Description

Technical Field

[0001] The present application relates to the technical field of cooling crystallization, and in particular to a cooling crystallization device for preparing copper chloride by dry method and a method for using the same. Background Art

[0002] In the process of dry preparation of copper chloride, crystallization and purification process is an important step to improve the purity of copper chloride. After the copper chloride powder is generated by dry reaction in the reactor, the collected copper chloride powder is dissolved in an appropriate amount of solvent (such as ethanol or water), and then chilled water or other refrigerant is introduced into the interlayer of the cooling crystallization device. The high-temperature saturated solution in the device is gradually cooled by the heat exchange of the partition wall. As the temperature of the solution decreases, the solution gradually reaches a saturated state and crystals are precipitated. Finally, filtering, washing, drying and other steps are used to remove the solvent and residual impurities to obtain high-purity copper chloride crystals.

[0003] However, the existing cooling crystallization device still has some defects during use: first, in actual use, the heat exchange area of ​​the existing cooling crystallization device is only the inner wall surface of the device, which causes the temperature at the center of the device to be higher than the temperature of the inner wall of the device, that is, the heat dissipation in the device is uneven, which can easily cause insufficient crystallization in the device, resulting in poor cooling crystallization effect; secondly, when crystals precipitate from the solution, the crystals will gather near the components where the refrigerant flows, thereby affecting heat transfer and reducing the efficiency of continuous crystal precipitation.

DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] Embodiment 1, a cooling crystallization device for preparing copper chloride by dry process, comprising:

[0063] like Figure 1-Figure 3 , Figure 5 , Figure 7 The cooling mechanism 1 is used to provide a cooling space for the precipitated crystals. The cooling mechanism 1 includes a cooling shell 11, a cooling pipe 12, an inlet pipe 13, an outlet pipe 14, a support member 15 and a sealing cover 16. Figure 7A cooling interlayer is provided inside the inner wall of the cooling shell 11, and a cooling cavity is provided inside the cooling pipe 12. The bottom end of the cooling pipe 12 is fixedly connected to the bottom center of the cooling shell 11, and the cooling cavity of the cooling pipe 12 is communicated with the cooling interlayer of the cooling shell 11. The outer wall of one end of the inlet pipe 13 is fixedly sleeved with the bottom end of the cooling shell 11, and the outer wall of the other end of the inlet pipe 13 is fixedly sleeved with the cooling cavity of the cooling pipe 12. The outlet pipe 14 is fixedly sleeved on the outer wall of the cooling shell 11, and the interior of the outlet pipe 14 is communicated with the upper end of the cooling interlayer of the cooling shell 11. The refrigerant moves in the inlet pipe 13, the cooling pipe 12, the cooling shell 11 and the outlet pipe 14. Specifically, the refrigerant is discharged into the inlet pipe 13, and then the refrigerant in the inlet pipe 13 is discharged from bottom to top. It is discharged into the cooling cavity of the cooling tube 12, and then the refrigerant in the cooling tube 12 is discharged from top to bottom into the cooling interlayer of the cooling shell 11, and finally the refrigerant is discharged through the outlet pipe 14, which effectively increases the heat exchange area in the cooling mechanism 1, and promotes the uniform cooling of the solution in the cooling shell 11, thereby improving the uniformity and sufficiency of crystallization and enhancing the cooling crystallization effect of the cooling mechanism 1. The outer bottom end of the cooling shell 11 is fixedly sleeved with a support member 15, which can support the cooling shell 11 and ensure the stability of the cooling shell 11. The outer top end of the cooling shell 11 is movably connected with a sealing cover 16, so that the device is in a closed state when working, preventing moisture in the outside air from entering, and avoiding hygroscopic deliquescence of cupric chloride crystals, thereby maintaining the purity and stability of the product.

[0064] like Figure 1-Figure 3 , Figure 5 , Figure 7 , feed pipe 2, two feed pipes 2 are fixedly sleeved on the top of the sealing cover 16, and the two feed pipes 2 are arranged opposite to each other, and are used to transport high-temperature saturated solution into the cooling shell 11.

[0065] like Figure 1-Figure 3 , Figure 5 , Figure 7 , discharge pipe 3, two discharge pipes 3 are fixedly sleeved on the bottom end of the cooling shell 11, and the two discharge pipes 3 are arranged opposite to each other, and are used to discharge the solution carrying crystals in the cooling shell 11, and then separate the crystals from the solution through a separation device (such as a centrifuge, a filter).

[0066] like Figure 1-Figure 5 , Figure 8-Figure 10 The movable mechanism 5 is fixedly provided on the sealing cover 16, and is used to stir the solution to further evenly cool the solution. The movable mechanism 5 includes a movable plate 51, a motor 52, a movable shaft 53, an insert 54 and a stirring assembly 6, such as Figure 8-Figure 10The bottom end of the movable plate 51 contacts the top end of the cooling tube 12, and the top end of the movable plate 51 contacts the bottom end of the sealing cover 16. The movable plate 51 is in the shape of a long plate, and the two ends of the movable plate 51 are adapted to the inner wall of the cooling shell 11, thereby providing conditions for the movable plate 51 to rotate in the cooling shell 11. A motor 52 is fixedly arranged on the top end of the sealing cover 16. The outer wall of the movable shaft 53 is movably sleeved with the sealing cover 16, and one end of the movable shaft 53 is movably connected to the motor 52, and the other end of the movable shaft 53 is fixedly connected to the movable plate 51. When the motor 52 is started, the motor 52 drives the movable shaft 53 to rotate, thereby realizing the rotation of the movable plate 51 in the cooling shell 11. Both ends of the movable plate 51 are provided with movable long holes, and the two movable long holes are asymmetrically arranged. One end of the movable long hole is close to the wall of the cooling shell 11, and the other end of the movable long hole is located in the middle position between the cooling shell 11 and the cooling tube 12. One end of another movable long hole is located in the middle position between the cooling shell 11 and the cooling tube 12, and the other end of the movable long hole is close to the wall of the cooling tube 12, which can provide space for the stirring component 6 to move in the movable plate 51. The block 54 is fixedly embedded in the movable plate 51, and the number of the blocks 54 is two. The two blocks 54 are close to one end of the movable long hole, and the end of the movable long hole is located in the middle position between the cooling shell 11 and the cooling tube 12, which can provide conditions for the synchronous movement of the two stirring components 6. The block 54 is an electromagnet, and the current passed into the block 54 can be controlled to change the magnetic size of the block 54.

[0067] like Figure 1-Figure 5 , Figure 8-Figure 10 , stirring assembly 6, the movable plate 51 is movably connected with the stirring assembly 6 through the movable long hole, which is used to uniformly stir the solution and intermittently move the crystal. The stirring assembly 6 includes a block 61 and a stirring rod 62, such as Figure 9-10 The movable long hole consists of an upper hole and a lower hole. The block 61 is movably connected to the upper hole, and the size of the block 61 is adapted to the upper hole, which can ensure the stability of the stirring component 6 set on the movable plate 51. The block 61 has the same magnetism as the embedded block 54, and the block 61 is connected to the embedded block 54 through a compression spring, which can provide power for the movement of the stirring component 6 in the movable long hole. The stirring rod 62 is in the shape of a long rod, and the stirring rod 62 passes through the lower hole, and the size of the stirring rod 62 is adapted to the lower hole.

[0068] In summary, when the stirring component 6 only stirs the solution, the stirring component 6 is located in the middle position between the cooling shell 11 and the cooling tube 12 due to the tension of the compressed spring, that is, the distance between the stirring component 6 and the cooling shell 11 is equal to the distance between the stirring component 6 and the cooling tube 12, so that the stirring component 6 can evenly stir the solution between the cooling shell 11 and the cooling tube 12 when it rotates slowly, thereby promoting the flow of the solution between the cooling shell 11 and the cooling tube 12, and further promoting the uniform temperature of various places in the cooling mechanism 1. When crystals precipitate and gather near the wall of the cooling shell 11 and the cooling tube 12 and need to be cleaned, the block 54 is energized and the current is gradually increased, so that the block 61 is subjected to the gradually increasing magnetic field. The stirring assembly 6 moves due to the repulsive force, and drives the stirring rod 62 to move until one stirring assembly 6 fits against the wall of the cooling shell 11, and the other stirring assembly 6 fits against the wall of the cooling tube 12, so that the stirring assembly 6 can effectively push the gathered crystals to move when it rotates slowly, and make the crystals away from the walls of the cooling shell 11 and the cooling tube 12, so as to prevent the crystals from affecting the heat transfer between the solution and the cooling shell 11 and the cooling tube 12, thereby improving the efficiency of continuous crystal precipitation. When the stirring assembly 6 needs to be restored to the first state, the current passed into the insert 54 is gradually reduced, so that the stirring assembly 6 will slowly move back under the action of the compression spring. This process effectively protects the stirring assembly 6 and avoids excessive impact that affects the service life of the stirring assembly 6.

[0069] Embodiment 2, on the basis of embodiment 1, a cooling crystallization device for preparing cupric chloride by dry method, further comprising:

[0070] like Figure 8-Figure 10 , the stirring component 6, the stirring component 6 also includes a stirring rod 62 and a gear rod 63, the top end of the stirring rod 62 is movably engaged with the block 61, and the bottom end of the stirring rod 62 is fixedly connected to the gear rod 63, which can provide conditions for the stirring rod 62 to rotate on the block 61.

[0071] like Figure 1-Figure 3 , Figure 5-Figure 8 , Figure 11-Figure 12 The fixing mechanism 4 is movably provided in the cooling housing 11 to guide the solution to be discharged. The fixing mechanism 4 includes a fixing ring 41, an outer tooth ring 42 and an inner tooth ring 43. Figure 11-Figure 12The fixing ring 41 is annular, and the outer ring of the fixing ring 41 is movably connected with the inner wall of the cooling shell 11, and the inner ring of the fixing ring 41 is movably connected with the outer wall of the cooling tube 12, so that the wall surface of the cooling shell 11 and the wall surface of the cooling tube 12 can be effectively cleaned when the fixing ring 41 moves up and down. A fixing ring groove is opened in the middle of the fixing ring 41, and the fixing ring groove corresponds to the middle position between the cooling shell 11 and the cooling tube 12. When the fixing ring 41 moves up, the stirring component 6 is located in the middle position between the cooling shell 11 and the cooling tube 12. At this time, the stirring component 6 does not affect the fixing The ring 41 can move up and down, so when cleaning the cooling mechanism 1, it is not necessary to open the sealing cover 16 and disassemble the movable mechanism 5 to achieve cleaning, thereby improving the convenience of cleaning. The two side walls of the fixed ring groove are inclined, and the bottom surface of the fixed ring groove is composed of four inclined slopes. The bottom surface of the fixed ring groove has two relatively low points and two relatively high points. The two low points of the fixed ring 41 are provided with fixing holes, and the fixing holes of the fixed ring 41 are connected to the discharge pipe 3. By utilizing the shape of the fixed ring 41, the solution in the cooling shell 11 can be effectively discharged through the fixed ring groove and the fixed holes. The solution is discharged into the discharge pipe 3 to achieve full collection of the solution. The outer ring top of the fixed ring 41 is fixedly connected with an outer gear ring 42, and the outer ring of the outer gear ring 42 is movably sleeved with the inner wall of the cooling shell 11, and the inner ring of the outer gear ring 42 is meshed with a gear rod 63. When the stirring rod 62 is attached to the cooling shell 11 and rotates around the cooling shell 11, the gear rod 63 rotates under the push of the outer gear ring 42. The inner ring top of the fixed ring 41 is fixedly connected with an inner gear ring 43, and the inner ring of the inner gear ring 43 is movably sleeved with the inner wall of the cooling tube 12, and the outer ring of the inner gear ring 43 is meshed with another gear rod 63. When the stirring rod 62 is in contact with the cooling tube 12 and rotates around the cooling tube 12, the gear rod 63 self-rotates under the push of the inner gear ring 43. Thus, the self-rotation operation of the two stirring components 6 not only further pushes the crystals away from the cooling shell 11 and the cooling tube 12, effectively reduces the probability of crystals adhering to the wall of the cooling shell 11 and the wall of the cooling tube 12, prevents the crystals from affecting heat transfer, and improves the efficiency of continuous crystal precipitation, but also effectively self-cleans the surface of the stirring component 6, effectively reduces the probability of crystals adhering to the surface of the stirring component 6, and improves the service life of the stirring component 6.

[0072] Embodiment 3, based on embodiment 2, the fixing mechanism 4 further includes:

[0073] like Figure 6-Figure 7 , Figure 11-Figure 12 , the power assembly 7, the bottom end of the fixing ring 41 located at the two high points is provided with a fixing groove, and the fixing ring 41 is provided with a power assembly 7 through the fixing groove, which is used to provide power for pushing the fixing ring 41 to move, and the power assembly 7 includes a power plate 71 and a connecting membrane 72, such as Figure 7 and Fig.12, a set of power components 7 is provided with two power plates 71, and one power plate 71 is fixedly connected to the inner wall of the fixing groove of the fixing ring 41, and the other power plate 71 is fixedly connected to the inner bottom end of the cooling shell 11, and the two power plates 71 are both electromagnets, and the two power plates 71 have the same magnetism. When the two power plates 71 are energized, the magnitude of the current passed into the power plates 71 can be controlled. When it is necessary to move up, the current passed into the power plates 71 is gradually increased, so that the magnetic repulsion between the two power plates 71 is gradually increased, thereby pushing the fixing ring 41 to slowly move up and away from the cooling shell 11. When it is necessary to move down, the current passed into the power plates 71 is gradually reduced, so that the magnetic repulsion between the two power plates 71 is gradually increased. The repulsive force gradually decreases, thereby pushing the fixing ring 41 to slowly move downward and close to the cooling shell 11, thereby ensuring that the fixing mechanism 4 fully cleans the cooling shell 11 and the cooling pipe 12, and reducing the impact force of the fixing mechanism 4 when moving up and down, improving the protection of the fixing mechanism 4, and extending the service life of the fixing mechanism 4. One end of the connecting membrane 72 is fixedly connected to a power plate 71, and the other end of the connecting membrane 72 is fixedly connected to another power plate 71. The connecting membrane 72 is a flexible material that can be deformed vertically (such as polytetrafluoroethylene, silicone, polyethylene), which can effectively improve the buffering effect when the fixing ring 41 moves up and down, and can isolate the power plate 71 from the solution, reducing the mutual influence between the two.

[0074] Embodiment 4, based on embodiment 3, Figure 1-Figure 12 , a method for using a cooling crystallization device for preparing copper chloride by a dry process, comprising the following steps:

[0075] S1. Install the fixing mechanism 4 on the cooling housing 11 , assemble the movable mechanism 5 on the sealing cover 16 , and finally stably install the sealing cover 16 on the cooling housing 11 .

[0076] S2. A high-temperature saturated solution of cupric chloride is discharged into the cooling shell 11 by using the feed pipe 2, and a refrigerant is introduced at the same time, and the moving path of the refrigerant is the inlet pipe 13, the cooling pipe 12, the cooling shell 11, and the outlet pipe 14, which effectively increases the heat exchange area in the cooling mechanism 1, improves the uniformity of heat dissipation in the cooling mechanism 1, thereby uniformly cooling the solution, making the temperature uniform at various locations in the cooling mechanism 1, thereby improving the uniformity and sufficiency of crystallization, and enhancing the cooling crystallization effect of the cooling mechanism 1.

[0077] S3. When only the solution is stirred, the stirring component 6 is located in the middle position between the cooling shell 11 and the cooling tube 12. At this time, the motor 52 is started to slowly rotate the stirring component 6 to effectively stir the solution in the cooling shell 11, promote the flow of solution between the cooling shell 11 and the cooling tube 12, and further promote uniform temperature at various locations in the cooling mechanism 1, thereby improving the crystallization sufficiency and enhancing the cooling crystallization effect of the cooling mechanism 1.

[0078] S4. When crystals gather near the wall of the cooling shell 11 and the wall of the cooling tube 12, under the push of the magnetic repulsion of the insert 54, one stirring component 6 is fitted with the wall of the cooling shell 11, and the other stirring component 6 is fitted with the wall of the cooling tube 12. At this time, the motor 52 is started to make the stirring component 6 rotate slowly, which effectively pushes the gathered crystals to move and keeps the crystals away from the wall of the cooling shell 11 and the cooling tube 12, thereby preventing the crystals from affecting heat transfer and improving the efficiency of continuous crystal precipitation.

[0079] S5. When one stirring component 6 is in contact with the wall of the cooling shell 11 and the other stirring component 6 is in contact with the wall of the cooling tube 12, the two gear rods 63 are respectively meshed with the outer gear ring 42 and the inner gear ring 43, so that the stirring component 6 rotates around the cooling shell 11 and the cooling tube 12 while self-rotating, which not only further pushes the crystal away from the cooling shell 11 and the cooling tube 12, but also effectively self-cleans the stirring component 6, reduces the probability of the crystal adhering to the surface of the stirring component 6, and increases the service life of the stirring component 6.

[0080] S6. After the cooling is completed, the input of the refrigerant is stopped, and the stirring component 6 is located in the middle position between the cooling shell 11 and the cooling pipe 12, and the stirring component 6 is located above the discharge pipe 3. At this time, the discharge pipe 3 is used to discharge the solution in the cooling shell 11.

[0081] S7. When the cooling mechanism 1 needs to be cleaned, clean water is introduced through the feed pipe 2, and then the power assembly 7 is started to push the fixed ring 41 up and down to clean the cooling shell 11 and the cooling pipe 12. Finally, the clean water is discharged through the discharge pipe 3, so that cleaning can be achieved without disassembling the cooling mechanism 1, thereby improving the cleaning convenience of the device.

[0082] The working principle of the method of the present invention is as follows:

[0083] When the cooling mechanism 1 needs to work, after the cooling crystallization device is assembled, the high-temperature saturated solution of cupric chloride is discharged into the cooling shell 11 through the feed pipe 2, and at the same time, the refrigerant is introduced, and the movement path of the refrigerant is the inlet pipe 13, the cooling pipe 12, the cooling shell 11, and the outlet pipe 14, that is, the refrigerant first enters the inlet pipe 13, and then moves from bottom to top to the cooling pipe 12, and then moves from top to bottom to the cooling shell 11, and then moves evenly in the cooling shell 11 and moves to the outlet pipe 14, and finally discharged from the outlet pipe 14, thereby effectively increasing the heat exchange area in the cooling mechanism 1, and improving the uniformity of heat dissipation in the cooling mechanism 1, so as to evenly cool the solution, make the temperature uniform at various places in the cooling mechanism 1, thereby improving the uniformity and sufficiency of crystallization, and enhancing the cooling crystallization effect of the cooling mechanism 1.

[0084] When only stirring the solution, the stirring component 6 is located in the middle position between the cooling shell 11 and the cooling tube 12. At this time, the motor 52 is started to rotate the stirring component 6 slowly. It should be noted that the stirring of the stirring component 6 is intermittent, and the stirring of the stirring component 6 is calculated by the number of circles, that is, the stirring component 6 rotates one circle as one stirring, thereby effectively stirring the solution in the cooling shell 11, promoting the flow of the solution between the cooling shell 11 and the cooling tube 12, and further promoting uniform temperature at various locations in the cooling mechanism 1, thereby improving the sufficiency of crystallization and enhancing the cooling crystallization effect of the cooling mechanism 1.

[0085] When the crystals gather near the wall of the cooling shell 11 and the wall of the cooling tube 12, current is passed through the insert 54, and the current gradually increases, so that under the push of the magnetic repulsion of the insert 54, the block 61 moves until one stirring assembly 6 is in contact with the wall of the cooling shell 11 and the other stirring assembly 6 is in contact with the wall of the cooling tube 12. At this time, the motor 52 is started to rotate the stirring assembly 6 slowly. It should be noted that the stirring of the stirring assembly 6 is intermittent, thereby effectively pushing the gathered crystals to move, so that the crystals are away from the wall of the cooling shell 11 and the cooling tube 12, thereby preventing the crystals from affecting heat transfer and improving the efficiency of continuous crystal precipitation. At the same time, the two gear rods 63 will respectively mesh with the outer gear ring 42 and the inner gear ring 43, so that the stirring assembly 6 rotates while rotating around the cooling shell 11 and the cooling tube 12, which not only further pushes the crystals away from the cooling shell 11 and the cooling tube 12, but also effectively self-cleans the stirring assembly 6, reduces the probability of crystals adhering to the surface of the stirring assembly 6, and improves the service life of the stirring assembly 6.

[0086] After the cooling crystallization is completed, the input of the refrigerant is stopped, and the stirring component 6 is located in the middle position between the cooling shell 11 and the cooling tube 12, and the stirring component 6 is located above the discharge tube 3. At this time, the discharge tube 3 is used to discharge the solution in the cooling shell 11.

[0087] When the cooling mechanism 1 has completed multiple cooling and crystallization operations and its interior needs to be cleaned, clean water is introduced through the feed pipe 2 to rinse the interior of the cooling shell 11 with clean water, and then the stirring component 6 is controlled to be in the middle position between the cooling shell 11 and the cooling tube 12, and the stirring component 6 is aligned with the discharge pipe 3, and then the power component 7 is started to push the fixed ring 41 up and down. It should be noted that the current introduced into the power plate 71 is wavy, that is, when the fixed ring 41 needs to move up, the current is slowly increased, and when the fixed ring 41 needs to move down, the current is slowly reduced to fully clean the residual materials on the wall of the cooling shell 11 and the cooling tube 12, and finally the clean water is discharged through the discharge pipe 3. Thus, the device can be cleaned without disassembling the cooling mechanism 1, which effectively improves the cleaning convenience of the device.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
