Description

Technical Field

[0001] The utility model relates to the field of sampling, in particular to a sampling device used in a wind separator. Background Art

[0002] The air separator is also called an air separation pulverizer. It consists of coarse crushing, fine crushing, wind conveying and other devices. It uses high-speed impact to achieve the purpose of crushing and uses wind energy to turn it into powder in one go. The air separation pulverizer is used to supply materials from storage bins or other storage equipment to the receiving equipment evenly or quantitatively.

[0003] The Chinese patent with patent number CN211914219U discloses a "sponge titanium wind selection sampler". The fan extracts the air in the cyclone dust collector to form a negative pressure, which can attract the material-containing air, thereby forming a cyclone, realizing material sedimentation, and collecting the material through a collecting tube. The sampling tube is a hollow structure. During wind selection, the direction of the collecting hood is consistent with the wind direction, which can prevent the wind-selected material from entering the collecting hood and blocking the sampling tube. During sampling, the collecting hood is directly opposite to the wind direction, and the wind-selected material can directly enter the sampling tube, thereby easily obtaining a material sample. The structure is simple, the operation is convenient, and it is convenient to evaluate and detect the wind selection effect.

[0004] Although the above-mentioned titanium sponge air selection sampler has certain advantages in sampling ability, it is usually necessary to sample the material in sections, and the collection tube can easily obtain material samples, but it is not possible to sample materials at different time periods separately, which is not convenient for evaluating the overall air selection results.
