Abstract

; This invention relates to the pneumatic supply of bulk material. The purpose of the invention is reliability of work. A device for pneumatic conveying of powdered material contains a hopper 1 with an elastic conical bottom 3, rigidly interconnected and mounted with the possibility of vertical movement of the air duct 2, device 4 and the transport pipeline 5, connected in turn with the bottom 3 of the hopper 1 When the position of the device 4 is above the level of the material, the material is not transported, and the elastic bottom 3 faces with a cone upwards. After the material has been loaded into the bunker by means of the device 4, as well as the associated air duct 2 and pipeline 5, are lowered. Through the device 4, which is lowered into the layer of material, the material is loaded into the pipe 5 and is blown out with air from the air pipe 2 into the transport line. 2 Il.

Description

15

The invention relates to a device for forming a gas-powder mixture and can be used as a powder feeder during plasma spray coating.

The aim of the invention is to improve the reliability of the device.

Figure 1 schematically shows the pre-1 o lag device in the working position; figure 2 - the same, in the off position.

A device for pneumatic conveying of a powdery material contains a hermetic vertical bunker 1, inside of which an air line 2 coaxially is placed, communicating with a source of compressed gas, for example air. The bunker 1 is made with a plastic-elastic conical bottom 3. In the area of the bottom 3 a device 4 is placed, fixed in the gap between the ends of the air duct 2 in the transport pipeline 5 connected with a collar

6 with an elastic conical bottom 3. The air duct 2 and the pipeline 5 are rigidly connected with each other and with the rod

7 drive them vertical displacement. Device 4 reports the

the duct 2 and the transport pipeline 5 with the cavity of the hopper 1 and serves to load material into the transport pipeline. Bunker 1 is complete with

Into the hopper 1. At the same time, device 4 is placed above the level of the material and the material does not enter the transport pipeline 5. After the material is loaded by the rod 7, a rigidly connected air duct and pipe move downward from the drive 7, device 4 is lowered into the layer of material. Through the device 4, the material enters the transport pipeline 5 and is blown by the air flow from the air pipe 2 to the main

By vertically moving the air duct 2, the tools 4, and so on. The transport conduit 5 achieves quick and reliable switching on and off of the pneumatic material supply.
