Introduction
The rotary grille decontamination machine is a special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment. In the tap water industry and power plant water inlet, it can also be used as a pre-screening equipment in wastewater treatment processes in textile, food processing, papermaking, leather and other industries. It is one of the most advanced solid-liquid screening equipment at present. The rotary grille decontamination machine is composed of a unique rake tooth assembled into a set of rotary grille chains. Driven by the motor reducer, the tooth chain rotates against the direction of the water flow. When the tooth chain is moved to the upper part of the equipment, due to the guidance of the groove wheel and the check rail, a relative self-clearing movement occurs between each set of teeth, and most of the solid materials fall by gravity. The other part relies on the reverse movement of the cleaner to clean the debris stuck on the handle teeth.

Structure and composition
The mechanical grid decontamination machine is mainly composed of a frame, a driving device, a tooth handle and a transmission chain. Specially shaped handlebar teeth made of ABS engineering plastic nylon 6, nylon 1010 or stainless steel are assembled on the handlebar shaft in a certain order to form a closed handlebar tooth chain. The underwater grid (handle teeth) intercepts the dirt and moves up the rail. When it reaches the top, due to the guiding effect of the curved rail and gears, a relative movement occurs between adjacent rake teeth, pushing the dirt out and unloading it according to its own weight. into the waste container. At the same time, the special rotating brush removes the trace residual dirt on the rake teeth.

working principle
The grid decontamination machine is a special sewage treatment equipment that can continuously and automatically block and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment. The grille decontamination machine is a special-shaped rake tooth made of ABS engineering plastics, nylon or stainless steel. It is installed on the rake tooth shaft in a certain order to form a closed rake tooth chain. The lower part is installed in the water inlet channel. Driven by the transmission system, the entire rake tooth chain moves from bottom to top, and separates the solid debris from the liquid, while the liquid flows through the grid gaps of the rake teeth. Driven by the motor reducer, the rake tooth chain performs a reverse movement against the direction of the water flow. When the rake tooth chain reaches the upper part of the equipment, due to the guidance of the sheaves and curved rails, a relative self-cleaning movement 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 cleaner to clean the debris stuck on the rake teeth. The rake tooth chain is similar to the grid according to the direction of water flow. The rake tooth space installed on the rake tooth chain shaft can be selected according to the use conditions. When the rake teeth separate the solid suspended matter in the fluid, it can ensure the smooth flow of water. The entire operation process is continuous or intermittent.
Product advantages
1. High degree of automation and high separation efficiency, which can ensure continuous and stable operation without supervision.
2. Low power consumption, no noise, and good corrosion resistance. The machine body is equipped with a mechanical overload safety protection device to avoid overloading the equipment and damaging equipment components.
3. The working interval of the equipment can be adjusted arbitrarily to achieve periodic work.
4. The start and stop of the equipment can be automatically controlled based on the liquid level difference before and after the grille; and it has manual control function.
Used to facilitate maintenance.
