Abstract

The invention discloses a technology for producing an organic fertilizer from pig manures. The technology comprises raw material selection and matching, drying and disinfection, ingredient mixing, granulating, cooling and screening, metering and sealing, and finished product warehousing. The technology specifically comprises: fermenting the raw materials according to the ratio, after fermentation putting the raw materials in a semi-wet material pulverizer for crushing, then adding nitrogen, phosphorous and potassium elements to make the mineral elements reach a needed standard, then stirring by a stirrer, placing in a comminutor for granulating, taking out and drying, sieving via a screening machine, packaging qualified products and returning unqualified products to the comminutor for granulating. The technology overcomes the disadvantages of the prior art; the fermented product is good in drying efficiency and good in deodorizing effect and fly eradication effect; and the technology is low in energy consumption and short in production time.

Description

A kind of by pig manure production fertilizer technique

Technical field

The present invention relates to the organic fertilizer production technical field, specifically belong to a kind of and produce fertilizer technique with pig manure.

Background technology

Have now in the northern area of China organic fertilizer production as moisture as raw materials such as pig manure, chicken manure, cow dungs higher, production plant periphery difficulty have controlled material as auxiliary material supplies such as sawdusts, bring the drying efficiency of tunning low, deodorizing, effect of killing flies be bad, high, the consuming time length of energy consumption while producing qualified organic fertilizer product.

Summary of the invention

The purpose of this invention is to provide and a kind ofly with pig manure, produced fertilizer technique, overcome the deficiencies in the prior art, the tunning drying efficiency is high, and deodorizing, effect of killing flies is good, the low production time of energy consumption is shorter.

The technical solution used in the present invention is as follows:

A kind of by pig manure production fertilizer technique; comprise raw material choice, dry sterilization, batching mixing, granulation, cooling, screening, metering sealing and finished product warehouse-in; described raw material is fermented by proportioning; entering half wet stock pulverizer after fermentation is pulverized; then add nitrogen, phosphorus, potassium element; make contained mineral element reach required standard; then there is stirrer to be stirred; enter again granulation mechanism particle; post-drying out; by sieve apparatus, sieve, qualified product are packed, and the underproof tablets press that returns carries out granulation.

200 kilograms+RW of described raw material pig manure 800 kilograms+bacterium slag microbial inoculum, 100 grams.

Described proportioning raw materials is carried out the bar heap as required, and bar heap length is not limit, and 2 meters of width, 1 meter of height, when bar is piled, need to successively evenly be stacked material.

Described stirrer stirs the bar heap, and after temperature is raised to more than 60 degree, at interval of turning in 4-5 days once, 60 degree are packed up the bar heap to get final product after 15 days with top fermentation.

The fineness of described raw material should be arranged in pairs or groups as follows: 80-60 purpose raw material accounts for 30%-40%, and 60 orders account for 30% to the raw material of diameter 1.00mm, and the small-particle of diameter 1.00-2.00mm accounts for 30%-35%.

Compared with the prior art, beneficial effect of the present invention is as follows:

Tunning drying efficiency of the present invention is high, and deodorizing, effect of killing flies are good, the low production time of energy consumption is shorter.

Embodiment

A kind of by pig manure production fertilizer technique, comprise that raw material choice, dry sterilization, batching mixing, granulation, 1 cooling, screening, metering are sealed and the finished product warehouse-in, raw material is fermented by proportioning, 200 kilograms+RW of 800 kilograms+bacterium of raw material pig manure slag microbial inoculum, 100 grams.Proportioning raw materials is carried out the bar heap as required, and bar heap length is not limit, and 2 meters of width, 1 meter of height, when bar is piled, need to successively evenly be stacked material.Stirrer stirs the bar heap, and after temperature is raised to more than 60 degree, at interval of turning in 4-5 days once, 60 degree are packed up the bar heap to get final product after 15 days with top fermentation.Entering half wet stock pulverizer after fermentation is pulverized; then add nitrogen, phosphorus, potassium element; make contained mineral element reach required standard; then there is stirrer to be stirred; enter granulation mechanism particle, out post-drying, sieve by sieve apparatus again; qualified product are packed, and the underproof tablets press that returns carries out granulation.The fineness of raw material should be arranged in pairs or groups as follows: 80-60 purpose raw material accounts for 30%-40%, and 60 orders account for 30% to the raw material of diameter 1.00mm, and the small-particle of diameter 1.00-2.00mm accounts for 30%-35%.The material fineness is higher, and viscosity is just better, and the particle surface smooth finish after granulation is also just higher.But the problems such as in process of production, the use of superproportional high fineness material, be prone to because viscosity is excessively good and cause particle excessive, and particle is irregular.
