DEVICE FOR DETECTION OF SOLIDS Russian patent published in 2016 - IPC G01N1/22 G01N27/62 G01N30/04 G01N33/22 

FIELD: instrument making.

SUBSTANCE: invention relates to a device for detection of solids, in particular explosives or narcotic drugs. Device comprises carrier disc (20), on which multiple screens are disposed with rotation symmetry. Screens in first rotational position (21) are provided with intake channel (42) for ambient air suction through corresponding screen. Screens in second rotational position (22) are provided with first heating element (40) to evaporate solids captured by corresponding screen during intake of particles. First intake channel (43) for drawing of evaporated particles is connected to analyzing device (45). Angular distance between two adjacent screens of carrier disk (20) is even multiple of angle α, which the carrier disk (20) passes through during the transition from one rotational position of the carrier disk (20) to an adjacent rotational position. Carrier disk (20) is structured with rotation symmetry, in such a manner that as the result of rotation of the carrier disk (20) by the angle a, from one rotational position to the next, a switch from a screen to a blind spot (31), or vice versa, so that intake and aspiration channels (42, 43) are closed off by blind spots (31) in every other rotational position. Blind spots (31) of carrier disk (20) between two screens have plug, which is in the shape of the screen, said plugs are made from non-magnetic, preferably austenite, material.

EFFECT: higher efficiency of the device, higher degree of loading and efficiency of operation of the used components.
