Description

Technical Field

[0001] The invention relates to the technical field of emulsion explosive production, in particular to a mixing device for emulsion explosive production. Background Art

[0002] In the production of emulsion explosives, the mixing process is critical to ensuring product quality and performance. Existing emulsion explosive mixing devices typically use a single agitator blade, which only stirs the raw materials in the middle and upper portions of the mixing tank, but struggles to effectively stir the bottom materials. This results in insufficient and uneven mixing of the bottom materials with the middle and upper portions, directly impacting the quality stability and explosive performance of the emulsion explosive.

[0003] Furthermore, traditional mixing devices lack a real-time quality detection mechanism, making it impossible to promptly monitor the state of raw materials during the mixing process. Manual sampling and analysis are often required after mixing is complete. If substandard raw materials are found, not only is a significant amount of time and raw materials wasted, but the failure to promptly remove substandard raw materials can also lead to a decline in the quality of the entire batch of products, increasing production costs and posing safety risks. Furthermore, existing devices struggle to precisely control the mixing state and temperature during the mixing process, making it impossible to adjust mixing parameters based on real-time monitoring data. This results in long mixing times and low efficiency, making it difficult to meet the efficient and precise production requirements of modern emulsion explosives.

[0004] Therefore, there is an urgent need for a mixing device for emulsion explosive production that can solve the above problems, so as to achieve sufficient and uniform mixing of raw materials, improve the efficiency and accuracy of quality inspection, accurately control the mixing process, shorten the mixing time, and improve production efficiency and product quality.

[0036] It also includes an off-axis drive mechanism, which is arranged on the top of the mixing tank 1 and is used to drive the hollow stirring shaft 101 to rotate; the off-axis drive mechanism includes a stirring motor 4, a mounting plate 401, a first gear 41 and a second gear 42, the mounting plate 401 is fixedly mounted on the top of the fixed outer frame 2, the stirring motor 4 is fixedly mounted on one side of the mounting plate 401, the output end of the mounting plate 401 is fixedly mounted on the first gear 41, and the second gear 42 is fixedly sleeved on the top of the surface of the hollow stirring shaft 101, and the first gear 41 and the second gear 42 are engaged with each other. The mounting plate 401 can cooperate with the fixed outer frame 2 to suspend and fix the stirring motor 4, thereby making it easy to utilize the hollowing out around the top of the fixed outer frame 2 so that the feeding pipe on the top of the mixing tank 1 can be easily connected to different feeding pipes and dosing pipes, thereby facilitating the addition of various additives, oil-phase materials and emulsifiers required for emulsion explosives. When the stirring motor 4 is started, the output end drives the first gear 41 to rotate, and the first gear 41 drives the second gear 42 engaged with it to rotate, and then the second gear 42 drives the hollow stirring shaft 101 to rotate to stir the materials.

[0037] The real-time rotating sampling mechanism is arranged on one side of the top of the mixing tank 1 and is used to extract the liquid inside the mixing tank 1 in real time for sampling and detection; the real-time rotating sampling mechanism includes a sampling box 5, an extrusion cylinder 51, a sampling cylinder 52, a centrifugal pump 54, a sealing plate 55, an image recognition camera 56, a transparent acrylic plate 57, a temperature sensor 58 and an electromagnetic sampling component. The sampling box 5 is connected to the side of the top of the mixing tank 1 away from the stirring motor 4, the sampling cylinder 52 is fixedly installed on the bottom of the sampling box 5 away from the stirring motor 4, the extrusion cylinder 51 is fixedly installed on the side of the top of the sampling box 5 close to the stirring motor 4, a partition is fixedly installed at the inner center of the sampling box 5, the side of the partition away from the stirring motor 4 is fixedly installed with the centrifugal pump 54, and the input end of the centrifugal pump 54 passes through the partition and extends to the sampling box 5 The bottom of the sampling box 5 is fixedly mounted on the top of the inner wall of the sampling box 5, close to the extrusion cylinder 51. The sealing plate 55 is slidably mounted on the side of the bottom of the sampling box 5 away from the sample cylinder 52. The output end of the sample cylinder 52 passes through the sampling box 5 and is fixedly mounted on the sealing plate 55. The transparent acrylic plate 57 is slidably mounted on the inner wall of the sampling box 5, close to the stirring motor 4. The top of the transparent acrylic plate 57 is fixedly mounted on the output end of the extrusion cylinder 51. The image recognition camera 56 has a built-in image sensor, an image signal sensor, an image recognition algorithm and a communication interface. The electromagnetic sampling component is arranged on the surface of the hollow stirring shaft 101 and is used to extract the mixed liquid at different liquid levels. The temperature sensor 58 is fixedly embedded in the top of the sealing plate 55 and is electrically connected to the external controller through a wire.

[0038] Since the sampling box 5 is connected to the top of the mixing tank 1, when sampling, the electromagnetic sampling component of the corresponding level is started according to the stirring level to be sampled, and the centrifugal pump 54 is turned on at the same time to allow the material to be sucked into the interior of the sampling box 5 and to be on the side of the partition close to the stirring motor 4, which is connected to the mixing tank 1 below. When sampling, the sample cylinder 52 is started to push the sealing plate 55 to the bottom of the inner wall of the closed sampling box 5 to prevent the material from falling. Subsequently, the transparent acrylic plate 57 is driven downward by starting the output end of the extrusion cylinder 51, so that the transparent acrylic plate 57 compacts the material between the transparent acrylic plate 57 and the sealing plate 55, and then the image recognition camera 56 has a built-in image sensor to record the image, and then the image recognition algorithm is used to identify the current state of material mixing, density, and the temperature information of the temperature sensor 58, and the material mixing situation. If the image information is insufficient, the mixed product result is then Continue stirring, and if the temperature is lower than the corresponding threshold, the temperature of the material inside the mixing tank 1 is adjusted by the temperature control component. If the image information is consistent, the pneumatic discharge valve 3 can be opened in time to discharge the material to improve production efficiency. When the detection is completed, the sample discharge cylinder 52 is started again to retract the sealing plate 55, so that there is a gap at the bottom of the inner wall of the sampling box 5, and the sample material taken out falls into the interior of the mixing tank 1. When retracting, the material on the temperature sensor 58 will also be scraped off by the bottom of the partition to avoid affecting the next detection effect. Then start the extrusion cylinder 51 to drive the transparent acrylic plate 57 toward the sealing plate 55 so that the transparent acrylic plate 57 is above the sealing plate 55. At this time, start the sample discharge cylinder 52 again to scrape off the material residue at the bottom of the transparent acrylic plate 57. After scraping off the residue, the extrusion cylinder 51 drives the transparent acrylic plate 57 to reset upward to facilitate the next sampling detection.

The solenoid valve 1012 is connected to the end of the sampling and stirring tube 1011 away from the hollow stirring shaft 101. The conductive inner ring of the conductive slip ring 531 is fixedly installed with the hollow stirring shaft 101, and the conductive outer ring of the conductive slip ring 531 is connected to the external power supply through a wire. The high-pressure rotary sealing joint 53 is connected to the top of the hollow stirring shaft 101, and the inner ring of the conductive slip ring 531 is electrically connected to multiple groups of solenoid valves 1012 through a wire. The end of the high-pressure rotary sealing joint 53 away from the hollow stirring shaft 101 is connected to the bottom of the sampling box 5 close to the stirring motor 4.

[0040] The sampling stirring tube 1011 can rotate along with the hollow stirring shaft 101 to stir the material inside the mixing tank 1. At the same time, during the stirring process, the solenoid valve 1012 can be started to facilitate the extraction of materials in the corresponding layer after the centrifugal pump 54 is started. The high-pressure rotary sealing joint 53 can ensure that the material drawn into the sampling stirring tube 1011 stably enters the interior of the sampling box 5 while the hollow stirring shaft 101 rotates, without affecting the stirring work, and can obtain the stirring conditions in the mixing tank 1 in real time, thereby improving the mixing efficiency. In addition, the sampling stirring tube 1011 can transmit external power to the rotating sampling stirring tube 1011 through the conductive inner ring of the conductive slip ring 531, so that the sampling stirring tube 1011 can be started and used during rotation.

The temperature control coil 102 is coiled on the inner wall of the mixing tank 1, one end of the input pipe 1021 is connected to one end of the temperature control coil 102, and one end of the output tank 1022 is connected to the other end of the temperature control coil 102. The input pipe 1021 and the output tank 1022 are both connected to an external cold source and a heat source through an electromagnetic three-way valve;

[0050] When the temperature is controlled by the temperature information of the temperature sensor 58, when the temperature is lower than the threshold, the input pipe 1021 and the output tank 1022 are connected to the heat source, and the cold and hot source transmission path is switched by the external electromagnetic three-way valve. The cold and hot source switching path diagram is shown in FIG. Figure 11 As shown, the heat source liquid is then circulated inside the temperature control coil 102 to heat the material inside the mixing tank 1, and similarly, the cold source is switched to cool the material inside the mixing tank 1.

[0051] Working principle: Raw materials and additives are added through the feeding tube, and then the material stirring is started through the staggered shaft drive mechanism: the stirring motor 4 is installed on the mounting plate 401, and the first gear 41 and the second gear 42 are engaged and driven to drive the hollow stirring shaft 101 to rotate. The hollow stirring shaft 101 drives the sampling stirring tube 1011 fixed on its surface to perform preliminary stirring on the material in the mixing tank 1, so that the material is preliminarily mixed in the tank;

[0052] The real-time rotary sampling mechanism monitors the mixing state: according to the stirring level to be sampled, the solenoid valve 1012 on the sampling stirring tube 1011 of the corresponding level is started, and the centrifugal pump 54 is turned on at the same time. The material is sucked into the side of the partition in the sampling box 5 close to the stirring motor 4 through the sampling stirring tube 1011, the hollow stirring shaft 101 and the high-pressure rotary sealing joint 53. The sampling cylinder 52 pushes the sealing plate 55 to close the bottom of the sampling box 5 to prevent the material from falling; the extrusion cylinder 51 drives the transparent acrylic plate 57 to press down to compact the material. The image recognition camera 56 uses the image sensor to record the material image, and combines the temperature information detected by the temperature sensor 58 to analyze the material mixing state, density and other parameters through the image recognition algorithm. If the test result does not meet the requirements, continue stirring; if it meets the requirements, open the pneumatic discharge valve 3 to discharge the material. After the test is completed, the sampling cylinder 52 and the extrusion cylinder 51 cooperate to remove the residual material in the sampling box 5 to prepare for the next sampling;

[0053] Timed start and intelligent monitoring strategy, timed sampling mechanism: The real-time rotary sampling mechanism supports flexible timed start function. Users can preset sampling intervals through an external controller, such as automatic sampling and detection every 5 minutes or 10 minutes. The system's built-in timing module will strictly trigger the sampling process according to the set time, ensuring periodic and regular monitoring of material status during the emulsion explosive mixing process. This timed sampling method can effectively capture material changes at different stages of the mixing process and promptly identify potential mixing problems.

[0054] Intelligent trigger sampling: In addition to timed sampling, the system also has an intelligent trigger mechanism. When the cumulative stirring time of the hollow stirring shaft 101 reaches a specific value, such as continuous stirring for 30 minutes, or when the current of the stirring motor 4 fluctuates abnormally, indicating a change in stirring resistance, which may indicate uneven mixing or agglomeration of materials, the system will automatically start the sampling program. In addition, if different batches of raw materials are added during the production process, sampling and testing will be triggered immediately to ensure that the mixing effect of each batch of raw materials can be promptly evaluated.

[0055] Stirring level and multi-dimensional monitoring, precise layered sampling: Since the sampling stirring tubes 1011 are staggered in six groups on the hollow stirring shaft 101, layered sampling of materials at different liquid levels in the mixing tank 1 can be achieved. When starting sampling, single-layer sampling or multi-layer combined sampling can be selected according to actual needs. For example, when it is suspected that the bottom material is not mixed sufficiently, the solenoid valves 1012 of the bottom two layers of sampling stirring tubes 1011 can be started separately for targeted sampling; if a comprehensive evaluation of the mixing effect is required, the multi-layer sampling stirring tubes 1011 can be opened in sequence to obtain material samples at different layers, providing richer data for mixing state analysis;

[0056] Mixing mode associated monitoring: Considering that a variety of mixing modes may be used in actual production, the sampling mechanism can be linked with the mixing mode. When conventional uniform-speed mixing is used, the system samples according to the established timing or intelligent triggering rules; if it switches to variable-speed mixing, such as first high-speed mixing to initially disperse the material, and then low-speed mixing to achieve fine mixing, sampling will be automatically started at different mixing speed switching nodes to monitor the impact of changes in mixing speed on material mixing. In addition, for intermittent mixing, the system will pause after a period of stirring and then continue stirring. At each start and pause of stirring, the system will sample to analyze the effect of intermittent operation on the uniformity of material mixing;

[0057] Mixing state analysis and feedback optimization, multi-parameter comprehensive analysis: The image recognition camera 56 can not only identify visual information such as the material's appearance and particle distribution, but can also combine with deep learning algorithms to quantitatively evaluate the material's mixing uniformity. For example, by analyzing the proportion and distribution of different color or texture areas in the image, the mixing degree of each component in the emulsion explosive can be determined. At the same time, the temperature data obtained by the temperature sensor 58 is combined with the image information to further analyze the impact of temperature on the mixing process. For example, if the temperature in a certain area is too high, it may cause the emulsifier to fail or some components to react prematurely, affecting the mixing quality. The system will issue a timely warning.

[0058] Feedback adjustment mechanism: Based on sampling test results, the system can automatically adjust the mixing parameters. If uneven mixing is detected, the mixing time can be appropriately extended or the speed of the stirring motor 4 can be increased. If the temperature does not meet the requirements, the temperature control component will strengthen the temperature adjustment to ensure that the materials are mixed under optimal conditions. In addition, the system can also compare and analyze historical test data with current data to continuously optimize the mixing process parameters, form a closed-loop control, and gradually improve the mixing quality and production efficiency of emulsion explosives.

[0059] Abnormal situation handling and sampling failure response: During the sampling process, if the centrifugal pump 54 fails to extract materials normally, or the solenoid valve 1012 fails to open / close normally, the system will immediately issue an alarm and stop the relevant sampling operation. At the same time, the system will attempt to perform fault self-tests, such as checking circuit connections and pump blockage, and feedback the fault information to the operator to facilitate rapid location and repair of the problem;

[0060] Extreme situation handling: When the image recognition camera 56 detects that the material has severe agglomeration, stratification or other extreme abnormal conditions, or the temperature sensor 58 detects that the temperature exceeds the safety threshold, the system will automatically trigger the emergency shutdown procedure and open the pneumatic discharge valve 3 to discharge the unqualified material from the mixing tank 1 to prevent safety accidents. In addition, the system will also record the time, location and specific circumstances of the abnormality to provide a basis for subsequent accident analysis and process improvement;

[0061] The linkage flipping mechanism strengthens the mixing of the bottom materials: when the hollow stirring shaft 101 rotates, the reduction gear 2 162 is driven to rotate through the linkage block 11, and the reduction gear 1 16, the limiting shaft 161, the reduction bevel gear 2 15, the reduction bevel gear 1 14, the worm 13 and the worm wheel 141 are sequentially driven to realize the reduction transmission of the flipping longitudinal shaft 1051; the flipping longitudinal shaft 1051 drives the first bevel gear 1052 and the second bevel gear 1053 to rotate, and the first bevel gear 1052 drives the gear ring 10581 through the fourth bevel gear 1059, the linkage shaft 10582 and the flipping drive gear 1058, so that the drive ring sleeve 104 rotates, driving the arc-shaped connecting frame 1054 to move in a circular manner around the flipping longitudinal shaft 1051; at the same time, the second bevel gear 1053 drives the third bevel gear 1056 to make the flipping stirring rod 1055 rotate, flipping the material at the bottom of the mixing tank 1, and promoting full mixing of the bottom and middle materials;

[0062] The temperature control component adjusts the mixing temperature: the temperature sensor 58 feeds back the detected material temperature information to the external controller. When the temperature is lower than the threshold, the input pipe 1021 and the output tank 1022 are connected to the heat source through the electromagnetic three-way valve, and the heat source liquid circulates in the temperature control coil 102 to heat the material in the mixing tank 1; when the temperature is higher than the threshold, the cold source is switched to cool the material to ensure that the material is mixed at an appropriate temperature.
