Embodiment 1

[0051] 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.

[0052] Such as figure 1 Shown, a kind of rice husk and sludge co-fermentation process comprises the following production steps:

[0053] a. feeding process, quantitative rice husk, sludge and fermented liquid are added into the fermenter body;

[0054] b. Stirring process, start the impeller 4, 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;

[0055] c. Filtration process, when the material in the circulation process in step b passes through th...

Embodiment 2

[0065] Such as Figure 2 to Figure 9 As shown, a rice husk and sludge synergistic fermentation tank includes a tank body 1, a drive member 2 arranged on the end cover of the tank body 1, a rotating shaft 3 driven by the drive member 2 and extending into the tank body 1, and The impeller 4 arranged at the end of the rotating shaft 3; the rotation of the impeller 4 agitates the feed liquid in the tank body 1 so that the liquid material in the tank body 1 forms an upward circulation of the middle downward side;

[0066] The tank body 1 is provided with a crushing barrel 5 fixed on the inner wall of the tank body 1, the rotating shaft 3 passes through the crushing barrel 5, and the crushing barrel 5 is provided with a crushing mechanism 6 and a throwing mechanism 7. A discharge hole a51 is provided on the side wall of the barrel 5, and the crushing mechanism 6 crushes the slag in the crushing barrel 5, and the crushed material enters the tank body 1 through the discharge hole a51 ...

Abstract

The invention relates to the technical field of fermentation, in particular to a rice husk and sludge collaborative fermentation process. The rice husk and sludge collaborative fermentation process includes the following steps of a, a feeding process, specifically, adding quantitative rice husk, sludge and fermentation liquid into a fermentation tank; b, a stirring process, specifically, startingimpellers, stirring materials in the tank, thusthe materials form circulation with a downward middle part and an upward side part; c, a filtering process, specifically,the materials in the circulationprocess passing through a filtering part, large particles and agglomerated slag materials slide into a crushing barrel along the inner wall of the filtering part; d, a crushing process, specifically,the large particles and the agglomerated slag materials entering into the crushing barrel and move downwards with liquid flow under the suction of impeller rotation, and a crushing mechanism crushes the materials in the downward process; and e, a dumping process, specifically,in the process that the crushing mechanism crushes the materials in the step d, a dumping mechanism rotates at the same time, the dumping mechanism dumps the crushed materials with proper particle size from a discharging hole formed in the side wall of the crushing barrel, and problems of slags caking and slow fermentation of the large particles in the fermentation process are solved.

Description

technical field [0001] The invention relates to the technical field of fermentation equipment, in particular to a collaborative fermentation process of rice husk and sludge. Background technique [0002] Waste gas such as rice husk and sludge still have their own utilization value. Reasonable use can not only save resources but also protect the environment. Some anaerobic fermentation equipment is used to ferment rice husk and sludge. Resource utilization is realized, but there are various problems in actual operation, especially the problem of low fermentation efficiency and high energy consumption. [0003] The Chinese utility model patent with the publication number CN205096222U. discloses an anaerobic digestion sweeping and slag breaking device and an anaerobic digestion treatment system, including at least one diversion cylinder, and each diversion cylinder is vertically fixed on the anaerobic reactor On the side wall, as well as to blow the digested material to break ...
