Description

The invention relates to pneumatic conveying of bulk materials, namely to paddle unloaders of pneumatic installations for conveying loose materials, and can be used to transgurtate and distribute end feeds on livestock farms. The purpose of the invention is to reduce the dust content of the environment. The drawing schematically shows a pneumatic unloader for transporting bulk material, a general view. Unloader Contains an inlet 1, on which, with the help of a detachable bearing assembly 2, a cone-shaped body 3 is suspended, consisting of a series of sections and connected to a compartment for unloading material made in the form of two conjugate truncated cones 4 and 5. In body 3 The shaft b is rigidly fixed along the longitudinal axis on the brackets 7 and 8. On the shaft 6 along the helical lines, which may be two or more, the blades 9 are fixed. The opposite end of each blade 9 is installed in the housing 3 with the ability to adjust the angle of the blade 9 flax direction of movement of the injected material at pomoshi lever 10 and a bolt 11. The truncated cone 4 for the material discharge compartment has an upper cylindrical portion of small diameter openings 12 for air passage, a truncated cone 5 has a window 13 for output of material. The cone 5 is blocked by a conical bottom 14. The pneumatic unloader of the pneumatic installation for transporting bulk materials works as follows. The material transported by compressed air from the inlet nozzle 1 enters the body 3 of the unloader, where it interacts with the blades 9. The blades 9 with the help of the lever 10 and the bolt 11 are set at the optimum angle, which allows the transported material to be most effectively separated from the air the force received from the input material under pressure on the body 3 of the unloader. as a result, the latter begins to rotate on the bearing assembly 2 around its longitudinal axis. The rotational speed of the unloader depends on the pressure of the input material and the angle of inclination of the blades 9. The number of sections of the housing 3 of the discharger is chosen depending on the pressure and mass of the material being injected. In the truncated cone 4 compartments for unloading material under the action of centrifugal and gravitational forces, the material is finally separated from the air. Air escapes through the cylindrical holes 12, and the material through the discharge ports 13 of the truncated cone 5. The conical shape of the bottom 14 contributes to a more complete separation of the material from the air.
