Description

Technical Field

[0001] The invention relates to the technical field of copper sulfate cooling crystallization, in particular to a cooling crystallizer for copper sulfate processing and a crystallization method thereof. Background Art

[0002] Copper sulfate has a wide range of uses. It can be used as a fertilizer and a commonly used fungicide. The processing and production of copper sulfate usually involves cooling the high-temperature saturated copper sulfate solution to make it reach a supersaturated state, thereby precipitating copper sulfate crystals.

[0003] During the copper sulfate cooling crystallization process, the outside of the cooling crystallizer is usually surrounded by a cooling medium, so that the temperature of the inner wall of the cooling crystallizer is relatively low, while the temperature inside the copper sulfate solution is relatively high. This temperature difference causes the solution near the inner wall of the cooling crystallizer to reach an oversaturated state first, thereby prompting crystals to precipitate and aggregate in this area. At the same time, the inner wall of the cooling crystallizer provides an attachment point for the copper sulfate crystals. Due to the existence of the attachment point, the crystals formed by the cooling crystallization of copper sulfate will aggregate at the attachment point and increase as the crystallization continues, and then accumulate on the inner wall of the cooling crystallizer. The existence of these attached crystals hinders the contact between the copper sulfate solution and the cooling device, reduces the heat exchange area of ​​the copper sulfate solution, and reduces the cooling effect of the solution, resulting in the inability of the copper sulfate solution to fully crystallize, causing a waste of raw materials. The attached crystals also increase the difficulty of cleaning by subsequent staff.

[0004] At the same time, during the cooling and crystallization process of the copper sulfate solution, there is a temperature difference between the inside and outside of the inner wall of the cooling crystallizer, which causes the water molecules in the copper sulfate solution to condense on the top of the crystallizer. The condensation of water molecules causes the concentration of the copper sulfate solution to change, resulting in uneven crystal growth, destroying the integrity of the crystal structure and reducing the overall quality of the crystals obtained by cooling and crystallizing the copper sulfate.

[0005] In addition, after crystallization is completed, a subsequent filtration step is usually required to separate the crystals from the mother liquor, which increases the complexity of the processing. At the same time, when the mixed solution is discharged, it cannot be guaranteed that all crystals have completely left the interior of the cooling crystallizer, resulting in a waste of crystals.

[0006] Therefore, a cooling crystallizer and a crystallization method for copper sulfate processing are proposed. Summary of the invention

[0054] Embodiment 2:

[0055] The cooling crystallization method for copper sulfate processing comprises the following steps:

[0056] Step 1: Add the prepared copper sulfate saturated solution into the interior of the cooling crystallizer;

[0057] Step 2: cooling the copper sulfate solution in the cooling crystallizer to a suitable temperature through a cooling device, so that it is supersaturated to form stable crystal nuclei;

[0058] Step 3: During the crystallization process, the copper sulfate solution is stirred using a stirring shell plate to cool it evenly to form stable copper sulfate crystals;

[0059] Step 4: After the crystallization is complete, the copper sulfate crystals are separated from the mother liquor and the acid copper crystals are collected.

[0060] The cooling device in step 2 is a cooling water circulation device, and the suitable temperature is 15 to 20 degrees Celsius.

[0061] In step 4, the copper sulfate crystals are separated from the mother liquor by a filter plate.

[0062] The above implementation works as follows:

[0063] The initialization steps are as follows:

[0064] The staff installs the tank top cover 2 and the crystallizer body 1, and injects the copper sulfate solution into the interior of the crystallizer body 1 through the liquid inlet pipe 3. After the injection is completed, the liquid inlet pipe 3 is closed and the external cooling water circulation device is turned on. At this time, the starting rotating block 52 is located at the top of the threaded rod 51.

[0065] The working steps are as follows:

[0066] The following is an explanation of the process of scraping the crystals on the inner wall of the crystallizer body 1 by the scraping component:

[0067] like Figures 4 to 7 As shown, the staff electrically controls the external driving device of the starting rotating block 52 through the external control panel to start the starting rotating block 52 to start rotating. Since the starting rotating block 52 is threadedly connected to the threaded rod 51, the rotation of the starting rotating block 52 causes the starting rotating block 52 to move along the threaded rod 51 toward the bottom of the inner cavity of the crystallizer body 1. In the process of the starting rotating block 52 rotating and moving downward, the rotation of the starting rotating block 52 drives the linkage gear ring 53 to rotate synchronously inside the starting rotating block 52. Since the linkage gear ring 53 and the vibration gear 55 are meshed with each other, the rotation of the linkage gear ring 53 drives the vibration gear 55 to rotate synchronously inside the connecting box 54. Since the resistance rotating block 56 is fixedly connected to the top of the vibration gear 55, the rotation of the vibration gear 55 drives the resistance rotating block 56 away from One end of the vibration gear 55 rotates around the center of the vibration gear 55. When the resistance rotating block 56 rotates to conflict with the linkage long rod 59, the rotation of the resistance rotating block 56 drives the linkage long rod 59 to rotate around the connecting long rod 58. The rotation of the linkage long rod 59 drives the knocking block 511 fixedly connected to it to rotate and deviate, and then knock the inner wall of the stirring shell plate 57. In addition, vibration springs 510 are symmetrically fixedly connected on both sides of the linkage long rod 59. Under the action of the elastic extension and elastic contraction of the vibration springs 510 on both sides, the vibration springs 510 will swing back to their original position. During the swinging of the vibration springs 510, the knocking blocks 511 on both sides of the linkage long rod 59 will alternately knock the inner wall of the stirring shell plate 57, and the knocking of the knocking blocks 511 will cause the stirring shell plate 57 to vibrate.

[0068] At the same time, the rotation of the starting rotary block 52 drives the stirring shell plate 57 to rotate and move downward synchronously. Because the shape of the stirring shell plate 57 away from the starting rotary block 52 is adapted to the shape of the inner wall of the crystallizer body 1 and fits the inner wall of the crystallizer body 1, when the stirring shell plate 57 rotates and moves downward, the stirring shell plate 57 can scrape off the copper sulfate crystals attached to the inner wall of the crystallizer body 1, thereby preventing the crystals attached to the inner wall of the crystallizer body 1 from hindering the contact between the copper sulfate solution and the cooling device, increasing the heat exchange area of ​​the solution, promoting uniform cooling inside the solution, improving the cooling effect, ensuring the full crystallization of the copper sulfate solution, improving production efficiency, and reducing the waste of raw materials. At the same time, scraping off the attached crystals can avoid excessive accumulation of crystals, making the subsequent cleaning work of the staff simpler.

[0069] When the stirring shell plate 57 moves down into the copper sulfate solution in the crystallizer body 1, the rotation of the stirring shell plate 57 can stir the copper sulfate solution, so that the inside of the copper sulfate solution is evenly cooled, which is more conducive to the precipitation of copper sulfate crystals. In addition, when the starting rotating block 52 gradually enters the inside of the copper sulfate solution, the volume of the pushing floating block 513 in the solution increases, so the buoyancy of the pushing floating block 513 gradually increases. Under the action of the buoyancy, the pushing floating block 513 floats upward and extends the connecting telescopic rod 512. At the same time, the upward floating of the pushing floating block 513 will resist the bottom of the linkage gear ring 53 and push the linkage gear ring 53 upward. At this time, the linkage gear ring 53 is out of meshing relationship with the vibration gear 55, and the vibration gear 55 no longer rotates and the stirring shell plate 57 no longer vibrates.

[0070] When the starting rotating block 52 moves to the bottom of the threaded rod 51, the external driving device of the starting rotating block 52 drives the starting rotating block 52 to rotate in the opposite direction and move upward. When the starting rotating block 52 moves to leave the copper sulfate solution, the pushing floating block 513 is no longer affected by the buoyancy of the solution. Under the gravity of the pushing floating block 513 itself, the pushing floating block 513 moves downward and drives the connected telescopic rod 512 to shrink and reset. At the same time, the pushing floating block 513 no longer contacts the bottom of the linkage gear ring 53. The linkage gear ring 53 moves downward under the action of its own gravity until it meshes with the vibration gear 55 again. The rotation of the linkage gear ring 53 drives the vibration gear 55 to rotate. The rotation of the vibration gear 55 drives the resistance rotating block 56 to rotate. The resistance rotating block 56 repeatedly contacts the linkage long rod 59 again, thereby driving the knocking block 511 to continuously knock on the inner wall of the stirring shell plate 57 to vibrate the stirring shell plate 57.

[0071] Because the stirring shell plate 57 is immersed in the copper sulfate solution for a long time and the tiny protrusions on the surface of the stirring shell plate 57 cause the copper sulfate crystals to gather on the surface of the stirring shell plate 57. At the same time, the stirring of the copper sulfate solution by the stirring shell plate 57 causes some of the copper sulfate crystals to leave the surface of the stirring shell plate 57, and also causes some of the copper sulfate crystals to remain on the surface of the stirring shell plate 57. Then, the stirring shell plate 57 can vibrate the copper sulfate crystals attached thereto into the solution through its own vibration, thereby reducing the waste of crystals and preventing the crystals accumulated on the surface of the stirring shell plate 57 from affecting the normal operation of the stirring shell plate 57. When the starting rotating block 52 When the threaded rod 51 moves to the top of the threaded rod 51, the rotation of the starting rotating block 52 drives the stirring shell plate 57 to rotate. The stirring shell plate 57 fits with the tank top cover 2. The rotation of the stirring shell plate 57 can scrape the water droplets condensed by the starting rotating block 52 into the solution at the bottom of the inner cavity of the crystallizer main body 1, thereby preventing the water molecules in the copper sulfate solution from condensing on the inner wall of the tank top cover 2 due to the temperature difference between the inside and outside of the inner wall of the crystallizer main body 1, causing the concentration of the copper sulfate solution to change, thereby causing uneven crystal growth, thereby ensuring the integrity of the crystal structure and improving the overall quality of the crystals obtained by cooling and crystallizing the copper sulfate.

[0072] During the cooling and crystallization process of the copper sulfate solution, the starting rotating block 52 continuously repeats the above-mentioned up and down reciprocating motion, and the crystals of the copper sulfate solution fall onto the surface of the filter plate 66 at the same time.

[0073] The following is an explanation of the process of the lifting assembly lifting the filter plate 66 to the top of the crystallizer body 1:

[0074] like Figures 2 to 3 As shown, when the copper sulfate solution is cooled and crystallized, the staff disassembles the tank cover 2, and at the same time, the staff electrically controls the water outlet valve to open through the external control panel. Due to the filtering effect of the filter plate 66, the solution remaining in the crystallizer body 1 flows out from the liquid outlet pipe 4, and the crystals formed by the cooling and crystallization of the copper sulfate remain on the surface of the filter plate 66. When the solution falls through the blade surface of the propeller 615 with a handle, the flow speed and direction of the solution change, and a force is applied to the propeller 615 with a handle, and the propeller 615 with a handle obtains angular momentum, and starts It rotates inside the liquid outlet pipe 4, and the rotation of the propeller with a handle 615 drives the rotating disk 616 to rotate synchronously. Since the fixed circle 617 is eccentrically fixed on the surface of the rotating disk 616, the rotation of the rotating disk 616 drives the fixed circle 617 to revolve around the center of the rotating disk 616. The rotation of the fixed circle 617 drives the connecting rotating rod 618 to rotate and drives the sliding long rod 613 to slide back and forth inside the air intake pipe 611. The reciprocating sliding of the sliding long rod 613 drives the sliding one-way valve 614 to slide back and forth inside the air intake pipe 611.

[0075] like Figures 8 to 13As shown, when the sliding check valve 614 slides downward inside the air intake pipe 611, the sliding check valve 614 pushes the air inside the air intake pipe 611 to leave the air intake pipe 611 through the vent holes on the air intake pipe 611, and then the area inside the air intake pipe 611 and above the sliding check valve 614 approaches a vacuum state and is in a low-pressure state, while the area below the sliding check valve 614 is still at standard atmospheric pressure. It can be seen from the principle of pressure difference that when there is a pressure difference between the two areas, gas, liquid or other substances will flow from the high-pressure area to the low-pressure area, and then the external air will enter the air intake pipe 611 from the high-pressure area. The air vent on 11 enters the interior of the air intake tube 611 and pushes the sliding one-way valve 614 to rotate toward the top of the air intake tube 611, and the air enters above the sliding one-way valve 614. When the sliding one-way valve 614 slides upward inside the air intake tube 611, the air inside the air intake tube 611 and the air above the sliding one-way valve 614 is compressed, and the gas pressure increases. At this time, the interior of the lifting airbag 65 is under standard atmosphere, and the compressed air inside the air intake tube 611 pushes the fixed one-way valve 612 to rotate toward the filter plate 66, and the air in the air intake tube 611 enters the interior of the lifting airbag 65.

[0076] After the sliding one-way valve 614 has moved back and forth several times inside the air intake pipe 611, since the rotation direction of the fixed one-way valve 612 and the sliding one-way valve 614 are limited to only one-way rotation toward the top of the fixed long tube 61, air continuously enters the interior of the lifting airbag 65, and the interior of the lifting airbag 65 is gradually inflated. Due to the limiting effect of the inner cavity of the fixed long tube 61, the lifting airbag 65 moves vertically upward, and the vertical upward movement of the lifting airbag 65 drives the filter plate 66 to move upward synchronously, and the upward movement of the filter plate 66 stretches the bottom of the filter plate 66 The torsion spring rolling curtain 620 at the top of the filter plate 66 is rolled up. When the filter plate 66 moves to the top of the crystallizer body 1, the staff takes out the crystals, and then the solid-liquid separation step can be quickly completed after the crystallizer body 1 finishes working. A separate filtration step is no longer required subsequently, which improves the processing efficiency of copper sulfate and can move all the crystals out of the interior of the crystallizer body 1, reducing the waste of crystals. At the same time, the crystals are lifted up by the power of the water flow, which saves electricity resources and makes the collection of crystals easier.

[0077] After taking out the crystal, the staff presses the sliding pressing rod 64, which slides downward inside the fixed bracket 62 and compresses the pressing spring 63. The sliding pressing rod 64 slides down to contact the blocking block 69 and pushes the blocking block 69 into the lifting airbag 65. The blocking block 69 slides inside the fixed support plate 68 and stretches the reset spring 610. The bottom of the blocking block 69 no longer blocks the connection between the air outlet pipe 67 and the lifting airbag 65. The gas inside the lifting airbag 65 flows out from the air outlet pipe 67, and the lifting airbag 65 gradually shrinks and moves downward. The filter plate 66 is driven to return to its initial position, and the torsion spring curtain 620 at the bottom of the filter plate 66 is rolled up, and the torsion spring curtain 620 at the top of the filter plate 66 is stretched to seal the gap in the crystallizer body 1 to prevent liquid leakage. At the same time, the airbag 65 is lifted and moved downward so that the sliding pressing rod 64 no longer conflicts with the blocking block 69. Under the elastic extension of the sliding pressing rod 64, the sliding pressing rod 64 slides upward and resets inside the fixed bracket 62. Under the elastic contraction of the fixed support plate 68, the blocking block 69 slides upward and resets inside the fixed support plate 68.
