Description

one.. ,

The invention relates to reloading dust removal devices and can be used to prevent seepage from the discharge gallery to unload rail 4 jBbtx cars into bunkers. . A device for preventive maintenance & .. .. no removal of dust from the discharge gallery mainly yrie unloading Zhelee. No-rail cars containing twin elastic curtains attached to the gallery, nozzles of the under-car air curtain and air ducts l.

This device blows out dust, but “& ensures the achievement of the norm, as it provides only local dust removal, does not remove dust that has settled on the cars, does not affect the removal of dust through through blowing, which leads to clogging of the environment when the cars exit the discharge gallery.

The aim of the invention is to improve the dedusting of the associated air flows and the removal of dust and dust accumulated on the cars.

resistance to dust removal by blowing through.

This goal is due to the fact that the device contains precipitated vestibules with seals, one of which is adjacent to the discharge gallery and is equipped with 5ps, for example, connecting ducts with a discharge chamber.

FIG. 1 shows the proposed device, longitudinal 1st section; in fig. 2 airway drains for railcars, cross section.

The device consists of a discharge gallery 1, sedimentary platforms 2 with

5 ymiOTHeHHsEvjH 3 vestibules, twin elastic curtains 4, connected by duct 5 through fan 6 to the nozzles 7 of the sub-car air curtain ..

Claims (1)

In the vestibule, which is attached to the discharge gallery, stands 8 are installed with guide channels 9 and a recirculation duct 10 with a fan 11. The recorder 12 directs the movement of the cars to the sensor 13 for wind direction to control the dedusting system. The device works as follows. When submission of cars to the discharge gallery 1 include the fan 6 and the fan 11 of the air curtain blowing. The cars are unloaded and, continuing to double, carry the air stream out of sight until they meet with the seals of the 3 gates of the first vestibule, where it is blown from the bottom of the rack 8 through the air curtains 9, which blow the blown dust back into the area. 1, this air is used in a circular cycle with the help of a duct of recirculation feed from the fan 11. Part of the dust settles in the first vestibule, so the car kicks back again when the cars move through the seals 3 of the second gate, after which the leaked dust is trapped double The elastomeric curtains 4 are guided by the air duct 5 from the fan, b to the undercarriage clearance of 7 7. Further, a second sedimentary platform 2 is located towards the seal 3 of the gate openings, preventing the escape of residual nine streams into the environment. When empty dusty cars are pulled in the opposite direction, previously operating fans are wiped off and include similar systems from the opposite side of the gallery, where there are also precipitation platforms with seals for door openings, an anti-ejection device and a blowing air curtain. To prevent dust from escaping from the gallery between the car intakes, the fans of the air curtain 11 are turned on from the side of the galleries opposite to the wind. Claim 1. Device for preventing the removal of the gas from the discharge gallery, mainly when unloading railway cars, containing twin elastic curtains attached to the gallery, car air curtain nozzles and air ducts, characterized in that, in order to improve dust removal of passing air and removing settled air on the cars they were dry, and to counteract the dust output through blowing through it contains precipitation vestibules with seals, one of which is adjacent to the loading gallery and is equipped with about kami with guide ducts connected to the cavity razgruzochtyuy gallery.
