Embodiment 1

[0036] Such as Figure 1-3 As shown, a device for preparing multi-effect compound fertilizer by intelligently controlling straw fermentation includes: double-tower fermenter 10, crushing mechanism 20, automatic feeding mechanism 30, automatic discharging mechanism 40, monitoring front end 50, communication base station and intelligent monitoring terminal The monitoring front end 50 is arranged on the double-tower fermentation tank 10, the monitoring front end 50 communicates with the communication base station through the GPRS network, and the communication base station communicates with the intelligent monitoring terminal through the Internet network, and the monitoring front end realizes the monitoring of the operation data in the fertilizer making device, Collection and transmission; such as the fermentation temperature, humidity, nutrient addition status of the fermented liquid, fermentation quality and time in the fertilizer making device, the monitoring front end transmit...

Embodiment 2

[0052] A process for developing multifunctional fertilizers with high value of straw, the steps are:

[0053] (1) Feed the crop stalks into the crushing mechanism for crushing, such as wheat stalks and corn stalks, and carry out crushing according to different specifications of different stalks, generally according to the length not longer than 5cm, to obtain straw debris;

[0054] (2) Spray the fermenting agent on the crushed straw debris, stir and mix them, and then input them into the double-tower fermentation tank through the automatic feeding mechanism to seal them for anaerobic fermentation and decomposing, and use the fermentation heat to naturally inactivate, sterilize and kill pests; The physical properties, chemical properties and mechanical properties are different, and the fermentation temperature and time are also different. Generally, it is ensured that the temperature in the double-tower fermentation tank is not higher than 55°C, and the time is 4-10 days; and th...

Abstract

The invention discloses a special fermenting device for high-value development of a multifunctional fertilizer by utilizing straws. The special fermenting device comprises a double-tower fermenting tank, a crushing mechanism, an automatic feeding mechanism and an automatic discharging mechanism; one end of the automatic feeding mechanism is connected with a material outlet end of the crushing mechanism; the other end of the automatic feeding mechanism is connected with a material inlet section of the double-tower fermenting tank; the automatic discharging mechanism is connected with the bottom of the double-tower fermenting tank; an interlayer is arranged in an outer shell of the double-tower fermenting tank; the interlayer is connected with first heat exchange equipment; a heat exchange pipe is arranged in the first heat exchange equipment; the heat exchange pipeline is loaded with a refrigerant internally; an outlet of the heat exchange pipeline is connected with second heat exchange equipment. The overall equipment is high in automation degree and low in energy consumption, and can realize continuous scale production; the product decomposition period is short; the cost is low; the yield is high; the fertilizer efficiency is high; the technology is mature; the process is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer fermentation equipment, in particular to a special fermentation device for the development of multifunctional fertilizers by using straw to increase the value. Background technique [0002] my country is a large agricultural country, and the amount of straw produced is huge. These organic resources are mostly discarded or even burned because they cannot be effectively utilized, resulting in huge waste of resources and environmental pollution. In 2008, the State Council issued the "Opinions on Accelerating the Comprehensive Utilization of Crop Straws". Utilization of resources, and strive to achieve a utilization rate of straw resources of more than 80% by 2015. In terms of scientific research investment, the central government supports scientific research projects including straw resource utilization through 863 plans, 973 plans, national science and technology support plans and other ...
