Background
The part of the traditional Chinese medicine which can be utilized comprises roots, flowers, leaves, fruits or skins, and the traditional Chinese medicine extract is obtained by taking traditional Chinese medicines as raw materials through the steps of extraction, separation and the like. However, the flow rate during chromatographic separation is very small (the minimum flow rate is only 10-15ml per minute) during the separation of the traditional Chinese medicine, so that the online flow rate control is a great problem in the actual large-scale production.
SUMMERY OF THE UTILITY MODEL
To the current problem, the utility model aims at providing a controllable plywood separator of velocity of flow.
Therefore, the utility model adopts the following technical scheme: the laminated plate separation device with the controllable flow rate comprises a chromatographic separation column and is characterized by further comprising an eluent quantifying tank and a quantifying diaphragm pump, wherein the quantifying diaphragm pump is connected to the liquid outlet end of the chromatographic separation column through a pipeline; the relative height of the quantitative diaphragm pump is equivalent to the liquid level height of the eluent buffer layer.
As the supplement and improvement to the technical proposal, the utility model also comprises the following technical characteristics.
And the eluent quantifying tank is connected with an eluent replenishing pipe controlled by an automatic position control induction valve.
The eluent quantifying tank is also internally provided with a scale floating ball and a quantifying tank floating type liquid level scale, so that an operator can remotely observe the quantity of the solvent in the quantifying tank and master the liquid supplementing condition.
And a collecting tank is arranged below the outlet of the quantitative diaphragm pump.
The utility model discloses following beneficial effect can be reached: the utility model discloses a control out liquid flow at a liquid end installation ration diaphragm pump, chromatography column goes out liquid end and utilizes quantitative diaphragm pump (1-20L/h, sets up operating frequency and sets up corresponding flow) can ensure that chromatography separation process's velocity of flow is very stable to guarantee chromatography process's separation quality, to chromatography column upper eluant buffer layer liquid level height control at a fixed value (chromatography column goes out liquid end differential pressure unanimous), thereby make chromatography process go out liquid flow realize controlling steadily setting for the scope. The liquid outlet end of the chromatographic column can ensure the stable flow rate in the chromatographic separation process by utilizing a quantitative diaphragm pump (1-20L/h, and the running frequency is set to set the corresponding flow), thereby ensuring the separation quality in the chromatographic process.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the drawings, and the described embodiments are illustrative and explanatory of the present invention, and do not constitute the only limitations of the present invention.
As shown in fig. 1, the utility model relates to a controllable plywood separator of velocity of flow includes chromatography separation column 1, eluant constant volume jar 3 and quantitative diaphragm pump 2, the liquid outlet end of pipe connection in chromatography separation column is passed through to the quantitative diaphragm pump, eluant constant volume jar is connected in the top of chromatography separation column, the pipeline that eluant constant volume jar was connected with automatic accuse position induction valve 4 links into in the chromatography separation column, the top that the eluant lets in the chromatography separation column forms eluant buffer layer 11, the eluant buffer layer keeps at fixed liquid level through automatic accuse position induction valve, and be provided with low level sensor 5 at chromatography separation column correspondence eluant buffer layer department; the relative height of the quantitative diaphragm pump is equivalent to the liquid level height of the eluent buffer layer. The eluent quantifying tank is connected with an eluent replenishing pipe 8 controlled by an automatic position control induction valve. The inside of eluant quantification jar still is provided with scale floater 6, the floating liquid level scale of quantification jar, and the operator can observe the solvent quantity in the quantification jar remotely, masters the fluid infusion condition. A collecting tank 7 is arranged below the outlet of the quantitative diaphragm pump. The quantitative tank (20-150L) can be designed to be used in one day according to the requirements of chromatographic separation flow rate, only one time of eluent is needed to be supplemented every day, and a liquid level automatic sensing valve is installed when liquid is added every time, so that the valve can be automatically closed when the liquid reaches the specified volume. The floating liquid level scale of quantitative jar, the operator can observe the solvent quantity in the quantitative jar remotely, masters the fluid infusion condition. Eluent in the quantitative tank flows into the chromatographic column from the bottom liquid outlet, and the eluent buffer layer at the upper end of the chromatographic column can be well controlled at a certain fixed liquid level by the automatic induction control valve, so that the pressure difference at the liquid outlet end of the chromatographic column is ensured not to be changed. The liquid outlet end of the chromatographic column can ensure the stable flow rate in the chromatographic separation process by utilizing a quantitative diaphragm pump (1-20L/h, and the running frequency is set to set the corresponding flow), thereby ensuring the separation quality in the chromatographic process. The chromatographic column buffer layer is provided with a low liquid level sensor, if a low liquid level sensing signal appears in the buffer layer under special conditions, the buffer layer can transmit a signal to shut down the work of the liquid quantitative pump through the controller, and meanwhile, an alarm is sent out (mobile phone networking). The utility model discloses need not complicated program module ization design, the problem that drops into less, the cost is little can reach little velocity of flow control.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above.
