Description

Technical Field

[0001] The present invention relates to the technical field of emulsion explosive production, in particular to a mixed emulsion explosive sensitization device and a method thereof. Background Art

[0002] Emulsion explosives are water-in-oil emulsion explosives made by uniformly dispersing droplets of an aqueous solution of an oxidizing salt in an oil-phase continuous medium containing porous materials such as dispersed bubbles or hollow glass microspheres, using an emulsifier. Emulsion explosives feature high density, high detonation velocity, high intensity, good water resistance, a small critical diameter, and excellent initiation sensitivity. At small diameters, they exhibit detonator sensitivity. Density can generally be controlled to 1.05-1.25 g / cm³, and detonation velocity ranges from 3500-5000 m / s. They typically do not use explosives as sensitizers, resulting in safe production and minimal pollution. Emulsion explosives are typically emulsified using chemical or physical sensitization.

[0003] Patent document CN116854547A discloses a low-temperature sensitization device for packaged emulsion explosives, including a storage mechanism and a filling mechanism. The filling mechanism includes a lifting component arranged at the upper end of the storage mechanism and a stirring component arranged on the lifting component and used to stir and compact the sensitizing material, mixing the microporous particles and the powdered sensitizing material together. Subsequently, driven by the lifting component and the stirring component, the stirring component will evenly mix the microporous particles and the powdered sensitizing material while compacting the microporous particles and the powdered sensitizing material, thereby pressing the sensitizing material into the interior of the microporous particles. After multiple stirring and compacting operations, the microporous particles can be filled with the sensitizing material.

[0004] However, in actual use, sensitizing emulsion explosives with glass microspheres is costly and the glass microspheres cannot be quickly and evenly distributed in the emulsion matrix. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology. By providing an extruder, a placement mechanism and a twisting mechanism, the emulsified matrix is ​​output in a specific strip shape, which facilitates the uniform placement of glass microbeads into the emulsified matrix. In addition, a large number of bubbles are retained during the re-fusion process to complement the glass microbeads, thereby solving the technical problems of difficult diffusion of glass microbeads and high cost.

[0006] In response to the above technical problems, the technical solutions adopted are as follows:

[0010] A placement mechanism, which is disposed in the middle of the pipe group and is used to cooperate with the pipe group to achieve the placement of the glass beads;

[0011] The twisting mechanism is used to twist the strip-shaped emulsified matrix back into a whole and form an air cavity therein.

[0012] Preferably, the extruder is used to extrude the input emulsified matrix into a plurality of strip-shaped emulsified matrices, wherein the cross-sections of the other strip-shaped emulsified matrices are all ring-shaped with gaps except for the central strip-shaped emulsified matrix having a circular cross-section, and the outer strip-shaped emulsified matrices are arranged in a ring shape with the gaps all facing the central strip-shaped emulsified matrix.

[0013] Preferably, the pipeline group includes multiple pipelines for moving the strip emulsification mechanism, and the rear half of the pipeline is inclined toward the central strip emulsification matrix. At the same time, the lower part of each pipeline is provided with a water guide groove and multiple moving rollers for assisting the movement of the emulsification matrix. The side of the inclined section of the pipeline that contacts the notch of the strip emulsification matrix is ​​provided with a through groove.

[0015] Preferably, the placement mechanism includes multiple groups of nozzles arranged between the pipes and with the spraying direction facing the through grooves on each pipe, a conduit arranged at the end of the nozzle and facing the emulsified matrix gap in the pipe, a feeding pipe connected to the conduit and feeding the glass microbeads into the conduit one by one through the electric cylinder, and a water receiving tray arranged under the pipe.

[0016] Preferably, the twisting mechanism includes a reshaping component arranged behind the pipeline group for reshaping the shape of the strip emulsion matrix, a twisting component arranged behind the reshaping component and for twisting the strip emulsion matrix into one piece, and a forming component arranged in the middle of the twisting component and for setting air cavities between each strip emulsion matrix.

[0017] Preferably, the reshaping assembly includes a plurality of reshaping tubes arranged at the output end of the pipeline, a plurality of rotating tubes rotatably connected in the reshaping tubes, and a transverse plate arranged in each rotating tube;

[0018] The invention also comprises a shaping tube arranged behind the shaping tube, four sets of telescopic cylinders arranged around the shaping tube, and a push plate fixed on the telescopic rods of the telescopic cylinders and used for shaping the emulsified matrix into a rectangle.

[0019] Preferably, the twisted assembly includes a first orifice plate arranged behind the reshaping assembly, a second orifice plate arranged behind the first orifice plate, and a twisted ring arranged behind the second orifice plate. The first orifice plate and the second orifice plate are both provided with through holes for accommodating the passage of the strip emulsified matrix, and the second orifice plate has a smaller area than the first orifice plate and a higher density of through holes. The twisted ring is rotatably connected to the base and driven by a motor.

[0020] Preferably, the forming assembly includes floating rollers arranged at both ends of the second orifice plate through hole, an infrared detector arranged in the second orifice plate through hole, an electric cylinder controlled by the infrared detector, and a protrusion fixed on the telescopic rod of the electric cylinder.

As the emulsified matrix moves, the nozzle intermittently sprays water toward the emulsified matrix. The sprayed water flow carries the glass microbeads in the conduit into the emulsified matrix, and the extruder seals the gap of the emulsified matrix.

[0023] Step 2, the reshaping step, the emulsified matrix continues to move, and is reshaped into a circular cross section through the reshaping tube, and then processed again to make the cross section rectangular, and a bubble groove is dug out on the surface;

[0046] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figure 1 As shown, a mixed emulsion explosive sensitization device comprises:

[0049] Extruder 0, which is arranged at the front end of the device and is used to extrude the emulsified matrix into strips for output;

[0050] Pipeline group 1, which is arranged behind the extruder 0 and is used to assist the movement of the strip-shaped emulsified matrix;

[0051] A placement mechanism 2, which is disposed in the middle of the pipeline group 1 and is used to cooperate with the pipeline group 1 to achieve the placement of glass beads;

[0052] The twisting mechanism 3 is used to twist the strip-shaped emulsified matrix back into a whole and form an air cavity therein.

[0053] In this embodiment, the placement mechanism 2 and the twisting mechanism 3 are provided to achieve uniform release of the glass microbeads, and by reshaping the emulsified matrix, bubbles are uniformly added to the emulsified matrix. The uniform arrangement of the glass microbeads and bubbles improves the sensitization effect of the emulsified matrix.

[0054] In detail, the emulsified matrix is ​​extruded into a strip by the extruder 0 and input into the pipeline group 1 for movement. Glass microbeads are evenly added to the strip of emulsified matrix during its movement by the placement mechanism 2. After the addition of the glass microbeads, the strip of emulsified matrix is ​​reshaped. The strip of emulsified matrix is ​​then twisted, fused into a whole again and output. While the strip of emulsified matrix is ​​twisted, its surface is treated so that bubbles are formed when the strips of emulsified matrix contact each other and remain in the middle of the emulsified matrix.

[0055] It should be noted that by adding glass microbeads to the strip emulsion matrix and then fusing the strip emulsion matrix into a whole, while the strip emulsion matrix is ​​fused, the gaps between each strip emulsion matrix are utilized to allow bubbles to remain in the middle of the emulsion matrix, and the positions of the bubbles and the glass microbeads are staggered and complement each other, thereby improving the sensitization effect while reducing costs.

[0056] It is worth mentioning that the placement mechanism 2 and the twisting mechanism 3 make the glass beads distributed more evenly and quickly.

[0057] Further, if Figure 2 As shown, the extruder 0 is used to extrude the input emulsified matrix into multiple strip-shaped emulsified matrices. Except for the central strip-shaped emulsified matrix having a circular cross-section, the cross-sections of the remaining strip-shaped emulsified matrices are all ring-shaped with gaps. At the same time, the outer strip-shaped emulsified matrices are arranged in a ring shape with the gaps all facing the central strip-shaped emulsified matrix.

[0058] In this embodiment, the extruder 0 is provided so that the emulsified matrix can be output as a strip-shaped emulsified matrix with a specific structure, thereby facilitating the development and execution of subsequent steps.

[0059] In detail, the emulsified matrix is ​​input into the extruder 0 for extrusion, and the extruder 0 extrude the emulsified matrix into a strip. The cross-section of the strip emulsified matrix is ​​a ring with a gap. This shape is conducive to the subsequent addition of glass microbeads to the middle of the strip emulsified matrix, and the strip emulsified matrix is ​​arranged along the ring, which is conducive to the subsequent twisting of the emulsified matrix.

[0060] It should be noted that the hollow portion in the middle of the strip-shaped emulsified matrix should be just large enough to accommodate the glass microbeads.

[0061] It is worth mentioning that the strip-shaped emulsified matrix in the middle is circular, which is conducive to subsequently wrapping the outer emulsified matrix around the central emulsified matrix to prevent mutual fusion.

[0062] Further, if Figure 3 As shown, the pipeline group 1 includes multiple pipelines 11 for moving the strip emulsification mechanism, and the rear half of the pipeline 11 is inclined toward the central strip emulsification matrix. At the same time, the lower part of each pipeline 11 is provided with a water guide groove and multiple moving rollers 12 for assisting the movement of the emulsification matrix. The side of the inclined section of the pipeline 11 that contacts the notch of the strip emulsification matrix is ​​provided with a through groove 13.

[0063] In this embodiment, the pipe 11 is provided to enable the strip-shaped emulsified matrix to move along a preset track, thereby preventing the strip-shaped emulsified matrix from being broken due to gravity while moving.

[0064] In detail, the emulsified matrix is ​​extruded by the extruder 0 and input into the pipe 11. The moving roller 12 in the pipe 11 assists the emulsified matrix to move in the pipe 11 and continuously outputs it forward, so that the emulsified matrix moves continuously and stably to avoid the emulsified matrix from breaking.

[0065] It should be noted that a water guide trough is provided below each pipe 11 for guiding out excess water stains during the subsequent placement process.

[0066] It is worth mentioning that by providing the through groove 13, the emulsified matrix is ​​exposed, thereby preventing the glass microbeads from entering the emulsified matrix.

[0067] Further, if Figure 4 、 Figure 5 As shown, the pipeline group 1 also includes an extrusion member 14 arranged in each pipeline 11. The extrusion member 14 is arranged behind the through groove 13 in each pipeline 11, and includes two groups of pressing rollers 141 respectively located on both sides of the emulsified matrix gap, a rotating frame 142 for fixing the pressing rollers 141 and rotatably connected to the pipeline 11, and a paddle 143 arranged in the middle of the rotating frame 142 and rotatably connected to the outside of the pipeline 11.

[0068] In this embodiment, the pressing roller 141 is provided to fix the glass microbeads and squeeze out excess air in the emulsified matrix so that the emulsified matrix wraps the glass microbeads.

[0069] In detail, the pressing rollers 141 are arranged on both sides of the emulsified matrix to compact the gaps in the emulsified matrix and the hollow part in the middle. When the glass beads are fed into the emulsified matrix, the paddle 143 moves the rotating frame 142 to rotate the pressing rollers 141. The pressing rollers 141 separate to both sides, jump over the position where the glass beads are locked, and then approach again to continue compacting.

[0070] It should be noted that the rotating shaft of the rotating frame 142 is set at a lower middle position, so that after the rotating frame 142 rotates, the lower end of the pressing roller 141 can still compact the gap below the glass beads.

[0071] Further, if Figure 6 、 Figure 7 、 Figure 12 As shown, the placement mechanism 2 includes a plurality of nozzles 21 arranged between the pipes 11 and with the spraying direction facing the through grooves 13 on each pipe 11, a conduit 22 arranged at the end of the nozzle 21 and facing the emulsified matrix gap in the pipe 11, a feeding pipe 23 connected to the conduit 22 and feeding the glass microbeads into the conduit 22 one by one through the electric cylinder, and a water receiving tray 24 arranged below the pipe.

[0072] In this embodiment, the nozzle 21 and the conduit 22 are provided to move the glass microbeads so that the glass microbeads can be released into the emulsified matrix in a timely manner.

[0073] In detail, a large number of glass beads are stored in the feeding tube 23, and the glass beads are released one by one into the conduit 22 through the electric cylinder. The nozzle 21 sprays water intermittently, and uses the water flow to send the glass beads in the conduit 22 into the emulsified matrix to achieve the placement of the glass beads.

[0074] It should be noted that the glass beads can be delivered by precisely controlling the nozzle 21. On the one hand, the timing of delivering the glass beads can be precisely controlled so that all the glass beads are kept in the same plane. On the other hand, the structure is simple, which facilitates the delivery of the glass beads.

[0075] It is worth mentioning that, while the water flow brings out the glass beads, it also impacts the paddle 143 , causing the paddle 143 to rotate, thereby controlling the movement of the pressure roller 141 .

[0076] Further, if Figure 8 As shown, the twisting mechanism 3 includes a reshaping component 31 disposed behind the pipeline group 1 for reshaping the shape of the strip emulsified matrix, a twisting component 32 disposed behind the reshaping component 31 and for twisting the strip emulsified matrix into one piece, and a forming component 33 disposed in the middle of the twisting component 32 and for setting air cavities between each strip emulsified matrix.

[0077] In this embodiment, the shape of the emulsion matrix is ​​reshaped by providing a reshaping component 31, a twisting component 32, and a molding component 33. After the reshaping is completed, twisting is performed. At the same time, reserved air holes are provided on each emulsion matrix so that bubbles interlaced with the glass beads are formed after the emulsion matrix is ​​fused.

[0078] Specifically, the reshaping component 31 is used to reshape the strip-shaped emulsified matrix, making the shape of the strip-shaped emulsified matrix more convenient for subsequent fusion. Then, the strip-shaped emulsified matrix is ​​input into the twisting component 32 to make the strip-shaped emulsified matrix approach each other and rotate, adhere to each other, twist together, and fuse to form a complete cylindrical emulsified matrix for output. During the twisting process, the shaping component 33 leaves grooves on the surface of each strip-shaped emulsified matrix, so that bubbles are formed inside the emulsified matrix after the emulsified matrix adheres.

[0079] Further, if Figure 9 、 Figure 10 、 Figure 11 As shown, the reshaping assembly 31 includes multiple groups of reshaping tubes 311 disposed at the output end of the pipeline 11, multiple groups of rotating tubes 312 rotatably connected to the reshaping tubes 311, and horizontal plates 313 disposed in each rotating tube 312. It also includes a shaping tube 314 disposed behind the reshaping tube 311, four groups of telescopic cylinders disposed around the shaping tube 314, and a push plate 315 fixed to the telescopic rods of the telescopic cylinders and used to reshape the emulsified matrix into a rectangular shape.

[0080] In this embodiment, the reshaping tube 311 and the forming tube 314 are provided to reshape the strip-shaped emulsified matrix. The emulsified matrix is ​​reshaped into a circle and then extruded into a rectangle.

[0081] Specifically, the emulsified matrix is ​​fed into the reshaping tube 311 , and the rotating tube 312 in the reshaping tube 311 rotates, using the horizontal plate 313 to gradually turn the emulsified matrix into a circle. The emulsified matrix is ​​then fed into the shaping tube 314 , and the telescopic rod of the telescopic cylinder pushes the push plate 315 , turning the emulsified matrix into a rectangle.

[0082] It should be noted that the rotation of the horizontal plate 313 makes the emulsified matrix round, thereby preventing the glass microbeads therein from moving and keeping the glass microbeads at the center of the emulsified matrix at all times.

[0083] It is worth mentioning that the emulsified matrix is ​​finally output as a rectangle, which is beneficial to the subsequent twisting process, so that each emulsified matrix fits together during the twisting process and reduces gaps.

[0084] Further, if Figure 12 、 Figure 13 As shown, the twisting assembly 32 includes a first orifice plate 321 arranged behind the reshaping assembly 31, a second orifice plate 322 arranged behind the first orifice plate 321, and a twisting ring 323 arranged behind the second orifice plate 322. The first orifice plate 321 and the second orifice plate 322 are both provided with through holes for accommodating the passage of the strip emulsified matrix, and the second orifice plate 322 has a smaller area than the first orifice plate 321 and a higher density of through holes. The twisting ring 323 is rotatably connected to the base and driven by a motor.

[0085] In this embodiment, the first orifice plate 321 , the second orifice plate 322 and the twisting ring 323 are provided to achieve twisting output of the strip-shaped emulsified matrix.

[0086] In detail, the through hole in the first orifice plate 321 is adapted to the outlet of the pipe 11, allowing the emulsified matrix to enter the twisted assembly 32, and then pass through the first orifice plate 321 to the second orifice plate 322. Between the first orifice plate 321 and the second orifice plate 322, the strips of emulsified matrix are close to each other and then input into the interior of the twisted ring 323. The rotation of the twisted ring 323 drives the outer emulsified matrix to rotate, and the strips of emulsified matrix adhere to each other and finally merge into a complete whole. The glass beads are evenly distributed in the final emulsified matrix.

[0087] It should be noted that both the reshaping tube 311 and the forming tube 314 can be disposed on the first orifice plate 321 .

[0088] It is worth mentioning that the through holes of the second orifice plate 322 are configured to be rectangular.

[0089] Further, if Figure 14 As shown, the forming assembly 33 includes floating rollers 331 arranged at both ends of the through hole of the second orifice plate 322, an infrared detector 332 arranged in the through hole of the second orifice plate 322, an electric cylinder controlled by the infrared detector 332, and a protrusion 333 fixed on the telescopic rod of the electric cylinder.

[0090] In this embodiment, by providing an infrared detector and the protrusion 333 , grooves are provided at specific positions of the strip-shaped emulsified matrix, so that the bubbles retained in the final emulsified matrix complement the glass beads.

[0091] In detail, during the movement of the emulsified matrix, the infrared detector continuously detects the emulsified matrix. When the infrared detector detects the glass beads in the emulsified matrix, it drives the electric cylinder to press out a groove at a certain distance from the glass beads through the protrusion 333, so that the bubble and the glass beads maintain a fixed position.

[0092] It should be noted that the groove is provided inside the emulsified matrix, and therefore, no protrusion 333 is provided on the outer surface of the outermost emulsified matrix.

[0093] It is worth mentioning that, as needed, multiple groups of bumps 333 can be set in the through hole to change the density and position of the final bubbles, so that the bubbles and the glass positions can achieve a better complementary effect.

For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0096] The mixed emulsion explosive sensitization method is applied to a mixed emulsion explosive sensitization device, comprising the following steps:

[0097] Step 1: The emulsified matrix is ​​fed into the extruder 0 to output a plurality of strips of emulsified matrix. The strips of emulsified matrix enter the pipe 11 and move. As the emulsified matrix moves, the nozzle 21 intermittently sprays water toward the emulsified matrix. The sprayed water carries the glass microbeads in the conduit 22 into the emulsified matrix, and the extruder 14 seals the gap in the emulsified matrix.

[0098] Step 2, the reshaping step, the emulsified matrix continues to move, and is first reshaped into a circular cross section through the reshaping tube 311, and then re-processed to make the cross section rectangular, and bubble grooves are dug out on the surface;

[0099] Step three is the twisting step, in which the processed emulsified matrix passes through the first orifice plate 321, the second orifice plate 322 and the twisting ring 323 in sequence, so that the emulsified matrix is ​​twisted together to achieve fusion and output of multiple emulsified matrices.
