Description

Technical Field

[0001] The present application relates to the technical field of waste liquid treatment of mass spectrometers, and in particular to a mass spectrometer infusion pump and a waste liquid collection device thereof. Background Art

[0002] At present, the waste liquid of the mass spectrometer is the waste liquid generated during the operation of the mass spectrometer. The waste liquid generally contains certain impurities. This is because during the application period, the sample of the mass spectrometer itself is not fully purified and contains impurities. During the analysis, the impurities will enter the waste liquid. At the same time, the wear and corrosion of the internal parts of the instrument will produce tiny particles mixed in it. The purity of the reagents used is insufficient, and trace amounts of other substances will eventually exist in the waste liquid. For this reason, it is necessary to filter the waste liquid of the mass spectrometer. This is because filtration can remove solid impurities, avoid clogging subsequent pipelines and processing equipment, reduce potential harm to the environment, and reduce the interference of impurities on the subsequent treatment or recycling of the waste liquid, thereby improving the treatment efficiency and effect. Stirring during the storage of the waste liquid is to prevent precipitation and stratification of impurities, maintain the uniformity of the waste liquid components, and avoid excessive or low local concentrations, thereby providing more stable and consistent conditions for subsequent treatment; Through searching, a Chinese patent with a Chinese patent announcement number of "CN211825868U" discloses a mass spectrometer waste liquid collection device, which includes a device body, an upper cover, a bucket and a filter. The bottom of the device body is fixedly installed with a lower cover, the bottom of the lower cover is fixedly installed with a bucket, the bottom of the bucket is fixedly installed with a drain pipe, the drain pipe is fixedly installed with a micro water pump, the other end of the drain pipe is fixedly connected with a filter, the bottom of the filter is fixedly opened with a liquid outlet, the connection between the inside of the filter and the liquid outlet is fixedly installed with an interception net, and fixed blocks are fixedly installed on both sides of the interception net. The utility model is connected to the mass spectrometer through the waste liquid inlet pipe and the liquid collecting bin when the device is in use, the waste liquid is introduced into the liquid collecting bin through the waste liquid inlet pipe, the waste liquid is collected through the liquid collecting bin, and the gas is discharged to the outside through the top air pipe to avoid excessive internal pressure, so that the waste liquid can be effectively collected when the device is in use; With respect to the above-mentioned related technologies, the inventors found the following defects: During the application of the above device, the bottom of the device body is very firmly installed with a lower cover, and a bucket is firmly set at the bottom of the lower cover. The bottom of the bucket is accurately fixed with a drain pipe, and a micro water pump is firmly and properly installed on the drain pipe. The other end of the drain pipe is firmly connected to the filter. The bottom of the filter is carefully designed, and a liquid outlet is specially fixed. At the connection between the inside of the filter and the liquid outlet, an interception net is accurately fixed, and fixing blocks are tightly fixed on both sides of the interception net. In actual use, the device successfully overcomes the difficult problem that the existing equipment cannot exhaust. However, this device has significant shortcomings, specifically the inability to clean the inner wall of the collection device. This defect makes it difficult to effectively recycle the waste liquid generated by different ions. Since this cannot be done, the practicality of the device is greatly reduced. Moreover, throughout its entire use process, there is an overall lack of internal stirring structure. During storage, because there is no such stirring structure, the waste liquid will quickly precipitate, and there is a great possibility of crystallization. The occurrence of this situation will seriously affect the subsequent treatment of the waste liquid, bring many obstacles to the treatment process, and cause inconvenience that cannot be ignored.

[0023] The implementation principle of a mass spectrometer infusion pump and its waste liquid collection device in an embodiment of the present application is as follows: during the use of the device, by setting up an infusion pump body 2, in actual use, it can be connected to the mass spectrometer waste liquid discharge pipe with the help of a connecting flange 13 at the liquid inlet pipe 9. When the infusion pump body starts running, the waste liquid can be extracted and transported to the inside of the liquid storage tank 15. During this process, the activated carbon filter element 5 inside the filter box 4 plays an important role. It can assist in filtering the solution. Since the solution flows from bottom to top to the output end of the infusion pump body 2, and then is transported to the inside of the liquid storage tank 15 through a hose, the impurities in the solution will be effectively filtered by the activated carbon filter element 5 during this flow process. The impurities will be precipitated at the inner bottom of the filter box 4, and when the solution penetrates the activated carbon filter element 5, it can pass through The activated carbon filter element 5 is purified, thereby achieving a good filtering and purification effect on the solution. At this time, the filtered impurities will gather in the interior of the collecting bucket 10. When the filter box 4 needs to be maintained and cleaned, it is only necessary to loosen the adjusting bolt 8 to remove the sealing plate 6. When the sealing plate 6 is removed, the activated carbon filter element 5 can also be disassembled at the same time for replacement or cleaning. During this period, the sealing cover 12 can also be twisted to open the bottom of the collecting bucket 10, so as to collect and process the remaining filtered waste liquid containing large particles of impurities. It can be seen that the device can effectively prevent large particles of impurities from entering the interior of the infusion pump body 2, and prevent the interior of the infusion pump body 2 from being adversely affected by the attached impurities and its service life. It can be seen that the infusion pump body 2 of the device has excellent performance. By configuring the waste liquid collection device, the device can rely on the liquid storage tank 15 to assist in collecting the waste liquid transported by the infusion pump body 2 during use. After the waste liquid is stored in the liquid storage tank 15, the second motor 181 is started to run, and the second motor 181 can drive the upper rotating shaft 1821 to rotate. During this period, through the mutual linkage of the guide plate 1828 and the guide plate 1822, when the guide plate 1828 and the guide plate 1822 contact each other and the positions are staggered, the telescopic spring 1825 will reset and contract, thereby driving the entire stirring member 1829 to move upward, and when the guides of the guide plate 1822 and the guide plate 1828 are opposed to each other, the telescopic spring 1825 can be stretched, thereby prompting the entire stirring member 1829 to move downward. During this process, the stirring member 1829 is not only in a rotating state, but also in a stable and regular up and down activity state. The vertical plate 18291 is in a state, and the up and down movement of the vertical plate 18291 can drive the horizontal scraper plate 18292 and the stirring plate 18294 to move up and down. The horizontal scraper plate 18292 is arranged horizontally, and the stirring plate 18294 is cross-shaped. They can both beat the solution, causing the solution to be violently stirred and tumbled up and down, and during the rotation process, the vertical scraper plate 18293 and the stirring plate 18294 arranged in a cross shape can play a good stirring role. It can be seen that during the use of the device, the solution can be stirred up and down more evenly, which can significantly improve the stirring uniformity inside the device and avoid the situation where the stirring is uneven due to the generation of eddy currents. During the stirring process, the sliding cooperation setting of the slide bar 1827 and the side rail 1823 can cause the telescopic spring 1825 and the stirring member 1829 to be able to stably telescope and move, so that the stirring has excellent stability. At the same time, a lower stirring component 183 is provided in the stirring mechanism 18, so that during the rotation of the upper shaft 1821, the upper shaft 1821 can drive the lower shaft 1831 to rotate, and the rotation of the lower shaft 1831 can drive the auger 1832 to rotate. During the stirring process, the forward driving auger 1832 can cause the solution to roll upward, and it cooperates with the upper stirring component 182 to enhance the overall stirring and mixing effect. When the solution needs to be discharged, the auger 1832 is driven in the reverse direction, and the auger 1832 can be used as a driving force to drive the solution downward to gush out of the discharge valve 19. At the same time, the longitudinal scraper 18293, the transverse scraper 18292 and the bending scraper 1833 can be arranged to fit closely to the inner wall of the liquid storage tank 15, so that when cleaning, the auger 1832 can be easily removed. When cleaning, it can perform stable stirring and scraping, which can improve the convenience of overall subsequent cleaning and facilitate quick scraping of the solution inside the liquid storage tank 15. Moreover, when further cleaning and maintenance are needed, it is only necessary to start the first motor 166 to drive the screw rod 163 to rotate. Since the screw rod 163 and the slide rod 164 are threadedly connected, the slide rod 164 slides inside the slide frame. The power provided by the screw rod 163 can drive the slide rod 164 to slide upward. The upward movement of the slide rod 164 can pull the connecting frame 165, so that the top cover 17 is separated from the top of the liquid storage tank 15. At this time, the entire stirring mechanism 18 can be pulled out from the inside of the liquid storage tank 15, so that the device as a whole can be quickly inspected, cleaned and maintained, which can further improve the overall convenience of use of the device.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
