Double Plate Hydraulic Continuous Screen Changer
The double plate hydraulic continuous screen changer is a pivotal piece of equipment in various industrial processes, particularly in the plastics, rubber, and chemical fiber industries. This innovative device facilitates continuous production by enabling the swift replacement of filters without halting the production line, thereby significantly enhancing efficiency and reducing downtime.
Working Principle
The core of the double plate hydraulic continuous screen changer lies in its design featuring two parallel slides, each equipped with a circular filtering station. Here's how it works:
Hydraulic Power: The operation is powered by a hydraulic station, which is controlled by an operator using a handle button.
Filter Displacement: By pressing the corresponding button on the handle, the hydraulic system drives one of the slides to displace, allowing the filter station on it to be moved out of the main body of the screen changer. Meanwhile, the filter station on the other slide continues to operate, ensuring production continuity.
Filter Cleaning and Replacement: Once the slide is moved out, the operator can shut down the hydraulic station, clean the filter, and replace it with a new one.
Slide Reinsertion: After the new filter is installed, the hydraulic station is restarted, and the slide is pulled back into the main body by pressing the corresponding pull button on the handle, initiating a new filtering cycle.
Alternating Operation: The process is repeated for the other slide, ensuring that both filtering stations are regularly cleaned and replaced, maintaining optimal production conditions.
