Polymer melt filter-new continuous screen changer
the new continuous screen changer is based on the single plate screen changer, and it add the auto exhaust system , and the two filter screen cavities distance is very close, when the screen replace is required, the plate with dirty screen is moved out and the new screen is moved to the working position. and the exhaust system started at the same time. so our screen changer can not only filter impurities, but also can greatly improve the plasticizing and homogenization effect of the raw material, make the product structure more homogeneous and product surface smoothness and higher quality .
The new continuous screen changer consists of main body, slide plate, heater, hydraulic unit, temperature control system and pressure monitoring system. Different from the above Single-plate type screen changer, it changes the screen without interrupting extrusion production.
Features of the new continuous screen changer
1,No need to stop the working machine when changing the screen, no material explosion, noiseless, no material leakage, or production interrupt while working.
2,This screen changer (self-owned patent ) is characterized by the convenience and safety to change the filtering screen with it. It is time-saving to install the filtering screen with the screen changer, and there is no need to manually disassemble the machine, adjust the para-position screen, or install the lock pact between different screens, thus the screen changing operation will be reduced by 90%.
3,The new continuous screen changer is especially applicable to foaming plate products such as XPS, EPS, EPE and cast film. It ensures the screen changing without machine halt or production interrupt, which has been widely tested and verified in production practice.
