Product Introduction
The agricultural water-saving irrigation disc filter is a core device to ensure the efficient operation of the irrigation system. It can accurately intercept impurities in water, prevent irrigation equipment from clogging, and provide clean water sources for crops. It is widely used in agricultural irrigation, landscape greening and other fields.
Structural Design
- It adopts a modular design, and the filter units can be flexibly combined according to the flow demand, which is suitable for different irrigation scales.
- The main body is made of anti – ultraviolet aging engineering plastic or corrosion – resistant stainless steel, and the internal discs are made of food – grade PP or reinforced nylon, which is non – toxic, harmless and durable.
Filtration Principle and Back – Flushing Mechanism
- The filtering core is composed of multiple layers of discs. The grooves on the surface of the discs cross to form a filtering channel, and the filtration accuracy can reach 50 – 200 microns. When the water flows through the disc group, the impurities are intercepted, and the purified water flows into the irrigation pipeline.
- When the impurities accumulate and cause the pressure difference to increase, the back – flushing can be started manually or automatically. During back flushing, the water flow is reversed, the discs are loosened, and the impurities are discharged. The single back flushing only takes 30 – 60 seconds, with less water consumption. And partial units can be flushed without affecting the system operation.
Product Advantages
- High efficiency filtration: It can effectively intercept sediment, algae, etc., prevent drip irrigation tapes and sprinklers from clogging, and ensure the uniformity of irrigation.
- Strong adaptability: The filtration accuracy can be adjusted according to the water quality of the water source. For example, 100 – 200 microns can be selected for river water treatment, and 50 – 100 microns can be selected for well water treatment.
- Convenient maintenance: The discs can be disassembled, cleaned and reused, with a service life of 1 – 2 years. The structure is simple, and professional technical maintenance is not required.
- Small floor space: It can be installed at the head of the irrigation system and integrated with other equipment without occupying too much space.
Application Scenarios
- It is suitable for drip irrigation, sprinkler irrigation, micro – sprinkler irrigation and other systems, which can prevent drippers and sprinklers from clogging and meet the fine – irrigation needs of greenhouse seedling raising, flower planting, etc. It can also be used for head-end filtration of field flood irrigation or furrow irrigation to prolong the service life of pipelines. It is widely used in vegetable greenhouses, orchards, tea gardens, urban greening and other scenarios.
Technical Parameters (Example)
- Connection diameter: Multiple options are available, such as 2-inch, 3-inch, 4-inch, etc. (DN50, DN80, DN100, etc.).
- Maximum flow rate: According to different models, it can reach 25 – 64m³/h, etc.
- Filtration area: Some models can reach 1020 – 2040cm².
- Filtration accuracy: Usually, it can be selected between 50 – 200 microns, and some products can provide a range of 20 – 600 microns.
Installation and Usage Precautions
- Pay attention to the water flow direction during installation and install it according to the arrow indication.
- Wrap teflon tape at the connection to prevent water leakage.
- The water pump pressure should not be too high during the test – run to avoid damaging the filter.
- Regularly clean the filter discs, and combine automatic back – flushing with manual cleaning to ensure the filtration effect.
