Vacuum drum device

Working:

Vacuum drum filter equipment is mainly used for liquid waste treatment diatomaceous earth, hence called diatomaceous earth waste treatment device. The device is driven by the reducer filter continuous uniform rotation of the drum by a vacuum pump pressure difference formed by the filter drum within the dispenser, the flow through the filter material was filtered off with suction, the water in the feed solution was continuously sucked into the discharge or recycle tank; and solid materials (such as diatomaceous earth) is uniformly adsorbed on the outer surface of the drum forming a cake layer, when the layer reaches a certain thickness of the filter cake, through the discharge zone blade automatic feed, and the feed to the cutting blade position of the layer cake, the solid material was cut to take a continuous chute in the bag handle. This cycle, continuous suction filtration operation, the water discharge of waste residue and require separate treatment, to environmental protection, health requirements.

Configuration or composition:

★ Diatomite waste tank;

★ Mixing tank (with agitation);

★ Drum filter, unloading bodies and chassis;

★ Buffer tank;

★ Pump: filtrate pumps, centrifugal pumps, vacuum pumps;

★ Valves, pipe fittings;

★ Control system.

Main features:

★ Integrated filter drum is easy for evenly pre-coating and washing

★ Backwashing function guarantees the cleaning for inside to outside

★ Labor intensity is low due to continuous autornatic operation

★ Different moisture filter cake can be formed through controlling the speed by frequency converter

★ Compact construction covers a small area,that is more simplified,stable and reliable

Control system:

The system uses PLC programming automatic control, touch screen panel settings can be realized precoat filtration process automatic control, can automatically be adjusted according to the blade feed material liquid filtration efficiency filtration with automatic protection function scraper stroke, liquid-liquid filter material bit automatic control, automatic suction filtered material control functions. Control device includes a vacuum drum filter, waste diatomite tank, solid-liquid pumps, waste soil and waste soil stirred tank tank top and bottom level control.
