Pumped on transmission mechanism 76 and under the drive of transmission mechanism 76, for patting the water surface of filter water with to filtering
The water surface, which applies, makes the oriented energy of the downward punching press of filter water.Energy cover 78 is set on oriented energy generating mechanism 77 and is fixed on
On framework 74, the moving direction for constraining water when oriented energy generating mechanism 77 strikes waters, so that filter water edge is clapped
Play direction movement and prevent filtered water stream from being displaced outwardly along vertical flap-wise, and then reduce energy to beyond the direction that strikes waters
Direction transmission, and then reduce energy loss, improve backwash effect.
Referring to Fig. 4, present invention also offers another embodiment of energy wave generating device 73, in present embodiment
In, energy wave generating device 73 has framework 710, energy cover 720 and compressing device 730.Energy cover 720 is arranged on framework
On 710, the filter water after being filtered through filter 21 is enclosed for cover.Compressing device 730 is used to be pressed into gas into energy cover 720
The filter water enclosed with the downward inner cover of punching press energy cover 720 is so that the filter screen 22 of the downward washing and filtering device 21 of filter water.
The energy cover 720 is square, circular etc., and it has cover wall 721 and bottom wall 722.The connect cover wall of bottom wall 722
721 top, so as to prevent the gas of press-in from the top of cover wall 721 when compressing device 730 is pressed into gas into energy cover 720
End leakage, and then improve the energy of the downward punching press of gas in press-in energy cover 720.The bottom wall 722 is provided with air inlet
723, the air inlet 723 is connected with compressing device 730, thus compressing device 730 by air inlet 723 to the internal pressure of energy cover 720
Enter gas.
Compressing device 730 has gas generating device 731, gas operated device 732 and exhaust apparatus 733.Gas generation dress
It is air pump or fan to put 731.Gas operated device 732 has airway tube 734 and air guide control valve 735.One end of the airway tube 734
It is connected with gas generating device 731, its other end is connected with the air inlet 723 of energy cover 720, for by gas generating device
The gas of 731 generations is imported in energy cover 720.Air guide control valve 735 is arranged on airway tube 734, by controlling air guide to control
The opening and closing of valve 735 control the on and off of airway tube 734, therefore by controlling the unlatching of air guide control valve 735
Control gas generating device 731 is intermittent to be pressed into gas into energy cover 720 with closing.
Exhaust apparatus 733 has blast pipe 736 and gas exhausting valve 737.One end of the blast pipe 736 and airway tube
734 connections, for the gas in energy cover 720 to be discharged.Gas exhausting valve 737 is arranged on blast pipe 736, passes through the row of control
The opening and closing of gas control valve 737 control the on and off of blast pipe 736, thus open air guide control valve 735 with
Make gas generating device 731 to energy cover 720 be pressed into gas when, by closing gas exhausting valve 737 with prevent gas generation dress
Put 731 generation gases to reveal from blast pipe 736, close air guide control valve 735 so that gas generating device 731 stops to energy
In cover 720 during press-in gas, discharge the gas in energy cover 720 by opening gas exhausting valve 737, and then gas can be realized
Body generating means 731 are intermittent to be pressed into gas to energy cover 720.
Due to backwash filter tank of the invention intelligent by filtering area 20 is arranged on settling zone 10 top and with precipitation
Area 10 is connected, and clear water zone 30 is arranged to the top of filtering area 20, and back purge system 70 is arranged to the top of clear water zone 30, and
By back purge system 70 in clear water zone 30 filter water apply pressure with the filter 21 to filtering area 20 from the top down
Be rinsed, thus developing result it is good, can Gao Xinggao and without using quoting outside water purification.
Correspondingly, the present invention also provides a kind of back-flushing method in intelligent backwash filter tank, comprises the following steps：
Step 1: back purge system 70 to be moved to the relevant position of clear water zone 30；And
