The Qiancheng brand_type filter is a form of fast filter. It is named after the shape of its inlet tank. , also called a uniform particle filter material filter (the filter material uses a homogeneous filter material, that is, an average particle size filter material), a six-valve filter (there are six main valves on various pipelines), which was developed in my country at the end of the century Technology introduced from the French rn company;

Main features:
() Coarse filter material and thicker filter layer can be used to increase the Filtration cycle.
() Air and water backwash plus the ever-present lateral surface sweeping, the flushing water volume is greatly reduced.

Qiancheng brand_type filter plate filtration process: to be filtered The water flows from the main water inlet channel through the water inlet valve and the square hole, then overflows the weir and then enters the groove submerged by the water to be filtered through the side holes. It enters the filter tank through the uniform water distribution holes and the groove weir at the bottom of the tank, and is evenly distributed. The filtered water filtered by the quality filter material filter layer flows into the bottom space through the long-handled filter head, flows into the gas-water distribution pipe channel through the square hole, and flows into the clean water pool through the water sealing well, water outlet weir, and clear water channel in the pipe gallery.

Qiancheng brand_type filter plate｜Backwash process: Close the water inlet valve, but a part of the incoming water still flows into the filter from the normally open square holes on both sides, and flows from one side of the groove to the drainage channel. side, forming a surface sweep. Then open the drain valve to drain the pool surface water from the drainage channel until the filter water surface is level with the top of the groove. The backwash process often uses air flushing &rrr; air and water backwashing at the same time &rr; water flushing three times Step.
Open the air inlet valve with air blast and turn on the air supply equipment. The air enters the bottom of the filter evenly through the upper small holes of the air-water distribution channel, and is sprayed out from the long-handled filter head to scrub away the impurities on the surface of the filter material and remove them. Suspended in the water, it is washed into the drainage channel by the surface sweep water.

rb(, , );">Characteristics and design parameters of type filter plate;
Filter The speed can reach ~/, usually .~./.
Using a single layer of thickened uniform particle filter material, the particle size is generally .
For filters with filtration rates between ~/, the filter layer height should be selected between .~., and can be increased accordingly for higher filtration rates.
The bottom adopts a drainage system with a long-handled filter head bottom plate without a gravel support layer. The filter head is arranged in a mesh shape, about 1/2.
Backwashing generally adopts three processes: air flushing, simultaneous air and water backflushing and water flushing. The backwashing effect is good, which greatly saves backwash water and electricity consumption. The air flushing intensity is ~/(.)(~/. ), the clean water rinse intensity is ~/(.) (.~./.), and the raw water used for surface sweeping is generally ~/(.) (.~./.).
The particle size distribution of the entire filter material layer in the depth direction is basically uniform. During the backwashing process, the filter material layer does not expand and hydraulic grading does not occur, ensuring deep pollution interception and a high pollution-containing capacity of the filter layer.
The water depth above the filter layer is generally greater than . When backwashing, the water level drops to the top of the drainage tank, and the water depth is only .

rb(, , );">Type filter plate Simultaneous backwashing of air and water
Start the flushing water pump at the same time as air flushing, open the flushing water valve, and backwash Water also enters the air-water distribution channel. The air and water flow into the water distribution area at the bottom of the filter through small holes and square holes respectively, and evenly enter the filter through the long-handled filter head. The filter material is further rinsed, and surface scanning continues.
Stop the air flushing, and continue the independent water flushing meter sweep. Finally, all impurities in the water will be flushed into the drainage channel.
