Description

Technical Field

[0001] This utility model relates to the technical field of emulsion explosive production equipment, specifically a device for precisely controlling the sensitization rate of emulsion explosives. Background Technology

[0002] Emulsion explosives, as the mainstay of industrial explosives, are widely used in large-scale blasting operations such as mining, tunnel excavation, and water conservancy projects due to their excellent explosive performance, good water resistance, and high safety. Sensitization, as a key step in the production process of emulsion explosives, plays a crucial role. The sensitization process involves introducing microbubbles or sensitizers into the emulsion matrix of the explosive to create detonation hotspots, ensuring stable and efficient detonation. The quality of the sensitization effect directly affects the key performance indicators of emulsion explosives. Currently, the control of sensitization speed in emulsion explosive production needs improvement.

[0003] To address the aforementioned deficiencies, existing technology (Chinese patent announcement number CN206289187U, announcement date 2017-06-30) provides a device for controlling the sensitization speed of emulsion explosives. The emulsion explosive matrix on a steel strip cooler, after being uniformly sprayed with sensitizer, enters the feed hopper. It is rapidly mixed under the pre-stirring of an "X"-shaped feed agitator. A hydraulic cylinder in the feed opening control mechanism is controlled to open and close multi-stage telescopic plates as needed to adjust the feed speed. After sufficient pre-stirring, the material enters the sensitization tank where a spiral stirring mechanism thoroughly sensitizes and stirs before discharge. A speed-regulating motor can adjust the stirring rate of the spiral stirring mechanism as needed. The pre-stirring and spiral stirring work together to control the sensitization speed in a timely manner, thereby improving product quality.

[0004] The above-mentioned solution achieves the fusion of sensitizer and latex matrix through a simple stirrer during use. However, due to dead zones in the stirring, the sensitizer may accumulate locally, leading to "locally too fast sensitization" or "locally insufficient sensitization". The uniformity of stirring and mixing directly affects the reaction results. Furthermore, adjusting the speed can only roughly affect the mixing efficiency and cannot be directly correlated with the sensitization reaction rate. The fixed position of the sensitizer spraying component makes it difficult for the sensitizer to quickly form a "microscopic encapsulation" state with the latex matrix during the treatment process, resulting in fluctuations in the sensitization rate due to uneven distribution. Utility Model Content

[0005] The purpose of this invention is to provide a device for precisely controlling the sensitization rate of emulsion explosives, in order to solve the problems mentioned in the background art regarding existing devices for controlling the sensitization rate of emulsion explosives. In use, the sensitizer and the latex matrix are fused through a simple stirrer, but the sensitizer is prone to local aggregation due to dead zones in the stirring, leading to "local over-sensitization" or "local under-sensitization". The uniformity of stirring and mixing directly affects the reaction results, and adjusting the speed roughly affects the mixing efficiency, but cannot be directly correlated with the sensitization reaction rate. The position of the sensitizer spraying component is fixed, which makes it difficult for the sensitizer to quickly form a "microscopic encapsulation" state with the latex matrix during the processing, resulting in the problem of fluctuation in the sensitization rate due to uneven distribution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for precisely controlling the sensitization speed of emulsion explosives, comprising a sensitization chamber, the top of which is connected to a sensitization tank, a mixing channel being provided inside the sensitization chamber, a first motor being installed on the left side inside the sensitization chamber, the output end of which is connected to a spiral stirrer, the spiral stirrer being rotatably connected in the mixing channel, a second motor being installed on the top of the sensitization tank, the output end of which is connected to a shaft via a sprocket mechanism, the shaft being located inside the sensitization tank, a circular plate being fixed to the outer side of the top of the shaft, and mixing rods being provided at equal angles at the bottom of the circular plate.

[0007] The top of the circular plate is provided with a uniform modulation structure, and the uniform modulation mechanism improves the fusion efficiency of the sensitizer and the latex matrix by driving the mixing rod to move in multiple directions.

[0008] The bottom of the circular plate is provided with nozzles at equal angles, and a full-coverage mechanism is provided between the top of the nozzles and the top of the sensitization tank. The full-coverage mechanism accelerates the encapsulation of the sensitizer and the latex matrix by driving the nozzles to move evenly and comprehensively.

[0009] Furthermore, the uniform modulation mechanism includes a gear rotatably connected to the top of the circular plate at an equal angle. The outer side of the gear meshes with a gear ring, which is fixed to the inner top of the sensitization chamber. Temperature sensors are symmetrically installed on the inner top of the sensitization chamber.

[0010] This setup allows the rotating disc to engage the gear with the gear ring, causing the gear to rotate on its own axis. Furthermore, the temperature sensor can monitor the temperature inside the tank in real time, feeding the data back to the control system.

[0011] Furthermore, a rectangular sliding column is slidably connected through the middle of the gear, and the bottom of the sliding column slides through the bottom of the circular plate. The part where the bottom of the sliding column passes through the circular plate is set as a circular through-hole. A mixing rod is fixed to the bottom of the sliding column. The surface of the mixing rod is covered with a conductive silicone layer and grounded through a shaft.

[0012] This configuration allows the gear to rotate, causing the slide column to rotate synchronously, which in turn drives the mixing rod to rotate synchronously, thus improving mixing efficiency.

[0013] Furthermore, the sliding column drives the mixing rod to form a structure that rotates synchronously with the revolution through gears and gear rings, thereby improving the fusion efficiency of the sensitizer and the latex matrix. The mixing rod is configured as a comb-shaped structure.

[0014] This setup allows the comb-like arrangement of the mixing rod to better agitate and blend the sensitizer with the latex matrix.

[0015] Furthermore, a return spring is installed at the bottom of the sliding column, and the top of the return spring abuts against the bottom of the circular plate through a washer. The top of the sliding column intermittently abuts against the protrusions of the hemispherical structure. The height of the protrusions is 1 / 3 of the length of the sliding column. The protrusions are installed at equal angles on the inner side of the top of the sensitization tank. The sliding column drives the mixing rod to move up and down reciprocally through the return spring and the protrusions, further improving the fusion efficiency of the sensitizer and the latex matrix.

[0016] This design allows the slide bar to rotate while simultaneously increasing the vertical sliding of the return spring and the protrusion, thereby enhancing the multidirectional movement of the mixing rod and further increasing the fusion rate of the sensitizer and the latex matrix.

[0017] Furthermore, the full-coverage mechanism includes a limiting groove equally angled on a circular plate. The limiting groove is a linear structure, and a vertical rod is slidably connected in the limiting groove. The top of the vertical rod is slidably connected in a guide groove, which is a flower-shaped structure. The guide groove is located on the inner top of the sensitization tank. A nozzle is fixed at the bottom of the vertical rod, and a piezoelectric ceramic sheet is embedded in the nozzle to receive pulse signals and prevent crystallization blockage.

[0018] This design allows the vertical rod to slide synchronously in the limiting groove and guide groove as the circular plate rotates with the shaft, thereby driving the lower mixing rod to open and close.

[0019] Furthermore, the vertical rod drives the nozzle to form an opening and closing sliding structure through the limiting groove and the guide groove. The circular plate drives the nozzle to rotate circumferentially through the vertical rod to fully cover the structure. The nozzle is connected to the electromagnetic pump through the connecting pipe. The electromagnetic pump is connected to the liquid storage tank through the connecting pipe. Both the electromagnetic pump and the liquid storage tank are installed on the top rear side of the sensitization tank.

[0020] With this setup, the opening, closing, sliding, and circumferential rotation of the vertical rod will simultaneously drive the bottom nozzle to move synchronously, ensuring that the sprayed sensitizer is evenly coated on the outside of the emulsion matrix.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This device for precisely controlling the sensitization rate of emulsion explosives, in its operation, focuses on pretreatment, dynamic spraying, multi-directional stirring, and temperature control. It ensures uniform initial distribution of the sensitizer through comprehensive coverage spraying without dead angles, achieves full fusion at the microscopic level through the multi-directional movement of the uniform modulation mechanism, and finally adjusts parameters dynamically through temperature feedback to reduce sensitization rate deviation, thus solving the pain points of local reaction imbalance and low control precision of traditional devices.

[0023] 1. Furthermore, the temperature sensor monitors the temperature inside the tank in real time and feeds the data back to the control system. If the temperature is too high, the system can reduce the spraying rate of the electromagnetic pump or reduce the stirring intensity of the mixing rod by reducing the rotation speed of the circular plate to slow down the reaction. If the temperature is too low, the spraying rate and stirring intensity are increased, and mechanical friction is used to supplement heat and accelerate mixing to ensure that the sensitization rate is stable within the preset range.

[0024] 2. Furthermore, the second motor drives the shaft to rotate the circular plate, triggering the multi-dimensional stirring of the uniform modulation mechanism. When the gear at the top of the circular plate revolves with the circular plate, it meshes with the fixed gear ring, causing the gear to rotate. The rectangular sliding column in the middle of the gear rotates with the gear, thereby driving the mixing rod at the bottom to rotate synchronously. At the same time, the sliding column revolves with the circular plate, causing the mixing rod to form a composite motion trajectory of "revolution + rotation". The comb-shaped mixing rod cuts and disperses the material during the movement, increasing the contact area with the sensitizer and improving the mixing uniformity.

[0025] 3. Furthermore, when the top of the sliding column intermittently contacts the hemispherical protrusion inside the sensitization tank, the sliding column is pressed down and the return spring is compressed; after disengaging from the protrusion, the return spring rebounds and pushes the sliding column upward, causing the mixing rod to reciprocate up and down. The stroke is determined by the height of the protrusion. This movement expands the mixing from a plane to a three-dimensional space, further tearing apart the matrix agglomerates and ensuring that the sensitizer uniformly coats the matrix particles, providing a microscopic basis for precise control of the sensitization speed.

[0026] 4. Furthermore, while the circular plate drives the mixing rod to stir, it also drives the bottom nozzle to move, enabling the full-coverage mechanism to dynamically spray the sensitizer, achieving a synergistic effect of "stirring and spraying simultaneously." As the circular plate rotates, the bottom vertical rod slides along the straight limiting groove on the plate, while its top is embedded in the flower-shaped guide groove inside the sensitization tank. Due to the curved trajectory constraint of the guide groove, the vertical rod slides inside and outside the limiting groove while revolving with the circular plate, causing the nozzle to form a "circumferential rotation + radial opening and closing" effect. The combined motion of the nozzle and the mixing rod involves the nozzle drawing sensitizer from the storage tank via an electromagnetic pump. This dynamic motion achieves comprehensive coverage of the material inside the sensitization tank, accelerating the "microscopic encapsulation" of the sensitizer and the matrix. The spraying area of ​​the nozzle partially overlaps with the stirring area of ​​the mixing rod. As soon as the sensitizer is sprayed, it is cut and dispersed by the nearby mixing rod, preventing droplet aggregation. At the same time, the up-and-down movement of the mixing rod flips the lower layer of material to the upper layer, allowing it to come into contact with the newly sprayed sensitizer from the nozzle, forming a cyclical reinforcement effect of "spraying-stirring-re-spraying".

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1: Please refer to Figure 1 - Figure 2 and Figure 8 The present invention provides the following technical solution: a device for precisely controlling the sensitization speed of emulsion explosive, comprising a sensitization chamber 1, the top of which is connected to a sensitization tank 2, a mixing channel being provided inside the sensitization chamber 1, a first motor 3 being installed on the left side inside the sensitization chamber 1, a spiral stirrer 4 being connected to the output end of the first motor 3, the spiral stirrer 4 being rotatably connected in the mixing channel, a second motor 5 being installed on the top of the sensitization tank 2, a shaft 6 being connected to the output end of the second motor 5, the shaft 6 being located inside the sensitization tank 2, a circular plate 7 being fixed on the outer side of the top of the shaft 6, mixing rods 11 being provided at equal angles on the bottom of the circular plate 7, and temperature sensors 20 being symmetrically installed on the top inner side of the sensitization chamber 1.

[0038] In use, the emulsion matrix to be treated is added through the side inlet of the sensitization tank 2. The second motor 5 drives the shaft 6 to rotate via a sprocket mechanism. The shaft 6 drives the circular plate 7 to move, thereby activating the mixing rod 11 to fully integrate the sensitizer and emulsion matrix, breaking up matrix agglomerates, reducing matrix viscosity, making subsequent sensitizer spraying easier to penetrate, and reducing the risk of local aggregation. The treated material enters the mixing channel in the sensitization chamber 1. The first motor 3 drives the spiral stirrer 4 to rotate, pushing the material along the channel while stirring. The temperature sensor 20 at the top of the sensitization tank 2 monitors the temperature inside the tank in real time, and the data is fed back to the control system. If the temperature is too high (accelerating the sensitization reaction), the system can... Reduce the spraying rate of electromagnetic pump 18, or reduce the stirring intensity of mixing rod 11 by reducing the rotation speed of circular plate 7 (reducing frictional heat generation) to slow down the reaction. If the temperature is too low (slowing down the sensitization reaction), increase the spraying rate and stirring intensity. When the temperature exceeds the threshold of 30℃, the control system adjusts the flow rate according to Q = Q0[1-0.05(T-30)] to supplement heat and accelerate mixing through mechanical friction, ensuring that the sensitization speed is stable within the preset range. Temperature sensor reading > set threshold: second motor speed = current speed × (1-0.02 × temperature difference), electromagnetic pump flow rate = maximum flow rate × (1-0.03 × temperature difference). The processed emulsion explosive is output and collected from the right end of sensitization chamber 1.

[0039] Example 2:

[0040] Based on Example 1, a mechanism for the rapid and uniform fusion of the sensitizer and the latex matrix is ​​also disclosed. Please refer to [link / reference]. Figure 2 - Figure 5 As shown, its specific structure is as follows: The top of the circular plate 7 is provided with a uniform modulation structure, and the uniform modulation mechanism improves the fusion efficiency of the sensitizer and the latex matrix by driving the mixing rod 11 to move in multiple directions. The uniform modulation mechanism includes a gear 8 that is rotatably connected to the top of the circular plate 7 at equal angles. The outer side of the gear 8 meshes with the toothed ring 9. The toothed ring 9 is fixed to the top of the inner side of the sensitization chamber 1. A rectangular sliding column 10 is slidably connected through the middle of the gear 8. The bottom of the sliding column 10 slides through the bottom of the circular plate 7. The part where the bottom of the sliding column 10 passes through the circular plate 7 is set as a circular opening. The mixing rod 11 is fixed to the bottom of the sliding column 10. The sliding column 10 drives the mixing rod 11 to form a structure that rotates synchronously around the sun and rotates on its own axis through the gear 8 and the toothed ring 9, thereby improving the fusion efficiency of the sensitizer and the latex matrix. The mixing rod 11 is set as a comb-shaped structure.

[0041] During use, when the material enters the main area of ​​the sensitization tank 2, the second motor 5 drives the shaft 6 to rotate the circular plate 7, triggering the multi-dimensional stirring of the uniform modulation mechanism. When the gear 8 at the top of the circular plate 7 revolves with the circular plate 7, it meshes with the fixed gear ring 9, causing the gear 8 to rotate. The rectangular sliding column 10 in the middle of the gear 8 rotates with the gear 8, thereby driving the mixing rod 11 at the bottom to rotate synchronously. The module of the gear 8 and the gear ring 9 are both 2mm, and the gear ratio is 1:4. At the same time, the sliding column 10 revolves with the circular plate 7, so that the mixing rod 11 forms a composite motion trajectory of "revolution + rotation". The comb-shaped mixing rod 11 cuts and disperses the material during the movement, increasing the contact area with the sensitizer, avoiding dead corners such as the edge of the tank wall in traditional single stirring, and improving the mixing uniformity. At the same time, the surface of the mixing rod 11 is covered with a conductive rubber layer and grounded through the shaft 6 to avoid the problem of static sparks that may be generated by the friction between the mixing rod 11 and the material during the stirring process.

[0042] like Figure 4 - Figure 5 As shown, a return spring 12 is installed at the bottom of the sliding column 10. The top of the return spring 12 abuts against the bottom of the circular plate 7 through a washer. The top of the sliding column 10 intermittently abuts against the protrusion 13 of the hemispherical part. The protrusion 13 is installed at an equal angle on the inner side of the top of the sensitization tank 2. The sliding column 10 drives the mixing rod 11 to move up and down reciprocally through the return spring 12 and the protrusion 13, which further improves the fusion efficiency of the sensitizer and the latex matrix. The elastic coefficient of the return spring 12 is 80 N / m and the pre-compression amount is 10 mm.

[0043] During use, when the top of the sliding column 10 intermittently contacts the hemispherical protrusion 13 inside the sensitization tank 2, the sliding column 10 is pressed down and the return spring 12 is compressed. After disengaging from the protrusion 13, the return spring 12 rebounds and pushes the sliding column 10 upward, causing the mixing rod 11 to move up and down. The stroke is determined by the height of the protrusion 13. This movement expands the mixing from a plane to a three-dimensional space, further tearing the matrix clumps and ensuring that the sensitizer uniformly coats the matrix particles, providing a microscopic basis for precise control of the sensitization speed.

[0044] Example 3:

[0045] Based on Example 2, a mechanism for rapidly and stably forming microscopic encapsulations between the sensitizer and the latex matrix, thereby stabilizing the sensitization rate and reducing sensitization fluctuations, is also disclosed. Please refer to [link / reference needed]. Figure 3 , Figure 6 - Figure 7 As shown, its specific structure is as follows: a nozzle 16 is set at an equal angle at the bottom of the circular plate 7, and a full-coverage mechanism is set between the top of the nozzle 16 and the top of the sensitization tank 2. The full-coverage mechanism accelerates the encapsulation of the sensitizer and the latex matrix by driving the nozzle 16 to move evenly and comprehensively. Since the sensitizer is prone to crystallization and may block the narrow nozzle, the nozzle 16 has a built-in ultrasonic transducer for safety. Specifically, the nozzle 16 is embedded with a piezoelectric ceramic sheet to receive a 20kHz pulse signal to prevent crystallization blockage.

[0046] During use, while the circular plate 7 drives the mixing rod 11 to stir, the circular plate 7 also drives the bottom nozzle 16 to move, so that the full coverage mechanism drives the nozzle 16 to dynamically spray the sensitizer, achieving the synergistic effect of "stirring and spraying at the same time".

[0047] like Figure 6 - Figure 7 As shown, the full coverage mechanism includes a limiting groove 14 that is opened at equal angles on the circular plate 7. The limiting groove 14 is a straight structure. A vertical rod 15 is slidably connected in the limiting groove 14. The top of the vertical rod 15 is slidably connected in the guide groove 17. The guide groove 17 is a flower-shaped structure. The guide groove 17 is opened on the inner top of the sensitization tank 2. A nozzle 16 is fixed at the bottom of the vertical rod 15.

[0048] During use, when the circular plate 7 rotates, the bottom vertical rod 15 slides along the straight limiting groove 14 on the circular plate 7. At the same time, the top of the vertical rod 15 is embedded in the flower-shaped guide groove 17 inside the sensitization tank 2. Due to the constraint of the curved trajectory of the guide groove 17, the vertical rod 15 slides inside and outside along the limiting groove 14 while revolving with the circular plate 7, driving the nozzle 16 to form a compound motion of "circumferential rotation + radial opening and closing".

[0049] like Figure 5 and Figure 7As shown, the vertical rod 15 drives the nozzle 16 to form an opening and closing sliding structure through the limiting groove 14 and the guide groove 17. The circular plate 7 drives the nozzle 16 to rotate circumferentially through the vertical rod 15 to fully cover the structure. The nozzle 16 is connected to the electromagnetic pump 18 through the connecting pipe. The electromagnetic pump 18 is connected to the liquid storage tank 19 through the connecting pipe. The electromagnetic pump 18 and the liquid storage tank 19 are both installed on the top rear side of the sensitization tank 2.

[0050] During use, the nozzle 16 draws sensitizer from the storage tank 19 via the electromagnetic pump 18, achieving full coverage of the material in the sensitization tank 2 in dynamic motion, accelerating the "microscopic encapsulation" of the sensitizer and the matrix. The spraying area of ​​the nozzle 16 partially overlaps with the stirring area of ​​the mixing rod 11. As soon as the sensitizer is sprayed out, it is cut and dispersed by the nearby mixing rod 11 to prevent droplet aggregation. At the same time, the up-and-down movement of the mixing rod 11 flips the lower layer of material to the upper layer, which comes into contact with the newly sprayed sensitizer from the nozzle 16, forming a cyclical reinforcement effect of "spraying-stirring-re-spraying".
