Description

In an apparatus for cooling, drying, washing and the like processing of bulk materials, a drum with a horizontal geometric axis of rotation, divided perpendicular to this axis by a partition into two compartments with spiral partitions forming passages, and the direction of the stroke in one compartment is opposite to the direction in the other; the use of the proposed apparatus is intended to increase the path of the material and to improve the use of the processing medium (air, steam, water, etc.).

In the schematic drawing of FIG. } depicts a longitudinal section of the apparatus to the drum according to the DEGE of FIG. 2; FIG. 2-section on AB of FIG. 1, and FIG. 3-section of VG FIG. one.

The apparatus for cooling, drying, rinsing and the like processing of bulk materials consists of a drum enclosed in a casing 1 and divided into two compartments by a partition 21, inside of which is placed along a spiral partition, forming a spiral course 2, 5, 6, 7, and in the other - 8, 9, 10, 3. The number of pairs of moves can be increased and more than two, depending on the purpose

apparatus. A conduit 16 for supplying the material to be processed is connected to a receiver 4; the latter has a message with a spiral stroke 2, 5, 6, 7. The spiral turns of both compartments communicate through the extreme mx 7, 8, which together form a space 7, 8; the latter has an inclined plane in the lower part to facilitate the transfer of material from one spiral path to another.

The last turn of the spiral stroke 8, 9, 10, 3 is connected to the outlet 11, through channel 12, connected to the distribution mechanism 13. The socket 15 serves to admit medium acting on the material (air, steam, water, etc.). The ribs 19 are designed to pour material, and the peephole 20 is for observing the operation of the apparatus. By means of rollers 14 connected in a suitable manner to the gear, the drum is driven into rotation.

The arrows in the drawing show the passage of material that moves in the drum from the center to the circumference along the revolutions of the first helix, and then along the revolutions of the second helix goes from the circumference to the exit point of the apparatus. An exposure medium (steam, water) passes to meet the movement of the material and, at the beginning of the material being processed into the apparatus, can be further diverted for appropriate use, for example, into the funnel 17 and the head of the rotary kiln 18 attached to it to use heated air. in the case of cooling material.

It betrays the invention.

1. An apparatus for cooling, drying, rinsing and the like processing of bulk materials, characterized in that the drum forming it, having a horizontal geometric axis of rotation, is divided by a partition perpendicular to this axis into two compartments, each of which has a spiral aa partition, which goes in one compartment in the opposite direction than the other, the image in the first (from the entrance)

the separation is spiral 2, 3, 6, 7, and in the other 8, 9, 10, 3, with extreme turns 7 and 8 of both moves communicating with each other, turn 5 communicates with receiver 4, and the last turn 3 of the other helix by release 11, so that the material, having entered the receiver 4, first moves from the center to the circumference along the revolutions of the first helix, and then returns from the circumference to the center along the revolutions of the second helix, going to the exit of the apparatus2. the apparatus according to claim 1, characterized in that it has two or more partitions perpendicular to its geometrical axis and, accordingly, several pairs of spiral paths from the center to the circle and back.

3. In the apparatus according to PP. 1 and 2 the use of the nozzle 15 for the inlet of the medium acting on the material (air, steam, water, etc.),

4. In the apparatus according to PP. 1-3, use of ribs 19 for pouring material.
