In the pre-treatment process of municipal sewage, industrial wastewater, rainwater treatment and other systems, the grid cleaning machine is the "first line of defense" to intercept solid impurities. If floating and suspended solids in the sewage are not effectively removed, it is easy to block subsequent water pumps, pipelines and reactors, leading to system failure and shutdown, and increasing maintenance costs.Rotary rake grille cleaning machineBuild a strong safety barrier for the stable operation of water treatment systems.

The primary highlight of the grille cleaning machine is continuous and efficient cleaning and precise interception. The equipment adopts a rotary chain transmission structure, and the spacing between the grid bars can be flexibly selected according to the size of impurities, which can accurately intercept solid impurities of different particle sizes. By driving the chain with a motor, the rake teeth circulate and scrape off the trapped impurities deep into the gap between the grids. Then, they are transported to the discharge port through a dirt guide plate, achieving an integrated continuous operation of "interception scraping conveying", with a cleaning efficiency of over 98%, without the need for frequent manual cleaning. For example, at the inlet of municipal sewage treatment plants, the grid cleaning machine can operate continuously for 24 hours, intercepting 1-5 tons of solid impurities per day to avoid clogging the lift pump with impurities such as plastic bags and cloth strips; In the treatment of food processing wastewater, fine spacing grids are used to effectively intercept large amounts of food residues in the water, preventing them from entering the biochemical pool and affecting microbial activity.

Secondly, stable and durable design with low maintenance reduces operational hazards. The key components of the equipment are made of high-strength materials: the grille strip is made of 304/316L stainless steel, which is corrosion-resistant and wear-resistant, with a service life of more than 10 years; The chain is made of wear-resistant alloy steel material, which has undergone surface carburizing treatment, with high tensile strength and a failure rate of less than 1% during operation; The rake teeth are made of nylon or stainless steel material, with good flexibility and not easily deformed, which can avoid scratching the grille strip. At the same time, the equipment is equipped with an automatic overload protection device. When the rake teeth encounter a hard object blockage and the chain tension exceeds the set value, the motor automatically stops and alarms to prevent damage to mechanical components; Some models adopt a waterless bearing design to avoid bearing corrosion caused by sewage immersion. The maintenance cycle is extended to 6-12 months, reducing maintenance workload by 50% compared to traditional grid cleaning machines.

In terms of intelligence and adaptability, the detailed design of the rotary rake grille cleaning machine conforms to the pre-treatment requirements. Support multiple control methods, including timed control, liquid level difference control, and remote control: liquid level difference control can automatically start cleaning based on the water level difference before and after the grille, avoiding ineffective operation and saving energy and consumption; After connecting to the automation system of the water plant, real-time monitoring of equipment operation status and cumulative pollution removal amount can be achieved, which is convenient for operation and maintenance management. Provide different installation forms and width specifications for different treatment scenarios, suitable for small community sewage stations and large municipal sewage treatment plants; In addition, the equipment is equipped with a flushing device that can regularly flush the grille and rake teeth to prevent impurities from adhering and ensure stable interception efficiency.

From the pretreatment of municipal sewage to the interception of impurities in industrial wastewater, and then to the cleaning of garbage in the rainwater pipe network, the rotary rake type grille decontamination machine has become the guardian of water treatment systems with "high efficiency, stability, and low consumption" as its core. Choosing a high-quality grille cleaning machine is not only a safe choice for subsequent treatment processes, but also a key step in reducing system maintenance costs and improving water treatment efficiency, providing a solid guarantee for the stable operation of the water treatment industry.
