The staff can intuitively see the accumulation condition of impurities on the surfaces of the upper filter material layer 11, the middle filter material layer 12 and the lower filter material layer 13 on the display screen 7, so that whether a certain filter material layer needs to be replaced can be timely confirmed, and error judgment on whether the filter material layer needs to be replaced due to unclear observation is avoided (if the filter material layer needs to be replaced, the workload is increased, the filter material cost is increased, and if the filter material layer needs to be replaced, the filter effect is reduced). Of course, each underwater camera with the lamp does not need to be in the on state continuously, and a worker can periodically turn on each underwater camera with the lamp through the electric control device 6 to periodically observe each filter layer.
The side wall of the tank body 1 is provided with an upper filling opening, a middle filling opening and a lower filling opening at intervals from top to bottom, wherein the upper filling opening corresponds to the upper filter material layer 11, the middle filling opening corresponds to the middle filter material layer 12, and the lower filling opening corresponds to the lower filter material layer 13;

During normal filtration, the blowdown solenoid valve 10 is closed, the water inlet solenoid valve 8 and the water outlet solenoid valve 9 are both opened, the water outlet solenoid valve 9 is normally in a normally open state, and the system is closed during maintenance. Raw water to be filtered enters the tank body 1 from top to bottom through the water inlet pipe 2 and sequentially passes through the upper filter material layer 11, the middle filter material layer 12 and the lower filter material layer 13. The water is physically coarse filtered when passing through the upper filter material layer 11 with the largest particle, and simultaneously, the activated carbon particles have adsorption effect on organic matters and partial inorganic matters in the water, and adsorb harmful matters in the water. The water is filtered when passing through quartz sand particles with the diameter of 0.8-1.2 mm, and suspended particles, colloid substances, microorganisms and the like in the water can be trapped by the quartz sand to form a filtering membrane, so that the filtering coarseness is improved. The water is physically fine filtered when passing through the lower filtering material layer with the smallest particles, and the ferromagnetic substances in the water are magnetically filtered when passing through magnetite particles. The filtered clean water is supplied to a water unit through a water outlet 4 and a downstream water pipe.
As the filtration proceeds, the impurities trapped by the upper filter material layer 11, the middle filter material layer 12 and the lower filter material layer 13 are more and more, the filtration resistance is more and more, the pressure difference between the water inlet pipe 2 and the water outlet 4 is also more and more, when the pressure difference exceeds a preset value, the pressure difference sensor 5 sends a signal to the electric control device 6, and the electric control device 6 closes the water inlet electromagnetic valve 8; the water pressure in the pipeline system at the downstream of the tank body 1 is higher than the atmospheric pressure, so that the purified water in the pipeline system at the downstream of the tank body 1 flows back at the moment, reversely passes through the plurality of filter material layers from bottom to top and is discharged through the sewage outlet, and impurities absorbed in the filter material layers are taken away to realize back flushing. The back flushing can be automatically stopped after the back flushing reaches the preset time and converted into normal filtration (the electric control device is connected with or internally provided with a timer which can realize the timing function), and the back flushing time can also be manually controlled by a worker. After back flushing, the electric control device 6 opens the water inlet electromagnetic valve 8 to resume the normal filtering process.
The water pump in the system is positioned at the upstream of the utility model; if the strength of back flushing needs to be improved, a bypass pipe can be arranged, and the bypass pipe is communicated with a water pump outlet and a water consumption unit inlet; the bypass solenoid valve is arranged on the bypass pipe. During back flushing, the bypass electromagnetic valve is opened while the water inlet electromagnetic valve 8 is closed, so that purified water in a downstream water pipe between the tank body 1 and the water unit inlet flows back to the sewage discharge pipe 3 under higher pressure, and the back flushing strength (simultaneously utilized or filtered purified water in the downstream water pipe) is improved. After back flushing, the bypass solenoid valve is also closed at the same time as the inlet solenoid valve 8 is opened.
In the prior art, workers can only observe the side parts of each filter material layer through the filling openings, and cannot observe the surfaces of the filter material layers concentrated in impurities. By adopting the utility model, a worker can periodically start the underwater camera with the lamp through the electric control device 6, thereby observing the surface condition of each filter material layer and more accurately determining whether the filter material needs to be replaced. When the filter material is replaced, the corresponding filler cover is opened to clean out
