The grid cleaning machine is an ideal equipment for separating floating, settling, and suspended solids in urban sewage treatment and industrial wastewater treatment processes. Widely used in solid and liquid separation, cleaning, transportation, and dehydration in urban domestic sewage and industrial wastewater treatment projects. Compact structure, made of almost all stainless steel, with sufficient corrosion resistance and strength, can withstand harsh environments for a long time; Smooth low-speed operation, low energy consumption, low operating noise, large filtration area, and small hydraulic loss; The angle between the grille and water flow is about 35 degrees, even if the thickness is smaller than the grille. Many separable pollutants can be separated, and the functions of collection, transportation, and pressure are integrated. The compact structure reduces the subsequent processing cost of garbage, making it a new and efficient grid cleaning machine.
