Abstract
The invention discloses a straw biomass crushing and molding method, comprising the following steps: firstly, feeding straw biomass to a crusher to crush, and then feeding the crushed material to a molding machine to be molded by virtue of extrusion of an extrusion roll; leading a hot air source; firstly, heating the extrusion roll and the crushed material by using the hot air generated by a hot air source so as to be conveniently molded, and then feeding into the crusher to dry the material, and blowing the qualified material to the molding machine after screening the crushed material. By adopting the straw biomass crushing and molding method, firstly, the extrusion roll of a hot air heating molding machine is used, and then hot flow is fed to the crusher, so that the crushed material is dried and screened, the qualified crushed material is fed to the molding machine by the hot air to be molded. Thus, on one hand, loss of a fine material is avoided, and on the other hand, crushing of the material when drying is achieved. Therefore, the crushing efficiency and the quality of the crushed material are improved.
Description
Technical field
The present invention relates to stalk biomass machine-shaping field, a kind of stalk biomass pulverizes forming method specifically.
Background technology
Biomass comprise several large classes such as organism (as plant, animal and movement thereof), rubbish and the organic waste water that plant generated by photosynthesis.The energy sources of biomass is in the sun, so biomass energy is the one of sun power.Biomass are the topmost resorber of sun power and holder, and biomass can be accumulated sun power by photosynthesis, are stored in organism, extensively utilize biomass-making for granulated feed, fuel etc. in prior art.
Stalk biomass must first be pulverized when utilizing, then shaping.Existing disintegrating apparatus is simple utilize mechanical force by crushed stalk, the efficiency of pulverizing can be caused so not high because stalk biomass water ratio before pulverizing is high, and crushing effect can be made bad, material after pulverizing is different in size, and fine granular materials wherein also likely can lose the waste causing raw material.And existing molding device to be the simple bulk that is pressed into by stalk biomass crushed material be convenient to store or transport, or be pressed into the granulation that strip is convenient to the later stage.But because crushed material may exist the high problem of water ratio, the biomass after shaping likely can be mouldy, rotten very soon, not only affects surrounding environment, nor can utilize well.
Summary of the invention
For solving the problem that stalk biomass of the prior art easily loses in the easy corruption of undesirable, the shaping rear material of the crushing effect caused because material water ratio is high pulverizing shaping middle existence and fine crushing material, the invention provides a kind of stalk biomass and pulverizing forming method.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of stalk biomass pulverizes forming method, stalk biomass is first sent in pulverizer and pulverizes, then the material after pulverizing is sent in forming machine and relies on extrusion roll extrusion molding, introduce hot air source, extrusion roll and crushed material first heat so that shaping by the hot blast that hot air source produces, and then be sent in pulverizer drying is carried out to material, and to after the material screening crushed, qualified material is blowed in forming machine.
In pulverizer, blast air-flow, realized the screening of crushing rear material by air-flow and the mixed mixed airflow of hot blast and send screening qualified material into extrusion molding in forming machine.
Described air-flow and hot blast enter to blow afloat material by pulverizer bottom.
Beneficial effect: the present invention compared with prior art, has the following advantages:
1) first the material pulverized is screened by air-flow (hot blast or mixed airflow), pulverizing qualified material, to be sent to forming machine by hot blast shaping, avoid the loss of fine crushing material on the one hand, the pulverizing limit, limit also achieving material is on the other hand dry, thus improves the efficiency of pulverizing and the quality of crushing rear material;
2) extrusion roll of forming machine is adopted Hot-blast Heating by the present invention, the hot blast after heating is made to carry out UTILIZATION OF VESIDUAL HEAT IN like this, pulverizer inner drying material is sent to by these hot blasts, and material is screened and carries, make pulverizing and shaping combination, preventing by pulverizing the problem transferring to loss of material, power loss and the contaminated sites caused in molding procedure, also improving working (machining) efficiency simultaneously;
3) the present invention can by controlling air-flow (hot blast or mixed airflow) pressure in pulverizer thus size, the weight of qualified material are pulverized in adjustment, when needs small size material carries out shaping, suitably can turn the pressure of air-flow down, otherwise, then tune up the pressure of air-flow.This method being adjusted crushing rear material size by adjustment stream pressure, is not only controlled accurately with easy, and makes the material qualification rate after pulverizing higher.
Embodiment
Below in conjunction with specific embodiment, the present invention is further elaborated.
A kind of stalk biomass pulverizes forming method, stalk biomass is first sent in pulverizer and pulverizes, then the material after pulverizing is sent in forming machine and relies on extrusion roll extrusion molding, introduce hot air source, extrusion roll and crushed material first heat so that shaping by the hot blast that hot air source produces, and then be sent in pulverizer drying is carried out to material, and to after the material screening crushed, qualified material is blowed in forming machine.
In pulverizer, blast air-flow, realized the screening of crushing rear material by air-flow and the mixed mixed airflow of hot blast and send screening qualified material into extrusion molding in forming machine.
Described air-flow and hot blast enter to blow afloat material by pulverizer bottom, material so also can be made impractical and to be loosely distributed in pulverizer, thus more easily by the blade of pulverizer or blade smash, improve crush efficiency and crushing effect.
In the present invention, can by regulating the flow velocity of hot blast, fan stream thus realizing the control to pulverizing rear qualified material particle diameter, if particle diameter is greater than the particle diameter of qualified material, its weight must be greater than the weight of qualified material, therefore, can not blow in forming machine shaping by mixed air-flow.
Claims (3)
1. a stalk biomass pulverizes forming method, stalk biomass is first sent in pulverizer and pulverizes, then the material after pulverizing is sent in forming machine and relies on extrusion roll extrusion molding, it is characterized in that: introduce hot air source, extrusion roll first heats so that shaping by the hot blast that hot air source produces, then the hot blast that after having heated extrusion roll, temperature reduces is sent in pulverizer again and carries out drying to material, and blow qualified material in forming machine to after the material screening crushed, and adjusted the size pulverizing qualified material by the flow controlling hot blast.
2. a kind of stalk biomass according to claim 1 pulverizes forming method, it is characterized in that: in pulverizer, blast air-flow, realized the screening of crushing rear material by air-flow and the mixed mixed airflow of hot blast and send screening qualified material into extrusion molding in forming machine.
