Embodiment 1
[0060] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0061] Such as figure 1 As shown, a small-scale agricultural waste and sludge high-temperature anaerobic digestion method includes the following production steps:
[0062] a. Feeding process, adding quantitative agricultural waste, sludge and fermentation liquid into the fermentation tank body;
[0063] b. agitation process, start the agitation mechanism 5, and stir the material in the tank, so that the material in the middle forms an upward circulation of the material on the lower side;
[0064] c. Filtration process, when the...
Embodiment 2
[0076] Such as Figure 2 to Figure 11 As shown, a small-scale agricultural waste and sludge high-temperature anaerobic digestion device includes a tank body 1, a drive member 11 is arranged on the tank body 1, and a crushing bucket 12 is arranged inside the tank body 1, along the The broken material barrel 12 is provided with a filter mechanism 2, a crushing mechanism 3, a broken material output mechanism 4 and a stirring mechanism 5 from top to bottom;
[0077] The stirring mechanism 5 stirs the feed liquid in the tank body 1 so that the material in the middle of the tank body 1 circulates downward and the material on the side is upward, and the filter mechanism 2 filters the material in the circulation process, and The filtered slag is introduced into the crushed material barrel 12, and the crushing mechanism 3 crushes the slag in the crushed material barrel 12, and the crushed material falls into the crushed material output mechanism 4, and the crushed material is output D...
Embodiment 3
[0093] Such as Figure 4 with Figure 5 As shown, the parts identical or corresponding to those in the second embodiment adopt the reference numerals corresponding to the second embodiment. For the sake of simplicity, only the differences between the second embodiment and the second embodiment are described below; the difference between the third embodiment and the second embodiment The difference is that: further, the crushing knife assembly 31 includes an upper blade 311, a lower blade 312 fixedly arranged on the inner wall of the crushing bucket 12 along the circumferential direction, a lower blade 312 arranged up and down, and a rotating blade fixedly arranged on the rotating shaft 13 along the circumferential direction 313, the rotating blade 313 rotates through between the upper blade 311 and the lower blade 312;
[0094] The crushing assembly 32 includes an upper roller 321, a lower roller 322 that is rotatably arranged on the inner wall of the crushing bucket 12 in th...
