[0018] Example 1:

[0019] like Figures 1-5As shown, this utility model provides a conveniently assembled filter with partitions, including a housing 1. A filter element 2 is fixedly installed inside the housing 1. An assembly port 3 is provided at the top of the housing 1, through which the filter element 2 is fixedly installed inside the housing 1. A cover plate 4 is fixedly fitted onto the assembly port 3. A first fixing frame 5 and a second fixing frame 6 are fixedly sleeved on the outside of the filter element 2. Both the first fixing frame 5 and the second fixing frame 6 include a first C-shaped frame 7 and a second C-shaped frame 8. The first C-shaped frame 7 has a sliding sleeve section 9, and the second C-shaped frame 8 has a slide rail section 10. The sliding sleeve section 9 has a screw hole 11, and a fastening bolt 12 is fixedly installed in the screw hole 11. A first connecting plate 13 and a second connecting plate 14 are fixedly installed between the first fixing frame 5 and the second fixing frame 6. A carrying rope 15 is fixedly connected between the first connecting plate 13 and the second connecting plate 14, and a handle 16 is fixedly connected to the carrying rope 15. The outer shell 1 has a notch 17 located at the assembly port 3, and the cover plate 4 has a protrusion 18 around its periphery, with the protrusion 18 fixedly fitted into the notch 17.

[0020] Through the above technical solution, the filter element 2 of this utility model is fixedly sleeved with a first fixing frame 5 and a second fixing frame 6 on the outside. The filter plate of the filter element 2 is fixed by the first fixing frame 5 and the second fixing frame 6. The top of the outer shell 1 is provided with an assembly port 3. The filter element 2 is fixedly installed inside the outer shell 1 through the assembly port 3. Then, the cover plate 4 is closed and fixed to the assembly port 3, which quickly completes the assembly of the partition filter, simplifies the complicated assembly process of the partition filter, and improves production efficiency.

[0021] Example 2:

[0022] like Figures 1-5As shown, this embodiment provides a diaphragm filter that is easy to assemble. The filter includes a housing 1 and a filter element 2. The housing 1 has a cylindrical structure with a circular mounting opening 3 at the top. The filter element 2 is fixedly installed inside the housing 1 through the mounting opening 3. A circular cover plate 4 is fixedly fitted onto the mounting opening 3, and the cover plate 4 is connected to the housing 1 by screws. A first fixing frame 5 and a second fixing frame 6 are fixedly sleeved on the outside of the filter element 2. The first fixing frame 5 and the second fixing frame 6 have the same structure, both consisting of a first C-shaped frame 7 and a second C-shaped frame 8. The first C-shaped frame 7 has a sliding sleeve section 9. The second C-shaped frame 8 has a slide rail section 10 that mates with the sliding sleeve section 9. The sliding sleeve section 9 has multiple screw holes 11, and fastening bolts 12 are fixedly installed in the screw holes 11. During assembly, the filter plate of filter element 2 is first placed into the first fixing frame 5 and the second fixing frame 6. Then, the sliding sleeve section 9 and the slide rail section 10 are fixed with fastening bolts 12, thus firmly fixing the filter plate of filter element 2 within the fixing frame, forming filter element 2. Next, the entire filter element 2 assembly is inserted into the housing 1 through the assembly port 3 at the top of the housing 1. After adjusting the position, the cover plate 4 is closed to complete the assembly. This design makes the installation of filter element 2 simple and quick, greatly improving assembly efficiency. The use of fastening bolts 12 ensures the firmness of filter element 2 installation. The assembly port 3 at the top of the housing 1 allows the entire filter element 2 assembly to be easily inserted from the top, avoiding the difficulties that may arise from side installation. The cover plate 4 not only provides a sealing function but also facilitates subsequent maintenance and replacement. This structural design fully considers the convenience of assembly and maintenance while ensuring the performance and stability of the filter. By simplifying the assembly process, errors that may occur during assembly are reduced, improving product reliability. In addition, this design facilitates mass production, significantly improving production efficiency and reducing production costs.

[0023] Example 3:

[0024] like Figures 1-5As shown, this embodiment further improves the fixing frame structure. A first connecting plate 13 and a second connecting plate 14 are fixedly installed between the first fixing frame 5 and the second fixing frame 6. The first connecting plate 13 is connected to the upper end of the first fixing frame 5 and the second fixing frame 6 by bolts, and the second connecting plate 14 is connected to the lower end of the first fixing frame 5 and the second fixing frame 6 by bolts. This design connects two independent fixing frames into a whole, further enhancing the stability of the structure. During assembly, the filter plate of the filter element 2 is first placed into the first fixing frame 5 and the second fixing frame 6, and then the first connecting plate 13 and the second connecting plate 14 are installed to connect the two fixing frames into a whole. This whole structure is then placed into the housing 1 through the assembly port 3 at the top of the housing 1. The use of connecting plates not only enhances the structural strength but also simplifies the installation process. Operators can assemble the filter element 2 and the fixing frame into a complete unit and then place it into the housing 1 at once, without having to install each component separately. This method reduces installation steps and improves efficiency. At the same time, the presence of connecting plates makes the entire filter element 2 assembly a stable whole, reducing the possible shaking or displacement of the filter element 2 during use. This not only improves filtration efficiency but also extends the lifespan of the equipment. Furthermore, when filter element 2 needs to be replaced or cleaned, the entire assembly can be easily removed from the housing 1, greatly simplifying maintenance.

[0025] Example 4:

[0026] like Figures 1-5As shown, based on Embodiment 3, this embodiment further optimizes the ease of filter assembly. A carrying rope 15 is fixedly connected between the first connecting plate 13 and the second connecting plate 14, and a handle 16 is fixedly connected to the carrying rope 15. The carrying rope 15 is made of wear-resistant nylon material, with a moderate length, and can easily wrap around the entire filter element 2 assembly. The handle 16 is an ergonomically designed plastic grip with a non-slip texture. The two ends of the carrying rope 15 are respectively connected to the first connecting plate 13 and the second connecting plate 14 through metal rings, and the connection is reinforced to ensure safe use. During assembly, the operator can easily move and install the entire filter element 2 assembly using the carrying rope 15 and the handle 16. First, the filter plates of the filter element 2 are installed in the first fixing frame 5 and the second fixing frame 6 and fixed with fastening bolts 12. Then, the first connecting plate 13 and the second connecting plate 14 are installed to form a complete assembly. Finally, by grasping the handle 16, the entire assembly is placed into the housing 1 through the assembly port 3 on the top of the housing 1. This design greatly simplifies the installation process and reduces the burden on operators. Especially for larger filters, the carrying rope 15 and handle 16 make handling and installation easier and safer. This design also demonstrates significant advantages in routine maintenance. When cleaning or replacing the filter element 2 is required, simply open the cover 4 and grasp the handle 16 to easily remove the entire filter element 2 assembly from the housing 1. This not only saves time but also reduces operational difficulty, making maintenance work simpler and more efficient.

[0027] Example 5:

[0028] like Figures 1-5As shown, the outer shell 1 of this utility model has a recess 17 structure at the assembly port 3, and a corresponding protrusion 18 structure is provided around the periphery of the cover plate 4. The outer shell 1 is made of metal and is cylindrical in shape, with the top opening forming the assembly port 3. Multiple semi-circular recesses 17 are arranged around the edge of the assembly port 3. The cover plate 4 is also made of metal and its shape matches the assembly port 3. Semi-circular protrusions 18 corresponding to the recesses 17 are evenly distributed around its periphery. The height of the protrusions 18 is the same as the depth of the recesses 17 and slightly smaller than the width of the recesses 17 to ensure smooth insertion. During assembly, after the filter element 2 is placed inside the outer shell 1, the cover plate 4 is placed aligned with the assembly port 3. The cover plate 4 is gently pressed to align the protrusions 18 with the recesses 17, and then the cover plate 4 is pressed tightly with a little force. The protrusions 18 will gradually insert into the recesses 17 until they fit completely. At this time, the cover plate 4 and the outer shell 1 are tightly fitted, forming a good sealing effect. During disassembly, simply lift the edge of the cover plate 4 with a little force to disengage the protrusion 18 from the recess 17, and easily remove the cover plate 4. This interlocking structure design has multiple advantages. First, it simplifies the installation process, allowing the cover plate 4 to be secured without additional fasteners. Second, the interlocking structure increases the contact area, improving sealing performance and preventing air leakage. Third, the interlocking structure enhances the stability of the cover plate 4, reducing the possibility of loosening. Finally, this design facilitates disassembly, making subsequent maintenance and filter element 2 replacement convenient.
