State the both ends of strainer installation cavity；The strainer installation cavity is equipped with cavity inlet opening, the strainer close to one end of the water inlet
The other end of installation cavity is connected with the housing seal, and impeller is equipped between the cavity inlet opening and the water inlet, described
Impeller is fixed on one end of the hollow shaft；The other end of the hollow shaft is backwash outlet；If the hollow shaft is equipped with
Dry attraction channel, the end of the attraction channel is suction nozzle, and the suction nozzle is located at the inside of the cylindrical filter screen.
The both ends of the strainer installation cavity are made of upper stop piece and lower stop piece respectively, the cavity inlet opening be located at it is described under
On baffle, the cavity inlet opening is connected to the inside of the cylindrical filter screen.
The linear suction nozzle of suction nozzle.
It is connected between the hollow shaft and the impeller for interference fit.
The hollow shaft it is closed at one end, the backwash outlet of the hollow shaft is connected with deslagging pump.
The quantity of the attraction channel is 4-12 and is uniformly arranged in the hollow shaft.
The impeller is unshrouded impeller, and the hub head end of impeller is in bullet-shaped structure, described in the impeller size covering
Water inlet.
The beneficial effects of the present invention are: directly driving hollow shaft and suction nozzle using waterpower by the impeller and hollow shaft
Movement realizes filtering and discharge impurity, has fully phased out the driving motor of back purge system, gear transmission mechanism in the prior art
And the control mechanisms such as limit switch, filter height dimension is reduced, moving component is reduced；Present invention manufacture, installation and Maintenance Difficulty
