The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.Following examples will help those skilled in the art further to understand the present invention, but not limit the present invention in any form.Should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement.These all belong to protection scope of the present invention.
As shown in Figure 1, degradation plastic particle (resin combination) interlock process units comprises pipe chain conveyer 7, some double screw extruders 2, some storage containers 3, some defeated grain pumps 4, water tank 1, Conveying Chute 5 and dewaterer 6; The charging aperture of said some double screw extruders 2 links to each other with pipe chain conveyer 7 respectively, and discharging opening links to each other with said some storage containers 3 are corresponding one by one; The import of said some defeated grain pumps 4 links to each other with some storage containers 3 are corresponding one by one, and outlet links to each other with Conveying Chute 5 respectively; Said water tank 1 links to each other with said some storage containers 3 respectively; Said dewaterer 6 is arranged on the end of said Conveying Chute 5.
Fig. 2 is the structural representation of facing of the Conveying Chute in apparatus of the present invention etc.; Can know that by Fig. 2 degradable resin composition interlock process units also comprises header tank 8; The delivery port of said header tank 8 and water tank 1 link to each other through outlet pipeline, and water inlet links to each other through inlet pipeline with the delivery port of dewaterer 6; Be provided with sewage-treatment plant in the said header tank; Axial and the horizontal direction of said Conveying Chute has angle.
When degradation plastic particle (resin combination) the interlock process units of present embodiment is worked; The material that blend is good is transported to the feeding zone of each double screw extruder 2 respectively through pipe chain conveyer 7; 2 pairs of entering of each double screw extruder material wherein carries out melt blending, supercharging extruding pelletization, and the particle of generation gets into storage container 3 separately; Storage container 3 links to each other with water tank 1, wherein stores water, and particle gets into the compound that the back forms water and particle; The water that each storage container 3 corresponding defeated grain pump 4 will wherein be stored respectively and the compound of particle pump to Conveying Chute 5, are transported to dewaterer 6 through Conveying Chute 5, promptly get product pellet after the dehydration.On the other hand, the water outlet of dewaterer 6 gets into header tank 8, handles the back through the sewage-treatment plant that is provided with in the header tank 8 and generates clean water, and clean water gets in the water tank 1 and supplies to recycle, and has avoided the waste of water data.
In the present embodiment, said Conveying Chute is the square groove of stainless steel, and its angle axial and horizontal direction is 15～30 °.When angle was too small, particle was trapped in the Conveying Chute easily when the compound of water and particle was carried, and it is rotten to cause it in water, to soak, thereby influences final product percent of pass; When angle was excessive, flow intensity was excessive, can not make particle arrive next procedure stably, caused the damage of its terminal dewaterer simultaneously easily; Through actual multi-pass operation adjustment, it is good that the angle axial and horizontal direction of selection Conveying Chute is 15～30 °, more preferably 20 °.
In the present embodiment, said defeated grain pump is the stainless steel water pump; The weight ratio of water, particle is 5～10: 3 in the water of carrying through said defeated grain pump and the compound of particle.When the weight ratio of water and particle was too small, the particle conveying capacity was very few, caused the low of efficient; When the weight ratio of water and particle is excessive, need supporting defeated grain pump power to require to improve, cause the increase of cost, on the other hand, also make defeated grain pump damage easily.Through actual multi-pass operation adjustment, the weight ratio of selecting water, particle in the compound of water that defeated grain pump carries and particle is to be good at 5～10: 3, more preferably 7: 3.
Present embodiment has been realized the interlock production of many double screw extruders through unified feeding device and pay-off, through to Conveying Chute axially with the compound of the water of the angle of horizontal direction and the conveying of defeated grain pump and particle in the isoparametric choose reasonable of weight ratio of water, particle; Many double screw extruders manpower that the inefficiency that causes and every extruder need at least one operating personnel to cause that works alone is produced high deficiency when having avoided traditional degradation plastic particle to produce; Realize good reliability truly, the continuous production that efficient is high, well satisfied the demand of the suitability for industrialized production of degradation plastic.
