Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a dry anaerobic fermentation device. Background Art

[0002] Dry anaerobic fermentation is a process for producing biogas from solid organic waste. It has important applications in urban environmental protection, especially in the treatment of urban domestic waste, livestock manure and sludge. It has the advantages of low raw material pretreatment requirements, low biogas slurry production, low energy consumption and easy management.

[0003] During the dry anaerobic fermentation process, material samples need to be taken at multiple time stages for processing and determination of relevant indicators; however, during sampling, due to the complex composition of the fermentation material, it is often mixed with many impurities (such as shredded plastic bags, etc.), which makes the sampling valve easily blocked.

[0004] A dry anaerobic fermentation device is proposed in a Chinese patent with publication number CN217025943U; a set of pneumatic valves is added to ensure the accuracy of the sampling results; and when the second valve and the third valve are blocked, the material can be blocked with the help of the previous valve, and then the valve can be manually unblocked to avoid large-scale leakage of materials and ensure a clean and hygienic production environment.

[0005] Although the above technical solution can prevent valve blockage, in actual operation, most of the materials entering the dry anaerobic fermentation equipment are solid materials that have been minced or crushed by a crusher, and most of the water has been lost during the mincing or crushing. After entering the dry anaerobic fermentation equipment, these materials will be continuously stirred by the stirring blades, and often entangled with each other and become very tight. In actual practice, the samples described in the above technical solution often cannot flow into the sampling bucket by gravity, which ultimately leads to a slow sampling process or even failure to complete the sampling.

[0006] As is known from the above, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
