Embodiment 1

[0040] As shown in the figure, an intelligent preparation system for straw ecological compound fertilizer includes a cutting unit, a fermentation unit, an intelligent control unit, a waste heat recovery unit, a filter press unit, a grinding and crushing unit, a mixing unit, a granulation drying unit, and a finished product distribution unit. The fermentation unit includes a fermentation tank 1, a biogas recovery mechanism 2, a heating mechanism 3, a heat exchange mechanism 4, a spray mechanism 5, an automatic feeding mechanism 6 and a stirring mechanism 7 and an intelligent temperature control unit. The intelligent temperature control unit includes temperature The sensor 8 and the intelligent control chip, the fermentation tank has a cavity for straw fermentation, the temperature sensor 8 and the stirring mechanism 7 are arranged in the cavity, and there are multiple temperature sensors 8 which can be distributed on the inner wall of the cavity and the stirring mechanism , The i...

Embodiment 2

[0047] A preparation method for synthesizing high-efficiency ecological fertilizer by using straw microbial fermentation, using biological straw as the main raw material and animal manure as the starter, the specific preparation method is as follows:

[0048] S1. Cut waste biological straw into straw sections with a length of 5-10cm, and use an automatic feeding mechanism to load it into the fermentation tank from the feed opening on the top of the fermentation tank, and then use 10 times the amount of fresh animal manure according to the ratio of 2% of the straw weight. After the water is diluted and stirred, it is sprayed onto the straws in the tank through a spraying mechanism, and the stirring mechanism is started to mix the fecal liquid and the straws evenly; during the initial feeding, the heating mechanism is used to rapidly increase the temperature in the tank to above 30°C, and then closed natural fermentation , The fermentation period is 3-5 days; during the fermentation...

Embodiment 3

[0056] A preparation method of using straw microbial fermentation to synthesize quick-acting slow-release integrated high-efficiency ecological fertilizer. The steps are the same as in Example 2, except that the step S4 is: adding 25-30% dry clay powder to the straw powder obtained by grinding in step S3 according to its weight , 15-20% inorganic fertilizer, mix and stir evenly, ventilate and dry after granulating by a granulator to obtain ecological compound fertilizer. The inorganic fertilizer is any one or more combinations of N fertilizer, P fertilizer, potash fertilizer or other inorganic fertilizers acceptable to crops, and the combination ratio can also be adjusted reasonably according to the different soil quality of the fertilizer application area.

Abstract

The invention discloses an intelligent preparation system and preparation method for synthesizing a quick-acting and slow-release integrated efficient ecological compound fertilizer through straw microbial fermentation. The system comprises a cutting unit, a fermentation unit, an intelligent control unit, a waste heat recovery unit, a press filtration unit, a grinding and crushing unit, a blending unit, a granulation and drying unit and a finished product sub-packaging unit, wherein the fermentation unit comprises a fermentation tank, a biogas recovery mechanism, a heating mechanism, a heat exchange mechanism, a sprinkling mechanism, an automatic feeding mechanism and a stirring mechanism. The method comprises the following steps: performing sealed fermentation on straws and animal feces; and performing water press filtration on a fermentation product, then performing high-temperature inactivation, adding an appropriate amount of inorganic quick-acting fertilizer and trace element fertilizer, rooting powder, a drought-resistant water retention agent and clay, mixing, and performing granulation and drying to obtain the compound fertilizer. By adopting the system and the method disclosed by the invention, fresh animal feces are used as a leaven which contains a lot of microorganism bacteria and digestive enzymes and can promote biological degradation and decomposition of the straws; and moreover, the animal feces are further fermented to be beneficial for opening unstable ester bonds in straw cellulose, accelerating the degradation of the straws and shortening the fermentation period.

Description

Technical field [0001] The invention belongs to the technical field of biological fermentation of agricultural straw resources, and specifically relates to an intelligent preparation system and a preparation method for synthesizing quick-acting slow-release integrated high-efficiency ecological compound fertilizer by using straw microbial fermentation. Background technique [0002] 1. The incineration of straw wastes resources and causes great harm. [0003] Hazard 1: Pollution of the air environment, endangering human health. Data shows that when straw is burned, the three pollution indexes of sulfur dioxide, nitrogen dioxide, and inhalable particulate matter in the atmosphere reach high peaks. The concentration of sulfur dioxide is twice as high as usual, and the concentration of nitrogen dioxide and inhalable particulate matter is higher than usual. 3 times higher, which is equivalent to the fifth level of the average daily concentration. When the concentration of inhalable pa...
