DETAILED DESCRIPTION

[0021] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0022] like Figures 1 to 11 As shown, a continuous reaction crystallization drying device according to an embodiment of the present invention comprises a frame 10, on which a processing mechanism 20 is arranged; The processing mechanism 20 includes a processing cylinder 202 rotatably mounted on the frame 10 via a rotating shaft 201, the rotating shaft 201 is driven by a rotating assembly 40, the rotating assembly 40 includes a gear 41 fixedly mounted on the rotating shaft 201, a tooth plate 42 is fixedly mounted on the lifting plate 207, a plurality of mounting grooves 43 are provided on the tooth plate 42, a tooth block 44 is rotatably mounted in the mounting groove 43, one end of an elastic member 45 is fixedly mounted on the tooth block 44, and the other end of the elastic member 45 is fixedly connected to the inner wall of the mounting groove 43, a pair of heating chambers 2021 are provided in the processing cylinder 202, a heating wire 2022 is provided in the heating chamber 2021, a partition 203 is slidingly and sealingly mounted in the processing cylinder 202 to divide the space in the processing cylinder 202 into two working areas, and a positioning pin 20 is slidably mounted on the processing cylinder 202 4. One end of the positioning pin 204 passes through the processing cylinder 202 and is inserted into the partition 203 to abut against its inner wall. A central shaft 205 is rotatably installed on the partition 203. A pair of stirring members 206 for stirring the solution are arranged on the central shaft 205. A lifting plate 207 driven by a lifting assembly 30 is slidably installed on the frame 10. The lifting assembly 30 includes a pair of first mounting plates 31 fixedly installed on the frame 10. An electric push rod 32 is fixedly installed on the first mounting plate 31. The output end of the electric push rod 32 is fixedly connected to the lifting plate 207. A first motor 208 is fixedly installed on the lifting plate 207. A clamping block 209 is fixedly installed on the output shaft of the first motor 208. The clamping block 209 is clamped with the end of the central shaft 205. A filter 210 is arranged on the central shaft 205. A drying mechanism 50 is mounted on the frame 10, and a hot air blower 51 included in the drying mechanism 50 generates a high-temperature airflow to blow the crystals in the filter element 210, thereby accelerating the drying rate thereof; Add the solution to be crystallized into the upper half of the processing cylinder 202 (keep the solution level lower than the high point of the filter 210), then energize the electric heating wire 2022 to heat the solution in the processing cylinder 202 in the heating chamber 2021, evaporate the solvent to reduce the amount of solvent, increase the concentration of the solute, and precipitate crystals between the filter 210 and the partition 203 after it reaches a supersaturated state. While the electric heating wire 2022 is heating, start the first motor 208, and the output shaft of the first motor 208 cooperates with the clamping block 209 to drive the central shaft 205 to rotate. When the central shaft 205 rotates, it drives the stirring member 206 to stir the solution, promotes heat transfer in the solution, and makes the heat more evenly distributed in the entire solution, which helps to eliminate local temperature differences and prevent thermal decomposition or boiling caused by local overheating of the solution. The uniform heat distribution can accelerate the volatilization rate of the solute, shorten the evaporation time, and improve the crystallization efficiency. When the solution is crystallized, the output end of the electric push rod 32 is controlled to extend to drive the lifting plate 207 and the first motor 208 to rise. When the first motor 208 rises, the engaging block 209 is disengaged from the central shaft 205. At the same time, during the lifting plate 207 rising, the tooth block 44 on the tooth plate 42 drives the gear 41 to rotate. When the processing cylinder 202 rotates 180°, the output end of the electric telescopic rod is controlled to shrink and descend. When the output end of the electric telescopic rod shrinks, the lifting plate 207 and the tooth plate 42 are driven to descend. When the tooth block 44 on the tooth plate 42 contacts the gear 41, it retracts into the mounting groove 43 and squeezes the elastic member 45. When the engaging block 209 on the motor output shaft is stuck on the central shaft 205, the solvent can be added to the upper half of the processing cylinder 202 at this time for evaporation and crystallization. The operation is repeated to meet the requirements of continuous crystallization. The original upper half of the processing cylinder 202 is now transformed into the lower half, and the precipitated crystals fall into the filter element 210. At this time, the hot air blower 51 is started to blow the dry air flow to the crystals in the filter element 210, which can dry out the moisture between the crystals, making the crystals easier to store and transport, thereby improving the quality of the finished product. It should be noted that the above steps can be cycled to achieve a good continuous reaction crystallization drying effect.

[0023] The filter element 210 includes a second filter plate 2102 which is detachably rotatable on the central shaft 205. The second filter plate 2102 is slidably connected to a vertical limiting groove on the inner wall of the processing cylinder 202. One end of a connecting rope 2103 is fixedly mounted on the second filter plate 2102. The other end of the connecting rope 2103 is fixedly mounted on the first filter plate 2101. The filtering aperture of the second filter plate 2102 is larger than that of the first filter plate 2101. When the first filter plate 2101 and the second filter plate 2102 are located in the upper half, the solution is located between the partition plate 203 and the second filter plate 2102 for evaporation and crystallization. When the first filter plate 2101 and the second filter plate 2102 in the upper half are transferred to the lower half, the first filter plate 2101 will move away from the second filter plate 2102, and the grains with smaller particle size will fall on the first filter plate 2101 along the pores of the second filter plate 2102, thereby achieving the effect of classification according to the particle size. At the same time, the density of the classified grains is reduced, which is convenient for drying by the dry airflow blown out by the hot air blower 51. The dry airflow of the hot air blower 51 can drive the grains in the first filter plate 2101 and the second filter plate 2102 to shake slightly, which can further improve the classification effect.

[0024] The stirring member 206 includes a slide groove 2061 provided on the central shaft 205, a slide installation strip 2062 is slidably installed in the slide groove 2061, and a scraper 2063 in contact with the inner side of the second filter plate 2102 is slidably installed on the slide installation strip 2062; When the central shaft 205 rotates, the upper half sliding installation bar 2062 and the scraper 2063 are driven to rotate. At this time, the sliding installation bar 2062 is close to the partition 203 to stir the bottom sedimentation solution. At the same time, the scraper 2063 can scrape the inner wall of the second filter plate 2102 while stirring the solution, so as to prevent the crystals from precipitating and adhering to the second filter plate 2102 and being difficult to clean. When the sliding mounting bar 2062 is transferred to the lower half, the sliding mounting bar 2062 will slide in the slide groove 2061 and away from the partition 203 until it contacts the second filter plate 2102. When the central axis 205 drives the sliding mounting bar 2062 to rotate, the grains in the second filter plate 2102 are moved to promote the classification of the grains, thereby improving the classification and drying efficiency.

[0025] The sliding installation bar 2062 is provided with a plurality of through holes 2064, and a stirring bar 2065 is slidably installed in the through holes 2064; The stirring bar 2065 can improve the stirring and mixing effect of the solution and will not affect the position change of the sliding mounting bar 2062.

[0026] An airflow reuse component 60 is provided on the processing cylinder 202. The air outlet pipe 61 included in the airflow reuse component 60 can make the airflow of the hot air blower 51 act on the surface of the processing cylinder 202 after drying and crystallization, so as to keep the processing cylinder 202 warm. The number of the air outlet pipes 61 is several pairs, and the air outlet pipes 61 are all fixedly installed on the processing cylinder 202. The airflow reuse component 60 also includes an active cavity 62 opened in the processing cylinder 202, and several blocking blocks 63 for blocking the air outlet pipe 61 are slidably installed in the active cavity 62. A connecting ring 66 is fixedly installed on the blocking block 63, and a sliding rod 65 is fixedly installed on the connecting ring 66. A sleeve 64 is sleeved on the sliding rod 65, and the sleeve 64 is fixedly installed on the processing cylinder 202. The hot air blower 51 blows out a dry airflow into the lower half area. After passing through the first filter plate 2101 and the second filter plate 2102, the airflow enters the air outlet pipe 61 and blows toward the upper half area of ​​the processing cylinder 202. The high-temperature gas can increase the temperature near the processing cylinder 202, which plays a role in heat preservation for the processing cylinder 202, reduces the workload of the electric heating wire 2022, and reduces the loss of heat energy. When the lower half area turns to the upper half area, the slide rod 65 slides in the sleeve 64 under the influence of gravity and drives the blocking block 63 to move through the connecting ring 66 to block the air outlet pipe 61. Then, the solution can be added to the upper half area for evaporation.

[0027] The drying mechanism 50 includes a pair of positioning plates 52 fixedly mounted on the frame 10, threaded rods 55 are rotatably mounted on the pair of positioning plates 52, and a second mounting plate 53 is commonly threadedly connected to the threaded rods 55, the hot air blower 51 is fixedly mounted on the second mounting plate 53, a second motor 54 is fixedly mounted on the positioning plates 52, an output shaft of the second motor 54 is fixedly connected to the threaded rods 55, and the threaded rods 55 are connected to each other through a belt 56; Before the processing cylinder 202 rotates, the second motor 54 is started, and the second motor 54 cooperates with the threaded rod 55 to drive the second mounting plate 53 and the hot air blower 51 away from the processing cylinder 202, which will not affect the rotation of the processing cylinder 202. After the processing cylinder 202 completes its rotation, the second motor 54 reverses and cooperates with the threaded rod 55 to drive the second mounting plate 53 and the hot air blower 51 to reset, close to the lower half of the processing cylinder 202, to prevent the airflow blown by the hot air blower 51 from escaping to the outside of the processing cylinder 202 and causing waste of heat energy.

[0028] Working principle: add the solution to be crystallized into the upper half of the processing cylinder 202 (keep the solution level lower than the high point of the filter 210), then energize the electric heating wire 2022 to heat the solution in the processing cylinder 202 in the heating chamber 2021, evaporate the solvent to reduce the amount of solvent, increase the concentration of the solute, and precipitate crystals between the filter 210 and the partition 203 after it reaches the supersaturated state. Start the first motor 208 while the electric heating wire 2022 is heating, and the output shaft of the first motor 208 cooperates with the clamping block 209 to drive the central shaft 205 to rotate. When the central shaft 205 rotates, it drives the stirring element 206 to stir the solution, promotes the heat transfer in the solution, and makes the heat more evenly distributed in the whole solution, which helps to eliminate local temperature differences and prevent thermal decomposition or boiling caused by local overheating of the solution. The uniform heat distribution can accelerate the volatilization rate of the solute, shorten the evaporation time, and improve the crystallization efficiency. When the solution is crystallized, the output end of the electric push rod 32 is controlled to extend to drive the lifting plate 207 and the first motor 208 to rise. When the first motor 208 rises, the engaging block 209 is disengaged from the central shaft 205. At the same time, during the lifting plate 207 rising, the tooth block 44 on the tooth plate 42 drives the gear 41 to rotate. When the processing cylinder 202 rotates 180°, the output end of the electric telescopic rod is controlled to shrink and descend. When the output end of the electric telescopic rod shrinks, the lifting plate 207 and the tooth plate 42 are driven to descend. When the tooth block 44 on the tooth plate 42 contacts the gear 41, it retracts into the mounting groove 43 and squeezes the elastic member 45. When the engaging block 209 on the motor output shaft is stuck on the central shaft 205, the solvent can be added to the upper half of the processing cylinder 202 at this time for evaporation and crystallization. The operation is repeated to meet the requirements of continuous crystallization. The original upper half of the processing cylinder 202 is now transformed into the lower half, and the precipitated crystals fall into the filter element 210. At this time, the hot air blower 51 is started to blow the dry air flow to the crystals in the filter element 210, which can dry out the moisture between the crystals, making the crystals easier to store and transport, thereby improving the quality of the finished product. When the first filter plate 2101 and the second filter plate 2102 are located in the upper half, the solution is located between the partition plate 203 and the second filter plate 2102 for evaporation and crystallization. When the first filter plate 2101 and the second filter plate 2102 in the upper half are transferred to the lower half, the first filter plate 2101 will be away from the second filter plate 2102, and the crystals with smaller particle sizes will fall on the first filter plate 2101 along the pores of the second filter plate 2102, thereby achieving the effect of classification according to the particle size. At the same time, the density of the classified crystals is reduced, which is convenient for drying by the dry airflow blown out by the hot air blower 51. The dry airflow of the hot air blower 51 can drive the crystals in the first filter plate 2101 and the second filter plate 2102 to vibrate slightly, which can further improve the classification effect. When the central shaft 205 rotates, the upper half sliding installation bar 2062 and the scraper 2063 are driven to rotate. At this time, the sliding installation bar 2062 is close to the partition 203 to stir the bottom sedimentation solution. At the same time, the scraper 2063 can scrape the inner wall of the second filter plate 2102 while stirring the solution, so as to prevent the crystals from precipitating and adhering to the second filter plate 2102 and being difficult to clean. When the sliding mounting bar 2062 is transferred to the lower half, the sliding mounting bar 2062 will slide in the slide groove 2061 and away from the partition plate 203 until it contacts the second filter plate 2102. When the central shaft 205 drives the sliding mounting bar 2062 to rotate, the crystal grains in the second filter plate 2102 are moved to promote the classification of the crystal grains, thereby improving the classification and drying efficiency. The hot air blower 51 blows out a dry airflow into the lower half area. After passing through the first filter plate 2101 and the second filter plate 2102, the airflow enters the air outlet pipe 61 and blows toward the upper half area of ​​the processing cylinder 202. The high-temperature gas can increase the temperature near the processing cylinder 202, which plays a role in heat preservation for the processing cylinder 202, reduces the workload of the electric heating wire 2022, and reduces the loss of heat energy. When the lower half area turns to the upper half area, the slide rod 65 slides in the sleeve 64 under the influence of gravity and drives the blocking block 63 to move through the connecting ring 66 to block the outlet pipe 61, and then the solution can be added to the upper half area for evaporation; Before the processing cylinder 202 rotates, the second motor 54 is started, and the second motor 54 cooperates with the threaded rod 55 to drive the second mounting plate 53 and the hot air blower 51 away from the processing cylinder 202, which will not affect the rotation of the processing cylinder 202. After the processing cylinder 202 completes its rotation, the second motor 54 reverses and cooperates with the threaded rod 55 to drive the second mounting plate 53 and the hot air blower 51 to reset, close to the lower half of the processing cylinder 202, to prevent the airflow blown by the hot air blower 51 from escaping to the outside of the processing cylinder 202 and causing waste of heat energy.

[0029] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
