External Rotary Drum Screen performance and structure

The External Rotary Drum Screen is a device developed by our company for large-scale solid-liquid separation of sewage and biogas slurry with low solid content and high water content. The external Rotary Drum Screen shell is made of all stainless steel. It is supplied by the rotating drum solid-liquid separator manufacturer. The External Rotary Drum Screen has a large processing capacity and is specially designed for the separation of fine impurities. The screen specifications can also be customized according to the customer's processing materials. Adjust the screen density for gradual separation; suitable for the filtration of biogas residue and liquid, it is widely used and has a good treatment effect.

Automaticity of External Rotary Drum Screen

The External Rotary Drum Screen has a high degree of automation, strong decontamination ability, low power consumption, and fast separation of slag and liquid. After separation, the moisture content of the slag is between 50-60%, without clogging, External Rotary Drum Screen with automatic cleaning function, and after treatment The fecal and urine water solid content, chemical oxygen consumption, total oxygen consumption. The removal rate of ammonia and phosphorus can be between 65%-85%. The frame, screen, etc. of this series of machines are made of stainless steel and anti-corrosion treatment, etc., with high corrosion resistance, high strength, and long service life.

The technicality of External Rotary Drum Screen

First of all, the External Rotary Drum Screen uses a cutting sewage pump to prevent clogging. The external 304 stainless steel screen is cleaned with physical filtration afterward, and the solid-liquid separator is better. Secondly, External Rotary Drum Screen the addition of a micro vibrator to the screen prevents the particles from sticking to the screen out of the water tank and also makes it easier for the particles to flow into the trough. In addition, the use of post-processing technology and the use of fan blades at the discharge port prevent the accumulation of filter residue from blocking the discharge port. Finally, using motorized control, the low water level is automatically closed, and the high water level is automatically opened, saving labor costs.

The grid structure design of the External Rotary Drum Screen benefits

Quick screen change method: Easy to replace the screen, about 3-5 minutes to assemble;

External installation net structure (patented technology): high net tightness, long service life, other installation net structures of similar equipment 3-5 times.

Viscose structure: Adopt A and B glue for bonding, with high net tension, suitable for special requirements.

Spherical and cylindrical material trays of External Rotary Drum Screen: suitable for anti-clogging equipment that requires a spherical rubber structure. Cylinders of different materials are used. They can be selected according to the requirements of different industries. They are suitable for cleaning nets with fiber materials, etc., Can be used together with spherical.

Rolling brush cleaning of External Rotary Drum Screen: Brushes of different materials are used to clean clumped and sticky materials.

Ultrasonic cleaning screen of External Rotary Drum Screen: Ultrasonic generator and transducer are used to convert sound waves into vibration waves, which act on the screen to clean 200-500 mesh ultra-fine and difficult-to-screen materials.
