Analysis of the Structure and Function of a Dual-Plate Non-Stop Screen Changer for Masterbatch Granu

The dual-plate non-stop screen changer for masterbatch granulation is an efficient and stable component of plastic production equipment, with the following specific structures and features:

I. Structure of the Dual-Plate Screen Changer for Masterbatch Granulation

The dual-plate non-stop screen changer for masterbatch granulation mainly consists of the following parts:

Two parallel sliding plates: Each plate has a filtration station, ensuring simultaneous dual-station operation to enhance production efficiency.

Screen changer body: Used to support and accommodate the two sliding plates and filters, ensuring stable flow of plastic melt during screen changing.

Hydraulic system: Responsible for driving the movement of the sliding plates to achieve screen changing. Power is supplied by a hydraulic station to drive the plates in and out of the screen changer body.

Control system: Typically includes pressure sensors and alarm systems to monitor filter status and trigger alarms when necessary.

II. Features of the Dual-Plate Screen Changer for Masterbatch Granulation

Dual-Channel Dual-Station Design: The design of two parallel sliding plates enables the screen changer to have dual-channel dual-station capabilities, allowing simultaneous operation and increased production efficiency.

Alternating Screen Changing: When the filter on one plate needs replacement, the other plate continues to operate, ensuring production continuity. This design avoids production interruptions due to screen changing.

Minimal Pressure Fluctuation: With dual-station simultaneous operation, where one filter works while the other is being changed, the screen changing process does not cause significant fluctuations in extruder production, ensuring the stability of product quality.

Simple Structure and Easy Operation: The dual-plate screen changer has a relatively simple structural design, making it easy to operate and maintain. The screen changing process can be completed with simple operations such as handle buttons on the hydraulic station.

Automatic Alarm: When the filter becomes clogged or impurities accumulate to a certain extent, the pressure sensor triggers the alarm system, reminding operators to change the screen in a timely manner to ensure smooth production.

Wide Application Range: The dual-plate non-stop screen changer is suitable for filtering almost all polymer melts and can be used with different standards of single-screw or twin-screw extruders. It is widely used in the production of chemical fibers, blown films, flat films, cast films, pipes, sheets, wires, fibers, pelletizing lines, recycling, and many other fields.

Good Sealing Performance: Reliable sealing structures, such as flexible pressure-activated sealing or circulating water channel cooling sealing, ensure that materials do not leak under high-pressure and high-temperature conditions, preventing contamination of the production environment and waste of materials.

Fast Screen Changing Speed: Equipped with an accumulator hydraulic station, the screen changing time is short, allowing for rapid completion of screen changing operations and ensuring high production efficiency.
