Mechanical Fine Screen Description
The fine grille decontamination machine is assembled into a set of rotary grille chains by a unique rake tooth factory. Driven by the motor reducer, the rake tooth chain rotates against the direction of the water flow. When the rake tooth chain runs to the upper part of the equipment, due to the guidance of the sheave wheel and the curved rail, a relative self-cleaning motion occurs between each group of rake teeth, and most of the solid materials fall down by gravity. The other part relies on the reverse movement of the sweeper to clean up the debris stuck on the rake teeth. According to the direction of water flow, the rake tooth chain is similar to the grille, and the rake tooth gap assembled on the rake tooth chain shaft can be selected according to the usage conditions. When the rake teeth separate the solid suspended matter in the fluid, the water can flow through it smoothly. The whole working process is continuous or intermittent.
Mechanical Fine Screen Composition
Parts of the fine grille of the inner inflow mesh plate frame；
Drive System；
Stencil System；
backwash system；
Division system and Electronic control system;
The geared motor drives the sprocket to rotate. The sprocket drives the mesh plate to rotate continuously; the sewage enters the grille from the water inlet, and passes through the mesh plate to overspeed. The water flows to the outside of the screen plate, and the dirt is left on the inner surface of the same plate. With the continuous rotation of the screen plate, it helps to the original part: the backwash system flushes the outside of the screen plate, and the dirt is washed to the receiving channel under the action of the flushing water. Feel free to check the flushing water from the well to the sewage outlet.

Mechanical Fine Screen Advantage
Adopting stepped punching mesh plate design, large filtration area, easy retention of dirt, high filtration efficiency; especially strong adaptability to fibrous waste;
The box-plate structure is adopted, the whole machine is firm in structure, high in symmetry, stable in operation and simple in installation;
The sewage environment is fully considered in the structural design, and the heavy-duty traction chain is used as the transmission main body of the filter plate; there is no underwater bearing structure, which greatly reduces the probability of underwater failure and makes the operation more reliable;
Adopt high-efficiency rotating brush and backwash device to help remove dirt and ensure effective regeneration of filter surface;
The upper part adopts a front and rear closed structure, which is directly connected with the screen slag conveyor to improve the use environment;
Fully automatic operation control can be carried out according to the water level difference or timing to achieve the best energy saving effect.

Mechanical Fine Screen Application
It is a high-efficiency fine grille decontamination equipment that combines pollution blocking and decontamination. It is suitable for large, medium and small pump stations as fine grilles to intercept and remove floating objects in the water, such as: weeds, paper, cigarette butts, melon seeds, fibers, hair, etc. This model has a high dirt capture rate , the effective implementation of the subsequent treatment process.
