The approach that natural pond liquid utilizes mainly contains also field, seed soaking, foliage application, fodder additives etc., but these approach are not widely used, reason has several: natural pond liquid directly can not be brought use, and needing needs to blend into the diluent of different concns by difference or be used after carrying out disinfection; Do not consider after long-time use underground water, air and the problem naturally causing secondary pollution; There is limitation, as used the limitation in season, using the limitation etc. of object, these limitation to make the consumption of natural pond liquid little, a large amount of natural ponds liquid that large-scale cultivation factory anaerobically fermenting of cannot dissolving produces.
Summary of the invention
The present invention is that the natural pond liquid after solving anaerobically fermenting directly can not bring use, need need to blend into the diluent of different concns according to difference or be used after carrying out disinfection, and long-time use to underground water, air and can cause secondary pollution naturally, use season, use object also to have confinement problems, and then propose a kind of feces of livestock and poultry anaerobic ferment devices with natural pond liquid reflux pipeline.
The present invention is the technical scheme taked that solves the problem: a kind of feces of livestock and poultry anaerobic ferment devices with natural pond liquid reflux pipeline of the present invention comprises feeding unit, feed pipe, anaerobic fermentation tank, biogas pipeline, Digestive system pipeline, solid-liquid separating machine, natural pond slag pipeline, natural pond liquid first pipeline, natural pond liquid hold-up vessel, natural pond liquid second pipe, natural pond liquid the 3rd pipeline and natural pond liquid reflux line, feeding unit is communicated with anaerobic fermentation tank by feed pipe, anaerobic fermentation tank is communicated with a biogas pipeline, anaerobic fermentation tank is also communicated with solid-liquid separating machine by a Digestive system pipeline, solid-liquid separating machine and a natural pond slag pipeline communication, solid-liquid separating machine is also communicated with natural pond liquid hold-up vessel by natural pond liquid first pipeline, natural pond liquid hold-up vessel is communicated with a natural pond liquid second pipe, natural pond liquid second pipe and one article of natural pond liquid the 3rd pipeline communication, natural pond liquid second pipe is also communicated with feeding unit by a natural pond liquid reflux line.
The invention has the beneficial effects as follows: beneficial effect of the present invention have following some:
1, whole anaerobic fermentation process and natural pond liquid reflux course are all Automated condtrol, and technique is simple, easy and simple to handle;
2, natural pond liquid enters feeding unit by the backflow of natural pond liquid reflux line, the organic matter completely that do not ferment in the liquid of natural pond can be utilized again, improves anaerobic fermentation gas production efficiency;
3, the hot water needing in fermentation raw material to convert is replaced to natural pond liquid, not only reduce the consumption of water, and the water added needs power consumption heating to meet the requirement of fermentation raw material temperature, and the natural pond liquid of backflow itself is with heat, decreases energy consumption, has saved cost;
4, natural pond liquid is refluxed, greatly reducing the quantity that anaerobic ferment devices natural pond liquid is arranged outward, and then decrease the secondary pollution that causes of environment to external world of natural pond liquid, and by season and the restriction using object.
