Description

Technical Field

[0001] This application relates to the field of mass spectrometer waste liquid treatment technology, and in particular to a mass spectrometer infusion pump and its waste liquid collection device. Background Technology

[0002] Currently, mass spectrometer waste liquid refers to the waste liquid generated during the operation of the mass spectrometer. This waste liquid generally contains certain impurities. This is because the mass spectrometer sample itself may not be fully purified during application and may contain impurities. During analysis, these impurities enter the waste liquid. Additionally, wear and corrosion of internal instrument components can cause tiny particles to mix in. Furthermore, insufficient purity of the reagents used may result in trace amounts of other substances that ultimately remain in the waste liquid. Therefore, it is necessary to filter the mass spectrometer waste liquid. Filtration removes solid impurities, preventing blockage of subsequent pipelines and processing equipment, reducing potential environmental hazards, and minimizing interference from impurities in subsequent treatment or recycling, thereby improving processing efficiency and effectiveness. Stirring the waste liquid during storage prevents impurities from settling and stratifying, maintains the homogeneity of the waste liquid composition, and avoids excessively high or low local concentrations, thus providing more stable and consistent conditions for subsequent processing.

[0003] A search revealed a Chinese patent with publication number "CN211825868U" that discloses a waste liquid collection device for a mass spectrometer. The device includes a main body, an upper cover, a trough, and a filter. A lower cover is fixedly installed at the bottom of the main body, and a trough is fixedly installed at the bottom of the lower cover. A drain pipe is fixedly installed at the bottom of the trough, and a miniature water pump is fixedly installed on the drain pipe. A filter is fixedly connected to the other end of the drain pipe, and an outlet is fixedly opened at the bottom of the filter. An intercepting net is fixedly installed at the connection between the filter and the outlet, and fixing blocks are fixedly installed on both sides of the intercepting net. This invention, through its waste liquid inlet pipe and collection chamber, allows the mass spectrometer to be connected via the waste liquid inlet pipe during use. The waste liquid is then introduced into the collection chamber, where it is collected. Gas is discharged to the outside through a top gas pipe to prevent excessive internal pressure, thus enabling effective waste liquid collection during device use.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0005] In the application of the aforementioned device, a bottom cover is securely installed on the bottom of the main body of the device. A trough is firmly positioned at the bottom of the bottom cover, and a drain pipe is precisely fixed to the bottom of the trough. A miniature water pump is securely mounted on the drain pipe, and the other end of the drain pipe is firmly connected to a filter. The bottom of the filter is carefully designed with a specially fixed outlet. An intercepting net is precisely fixed at the connection point between the filter and the outlet, and fixing blocks are also tightly fixed on both sides of the intercepting net. This device successfully overcomes the difficult problem of existing equipment being unable to exhaust air in practical applications. However, this device has significant shortcomings. Specifically, it cannot clean the inner wall of the collection device, making it difficult to effectively recycle waste liquid generated by different ions. This significantly reduces the device's practicality. Furthermore, it lacks an internal stirring structure throughout its operation. During storage, without such a stirring structure, the waste liquid will quickly settle and is highly likely to crystallize. This will seriously affect subsequent waste liquid treatment, creating numerous obstacles and causing considerable inconvenience to the process. Summary of the Invention

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. The infusion pump body is connected to the mass spectrometer waste liquid discharge pipe through the inlet pipe flange. During operation, the waste liquid is drawn into the storage tank. The activated carbon filter element in the filter box assists in filtration. The solution flows from bottom to top, and impurities are filtered and precipitated at the bottom of the tank. The solution is purified when it passes through. The filtered impurities are collected in the collection hopper. During maintenance and cleaning, the sealing plate and activated carbon filter element can be removed by loosening the adjusting bolts.

This device can prevent large particles of impurities from entering the infusion pump body and prevent it from affecting its service life. The infusion pump body has excellent performance.

[0019] 2. By configuring a waste liquid collection device, this device relies on a storage tank to collect the waste liquid delivered by the infusion pump during application. After the waste liquid is stored, the second motor is started to drive the upper rotating shaft to rotate. During this process, the guide plate and the guide plate are linked together. When the positions are misaligned, the telescopic spring contracts and drives the agitator to move upward. When the guide plates are opposite, the spring extends and causes the agitator to move downward. The agitator not only rotates but also moves up and down regularly, driving the horizontal scraper and the cross-shaped agitator to beat the solution, causing vigorous stirring and rolling. The longitudinal scraper and the cross-shaped agitator also play a good stirring role, which can evenly stir and avoid eddies and unevenness. The slider and the side rail cooperate to make the stirring stable.

[0020] 3. The lower stirring component of the stirring mechanism is used. The rotation of the upper shaft drives the lower shaft and the auger to rotate. During stirring, the forward drive causes the solution to roll upward, which, together with the upper stirring component, improves the mixing effect. When discharging the solution, the reverse drive causes the solution to gush out from the drain valve. The longitudinal scraper, transverse scraper, and bent scraper can adhere to the inner wall of the storage tank. During cleaning, they stir and scrape, improving the convenience of subsequent cleaning. When cleaning and maintenance are required, the first motor is started to drive the lead screw, which moves the slide bar upward to pull out the stirring mechanism, enabling quick inspection, cleaning, and maintenance, and improving the ease of use.

The operation is convenient and facilitates the maintenance and adjustment of the internal components. The second motor 181 of the stirring mechanism 18 drives the upper stirring assembly 182 and the lower stirring assembly 183 to achieve comprehensive and thorough stirring, so that the waste liquid is mixed evenly, improving the treatment effect and efficiency. This design makes the device have good performance in operation and maintenance, enhancing the practicality and reliability of the device.

[0036] Please refer to Figures 3-7The upper stirring assembly 182 includes an upper rotating shaft 1821 and a guide plate 1822. The upper rotating shaft 1821 is fixedly installed at the bottom output end of the second motor 181. Side rails 1823 are fixedly installed at equal intervals on the outer side of the upper rotating shaft 1821. The guide plate 1822 is fixedly installed at equal intervals on the bottom of the top cover 17. A top plate 1824 is fixedly installed at the upper outer end of the side rails 1823. Telescopic springs 1825 are fixedly installed at equal intervals on the bottom of the top plate 1824. A base plate 1826 is fixedly installed on the bottom of the telescopic springs 1825. A slide bar 1827 is fixedly installed on the inner end of the base plate 1826. The slide bar 1827 is slidably connected to the inside of the side rails 1823. A guide plate 1828 is fixedly installed on the outer side of the base plate 1826. The top of guide plate 1828 and the bottom of guide plate 1822 are fitted together. An agitator 1829 is fixedly installed at the bottom of guide plate 1828. Both guide plate 1828 and guide plate 1822 are shaped as isosceles triangles. The agitator 1829 includes a vertical plate 18291. Horizontal scrapers 18292 and longitudinal scrapers 18293 are fixedly installed at equal intervals on the outer side of vertical plate 18291. The horizontal scrapers 18292 and longitudinal scrapers 18293 are arranged sequentially at equal intervals on the outer side of vertical plate 18291. An agitator 18294 is fixedly installed on the inner side of vertical plate 18291. The agitator 18294 has a cross-shaped cross section.

The horizontal scraper 18292 and vertical scraper 18293 on the outer side of the vertical plate 18291 and the cross-shaped agitator 18294 on the inner side can fully agitate the waste liquid and make it evenly mixed. The lower rotating shaft 1831 of the lower agitator 183 drives the auger 1832 to rotate and agitate the waste liquid. At the same time, the bent scraper 1833 can scrape against the bottom of the storage tank 15 to prevent impurities from settling. The conical design of the storage tank 15 and the auger 1832 is conducive to liquid flow and agitation. This upper and lower coordinated agitator design greatly improves the agitation effect and efficiency, ensuring the quality and progress of waste liquid treatment.

[0037] The implementation principle of the mass spectrometer infusion pump and its waste liquid collection device in this application embodiment is as follows: During the period of use, the device is equipped with an infusion pump body 2. In actual use, it can be connected to the mass spectrometer waste liquid discharge pipe via the connecting flange 13 at the inlet pipe 9. When the infusion pump body is started, the waste liquid can be drawn and transported to the inside of the storage tank 15. In 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 storage tank 15 through the hose, impurities in the solution will be effectively filtered by the activated carbon filter element 5 during this flow process. The impurities will settle at the bottom of the filter box 4, and when the solution passes through the activated carbon filter element 5, it can pass through... The activated carbon filter element 5 effectively purifies the solution, achieving a good filtration and purification effect. The filtered impurities collect inside the collection hopper 10. When maintenance and cleaning of the filter box 4 are required, simply loosen the adjusting bolt 8 to remove the sealing plate 6. Removing the sealing plate 6 also allows for the disassembly of the activated carbon filter element 5 for replacement or cleaning. During this process, the sealing cover 12 can be twisted to open the bottom of the collection hopper 10, allowing for the collection and treatment of the remaining filtered waste liquid containing large particulate impurities. Therefore, this device effectively prevents large particulate impurities from entering the infusion pump body 2, preventing impurities from adversely affecting its service life. This demonstrates the excellent performance of the infusion pump body 2 in this device.

[0038] By configuring a waste liquid collection device, this device can collect the waste liquid delivered by the infusion pump body 2 with the assistance of the storage tank 15 during application. After the waste liquid is stored in the storage tank 15, the second motor 181 is started. 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 are in contact and misaligned, the telescopic spring 1825 will return to its original position and contract, thereby driving the entire agitator 1829 to move upward. When the guide plates 1822 and 1828 are opposite to each other, the telescopic spring 1825 can be extended, thereby causing the entire agitator 1829 to move downward. During this process, the agitator 1829 is not only in a rotating state, but also in a stable and regular up-and-down movement state. In this device, the vertical movement of the vertical plate 18291 drives the horizontal scraper 18292 and the stirring plate 18294 to move up and down. The horizontal scraper 18292 is horizontally positioned, while the stirring plate 18294 is cross-shaped. Both can slap the solution, causing it to violently agitate and tumble. Furthermore, during rotation, the vertical scraper 18293 and the cross-shaped stirring plate 18294 also provide excellent stirring. Therefore, this device can promote relatively uniform vertical mixing of the solution during use, significantly improving the internal agitation uniformity and preventing eddies that could lead to uneven agitation. During agitation, the sliding engagement of the slider 1827 and the side rail 1823 allows the telescopic spring 1825 and the stirring element 1829 to move stably, ensuring excellent agitation stability.

[0039] Meanwhile, the lower stirring component 183 in the stirring mechanism 18 allows the upper rotating shaft 1821 to drive the lower rotating shaft 1831 to rotate during the rotation of the upper rotating shaft 1821. The rotation of the lower rotating shaft 1831 drives the auger 1832 to rotate. During the stirring process, the forward-driven auger 1832 causes the solution to tumble upwards. Its cooperation with the upper stirring component 182 enhances the overall mixing effect. When it is necessary to drain the solution, the reverse-driven auger 1832 provides the driving force to push the solution downwards to the drain valve 19. Furthermore, the longitudinal scraper 18293, transverse scraper 18292, and bent scraper 1833 are designed to fit tightly against the inner wall of the storage tank 15, facilitating cleaning. During cleaning, the device can perform stable agitation and scraping, improving the convenience of subsequent cleaning. It facilitates the quick removal of the solution inside the storage tank 15. Furthermore, when further cleaning and maintenance are required, simply start the first motor 166 to drive the lead screw 163 to rotate. Since the lead screw 163 and the slide rod 164 are threadedly connected, the slide rod 164 slides inside the slide frame. Power provided by the lead screw 163 can drive the slide rod 164 to slide upward. The upward movement of the slide rod 164 can pull out the connecting frame 165, causing the top cover 17 to detach from the top of the storage tank 15. At this time, the entire stirring mechanism 18 can be pulled out from the inside of the storage tank 15, enabling the device to be quickly inspected, cleaned, and maintained, further improving the overall ease of use of the device.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
