The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a fog and collection integration mechanism technical scheme are sent out to air intake efficient, send out dirt pipeline 1 and annular sampling pipeline 2 including the annular, equidistant circumference is provided with four fixers 5 between dirt pipeline 1 and the annular sampling pipeline 2 is sent out to the annular, send out dirt pipeline 1 and annular sampling pipeline 2 between through four fixer 5 fixed connection, eight dust outlets 3 have been seted up to the inboard of dirt pipeline 1 and the equipartition interval circumference in the outside of annular, eight sampling ports 4 have been seted up to the inboard of annular sampling pipeline 2 and the equipartition interval circumference in the outside, fixed cup joint installs on the dirt pipeline 1 and sends out dirt conversion equipment 8, one side of sending out dirt conversion equipment 8 is provided with sends out dirt and concentrates filling opening 6, fixed cup joint installs sampling conversion equipment 9 on the annular sampling pipeline 2, one side of sampling conversion equipment 9 is provided with and sends out dirt and concentrates sampling port 7.

Preferably, the fixing device 5 is fixed with the annular dust generating pipeline 1 and the annular sampling pipeline 2 through welding, the annular dust generating pipeline 1 is fixed with the annular sampling pipeline 2 through the fixing device 5 through welding, and the distance between the fixing device 1 and the annular sampling pipeline 2 is adjusted through sampling the length of different fixing devices 5 so as to meet the dust generating and sampling precision under the conditions of different wind speeds and different air flows.

Preferably, the one end that injection port 6 and the sampling port 7 were concentrated to the dust-emitting all is provided with clamp 11, cramps the kneck with clamp 11 for the PVC hose, avoids the kneck to reveal, influences the dust-emitting and sampling result.

Preferably, the dust-generating concentrated injection port 6 and the dust-generating concentrated sampling port 7 are of pagoda-shaped structures, and firmness of the dust-generating concentrated injection port 6 and the dust-generating concentrated sampling port 7 during connection of PVC pipelines is enhanced.

Preferably, a flow equalizing plate 10 is fixedly installed at one side of the annular dust generating pipe 1, so that the air flow can be uniformly distributed, and the function of protecting the filter can be achieved to a certain extent.

Preferably, the diameter of the annular sampling pipe 2 is smaller than that of the annular dust generating pipe 1, so that the suction force of the annular sampling pipe 2 is increased, the suction force of the sampling port 4 is indirectly increased, and the suction intensity of the sampling port 4 is ensured.

The working principle is as follows: before the dust generating device is used, the safety of each structure of the dust generating device is checked, when dust is generated, the dust generating concentrated injection port 6 is externally connected with a PAO particle dust generating device through a PVC hose, and PAO dust generating particles are injected into the annular dust generating pipeline 1 through the dust generating conversion device 8. During sampling, airflow enters the annular sampling pipeline 2 through the sampling port 4 and is gathered into the dust-emitting centralized sampling port 7, and the dust-emitting centralized sampling port 7 enters the particle counter for counting through the PVC hose and the PAO particle counting device externally connected with the PVC hose. In practice, in order to increase the suction force of the annular sampling pipe 2, the diameter of the annular sampling pipe 2 is generally slightly smaller than that of the annular dust generating pipe 1. Thereby increasing the suction force of the annular sampling pipe 2, indirectly increasing the suction force of the sampling port 4 and ensuring the suction intensity of the sampling port 4. When PAO dust generation is carried out, PAO particles are input into the annular dust generation pipeline 1 through the PVC hose to the dust generation conversion device 8, and are uniformly conveyed into the box body through the sixteen dust generation ports 3 uniformly distributed on the side edge of the pipeline. During sampling, sixteen sampling ports 4 on the annular sampling pipeline 2 positioned below the annular dust generating pipeline 1 absorb airflow in the pipeline from all directions, corners and edges of the box body, converge to the dust generating concentrated sampling port 7 and transmit the airflow to the PAO particle counting device through PVC hoses. The dust-generating concentrated injection port 6 and the dust-generating concentrated sampling port 7 are generally in a pagoda shape, and are hooped at the interface with the PVC hose by the hoop 11, so that the interface is prevented from being leaked, and the dust generation and sampling results are prevented from being influenced. In general, the dust generating and sampling mechanism apparatus of the present invention is used in conjunction with a flow equalization plate 10, refer to fig. 2.
