Description
Technical Field
The invention relates to the technical field of wood-plastic composite material processing devices, in particular to a granulating, exhausting and overflowing removing device for a high-filling wood-plastic composite material.
Background
The wood-plastic composite 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 the plant fiber serving as a main raw material of the wood-plastic composite 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 wood-plastic composite to extrude unstable phenomenon because of the overweight production of moisture in the pelletization process of extruding, especially the natural gas vent, unstable fuse-element can overflow from the gas vent occasionally under the effect of unbalanced interior pressure, appears seriously spouting the material phenomenon even, and more serious can block up the gas vent, can increase the moisture content in the composite finally, leads to the follow-up unstability of strip of appearing, intermittent type nature even expects absolutely.
Disclosure of Invention
The invention discloses an air exhaust and overflow removal device for granulation of a high-filling wood-plastic composite material, aiming at the problems that the flowability of the high-filling wood-plastic composite material is poor and the air exhaust port is blocked by overflowing of the material easily at a natural air exhaust port in extrusion granulation.
In order to achieve the purpose, the application is realized by the following technical scheme:
the utility model provides a high packing wood-plastic composite granulation is exhausted and is removed overflow device, includes the storage compartment, the storage compartment includes storage compartment one and storage compartment two, and two storage compartments link to each other, the storage compartment sets up on the barrel, and its top is equipped with the natural gas vent, is equipped with the exhaust hole on the barrel.
Preferably, the natural gas vent is mounted above the vent hole of the barrel.
Preferably, the width of the natural gas outlet is greater than the width of the storage chamber.
Preferably, the first accumulator chamber and the second accumulator chamber can slide between the machine barrel and the natural exhaust port.
Preferably, the first storage chamber and the second storage chamber are provided with through holes at the upper part and the lower part.
Preferably, a handle is arranged outside the second storage chamber.
The invention adopts a sliding type double-station storage chamber structure to quickly clean the melt material overflowing from the vent hole in the granulation process of the high-filling wood-plastic composite material, has convenient operation and high efficiency, and effectively ensures the stable extrusion of the high-filling wood-plastic composite material.
Drawings
FIG. 1 is a schematic structural view of a pelletizing, exhausting and overflowing removing device for a high-filling wood-plastic composite material.
1. A barrel; 2. a natural exhaust port; 3. a first material storage chamber; 4. a second material storage chamber; 5. an exhaust hole; 6. and (4) a handle.
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 is poor to high packing wood-plastic composite material mobility, extrudes the easy problem that the material spills over the shutoff gas vent that appears of natural gas vent in the granulation, discloses a high packing wood-plastic composite material granulation exhaust removes overflow device.
As shown in fig. 1, the granulation air exhausting and overflowing preventing device of the present embodiment includes a cylinder 1, a natural air outlet 2, a first material storage chamber 3, a second material storage chamber 4, an air exhausting hole 5, and a handle 6.
Storage compartment one 3 links to each other with storage compartment two 4, and storage compartment one, two 3, 4 set up on barrel 1, and storage compartment one, two 3, 4 tops are equipped with the great natural gas vent 2 of width, are equipped with exhaust hole 5 on barrel 1, and natural gas vent 2 also satisfies simultaneously and installs in the exhaust hole 5 top of barrel 1.
The lower parts of the first storage chamber 3 and the second storage chamber 4 are provided with sliding blocks which can slide in the sliding grooves on the machine barrel 1, namely the storage chambers 3 and the second storage chambers 4 can slide between the machine barrel 1 and the natural exhaust port 2.
The first storage chamber 3 and the second storage chamber 4 are through holes from top to bottom, and a handle 6 is arranged outside the second storage chamber 4.
Example 2
The embodiment discloses the operating principle of a device for pelletizing, exhausting and removing overflow of a highly filled wood-plastic composite material:
when the high-filling wood-plastic composite material is melted and then passes through the vent holes 5, the pressure in the melt is released, water vapor and volatile components are rapidly discharged through the vent holes 5, and meanwhile, due to the fact that the moisture content is too high, the pressure difference between the inside and the outside of the melt is too large, and the material can enter the storage chamber I3 along with the discharge of the water vapor and the volatile components.
When the material in the first storage chamber 3 is to be filled, the first storage chamber 3 and the second storage chamber 4 slide through the handle 6, so that the empty second storage chamber 4 enters the space between the exhaust hole 5 of the cylinder 1 and the natural exhaust port 2, and the collection of overflowed materials is continuously completed.
Meanwhile, overflowing materials in the first material storage chamber 3 are discharged under the self weight.
The embodiment adopts slidingtype duplex position storage compartment structure to carry out timely quick clearance to the melt material that highly fills wood-plastic composite granulation in-process and spill over from exhaust hole 5, and convenient operation, and efficient, has effectively guaranteed that highly fills wood-plastic composite's stability is extruded.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
