Product Description:
Structural principle and application analysis of FLNJ inner inlet mesh plate fine grid and drum grid inner inlet mesh plate screen application FLNJ inner inlet mesh plate fine grid is suitable for solid-liquid separation process and can be widely used in municipal sewage, such as pretreatment process and advanced treatment process of new, reconstructed, water quality upgrading, technical transformation and updated sewage treatment plant; Structural principle and application analysis of fine screen of inlet mesh plate in industrial FLNJ and inlet mesh plate grid in drum grid.
purpose
FLNJ internal inlet mesh plate fine screen is suitable for solid-liquid separation process, and can be widely used in municipal sewage, such as pretreatment process and advanced treatment process of reclaimed water in new construction, transformation, water quality upgrading, technical transformation and upgrading sewage treatment plants; Industrial wastewater such as textile, papermaking and other processes and Laishui pretreatment process.
Structural principle
FLNJ self inlet mesh plate fine screen is composed of six parts: self frame, driving system, mesh plate system, backwashing system, slag removal system and electric control system.
The reduction motor drives the sprocket to rotate, and the sprocket drives the mesh plate to rotate continuously; The sewage enters the screen from the water inlet and is filtered by the mesh plate. After filtration, the water flows to the outside of the mesh plate. The sewage is intercepted on the inner surface of the same plate and brought to the top with the continuous rotation of the mesh plate; The backwashing system washes the outside of the washing plate. Under the action of washing water, the dirt is washed to the slag receiving tank and flows out of the sewage outlet together with the washing water.
1. Rack part
The main material is 304.
2. driving system
The drive sprocket adopts PA1010, which has excellent wear resistance and self lubrication, good rigidity, mechanical strength and medium stability. Its acid-base resistance, oil resistance and cold resistance are very good, ensuring its use in sewage environment. The guide rail is made of high molecular polyethylene, which has good wear resistance and self lubrication.
3. Screen system
The inner sleeve of the rotary wheel is a nylon injection molded part, and the outer sleeve adopts glue hanging treatment to improve the wear resistance. Since the glue layer has good elasticity. It prolongs its service life and protects the surface of the guide rail at the same time.
The chain plate is a polyethylene injection molded part with unique structural design. It can well seal with the end face of the guide rail during the rotation of the screen plate, so as to prevent dirt from entering the guide rail, resulting in filtered water pollution and wear of the guide rail. The mesh plate is the core component of the whole mesh grid. It adopts non-metallic injection molding parts to reduce the weight of the whole machine. At the same time, the modular design is conducive to the installation and maintenance of the mesh plate system.
Performance characteristics
1. High removal rate, which can effectively remove hair and other fibrous substances;
2. The backwashing water will completely remove the dirt trapped on the screen plate and will not fall into the filtered water to avoid secondary pollution;
3. The mesh plate adopts non-metallic injection molding parts, which are wear-resistant and corrosion-resistant;
4. Underwater transmission parts are not set, so there is no need for maintenance, which is more convenient for overhaul and maintenance;
5. Easily worn parts are fully standardized, easy to replace and easy to operate;
6. Stable operation, light vibration and low noise.
