Abstract

The invention discloses a stirring shaft of a device for rapidly fermenting and curing livestock manure and corn straws. In order to improve the stirring effect of the existing livestock and poultry manure organic fertilizer fermentation equipment, the fermentation time of the organic fertilizer is reduced, and the production effect is improved. The invention is provided with a plurality of blades with different sizes and spiral directions on the rotating shaft, wherein the spiral directions of the large blade and the small blade are opposite, so that the materials are overturned for a plurality of times in the stirring process, the stirring times and the stirring time are increased, and the stirring effect is improved. In addition, the rotary joint is installed at the front end of the rotating shaft, the stirring shaft and the supporting rod are provided with air holes, hot air is introduced in the stirring process, so that the temperature of the material can be rapidly increased, and oxygen is provided for the zymocyte.

Description

Stirring shaft of livestock manure and corn straw rapid fermentation curing equipment

The technical field is as follows:

the invention relates to the field of stirring equipment, in particular to a stirring shaft of livestock and poultry manure fermentation equipment, which is provided with two multi-section helical blades for introducing hot gas in the middle.

Background art:

present animal manure treatment facility is mostly horizontal spiral band mixer, arranges double-deck helical blade on the transmission main shaft of mixer, and inside spiral is carried the material to the outside, and outside spiral is with the material to inside gathering. The materials form a low-power high-efficiency mixing environment under the convection motion of the double-layer spiral belt. The inner and outer diameter screws arranged on the stirring shaft drive materials in the barrel body, so that the stirrer can turn the materials in the barrel body to the maximum extent. When the stirring device works, the inner spiral drives the material close to the axis to rotate in the axis direction, the axial direction is pushed from the inside to the two sides, the outer spiral drives the material close to the barrel wall to rotate in the axis direction, the axial direction is pushed from the two sides to the inside, and the mixed material can be uniformly mixed in a short time. However, due to the characteristics of high viscosity and high density of the livestock and poultry manure, the traditional continuous helical blade has relatively large resistance in the stirring process, and the requirement of the fermentation of the livestock and poultry manure on a large amount of oxygen cannot be met in the stirring process

The invention content is as follows:

the invention aims to solve the problems that in the processing of organic fertilizers, the material stirring efficiency is higher, so that fermentation bacteria and the livestock manure are more fully mixed and contacted, the supply of oxygen is increased, the fermentation function of the fermentation bacteria is exerted to the maximum extent, the fermentation time is shortened, and the fermentation efficiency is improved. In order to achieve the purpose, the invention adopts the technical scheme that:

a stirring shaft of livestock and poultry manure and corn straw rapid fermentation curing equipment mainly comprises: the stirring shaft is provided with a plurality of groups of small vent holes, 8 round pipe extension rods are welded on the stirring shaft, vent holes are also arranged on the round pipe extension rods, the round pipe extension rods are connected with a plurality of sections of helical blades with two different types, and the shaft head at the transmission end of the stirring shaft is hollow and is connected with the rotating head.

Advantageous effects

The invention can provide uniform oxygen supply for the fermentation process, can realize higher automation degree of equipment and promote the fermentation process.

Detailed Description

The invention is further illustrated by the following figures and examples.

A stirring shaft of a device for rapidly fermenting and curing livestock manure and corn straws comprises a stirring shaft 1, a helical blade 2, a helical blade 3, a rotary joint 4 and a circular pipe connecting rod 5 as shown in figure 1. Wherein helical blade 2 and helical blade 3, the external diameter variation in size, spiral opposite direction, animal manure is stirring the in-process, receives the effect of the different power of two kinds of directions, makes the material constantly advance to roll and break up, makes material and zymophyte fully react. Due to the fact that the density of the livestock and poultry manure is high, the broken spiral blades are adopted for stirring, and therefore the power required by the material moving type which is the same as that of the continuous spiral blades is relatively low.

Because the fermentation process requirement of fertilizer, the supply of oxygen is required, so be equipped with rotary joint 4 at the front end of (mixing) shaft 1, squeeze into rotary joint 4 through air pump or fan, rotary joint 4 is under the driven prerequisite of noninterference, lets in the air (mixing) shaft 1, and the rethread rotary joint 4 and pipe connect the pole 5 on the little air vent squeeze into in the stirred vessel, provide oxygen for the zymocyte.
