Its working principle of vertical type backwashing filter device and the course of work provided by the invention are as follows:
Filter process:
Entire filter process is divided into three-level, and 1 level of forward filtering net in supporting filter element is put into filtering ponds first
In (river or water channel), stock solution water to be filtered is drawn into back-flushing filtering device by horizontal volute mixed-flow pump from filtering ponds
(when water to be filtered passes through forward filtering net 1, the impurity of some large sizes in filtering ponds, such as: branch, leaf, and it is other
Impurity, rubbish of some large sizes etc. will be filtered), this process is by-pass filtration；
Water after by-pass filtration first passes through banjo connector a 4,4 pipeline section of banjo connector a before entering filtering threeway 5
Product is bigger than water inlet line diameter, and the flow velocity for allowing drainage to make water when passing through threeway reduces, and passes through filtering three in water
The removal of impurities block 5-1 with gradient (135 °) is laid among pipeline when logical 5, the relatively heavy seeds for removing liquid bottom is can be used to, makes
Impurity stays in sewage pipe.Impurity blocks sewage pipe in order to prevent so that blowdown process is more smooth, design with sewage draining exit 15
Be connected to blow-off line diameter be enlarged, can more effectively exclude compared with heavy seeds, this process be secondary filtration；
For water after secondary filtration when crossing the mouth of a river 10 into net cylinder, controller controls solenoid valve C25, solenoid valve D127 and electricity
Magnet valve D228 is in the open state, and solenoid valve A 7, solenoid valve B119 and solenoid valve B220 are in close state；Water to be filtered
Enter net cylinder by solenoid valve D127 and solenoid valve D228 to cross in the mouth of a river 10, the inner conical surface that net cylinder crosses the mouth of a river 10 be designed to 45 degree it is oblique
Face not only can carry out reduction of speed to the water for entering the mouth of a river when water inlet filtering, so that it is generated vortex phenomenon, a little impurity be stayed in
Bottom, and the vortex phenomenon that can equally generate when backwash, the water for being conducive to backwash take away the impurity of deposition, inclined-plane knot
So that backwash will not leave behind dead angle, removal of impurities is more thorough for the design of structure.Water to be filtered is after net cylinder crosses the mouth of a river 10, due to pressure
Effect passes sequentially through bottom screen, filtrate bed course, the coarse filtration bed of material, the fine filtering bed of material " from the bottom up ", and above procedure is three-stage filtration,
Water after final filtration is discharged to outside back-flushing filtering device by outlet three way, solenoid valve C 25 and clear liquid outlet pipe 24.It crosses
After filtering a period of time, controller periodically controls solenoid valve A 7, solenoid valve B119 and solenoid valve according to preset blowing period
B220 is opened, being deposited in the horizontal straight tube where banjo connector b 7 during filtering and net cylinder crosses the heavier of 10 bottom of the mouth of a river
Impurity is discharged in time, and the lasting opening time of valve is preset by controller, and above step is filter process.
Backwash process:
After filtration operation carries out a period of time, bottom screen, filtrate bed course, the coarse filtration bed of material and fine filtering bed of material bottom are gradually
Foul, the impurity in water are accumulated, forms impurity screening layer, therefore the pressure intracavitary in the left and right two that net cylinder crosses the mouth of a river 10 can rise
Height, be separately positioned on two chambers of left and right pressure sensor detect where intracavitary pressure when reaching preset value, will open automatically
The backwash process of the chamber is opened, such as: left cavity pressure first reaches pressure preset, and controller controls solenoid valve B119, electromagnetism
Valve C 25 and solenoid valve D228 are in the open state, and solenoid valve A7, solenoid valve B220 and solenoid valve D127 are in close state；This
When filtering net cylinder in right side filtration operation continue, for filtered water when passing through outlet three way, a part of water flows through electromagnetism
Valve C 25 and clear liquid outlet pipe 24 are discharged to outside back-flushing filtering device, and a part flows into filtering net cylinder left side top and recoils
Wash operation；When filtered water is when entering filtering net cylinder left chamber by outlet three way, due to outlet three way and net cylinder top cover 26
At an angle, filtered water can produce vortex phenomenon when entering filtering net cylinder left chamber, and then can make the water of backwash
Cover the position that each needs of filtering net cylinder rinse.Filtered water is out of filtering net cylinder " from top to bottom " to fine filtering material
Layer, the coarse filtration bed of material, filtrate bed course and bottom screen are backwashed, and the impurity and foul on every aspect pass through net cylinder by water flow
The left chamber and corresponding left side solenoid valve B119 discharge at the mouth of a river 10 are crossed, and then completes the backsurging operation of filtering net cylinder left chamber.Together
Reason only need to control solenoid valve B220, solenoid valve C 25 and solenoid valve by controller to the backsurging operation of filtering net cylinder right chamber
D126 is in the open state, and solenoid valve A7, solenoid valve B119 and solenoid valve D227 are in close state.
Special state:
When in each filtering net cylinder level impurity and foul accumulation it is excessive, device filter and backwash two states it is same
When Shi Jinhang, when being not thorough to filtering net cylinder internal cleaning, net cylinder crosses 10 internal pressure sensor of the mouth of a river and monitors that pressure continues
It increases, the i.e. controllable solenoid valve C 25 of controller is closed, so that the filtered water in side is all backwashed the injection other side
Powerful backsurging operation mode is opened in operation, be conducive to in filtering net cylinder level impurity and foul carry out it is quickly thoroughly clear
It removes.After the completion of backsurging operation, solenoid valve C25 is opened, and back-flushing filtering device carries out the filtering of normal mode, backsurging operation
Mode.
