Description
Technical field
The utility model relates to a kind of suction filtration device, particularly relates to a kind of suction filtration device of synthetic coloring matter purification use.
Background technology
In food, artificial synthetic coloring matter uses polycaprolactam method to extract conventionally, and makes the aqueous solution, for high efficiency liquid phaseChromatograph detects. In colouring agent extracts, we blunge sample and Silon, obtain filter cake by suction filtration,The washing of methyl alcohol for filter cake-formic acid solution, removes the natural colouring matter in sample, then colouring agent is entered with ethanol-ammoniacal liquor-aqueous solutionRow wash-out dissociates, and collects eluent, by processing, for detecting.
In traditional operating process, must prepare two bottle,suctions and wash respectively and two steps of wash-out, or washingComplete, wash clean bottle,suction, then carry out wash-out operation, complex operation, easily produces cross pollution.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of suction filtration device of synthetic coloring matter purification use, colouring agentWashing and wash-out operation are used a bottle,suction to complete, simple to operate, can not produce cross pollution.
The utility model solves technical scheme that its technical problem adopts and is to provide a kind of synthetic coloring matter and purifies the suction filtration of useDevice, comprise bottle,suction and filter tunnel, described filter tunnel is fixed on the bottle mouth position of bottle,suction by sealing plug, described in take outFilter flask inside is provided with eluent channel, and described eluent channel top is fixed on the bottle mouth position of bottle,suction and is partial to bottle,suction bottleMouthful a side, the bottom of eluent channel from the bottle wall of bottle,suction pass, the liquid outlet of eluent channel is positioned at bottle,suctionPortion, described eluent channel is positioned at bottle,suction outside and is provided with the first valve.
As the utility model one preferred embodiment, described filter tunnel is sand core funnel.
As the utility model another preferred embodiment, described sealing plug adopts rubber stopper.
As the utility model another preferred embodiment, described bottle,suction is provided with discharging near the sidewall of bottom positionPassage, tapping channel is provided with the second valve.
As the improvement to this preferred embodiment, the discharging opening of described tapping channel straight down.
As the further improvement to this preferred embodiment, described bottle,suction bottom is arranged to along tapping channel lower limbThe acclivitous structure of opposite side of position to bottle,suction bottom.
As the further improvement to this preferred embodiment, described the second valve is polytetrafluoroethylene (PTFE) valve.
As the utility model another preferred embodiment, the liquid outlet of described eluent channel straight down.
As the utility model another preferred embodiment, described the first valve is polytetrafluoroethylene (PTFE) valve.
Beneficial effect
Bottle,suction of the present utility model inside is provided with an eluent channel, and eluent channel top is positioned at one of bottle,suction bottleneckSide, bottom passes from bottle,suction bottle wall, and eluent channel liquid outlet is positioned at bottle,suction outside, in the time carrying out washing operation,The cleaning solution of filter tunnel is directly evacuated in bottle,suction, in the time carrying out wash-out operation, adjusts the position of filter tunnel to eluentPassage suitable for reading, eluent directly flows in eluent channel, after pressure release, by opening the second valve, eluent is collected.Therefore, the utility model has been realized the washing of colouring agent and wash-out and is operated in and under the prerequisite that does not need wash bottle, use a bottle,suctionComplete, simple to operate, effectively avoid cross pollution.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model. Should be understood that these embodiment are only for illustrating this realityWith novel and be not used in restriction scope of the present utility model. In addition should be understood that read content that the utility model lectures itAfter, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application equallyAppended claims limited range.
A kind of synthetic coloring matter as shown in Figure 1 purifies the suction filtration device of use, comprises bottle,suction 3 and filter tunnel 1, filtersFunnel 1 adopts sand core funnel conventionally, is fixed on the bottle mouth position of bottle,suction 3 by sealing plug 2, according to experiment needs, filtersFunnel 1 can be replaced according to different size size requirements, and in laboratory, sealing plug 2 normally adopts rubber stopper.
Bottle,suction 3 inside are provided with eluent channel 5, and eluent channel 5 tops are fixed on the bottle wall of bottle,suction 3 bottle mouth positions,One side of position deflection bottle,suction 3 bottlenecks of eluent channel 5, its entrance is positioned at bottle,suction 3 inside. Eluent channel 5Bottom from bottle,suction 3 bottle a wall pass, its liquid outlet is positioned at the outside of bottle,suction 3, liquid outlet arranges straight down, washesDe-liquid passage 5 is positioned at bottle,suction 3 outsides, and to be provided with the first valve 6, the first valves 6 be polytetrafluoroethylene (PTFE) valve.
