Problems solved by technology

Compared with the traditional cooling method, the above-mentioned technical solution has improved cooling effect, and the former has better effect; but at the same time, the above-mentioned technologies all adopt the method of directly passing cooling water inside the rotating shaft, and the cooling water flows from the beginning to the end of the rotating shaft. At the end, there is no interruption in the middle. Although this cooling method increases the contact surface between the material and the cooling water, it can improve the cooling effect, but the water flow at one time is relatively large. In this case, if the circulation speed of the cooling water is increased, that is, the unit time Internal water consumption increases, energy consumption increases, the utilization rate of cooling water is low, and environmental protection benefits are poor; if the circulation speed of cooling water is reduced, that is, the water consumption per unit time is reduced, the cooling speed of materials will be reduced and the cooling effect will be affected

Abstract

The invention provides a cooling and conveying device, and belongs to the technical field of conveying devices. The cooling and conveying device comprises a tank, a spindle, a driving mechanism, a feed inlet, a discharge outlet and a cooling mechanism. Advancing blades are intermittently arranged on the spindle and comprise cavity matrixes and spiral blades, the spiral blades are arranged on the cavity matrixes, the cooling mechanism comprises a water inlet pipe, communicating pipes and a water outlet pipe, the water inlet pipe, the communicating pipes and the water outlet pipe are arranged in the spindle, and the water inlet pipe, the cavity matrixes and the water outlet pipe are sequentially communicated with one another via the communicating pipes. The cooling and conveying device has the advantages that the cooling and conveying device is novel in structure and reasonable in design and can be applied to mixing, conveying and cooling expanded ammonium nitrate explosive, the expanded ammonium nitrate explosive can be sufficiently mixed, products are good in free-running property and stable in quality, and good cooling effects can be realized.

Description

technical field [0001] The invention belongs to the technical field of conveying devices, and in particular relates to a cooling conveying device. Background technique [0002] The main raw material of industrial explosives is ammonium nitrate, which is prepared by drying and crystallizing ammonium nitrate and other materials through process proportioning and dissolving under the action of surfactants. It is widely used because of its simple operation, relatively loose process conditions, low energy consumption, large production capacity, and stable and reliable product quality. The main problem of powdery explosives in the prior art is that due to the high temperature in the preparation process, the mixed solution before crystallization is at 130°C to 135°C, and the semi-finished product after crystallization is sent to the cold medicine at a temperature of about 90°C. Since the powdery explosive components contain wood flour and other elemental substances, if the mixing i...
