Problems solved by technology

However, the currently used fermentation devices generally directly add the stirred animal manure to the ventilated mesh crawler of the fermentation device, and ferment while conveying under the slow running of the mesh crawler. However, based on especially fresh animal manure, the water content is high. , the water content of some fresh animal manure is as high as 80%. Based on the fermentation device, air-assisted fermentation is generally used. Under high temperature, animal manure will stick and harden to block the mesh track, and the fermentation efficiency will decrease over time; at the same time, the use of high temperature and long-term fermentation is harmful. The large increase in gas emissions is not conducive to meeting the current environmental protection requirements

Embodiment Construction

[0020] Such as figure 1 As shown, a front-stage fermentation device for animal manure organic fertilizer includes a device body 1, in which a first funnel-shaped centrifugal table 11, a second funnel-shaped centrifugal table 8, and a third funnel are distributed sequentially from top to bottom in the device body 1. Shape centrifugal table 6; Of course, the number of layers of funnel-shaped centrifugal table can be selected according to needs; The above-mentioned three funnel-shaped centrifugal tables all include a bottom plate 11-2 and a funnel side plate; the side plate of the funnel is provided with a number of ventilation pores 11-1, and the ventilation pores on the side plate of the funnel are from bottom to top, Opening inclined from the inside to the outside is mainly to prevent clogging caused by the centrifugation process and to promote the flow trend of the bottom-up air flow to the outer periphery. The inclination of the funnel side plate of the second funnel-shaped...

Abstract

The invention discloses a front-section fermentation device for preparation of an animal waste organic fertilizer. The front-section fermentation device comprises a device body, wherein funnel-shapedcentrifugal tables are distributed in the device body; each of the funnel-shaped centrifugal tables comprises a bottom plate and funnel side plates; a plurality of small ventilation holes are formed in the funnel side plates; an air inlet is formed below the funnel-shaped centrifugal tables; a suction opening and a feeding opening are formed above the middle parts of the funnel-shaped centrifugaltables; and the funnel-shaped centrifugal tables are bonded on a driving rotating shaft and rotate along with the driving rotating shaft. The front-section fermentation device provided by the invention is good in the effect of removing excess water and allows bacterial propagation to be fast.

Description

technical field [0001] The invention relates to the technical field of animal manure organic fertilizer fermentation, in particular to a front-stage fermentation device of animal manure organic fertilizer. Background technique [0002] At present, it is very common to treat animal manure with organic fertilizer. When aerobic fermentation is carried out, the strain is usually stirred first, and then transferred to the fermentation device through a conveyor. Generally, organic fertilizer can be obtained after about 24 hours of fermentation. However, the currently used fermentation devices generally directly add the stirred animal manure to the ventilated mesh crawler of the fermentation device, and ferment while conveying under the slow running of the mesh crawler. However, based on especially fresh animal manure, the water content is high. , the water content of some fresh animal manure is as high as 80%. Based on the fermentation device, air-assisted fermentation is generall...
