Wherein, described vacuum meter is connected with vacuum bed, and described vacuum bed is installed on the machine barrel of extruder, and described vacuum bed links to each other with the vacuum cylinder inlet end by pipeline, the vacuum cylinder outlet side is connected with the inlet end of vavuum pump, and the outlet side of vavuum pump is connected with steam-water separator.
Described vacuum bed is connected with the vacuum cylinder inlet end by stainless steel tube or enhancing rubber tube, pipe joint and T type tee ball valve.
Described vacuum cylinder outlet side is connected with the inlet end of vavuum pump by T type tee ball valve and enhancing rubber tube.
Described enhancing rubber tube be provided with filter at vavuum pump air inlet place.
Described vavuum pump is through the solenoid control moisturizing.
Described steam-water separator is connected with drainpipe.
Described vacuum cylinder and vavuum pump are installed on the installing plate of awl double screw extruder.
Compared with prior art, the utlity model has following advantage:
(1) high efficiency: the O RunddichtringO is housed, good airproof performance on the vacuum bed in the two extruder vacuum pumping systems of this awl; Vacuum bed and vacuum cylinder are connected to stainless steel tube, the angle optimal design, transition on the corner thaws, and has greatly reduced resistance coefficient, and energy loss reduces, the sealing of whole system is guaranteed, after starting working, can reach the desired vacuum of extruder rapidly, and intuitively be shown by the vacuum meter that is installed on the vacuum bed, at vacuum bed two observation windows be arranged, close vavuum pump, mention the situation that the vacuum bed lid just can be observed raw material in the machine barrel intuitively.
(2) system stability, reliable: the vacuum cylinder profile in the two extruder vacuum pumping systems of this awl is particular design, whole pipeline and vacuum bed installation site optimal design, exterior line adopts rigidity to be connected with flexible combination, guarantee pipe-line system compact conformation, attractive in appearance, increase the pipeline seismic stability simultaneously.Under correct operation, the required cleaning room interval of vacuum cylinder is 2 times of conventional vacuum gas extraction system, saves labour turnover.The base plate of vacuum system adopts special structural design, is conducive to reduce resonance, fatigue, and the effect that causes of forced vibration, and the Shockproof rubber pad is housed on the installing plate, makes native system that good shockproof function be arranged, thus the stability of assurance system.
(3) but Hand scarf: in the circuit design of the two extruder vacuum pumping systems of this awl two T type tee ball valves are arranged, operating position by switch T type tee ball valve when needs cleaning vacuum cylinder makes steam directly enter vavuum pump, the vavuum pump inlet end is equipped with filter, thus but the effect of arrival Hand scarf vacuum cylinder.
(4) dismounting is easy to maintenance: the stainless steel tube that the vacuum bed in the two extruder vacuum pumping systems of this awl is connected with vacuum cylinder adopts buckle-type to connect easy accessibility; The observation window of vacuum cylinder adopts and is threaded, and gets final product at the cleaning vacuum cylinder form of only need outwarding winding, and is fast and convenient; The installation version that vacuum cylinder and vavuum pump are installed has adopted slideable structure, only need unclamp the tightening device during maintenance dismounting, just can skid off vacuum system.Consumption manpower when therefore having saved loading and unloading shortens man-hour, has improved the mechanical work rate.
