[0030] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] like Figure 1 The production system shown is for producing detonating explosives and includes batching equipment, chemical reaction and washing equipment, drying and packaging equipment, and waste liquid treatment equipment.

[0032] like Figures 1 to 3 As shown, the batching equipment includes several raw material batching tanks 1, a metering pump 2 connected to the raw material batching tanks 1, several auxiliary material batching tanks 3, a peristaltic pump 4 connected to the auxiliary material batching tanks 3, and a water bath heating tank 5. Different raw materials are dissolved in different raw material batching tanks 1, heated to the temperature required by the production process, and then sent to the reaction vessel 7 by the metering pump 2. Auxiliary materials are dissolved in auxiliary material batching tanks 3, heated to the temperature required by the production process, and then sent to the reaction vessel 7 by the peristaltic pump 4. Some auxiliary material batching tanks 3 are equipped with a stirrer, while others are not, to adapt to different raw material dissolution and storage requirements. The water bath heating tank 5 is used to dissolve and prepare trace amounts of additives in containers such as beakers. During raw material batching, the raw material solids are weighed and placed in the raw material batching tanks 1. The required amount of deionized water is calculated, and the water volume is accurately injected. After water injection, the heating and stirring system is automatically started. After stirring to the process-specified time and temperature, a sample is taken for quality inspection to obtain the raw material solution. The auxiliary material preparation tank 3 also completes the preparation in the same way.

[0033] like Figure 4As shown, the chemical reaction washing equipment includes a support frame 6, several sets of first and second bearing seats connected to the support frame 6, several reaction vessels 7 connected to one set of first and second bearing seats via a rotating shaft, a tilting motor 8 connected to the support frame 6 and driven by the rotating shaft, a discharge valve connected to the bottom of the reaction vessel 7, a stirrer 9 connected to the open end of the reaction vessel 7, a suction filter hopper 10 located on one side of the reaction vessel 7 and connected to the support frame 6, a heater 11 connected to the support frame 6, a feeding cylinder 12 connected to the support frame 6, a raw material injector 13 connected to the telescopic rod of the feeding cylinder 12, a pH sensor and a temperature sensor 14 connected to the reaction vessel 7, and a filter workbench 15 located below the reaction vessel 7 and connected to the support frame 6. The filter workbench 15 is connected to the lower part of the suction bucket 16, the vacuum buffer tank 17 is connected to the suction bucket 10 and the suction bucket 16 through a pipe, the conveyor 21 is located on one side of the filter workbench 15 and connected to the support 6, the medicine tray 22 can run at different work positions, the first conveying mechanism 23 can change the position of the medicine tray 22 between the filter workbench 15 and the conveyor 21, the washing and dehydration mechanism 24 is located on one side of the conveyor 21 and connected to the support 6 and the conveyor 21, and the second vacuum buffer tank 25 is connected to the liquid outlet of the washing and dehydration mechanism 24 through a pipe.

[0034] The tilting motor 8 is connected to the rotating shaft drive through the gearbox, and the raw material injector 13 is connected to the metering pump 2 and peristaltic pump 4 at the feeding end through the pipeline, which facilitates remote control of feeding.

[0035] After pre-production preparations are completed, the chemical reaction system is started. The rotating motor 8 turns the opening of the reactor 7 upwards, and the extension rod of the feeding cylinder 12 extends to push the raw material injector 13 above the reactor 7. After the metering pump 2 and peristaltic pump 4 are started, the reactants and auxiliary materials are injected into the reactor 7 through the pipeline and the raw material injector 13. After the reactants are mixed in the reactor 7, a chemical reaction is carried out to generate the detonating explosive. If necessary, a specified amount of reaction base liquid is injected into the reactor 7 before injecting the reactants and auxiliary materials, and the stirring is started. The water bath is heated to the reaction temperature. During the reaction, the process conditions are controlled by detecting the temperature and pH value of the reaction liquid. The heater 11 is used to heat the reactants or auxiliary materials entering the reactor 7. After the reaction is completed, the product is placed into the reagent tray 22 on the filter workbench 15 through the discharge valve for filtration and dehydration. The liquid produced by filtration is adsorbed into the vacuum buffer tank 17 under vacuum. After filtration and dehydration, the reagent tray 22 is transferred to the conveyor 21 via the first conveyor mechanism 23, and then sent to the washing and dehydration unit 24 for washing and dehydration. When the reactor 7 needs cleaning, the material in the reactor 7 is emptied through the discharge valve, and then a detonating liquid is injected into the reactor 7 to reach the reaction liquid level. The reactor is heated and stirred to complete the detonation, and then the detonating liquid is sent to the detonation tank 56. The extension rod of the feeding cylinder 12 retracts so that the raw material injector 13 is no longer above the reactor 7, the discharge valve is closed, and the tilting motor 8 turns the open end of the reactor 7 towards the top of the suction filter 10 to clean the reactor 7, remove the adhering substances in the reactor 7, and avoid the acid from affecting the quality of the next production. The adhering substances are filtered in the suction filter 10, the filtrate is collected in the vacuum buffer tank 17, and the filter residue is transferred into the reagent tray 22.

[0036] like Figure 1 and Figure 5 As shown, the washing and dehydration mechanism 24 includes a second support 57 connected to the support 6 and the conveyor 21, a washing worktable 58 connected to the second support 57, a second suction bucket 59 connected to the lower part of the washing worktable 58, a third vacuum buffer tank 60 connected to the second suction bucket 59 through a pipe, a nozzle moving cylinder 18 connected to the second support 57, a nozzle 19 connected to the telescopic rod of the nozzle moving cylinder 18, a cleaning fluid storage and pumping mechanism 20 that supplies cleaning fluid to the nozzle 19, and a fourth conveying mechanism 61 that can switch the position of the medicine tray 22 between the conveyor 21 and the washing worktable 58.

[0037] After conveyor 21 delivers the explosive charge tray 22 to the washing and dehydration mechanism 24, the fourth conveying mechanism 61 transfers the explosive charge tray 22 from conveyor 21 to the washing workbench 58. The telescopic rod of the nozzle moving cylinder 18 extends, aligning the nozzle 19 with the explosive charge tray 22. The nozzle 19 first sprays water to rinse and soak the explosive charge in the tray 22. Then, the vacuum suction mechanism is activated to draw the filtrate from the suction hopper to the third vacuum buffer tank 60. After the water is drained, the vacuum suction mechanism is closed, and compressed air is introduced through the nozzle 19 to dry the material inside the nozzle and the explosive charge tray 22. Then, alcohol is introduced into the nozzle to rinse and soak the explosive charge in the tray. Finally, the vacuum suction mechanism is activated again to complete the dehydration process. By spraying deionized water and alcohol (if necessary) through the nozzle, the pH of the explosive charge in the tray is first adjusted to neutral to prevent moisture absorption during subsequent storage. Using alcohol for dehydration improves the drying efficiency and flowability of the explosive charge during use.

[0038] like Figure 1 and Figure 8 As shown, the drying and packaging equipment includes a dryer 26 located on one side of the conveyor 21 and connected to the conveyor 21, a second conveying mechanism 27 capable of changing the position of the medicine tray 22 between the conveyor 21 and the dryer 26, a screening and boxing machine 28 located on one side of the conveyor 21 and connected to the conveyor 21, a third conveying mechanism 29 capable of changing the position of the medicine tray 22 between the conveyor 21 and the screening and boxing machine 28, a second conveyor 30 connected to the screening and boxing machine 28, and a plurality of finished medicine boxes 31 placed on the second conveyor 30.

The equipment includes a waste medicine box 41, a medicine tray mounting frame 42 connected to the multi-stage sieve mounting base 33, a rotating shaft 43 connected to the medicine tray mounting frame 42, a rotating cylinder 44 with its two ends connected to the medicine tray mounting frame 42 and the rotating shaft 43 respectively, a rotating frame 45 connected to the rotating shaft 43, a lifting cylinder 46 connected to the frame 32, and a dust cover 47 connected to the piston rod of the lifting cylinder; the drying and packaging equipment also includes a metering mechanism mounting frame 48 connected to the frame 32 or the second conveyor 30, a metering lifting cylinder 49 connected to the metering mechanism mounting frame 48, a weighing sensor 50 connected to the telescopic rod of the metering lifting cylinder 49, and a medicine box weighing top block 51 connected to the weighing sensor 50.

[0040] The multi-stage sieve 34 is a two-layer oscillating sieve. A linear reciprocating cylinder 35 drives the multi-stage sieve 34 to oscillate back and forth. The upper layer separates coarse particles, and the lower layer separates fine powder. The residue in the lower layer is the qualified product. Unqualified drugs are sent to a waste drug collector containing detonating liquid for final manual disposal.

[0041] In operation, conveyor 21 delivers the dried explosive tray 22 to the screening and packaging machine 28. The third conveying mechanism 29 moves the explosive tray 22 from conveyor 21 to the explosive tray mounting frame 42. After the explosive tray 22 is mounted on the mounting frame 42, the lifting cylinder 46 retracts its piston rod to lower and cover the dust cover 47. The linear reciprocating cylinder 35 is activated, and the rotary cylinder 44 is operated to pour the detonating explosive from the explosive tray 22 into the upper layer of the multi-stage sieve 34, completing the screening operation. The qualified product after screening enters the fine explosive box 36. During packaging, the telescopic rod of the metering lifting cylinder 49 extends, and the weighing sensor 50 is raised and in working condition, controlling the opening of the pneumatic discharge valve 37 to complete the packaging.

The wastewater recovery devices include a sedimentation tank 54 for holding the liquid output from the vacuum buffer tank 17 or the second vacuum buffer tank 25, and an evaporation tank 55 for evaporating the clarified liquid output from the sedimentation tank 54. After the wastewater settles and separates in the sedimentation tank 54, the clarified liquid output from the sedimentation tank 54 is evaporated in the evaporation tank 55. The solids or concentrated liquid in the sedimentation tank 54 and the evaporation tank 55 are collected separately and then treated. All wastewater from the production line is collected, detonated, and then sent to the sedimentation tank.

The piston rod of the lifting cylinder 64 extends, allowing the clamping robot 66 to reach both sides of the medicine tray 22. Then, the clamping cylinder 65 retracts, causing the clamping robot 66 to clamp the medicine tray 22. The piston rod of the lifting cylinder 64 retracts, lifting the medicine tray 22. The positioning and conveying mechanism 63 moves the medicine tray 22 above the target station. The piston rod of the lifting cylinder 64 extends, causing the medicine tray 22 to descend. After the medicine tray 22 is lowered and connected to the target station, the clamping cylinder 65 causes the clamping robot 66 to open, releasing the medicine tray 22. The piston rod of the lifting cylinder 64 retracts, causing the clamping robot 66 to lift. The positioning and conveying mechanism 63 moves the lifting cylinder 64, the clamping cylinder 65, and the clamping robot 66 out of the area above the target station.
