Abstract

The invention relates to devices for distributing material flows in the pneumatic transport systems of various technological processes and can be used in the production of building materials, food, chemical, metallurgical industries. The purpose of the invention is to increase the efficiency of work. The goal is achieved by installing a semipermeable partition 12 in the upper part of the housing I, through which a uniform suction of fluidizing air is provided along the nozzles 8 lines 9 using the ejector 13 and the subsequent discharge of this air into the channels 4 to increase the material. 2 z.p..f-ly, 1 ill.

. invention - improving the efficiency of work.

The drawing shows schematically the distributor 9 general view.

The distributor contains a cone-shaped body 1, oriented upward, made with double side walls 2 and 3, forming channels | 4 for delivering material to the main of the pneumatic conveying system. The jB of the upper part of the body is fixed with a vertical pipe 5, at the main / end of the end of which | 6 the supply line 7 is fixed coaxially with it, as well as a branch pipe 8 for exhausting air with: a suction line 9 carrying I air. The same pipe 8 and line 9 are fixed in the upper part of the housing I1. (The drawing shows a distributor diagram into two canapes). When splitting the flow into a larger number of channels, the number of nozzles 8 with lines 9 increases proportionally. Even an even number of channels, ale pipes 8 can be evenly distributed between the end of the vertical pipe 5 and the upper one. part of housing 1, and with an odd number of channels, a greater number of nozzles with suction lines 9 is installed where more withdrawal is required (mainly at the end of the vertical pipe 5). In the lower part of the housing 1. there is an aeration bottom 10 installed with a central conical divider 11. In the upper part of the housing 1, a semipermeable partition 12 is installed coaxially with a vertical tube 5,

 In line x 9 suction transporting one. gas ejectors 13 are installed, the displacement chambers 14 are connected to the channels 4 for dispensing material, and the high-pressure chambers 15 are connected to the autonomous supply air shishya 16. Regulating valves 17-19 are installed respectively in the air supply lines to the ejectors 13, the suction air transport lines 9, and in the air supply line to the air distributor 10.

The distributor works as follows.

In the initial position, the valves 17-19 are closed and the bulk material is not fed into the housing I.

When the distributor transitions, the operating mode opens the valves 17-19, which supply air (or another gas) to the corresponding devices. Then the dispersed material is fed through a pneumatic conveying line into the housing 1 through the supply pipe 7 of the vertical pipe 5. The material falls onto the conical splitter 11 and spreads over the aerating bottom 10, and the air transporting it is drained from the separation volume between the vertical pipe 5 and the supply pipe 7 the ejector 13 through the pipe 8, mounted on the end 6, This is not terrible and possible suction of dust, since the aspirated air is then sent to the process line (channel 4). However, with a high suction intensity, it can be adjusted by means of a valve 18 installed on the suction line 9.

. Next, the bulk material from the conical dissector 11 to the aerating bottom 10 fluidizes, fills the peripheral volume of the housing 1, rises to the level of the walls 3 and begins to flow into the channels 4. The aerated air then flows out of the ejector 13 through the semipermeable wall 12 and installed in the upper part the body of the pipe 8. Similarly to the opsii suction can be adjusted by the corresponding valve 18,

Uniformly separated streams of dispersed material, initiated by air coming from ejectors 13, are further transported via channels 4 to their destination in accordance with the technological scheme
