Embodiment 1

[0015] see attached Figure 1-Figure 3 , this embodiment consists of a power wheel 1, a power bin 2, a water conduit 5, a draft tube 6, an impeller 3 coaxial with the power wheel 1, a pump body 4 that accommodates the impeller 3, a water inlet pipe 7 connected to the pump body 4, and an outlet The water pipe 8 is constituted. The power wheel 1 is composed of a turntable 1.1 and a water bucket 1.2, the power bin 2 is composed of a cavity surrounding the power wheel 1, and the inner wall of the power bin 2 is close to the annular space swept by the turntable 1.1 and the water bucket 1.2, The diameter of the flow channel of the power chamber 2 in this embodiment is 10mm, the diameter of the water bucket is 9mm, and the design gap is 0.5mm. The small gap design can reduce the reactive flow of water, make full use of the kinetic energy of the tap water, and keep the water flow in the flow channel. The pressure and flow rate increase the bearing capacity. The water conduit 5 is com...

Embodiment 2

[0017] see Figure 4 , compared with the embodiment 1, the main difference is: the runner 1 uses the non-directional blade 1.2 instead of the directional water bucket 1.2 in the embodiment 1, so the water conduit 4 and the draft tube 5 can be mutually replacement, making the installation more convenient. The rest of the unmentioned parts are the same as those in Example 1.

Abstract

The invention discloses a device for pumping recycled water by utilizing the kinetic energy of tap water. The device comprises a pump body, an impeller, a power wheel and a power bin, wherein the power wheel and the power bin are coaxially arranged with the impeller; the power wheel comprises a wheel disc and a water skip / blade. The device is characterized by further comprising an aqueduct and a draft tube which are connected with the power bin; the inner wall of the power bin is close to the circular space formed by rotation of the wheel disc and the water skip / blade; the aqueduct comprises a gradually-reducing conical tube; the draft tube mainly comprises a gradually-enlarging conical tube; the diameter of the impeller is larger than that of the power wheel; the axes of the aqueduct and the draft tube coincide, and are tangent to part of the center line of a circular cavity; the circular cavity is formed by surrounding the water skip / blade with the power bin; the large mouths and the small mouths of the aqueduct and the draft tube have the same calibers respectively; the caliber of each small mouth is equal to the inner diameter of the circular cavity. Compared with the prior art, the device is simpler in structure, smaller in size, lower in cost, and easy to mount and popularize, and has the benefits that the tail water flow rate is maintained, and the utilization rate of water resources is improved.

Description

technical field [0001] The invention relates to a water-saving device, in particular to a water-saving device that utilizes the kinetic energy of tap water to extract and recycle water. Background technique [0002] Chinese Patent Publication No. CN 101070853A provides a water-saving device that utilizes the kinetic energy of tap water itself to drive a water pump. The water column coming out of the "inner cone hole joint" impacts the rotation of the power wheel, which drives the coaxial impeller to rotate, and raises the waste water to the At a certain height, it can be stored for secondary use." This scheme is a recombination of an impulse hydro-generator and a simple submersible sewage pump. The advantage is that it does not need to consume electricity. The water outlet, and the shower head are much higher than the tap water outlet of the household tap water pipe and other purposes, so the bath water cannot be used, and because the pump wheel needs to be lower than the le...
