Problems solved by technology

At the same time, a foul odor is formed, affecting the surrounding living environment
[0005] 2. Pollution to the soil
[0008] 3. Pollution to the water environment
[0010] 4. Antibiotic pollution
[0012] In addition, some areas currently use pig manure to feed fish. After a little treatment, the pig manure is put into fish ponds, which is called "circular economy". Pathogenic bacteria, antibiotics, etc. can easily cause fish infection, become "pig dung fish", and become a huge hidden danger to human health after entering the human food chain

Embodiment 1

[0107] Take 10 tons of cow dung (with a moisture content of 70%), spread it on the drying field, and dry it under direct sunlight until the moisture content is 40%, and obtain 5 tons of dry matter, which is transported to the KJG type through a closed screw conveyor. Paddle-type dryer, which uses high-temperature water as a heat source to indirectly heat and dry livestock manure (water temperature is 60-100°C). The moisture content of dried livestock manure reaches 20%, and the mass is about 3.7 tons. Then it enters the BMS type carbonization furnace through the closed spiral conveying pipe; the temperature of the carbonization furnace is preheated to 700°C, and it starts to receive dry animal manure. After 20 minutes of carbonization treatment, it becomes black carbonization. After the charcoal is cooled to 150°C by a tubular water cooling device, it enters the vibrating screen for sieving, and the sieved material is placed in a ventilated place (with no flammables around it) ...

Embodiment 2

[0117] Take 10 tons of pig manure (moisture content 80%), crush bamboo, branches, etc. into wood chips (bamboo chips) with a diameter of 1 to 10 mm, and take 5 tons, fully mix and stir, with a total weight of 15 tons; The material is transported to the KJG paddle dryer, and the heat-conducting oil is used for indirect heating (the temperature of the heat-conducting oil is 160 degrees Celsius) to heat and dry the material, and the material is fully mixed through the rolling and stirring of the blades inside the dryer. After 25 minutes, the material is dried to a moisture content of 30%, and enters the BMS sludge carbonization furnace through a closed screw conveying pipe; the temperature of the carbonization furnace is preheated to 760°C, and the material starts to be received. After 18 minutes of carbonization treatment, it becomes Black carbide. After the charcoal is cooled to 150°C by a tubular water cooling device, it enters the vibrating screen for sieving, and the sieved ...

Abstract

The invention discloses a production method of an animal manure carbon fertilizer. Raw materials are animal manures. The production method of the animal manure carbon fertilizer comprises the following steps of: a, mixing organic granules; b, dryly granulating; c, carrying out carbonization processing; d, water-cooling; e, screening; and f, backmixing, and granulating. The animal manure carbon fertilizer is produced by adopting the animal manures such as pig manures, cow manures, sheep manures, horse manures, and the like as the raw materials and converting the organic matters contained in the animal manures into biological carbon by heating the animal manures at high temperate in a low-oxygen environment, has the characteristics of self multihole, large specific surface area, high absorbance, and the like, improves the soil ecological environment, can enhance the fertilizer utilization ratio through the characteristics of absorption and slow release, also has a soil improvement function, fertilizer synergy and higher content of fertilizer components such as nitrogen, phosphorus, potassium, and the like, and can be used by partially replacing a fertilizer; and in addition, the animal manure carbon fertilizer can be used as a slow release synergist of the fertilizer, plays a role of fixing the fertilizer and moisture, achieves the purposes of prolonging fertilizer effect and enhancing fertilizer utilization ratio.

Description

technical field [0001] The invention relates to the technical field of fertilizers and preparation methods thereof, in particular to a livestock dung charcoal fertilizer and a production method thereof. Background technique [0002] According to the data in the Agricultural Statistical Yearbook in 2005, it is estimated that the total amount of livestock and poultry manure produced in my country in 2005 reached 2.6 billion tons, of which the output of cow manure and pig manure reached 1.027 billion tons and 287 million tons respectively. However, since our country entered the 21st century, the aquaculture industry has developed rapidly, and intensification and scale have become the inevitable trend of the aquaculture industry. The environmental pollution problems caused by this are becoming more and more serious. cause serious pollution. The main environmental impacts are as follows [0003] 1. Air pollution [0004] The manure and other wastes accumulated and stored in li...
