Detailed ways

Referring to accompanying drawing 1, a kind of high-efficiency fiber bundle filter of the present utility model comprises filter tank 1, fiber bundle filler 2, movable perforated plate 3, fixed perforated plate 4, water inlet pipe 5, U-shaped water pipe 6, water outlet pipe 7, recoil Water inlet pipe 8, three-way switch 9, emptying pipe 10, air intake pipe 11, exhaust pipe 12, valve switch 13, backwash water outlet pipe 14. The filter tank 1 is composed of an upper head 15, a tank body 16, and a lower head 17. A U-shaped water pipe 6 is installed on the top of the head 15 on the filter tank 1, and the other end of the U-shaped water pipe 6 is respectively connected to the outlet pipe through a three-way switch 9. 7 is connected with the recoil water inlet pipe 8, and the upper head 15 is equipped with an intake pipe 11 and an exhaust pipe 12 at an appropriate position, and a valve switch 13 is arranged on the air intake pipe 11 and the exhaust pipe 12, and the lower end of the filter tank 1 17. An emptying pipe 10 is installed at the bottom, and a valve switch 13 is arranged on the emptying pipe 10. The tank body 16 of the filter tank 1 is installed with a water inlet pipe 5 and a recoil water outlet pipe 14 near the lower head 17. The water inlet pipe 5 and There are valve switches 13 on the recoil water outlet pipe 14 . A movable porous plate 3 and a fixed porous plate 4 are installed in the tank body 16 of the filter tank 1 , and the fiber bundle filler 2 is filled between the movable porous plate 3 and the fixed porous plate 4 .

When in use, first close the valve switch 13 of the emptying pipe 10, the intake pipe 11, and the backwash water outlet pipe 14, and simultaneously open the valve switch 13 on the water inlet pipe 5 and the exhaust pipe 12, and adjust the three-way switch 9 to the outlet. The water pipe 7 is opened, the recoil water inlet pipe 8 is closed, and then the industrial wastewater containing impurities is continuously filtered into the tank 1 from the water inlet pipe 5, and the purpose of opening the valve switch 13 on the exhaust pipe 12 is to prevent the An air plug is generated in the filter tank 1 to prevent the movement of the water body. When the water body passes through the movable porous plate 3, the water body passes through the area where the fiber bundle filler 2 is located and is filtered by the filler 2. At the same time, the movable porous plate 3 is pushed upward by the water body and gradually approaches the fixed porous plate. Plate 4, the fiber bundle filler 2 between the movable porous plate 3 and the fixed porous plate 4 is gradually compressed from the elongated state, the pores of the filter material along the water direction gradually become smaller, the fiber density increases, and the water continues to move upward after being filtered. Part of the impurities filtered by the fiber bundle filler 2 falls into the lower head 17, and part of it is adsorbed on the fiber bundle filler 2. The filtered water is discharged along the U-shaped water pipe 6 through the three-way switch 9 and the outlet pipe 7. Out of the filter tank 1 for recycling. And when the impurity in the lower head 17 accumulates to a certain degree, stop water intake, open the valve switch 13 on the emptying pipe 10, impurity is evacuated and dealt with separately.

After using for a period of time, impurities may remain on the fiber bundle filler 2, which affects the separation effect. At this time, start the backwash water system to flush the fiber bundle filler 2, etc., that is, first close the water inlet pipe 5 and the drain pipe 10. Valve switch 13, adjust the three-way switch 9 until the water outlet pipe 7 is closed, the recoil water inlet pipe 8 is opened, and at the same time open the valve switch 13 on the recoil water outlet pipe 14, and the clean recoil water will flow from the recoil water inlet pipe 8 Enter the filter tank 1 through the three-way switch 9 and the U-shaped water pipe 6, the backwash water first washes the fixed porous plate 4, then sprays on the fiber bundle packing 2 to wash the fiber bundle packing 2, and finally washes the movable porous plate 3 During the entire flushing process, the fiber bundle packing 2 gradually stretches from the original compressed state, and the movable porous plate 3 gradually moves down until it reaches the initial state before filtration. During the flushing process, as required, the valve switch 13 on the intake pipe 11 can also be opened, and the air flow is used to cause the fiber bundle packing 2 to vibrate, so that the impurities adsorbed on its surface are washed more thoroughly. The sewage after flushing is discharged from the backwash water outlet pipe 14. After flushing, the valve switch 13 on the emptying pipe 10 is opened, and the sewage remaining in the lower head 17 is emptied.
