Description

A kind of have cutter and cut, hammer into shape and cut and tear the stalk crasher of cutting function

Technical field

The utility model is applicable to the production of getting the raw materials ready of industries such as papermaking straw pulp, biomass power generation, high value biogas, bio-natural gas, stalk cellulose ethanol, relates generally to a kind of stalk and tears tearing mill pulverizer.

Background technology

At present domestic in the crushed stalk apparatus and process, what generally adopt is rotor formula, disc type chaffcutter.

Rotor formula chaffcutter: incision principle is simple, namely macro-axis install three knife plate as moving knife, the material inlet place installs one quiet cutter, sending into the stalk cut-out, the raw material after the processing remains tubulose (section shape) by the macro-axis rotation.Knife plate causes the product uniformity of getting the raw materials ready poor through 2-3 hours blade blunts, can not satisfy the requirement of subsequent technique.And per tour subsistence level reconditioning blade once, dismounting, installs very inconveniently, also will be equipped with knife grinding equipment and operating personnel.

The disc type chaffcutter: cutting mode is at macro-axis bracket panel to be installed, at bracket panel the hammer cutter is installed, carrying stalk to hammer into shape by rotor cuts, cutting mode is the same with the rotor formula single, when the raw material water content is big, perhaps toughness strong (as straw), hardness big (as cotton stalk) time, production capacity reduces significantly, the uniformity is poor, is difficult to satisfy the needs of ordinary production.

These two kinds of equipment incision principles are simple, do not satisfy the needs of producing, and mainly show as:

1, the product of getting the raw materials ready after the cutting is tubulose, section shape and inhomogeneous, is difficult to reach the post-order process requirement; 2, to stalk humidity bad adaptability, when the stalk water content was big, cutting effect was poor, and output reduces significantly; 3, to the bad adaptability of stalk kind, the raw material strong to toughness, that hardness is big is difficult to reach the requirement of subsequent technique; 4, the product of getting the raw materials ready is inhomogeneous; 5, production capacity instability.

In sum, more than two kinds of technologies, the product of getting the raw materials ready after the processing remains tubulose (section shape).And the uniformity is poor, is difficult to satisfy the requirement of follow-up boiling (papermaking), fermentation (bio-natural gas, high value biogas and stalk cellulose ethanol) technology.Prolong the time of boiling, fermentation, reduced operating efficiency, increased electricity, vapour, the consumption of alkali and the input of other auxiliary materials, strengthened production cost.

The utility model content

The purpose of this utility model provides that a kind of energy consumption is low, efficient is high, adaptablely have cutter and cut, hammer into shape and cut and tear the stalk crasher of cutting function, the stalk that can be widely used in papermaking straw pulp, biomass power generation, bio-natural gas, high value biogas, the stalk cellulose ethanol industry technology of getting the raw materials ready.

The purpose of this utility model can adopt following technical scheme to realize:

Described in the utility model have cutter and cut, the stalk crasher of cutting function is cut and torn to hammer, its fuselage is whole to be taper, the fuselage front upper part is charging aperture, the fuselage rear lower is pulp cutlet, main shaft is arranged in the fuselage, inlay nog plate on the fuselage inwall, two ends are provided for the bearing block of fixed main shaft, characteristics of the present utility model are that three groups of workpieces that job specification is different are installed from the charging aperture to the pulp cutlet on main shaft successively, are respectively for the cutter of cutting stalk and cut parts, the hammer that the relatively large stalk of volume is carried out secondary cut is cut parts and tearing of profoundly cutting of stalk is cut parts.

Described cutter is cut parts and is rectangle, puts the first edge on a knife or a pair of scissors, and is installed in front-end of spindle.

It is rectangle tabular (bar) that described hammer is cut parts, is installed on cutter and cuts on the main shaft at parts rear portion.

Describedly tear that to cut parts be microscler isosceles trapezoid foliaceous, be installed on hammer and cut on the main shaft at parts rear portion.

The front portion of tearing tearing mill pulverizer at stalk described in the utility model disposes belt conveyor etc., and has raw material to carry the storehouse; The rear portion is provided with finished product raw material gatherer, thereby realizes the mechanized operation operation.

The utility model is to produce various cutting method at main shaft in dynamically, thereby guarantees the uniformity of stalk cutting and stablizing of production capacity, and toughness, hardness, the humidity of stalk is not had specific (special) requirements.The technology forming process is to enter in the cutting process at stalk, cuts, hammers into shape to cut and tear and cut multiple cutting mode and once finish through cutter.

It is cutting every cut-in without ball in rotating at a high speed that cutter described in the utility model is cut parts, and blade is not easy to wear.It is secondary cut that the relatively large stalk of volume is carried out that hammer is cut parts.Tearing and cutting parts is to profoundly the cutting of stalk, and by leaf cutter and nog plate stalk is torn and is cut to puffy.The utility model is strong to all kinds of adaptability to raw material, can both accomplish effective size degradation to various types of stalk, bark, branch, reed, finished product raw material uniformity height, undesired impurities good separating effect.Can realize mechanized operation, have that energy consumption is low, efficient is high, production capacity is stable, save manpower, the characteristics of high safety.
