Description

Technical Field

[0001] The present application relates to the field of seawater desalination, and in particular to a seawater desalination mineralization system. Background Art

[0002] Seawater desalination as a supplement to water resources is an important way to solve the shortage of freshwater resources in coastal areas, and it is also an inevitable requirement for the sustainable development of coastal areas. Although the water after desalination is of high purity and stable supply, while removing salt and harmful ions in the water, it also removes components beneficial to the human body, so desalinated water needs to be post-mineralized. The commonly used ore dissolution method is to dissolve the ore after desalination of seawater with CO2 or sulfuric acid acidification. This method can effectively increase the mineral content of desalinated water, making it closer to the quality of natural water sources.

[0003] The existing ore dissolution method usually includes the following steps: first, desalinated seawater is introduced into the mineralization tower through a pipeline; second, CO2 or sulfuric acid is added inside the mineralization tower to dissolve the ore; finally, the undissolved ore residue is removed by a filtration device. The advantages of this mineralization method are simple operation, low cost, and the ability to effectively increase the mineral content in desalinated water. However, this method has some obvious defects, such as incomplete ore dissolution, low mineralization efficiency, and complex equipment maintenance. Especially in terms of ore replenishment, since the ore tower cannot be automatically replenished, each replenishment requires shutdown operation, which is not only time-consuming and labor-intensive, but also affects production continuity and stability. Summary of the invention

[0004] In order to realize automatic feeding of the ore tower and reduce the complexity of feeding, the present application provides a seawater desalination mineralization system.

[0005] The seawater desalination mineralization system provided in this application adopts the following technical solution: A seawater desalination mineralization system comprises: a tower body, wherein a mineralization area and a material storage area are formed in the tower body, wherein the material storage area is located above the mineralization area, a water inlet and an air inlet are opened on the side wall of the tower body, wherein the water inlet and the air inlet are located at the lower part of the tower body, and a first outlet is arranged on the side wall of the tower body, wherein the first outlet is located between the material storage area and the mineralization area; A bearing plate is fixedly connected in the tower body, the area formed between the bearing plate and the upper part of the tower body is the material storage area, a material outlet is opened on the bearing plate, a sealing plate capable of closing or opening the material outlet is arranged on one side of the bearing plate, and a feeding drive device for driving the sealing plate to move to open or close the material outlet is arranged on the tower body.

[0006] By adopting the above technical solution, under normal conditions, the blocking plate closes the material outlet, so that the tower body can mineralize the desalinated water normally. When there is less mineralized material in the mineralization area, the material feeding drive device can automatically drive the blocking plate to open, so as to open the material outlet, so that the material in the storage area can fall into the mineralization area through the material outlet, realizing automatic material feeding.

[0007] Optionally, the feeding drive device includes a driving motor fixed to the tower body, the output shaft of the driving motor passes through the upper part of the tower body and the supporting plate and is hinged to the sealing plate, two sealing plates are provided, both of which are semicircular, and the circular center of each sealing plate is hinged to the output shaft of the driving motor, and a torsion spring is installed at the hinge axis of each sealing plate for abutting the sealing plate to always abut against the supporting plate to block the material outlet, and a force-applying component is provided on the output shaft of the driving motor for driving the sealing plate to rotate around its own hinge axis to open the material outlet through the rotation of the output shaft of the driving motor.

When refilling is not needed, the drive motor stops rotating, the torsion spring returns to its original position, the plugging plate abuts against the bearing plate again, and the material outlet is closed. This method realizes the automatic refilling function of the ore tower, reduces the frequency of manual intervention, improves production continuity and stability, and reduces the complexity and labor intensity of operation.

When the driving cylinder slides on the driving motor, it can abut against the sealing plate and rotate around its own hinge axis.

[0010] By adopting the above technical solution, when the driving motor rotates, the driving cylinder moves along the thread of the driving motor output shaft, thereby pushing the sealing plate to rotate around the hinge axis to open the material outlet; after the material filling is completed, the coil spring can drive the driving cylinder to move in the opposite direction to achieve reset, thereby closing the material outlet. Automatic material filling is achieved, manual intervention is reduced, and production continuity and stability are improved.

[0011] Optionally, the driving cylinder includes a nut threadedly connected to the output shaft of the driving motor and an abutment cylinder fixedly connected to one end of the nut facing the sealing plate.

This design not only simplifies the mechanical structure and improves the reliability and stability of the system, but also enables precise control, ensuring the smooth progress of the ore feeding process and improving the mineralization efficiency.

[0013] Optionally, a mounting block is fixedly connected to the output shaft of the driving motor, the blocking plate is hinged on two opposite sides of the mounting block, and the abutment cylinder can be sleeved on the mounting block.

[0020] By adopting the above technical solution, it is possible to control all the water to pass through the mineralized area, or part of the water to pass through the mineralized area and part of the water to pass through the regulating area as needed, thereby achieving control of the water mineralization concentration.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses a seawater desalination and mineralization system. Figure 1 and Figure 2 The seawater desalination mineralization system includes a tower body 1, in which a mineralization area 3 and a storage area 2 are formed, the storage area 2 is located on the upper side of the mineralization area 3, a water inlet 11 and an air inlet 12 are opened on the side wall of the tower body 1, the water inlet 11 and the air inlet 12 are located at the lower part of the mineralization area 3, and a first outlet 13 is arranged on the side wall of the tower body 1, and the first outlet 13 is located between the storage area 2 and the mineralization area 3. When in use, water after desalination of seawater enters the tower body 1 from the water inlet 11, and carbon dioxide gas enters the tower body 1 through the air inlet 12. The carbon dioxide gas entering the tower body 1 and the water entering the tower body 1 are mixed and reach the mineralization area 3, thereby mineralizing the water, and the treated water will be discharged from the first outlet 13 to achieve the mineralization of the water. When the material in the mineralization area 3 is less, the material in the storage area 2 will replenish the mineralization area 3, and automatic replenishment is achieved.

[0034] Specifically, a supporting plate 21 is fixedly connected in the tower body 1, and the area formed between the supporting plate 21 and the upper part of the tower body 1 is the above-mentioned material storage area 2. A material outlet 211 is opened on the supporting plate 21, and a sealing plate 22 capable of closing or opening the material outlet 211 is arranged on one side of the supporting plate 21. A feeding drive device 4 is arranged on the tower body 1 for driving the sealing plate 22 to move so as to open or close the material outlet 211.

[0035] Reference Figure 3 and Figure 4 The feeding drive device 4 includes a driving motor 41 fixedly connected to the tower body 1, and the output shaft of the driving motor 41 passes through the upper part of the tower body 1 and the supporting plate 21 and is hinged to the blocking plate 22, wherein two blocking plates 22 are provided, and the two blocking plates 22 are both semicircular, and the two blocking plates 22 form a complete circle, and the circular centers of the two blocking plates 22 are hinged to the output shaft of the driving motor 41, and a torsion spring 42 is installed at the hinge axis of each blocking plate 22 for abutting the blocking plate 22 to always abut on the supporting plate 21 to block the material outlet 211.

[0036] Specifically, a mounting block 43 is fixedly connected to the output shaft of the driving motor 41, two blocking plates 22 are respectively hinged on opposite sides of the mounting block 43, and an auxiliary plate 44 is fixedly connected at the center of each blocking plate 22, and an auxiliary groove 45 for the auxiliary plate 44 to be embedded is provided on the mounting block 43. During installation, the auxiliary plate 44 is directly embedded in the auxiliary groove 45, and the auxiliary plate 44 and the mounting block 43 are connected by a connecting pin to realize the hinged connection between the blocking plate 22 and the output shaft of the driving motor 41.

[0037] At the same time, a force-applying component 46 is provided on the output shaft of the driving motor 41 , which is used to drive the sealing plate 22 to rotate around its own hinge axis through the rotation of the output shaft of the driving motor 41 to open the material outlet 211 .

[0038] Reference Figure 3 A mounting groove 212 is provided on the carrier plate 21, and the force-applying assembly 46 includes a driving cylinder 461 slidably connected in the mounting groove 212 and a coil spring 462 installed between the side wall of the mounting groove 212 and the driving cylinder 461. The driving cylinder 461 is threadedly connected to the output shaft of the driving motor 41, and the driving cylinder 461 can slide on the output shaft of the driving motor 41 until it abuts against the blocking plate 22 and rotates around its own hinge axis to open the material outlet 211.

[0039] Specifically, the driving cylinder 461 includes a nut 4611 threadedly connected to the output shaft of the driving motor 41 and an abutment cylinder 4612 fixed to one end of the nut 4611 toward the sealing plate 22. The abutment cylinder 4612 can slide to be mounted on the mounting block 43 to abut the auxiliary plate 44 to rotate around the axis of the mounting block 43, thereby driving the sealing plate 22 to rotate to open the material outlet 211. Specifically, when it is necessary to open the material outlet 211, the drive motor 41 is directly started, and the output shaft of the drive motor 41 will drive the nut 4611 to rotate, thereby driving the coil spring 462 to contract. When the coil spring 462 contracts to the limit position, the position of the nut 4611 will be fixed, so that the nut 4611 cannot rotate synchronously with the drive motor 41. At this time, when the output shaft of the drive motor 41 continues to rotate, it will drive the nut 4611 to slide on the output shaft of the drive motor 41, so that the abutment cylinder 4612 slides to be sleeved on the mounting block 43, and as the output shaft of the drive motor 41 continues to rotate, the abutment cylinder 4612 will abut on the auxiliary plate 44 and abut the auxiliary plate 44 to rotate relative to the mounting block 43, thereby driving the sealing plate 22 to rotate to open the material outlet 211.

[0040] It is understandable that the sliding distance of the nut 4611 depends on the length of the threaded connection between the nut 4611 and the output shaft of the drive motor 41. When the nut 4611 slides to the lowest position, the abutment cylinder 4612 can drive the two blocking plates 22 to rotate to a vertical state. At this time, when the output shaft of the drive motor 41 continues to rotate, the nut 4611 will not move on the output shaft of the drive motor 41, and will not drive the nut 4611 to rotate or slide.

[0041] When the material in the storage area 2 falls from the material outlet 211 to the mineralized area 3, the mineralized area 3 will be automatically replenished. After the replenishment is completed, the drive motor 41 is controlled to stop. At this time, the rotation force applied to the nut 4611 by the output shaft of the drive motor 41 disappears, and the nut 4611 rotates in the opposite direction under the elastic force of the torsion spring 42, and slides in the opposite direction on the output shaft of the drive motor 41 while rotating until the nut 4611 is reset. At this time, the blocking plate 22 also rotates and resets around the hinge axis with the mounting block 43 under the action of the torsion spring 42, so as to block the material outlet 211 again.

[0042] Reference Figure 3 A slider 463 is fixed to the outer ring of the coil spring 462, and a slide groove 213 is opened on the inner wall of the installation groove 212 for the slider 463 to be embedded and slide, so that when the limit cylinder 32 slides on the output shaft of the driving motor 41, the slider 463 also slides in the slide groove 213, so that the coil spring 462 can slide synchronously with the limit cylinder 32, thereby avoiding the coil spring 462 from being twisted.

[0043] Reference Figure 2 and Figure 3A breaking rod 47 is also fixedly connected to the output shaft of the driving motor 41. The breaking rod 47 is located on the upper side of the supporting plate 21, so that when the material outlet 211 is opened, the breaking rod 47 can rotate synchronously with the output shaft of the driving motor 41, so that the material can be discharged smoothly from the material outlet 211, avoiding the bridging phenomenon that makes it impossible for the material to be discharged smoothly.

[0044] Reference Figure 2 A support plate 31 is fixedly connected in the tower body 1 so that the support plate 31 can support the material. A first mesh hole 311 is provided on the support plate 31 so that water can smoothly pass through the first mesh hole 311 to reach the mineralized area 3. A limiting cylinder 32 is also fixedly connected to the support plate 31. The space formed between the inner side of the limiting cylinder 32 and the support plate 31 is the mineralized area 3, and the space formed between the outer side of the limiting cylinder 32 and the inner wall of the tower body 1 is the regulating area 33. A regulating component 34 is provided in the regulating area 33 for limiting whether water can reach the regulating area 33. The mineralized raw material is located in the mineralized area 3. Under normal conditions, the regulating component 34 blocks the regulating area 33 so that water can smoothly reach the mineralized area 3 for mineralization treatment. After the mineralization is completed, the water will be discharged from the first outlet 13.

[0045] There is also a mixer 5 for mixing the mineralized water, a delivery pipe 52 is connected between the inlet of the mixer 5 and the first outlet 13, a second outlet 51 is provided on the other side of the mixer 5, a stirring paddle 53 is provided in the mixer 5, a reflux pipe 54 is connected to the delivery pipe 52, the other end of the reflux pipe 54 is connected to the tower body 1 and is located at the lower side of the mineralization area 3, and a first control valve 55 is installed on the delivery pipe 52, the first control valve 55 is located between the reflux pipe 54 and the mixer 5; a second control valve 56 is installed on the reflux pipe 54. If the mineralization of the mineralized water is too low, the first control valve 55 can be controlled to be closed or turned down, and the second control valve 56 can be opened, so that the mineralized water reaches the tower body 1 again for secondary mineralization treatment. If the mineralization of the mineralized water is too high, the regulating component 34 can be controlled to open the regulating area 33, so that part of the water entering the tower body 1 is mineralized through the mineralization area 3, and the other part directly reaches the regulating area 33 without mineralization treatment. Then the mineralized water and the unmineralized water are mixed and reach the mixer 5 from the first outlet 13, and the stirring paddle 53 mixes the water to ensure the uniformity of the mineralization of the water.

[0046] It is understandable that a sampling port is connected at the second outlet 51, and the staff can sample the mineralized water through the sampling port to detect the mineralization (turbidity) data of the water. Of course, a water quality detector can also be connected to the sampling port, and the mineralization (turbidity) of the water at the second outlet 51 can be detected by the water quality detector, and the water quality detector is connected to the adjustment component 34 through the PLC controller. When the water quality detector detects that the mineralization (turbidity) of the water in the second outlet 51 is higher or lower than the set value, the PLC controller can automatically control the adjustment component 34 to open or close the adjustment area 33. Among them, the water quality detector can use the existing finished products on the market, as long as it can detect the turbidity of water. When the existing water quality detector on the market detects the turbidity of water, it can automatically obtain the turbidity value of water in about 1 minute, which will not have much impact on the overall water quality mineralization result. Of course, if a detector with a shorter detection time appears on the market, it can also be used in the present application solution so that the PLC controller can control the action of the adjustment component 34 more quickly, making the adjustment component 34 respond more quickly.

[0047] Reference Figure 2 and Figure 5 The regulating assembly 34 includes a retaining ring 341 rotatably connected to the regulating area 33, a second mesh 342 is provided on the retaining ring 341, and a driving assembly 35 for driving the retaining ring 341 to rotate is provided on one side of the tower body 1. Under normal conditions, the retaining ring 341 is located in the tower body 1 and one side is in contact with the support plate 31, and the second mesh 342 on the retaining ring 341 is misaligned with the first mesh 311 on the support plate 31, so that the middle part of the two second meshes 342 on the retaining ring 341 blocks the first mesh 311. When it is necessary to reduce the mineralization of water, the retaining ring 341 can be driven by the driving assembly 35 to rotate to a set angle, so that the second mesh 342 overlaps with the first mesh 311. At this time, the water can directly reach the regulating area 33 without mineralization. By neutralizing the mineralized water and the unmineralized water in the regulating area 33 to reduce the concentration of the mineralized water, the regulation is simpler.

[0048] The driving assembly 35 includes a driving motor 351 fixedly connected to the side wall of the tower body 1, a driving gear 352 fixedly connected to the output shaft of the driving motor 351, and a driven gear 353 fixedly connected to the outer wall of the retaining ring 341. At the same time, a receiving groove 14 for the driving gear 352 to be embedded is provided through the inner and outer walls of the tower body 1. At the same time, an encoder for detecting the rotation amount of the output shaft of the driving motor 351 is installed on the output shaft of the driving motor 351. The driving motor 351 and the encoder are both connected to the PLC controller. The driving gear 352 can be driven to rotate through the driving motor 351, thereby driving the retaining ring 341 to rotate through the driven gear 353. The encoder can detect the rotation angle of the driving motor 351 and transmit the detected data to the PLC controller in real time. When the PLC controller receives the data detected by the encoder and reaches the set value, it controls the driving motor 351 to stop, so as to realize the rotation of the retaining ring 341 to the set angle.

[0049] Reference Figure 2 In order to prevent the mineralized material from falling into the regulating area 33 during the feeding process, a limiting ring 36 is fixed between the outer wall of the limiting cylinder 32 and the inner wall of the tower body 1. The limiting ring 36 is located at the end of the limiting cylinder 32 away from the support plate 31, and the limiting ring 36 is also mesh-shaped. While preventing the mineralized material from falling into the regulating area 33, the water in the regulating area 33 can also reach the first outlet 13 through the limiting ring 36.

[0050] At the same time, in order to realize automatic feeding of the mineralized area 3, a first detection device 6 for detecting whether the mineralized material in the mineralized area 3 is less than the first set value and a second detection device 7 for detecting whether the mineralized material in the mineralized area 3 is higher than the second set value are provided on the tower body 1. The first detection device 6 and the second detection device 7 are both connected to the PLC controller, and the drive motor 41 is also connected to the PLC controller. When the first detection device 6 detects that the mineralized material in the mineralized area 3 is lower than the first set value, the PLC controller will control the drive motor 41 to rotate to drive the blocking plate 22 to rotate, thereby opening the material outlet 211 to realize automatic feeding of the mineralized area 3. When the feeding reaches the second set value, the second detection device 7 will detect it, and at this time the PLC controller will control the drive motor 41 to stop, so as to stop the feeding and complete the automatic feeding action.

[0051] Reference Figure 2The first detection device 6 includes a first transmitter 61 fixedly connected to the inner wall of the tower body 1 and a first receiver 62 fixedly connected to the inner wall of the tower body 1 for receiving the signal sent by the first transmitter 61. Under normal conditions, the mineralized materials in the mineralized area 3 can block the signal transmitted from the first transmitter 61 to the first receiver 62. When the mineralized materials in the mineralized area 3 are reduced to below the first detection device 6, the first receiver 62 can receive the signal transmitted by the first transmitter 61. At this time, it means that the material in the mineralized area 3 is less than the set value, and the PLC controller will automatically control the drive motor 41 to start to start the feeding.

[0052] The second detection device 7 includes a second transmitter 71 fixedly connected to the tower body 1 and a second receiver 72 fixedly connected to the side wall of the tower body 1 and capable of receiving the signal sent by the second transmitter 71. Under normal conditions, the second receiver 72 can receive the signal sent by the second transmitter 71. When the mineralized area 3 is replenished, when the replenished material reaches the second detection device 7, the mineralized material will block the signal sent from the second transmitter 71 to the second receiver 72, indicating that the replenishment is completed. The PLC controller directly controls the drive motor 41 to stop, and the replenishment effect can be completed.

[0053] The implementation principle of a desalination and mineralization system of the present application embodiment is as follows: Under normal conditions, the desalinated water and carbon dioxide gas reach the tower body 1 through the water inlet 11 and the air inlet 12 respectively, and reach the mixing zone from the first outlet 13 after being mineralized in the mineralization zone 3, and then are discharged from the second outlet 51. The staff can detect the mineralization concentration of the water at the sampling port at any time. When the concentration is detected to be too high, the regulating zone 33 can be opened through the regulating component 34, so that part of the water passes through the regulating zone 33 and part of the water passes through the mineralization zone 3. When the concentration is detected to be too low, the first control valve 55 can be controlled to be adjusted down and the second control valve 56 can be adjusted up, so that the mineralized water can reach the tower body 1 again through the reflux pipe 54 to achieve secondary mineralization. When the first detection device 6 detects that the mineralized material in the mineralized area 3 is less than the first set value, the feeding drive device 4 will be controlled to automatically feed the mineralized area 3. When the mineralized material in the mineralized area 3 reaches the second set value, the second detection device 7 detects it, and at this time, the feeding drive device 4 is controlled to stop, completing the automatic feeding operation.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
