Double  plate double working position hydraulic screen changer

This kind of screen changer is better than the single plate screen changer, there are two flow channels, so when we replace the dirty screen, the melt folw will not be interrupted.

It contains two screens that work at the same time: one screen works, while the other one is changed during the process of screen replacements, thus the replacement without machine halt is ensured and no interrupt of material fluid and of production will occur. Therefore, the screen changer meets the customers' requirement of higher productivity and better quality.

1,Automatic screen changing by hydraulic; Machine non-stopped\

2,Special sealed structure design(self-owned patent),excellent effect, no material leakage for more than five years.

3, Simple construction, reliable operation; Easy maintenance, lower running cost;

4, Flow channel without the dead spots, it's easy to clean and maintain the machine.

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

Application fields:

1. Used for the production of plate, sheet, cast film, pipe, granulation and so on.

2. Applicable to the production line of colossal, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture, filtering screen replacement available without machine halt.

Commissioning
