Description

Biomass based on volume fluctuation continuously dodges quick-fried and in-situ blending equipment
Technical field
The utility model relates to composites processing technology fields, more particularly to the biomass based on volume fluctuation is continuously dodged Quick-fried and in-situ blending equipment.
Background technique
Biomass composite is the new generation of green environmental protection material that the world is booming in recent years, and primary raw material is biomass Material (such as stalk, timber, bamboo, sisal hemp and animal feather) and plastics.Biomass composite is at low cost, can replace timber And plastic products, application field constantly expand.
However the close structure of biomass, if vegetable material has using cellulose as skeleton, hemicellulose and lignin etc. are filled When the close layer structure of binder;And animal feather has the keratin as resistance hardness threadiness close made of folding Structure.Therefore it needs to open the close structure of biomass by dodging quick-fried method, increase the area of biomass and plastic contacts, mention Both high exchange frequency in the blending process, keeps biomass evenly dispersed in the plastic, enhances biomass composite with this Performance.
Dodging quick-fried is a kind of method for completing steam blasting in a very short period of time, and the existing quick-fried equipment of sudden strain of a muscle has intermittent and continuous Two kinds of formula.But it is intermittent to dodge quick-fried equipment yield lower, inefficient, be unfavorable for expanded application;And continous way dodges quick-fried equipment master It to be acted on screw rod frictional drag and generate heat and transport forward, by forming high pressure before outlet, finally spray instantaneous pressure It is quick-fried that sudden strain of a muscle is completed in rapid drawdown, but it is quick-fried also to define that biomass can only once dodge after experience once transports in exit completion, dodges quick-fried Not exclusively, it is therefore desirable to by dodge it is quick-fried after product repeatedly put into continous way repeatedly and dodge in quick-fried equipment to ensure to dodge quick-fried effect, work Sequence is cumbersome.And cellulose, keratin etc. are easy degradation in hot environment for a long time.Furthermore based on screw rod shearing rheology Continous way is dodged in quick-fried equipment, and Strong shear effect easily leads to fiber breakage, fibre length reduces, and finally influences product property.
Existing plastics/biomass composite manufacturing process mainly first dodges quick-fried biological material with the quick-fried equipment of sudden strain of a muscle, after sudden strain of a muscle is quick-fried Biological material after the techniques such as drying, drying, then add twin-screw extrude to be blended simultaneously with plastics and prepare finished product. If but this manufacturing process is lengthy and jumbled, required process equipment and auxiliary device are various, biological material dodges quick-fried equipment and blending equipment It adheres to different enterprises separately, can additionally increase the costs such as packaging, transport, preservation.It is blended in twin screw device simultaneously and equally exists life The disadvantages of substance thermal history is long, and shear strength is big, furthermore fiber is easy to spin agglomerating in Shearing Flow, and difficulty is uniformly dispersed, The mechanical property of biomass composite is eventually reduced, plastics/biomass composite expanded application is limited.
Utility model content
For the technical problems in the prior art, the purpose of this utility model is: utility model provides a kind of structure Simply, continuously the biomass based on volume fluctuation continuously dodges quick-fried and in-situ blending equipment to process.
In order to achieve the above object, the utility model adopts the following technical solution:
