Continuous screen changer-single plate screen changer
Single plate screen changer
consists of main body, slide plate, heater and hydraulic unit with accumulator, and electric controlling box. It is driven by hydraulic power, and the slide plate carries 2 pieces breaker plates can move linearly in both directions to achieve screen changing in a short time.
Features of theDHB series single plate hydraulic screen changer
1) quick
To move from the filtering screen in use to the clean screen takes only a minimum time, less than 2 seconds
•Extraction and replacement of the filtering screens take place very quickly and maintenance can be carried out in a short time
•The speed of the change from one screen to the other means that the action of the
extruder is not interrupted
2)flexible
Single plate screen changer can be mounted both horizontally and vertically without affecting performance; in addition the single plate screen changer can be controlled by just one hydraulic unit.
•Mounted both horizontally and vertically, the single plate screen changer can be introduced very successfully onto pre-existing installations or where the space available is restricted, but without compromising high quality processing
•Several single plate screen changers can be controlled by the same hydraulic unit, resulting in large savings and maximum use of space
3)safe
The screen changer is provided with several devices which guarantee its safe use.
•The safety blocking system of the doors and the hydraulic unit protects from the movements of the plates and from accidental opening during maintenance
•The block of the accumulator prevents the hydraulic unit to exceed the adjusted maximum pressure
• guarantee a perfect seal during the sliding of the plates
Special installations
The DHB SERIES can be installed both horizontally and vertically and can be introduced into pre-existing installations or where the space available is restricted but without compromising high quality processing.
For maximum use of space, and economic advantage, several DHB series screen changers can be connected to one hydraulic unit.
