Abstract
Description
Technical Field
[0001] This application relates to the field of seawater treatment, and in particular to a mineralized filter for producing low-turbidity water. Background Technology
[0002] Seawater desalination technology has become one of the important means to solve the global water shortage and is widely used in islands, ships, and coastal areas with water scarcity. Seawater desalination technology has undergone several generations of innovation, from the early distillation method to the modern reverse osmosis membrane technology, which has greatly improved the efficiency and water quality of desalination and reduced energy consumption.
[0003] The existing seawater desalination process typically involves pre-filtration, membrane filtration, and mineralization. Pre-filtration removes large particulate impurities from the seawater, while membrane filtration further removes finer pollutants. After these steps, mineralization adds minerals beneficial to human health. Only after mineralization can the water be supplied to the municipal water network for public use. However, during fluctuations in water flow or start-up / shutdown phases, the water flow can easily wash away the mineral filter media, leading to high turbidity in the produced water and affecting the stability of the final product water quality. Summary of the Invention

Multiple buffer plates are provided, and the multiple buffer plates are spaced apart along the height direction of the mineralization pool. Two adjacent buffer plates are respectively fixed to two opposite inner walls of the mineralization pool, and a serpentine buffer channel is formed between the multiple buffer plates.
[0014] By adopting the above technical solutions, the possibility of the ore filter media being washed away during water flow fluctuations or start-up and shutdown phases is reduced, thereby reducing the turbidity of the produced water and improving the stability of the final produced water quality.
[0015] Optionally, the deposition assembly includes helical blades fixed within the mineralization pool, with helical channels formed on the helical blades for water flow.
[0016] By adopting the above technical solution, the spiral channel formed by the spiral blades fixed in the mineralization pool can effectively extend the flow path of the mineralized water, slow down the water flow speed, reduce the impact of the water flow on the mineral filter media, thereby reducing the turbidity of the produced water and improving the stability of the final produced water quality. Moreover, the installation is very convenient and easy.

Each filter media layer includes mineralized filter media for mineralizing water and a support net fixed to the mineralization pool for supporting the mineralized filter media. The two filter media layers are referred to as the first filter layer and the second filter layer, respectively.
[0018] By adopting the above technical solution, the water is mineralized stepwise, and the stability and load-bearing capacity of the mineralized filter media during use are guaranteed. This prevents water flow from impacting the mineralized filter media, reduces the turbidity of the produced water, and improves the stability of the final produced water quality.

The mineralization pool is provided with a drive assembly for driving the first sealing plate to open the first discharge port or driving the second sealing plate to open the second discharge port.
[0022] By adopting the above technical solution, the first and second discharge ports on the support plate can connect the first storage area to the first feed pipe and the second storage area to the second feed pipe, respectively. The first and second sealing plates can rotate inside the support plate to close the first and second discharge ports, respectively. The drive assembly drives the first sealing plate to open the first discharge port or drives the second sealing plate to open the second discharge port, realizing the on-demand feeding of the first and second storage areas to the first and second filter layers, ensuring the uniform distribution and mineralization effect of the mineralized filter material.
[0023] Optionally, the support plate has a first receiving groove for the first sealing plate to be embedded and rotated, and a second receiving groove for the second sealing plate to be embedded and rotated.

[0024] By adopting the above technical solution, the first and second receiving slots opened inside the support plate allow the first and second sealing plates to be embedded and rotated. In conjunction with the drive motor and the reversing component on its output shaft, the rotation direction of the drive motor output shaft can be changed as needed, thereby realizing the rotation of the first or second sealing plate, effectively controlling the opening and closing of the first or second discharge port, and improving the flexibility and reliability of the mineralized filter material feeding process.
[0025] Optionally, the reversing component includes a drive plate slidably connected to the output shaft of the drive motor and a drive member for driving the drive plate to slide on the output shaft of the drive motor.

[0026] By adopting the above technical solution, the driving component can drive the driving plate to slide to cooperate with the first sealing plate or drive the driving plate to slide to cooperate with the second sealing plate, thereby realizing the switching of the rotation direction of the output shaft of the drive motor, and thus realizing the selective rotation of the first sealing plate and the second sealing plate, ensuring the uniform supply of mineralized filter media and effectively reducing the turbidity of the produced water.
[0027] Optionally, a groove is provided on the output shaft of the drive motor, and the driving component includes a slider slidably connected in the groove and fixedly connected to the driving plate, a push spring fixedly connected between one end of the groove and the slider, and an electromagnet for driving the slider to move closer to the direction of the push spring. By controlling the electromagnet to turn on and off, the slider is driven to slide in the groove.
[0028] By adopting the above technical solution, the sliding groove on the output shaft of the drive motor cooperates with the slider, and combined with the action of the push spring and electromagnet, the automatic switching of the drive plate is realized, thereby enabling switching between the first sealing plate and the second sealing plate, accurately controlling the opening and closing of the first and second discharge ports, and effectively improving the automation and stability of the feeding process.
[0029] Optionally, each of the support nets is provided with a leveling component for placing the mineralized filter material on the support net in the storage area.

Detailed Implementation
[0044] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0045] This application discloses a mineralized filter for producing low-turbidity water.
[0046] Example 1
[0047] Reference Figure 1 and Figure 2The low-turbidity water production mineralization filter includes a mineralization tank 1 for containing water during the mineralization process, a filter media layer 11 installed in the mineralization tank 1, a buffer layer 12 disposed in the mineralization tank 1, and a sedimentation layer 13 disposed in the mineralization tank 1. An inlet 14 and an outlet 15 are provided on the mineralization tank 1. The inlet 14 is located on the side wall of the mineralization tank 1 at the lower part of the tank, and the outlet 15 is located on the side wall of the mineralization tank 1 at the upper part. The buffer layer 12 is located between the inlet 14 and the filter media layer 11, so that the water to be mineralized entering from the inlet 14 is buffered by the buffer layer 12 before reaching the filter media layer 11, reducing the impact on the filter media layer 11. The sedimentation component 2 is located between the filter media layer 11 and the outlet 15. The sedimentation component 2 is installed in the sedimentation layer 13. The sedimentation component 2 is used to extend the flow path of the mineralized water, so that the mineralized water can flow out from the outlet 15 after being deposited in the sedimentation layer 13, so that the filter media carried in the water can be fully deposited and the turbidity of the water can be reduced.
[0048] Reference Figure 2 A buffer plate 121 is installed within the buffer layer 12. The buffer plate 121 can be made of ABS plastic, which has good toughness and corrosion resistance. Multiple buffer plates 121 are spaced apart along the height of the mineralization tank 1, with adjacent buffer plates 121 fixed to the inner walls of opposite sides of the mineralization tank 1. The multiple buffer plates 121 form a serpentine buffer channel, allowing water flowing from the inlet 14 to reach the filter media layer 11 via this channel. Within the buffer channel, the water is buffered, resulting in a uniform distribution of pressure and velocity. This design ensures that when water flows through the buffer layer 12, the water pressure acts on the buffer plates 121, buffering the water and making the pressure and velocity relatively uniform. This reduces the impact on the filter media layer 11 and effectively reduces the turbidity of the produced water.
[0049] The filter media layer 11 mainly includes mineralized filter media 111 and a support net 112 for supporting the mineralized filter media 111. The mineralized filter media 111 is made of materials such as seashell filter media and limestone packing, while the support net 112 is made of 304 stainless steel, which has high strength and hardness, as well as good corrosion resistance, to support the mineralized filter media 111. Multiple filter media layers 11 can be arranged at intervals along the height direction of the mineralization tank 1. This application describes two filter media layers 11 as an example, referred to as the first filter layer 113 and the second filter layer 114, respectively. The first filter layer 113 is located below the second filter layer 114, and the diameter of the mineralized filter media 111 in the first filter layer 113 is larger than the diameter of the mineralized filter media 111 in the second filter layer 114. This design of the filter media layer 11 structure can ensure the effective mineralization treatment, enabling graded mineralization of water, while avoiding excessive impact of water flow on the mineralized filter media 111, effectively reducing the turbidity of the produced water.
[0050] The sedimentation component 2 includes a spiral blade 21 installed in the mineralization tank 1. The spiral angle of the spiral blade 21 can be set between 5 and 40 degrees. This application uses a spiral angle of 10 degrees as an example for illustration. A spiral channel 22 is formed at the spiral blade 21 for water to flow through. After the water flows through the mineralization of the filter media layer 11, it will flow along the spiral channel 22 under the action of the spiral blade 21, increasing the flow space of the water. This allows the mineralized filter media 111 carried in the water to be deposited. The deposited mineralized filter media 111 will fall down to the filter media layer 11 along the spiral channel 22, and the deposited water will also reach the outlet 15 along the spiral channel 22 and finally be discharged from the outlet 15. This reduces the problem of the water carrying the filter media out, resulting in high turbidity of the produced water, thereby reducing the probability of the water impacting the mineralized filter media 111 and significantly reducing the turbidity of the produced water.
[0051] Reference Figure 1 and Figure 2 A carbon dioxide tank 16 is provided on one side of the mineralization tank 1 to supply carbon dioxide to the inside of the mineralization tank 1. When water enters the mineralization tank 1 from the inlet 14, the carbon dioxide in the carbon dioxide tank 16 is transported into the mineralization tank 1, so that the carbon dioxide and water are mixed together and reach the filter media layer 11 to slowly dissolve the mineralization filter media 111, so that the dissolved minerals reach the water and realize the mineralization of the water.
[0052] A carbon dioxide inlet 17 is provided on the side wall of the mineralization tank 1, located on the side of the buffer plate 121 facing the water inlet 14. Each buffer plate 121 also has through holes 122, allowing carbon dioxide and water entering the mineralization tank 1 to reach the filter layer both through the buffer channel and through the through holes 122. This results in a more uniform mixing of carbon dioxide and water. The through holes 122 also further buffer the water, reducing excessive impact force on the buffer plate 121 and preventing damage.
[0053] Furthermore, a gas outlet 18 is provided on the mineralization pool 1 for gas discharge. The gas outlet 18 is located above the water outlet 15 to allow gas in the mineralization pool 1 to be discharged.
[0054] The implementation principle of Embodiment 1 of this application is as follows: During use, pure water treated by the seawater desalination device will reach the mineralization tank 1 from the inlet 14. At the same time, carbon dioxide from the carbon dioxide tank 16 will also enter the mineralization tank 1 through the carbon dioxide inlet 17, allowing the carbon dioxide to mix thoroughly with the water. Then, the water will reach the filter media layer 11, dissolving the filter media. The dissolved minerals will be carried away by the water flow. If the water flow carries some filter media, when the water flow reaches the sedimentation layer 13, the water flow will flow along the spiral channel 22. During the flow, the carried filter media will be deposited, reducing the turbidity of the water.
[0055] Example 2
[0056] Reference Figure 2 The difference between this embodiment and embodiment 1 is that a support plate 3 is fixedly connected inside the mineralization tank 1. The support plate 3 is located above the outlet 15. A storage area for storing mineralized filter media 111 is formed inside the mineralization tank 1 above the support plate 3 to achieve the replenishment of mineralized filter media 111.
[0057] Reference Figure 2 and Figure 3 The storage area includes a first storage area 41 for replenishing the first filter layer 113 and a second storage area 42 for replenishing the second filter layer 114. A partition plate 43 is fixedly connected in the mineralization tank 1 to separate the first storage area 41 and the second storage area 42. A first replenishing pipe 44 is provided between the first storage area 41 and the first filter layer 113 to transport the mineralized filter material 111 in the first storage area 41 to the first filter layer 113. A second replenishing pipe 45 is provided between the second storage area 42 and the second filter layer 114 to transport the mineralized filter material 111 in the second storage area 42 to the second filter layer 114. Meanwhile, a first discharge port 46 communicating with the first storage area 41 and a second discharge port 47 communicating with the second storage area 42 are provided on the support plate 3. The mineralized filter material 111 in the first storage area 41 will reach the first feeding pipe 44 through the first discharge port 46, and then reach the first filter layer 113 along the first feeding pipe 44 to replenish the first filter layer 113; while the mineralized filter material 111 in the second storage area 42 will also reach the second feeding pipe 45 through the second discharge port 47, and then reach the second filter layer 114 along the second feeding pipe 45 to replenish the second filter layer 114.
[0058] Reference Figure 2 and Figure 4To better control the opening and closing of the discharge ports, a first sealing plate 48 for sealing the first discharge port 46 and a second sealing plate 49 for sealing the second discharge port 47 are provided inside the support plate 3. Simultaneously, a first receiving groove 31 for the first sealing plate 48 to be inserted and slid into and slide, and a second receiving groove 32 for the second sealing plate 49 to be inserted and slid into and slide, are provided inside the support plate 3. A driving assembly 5 is provided on the mineralization pool 1 to drive the first sealing plate 48 to slide in the first receiving groove 31 and to drive the second sealing plate 49 to slide in the second receiving groove 32. When the driving assembly 5 drives the first sealing plate 48 to slide in the first receiving groove 31, it can open or close the first discharge port 46; when the driving assembly 5 drives the second sealing plate 49 to slide in the second receiving groove 32, it can open or close the second discharge port 47.
[0059] Reference Figure 4 and Figure 5 The first receiving groove 31 and the second receiving groove 32 are both semi-circular, and the first sealing plate 48 and the second sealing plate 49 are both quarter-circular, so that when the second sealing plate 49 is located on one side of the second receiving groove 32, the second sealing plate 49 can block the second discharge port 47, and when the second sealing plate 49 is rotated to the other side of the second receiving groove 32, the second sealing plate 49 opens the second discharge port 47; the sealing process of the first sealing plate 48 on the first discharge port 46 is the same as that of the second sealing plate 49.
[0060] Reference Figure 6 The drive assembly 5 mainly includes a drive motor 51 fixed to the mineralization pool 1 and a commutator 52 installed on the output shaft of the drive motor 51. The output shaft of the drive motor 51 extends through the support plate 3, and the commutator 52 is located inside the support plate 3. The commutator 52 can change the direction of the force on the output shaft of the drive motor 51, so that the drive motor 51 can drive the first sealing plate 48 to rotate or drive the second sealing plate 49 to rotate.
[0061] Reference Figure 6 and Figure 7The reversing component 52 includes a driving plate 521 slidably connected to the output shaft of the drive motor 51, and a driving member 522 that drives the driving plate 521 to slide on the output shaft of the drive motor 51. The driving plate 521 is located between the first sealing plate 48 and the second sealing plate 49. A first locking post 5211 is provided on the side of the driving plate 521 facing the first sealing plate 48. Multiple first locking posts 5211 are spaced around the axis of the output shaft of the drive motor 51. A first slot 481 for inserting the first locking post 5211 is opened on the side of the first sealing plate 48 facing the driving plate 521. A second locking post 5212 is provided on the side of the driving plate 521 facing the second sealing plate 49. Multiple second locking posts 5212 are spaced around the axis of the output shaft of the drive motor 51. A second slot 491 for embedding the second locking post 5212 is opened on the side of the second sealing plate 49 facing the driving plate 521. Under normal conditions, the first sealing plate 48 seals the first discharge port 46, and the second sealing plate 49 seals the second discharge port 47. When it is necessary to replenish the first filter layer 113, the driving component 522 drives the driving plate 521 to slide towards the first sealing plate 48, so that the first locking pin 5211 is inserted into the first locking slot 481. At this time, when the drive motor 51 drives the driving plate 521 to rotate, the driving plate 521 will also drive the first sealing plate 48 to rotate, so that the first sealing plate 48 rotates to open the first discharge port 46. At this time, the mineralized filter material 111 in the first storage area 41 will reach the first replenishment pipe 44 through the first discharge port 46, and from the first replenishment pipe 44 to the first filter layer 113, realizing the replenishment of the first filter layer 113. Conversely, when it is necessary to replenish the second filter layer 114, the driving plate 521 is slid towards the second sealing plate 49 by the driving component 522, so that the second locking post 5212 is inserted into the second locking slot 491.
[0062] The drive motor 51 has a groove 511 on its output shaft. The driving component 522 includes a slider 5221 fixed to the driving plate 521 and slidingly engaged with the groove 511, a push spring 5222 fixed between one end of the groove 511 and the slider 5221, and an electromagnet 5223 for driving the slider 5221 to slide in the direction of the push spring 5222. The electromagnet 5223 is fixed to the end of the groove 511 where the push spring 5222 is installed. A driving block 5224 that can be attracted by the electromagnet 5223 is fixed to the side of the slider 5221 facing the push spring 5222. Under normal conditions, the electromagnet 5223 is de-energized. The driving plate 521 abuts against the second sealing plate 49 under the elastic force of the push spring 5222, and the second locking pin 5212 is also inserted into the second locking slot 491, thereby causing the drive motor 51 to drive the second sealing plate 49 to rotate. When the electromagnet 5223 is energized, it will attract the drive block 5224, which in turn will drive the drive plate 521 to slide toward the first sealing plate 48 until the first locking post 5211 is embedded in the first locking slot 481.
[0063] To facilitate the smooth insertion of the first locking pin 5211 into the first locking slot 481 and the second locking pin 5212 into the second locking slot 491, multiple first locking pins 5211 and 5212 are spaced around the axis of the drive motor 51. Similarly, multiple first locking slots 481 and 491 are spaced around the output shaft of the drive motor 51. Both the first locking pins 5211 and 5212 are slidably engaged with the drive plate 521. Specifically, mounting grooves 523 are provided on both sides of the drive plate 521 for the first locking post 5211 and the second locking post 5212 to be inserted. A fixing spring 524 is fixed between the bottom of the corresponding mounting groove 523 and the first locking post 5211, and between the bottom of the corresponding mounting groove 523 and the second locking post 5212. The fixing spring 524 is fixed between the bottom of the mounting groove 523 and the first locking post 5211, or the fixing spring 524 is fixed between the bottom of the mounting groove 523 and the second locking post 5212. Under normal conditions, under the action of the fixing spring 524, both the first locking pin 5211 and the second locking pin 5212 extend out of the mounting groove 523. When the driving plate 521 abuts against the first sealing plate 48, the first locking pin 5211 corresponding to the first locking groove 481 will be embedded in the first locking groove 481, while the remaining first locking pin 5211 will abut against the side wall of the first receiving groove 31 and be retracted into the mounting groove 523 by the abutment of the side wall of the first receiving groove 31. Moreover, when the driving plate 521 abuts against the first sealing plate 48, the first locking pin 5211 fails to be successfully embedded in the first locking groove 481. As the drive motor 51 drives the driving plate 521 to rotate, the driving plate 521 also drives the first locking pin 5211 to move around the axis of the output shaft of the drive motor 51 until the first locking pin 5211 reaches the first locking groove 481 and is successfully embedded in the first locking groove 481 under the push of the fixing spring 524.
[0064] Reference Figure 6 and Figure 8 When the mineralized filter material 111 in the storage area reaches the filter layer, it will accumulate in the filter layer, resulting in more mineralized filter material 111 on the side of the filter layer closer to the first feed pipe 44 and less mineralized filter material 111 on the side of the filter layer farther from the first feed pipe 44. Therefore, each support net 112 is provided with a leveling component 6 for placing the mineralized filter material 111 in the storage area at the filter layer flat.
[0065] Specifically, the leveling assembly 6 includes a rotating shaft 61 rotatably connected to the support mesh 112, a leveling plate 62 vertically fixed to the end of the rotating shaft 61 away from the support mesh 112, a fixing member 63 for fixing the position of the leveling plate 62 in the mineralization tank 1, and a rotating member 64 for driving the rotating shaft 61 to rotate. The fixing member 63 can fix the position of the leveling plate 62 in the mineralization tank 1, and the rotating member 64 can drive the leveling plate 62 to rotate, thereby causing the leveling plate 62 to push the mineralized filter material 111 near the first feed pipe 44 to the other side.
[0066] The rotating component 64 includes a rotating ring 641 fixed to both ends of the flat plate 62, a rotary motor 642 for driving the rotating ring 641 to rotate, and a transmission component 643 installed between the rotary motor 642 and the rotating ring 641 for driving the rotating ring 641 to rotate via the rotary motor 642. The rotating ring 641 is an external gear ring, and the transmission component 643 includes a gear 6431 rotatably connected to the side wall of the mineralization tank 1 and meshing with the rotating ring 641, and a bevel gear set 6432 installed between the gear 6431 and the output shaft of the rotary motor 642. When the rotary motor 642 starts, it drives the gear 6431 to rotate via the bevel gear set 6432, which in turn drives the rotating ring 641 to rotate. The rotating ring 641 then drives the flat plate 62 to rotate around the axis of the rotating shaft 61, thus smoothing the mineralized filter material 111 and ensuring the flatness of the upper surface of the filter material layer 11.
[0067] Understandably, the first feeding pipe 44 is located on the upper side of the platen 62, so that the material fed by the first feeding pipe 44 can be smoothly smoothed by the platen 62. A pressure sensor is installed on the upper surface of the platen 62 to detect the amount of material fed. When the platen 62 rotates one revolution, if the pressure sensor always detects that there is mineralized material on the platen 62, it proves that the height of the mineralized material in the filter layer 11 is on the upper side of the platen 62. At this time, the first discharge port 46 is closed to complete the feeding.
[0068] Reference Figure 6 and Figure 8Meanwhile, detection components 7 for detecting whether the material level is below a set value are provided on the two opposite inner walls of the mineralization pool 1. The detection components 7 include an infrared transmitter 71 fixed to the inner wall of the mineralization pool 1 and an infrared receiver 72 fixed to the inner wall of the mineralization pool 1. The infrared transmitter 71 and the infrared receiver 72 are located on opposite sides of the mineralization pool 1 and are offset from the axis of the mineralization pool 1. This ensures that the rotating shaft 61 located in the middle of the mineralization pool 1 does not affect the signal emitted by the infrared transmitter 71 to the infrared receiver 72. Under normal conditions, the signal emitted by the infrared transmitter 71 is blocked by the mineralization filter material 111. When the mineralization filter material 111 is below the set value, the height of the mineralization filter material 111 is lower than the infrared transmitter 71. At this time, the signal emitted by the infrared transmitter 71 is received by the infrared receiver 72. When the infrared receiver 72 receives the signal emitted by the infrared transmitter 71, it proves that the height of the mineralization filter material 111 is lower than the set value. At this time, the first sealing plate 48 is controlled to rotate within the first receiving groove 31 so that the first discharge port 46 is opened.
[0069] The fixing component 63 includes a fixing ring 631 placed inside the mineralization pool 1 and a fixing bolt 632 for fixing the fixing ring 631 in the position inside the mineralization pool 1. The fixing bolt 632 passes through the side wall of the mineralization pool 1. In use, the fixing ring 631 is placed directly inside the mineralization pool 1 so that the fixing ring 631 abuts against the rotating ring 641. Then, the fixing bolt 632 passes through the outer wall of the mineralization pool 1 and abuts against the fixing ring 631, thereby fixing the position of the fixing ring 631 inside the mineralization pool 1. This clamps the flat plate 62 and the rotating shaft 61 between the support net 112 and the fixing ring 631.
[0070] In order to ensure that the rotating ring 641 can rotate smoothly and that the water in the mineralization tank 1 will not reach the transmission component 643 from between the rotating ring 641 and the fixed ring 631, a rotating seal is installed between the fixed ring 631 and the rotating ring 641. The rotating seal can be a V-shaped sealing ring, and the V-shaped opening of the V-shaped sealing ring faces the inside of the mineralization tank 1.
[0071] Meanwhile, in order to prevent water in the mineralization pool 1 from reaching the transmission component 643 from the lower side of the rotating ring 641 and causing corrosion to the transmission component 643, a retaining ring is fixedly connected to the lower side of the rotating ring 641. A rotating seal is also fixedly connected between the outer wall of the retaining ring and the inner wall of the mineralization pool 1. The rotating seal is also a V-shaped sealing ring, and the V-shaped opening of the V-shaped sealing ring faces the side away from the rotating ring 641.
[0072] The two rotating seals can seal both sides of the transmission component 643, preventing water in the mineralization pool 1 from reaching the transmission component 643 and reducing the probability of water in the mineralization pool 1 damaging the transmission component 643.
[0073] Understandably, a control unit is also provided. The control unit can be any system capable of signal control, such as a microcontroller or PLC controller. The control unit is connected to the aforementioned electrical components to achieve automated operation.
[0074] The implementation principle of Embodiment 2 of this application is as follows: As the amount of mineralized filter material 111 in the filter layer decreases over time, the signal emitted by the infrared transmitter 71 in the filter layer can be received by the infrared receiver 72. At this time, the control unit controls the solenoid valve to be energized or de-energized, and controls the drive motor 51 to start rotating at a set angle. The drive motor 51 then opens the corresponding first discharge port 46 or second discharge port 47 to replenish the corresponding filter layer. At the same time as replenishment, the rotary motor 642 also starts to drive the plate 62 to rotate, thereby flattening the filter material. When the pressure sensor detects that there is mineralized filter material 111 on the plate 62 for a set time, it indicates that the replenishment has reached the set value. At this time, the drive motor 51 is controlled to rotate in the opposite direction at a set angle, thereby closing the first discharge port 46 or the second discharge port 47. At the same time, the rotary motor 642 is stopped, thus realizing automatic feeding.
[0075] Understandably, in order to control the rotation angle of the drive motor output shaft, an encoder is installed on the output shaft of the drive motor 51 to detect the rotation amount of the drive motor 51 output shaft.
[0076] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
