Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to an aeration biological filler. Background Technique

[0002] Biological fillers are microbial carriers applied in the MBBR process, mainly providing a suitable growth environment for microorganisms. MBBR fillers are a new type of biological active carrier. They adopt a scientific formula and incorporate a variety of trace elements beneficial to the rapid attachment and growth of microorganisms in polymer materials according to different sewage properties.

[0003] Traditional MBBR biological fillers are mainly manufactured by an integral injection molding method. This results in the inability to effectively clean the ineffective microorganisms inside the fillers during the recycling process. Consequently, when the fillers are reused, new effective microorganisms cannot reattach to the inside of the fillers, reducing the sewage treatment effect of the fillers. Moreover, when the fillers are put into sewage, the fillers will flip in the sewage with the bubbles generated by the aeration device, and the fillers will collide with adjacent fillers during the flipping process, causing the microorganisms on the fillers to fall off or the fillers to break, thus affecting the sewage treatment effect of the fillers. Content of the Utility Model

[0004] The utility model provides an aeration biological filler to solve at least some of the above technical problems.

[0005] To achieve the above object, the technical scheme adopted by the utility model is as follows:

[0011] Further, the connecting mechanism includes an inner ring plate provided on the limiting rotating shaft and an outer ring plate coaxially distributed with the inner ring plate; the end of the partition plate is connected between the inner ring plate and the outer ring plate.

[0012] Further, insertion slots adapted to the film hanging mechanism are provided on the outer wall of the inner ring plate and the inner wall of the outer ring plate, and both ends of the film hanging mechanism are respectively inserted into the corresponding insertion slots.

[0013] Further, a mounting seat is provided on the hemispherical shell, and a shaft hole is provided on the mounting seat; the limiting rotating shaft includes a limiting shaft and two connecting shafts respectively provided at the ends of the limiting shaft for rotatably inserting into the shaft hole; the inner ring plate is sleeved on the connecting shaft, and a limiting step for limiting the inner ring plate is formed between the connecting shaft and the limiting shaft.

[0034] Embodiment 1

[0035] As Figure 1-11 shown, an aeration biological filler provided by the present utility model includes a filler support 1, two hemispherical shells 2 respectively threadedly and detachably connected to both ends of the filler support 1, and a film hanging support 3 rotatably installed between the two hemispherical shells 2 and located inside the filler support 1; a film hanging mechanism 4 for microbial attachment is provided on the film hanging support 3, and a limiting ring plate 5 is provided between the filler support 1 and the hemispherical shell 2.

[0036] In the present utility model, the filler support 1 and the hemispherical shell 2 are connected in a threadedly detachable manner, so that it is convenient to take out the film hanging support 3 and the film hanging mechanism 4 inside the filler support 1, thereby facilitating the cleaning of ineffective microorganisms on the film hanging mechanism 4. At the same time, when the film hanging support 3 and the film hanging mechanism 4 are put into sewage, even if the film hanging support 3 and the film hanging mechanism 4 are collided, the filler support 1 and the hemispherical shell 2 absorb the impact force, so as to prevent the microorganisms on the film hanging mechanism 4 from falling off. At the same time, the limiting ring plate 5 is installed between the filler support 1 and the hemispherical shell 2, so that the limiting ring plate 5 is in contact with the ends of the film hanging support 3 and the film hanging mechanism 4, thereby preventing the film hanging support 3 and the film hanging mechanism 4 from sliding out of the filler support 1.

[0037] Both the filler support 1 and the hemispherical shell 2 of the present utility model are of a hollow structure. The hollow structure can facilitate the sewage to enter the filler support 1 and the hemispherical shell 2, thereby facilitating the formation of a biofilm by the microorganisms on the film hanging mechanism 4. Both the filler support 1 and the hemispherical shell 2 of the present utility model are made of plastic.

[0038] Example 2

[0039] As Figure 1-11 shown, an aeration biological filler provided by the utility model includes a filler support 1, two hemispherical shells 2 respectively threadedly and detachably connected to both ends of the filler support 1, and a film hanging support 3 rotatably installed between the two hemispherical shells 2 and located inside the filler support 1; a film hanging mechanism 4 for microbial attachment is arranged on the film hanging support 3, and a limiting ring plate 5 is arranged between the filler support 1 and the hemispherical shell 2.

Internal threads adapted to the hemispherical shell 2 are arranged on the inner wall of the end of the support shell 6. A circle of limiting convex ribs 21 is arranged at the end of the inner wall of the support shell 6 at the end of the internal threads. The limiting ring plate 5 is located between the limiting convex ribs 21 and the corresponding hemispherical shell 2.

[0041] Based on Example 1, Example 2 gives a more preferable structure of the filler support 1. Specifically, the filler support 1 includes a support shell 6 in a cylindrical hollow structure.

A circle of limiting convex ribs 21 is arranged at the end of the inner wall of the support shell 6 at the end of the internal threads. The limiting ring plate 5 is located between the limiting convex ribs 21 and the corresponding hemispherical shell 2.

[0042] An elastic anti-collision strip 23 is arranged on the outer wall of the support shell 6 of the utility model. The elastic anti-collision strip 23 can effectively absorb the impact force hitting the support shell 6. At the same time, the cylindrical hollow structure allows sewage to pass through, so that the microorganisms on the film hanging mechanism 4 can treat the sewage. Internal threads are arranged on the inner wall of the end of the support shell 6 of the utility model, and external threads adapted to the internal threads are arranged on the hemispherical shell 2. Both ends of the support shell 6 are respectively threadedly connected to the corresponding hemispherical shells 2. At the same time, a circle of limiting convex ribs 21 is arranged at the end of the inner wall of the support shell 6 at the end of the internal threads. The limiting ring plate 5 is located between the limiting convex ribs 21 and the corresponding hemispherical shell 2. When the hemispherical shell 2 is threadedly connected to the support shell 6, the end face of the hemispherical shell 2 contacts the limiting ring plate 5, so as to fix the limiting ring plate 5 between the limiting convex ribs 21 and the corresponding hemispherical shell 2, and limit the position of the film hanging mechanism 4 through the limiting ring plate 5, so as to prevent the film hanging mechanism 4 from sliding out of the film hanging support 3.
