Description
Technical field
The utility model relates to a kind of device of accurate control liquid groundwater increment.
Background technology
Beverage is adding man-hour, for the strict percentum of controlling each composition in beverage, conventionally need to add with quantitatively filling device the operation of liquid.The quantitative perfusion of liquid adopts volumetric method (being discharge method) or weight to realize the accurate perfusion of liquid conventionally, volumetric method is according to the volume of liquid, to determine the groundwater increment of liquid, weighting method is to utilize weighting apparatus to weigh liquid to realize accurately perfusion, due to weighting method having relatively high expectations to equipment, in actual production process, most device for casting is all to adopt volumetric method.
Existing device for casting is when perfusion fluid raw material; because common meeting in pipeline is with part tail washings; after perfusion completes; these tail washings can not persist conventionally in pipeline, and its pipeline of can postponing flows into be treated in the vessel of liquid feeding, therefore; the actual addition of liquid tends to be greater than the liquid addition of calculating; although can adjust by the residual volume of tail washings in estimation pipeline,, it is still difficult to realize the accurate control of liquid groundwater increment.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of device of accurate control liquid groundwater increment, and tail washings remaining in its pipeline can not flow out, and can control accurately the addition of liquid.
For achieving the above object, the utility model adopts following technical scheme:
Precisely control the device of liquid groundwater increment, comprise,
Fluid reservoir, its bottom be connected with one with the drain pipe of its inner chamber conducting;
Infusion pump, this transfusion delivery side of pump is communicated with the bottom of fluid reservoir by a liquid pushing tube, and infusion pump is for being pumped into fluid reservoir by liquid;
Level control valve (LCV), is installed on liquid pushing tube;
Quantitative perfusion valve, is arranged on one and is connected on the drain pipe of fluid reservoir bottom;
Level sensor, is arranged in fluid reservoir, for surveying the electrolyte level in fluid reservoir;
Controller, the altitude signal of the inner liquid level of the fluid reservoir sending for the level sensor according to receiving is controlled the unlatching of level control valve (LCV) and quantitative perfusion valve or closes.
The intracavity diameter of fluid reservoir is less than or equal to 40cm.
The top ends of fluid reservoir is provided with an end cap, and level sensor is positioned at fluid reservoir inside and its top ends is fixed on end cap.
The beneficial effects of the utility model are:
Than prior art, the utility model is controlled level control valve (LCV) and quantitative perfusion valve by level sensor, after the inner liquid level of the addition of liquid and fluid reservoir reduces, the liquid volume of output is suitable, and tail washings remaining in pipeline can not be added into, thereby can control accurately the addition of liquid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1, fluid reservoir; 2, level sensor; 3, level control valve (LCV); 4, infusion pump; 5, liquid pushing tube; 6, drain pipe; 7, quantitative perfusion valve.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, device for a kind of accurate control liquid groundwater increment of the utility model, it comprises fluid reservoir 1, infusion pump 4, level control valve (LCV) 3, level sensor 2 and controller, the upper opening of fluid reservoir 1, opening part capping at an upper portion thereof has an end cap, infusion pump 4 is communicated with the inner chamber of fluid reservoir 1 by a liquid pushing tube 5, concrete is, one end of liquid pushing tube 5 is communicated with the mouth of infusion pump 4, the other end extends through the diapire that an elbow piece is connected in fluid reservoir 1 downwards, and infusion pump 4 is for being pumped into fluid reservoir 1 by liquid to be poured into.Level control valve (LCV) 3 is arranged on liquid pushing tube 5.The bottom of fluid reservoir 1 is also provided with one by the drain pipe 6 of liquid output, and a certain amount of pouring valve 7 is also installed on this drain pipe 6.
Level sensor 2 is arranged at the inner chamber of fluid reservoir 1, its top ends is fixed on the end cap of fluid reservoir 1 top ends, this level sensor 2 is for surveying the electrolyte level of fluid reservoir 1 inside, and the electrolyte level value that this is detected sends to controller, the signal that controller sends according to the level sensor 2 receiving, controls the unlatching of level control valve (LCV) 3 and quantitative perfusion valve 7 or closes.
When perfusion fluid, level control valve (LCV) 3 is opened, quantitative perfusion valve 7 cuts out, open infusion pump 4, to fluid reservoir 1 inside, pump into liquid to be added, when the electrolyte level in fluid reservoir 1 reaches height h1, level sensor 2 detects electrolyte level signal, and signal is sent to controller, controller controls level control valve (LCV) 3 and cuts out, quantitative perfusion valve 7 is opened, start to add liquid, when the electrolyte level in fluid reservoir 1 reaches h2, level sensor 2 detects electrolyte level signal, and signal is sent to controller, controller controls quantitative perfusion valve 7 and cuts out, complete the perfusion of liquid.
In order further to realize the accurate perfusion of liquid, the intracavity diameter of fluid reservoir 1 is less than or equal to 40cm, and the inside diameter of fluid reservoir 1 is less, and the variation of its liquid level is comparatively obvious.
Because liquid pushing tube 5 is connected in the bottom of fluid reservoir 1, therefore, when to fluid reservoir 1 inner filling liquid, the bubble that liquid produces can not impact liquid level.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
