Embodiment 1

[0047] see Figure 1-6 , This embodiment provides a small-scale energy-saving and efficient composting equipment for livestock and poultry manure heated by hot air. In this embodiment, the equipment includes a frame 13, a stack fermentation system, an aeration and heating system, a control system and a power supply system.

[0048] The frame 13 includes a middle bottom plate 131 , a push handle 132 , an upper bottom plate 133 , a frame 134 , a plurality of right-angle fixing pieces 135 , a support piece 136 , a bottom bottom plate 137 , a support piece 2 138 and a plurality of universal wheels 139 . The middle base plate 131 is installed in the middle of the frame 134 , and the upper base plate 133 is installed in the upper portion of the frame 134 . The bottom bottom plate 137 is mounted on the bottom of the frame 134 and is used to support the pneumatic agitator 7 , support one 136 and support two 138 . Push handle 132 is installed on the frame 134, can be pushed and pulle...

Embodiment 2

[0070] This embodiment provides a small-scale livestock and poultry manure composting equipment heated by hot air and energy-saving and high-efficiency. On the basis of Embodiment 1, the control mode of the fermentation controller in the composting process is described. Wherein, the composting process of the compost includes a heating stage, a high temperature stage and a decomposing stage (also called a cooling stage). Among them, the high-temperature stage has the greatest impact on the composting degree of composting. The composting technology in this embodiment is a high-temperature aerobic composting technology, that is, during the composting process, the composting needs to be in contact with the air and the composting temperature needs to reach a certain range to effectively kill Pathogens and inactivation of plant seeds to improve compost maturity and organic fertilizer quality. Next, this embodiment introduces these three processes respectively.

[0071]In the heatin...

Embodiment 3

[0077] This embodiment provides a small-scale livestock and poultry manure composting method heated by hot air and energy-saving and high-efficiency. The composting method adopts an aeration heating mode or an aeration mode according to different situations, so as to adjust the composting temperature and the oxygen content of the fermentation bin. Wherein, the small-scale livestock and poultry manure composting method includes the following steps.

[0078] (1) Collect the temperature and humidity information of the stockpiles.

[0079] (2) Detect the oxygen content in the fermenter 8 .

[0080] (3) According to the temperature and humidity information and oxygen content, based on the preset heating mode and ventilation mode, the heating box 2 and the air pump 1 are controlled to realize the fermentation condition control of composting materials in different composting stages; wherein, the composting process of composting materials includes Heating stage, high temperature sta...

Abstract

The invention discloses hot air heating, energy-saving and efficient small livestock and poultry manure composting equipment and method. The equipment comprises a rack, a stacking fermentation system,a ventilation heating system and a control system. The stacking fermentation system comprises a fermentation bin, a pneumatic stirrer, an aeration pipeline, an exhaust pipeline and a deodorization device. The fermentation tank is used for containing stacked materials and is of a double-layer structure, and a thermal insulation material is placed in an interlayer. The pneumatic stirrer comprises an air cylinder, a fixed transverse plate, a rotating shaft and stirring blades. The ventilation heating system comprises an air pump, a three-way connector and a heating box. The air pump generates two independent ventilation lines through the three-way connector. The heating box is used for receiving and heating the gas conveyed by one ventilation line and dispersing the heated hot gas into the fermentation tank. The other ventilation line is used for driving the rotating shaft to rotate through the air cylinder. The control system comprises a detection device and a fermentation controller. The hot air heating, energy-saving and efficient small livestock and poultry manure composting equipment and method are beneficial to the miniaturization, high efficiency and simple operation development of the equipment, and enhance the fermentation rate.

Description

technical field [0001] The invention relates to composting equipment in the field of composting technology, in particular to a small-scale livestock and poultry manure composting equipment heated by hot air and energy-saving and high-efficiency, and also relates to a method for composting small-scale livestock and poultry manure heated by hot air and energy-saving and high-efficiency. Background technique [0002] China's animal husbandry industry has developed rapidly. Since the 1960s, my country's livestock and poultry breeding areas have always maintained a high-speed development momentum. The number of livestock and poultry stocks has increased year by year, followed by a rapid increase in the production of livestock and poultry manure. my country's livestock and poultry manure is mainly pig manure, cow manure, sheep manure and chicken manure, and these four types of manure account for more than 90% of the total. The problem of livestock and poultry manure pollution has ...
