Straw type agricultural waste crushing and composting integral control device and method

Abstract

The invention discloses a straw type agricultural waste crushing and composting integral control device which comprises a material composting chamber, a straw crushing device, a temperature oxygen control system, a humidity control system and a discharge system, wherein a feeding hole, a measuring hole and a standby hole are formed in the material composting chamber; a groove is formed in the bottom of the material compositing chamber; the upper part of the material compositing chamber is connected with the straw crushing device; the lower part of the material compositing chamber is connectedwith a micro-pore net, a porous plate and a cold-hot air mixing chamber; the straw crushing device comprises a feeding driving motor and double mixing blades; the temperature oxygen control system comprises a temperature measurer, an oxygen measurer, a temperature oxygen cascade control system, an air blower, a hot resistance wire, an air tube, a hot air chamber, a bypass cold air valve, a rotor flowmeter and a cold-hot air mixing chamber; an air tube hole is formed beside the cold-hot air mixing chamber; a percolate discharge hole is formed in the lower part of the cold-hot air mixing chamber; the humidity control system comprises a humidity measurer, a spraying device, a straight-in single-base valve and a humidity controller; the discharge system comprises a discharge groove, a discharge driving motor, rolling wheels, a discharge hole and a push-pull type baffle plate. The invention further discloses two straw type agricultural waste crushing and composting methods of fixed value continuous control and programmed control. By adopting the device, automatic material feeding and discharge, automatic crushing and composting fermentation can be implemented in the straw type agricultural waste treatment process, automatic control on humidity, temperatures and oxygen in the composting process can be achieved, the labor and materials can be saved, meanwhile, the compositing time ofagricultural wastes can be shortened, and composting conditions can be optimized.

Description

technical field [0001] The invention relates to the technical field of agricultural waste treatment, in particular to an integrated control device and method for crushing and composting straw-like agricultural waste. Background technique [0002] Today, crop yields are increasing year by year, and more and more agricultural wastes are produced. Incineration is a common treatment method, but the resulting environmental pollution is becoming more and more serious. Therefore, returning compost to the field is highly recommended by people. . Composting is a biochemical process that uses microorganisms that exist in abundance in nature to artificially promote the conversion of biodegradable organic matter into soil that can be reduced and improved. At present, high-temperature composting technology is relatively mature, while the development of low-temperature fermentation technology applied in the northern temperate zone is currently immature and the effect is not ideal. Low t...

AI Technical Summary

Problems solved by technology

At present, high-temperature composting technology is relatively mature, while the development of low-temperature fermentation technology applied in the northern temperate zone is currently immature and the effect is not ideal

Low temperature control is difficult to meet the requirements, which affects the development of low temperature fermentation technology

It has caused the problems of untimely disposal of solid waste and excessive energy consumption, making it difficult to meet the national requirements for environmental pollution control

[0003] The composting process requires a large number of technical problems such as crushing, heat preservation, moisture retention, and oxygen supply. It takes a long time and a lot of work, and the conditions are not easy to control, and often fail to meet the technical requirements of composting.
