Description

Technical Field

[0001] The utility model belongs to the technical field of emulsion explosive production, and more specifically relates to a novel static sensitization device for emulsion explosive. Background Art

[0002] The sensitization technology currently used in the sensitization process of domestic emulsion explosive production lines is a dynamic sensitizer. This uses an open dynamic mixer to thoroughly mix and sensitize the latex matrix and foaming agent before feeding the emulsion into a charging machine. For example, Chinese patent CN208532639U discloses a sensitization device for emulsion explosives. The device comprises a stirring body, a feed hopper disposed above the stirring body, and a feed pipe connected to the stirring body. Inside the feed hopper are a feed guide mechanism and a first cooling water pipe, and inside the feed pipe is a second cooling water pipe. The lower end of the feed pipe is movably connected to the stirring body, and a vibration mechanism is provided between the feed pipe and the stirring body. The feed guide mechanism guides the matrix, ensuring that it is dispersed into the feed hopper and flows smoothly downward. The first and second cooling water pipes effectively cool the matrix, improving sensitization efficiency. A vibration mechanism is provided between the feed pipe and the stirring body, generating a certain amount of vibration when the matrix enters the feed hopper, further ensuring the continuous sensitization process. This patent uses a dynamic stirring body to fully stir and sensitize the latex matrix and foaming agent.

[0003] However, dynamic sensitizers have the defects of complex structure, high energy consumption and low safety. In addition, the shear force during the dynamic sensitization process is large, which will destroy the original properties of the latex matrix, resulting in a decrease in the stability and explosive performance of the produced emulsion explosives.

[0033] See also Figure 1 Now, a novel static sensitization device for emulsion explosives provided in an embodiment of the present utility model is described.

[0034] In one embodiment of the present invention, a novel static sensitization device for emulsion explosives includes: a presensitized pipe 1, at least two first fixed retaining nails 2, a first sensitized core 3, a reinforced sensitized pipe 4, at least two second fixed retaining nails 5, and a second sensitized core 6. At least two first fixed retaining nails 2 are arranged on the outer wall of the presensitized pipe 1; one end of the first fixed retaining nail 2 penetrates into the interior of the presensitized pipe 1; the first sensitized core 3 is loaded into the presensitized pipe 1; the first sensitized core 3 is clamped between the two first fixed retaining nails 2; the reinforced sensitized pipe 4 is connected to the presensitized pipe 1; at least two second fixed retaining nails 5 are arranged on the outer wall of the reinforced sensitized pipe 4; one end of the second fixed retaining nail 5 penetrates into the interior of the reinforced sensitized pipe 4; the second sensitized core 6 is loaded into the reinforced sensitized pipe 4; the second sensitized core 6 is clamped between the two second fixed retaining nails 5; the shear force exerted by the second sensitized core 6 on the fluid is greater than the shear force exerted by the first sensitized core 3 on the fluid.

[0035] In one embodiment, the first sensitized core 3 is a spiral SK hybrid core, and the second sensitized core 6 is a cross SX hybrid core. The number of assembly sections of each type of core is adjusted according to production conditions.

[0036] When a new static sensitization device for emulsion explosives according to an embodiment of the present utility model is in use, the latex matrix and the foaming agent enter from one end of the pre-sensitization pipe 1, and the latex matrix and the foaming agent are pre-dispersed and mixed under the combined effects of the diversion, confluence and rotation of the first sensitizing core 3 in the pre-sensitization pipe 1; the mixture of the latex matrix and the foaming agent after pre-sensitization then enters the enhanced sensitization pipe 4, and under the combined effects of the diversion, confluence and rotation of the second sensitizing core 6 in the enhanced sensitization pipe 4, the latex matrix and the foaming agent are fully dispersed and mixed to achieve a good sensitized state.

[0037] A new type of static sensitization device for emulsion explosives in an embodiment of the present utility model preliminarily sensitizes the latex matrix and the foaming agent through a pre-sensitization pipe 1, and then re-sensitizes the mixture of the preliminarily sensitized latex matrix and the foaming agent through a reinforced sensitization pipe 4. After the preliminarily sensitized and re-sensitized, the foaming agent is fully and evenly dispersed in the latex matrix.

[0038] Since the shear force of the second sensitizing core 6 on the fluid is greater than the shear force of the first sensitizing core 3 on the fluid, if the first sensitizing core 3 and the second sensitizing core 6 are simultaneously loaded into the same sensitizing pipe, the pressure of the mixture of the latex matrix and the foaming agent in the sensitizing pipe will be too high, which will require a higher pressure bearing capacity of the sensitizing pipe and will be detrimental to the safe conduct of sensitization production. Therefore, the embodiment of the utility model performs step-by-step sensitization and mixing of the latex matrix and the foaming agent through two independent pre-sensitization pipes 1 and a reinforced sensitization pipe 4, which can achieve a good static dispersion effect while avoiding excessive pressure inside the device, thereby better ensuring the safe conduct of sensitization production.

[0039] A novel static sensitization device for emulsion explosives in an embodiment of the present invention is an energy-saving device without power or mechanical rotation. The production process is inherently safe, and the device has a simple structure, low energy consumption, and high safety. It can well protect the original properties of the latex matrix and effectively improve the storage stability and explosive performance of the emulsion explosive.

[0040] Furthermore, the presensitized pipe 1 of this embodiment is a double-layer jacketed pipe, and the presensitized pipe 1 is provided with a first heat exchange channel 7 and a first heat exchange medium inlet 8 and a first heat exchange medium outlet 9 connected to the first heat exchange channel 7. When in use, the first heat exchange channel 7 can be filled with liquid or gas of appropriate temperature as the heat exchange medium to adjust the temperature of the latex matrix and the foaming agent in the presensitized pipe 1, so that a better sensitization effect can be achieved at a suitable sensitization temperature.

[0041] Furthermore, the enhanced sensitization pipe 4 of this embodiment is a double-jacketed pipe, and is provided with a second heat exchange channel 10, and a second heat exchange medium inlet 11 and a second heat exchange medium outlet 12 connected to the second heat exchange channel 10. During use, the second heat exchange channel 10 can be filled with a liquid or gas at an appropriate temperature as a heat exchange medium to regulate the temperature of the latex matrix and foaming agent in the enhanced sensitization pipe 4, so that they can achieve a better sensitization effect at an appropriate sensitization temperature.

[0042] Furthermore, in this embodiment, the two ends of the pre-sensitized pipe 1 are connected to a first connecting flange 13, and the two ends of the reinforced sensitized pipe 4 are connected to a second connecting flange 14. The pre-sensitized pipe 1 and the reinforced sensitized pipe 4 are connected as a whole through the first connecting flange 13 and the second connecting flange 14. Specifically, the first connecting flange 13 and the second connecting flange 14 are connected as a whole by fastening screws.

[0043] Furthermore, the pre-sensitization pipe 1 of this embodiment is connected to a first pressure gauge 15, which is provided at the front end of the first sensitizing core 3. The front end of this embodiment refers to the upstream of the fluid flow direction, that is, before the latex matrix and the foaming agent are sheared and mixed by the first sensitizing core 3, the pressure of the mixture of the latex matrix and the foaming agent in the pre-sensitization pipe 1 must be detected to ensure that the pressure of the mixture of the latex matrix and the foaming agent is appropriate and to ensure the normal progress of static sensitization.

[0044] Furthermore, the enhanced sensitization pipe 4 of this embodiment is connected to a second pressure gauge 16, which is provided at the rear end of the second sensitization core 6. The rear end of this embodiment refers to the downstream of the fluid flow direction, that is, after the latex matrix and the foaming agent are sheared and mixed by the second sensitization core 6, it is necessary to detect the pressure of the mixture of the latex matrix and the foaming agent in the enhanced sensitization pipe 4 to ensure that the pressure of the mixture of the latex matrix and the foaming agent is appropriate and to ensure the normal progress of static sensitization.

[0045] Furthermore, a grounding wire 17 is connected between the first connecting flange 13 and the second connecting flange 14 of this embodiment. The safe operation of the device is ensured by providing the grounding wire 17. Furthermore, the grounding wire 17 of this embodiment can be any one of a copper core wire, an aluminum bar, or a stainless steel bar.

[0046] Furthermore, the first fixing retaining nail 2 of this embodiment is threadedly connected to the pre-sensitized pipe 1, and the second fixing retaining nail 5 is threadedly connected to the reinforced sensitized pipe 4. The detachable threaded connection facilitates the loading and fixing of the first sensitized core 3 and the second sensitized core 6.

[0047] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
