Description

Technical Field

[0001] This invention relates to the field of salt production technology, specifically a vacuum deoxygenation device for a salt production system. Background Technology

[0002] Salt production refers to the manufacture of table salt (or industrial salt). The salt industry holds a significant position in the national economy and is an important component of it. Salt is a necessity for human life, a basic raw material for the chemical industry, and also has wide applications in other industrial sectors, agriculture, animal husbandry, and fisheries.

[0003] Brine is the main raw material for salt production, and evaporation is the main unit operation in salt production. During the heating and evaporation process, various gases dissolved in the brine will escape from the system due to the decrease in solubility. Because the soluble gas composition of brine is complex, some brines contain ammonia, some contain hydrogen sulfide, and all brines contain oxygen, nitrogen, etc. If the above gases are not separated in advance, they can easily cause corrosion of the materials used in salt production and reduce heat exchange efficiency. Since the above soluble gases are mainly oxygen, this process is called deoxygenation.

[0004] Vacuum salt production refers to the evaporation of brine in evaporation tanks under different "vacuum" conditions. Due to the pressure drop difference between the tanks, the boiling point decreases, thus allowing heat to be transferred sequentially. This is a modern salt production method that allows "secondary steam" to be reused multiple times.

[0005] The patent document with publication number CN108584985B discloses a vacuum deoxygenation device and method for a salt production system. By introducing an inert gas during the vacuum deoxygenation process to accelerate the removal of oxygen, and by automatically sensing oxygen content, liquid information, and gas pressure information, the device and method can achieve fully automatic vacuum deoxygenation operation of the salt production system. The device and method are characterized by high deoxygenation efficiency and simple operation.

[0006] However, research has revealed certain drawbacks in the use of existing vacuum deoxygenation devices in salt production systems:

[0007] The vacuum deoxygenation device in this salt production system inputs the brine that needs to be deoxygenated into the vacuum deoxygenation device and uses the method of stirring the brine and injecting inert gas to replace the oxygen-containing gas to carry out the deoxygenation work. However, this method is difficult to remove the oxygen dissolved in the brine. In addition, during the deoxygenation process, the inside of the device is kept sealed, making it difficult to keep the brine deoxygenation, brine input and deoxygenated brine output work synchronous, resulting in low work efficiency. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this application provides a vacuum deoxygenation device for a salt production system. By utilizing a motor to drive a driving gear, which in turn rotates a driven gear, the drive shaft inside the driven gear rotates. Simultaneously, the first switching plate, the first sealing plate, the second fixing plate, and the second switching plate rotate. When the internal channel of the first barrier structure is open, brine from the first temporary storage cylinder enters the first temporary storage chamber. As the brine enters the deoxygenation cylinder through the first sealing structure, the channels inside both the second sealing structure and the first barrier structure remain closed. After vacuum deoxygenation of the brine is completed inside the deoxygenation cylinder, the brine is discharged into the second temporary storage chamber through the second sealing structure. The channels inside the first sealing structure and the second barrier structure remain closed. Finally, as the brine is discharged from the second temporary storage chamber into the second temporary storage cylinder, the channels inside the second sealing structure remain closed. This achieves a five-step process—feeding, temporary storage, deoxygenation, temporary storage, and discharge—during continuous rotation of the drive shaft. This facilitates the separation of deoxygenation work from brine feeding and discharge, ensuring high efficiency and thorough deoxygenation of the brine.

[0018] Preferably, when the receiving slot B and the receiving slot A are in a connected state, the first switching plate will switch the top sealing of the water inlet B, while the bottom surface of the second packaging plate will release the top sealing of the slot B, so that the brine is vacuumed from inside the deoxygenation cylinder between the first packaging structure and the second packaging structure by the air extraction pipe, and the oxygen in the brine is removed.

[0023] In summary, the present invention has at least one of the following beneficial technical effects:

[0024] Firstly, the vacuum deoxygenation device for a salt-making system of the present invention utilizes a motor-driven active gear to rotate a driven gear, causing the drive shaft inside the driven gear to rotate. Simultaneously, it controls the rotation of the first switching plate, the first sealing plate, the second fixing plate, and the second switching plate. When the internal channel of the first barrier structure is open, brine from the first temporary storage cylinder enters the first temporary storage chamber. As the brine enters the deoxygenation cylinder through the first sealing structure, the channels inside both the second sealing structure and the first barrier structure remain closed. After vacuum deoxygenation of the brine is completed inside the deoxygenation cylinder, the brine is discharged into the second temporary storage chamber through the second sealing structure. The channels inside the first sealing structure and the second barrier structure remain closed. Finally, as the brine is discharged from the second temporary storage chamber into the second temporary storage cylinder, the channels inside the second sealing structure remain closed. This allows the brine to undergo five steps—feeding, temporary storage, deoxygenation, temporary storage, and discharge—during the continuous rotation of the drive shaft. This facilitates the separation of deoxygenation work from the feeding and discharge of brine, ensuring high efficiency and thorough deoxygenation of the brine.

[0025] Secondly, the vacuum deoxygenation device for a salt production system of the present invention draws air from the inside of the deoxygenation cylinder through an air extraction pipe. When the inside of the deoxygenation cylinder is in a negative pressure state, it is easy to evacuate the inside of the deoxygenation cylinder to remove oxygen from the brine. When the deoxygenated brine is released, inert gas is introduced into the second temporary storage chamber through the air inlet pipe. This can replace the space occupied by the liquid when the deoxygenated brine flows out from the switching outlet B and switching outlet A, ensuring smooth discharge. Attached Figure Description

[0044] Example 1:

[0045] A vacuum deoxygenation device for a salt production system, such as Figures 1-4 As shown, the device includes a deoxygenation cylinder 8, a first temporary storage cylinder 3 assembled to the top of the deoxygenation cylinder 8, and a second temporary storage cylinder 6 assembled to the bottom of the deoxygenation cylinder 8. The top of the first temporary storage cylinder 3 and the bottom of the second temporary storage cylinder 6 are assembled with a cover 2. The surface of the cover 2 at the top is machined with a water inlet pipe 1, and the surface of the cover 2 at the bottom is machined with a water outlet pipe 7. The outer wall of the top of the second temporary storage cylinder 6 is machined with an air inlet pipe 5, and the outer wall of the top of the deoxygenation cylinder 8 is machined with an air extraction pipe 4 (the external structure of this device).

[0046] like Figure 2 As shown, the first temporary storage cylinder 3 has a first barrier structure 9 inside, the second temporary storage cylinder 6 has a second barrier structure 13 inside, one end of the deoxidation cylinder 8 has a first encapsulation structure 11 inside, and the other end of the deoxidation cylinder 8 has a second encapsulation structure 12 inside. With the cooperation of the first barrier structure 9 and the first encapsulation structure 11, a first temporary storage cavity 10 can be formed between the two. The first encapsulation structure 11 and the second encapsulation structure 12 can be formed between the two. The second encapsulation structure 12 and the second barrier structure 13 can be formed between the two.

[0047] like Figure 2 and Figure 3 As shown, the first barrier structure 9 includes a first switching plate 902, a first sealing plate 901 is provided at the bottom of the first switching plate 902, a switching inlet A15 is machined inside the first switching plate 902, and a switching inlet B16 is machined inside the first sealing plate 901.

[0048] like Figure 2 and Figure 4 As shown, the first packaging structure 11 includes a first packaging disk 1101, a first fixing disk 1102 is provided at the bottom of the first packaging disk 1101, a receiving slot A30 is machined inside the first packaging disk 1101, and a receiving slot B21 is machined inside the first fixing disk 1102.

[0049] Specifically, by assembling and fixing the periphery of the first sealing plate 901 to the inner wall of the first temporary storage cylinder 3, the bottom surface of the first switching plate 902 is made to fit with the top surface of the first sealing plate 901, and the outer wall of the first fixing plate 1102 is controlled to be assembled and fixed with the inner wall of the deoxygenation cylinder 8, and the bottom surface of the first sealing plate 1101 is made to fit with the top surface of the first fixing plate 1102, when controlling the communication state between the switching inlet A15 inside the first switching plate 902 and the switching inlet B16 on the first sealing plate 901, the receiving slot B21 and the receiving slot A30 are kept in a vertical state (that is, the first sealing plate 1101 forms a blockage at the top of the receiving slot B21 to restrict the brine from flowing out of the first temporary storage cavity 10 to the bottom), the brine passing through the inlet pipe 1, the first temporary storage cylinder 3, the switching inlet A15 and the switching inlet B16 can be temporarily stored in the interior of the first temporary storage cavity 10 to wait for subsequent vacuum deoxygenation treatment;

[0050] like Figure 2 and Figure 4 As shown, the second packaging structure 12 includes a second packaging disk 1201, a second fixing disk 1202 is provided at the bottom of the second packaging disk 1201, a release slot A31 is machined inside the second packaging disk 1201, and a release slot B22 is machined inside the second fixing disk 1202.

[0051] Specifically, by assembling and fixing the outer wall of the second fixed plate 1202 to the inner wall of the deoxygenation cylinder 8, and the bottom surface of the second encapsulation plate 1201 to be in contact with the top surface of the second fixed plate 1202, when the receiving slot B21 and the receiving slot A30 are in a connected state, the first switching plate 902 will block the top of the switching inlet B16 (restricting the brine at the top from continuing to pass through the interior of the switching inlet A15 and the switching inlet B16 and fall into the interior of the first temporary storage chamber 10), while the bottom surface of the second encapsulation plate 1201 will release the top blockage of the slot B22, so that the brine is only inside the deoxygenation cylinder 8 between the first encapsulation structure 11 and the second encapsulation structure 12, and will not continue to pass through the second encapsulation structure 12 into the interior of the second temporary storage chamber 14;

[0052] Secondly, when removing gas from the brine inside the deoxygenation cylinder 8, air is drawn from inside the cylinder 8 through the extraction pipe 4. This creates a negative pressure inside the cylinder 8, facilitating the creation of a vacuum (the equipment used includes, but is not limited to, a vacuum pump; any device capable of creating a negative pressure in a sealed container is acceptable). This removes oxygen from the brine. (The principle of vacuum degassing (deoxygenation) is Henry's Law: under isothermal and isobaric conditions, the solubility of a gas in a solution is directly proportional to the equilibrium pressure of that gas on the liquid surface; under a certain pressure, the solubility of a gas in a liquid is inversely proportional to temperature; at a certain temperature, the solubility of a gas in a liquid is directly proportional to pressure. Therefore, by increasing the liquid temperature and decreasing the pressure on the liquid surface, dissolved gases can escape, thus achieving degassing. Due to the special nature of the water-cooling system, using a pressure reduction-vacuum generation method can cause dissolved gases in the water to precipitate at a lower temperature, thereby removing gases from the water.)

[0053] like Figure 2 and Figure 3 As shown, the second barrier structure 13 includes a second switching plate 1301, a second sealing plate 1302 is provided at the bottom of the second switching plate 1301, a switching outlet A19 is machined inside the second switching plate 1301, and a switching outlet B18 is machined inside the second sealing plate 1302.

[0054] The outer wall of the second sealing plate 1302 is assembled and fixed with the inner wall of the second temporary storage cylinder 6. The bottom surface of the second switching plate 1301 is in contact with the top surface of the second sealing plate 1302. When the release port B22 and the release port A31 are in a connected state, the first sealing plate 1101 will block the top of the receiving port B21, and the second switching plate 1301 will block the top of the switching outlet B18. The deoxygenated brine flows into the interior of the second temporary storage chamber 14 through the release port B22 and the release port A31 inside the deoxygenation cylinder 8, and remains isolated from the interior of the deoxygenation cylinder 8 and the second temporary storage cylinder 6.

[0055] Meanwhile, when the interior of the switching outlet B18 is in communication with the interior of the switching outlet A19, the second sealing plate 1201 will seal the top of the release slot B22. The deoxygenated brine flows into the interior of the second temporary storage cylinder 6 through the interior of the second temporary storage chamber 14 via the interior of the switching outlets B18 and A19. Meanwhile, inert gas is supplied to the interior of the second temporary storage chamber 14 through the air inlet pipe 5. This can replace the space occupied by the liquid when the deoxygenated brine flows out from the interior of the switching outlets B18 and A19, ensuring smooth discharge.

[0056] Example 2:

[0057] Based on Example 1, such as Figures 1-4As shown, this embodiment describes the specific structure of the first barrier structure 9, the first encapsulation structure 11, the second temporary storage chamber 14, and the second barrier structure 13. The first barrier structure 9, the first encapsulation structure 11, the second temporary storage chamber 14, and the second barrier structure 13 are all equipped with the same drive shaft 17. A driven gear 26 is pinned to the middle of the drive shaft 17. A drive gear 27 is meshed with one side of the driven gear 26. A motor 28 is provided at the bottom of the drive gear 27.

[0058] Specifically, by pinning the drive shaft 17 to the first switching plate 902 on the first barrier structure 9, the first packaging disk 1101 on the first packaging structure 11, the second fixing disk 1202 on the second packaging structure 12, and the second switching plate 1301 on the second barrier structure 13 (the drive shaft 17 is movably connected to the interior of the first sealing plate 901, the first fixing disk 1102, the second packaging disk 1201, and the second sealing plate 1302), during the rotation of the drive shaft 17 (the motor 28 drives the drive gear 27 to drive the driven gear 26 to rotate, causing the drive shaft 17 inside the driven gear 26 to rotate), the first... The rotation of the switching plate 902, the first encapsulation plate 1101, the second fixed plate 1202, and the second switching plate 1301 facilitates control over the communication state between the switching inlet A15 on the first switching plate 902 and the switching inlet B16 on the first sealing plate 901, the communication state between the receiving slot A30 on the first encapsulation plate 1101 and the receiving slot B21 on the first fixed plate 1102, the communication state between the release slot A31 on the second encapsulation plate 1201 and the release slot B22 on the second fixed plate 1202, and the communication state between the switching outlet A19 on the second switching plate 1301 and the switching outlet B18 on the second sealing plate 1302.

[0059] Secondly, such as Figure 7 As shown, the device is in the state of conveying brine into the first temporary storage cylinder 3 through the water inlet pipe 1. When the switching water inlet A15 and the switching water inlet B16 are in the connected state, the first encapsulation plate 1101 forms a blockage at the top of the receiving slot B21, allowing the brine to pass through the interior of the switching water inlet A15 and the switching water inlet B16 and be temporarily stored inside the first temporary storage cavity 10.

[0060] Furthermore, such as Figure 8 As shown, when the brine extraction is completed and temporarily stored in the first temporary storage chamber 10, the first packaging plate 1101 is rotated by the continuously rotating drive shaft 17. When the receiving slot B21 and the receiving slot A30 are in a connected state, the first switching plate 902 blocks the top of the switching inlet B16, and the bottom surface of the second packaging plate 1201 blocks the top of the release slot B22. This allows the brine to wait for the deoxygenation process to take place only inside the deoxygenation cylinder 8 between the first packaging structure 11 and the second packaging structure 12.

[0061] Furthermore, such as Figure 9 As shown, after the deoxygenation of the brine is completed, the continuously rotating drive shaft 17 drives the second packaging plate 1201 and the first packaging plate 1101 to rotate. When the release port B22 and the release port A31 are in a connected state, the first packaging plate 1101 will block the top of the receiving port B21, and the second switching plate 1301 will block the top of the switching outlet B18. The deoxygenated brine flows into the interior of the second temporary storage chamber 14 through the release port B22 and the release port A31 inside the deoxygenation cylinder 8, and remains isolated from the interior of the deoxygenation cylinder 8 and the second temporary storage cylinder 6, so that the interior of the deoxygenation cylinder 8 will not be connected to the outside space instantly.

[0062] Furthermore, such as Figure 10 As shown, when it is necessary to release the deoxygenated brine to the next process, the continuously rotating drive shaft 17 drives the second switching plate 1301 to rotate, so that the interior of the switching outlet B18 and the interior of the switching outlet A19 are in a communication state. In this state, the second sealing plate 1201 seals the top of the release slot B22, and the deoxygenated brine flows into the interior of the second temporary storage cylinder 6 through the interior of the second temporary storage chamber 14 via the interior of the switching outlet B18 and the interior of the switching outlet A19.

[0063] In some examples, a positioning ring seat 24 is integrally formed at the center of the bottom of the first fixed plate 1102 and the second fixed plate 1202, and a bearing 23 is interference-fitted inside the positioning ring seat 24;

[0064] By interfering the drive shaft 17 with the interior of the two bearings 23, stability and smoothness can be ensured when the water outlet pipe 7 controls the first switching plate 902, the first encapsulation plate 1101, the second fixed plate 1202 and the second switching plate 1301 to rotate synchronously.

[0065] Secondly, to facilitate fixing the motor 28 inside the deaerator cylinder 8, so that it can control the rotation of the drive shaft 17 through the driving gear 27 and the driven gear 26, such as... Figure 5 and Figure 6 As shown, a sealing cover 20 is assembled and connected to the center of the bottom of the first fixed plate 1102. A partition 29 is processed on the inner wall of one side of the sealing cover 20. A sealing ring 25 is provided at the center of the bottom of the sealing cover 20. By making the cross section of the sealing ring 25 I-shaped, after the sealing ring 25 is installed inside one end of the sealing cover 20, the sealing ring 25 rotates with the drive shaft 17 and fills the gap between the sealing cover 20 and the drive shaft 17.

[0066] Meanwhile, by mounting the motor 28 to the bottom of the partition 29, the driven gear 26 is located inside the encapsulation cover 20, which facilitates the motor 28 to control the drive gear 27 to drive the driven gear 26 to rotate inside the deoxidizer 8, thereby using the driven gear 26 to control the rotation of the drive shaft 17.

[0067] Specifically, when using the vacuum deoxygenation device in this salt-making system to deoxygenate the brine:

[0068] First, the motor 28 drives the drive gear 27 to rotate the driven gear 26, causing the drive shaft 17 inside the driven gear 26 to rotate (during the rotation of the drive shaft 17, it is supported by the bearing 23 in the center positioning ring seat 24 at the bottom of the first fixed plate 1102 and the second fixed plate 1202), and simultaneously drives the first switching plate 902, the first encapsulation plate 1101, the second fixed plate 1202 and the second switching plate 1301 to rotate.

[0069] In the initial state (e.g.) Figure 7 As shown), the switching inlet A15 inside the first switching plate 902 is in communication with the switching inlet B16 on the first sealing plate 901, so as to support the brine to pass through the inlet pipe 1, the first temporary storage cylinder 3, the brine inside the switching inlet A15 and the switching inlet B16 and be temporarily stored in the first temporary storage cavity 10.

[0070] As the drive shaft 17 continues to rotate, the switching inlet A15 and switching inlet B16 switch to a misaligned state (e.g., ...). Figure 8 As shown), the first switching plate 902 blocks the top of the switching inlet B16, the receiving slot B21 on the first fixed plate 1102 is in communication with the receiving slot A30 on the first encapsulation plate 1101, and the bottom surface of the second encapsulation plate 1201 releases the top of the slot B22, so that the brine is only inside the deoxygenation cylinder 8 between the first encapsulation structure 11 and the second encapsulation structure 12, and will not continue to pass through the second encapsulation structure 12 into the interior of the second temporary storage chamber 14 (in this state, the air is drawn from the inside of the deoxygenation cylinder 8 by the air extraction pipe 4, and when the inside of the deoxygenation cylinder 8 is in a negative pressure state, it is convenient to evacuate the inside of the deoxygenation cylinder 8 and remove the oxygen in the brine).

[0071] Next, receiving slots B21 and A30 switch to a misaligned state (e.g., Figure 9As shown), the first encapsulation plate 1101 blocks the top of the receiving slot B21, and the second switching plate 1301 blocks the top of the switching outlet B18, so that the release slot B22 on the second fixed plate 1202 and the release slot A31 on the 1021 are in a connected state. This can support the deoxygenated brine to flow into the interior of the second temporary storage chamber 14 through the release slots B22 and A31 inside the deoxygenation cylinder 8, and keep it isolated from the interior of the deoxygenation cylinder 8 and the second temporary storage cylinder 6 to avoid mutual interference.

[0072] Subsequently, release slots B22 and A31 switch to the misaligned state (e.g.) Figure 10 As shown), the second encapsulation plate 1201 will seal the top of the release slot B22, and the interior of the switching outlet B18 and the interior of the switching outlet A19 are in a connected state. The deoxygenated brine flows into the interior of the second temporary storage cylinder 6 through the interior of the second temporary storage chamber 14 via the interior of the switching outlet B18 and the switching outlet A19, thus completing the brine deoxygenation process. At any stage, the independent spaces do not affect each other.

[0073] In summary, the deoxygenation of brine using this device involves the following five steps: feeding, temporary storage, deoxygenation, temporary storage, and discharge. Each step is isolated from the previous one, which helps to avoid mutual interference.

[0074] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
