Description
Technical Field
The utility model relates to the technical field of synergistic degassing and empty liquid detection equipment, in particular to a synergistic degassing and empty liquid detection combined device.
Background
In high pressure liquid chromatography, high pressure pumps are used to push reagents and samples into the chromatography columns. When dissolved gas in the liquid overflows when the temperature is increased, bubbles are mixed in a liquid inlet pipeline of the high-pressure pump, and the base line of the chromatogram is abnormal, so that the analysis result is influenced. When small bubbles are accumulated into large bubbles or the reagent is used up to cause the liquid inlet pipeline of the high-pressure pump to be mixed with large-section gas, the high-pressure pump cannot suck liquid and needs to be stopped for manual air suction.
At present, the industry generally adopts a method for degassing a reagent on line and monitoring the residual quantity of the reagent. The on-line degassing method alone does not allow the dissolved bubbles to escape prematurely. The monitoring of the reagent allowance is not the direct monitoring of the bubbles in the pipeline, and the bubble entering caused by the air leakage of the pipeline has no monitoring effect.
Therefore, a combined device for synergistic degassing and empty liquid detection is provided.

FIG. 1 is a schematic view of the structure of the present invention.
In the figure: the device comprises a liquid inlet 1, an adapter 2, a liquid outlet 3, a stainless steel pipe 4, a breathable membrane pipe 5, a heating plate 6, a closed negative pressure chamber 7, a membrane pump 8, a negative pressure sensor 9 and a temperature sensor 10.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to the attached figure 1, the combined device for synergistic degassing and empty liquid detection comprises a closed negative pressure chamber 7, a heating plate 6 and a breathable membrane tube 5 wound into a plurality of circles are arranged in the closed negative pressure chamber 7, a stainless steel tube 4 is arranged on the heating plate 6, the stainless steel tube 4 is communicated with the breathable membrane tube 5, the liquid outlet end of the breathable membrane tube 5 extends out of the closed negative pressure chamber 7 and is communicated with a liquid outlet 3, and an adapter 2 is arranged between the stainless steel tube 4 and the breathable membrane tube;
the liquid inlet end of the stainless steel pipe 4 penetrates through the closed negative pressure chamber 7 to be connected with the liquid inlet 1, and after the reagent flows into the stainless steel pipe 4 from the liquid inlet 1, the reagent enters the multi-circle breathable membrane pipe 5 through the adapter 2 and finally flows out of the liquid outlet 3.
The closed negative pressure chamber 7 is also provided with a temperature sensor 10 for monitoring the temperature of the heating plate 6 in real time;
a negative pressure sensor 9 for detecting the pressure in the closed negative pressure chamber 7 is arranged on the closed negative pressure chamber 7;
meanwhile, the diaphragm pump 8 is connected to the side wall of the closed negative pressure chamber 7 in a through mode through a pipeline, and the side wall of the closed negative pressure chamber is communicated with the closed negative pressure chamber 7 through an air suction port of the diaphragm pump 8 to continuously suck indoor air and keep indoor negative pressure.
This device is through heating stainless steel pipe 4, lets the bubble of dissolving in the reagent accelerate in advance to spill over. Then the air permeable membrane tube 5 is sucked out of the tube under the negative pressure environment. When a large section of gas is introduced due to light of the reagent or gas leakage of the pipeline, a large amount of gas in the gas-permeable membrane tube 5 is sucked into the negative pressure chamber, so that the negative pressure changes rapidly. Therefore, the method can judge that a large amount of gas is introduced into the pipeline, alarm in time or adopt other technical means to prevent abnormal states.
The working steps are as follows:
1. the heating plate 6 works to heat the stainless steel pipe 4 positioned therein;
2. the temperature sensor 10 operates to detect the temperature of the heating plate 6 in real time.
3. The diaphragm pump 8 operates, and it sucks air from the negative pressure chamber 7 and discharges it, maintaining the negative pressure therein.
4. The pressure sensor 9 works to detect the pressure in the negative pressure chamber 7 in real time.
5. When the reagent flows in from the liquid inlet 1, the reagent enters the heated stainless steel pipe 4. The dissolved gases in the reagent are heated to accelerate the escape.
6. When the reagent and the overflowed bubbles enter the multi-circle breathable membrane tube 5 at the same time, the negative pressure in the vacuum negative pressure chamber 7 sucks out the gas in the breathable membrane tube, and the change of the indoor negative pressure is detected by the pressure sensor 9.
7. When the change of the indoor negative pressure is small, the state is judged to be a normal degassing state. When the indoor negative pressure changes rapidly, the film tube is judged to have a large amount of gas, probably reagent light or pipeline air leakage, and an alarm is given in time or other technical means are adopted to prevent abnormal states.
