Quick drying and fermenting device for livestock and poultry faeces

Abstract

The invention relates to a quick drying and fermenting device for livestock and poultry faeces. The quick drying and fermenting device comprises a machine frame, a first spiral transmission mechanism, a horizontal tank body, a supporting mechanism which is used for supporting the tank body, a first driving mechanism which is used for driving the tank body to rotate circumferentially, and an air inlet pipe which is used for feeding hot air into the tank body to dry materials; the first spiral transmission mechanism comprises a transmission cylinder which is arranged in the tank body in a penetrating manner in the axial direction; a spiral shaft is arranged in the transmission cylinder; one end of the spiral shaft is driven to rotate through a second driving mechanism; a first spiral blade and a second spiral blade which have opposite spiral directions are connected in series and are arranged on the spiral shaft; a feeding opening which is positioned outside the tank body is formed in one end of the transmission cylinder; a material falling opening which is positioned in the tank body is formed in the lower wall, corresponding to the connecting position of the first spiral blade and the second spiral blade, at one end of the tank body, of the transmission cylinder; a material returning opening which is positioned in the tank body is formed in the position, at the other end of the tank body, of the transmission cylinder; a material discharging opening which is positioned outside the tank body is formed in the other end of the transmission cylinder; a second spiral transmission mechanism which is used for conveying the materials in the tank body to the material returning opening is arranged on the inner wall of the tank body.

Description

technical field [0001] The invention relates to the technical field of fermentation devices, in particular to a rapid drying and fermentation device for livestock and poultry manure. Background technique [0002] Animal manure is a cheap compound, which contains many chemical components such as nitrogen, phosphoric acid, and calcium. It can be fermented into high-grade and high-quality organic fertilizers or further into organic and inorganic biological formula fertilizers. Massive development of industrial production of bio-organic fertilizers can not only effectively turn waste into wealth, but also avoid and control the increasingly serious environmental pollution through the processing of animal manure to add value. Fertilizers fermented from animal manure are better at feeding the soil than other industrial synthetic fertilizers. [0003] There are two types of traditional fermentation tanks in which stirring, reaction, drying, and feeding and discharging are carried o...

AI Technical Summary

Problems solved by technology

[0003] There are two types of traditional fermentation tanks in which stirring, reaction, drying, and feeding and discharging are carried out simultaneously. One is a vertical propeller stirring fermenter. The installed pipeline does not need to be disassembled frequently. The disadvantage is that the motor of the propeller stirring mechanism has high energy consumption. The stirring rod must be thick and long to adapt to the high tank body and large diameter. Moreover, the stirring rod has a large swing due to excessive torque. , the wear is serious, the sealing ring between the stirring shaft and the sealing cover is easy to be damaged, and it is very easy to cause leakage; the other type is a horizontal rotating fermenter with supporting wheels, the tank body can be rotated in a circumferential direction, and the tank body can be rotated by the rotation of the tank body. The material is picked up and dropped, and the sealing covers at both ends of the tank body do not move. The advantage is that the volume of the tank body can be enlarged, and the power of the motor driving the tank body can be small. The disadvantage is that the materials at both ends of the tank body are not mixed uniformly.

In addition, regardless of the vertical propeller stirring fermenter or the horizontal supporting wheel rotating fermenter, most of them need to add fermentation auxiliary materials for fermentation, and the material is not dried uniformly in the tank, which seriously affects the fermentation effect of the material; and it is difficult to use when feeding Most of the feeding methods of continuous feeding or semi-feeding can only use batch feeding, and the production efficiency is low
