Description

Technical Field

[0001] This application relates to the technical field of microbial enrichment, and in particular to a microbial enrichment device. Background Technology

[0002] Airborne microorganisms are tiny microorganisms that live in the air and are invisible to the naked eye. Many important infectious diseases in humans can be transmitted through the air. Studies have shown that the prevalence of hospital-acquired infections is 3% to 20%, of which respiratory infections caused by airborne microorganisms account for about 15% to 20%. Due to the high hazard of airborne microorganisms, monitoring airborne microorganisms under various environmental conditions is of great significance.

[0003] There are various ways to enrich airborne microorganisms, such as liquid filtration, filter retention, and electrostatic deposition. Among them, filter retention mainly uses an air extraction device to allow air to pass through the filter material, while microbial particles are trapped on the filter material, which has the characteristic of high enrichment efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: after retaining biological particles on a filter screen using filtration methods, the filter screen needs to be disassembled and then immersed in a solution to allow the biological particles to enter the solution, which is a cumbersome operation. Therefore, we propose a microbial enrichment device. Utility Model Content

[0009] A flipping mechanism is installed on the enrichment tank and connected to the flipping frame. The flipping mechanism is used to drive the flipping frame to flip 180 degrees, thereby causing the filter screen to rotate 180 degrees.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a microbial enrichment device. For example... Figures 1-3 As shown, it includes an enrichment tank 1, a support leg 29 fixedly connected to the bottom end of the enrichment tank 1, a cover 2 fixedly connected to the top end of the enrichment tank 1, a discharge pipe 3 connected to the bottom end of the enrichment tank 1, a valve 28 installed on the discharge pipe 3, a tilting frame 4 installed inside the enrichment tank 1, a filter screen 5 fixedly connected to the tilting frame 4, and an air suction fan 6 installed inside the cover 2.

[0028] Also includes:

[0029] The flipping mechanism 7 is installed on the enrichment tank 1 and connected to the flipping frame 4. The flipping mechanism 7 is used to drive the flipping frame 4 to flip 180 degrees, thereby causing the filter screen 5 to rotate 180 degrees.

[0030] The rinsing mechanism 8 includes a rinsing component 9 and a rotating component 10. The rinsing component 9 is used to rinse the flipped filter screen 5, and the rotating component 10 is used to drive the rinsing component 9 to rotate, so that the rinsing component 9 rinses the filter screen 5 evenly. The flipping mechanism 7 flips the filter screen 5 180 degrees, so that the microorganisms enriched on the filter screen 5 face the inside of the enrichment tank 1, and then the rinsing mechanism 8 washes the microorganisms into the enrichment tank 1.

[0031] Please see Figure 3 and Figure 4 The flipping mechanism 7 shown in the figure includes a rotating shaft 11 fixedly connected to the flipping frame 4. The rotating shaft 11 is rotatably connected to the enrichment tank 1, and a spur gear 12 is fixedly connected to the end of the rotating shaft 11. A rack 13 meshes with the outer side of the spur gear 12. A moving component 14 for driving the rack 13 to move is connected to the rack 13. Through the cooperation of the rack 13 and the spur gear 12, the rotating shaft 11 can drive the filter screen 5 to flip 180 degrees, and the moving component 14 can position the flipped filter screen 5.

[0032] Please see Figure 3 and Figure 4 The movable component 14 shown in the figure includes a fixed base 15 fixedly connected to the enrichment tank 1. A telescopic rod 16 is fixedly connected to the fixed base 15. A connecting rod 17 is fixedly connected to the end of the telescopic rod 16. A fixed block 18 fixedly connected to the rack 13 is fixedly connected to the end of the connecting rod 17. The rack 13 moves by moving the telescopic rod 16. After the telescopic rod 16 stops moving, the position of the rack 13 will be fixed, so that the filter screen 5 is stationary after flipping.

[0033] Please see Figure 3 and Figure 5 The flushing assembly 9 shown in the figure includes a diversion pipe 19 installed inside the enrichment tank 1. The diversion pipe 19 is installed at the top of the filter screen 5, and multiple sets of flushing pipes 20 are connected to the diversion pipe 19. Multiple sets of nozzles 21 are connected to the flushing pipes 20. The diversion pipe 19 is connected to the rotating assembly 10, and a liquid inlet 22 is also connected to the diversion pipe 19. The multiple sets of nozzles 21 facilitate the flushing of microorganisms on the filter screen 5.

[0034] Please see Figure 3 and Figure 5 The liquid inlet 22 shown in the figure includes a sealing cap 23 rotatably connected to the diversion pipe 19. A liquid inlet pipe 24 is connected to the sealing cap 23. The liquid inlet pipe 24 extends to the outside of the enrichment tank 1. The flushing solution is delivered through the liquid inlet pipe 24. The sealing cap 23 is rotatably connected to the diversion pipe 19, so as not to affect the rotation of the diversion pipe 19.

[0035] Please see Figure 3 and Figure 5The rotating assembly 10 shown in the figure includes a fixed frame 25 fixed inside the enrichment tank 1. A motor 26 is fixedly connected to the fixed frame 25. A drive shaft 27 is fixedly connected to the output end of the motor 26. The drive shaft 27 is fixedly connected to the diversion pipe 19 and rotatably connected to the sealing cover 23. The start of the motor 26 enables the drive shaft 27 to drive the diversion pipe 19 to rotate, thereby enabling the flushing pipe 20 to flush the filter screen 5 in all directions.

[0036] The implementation principle of the microbial enrichment device in this application embodiment is as follows: When enriching microorganisms in the air, the suction fan 6 is activated, and the suction fan 6 draws all the air and microorganisms into the enrichment tank 1. The air is completely discharged through the filter screen 5, while the microorganisms are all trapped on the filter screen 5. After enrichment for a period of time, the telescopic rod 16 is activated, causing the connecting rod 17 to extend. The movement of the connecting rod 17 causes the rack 13 to move, which in turn causes the spur gear 12 to rotate, thereby causing the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the tilting frame 4 to rotate, which in turn causes the filter screen 5 to rotate. After reaching 80 degrees, the telescopic rod 16 stops operating. At this time, due to the flipping of the filter screen 5, the microorganisms on the filter screen 5 face the bottom of the enrichment tank 1. Then, through the action of the liquid inlet pipe 24, the corresponding solution is delivered into the diversion pipe 19. After that, the solution will enter the multiple sets of flushing pipes 20 through the diversion pipe 19, and then be sprayed onto the filter screen 5 through the nozzle 21. Through the flushing action, all the microorganisms enriched on the filter screen 5 are flushed into the enrichment tank 1. At the same time, the motor 26 is started, causing the drive shaft 27 to rotate. The rotation of the drive shaft 27 causes the diversion pipe 19 to rotate, and then the action of the diversion pipe 19 causes the flushing pipe 20 and the nozzle 21 to rotate, thus facilitating the flushing of the entire filter screen 5. After the flushing is completed, the suction fan 6 is started again to enrich the microorganisms.

[0037] 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.
