[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0032] like Figures 1-8 As shown, a filler frame includes a frame body and a plurality of filler curtains 1, wherein the frame body includes an upper mounting frame 2 and a lower mounting frame 3, and a support rod 4 located between the upper mounting frame 2 and the lower mounting frame 3, and both the upper mounting frame 2 and the lower mounting frame 3 are provided with a plurality of mounting rods 5.

[0033] Meanwhile, the two ends of the packing curtain 1 are respectively set on the mounting rod 5 of the upper mounting frame 2 and the mounting rod 5 of the lower mounting frame 3. The packing curtain 1 includes two connecting strips 11 and several packings 12. The ends of the several packings 12 are connected by the connecting strips 11, and the connecting strips 11 are connected to the mounting rods 5.

[0034] Therefore, in actual use, several fillers 12 are connected into a filler curtain 1 by the connecting belt 11, and then the filler curtain 1 is installed on the frame. Compared with installing fillers one by one, the installation of the filler curtain 1 is more convenient. Simply put, it is better to process the fillers in advance, so that the installation is easier and the time is shortened.

[0035] Secondly, hooks 6 are provided at both ends of the upper mounting frame 2, and the hooks 6 can be used with a crane via ropes. Therefore, in actual use, the hooks 6 allow the packing frame to be used with the crane via ropes, so the entire packing frame can be assembled outside, and then the entire packing frame can be lifted by the crane and placed in the pool. When maintenance or replacement is needed, it can be lifted from the pool and placed on the ground for operation, so there is no need to discharge sewage.

[0036] Furthermore, in order to better coordinate the packing frame with the crane and to make the packing frame more securely lifted, hooks 6 are provided in the middle of both sides of the upper mounting frame 2, and these two sides are relatively long.

[0037] like Figures 2-4 As shown, the structure of the filler 12 is as follows: First, the filler 12 is a braided filler woven from a central rope and a flocculent part. The central rope is a polypropylene rope, and the flocculent part is located outside the central rope. The flocculent part is woven from polyester filaments and polyester monofilaments.

[0038] Therefore, in practical use, due to the use of braided filler and its high density, film formation efficiency is faster and biochemical properties are better. Polypropylene rope is made of polypropylene fiber, which is a synthetic fiber made from propylene, a byproduct of petroleum refining. Polyester filament is the commercial name for polyester fiber in China; its characteristics include resistance to chemicals and frequent washing, reducing fading and discoloration of clothing. Polyester monofilament is a single fine filament made of polyester fiber, commonly used in various industrial and civilian fields. Polyester monofilament has high strength, good elasticity and abrasion resistance, and good lightfastness, but poor moisture absorption and dyeability.

[0039] Furthermore, the ends of the packing material 12 are sewn onto the connecting strip 11, and the distance between two adjacent packing materials 12 located in the same packing curtain 1 is the same, so the distribution is more uniform, which makes it easier to treat sewage.

[0040] like Figure 4The connecting strip 11 shown has connecting ropes at both ends for connecting to the mounting rod 5, and at least one connecting rope is evenly distributed in the middle of the connecting strip 11 for connecting to the mounting rod 5. Therefore, in actual use, the connection is made by connecting ropes, and the even distribution in the middle makes the installation of the stuffing curtain 1 more stable and ensures that the connecting strip 11 fits snugly with the mounting rod 5.

[0041] Meanwhile, the distance between two adjacent mounting rods 5 is the same, so the distribution is relatively uniform, which makes it easier to treat sewage.

[0042] like Figures 1-8 As shown, the connections between the various components of the frame and between the frame and other components can be varied, such as welding or other methods.

[0043] During welding, the hook 6 at the end can be aligned with the center line of the support rod 4. Other connection methods are as follows:

[0044] like Figure 5 and Figure 6 As shown, the structure between the hook 6 and the upper mounting bracket 2 is as follows: First, the upper mounting bracket 2 has a mounting groove 1 and a mounting component 7 is provided. The mounting component 7 includes a base plate 71 and a mounting post 72 provided on the base plate 71. The base plate 71 and the upper mounting bracket 2 are connected by fasteners. The middle part of the mounting post 72 and the middle part of the base plate 71 are respectively provided with mounting hole 1 721 and mounting hole 2 corresponding to mounting groove 1. The inner wall of the top of mounting hole 1 721 is provided with a protrusion 722.

[0045] Meanwhile, the hook 6 includes a mounting part 61 and a hook 62 disposed on the mounting part 61. The diameter of the mounting part 61 is larger than the diameter of the hook 62. The bottom of the mounting part 61 is located in the mounting groove and is connected to the upper mounting bracket 2 by fasteners. The top of the mounting part 61 abuts against the protrusion 722.

[0046] The fasteners can be screws. Therefore, in actual use, the bottom of the mounting part 61 is first placed in the mounting groove, and then the mounting part 61 is connected to the upper mounting bracket 2 using fasteners. Next, the mounting part 7 is sleeved on the outside of the hook 6 and moved along the hook 6 until the top of the mounting part 61 abuts against the protrusion 722. Then, the base plate 71 is connected to the upper mounting bracket 2 using fasteners. That is, the installation and limiting are carried out at two points to ensure the stability of the installation.

[0047] like Figure 7 As shown, the structure between the mounting rod 5 and the upper mounting bracket 2 is as follows: First, the upper mounting bracket 2 has a second mounting groove 21 and a mounting plate 8. The mounting plate 8 has a third mounting groove 81 corresponding to the second mounting groove 21. The mounting rod 5 is located between the second mounting groove 21 and the third mounting groove 81. The mounting plate 8 and the upper mounting bracket 2 are connected by fasteners.

[0048] The fasteners can be screws, and the connection between the mounting rod 5 and the upper mounting bracket 2 is at the end. Therefore, in actual use, the mounting rod 5 is first placed in the second mounting groove 21, and then the mounting plate 8 is placed over the mounting rod 5, so that the mounting rod 5 is located between the second mounting groove 21 and the third mounting groove 81, and the mounting plate 8 is connected to the upper mounting bracket 2 using fasteners. The structure between the mounting rod 5 and the lower mounting bracket 3 can also adopt the above-described mounting structure.

[0049] like Figure 8 As shown, the structure between the support rod 4 and the upper mounting bracket 2 is as follows: First, the upper mounting bracket 2 has a mounting groove 4, and a boss 22 is provided in the middle of the mounting groove 4. The top of the support rod 4 has a mounting groove 5 41, and the top of the support rod 4 is located in the mounting groove 4. The boss 22 is located in the mounting groove 5 41. The two outward sides of the support rod 4 are connected to the upper mounting bracket 2 by fasteners.

[0050] The fasteners can be screws. Therefore, in actual use, the top of the support rod 4 is first placed in the mounting groove 4, at which time the boss 22 is also placed in the mounting groove 5 41. Then, fasteners are used to connect the two outward sides of the support rod 4 to the upper mounting bracket 2 respectively. That is, the connection method of first plugging and then tightening is adopted to ensure the stability of the installation. Both sides of the support rod 4 are tightened, which can further ensure the stability of the installation.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
