Other structures are same as Example 1.
When recirculated water in water circulating pump work extraction circulating water pool, driving motor drives water inlet rotation pipe rotation, makes to take
Water vertical tube turns over different location in circulating water pool, realizes the water intaking to different location in circulating water pool.In the effect for abutting spring
Under, arc blend stop is connected to always on circulating water pool inner wall, so that water intaking vertical tube is reached rectangular pool corner positions, is increased
Water intaking range is added.Floating body floats on the water surface in circulating water pool, with the height of water level, floating body drive weighted spherical ball in water on
Lower movement makes the intake of flexible pipe lower end and then float up and down together, realizes the water intaking that suspends, when rotation pipe of intaking rotates,
It is subject to centrifugal forces, weighted spherical ball is swung out, and expands water intaking range, and water intaking more evenly, is conducive to raising recirculated water and takes
The precision that sample detector detects recirculated water, to be conducive to more accurately dosing.Water intaking vertical tube rotates in circulating water pool
Agitation blades are stirred recirculated water in the process, be conducive to improve filling medicament and recirculated water it is uniform, be sufficiently mixed, from
And improve circulating water treatment effect.
Embodiment described above is the preferable scheme of the present invention, is not intended to limit the present invention in any form,
There are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
