Liquid level in slot 1 is more than the second liquid level 12, i.e., when the liquid level in dissolving tank 1 reaches the second liquid level 12, then stops filling the water, continue to stir
It mixes, and judges to continue whether mixing time reaches default mixing time, if it is not, then stopping filling the water, continue to stir；If so, stirring
Stopping is mixed, and executes step S4.After stopping water filling, continue stirring so that material preferably dissolves.
Specifically, continue mixing time and refer to that reaching the second liquid level 12 with the liquid level in dissolving tank 1 starts the stirring calculated
Time, default mixing time are set by mixing timer.
Example IV
As shown in Figure 4 and Figure 5, the present embodiment provides a kind of automatic dissolving methods, in the automatic dissolving that embodiment three provides
It further include step S5, step S5 is after step s4 on the basis of method.Step S5 are as follows: if solution dissolution is completed, shift molten
Liquid, and judge whether solution shifts success, if it is not, then continuing to shift solution；If so, being filled the water again into dissolving tank 1.
Specifically, judge whether solution shifts successful method and include the liquid level of dissolving tank 1 when obtaining transfer solution, and sentence
Whether the liquid level of disconnected dissolving tank 1 reaches third liquid level 13, and third liquid level 13 is the state without solution in dissolving tank 1, if it is not, then molten
Liquid transfer is failed, continues to shift solution.
Automatic dissolving method provided in this embodiment can it is automatic, efficiently, it is accurate, steadily dissolve out needed for concentration it is molten
Liquid, and solute effect is preferable, it is not easy to generate floc sedimentation.
Embodiment five
As shown in figure 5, the present embodiment also provides a kind of dissolution system that can implement above-mentioned automatic dissolving method, the dissolution
System includes dissolving tank 1, charging component 2, blender 3 and water filling component 4.The inside of dissolving tank 1 is provided as reference level

Blanking groove 21 accepts material to be dissolved, and the outlet of blanking groove 21 is connected to the entrance of conveying mechanism 22, air blower 23 and conveying
The outlet of mechanism 22, and material to be dissolved is blown into dissolving tank 1.Blender 3 protrudes into dissolving tank 1, and makes to stir
The blade of 3 bottom of device is flushed with the first liquid level 11.Component 4 is filled the water, is connected to respectively with water source and dissolving tank 1.The dissolution system
System improves dissolved efficiency so that material does not need to weigh for several times.
Specifically, the first liquid level 11 is the 30% of 1 volume of solution tank, the blade of 3 bottom of blender and the first liquid level 11
It flushes, when the liquid level in dissolving tank 1 reaches the first liquid level 11, blender 3 could be worked normally, and guarantee the liquid in dissolving tank 1
Body is constantly in rotation status, convenient for the dissolution of material.Second liquid level 12 is the 80% of 1 volume of solution tank, and solution completes dissolution
Volume, prevent blender 3 stir when solution it is excessive from dissolving tank 1, influence the accuracy of solution concentration.Third liquid level 13 is
State of the solution tank 1 without solution, facilitates whether detection solution transfer succeeds.
Specifically, conveying mechanism 22 is blanking spiral.It is equipped between blanking groove 21 and conveying mechanism 22 and big impurity is isolated
Filter screen and prevent the vibrator that blanking has some setbacks.In the process of conveying materials, it can guarantee and be full of always in blanking spiral
Material.It is opposing seal since blanking spiral only has entrance and exit, the internal capacity of blanking spiral is fixed, blanking
The revolving speed of spiral is fixed, therefore it is accurate for measuring the cutting stock weight of material according to the blanking time.
Further, water filling component 4 includes dispersion water valve 41 and water injection valve 42, and dissolving tank 1 includes feed opening 14 and water filling
Material to be dissolved is blown into feed opening 14 by mouth 15, air blower 23, and dispersion water valve 41 is connected to feed opening 14 and water source respectively, infuses
Water valve 42 is connected to water filling port 15 and water source respectively.Before solution dissolution is completed, dispersion water valve 41 is constantly in opening state；When
When feeding into dissolving tank 1, water injection valve 42 is closed.When only being filled the water into dissolving tank 1, disperses water valve 41 and water injection valve 42 is beaten
It opens, so that the liquid level in dissolving tank 1 quickly reaches the first liquid level 11.When feeding into dissolving tank 1, water injection valve 42 is closed, by
It is connected in dispersion water valve 41 with feed opening 14, so that the water that dispersion water valve 41 flows out in time breaks up out material, avoids generating wadding
Group.When into dissolving tank 1 stop charging when, water injection valve 42 open so that plus honest material dissolving tank 1 quickly reach the second liquid level
12, the time of entire course of dissolution is reduced, dissolved efficiency is improved.
It further, further include shifting pump 5, dissolving tank 1 further includes transfer outlet 16, and transfer outlet 16 connects with shifting pump 5
It is logical.After the completion of solution dissolution, shifting pump 5 is opened, and shifts solution, molten when the liquid level in dissolving tank 1 reaches third liquid level 13
Liquid shifts the dissolution work for successfully continuing next round.
Note that the above is only a better embodiment of the present invention and the applied technical principle.It will be appreciated by those skilled in the art that
The invention is not limited to the specific embodiments described herein, be able to carry out for a person skilled in the art it is various it is apparent variation,
