(54) COOLER MATERIALS COOLER

one

The avoidance refers to coolers of bulk materials, mainly feed pellets and briquettes.

Known cooler bulk materials, including having a perforated wall tank with installed in it with a gap of perforated distribution pipe that communicates with the discharge pipe of the fan 1.

During operation of the specified cooler, there is no uniform cooling of the material loaded into the gap between the tank and the distribution pipe, which is inversely flowed through the air flowing through the holes of the latter.

The closest in technical essence to the present invention is a bulk materials cooler, including a vertical column loaded with material to be loaded on top, having in the lower part a main louvre surface enclosed in a casing for air intake with a branch pipe fitted with a flap, installed inside the column a main chamber with a louvered surface located at the level of the said louvre surface, and a fan with suction

pipe located at the top of the column 2.

The disadvantage of this cooler is that it does not provide intensive cooling of the material.

The purpose of the invention is to intensify the process of cooling the material.

This is achieved by the fact that the upper part of the column is made with an additional louvered surface and is equipped with a casing for sucking air, which is enclosed last, connected to the suction side of the fan, and an additional chamber with a louvered surface located at the level of the additional louvered surface of the column, the main and additional camera 15 is communicated with the corresponding covers.

In addition, the flap in the nozzle is installed with the possibility of its alternate opening and closing.

FIG. 1 schematically shows a cooler of bulk materials, mainly feed pellets and briquettes, a longitudinal section; in fig. 2 - the same, side view; in fig. 3 is the same, section A-A in FIG. one; in fig. 4 is the same, section BB in FIG. one

The cooler includes loaded material through the opening 1 vertical column 2, having in the lower part the main louvre surface 3, enclosed in a casing 4 for air intake with a branch pipe 5 equipped with a damper 6. Inside the column 2 there is a main chamber 7 with a louvre surface 8 located at the level main louvre surface 3. The upper part of the column is made with an additional louvre surface 9 and is equipped with a casing 10 for suction of air, which is enclosed last, connected to the suction nozzle 11 of the fan 12, and an additional chamber 13 with a louver surface 14 located at the level of the additional louver surface 9 of the column. The main chamber 7 communicates with the casing 4 through an opening 15, the additional camera 13 communicates with the casing 10 through an opening 16. A damper 6 is installed in the branch pipe 5 with the possibility of its alternate opening and closing and functions as a pulsator of air supplied to the column. Under the column is placed the discharge device 17, controlled from the sensor 18 of the level of material in the column.

The cooler works as follows.

Due to the thrust generated by the fan 12, the cooling air enters the inside of the column 2 through the opening 1, as well as through the nozzle 5, the opening 15 of the main chamber 7 and the louvered surfaces 3 and 8. In the upper part of the column the direction of movement of the loaded material and air coincide, in the lower part of the column the air moves towards the material. The air is removed from the column through the louvered surfaces 9 and 14, the hole 16 and the suction nozzle 11. During the cooling process, air penetrates the material in horizontal and vertical directions with pulsating flows created by turning the flap 6 in the nozzle 5. Due to this cooling effect, the cooling process is significantly intensified. granules and briquettes.

Claims (2)

1. Cooler bulk materials, mainly feed pellets and briquettes, including a loading vertical material with a vertical column, having in the lower part a main louvre surface encased in an air intake casing with a branch pipe, fitted with a damper, a main chamber with a louvre surface located at the level of the said louvre surface installed inside the column, placed in the upper part of the column, characterized in that, in order to intensify the process of cooling the material, the upper part of the column is made with additional louvers th surface and the casing is provided with an air suction which is contained the latter connected to the suction side of the fan, and a second camera with louvered surface located at the level of the additional louver surface of the column, wherein the main and additional chamber communicated with the respective housings. 2.
