Compare with present technological scheme, under the utility model liquid, vertical pump filter screen Cleaning device for pipeline, except retaining original effect of filtering foreign material, has increased the clearing function that filter screen stops up.Under the utility model liquid, vertical pump filter screen Cleaning device for pipeline vertical pump suction port place under liquid is provided with a slewing gear, slewing gear is comprised of impeller and rotatingshaft, by pressure gas source, impact impeller and produce rotation torque, the rotation of driving rotatingshaft, rotatingshaft carrys out the obstruction on scraping filter screen outer wall by being arranged on the scraper of filter screen lower end, meanwhile, the air pressure that enters vertical pump entrance under liquid purges from inside to outside to filter screen obstruction, thereby plays the effect that filter screen stops up of eliminating.
Accompanying drawing explanation
Fig. 1 is the structural representation of vertical pump filter screen Cleaning device for pipeline under the utility model liquid;
Fig. 2 is the plan view of crossing water enclosure interior and blade wheel structure in Fig. 1;
Fig. 3 is the enlarged view of the upper support seat in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 3, cross water piece housing 1 upper-end surface and offer 4 fixed bolt holes, and align with Pump Suction Nozzle bolt hole position; Upper support seat 4 is provided with circular groove, and supporting base 4 central through bore diameters are larger than rotatingshaft diameter, and the diameter of groove is 2 times of rotatingshaft 5 diameters.As shown in Figure 2, by support 3, upper support seat 4 and mistake water piece housing 1 bottom inside are horizontally welded together.
As depicted in figs. 1 and 2, in impeller 9, offer keyway.Impeller 9 is Spielpassung with rotatingshaft.
Scraper 23 horizontal symmetrical are welded on axle sleeve 12 both sides, and in axle sleeve 12, offering keyway and rotatingshaft is Spielpassung.Scraper 23 is Spielpassung with filter screen 2.
As shown in Figure 1, the material of rotatingshaft 5 is polytetrafluoroethylmaterial material, and the interior positioning spline that arranges of impeller 9, at impeller 9 and scraper 23 and the screw thread of rotatingshaft 5 arranged outside for locking nut.In rotatingshaft 5 and upper and lower supporting base, keyway is offered in the cooperation place of supporting positive cover.
