Colour mixture drying process of granule material, install ejection of compact pipeline 48 between discharge mechanism 5 and the air cooling mechanism 4, granule material in air-blower 45B will second bellows 401 is carried to in the hopper 50 that gathers materials, granule material in the hopper 50 that gathers materials falls to colour mixture machine 51 under the wind-force effect of air-blower 45B and the gravity action of granule material self, and the high-speed looks mutual friction that rolls produces heat under the effect of stirring plectrum 52, and then make colour mixture machine 51 can also get rid of the moisture on the granule material when carrying out the colour mixture, and finally, the granule material after the colour mixture is dried can be bagged and is collected.
The total process of raw material treatment: 1. the raw materials are plasticized into molten colloid by the heater 200 in the accommodating cylinder 201, and are stirred and extruded by the spiral feeding rod 203, so that the molten colloid is uniformly plasticized, and is conveyed to the screen changing assembly 21;
2. the molten colloid is filtered in the screen changing assembly 21, the filtered molten colloid flows into the granulating chamber 32 and is cut into granules by the main cutter 3120, and the granules are cooled and formed by the first fan 330 and collected into the aggregate conveying pipeline 341;
3. under the transportation of the second fan 340, the blower 45A and the blower 45B, the granules are sequentially cooled and dried by the first wind box 400 and the second wind box 401 from the aggregate transportation pipeline 341, then transported to the aggregate hopper 50, and finally dropped into the color mixer 51 to be mixed with color by stirring.
The raw materials in this embodiment are membrane roll crushing material, and the air-cooled granulator carries out the plastify through plastify extrusion mechanism 2 to the membrane roll powder and extrudes, and rethread granulating mechanism 3 cuts the grain, cools off through air-cooled mechanism 4 after that, carries out colour mixture drying through discharge mechanism 5 at last, has realized making into the granule raw materials that can recycle again with the crushing material of membrane roll waste material, has reached the secondary recycle's of membrane roll waste material mesh. Therefore, the problem of waste treatment of the film roll in the production process is solved, the generation of waste is reduced, the production cost is reduced, and the production requirement of recycling and reutilizing the film roll waste to manufacture plastic particle raw materials can be well met.
Of course, the present invention may have other embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative effort, and all of them are within the protection scope of the present invention.
