Description
Technical field
The present invention relates to the agricultural crop straw environmental friendly material manufacturing technique method adopting physical mechanical method for making.
Background technology
China is a large agricultural country, agricultural crop straw output is large, distribution is wide, kind is many, and stalk kind, based on paddy rice, wheat, cotton stalk etc., is the precious resources of life of farmers and agricultural development, agricultural crop straw generation increases year by year, straw from village is arbitrarily abandoned, and burns phenomenon seriously, brings a series of environmental problem.
Improve constantly straw industrialization and utilize level, scientific utilization stalk.Agricultural crop straw raw material is valuable raw materials for production, and China's grass class non-wood-fiber slurrying is with a long history, scientific and reasonablely utilizes agricultural crop straw raw material, and its key is pollution administration problem.
The Conventional processing methods that most of straw pulp mill adopts, mostly the soda pulping process technique adopting wood pulp " high temperature ", " high pressure ", " highly basic ", stalk slurrying waste liquid out, waste residue, be difficult to effective process, even many small straw plants just do not process discharge arbitrarily, therefore cause severe contamination to environment.
Lumber fibre such as the conifer fiber of needlebush and the willow fibrid of leaf wood are all paper industry main raw materials.The wood raw material of China's papermaking lacks very much, but the output of Chinese paper and paperboard and consumption figure but all rank first in the world.China all must spend more than the 100 hundred million dollars of import paper making raw material-wood pulp fibres occupying foreign exchange volume the 3rd every year.
And the agricultural crop straw of China is very abundant, it is the first in the world.There is more than 700,000,000 ton of agricultural crop straw every year, wherein have more than 500,000,000 ton to be applicable to doing paper making raw material.If extract crop branch fiber by the new technology of " with careless Dai Mu ", " moulding with grass generation " to be used for using, just greatly can alleviate the raw material problem in short supply of country, and the production cost of enterprise significantly can reduce, profit just can get a promotion.If the stalk amount of Chinese half " with careless Dai Mu ", " moulding with grass generation " new technology are extracted fiber and be used for papermaking, just can replace the primary wood raw material of global 65%, thus conserve forests, improve the ecological environment that the earth goes from bad to worse.
Summary of the invention
The object of the present invention is to provide the manufacturing technique method of agricultural crop straw environmental friendly material, it is the agricultural crop straw environmental friendly material production technology adopting physical mechanical method for making.
Technical scheme of the present invention is:
The manufacturing technique method of agricultural crop straw environmental friendly material, is characterized in that: the method step comprises:
(1), by rotating disc type wheat straw crosscut lobe machine, stalk is pulverized, wire drawing size degradation;
(2), by belt conveyor raw material is sent into dry raw material preparation whirlwind bag-type dust, to remove the silt, impurity etc. in raw material; Then, then raw material is sent into grass washing machine, to remove the impurity adulterated in raw material;
(3), raw material is sent to self-emptying storehouse; Thermoplastic process is carried out through double helix steam engine; Sending into belt thermal insulation barn again, to carry out constant temperature insulation softening, so that following process process;
(4), by the raw material feeding double helix thread rolling machine after softening carry out thread rolling process, make the raw material after process reach corresponding technic index;
(5), by the raw material after thread rolling more successively in three high dense mill carry out the process of segmentation defibrination, make raw material carry out fine processing from corase grind to fine grinding;
(6) raw material, after defibrination process, then send into wash engine, slurry is cleared up further;
(7), through vanning pressurized screen, washing and sieving is carried out to slurry again; Good slurry enters next workshop section, enters desander and carries out desanding process; Finally entering press master again extrudes unnecessary moisture, is finished product; Tail slurry is then delivered to a link again and is processed.
Wherein, the dense grinding machine of senior middle school adopted in described step (5) carries out segment processing, can process stalk from the aspect such as grinding machine abrasive disc material (steel mill, stone mill), electric current (30-50mA), feed gap (0.2-2mm), material concentration (2%-8%), to determine concrete technological process.
Treatment effect in each step of described method can control from aspects such as beating degree (15SR), weight in wet base (3g), fracture length (2.2km), ring pressure (9.1N*m/g), foldings (1), to guarantee that product meets corrugated paper and copies and join.
Carry out joining copying sample to stalk mechanical fiber and state's useless, U.S. useless (by 1:1:8,2:1:7 equal proportion), join high-strength corrugated paper to determine that stalk mechanical fiber can be copied.
Described rotating disc type wheat straw crosscut lobe machine, be carry out the longitudinal wire drawing of transversely cutting to raw material to pulverize, its major advantage is that the least possible destroy crops straw environment protection new material reaches the raw material refinement pulverizing of expectation, is convenient to next link and processes.
Described dry raw material preparation whirlwind bag-type dust, is that the fine particle produced after pulverizing the silt impurity in raw material and raw material carries out cleaning eliminating by wind-force, reaches raw material cleaning purpose.
Described grass washing machine, is cleared up by the intractable dust being difficult to be removed by wind-force of clear water to raw material surface attachment, reaches raw material cleaning purpose.
Described self-emptying storehouse is the transferring equipment raw material after clean being sent to next link.
Described double helix steam engine, is by Steam Heating, stalk is softened, is rotated and raw material is heated evenly, improve pre-heat effect by double helix.
Described belt thermal insulation barn carries out isothermal holding to the raw material of heating, transmitted and avoid raw material to overstock on the one hand, ensure on the other hand to be heated evenly by belt.
Described twin-screw thread rolling machine carries out thread rolling process to raw material, attaches refining effect in addition, carries out preliminary treatment early stage, impel fiber sub-wire, brooming to raw material.
The invention has the advantages that: the present invention changes the processing mode of stalk, raw material first carries out defibrination by Steam Heating, boiling after softening again, fundamentally can be improved the quality index of product by the raw material of softening post processing.Water circulation uses in process of production, does not produce black liquor, nonhazardous material in waste water, qualified discharge after wastewater treatment equipment.Keep not making fibre damage hinder in slurrying purification process, pulp strength is high, is applicable to the requirement of production high-quality paper completely.The present invention adopts mechanical treatment processing technology, does not add any chemical assistant in whole processing procedure, to environment without any pollution, effectively protects environment.
