[0027] The embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings:

[0028] Please refer to Figures 1-7 , an embodiment provided by the present utility model: a domestic sewage composite filler treatment device, including a sewage treatment tank 10, a filler frame 20 and a composite filler carrier plate 21. The two sides of the sewage treatment tank 10 are communicated with a water inlet pipe 11. In the inner cavity of the sewage treatment tank 10, fixed sliding plates 12 are respectively fixedly installed on the front and rear side walls. The front and rear end faces of the filler frame 20 are slidably connected to the fixed sliding plates 12. The left and right sides of the filler frame 20 are respectively densely provided with water passing round holes. At the same time, the bottom of the filler frame 20 is a net structure, which can effectively intercept some aged and fallen-off fillers. At the bottom of the inner cavity of the filler frame 20, two sliding platforms 24 are fixedly installed. The two sliding platforms 24 are symmetrically distributed front and rear with respect to the center line of the filler frame 20. A plurality of mounting blocks 25 are respectively slidably installed on each sliding platform 24. The upper end face of the sliding platform 24 is provided with a convex portion. The chute opening at the bottom of the mounting block 25 is embedded in the convex portion on the upper end face of the sliding platform 24. The upper end face of the mounting block 25 is provided with a missing cavity 26. Clamping chutes 27 are respectively arranged on the left and right side walls of the missing cavity 26. A clamping plate 28 is respectively slidably installed in each clamping chute 27. A convex column 29 is respectively fixedly installed on the upper end face of each clamping plate 28. An inner groove opening is arranged in the missing cavity 26. A hook-shaped plate 32 is installed in the inner groove opening. The bottom of the hook-shaped plate 32 is rotatably connected to the inner groove opening through a short shaft. Two trapezoidal sliding plates 30 are slidably connected to the upper end face of the mounting block 25. A cylindrical rod 31 is fixedly connected between the two trapezoidal sliding plates 30. The cylindrical rod 31 passes through a strip-shaped hole 33 arranged on the hook-shaped plate 32;

[0029] The bottom of the composite filler carrier plate 21 is embedded in the missing cavity 26, thereby pressing the bottom end of the hook-shaped plate 32. The upper end portion of the hook-shaped plate 32 warps inward, thereby driving the two trapezoidal sliding plates 30 to slide towards the direction of the composite filler carrier plate 21, so that the hypotenuse of the trapezoidal sliding plate 30 slides against the convex column 29, driving the convex column 29 to slide towards the direction of the composite filler carrier plate 21, thereby driving the two clamping plates 28 to clamp the composite filler carrier plate 21 and fix the composite filler carrier plate 21. An elastic head is arranged on the clamping plate 28, and the elastic head is used to contact and press the composite filler carrier plate 21, thereby effectively ensuring the stability of the composite filler carrier plate 21. During the long-term sewage purification process, it can effectively withstand the impact of water flow. At the same time, the distance between two adjacent composite filler carrier plates 21 can be adjusted at any time according to the specific requirements of sewage purification, and it is very convenient to use.

[0030] It should be noted that, in order to further facilitate people to adjust the distance between the composite filler carrier plates 21, sliders 22 are respectively and slidably installed at the edges of the front and rear side walls on the upper end surface of the filler frame body 20 in this embodiment. A limiting rod 23 is fixedly connected between the two sliders 22. The composite filler carrier plate 21 passes through between the two limiting rods 23. The upper ends of the two limiting rods 23 on both sides are used to limit the composite filler carrier plate 21. At the same time, when adjusting the distance between the composite filler carrier plates 21, only by sliding the sliders 22 on both sides can the composite filler carrier plate 21 be driven to move horizontally. Moreover, it is also convenient to push aside the composite filler carrier plate 21 to observe one of the composite filler carrier plates 21, so as to facilitate knowing whether it is necessary to replace the composite filler carrier plate 21, without having to pull out the whole composite filler carrier plate 21 for observation.

[0031] It is worth mentioning that, in this embodiment, a bracket 13 is fixedly installed on the upper end surface of the above-mentioned fixed slide plate 12. An elevator 14 is fixedly installed on the upper end surface of the bracket 13. The output end of the elevator 14 is fixedly connected with a connecting disc 15. A steel wire rope 16 is fixedly connected between the connecting disc 15 and the filler frame body 20. When the amount of sewage is relatively small, the elevator 14 can be controlled to move downward, so that the filler frame body 20 slides downward to a suitable water level. It is also possible to control the elevator 14 to drive the filler frame body 20 to be pulled out upward, which is convenient for replacing the composite filler carrier plate 21.

[0032] During the specific implementation, the composite filler carrier plate 21 is first passed through between the two limit rods 23, and the bottom is embedded in the notch 26, thereby pressing the bottom end of the hook plate 32, and the upper end of the hook plate 32 is tilted inward, thereby driving the two trapezoidal slides 30 to slide in the direction of the composite filler carrier plate 21, so that the hypotenuse of the trapezoidal slide 30 slides against the protruding column 29, driving the protruding column 29 to slide in the direction of the composite filler carrier plate 21, thereby driving the two clamping plates 28 to clamp the composite filler carrier plate 21 and fix the composite filler carrier plate 21. The clamping plate 28 is provided with an elastic head, which is used to contact and press the composite filler carrier plate 21, thereby effectively ensuring the stability of the composite filler carrier plate 21 and purifying the sewage for a long time. During the water process, it can effectively withstand the impact of water flow, so that the microorganisms on the biofilm on the composite filler carrier plate 21 can degrade the organic matter in the sewage, and can also remove part of the ammonia nitrogen and phosphorus. At the same time, the distance between two adjacent composite filler carrier plates 21 can be adjusted at any time according to the specific needs of sewage purification. It is only necessary to slide the sliders 22 on both sides to drive the composite filler carrier plate 21 to move horizontally, and it is also convenient to push the composite filler carrier plate 21 apart and observe one of the composite filler carrier plates 21, so as to know whether the composite filler carrier plate 21 needs to be replaced. There is no need to pull out the entire composite filler carrier plate 21 for observation. It is very convenient to use and has high stability for the composite filler carrier plate 21.

[0033] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
