Fig. 2 is an exploded view of the preferred embodiment.
Detailed Description
Referring to fig. 1 and fig. 2, a fresh air filtering structure for mobile combined PCR laboratories comprises a three-way ventilation pipe 1, wherein the three-way ventilation pipe 1 is in a Y-shaped structure, and the rear end of the three-way ventilation pipe 1 is used for connecting units corresponding to each laboratory through pipelines and conveying fresh air to the units;
the front end of the three-way ventilation pipe 1 is branched into two independent interfaces, the interfaces are connected with one-way pipe valves 11, the one-way pipe valves 11 are butterfly one-way valves, the one-way pipe valves 11 have a closing function under the action of self gravity, when the butterfly valves are acted by air pressure, the one-way pipe valves 11 are automatically opened, locking parts 111 are arranged at the tops of the one-way pipe valves 11, and when the one-way pipe valves 11 are in a closing state, the vertical positions of the butterfly valve blades can be limited through the locking parts 111, and the one-way pipe valves 11 are in a locking closing state;
the front end of the one-way pipe valve 11 is provided with a corrugated damping pipe 12, the corrugated damping pipe 12 has certain flexibility and bendability, when a fan at the rear end operates, the transmission of vibration can be reduced through the corrugated damping pipe 12, and noise generated during the operation of the system is reduced and is transmitted to the inner space of the laboratory through a ventilation pipeline;
the front end of the corrugated damping pipe 12 is connected with a second connector 13, the outer edge of the second connector 13 is provided with a three-sided clamping frame 131, the outer edge of the central pipe orifice is provided with an O-shaped sealing ring 132, and a D-shaped sealing ring 132 is arranged around the outer edge of the O-shaped sealing ring;
the front end of the second interface 13 is provided with the first interface 14, the outer edge of the first interface 14 is provided with a flanging structure 141, the flanging structure 141 can be inserted into the inner side of the clamping frame 131, after the first interface 14 and the second interface 13 are clamped and combined, the two interfaces can be tightly attached due to the double elastic sealing action of the O-shaped sealing ring 132 and the D-shaped sealing ring 132, and a better airtight effect is achieved;
the outer side of the second interface 13 is provided with a convex block 134, the outer side of the first interface 14 is provided with a quick-connection buckle 142, and the quick-connection buckle 142 can be matched with the clamping block 134 and enables the second interface 13 and the first interface 14 to be stably connected.
The front of the first interface 14 is connected with a fresh air component, the fresh air component comprises a high-efficiency filter screen 15, a primary filter screen 16 and a fan 17, wherein the primary filter screen 16 and the high-efficiency filter screen 15 are both of folding bag type structures, the primary filter screen 16 is mainly used for filtering dust particles with the particle size of more than 5 micrometers, the high-efficiency filter screen 15 is HEPA (high efficiency particulate air filter), and the filter efficiency of the particles with the particle size of 0.1 micrometer and 0.3 micrometer is more than 99.7%.
The front end of the fan 17 is connected with a downward bent ventilation pipe 18, and the ventilation pipe 18 can be connected with outdoor air, an air refrigeration part or an air supply cabinet and is used for providing a proper air source for a fresh air part.
This new trend filtration, when normal work, there is a set of new trend parts to filter and the operation of new trend supply, another set of new trend parts is in the closed condition, at this moment, its relative one-way butterfly valve 11 also is in the closed condition, when a set of new trend parts need to be maintained or maintained, only need open another set of new trend parts earlier, then close the one-way butterfly valve 11 that needs a set of new trend parts of maintaining, and make it be in the locking closed condition through locking part 111 of one-way butterfly valve 11, later through first interface 14 of separation and second interface 13, can realize corresponding maintenance operation.
In conclusion, the main body of the scheme adopts a parallel fresh air filtering structure, and the air supply after dragging is realized through two sets of fresh air components which can be independently disassembled, so that the long-term stable and uninterrupted fresh air supply can be ensured, and because the conventional fan cannot work continuously, but for a mobile combined PCR laboratory, the stable and durable air pressure supply must be included to deal with a positive pressure unit or a negative pressure unit;
when materials such as a filter screen and the like need to be replaced, the operation can be carried out only by correspondingly closing one group of structures, so that the stability and the reliability of fresh air supply are greatly improved, and positive pressure air supply or negative pressure air supply of a corresponding unit in a laboratory can be ensured;
because the removal characteristic of removal combination formula PCR laboratory, traditional new trend air supply pipe network is arranged comparatively inconveniently, and the new trend filtration of this scheme need not the pipe network to carry out complicated transformation to the mechanism is simple, and it is convenient to maintain, and stability is good, has better popularization meaning.
