(54) INJECTION JET FOR PNEUMATIC TRANSPORTATION OF BULK MATERIALS

I

This invention relates to the pneumatic transportation of bulk materials; namely to the jet feeder m.

Known for the main author. St. No.695919 jet feeder for pneumatic transportation of bulk materials containing a transport pipeline, in front of which there is a nozzle, connected to a source of compressed air and mounted on the pipeline with the ability to move along the axis of the pipeline, in front of the nozzle a chamber connected to it, to which nozzles tangentially attached, located at some distance from each other, and connected to s axis of the casing pipe associated with the source of compressed air, and covering a gap transfer line on which are mounted sealing rings, cooperating with the inner surface of the casing, and the chamber is mounted a conical rod located coaxially with the transport conduit and the conductive input

inside of it, the feeder being equipped with a nozzle moving mechanism fixed on the pipeline and connected to the casing 1.

However, the performance and concentration. The traction of the air-jet mixture of such an jet feeder depends on the amount of bulk material flowing by gravity to the inlet of the transport pipeline. With a decrease in the pit depth, the pressure of the leach layers of the bulk material decreases and the performance and reliability of the feeder decreases.

The purpose of the invention is to increase the performance and reliability of the operation of the feeder.

This goal is achieved by the fact that the impeller is mounted on the cone rod and the drive for the rod rotation in the chamber.

In addition, the impeller is made with vertical blades. However, it can be performed with inclined blades.

Claims (3)

When the feeder is working, the impeller blades rotate in the bulk material and continuously capture the material and feed the inlet of the transport pipeline, and the transporting air, which has flowed out of the nozzle, continuously blows into the transport pipeline the gripping bulk material with increased concentration. FIG. 1 shows a jet feeder, a general view in section; in fig. 2 is a view A of FIG. one; in fig. 3 — node 1 in FIG. one; in fig. 4 shows a section BB in FIG. 3. A nozzle 2 for supplying compressed air is installed in front of the inlet of the transport conduit 1. Camera 3 is attached to nozzle 2 with drive 4 located in it (electric motor, hydraulic motor). The actuator body 4 is simultaneously a dissecting nozzle 5. The nozzles 6, which are located at a certain distance from each other, are tangentially attached to the chamber 3. Nozzles 6 are connected to a housing 7 that is movable along the axis of the pipeline, to which is attached a nozzle 8 connected to a source of compressed air (not shown in the drawing). On the axis of the actuator 4 is mounted a tapered rod 9, on which the impeller 10 is mounted. The tapered rod 9 is located coaxially with the transport pipeline 1 and enters inside it. Spiral ribs 11 are located on the outer surface of the casing 7 to immerse the feeder in the bulk material and the handle 12. On the transport pipe 1, sealing rings 13 are mounted, which interact with the inner surface of the casing 7. The feeder is equipped with a mechanism for moving the nozzle and opening the impeller 10 consisting of a cap nut 14, a support nut 15, a key with a handle 16, guide rails 17 and shafts 18. The guide rails are mounted on the pipe 1 parallel to the longitudinal axis and the obui and 00 extend the longitudinal groove for the stud 18, mounted on the casing 7. Inkjet feeder operates as follows. The feeder may be immersed in a bulk material, for example, screwing it with spiral ribs 11 and handle 12 or with a vibrator. Before immersing the feeder into the bulk material, the housing 7 closes the inlet opening of the transport pipeline. After the feeder is immersed in the bulk material, compressed air is fed through the nozzles 8 into the annular channel formed by the casing 7 and the transport conduit 1, and the impeller drive 4 is started. When the support nut 15 rotates, the transport conduit 1 moves, for example, this opens up. When the actuator 4 rotates, the blades of the impeller 10 capture the bulk material from the surrounding space and feed it to the receiving opening of the transport pipeline 1. Compressed air from the annular channel in the lower part of the feeder enters the chamber 3 through the tangential nozzles 6. and, in the form of a rotating hollow cone-shaped flow, flows out from the annular channel formed by the nozzle 2 and the rod 9 into the transport pipeline 1 to the aerator and blowing out flowing material Therians captured by the vanes of the impeller 10. Because the conveying line 1, the bulk material with the air flow supplied for example in a cyclone, wherein the particulate material is separated from the carrier stream. The jet feeder can be used both in the injection pneumatic conveying lines and for operation in the composition of the vacuum and displaced vacuum-pressure lines. Claim 1. Inkjet feeder for pneumatic transportation of bulk materials by ed. St. No. 695919, characterized in that, in order to increase production, stability and reliability, the impeller is mounted on the tapered rod, and the impeller is mounted in the casting rod, the measure is the drive for rotation, and the measure is the drive for rotation of the rod. 2. A feeder according to claim 1, characterized in that the impeller is made with vertical blades. 3. A feeder according to claim 1, characterized in that the impeller is made with inclined blades.
