Vacuum Tank in the Vacuum Forced Exhaust System of Extruder

In the vacuum exhaust system of an extruder, the vacuum tank is a crucial component. Here is a detailed introduction to it:

Structural Composition

1. Tank Body: Made of corrosion-resistant metal (e.g., stainless steel), cylindrical for strength and easy maintenance; size varies with extruder capacity.
2. Interfaces:
   • Exhaust inlet: Connects tovacuum venting device of extruder
   • Exhaust outlet: Connected to the vacuum pump
   • Sewage discharge port: Set at the bottom of the vacuum tank, used to discharge impurities, condensate, etc. accumulated in the tank.
   • Observation port: Transparent viewing window, optional
3. Internal Structure:
   • Baffle or deflector: separate gas from material particles.
   • Filter device: trap fine debris to protect the vacuum pump.

Functional Roles

• Stabilize vacuum degree:Acts as a buffer to maintain steady pressure despite fluctuating exhaust volumes.
• Gas-solid separation: Traps material particles via baffles/filters, preventing damage to the vacuum pump.
• Collect waste:Gathers condensate and impurities, drained periodically to keep the system clean.
• Reduce vacuum pump load:Ensures cleaner, steadier airflow, lowering pump strain and energy use.
