Abstract
The invention discloses a cooling spiral conveyor for powdery explosives, and belongs to a powdery explosive production device. The cooling spiral conveyor comprises a spiral body, a spiral groove, a power device, a transmission device, a combined water seal device, a feed device, a discharge device, a sealing cover plate and the like. Spiral blades of the cooling spiral conveyor are designed to be interlayers. A mandrel is in the form of a steel pipe. The spiral groove is also designed to be an interlayer. Inner cavities of the interlayer spiral blades, an inner cavity of the mandrel and an inner cavity of the interlayer spiral groove are communicated to form a cooling liquid circulation channel. When the explosives are conveyed, circulating cooling is conducted by leading in cooling liquid. A spiral is installed at a certain inclination angle. In this way, the explosives are effectively cooled while being conveyed to an inlet of a bundling press, low-temperature explosive charging is achieved, the hygroscopicity of the explosives is greatly reduced, the product quality is improved, and the storage period of the explosives is prolonged.
