(54) VIBRATION FEEDER-DISPENSER

The invention relates to the field of vibration dosing of bulk materials.

A vibrating feeder is known, comprising a feeder feeder housing with a discharge chamber, a material sealing chamber with a loading nozzle and a partition wall with an adjustable damper and a vibrator ij.

Closest to the invention is a vibrating feeder-dispenser containing a sealing chamber with a material loading nozzle installed in the upper part, an unloading chamber whose upper part is connected to a gas outlet and the lower part communicates with a perforated cone nozzle connected to a smaller base with a nozzle material installed in the gas supply chamber with a gas inlet connection and communicated with the sealing chamber by a supply channel through a partition wall with a flap, and vibration ator The feeder dosing unit provides simultaneous dosing of the granulate material and the removal of L2J dust.

However, the lateral abutment of the material sealing chamber to the perforated tapered nozzle results in the granulate moving only over a part of the nozzle surface. Consequently, the purged gas, having experienced the resistance of the granulate layer, rushes mainly through the free part of the perforated packing, which leads to a high gas consumption and a decrease in the amount of dust removed.

The purpose of the invention is to increase the efficiency of dust removal.

20 parts with a material loading nozzle, an unloading chamber, the upper part of which is connected to the gas inlet fitting 6, and the lower part communicates with a perforated conical nozzle connected with a smaller base to the material outlet nozzle, installed in the gas supplying nozzle with a gas inlet and connected to the sealing chamber 30 through a dividing partition, and a vibrator, a seal on the chamber is placed concentrically with the discharge chamber, and the dividing partition is cylindrical and installed The outside of the perforated tapered nozzle with an annular gap relative to the discharge chamber. In addition, the partition is equipped with mechanisms of translational movement and part of it is made in the form of bellows. The drawing shows a vibrating feeder-dispenser, right side section. The vibrating feeder contains a sealing chamber 1 installed on elastic supports 2 and connected to the vibrator 3, a perforated tapered nozzle 4, the smaller base of which is connected to the nozzle 5 of the material-granule outlet. The nozzle 4 is installed in the gas supplying chamber (b, in the lower part of which there is a connector (supply of gas (inert or air)). Outside the perforated tapered nozzle 4, a separating cylindrical partition 8 is installed, part of which is made in the form of a bellows 9, the cylindrical separating partition is equipped with 10 mechanical mechanisms of their translational movement, made, for example, in the form of screws-nuts 11 and springs 12. Cylindrical the partition 9 is installed with an annular gap relative to the unloading chamber 13,; communicated with the sealing chamber 1 by the feeding channel 14. The upper part of the unloading chamber 13 is designed as a dome 15 with a 16 o fitting the lead. gas. In the upper part of the sealing chamber 1, mounted concentrically with the discharge chambers 13, a nozzle 17 for supplying material, for example, a granulate, is mounted. The nozzles 17 and 5 are connected to the sealing chamber 1 and the perforated conical nozzle 4 by means of flexible connecting elements 18. The exhaust chamber 13 separates the gap between the sealing chamber 1 and the cylindrical partition wall B into two cavities 19 and 20 communicating with each other in the lower part channel 14. During the operation of the feeder-dispenser, the bulk material (granules) flows through the material supply nozzle 17 into the sealing chamber 1 and is poured over the dome-15 into the cavity 19. The vibration of the sealing chamber 1 and All the chambers located in it are provided with elastic supports 2 and a vibrator 3. Gas (inert or air) is supplied through the gas supply nozzle 7 into the gas supply chamber 6. Passing the perforated cone nozzle 4, the gas is removed through the gas outlet nozzle 16 in the dome 15. Due to vibration, the bulk material filling the annular cavity 19 between the sealing chamber 1 and 13 passes through the feed channel 14 and fills the annular cavity 20, rising to the edge of the partition wall 8. In this position, the device is in operation. At the same time, the bulk material is poured over the edge of the partition 8, and moving along the surface of the perforated cone nozzle 4, forms a layer pierced by gas jets, which carry away dust and water vapor, which is then removed from under the dome 15 through fitting 16. Cleaned the material is removed through the nozzle 5 and is recycled. The performance of the device is regulated by changing the height of the dividing cylindrical partition 8, which is achieved by the mechanisms of translational movement of the screw-nut, g and 10, connected to the dividing partition 8; these same mechanisms allow adjusting the position of the edge of the dividing partition to set it horizontally, how does the uniform distribution of the bulk material over the surface of the cone depend on it? The proposed feed feeder has all the positive properties of a known vibration feeder of a fnpoto type), namely, it dispenses bulk material simultaneously with dedusting and removal of water vapor. In comparison with the known device, the proposed feeder-dispenser ensures the uniformity of the product properties, the intensity of the removal of dust and water vapor at a much lower flow rate of the gaseous medium. With the same performance, the proposed device has much smaller dimensions. Claim 1. Vibrating feeder-dispenser, sealing with a material loading pipe installed in the upper part, unloading chamber, the upper part of which is connected to the gas outlet fitting, and the lower part communicates with a perforated conical nozzle connected with a smaller base to the material outlet pipe, installed in the gas supply chamber, with a gas inlet fitting and communicated with the sealing chamber by a feed channel through a partition wall, and a vibrator different In order to increase the efficiency of removing the dust fraction, the sealing chamber is placed concentrically with the discharge chamber, and the partition wall is cylindrical and installed outside the perforated tapered nozzle with an annular gap relative to the discharge. 2. A feeder-dispenser according to claim 1, characterized in that The town is equipped with translational mechanisms and part of it is made in the form of bellows.
