existing multi-stage filtration filter cartridges are in the shape of blades, the gaps between multiple blade-shaped filter leaves are relatively small, the setting of the filtration pore size of the filter cartridge is restricted, the liquid passing through the pores is not easily discharged, resulting in a relatively large amount of filtered liquid remaining in the filter cartridge, affecting the overall filtration effect of the filter cartridge, and the installation between the filter cartridge and the external filter cylinder mostly uses bolt fixation, which is relatively troublesome for subsequent disassembly and replacement of the filter cartridge.

[0026] Please refer to Figures 1 - 4

[0027] Example 1: An integrated multi - angled filter element with multi - stage filtration, including a multi - angled filter element body 1. An external filter cylinder 2 is arranged on the outer side of the multi - angled filter element body 1. A top connection ring 3 is arranged at the top of the multi - angled filter element body 1. A bottom mounting block 4 is arranged at the bottom of the multi - angled filter element body 1. An installation block limit - fixing component 5 for limit - fixing is arranged on the bottom mounting block 4. A filter element quick - disassembly fixing component 6 for quick disassembly and fixing is arranged at the top of the external filter cylinder 2. A liquid discharge port 7 is arranged at the bottom of the side of the external filter cylinder 2.

[0028] The installation block limit - fixing component 5 includes an annular limit groove 501 opened on the side of the bottom mounting block 4. Two limit contact balls 502 are symmetrically arranged on both sides of the bottom mounting block 4. The side of the limit contact ball 502 abuts against the annular limit groove 501. The bottom end of the limit contact ball 502 is fixedly connected to the external filter cylinder 2 through a set fixing connecting rod 503. A rotating groove 504 is opened in the middle of the bottom end of the external filter cylinder 2. A semi - circular abutting block 505 is arranged in the middle of the bottom end of the bottom mounting block 4. The semi - circular abutting block 505 is inserted into the rotating groove 504.

[0029] The filter element quick - disassembly fixing component 6 includes a top opening 601 opened at the top of the external filter cylinder 2. A fixed closing plate 602 is inserted into the top opening 601. A middle opening 603 is opened in the middle of the fixed closing plate 602. The top end of the top connection ring 3 penetrates through the middle opening 603. Two side slots 604 are symmetrically opened on both side walls of the fixed closing plate 602. Two pulling through holes 605 are symmetrically opened on both sides of the external filter cylinder 2. Two inner cavity grooves 606 are symmetrically arranged on both sides of the inner wall of the pulling through hole 605. A connecting plug rod 607 is slidably inserted into the pulling through hole 605. The end of the connecting plug rod 607 is inserted into the side slot 604. Two pushing connection blocks 608 are symmetrically arranged on both sides of the rod body of the connecting plug rod 607. A fixed spring 609 is arranged in the inner cavity groove 606. One end of the fixed spring 609 is connected to the pushing connection block 608, and the other end of the fixed spring 609 is connected to the inner wall of the inner cavity groove 606. A pull ring 610 is connected to the end of the connecting plug rod 607.

[0030] Example 2: The difference between this example and Example 1 is that the blades around the multi - angled filter element body 1 are inclined at 10°.

[0031] The distance between the blades around the multi - angled filter element body 1 is greater than the distance between the blades of an ordinary filter element, so that the distance between the filter mesh holes on the blades is larger, making it easier to filter and discharge the liquid inside the multi - angled filter element body 1.

[0032] Two limit slots are symmetrically opened on both sides of the top of the external filter cylinder 2. A limit plug block is arranged at the bottom end of the side of the fixed closing plate 602.

[0033] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the end of the connecting plug rod 607 is in an inclined shape that is convenient for insertion.

[0034] The end of the connecting plug rod 607 can be more conveniently inserted into the side slot 604 to abut and fix the fixed closing plate 602.

[0035] Embodiment 4: The difference between this embodiment and Embodiment 1 is that the opening at the end of the pulling perforation 605 is larger than the diameter of the pull ring 610.

[0036] The pull ring 610 and the connecting plug rod 607 can be inserted into the pulling perforation 605, and it is convenient for the user to pull the pull ring 610.

[0037] In this embodiment, since most of the existing multi-stage filter cartridges are in the shape of blades, and the gaps between multiple blade-shaped filter leaves are small, the setting of the filter pore size of the filter cartridge is restricted, and the liquid passing through the pores is not easily discharged, resulting in more filtered liquid remaining in the filter cartridge, affecting the overall filtration effect of the filter cartridge. Moreover, the installation between the filter cartridge and the external filter cylinder mostly uses bolt fixation, which is relatively troublesome for subsequent disassembly and replacement of the filter cartridge.

[0038] In summary, in specific implementation, by setting the multi-angle filter cartridge body 1 such that the surrounding blades are inclined at 10°, a multi-angle arrangement is formed between the blades, the distance between the blades is greater than the distance between the ordinary filter cartridge blades, and the distance between the filter mesh holes on the blades is larger, so that it is easy to filter and discharge the liquid inside the multi-angle filter cartridge body 1 to improve the filtration efficiency of the liquid passing through the multi-angle filter cartridge body 1.

[0039] An installation block limit fixing assembly 5 is provided at the bottom of the multi-angle filter cartridge body 1. The semi-circular abutting block 505 in the installation block limit fixing assembly 5 can be limited by the rotation groove 504 and supported and abutted by the limit abutting ball 502 on the side of the annular limit groove 501, so that the bottom installation block 4 at the bottom end of the multi-angle filter cartridge body 1 can be firmly and stably inserted into the external filter cylinder 2. For the fixation of the top end of the multi-angle filter cartridge body 1, a filter cartridge easily detachable fixing assembly 6 is provided at the top of the external filter cylinder 2, and the top connecting ring 3 is limited and fixed by the middle opening 603 provided in the middle of the fixed closing plate 602 in the filter cartridge easily detachable fixing assembly 6.

[0040] The fixed closing plate 602 is inserted into the top opening 601 formed at the top of the external filter cartridge 2. The side of the fixed closing plate 602 is elastically abutted by the fixing spring 609 on the connecting plug rod 607, pushing the end of the connecting plug rod 607 to be inserted into the side slot 604, thereby plugging and fixing between the fixed closing plate 602 and the external filter cartridge 2, making it more convenient for the user to take out and replace the polygonal filter element 1 from the external filter cartridge 2, and facilitating the user to replace the polygonal filter element 1 in the later stage.
