Description

Technical Field

[0001] The present invention relates to the technical field of virus detection in water bodies, and specifically to a rapid enrichment and concentration pretreatment device for viruses in water bodies. Background Technique

[0002] Compared with clinical samples, the content of viruses in environmental water bodies is low, and there are a large number of impurities at the same time. Therefore, virus determination cannot be directly carried out and enrichment and concentration are required. Currently reported methods for enriching and concentrating viruses in water include the charge membrane method, centrifugal ultrafiltration method, polyethylene glycol precipitation method, and coagulation adsorption method. Among them, the coagulation precipitation method uses the aluminum hydroxide colloid generated by the hydrolysis of aluminum salts to adsorb viruses, and transfers them from water to the precipitate as the aluminum hydroxide colloid settles. The enrichment and concentration of viruses in water can be achieved by removing the aqueous solution through centrifugation or filtration. Compared with methods such as the charge membrane method, centrifugal ultrafiltration method, and polyethylene glycol precipitation method, the coagulation precipitation method has the advantages of simple operation, rapidity, and low cost.

[0003] Therefore, we have proposed a rapid enrichment and automated pretreatment device for viruses in water bodies based on the aluminum salt coagulation precipitation method to facilitate the solution of the problems raised above. Summary of the Invention

A fixing plate 30 is bolted and fixed on the side of the base 29. A fifth motor 32 is bolted and fixed inside the bottom of the base 29. A second infusion tube 31 is fixed on the rear inner wall of the enrichment machine 5. A heating sheet 36 is fixed on the inner wall of the enrichment machine 5. The output ends of the second motor 16, the third motor 17, the fourth motor 18 and the fifth motor 32 are all bolted and fixed with threaded rods 33. A diaphragm pump 34 and a metering pump 35 are bolted and fixed inside the control machine 1;

[0030] The linkage rod 11 and the turntable 10 form a rotating structure. A chute 12 is provided inside the linkage rod 11, and the chute 12 and the column 8 form a limiting sliding structure. At the same time, the pH meter 13 connected to the outside of the linkage rod 11 is perpendicular to the flocculation tank 15. By controlling the rotation of the turntable 10, the linkage rod 11 can drive the pH meter 13 to fully stir the water body inside the flocculation tank 15, so that the water body can quickly react with the flocculant and the pH adjustment agent, and the viruses in the water body can be quickly flocculated;

[0031] The first infusion pipes 14 are symmetrically distributed with respect to the pH meter 13, and the positions of the first infusion pipes 14 and the filtration tank 20 correspond up and down. Through this structure, the ends of the first infusion pipes 14 can move synchronously with the linkage rod 11, so that the first infusion pipes 14 can evenly add the reagent into the flocculation tank 15, thereby further promoting the mixing and reaction efficiency of the water body and the reagent;

[0032] A drain pipe 1502 is connected to the lower end of the flocculation tank 15, and a pinch valve 1501 is installed outside the drain pipe 1502. Through the pinch valve 1501, the discharge of the water body in the flocculation tank 15 can be controlled, so that the reagent inside the flocculation tank 15 can fully react;

[0033] The air blowing nozzle 19 corresponds to the position of the filtration tank 20, and the air blowing nozzle 19 has a funnel-shaped structure. The left end of the air blowing nozzle 19 is threadedly connected to the threaded rod 33 connected to the output end of the fourth motor 18. At the same time, the air blowing nozzle 19 and the enrichment machine 5 form a lifting structure. By rotating the threaded rod 33, the air blowing nozzle 19 can be driven to lift, so that the air blowing nozzle 19 can fit against the inner wall of the filtration tank 20, so that the viruses enriched in the filtration tank 20 can be blown and collected;

[0034] The enrichment scraper 21 fits against the inner wall of the filtration tank 20, and the cross-section of the filtration tank 20 is funnel-shaped or "V"-shaped. The positions of the filtration tank 20 and the flocculation tank 15 correspond up and down. At the same time, the movable plate 22 bolted below the enrichment scraper 21 is threadedly connected to the threaded rod 33 connected to the output end of the second motor 16. By rotating the threaded rod 33, the movable plate 22 and the enrichment scraper 21 can be driven to move synchronously for adjustment, so that the enrichment scraper 21 can scrape and converge the flocs remaining after filtration inside the filtration tank 20, facilitating subsequent collection and treatment;

[0035] The upper layer of the filter paper carrier plate 23 is a porous aluminum plate structure, and the lower layer of the filter paper carrier plate 23 is a plastic structure. The filter paper carrier plate 23 corresponds to the position of the filter tank 20 up and down. At the same time, a fixing block 2301 is bolted to the lower surface of the filter paper carrier plate 23. Moreover, the inner part of the lower layer of the filter paper carrier plate 23 is in a funnel-shaped structure, and a sewage pipe 2302 is connected to the rear side of the filter paper carrier plate 23. And the fixing block 2301 is threadedly connected to the threaded rod 33 connected to the output end of the fifth motor 32. By rotating the threaded rod 33, the position of the filter paper carrier plate 23 can be adjusted, so that the flocculation filter paper 24 on the surface of the filter paper carrier plate 23 can fit against the bottom of the filter tank 20 and move, avoiding blockage caused by the sample water body being filtered at a single place of the flocculation filter paper 24, and effectively improving the filtering effect of the device;

[0036] A test tube 27 is sleeved outside the socket seat 25, and through holes 26 are provided inside both the test tube 27 and the filter paper carrier plate 23. And the through holes 26 correspond to the lower end position of the filter tank 20. At the same time, the test tube 27 corresponds to the lower end position of the second infusion tube 31. Through this structure, the viruses enriched by the device can effectively enter the test tube 27 through the action of wind for collection, facilitating subsequent sampling of viruses in the water body and improving the operation convenience of the device;

[0037] The fixing plate 30 connected to the outside of the base 29 forms a lifting structure with the enrichment machine 5 through the slide rail 6. The base 29 and the filter paper carrier plate 23 form a sliding structure. And the fixing plate 30 is threadedly connected to the threaded rod 33 connected to the output end of the third motor 17. By controlling the rotation of the threaded rod 33, the fixing plate 30 can drive the base 29 and the filter paper carrier plate 23 to be adjusted up and down along the slide rail 6, so that the filter paper carrier plate 23 can be closely attached to the lower end of the filter tank 20, thereby realizing the filtration of the flocculating liquid.

[0038] Working principle: When using this rapid enrichment pretreatment equipment for viruses in water, first, as Figure 1-5As shown, power on the device, and then control the fifth motor 32 to drive the threaded rod 33 to rotate, so that the fixing block 2301 outside the threaded rod 33 drives the filter paper carrier plate 23 to move out of the bin. Select a filter paper carrier plate 23 with a suitable porous aluminum structure according to the amount of the sample to be pretreated. Then fix and lay the flocculation filter paper 24 on the upper surface of the filter paper carrier plate 23. Then control the third motor 17 to drive the fixing plate 30 to move the base 29 upward along the slide rail 6, so that the upper surface of the filter paper carrier plate 23 can fit against the lower end of the filtration tank 20. Then the metering pump 35 introduces the water body to be treated into the flocculation tank 15. Then control the metering pump 35 to add the flocculant in the reagent tank 4 into the flocculation tank 15 through the first infusion tube 14. At the same time, start the first motor 9, so that the first motor 9 drives the turntable 10 to rotate at a constant speed. At this time, the turntable 10 will drive the linkage rod 11 to move synchronously. At this time, the linkage rod 11 slides along the chute 12, so that the linkage rod 11 can drive the pH meter 13 and the first infusion tube 14 to move synchronously. At this time, the first infusion tube 14 can evenly add the reagent into the flocculation tank 15. At the same time, the pH meter 13 can fully stir the water body and the flocculant, making the flocculation effect of the device better and effectively improving the flocculation rate of the device. After the flocculation is completed, control the metering pump 35 to add a pH regulator into the flocculation tank 15 according to the specific pH value of the water body, and at the same time control the pH meter 13 to stir the water body again, so that the pH value of the water body is maintained at 6;

[0039] As Figure 1-2 and Figure 6-8As shown, the control pinch valve 1501 opens the liquid discharge pipe 1502, so that the water in the flocculation tank 15 is discharged into the filtration tank 20 through the liquid discharge pipe 1502. At the same time, the metering pump 35 is controlled to suck the cleaning water and discharge it into the flocculation tank 15 through the first infusion pipe 14, so that the flocs inside the flocculation tank 15 are fully discharged into the filtration tank 20. After standing for a period of time, the flocs are fully settled in the filtration tank 20. Then, the fifth motor 32 is controlled to drive the threaded rod 33 at its end to rotate in the reverse direction, so that the filter paper carrier plate 23 gradually returns to the warehouse. At this time, the flocculation filter paper 24 will move along the lower surface of the filtration tank 20, so that the flocculation liquid inside the filtration tank 20 will flow to the flocculation filter paper 24, and thus move and filter on the surface of the flocculation filter paper 24, avoiding the flocculation blocking the flocculation filter paper 24 and reducing the filtration efficiency. After the filtration is completed, the lower end of the filtration tank 20 corresponds to the through hole 26 up and down. Then, the second motor 16 is controlled to drive the threaded rod 33 connected to its end, so that the threaded rod 33 drives the enrichment scraper 21 and the movable plate 22 to slide and adjust along the inner wall of the filtration tank 20, so that the enrichment scraper 21 can scrape the flocs remaining on the inner wall of the filtration tank 20 to one side. At this time, part of the flocs will automatically fall into the middle of the test tube 27 through the through hole 26 for collection to achieve the enrichment purpose. Then, the fourth motor 18 is controlled to drive the threaded rod 33 connected to its end to rotate, so that the air blowing nozzle 19 threadedly connected to the outside of the threaded rod 33 moves downward, so that the air blowing nozzle 19 is located between the filtration tank 20 and the enrichment scraper 21. Then, the air blowing nozzle 19 is controlled to blow air into the filtration tank 20, so that the remaining flocs inside the filtration tank 20 can fully fall into the test tube 27 for collection. Then, the fifth motor 32 is continuously controlled to drive the threaded rod 33 at its end to rotate. At this time, the filter paper carrier plate 23 will continue to move backward, so that the position of the test tube 27 corresponds to the second infusion pipe 31 up and down. Then, the metering pump 35 is controlled to add PBS solution to the test tube 27 through the second infusion pipe 31. Then, the fifth motor 32 is controlled to drive the threaded rod 33 at its end to rotate in the forward direction, so that the filter paper carrier plate 23 moves outward and returns to the starting position of the used filter paper.After the pretreatment of a single water sample is completed, control the diaphragm pump 34 to add sodium hypochlorite into the flocculation tank 15 through the first infusion tube 14. After standing for an appropriate time, then drain the sodium hypochlorite into the filtration tank 20. After standing for an appropriate time, finally control the movement of the filter paper carrier plate 23 so that the sodium hypochlorite can effectively disinfect the used filter paper and the filter paper carrier plate at the corresponding position. Then control the diaphragm pump 34 to pump water successively through the flocculation tank 15, the filtration tank 20 and the filter paper carrier plate 23. The steps are the same as those of the sodium hypochlorite addition step. During this process, the heating sheet 36 can heat the water, thereby completing the thorough cleaning of the device. At this time, if the device is set for batch pretreatment, the filter paper carrier plate will move to the position of the next clean filter paper and fit again with the bottom of the filtration tank. The metering pump works to collect and introduce the next sample until the pretreatment of all water samples is completed. At this time, the staff can take out the test tube 27 placed on the bracket 28, thus completing the enrichment pretreatment of the virus in the water body.
