Description

Technical Field

[0001] The utility model relates to the technical field of solvent removal, in particular to a device for removing solvent from trace samples. Background Technique

[0002] Desolventizing agent refers to a chemical reagent used to remove and separate solvents contained in certain substances. In some scientific experiments, in order to separate one or several organic compounds from a certain mixture, a desolventizing agent is needed to separate it from other substances. In laboratories or industrial production, desolventizing agents also have extensive applications.

[0003] During the sample processing process, especially during the processing of trace samples, it is often necessary to remove the solvent in the samples. Currently, the more common processing method is to remove the solvent by means of decompression. Since trace samples need to be placed upside down in a sample bottle with a small volume, it is difficult to remove the solvent in the sample bottle by decompression. Due to the small volume of the sample bottle, it is difficult to achieve decompression treatment of the small-volume solvent bottle containing trace samples without using a large-volume solvent bottle. At the same time, during the sample processing process, it is often necessary to remove the solvent from a large number of samples, which is not only cumbersome but also has low removal efficiency.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1 - 8, A micro-sample solvent removal device, comprising a cylinder body 1 and a cylinder cover 2. The number of cylinder bodies 1 is set to seven. A heat-conducting cylinder 3 is sleeved on the outer surface of each cylinder body 1. Two groups of clamping components 15 are installed on the inner wall of each cylinder body 1. The number of each group of clamping components 15 is six. The cooperation of multiple clamping components 15 can clamp the sample solvent bottle, and the clamping stability is relatively high. Each clamping component 15 is composed of two fixing blocks 151, a fixing shaft 152, two scroll elastic members 153 and an arc-shaped plate 154. The two fixing blocks 151 are both fixedly connected to the cylinder body 1. One ends of the two fixing blocks 151 and the arc-shaped plate 154 are all circular and are all hollow. One ends of the two scroll elastic members 153 are respectively fixedly connected to the two fixing blocks 151. The other ends of the two scroll elastic members 153 are both fixedly connected to the fixing shaft 152. The scroll elastic member 153 is in a state of storing energy. The fixing shaft 152 is fixedly connected to the arc-shaped plate 154. The arc-shaped plate 154 is arc-shaped. The elastic deformation of the scroll elastic member 153 can enable the arc-shaped plate 154 to clamp the sample solvent bottle, and the clamping component 15 can automatically clamp sample solvent bottles of different sizes, with relatively high flexibility. A vacuum tube 4 is fixedly communicated with the upper surface of the cylinder cover 2. The upper end of the vacuum tube 4 is connected to an external vacuum pump for pumping vacuum to achieve the purpose of decompression. Decompression to remove organic solvents can reduce the boiling point of organic solvents by reducing the environmental pressure.Thus, the rapid separation of the organic solvent is achieved. A partition plate 5 is fixedly connected to the upper ends of multiple heat conduction cylinders 3. A sealing groove 19 is formed on the upper surface of the partition plate 5. A sealing gasket 20 is fixedly connected to the bottom surface of the cylinder cover 2. Both the sealing groove 19 and the sealing gasket 20 are annular, and the sealing groove 19 is adapted to the sealing gasket 20. When the sealing gasket 20 descends, it can be inserted into the sealing groove 19 to play a sealing role and prevent external gas from entering between the cylinder cover 2 and the partition plate 5. A water bath tank 6 is fixedly connected to the bottom surface of the partition plate 5, and the water inside the water bath tank 6 can be heated. Sealing rings A14 are installed between multiple heat conduction cylinders 3 and multiple cylinders 1 respectively. Multiple sealing rings A14 are fixedly connected to multiple heat conduction cylinders 3 respectively, and multiple cylinders 1 are in close contact with multiple sealing rings A14 respectively, improving the stability between the cylinder 1 and the heat conduction cylinder 3, and further preventing the water in the water bath tank 6 from escaping from between the cylinder 1 and the heat conduction cylinder 3. An electric heating wire A16 is fixedly installed on the inner bottom wall of the water bath tank 6. The electric heating wire A16 is in a scroll shape. An electric heating wire B17 is fixedly installed on the inner side wall of the water bath tank 6. The electric heating wire B17 is in a spiral shape. After the electric heating wire A16 and the electric heating wire B17 are powered on, they can heat the water inside the water bath tank 6, which is beneficial to achieving the rapid separation of the organic solvent. A chassis 7 is slidably connected to the inner wall of the water bath tank 6. Each cylinder 1 is fixedly connected to the chassis 7. Multiple water inlet holes 8 are formed inside the chassis 7. Multiple push rods 9 arranged in a circular pattern are fixedly connected to the upper surface of the chassis 7. A sealing ring B18 is installed at the intersection of each push rod 9 and the partition plate 5. Each sealing ring B18 is fixedly connected to the partition plate 5 and is in close contact with the adjacent push rod 9, improving the sealing performance between multiple push rods 9 and the partition plate 5 and preventing the water in the water bath tank 6 from escaping from the gap between the push rod 9 and the partition plate 5. Each push rod 9 is inserted into the partition plate 5. Multiple pressing covers 10 are fixedly connected to the bottom surface of the cylinder cover 2. Multiple push rods 9 are respectively inserted into multiple pressing covers 10. Multiple springs 11 are fixedly connected between the partition plate 5 and the chassis 7. Each spring 11 is in a static state. Multiple push rods 9 are respectively located inside multiple springs 11. A threaded cylinder 12 is fixedly connected to the outer surface of the partition plate 5. A threaded cover 13 is rotatably connected to the outer surface of the cylinder cover 2. The threaded cover 13 can be screwed into the threaded cylinder 12 to play a role in fixing the partition plate 5 and the cylinder cover 2.,

[0027] During use, first insert the sample solvent bottle into the cylinder 1 and make contact with multiple clamping components 15, and squeeze multiple arc-shaped plates 154. When multiple arc-shaped plates 154 are stressed and rotate, the scroll elastic member 153 starts to store energy, enabling the arc-shaped plates 154 to be in close contact with the sample solvent bottle, thereby achieving the purpose of clamping the sample solvent bottle by multiple clamping components 15. Moreover, the angle of the arc-shaped plates 154 changes with the bottle body size of the sample solvent bottle, so as to be able to clamp and fix sample solvent bottles of different sizes.

[0028] Next, rotate the threaded cap 13 downward to threadedly connect the threaded cap 13 to the threaded cylinder 12, improving the stability between the threaded cap 13 and the threaded cylinder 12. At this time, the gasket 20 is inserted into the sealing groove 19, and multiple pressing caps 10 respectively push multiple push rods 9 downward. The multiple push rods 9 drive the chassis 7 downward. At this time, the multiple springs 11 are in a stretched state. The chassis 7 drives the multiple cylinders 1 to descend along the multiple heat-conducting cylinders 3 respectively. The cylinder 1 can enter the bottom of the water bath tank 6, and the water inside the water bath tank 6 is heated by the heating wire A 16 and the heating wire B 17, which is beneficial to the rapid separation of the organic solvent. The water temperature at the bottom of the water bath tank 6 is relatively high. When the cylinder 1 enters the bottom of the water bath tank 6, the separation efficiency of the solvent can be improved.

[0029] Then, connect an external vacuum pump to the vacuum tube 4 and perform vacuum pumping through the external vacuum pump. When the gasket 20 is inserted into the sealing groove 19, it can play a sealing role to prevent external gas from entering between the cylinder cover 2 and the partition plate 5, enabling effective vacuum pumping between the cylinder cover 2 and the partition plate 5 to achieve the purpose of decompression. Decompressing and removing the organic solvent can reduce the boiling point of the organic solvent by reducing the environmental pressure, thereby realizing the rapid separation of the organic solvent and solving the problem proposed in the background technology.

[0030] Finally, after the separation work is completed, rotate the threaded cap 13 in the reverse direction to separate the threaded cap 13 from the threaded cylinder 12. The multiple push rods 9 are not subjected to the thrust of the pressing caps 10, and the elastic deformation force of the multiple springs 11 can drive the chassis 7 to rise and reset. The chassis 7 drives the multiple cylinders 1 to rise, and the cylinders 1 drive the sample solvent bottles inside them to automatically pop out, facilitating the extraction of the sample.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
