Embodiment
Referring to figs. 1 through Fig. 3, the utility model sand prevention deep-well pump embodiment is described further.
A kind of sand prevention deep-well pump, comprise the portion of drawing water 1, filter house 2, motor section 3, described motor section 3 is fixedly connected on filter house 2 two ends respectively with portion 1 of drawing water, described filter house 2 excircle side is provided with sand prevention filtrating equipment 5, described sand prevention filtrating equipment 5 comprises columnar filtration body 51, described filtration body 51 excircle side circumference array has several Filter columns 52, described Filter column 52 one end is all integrally arranged on filtration body 51 excircle side, described Filter column 52 cross section is rhombus, described rhombus minimum angle diagonal and filtration body 51 axes normal, described Filter column 52 inside is provided with circulation cavity 53, described circulation cavity 53 runs through filtration body 51, described Filter column 52 excircle side is provided with several filtering hole 54, described filtering hole 54 communicates with circulation cavity 53, described filtration body 51 is rotatably connected on filter house 2 excircle side by bearing, described filtration body 51 is highly not less than filter house 2 height, described filtration body 51 is fixedly connected with connecting rod 6, described connecting rod 6 is connected with motor shaft 4 near filtration body 51 the other end, described Filter column 52 minimum angles is 15 degree, when deep-well pump works, drivening rod 6 rotates, sand prevention filtrating equipment 5 is rotated in filter house 2 excircle side, and deep-well pump has good self-absorption function, make extraneous water by filtering hole 54, circulation cavity 53 arrives filter house 2, draw water, when water is by filtering hole 54, the grains of sand filter to external world, improve filtering effect, and rotating because sand prevention filtrating equipment 5 is whole, rotated together by the water-band grains of sand that sand prevention filtrating equipment 5 stirs, because grains of sand quality causes more greatly centrifugal force also large, the grains of sand are outwards thrown away, substantially increase the clean of the water of water suction place, extraneous water is subject to the suction axially identical with filtering hole 54, and sand prevention filtrating equipment 5 when rotating water to the reaction force of sand prevention filtrating equipment 5, when being bonded at filtering hole 54 after sand filtration by the rotation of sand prevention filtrating equipment 5, the grains of sand wash away along Filter column 52 side flow of rhombus by the extraneous water drawn in hole 54 of not being filtered, effectively prevent the grains of sand from sticking in filtering hole 54, sand prevention filtrating equipment 5 is made to have automatic cleaning action, substantially increase filtering effect and the rate of filtration, make deep-well pump can adapt to the larger water body of sand content, and Filter column 52 minimum angles is 15 degree effectively reduces the resistance of water to Filter column 52, decrease the burden of motor section 3, improve the working life of deep-well pump.
