[0002] Composting is the most widely used and most economical method for the comprehensive utilization of organic waste. Organic waste composting is a process that uses organic waste as the main raw material under aerobic conditions. Through aerobic biological action, the organic matter in the waste is decomposed into organic matter, and pathogens and parasite eggs are killed, and the fertilizer content is increased. The fertilizer produced can be used for agricultural and gardening purposes. It is a comprehensive treatment technology that is harmless, reduces volume, and stabilizes. The commonly used windrow composting has a long fermentation cycle and requires special management. Organic waste such as livestock and poultry manure and sludge has a large specific gravity and is viscous. After stacking, The pile is limp and cannot be piled high, and the processing capacity per unit area is low. Conventional composting technology is difficult to handle large amounts of garbage. It is often unable to operate in winter due to climate influences and occupies a large area. Since the compost products contain a large amount of grass seeds and need to be turned and aerated regularly, in an open-air environment, a large amount of odor, dust, and flies and harmful bioaerosols will be generated during the fermentation and turning process, which will have a certain impact on practitioners and surrounding residents. Many processing companies have received complaints or have been closed due to substandard emissions, seriously affecting the healthy development of the waste composting industry.

DETAILED DESCRIPTION

[0025] The following is a specific implementation example of the present invention, which is described in detail with reference to the accompanying drawings. It should be noted that the scope of application of the present invention is not limited to the following embodiments, and all similar structures based on the present invention are within the scope of application of the present invention.

[0026] The utility model is a low-consumption and emission-reducing aerobic fermentation device, such as Figure 1As shown, the fermentation device includes: a box body, which includes a box bottom formed by splicing a plurality of fermentation box modules 1, so it can be spliced ​​according to the actual processing capacity of the user, the top horizontal sides of the fermentation box module 1 are detachably connected with side walls 2, and the tops of the side walls 2 on both sides are detachably connected with a roof 3, and slide rails 4 are provided on the horizontal sides of the box body. Since the fermentation box module 1, the side walls 2 and the roof 3 are detachably connected, it is only necessary to tidy up and level the site during operation, and the fermentation box module 1, the side walls 2 and the roof 3 can be quickly installed and disassembled without changing the nature of the land and causing pollution to the land.

[0027] A self-propelled turner 5 is slidably connected to the slide rails 4 on both sides. The self-propelled turner is used to turn the pile. A leachate recovery device for recovering leachate is processed under the ground at the bottom of the box. This device is a prior art device.

[0028] like Figure 5 As shown, it also includes: an aeration component, which is arranged inside the fermentation box module 1, and the aeration component includes a blower 6. The input and output ends of the blower 6 are both connected to a connecting pipe 7, and one end of the connecting pipe 7 is connected to a storage tank 8. The blower 6 is installed in the wall on the side of the feed door 9, so that the hot air in the device can be used to aerate the pile during ventilation and aeration in winter, making the device more suitable for all-weather operation. The storage tank 8 is a buried leachate storage tank, and stainless steel perforated pipes are laid in the two aeration pipe reserved grooves 101, and ceramsite is laid on top to fill the aeration pipe reserved grooves 101.

[0029] According to an optional embodiment of the present invention, Figure 4 As shown, the fermentation box module 1 includes: an aeration pipe reserved groove 101 and a connecting groove 102 symmetrically arranged at the bottom. The connecting groove 102 is opened on one side of the surface of the fermentation box module 1, and the other side of the fermentation box module 1 is connected to a connecting block 103 adapted to the connecting groove 102, which facilitates the accurate connection of the two prefabricated modules and reduces leakage at the joints.

[0030] It also includes a plurality of communication holes 104 , which are all arranged inside the fermentation box module 1 .

[0031] According to an optional embodiment of the present invention, a feed door 9 and a discharge door 10 are installed at both longitudinal ends of the box body.

[0034] According to an optional embodiment of the present invention, the roof 3 is covered with a waterproof and odor-proof film material, which not only ensures that the air and water vapor and carbon dioxide generated by the compost can freely enter and exit the box, but also intercepts the odor generated by the compost in the box, greatly reducing the overflow of nitrogen nutrients and preventing air pollution. The waterproof and breathable microporous membrane can be replaced when it hardens, ages or the air permeability decreases.

[0035] The working method of the utility model is as follows:

[0036] First, the feed door 9 is opened, and the mixed material is shoveled into the box by the loader. When the mixed material needs to be turned over, the self-propelled turner 5 is opened for turning. At this time, the self-propelled turner 5 will move back and forth along the slide rail 4, thereby moving the mixed material at the feed door 9 to the discharge door 10. During the fermentation process, the leachate generated by the mixed material will flow into the leachate recovery device. When it is in the high-temperature fermentation stage, the blower 6 is started, and the material is forced to be ventilated through the pipe at the bottom of the box, so that a slight positive pressure is formed in the box, providing a good aerobic composting environment for the material, reducing the material from entering the anaerobic state during the fermentation process and generating odor. The generated odor is processed by the deodorizing component 11 and the dehumidifying component 12. When the mixed material in the box is fermented, the discharge door 10 is opened and the fermented material can be shoveled out by the loader.
