Description
Technical field
The utility model relates to labware technical field, more particularly, relates to a kind of Drexel bottle of anti-suck.
Background technology
Drexel bottle is the instrument washing away impurity in gas more common in laboratory, its principle is the absorbing liquid gas containing impurity being passed into its inside, dissolve mutually between the two or chemical reaction occurs, thus the impurity of removing gas, to reach the object of Purge gas.The Drexel bottle generally used at present mainly comprises bottle and bottle cap two parts, bottle cap is provided with long duct and tubulature, and Drexel bottle is built with the liquid absorbing impurity, and long duct forms sealing system with bottleneck under extending into liquid and is connected.But in actual mechanical process, often due to react fast at the end of the gas of releasing in experimental provision reduce suddenly, the gas pressure in device is caused to reduce suddenly or other occurs unexpectedly, there is serious suck-back phenomenon to make absorbing liquid enter reaction bulb to cause the failure of an experiment, or, there is serious potential safety hazard in the generation of the situations such as burning, blast.
By patent retrieval, in prior art, existing related art scheme is open.As, Chinese Patent Application No.: 201220502085.X, the applying date: on September 28th, 2012, utility model name is called: a kind of Drexel bottle of anti-suck, this application case comprises bottle, air inlet pipe and escape pipe, air inlet pipe stretches into the below of bottle, escape pipe is connected to the top of bottle, the lower end that described air inlet pipe stretches into bottle is connected with the anti-suck chamber of a band bottom surface, the bottom surface in anti-suck chamber has multiple hole, the bottom surface in anti-suck chamber and the bottom noncontact of bottle, a float is provided with in the chamber in anti-suck chamber, the top of float is provided with the break-in face of matching with the necking down accent on the top in anti-suck chamber.Although this application case can prevent the solution suck-back in Drexel bottle from entering in reaction unit to a certain extent, anti-suck poor effect, and the speed of giving vent to anger of escape pipe is slow, thus causes washing gas gas collection insufficient.
