Description

Forced exhaust device for high-filling biomass material extrusion
Technical Field
The invention relates to the technical field of biomass material processing devices, in particular to a forced exhaust device for extruding high-filling biomass materials.
Background
The biomass material is a novel composite material which has the double performances of plastic processing performance and wood texture and is prepared by fully utilizing agricultural and forestry wastes and plastic reclaimed materials. The content of plant fiber which is the main raw material of the biomass material is usually over 50 percent, and the addition of the high-content plant fiber changes the rheological behavior of a resin matrix, increases the viscosity, deteriorates the fluidity and is difficult to process. On the other hand, the water content of the plant fiber is usually as high as 10%, the drying cost of the plant fiber through heating equipment is too high, the plant fiber is usually directly used, on the other hand, the biomass fiber also contains a large amount of organic volatile components, and the content of different biomass fibers is different. This just leads to biomass material to produce extrusion unstability phenomenon because of the overweight of moisture in the extrusion pelletization process, especially the natural gas vent, unstable fuse-element can overflow from the gas vent occasionally under the effect of unbalanced interior pressure, the serious material spraying phenomenon appears even, more serious can block up the gas vent, can increase the moisture content in the combined material finally, leads to the unstability of follow-up strip of appearing, intermittent type nature even material absolutely.
Disclosure of Invention
The invention provides a forced exhaust device for extruding high-filling biomass materials, aiming at the problems that the high-filling biomass materials are poor in flowability and the natural exhaust port is easy to cause material overflow and block the exhaust port in the extrusion granulation process.
In order to achieve the purpose, the application is realized by the following technical scheme:
the forced exhaust device for the high-filling biomass material extrusion comprises an exhaust funnel, wherein one end of the exhaust funnel is arranged on a machine barrel, and the other end of the exhaust funnel is connected to an inlet of a crushing fan through a material pipe.
Furthermore, the crushing fan is provided with an air outlet pipe.
Further, the machine barrel is provided with an exhaust hole.

Detailed Description
The invention is further illustrated by the following specific examples. The starting materials and methods employed in the examples of the present invention are those conventionally available in the market and conventionally used in the art, unless otherwise specified.
Example 1
The embodiment provides a forced exhaust device for extruding high-filling biomass material, aiming at the problems that the high-filling biomass material is poor in flowability, and the natural exhaust port is easy to cause material overflow and block the exhaust port in extrusion granulation.
As shown in fig. 1, the forced air discharging device for extrusion in this embodiment includes a cylinder 1, an air discharging hole 2, an air discharging cylinder 3, a material passing pipe 4, a crushing fan 5, and an air outlet pipe 6. The crushing fan 5 is composed of a crusher and a fan.
One end of the exhaust funnel 3 is arranged on the machine barrel 1, the other end of the exhaust funnel is connected to an inlet of a crushing fan 5 through a material 4 pipe, and the crushing fan 5 is provided with an air outlet pipe 6.
The machine barrel 1 is provided with an exhaust hole 2, and the exhaust cylinder 3 is arranged on the exhaust hole 2 of the machine barrel 1 and sealed with the machine barrel 1.
Example 2
The embodiment discloses the working principle of a forced exhaust device for extruding high-filling biomass materials:
when the high-filling biomass material is melted and passes through the vent holes 2, the pressure in the melt is released, water vapor and volatile components are rapidly discharged through the vent holes 2, and meanwhile, because the moisture content is too high, the pressure difference between the inside and the outside of the melt is too large, the material can enter the exhaust funnel 3 along with the discharge of the water vapor and the volatile components.
After the crushing fan 5 is started, the crushing fan 5 discharges air from the exhaust funnel 3 to the outside through the air outlet pipe 6, so that negative pressure is generated in the exhaust funnel 3, and sporadic material particles, water vapor and volatile components entering the exhaust funnel 3 are sucked into an inlet of the crushing fan 5 through the material passing pipe 4.
The gas is directly discharged after passing through the crushing fan 5, and the material particles are crushed and discharged through the discharge hole after passing through the crushing fan 5, so that the whole exhaust channel is prevented from being blocked.
This embodiment adopts broken fan 5 to clear up fast the fuse-element material that overflows from exhaust hole 2 among the high packing biomass material granulation process, and the negative pressure that broken fan 5 produced simultaneously more is favorable to the discharge of vapor and volatile components, and whole device convenient operation is efficient, has effectively guaranteed the stable of high packing biomass material and has extruded.
The foregoing is illustrative of the preferred embodiments of the present invention and is not to be construed as limiting thereof in any way. Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. It will be apparent to those skilled in the art from this disclosure that many changes and modifications can be made, or equivalents modified, to the invention without departing from the scope of the invention. Therefore, any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present invention are included in the protection scope of the present invention.
