Production device and preparation method of livestock manure organic fertilizer

Abstract

The invention discloses a production device and a using method of livestock manure organic fertilizer. The production device comprises a supporting frame, a propelling system, stirring blades, a stirring shaft, a heating device and a barrel, wherein a material inlet and a material outlet are formed in the barrel; the stirring shaft penetrates through the barrel; vent hole passages are formed in the stirring shaft; vent holes are formed in the stirring blades; the vent hole passages in the stirring shaft are communicated with the vent holes in the stirring blades; the barrel is provided with the heating device; the vent hole passage in one end of the stirring shaft is connected with the heating device; a transmission device is arranged on the other end of the stirring shaft; the propelling system is mutually matched with the transmission device. The using method comprises the following steps: controlling the temperature in the barrel to be 70 DEG C to 80 DEG C, fermenting livestock manure for 15 to 20 days for the first time, subsequently putting livestock manure, and fermenting for a period of 7 to 15 days. The production device of the livestock manure organic fertilizer, disclosed by the invention, has a simple structure, is convenient and practical, and is simple in operation, high in production applicability, low in production cost and small in occupation area.

Description

technical field [0001] The invention belongs to the field of fermentation equipment, and in particular relates to a production equipment of livestock and poultry manure organic fertilizer and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the great changes in the diet structure, the proportion of livestock and poultry products in the diet structure is gradually increasing. Therefore, the aquaculture industry has also developed rapidly. In the past 20 years, the average annual growth rate of my country's poultry and livestock breeding industry has been 9.9%. The rapid development of large-scale breeding industry has not only solved the human demand for meat, eggs and milk, but also brought serious environmental pollution problems. The scale of traditional free-range farming is small, and the manure produced by livestock and poultry can be used as organic fertilizer, and the waste discharge can be comprehensive...

Problems solved by technology

However, how to deal with the manure of livestock and poultry economically and efficiently has always been a difficult problem

At present, there are many kinds of treatment methods with little effect. There is no large-scale and popularized excellent equipment suitable for all kinds of farmers to deal with livestock and poultry manure in China. The existing technologies usually use the following methods to deal with livestock and poultry manure. One is to build a biogas digester to pump the concentrated feces to the biogas digester to produce biogas, which requires large investment, high maintenance and low benefit

The second is the fermentation technology. The traditional fermentation technology requires a large amount of space, a complicated process, and the addition of various substances. The process is cumbersome, time-consuming, laborious, and expensive. It is difficult for farmers to master the fermentation technology, which makes it difficult to popularize the technology.

The other is to use composting houses, composting tanks, composting towers, composting trays and other equipment for composting. The decomposing speed is slow, the odor emitted is not reduced, and the continuous production cycle is long. This method is inefficient and labor-intensive. Especially For large pig farms, this method is even more unfeasible
