Organic straw manure fermentation device

Abstract

The invention discloses an organic straw manure fermentation device used for straw processing. The organic straw manure fermentation device comprises a fermentation tank, wherein a feeding hole and apressure relief air outlet are formed in the top of the fermentation tank; a water seepage plate is arranged at the bottom of the fermentation tank; a bottom water tank is arranged at the bottom of the water seepage plate; a motor is arranged on the top of the fermentation tank; the motor is in transmission connection with a stirring shaft arranged in the fermentation tank by virtue of a coupling;stirring blades are arranged on the stirring shaft; the pressure relief air outlet is connected with a gas cylinder through a pressure relief air outlet pipe; and a pressure relief valve is arrangedon the pressure relief air outlet pipe. The organic straw manure fermentation device disclosed by the invention is compact in structure and convenient to use, the production operation of fermenting the organic straw manure can be rapidly realized, the organic straw manure fermentation quality is ensured, excessive moisture produced by straw fermentation is subjected to osmotic dehydration, and gases produced by straw fermentation are decompressed, discharged and collected by virtue of the pressure relief air outlet pipe and the gas cylinder, the condition that continuous fermentation of the straws is inhibited by fermented gases is avoided, and the fermentation speed is further increased.

Description

technical field [0001] The invention relates to the field of straw processing, in particular to a straw organic fertilizer fermentation device. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Straw fertilizer is rich in organic matter, balanced in nitrogen, phosphorus and potassium, and contains various trace elements. It is a common fertilizer suitable for various crops and soils. It has the remarkable effect of improving product quality and increasing output. Straw organic fertilizer production needs to ferment straw materials. The existing straw organic fertilizer fermentation device has a slow fermentation speed. For water, methane, carbon dioxide, hydrogen sulfide (smelly Fermentation water leads to high humidity of fermented straw materials, which affects the fermentation speed, and even causes straw rot to affect the fermentation quality of straw organic fertilizer. Methane, carbon dioxide, hydrogen sulfide (odo...
