[0002] With the vigorous development of intensive breeding industry in my country, a large amount of livestock and poultry manure will be produced. Livestock and poultry manure is a usable resource after harmless treatment. The current harmless treatment technology for livestock and poultry manure is roughly divided into fertilizer technology, feed technology and energy technology. Among all livestock and poultry manure treatment and utilization methods, biological aerobic high-temperature fermentation has become the preferred treatment method at home and abroad, because its entire fermentation process is carried out in a reactor with a high degree of harmlessness, and stirring and temperature control during the fermentation process can greatly reduce the fermentation time and improve the degree of maturity. However, the structure of the reactor used for livestock and poultry manure fermentation in the existing technology is too simple. After the fermentation is completed, the reactor takes a long time to dissipate heat. At the same time, the cleaning inside it is troublesome and takes a lot of time, which greatly affects the efficiency of the reactor. Utility Model Content

When the slider 41 is at the lowest level, the kettle cover 22 is closed on the kettle tank 21, and the stirring end of the stirring mechanism 5 is located inside the kettle tank 21. When the slider 41 is at the highest level, the kettle cover 22 is away from the kettle tank 21, and the stirring end of the stirring mechanism 5 is located outside the kettle tank 21. When harmlessly treating livestock and poultry manure, the livestock and poultry manure is first injected into the kettle tank 21, and then the column 3 is rotated to make the kettle The lid 22 is located directly above the kettle 21, and the screw mechanism 4 is rotated to adjust the position of the slider 41 so that the kettle lid 22 is closed on the kettle 21, so that the livestock and poultry manure can be fermented and treated harmlessly. In the process of fermenting livestock and poultry manure, the livestock and poultry manure can also be stirred by the stirring mechanism 5, thereby improving the fermentation quality; after the fermentation is completed, the kettle lid 22 can be opened to shorten the heat dissipation time of the material inside the kettle 21; when cleaning is required, the screw mechanism 4 is adjusted to make the slider 41 drive the kettle lid 22 to move upward. When the stirring mechanism 5 assembled on the kettle lid 22 is completely outside the kettle 21, the column 3 is rotated to drive the stirring mechanism 5 on the kettle lid 22 away from directly above the kettle 21. At this time, the stirring end of the stirring mechanism 5 and the kettle 21 can be cleaned.
