1, high chain mechanical grille
Features: Small floor space. Because the transmission part is above the water surface, the structure is relatively simple and the manufacture and maintenance are convenient. Disadvantages are that sundries are easy to get stuck between the chain and sprocket, and the sleeve roller chain has high cost and poor corrosion resistance. Scope of application: this grille is suitable for deep pools, such as sewage collection deep wells. The removal effect of impurities such as long fibers and ribbons in sewage is particularly good.
Step 2 rotate the grille
Features: compact structure, small volume, light weight, stable operation and convenient maintenance; Manual intermittent operation and automatic continuous operation can be realized. Its disadvantages are that it needs to be equipped with a circular grille, which is difficult to manufacture, and the equipment occupies a large area, and the removal effect of small particles and impurities is poor. Scope of application: This grille is suitable for the pollution prevention and control of large particulate matter with various pool depths and water depths.
Step 3 rotate the grille
Features: good decontamination effect, high degree of automatic separation of solid and liquid, and small equipment area. The disadvantage is that it is difficult to manufacture and install. Scope of application: This kind of grille is generally used in deep pools and shallow pools. It is suitable for removing impurities of various shapes in sewage.
4.I-type stepped mechanical grille
Features: The grille has good decontamination effect, stable operation and convenient maintenance, but the equipment occupies a large area. Scope of application: This grille is generally suitable for large-scale urban sewage treatment plants.
5. Arc grille
Features: the equipment occupies a small area, runs stably and is easy to maintain. The disadvantage is that the removal effect of small particle impurities is not good. Scope of application: this grille is suitable for the inlet channel of shallow pool.
6. Arc mechanical grille
Features: simple structure, convenient installation and use, and high working efficiency. The disadvantage is that it is difficult to manufacture circular grids. Scope of application: this grille is suitable for shallow pools of small and medium-sized sewage treatment plants or pumping stations.
7. Box-type rotating grille
Features: the grid does not need to build a special grid well, and the equipment is easy to move. The disadvantage is that it is difficult to manufacture and the effect of removing small particle impurities is not ideal. Scope of application: This grille is suitable for removing coarse particles and suspended solids in small and medium-sized sewage treatment projects. Usually placed in the pipeline of the treatment process system.
8. Channel rotating grille
Features: the grille is easy to install and the driving effect is stable. The disadvantage is that it is difficult to manufacture and maintain. Scope of application: This grille is suitable for sewage treatment projects with medium or small water volume, and is generally placed on the intake channel of the water collection tank.
