Description

A kind of chemical laboratory vapour-pressure type acid cylinder

Technical field

This utility model is related to the instrument field of chemical laboratory cleaning ware, specially a kind of Pneumatic type lifting liquid level Sour cylinder.

Background technology

Sour cylinder is mainly used in the glass drying ovens such as chemical laboratory soaking and washing beaker, test tube, conical flask, pipet, sometimes Also it is used for plastics sampling bottle carrying out cleaning and sterilizing in order to avoid antibacterial produces the acid in destruction, but chemical experiment at present to sample in bottle Cylinder mostly by a simple receptacle plus strong acid constitute.Soak or need operator to take plastic gloves when fishing for glass drying oven Throw in and fish for, be possible to splash strong acid liquid when so operating, there is certain danger for operator.On the other hand Because glass drying oven and sampling bottle have cavity to be difficult, often floating on liquid level in the sour cylinder of input causes glass drying oven and adopts Sample bottle inwall can not obtain good soaking and washing, want to make vessel sink to generally requiring to be pressed into device under liquid level manually Ware fills acid solution, and this also can bring certain danger to operator.

The content of the invention

The purpose of this utility model is the weak point for being currently being widely used sour cylinder, designs a kind of structure letter Experiment that is single, not only having can guarantee that operator safety but also can guarantee that the glass drying oven to be cleaned and the good immersion effect of sampling bottle acquisition Room acid cylinder.

For achieving the above object, chemical laboratory of the present utility model vapour-pressure type acid cylinder, including contain sour container, inflated type Air bag and vessel frame, the inflatable airbag be arranged on contain sour container in bottom, contain sour container in air bag obtain overhung can The vessel frame of taking-up, vessel frame bottom is netted engraved structure.

Further, the inflatable airbag also includes trachea and air pump, and the inflatable airbag is by trachea and setting Containing the connection of the air pump outside sour container.

In order to carry out suspension fixation to vessel frame, vessel arch both sides are provided with two cross bars, and cross bar frame is containing acid appearance The both sides of device upper port, and fixed by screw means, vessel sash hanger is contained in sour container.

Further, gap is left between the vessel frame bottom and the inflatable airbag full of gas of suspension.

Further, the vessel frame also includes vessel pressing plate, and vessel platen shape is adapted with vessel frame bottom surface, is pressed in It is positioned over the top of the vessel to be cleaned of vessel inframe.

Further, the vessel pressing plate centre position arranges handle, and some through holes are arranged on vessel pressing plate.

In order to push down vessel to be cleaned, vessel pressing plate is ceramic material.

Further, sour container rectangular in cross-section is contained, vessel frame section is rounded.

In order to prevent long-time immersion corrosion, inflatable airbag and material that trachea is anti-acid corrosion in acid solution.

This utility model has the advantage that compared to existing technology：

Chemical laboratory of the present utility model vapour-pressure type acid cylinder, the height for changing acid solution in Sheng sour container by air bag reaches Immersion, cleaning experiment room vessel, it is simple to operate.Without the need for vessel are put into into acid solution, splashing, and staff is caused not to need and acid solution Directly contact, vessel pressing plate can ensure that vessel will not float, and whole cleaning process is more safe efficient.Meanwhile, without the need for dragging for Clean vessel are taken, secondary pollution will not be caused to acid solution.

In figure, 1- air pumps, 2- tracheas, 3- contains sour container, 4- crockery baskets, 5- cross bars, 6- vessel pressing plates, 7- inflated type gas Capsule.

Specific embodiment

Such as Fig. 1, the chemical laboratory vapour-pressure type acid cylinder of the present invention, mainly by air pump 1, trachea 2, Sheng sour container 3, vessel Frame 4, vessel pressing plate 6 and inflatable airbag 7 are constituted.

It is agent structure of the present utility model wherein to contain sour container 3, and inflatable airbag 7 is placed on the bottom contained in sour container 3 Portion, is contained sour container 3 and is connected by the air pump 1 of trachea 2 and outside, and trachea 2 ensures sealing from extended position in sour container 3 is contained, and And inflatable airbag 7 and the long-time of trachea 2 and acid solution contact, made using anti-acid corrosion material.

The bottom of vessel frame 4 is netted hollow out, and side is complete side walls or adopts frame structure, and top both sides arrange two Cross bar 5, two framves of cross bar 5 are containing the upper port of sour container, and Sheng sour container is fixed on by screw means respectively in two cross bars 5 On 3, by whole vessel frame 4 be suspended on Sheng sour container 3 in, the distance from bottom of crockery basket 4 contain the bottom about 50cm of sour container 3 away from From, and height when ensureing that the bottom surface of vessel frame 4 is slightly above 7 gassy of inflatable airbag.

As Fig. 2, the shape of vessel pressing plate 6 are consistent with the bottom surface of vessel frame 4, centre position arranges handle, random on vessel pressing plate Some through holes are set, after vessel to be cleaned are placed in vessel frame 4, vessel pressing plate 6 are covered on vessel, vessel pressing plate 6 is Ceramic material, is pushed down vessel to be cleaned by own wt.

When this utility model is used, first the inflatable airbag 7 of unaerated state is placed into into Sheng sour container 3 bottom, then Vessel frame 4 is hung and is fixed in Sheng sour container 3, after completing to fix, acid solution is poured in Sheng sour container 3, acid solution is covered does not fill The air bag of gaseity, and liquid level is slightly below the bottom position of vessel frame 4.

During cleaning, first vessel to be cleaned are put in vessel frame 4, then cover vessel pressing plate 6 on vessel frame 4, by It is ceramic material in vessel pressing plate 6, quality is higher, can push down vessel to be cleaned, prevents it from floating.Cover vessel pressing plate Afterwards, then with air pump 1 inflatable airbag 7 is inflated, inflatable airbag 7 is constantly expanded due to filled volume, and volume is continuous The extruding of inflatable airbag 7 acid solution of increase forces acid solution face to rise, acid solution just through the netted hollow out of crockery basket 4 bottom by vessel Immersion acid solution, the through hole on vessel pressing plate can ensure that acid solution can be totally submerged vessel to be cleaned.

After the immersion of some time, gas in inflatable airbag 7 is extracted out with air pump, air bag volume is gradually reduced While acid solution face drop to below the bottom of crockery basket 4, the vessel that complete of cleaning are taken out.All in acid solution when so picking and placeing vessel It is more than face operation will not cause to splash acid solution because of operational error, on the other hand without by crockery basket 4 bring out Sheng sour container can The acid solution being attached in crockery basket 4 is avoided to drip on the ground.

If necessary to change the anti-corrosion air bag 7 for containing the bottom of sour container 3, can be pulled down crockery basket by screwdriver is carried out more Change.
