Screen type ladder grille decontamination machine/WJG plate-type Step Grille

Application

■ As it has good adaptability to and removal effect of fine particles and fiber waste contained in sewage, it is widely applied in the upgrading reconstruction, reinforced pre-treatment technological processes of sewage treatment plants.


Advantages

■ Adopt step-type punching plate design, have large filtering area, easily retain contaminants, and have high filter efficiency;

■ Be especially strongly adaptable to fiber wastes;

■ Adopt the box-plate-type structure, have firm structure and high symmetry, operate stably and be easy to install;

■ In the structure design, fully consider about the sewage environment and heavy-duty drag chain as the driving body of the filter plate;

■ Have no underground bearing structure, greatly reduce the underground failure probability, and operate more reliably;

■ Adopt high-efficiency brush and back-wash devices to unload contaminants and ensure the effective regeneration of filtering surface;

■ Adopt the front and back closed construction on the top, directly connect with the grille slag conveyor, and improve the working environment;

■ The equipment can be under full-automatic operation control according to the water level difference or at regular time to reach the best energy-saving effect;


Grille Breadth B (mm)600~3000
Suggested Grille Breadth B1 (mm)B+100
Effective Filtering Surface Breadth (Plate Breadth) B2 (mm)B-150
Suggested Grille Well Height H (m)1.5~10
Installation Angle (°)60~75
Common Aperture Diameter (mm)3,5,6,8,10
Plate Operation Velocity (m/min)~3.8
Main Driver Power (kW)0.75~3.0
Cleaning Brush Power (kW)0.37~0.75
Washing Water Pressure (MPa)≥0.3
The Designed Maximum Water Level Difference (m)1.0
Unit Discharge Capacity (Reference)Aperture: ≤3700
(m3/m2.h)* (Water Velocity)Aperture: 4~6900
0.8m/s, Effective Water Depth 1m)Aperture: 7~101200

The technological calculation process is as follows:

■ Discharge capacity (m3/h) = Unit discharge capacity (m3/m2. h) × Effective discharge area (m2)

■ Effective discharge area (m2) = Effective water depth (m) × Effective filtering surface breadth (m)

■ Effective water depth (m) (the design well water velocity is 0.8m/s) = Grille water depth (m) – Water head loss (m)

■ The reference values of water head losses are shown in the table below:

Water Head Loss of Grilles with Different AperturesAperture: ≤3mm0.6
Loss Reference Value (m)Aperture: 4~6mm0.5
(Water Velocity 0.8m/s)Aperture: 7~10mm0.4
