Description

Technical Field

[0001] The utility model belongs to the technical field of composting and fermentation devices, in particular to a fast static composting device for livestock and poultry excrement and straw. Background Art

[0002] The rapid development of agriculture has led to a large amount of agricultural waste generated every year. A large amount of agricultural waste (livestock and poultry manure and straw) is directly discharged or improperly handled, which will cause environmental problems such as water pollution and air pollution. For many years, traditional aerobic composting has been considered an attractive alternative for treating organic waste and animal manure because it is less polluting to the environment and more sustainable. However, the traditional composting process is time-consuming and requires several stages, including heating, high temperature, cooling and decomposition stages, which takes weeks to months to reach maturity. In addition, traditional composting requires a large outdoor site, and it is time-consuming and labor-intensive to dig aeration channels on the site. The aeration channels are easily blocked by the pile, which will cause poor ventilation and affect the activity of microorganisms, thereby increasing the time of the composting decomposition stage and affecting the fertilizer efficiency. At the same time, traditional composting is restricted by weather temperature and cannot effectively regulate the temperature of the compost, which will also affect the activity of microorganisms, increase the time of the decomposition stage and affect the fertilizer efficiency.

[0023] The working principle of this utility model is:

[0024] When in use, the animal manure and straw rapid static composting device can be set in an adjustable sealed indoor space, which can effectively reduce the odor generated during composting, prevent the odor from spreading, reduce the space occupied by composting, and effectively reduce the impact of weather on composting by controlling the indoor temperature; when composting, the raw materials are placed in the annular cavity 1-2, so that the raw materials are fermented in the annular cavity 1-2. The device is connected to an external power supply, and the motor 3-1 is energized to drive the wind wheel 3-3 to rotate through the rotating shaft 3-2, and air is sucked in through the upper opening of the cylindrical cavity 1-3, and is sent into the raw materials in the annular cavity 1-2 through the wall of the cylindrical cavity 1-3, which can replace the traditional excavation of airways to transport oxygen to the raw materials, and can also solve the problem that the traditional airways are easily blocked; the guide plug 2-4 is pulled upward to drive the sliding rod 2-2 to move upward along the fixed frame 2-1, so that the multi-stage frustum can be respectively located at the openings of the cylindrical cavities 1-3 The opening of the multi-stage truncated cone and the cylindrical cavity 1-3 can be adjusted, so that the amount of air sucked by the wind wheel 3-3 can be adjusted to adjust the temperature and oxygen of the raw materials. The adjustment can be made according to the fermentation of the raw materials. That is, the smaller the diameter of the multi-stage truncated cone and the larger the gap at the opening of the cylindrical cavity 1-3, the more air is sucked, and the temperature of the raw materials can be reduced and the oxygen can be increased. When the sliding rod 2-2 moves along the fixed frame 2-1, the positioning holes 2-3 cooperate with the beads to locate the position of the sliding rod 2-2, thereby positioning the guide plug 2-4; the motor 2 4-1 is powered on to drive the screw 4-2 to rotate, and through the limit of the guide column 4-3, the sliding ring 4-4 ​​connected by the screw connection moves upward. The sliding ring 4-4 ​​moves upward and turns the raw materials through the material diverting column 4-5, which can replace the traditional manual composting and increase the work efficiency. The motor 2 4-1 can be controlled to rotate in the opposite direction to reset. After the composting is completed, the fertilizer can be taken out.
