In figure: 1, cylindrical shell; 2, intake chamber; 3, filter chamber; 4, water-supplying chamber; 5, drive chamber; 6, upper pivot flange; 7, lower support flange; 8, bearing block; 9, collect dirty hollow rotating shaft; 10, drive unit; 11, drive hole; 12, water inlet; 13, delivery port; 14, coarse strainer; 15, smart filter screen; 16, blow-off pipe; 17, blowoff valve; 18, the dirty pipe of hollow collection; 19, upper cover.

Detailed description of the invention

Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.

As shown in Figure 1, the one of the present embodiment is cleaned vertical filter automatically, comprise cylindrical shell 1, described cylindrical shell 1 comprises intake chamber 2, filter chamber 3, water-supplying chamber 4 and drive chamber 5, between described intake chamber 2 and filter chamber 3, be fixedly installed pivot flange 6, between described filter chamber 3 and drive chamber 4, be fixedly installed lower support flange 7, in the middle of described upper pivot flange 6 and lower support flange 7, be respectively arranged with bearing block 8, on described bearing block 8, be provided with the dirty hollow rotating shaft 9 of collection, the described dirty hollow rotating shaft of collection 9 lower ends are through lower support flange 7 connecting drive devices 10, described drive unit 10 both sides are provided with the drive hole 11 of opposite direction, described intake chamber 2 one sides are provided with water inlet 12, described water-supplying chamber's 4 one sides are provided with delivery port 13, between described filter chamber 3 and water-supplying chamber 4, be respectively arranged with coarse strainer 14 and smart filter screen 15, described drive chamber 5 lower ends are provided with blow-off pipe 16, on described blow-off pipe 16, be provided with blowoff valve 17, on the dirty hollow rotating shaft 9 of described collection, be provided with the dirty pipe 18 of hollow collection that is communicated with filter chamber 3.

Described cylindrical shell 1 upper end is provided with upper cover 19.

Described smart filter screen 15 is arranged on coarse strainer 14 outsides.

The drive unit 10 of the dirty hollow rotating shaft 9 of the utility model collection adopts waterpower principle to drive, pair of bearing 8 supports, its whole duty comprises 2 processes: filter and automatic pollution discharge process, under filtration duty, pending medium is flowed into by water inlet 12, the impurity of larger particles enters filter chamber 3 after by coarse strainer 14 filterings, when the impurity of fine particle is filtered by smart filter screen 15, by filtering, the cleaning medium after filtration is discharged by delivery port 13, in filter process, impurity is gradually accumulated on smart filter screen 15 inner surfaces and forms impurity screening layer, the existence of impurity screening layer can increase the drag losses of filter screen, inside and outside both sides at smart filter screen 15 just form pressure reduction, when pressure reduction reaches predetermined value, by controller opens blowoff valve 17, start automatic cleaning process, when cleaning in drive chamber 5 and drive unit 10 internal pressures decline to a great extent, the dirty pipe 18 of hollow collection and smart filter screen 15 produce a powerful suction, near the high-velocity flow dirty pipe of simultaneously hollow collection 18 entrances will be stuck in filter screen inner surface particle and sweep away, under the double action of strong suction and high-velocity flow, discharged by blow-off pipe 16 sweeping away the particle coming, the high-velocity fluid in hydro powered motor exit turns round at the dirty hollow rotating shaft 9 of drive chamber 5 interior formation jetting flow collection, dirty pipe 18 rotations of hollow collection are cleaned whole smart filter screen 15 inner surface all sites simultaneously, and discharge dirt, this duty is the process of removing contamination, in the time that the pressure drop of filter is less than preset value, controller cuts out blowoff valve 17, and the stoste volume of discharging with dirt in the process of removing contamination is no more than 1.0%, so can realize continuous continual filtration, can realize on-line filtration.
