The importance of sand filter system in sand production line
If sand production line manufacturers want to take the lead in the increasingly fierce competition, their primary problem is to improve the quality and technical content of their existing equipment.
The sand and gravel filter manufactured according to the needs is more effective in treating organic and inorganic impurities in the water, has a strong ability to filter out and retain impurities, and can provide uninterrupted water supply. The unfiltered water enters the tank from the upper part of each tank. It must be ensured that the water body spreads evenly in the filter, and then the clean water in each tank is collected into the main pipe and sent to the irrigation system, and then collected from the bottom. The device collects these clean water. When the sand filter is in the normal filtering state, the evenly-balanced filter material is collected to the bottom of the tank under the action of water pressure, in the plan of the sand filter.
Sand and gravel filter water collection device in sand production line: It has two forms, one is made of resin mixed material, so it is called “block water collection device”; the other is composed of many parts of anti-rust pipe It can be called a “tubular water collection device”. The local water head loss is very small. The block water collection device is made of mixed granite nitrate and epoxy resin. Its particle size range is 12-19mm. The surface area of the pores is large, and the filling thickness of this layer is not less than 7. The sand-gravel filter generally adopts a tubular water collection device, which is durable and easy to maintain. Counting from the top of the tubular catchment device, the bottom of the filter tank should be filled with a layer of granite gravel. The results of the confluence in the filtering state and the evacuation of the water flow in the recoil state are good, and the sand filter of the tubular catchment device is adopted.
