The irrigation head includes equipment and facilities such as inlet pump, power control cabinet, sand and gravel filter, automatic backwash laminated filter, automatic water and fertilizer integrated machine, pipeline and distribution control room, providing water source and meeting irrigation water and fertilizer needs.

1. Sand and gravel filter

Sand and gravel filter, also known as quartz sand filter or sand filter, is a filter that uses homogeneous quartz sand of equal particle size to form a sand bed as a filter carrier for three-dimensional deep filtration. It is commonly used for primary filtration. It mainly uses sand and gravel as filter media for filtration.

Sand and gravel filter is one of the media filters, and its sand bed is a three-dimensional filter with strong ability to intercept pollutants. It is suitable for deep well water filtration, agricultural water treatment, various water treatment process pretreatment, etc. It can be used in various places such as factories, rural areas, hotels, schools, horticultural fields, water plants, etc. Among all filters, sand and gravel filters are the most effective in treating organic and inorganic impurities in water. This type of filter has a strong ability to filter out and retain impurities, and can provide uninterrupted water supply. As long as the organic matter content in the water exceedsAt 10mg/L, regardless of the inorganic content, a sand and gravel filter should be used.

According to the irrigation project usage and filtration requirements, it can be used alone, in combination with multiple filters, or in combination with mesh filters or laminated filters. As a primary filter for mesh and laminated filters. Improve the filtration efficiency of mesh and laminated filters.

2. Automatic backwash laminated filter

The fully automatic laminated filter comes with an electronic control device that can control all steps of backwashing using time intervals and pressure differentials. Once set, it can be used for a long time. The automatic backwash filter completes the entire automatic backwash process within seconds without interrupting its operation. The backwash is automatically initiated by the set time or pressure difference signal, and the backwash valve changes the direction of water flow in the filtration unit. The spring on the filter element is

The water pressure is pushed open, and all the discs and small pores between them are released. The nozzle located in the center of the filter element sprays water along the tangential direction, causing the disc to rotate. Under the scouring of the water flow and the centrifugal force of the high-speed rotation of the disc, the objects trapped on the disc are washed out. Therefore, a very small amount of self use water can achieve a good cleaning effect. Then the backwash valve returns to the filtering position, and the spring on the filter element presses the disc again, returning to the filtering state. The backwash water is filtered by the system.

Accurate filtration, different precision filter discs can be selected according to water requirements, includingVarious specifications such as 20 microns, 55 microns, 100 microns, 130 microns, 200 microns, 400 microns, etc., with a filtration ratio greater than 85%.
