Description

Technical Field

[0001] The utility model relates to the technical fields of mineral resource development, civil blasting equipment and chemical process equipment, and in particular to a sensitization device for fully static emulsion explosives. Background Art

[0002] As the country's safety requirements for the production of civil explosives are increasingly strengthened, the production of emulsion explosives is developing in the direction of large-scale production, full static state, and unmanned (or less manned) operations. The key links of emulsion explosives, such as emulsion making and sensitization, have gradually changed from the previous mechanical dynamic emulsion making and sensitization to full static emulsion making and sensitization. In the sensitization link, the static sensitization device currently used is generally composed of a combination of multiple SK-type or SV-type sensitization units, that is, multiple sensitization units are connected in series, and the latex matrix, sensitizer, catalyst, etc. are mixed and dispersed through multiple series-connected sensitization units, relying on the mesh flow channel to change the flow direction of the fluid. The existing sensitization device is too long and has disadvantages such as large pressure loss, poor dispersion effect, uneven sensitization, and many large bubbles. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a sensitization device for fully static emulsion explosives which has a simple and compact structure and is uniformly mixed.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a sensitization device for fully static emulsion explosives, comprising a sensitization tube, one end of which is provided with a feed port, and the other end of which is provided with a discharge port, and a fluid dispersion component and at least one sensitization unit are sequentially provided between the feed port and the discharge port.

[0005] As a further improvement of the above technical solution: the sensitizing unit includes multiple groups of sensitizing components, and the sensitizing components include multiple sensitizing plates arranged in parallel. There is a gap between two adjacent sensitizing plates of the sensitizing components, and the sensitizing plates of two adjacent groups of the sensitizing components are arranged crosswise.

[0006] As a further improvement of the above technical solution: the sensitizing plates of two adjacent groups of the sensitizing components are arranged vertically.

[0007] As a further improvement of the above technical solution: the sensitizing plates of two adjacent groups of the sensitizing components are connected as one.

[0008] As a further improvement of the above technical solution: a flow guide tube is provided in the sensitizing tube, and the sensitizing unit is provided in the flow guide tube.

[0009] As a further improvement of the above technical solution: two sensitization units are provided in the guide tube.

[0010] As a further improvement of the above technical solution: the fluid dispersion component includes at least one fluid dispersion sheet.

[0011] As a further improvement of the above technical solution: a feed nozzle is provided at the feed port, the fluid dispersion component is provided in the feed nozzle, a feed throttling hole is provided at one end of the feed nozzle close to the sensitization unit, a discharge nozzle is provided at the discharge port, and a discharge throttling hole is provided in the discharge nozzle.

[0012] As a further improvement of the above technical solution: a hole retaining ring for fixing the fluid dispersion component is provided in the feed nozzle, and a hole retaining ring for fixing the feed nozzle is provided in the sensitizing tube.

[0013] As a further improvement of the above technical solution: connecting flanges are provided at both ends of the sensitizing tube.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The present invention discloses a fully static emulsion explosive sensitization device. By sequentially disposing a fluid dispersion assembly and a sensitizing unit between the feed and discharge ports of a sensitizing tube, the integrated sensitization device achieves a compact structure and avoids pressure loss of the mixed material due to excessive flow channels. The fluid dispersion assembly and multiple sensitizing units allow the mixed fluids of the latex matrix, sensitizer, catalyst, etc. to be dispersed and mixed multiple times within the sensitizing tube, improving sensitization uniformity.

[0016] 2. The utility model discloses a sensitization device for fully static emulsion explosives. Multiple sensitization plates are arranged at intervals and crosswise to form a sensitization unit with multiple sensitization holes inside. This allows the mixed fluid flowing through the sensitization unit to be dispersed more times, further improving the uniformity of fluid mixing and enhancing the sensitization effect.

[0017] 3. The utility model discloses a sensitization device for a fully static emulsion explosive, in which the sensitizing plates of two adjacent groups of sensitizing components are arranged vertically, which is beneficial to further enhance the sensitization effect of the sensitizing unit.

[0018] 4. The utility model discloses a sensitization device for a fully static emulsion explosive, in which the sensitization plates of two adjacent groups of sensitization components are connected as one, which is beneficial to increasing the structural stability of the sensitization unit.

[0019] 5. The sensitization device for a fully static emulsion explosive disclosed by the present invention is advantageous in that a flow guide tube is arranged around the periphery of the sensitization unit, so that the fluid inside the flow guide tube can be fully sensitized.

[0020] 6. The utility model discloses a sensitization device for a fully static emulsion explosive. By providing a plurality of fluid dispersion sheets, the fluid dispersion component has multiple flow channels, thereby further improving the fluid dispersion efficiency and the sensitization uniformity.

[0021] VII. The present invention discloses a fully static emulsion explosive sensitization device that directs a mixed fluid by providing a feed nozzle and a discharge nozzle. The discharge end diameters of the feed and discharge orifices are smaller than the feed end diameters. As the mixed fluid flows through the feed and discharge orifices, it changes direction, undergoing multiple collisions and mixing. Furthermore, the small diameter of the orifice discharge end increases the fluid pressure, preventing charge backflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0033] like Figures 1 to 6 As shown, the sensitizing device for the fully static emulsion explosive of this embodiment includes a sensitizing tube 1, a feed port 11 is provided at one end of the sensitizing tube 1, and a discharge port 12 is provided at the other end. A fluid dispersion component 2 and two sensitizing units 3 are sequentially provided between the feed port 11 and the discharge port 12 (of course, in other embodiments, other numbers of sensitizing units 3 can also be provided).

[0034] When the sensitization device of the fully static emulsion explosive is used, the latex matrix and the fluids such as the sensitizer and the catalyst enter the sensitization tube 1 from the feed port 11, and collide with each other multiple times and change the flow direction through the fluid dispersion component 2 and the multiple sensitization units 3 arranged in sequence in the sensitization tube 1, so as to achieve the purpose of dispersion, mixing and uniform sensitization.

[0035] Through the above special design, the sensitization device for fully static emulsion explosives of this embodiment has the following advantages:

[0036] First, by integrating the fluid dispersion component 2 and the plurality of sensitizing units 3 in the sensitizing tube 1, the sensitizing device is made compact in structure, avoiding fluid pressure loss caused by an excessively long flow channel.

[0037] Second, by providing a fluid dispersion component 2 and a plurality of sensitizing units 3, the fluid is dispersed and mixed multiple times in the sensitizing tube 1, thereby improving the sensitization uniformity.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, the sensitizing unit 3 includes multiple groups of sensitizing components 31, each of which includes multiple parallel sensitizing plates 32. A gap exists between adjacent sensitizing plates 32 within the sensitizing components 31, and the sensitizing plates 32 of two adjacent groups of sensitizing components 31 are arranged in a cross-shaped arrangement. The multiple sensitizing plates 32 are arranged in a cross-shaped arrangement at intervals, forming a sensitizing unit 3 with multiple sensitizing pores within it. This allows the mixed fluid flowing through the sensitizing unit 3 to be dispersed more times, further improving the uniformity of fluid mixing and enhancing the sensitization effect.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, the sensitizing plates 32 of two adjacent groups of sensitizing components 31 are arranged vertically, which is beneficial to further enhance the sensitization effect of the sensitizing unit.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the sensitizing plates 32 of two adjacent groups of sensitizing components 31 are connected as one, which is beneficial to increasing the structural stability of the sensitizing unit 3 .

[0041] Preferably, the sensitization unit 3 is a 3D-printed integrated sensitization unit, which has good structural stability and is conducive to reducing processing difficulty.

[0042] like Figure 3 As shown, in this embodiment, a flow guide tube 7 is provided in the sensitizing tube 1, and the sensitizing unit 3 is provided in the flow guide tube 7. By providing the flow guide tube 7 around the periphery of the sensitizing unit 3, the fluid inside the flow guide tube 7 is facilitated to be fully sensitized.

[0043] like Figure 6 As shown, in this embodiment, the fluid dispersion component 2 includes two fluid dispersion sheets 21 (of course, in other embodiments, other numbers of fluid dispersion sheets 21 can also be provided), so that the fluid dispersion component 2 has multiple flow channels (the more fluid dispersion sheets 21 there are, the more flow channels there are in the fluid dispersion component 2), further improving the dispersion efficiency and improving the sensitization uniformity.

[0044] like Figure 3As shown, in this embodiment, a feed nozzle 5 is provided at the feed port 11, and the fluid dispersion assembly 2 is provided in the feed nozzle 5. A feed throttling hole 51 is provided at one end of the feed nozzle 5 close to the sensitization unit 3. A discharge nozzle 4 is provided at the discharge port 12, and a discharge throttling hole 41 is provided in the discharge nozzle 4. By providing the feed nozzle 5 and the discharge nozzle 4, the mixed fluid is guided. The discharge end diameters of the feed throttling hole 51 and the discharge throttling hole 41 are smaller than the feed end diameters. When flowing through the feed throttling hole 51 and the discharge throttling hole 41, the mixed fluid changes its flow direction, undergoes multiple collisions and mixing, and the small diameter of the discharge end of the throttling hole increases the fluid pressure, thereby preventing the charge from returning.

[0045] like Figure 3 As shown, in this embodiment, a hole retaining ring 6 is provided inside the feed nozzle 5 for securing the fluid dispersion assembly 2, and a hole retaining ring 6 is provided inside the sensitized tube 1 for securing the feed nozzle 5. The hole retaining ring 6 secures the fluid dispersion assembly 2 and the feed nozzle 5, thereby improving the reliability of the device and facilitating assembly, disassembly, and maintenance.

[0046] like Figures 1 to 3 As shown, in this embodiment, connecting flanges 13 are provided at both ends of the sensitizing tube 1 for connecting the sensitizing device with other process devices. The connecting flanges 13 have a simple structure and are easy to install.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
