Description

Technical Field

[0001] This utility model relates to the field of nitrogen blowing concentration technology, and in particular to a nitrogen blowing concentrator. Background Technology

[0002] A nitrogen evaporator, also known as a nitrogen blow-dryer or automatic rapid concentrator, can rapidly, continuously, and controllably blow nitrogen onto the surface of heated samples, enabling rapid concentration of large quantities of samples. It can process multiple samples at once, offering significant advantages in repetitive experiments involving multiple factors and levels. The experimental operation is simple and flexible, allowing for unrestricted adjustment of the concentration process at any time.

[0003] For example, patent CN219265872U provides a nitrogen evaporator suitable for 96-well plates, relating to the field of nitrogen evaporator technology. The evaporator includes a plate placement block positioned at the center of the main body of the nitrogen evaporator, with a 96-well plate placement groove at its upper end. Limiting blocks are located on both sides of the 96-well plate placement groove, and these limiting blocks are fixedly connected to the plate placement block via limiting springs. An anti-slip pad is located on the other side of the limiting blocks and is adhesively connected to them. Both sides of the limiting blocks have inclined grooves. A fixing column is located on one side of the plate placement block, and the fixing column is an integral structure with the plate placement block. This nitrogen evaporator suitable for 96-well plates facilitates the placement of the 96-well plate through the design of the 96-well plate placement groove. The combined design of the limiting springs, limiting blocks, and anti-slip pads makes it easier to limit the placement of the 96-well plate.

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0035] like Figure 1-4 As shown, an embodiment of this utility model provides a nitrogen blowing concentrator, which includes: a shell 1, a support 2, a water tank assembly 3, a lifting assembly 4, and a nitrogen blowing assembly 5. The shell 1 is fixed to the outside of the support 2. The water tank assembly 3 includes a water tank body 31 and a water tank heating element 32. The water tank body 31 is located below the support 2, and the water tank heating element 32 is located inside the water tank body 31 for heating the liquid inside the water tank body 31. The lifting assembly 4 is fixed to the support 2 and has a lifting end that can be raised and lowered in a vertical direction. The nitrogen blowing assembly 5 includes a carrier plate 51, a dispersion tube 52, a plurality of nitrogen blowing needles 53, and a gas heating element. The carrier plate 51 is fixed to the lifting end, and the dispersion tube 52 is fixed to the carrier plate 51. The dispersion tube 52 has an inlet for supplying nitrogen to the outside and an outlet corresponding to each of the nitrogen blowing needles 53. The gas heating element is located inside the dispersion tube 52 for heating the gas flowing through the dispersion tube 52.

[0036] In use, the liquid to be concentrated is placed in a test tube and then placed in the water tank body 31. The water tank heating element 32 heats the liquid in the water tank body 31, so that the liquid to be concentrated in the test tube is heated. Next, the lifting component 4 drives the nitrogen blowing component 5 to descend, so that the nitrogen blowing needle 53 extends into the test tube. Nitrogen gas passes through the dispersion tube 52 and is heated by the gas heating element, and then blown into the test tube through the nitrogen blowing needle 53. The heated nitrogen gas can heat the liquid in the test tube, which can improve the concentration efficiency of the liquid in the tube.

[0037] In this utility model, a water tank heating element and a gas heating element are provided. The water tank heating element is used to heat the liquid in the water tank body 31 to achieve water bath heating of the test tube. The gas heating element is used to heat the nitrogen gas blown into the test tube. The heated nitrogen gas can heat the liquid in the test tube. Compared with the prior art that only relies on water bath heating, the solution of this application adopts both water bath and gas heating methods, which can effectively improve the concentration efficiency of the liquid in the tube.

[0038] Specifically, the outer shell 1 is used to encapsulate the bracket 2, the water tank assembly 3, the lifting assembly 4, and the nitrogen blowing assembly 5 into a closed box, which helps to limit heat loss and can effectively improve the concentration efficiency of the liquid in the tube.

[0039] Specifically, the water tank assembly 3 includes a water tank body 31 and a water tank heating element 32. The water tank body 31 is located below the support 2, and the water tank heating element 32 is located inside the water tank body 31 and is used to heat the liquid inside the water tank body 31.

[0040] Furthermore, the water tank body 31 is a box without a top cover, and the water tank heating element 32 is at least partially disposed inside the water tank body 31 and immersed in the liquid in the water tank body 31.

[0041] The function of the water tank heating element 32 is to heat the liquid inside the water tank body 31. Therefore, it only needs to meet the above function and its specific structure does not need to be limited. In some feasible embodiments, the water tank heating element 32 includes a semiconductor heating plate, which is disposed on the inner wall of the water tank body 31. When energized, the semiconductor heating plate generates heat to heat the liquid inside the water tank body 31. In this embodiment, the water tank heating element 32 includes a heating wire, one end of which is located inside the water tank body 31, and the other end extends to the outside of the water tank body 31 and is connected to a power source. When energized, the heating wire generates heat to heat the liquid inside the water tank body 31.

[0042] Furthermore, the water tank assembly 3 also includes a translation component 33, which is fixed on the bracket 2 and has a translation end. The water tank body 31 is fixed to the translation end. The translation component 33 is used to drive the water tank body 31 to move relative to the outer shell 1, so as to facilitate the operator to pick up and put down the test tubes in the water tank body 31.

[0043] Correspondingly, the outer shell 1 includes a fixed part 11 and a split part 12. The fixed part 11 is fixed on the outside of the bracket 2, and the split part 12 is fixed on the water tank body 31. When the translation component 33 is used to drive the water tank body 31 to retract into the bracket 2, the split part 12 and the fixed part 11 are spliced ​​together to form a whole.

[0044] Furthermore, the translation component 33 includes a translation slide rail 331 and a translation slider. The translation slide rail 331 is horizontally disposed at the bottom of the bracket 2. The translation slider is slidably connected to the translation slide rail 331 and can stop at any position within its sliding stroke. The water tank body 31 is fixed to the translation slider. The translation slider slides along the translation slide rail 331, causing the water tank body 31 to extend out of or retract into the outer shell 1.

[0045] Specifically, the lifting assembly 4 includes a motor 41 and a screw 42. The motor 41 is fixed on the bracket 2, and the screw 42 is arranged vertically, with one end fixed to the output end of the motor 41 and the other end threadedly connected to the carrier plate 51. In use, the motor 41 drives the screw 42 to rotate in both directions, thereby driving the carrier plate 51 to rise and fall along the screw 42.

[0046] Furthermore, the lifting assembly 4 also includes a guide assembly 43, which is connected to the carrier plate 51 and the bracket 2, and is used to guide the lifting direction of the carrier plate 51.

[0047] Furthermore, the guiding component 43 includes a guide rail 431 and a slider 432. The guide rail 431 is fixed vertically on the bracket 2, and the slider 432 is slidably connected to the guide rail 431 and fixed to the carrier plate 51. The slider 432 can slide along the guide rail 431, thereby guiding the lifting direction of the carrier plate 51 so that it can always maintain vertical lifting.

[0048] Specifically, the nitrogen blowing assembly 5 also includes an exhaust device 54, which is fixed on the bracket 2 and is used to exhaust the gas from the nitrogen blowing concentrator in order to maintain stable gas pressure inside the nitrogen blowing concentrator.

[0049] Furthermore, the exhaust device 54 includes an exhaust fan 541, a first hose 542, and a second hose 543. The exhaust fan 541 is fixed on the bracket 2. One end of the first hose 542 is connected to the vent on the outer casing 1, and the other end is connected to the exhaust outlet of the exhaust fan 541. The second hose 543 is fixed on the bracket 2. One end of the second hose 543 is connected to the intake of the exhaust fan 541, and the other end of the second hose 543 extends above the water tank body 31.
