Abstract
The invention relates to a biomass material hot pressing die, in particular to a hot pressing die, a die cavity of which comprises a discharging section and a splayed extruding section from the inlet end to the outlet end, the axle line of the splayed extruding section is coincident with that of the discharging section, the splayed extruding section gradually reduces from external caliber to internal caliber, and calibers of all parts of the discharging section are consistent. The splayed extruding section leads biomass material to more easily enter the die cavity to realize the extrusion, and the calibers of all parts of the discharging section are consistent, therefore, the extrusion force of the biomass material is reduced during the extrusion, the discharging efficiency of the material is improved, the abrasion between the material and the die cavity is decreased, the service life of the die is prolonged, and the processing cost of the biomass material is lowered.
Description
Technical field
The present invention relates to a kind of hot pressing die, relate in particular to a kind of with biological material compression forming such as woody, draft, shrub so that the biomass material hot pressing die of transportation and storage.
Background technology
It is raw material that biological material is meant discarded solid-state with woody, draft and shrub etc., earlier these raw material is processed into loose condition (of surface), will become available material after its compression forming then.Because characteristics such as the living beings raw material have aboundresources, cost is low and renewable are subjected to using widely.But its raw material generally have the shortcoming that volume is big, be loose condition (of surface), so bring very big difficulty to its storage, transportation, cost height not only, and loss is big in storage, transportation, so before it is utilized, must compress it, reduce its volume as far as possible, could realize the maximum utilization of resource at lower cost.
Now that the general employing of biological material compression forming is hot-forming, earlier carry out helical feed by screw rod, cooperation by screw rod and die cavity realizes the screw rod extrusion modling in the die cavity of mould then, in order better to realize the compression forming quality, generally establish solenoid tube, realize the electromagnetism heating by AC power at die coat.Traditional theory of extruding is thought, the extruding degree that material is subjected in die cavity is big more, its surface is smooth more, compactness is big more, so its die cavity of traditional moulds is generally contraction-like, be that its outlet bore is less than its import bore, but in real process, because the depth of thread that screw rod stretches in the die cavity is generally shorter, is generally 30cm between 50cm, so its power conduction distance is shorter, normal pressure fails to import into the discharging section in the film chamber in the extrusion process, event fails to realize extruding, and is little to its compactness influence, and owing to bore dwindles gradually, in the extrusion of material, need bigger extruding force material could be extruded, so not only influence discharging efficient, and cause the friction of material and die cavity to increase, the loss of die cavity improves, reduce the service life of mould, also improved the processing cost of biological material simultaneously.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of Forming Quality that does not promptly influence biological material, can improve material discharging efficient again, improves the biomass material hot pressing die of die life.
Technical scheme of the present invention is: film of the present invention chamber comprises extruded segment and the discharging section along arrival end to the port of export, the dead in line of extruded segment and discharging section, the splayed shape that extruded segment reduces gradually for bore from outside to inside, the bore at each position of discharging section is unanimity.
The cross sectional shape of die cavity can be circular, square, rhombus, hexagon.
The interior bore of the bore of discharging section and extruded segment is consistent.
Extruded segment of the present invention is the splayed shape, biological material can easier be entered realize extruding in the die cavity, each position bore unanimity of its discharging section, extruding force is reduced in the discharging process of biological material like this, improved the discharging efficient of material, reduce the wearing and tearing between itself and the die cavity simultaneously, in the service life of having improved mould, reduced the processing cost of biological material.

The specific embodiment
Film of the present invention chamber comprises extruded segment 1 and the discharging section 2 along arrival end to the port of export, the dead in line of extruded segment 1 and discharging section 2, and the splayed shape that extruded segment 1 reduces gradually for bore from outside to inside, the bore at each position of discharging section 2 is unanimity.The cross sectional shape of die cavity can be circular, square, rhombus, hexagon.The interior bore of the bore of discharging section 2 and extruded segment 1 is consistent.
When the present invention works, biological material is by the extruded segment 1 of screw rod 3 helical feed to the die cavity, because extruded segment 1 is the splayed shape for what bore from outside to inside reduced gradually, so material easily enters in the die cavity, after the extrusion modling, enter discharging section 2, each position of discharging section 2 is all consistent, the interior bore of the bore of discharging section 2 and extruded segment 1 is consistent, because the bore unanimity, extruding force diminishes relatively, and mass output rate is improved, reduced simultaneously and die cavity between wearing and tearing, when the present invention works, in external peripheral one solenoid tube 4 of mould, outer indirect current source, realization improves the crudy of biological material to the heating of mould.
Mould of the present invention is through Rockwell 54 Quenching Treatment, to improve its hardness and wearability, bore 49.5mm with die cavity discharging section 2 is an example, the degree of depth that inserts into the inner through research screw rod 3 is good with 80mm, when the length of mould is decided to be 355mm, be gradually reduced to 49.5mm with the bore of original discharging section 2 from 53.5mm, the degree of depth 30mm that screw rod 3 inserts into the inner, the length of mould is decided to be 352mm and compares, its product percent of pass is promoted to more than 95% from 80%, production efficiency is promoted to 200kg/h by 120kg/h, and the density of product is by 0.8-1.0t/m
3Be promoted to 1.2-1.4t/m
