[0034] The working principle of the present invention is:

[0035] The present invention relates to a rotary air cooling device. The device can add moist and high-temperature powdered materials through a hopper 5. After that, the hopper 5 is isolated by an electromagnetic valve, and the connecting cylinder 7 is driven to rotate by clicking, so that the materials are turned over. At this time, the air pump is started to inhale, and the gas enters from the right end sleeve. The diameter of the right end of the end sleeve is small, so that the turbine is blown by the high-speed flowing air, and then the fan blades 42 and the magnetic ring are driven to rotate. Through magnetic attraction, the annular fan blades 20 are rotated synchronously with the transmission shaft. The fan blades and the annular fan blades 20 are also rotated by the wind, and the materials on the right side walls of the large ring baffle 37 and the small ring baffle 40 can be hung down to ensure air circulation. At this time, the materials are rotated in the connecting cylinder. When the material is moving, due to the inclination of the connecting cylinder, the material will fall to the right, which is opposite to the air flow direction, and the material will continue to roll, with a large contact area with the air. Small particles of material will fall into the space between the inner net and the connecting cylinder through the gap in the inner net, so that the material is divided into two parts and blown for cooling and dehumidification, further ensuring that the material is in full contact with the air. When rolling, the stabilizing frame performs rolling limit and supports and limits the position through the ball bearings to ensure the rotation stability of the device. The air carrying powdery material enters the separator, separates the small amount of fine material carried from the air, and falls from the separator. The exhaust gas will pass through the filter bag to ensure that the exhaust gas of the device is clean, avoid material waste, and be cleaner and more economical.

[0036] The structure of the present invention is reasonable, and the device is equipped with a reasonable and stable support frame to ensure the stability of the device in use. The tilting and rolling structure, plus the layered structure, improves the sufficiency of the contact between the material and the flowing air inside the equipment. By fully utilizing the flowing air and through unpowered drive, the internal material adhesion is avoided, the air fluidity of the device is improved, and it is equipped with multi-stage solid-gas separation to ensure the cleanliness of the exhaust gas, avoid material waste, and has strong practicality.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
