[0002] In the production process of a farm, in order to reduce energy consumption and energy output, the farm's dressings, livestock excrement, etc. can usually be fermented to produce biogas and fertilizer. However, since these dressings and livestock excrement are mostly in a solid-liquid mixture state, current fermentation equipment usually directly loads these solid-liquid mixtures into a fermentation kettle for reaction, resulting in excessive solid matter in the biogas slurry and a large amount of liquid in the biogas residue, which reduces the output and quality of solid organic fertilizer, and at the same time increases the discharge of biogas slurry and reduces the reflux ratio of biogas slurry. Therefore, those skilled in the art hereby propose a technical solution for an integrated device for separating, fermenting and producing fertilizer from biogas residue and biogas slurry in a farm.

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0029] like Figures 1 to 4 As shown, the utility model provides an integrated device for separating, fermenting and making fertilizer from sludge and liquid biogas in a farm, comprising a sludge fermentation tank 1 located on the left, a liquid biogas fermentation tank 2 located on the right side of the sludge fermentation tank 1, and a solid-liquid separation mechanism 3 connected to the sludge fermentation tank 1 and the liquid biogas fermentation tank 2 and located above them.

[0030] Specifically, the sludge fermentation kettle 1 of this embodiment includes a kettle body 11, a sludge outlet 12 passing through and fixed on the left side of the kettle body 11, and a sludge feed pipe 14 passing through and fixed on the right side wall of the kettle body 11. The kettle body 11 is buried in the soil, and an exhaust port 13 is installed on the top surface of the kettle body 11.

[0031] The biogas fermentation tank 2 includes a tank body 21, a biogas feed pipe 22 passing through and fixed on the left side of the tank body 21, and a biogas outlet 24 passing through and fixed on the right side of the tank body 21. The tank body 21 is buried in the soil, and a vent port 23 is installed on the top side wall of the tank body 21.

[0032] The solid-liquid separation mechanism 3 comprises a circular tank 31, a drive motor 37 mounted on the left sidewall of the tank 31, and an auger 34 that rotates within the interior of the tank 31. A filter plate 35 is embedded in the right section of the bottom surface of the tank 31, and a liquid sump 36 is fixed to the bottom surface of the filter plate 35. A feed pipe 33 is installed through the right side of the top surface of the tank 31, with one end of the feed pipe 33 located within the interior of the tank 31 flush with the inner sidewall of the tank 31. A feed port 32 is defined in the right section of the bottom surface of the tank 31, and the filter plate 35 is embedded within the feed port 32.

[0033] More specifically, a circular hole for the sludge feed pipe 14 to pass through is opened on the left side of the bottom surface of the round tank 31, and the circular hole is connected to the top port of the sludge feed pipe 14, and the bottom surface of the liquid storage tank 36 is connected to the top port of the biogas feed pipe 22.

[0036] The integrated device for separating, fermenting and producing fertilizer from biogas residue and liquid in a farm of the present invention first feeds the waste from the farm into the interior of a circular tank 31 through a feeding pipe 33, then drives the auger 34 to rotate via a drive motor 37. As the auger 34 transports the waste, the liquid flows into the liquid sump 36 along the feed port 32 and the filter plate 35, and enters the interior of the tank body 21 under the guidance of the biogas liquid feed pipe 22. The solids are pushed by the auger 34 to the left side of the inner cavity of the circular tank 31 and enter the interior of the kettle body 11 through the biogas residue feed pipe 14. After the interiors of the kettle body 11 and the tank body 21 are both filled with fermentation pharmaceutical adjuvants, the soil landfill wrapping causes the interior temperatures of the kettle body 11 and the tank body 21 to be higher, thereby naturally fermenting and producing fertilizer. The solid fertilizer inside the kettle body 11 is taken out through the biogas residue outlet 12, and the liquid fertilizer inside the tank body 21 is taken out through the biogas liquid outlet 24.
