Description

FIG. 1 shows schematically a cargo route proposed aero and; amine device; figure 2 is the same, top view; in fig. 3 - section A-L in FIG. 1

The aerodynamic device consists of a fan 1 with an electric motor 2 and a variator 3, an air inlet 4, a housing 5, a louvre shutter 6 and a partition 7, which divide the case 5 into a conveyor channel 8 to the upper 9 and the lower 10 channels. Partition. 7 has valves 11-13 and window cl. performing the workflow of an aerodynamic device with a local supply of hack transported material to the initial and to the old part of the conveyor. The material is loaded through feeder 14,

Aerodynamic device works in the following way;

When the material is fed to the initial part of the conveyor, the valve 11H is set to the lower position, and the co-channel 10 is switched off from work; The cells 12 and 13 are set to 1E-1 neutral position, i.e. the windows and partitions 7 overlap. When the fan 1 is operating, the conveyed material supplied by the feeder 14 is trickled from the air flow coming out of the slot channels formed by the flap - 1I grate 6, moves along the surface of the grille and in the end part of the device comes out of the transport. Channel 8.

When the material is fed to the middle part of the louvered grill, for example, from the warehouse section, valves 11 and 12 are set to the upper position and valve 13 is set to the lower position. Subsequent valves of the septum in the direction of movement of the material are installed. in a neutral position. With this valve installation, the air moves through the lower part of the nozzle 4 through the lower y channel 10 passes through the channel formed by the valve aNiH 12 and 13 and located in the zone of material supply by the feeder 14, and. through the holes of the working length of the re 6 goes into the channel 8 and carries out the movement of the material. The installation of valves 11-13 prevents the air from escaping through the openings of the inactive part of the grid 6 and the increase in power consumption and causes an increase in the throughput of the device due to its rational use. of air. In addition, the exit of the air flow from the channel formed by the valves 12 and 13 and the nodal passage in zone 5 of supply of material to the grille louver at an acute angle to the surface of the lattice contributes to the communication of the material: kinetic energy, stabilization of the material transportation process and increase device performance

When unloading material from the subsequent sections of the warehouse, the windows and partitions 7 are located; 1 are before and after

S material feeds are closed by valves 12 and 13, and a window located in the loading area of the grille is openly corresponding to the installation of its valves. In this technological

The rspouecc of the aerodynamic trough proceeds in such a way, as when feeding material from section II of the skla.da.
