Embodiment
The utility model is described in detail below with reference to accompanying drawing, however itself and be not used to limit the utility model
Practical range.
As illustrated in fig. 1 and 2, a kind of more filter core automatic backwashing filters, including housing 1, multiple filter cores 2, pressure difference switch 3,
Blowoff valve 4, cleaning machine and controller 5, the bottom of housing 1 are provided with scale removing mouth 6, and the upper end of housing 1 is provided with two hangers
7, controller 5 is PLC, and PLC is connected with computer, realizes remote control, and multiple circumference uniform distributions of filter core 2 exist
In housing 1, pressure difference switch 3 and controller 5 are arranged at the outside of housing 1, and housing 1 is respectively stretched at the both ends of pressure difference switch 3
Water inlet 8 and delivery port 9 in, be respectively arranged with adpting flange on the water inlet 8 and delivery port 9 of housing 1；Cleaning machine includes
Power transmission shaft 10, the closing disk 11 being arranged on power transmission shaft 10 and sucker 12, the upper end of power transmission shaft 10 pass through gearbox 13 and motor 14
It is connected, closing disk 11 and sucker 12 are fixed on the inside of housing 1 by power transmission shaft 10, and distance is more than between closing disk 11 and sucker 12
The height of filter core 2, the lower end of sucker 12 are connected by pipeline with blowoff valve 4；The upper end of power transmission shaft 10 passes through upper steering spindle 15
It is connected on housing 1, the lower end of sucker 12 is connected to the bottom of housing 1 by lower steering spindle 16, and being provided with position in housing 1 opens
