[0024] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0025] like Figure 1-4 As shown, the utility model provides a suspended filler structure for an anaerobic tank, comprising a filler frame 10 , an annular baffle 20 , an elastic filler 30 and a fender 40 .

[0026] The filling frame 10 is disposed in the anaerobic tank in a transverse direction and is adapted to the anaerobic tank. The filling frame 10 is provided with an inspection port 11 which penetrates in a longitudinal direction.

[0027] The annular baffle 20 is fixedly installed at the bottom of the inner wall of the inspection opening 11 in the transverse direction, and a receiving chamber 12 is formed between the annular baffle 20 and the inspection opening 11 .

[0028] The elastic filler 30 is disposed in the accommodating chamber 12 and is adapted to the accommodating chamber 12. The elastic filler 30 enables the water-gas biofilm to be fully exchanged, so that the organic matter in the water is efficiently treated.

[0029] The mud guard 40 is arranged on the top of the filling frame 10, the first side of the mud guard 40 is hinged to the filling frame 10, and the second side of the mud guard 40 is detachably connected to the filling frame 10. The mud guard 40 is provided with a through installation opening 41, and a mud guard net 42 is fixedly installed on the inner wall of the installation opening 41, and the mud guard net 42 is used to prevent excessive activated sludge from entering the next process section.

[0030] When the bottom mud is stirred, the suspended elastic filler 30 and the mud retaining net 42 in the present application can isolate the bottom mud from the supernatant, thereby reducing the solid content in the supernatant and preventing the activated sludge from excessively entering the next process stage. In addition, the suspended elastic filler 30 can further increase its water tightness and more stably achieve DO (dissolved oxygen) < 0.2 mg / L, so that the anaerobic tank can achieve the best treatment effect.

[0031] In one embodiment, a threaded hole 13 is formed on the filler frame 10 , and a screw 43 is disposed on the second side of the fender 40 . The threaded end of the screw 43 passes through the fender 40 and then matches with the threaded hole 13 .

[0032] In the use state, the threaded end of the screw 43 is matched with the threaded hole 13, so that the fender 40 is fixed on the packing frame 10, so that the utility model remains stable. When the elastic packing 30 in the accommodating cavity 12 needs to be repaired or replaced, the staff can unscrew the screw 43 and flip up the second side of the fender 40, so that the elastic packing 30 in the accommodating cavity 12 can be repaired or replaced, and the operation is simple.

[0033] In one embodiment, the filling frame 10 is made of PVC material. The PVC material has low water absorption, relatively independent closed bubbles and good integrity, so that it has a certain waterproof performance.

[0034] In one embodiment, fixing ropes 14 are disposed around the filling frame 10 , a first end of the fixing rope 14 is fixedly connected to the filling frame 10 , and a second end of the fixing rope 14 is a free end.

[0035] In the use state, the second end of the fixing rope 14 is fixedly connected to the inner wall of the anaerobic tank. The design of the fixing rope 14 can fix the filling frame 10 on the one hand to prevent the filling frame 10 from floating to sleep; on the other hand, the fixing rope 14 also allows the filling frame 10 to have a certain degree of freedom and can swing up and down in the longitudinal direction, so that the elastic filler 30 is in contact with water more evenly, the fluidity is better, and the purification effect of the elastic filler 30 is improved.

[0036] In one embodiment, a plurality of floating balls 15 are fixedly mounted on the bottom of the filling frame 10 to further increase the buoyancy of the filling frame 10 .

[0037] In one embodiment, the plurality of floating balls 15 are arranged in a U-shaped pattern, so that the buoyancy of the filling frame 10 is more uniform, and the balance of the filling frame 10 is better.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
