Two channel hydraulic screen changer for plastic extruder
Description of two channel hydraulic screen changer for plastic extruder
This kind of two channel hydraulic screen changer now becomes more and more popular in nowadays, since all the manufacturer of plastic products take more care of the capacity of production and quality of the products. Due to the structure and features of this kind of screen changer, we do not need to stop the working machine when replce the dirty mesh , and also non-interrupt the production. so it can realize the continuous uninterrupted production.
Features of two channel hydraulic screen changer for plastic extruder
1), Two slide bars instead of the conventional flat plate
2), The slide bar is pushed and pulled by hydraulically, which is different from the hydraulic unit of the single plate hydraulic screen changer, does not have the accumulator.
3), 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.
4), 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 screen change process
1), the breaker plates with screen on the working position.
2), one slide bar is pushed out .When screen change is required, the two slide bars will be pushed out by hydraulically one after another.
3), the dirty screen on the breaker plate is replaced to a fresh screen by manual operation,.
4), Air bleeding process,it is finished in a short time.
