Production process method for novel crop straw environment-friendly material

Abstract

The invention relates to a production process method for a novel crop straw environment-friendly material. The method comprises the following steps: crushing, drawing and crushing straw raw materials by a rotary table type wheat grass cross-cutting vertical cracking machine; feeding the raw materials into a dry-method stock cyclone cloth bag by a belt conveyor to be subjected to dust removal; conveying the raw materials into a grass washing machine; conveying the raw materials into a double-spiral rotary steam engine, heating and softening; conveying the raw materials into a heat-preservation cabin, carrying out constant-temperature heat preservation and softening; conveying the raw materials into a double-spiral thread-rolling machine, and carrying out thread-rolling treatment; carrying out sub-sectioned grinding treatment on the raw materials by three middle-concentration and high-concentration disc mills in sequence; conveying the ground raw materials into a pulp washing machine; washing and sieving pulp by a jigging sieve pressure sieve; conveying good pulp into a sand removing device, and carrying out sand removing treatment; and finally, conveying the pulp into a pulp extruder to extrude surplus water to obtain a finished product, and conveying the tail pulp into the former link and treating. The production process adopts a pure mechanical treatment machining process and any chemical auxiliary agent is not added into the whole treatment process; and pollution to the environment is not caused and the environment is effectively protected.

Description

technical field [0001] The invention relates to a production process method of a new environmental protection material of crop straws by adopting a physical mechanical method. Background technique [0002] my country is a large agricultural country, with large crop straw output, wide distribution, and many types. The straw varieties are mainly rice, wheat, cotton stalks, etc., which are valuable resources for farmers' life and agricultural development. The production of crop straw is increasing year by year, but rural straw Disposal at will and incineration are serious, bringing a series of environmental problems. [0003] Continuously improve the level of industrial utilization of straw, and use straw scientifically. Crop straw raw materials are valuable raw materials for production. my country has a long history of grass non-wood fiber pulping. The key to scientific and rational use of crop straw raw materials is to control pollution. [0004] Most straw pulp mills adopt ...

Problems solved by technology

[0004] Most straw pulp mills adopt the traditional process of pulping with "high temperature", "high pressure" and "strong alkali" alkaline pulping process. It is difficult to effectively treat the waste liquid and waste residue from straw raw material pulping. Even many small straw pulp mills discharge at will without treatment at all, thus causing serious pollution to the environment
