Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural waste treatment, in particular to a device for aerobic and anaerobic coupled fermentation of pig manure. Background Art

[0002] Pig manure has a fine texture and contains more organic matter and nitrogen, phosphorus and potassium nutrients. It decomposes slowly and is suitable for base fertilizer. The manure of one pig can increase grain production by 200-300 kilograms. Under modern pig farming conditions, pig manure treatment is a key environmental protection technology, otherwise it will cause environmental pollution. After scientific treatment of fertilizer fermentation, pig manure can be added to high-quality organic fertilizer to achieve zero pollution, zero emissions, and no odor, turning manure into gold. Pig manure needs to be fermented in the recycling of pig manure. After searching, the patent with application number 202022457757.7 discloses a device for aerobic and anaerobic coupled fermentation of pig manure, including a fermentation box with an open top, a sealing cover that can be covered on the fermentation box, a top plate, a sealing cover lifting assembly, a fan and a gas collection chamber; the bottom wall of the inner cavity of the fermentation box is evenly opened with a plurality of threaded holes and fixedly connected to a heat-conducting tube that covers the threaded holes therein; the heating rod can be connected to the inner cavity of the fermentation box by threads; the fan is connected to the inner cavity of the fermentation box; the fermentation box and the gas collection chamber are connected; the top plate is horizontally supported above the fermentation box; and the sealing cover lifting assembly is supported on the top plate.

[0003] However, during actual use, the applicant found that when the pig manure inside the fermentation box is heated by the heat-conducting cylinder, due to the relative stillness of the heat-conducting cylinder and the pig manure, the pig manure close to the heat-conducting cylinder can be heated quickly, while the pig manure far away from the heat-conducting cylinder needs a longer time to be heated, which makes the heating of the pig manure very uneven, thereby affecting the heating efficiency and heating effect. In view of this, we propose a device for aerobic and anaerobic coupled fermentation of pig manure. Utility Model Content
