Problems solved by technology

[0007] The purpose of the present invention is to address the deficiencies of the prior art, and provide a small-scale high-temperature anaerobic digestion device for agricultural waste and sludge. By setting a stirring mechanism, the liquid material in the tank is stirred to form the material in the middle to the material on the side. Upward circulation, combined with the setting of the filter mechanism and the crushed material bucket, makes the large material and part of the agglomerated slag in the liquid material filtered out into the crushed material tank, under the action of the crushed material tank crushing mechanism and the crushed material output mechanism After being fully crushed, it is sent back to the tank for fermentation, which solves the technical problems of single structure of existing fermentation equipment, low fermentation efficiency, easy agglomeration of slag during fermentation, and large particles in slag that affect fermentation efficiency

Embodiment 1

[0043] 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.

[0044] Such as Figure 1 to Figure 10 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 filtering mechanism 2, a crushing mechanism 3, a broken material output mechanism 4 and a stirring mechanism 5 from top to bottom;

[0045] The stirring mechanism 5 stirs the feed liquid in the tank body ...

Embodiment 2

[0061] Such as image 3 and Figure 4 As shown, the parts that are the same as or corresponding to those in Embodiment 1 adopt the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences between Embodiment 1 and Embodiment 1 are described below; the differences between Embodiment 2 and Embodiment 1 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;

[0062] 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 the circumferential direction, a lower roller...

Abstract

The invention relates to the field of fermentation equipment, in particular to a small agricultural waste and sludge high-temperature anaerobic digestion device. The device comprises a tank body, wherein a driving part is arranged on the tank body, a crushing bucket is arranged in the tank body, and filtering, smashing, crushed material output and stirring mechanisms are sequentially arranged along the crushing bucket from top to bottom; the stirring mechanism is used for stirring material liquid in the tank body so as to form a circulation of the middle material down and the side material up,the filtering mechanism filters the material in the circulation process, the filtered slag materials are introduced into the crushing bucket, the crushing mechanism is used for crushing the slag materials in the crushing bucket, the crushed materials fall into the crushed material output mechanism, and the crushed materials are intermittently pushed into the material liquid of the tank body in the rotation process of the crushed material output mechanism; and a rotating shaft is driven by the driving part to rotate and penetrates through the crushing bucket and the end part of the rotating shaft is connected with the stirring mechanism. According to the small agricultural waste and sludge high-temperature anaerobic digestion device, the technical problems that the existing fermentation equipment is single in structure, low in fermentation efficiency, prone to caking of slag materials in the fermentation process and large in particulate matter in the slag materials to influence the fermentation efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of anaerobic digestion equipment, in particular to a small-scale high-temperature anaerobic digestion device for agricultural waste and sludge. Background technique [0002] The resource utilization of agricultural waste is very necessary. It can not only solve the problem that a large amount of agricultural waste is prone to pollution, but also obtain valuable resource products from it. It can be described as the best of both worlds, but in the process of realizing resource utilization Various technical problems will be encountered in the process, such as the low fermentation efficiency and high energy consumption of the existing fermentation technology during anaerobic fermentation treatment, which ultimately outweighs the gains. [0003] The Chinese utility model patent with the publication number CN205096222U. discloses an anaerobic digestion sweeping and slag breaking device and an anaerobic digestion t...
