Vacuum Pyrolysis Cleaning Oven-Box Type
Product Description
Vacuum Pyrolysis Cleaning Oven is designed specially for cleaning polymers from a variety of metal parts. The parts to be cleaned are heated in a chamber where the polymer melts and drains into the bottom collector. Remaining polymer is vaporized and then water scrubbed in a water spray rubber where condensates are collected and rush out with water. Since cleaning takes place under vacuum, combustion does not occur. The parts are protected from excessive or localized high temperatures.
► APPLICATIONS
The Parts To Be Cleaned | Industry |
Spinnerets, Spinpacks, Filter Candles, Melt Pumps, Melt Pipes, etc. | Fiber (Chmeical fiber, Non-woven) |
Extruder Screws, Film Blowing Dies, Breaker Plates, etc. | Extrusion |
Hotrunner, Nozzles, Screws. etc. | Injection Molding |
Filters, etc. | Film |
► BENEFITS
- Cleaning is totally Automatic.
- Precise temperature control.
- Suitable for different thermoplastic polymers, e.g. PET, PA, PP, TPE, PB, PBT, PC, PMMA, ABS, etc.
- Short cleaning cycles (about 8 hours) and low energy consumption.
- Simple operation.
- Safety and no pollution.
► FEATURES
- Electric heaters – The electric heaters heats the chamber to 420°C-500°C which is depended on the kinds of polymers.
- Waste collector – The waste collector is for collecting the melting-down polymers from the shelf.
- Water Spray Rubber – The water spray rubber is for spray the off-gas out of the chamber.
- Built-In shelf – A heavy-duty structural steel shelf is included. The shelf rolls inside the oven onthe tracks, for ease of loading and unloading.
- Afterheater – The afterheater is for reheat the off-gas that out of the chamber preventing pipe blockage.
- Vacuum Pump – Vacuum pump is for create a vacuum chamber to prevent the parts to be cleaned from damage due to ignition in the oven.
- Safety & Controls – The Ovens include adual-element temperature sensor, water pressure safety interlock switch, Y-strainer, automatic solenoid valve.
- Control Panel – The Ovens come standard with a control panel, circuit breaker, control relays, interlocks, and terminal strips.
- PLC+Touch panel – Direct display the temperature rise curve, having all controls. (Optional)
- Catalyst – The generated off-gas out of the oven are converted to harmless water vapor and carbon dioxide in the catalyst. (Optional)
► CLEANING PROCESS
I. Melting Phase:
The parts to be cleaned are heated in chamber. Most of the polymer melts and drains into the bottom collector.
II. Pyrolysis Phase:
Polymer that did not melt during the first phase will be pyrolyzed and vaporized under vacuum. The generated gases are then water scrubbed in a secondary scrubber where condensates are collected and rush out with water.
III. Oxidation Phase:
Remaining ploymer that still exist after the pyrolysis phase will be burnt under vacuum and limited air.
