Description

I

FIELD OF THE INVENTION The invention relates to agricultural machine building, namely to coolers of bulk materials using the natural cold of the air.

The purpose of the invention is to preserve the quality of the material.

FIG. 1 shows the proposed cooler, a general view of FIG. A-A in FIG. one ; in fig. 3 shows a section BB in FIG. one.

The bulk materials cooler; alov includes case I, in the upper part of which a receiving chamber 2 is formed, and underneath the proposed loading level there is a working chamber 3, in the walls of which there are blinds 4. Along the axis of the working chamber 3 there is an air receiver with blinds 6 and the lid 7. The air collector 5 is connected to the diffuser 8 The cooler contains an unloading device 9. In the upper part the body 1 is installed. With the formation of one or several air channel 10 one or more partitions 11, the upper edge of each of which is located in the receiving The second 2 is higher than the proposed material loading level, the lower edge is in the cavity of the air collector 5 under the lid 7. The receiving chamber 2 is equipped with a device to maintain the cooled material level: a containing flap 12 and sensors 13 and 14, respectively, of the upper and lower levels of material. The cavity of the air collector 5 through the window 15 communicates with the diffuser 8 on the suction line of the fan,

The total area of the transverse section of the channels 10 is equal to

V is the air velocity in the channel, m / s.

During the operation of the cooler bulk materials, for example, pellets, hot granules after the press continuously fill the working chamber 3 and part of the receiving chamber 2. At the same time, through a layer of grains in the chamber 3, a powerful stream of atmospheric air generated by the fan (not shown) cools granules and reduces their moisture. Since the hack of the upper part of the receiving chamber 2 is communicated via channels 0 to the air collector 5, the air is sucked out by the receiving chamber 2 "

Atmospheric air, sucked through the filling neck, penetrates into the hot surface of the granules located in the cooler's receiving chamber 2, where they are superficially cooled, and the heated air, as lighter, rises up and through the channel 10 is sucked through the window 15 into the diffuser 8 and is released to the atmosphere.

Pellets having a high temperature and high humidity form a large amount of steam, which, together with the heated air, is removed from the receiving chamber 2,

As the receiving chamber 2 is filled, the granules begin to press on the - valve 12, which, turning, presses the sensor with its lever

13 of the upper level, with the help of which the unloading device 9 is turned on, where the granules are discharged and fed for further processing. The level of granules in the receiving chamber 2 sets the flap 12, which, under the action of its own weight, returns to its original position and presses the lever on the sensor

14 lower level, which disables the unloading device 9.

The use of the present invention due to the reduction of loss of potassium in the receiving chamber allows preserving the quality of the cooled material.
