Description

Technical Field

[0001] This invention relates to the field of crystal particle preparation technology, and in particular to a method, apparatus, electronic device, and computer-readable storage medium for preparing crystal particles to achieve specific requirements. Background Technology

[0002] Existing crystallizers are trough-shaped containers with jackets on the walls or coils inside for heating or cooling the solution. The crystallization trough can be used as an evaporative crystallizer or a cooling crystallizer. To improve crystal production intensity, a stirrer can be added inside the trough. The crystallization trough can be used for continuous or intermittent operation. Intermittent operation produces larger crystals, but the crystals are prone to clustering, carrying mother liquor and affecting product purity. This type of crystallizer has a simple structure and low production intensity. It cannot solve the technical problem of uneven crystal slurry concentration in existing solutions. At the same time, it cannot ensure that the crystal particles are free of mother liquor impurities, and the drying rate is slow, making it prone to agglomeration. Summary of the Invention

[0005] A speed reducer is fixedly installed at the middle of the upper end of the crystallization tank. A servo motor is fixedly installed at the upper end of the speed reducer. The speed reducer and the servo motor are connected by a main shaft. A stirring shaft is fixedly installed at the lower end of the speed reducer. The stirring shaft extends through the funnel into the cooling zone. A stirring paddle is fixedly installed at the lower end of the stirring shaft. A uniform stirring mechanism is fixedly installed on the arc surface of the stirring shaft.

[0006] The inner wall of the crystallization tank is fixedly installed with two centrally symmetrical uniform flow distribution mechanisms inside the uniformly divided area.

[0007] Preferably, the crystallization tank has a cooling zone and a uniform distribution zone inside, the uniform distribution zone is located above the cooling zone, and an annular cooling pipe is fixedly installed on the inner wall of the crystallization tank inside the cooling zone.

[0008] Preferably, the two ends of the annular cooling pipe are connected to the jacket, a funnel is fixedly installed on the inner wall of the crystallization tank at a position between the cooling zone and the equalization zone, and a feed inlet and a manhole are fixedly installed on the upper surface of the crystallization tank, with the manhole located on one side of the feed inlet.

[0009] Preferably, the uniform stirring mechanism includes a fixed bushing, which is fixed to the stirring shaft. Two mirror-distributed connecting rods are fixedly installed on the arc surface of the fixed bushing. U-shaped connecting rods are fixedly installed on the surfaces of the two connecting rods, and a plurality of equidistant crystal separation holes are fixedly installed on the surfaces of the U-shaped connecting rods.

[0010] Preferably, the uniform flow distribution mechanism includes a fixed plate, a fixed support plate is fixedly installed on the upper surface of the fixed plate, the upper end of the fixed support plate is fixedly installed on the inner wall of the crystallization tank, one end of the fixed plate near the fixed support plate is fixed on the inner wall of the crystallization tank, and a buffer pad is fixedly installed on one side surface of the fixed support plate.

[0011] Preferably, a plurality of equidistant oscillating motors are fixedly installed between the fixed plate and the buffer pad, and a plurality of springs corresponding to the oscillating motors are fixedly installed on the upper surface of the buffer pad.

[0012] Preferably, a buffer telescopic rod is fixedly installed on the upper surface of the buffer pad near one end, a uniform flow distribution plate is fixedly installed on the upper end of the buffer telescopic rod, the upper ends of several springs are fixed to the bottom of the uniform flow distribution plate, the stirring shaft passes through the uniform flow distribution plate, and a filter screen is fixedly installed on the upper surface of the uniform flow distribution plate.

[0013] A method for preparing crystal particles to achieve specific requirements, characterized in that it includes:

[0014] Add the crystal slurry solution to the concentration vessel and heat and concentrate it at a heating rate of 0.5 to 2 °C / min until the concentration of the crystal slurry solution reaches 55 to 65 Baume degrees to obtain the first solution;

[0015] The first solution is fed into the uniform distribution zone of the crystallization tank through the feed inlet. The uniform distribution mechanism is activated. The buffer pad on the fixed plate causes the spring between the moving uniform distribution plate and the buffer pad to vibrate, thereby driving the uniform distribution plate to vibrate. The buffer telescopic rod buffers the vibration intensity of the uniform distribution plate. The first solution flowing onto the uniform distribution plate is filtered by the filter screen and then flows evenly into the funnel, and then into the cooling zone to cool and crystallize.

[0016] The servo motor is started to drive the reducer to rotate, which in turn drives the stirring shaft to rotate, thereby causing the stirring paddle and the uniform stirring mechanism to rotate and stir the first solution evenly, so that the concentration of the first solution is uniform. The crystal separation hole on the U-shaped connecting rod rotates while stirring the first solution in a strip shape, which can crystallize quickly. At the same time, water is continuously injected into the jacket from the cooling water inlet. The water flows into the annular cooling pipe and finally exits from the cooling water outlet. The cooling rate is controlled at 15-25℃ / h until the cooling temperature drops to 60±2℃. Crystal seeds are added to the first solution, and the process of aging crystallization, centrifugation separation, and drying is carried out in sequence to obtain crystals. The particles of the first solution are discharged from the discharge port.

[0017] Preferably, during the cooling and crystallization process, the stirring is carried out at a stirring frequency of 5Hz and a stirring speed of 60-80 rpm. The filter screen is rigid and double-layered, with several layers of filter paper filling the space between the two layers of filter screen.

[0018] Preferably, the aging and crystallization temperature is 50-70℃, the time is 1-3 hours, the centrifuge rotation frequency during centrifugation is 40-50Hz, the rotation speed is 1200-1500 rpm / min, and the drying temperature is 55-65℃.

[0019] To address the above problems, the present invention also provides an electronic device, the electronic device comprising:

[0020] Memory, storing at least one instruction; and

[0021] The processor executes instructions stored in the memory to implement the crystal particle preparation apparatus and method described above for achieving specific requirements.

[0022] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the aforementioned apparatus and method for preparing crystal particles to achieve specific requirements.

[0023] Compared to the background technology, this invention, through its uniform flow distribution mechanism, enables the crystal slurry to flow evenly into the cooling zone, thus achieving uniform distribution. The uniform stirring mechanism ensures uniform concentration of the crystal slurry. The crystal slurry is fed into the uniform section of the crystallization tank from the inlet. Activating the uniform flow distribution mechanism causes the buffer plate on the fixed plate to vibrate the spring between the uniform flow distribution plate and the buffer plate, thereby causing the uniform flow distribution plate to vibrate. The buffer telescopic rod buffers the vibration intensity of the uniform flow distribution plate. The crystal slurry flowing onto the uniform flow distribution plate is filtered through a filter screen and then flows evenly into the funnel, before flowing into the cooling zone for cooling and crystallization. Activating the servo motor drives the reducer to rotate, which in turn drives the stirring shaft to rotate, causing the stirring paddle and the uniform stirring mechanism to rotate and stir the crystal slurry evenly, ensuring uniform concentration. The crystal separation holes on the U-shaped connecting rod, while rotating, cause the crystal slurry to be stirred in a strip shape, enabling rapid crystallization. Simultaneously, water is continuously injected from the cooling water inlet, flowing into the annular cooling pipe and finally exiting from the cooling water outlet, discharging the crystal slurry particles from the outlet. The preparation method of this invention obtains crystals by using a filter screen and sequentially performing aging crystallization, centrifugation, and drying. This ensures that the crystal particles are free of mother liquor impurities, and the drying rate is fast, preventing agglomeration. Therefore, the crystal particle preparation method, apparatus, electronic device, and computer-readable storage medium proposed in this invention, which are used to achieve specific requirements, can solve the technical problem of uneven crystal slurry concentration in existing solutions, while also ensuring that the crystal particles are free of mother liquor impurities, and that the drying rate is fast, preventing agglomeration.

[0033] Example 1:

[0034] Reference Figure 1 The diagram shown is a schematic representation of a crystal particle preparation apparatus for achieving specific requirements according to an embodiment of the present invention. In this embodiment, the crystal particle preparation apparatus for achieving specific requirements includes:

[0035] Please see Figure 1-3As shown, the present invention is a crystal particle preparation device for achieving specific requirements, including a crystallization tank 104, a jacket 103 fixedly installed on the outer surface of the crystallization tank 104, a discharge port 101 fixedly installed at the middle position of the lower end of the crystallization tank 104, the discharge port 101 being connected to the crystallization tank 104, the jacket 103 covering the bottom of the crystallization tank 104, the height of the jacket 103 being less than that of the crystallization tank 104, a cooling water inlet 102 fixedly installed at the bottom of the jacket 103 and communicating with the jacket 103, two mirror-distributed lugs 107 fixedly installed on the outer surface of the jacket 103, and a cooling water outlet 109 fixedly installed near the upper end of the outer surface of the jacket 103; the interior of the crystallization tank 104 is provided with a cooling zone 105 and a uniform distribution zone 1010, the uniform distribution zone 1010 being located above the cooling zone 105, and an annular cooling pipe 106 fixedly installed on the inner wall of the crystallization tank 104 inside the cooling zone 105.

[0036] The two ends of the annular cooling pipe 106 are connected to the jacket 103. A funnel 108 is fixedly installed on the inner wall of the crystallization tank 104 at the position between the cooling zone 105 and the equalization zone 1010. A feed inlet 1011 and a manhole 1012 are fixedly installed on the upper surface of the crystallization tank 104. The manhole 1012 is located on one side of the feed inlet 1011.

[0037] The jacket 103 wraps around the bottom of the crystallization tank 104, with the wrapping height not exceeding three-quarters of the height of the crystallization tank 104. The discharge port 101 is located at the middle of the bottom of the crystallization tank 104 and is connected to the crystallization tank 104. A movable sealing plate is provided on the discharge port 101 to prevent leakage of crystal slurry or particles. The two ends of the annular cooling pipe 106 are connected to the jacket 103. The annular cooling pipe 106 is spirally attached to the inner wall of the crystallization tank 104 and is located inside the cooling zone 105. Together with the jacket 103, it can improve the crystallization efficiency of the crystal slurry.

[0038] It should be explained that, in this embodiment of the invention, the crystal slurry is fed from the feed inlet 1011 into the uniform section 1010 of the crystallization tank 104, flows evenly into the funnel 108, and then flows into the cooling zone 105 for cooling and crystallization. At the same time, water is continuously injected into the jacket 103 from the cooling water inlet 102, and the water flows into the annular cooling pipe 106 and is finally discharged from the cooling water outlet 109, while the crystal slurry particles are discharged from the discharge outlet 101.

[0039] A speed reducer 205 is fixedly installed at the middle of the upper end of the crystallization tank 104. A servo motor 206 is fixedly installed at the upper end of the speed reducer 205. The speed reducer 205 and the servo motor 206 are connected by a main shaft. A stirring shaft 204 is fixedly installed at the lower end of the speed reducer 205. The stirring shaft 204 extends through the funnel 108 into the cooling zone 105. A stirring paddle 202 is fixedly installed at the lower end of the stirring shaft 204. A uniform stirring mechanism 201 is fixedly installed on the arc surface of the stirring shaft 204. The uniform stirring mechanism 201 includes a fixed bushing 207. The uniform stirring mechanism 201 is fixed to the stirring shaft 204 through the fixed bushing 207. Two mirror-distributed connecting rods 2010 are fixedly installed on the arc surface of the fixed bushing 207. A U-shaped connecting rod 208 is fixedly installed on the surface of each of the two connecting rods 2010. A number of equidistant crystal separation holes 209 are fixedly installed on the surface of the U-shaped connecting rod 208.

[0040] The reducer 205 is mounted on the crystallization tank 104 via a fixed base. The servo motor 206 is connected to the reducer 205 via a main shaft. The main shaft of the reducer 205 is connected to the stirring shaft 204. The stirring shaft 204 passes through the uniform distribution plate 308 and the funnel 108 and extends into the cooling zone 105. The stirring paddle 202 on the stirring shaft 204 and the uniform stirring mechanism 201 are located on the same plane. Moreover, the width of the uniform stirring mechanism 201 is smaller than the width of the stirring paddle 202. The stirring paddle 202 has a U-shaped structure. The uniform stirring mechanism 201 is located inside the U-shape. The connecting support rods 2010 on the uniform stirring mechanism 201 are mirror-distributed. The U-shaped connecting rods 208 on the connecting support rods 2010 are composed of multiple U-shaped structures. The diameter of the crystal separation hole 209 on the U-shaped connecting rod 208 ranges from 0.3 to 0.5 cm.

[0041] It should be explained that, in this embodiment of the invention, the servo motor 206 is started to drive the reducer 205 to rotate, which in turn drives the stirring shaft 204 to rotate, thereby driving the stirring paddle 202 and the uniform stirring mechanism 201 to rotate and stir the crystal slurry uniformly, so that the crystal slurry concentration is uniform. The crystal separation hole 209 on the U-shaped connecting rod 208 stirs the crystal slurry in a strip shape while rotating, which can quickly crystallize.

[0042] The inner wall of the crystallization tank 104 is located inside the uniform distribution zone 1010 and has two centrally symmetrical uniform flow distribution mechanisms 301 fixedly installed.

[0043] The uniform flow distribution mechanism 301 includes a fixed plate 302, a fixed support plate 305 is fixedly installed on the upper surface of the fixed plate 302, the upper end of the fixed support plate 305 is fixedly installed on the inner wall of the crystallization tank 104, one end of the fixed plate 302 near the fixed support plate 305 is fixed on the inner wall of the crystallization tank 104, and a buffer pad 304 is fixedly installed on one side surface of the fixed support plate 305.

[0044] A number of equidistant oscillating motors 303 are fixedly installed between the fixed plate 302 and the buffer pad 304, and a number of springs 306 corresponding to the oscillating motors 303 are fixedly installed on the upper surface of the buffer pad 304.

[0045] A buffer telescopic rod 307 is fixedly installed on the upper surface of the buffer pad 304 near one end. A uniform flow distribution plate 308 is fixedly installed on the upper end of the buffer telescopic rod 307. The upper ends of several springs 306 are fixed to the bottom of the uniform flow distribution plate 308. The stirring shaft 204 passes through the uniform flow distribution plate 308. A filter screen 309 is fixedly installed on the upper surface of the uniform flow distribution plate 308.

[0046] Two uniform flow distribution mechanisms 301 are centrally symmetrically distributed on the inner wall of the crystallization tank 104. Both uniform flow distribution mechanisms 301 are inside the uniform flow distribution section 1010. One uniform flow distribution mechanism 301 is located to the lower left of the other uniform flow distribution mechanism 301. Both uniform flow distribution mechanisms 301 are fixed to the crystallization tank 104 by a fixing plate 302 and a fixing support plate 305. The springs 306 between the buffer pad 304 and the uniform flow distribution plate 308 have different lengths and are adjusted according to the vertical height between the buffer pad 304 and the uniform flow distribution plate 308. The lower end of the uniform flow distribution plate 308 on the upper right extends above the uniform flow distribution plate 308 on the lower left, which allows the crystal slurry to fall onto the uniform flow distribution plate 308. The filter screen 309 on the uniform flow distribution plate 308 can filter impurities in the crystal slurry. Moreover, the uniform flow distribution plate 308 is provided with raised baffles on both sides to prevent the crystal slurry from spilling.

[0047] It should be explained that, in this embodiment of the invention, when the uniform flow distribution mechanism 301 is activated, the buffer pad 304 on the fixed plate 302 drives the spring 306 between the uniform flow distribution plate 308 and the buffer pad 304 to vibrate, thereby causing the uniform flow distribution plate 308 to vibrate. The buffer telescopic rod 307 buffers the vibration intensity of the uniform flow distribution plate 308. The crystal slurry flowing onto the uniform flow distribution plate 308 is filtered by the filter screen 309. The filter screen 309 is rigid and has two layers, with several layers of filter paper filling the space between the two layers of filter screen 309.

[0048] Compared to the background art, the present invention, through the uniform flow distribution mechanism 301, enables the crystal slurry to flow uniformly into the cooling zone 105, thereby achieving uniform distribution of the crystal slurry; the uniform stirring mechanism 201 ensures uniform concentration of the crystal slurry. The crystal slurry is fed from the inlet 1011 into the uniform distribution zone 1010 of the crystallization tank 104. When the uniform flow distribution mechanism 301 is activated, the buffer pad 304 on the fixed plate 302 causes the spring 306 between the uniform flow distribution plate 308 and the buffer pad 304 to vibrate, thereby causing the uniform flow distribution plate 308 to vibrate. The buffer telescopic rod 307 buffers the vibration intensity of the uniform flow distribution plate 308, allowing the slurry to flow to the uniform flow distribution plate 3010. The crystal slurry on plate 8 is filtered through filter screen 309 and then flows evenly into funnel 108, and then into cooling zone 105 for cooling and crystallization. Servo motor 206 is started to drive reducer 205 to rotate, which in turn drives stirring shaft 204 to rotate, thereby causing stirring paddle 202 and uniform stirring mechanism 201 to rotate and stir the crystal slurry evenly, ensuring uniform crystal slurry concentration. Crystal separation holes 209 on U-shaped connecting rod 208, while rotating, cause the crystal slurry to be stirred in a strip shape, enabling rapid crystallization. Simultaneously, water is continuously injected from cooling water inlet 102 into jacket 103, flowing into annular cooling pipe 106 and finally discharged from cooling water outlet 109, while the crystal slurry particles are discharged from outlet 101. The preparation method of this invention, through the filter screen 309 and sequential aging crystallization, centrifugal separation, and drying, obtains crystals that ensure the crystal particles do not contain mother liquor impurities, and has a fast drying rate, preventing clumping. Therefore, the present invention proposes a method, apparatus, electronic device and computer-readable storage medium for preparing crystal particles to achieve specific requirements, which can solve the technical problem of uneven concentration of crystal slurry in the existing solution, and at the same time can ensure that the crystal particles do not contain mother liquor impurities, and the drying rate is fast and not prone to agglomeration.

[0049] Example 2:

[0050] Reference Figure 4 As shown, a method for preparing crystal particles to achieve specific requirements is characterized by comprising:

[0051] Add the crystal slurry solution to the concentration vessel and heat and concentrate it at a heating rate of 0.5 to 2 °C / min until the concentration of the crystal slurry solution reaches 55 to 65 Baume degrees to obtain the first solution;

[0052] The first solution is fed into the uniform section 1010 of the crystallization tank 104 through the feed port 1011. The uniform flow distribution mechanism 301 is activated. The buffer pad 304 on the fixed plate 302 drives the spring 306 between the uniform flow distribution plate 308 and the buffer pad 304 to vibrate, thereby driving the uniform flow distribution plate 308 to vibrate. The buffer telescopic rod 307 buffers the vibration intensity of the uniform flow distribution plate 308. The first solution flowing onto the uniform flow distribution plate 308 is filtered by the filter screen 309 and then flows evenly into the funnel 108, and then into the cooling zone 105 to cool and crystallize.

[0053] The servo motor 206 is started to drive the reducer 205 to rotate, which in turn drives the stirring shaft 204 to rotate, thereby driving the stirring paddle 202 and the uniform stirring mechanism 201 to rotate and stir the first solution uniformly, so that the concentration of the first solution is uniform. The crystal separation hole 209 on the U-shaped connecting rod 208 stirs the first solution in a strip shape while rotating, which can crystallize quickly. At the same time, water is continuously injected into the jacket 103 from the cooling water inlet 102. The water flows into the annular cooling pipe 106 and finally exits from the cooling water outlet 109. The cooling rate is controlled at 15-25℃ / h until the cooling temperature drops to 60±2℃. Seed crystals are added to the first solution, and the aging crystallization, centrifugation separation and drying are carried out in sequence to obtain crystals. The particles of the first solution are discharged from the discharge port 101.

[0054] During the cooling and crystallization process, the stirring is carried out at a stirring frequency of 5Hz and a speed of 60-80rpm. The filter screen 309 is rigid and double-layered, with several layers of filter paper filling the space between the two layers of filter screen 309.

[0055] The aging and crystallization temperature is 50-70℃, the time is 1-3h, the centrifuge rotation frequency is 40-50Hz, the speed is 1200-1500rpm / min, and the drying temperature is 55-65℃.

[0070] The servo motor 206 is started to drive the reducer 205 to rotate, which in turn drives the stirring shaft 204 to rotate, thereby driving the stirring paddle 202 and the uniform stirring mechanism 201 to rotate and stir the first solution uniformly, so that the concentration of the first solution is uniform. The crystal separation hole 209 on the U-shaped connecting rod 208 stirs the first solution in a strip shape while rotating, which can crystallize quickly. At the same time, water is continuously injected into the jacket 103 from the cooling water inlet 102. The water flows into the annular cooling pipe 106 and finally exits from the cooling water outlet 109. The cooling rate is controlled at 15-25℃ / h until the cooling temperature drops to 60±2℃. Seed crystals are added to the first solution, and the aging crystallization, centrifugation separation and drying are carried out in sequence to obtain crystals. The particles of the first solution are discharged from the discharge port 101.
