Function
The bar screen is an important front-end sewage blocking device in sewage treatment.
Suitable for water supply and drainage pump stations, urban sewage, industrial wastewater, etc., used as both coarse and fine screens.
The rake teeth made of nylon or stainless steel are assembled on the chain shaft in a certain arrangement order to form a closed circular tooth rake chain.
The entire rake tooth chain is driven by the drive sprocket and moves continuously from bottom to top, conveying the suspended solids intercepted on the rake teeth from the sewage to the ground or above the platform, and removing the materials during the rotation and meshing of the rake teeth, To achieve the purpose of protecting the water pump and reducing the processing load of subsequent processes.
Advantages

(2)Not easy to be blocked
(3)Easy to clean and maintance
(4)Effective solids removal
(5) Long life and durability
(6)High degree of automation
(7)Low power consumption
(8)No noise
(9)Good corrosion resistance
Range Of Application
- Wastewater Treatment Plants: Bar screens are an essential part of the preliminary treatment stage in both municipal and industrial wastewater treatment. They prevent large objects from entering the primary sedimentation tanks, biological treatment processes, and other subsequent treatment units.
- Industrial Intake Structures: In industries such as power plants, pulp and paper mills, and food processing plants that use large amounts of water, bar screens are used to protect the intake pumps and other water - handling equipment from damage caused by debris. They ensure a continuous and clean water supply for the industrial processes.
- Stormwater Management: In stormwater treatment facilities, bar screens are used to remove debris carried by storm - water runoff. This helps to prevent clogging of downstream storm - water drainage systems and also protects the receiving water bodies from the influx of large amounts of solid waste.
It can be widely used in urban sewage treatment, tap water industry, power plant inlet, and can also be used as a front-end screening equi[mentin wastewater treatment processes in industries such as textile, food processing, papermaking, leather, etc. It is currently one of the most advanced solid-liquid screening equipment.
