[0047] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a stepped filtration device for wastewater treatment that facilitates filter element replacement.

[0048] A stepped filtration device for wastewater treatment with easy filter element replacement includes a base 1 and a filter element 2, a filter box 3 disposed on the base 1 and fixedly connected to the base 1; a mounting base 4 disposed on the base 1 and fixedly connected to the base 1; multiple fixing columns 5 disposed on the mounting base 4 and fixedly connected to the mounting base 4; and two fixing mechanisms disposed on the fixing columns 5 and the mounting base 4 for fixing the filter element 2.

[0049] refer to Figure 1 In a preferred embodiment, the fixing mechanism includes: a connecting part disposed on the mounting base 4 and the fixing post 5 for connecting and fixing the two ends of the filter element 2; and a fixing device disposed on the connecting part for fixing the connecting device.

[0050] refer to Figure 1 and Figure 2 as well as Figure 3 In a preferred embodiment, the connecting part includes: a plurality of first fixing covers 6, which are fixedly disposed on the mounting base 4 and fixedly connected to the mounting base 4; a plurality of fixing plates 7, which are disposed on the fixing post 5 and fixedly connected to the fixing post 5; a plurality of support springs 8, which are disposed on the fixing plate 7 and fixedly connected to the fixing plate 7; a connecting plate 9, which is disposed on the fixing post 5 and used to fix the component; and a plurality of second fixing covers 10, which are disposed on the connecting plate 9 and used to fix the filter element 2.

[0051] In this configuration, the first fixing cover 6 and the second fixing cover 10 are used to make close contact with the filter element 2; the support spring 8 is used to support the connecting plate 9 around its perimeter to maintain the balance of the connecting plate 9; the connecting plate 9 is used to install the fixing knob 13 and place the second fixing cover 10, and the connecting plate 9 is provided with two threaded holes for connecting the connecting plate 9 and the moving part 17 with fixing bolts; the second fixing cover 10 is used to fix the filter element 2 in conjunction with the first fixing cover 6, and the second fixing cover 10 is fixed inside the connecting plate 9 by the fixing knob 13.

[0052] refer to Figure 1 In a preferred embodiment, the fixing device includes: a mounting part disposed on the connecting plate 9 and the filter box 3 for mounting the various components; and a driving part disposed on the mounting part for providing power to the fixing device.

[0053] refer to Figure 4 and Figure 5 In a preferred embodiment, the mounting part includes: two mounting plates 11, which are disposed on the filter box 3 and fixedly connected to the filter box 3; a mounting bracket 12, which is disposed on the filter box 3 and fixedly connected to the filter box 3; and multiple fixing knobs 13, which are disposed on the connecting plate 9 and rotatably connected to the connecting plate 9.

[0054] refer to Figure 1 and Figure 5In a preferred embodiment, the drive unit includes: a drive motor 14, mounted on the mounting frame 12 and fixedly connected to the mounting frame 12; two sprockets 15, each mounted on the output end of the drive motor 14 and the mounting plate 11 respectively, and fixedly connected to the output end of the drive motor 14, with the sprockets 15 rotatably connected to the mounting plate 11; a helical rod 16, mounted on the mounting plate 11 and rotatably connected to the mounting plate 11; and a movable member 17, mounted on the helical rod 16 and threadedly connected to the helical rod 16.

[0055] In this configuration, the moving part 17 is made of aluminum alloy, which is high-strength and rust-resistant. The moving part 17 has threaded holes for fixing bolts to the connecting plate 9. There are two sprockets 15; one is located at the output end of the drive motor 14 and is fixedly connected to it, while the other sprocket 15 is rotatably connected to the mounting plate 11 and the connecting plate 9. The two sprockets 15 are connected by a chain. A screw rod 16 is used to drive the moving part 17 to move up and down. One end of the screw rod 16 is located on the mounting plate 11, and the other end is located on the sprocket 15 rotatably connected to the mounting plate 11 and is fixedly connected to the sprocket 15.

[0056] This device, through a fixing mechanism, can secure the filter element 2 using the first fixing cover 6 and the second fixing cover 10. While the first and second fixing covers 6 and 10 are not fixedly connected to the filter element 2, they are secured solely through tight contact, making replacement more convenient. This fixing mechanism also allows for the collective disassembly and replacement of individual filter elements 2, making filter element replacement more convenient and faster.

[0057] Working principle: When replacing filter element 2, this device starts the drive motors 14 on both sides. The drive motors 14 rotate forward, driving the sprocket 15 to rotate. The rotation of the sprocket 15 drives the screw rod 16 to rotate. The rotation of the screw rod 16 drives the moving part 17 to move on the screw rod 16, allowing the moving part 17 to move away from the base 1. At the same time, the moving part 17 drives the connecting plate 9 to move together. When the connecting plate 9 moves, it drives the second fixing cover 10 to move. The second fixing cover 10 will drive the filter element 2 to detach from the first fixing cover 6. Then the drive motor 14 stops rotating. Then the fixing bolt between the connecting rod and the moving part 17 is removed, and the connecting plate 9 can be removed from the fixing post 5. Then the filter element 2 on the second fixing cover 10 can be replaced. The above steps are for disassembling and replacing the filter element 2 in this device. When replacing the filter element 2 alone, locate the second fixing cover 10 corresponding to the filter element, and then rotate the fixing knob 13 around the second fixing cover 10 to disengage the fixing knob 13 from the second fixing cover 10. After that, by pulling out the second fixing cover 10, the second fixing cover 10 will bring the filter element 2 out with it. Then, the filter element can be replaced.

[0058] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
