Abstract

This invention relates to the pneumatic supply of bulk materials. The purpose of the invention is the expansion of technological capabilities by means of dosing of the material. The chamber feeder contains a tank 1, a cover 2 with holes 3, a transport pipeline 4, a compressed gas supply pipeline 5 surrounded by a casing 6. In the annular gap 7 between the housing 6 and pipeline 5 a spool 9 arranged in the form of a stepped cylinder is placed with the possibility of vertical movement covering pipe 4. In the spool 9 and pipe 4 there are radial holes 13 and 12. The material is loaded into container 1 through holes 3. The valve 9 is in the upper position, overlapped ti (L

page 12 of the transport pipeline 4 and opening the passage of compressed gas from the pipeline 5 to the annular gap 7. Under the action of gas, the material moves into the transport pipeline 4. After collecting a certain portion of the material-spool 9, the valve 9 moves to the middle position. At the same time, the maternal is transported through pipeline-4 to its destination by the gas flow passing into pipeline 4 from pipeline 5 through the combined openings 13 of spool 9 and 12 of pipeline 4. After the end of transportation, the spool is lowered to the lower position, blocking the compressed supply pipe 5 with its upper part gas. Then the cycle is repeated. The feeder allows you to expand the technological capabilities of the device by providing a metered supply of material. 3 il.

i The invention relates to a pneumatic supply of bulk materials and to be used, for example, in fine metallurgy.

The aim of the invention is to solve technological possibilities by ensuring the dosed supply of material,

Fig. 1 shows the device; section j in Fig. 2 and 3 shows the position of the spool.

Chamber feeder contains a container i with a lid 2, in which holes 3 are made, In tank 1 there is a vertical transport pipeline 4 and pipeline 5 for supplying compressed gas. The transport pipeline .4. Is centrifugally enclosed by a cylindrical casing 6 with an annular gap 7 between W1, the lower part of the casing 6 is open and equipped with a movable nozzle 8, the annular gap 7 is connected to the compressed gas supply pipe 5, a spool is placed 9, Spool 9 is a stepped cylinder with an upper part of a larger diameter, seals the transport lines 4 with vertical displaceability along it, and overlaps the annular gap 7 with its upper part. Totic movement of the Ototika 9 is carried out, for example, with the help of rods 1.0, fixed on the spool 9 and spring-loaded with springs 11 relative to the cover 2. The rods 10 can be driven, for example, by means of a cam mechanism. versti 12, the overlap ate with the inner surface of the spool 9. In the upper part of the spool 9 there are radial holes 13, which, when combined with the openings 12 of the transport pipeline 4, communicate its cavity with the compressed supply pipe gas,

Chamber feeder works as follows

The powder material is poured into the container 1 through the openings 3 in the lid 2. The spool 9 is in the upper position (Fig. 1), the openings 12 are blocked by the spool 9. The material is carried away by the flow of gas coming through the pipeline 5 and the annular gap p 7 In the transport pipeline 4, the capacity of the material intake is controlled by moving the nozzle 8 along the casing 6. After the required dose of material has been received, the spool 9 moves to the middle position (FIG. 2) in which the radial holes 1-sh 13 of the zolonika 9 are aligned with the radial mi holes 12 of the conveying line 4 and with the compressed gas supply conduit 5. At the same time, the dosing of the material is completed, and the post: the material that is bled into the pipe 4 is transported by a stream of compressed gas passing through the aligned holes 12 and 13. along the transport line 4 to the destination. . At the end of the material transportation, the spool 9 moves to the lower position (Fig. 3) and overlaps with its
