Abstract
The utility model discloses a novel nitrogen high-pressure injection nozzle, which comprises an adjusting screw, a back seat, a top plate, a spring, a valve body, and a valve rod, wherein the adjusting screw is mounted on the back seat; the valve rod is mounted in the valve body; and the spring is mounted between the top plate and the valve rod. The nitrogen high-pressure injection nozzle is one of assemblies necessary for a nitrogen-filled twin-screw expansion dry extruder explosion drying technology and other twin-screw extruder devolatilization technology requiring high devolatilization efficiency; moreover, the nozzle is an effective means and guarantee for safe nitrogen injection and process adjustment; and the safety and the reliability enable the application of the novel explosion drying technology and efficient devolatilization technology. The nitrogen high-pressure injection nozzle is different from a gas-auxiliary gas needle used for mold industry and a nitrogen-filled injection nozzle used for an injection molding machine; in addition, the nozzle is a high-pressure resistant pneumatic valve body which injects nitrogen in an extruder melt to improve drying effect and other devolatilization efficiency and is adjustable according to pressure variation of the melt.
Description
Technical field
The utility model relates to the injection device on a kind of screw extruder, relates in particular to a kind of novel nitrogen high-pressure injection nozzle.
Background technology
In the dry process of polymer, polymer is sent into expansion-exsiccation machine behind extrusion dehydration, shear to improve the temperature of polymer by control, when polymer just can carry out effective expansion drying when die head is extruded, in inflated with nitrogen twin-screw expansion drying extruder, nitrogen or other inert gas are expelled to withstand voltage zone in the extruder, so just provide a bigger blasting medium of effectiveness to make dry run easier to be more effective, make the final water content of sizing material lower, can also reduce simultaneously the basal temperature of polymer, thereby help guaranteeing the performance and the quality of polymer itself, the also nobody's grasp at present except my company at home of this technology, charge into nitrogen and can further improve devolatilization efficient effectively in using the process of double screw extruder to the polymer solution devolatilization, this technology is also nobody's grasp at present at home.
The utility model content
The purpose of this utility model provides a kind of in inflated with nitrogen twin-screw expansion drying extruder, nitrogen or other inert gas are expelled to withstand voltage zone in the extruder, can make dry run easier to be more effective, make the final water content of sizing material lower, the basal temperature of polymer be can also reduce simultaneously, the performance of polymer itself and the novel nitrogen high-pressure injection nozzle of quality guaranteed.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of novel nitrogen high-pressure injection nozzle, comprise adjustment screw, back seat, top board, spring, valve body and valve rod, adjustment screw is installed on the back seat, and valve rod is installed in the valve body, and spring is installed between top board and the valve rod.
Described back seat and valve body are formed the shell of nozzle by being threaded.
Between described valve body and the valve rod seal is installed.
Described valve body has endoporus cone structure and male cone (strobilus masculinus) structure.
Described valve stem end is a cone structure.
Be connected with scale by screw on the described back seat.
Described adjustment screw is fixed on the back seat by nut.
A kind of novel nitrogen high-pressure injection nozzle of the utility model is that inflated with nitrogen twin-screw expansion drying extruder explosion dry technology and other have one of necessary assembly in the double screw extruder devolatilization technology that high devolatilization efficient requires, it is the nitrogen safety injection, the effective means of process adjustments and guarantee, it safe and reliable makes this new explosion dry technology and the high efficiency devolatilization The Application of Technology possibility that becomes, nitrogen high-pressure injection nozzle is different from the auxiliary air tube of gas that die industry uses, also be different from the inflated with nitrogen injection-moulding nozzle that uses on the injection machine, and a kind of especially nitrogen is expelled to extrusion machine fused mass inside improving drying effect and other devolatilization efficient, and can follows according to melt pressure and change the high voltage bearing pneumatic valve body of regulating.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of novel nitrogen high-pressure injection sealed nozzle status architecture cutaway view of the utility model;
Fig. 2 is a kind of novel nitrogen high-pressure injection nozzle open mode structure cutaway view of the utility model;
Fig. 3 is an A place partial enlarged drawing among the utility model Fig. 2;
Among the figure: 1, adjustment screw; 2, scale; 3, nut; 4, back seat; 5, top board; 6, spring; 7, valve body; 8, valve rod; 9, seal.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, novel nitrogen high-pressure injection nozzle, comprise adjustment screw 1, scale 2, nut 3, back seat 4, top board 5, spring 6, valve body 7, valve rod 8 and seal 9, adjustment screw 1 is installed on the back seat 4, fixing by nut 3, scale 2 is connected on the back seat 4 by screw, valve rod 8 is installed in the valve body 7, can slide up and down, spring 6 is installed between top board 5 and the valve rod 8, back seat 4 and valve body 7 have been formed the shell of nozzle by being threaded, seal 9 is installed between valve body 7 and the valve rod 8, and valve body 7 has endoporus cone structure and male cone (strobilus masculinus) structure, valve rod 8 ends are cone structure, the adjustment screw 1 that top board 5 is installed on the back seat 4 holds out against, and can change the height of spring 6 by adjustment screw 1, thus the pretightning force of 6 pairs of valve rods 8 of given spring, the pretightning force that adjustment screw 1 imposes on the spring 6 is close to the terminal conical surface of valve rod 8 and the endoporus conical surface of valve body 7, thereby the realization valve seal, valve body 7 is threaded with extruder barrel, and uses conical surface seal.
As shown in Figure 1, be in sealing state during the nozzle normality, connect source of the gas, gases at high pressure act on valve rod 8, and when its active force during greater than a certain setting value (the initial coupling mechanism force of valve body), valve body 7 is opened; Valve body 7 initial coupling mechanism forces apply and regulate by adjustment screw 1, and the regulated quantity by scale 2 these adjustment screw 1 of record can make nozzle have an initial coupling mechanism force scope of bigger valve body by adjustment screw 1, to be suitable for more operating mode.
As shown in Figure 2, connect source of the gas, the gases at high pressure active force is in valve body 8, and when its active force during greater than the active force of 6 pairs of valve rods 8 of spring, valve rod 8 upwards slides, and promptly valve body 7 is opened; After closing source of the gas, the pretightning force that adjustment screw 1 imposes on the spring 6 is pushed back valve rod 8 rapidly, and is close to the endoporus conical surface of valve body 7, thereby realizes that valve body 7 seals once more.
Shown in Fig. 3, be the endoporus cone structure and the valve rod 8 terminal cone structures of valve body 7,, realize valve seal when adjustment screw 1 imposes on pretightning force on the spring 6 when the endoporus conical surface of the terminal conical surface of valve rod 8 and valve body 7 is close to.
The medium that the utility model uses can be a nitrogen, also can be other inert gas.
