    The invention relates to sample preparation devices for determining representative chemical and / or physical parameters of a material under investigation. The aim of the invention is to obtain a representative sample, preventing damage and clogging the filter. For this, the device is equipped with a transfer bin located between the two belt conveyors in the transport direction, the suction opening is located inside the transfer bin but at a distance from the flow of bulk material and provided with a suction pipe with a hollow cylindrical body of the first filter, also made hollow cylindrical and equipped with a vibrator. The housing of the first filter is connected to the analytical and suction devices. The inlet of the selected material into the body of the first filter is made tangential, and the suction pipe is in the form of a flexible, resistant to abrasive hose wear. The suction inlet in the wall of the transfer hopper is hermetically sealed. The first hollow cylindrical filter is made in the form of a sieve, coaxially mounted in a hollow cylindrical body and provided with a rotor in the form of a hollow shaft with a frame and transverse tubes with openings oriented against the surface of the sieve. The hollow cylindrical body of the first filter has a hole in the bottom and is equipped with a valve with an actuator.

    The invention relates to sample preparation devices for determining representative chemical and / or physical parameters of a material under investigation.
    Closest to the proposed technical solution is a device for sampling from a stream of bulk material coming from a giving conveyor belt to a receiving one for subsequent chemical and / or physical analysis, containing a suction device with a suction pipe, the first and second filters with cylindrical hollow housings, and pipelines.
    A disadvantage of the known device is that the first filter is easily clogged and the device can be easily damaged due to the ingested material on the first filter.
    The aim of the invention is the possibility of obtaining a representative sample,
    prevent damage and filter plugging.
    FIG. 1 shows the proposed device, side view; in fig. 2 shows section A-A in FIG. one.
    The device consists of a transferring 1 receiving 2 belt conveyor, between which a transfer bunker 3 is located, consisting of four restrictive parts 4-7, walls that limit a generally rectangular (in this case approximately square) cross section that increases in the lower direction up. The rear limiting part 4 and both lateral limiting parts are of such dimensions that they are practically hermetically connected to the receiving conveyor 2. The bunker is connected to the conveyor by means of reflectors 8 made in the form of strips. Conveyor 2 has an upper branch 9. The restrictive wall 5 is located at a distance from the upper branch 9 of the conveyor, forming an opening 10 through which the material is transported. On the back wall 4 there is a hole 11 through which the suction pipe in the form of a flexible tube 12 with a suction hole 13 connected to the suction device in the form of an exhauster 14 is passed. The powder is pumped into the cylindrical hollow body 15 of the first filter 16.
    The body is made with the top 17 and bottom 18 holes, and the hole 18 is locked by means of a valve 19 with an actuator 20. Inside the case there is a first filter 16 made in the form of a cylindrical hollow sieve with a bottom 21. Inside the first filter there is a rotor 22 made in the form of a hollow shaft 23 with a frame 24 and transverse tubes 25, made with holes 26. A rotor is driven by an electric motor 27.
    The movement from the electric motor 27 to the rotor 22 is transmitted by means of belt pulleys 28 connected by a belt 29. A vibrator 30 is mounted on the base of the first filter. The first filter 19 is connected to the actuator 31. The opening 17 of the first filter 16 is connected via a pipe 32 to a second cylindrical hollow sieve filter 33, which is located inside the second cylindrical housing 34. The inner space of the housing 34 is connected to line 35, to the other end of which the exhauster 14 is connected. Between the building catfish 34 and exhauster 14 included a sump 36, made in the form of a cyclone.
    The second filter 33, located inside the second housing 34, continues into a large-diameter line 37, in which two sieves 38 and 39 are located, transversely
    penetrating the line 37 at an inclination in the direction of the hole 37 located in the wall of the line 37, which is locked by the valve 41 with the actuator 42. The pipe 43 for introducing material into the cylindrical hollow body 15 is installed tangentially. The second filter 33 is connected via a conduit 44 to an analytical device (not shown).
    The device works as follows.
    The fine-grained material sucked through the flexible suction pipe enters the cylindrical hollow body 15, in which it exerts pressure on the external mesh surface of the cylindrical hollow sieve 21 and enters line 32,
    Particles larger than the mesh diameter of the mesh surface
    5 of the filter 21, partially falling downward from the outer surface of the filter. The largest particles fall down, while the smaller ones remain on the outside of the filter. In order to line them up, the filter is equipped with a vibrator 30, which shakes it periodically. The coarse fraction accumulating in the lower part of the housing 15 is removed through the opening 18. The fine-grained material separated in this way enters
    5 in the second filter 33. Here is the separation of the most fine fraction. The mixture of dust and air containing this fine fraction is first directed through line 35 to a cyclone 36, in which solid
    0 is precipitated, after which the solid is removed from the cyclone. Thus, the middle fraction, which is representative of the material of the transported flow, falls into line 37. This fraction
    5 goes to research on the analytical device.
