Straw smashing process

Abstract

The invention discloses a straw smashing process which comprises the following steps: (1) pretreatment; and (2) smashing treatment. The smashing quality problem, the smashing continuous operation problem and the problem of high smashing cutter cost are solved mainly. The smashing quality problem refers to low fermentation efficiency caused by a too large smashing size (the length and the diameter), high screening difficulty after fermentation, low efficiency, high proportion of disqualified straw screened out and waste caused by secondary repeated smashing fermentation. The smashing continuous operation problem refers to regular production pause caused by the four reasons which are plastic product winding, stone block impact, short service lives of cutters, silting resulting from too high water content of soil and straw, and motor overheating. The problem of high smashing cutter cost refers to high cost caused by a too large cutter use amount resulting from short service lives of the cutters.

Description

technical field [0001] The invention relates to the technical field of straw processing, in particular to a straw crushing process flow. Background technique [0002] The state vigorously promotes the use of biological straws to produce organic fertilizer projects, but when actually collecting straws, especially straws of greenhouse vegetables (such as peppers and eggplants), there are the following problems: [0003] 1. There are a lot of bricks and stones inside, resulting in damage to the blade due to impact during the crushing process, high tool cost and long tool change time. [0004] 2. The root of the straw is a thick woody tissue structure, and the tool loss is large when crushing, and it cannot be crushed to an acceptable size for fermentation. [0005] 3. When the water content in the straw is above 60% (mainly fresh straw or straw that cannot be pulverized in time after stacking), the screen of the equipment will be clogged, and it needs to be shut down frequen...

AI Technical Summary

Problems solved by technology

It mainly solves the quality problems of crushing, the continuous operation of crushing and the high cost of crushing tools

The quality problem of pulverization refers to the low fermentation efficiency caused by excessive pulverization size (length and diameter), the difficulty of sieving after fermentation and low efficiency, the high proportion of sieved unqualified straw, and the need for repeated pulverization and fermentation to cause waste

The problem of high cost of crushing tools refers to the high cost caused by the excessive number of tools used due to the low tool life
