In this embodiment, the lower end of the water washing pipe 4 is located in the water tank 2, and the upper end of the water washing pipe 4 is located above the water tank 2.

[0030] Compared with the prior art, the chicken manure fermentation device provided by the utility model has water in the water tank 2 and the liquid level is higher than the lower end of the water washing pipe 4. The gas generated during the fermentation of chicken manure in the cylinder 1 enters the cylinder 1 along the exhaust pipe 3 and the air inlet 521, and enters the water tank 2 along the air outlet 522 and the water washing pipe 4 after being filtered by the filter material 51 in the cylinder 1. After being washed with water in the water tank 2, it is discharged from the exhaust hole 21. In this way, the gas generated by the fermentation of chicken manure will be filtered by the filter material 51 before being washed with water, thereby avoiding the problem that the purification effect of a single water washing on the gas generated by the fermentation of chicken manure is limited.

[0031] In some embodiments, the feature filtering component may be used as follows: Figure 4 and Figure 5 See the structure shown. Figure 4 and Figure 5, the filter assembly also includes a first filter screen 53 and a second filter screen 54.

Among them, the filter material 51 is activated carbon. When the gas enters the filter cartridge 52 through the air inlet 521, the first filter screen 53 will filter out the dust in the gas, thereby further improving the purification effect of the gas. The first filter screen 53 and the second filter screen 54 can prevent the filter material 51 from leaking from the air inlet 521 and the air outlet 522. Activated carbon can efficiently adsorb harmful gases.

[0032] In some embodiments, see Figures 3 to 5 The filter cartridge 52 is vertically arranged, the air inlet 521 and the air outlet 522 are respectively located on the top wall and the bottom wall of the filter cartridge 52, and the filter assembly further includes a bottom pipe 55. The bottom pipe 55 is slidably sleeved outside the upper end of the water washing pipe 4, and the upper end of the bottom pipe 55 is fixedly connected to the bottom wall of the filter cartridge 52 and is coaxially arranged with the air outlet 522. Through the cooperation of the bottom pipe 55 and the water washing pipe 4, the filter assembly can be connected to the water washing pipe 4, and the air outlet 522 is in a communicating state with the water washing pipe 4.

[0033] In some embodiments, the feature filtering component may be used as follows: Figures 2 to 5 See the structure shown. Figures 2 to 5 The filter assembly also includes a vertically arranged top pipe 56, the lower end of which is fixedly connected to the top wall of the filter cartridge 52 and coaxially arranged with the air inlet 521, the exhaust pipe 3 has a vertically arranged vertical section 31, and the vertical section 31 is located above the top pipe 56, and the chicken manure fermentation device also includes a butt pipe 6 and a connecting hose 7.

The gas in the vertical section 31 enters the air inlet 521 through the connecting hose 7, the butt pipe 6 and the top pipe 56. When the filter assembly is used for a period of time, the filtering effect will decrease, at this time, the butt pipe 6 is slid out of the top pipe 56, and then the bottom pipe 55 is slid out of the washing pipe 4, so as to remove the used filter assembly, and then a new filter assembly can be installed. When installing a new filter assembly, first slide the bottom pipe 55 onto the water washing pipe 4 , limit the filter assembly by the water washing pipe 4 , and then insert the butt pipe 6 into the top pipe 56 .

[0034] In some embodiments, see Figure 2 , Figure 3 and Figure 6, the chicken manure fermentation device also includes a fixed pipe 8, a fixed shaft 9, a fixing member 10 and a connecting bolt 110.
