(Summary description)The filter is an indispensable filter device in the farmland irrigation system. The impurities in the water are mainly divided into physical impurities, chemical impurities, and biological organic impurities. It is necessary for practical use in the field, especially in the case of large areas. In some small areas In the drip irrigation system of three or two acres, many growers do not directly install the filter device. Many farmers say that the drip irrigation belt is replaced once a year and will not be clogged, but long-term use will also have a great impact on the supervisor. What filter equipment are currently available at home and abroad ? Let's briefly introduce it next.

Tell everyone about the common types of filters

The filter is an indispensable filter device in the farmland irrigation system. The impurities in the water are mainly divided into physical impurities, chemical impurities, and biological organic impurities. It is necessary for practical use in the field, especially in the case of large areas. In some small areas In the drip irrigation system of three or two acres, many growers do not directly install the filter device. Many farmers say that the drip irrigation belt is replaced once a year and will not be clogged, but long-term use will also have a great impact on the supervisor. What filter equipment are currently available at home and abroad ? Let's briefly introduce it next.

  一. Gravel filter

The sand filter is used in the drip irrigation system of large-scale cultivated farmland that uses surface water to irrigate. It is generally composed of two or more filter tanks, which are connected in parallel through the piping of the water outlet to form a filter station. As the filterable organic impurities, there are algae, moss and some bacteria. As with other organisms, it is best to use lake water for filtration, and it is best to choose a sand filter, which is a good filter for large areas.

  二. Centrifugal filter

The centrifugal filter uses the principle of centrifugal force to rotate the water and separate the sand from the water. If selected reasonably, the system has a constant working flow and the sand separator has a good sand removal effect. It is mainly used in irrigation water with high sand content. Northwest China This filter is commonly used.

   Generally, gravel filters are used as initial filtration, and then mesh filters are used as secondary filtration to extend the cleaning cycle of sand filters.

  三. Grid filter

The mesh filter is effective for the treatment of inorganic impurities such as silt and sand in the water. The water mesh filter with more organic impurities is generally not effective. The filter is different from the gravel filter and cannot store a large amount of organic impurities. It is generally used as a secondary Filter to use.

  4. Stacked filter

The laminated filter is a filter between the grit filter and the mesh filter. A large number of thin circular laminated bodies are used to overlap. After tightening, a cylindrical filter element is formed. Water passes between the laminated bodies and the impurities remain in the filter. In the tank, the stacked filter is currently used in large quantities throughout the country, with manual, semi-automatic, and fully automatic cleaning, and its filtering capacity is between the 20th and 400th holes.

  5. Y-type filter

For water containing sand and other debris, these impurities will damage valves, pump impellers and other system components of drip irrigation. A variety of Y-type filters are often used to treat these impurities, and they are generally installed downstream of the filtration system as secondary filtration. It can be installed at the front end of the branch pipe in the field to prevent the capillary from clogging.
