Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange cooling, in particular to a powder material cooling device. Background Art

[0002] At present, in the cement production process, the temperature of cement largely determines the suitability (fluidity) of cement products. When the temperature of cement out of the mill is higher than 90°C, the gypsum that produces a retarding effect in the cement ingredients is very likely to dehydrate. As a result, the product suitability (fluidity) is poor, causing great trouble to the construction of concrete projects. If the water reducer is added, its suitability can be improved, but the construction cost will continue to increase.

[0003] The reason for the high temperature of cement out of the mill is that the temperature of clinker, which accounts for the largest proportion of the main ingredients of cement, is too high. At present, the clinker temperature of most cement companies is above 100°C, especially in summer. Spraying water inside the cement mill to cool it down will increase the moisture content of the product and affect the quality. Spraying water on the outside of the cylinder to cool it down has little effect and affects the on-site environment. Utility Model Content

[0004] The purpose of the utility model is to provide a powder material cooling device, in which the powder material is poured into the inside of the feed hopper and supported by the chute canvas, and the fan introduces external gas and circulates it to the lower end position to provide the conveying power of the air to complete the circulation. During the circulation process, the cooling pipe is used to reduce the temperature, thereby increasing the cooling effect and achieving the cooling effect.

[0005] To achieve the above object, a powder material cooling device is provided, comprising: powder material, a first section chute, a second section chute and a cooling tower, wherein one side of the first section chute is fixedly connected to the second section chute, the bottom ends of the first section chute and the second section chute are both provided with gas flow grooves, the first section chute and the second section chute are both fixedly connected to the lower middle parts with chute canvases, and the top of the chute canvases is provided with powder material;

[0006] A water tank is fixedly connected to the top between the first section chute and the second section chute, and water pumps are fixedly connected to both sides of the top of the water tank. The output ends of the two water pumps are flange-connected to the cooling water pipe of the first section chute and the cooling water pipe of the second section chute respectively.

[0007] According to the powder material cooling device, an air circulation pipe is fixedly connected to the bottom of one end of the gas circulation groove, and a fan is flange-connected to one end of the air circulation pipe.

[0008] According to the powder material cooling device, a feed hopper is fixedly connected to one end of the top of the second section chute.
