Description

Technical Field

[0001] The utility model belongs to the technical field of PCR plate purification, in particular to an air purification device for PCR plate conveying equipment. Background Art

[0002] PCR (polymerase chain reaction) plates are containers used in molecular biology laboratories to carry PCR reactions. They are usually made of polypropylene (PP), a material that can adapt to the high and low temperature cycles during the PCR reaction process and can withstand high temperature and high pressure sterilization.

[0003] A patent with announcement number CN 214130805 U discloses a purification device for hospital PCR laboratories, comprising: a mobile body; a cover plate, the cover plate being fixedly connected to the top of the mobile body; an air purification assembly, the air purification assembly being arranged on the top of the mobile body; and a floor cleaning assembly, the floor cleaning assembly being arranged inside the mobile body. The mobile body comprises two hydraulic lifting columns, a transverse plate being fixedly connected between the bottoms of the hydraulic lifting columns, a connecting frame being fixedly connected to both sides of the bottom of the transverse plate, and a front baffle being fixedly connected to the front side between the bottoms of the two connecting frames. The utility model provides a purification device for hospital PCR laboratories, which has good air purification effect and can clean the floor by itself after air purification is completed, without the need to replace the equipment for separate cleaning. The device has multiple functions and is easy to use, avoiding the difficulty of frequent equipment changes that increase the cleaning and disinfection work.

[0004] In the current existing technology, before the existing PCR plate is transported and collected, it is necessary to soak the PCR plate in an acidic solution (such as dilute hydrochloric acid or dilute sulfuric acid) for several minutes to half an hour to remove alkaline substances and organic residues, and then rinse it with clean water. Then, it can be soaked in an alkaline solution (such as sodium hydroxide solution) to remove acidic substances and inorganic salt residues, and then rinsed with clean water again. This method of using immersion to clean dust will leave certain water stains inside the PCR plate. When cleaning the water stains, it is necessary to use hot air flow to dry the water droplets. However, during the drying process, the flow of air will drive the dust in the outside air, and some of this dust will remain on the surface of the PCR plate, causing secondary contamination of the PCR plate.

[0005] Therefore, in order to solve the above problems, an air purification device for PCR plate conveying equipment is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 5 The utility model provides an air purification device for PCR plate conveying equipment, comprising a support frame 11 and a conveying crawler 111 arranged on the top outer surface of the support frame 11, a PCR plate clamping platform 12 detachably mounted on the top outer surface of the conveying crawler 111, an air purification box 13 detachably mounted on the bottom outer surface of the conveying crawler 111, a sealed cavity box 131 fixedly mounted on the bottom inner wall surface of the air purification box 13, blowers 132 symmetrically fixedly mounted on the inner walls of both sides of the sealed cavity box 131, an arc-shaped suction plate 135 fixedly mounted on the top and at the edge positions of both sides of the sealed cavity box 131, and air purifiers 136 symmetrically fixedly mounted on the inner walls of both sides of the air purification box 13. There is an air guide box 136 movably sleeved on the outer surface of the top of the arc-shaped air suction plate 135; the top outer surface of the air guide box 136 and the air inlet a4 are opened on the edge positions of both sides, and the top left inner wall surface of the air guide box 136 is fixedly connected to the guide plate a1 set on the bottom edge position of the air inlet a4, and the top inner wall surface of the air guide box 136 and the middle position are fixedly installed with a support column a5, and the outer surface of the support column a5 is movably sleeved with a transmission blade a6, and the outer surface of the air purification box 13 and the inner wall surface of the inner side of the air guide box 136 are movably sleeved with a transmission rod a7, and the outer surface of the transmission rod a7 and the outer surface of the two ends of the transmission blade a6 are movably sleeved with a transmission crawler a8;

[0028] During operation, the blower 132 is used to absorb gas inside the sealed cavity box 131 and the air guide box 136, and the air inlet at the top of the air guide box 136 is attached to the top outer surface of the conveyor belt 111. Under the absorption of strong wind force, the PCR board on the top surface of the conveyor belt 111 and the surrounding environment are absorbed, so that the dust on the surface of the PCR board and the surrounding area are absorbed into the interior of the air guide box 136 through the air inlet a4. The air guide box 136 is used to filter dust impurities in the air, and the filtered air will pass through the air guide box 136 and the arc-shaped suction plate 135 into the interior of the sealed cavity box 131, thereby achieving the effect of filtering the dust. The gas that passes through the air inlet a4 and enters the interior of the air guide box 136 is guided and pushed by the guide plate a1, and the airflow will hit the support column The transmission blades a6 on the outer surface of a5 push, so that the transmission blades a6 drive the transmission tracks a8 on the outer surfaces at both ends to transmit, and at the same time drive the transmission rod a7 on the outer surface of one end of the transmission tracks a8 to rotate on the inner wall surface of the bottom of the air guide box 136, so as to clean up the dust accumulated on the inner wall surface of the bottom of the air guide box 136. At the same time, under the push of wind force, the dust accumulates at the lowest point inside the air guide box 136, and the excess gas inside the air guide box 136 will be discharged from the inner walls on both sides of the air guide box 136, so as to achieve the effect of cleaning and scraping off the dust accumulated and adhered to the inner wall surface of the air guide box 136, and avoid the continuous accumulation of dust adhering to the inner wall surface of the air guide box 136, which will affect the ventilation efficiency on the surface of the air guide box 136, making it impossible for the gas to be ventilated effectively and quickly.

[0029] Further, such as Figures 1 to 5 As shown, the baffle a2 set on the bottom edge of the air inlet a4 is fixedly connected to the right inner wall of the top of the air guide box 136, and the arc-shaped guide strip a3 set on the bottom edge of the air inlet a4 is fixedly connected to the right inner wall of the air guide box 136. A ring a71 is detachably installed on the outer surface of the transmission rod a7, and a soft scraper a72 movably sleeved on the inner wall of the air guide box 136 is fixedly connected to the outer surface of the ring a71. The bottom of the air purification box 13 A purification box 134 is fixedly connected to the surface and movably sleeved on the outer surface of the guide tube 133. The interior of the purification box 134 is filled with clean water. A breathable cavity is provided in the gap between the purification box 134 and the guide tube 133. A water vapor filter pad 138 provided on the surface of the purification box 134 and the guide tube 133 is fixedly connected to the inner wall of the breathable cavity. A transmission motor 112 is provided on the top surface of the support frame 11 and at the edge of one side of the bottom end of the conveyor belt 111.

[0030] During operation, when the transmission belt a8 drives the transmission rod a7 to transmit, the soft scraper strip a72 on the outer surface of the transmission rod a7 continuously slides on the inner wall of the air guide box 136, and the rubber strip on the surface of 172 is used to clean and scrape off the adhering dust. While scraping off the dust, the arc-shaped guide strip a3 on the inner wall of the air guide box 136 is used to guide the flowing gas in an arc shape, thereby blowing off some fine dust adhering to the surface of the soft scraper strip a72; the filtered gas will accumulate inside the sealed cavity box 131 under the push of the blower 132, and pass through the guide pipe 133 into the interior of the purification box 134, and cooperate with the water source inside the purification box 134 to moisten the fine debris remaining in the air. As the gas continues to flow, it passes through the guide pipe 133, and then cooperates with the water vapor filter pad 138 to filter out the water vapor in the gas.

[0031] Working principle: The blower 132 is used to absorb gas inside the sealed cavity box 131 and the air guide box 136. The air inlet on the top of the air guide box 136 is attached to the top outer surface of the conveyor belt 111. Under the absorption of strong wind force, the PCR board on the top surface of the conveyor belt 111 and the surrounding environment are absorbed. The dust on the surface of the PCR board and the surrounding environment are absorbed into the interior of the air guide box 136 through the air inlet a4. The air guide box 136 is used to filter dust impurities in the air. The filtered air will pass through the air guide box 136 and the arc-shaped air suction plate 135 into the interior of the sealed cavity box 131, achieving the effect of filtering dust.

[0032] The air entering the air guide box 136 through the air inlet a4 is guided and pushed by the guide plate a1, and the air flow pushes the transmission blades a6 on the outer surface of the support column a5, so that the transmission blades a6 drive the transmission crawlers a8 on the outer surfaces of both ends to transmit, and at the same time drive the transmission rod a7 on the outer surface of one end of the transmission crawler a8 to rotate on the inner wall surface of the bottom of the air guide box 136, so as to clean up the dust accumulated on the inner wall surface of the bottom of the air guide box 136. When the transmission crawler a8 drives the transmission rod a7 to transmit, the soft scraper a72 on the outer surface of the transmission rod a7 continuously slides on the inner wall surface of the air guide box 136, and uses the rubber strip on the surface of 172 to clean up and scrape off the adhered dust. While scraping off the dust, the curved guide strips a3 on the inner wall surface of the air guide box 136 are used to guide the flowing air in an arc shape, thereby blowing off some fine dust adhered to the surface of the soft scraper strip a72.

[0033] At the same time, driven by wind, dust accumulates at the lowest point inside the air guide box 136, and excess gas inside the air guide box 136 will be discharged from the inner walls on both sides of the air guide box 136, achieving the effect of cleaning and scraping off the dust accumulated and adhered to the inner walls of the air guide box 136, avoiding the continuous accumulation of dust adhering to the inner walls of the air guide box 136, which will affect the ventilation efficiency on the surface of the air guide box 136 and make the gas unable to ventilate effectively and quickly.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
