Description
Technical field
The utility model relates to the extraction equipment technical field of chemical experimental instrument, particularly relates to a kind of filtering type solid-phase extraction device of efficient stable.
Background technology
Solid-phase extraction column is utensil common in chemical pretreatment process, market there is the one-tenth capo much filled, save the worry oneself loaded, but owing to being disposable pillar, use cost is very large, so it is the mode of saving cost and having flexibility concurrently that pillar is loaded in laboratory oneself.In use; the impurity that solid-phase extraction column often can be brought into because of sample itself or other factors; natural filtration process is caused slowly even to stop; common laboratory can carry out filtration cleaning with rubber pipette bulb or other artificial means of intervention to solid-phase extraction column; but above-mentioned cleaning way not only efficiency is low, and cleaning is not comprehensive, and some dead angles are difficult to cleaning and put in place; solid-phase extracting instrument does not wash clean clearly, and cleaning performance is poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of filtering type solid-phase extraction device of efficient stable, solves existing phase abstraction instrument manual cleaning efficiency low, and cleaning is not comprehensive, is difficult to the problem cleaned up.
The utility model is achieved through the following technical solutions: a kind of filtering type solid-phase extraction device of efficient stable, comprise loading pipe portion, the column tube portion in bonding pad pipe portion, the flow control valve connecting column tube portion, the amplification bottle pipe that is connected with flow control valve, it is characterized in that, the upper end in described column tube portion is communicated with the bottom in loading pipe portion, and the lower end in column tube portion is connected with the upside valve face of flow control valve, the described upper end mouth of pipe of amplification bottle pipe is connected with the downside valve face of flow control valve, and amplifies the small-bore woven hose of cross-under in bottle pipe.
Further, described column tube portion and amplification bottle pipe are arranged on same body central axis.
Further, by outer tube body and cross-under, the manual spool in outer tube body forms described flow control valve.
Further, the lower end mouth of pipe of described amplification bottle pipe arranges connection ground, and the bottle tube wall face, side of amplifying bottle pipe is arranged inner with bottle pipe be communicated with vacuumize suction nozzle.
Further, the described small-bore woven hose upper end mouth of pipe is connected to flow control valve, and the lower end mouth of pipe extends to the lower end interface connecting ground.
Compared with prior art, the beneficial effects of the utility model are: the utility model has been socketed amplification bottle pipe on the woven hose of the flow control valve bottom of solid-phase extracting instrument, and by amplifying bottle tube wall face, bottle pipe side vacuumizes suction nozzle, the body of flow control valve bottom is vacuumized, the pressure forming lower tube body on flow control valve is looked into, accelerate the wash liquid stream inflow-rate of water turbine control valve in flow control valve upper portion pipe body, impurity in upper portion pipe body is taken away fast, reach the object that cleaning and filtering accelerates flow control valve upper portion pipe body, avoid existing manual cleaning efficiency low, clean not comprehensive, clean sordid problem, device overall construction design is reasonable, cleaning operation is simple, cleaning overall effect is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the filtering type solid-phase extraction device of a kind of efficient stable of the utility model.
Wherein: 1, loading pipe portion; 2, column tube portion; 3, flow control valve; 4, manual spool; 5, bottle pipe is amplified; 6, ground is connected; 7, suction nozzle is vacuumized; 8, outer tube body; 9, small-bore woven hose.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model relates to a kind of filtering type solid-phase extraction device of efficient stable, comprise loading pipe portion 1, the column tube portion 2 in bonding pad pipe portion 1, connect the flow control valve 3 in column tube portion 2, the amplification bottle pipe 5 be connected with flow control valve 3, the upper end in described column tube portion 2 is communicated with the bottom in loading pipe portion 1, and the lower end in column tube portion 2 is connected with the upside valve face of flow control valve 3, the described upper end mouth of pipe of amplification bottle pipe 5 is connected with the downside valve face of flow control valve 3, and amplify the small-bore woven hose 9 of cross-under in bottle pipe 5, described column tube portion 2 and amplification bottle pipe 5 are arranged on same body central axis, by outer tube body 8 and cross-under, the manual spool 4 in outer tube body 8 forms described flow control valve 3, the lower end mouth of pipe of described amplification bottle pipe 5 arranges and connects ground 6, and the bottle tube wall face, side of amplifying bottle pipe 5 is arranged inner with bottle pipe be communicated with vacuumize suction nozzle 7, the described small-bore woven hose 9 upper end mouth of pipe is connected to flow control valve 3, the lower end mouth of pipe extends to the lower end interface connecting ground 6.
In sum, during the cleaning of the utility model device, first close flow control valve 3, cleaning fluid is added in column tube portion 2 from the mouth of pipe in loading pipe portion 1, liquid to be cleaned adds well, suction nozzle 7 is vacuumized by taking out pump connection, amplification bottle pipe 5 is vacuumized, now between the loading pipe portion 1 on flow control valve 3 top and the amplification bottle pipe 5 of column tube portion 2 and flow control valve 3 bottom, mineralization pressure is poor, now open flow control valve 3, cleaning fluid in loading pipe portion 1 and column tube portion 2 flows fast through solid-phase extracting instrument under the effect of gravity and pressure, finally flow into and be connected in the receiving flask that ground 6 connects with amplification bottle pipe 5 lower end, and repeat aforesaid operations repeatedly, realize solid-phase extracting instrument washing and filtering, wherein also in amplification bottle pipe 5, cross-under upper end is connected to the small-bore woven hose 9 of flow control valve 3, avoid cleaning fluid and be evacuated suction nozzle 7 sucking-off under the effect of the pressure, device overall construction design is reasonable, cleaning operation is simple, cleaning comprehensively not dead angle, avoid the inefficient problem of existing manual cleaning.
