Description
Technical field
The utility model is related to a kind of mixing arrangement, more particularly to the mixing arrangement of the liquid of two kinds of different densities.
Background technology
With the silicon material cleaning of photovoltaic industry and cell piece etching, in wet method trimming technology, it is necessary to use HNO3, HCL,
HF, KOH etc. highly corrosive chemicals should ensure chemicals according to process requirements periodically, quantitatively in process of production
Supply, and must assure that the life security of operating personnel.The supply of chemicals must just realize automation, unattended confession
It should.Risk factor is preferably minimized, while the hysteresis quality of personnel's operation is solved with accurate electric signal.But this equipment
Cost is higher, needs to spend the expense of great number.
Invention content
Technical problem to be solved in the utility model is：How to provide a kind of simple in structure, mixed effect is accurately changed
Product mixing apparatus.
Technical solution is used by the utility model：Two kinds of chemicals mixing automatic supply devices, in sealing container（1）
Bottom have liquid outlet（3）With the first valve（2）, in sealing container（1）Top have the first inlet tube（8）With the second inlet tube
（6）, in sealing container（1）Inside have the first float（10）With the second float（4）, the first float（10）Head extends into
One inlet tube（8）Ball determine liquid mark, the second float（4）Head extends into the second inlet tube（6）Ball determine liquid mark, first
Inlet tube（8）It is flare openings for rigid pipe and lower mouth, the second inlet tube（6）It is opened for rigid pipe and lower mouth to be horn-like
Mouthful.
As a kind of preferred embodiment：First inlet tube（8）On have the second valve（9）, the second inlet tube（6）On have third valve
Door（5）.
As a kind of preferred embodiment：Sealing container（1）On have gas outlet（7）With the 4th valve（11）.
As a kind of preferred embodiment：First float（10）With the second float（4）Tail portion be all spherical and be all placed on one
A tubular rail tube（12）In.
The beneficial effects of the utility model are：The utility model is cheap, and good mixing effect disclosure satisfy that photovoltaic industry
Needs.

Specific embodiment
As shown in Figure 1, the utility model is used to implement the mixing of the liquid to two kinds of different densities, the present embodiment is as realized
Mixing to HNO3 and HCL, the first inlet tube Connection Density small fluidic interface is connection HCL sources in the present embodiment, second into
Liquid pipe Connection Density big fluidic interface is connection HNO3 sources in the present embodiment, different to the mixing requirement selection of various concentration
First float of size and the sphere of the second float tail portion make the first float and the second float when reaching aimed concn be in flat
Weighing apparatus state, it is close when mixing liquid density in closed container is less than normal concentration when HCL contents are exceeded in closed container
Degree, at this moment the first float and the second float can float, and the feed liquor of the first inlet tube becomes smaller（HCL feed liquors become smaller）, the second inlet tube
Feed liquor can become larger（HNO3 feed liquors become larger）, until reach normal concentration, and when HNO3 contents are exceeded in closed container, closed container
In mixing liquid density be more than normal concentration when density, at this moment the first float and the second float can decline, the first inlet tube
Feed liquor become larger（HCL feed liquors become larger）, the second inlet tube feed liquor can become smaller（HNO3 feed liquors become smaller）, until reaching normal concentration.
