[0018] Example 1

[0019] like Figures 1-5 As shown in the figure, the biofilter device proposed in this embodiment is a low-energy-consumption biofilter that is easy to replace and has high-efficiency deodorization, including a filter box 1, a packing box 2, a first partition 14, a pusher plate 16 and an automatic discharge device.

[0020] The filter box 1 has an opening on one side, and a sealing plate 7 is rotatably installed on the filter box 1 near the opening; the first partition 14 is horizontally arranged inside the filter box 1, and the first partition 14 has a rectangular hole, and a mesh 13 is installed inside the rectangular hole.

[0021] The stuffing box 2 is slidably disposed on the upper end of the filter box 1. Multiple rollers 3 are installed at the bottom end of the stuffing box 2. A power assembly for driving the movement of the stuffing box 2 is installed on the filter box 1. The power assembly includes a servo motor 81 and a threaded rod 82. The servo motor 81 is installed on the filter box 1, and the threaded rod 82 is connected to the output shaft of the servo motor 81. A connecting slide plate 9 is connected to the stuffing box 2. The connecting slide plate 9 is slidably disposed on the filter box 1 and threadedly connected to the threaded rod 82.

[0022] The automatic discharge device includes a circular housing 4, a damping shaft 5, a rack 18, a ratchet mechanism, and multiple rotating plates 6. The circular housing 4 is located below the stuffing box 2. An upper connecting housing 41 connects the circular housing 4 to the stuffing box 2, and a lower connecting housing 42 connects the bottom of the circular housing 4. The damping shaft 5 is rotatably mounted at the center of the circular housing 4. Multiple rotating plates 6 are mounted on the damping shaft 5 in a circular array. The rack 18 is connected to the inner wall of the filter box 1. The ratchet mechanism includes a ratchet 21, a rotating ring 22, a toothed ring 23, a pawl 24, and a spring 25. The ratchet 21 is connected to the outer end of the damping shaft 5. The rotating ring 22 is located outside the ratchet 21 and is rotatably mounted on the circular housing 4. The toothed ring 23 is fixed to the outer circumference of the rotating ring 22. An installation groove is provided on the rotating ring 22. The end of the pawl 24 is slidably mounted in the installation groove. The spring 25 is located in the installation groove. The push plate 16 is movably mounted on the upper end of the first partition 14. An inclined plate 17 is obliquely connected between the push plate 16 and the lower connecting housing 42.

[0023] A microcontroller 10 is installed on the filter box 1, and the microcontroller 10 is electrically connected to the servo motor 81.

[0024] A push rod 26 is connected to the push plate 16. When the push plate 16 moves to the open position, the push rod 26 can push the sealing plate 7 open, so that there is a gap between the sealing plate 7 and the push plate 16, thus preventing waste packing from being stuck between the sealing plate 7 and the push plate 16.

[0025] In this embodiment, when replacing the solid packing at the upper end of the first partition 14, a power assembly drives the stuffing box 2 to move towards the opening side. The movement of the stuffing box 2 drives the push plate 16 to move. During this process, the push plate 16 pushes the packing on the first partition 14 to move towards the opening side. At the same time, the toothed ring 23 rolls on the rack 18. At this time, the rotating ring 22 rotates counterclockwise, while the ratchet 21 and the damping shaft 5 do not rotate, so that the packing inside the stuffing box 2 will not leak out. As the push plate 16 continues to move, the packing pushes the sealing plate 7 to rotate and open, and the waste packing inside is discharged through the opening. When the push plate 16 moves to the limit position... Afterwards, the waste packing is basically discharged. When the drive packing box 2 moves back, since all the waste is discharged, the sealing plate 7 closes the opening under the action of gravity. After the sealing plate 7 is closed, the toothed ring 23 begins to contact the rack 18. At this time, the rotating ring 22 rotates clockwise, which in turn drives the damping shaft 5 to rotate. The rotation of the damping shaft 5 then drives multiple rotating plates 6 to rotate. At this time, the new packing inside the packing box 2 is discharged into the upper end of the partition 13 through the upper connecting shell 41, the circular shell 4, and the lower connecting shell 42. As the packing box 2 continues to move, the packing eventually fills the upper end of the entire first partition 14. This realizes the function of automatic packing replacement.

The input end of the pump 19 is connected to the bottom of the inner cavity of the absorbent storage chamber 101, and its output end is connected to the nozzle 20.

[0028] In the embodiment, it is necessary to supplement that the upper end of the absorption liquid storage cavity 101 is communicated with an air inlet pipe 12, the odor enters into the inside of the absorption liquid storage cavity 101 through the air inlet pipe 12, at the same time, the pump 19 is started to work, the pump 19 transports the absorption liquid in the absorption liquid storage cavity 101 to the spray head 20, the spray head 20 can adopt an atomizing spray head, the atomized absorption liquid is fully mixed with the odor, and the pretreatment of the odor is realized; then the odor enters into the secondary absorption cavity 102 through the communicating pipe 11, and finally flows into the filler, and the secondary treatment of the odor is realized.
