[0032] The staff connects the air inlet of the external waste gas treatment equipment with the flying outlet pipe on the sealing cover 2, which makes it easy to treat the waste gas discharged from the fermentation tank 1 through the waste gas treatment equipment.

[0033] The specific structure, specific humidification method, function and connection relationship of the serpentine humidification tube 4 in this application with the sealing cover 2 are the same as the serpentine humidification tube 4 and the sealing cover 2 in the patent application number: 202322189489.9, so they will not be elaborated here.

[0034] A support frame 7 is fixedly mounted on the outer end of the fermentation tank 1 , an oxygen supply mechanism 9 is installed on the lower end of the fermentation tank 1 , and the upper end of the oxygen supply mechanism 9 passes through the lower end of the fermentation tank 1 and extends into the interior of the fermentation tank 1 .

[0035] Oxygen supply to the interior of the fermentation tank 1 can be achieved through the oxygen supply mechanism 9 .

[0036] In this embodiment, Figure 3-4 As shown, the oxygen supply mechanism 9 includes a motor 907, which is fixedly mounted on the lower end surface of the fermentation tank 1 through an L-shaped mounting bracket. The left end of the output shaft of the motor 907 is mechanically linked to a ring-shaped drive plate 901, which is rotatably mounted in the middle of the lower end surface of the fermentation tank 1.

[0037] Multiple mounting cylinders 903 are mounted in a circular array within the annular drive plate 901. The upper ends of the mounting cylinders 903 extend through the lower end of the fermenter 1 and into the interior of the fermenter 1. Multiple ventilation holes 905 are evenly distributed on the outer end surfaces of the mounting cylinders 903, positioned within the fermenter 1. These ventilation holes 905 are fitted with stainless steel filters. The stainless steel filters prevent microbial organic fertilizer from entering the mounting cylinders 903 through the ventilation holes 905, providing isolation and filtration.

[0038] By starting the motor 907, the motor 907 can drive the annular driving plate 901 to rotate, and the rotating annular driving plate 901 can drive the mounting cylinder 903, thereby expanding the oxygen supply range of the vent hole 905, thereby improving the oxygen supply efficiency.

[0039] The mounting cylinder 903 is rotatably connected to the bottom of the fermentation tank 1 through a bearing, and a rubber sealing ring is provided at the connection between the mounting cylinder 903 and the fermentation tank 1 .

[0040] A plurality of stirring rods 904 are fixedly mounted in a circular array on the side end surface of the mounting cylinder 903 and located inside the fermentation tank 1 .

[0041] The rotating mounting cylinder 903 can stir the microbial organic fertilizer through the stirring rod 904, thereby improving the contact efficiency between the microbial organic fertilizer and oxygen and water mist, and further improving the regulation effect of the microbial organic fertilizer.

[0042] A driving gear 906 is fixedly mounted on the upper end of the output shaft of the motor 907 , and an outer gear ring 911 is embedded and fixedly mounted on the outer end surface of the annular driving plate 901 , and the driving gear 906 is meshed with the outer gear ring 911 .

[0043] The motor 907 can drive the driving gear 906 to rotate, and the rotating driving gear 906 can drive the annular driving plate 901 through the outer ring gear 911, thereby realizing mechanical linkage between the motor 907 and the annular driving plate 901.

[0044] An inner gear ring 912 is embedded and fixedly installed inside the annular driving plate 901 , and an installation gear 902 is fixedly sleeved on the bottom of the installation cylinder 903 , and the installation gear 902 is meshed with the inner gear ring 912 .

[0045] The rotating annular driving plate 901 can drive the mounting gear 902 through the inner gear ring 912 , thereby driving the mounting cylinder 903 to rotate, thereby realizing mechanical linkage between the annular driving plate 901 and the mounting cylinder 903 .

[0046] An air intake pipe 910 is fixedly installed in the middle of the lower end surface of the fermentation tank 1, and a connecting pipe 908 is installed at the lower end of multiple mounting cylinders 903 through a connecting shell. The other end of the connecting pipe 908 is connected to the air intake pipe 910, and an air control valve 909 is fixedly installed on the air intake pipe 910 and below the connecting pipe 908. A connecting shell is fixedly sleeved on the bottom of the mounting cylinder 903, and a plurality of first air vents 905 are evenly provided on the inner side wall of the connecting shell. A plurality of second air vents 905 are evenly provided on the mounting cylinder 903 and located on the inner side of the connecting shell. The upper and lower ends of the connecting shell are rotatably connected to the mounting cylinder 903 through bearings, and a sealing rubber ring is provided at the connection between the connecting shell and the mounting cylinder 903. One end of the connecting pipe 908 is fixedly connected to the connecting shell.

[0047] Open the air control valve 909, and the supplemented oxygen can enter the air inlet pipe 910, enter the connecting shell through the connecting pipe 908, and then enter the installation cylinder 903 through the first air vent 905 and the second air vent 905, and finally enter the fermenter 1 through the air vent 905.

[0048] The oxygen concentration sensor 5 and the humidity sensor 8 are both electrically connected to the single chip microcomputer 6 , and the single chip microcomputer 6 is electrically connected to the air control valve 909 , the solenoid valve, and the motor 907 .

[0049] The oxygen concentration sensor 5 and the humidity sensor 8 detect the oxygen concentration and humidity of the fermentation tank 1 in real time and synchronize the detection data to the single-chip microcomputer 6, which is then judged by the single-chip microcomputer 6. When the oxygen concentration is insufficient, the single-chip microcomputer 6 regulates the air valve 909 to open, so that oxygen enters the fermentation tank 1. The oxygen entering the fermentation tank 1 is matched with the mounting cylinder 903 and the vent 905, so that the oxygen can enter the microbial organic fertilizer pile that needs to be fermented, thereby providing sufficient oxygen supply for the microbial strains, which can effectively promote the decomposition of organic matter in the fermentation process and accelerate the reproduction and activity of microorganisms. In addition, the mounting cylinder 903 and the vent 905 can also discharge harmful gases generated during the fermentation of the microbial organic fertilizer. Some organic gases generated during the fermentation of organic fertilizer, such as methane and hydrogen sulfide, can be discharged to ensure the environmental quality of the fermentation process. The ventilation effect of the mounting cylinder 903 and the vent 905 can not only reduce the generation of odor, but also prevent the temperature in the organic fertilizer pile from being too high, thereby avoiding negative effects on the growth of microorganisms.

[0050] When the humidity is insufficient during the fermentation process of organic fertilizer, the single chip microcomputer 6 controls the solenoid valve to open, and water is transmitted through the serpentine humidification tube 4 and finally sprayed out by the atomizing nozzle to humidify the microbial organic fertilizer pile. By controlling conditions such as humidity and oxygen, an ideal fermentation environment is provided to promote the reproduction and metabolic activities of microorganisms, thereby improving the nutritional value and utilization rate of the organic microbial fertilizer.

[0051] The inner interlayer of the fermentation tank 1 and the sealing cover 2 are both provided with a polyurethane insulation layer, which can reduce the impact of the external temperature on the fermentation of the organic fertilizer and also prevent the rapid loss of temperature during the fermentation of the microbial organic fertilizer.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
