Description

Technical Field

[0001] This invention relates to the field of emulsion explosives production, and more particularly to a continuous production equipment and process apparatus for emulsion ammonium nitrate explosives. Background Technology

[0002] With the rapid development of my country's economy, the demand for explosives has increased significantly, leading to substantial growth in the civil explosives industry. Currently, my country's industrial explosives production process has largely achieved mechanization, continuous operation, computer-controlled monitoring, and automation. However, on explosives production lines, the freshly processed emulsion explosive packets require cooling; traditional methods are difficult to control in terms of speed, prone to potential hazards, and have poor cooling effects, necessitating improvement. Furthermore, due to the inherent characteristics of emulsion explosives, their shelf life is easily affected by factors such as temperature and light.

[0003] Patent document CN103755499A discloses a cartridge cooling system for an emulsion explosive production line, characterized by: including an explosive cartridge production device, a cooling water tank, and a drying device; used for cooling and drying the emulsion explosive cartridges during the production process; wherein the explosive cartridge production device is connected to the cooling water tank via a leather conveyor, wherein a conveying device is installed in the cooling water tank, and the conveyor belt corresponding to the conveying device is driven by a motor located at the upper end of the water tank, and multiple cartridge conveying grids are formed on the conveyor belt; wherein the cooling water tank conveys the cartridges to the drying device via another conveying device, and the drying device is equipped with a fan.

[0004] However, in actual use, emulsion explosives have poor cooling effects and are easily affected by various factors during subsequent storage, leading to a shortened lifespan and impacting quality. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a first cooling mechanism and a second cooling mechanism to fully and thoroughly cool the emulsion explosive. At the same time, the heat of the emulsion explosive can be used to melt the phase change energy storage material, thereby realizing the assembly of the fixing parts and further improving the convenience of subsequent storage of the emulsion explosive. This solves the technical problem that the storage life of emulsion explosives is easily reduced due to environmental factors such as temperature changes and light exposure during storage.

[0006] To address the above technical issues, the following technical solution is adopted:

[0007] A continuous production line for emulsified ammonium nitrate explosives includes a fixing component for securing and packaging the emulsified explosives, and further includes:

The heat dissipation tubes are filled with a phase change energy storage material, such as polyethylene glycol.

[0013] Preferably, the conveying assembly includes a first chain conveyor driven by a motor, multiple sets of placement components evenly arranged on the chain conveyor chain, each placement component including a bracket fixedly installed on the chain, a lifting frame vertically slidably connected to the bracket with a spring between the lifting frame and the bracket, and a positioning button arranged on the lifting frame.

[0014] It also includes a guide rail set above the chain conveyor frame to constrain the vertical movement of the lifting frame, and rollers that are in contact with the bottom of the guide rail and set on the lifting frame.

[0015] Preferably, the transfer assembly includes a recovery plate mounted on a lifting frame for holding emulsion explosives, multiple sets of grippers rotatably connected to the recovery plate, a first gear fixedly connected to the rotation shaft of the grippers, and a first rack fixed to the frame and meshing with the first gear.

[0016] Preferably, the melting assembly includes a material pool disposed in the middle of the chain conveyor, a second chain conveyor disposed in the middle of the material pool, a collection plate evenly disposed on the chain of the second chain conveyor, a return trough disposed on the collection plate corresponding to the number of claws on the recovery plate, a strainer fixedly connected above the return trough and provided with a large number of fine mesh holes, a guide pipe disposed below the return trough, and a sliding ring disposed in the middle of the second chain conveyor and slidably connected to all the guide pipes, with a collection trough disposed in the middle of the upper part of the sliding ring;

[0017] It also includes multiple sets of spreaders installed above the recycling plate, which are connected to the material pool to evenly spread the material in the pool.

[0018] Preferably, the cleaning assembly includes multiple swing rods located above the material pool, multiple cleaning scrapers fixed on the swing rods, two first drive shafts driven by chains on a first chain conveyor, drive belts driven by the first drive shafts and slidably connected to both ends of each swing rod, ball bearings rotatably connected to both ends of the swing rods, and wave grooves disposed on both sides of the drive belts and in contact with the ball bearings.

[0019] Preferably, the filling mechanism includes a conveyor belt disposed below the material pool, a conveyor frame disposed on the conveyor belt and used for placing fixed tubes, a rotating rod connected to the conveyor frame by a motor, a second clamping claw disposed on the rotating rod and used for clamping the fixed tubes, and a tightening machine disposed on the conveyor frame for screwing the elastic piston into the heat dissipation tube.

[0020] It also includes a nozzle located below the material pool and connected to the collection tank for filling liquid phase change energy storage material into the heat dissipation pipe, and a rotating stop bar rotatably connected to both sides of the conveyor belt for positioning the conveyor frame.

[0021] Preferably, the second cooling mechanism includes a cooling pool located behind the material pool and a dryer located behind the cooling pool, and also includes an assembly assembly located behind the dryer and for loading the emulsion explosive into the fixed tube.

[0022] Preferably, the assembly includes a lifting platform located below the tail end of the first chain conveyor and driven up and down by an electric cylinder, a push plate located on the side of the upgrading platform away from the conveyor belt and driven by an electric cylinder, a second tightening machine located above the conveyor belt for installing the elastic piston above the fixed tube, and a robotic arm for tightening the cover plate to both sides of the fixed tube.

[0023] As a further preferred embodiment, the production process of the continuous production equipment for emulsified ammonium nitrate explosives includes the following steps:

[0024] Step 1, Preparation: Place the encapsulated emulsion explosive onto the recovery plate, place the fixing tube onto the conveyor frame, and after fixing, place the recovery plate onto the first chain conveyor frame for conveying, and then place the conveyor frame onto the conveyor belt for conveying.

[0025] Step two, the first cooling and filling step: The first chain conveyor moves the recovery plate, which moves above the material pool. Under the action of the gear rack, the emulsion explosive moves and starts to rotate. The spreader evenly spreads the phase change energy storage material in the material pool onto the emulsion explosive. Under the action of the emulsion explosive, it melts and flows through the strainer into the guide pipe. At the same time, during the movement of the conveyor, the first tightening machine screws the elastic piston into the heat dissipation pipe to seal one end of the heat dissipation pipe. The rotating rod rotates to keep the fixed pipe in a vertical state. When it moves below the nozzle, it is stopped by the rotating stop rod, and filling is carried out.

[0026] Step 3, cleaning and secondary cooling: The emulsion explosive continues to move, detaches from the collection plate, and reaches the swing rod. The cleaning scraper on the swing rod contacts the surface of the emulsion explosive. The swing rod moves with the emulsion explosive, swinging back and forth to the left and right to clean the residual phase change energy storage material on the surface of the emulsion explosive. After cleaning, the emulsion explosive enters the cooling pool for thorough cooling.

[0027] Step four, assembly steps: After the filling of the fixed tube is completed, it is moved to the bottom of the second tightening machine to seal and fix the upper end of the cooling tube. The lifting platform rises and then falls to remove the emulsion explosive from the recovery plate. At the same time, the fixed tube rotates again to keep the fixing rod horizontal. The emulsion explosive is pushed into the fixed tube by the push plate. Then, the mechanical arm is used to tighten the cover plates at both ends to complete the assembly.

[0028] The beneficial effects of this invention are:

[0029] (1) In this invention, by setting up a first cooling mechanism and a second cooling mechanism, different cooling media are used to cool the emulsion explosive backward in sequence, so that the cooling efficiency of the emulsion explosive is higher and the cooling effect is more sufficient.

[0030] (2) By setting up a moving mechanism, the entire cooling and assembly process is carried out during the moving process, which can be adapted to the production efficiency of emulsion explosives and reduce the time spent in each step. Through the adjustment of each moving part, the entire work cycle can be made more efficient and interconnected.

[0031] (3) In this invention, the heat carried by the emulsion explosive is recovered and utilized through the first cooling mechanism. The heat carried by the emulsion explosive is used to melt the phase change material and fill the liquid phase change energy storage material. This can effectively avoid a large amount of air mixing in and improve the effect of the fixing parts in subsequent use.

[0032] (4) In this invention, the emulsion explosive is protected by setting a fixing component, which on the one hand avoids damage and leakage of the emulsion explosive during subsequent storage and transportation, and on the other hand, the storage life of the emulsion explosive can be effectively improved by adjusting the temperature inside the fixing tube and blocking the light.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0048] Example 1

[0049] like Figure 1 As shown, a continuous production equipment for emulsified ammonium nitrate explosives is characterized by including a fixing component 001 for fixing and packaging the emulsified explosives, and further comprising:

[0050] The moving mechanism 1 is used to move the emulsion explosive and cooperate with subsequent mechanisms for cooling and assembling the emulsion explosive. The moving mechanism 1 includes a conveying assembly 11 and a transfer assembly 12.

[0051] The first cooling mechanism 2 is disposed at the front end of the moving mechanism 1 and is used to cool the emulsion explosive for the first time. The first cooling mechanism 2 includes a melting component 21 and a cleaning component 22.

[0052] A filling mechanism 3 is disposed below the first cooling mechanism 2 and is used to cooperate with the first cooling mechanism 2 to fill the fixing member 001;

[0053] The second cooling mechanism 4 is located behind the first cooling mechanism 2 and is used to perform secondary cooling of the emulsion explosive while placing the emulsion explosive into the fixing member 001.

[0054] In this embodiment, the emulsion explosive is cooled once by setting the first cooling mechanism 2 and the second cooling mechanism 4, and the phase change energy storage material is melted by the heat of the emulsion explosive itself during cooling. The emulsion explosive is protected by the fixing member 001, and the storage time of the emulsion explosive is increased by using the phase change energy storage material.

[0055] In detail, the emulsion explosive is transported by the moving mechanism 1, so that the emulsion explosive passes through the first cooling mechanism 2 and the second cooling mechanism 4 in sequence for cooling. When the emulsion explosive is cooled by the first cooling mechanism 2, the heat melts the phase change energy storage material and is loaded into the fixing part 001 through the filling mechanism 3. The emulsion explosive is thoroughly cooled by the second cooling mechanism 4 and installed in the fixing part 001.

[0056] It should be noted that by setting the first cooling mechanism 2 and the second cooling mechanism 4 to cool the emulsion explosive in sequence, the emulsion explosive can be thoroughly cooled on the one hand, and the heat carried by the emulsion explosive can be utilized on the other hand, reducing energy consumption.

[0057] It is worth mentioning that when the phase change energy storage material is in a liquid state, the filling process can be carried out. On the one hand, the opening and closing of the filling and the filling volume can be precisely controlled by the valve. On the other hand, the amount of air mixed into the material can be effectively reduced, thereby improving the material's lifespan and performance.

[0058] Furthermore, such as Figure 2 As shown, the fixing component 001 includes a fixing tube 01 for placing emulsion explosive, multiple heat dissipation tubes 02 evenly arranged on the wall of the fixing tube 01, elastic pistons 03 disposed at both ends of the heat dissipation tubes 02, and two octagonal cover plates 04 disposed at both ends of the fixing tube 01 and fixedly connected to the fixing tube 01 by threads. The heat dissipation tubes 02 are filled with a phase change energy storage material, such as polyethylene glycol.

[0059] In this embodiment, the surface of the emulsion explosive is protected by setting a fixing component 001 to prevent leakage of the emulsion explosive during subsequent movement and transportation, and at the same time effectively improve the life of the emulsion explosive.

[0060] In detail, the fixed tube 01 is designed to protect the surface of the emulsion explosive, preventing damage and leakage. It also provides light protection for the emulsion explosive. Meanwhile, the heat dissipation tube 02, which contains phase change energy storage material, controls the temperature inside the fixed tube 01, preventing the emulsion explosive from having a shortened lifespan due to temperature changes and extending its storage time.

[0061] It should be noted that the phase change energy storage material placed inside the heat pipe 02 is a solid-liquid phase change energy storage material, and it needs to be sensitive to room temperature. Materials such as polyethylene glycol (PEG) and polyacrylonitrile (PAN) can be used.

[0062] It is worth mentioning that elastic pistons 03 are installed at both ends of the heat dissipation pipe 02, and the elastic pistons 03 are fastened to both ends of the heat dissipation pipe 02 by threads. The elastic pistons 03 are used to seal both ends of the heat dissipation pipe 02 on the one hand, and to accommodate the volume difference caused by the different states of the phase change energy storage material on the other hand. The octagonal cover plate 04 is provided to facilitate the stacking and placement of emulsion explosives, and also to facilitate the combination and placement during subsequent construction. At the same time, the octagonal cover plate 04 is fastened to the fixed pipe 01 by threads, which facilitates disassembly and further seals the heat dissipation pipe 02.

[0063] Furthermore, such as Figure 3 As shown, the conveying assembly 11 includes a first chain conveyor 111 driven by a motor, multiple sets of placement components 112 evenly arranged on the chain conveyor chain, each placement component 112 including a bracket 113 fixedly installed on the chain, a lifting frame 114 vertically slidably connected to the bracket 113 with a spring between the lifting frame 114 and the bracket 113, and a positioning button 115 provided on the lifting frame 114;

[0064] It also includes a guide rail 116 disposed above the chain conveyor 32 to constrain the vertical movement of the lifting frame 114, and rollers 117 that are in contact with the lower part of the guide rail 116 and disposed on the lifting frame 114.

[0065] In this embodiment, by setting up the placement component 112 and the guide rail 116, and working in conjunction with the first chain conveyor 111, the lifting frame 114 achieves a specific working trajectory, thereby better completing various work tasks.

[0066] In detail, the first chain conveyor 111 drives the support 113 to move. During the movement of the support 113, the lifting frame 114 moves up and down under the constraint of the guide rail 116. The shape of the guide rail 116 is set in accordance with the position of each mechanism so that the lifting frame 114 is at different heights when it moves to different positions.

[0067] It should be noted that the bracket 113 is used to place the recycling plate 121, and every two sets of brackets 113 complete the fixing and movement of one recycling plate 121.

[0068] It is worth mentioning that the installation of the first chain conveyor 111 enables the production line to operate continuously, thereby improving work efficiency.

[0069] Furthermore, such as Figure 4 As shown, the transfer assembly 12 includes a recovery plate 121 mounted on the lifting frame 114 for placing emulsion explosives, multiple sets of grippers 122 rotatably connected to the recovery plate 121, a first gear 123 fixedly connected to the rotating shaft of the grippers 122, and a first rack 124 fixedly mounted on the frame and meshing with the first gear 123.

[0070] In this embodiment, the emulsion explosive is fixed by setting up a recovery plate 121 and a gripper 122. At the same time, the gear rack is used to make the emulsion explosive rotate continuously during the movement, so that the emulsion explosive is cooled more evenly in the subsequent cooling.

[0071] In detail, the emulsion explosive is fixed on the recovery plate 121 by the gripper 122, the recovery plate 121 is placed on the lifting frame 114, the lifting frame 114 drives the recovery plate 121 to move, and the rack and pinion drive gear rotates during the movement of the recovery plate 121, causing the emulsion explosive to rotate.

[0072] It should be noted that the middle part of the recycling plate 121, below the emulsion explosive, is hollowed out.

[0073] It is worth mentioning that the recycling plate 121 is provided with positioning holes that cooperate with positioning buttons 115 to fix the recycling plate 121. At the same time, the placement and removal of the recycling plate 121 can be completed by a robotic arm or manually.

[0074] Furthermore, such as Figure 5 , Figure 6 As shown, the melting assembly 21 includes a material pool 211 located in the middle of the chain conveyor, a second chain conveyor 212 located in the middle of the material pool 211, a collection plate 213 evenly distributed on the chain of the second chain conveyor 212, a return trough 214 on the collection plate 213 corresponding to the number of grippers 122 on the recovery plate 121, a mesh screen 215 fixedly connected above the return trough 214 and provided with a large number of fine mesh holes, a guide pipe 216 located below the return trough 214, and a sliding ring 217 located in the middle of the second chain conveyor 212 and slidably connected to all the guide pipes 216, with a collection trough 218 provided in the middle of the upper part of the sliding ring 217.

[0075] It also includes multiple sets of spreaders 219 installed above the recycling plate 121. The spreaders 219 are connected to the material pool 211 and spread the material in the material pool 211 evenly.

[0076] In this embodiment, by setting up a second chain conveyor 212 and a collection plate 213, and cooperating with the spreading machine 219 to spread the material, the collection plate 213 completes the collection of liquid phase change energy storage material, thereby realizing the utilization of the heat carried by the emulsion explosive itself.

[0077] In detail, the emulsion explosive on the recovery plate 121 moves, the feeder 219 feeds the material, the material falls onto the surface of the emulsion explosive and melts into one piece, and drips through the strainer 215 into the guide pipe 216. Excess solid material continues to fall through the recovery plate 121 and is continuously supplied to the feeder 219. At the same time, the emulsion explosive is in a rotating state, which can make the emulsion explosive cool more evenly.

[0078] It should be noted that by utilizing the heat carried by the emulsion explosive itself, the phase change energy storage material is melted, which facilitates the subsequent filling of the phase change crude energy material and reduces energy utilization. At the same time, it should be emphasized that the material of the guide pipe 216 should be heat-insulating to prevent the internal liquid material from solidifying rapidly and causing blockage. The liquid in the guide pipe flows into the collection groove 218 of the sliding ring 217.

[0079] It is worth mentioning that the second chain conveyor 212 enables the cooling of the emulsion explosive to occur while it is moving, thereby improving the cooling efficiency.

[0080] Furthermore, such as Figure 7 As shown, the cleaning assembly 22 includes multiple swing rods 221 located above the material pool 211, multiple cleaning scrapers 222 fixed on the swing rods 221, two first drive shafts 223 driven by chains on the first chain conveyor 111, drive belts 224 driven by the first drive shafts 223 and slidably connected to both ends of each swing rod 221, ball bearings 225 rotatably connected to both ends of the swing rods 221, and wave grooves 226 disposed on both sides of the drive belts 224 and in contact with the ball bearings 225.

[0081] In this embodiment, by setting the swing rod 221 and the wave groove 226, the swing rod 221 can move back and forth in the left and right directions, thereby cleaning the surface of the emulsion explosive by the cleaning scraper 222, avoiding the residue of too much phase change energy storage material on the surface of the emulsion explosive.

[0082] In detail, the first chain conveyor 111 drives the drive belt 224 to rotate, which in turn drives the swing rod 221 to rotate cyclically. When the recovery plate 121 moves below the swing rod 221, the cleaning scraper 222 on the swing rod 221 adheres to the surface of the emulsion explosive and moves backward together with the emulsion explosive. During the movement, the swing rod 221 slides left and right due to the presence of the wave groove 226. The multiple cleaning scrapers 222 cooperate with the rotation of the emulsion explosive itself to clean the surface of the emulsion explosive.

[0083] It should be noted that the contact surface between the cleaning scraper 222 and the emulsion explosive should be made of a relatively soft felt material to avoid damage and leakage of the emulsion explosive during the cleaning process.

[0084] Furthermore, such as Figure 8 , Figure 9 As shown, the filling mechanism 3 includes a conveyor belt 31 disposed below the material pool 211, a conveyor frame 32 disposed on the conveyor belt 31 and conveyed by a transmission belt for placing the fixed tube 01, a rotating rod 33 rotatably connected to the conveyor frame 32 by a motor, a second gripper 34 disposed on the rotating rod 33 for clamping the fixed tube 01, and a tightening machine 35 disposed on the conveyor frame 32 for screwing the elastic piston 03 into the heat dissipation pipe 02.

[0085] It also includes a nozzle 36 located below the material pool 211 and connected to the collection tank 218 for filling liquid phase change energy storage material into the heat dissipation pipe 02, and a rotating stop bar 37 rotatably connected to both sides of the conveyor belt 31 for positioning the conveyor frame 32.

[0086] In this embodiment, the fixed tube 01 is fixed by setting the conveyor frame 32, and the elastic piston 03 is fixed by the tightening machine 35. The fixed tube 01, which has completed the initial assembly, is then filled.

[0087] In detail, the fixed tube 01 is placed on the conveyor frame 32, and the second gripper 34 on the rotating rod 33 clamps the fixed tube 01. At the same time, the elastic piston 03 is pre-placed on the tightening machine 35. The elastic piston 03 is screwed into one end of the heat dissipation tube 02 to complete the sealing of that end of the heat dissipation tube 02. After moving to below the nozzle 36, the rotating rod 33 rotates to make the fixed rod rotate from the horizontal direction to the vertical direction. The rotating stop rod 37 stops the conveyor frame 32, and the nozzle 36 begins filling. After filling is completed, the rotating stop rod 37 rotates, and the conveyor frame 32 continues to move backward to complete the filling.

[0088] It should be noted that a groove can be provided at the tail end of the elastic piston 03, and the elastic piston 03 can be tightened by an electric screw tightening machine 35.

[0089] Furthermore, such as Figure 10As shown, the second cooling mechanism 4 includes a cooling pool 41 disposed behind the material pool 211 and a dryer 42 disposed behind the cooling pool 41, and also includes an assembly assembly 43 disposed behind the dryer 42 and used to load the emulsion explosive into the fixed tube 01.

[0090] In this embodiment, the emulsion explosive is further cooled by setting up a cooling pool 41 and a dryer 42, and then assembled after cooling is completed.

[0091] In detail, the emulsion explosive is conveyed into the cooling pool 41 by the first chain conveyor 111, where it is thoroughly cooled and then air-dried after exiting the cooling pool 41 to prevent water residue.

[0092] It should be noted that the liquid in cooling pool 41 is cooling water.

[0093] Furthermore, such as Figure 11 As shown, the assembly component 43 includes a lifting platform 431 driven up and down by an electric cylinder and located below the tail end of the first chain conveyor 111; a push plate 432 driven by an electric cylinder and located on the side of the upgrading platform away from the conveyor belt 31; a second tightening machine 433 located above the conveyor belt 31 and used to install the elastic piston 03 above the fixed tube 01; and a mechanical arm used to tighten the cover plate 04 to both sides of the fixed tube 01.

[0094] In this embodiment, the transfer of emulsion explosive is completed by setting up a lifting platform 431 and a pusher plate 432, and the emulsion explosive is assembled with the fixed tube 01.

[0095] In detail, the lifting platform 431 rises, sends the emulsion explosive onto the recovery plate 121, and then descends. Using the gap on the recovery plate 121, the emulsion explosive is moved to the lower part. At the same time, the second tightening machine 433 seals the upper end of the already filled fixed tube 01. After the process is completed, the rotating rod 33 rotates again to return the fixed rod to the horizontal state. The push rod pushes the emulsion explosive into the fixed tube 01. Then, the mechanical arm tightens the cover plate 04 at both ends of the fixed tube 01.

[0096] It should be noted that after the emulsion explosive is removed from the recovery plate 121, it is also necessary to manually or mechanically remove the recovery plate 121 from the first chain conveyor 111 and send it to the beginning of the production line for reuse.

[0097] Example 2

[0098] like Figure 12 , Figure 13As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0099] The production process of the continuous production equipment for emulsified ammonium nitrate explosives includes the following steps:

[0100] Step 1, Preparation: Place the encapsulated emulsion explosive onto the recovery plate 121, place the fixing tube 01 onto the conveyor frame 32, and after fixing, place the recovery plate 121 onto the first chain conveyor frame 32 for conveying, and place the conveyor frame 32 onto the conveyor belt 31 for conveying.

[0101] Step two, the first cooling and filling step: the first chain conveyor 32 drives the recovery plate 121 to move. The recovery plate 121 moves above the material pool 211. Under the action of the gear rack, the emulsion explosive moves and starts to rotate. The spreader 219 evenly spreads the phase change energy storage material in the material pool 211 onto the emulsion explosive. Under the action of the emulsion explosive, it melts and flows through the strainer 215 into the guide pipe 216. At the same time, during the movement of the conveyor 32, the first tightening machine 35 screws the elastic piston 03 into the heat dissipation pipe 02 to seal one end of the heat dissipation pipe 02. The rotating rod 33 rotates to keep the fixed pipe 01 in a vertical state. When it moves below the nozzle, it is stopped by the rotating stop rod 37, and filling is carried out.

[0102] Step 3, cleaning and secondary cooling: The emulsion explosive continues to move, detaches from the collection plate 213, and reaches the swing rod 221. The cleaning scraper 222 on the swing rod 221 contacts the surface of the emulsion explosive. The swing rod 221 moves with the emulsion explosive, swinging back and forth to the left and right while moving to clean the phase change energy storage material remaining on the surface of the emulsion explosive. After cleaning is completed, the emulsion explosive enters the cooling pool 41 for thorough cooling.

[0103] Step four, assembly steps: The fixed tube 01 after filling is moved to the bottom of the second tightening machine 433 to seal and fix the upper end of the cooling tube. The lifting platform 431 rises and then falls to move the emulsion explosive off the recovery plate 121. At the same time, the fixed tube 01 rotates again to keep the fixing rod horizontal. The emulsion explosive is pushed into the fixed tube 01 by the push plate 432. Then, the mechanical arm is used to tighten the cover plates 04 at both ends to complete the assembly.

[0104] In the description of this invention, it should be understood that the terms "front and back", "left and right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

9. The production process of any one of the continuous production equipment for emulsified ammonium nitrate explosives according to claims 1-8, characterized in that, Includes the following steps: Step 1, preparation steps: Place the encapsulated emulsion explosive on the recycling plate (121), place the fixing tube (01) on the conveyor frame (32), after fixing, place the recycling plate (121) on the first chain conveyor frame (32) for conveying, and place the conveyor frame (32) on the conveyor belt (31) for conveying. Step two, the first cooling and filling step, the first chain conveyor (32) drives the recovery plate (121) to move. The recovery plate (121) moves above the material pool (211). Under the action of the gear rack, the emulsion explosive moves and starts to rotate. The spreader (219) spreads the phase change energy storage material in the material pool (211) evenly onto the emulsion explosive. Under the action of the emulsion explosive, it melts and flows into the guide pipe (216) through the strainer (215). At the same time, during the movement of the conveyor (32), the first tightening machine (35) screws the elastic piston (03) into the heat dissipation pipe (02) to seal one end of the heat dissipation pipe (02). The rotating rod (33) rotates to keep the fixed pipe (01) in a vertical state. When it moves below the nozzle, it is stopped by the rotating stop bar (37) and filling is carried out. Step 3, cleaning and secondary cooling: The emulsion explosive continues to move, detaches from the collection plate (213), and reaches the swing rod (221) for lowering. The cleaning scraper (222) on the swing rod (221) contacts the surface of the emulsion explosive. The swing rod (221) moves with the emulsion explosive and swings back and forth to the left and right while moving to clean the residual phase change energy storage material on the surface of the emulsion explosive. After cleaning is completed, the emulsion explosive enters the cooling pool (41) for thorough cooling. Step four, assembly steps: The fixed tube (01) after filling is moved to the bottom of the second tightening machine (433) to seal and fix the upper end of the cooling tube. The lifting platform (431) rises and then falls to move the emulsion explosive off the recovery plate (121). At the same time, the fixed tube (01) rotates again to keep the fixing rod horizontal. The emulsion explosive is pushed into the fixed tube (01) by the push plate (432). Then, the mechanical arm is used to tighten the cover plates (04) at both ends to complete the assembly.
