Description
Technical field
The present invention relates to a kind of reactive system of chemical fibre industry polymkeric substance, relate in particular to the sticking system of the modified accent of a kind of plastic waste.
Background technology
The sticking technology of modified accent that is used for the plastic waste raw material of terylene short fiber production at present mainly is: the liquid plastic waste raw material after the fusion is sent into its special-purpose vacuum separation tower; Multi-layer porous plate is arranged in the vacuum separation tower; Liquid raw material successively increases surface-area through porous plate; Low molecular impurity gasification is separated, improve the purity and the viscosity of raw material, promote the quality of finished product product greatly.
Through above method, can be with the viscosity system of raw material 0.5 0.68 when being increased to discharging when beginning to import.Can satisfy processing requirement fully though the PET plastic raw materials that this technology is produced is made common silk, when making HS silk or industry silk, need viscous modulus to reach more than 0.7.Test through tackify:, can increase the vacuum tightness in the vacuum separation tower in order to improve the viscous modulus of PET raw material.After material viscosity increases, the rapid variation of fluidity of molten, flow velocity is slow, increases discharging time greatly, has a strong impact on production efficiency.If viscous modulus is increased to more than 0.75, will cause melt feed to flow downward, make parturient paresis.
Therefore, how to improve the production HV especially the production efficiency of the PET plastic raw materials of viscous modulus more than 0.7 become a technical barrier.
Summary of the invention
The invention provides the sticking system of the modified accent of a kind of plastic waste, can high efficiency production HV the PET plastic raw materials of viscous modulus more than 0.7 especially.In order to realize the foregoing invention purpose, the present invention has adopted following technique means:
The modified accent of a kind of plastic waste glues system, comprises the vacuum separation tower; Said vacuum separation tower top is provided with feed(raw material)inlet and vacuum port; Said vacuum separation tower below is provided with discharge port; Said vacuum separation tower appearance is provided with the heating agent coil pipe; Be arranged at intervals with porous plate on the said vacuum separation tower internal vertical direction; Said discharge port also connects the sticking device of a modified accent of secondary.
The sticking device of the modified accent of said secondary comprises casing and the vacuum pump that is interconnected; Said casing appearance is provided with heating coil, and set inside has the screw rod of screw-blade, and said screw rod is by electric motor driving; Position near the screw rod two ends on the said casing is provided with opening for feed and delivery port respectively, and said opening for feed is communicated with the discharge port sealing, and said delivery port is connected with transferpump;
The heating coil of casing appearance coils along screw axial.
Beneficial effect of the present invention is: owing to added the sticking device of a modified accent of secondary, be provided with screw rod in this device, not only can promote raw material, and can stir raw material and improve viscosity; Singly add a vacuum pump, further gas clean-up is for material viscosity provides reaction environment.More than these factor combine to have facilitated the obvious raising of High Viscosity PET plastic raw materials production efficiency.
Description of drawings
Fig. 1 is the structural representation of the sticking system of the modified accent of plastic waste of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred implementation of the sticking system of the modified accent of plastic waste of the present invention is made detailed description:
As shown in Figure 1, the sticking system of the modified accent of this plastic waste comprises the sticking device of vacuum separation tower 1 and the modified accent of secondary.Vacuum separation tower 1 is identical with prior art, and tower body is a round shape, and the top is provided with feed(raw material)inlet 3 and vacuum port 2, and the below is provided with discharge port 6; Coiling is provided with heating agent coil pipe 4 on the outside surface, and coil direction is axially identical with vacuum separation tower 1; Be arranged at intervals with a plurality of porous plates 5 on the tower body internal vertical direction.
The sticking device main body of the modified accent of secondary is a horizontally disposed cylindrical box 11, and it is connected with vacuum pump 14; The two ends of casing 11 are offered opening for feed 12 and delivery port 9 respectively, and the discharge port of opening for feed 12 and vacuum separation tower 16 is connected delivery port 9 external transferpumps 8 through flange; Casing 11 outside surfaces coil vertically heating coil 7 are set; Be parallel in the casing 11 screw rod 10 that has screw-blade axially is set; It is near the inwall bottom surface of casing 11; Opening for feed 11 is positioned at the top of screw rod 9; Delivery port 9 is positioned at the below of screw rod 10, and screw rod 10 is driven by motor 14, and the screw rod 10 of band screw-blade is formed a stirring puopulsion unit with motor 13.
Liquid PET raw material gets into vacuum separation tower 1 inside of high temperature (4 heating of heating agent coil pipe) high vacuum through feed(raw material)inlet 3; Liquid raw material increases surface-area through vacuum separation tower 1 inner multi-layer porous plate 5; Low molecular impurity gasification back is detached by vacuum port 2; Improve material purity, the while, through some porous plate 5 preliminary purification tackifies, 0.5 when making viscous modulus by pan feeding was increased to 0.68 under action of gravity; Reach the sticking purpose of elementary modified accent, flow out the sticking device of the modified accent of entering secondary by discharge port 6 then.
In the liquid raw material sticking through elementary modified accent flows into casing 11, and the vacuum pump 14 of casing 11 through the outside makes its internal vacuum than vacuum separation tower 1 higher one-level, thereby the low molecular impurity in the liquid raw material of inflow is further gasified; Fully detach; Make the purity of raw material higher, simultaneously under high vacuum state, the stirring of the screw-blade through screw rod 10; The raw molecule structure realizes arranging again; Increase material viscosity (coefficient is promoted to more than 0.70, reaches the processing requirement of production HS silk), the sticking work of the modified accent of secondary is accomplished.At last, again by the pushing effect of the screw-blade of screw rod 10, mobile variation and viscosity enhanced liquid raw material is delivered to transferpump 8, transferpump 8 output raw material production spinning.
