The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Following examples will contribute to those skilled in the art further to understand the present invention, but not limit in any form the present invention.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make some distortion and improvement.These all belong to protection scope of the present invention.
embodiment 1
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 described some double screw extruders 2 is connected with pipe chain conveyer 7 respectively, discharging opening and described some storage containers 3 corresponding being connected one by one; The import of described some defeated grain pumps 4 and some storage containers 3 corresponding being connected one by one, outlet is connected with Conveying Chute 5 respectively; Described water tank 1 is connected with described some storage containers 3 respectively; Described dewaterer 6 is arranged on the end of described Conveying Chute 5.
Fig. 2 is the structural representation of facing of Conveying Chute in apparatus of the present invention etc.; As shown in Figure 2, degradable resin composition interlock process units also comprises header tank 8; The delivery port of described header tank 8 is connected by outlet pipeline with water tank 1, and water inlet is connected by inlet pipeline with the delivery port of dewaterer 6; In described header tank, be provided with sewage-treatment plant; Axial and the horizontal direction of described Conveying Chute has angle.
When degradation plastic particle (resin combination) the interlock process units of the present embodiment is worked, the material that blend is good is transported to respectively the feeding zone of each double screw extruder 2 by pipe chain conveyer 7, each double screw extruder 2 carries out melt blending, supercharging extruding pelletization to the material entering wherein, and the particle of generation enters storage container 3 separately; Storage container 3 is connected with water tank 1, wherein stores water, and particle enters the compound of rear formation water and particle; The defeated grain pump 4 of each storage container 3 correspondences pumps to Conveying Chute 5 by the water of wherein storage and the compound of particle respectively, by Conveying Chute 5, is transported to dewaterer 6, obtains product pellet after dehydration.On the other hand, the water outlet of dewaterer 6 enters header tank 8, after processing, generates clean water by the sewage-treatment plant of header tank 8 interior settings, and clean water enters in water tank 1 and supplies to recycle, and has avoided the waste of water data.
In the present embodiment, described Conveying Chute is the square groove of stainless steel, and its angle axial and horizontal direction is 15～30 °.When angle is too small, when the compound of water and particle is carried, particle is easily trapped in Conveying Chute, causes it in water, to soak rotten, thereby affects final product percent of pass; When angle is excessive, flow intensity is excessive, can not make particle arrive stably next procedure, easily causes the damage of the dewaterer of its end simultaneously; 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, described defeated grain pump is stainless steel water pump; In the water of carrying by described defeated grain pump and the compound of particle, the weight ratio of water, particle is 5～10: 3.When the weight ratio of water and particle is too small, particle conveying capacity is very few, causes the low of efficiency; 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 easily damage.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 5～10: 3 for good, more preferably 7: 3.
The interlock that the present embodiment has been realized many double screw extruders by unified feeding device and pay-off is produced, the isoparametric choose reasonable of weight ratio of water, particle in the water of carrying by angle and the defeated grain pump of the axial and horizontal direction to Conveying Chute and the compound of particle; While having avoided traditional degradation plastic particle to produce, 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, realize the continuous production that reliability is truly strong, efficiency is high, well met the demand of the suitability for industrialized production of degradation plastic.
