plastic melt filtration system-double pillar screen changer
performance of double pillar screen changer
1,Double-piston screen changer works simultaneously. One net works. Another replaced; without interrupting the flow of material and production. And eventually fulfills the exchange of screen without stopping the machine.
2,Exhaust system device can fully defuse the gas mixed in the materials, then improving product quality. And double channels expand the filtration area to meet more productive, more high-quality production need s from customers.
How to work
The double piston Screen Changer allows for filtration of most all polymers without interrupting production during a screen change. The Screen Changer consists of two pistons with each containing a filter cavity. When a screen change is required, one of the pistons is moved out of the housing while the other remains in the operating position. The dirty screen pack is removed and replaced with a new one. The piston is then moved back into the housing to its venting stages before resuming operation. These steps are then repeated for the other piston. This concept allows for continuous filtration with no interruption or loss of production
