[Overview]

The rotary drum fine grid cleaning machine is a result of introducing digestion technology, improving and innovating, and is widely used in urban domestic sewage treatment, industrial wastewater treatment, food wastewater treatment, and papermaking wastewater treatment projects. The rotary fine grid machine can extract finer floating particles, suspended solids, and sediments from sewage, and discharge them after transportation and pressing.
The rotary fine grid cleaning machine is exquisitely designed, compact in structure, and all components are made of stainless steel material, without high-speed moving parts.
The rotary drum grille is fully automatic controlled, with smooth operation, low energy consumption, low noise, and a small gap of only 1-5mm in the rotating grille. With the help of fluid guidance, the separation efficiency of the equipment is greatly improved. The entire rotary drum fine grille machine can achieve self-cleaning of the grille gap during equipment operation. Equipment for non-destructive treatment of sand, gravel, debris, and hard objects, with a drum type fine grid machine that never clogs.
The drum type grating machine is installed in the water channel at a 35 ° angle to the horizontal plane. Sewage flows into the drum type grating from the end of the drum type grating, and flows out through the grating gap on the side of the grating. The grating traps suspended solids, floating objects, etc. in the water in the drum. The drum type grating rotates at a speed of 4.6r/min, and there are nylon brushes and flushing water nozzles above the drum type grating machine to remove the slag from the grating gap. At the same time, it is conveyed by screw and squeezed for dehydration. Finally, the material falls into the garbage bin or conveyor through the discharge port at the upper end of the drum type grating and is transported outside.

[Features]
1. The rotary fine grid machine forms an angle of about 35 degrees with the water flow, and due to the formation of the baffle, even many pollutants smaller than the grid gap can be separated by the rotary drum fine grid machine.
2. The rotary fine grid machine is equipped with a flushing device and has a self-cleaning function.
3. The cylindrical structure increases the flow rate of the rotating grid machine compared to traditional grids, reduces head loss, and reduces the stacking plane in front of the rotating grid machine.
4. All parts of the drum grille that come into contact with water are made of stainless steel and have undergone acid pickling and passivation treatment; The rotary drum fine grid machine is suitable for domestic sewage and most industrial water, with strong anti-corrosion performance and long service life.
5. By integrating the salvaging, conveying, and pressing processes of the rotary drum fine grid machine, the rotating fine grid machine not only saves floor space but also reduces the subsequent processing costs of garbage.
6. The rotary drum fine grid machine requires almost no maintenance, and there is no need to add oil to the rotating point. The driving device requires very few refueling times.
