Description

The invention relates to the storage and transportation of bulk materials, in particular to a warehouse of fine particulate materials.

The purpose of the invention is to increase the productivity of the warehouse while reducing its height dimensions.

The drawing schematically shows the proposed warehouse, a longitudinal section.

Warehouse contains airbrush 4, made V-shaped in longitudinal section and consisting of transport 2 and air-conducting 3 channels separated by an airtight partition 4, Canal 1 is connected by loading nozzles 5 with expansion 6 in the lower part with hoppers 7 mounted in one the tank 8 reported to the source

Vacuum (not shown) At the junction of the inclined parts of the channel has a pipe 9 with extension 10, connecting channel 2 with a tank 8, a discharge window 11 and an air supply pipe 12. A discharge pipe 13 is attached to the discharge window 11, which is connected to reception dozatoro 14, having a shutter - for example, a valve-flasher, pneumatic seal, etc. which excludes air suction through the discharge port 13. In the lower part, the next stage 15 of transportation is located (for example, gravity hydraulic channel, pneumatic screw feeder, etc.).

The warehouse is discharged as follows.

Bulk material enters the airgel 1 via the loading nozzles 5 with an extension in the lower part 6 of the bun

7 in the air duct 3, on the partition 4, the material fluidizes, acquiring flow properties and, due to STR, gravity moves two streams to the discharge window 11, from which the discharge pipe 13 through the dispenser 14 enters the next transport stage 15. The exhaust air through the pipe 9 through the pipe 10 is removed into the tank 8, which is under vacuum. Unloading of bulk material starts from 11 bins 7 that are closest to the discharge window, and as the installation works 5 with an expansion of 6 in the bottom of the emptied bins 7 are put into suction operation, which deepens the vacuum in the transport channel 2 and compensates for the increased exhaust air speeds due to an increase in the dpina of aerated transportation sites. The suckers from the outside block the gates of the metering device 14. Thus, the degree of aeration of the material by connecting new suction points along the length of the transport channel 2 is equalized, and the exhaust air in the upper part of the transport channel 2 is uniformly drawn into the empty hoppers 7 and the tank 8 ,. under vacuum. When the bulk material from all the bins 7 is fully drained, the air supply to the air inlet duct 12 is stopped, the dosing unit 14 is blocked, the entire installation is sealed and under vacuum. As the material accumulates in the hoppers, the unloading cycle repeats again.
