subject: Automatic Self-cleaning Filter, One Of Many Gear For Water Treatment [print this page] The Automatic self-cleaning filter is really a water therapy equipment mainly composed from the main electromotor, filter cap, h2o distributor, and pneumatic-hydraulic backwashing devices, which functions in either from the two types: filtration and backwashing.The raw water runs through the purifying pump towards the incoming pipe of the filter, then through the central pipe to the water-distributor atop the device. The h2o is also distributed and filtered though a layer. The filter layer is composed of two layers, the higher coarse smokeless coal bars the passage of large particles, while the little types set out to the next layer of tiny quartz sand via a smokeless coal filter. Owing to the little diameter of the quartz, small particles will stay connected to the surface of the second layer. The coarse sand props up the filter method and distributes h2o, providing complete expression to the perform of every layer and the capacity of filtration. Filtered h2o runs via the filter cap to the purifying region at the bottom, and runs through the outletting pipe because the finish from the whole procedure of filtration.If pressure distinction in between the outletting and incoming pipe owing towards the huge accumulation of sludge reaches 0.05Mpa or even the time period of performance has exceeded 24 hrs, there is been an excessive amount of accumulation of impurity and a fall in the high quality of outletting h2o, therefore necessitating backwashing. During the entire process of backwashing, the incoming valve from the uncooked h2o and also the outlet valve from the filtered h2o should really be closed, and also the drainage valve of the backwashing method will need to be kept open up until no h2o comes out. Then , ultraviolet water sterilizer launch water to create the liquid level fall below the trumpet mouth when the system is expected to be under a common pressure.Open the incoming valve from the backwashing method, and also the air runs through the incoming pipe to the under part of the device. Owing towards the difference between the density of air and that of h2o, a pneumatic layer is hence placed below the under part of pore boards. Residual h2o in the device, impelled from the distinction in pneumatic stress, runs via the filter cap, which scatters water evenly, to the bottom from the filter layer upwards for automated flushing. Owing to some absence of pore or groove within the filter bar, once the pneumatic layer reaches a particular peak, air will probably be pumped via the higher pore to air-rinse the filtering substances. When the thickness of the pneumatic layer reaches an arrangement limit, the filtering substance, given the extreme influence from the air, mutually rubs against one another. Once the time span of pneumatic flushing reaches a set worth, the incoming valve should certainly be closed and the incoming valve from the backwashing method be opened to begin the flushing of filtered h2o. The flushing water might be drained from the drainage pipe. This will need to be followed by a positive-pressure flushing from the gadget through the incoming valve. The h2o ought to come from the constructive drainage pipe, till the outletting h2o is clear. This concludes the entire process of backwashing and makes the device perform usually.
