Analyzing and be commonly used for that process some instability or that avoid using filter paper filtering reagent and precipitation, high temperature is done
Dry, be ashed or weigh.Glass sand core crucible is the important utensil of one of laboratory filtration treatment different material.
In some detection projects, the sample in glass sand core crucible to carry out various different process, glass
Glass sand core crucible is generally put on the plug of bottle,suction direct sucking filtration so that taking.But owing to crucible makes
Easily there is crucible bottom out-of-flatness defect in process, is in use difficult to distinguish；Crucible is placed in bottle,suction plug
On, crucible bottom easily makes plug deformation or damage to the extruding of plug upper surface.Therefore, crucible bottom with
Often can there is space in bottle,suction chewing gum plug surface, it is difficult to reach to combine closely, cause vacuum to drop during sucking filtration
Low, the sucking filtration used time extends, and reduces detection efficiency.In this case, as changed glass sand core crucible, earthenware
Sample transfer easily loss in crucible, causes detection error.Change bottle,suction plug not only to waste time and energy, and
The problem that filtering velocity is slow can not be fully solved.Under the conditions of plug and sealed crucible are tight, a sample filtering
Process and generally complete within a few minutes；When both seal the best, it is the longest that the sucking filtration of a sample processes the used time
Reached for ten a few minutes, be three, four times of normal sucking filtration used time.If sample treatment needs to rinse sucking filtration repeatedly,
Above-mentioned situation has a strong impact on detection efficiency, it is impossible to adapt to the detection analysis of batch sample, and vacuum pump is long
Time operating is the most easily broken down.
Glass sand core crucible is placed on the plug of bottle,suction, does not has special fixing device, easily topples over, inspection
Survey personnel can only fixing crucible by hand pressure, reduces the space between crucible bottom and plug, reduces gas leakage,
But it is difficult to solution problem.This filter operation is the most time-consuming, it is difficult to be applicable to the detection of batch sample
Analyze.
The information being disclosed in this background section is merely intended to increase the reason of the general background to the present invention
Solve, and be not construed as recognizing or imply in any form that this information structure is for this area general technology
Prior art well known to personnel.
Summary of the invention
It is an object of the invention to provide a kind of crucible Suction filtration device, thus overcome crucible bottom out-of-flatness to lack
Fall into and the situation such as plug deformation or damage causes blow-by between crucible and plug, cause sucking filtration inefficient
Problem, and crucible is without fixing device, the most hand-held problem being placed on bottle,suction chewing gum beyond the Great Wall.
For achieving the above object, the invention provides a kind of crucible Suction filtration device, including: crucible, this earthenware
Being provided with filter course in crucible, described crucible bottom is provided with crucible plug, and this crucible plug is positioned at described filter course
Lower section, described crucible plug is provided with through hole；Bottle,suction, it is located at the lower section of described crucible, described
The bottle mouth position of bottle,suction is provided with sealing bottle,suction plug, and described bottle,suction plug is provided with through hole；Connecting tube,
It is through the through hole on described crucible plug and the through hole on described bottle,suction plug, described connecting tube upper end
Extending to below described crucible filter course, the mouth of pipe of described connecting tube upper end is concordant or is less than described crucible glue
Surface beyond the Great Wall, lower end extends in described bottle,suction, described crucible and described bottle,suction is connected；
And vacuum pump, it is connected with described bottle,suction.
Preferably, in technique scheme, the external diameter of described connecting tube is more than leading on described crucible plug
The internal diameter of the through hole on hole and described bottle,suction plug.
Preferably, in technique scheme, on through hole on described crucible plug and described bottle,suction plug
Through hole be concentric holes.
Preferably, in technique scheme, described crucible is sand core crucible.
Compared with prior art, there is advantages that the crucible Suction filtration device of the present invention,
By crucible bottom to be filtered just to the bottle,suction plug on sucking filtration bottleneck, clog at the bottom of crucible with crucible plug
Portion, by connecting tube through the through hole on crucible plug and bottle,suction plug, fixes crucible and bottle,suction
It is connected.Start vacuum-pump power supply switch, produce certain under bottle,suction, connecting tube, crucible filter course
Vacuum, crucible core filter course upper liquid pass through crucible filter course, by connecting tube, inflow is taken out
In filter flask.Because each sealing joint is good, air tight, sucking filtration efficiency maximizes.Overcome crucible bottom not
The situations such as the deformation of smooth or bottle,suction plug or damage on affect air-tightness, the problem of reduction filter efficiency,
And because crucible is connected as a single entity by connecting tube with bottle,suction, sucking filtration fixes crucible without testing staff by hand pressure.
The present invention effectively overcomes crucible and the plug impact on sucking filtration effect, maximally utilises vacuum pump efficiency
Can, save manpower and resource.The present invention makes simply, easy to operate and safe, time saving and energy saving.
