The working principle of this equipment consists of a cover, drum assembly, collection tank, transmission device, flushing device, slag plate, and frame, among other components. When the drum filter operates, the reducer drives the grid frame to rotate. The floating matter in the wastewater is filtered and intercepted on the grid screen and then transferred to the slag plate by the rotating grid frame where the slag falls off. At the same time, the flushing device is used to backwash the grid surface, and the washed slag falls onto the slag plate, sliding into a garbage cart or conveyor for external transportation. The mesh cylinder rotates under the drive of the transmission device, and the wastewater enters the distribution trough from the inlet pipe, then evenly overflows from the outlet. The solid substances in the wastewater that fall on the outer wall of the rotating mesh cylinder are intercepted by the mesh screen, while the water flows out through the mesh gaps into the collection pool. The solid substances intercepted by the mesh cylinder are automatically removed from the outer wall of the screen by the scraper machine. The continuous rotation of the mesh cylinder allows the solid substances attached to the outer wall of the screen to quickly separate from the cylinder, thereby improving production efficiency. The backwashing system consists of flushing pipelines and nozzles. High-pressure water is sprayed onto the mesh cylinder at high speed in a fan shape through the nozzles, quickly washing away the solid substances attached to the mesh cylinder to form a continuous, unobstructed filtration area. This filtration equipment is characterized by high efficiency, large processing capacity, and fine filtration.

In modern industrial production, high efficiency, energy saving and wide application are important criteria for evaluating the performance of a device. The rotary drum filter, with its unique design concept and excellent performance, stands out in this field and has become an indispensable solid-liquid separation equipment in many industrial fields.
The high efficiency of the rotary drum filter is first reflected in its filtration speed. Through the rotation of the drum, the liquid can quickly pass through the filter medium to achieve continuous and efficient filtration operation. This design not only improves production efficiency, but also significantly reduces the waiting time in the production process and reduces energy consumption. At the same time, the rotary drum filter adopts energy-saving design, such as optimizing the transmission mechanism and reducing unnecessary mechanical movement, which further reduces the operating cost and meets the requirements of modern industry for energy conservation and emission reduction.
The non-clogging design of the rotary drum filter is also an important manifestation of its high efficiency and energy saving. When dealing with high-concentration suspensions or viscous liquids, traditional filters are often prone to clogging, resulting in reduced filtration efficiency or even downtime for maintenance. The rotary drum filter can effectively prevent the occurrence of clogging through its special filtration mechanism and backwashing system, maintain stable filtration performance, and reduce downtime and maintenance costs caused by clogging.
The application field of rotary drum filter is extremely wide, covering almost all industrial fields that require solid-liquid separation. In the environmental protection and water treatment industry, the rotary drum filter is a powerful assistant for treating industrial wastewater, domestic sewage and suspended solids and particulate matter in various water bodies. Through its efficient filtering effect, the water quality can be significantly improved to meet the discharge standards or reuse requirements.
In many other industries, the rotary drum filter also plays an important role. In the petrochemical industry, it can effectively remove impurities in the oil-water mixture and achieve oil-water separation; in the food and beverage industry, it can improve the clarity and quality of products such as juice and dairy products; in the textile printing and dyeing industry, it can reduce the color and turbidity in the wastewater and achieve the discharge or reuse of wastewater in compliance with standards; in the papermaking industry, it can improve the purity and quality of pulp and reduce production costs.
The rotary drum filter has become an indispensable solid-liquid separation equipment in modern industry with its high efficiency, energy saving and wide application. It not only improves production efficiency, reduces energy consumption and operating costs, but is also widely used in multiple industrial fields, providing strong support for the sustainable development of various industries. With the continuous advancement of technology and the continuous expansion of the market, rotary drum filters will play a more important role in the future and contribute more to the greening and intelligence of industrial production.
