Description

A kind of intelligent liquid-transfering device

Technical field

The utility model belongs to field of chemical equipment, and in particular to a kind of small intelligent liquid relief dress of Chemical Engineering Laboratory Put.

Background technology

The instrument for measuring liquid commonly used in existing chemical experiment room is generally all pipette；And pipette is for standard Really pipette the measuring device of the solution of certain volume.Pipette is that one kind measures formula instrument, is only used for measuring the body that it releases solution Product, it is a centre or the slender glass tube for having an enlargement.Its lower end is sharp mouth shape, and a mark is carved with the neck of upper end Line, it is the mark of pipetted exact volume.

Pipette generally includes two steps when measuring liquid：First, draw solution：Solution to be inhaled is shaken up, will wait to inhale molten Liquid falls sub-fraction in a clean and dry small beaker, is inhaled the moisture inside and outside the pipette tip cleaned with filter paper It is dry, and draw solution in small beaker is inserted, when being drawn to the 1/3 of pipette capacity, the mouth of pipe is pinned with right hand forefinger immediately, is taken Go out, it is horizontal to hold and rotate pipette, solution is flowed through full inside pipe wall, solution is discharged into waste liquid cup at the sharp-crested of lower end；So behaviour Make, can draw solution after rinse 3-4 times；Treated being inserted with the pipette for treating imbibition rinse under imbibition face at 1~2cm Aforesaid operations method draw solution is pressed with rubber pipette bulb（Notice that pipette insertion solution can not be too deep, and want down to insert when inhaling, Remain this depth）；When intraluminal fluid face rises to more than graticule about at 1~2cm, the mouth of pipe is blocked with right hand forefinger rapidly （If now below incidence to normal line, it should draw again）, pipette is proposed to treat imbibition face, and treat tip end in contact Imbibition container inner wall lifts in a moment, and pipette or a small amount of solution of pipette lower end adhesion are dried with filter paper（In mobile liquid relief When pipe or pipette, pipette or pipette should be kept vertical, it is impossible to tilt）.2nd, constantly regulate liquid level：Left hand separately takes one Clean small beaker, pipette tip is abutted into small beaker inwall, small beaker keeps tilting, and pipette is kept vertical, graduation mark With sight keep level（Left hand can not contact pipette）.Forefinger is unclamped slightly（Pipette or pipette can be rotated slightly）, make Solution slowly flows out from lower mouth in pipe, during the near graduation mark of liquid level, by tight right hand forefinger, pauses a moment, then by upper method by solution Meniscus bottom line put untill tangent with graticule upper limb, immediately with forefinger compress the mouth of pipe.Beaker inwall will be abutted at sharp-crested, to The movement of beaker mouth is a little, removes the drop at sharp-crested.Pipette or pipette are carefully moved in the container for accepting solution.

In summary, current pipette in operation complex steps, taking liquid, time-consuming, takes liquid measure not influence precisely The data of experiment, the problem such as wasted time and energy, take liquid efficiency low, and very big inconvenience is brought to experimental work.

Utility model content

The purpose of this utility model be to provide it is a kind of have it is simple to operate, time saving and energy saving, take the fast and accurate intelligence of liquid Liquid-transfering device can be changed.

The utility model discloses a kind of intelligent liquid-transfering device, including with graduated glass liquid pipe, ultrasonic water level Sensor, anti-suck bubbler, vavuum pump and control module；Described ultrasonic water level sensor is arranged in glass liquid pipe Any position in portion above maximum scale value；Pass through connecting tube and anti-suck bubbling at the upper orifice of described glass liquid pipe One gas port of device is connected, and another gas port of anti-suck bubbler is connected by connecting tube with vavuum pump；The vavuum pump and control Module is connected, and ultrasonic water level sensor is connected by signal processor with control module.

Further improve, described control module include be used for control vacuum pump switch controller and with controller electricity The Data Analysis Services module of gas connection.

Further improve, the Data Analysis Services module is connected by signal processor with ultrasonic water level sensor.

Further improve, described connecting tube is rubber tube.

Operation principle of the present utility model：First pass through computer or cell phone application setting to be taken the amount of liquid, then pass through Data Analysis Services module transfer opens water work to controller, starts imbibition；Data Analysis Services module passes through letter simultaneously Number processor delivers a signal to be measured water level in real time, and level sensor also sends a signal to Data Analysis Services mould in real time Block, when the water level signal of actual measurement is identical with setting water level signal, Data Analysis Services module transfer is closed to controller and fed water Equipment, so as to accurately complete to take liquid.

The beneficial effects of the utility model are：

Compared with prior art, the utility model employs intelligent structure so that the device takes liquid during liquid is taken Efficiency than originally provides tens times, or even hundred times, not only solves the inaccuracy due to taking liquid inaccuracy to cause experimental data The problem of so as to need the complicated processes of many experiments checking, also solve because many experiments are verified so as to waste chemical raw material The problem of, and effectively time and manpower is saved；The utility model have operate it is intelligent, simple and convenient, time saving and energy saving, Cost-effective, efficiency high, the advantages that taking liquid not only fast but also accurate.
