(2) remove heavier foreign material such as wheat in the wheat straw, stone;
(3) wheat straw that will remove foreign material is removed wherein dust and light weight sundries with deduster;
(4) wheat straw that will remove foreign material is sent into the boiling vessel boiling;
(5) after the importing vapour cooking finishes the steam in the boiling vessel is imported another boiling vessel;
(6) in the boiling vessel of deriving steam, charge into compressed air to authorized pressure;
(7) explosion pulping.
Equipment comprises feeding machine 1, grass-mowing machine 2, winnowing machine 3, boiling vessel A7, boiling vessel B8, vapor can 12, air pump 18; Be connected with valve 9 with appendix between the boiling vessel 7 of discharging and the boiling vessel 8 side by side; The feed cavity on two boiling vessels, 7,8 tops is connected with feeder 11 discharging opening 11-4 by conveying pipeline 10 respectively; The air inlet at middle part is connected with vapor can 12 by appendix 6 respectively; Discharging opening one side of bottom is connected with air pump 18 with valve 15,16 by appendix 13 respectively; The discharging opening bottom is connected with material receiver 21 by conveying pipeline (5) respectively; Grass feeding machine 1, grass-mowing machine 2, air classifier 3 threes are emitted on boiling vessel 7 left sides successively, and the discharging opening of grass feeding machine 1 upper end is positioned at the feed hopper top of grass-mowing machine 2; The charging aperture of air classifier 3 is connected with the discharging opening of grass-mowing machine 2 by conveying pipeline 23; The top of winnowing machine 3 and deduster 4 is connected with feeder 11 by conveying pipeline 5 respectively, and the bottom is placed ash can 22 respectively.
The central upper portion of described feeder 11 is provided with rotatable cylindrical tubular screen cloth 11-1 the feeder inner chamber is separated into feed cavity 11-2 and goes out dirt chamber 11-3, and the bottom is discharging chamber 11-4.
Described boiling vessel 7,8, place and output needs according to the paper mill can be provided with more a plurality of boiling vessels, and the discharging chamber of matching used with it feeder 11 is connected with each boiling vessel charging aperture with conveying pipeline 10 respectively; Each boiling vessel all is connected with valve 9 by appendix successively.
The invention has the beneficial effects as follows: adopt the chaffcutter method of beating the grass and need not be traditional to make wheat straw in small, broken bits, be easy to slurrying; Boiling vessel steam is imported another boiling vessel utilize energy savings again.Feeding machine is given the grass-mowing machine mechanical feed, saves manpower, all by the conveying pipeline transferring raw material, significantly reduces the pollution of dust to environment between grass-mowing machine, winnowing machine, feeder and the boiling vessel.
Air classifier, deduster and material receiver are separated the material that can not be used for making paper pulp in the raw material respectively automatically, do not enter pulp cooking process, have not only reduced pollutional load and water treatment difficulty, reduce the water treatment expense; The material of separating simultaneously can also utilize again, improves the comprehensive utilization ratio of paper making raw material.
