External inlet drum grid is a device used to remove solid particles and impurities in sewage treatment. Its working mechanism consists of the following steps:
1.Water Inlet Stage:
The pump transports the effluent from the inlet pipe to the inlet tank of the drum grid. Baffles or distribution pipes are used to distribute the effluent so that it flows evenly to the front of the grating drum surface. The effluent passes through the grating and flows into the bowl, where it flows out from the lower part of the bowl.
2.Filtration and Solid Particle Separation:
Suspended solids and solid particles in the effluent remain on the rotating drum surface. As the drum surface rotates, these solid particles move from the inlet end to the discharge end at the other end.
3.Unloading process:
The discharge mechanism is responsible for removing the solid particles trapped on the drum surface. This mechanism usually removes or removes solid particles from the equipment to keep them working efficiently.
Reasons for selection and areas of application:
Drum design and filtration area: The drum design is conducive to increasing the filtration area and improving the filtration efficiency, so that it has a remarkable effect in fine filtration.
Features of the wedge grid: The wedge grid is easy to pass through and is not prone to clogging, helping to ensure continuous operation of the equipment and reducing maintenance costs.
Automatic continuous operation: The equipment can run automatically and automatically discharge the slag, reducing manual intervention, and is suitable for long-term operation and unattended environments.
Material and design: The stainless steel material and fully enclosed design help to prevent secondary pollution, maintain the cleanliness of the effluent, and are suitable for occasions with high water quality requirements, such as fine filtration or industrial screening process for sewage pretreatment.
As a result, outflow drum grids are suitable for wastewater pretreatment or industrial screening processes that require high efficiency, continuous operation and fine filtration due to their design features and automation capabilities.
