Abstract

The invention relates to devices for reloading bulk materials and can be used in the chemical, construction industry and other sectors of the national economy. The purpose of the invention is to improve the uniformity of the feed material. Bulk material is fed through pipe 2 to housing 1. Continuously, a part of the material is passed through a circulation pipe 11 with a tangential outlet to the air-mixture separator. Next, the bulk material is transported by the screw through the discharge connection to the chamber 12, cut by the disc ripper 16 and the paddle feeder is fed to the consumer. The suction of dusty air is carried out by a fan 14. 1 sludge.

Description

The invention relates to continuous equipment for stabilizing the flow of bulk materials and can find application in the chemical, construction, medical industry and other sectors of the national economy, where stabilization of bulk density of bulk is necessary.

The purpose of the invention is to increase the uniformity of the supply of material.

The drawing shows a device, General view.

A device for reloading bulk materials contains a housing 1 with a loading nozzle 2 and a conical bottom 3 located in the last gas distribution grill 4, a horizontal screw 5. located in the housing and a side discharge nozzle 6 above the grill, and a blade feeder 7. mounted iodine with a discharge nozzle 6. In the upper part of the casing there is a separator of the material-air mixture, consisting of a cylindrical shell 8 located coaxially above it at a distance equal to 0.2 0.5 of the diameter of the cylindrical shell from loading nozzle, conical casing 9 and foam. foam on the last elastic curtain 10. When the ratio of the depth to diameter

0.5 the density of the material flow is maximum and at the same time it provides good fluidity in the hopper and the absence of stagnant zones. Moreover. The stropegvo contains a circular pipe II. one end tangentially communicated with a cylindrical shell 8. the other with a body cavity I in the area of the lower part of the bottom, a chamber 12 connected with an unloading pipe in the area of the outlet end of the screw and through a pipe 13 with a body cavity in its upper part, a fan 14 mounted on auger blade 15 and disk 16 rippers. locking device 17 and pneumatic transport device 18.

Ustroysgvo works as follows.

Bulk material is fed into the housing 1 through the loading pipe 2 in heat. In the bottom of housing I are all aeration devices. Air enters the recirculation loop, which consists of a gas distribution grill 4, a shut-off device I 7. pneumatic transport device 18, a pipe 11 and a separator of bulk material and air. Dusty air passing through the curtain 10 and the layer of material aerates it, thereby increasing the area of the moving material. A cyclone effect occurs. The material slides along the inner surface of the shell, and dusty air is discharged through the gap formed by the shell 8 and the casing 10. Thereby, the material is recycled in the volume of the housing I.

The material is discharged from the housing by the screw 5 through the loading pipe 6 into the chamber 12, from which air is taken out in the upper part of the housing through the pipe 5 of the wire 13 and the fan 14. The bulk material before entering the discharge pipe 6 is several pressure turns, then two blade rippers 15, and in the chamber there are two disk rippers 16. Rippers provide the gathering of the material. 10 On the screw shaft there are blades along a helical line that carry the bulk material in the axial direction, compacting it during movement, and the next blade and disk rippers cut it ₁₅ . At the exit of the chamber there is a blade feeder 7, which gives the final product of constant bulk density and accurate dosage. A decrease in the ratio less than 0.21) leads to a flare emission of dusty material, and an increase (more than 0.5D) leads to a greater resistance of the material in the housing above the separator, which reduces the efficiency of the material circulation process.

The angle of the cone of the casing is selected constructively (125 1401 ° from the conditions of normal descent from its surface.
