SU401617A1 - DEVICE FOR PREVENTION OF REMOVAL OF THE DUST FROM THE LOADING GALLERY - Google Patents

Description

one

The invention relates to devices that prevent the ingress of dust when discharging dust-like materials.

Devices are known for preventing dust from escaping from the discharge gallery through the door opening, including a ventilation duct system and a fan. The disadvantage of these devices is the dusty air flow that occurs when the train composition moves during unloading.

The purpose of the invention is to provide resistance to the movement of dusty streams when unloading wagons. This is achieved in that the device is provided with double elastic tongues located at the gate with gaskets between them for air suction, connected by a fan with air curtain nozzles, supplying air into the subcarriage space towards the air currents carried by the moving car.

In order to close the door opening in the absence of cars in the gallery, the device is provided with a shield mounted on a trolley moving with the cars.

FIG. 1 shows the proposed device; in fig. 2 is a section along A-A in FIG. one; in fig. 3-section along BB in FIG. 2; in fig. 4 - a cart with a shield in the doorway; FIG. 5 is a view along arrow B in FIG. four.

The device is mounted in the opening of the gate of the gallery 1, where the cars 2 are unloaded and contain a seal of two rows of elastic tongs 3 with gaskets 4 (see Fig. 3) between them and the air duct 5 surrounding them, connected to the fan 6, which is connected to the pipe line 7 with nozzles 8 located under the car 2. The unloading cars are coupled with the carriage 9, on which the shield 10 is mounted.

The device works as follows. The cars 2, stitched with the cart 9, are inserted into the opening of the gate of the gallery 1, with the shield 10

adjoins shchitor. The fan 6, by means of the air duct 5, sucks air from the space between the curtains 3, creating a discharged area along the contour of the car 2, which prevents the removal of dust from the gallery. Aspirated

air is injected into the car space through the nozzle system 8 to prevent dust from escaping into the lower part of the gate opening. At the same time, to avoid additional dusting, air jets are directed inside

galleries 1.

In the absence of cars, the carriage 9 moves the shield 10 until it comes into contact with the curtains 3. The carriage 9 is set to the desired position by the disengagement mechanism 11, which disengages the carriage 9 from the cars 2. Subject of the invention 1. Device for preventing dust from escaping from the discharge gallery through the gate opening , including a ventilation duct system and a fan, characterized in that, in order to counteract the movement of dusty streams during unloading of cars, it is equipped with double elastic bodies located at the gate and curtains with gaskets therebetween for air suction communication zapnymi through fan nozzle vozduschnoy curtain undercar feed air into the space toward the air flows bearable moving carriage. 2. A device according to claim 1, characterized in that, in order to close the gate opening in the absence of cars in the gallery, it is provided with a shield mounted on a trolley moving together with the cars.
