Case study – Industrial Vacuum System for the collection of polyethylene filaments

Customer’s need

The polyethylene filaments the customer needs to manage are a type of residual waste that, if not properly removed, can accumulate, clogging machinery and causing malfunctions and production slowdowns.

Our Customized Vacuum Solutions

We have designed a customized suction system with two pre-separators that efficiently vacuum and dispose of large quantities of polyethylene filaments simultaneously.

To ensure a safe working environment, the system is equipped with an alarm function that alerts operators if they have to move away from machinery.

Safety system overview

To ensure operator safety, the discharge areas of the pre-separators are protected by two cages with gates. When a pre-separator is discharging or in operation, the gate locks, preventing entry for routine maintenance tasks. This status is visually indicated by a system of 4 flashing lights, with 2 above the separators and 2 in the discharge area.

• Pre-separator lights: red when the pre-separators are in operation, otherwise green.
• Discharge area lights: red when the pre-separators are operating, green when the pre-separators are neither operating nor discharging. When the light is green, the area is safe to access.
• When the light turns from green to orange, only 5 minutes remain before access is restricted, requiring personnel to vacate the area.
• If someone attempts to access the separators by opening the gates while the system is operating and the lights are red, a siren immediately sounds, and the entire system shuts down.

Through the control panel, it’s possible to set the operating time for each separator before they switch, e.g. 10 minutes. However, two electronic level sensors trigger an early switch, if one separator fills up too soon.
