Grille, also known as steel grating, steel grating or grating plate, is welded from flat steel and twisted steel. Grille is mainly used in resting paths, walkways, ditch covers, and step boards. It is also used in environmental protection equipment and sewage treatment, and is increasingly being widely used due to its superiority.
The width of the empty space between the grid bars can be set according to the method of removing dirt and the requirements of the water pump. The manual removal of the grid open space is generally 16-25mm. The grille in front of the sedimentation tank or sedimentation tank is generally 15-30mm, with a maximum of 40mm. There are three types of commonly used mechanical cleaning equipment, namely chain type, mobile type, and steel wire rope traction grid cleaning machines.
According to the size of the spacing between the grid bars, the grid can be divided into three categories: coarse grid, medium grid, and fine grid. According to the cleaning methods of the grid, there are three types: manual grid, mechanical grid, and hydraulic eradication grid. According to the different characteristics of the grid structure, it can be divided into various forms such as grabbing rake type, circulating type, curved type, rotary type, drum type, rotary type, toothed rake type, and stepped type. Grille equipment is generally used on the inlet of sewage treatment or at the inlet of the collection tank of the progressive pump station. Its primary function is to remove large suspended or floating substances in sewage, reduce the treatment load of subsequent water treatment processes, and maintain water pumps, pipelines, and surfaces. When the amount of blocked slag exceeds 0.2m3/d, mechanical slag cleaning method is generally used; When the amount of slag in the grid is less than 0.2m3/d, manual or mechanical cleaning methods can be used. The application of grilles has a wide range of applications in construction, planning and decoration, sewage treatment, engineering applications, and other fields.
Fiberglass grating can be used as a drainage board in car wash rooms, as well as as as a cover plate for urban street gutters. Due to the unique hollow nature of the grating, it can easily drain water, and the fiberglass grating can also see the situation under the gutter. Therefore, the grating is a high-quality material used as a drainage board. Different types of grilles have different materials and can be customized according to needs. Nowadays, there are mainly two types of grilles: iron grilles and fiberglass grilles. The difference lies in the fact that iron grilles will corrode, rust, and oxidize under long-term erosion by wastewater. Iron products are not moisture-proof or resistant to acid and alkali, and there are corrosive elements in wastewater that can corrode iron grilles. Moreover, the grilles will have safety hazards after prolonged corrosion, requiring timely repair and inspection. Therefore, maintenance costs are high in the later stage, and iron grilles are mostly black in color, Even if painted in other colors, it will fall due to corrosion. After all, the iron grille was briefly stolen, so it was once again thrown away. Fiberglass grating overcomes various shortcomings of iron grating, and it is lighter and simpler in construction than iron grating. It has a variety of colors to choose from freely, and is resistant to corrosion, oxidation, acid and alkali. It is safe and effective without maintenance in the later stage, and can be completed in one step. Fiberglass grilles are not easily thrown away.
The fiberglass grille used in the car wash room undergoes prolonged car washing and brushing, and wastewater flows from the car body onto the fiberglass grille in the car wash room. After passing through the hollow fiberglass grille, it is discharged into the underground drainage ditch. Over time, the grille does not show any signs of corrosion, oxidation, or whitening. The fiberglass grille in the car wash room shows its original characteristics even more after being washed, with no color change, no falling blocks, or cracks, These are enough to prove the excellent technology of our company's car wash room fiberglass grille. The specification for the fiberglass grille used in the car wash room in the car wash shop is 38 * 38 * 38, which is a specialized grille for the car wash room. The weight per square meter is 19.5 kilograms, exceeding approximately 3.5t-4 tons per square meter in the city.
