Description

Technical Field

[0001] The utility model belongs to the field of manure and sewage fermentation, in particular to a fermentation device for treating livestock and poultry manure and sewage in a breeding farm. Background Art

[0002] With the accelerated pace of intensification of livestock and poultry farming, highly automated farming has gradually taken shape, and farming and planting have become two industries. This has not only led to a significant reduction in the rate of returning livestock and poultry manure to the fields, but also caused the accumulation of manure in suburban livestock and poultry farming areas, polluting the surrounding environment. In order to alleviate this situation, fermentation equipment will be used to convert livestock and poultry manure into organic fertilizer or carry out other forms of treatment.

[0003] When fermenting fecal sewage, the fecal sewage is first transferred to the interior of the fermentation equipment, and then oxygen is injected into the fermentation equipment. Finally, the oxygen causes the fecal sewage to gradually ferment in the fermentation equipment, thereby effectively fermenting the fecal sewage into useful organic fertilizer. However, in actual use, since the fecal sewage is in a static state when fermenting in the fermentation equipment, it is not only prone to lack of oxygen, producing harmful gases and odors, but also affects the fermentation uniformity. At the same time, during the fermentation process, it is difficult to ensure the fermentation temperature of the fecal sewage, which in turn affects the activity of microorganisms and reduces the fermentation quality and efficiency of the fecal sewage.

[0024] Example 2

[0025] Reference Figure 1 、 2 and 4, which are the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the bottom of the inner cavity of the connecting disk 21 is fixedly connected to a transverse plate, and the bottoms of the driven wheel 24 and the driving wheel 23 are movably connected to the transverse plate through bearings, and the bottom of the connecting disk 21 is fixedly connected to the top of the fermentation tank 1.

[0028] like Figure 1 、 2 As shown in Figure 4, the stability of the driven wheel 24 and the driving wheel 23 can be ensured by the transverse plate. The external air will be sucked in by the centrifugal fan 31 and transmitted to the inner cavity of the air pipe 32. The air pipe 32 transmits the air to the inner cavity of the ring tube 33. Finally, the external air can be forced into the inner cavity of the fermentation tank 1 through the air injection hole on the top of the ring tube 33, thereby increasing the oxygen supply inside the fermentation tank 1 and facilitating the fermentation operation of the fecal sewage.

[0029] Example 3

[0030] Reference Figure 1-3 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0031] In this embodiment, the bottom of the inner cavity of the fermenter 1 is fixedly connected to the bottom plate 251 , the bottom of the transmission rod 25 is movably connected to the top of the bottom plate 251 via a bearing, and the bottom of the fermenter 1 is fixedly connected to the base 14 .

[0033] The output end of the temperature sensor 4 is connected to the input end of the microcontroller 5 , and the output end of the microcontroller 5 is connected to the input ends of the motor 22 and the centrifugal fan 31 respectively.

[0034] like Figure 1-3 As shown, the fermented fecal and sewage can be discharged through the drain pipe 11 for later use. The ventilation pipe 12 can be used to ventilate the interior of the fermentation tank 1 to facilitate oxygen circulation and improve the fermentation quality. The fecal and sewage can be transferred to the fermentation tank 1 for fermentation through the liquid injection hopper 13. The fermentation tank 1 can be stably supported by the base 14. The temperature sensor 4 and the microcontroller 5 are connected to receive the temperature data monitored by the temperature sensor 4, and the temperature data can be compared and analyzed. The microcontroller 5 is respectively connected to the motor 22 and the centrifugal fan 31 to control the opening or closing of the centrifugal fan 31 and the motor 22.

The fecal sewage is stirred dynamically to keep it in an active state, so as to facilitate the reaction with oxygen and improve the uniformity of the fecal sewage. While stirring, the internal temperature of the fermentation tank 1 can be monitored by the temperature sensor 4, and the monitored temperature value is transmitted to the microcontroller 5. The microcontroller 5 compares the temperature value. When the temperature value is lower than the preset temperature value, the microcontroller 5 can control the electric heating tube 28 to start operation, so that the electric heating tube 28 generates heat and transfers it to the connecting tube 27, and the connecting tube 27 transfers the heat to the fermentation tank 1 and the fecal sewage. The fecal sewage is heated by the connecting tube 27 in cooperation with the electric heating tube 28, so that the temperature of the fecal sewage and the internal temperature of the fermentation tank 1 are within the preset fermentation temperature value range, thereby keeping the inside of the fermentation tank 1 in a constant temperature state, which is convenient for promoting microbial activity and improving fermentation efficiency and quality.
