Description

Technical Field

[0001] The utility model belongs to the technical field of emulsion explosive production, and specifically relates to a drying device for explosive production. Background Technique

[0002] Emulsion explosive is a water-in-oil emulsion explosive formed by uniformly dispersing micro-droplets of an oxidizer salt aqueous solution in an oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres with the help of an emulsifier. Emulsion explosive has good water resistance, good explosion performance, good mechanical and safety properties. During the production process of emulsion explosive, it is necessary to cool the explosive rolls. The existing cooling method is to transport the explosive rolls to a water tank for cooling through a conveyor belt, and then use a drying device to dry the cooled explosive rolls and carry out the next process. During the process of drying the emulsion explosive by the existing drying device using air drying, a large wind force will cause the emulsion explosive on the conveyor belt to be scattered and blown off, which is likely to cause safety accidents. At the same time, the water stains remaining on the conveyor belt will re-wet the dried explosive rolls, reducing the drying effect of the explosive rolls, affecting the subsequent processes, and resulting in a reduction in the performance of the emulsion explosive. Therefore, it is necessary to design a drying device for explosive production that can prevent the explosive rolls from being blown off the conveyor belt and at the same time prevent the water stains on the conveyor belt from re-wetting the explosive rolls. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a drying device for explosive production that can prevent the explosive rolls from being blown off the conveyor belt and at the same time prevent the water stains on the conveyor belt from re-wetting the explosive rolls.

[0004] To solve the above technical problems, the technical solution of the utility model is: a drying device for explosive production, including a drying box and a conveyor belt. The left and right sides of the drying box are provided with reserved openings, and the conveyor belt passes through the reserved openings and penetrates through the lower part of the drying box. The two ends of the rotating roller of the conveyor belt are rotatably connected to the upper ends of the supports. The front and rear sides of the drying box are fixedly connected with legs. The inner top of the drying box is fixedly connected with a blowing mechanism. The inner bottom of the drying box is fixedly connected with a liquid collecting tank. The bottom of the liquid collecting tank is provided with a drainage pipeline. The lower part of the inner wall of the drying box is fixedly connected with an anti-collision buffer layer. A number of water drainage holes are provided on the conveyor belt.

[0005] Further, the blowing mechanism includes a blower, an air disc, and air outlets. The top of the air outlet is communicated with the bottom of the air disc. The top of the air disc is fixedly connected with the inner top wall of the drying box. The output end of the blower is communicated with the air disc through an air supply pipeline.

[0006] Further, the air outlets are arranged vertically downward, and a filter screen is provided on the input end of the blower.

[0007] Further, a plurality of funnel-shaped circular depressions are formed on the upper surface of the conveyor belt, and the water drainage holes are formed at the centers of each circular depression.

[0008] The utility model has the following advantages compared with the prior art:

[0009] 1. By arranging the anti-collision buffer layers on both sides of the conveyor belt, the utility model can buffer and protect the blown explosive cartridges during the drying process, prevent the explosive cartridges on the conveyor belt from being scattered and blown off due to strong wind, and avoid safety accidents; by arranging the water drainage holes on the conveyor belt, the water droplets attached and carried out on the conveyor belt can fall into the liquid collecting tank through the water drainage holes and be re-drained into the water pool, reducing the residual water droplets on the conveyor belt and avoiding the re-wetting of the dried explosive cartridges by the water droplets, effectively preventing the performance reduction of the emulsion explosive.

[0010] 2. Circular depressions are formed around the water drainage holes arranged on the conveyor belt of the utility model, so that the water droplets on the conveyor belt gather along the circular depressions and enter the water drainage holes, improving the speed of removing the water droplets on the conveyor belt and further ensuring the drying efficiency of the explosive cartridges.
