The mechanical grille decontamination machine can complete the successive cleaning, the full cross-section cleaning, high cleaning power. The girder lintel is supported on the concrete foundation, which makes the whole operation of the cleaning machine stable and reliable. The tooth rake pierces the grille to a certain depth, brings the dirt attached to the grille to the top of the decontamination machine, completes the flipping and unloading measures, and insists on cleaning the cross-section without dirt. When the sprocket of the transmission system rotates at a constant speed, the entire harrow chain moves from top to bottom, and it is separated from the liquid with solid debris. The fluid flows out through the gap between the harrow teeth, and the entire working condition is carried out one after another. Due to the layout shape of the rake teeth, when the rake tooth chain carries debris to the upper end for reverse movement, a relative self-cleaning movement occurs between the front and rear rakes, allowing the debris to fall by gravity, and a rotating cleaning brush can be set behind the equipment.

The advantages of the mechanical grille are high degree of initiative, high separation power, low power consumption, no noise, and good corrosion resistance. Under unattended conditions, it is possible to confirm continuous and stable operation, and an overload safety protection device is set up. When something goes wrong, it will automatically stop, which can prevent the equipment from overloading. This device can adjust the working distance of the device according to the user's needs and complete the periodic operation; it can be actively controlled according to the liquid level difference between the front and back of the grille; and has manual control function to facilitate maintenance.
