Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that, when element is called as " setting " on another element, it can be directly can there is element placed in the middle on another element or also.When an element is considered to " be connected " with another element, it can be directly " be connected " with another element, or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in description of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Refer to Fig. 1 ~ 2, the settler overflow system of an embodiment, comprise settling tank 10, overflow launder 20, the downflow weir 30 being arranged on settling tank 10 top and the guide shell 40 be arranged in settling tank 10.
Wherein, overflow launder 20 is arranged on settling tank 10 one end near top in the form of a ring, and the bottom surface of overflow launder 20 is ramped bottom surface, and the peak of ramped bottom surface is lower than the top of settling tank 10, and the minimum point of ramped bottom surface is provided with purified liquor outlet 22.
Concrete, overflow launder 20 is arranged on settling tank 10 one end near top in irregular ring-type.This irregular ring-type extends to purified liquor outlet 22 direction draws in, makes the central shaft of above-mentioned overflow launder 20 depart from the central shaft of settling tank 10 close to purified liquor outlet 22 direction.
The bottom surface of overflow launder 20 is ramped bottom surface, and clear liquid is collected to purified liquor outlet 22 direction, and overflow launder 20 and settling tank 10 are in eccentric state simultaneously, are further convenient to the collection of clear liquid.
In the present embodiment, the below of purified liquor outlet 22 is also provided with collector groove 24, for collecting clear liquid.Anti-swirl baffle (not shown) is provided with, for preventing the generation of eddy current in collector groove 24.
In the present embodiment, downflow weir 30 is zigzag downflow weir.The teeth sizes of zigzag downflow weir can arrange corresponding specification according to the size carrying out liquid measure.
