Abstract

The invention relates to the pneumatic transport of bulk materials and can be used in the construction, chemical, food and other sectors of the national economy. The purpose of the invention is to increase reliability and performance. The chamber feeder consists of a housing 1 with a conical lower part 2 and a loading neck 3. The discharge pipe 5 with a cylindrical intake part 6 is mounted in the case. The conical reflector 7 is made of plates 8 and 9 forming a two-way spiral mounted on the intake part 6. Between the outermost points of the plates 8 and 9 and the inner surface of the conical part of the housing 2 there is a constant gap. The feeder works as follows. After the material is loaded into the housing 1, compressed air is fed into the feeder through the feed neck 3. Under the action of air pressure in the feeder, the material moves to the intake part 6 of the discharge pipe 5. When the material passes through a two-way spiral of the plates 8 and 9 of the reflector 7, the material mixes and loosens. Then the material passes to the intake part 6 and further along the discharge pipe 5 is transported to its destination. 3 il. with (Q (L with about with 4

Description

one

The invention relates to the pneumatic transport of bulk materials and can be used in the construction industry, for example for transporting cement, lime, gypsum, etc.

The aim of the invention is to increase reliability and performance.

FIG. 1 schematically shows a feeder, a general view; in fig. 2 — node I in FIG. one; in fig. 3 is a section A-A in FIG. one.

The feeder consists of a housing 1 (FIG. 1) with a tapered conical part 2 tapering downwards, in the upper part of which there is a loading neck 3, a nozzle 4 for

material in the lower part of the feeder, which prevents diametrical clamping of the material and compaction in the suction zone.

When the air mixture passes through the spiral plates 8 and 9, an additional impulse of force is generated, which acts along the direction of the plates, which is carried along by the adjacent layers of material.

This prevents the formation of caking foci in the area of the intake part 6 and arching, which is an additional turbulizer for the movement of the mixture along the reflector. The presence of a constant gap between the plates and the inner

The intake part 6 is fixed spiral plates 8 and 9; Chamber feeder pneumatic transceiver (Fig. 3). At the same time, the conical reflector of the 20th installation, comprising the case with the loading 7, is installed with the bottom facing downwards with the formation of a constant gap between the outermost points of the plates 8 and 9 and the inner surface of the conical lower part 2 of the housing 1. The feeder works as follows. Through the neck 3, the body 1 is loaded in a known manner. After loading and closing the neck 3, open the pipe 4 of the compressed air supply, under the action of which the material enters the discharge pipe 5. At the same time, the material prone to the formation of caking and lumps moves through spiral plates. Due to the installation of plates 8 and 9 with the formation of a two-way helix, as the material moves, there will be a displacement of the tapered part and a tapered cone tapering downward; and made of plates installed at an angle to the axis of the discharge pipe, characterized in that, in order to increase reliability and productivity ti, conical reflector is fixed to a cylindrical chamfer part top down to form a constant gap between the outermost points of the plates and the inner surface of the conical lower portion of the housing, wherein the plates are mounted to form a double helix. thirty 35 10314 2 material in the lower part of the feeder, which will prevent diametrical clamping of the material and compaction in the suction zone.
