Description

[0002] As the name implies, the ammonium perchlorate crystallization device is a device used to assist the crystallization of ammonium perchlorate from ammonium perchlorate solution, and the digital optimization control system is a digital visualization and optimization control system formed to match the crystallization process of the ammonium perchlorate crystallization device.

[0003] After searching, the invention patent with Chinese patent publication number CN118767469A and the invention patent with publication number CN118416524B respectively disclose a crystallization device for producing ammonium perchlorate and an ammonium perchlorate cooling crystallization device and method with adjustable particle size. The former is roughly described as comprising a crystallization tank, a ring plate is rotatably connected to the lower end of the outer edge of the crystallization tank, a spiral tube is spirally arranged on the outer side of the crystallization tank above the ring plate, an expansion water stop strip is fixed in the spiral gap of the spiral tube, an outlet pipe and an inlet pipe connected to the spiral pipe are respectively fixed at the upper end and the lower end of the spiral tube, a first retaining ring is fixed on the vertical part of the inlet pipe, a second retaining ring is fixed on the vertical part of the outlet pipe, an outer shell is sleeved on the outer side of the crystallization tank, an arc-shaped first limiting hole is opened on the ring plate, and a top plate of the shell is provided with a first retaining hole. An arc-shaped second limiting hole is provided. When in use, after cooling water flows through the spiral tube, condensed water will appear on the outer edge of the spiral tube. After the condensed water contacts the expansion water stop strip, the expansion water stop strip can expand, thereby increasing the pitch of the spiral tube, and the spiral tube will be further close to the outer edge of the crystallization tank, thereby improving the heat transfer effect between the spiral tube and the crystallization tank. The latter can be roughly described as comprising a crystallization tank body, a cooling mechanism and a stirring mechanism, the stirring mechanism comprising a driving source, a stirring shaft, stirring blades and a cleaning component, the driving end of the driving source is connected to the top end of the stirring shaft, the stirring shaft is located in the crystallization tank body, and the stirring blades are installed at the bottom end of the stirring shaft. When in use, the movable hidden cleaning component arranged on the stirring mechanism can freely adjust the scraping time of the scraping component to realize intermittent scraping of the scraping component.

[0004] Although the above-mentioned prior art solutions can realize the crystallization operation of ammonium perchlorate, most of the prior art solutions including the above-mentioned two technical solutions adopt the form of circulating cooling water around the ammonium perchlorate solution to reduce the temperature of the ammonium perchlorate solution. Since the supersaturation of the ammonium perchlorate solution increases during the cooling process, the precipitation of ammonium perchlorate crystals is realized. Such an extraction method requires a large amount of ammonium perchlorate solution to be placed in the area surrounded by the circulating cooling water, and the cooling of the circulating cooling water takes a long time. With the gradual crystallization of the ammonium perchlorate in the ammonium perchlorate solution, the ammonium perchlorate content in the ammonium perchlorate solution will decrease, so the stability and consistency of the ammonium perchlorate crystallization extraction process are also poor.

The auxiliary conduction cooling of the liquid promotes the crystallization of ammonium perchlorate. The external tube 26 is fixedly connected with an insertion tube rack 27, which is fixedly connected to the cooling water tank 2. An insertion tube rack 27 is slidably connected with an insertion cylinder 28. A threaded rod 29 is threadedly connected to the insertion tube rack 28. The threaded rod 29 is rotatably connected to the insertion tube rack 27. The insertion cylinder 28 is connected with the external tube 26 to adjust the pumping height of the cooling water in the cooling water tank 2. It can cooperate with the distribution area of ​​the first annular tube 3 and the second annular tube 4, relative to the local area with faster temperature rise. The cooling water is extracted in a targeted and preferential manner, and if a control motor is installed on the insertion tube rack 27 to realize the rotation control of the threaded rod 29, the real-time height drive of the insertion tube 28 can also be realized, so as to achieve real-time adjustment of the insertion depth of the insertion tube 28 relative to the cooling water tank 2. A contact sealing arc plate 30 is fixedly connected to the bottom end of the insertion tube rack 27, and a contact sealing is set between the contact sealing arc plate 30 and the insertion tube 28.

[0038] It should be further explained that the multiple crystallization mechanisms each include a first annular tube 3 and a second annular tube 4, the cooling water tank 2 is provided with a plurality of first introduction ports 5, a plurality of second introduction ports 6, a plurality of first outlet ports 7 and a plurality of second outlet ports 8, the plurality of first annular tubes 3 are respectively introduced into the cooling water tank 2 through the plurality of first introduction ports 5, the plurality of first annular tubes 3 are respectively led out of the cooling water tank 2 through the plurality of first outlet ports 7, the plurality of second annular tubes 4 are respectively introduced into the cooling water tank 2 through the plurality of second introduction ports 6, the plurality of second annular tubes 4 are respectively led out of the cooling water tank 2 through the plurality of second outlet ports 8, and the first The first annular tube 3 and the second annular tube 4 are both provided with a liquid discharge port 9, a crystal discharge port 10 and a liquid addition port 11. Through the design of multiple crystallization mechanisms, a circulation channel for the ammonium perchlorate solution to pass through the cooling mechanism is formed, which facilitates the reduction of the temperature of the ammonium perchlorate solution. Since the cross-section of the first annular tube 3 and the second annular tube 4 is smaller than the cross-section of the cooling water tank 2, the temperature reduction efficiency of the ammonium perchlorate solution is higher. The liquid discharge port 9 is fixedly connected with a liquid discharge fast pipe 32, the crystal discharge port 10 is fixedly connected with a crystal discharge fast pipe 33, and the liquid addition port 11 is fixedly connected with a liquid addition fast pipe 34. , it is convenient to form an auxiliary connection operation with the corresponding pipeline outside, a first partition component is installed in each of the multiple first annular tubes 3, and a second partition component is installed in each of the multiple second annular tubes 4. The multiple first partition components and the multiple second partition components all include a track ring 12, and the multiple track rings 12 are respectively arranged in the multiple first annular tubes 3 and the multiple second annular tubes 4. Multiple piston members 13 are fixedly connected to the multiple track rings 12. The multiple piston members 13 located in the first annular tube 3 are all arranged to be contact-sealed with the first annular tube 3 in which they are located, and the multiple piston members 13 located in the second annular tube 4 are all arranged to be contact-sealed with the second annular tube 4 in which they are located. Through the design of the first partition component, the first annular tube 3 is divided into a plurality of relatively independent first crystallization chambers, and through the design of the second partition component, the second annular tube 4 is divided into a plurality of relatively independent second crystallization chambers, so as to realize the auxiliary driving of the ammonium perchlorate solution in the first annular tube 3 and the ammonium perchlorate solution in the second annular tube 4, and also facilitate the auxiliary separation of the crystals after crystallization of the ammonium perchlorate solution in the first crystallization chamber and the residual solution in the second crystallization chamber.

[0039] It should be further explained that a plurality of circulating drive structures are installed on the basic frame 1, and the plurality of circulating drive structures are respectively used to drive the plurality of first partition components, and the plurality of circulating drive structures are also respectively used to drive the plurality of second partition components, and the plurality of circulating drive structures all include an external fixed frame 14, and the plurality of external fixed frames 14 are fixedly connected to the basic frame 1, and the plurality of external fixed frames 14 are rotatably connected with rotating shafts 15, and the plurality of rotating shafts 15 are fixedly connected with driving wheel frames 16, and the plurality of driving wheel frames 16 are fixedly connected with driving bushings 17, and the plurality of driving bushings 17 are fixedly connected with a plurality of electromagnets, and the plurality of electromagnets are equipped with magnetic attraction rings 18, and the plurality of magnetic attraction rings 18 are respectively fixedly connected to the plurality of piston members 13, and the plurality of external fixed frames 14 are respectively installed with servo motors 19, and the plurality of servo motors 19 are respectively used for the rotational drive of the plurality of rotating shafts 15, and the design of the circulating drive structure can realize the motion drive of the first partition components and the motion drive of the second partition components, thereby realizing the sequential movement of the plurality of first crystallization cavities, and also realizing the plurality of second The sequential movement of the crystallization chamber achieves the realization and continuity of the preparation of ammonium perchlorate. Multiple driving liner frames 17 are provided with multiple circumferential grooves, and multiple circumferential grooves are slidably connected with mounting cylinders 20. Multiple circumferential grooves are fixedly connected with multiple ejection springs, and multiple ejection springs are matched with multiple mounting cylinders 20 respectively. Since the driving wheel frame 16 is provided with a raised structure, the raised structure cooperates with the gap between the corresponding first annular tube 3 and the second annular tube 4 to form a partial insertion. Therefore, when the driving liner frame 17 is inserted into the driving wheel frame 16, The ejection spring can push the mounting tube 20 relative to the driving bushing 17, so that the insertion tube 28 enters the area within the raised structure of the driving wheel frame 16, thereby reducing the relative distance between the relatively acting electromagnet and the magnetic attraction ring 18, thereby ensuring the magnetic attraction effect between the magnetic attraction ring 18 and the electromagnet. The multiple electromagnets all include a conductor fixing column 21, and the multiple conductor fixing columns 21 are respectively fixedly connected in the multiple mounting tubes 20. The multiple conductor fixing columns 21 are all wound with spiral wires 22, which demonstrates and displays the specific structure of the electromagnet.

[0040] The digital optimization control system of the ammonium perchlorate crystallization device includes an external computer 38, which is installed on the cooling water tank 2. The external computer 38 is electrically connected to an inlet water temperature sensor, a return water temperature sensor and multiple image cameras. The inlet water temperature sensor is installed on the inner bottom wall of the cooling water tank 2, and the return water temperature sensor is installed at the bottom end of the insertion tube 28. The multiple image cameras are respectively installed in multiple crystal row fast pipes 33. Monitoring software is installed in the external computer 38. The monitoring software is used to read and process the information collected by the inlet water temperature sensor, the return water temperature sensor and the multiple image cameras. The circulating pump 23, the cooling compressor 24, the spiral wire 22 and the multiple servo motors 19 are all controlled by the monitoring software.

[0041] The spiral conductor 22 in this embodiment is equipped with a current controller, and the signal of the current controller is connected to the external computer 38 and is monitored and controlled. The current controller, servo motor 19, external computer 38, water inlet temperature sensor, return water temperature sensor, image camera, circulation pump 23 and cooling compressor 24 are all conventional equipment purchased on the market and known to technicians in this field. In the present invention, we only use them and do not improve their structure and function. For technicians in this field, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and they will not be described in detail here.

[0042] In summary, the working principle of the ammonium perchlorate crystallization device and the digital optimization control system is as follows: before operation, the ammonium perchlorate crystallization device and the digital optimization control system are first moved to the desired location, and the ammonium perchlorate crystallization device and the digital optimization control system are inspected and debugged. After the debugging is completed, the liquid discharge quick pipe 32 is relatively connected to the external wastewater recovery temporary storage device, the crystal discharge quick pipe 33 is relatively connected to the external ammonium perchlorate crystal temporary storage device, and the liquid addition quick pipe 34 is connected to the external ammonium perchlorate feeding device. Then, the circulation pump 23 and the cooling compressor 24 are started first, and the circulation pump 23 is operated. The cooling water in the cooling water tank 2 is extracted through the insert tube 28 and the extracted cooling water is sent back into the cooling water tank 2 through the pumping pipe 25. During the flow of the cooling water, auxiliary cooling is formed through the cooling compressor 24, so as to maintain the temperature of the cooling water in the cooling water tank 2. The monitoring software in the external computer 38 collects the temperature of the cooling water at the bottom of the cooling water tank 2 and the water temperature of the cooling water at the bottom of the insert tube 28 in real time through the inlet water temperature sensor and the return water temperature sensor, respectively, and sets the temperature difference range value according to the actual situation. When the actual collected temperature difference exceeds the set temperature difference range value, the circulation pump 23 and the cooling compressor 24 start to run synchronously. On the contrary, if the actually collected temperature difference is less than the set temperature difference range value, the circulation pump 23 and the cooling compressor 24 will stop running synchronously. After the actually collected temperature difference enters the set temperature difference range value, the servo motor 19 will be started. The servo motor 19 will work by rotating the shaft 15 to realize the rotation of the driving wheel frame 16 installed on the rotating shaft 15. The driving wheel frame 16 rotates to drive the driving liner 17 therein to form a synchronous rotation drive. The driving liner 17 rotates to drive the multiple electromagnets therein to form movement, and the spiral wire 22 in the electromagnet that controls the movement close to the matching first annular tube 3 and the second annular tube 4 is energized, so that the electromagnet generates an electromagnetic field, and the electromagnetic The field generated will form a magnetic attraction relative to the nearby magnetic attraction ring 18, so that the magnetic attraction ring 18 forms a follow-up movement along with the movement of the electromagnet. Along with the synchronous movement of multiple electromagnets, multiple electromagnets rotating close to the first annular tube 3 and the second annular tube 4 are controlled to be energized in sequence to form the traction drive of the magnetic attraction ring 18, and multiple electromagnets rotating away from the first annular tube 3 and the second annular tube 4 are controlled to be de-energized in sequence to reduce the reverse traction effect of the distant electromagnet on the magnetic attraction ring 18, thereby forming the synchronous drive of multiple piston members 13 in the first annular tube 3, and also realizing the synchronous drive of multiple piston members 13 in the second annular tube 4.

[0043] Further, along with the synchronous driving of the piston member 13, the external ammonium perchlorate solution feeding device adds the ammonium perchlorate solution to the first annular tube 3 and the second annular tube 4 through the liquid adding quick pipe 34, and the ammonium perchlorate solution entering the first annular tube 3 will enter the multiple first crystallization chambers in sequence along with the movement of the multiple piston members 13 in the first annular tube 3, and along with the relative position change of the multiple first crystallization chambers in the first annular tube 3, they are first cooled by the cooling water in the cooling water tank 2, so that the temperature of the ammonium perchlorate solution is reduced to promote the crystallization of ammonium perchlorate in the ammonium perchlorate solution, and then the multiple first crystallization chambers are sequentially moved out of the cooling area of ​​the cooling water tank 2. After the multiple first crystallization chambers are moved out of the cooling water tank 2, the non-crystallized solution will be first discharged through the drain port 9, and then the crystallized ammonium perchlorate will be discharged through the crystal discharge port 10, completing a crystallization cycle. Since the pores of the drain port 9 are small, the crystallized ammonium perchlorate can be blocked, and then the external ammonium perchlorate solution is added again through the liquid adding quick pipe 34 to reach the next crystallization cycle, and similarly enter the second annular tube 4 The ammonium perchlorate solution in the second annular tube 4 will enter the multiple second crystallization chambers in sequence along with the movement of the multiple piston members 13 in the second annular tube 4, and successively form the cooling crystallization of the ammonium perchlorate solution, the discharge of the uncrystallized solution and the discharge of the crystallized ammonium perchlorate. Since the effective flow area of ​​the first annular tube 3 and the second annular tube 4 is small, the cooling water in the cooling water tank 2 has a sufficient heat exchange effect. At the same time, the monitoring software collects the image information of the image camera in real time, and collects the image of the state at the crystal discharge port 10 to achieve the detection of the ammonium perchlorate crystal discharge situation. According to the detection content, on the one hand, the temperature of the cooling water is controlled to achieve the control of the extreme temperature drop of the ammonium perchlorate solution. On the other hand, the servo motor 19 is controlled to drive the synchronous movement speed of multiple electromagnets to control the cooling time of the ammonium perchlorate solution through the cooling water tank 2, and finally the crystallization of the ammonium perchlorate solution is controlled. The monitoring software realizes the optimization control of the crystallization process of the ammonium perchlorate solution according to the collected information and forms a digital display of the corresponding indicators, thereby achieving the effect of digital optimization control, as shown in the attached Figure 1 The figure shows a distribution effect of a plurality of first annular tubes 3 and a plurality of second annular tubes 4 relative to the cooling water tank 2, as shown in the attached figure. Fig.13Another distribution effect of multiple first annular tubes 3 and multiple second annular tubes 4 relative to the cooling water tank 2, since the multiple first annular tubes 3 and the multiple second annular tubes 4 are relatively independent, when the ammonium perchlorate crystallization efficiency is required to be high, the multiple first annular tubes 3 and the multiple second annular tubes 4 can be simultaneously fed with ammonium perchlorate solution to form an ammonium perchlorate high-efficiency crystallization operation; when the ammonium perchlorate crystallization efficiency is required to be low, the ammonium perchlorate solution can be simultaneously fed into a single first annular tube 3 and a second annular tube 4 to form an ammonium perchlorate low-efficiency crystallization operation, the equipment is more flexible to use, and since the ammonium perchlorate solution contained in the first crystallization chamber and the second crystallization chamber is less than the ammonium perchlorate solution contained in the crystallization tank of the prior art, the time node limitation when stopping the ammonium perchlorate crystallization operation is small, and the effective utilization rate of the ammonium perchlorate solution is also high. In order to ensure the replenishment and addition of cooling water in the cooling water tank 2, an addition port is provided on the cooling water tank 2, and a dust cover is provided at the addition port, and the dust cover has a ventilation function.
