Dual-plate dual-station screen changer: A key equipment for enhancing the production efficiency of c

The dual-plate screen changer for cable skin granulation plays a pivotal role in the plastic extrusion and granulation processes. Its structure and characteristics can be summarized as follows:

I. Structure of Dual-Plate Dual-Station Screen Changer

The dual-plate dual-station screen changer primarily consists of two filter plates, the main body of the screen changer, a hydraulic system, and a control system. The two filter plates are installed inside the main body of the screen changer and are used to filter the plastic melt. The hydraulic system is responsible for driving the movement of the filter plates to achieve screen changing operations. The control system is used to control the entire screen changing process, ensuring the accuracy and timeliness of the screen change.

II. Characteristics of Dual-Plate Dual-Station Screen Changer

Uninterrupted Screen Changing: The dual-plate dual-station screen changer features two filter plates. When the screen on one filter plate needs to be replaced, the hydraulic system can drive that filter plate out of the main body of the screen changer, while the screen on the other filter plate continues to work, ensuring production continuity. This design avoids a decrease in production efficiency due to downtime for screen changing.

Stable Material Flow: During normal operation, the plastic melt enters the screen changer from the extruder and is diverted into two parallel flow channels, passing through the screens on the two filter plates for filtration. This design helps ensure that the material flow remains unobstructed during screen changing, reducing changes in material flow temperature and pressure, and thereby minimizing the impact on the production process.

Excellent Sealing Performance: The dual-plate dual-station screen changer typically adopts a flexible pressure-activated sealing structure. This structure can automatically activate and compensate with the melt pressure, ensuring superior sealing performance, effectively preventing material leakage, and reducing material waste.

Fast Screen Changing Speed: Equipped with an energy-storage hydraulic station, the dual-plate screen changer can achieve rapid screen changing. The transition time from the first working position to the second is extremely short, ensuring production continuity and efficiency.

Wide Range of Applications: The dual-plate dual-station screen changer is not only suitable for cable skin granulation processes but is also widely used in granulation, film blowing, pipe, board, sheet, and other types of production equipment.

Wear and Pressure Resistance: The dual-plate dual-station screen changer is characterized by high wear and pressure resistance, which can extend the service life of the equipment and adapt to various high-pressure production environments.

Flexible Heating Methods: The heating method of the dual-plate dual-station screen changer can be selected based on actual production needs, with options such as electric heating or heat medium heating to meet different heating requirements.

High Temperature Resistance: The dual-plate dual-station screen changer can operate stably at temperatures up to a certain level (e.g., 300°C), suitable for plastic granulation processes requiring high-temperature treatment.

In summary, the dual-plate screen changer for cable skin granulation is characterized by its compact structure, fast screen changing speed, stable material flow, excellent sealing performance, wide range of applications, wear and pressure resistance, flexible heating methods, and high temperature resistance. These characteristics make the dual-plate screen changer play an important role in the cable skin granulation process.
