Description

Technical Field

[0001] This utility model relates to the field of explosives preparation, specifically to an explosives reaction device. Background Technology

[0002] Currently, the reaction process for explosives products is entirely carried out in a single reactor, involving mixing, heating, cooling, and heat preservation. The entire process takes place within a single reaction vessel, and existing reactors suffer from drawbacks such as small heat exchange area and low heat exchange efficiency. Therefore, it is necessary to improve production efficiency by modularizing and functionalizing the entire production process. Summary of the Invention

[0003] This invention addresses the technical problems of small heat exchange area and low heat exchange efficiency in existing batch reactors by providing a pyrotechnic reaction device. It can accelerate the material reaction process, and due to the increased surface area, it enables rapid heat exchange, greatly improving production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a pyrotechnic reaction device, including a mixing device, a spiral stirring rod installed inside the mixing device, the spiral stirring rod being connected to a motor, the top of the mixing device being connected to a liquid material inlet and a solid material inlet; the bottom of the mixing device being connected to a heat exchange device through a pipeline, the heat exchange device including multiple heat exchange units connected in parallel through pipelines, each heat exchange unit including a heat exchange inner liner and a heat exchange shell, a cavity for containing heat exchange medium being left between the heat exchange inner liner and the heat exchange shell, the lower part of the heat exchange shell having a heat exchange medium inlet and the upper part having a heat exchange medium outlet, the bottom of the heat exchange inner liner being connected to a discharge port extending out of the heat exchange shell; each heat exchange unit having a feed port at its upper end, all feed ports being connected to branch pipelines, the bottom of the mixing device being connected to a main pipeline, the main pipeline being connected to each branch pipeline.

[0005] Working Principle and Process: The material first enters the mixing device, where it is stirred and mixed evenly. Then, it enters the heat exchange device for heating, cooling, and heat preservation before being discharged. Heat exchange medium is continuously injected through the inlet and outlet to achieve the heating, cooling, and heat preservation processes. For example, if the ratio of material mixing time to heating / cooling / heat preservation time is 1:4, the first batch of mixed material is fed into heat exchange unit #1, where it undergoes the heating, cooling, and heat preservation processes. After the mixing device discharges the material, the second batch is fed into heat exchange unit #2, and so on, with the third and fourth batches being mixed and fed into heat exchange units #3 and #4. After one cycle, the mixing device continues feeding material. Once mixing is complete, heat exchange unit #1 discharges the material, and the process is repeated. This reduces the previous 5-hour batch production time to one batch per hour after 5 hours, significantly improving production efficiency.

[0006] Furthermore, the mixing device 1 and the heat exchange device 5 are all made of 316L stainless steel, and the valves and motors used are explosion-proof.

[0007] Furthermore, valves are installed on both the main pipeline and each branch pipeline.

[0008] Furthermore, the heat exchange medium inlet and heat exchange medium outlet are located on opposite sides of the heat exchange shell.

[0009] Furthermore, the heat exchange unit is cylindrical.

[0010] Furthermore, the heat exchange device includes four heat exchange units connected in parallel via pipelines.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention reduces the problems of high heat exchange energy loss and low heat exchange efficiency in the production of explosives, while greatly improving production efficiency. This invention is applicable to products in the production process of explosives involving mixing, heating, cooling, and heat preservation steps.

[0013] This utility model of explosive reaction device modularizes and functionalizes the entire production process, changes the equipment structure, increases the heat exchange area, improves heat exchange efficiency, and automatically adds the number of heat exchange devices in parallel according to the reaction time of each process, thereby greatly improving the production efficiency of explosives.

[0017] The present invention will be further described below with reference to specific embodiments. Example 1

[0018] like Figure 1As shown, a pyrotechnic reaction device includes a mixing device 1, with a spiral stirring rod 2 installed inside the mixing device 1. The spiral stirring rod 2 is connected to a motor. The top of the mixing device 1 is connected to a liquid material inlet 3 and a solid material inlet 4. The bottom of the mixing device 1 is connected to a heat exchange device via a pipeline. The heat exchange device includes multiple heat exchange units connected in parallel via pipelines (the number of heat exchange units is automatically added in parallel according to the reaction time of each process to achieve the highest production efficiency). Each heat exchange unit includes a heat exchange inner liner 5 and a heat exchange shell 6. A cavity for containing heat exchange medium is left between the heat exchange inner liner 5 and the heat exchange shell 6. The lower part of the heat exchange shell 6 has a heat exchange medium inlet 7, and the upper part has a heat exchange medium outlet 8. The bottom of the heat exchange inner liner 5 is connected to a discharge port 9 extending out of the heat exchange shell 6. Each heat exchange unit is provided with a feed port at its upper end. All feed ports are connected to branch pipelines. The bottom of the mixing device 1 is connected to a main pipeline, and the main pipeline is connected to each branch pipeline.

[0019] Furthermore, the mixing device 1 and the heat exchange device are all made of 316L stainless steel, and the valves and motors used are explosion-proof.

[0020] Furthermore, valves are installed on both the main pipeline and each branch pipeline.

[0021] Furthermore, the heat exchange medium inlet 7 and the heat exchange medium outlet 8 are located on both sides of the heat exchange shell 6, respectively.

[0022] Furthermore, the heat exchange unit is cylindrical, which increases the heat exchange area and can effectively reduce the time of the heating and cooling process.

[0023] Furthermore, the heat exchange device includes four heat exchange units connected in parallel via pipelines.

[0024] Furthermore, valves are installed on both the main pipeline and each branch pipeline.

[0025] Working Principle and Process: The material first enters the mixing device, where it is stirred and mixed evenly. Then, it enters the heat exchange device for heating, cooling, and heat preservation before being discharged. Heat exchange medium is continuously injected through the heat exchange medium inlet 7 and outlet 8 to achieve the heating, cooling, and heat preservation processes. If the time ratio of material mixing to heating / cooling / heat preservation is 1:4, the first batch of material is mixed and then placed into heat exchange unit #1, where it undergoes the heating, cooling, and heat preservation processes. After the mixing device discharges the material, the second batch is added to heat exchange unit #2, and so on, with the third and fourth batches mixed and placed into heat exchange units #3 and #4. After one cycle, the mixing device continues to add material. Once mixing is complete, heat exchange unit #1 completes the reaction and discharges the material. The material is then returned to heat exchange unit #1, and the above operation is repeated. This reduces the previous 5-hour batch output to one batch per hour after 5 hours, significantly improving production efficiency. The structure of the heat exchange device has been changed from a spherical shape to a cylindrical shape, increasing the heat exchange area and effectively reducing the time spent on heating and cooling processes.

[0026] This utility model of explosive reaction device modularizes and functionalizes the entire production process, changes the equipment structure, increases the heat exchange area, improves heat exchange efficiency, and automatically adds the number of heat exchange devices in parallel according to the reaction time of each process, thereby greatly improving the production efficiency of explosives.
