Unveiling the Working Principle of the Vacuum Suction Machine:
Unveiling the Working Principle of the Vacuum Suction Machine:
1. Harnessing the power of a vacuum pump or Roots blower, our machine creates a negative pressure airflow that adeptly draws material in from the feed inlet. Through precise separation by a separator, the material and gas are segregated, allowing the material to gracefully descend into the silo by its own weight.
2. Once the silo reaches its full capacity or the predetermined suction time, the vacuum pump halts. The internal pressure stabilizes, prompting the discharge valve to open, and the material is smoothly transferred into the storage container via the discharge port. During this phase, the compressed air bag on the filter activates, ensuring an automatic and thorough back-blow cleaning.
3. Post-discharge, the discharge valve automatically seals, initiating a seamless repetition of the entire conveying cycle.
