Single column hydraulic PET bottle recycling and granulation screen changer

The single-column hydraulic screen changer for PET flake recycling and granulation is a specially designed equipment for the process of recycling and granulating PET flakes. It enables rapid screen change without interrupting the production line, thereby ensuring the continuity and stability of production. Below is a detailed introduction to this screen changer:

I. Structural Composition

The single-column hydraulic screen changer for PET flake recycling and granulation primarily consists of essential components such as the main body, column, hydraulic cylinder, screen blocks, and safety guards. Two filtration channels are located on the column, housing the screen blocks. These screen blocks can alternately shift between the working position and the replacement position under the action of the hydraulic system.

II. Working Principle

The screen changer employs a dual-filtration-channel alternating operation mode. During normal operation, one screen block is in the working position, filtering impurities from the melt, while the other is in the standby position, ready to take over. When a screen change is necessary, the hydraulic device is activated, swiftly switching the positions, pushing out the dirty screen block and bringing the standby block into service, thereby completing the screen change process without halting production.

III. Advantages

Efficient Filtration: Utilizing specially designed screens, it effectively filters impurities from the melt, enhancing product purity and quality.

Non-Stop Screen Change: The unique dual-filtration-channel design allows for screen replacement without interrupting production, significantly boosting efficiency.

Easy Operation: The control system is user-friendly, ensuring swift mastery of operation by workers.

High Pressure & Temperature Resistance: Manufactured with high-quality materials and special processes, it exhibits excellent resistance to high pressure and temperature, suitable for harsh working environments.

Energy Saving & Environmental Protection: Its efficient filtration and non-stop screen change capabilities reduce waste and energy consumption during production, contributing to environmental protection.

IV. Application Scope

The single-column hydraulic screen changer for PET flake recycling and granulation is particularly suited for the recycling and granulation of PET flakes. Additionally, it can also be applied to the recycling and granulation of other plastic materials, such as PP, PE, ABS, and PS.

V. Configuration Options

The screen changer typically offers two configuration options:

Standard Configuration: Screen changer body + accumulator hydraulic power unit + heating device. This configuration meets most standard production requirements.

Custom Configuration: Screen changer body + accumulator hydraulic power unit + heating device + electrical control cabinet. This configuration provides a higher level of automation and more flexible control, suitable for scenarios requiring greater production efficiency and product quality.

PET extrusion screen changer

In conclusion, the single-column hydraulic screen changer for PET flake recycling and granulation is an efficient, stable, and easy-to-operate equipment that significantly enhances production efficiency and product quality in the PET flake recycling and granulation process.
