Description

Technical Field

[0001] The invention relates to the technical field of concentrators, in particular to an integrated vacuum concentrator. Background Art

[0002] The integrated vacuum concentrator is a device that uses a combination of centrifugal force, vacuum and heating to quickly evaporate the solvent in the sample. Its main function is to use the vacuum environment to reduce the boiling point of the solvent, thereby achieving rapid and efficient concentration of liquid samples. The integrated vacuum concentrator can be widely used in life sciences, DNA / RNA sample preparation, laboratory sample tissue concentration extraction, nucleosides, proteins, drugs, metabolites, enzymes or similar sample concentration. In addition, it can also be used in biology, microbiology, biochemistry, pharmaceutical research and analytical chemistry.

[0039] In the technical solution of this embodiment, by filling a certain amount of balancing weight liquid into the inner shell 35, before the use of the device or after a certain amount of the internal balancing weight liquid is consumed, the second micro pump 36 is started, and the second micro pump 36 inputs the balancing weight liquid in the inner shell 35 into the inner cavity of the annular shell 32 through the connecting pipe 34, and the balancing weight liquid in the inner cavity of the annular shell 32 enters the inner cavity of the fixed shell 5 through the through hole 33 on the side wall of the bottom shell 12, thereby realizing the filling and replenishment operation of the balancing weight liquid;

[0040] A sealing ring 14 is fixedly connected to the top surface of the round shell 3 and a cover plate 15 is arranged on the upper side. A connecting assembly 16 is arranged on the cover plate 15. The connecting assembly 16 includes a circular groove 37. Four circular grooves 37 are opened on the top surface of the concentrator host 1. Fifth springs 38 are fixedly connected in the circular grooves 37. The other ends of the fifth springs 38 are fixedly connected to connecting rods 39. The top ends of the two connecting rods 39 on the rear side are hingedly connected to the bottom surface of the cover plate 15. The top ends of the two connecting rods 39 on the front side are fixedly connected to a pressing plate 40. The pressing plate 40 is arranged on the top surface of the cover plate 15.

[0041] In the technical solution of this embodiment, before use, the cover 15 is closed, and the front connecting rod 39 is rotated so that the pressure plate 40 is pressed on the top surface of the cover 15. At this time, under the action of the fifth spring 38, the rear connecting rod 39 pulls the cover 15, and the front pressure plate 40 presses the cover 15, which can ensure the sealing effect between the cover 15 and the sealing ring 14.

[0042] Working principle: When the present invention is used, a certain amount of balancing weight liquid is firstly added into the inner shell 35, and the device is connected to an external power supply, and the second micro pump 36 is started. The second micro pump 36 inputs the balancing weight liquid in the inner shell 35 into the inner cavity of the annular shell 32 through the connecting pipe 34, and the balancing weight liquid in the inner cavity of the annular shell 32 enters into the inner cavity of the fixed shell 5 through the through hole 33 on the side wall of the bottom shell 12. When the inner cavities of the fixed shell 5 and the bottom shell 12 are filled with the balancing weight liquid, the operation of the second micro pump 36 is stopped to complete the pre-installation operation of the balancing weight liquid, and then the mounting shell 6 is sleeved and installed on the outer wall of the fixed shell 5, so that the active shell 5 and the bottom shell 12 are filled with the balancing weight liquid. The movable tube 18 is inserted into the side hole 17 on the side wall of the mounting shell 6 under the action of the first spring 20, and then the fixing nut 41 is screwed into the top surface of the fixing shell 5 to realize the positioning installation between the mounting shell 6 and the fixing shell 5, and then the reagent bottle containing the solution to be concentrated is installed in a symmetrical position and placed in the placement groove 9 on the placement plate 8. At this time, under the action of gravity, the placement plate 8 moves downward, and the placement plate 8 pushes the vertical rod 29, and the vertical rod 29 drives the displacement sensor 30 to move. The displacement sensor 30 measures the bottom surface distance of the mounting hole 28 and transmits the measured data to the control device inside the concentrator host 1. The control device is based on The displacement data of the symmetrical positions are compared and analyzed. The control device inside the concentrator host 1 starts the first micro pump 19 located on the side with larger data. The first micro pump 19 extracts the counterweight liquid from the inner cavity of the fixed shell 5. The counterweight liquid enters the first arc tube 21 and the second arc tube 22 through the movable tube 18. The counterweight liquid in the second arc tube 22 is injected into the counterweight bin 24. Under the action of the liquid pressure, the movable plate 26 is pushed. The movable plate 26 compresses the third spring 27. As the liquid inside the counterweight bin 24 increases, the placement plate 8 moves continuously, so that the placement plate 8 pushes the vertical rod 29 again, and the displacement sensor The device 30 continuously transmits the measured data to the control device inside the concentrator host 1. When the control device compares and analyzes and concludes that the data of the displacement sensors 30 on both sides are the same, the operation of the first micro pump 19 is stopped, and the weighting operation of the symmetrically placed plate 8 is completed. Then, the cover 15 is closed, and the front connecting rod 39 is rotated so that the pressure plate 40 is pressed on the top surface of the cover 15. At this time, under the action of the fifth spring 38, the rear connecting rod 39 pulls the cover 15, and the front pressure plate 40 presses the cover 15, which can ensure the sealing effect between the cover 15 and the sealing ring 14. The vacuum concentration operation can be realized by starting the concentrator host 1.
