Rotary Vacuum Drum
Our disc thickener belongs to mature vacuum filtering equipment named Rotary Vacuum Drum. It realizes continuous slurry thickening via immersion adsorption, vacuum dehydration and air backblowing discharge. This machine features large filtration area and small occupied space, and the unique backblowing structure avoids frequent filter cloth clogging. It delivers stable high-concentration discharge for various fiber and slurry materials.
Detailed Description
As a core disc thickening device, this Rotary Vacuum Drum relies on gravity separation paired with vacuum extraction to finish low-density slurry concentration. Apart from conventional papermaking pulp thickening, this Rotary Drum Vacuum Filtration fits multiple industrial production lines: bamboo pulp processing workshops, recycled paper waste pulp recovery lines, agricultural fiber slurry dehydration stations, biogas residue solid-liquid separation projects and textile fiber waste treatment workshops. It is also well-received by small mineral mud concentration factories and herbal extraction residue dewatering production lines. The complete workflow of this Rotary Vacuum Drum goes through slurry feeding, disc adsorption, gravity draining, vacuum deep dewatering and air backblowing unloading. Multiple fan-shaped filter discs rotate slowly inside the tank, adsorb fiber materials to form filter cakes. When rotating to the vacuum area, residual moisture is fully drawn out to lift slurry density. At the discharging station, compressed air with scrapers strips finished cakes cleanly, effectively solving filter cloth blockage issues that trouble many similar dewatering machines. All separated clear filtrate can be recycled back into the production system to cut water consumption and production costs.
5 Google Independent Station FAQ
What types of raw slurry can this disc vacuum thickening machine process continuously?
A: It works well for paper pulp, recycled fiber slurry, biogas residue, herbal dregs and mineral mud with low initial concentration.
What design prevents the filter medium from frequent clogging during long-time running?
A: It adopts built-in compressed air backblowing structure matched with scrapers to thoroughly strip filter cakes off the cloth.
What two dehydration forces does this disc vacuum filtering unit utilize for slurry thickening?
A: It combines natural gravity draining and negative pressure vacuum suction to remove moisture from fiber cakes.
What advantage does this disc filtering equipment have over traditional thickening machines?
A: It has larger effective filtration area with smaller floor space, supporting stable 24-hour continuous production.
Can the separated filtrate liquid after filtration be reused in the production system?
A: Yes, the filtered white water is clean and can be fully recycled to lower overall factory water expenditure.
