Description
Technical Field
[0001] The invention relates to the technical field of production equipment for explosives, and in particular to a continuous chemical combination reactor. Background Art
[0002] Explosives are the initial source of energy for all civilian blasting equipment and ammunition detonators. The main varieties include dinitrodiazophenol (DDNP), tricarbohydrazide zinc perchlorate (GTX), tricarbohydrazide cadmium perchlorate (GTG), nickel nitrate hydrazine (NHN), dextrin lead azide (LA), lead styphnate (LS), basic lead picrate and lead azide double salt (K·D), lead azide and lead styphnate co-precipitate (D·S), etc. Since explosives are highly sensitive and easy to ignite and explode, accidental explosion accidents are very likely to occur during the production process, which is very dangerous. As one of the most dangerous explosive items that must be used in the production of civilian blasting equipment and the defense industry, the production equipment of explosives is very critical.
[0003] In the production of explosives, existing combiners usually operate in batches. In this batch operation mode, the raw materials are first put into the reactor at one time, and then discharged uniformly after a certain period of reaction. However, this method has many problems. First, since the entire reaction process is a one-time feeding and one-time discharge, the size of the generated explosive particles is uneven. This is because during the reaction process, the reactant concentration, temperature and other conditions at different positions and time periods may be different, which affects the growth rate of the crystal and the final particle size.
[0004] Secondly, the stacking density of the explosive produced is unstable. Due to the uneven particle size, the gaps and density during stacking are also inconsistent, which not only brings difficulties to the subsequent process, but also the density of the agent is not kept within a fixed or predictable range when it is stacked, but shows large fluctuations and changes. Specifically, each time the stacking of the agent is measured or processed, the density value obtained may vary greatly, and it is impossible to form a stable pattern or expectation. This instability makes it difficult for the subsequent process to accurately grasp the dosage and performance of the agent, increases the difficulty and uncertainty of the operation, and also requires the removal of large and small particles before use. This screening process increases the complexity of the process, reduces production efficiency, and also affects the yield of the product, resulting in a significant increase in production costs.
[0005] In addition, in order to promote uniform reaction, blowing and stirring are usually adopted. At present, a vent pipe is inserted at a certain position of the bottom or side wall of the reactor, and gas is blown out from the pipe to form an upward airflow to stir the material, or multiple vent pipes are set at different positions of the bottom or side wall of the reactor. These vent pipes are evenly or specifically distributed to blow and stir the material more comprehensively. An annular vent pipe is set around the inside of the reactor, and gas is blown out from multiple small holes or gaps on the annular pipe to form a relatively uniform stirring airflow. However, this method also has problems in practical applications. Despite the upward airflow or multiple air outlets, there may still be poor stirring effect in local areas, resulting in uneven material mixing, affecting the consistency of the reaction and product quality. It is difficult to accurately control the ventilation volume and gas pressure, because precise control is mainly to achieve a more ideal stirring effect, ensure that the materials can be fully and evenly mixed, thereby promoting uniform reaction, improving the consistency of the reaction and product quality. Different reaction stages and material compositions may have large changes in the demand for ventilation volume, which is difficult to accurately predict and respond in real time, and cannot be flexibly adjusted according to the real-time needs of the reaction.
[0006] In addition, when gas is continuously passed through the bottom of the reactor to generate bubbles, the use of existing liquid level sensors is prone to missed reports and false reports. This is because the presence of bubbles interferes with the normal detection of the liquid level sensor, making it unable to accurately reflect the actual situation of the liquid level. Summary of the invention
[0007] In view of the deficiencies in the prior art, the technical problem solved by the present invention is to provide a continuous chemical combination reactor, which can ensure that the concentration of materials and reaction conditions remain stable during the reaction process through continuous feeding and discharging. Through precise feeding control and real-time reaction monitoring, the generated detonating agent particles are uniform in size and the agent stacking density is stable. There is no need for additional particle screening steps, which improves the yield and reduces production costs.
[0008] In order to solve the above problems, the technical solution adopted by the present invention is: a continuous chemical reaction reactor, comprising a reactor, wherein the side wall of the reactor is hollow, and a mechanical stirring device is fixedly arranged at the upper end surface of the reactor, and one end of the mechanical stirring device extends into the reactor; a raw material solution pipe and a water inlet pipe are arranged on one side of the mechanical stirring device; a sensor is arranged on one side of the stirring device, and one end of the sensor extends into the reactor; the side wall of the reactor is provided with cold and hot water inlets and cold and hot water return ports connected to the reactor interlayer circulation; an air pipe is arranged at the bottom of the reactor, and the air pipe is inserted into the bottom of the reactor; a discharge port is arranged at the lower end of the reactor, and the discharge port is connected to a plurality of suction tanks arranged at the lower end of the discharge port, and a valve is arranged between the discharge port and the suction tank; the mechanical stirring device extends into the reactor.
[0009] The beneficial effects of this program are:
[0010] 1. The side wall of the reactor is in a hollow interlayer configuration. The side wall of the reactor is provided with a cold and hot water inlet and a cold and hot water return port for circulation communication. When the reaction occurs in the reactor, the reaction temperature can be controlled by the temperature of the cold and hot water inlet and the cold and hot water return port circulation. The conditions in the reaction process are kept stable, which is beneficial to improving product quality and consistency. The mechanical stirring device arranged at the upper end of the reactor and the air pipe obliquely inserted at the bottom are combined to achieve full stirring and mixing of the reaction materials at different positions and levels. The mechanical stirring device stirs at the top, and the air stirring forms stirring forces at different levels at the bottom. This multi-level stirring method allows the materials to be stirred at the bottom. Different heights and positions in the reactor can be fully stirred and mixed, avoiding uneven mixing of materials in some parts, so that the reactants can contact and react more evenly, which plays a screening role and is conducive to the generation of explosive particles of uniform size, improving reaction efficiency and uniformity. The mechanical stirring device extends into the reactor and can effectively stir the materials in the upper and middle parts. Its stirring action can break the laminar state of the materials, so that the materials are fully mixed in the horizontal direction, promote uniform contact and reaction between the reactants, and better promote material mixing, so that the generated explosive particles are uniform in size, the reagent stacking density is stable, and the product quality is improved.
[0011] 2. Through continuous feeding and discharging, the continuous feeding method can continuously replenish fresh reactants so that the concentration of reactants in the reactor is always maintained at a relatively stable level. In this way, the reaction rate can remain relatively stable, and reaction conditions such as temperature and pressure are easier to control within the ideal range, ensuring the stability of the material concentration. Continuous discharging can discharge the product in time to avoid excessive accumulation of the product in the reactor, thereby preventing it from inhibiting the reaction or interfering with the reaction conditions. Since the material concentration can be stably controlled, the quality and performance of each batch of products will be more uniform and consistent, reducing the difference between batches and facilitating large-scale continuous production.
[0012] 3. Mechanical stirring is arranged at the upper end, and the mechanical stirring device extends to one-third of the position in the reactor. The air pipe is obliquely inserted at the conical part of the reactor for air stirring. The mechanical stirring acts on the upper part, and the air stirring is obliquely intervened from the bottom of the cone. The two can synergistically change the flow path of the material, making its flow in the reactor more complex and comprehensive, reducing the flow dead angle, and promoting the full mixing of the material. Air stirring at the bottom of the cone can effectively prevent the deposition and agglomeration of the material at this position, especially for some materials that are easy to precipitate. The oblique insertion of the air pipe makes the airflow enter the reactor at a certain angle instead of vertically upward. This oblique airflow direction can cover a wider area, increase the contact area and range of action with the material, and thus produce a wider range of agitation. Compared with vertical insertion, the oblique insertion of the air pipe can effectively prevent the deposition and agglomeration of the material at this position. The inclined airflow has a more directional push and disturbance on the material, and can more powerfully promote the movement and mixing of the material. The inclined airflow can drive the bottom material to flow along the inclined direction, forming better circulation and exchange with the middle and upper materials, thereby achieving more powerful stirring and more complete mixing. Extending to one-third of the position can reduce the violent splashing of the material during the initial stirring. If it is extended to the bottom, strong stirring may cause a large amount of material to be thrown up, resulting in material loss and unstable reaction environment. At the same time, if it is extended to only one-third of the position, the energy required to drive the mechanical stirring device is relatively small, while extending to the bottom requires greater power to drive, which increases energy consumption. In addition, the stirring device does not extend to the bottom, leaving more space for observing the bottom reaction and performing related operations, which helps to more intuitively understand the condition at the bottom of the reactor.
[0013] Furthermore, the air pipe is arranged at a position near the conical mouth end face at the bottom of the reactor. The position near the conical mouth end face can make the introduced gas more evenly distributed at the bottom of the reactor, reduce the unevenness of gas distribution, thereby better promoting the mixing and reaction of materials, and help prevent the reaction materials from depositing at the bottom of the cone. The stirring effect of the gas can make the materials easier to stir and avoid material accumulation and agglomeration.
[0014] Furthermore, a temperature sensor is provided on the side wall of the reactor, and the temperature sensor is arranged at the bottom of the reactor in a conical structure. Due to the conical bottom, the material is more likely to accumulate and concentrate in this area, which increases the chances of collision and contact between reactant molecules. In addition, the conical structure may cause the pressure at the bottom to be relatively high, which will affect the interaction and reaction activity between molecules, making the reaction more intense. It is also a part where the temperature changes more significantly. Setting a temperature sensor here can more accurately obtain the temperature information of the key position and timely reflect the actual temperature conditions of the reaction.
[0015] Furthermore, the cold and hot water return ports are arranged near the upper end of the reactor, the cold and hot water inlets are arranged near the bottom end of the reactor, and the cold and hot water inlets and the cold and hot water return ports are arranged on opposite side walls of the reactor and are circularly connected. The upper and lower and opposite side arrangements form a larger temperature gradient, which promotes sufficient convection and heat exchange of cold and hot water in the reactor, making heat exchange more uniform and efficient.
[0016] Furthermore, a pressure regulating valve and a flow rate detection sensor are provided on the air pipe and are connected to the air pipe. The pressure regulating valve can accurately adjust the pressure of the gas according to the requirements of the reaction, thereby controlling the amount of gas introduced into the reactor and ensuring that the reaction is carried out in a suitable gas environment. The flow rate detection sensor can monitor the flow rate of the gas in real time, and the operator can understand the ventilation conditions in time to make corresponding adjustments. At the same time, it avoids damage to the reactor due to excessively fast gas flow rate or excessively high pressure, or poor reaction effect due to excessively slow flow rate or too low pressure, thereby ensuring the safety and stability of the reaction process.
[0017] Furthermore, two pneumatic tube clamp valves are arranged at the lower end of the discharge port, and a sedimentation pipeline is arranged between the pneumatic tube clamp valves to realize the single-opening aggregation function. When aggregating, the upper valve is opened and the lower valve is closed, and the particles generated in the reactor fall into the middle of the two tube clamp valves; the single-opening discharge function, when discharging, the upper valve is closed and the lower valve is opened, and the material is discharged into the filtration tank. The single-opening discharge time interval can be controlled and set, and the double-opening quick emptying function, the upper and lower valves are opened at the same time to discharge the material in the reactor.
[0018] Furthermore, the air blowing liquid level sensor extends into the interior of the reactor and is located between the stirring device and the air stirring device, and is arranged close to the side wall of the reactor, between the stirring device and the air stirring device, which can reduce the direct interference of the two devices on the liquid level measurement when they are in operation and improve the accuracy of the liquid level measurement.
[0019] Furthermore, the water inlet pipe is a pure water inlet pipe, which prevents impurities in the water from entering the reaction system, thereby ensuring the purity and quality of the reaction and reducing the contamination and impact of impurities on the reaction products. The components in pure water are stable, and its physical and chemical properties are relatively fixed, which helps to more accurately control the reaction conditions and improve the repeatability and stability of the reaction.
[0020] Furthermore, when starting the operation, the mechanical stirring device is turned on at the same time as the gas stirring. The gas stirring and mechanical stirring act simultaneously, which can quickly form a diversified stirring flow field. The two complement each other, making the stirring more sufficient and uniform, greatly improving the stirring efficiency and effect, and being able to quickly mix the materials evenly in a short time, shortening the time required to reach a uniform state, speeding up the production process, and working together to more effectively maintain the stability of the stirring system, reduce local concentration differences and temperature differences, and reduce the possibility of adverse phenomena such as stratification, precipitation or local overheating. BRIEF DESCRIPTION OF THE DRAWINGS
[0021] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION
[0022] The reference numerals in the drawings of the specification include: reactor 1, cold and hot water return port 2, cold and hot water inlet 3, mechanical stirring device 4, raw material solution pipe 5, sensor 6, water inlet pipe 7, temperature sensor 8, tapered portion 9, air pipe 10, discharge port 11, valve 12, suction filter tank 13, sedimentation pipeline 14
[0023] Embodiment 1 is basically as attached Figure 1 As shown: a continuous chemical reactor 1, including a reactor 1, the side wall of the reactor 1 is arranged in a hollow structure, a mechanical stirring device 4 is fixedly arranged at the upper port position of the reactor 1, one end of the mechanical stirring device 4 extends into the reactor 1 to stir the reactor 1, a raw material solution pipe 5 and a water inlet pipe 7 are arranged on one side of the mechanical stirring device 4, and the water inlet pipe 7 is a pure water inlet pipe 7, the raw material solution pipe 5 and the water inlet pipe 7 extend into the reactor 1, a sensor 6 is arranged on one side of the mechanical stirring device, the sensor 6 is a blowing liquid level sensor 6, one end of the blowing liquid level sensor 6 extends into the reactor 1 and is located between the stirring device 4 and the gas stirring 10, and is arranged close to the side wall of the reactor 1, between the mechanical stirring device 4 and the gas stirring 10, which can reduce the direct interference of the two devices on the liquid level measurement when they are in operation.
[0024] A hot and cold water return port 2 and a hot and cold water inlet 3 are arranged on the side wall of the reactor 1 near the upper end of the reactor 1. The hot and cold water inlet 3 is arranged near the bottom end of the reactor 1, and the hot and cold water inlet 3 and the hot and cold water return port 2 are arranged at the opposite side walls of the reactor 1 and are cyclically connected with the hollow interlayer of the side wall of the reactor 1. Cold water or hot water can be introduced according to the reaction situation of the reactor 1. The hot and cold water return port 2 and the hot and cold water inlet 3 are arranged up and down and on the opposite sides. Although the hot and cold water inlets are circulated, the positions where they enter the reactor 1 are different. When cold water enters from the water inlet at the bottom or one side, and hot water enters from the water inlet at the top or the other side, due to the difference in initial temperature, before the two meet and mix, an obvious temperature difference will be formed in the local area, thereby forming a temperature gradient, which promotes sufficient convection and heat exchange of cold and hot water in the reactor 1, and makes the heat exchange more uniform and efficient.
[0025] An air pipe 10 is inserted obliquely at the bottom end of the reactor 1. A pressure regulating valve and a flow rate detection sensor are arranged on the air pipe 10 and connected to the air pipe 10. The pressure regulating valve can accurately adjust the pressure of the gas according to the needs of the reaction, thereby controlling the amount of gas introduced into the reactor 1. By adjusting the pressure, the flow rate and flow rate of the gas can be changed, thereby controlling the amount of gas introduced into the reactor and ensuring that the reaction is carried out in a suitable gas environment. The flow rate detection sensor can monitor the flow rate of the gas in real time, and the operator can understand the ventilation conditions in time to make corresponding adjustments. At the same time, it is avoided that the reactor 1 is damaged due to excessively fast gas flow rate or excessively high pressure, or that the reaction effect is poor due to excessively slow flow rate or too low pressure, thereby ensuring the safety and stability of the reaction process.
[0026] The bubbles generated by the gas in the water are used to distinguish and select medicines of different weights or sizes. The finished medicines fall to the finished product area at the bottom of the tank due to their large weight. When a certain amount is accumulated, the valve is used to intermittently discharge the finished products. The small-mass particles are brought back to the upper reaction area by the bubbles and continue to grow with the raw materials added at the top under the action of the stirring paddle until they reach the corresponding weight and fall into the finished product area at the bottom of the reactor 1.
[0027] A discharge port 11 is provided at the bottom of the reactor 1, and the discharge port 11 is connected to a plurality of suction filtration tanks 13 provided at the lower end of the discharge port 11, and a valve 12 is provided between the suction filtration tank 13 and the discharge port 11, and the valve 12 is a start-up pipe clamp valve, and two valves 12 are provided at the lower end of the discharge port 11, and a deposition pipeline 14 is provided between the valves 12, and the two valves 12 provide dual control and interception, even if one valve 12 fails or intercepts the particles in the reaction, the other valve can still play a certain role and reduce the risk of leakage, and the deposition pipeline 14 can alleviate the impact of the material when discharging to a certain extent, reduce the wear of the valve 12 and the pipeline, and extend the service life of the equipment, and because the sealing components of the valve 12 are all rubber, etc. Soft material, no metal material, avoids metal friction or hard contact of general valves, and increases safety. The two valves are separated by a certain distance, and a certain amount of finished medicine can be stored in the middle. When the upper valve is opened and the bottom valve is closed, the medicine at the bottom of the reactor 1 naturally flows into the pipeline between the two pipe clamp valves, so as to achieve the function of temporarily storing the finished medicine. Since the rate of generated finished medicine is relatively stable, the single discharge amount can be adjusted by changing the frequency of valve switching to achieve the function of quantitative discharge. When the upper valve is closed and the bottom valve is opened, the medicine and the liquid inside the tube flow into the bottom suction tank 13 together, so as to achieve the function of discharging. When the reaction is completed, the upper and lower valves are opened at the same time, and the liquid quickly flows into the bottom suction tank 13, so as to achieve the function of rapid liquid discharge.
[0028] In actual use, the continuous chemical reaction vessel 1 of the present invention is operated according to the following steps:
[0029] First, before starting the reaction, ensure that the reactor 1, each feed pipe, discharge pipe, stirring device, sensor, valve and other equipment are in normal working condition, check the hollow layer of the side wall of the reactor 1, and confirm that the circulation system of the cold and hot media is normal and there is no leakage.
[0030] While stirring the tracheal ventilation, turn on the mechanical stirring device. The air stirring and mechanical stirring work at the same time, which can quickly form a diverse stirring flow field. The two complement each other, making the stirring more sufficient and uniform, greatly improving the stirring efficiency and effect, and being able to quickly mix the materials evenly in a short time, shortening the time required to reach a uniform state, and speeding up the production process. The combined effect can more effectively maintain the stability of the stirring system, reduce local concentration differences and temperature differences, and reduce the possibility of adverse phenomena such as stratification, precipitation or local overheating. In addition, start the mechanical stirring device and air stirring before adding materials. If you add materials first and then stir, irregular crystal particles are likely to be generated.
[0031] When the equipment is in use, the mechanical stirring device 4 extends to one-third of the position inside the reactor 1, which can penetrate into the material to perform more intense and comprehensive stirring, further improving the mixing degree and reaction rate of the material.
[0032] During the reaction process, continuous feeding is carried out through the raw material solution pipe 5 and the water inlet pipe 7, wherein the water inlet pipe 7 adopts a pure water inlet pipe 7 to ensure that the water entering the reaction system is pure and free of impurities, reduce interference with the reaction, and accurately control the reaction conditions. The feeding speed and amount are adjusted according to the real-time reaction monitoring data to maintain the stable concentration of the reactants in the reactor 1.
[0033] The gas is continuously introduced through the gas pipe 10 which is obliquely inserted into the bottom of the reactor 1. The gas pipe 10 is arranged at the bottom of the reactor 1 near the end face of the conical mouth, so that the gas can be more evenly distributed at the bottom, thereby promoting the mixing and reaction of the materials and preventing the deposition of the materials. The pressure regulating valve and flow rate detection sensor arranged on the gas pipe monitor and adjust the pressure and flow rate of the gas in real time, and accurately control the ventilation volume according to the real-time situation of the reaction to avoid the particle size not meeting the requirements due to excessive or insufficient gas volume.
[0034] The temperature sensor 8 arranged on the side wall of the reactor 1 monitors the reaction temperature in real time. In particular, the temperature sensor 8 arranged at the bottom of the conical structure can accurately reflect the temperature changes in this violent reaction area and provide key data for temperature control. Through the hot and cold water inlets 3 and the hot and cold water return ports 2 on the side wall, the hot and cold media are circulated according to the data of the temperature sensor 8 to accurately control the reaction temperature.
[0035] The air blowing liquid level sensor 6 monitors the liquid level in the reactor 1 in real time. It extends to the inside of the reactor 1 between the stirring device and the air stirring device 10 and close to the side wall. It can accurately measure the liquid level and avoid interference from the mechanical stirring device 4. At the same time, it can effectively eliminate the influence of bottom bubbles, accurately feedback the liquid level information, and prevent underreporting and false alarms.
[0036] After the reaction is completed, the product is discharged through the discharge port 11 at the lower end of the reactor 1. The two pneumatic pipe clamp valves 12 set in the gaps at the lower end of the discharge port 11 control the discharge speed and flow rate. The double valves ensure the sealing and controllability of the discharge. The setting of the deposition pipeline alleviates the impact during discharge and reduces the wear of the valve and pipeline. The product enters the multiple suction tanks 13 set at the lower end of the discharge port 11 for subsequent treatment.
[0037] Such a specific implementation method can give full play to the advantages of the continuous chemical combination reactor 1 of the present invention, ensure the stability, efficiency and controllability of the reaction process, improve product quality and production efficiency, and reduce production costs and safety risks.

For those skilled in the art, various changes, modifications, substitutions and deformations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
