Abstract
Description
Technical Field
[0001] The present application relates to the technical field of wastewater treatment, and in particular to a feeding circulation device and method for preventing mother liquor scaling. Background Art
[0002] Currently, in the process of treating high-salt wastewater (total dissolved solids ≥3.5%) from industries such as landfill leachate, pharmaceuticals, and chemicals, multi-effect evaporation or MVR (mechanical vapor recompression) is usually performed to obtain a mother liquor with high viscosity and high scaling tendency. The mother liquor is then sent to thermal equipment such as scraper dryers and drum dryers for drying and crystallization treatment.
[0003] Among them, the feeding system of traditional drying equipment generally uses a static mother liquor tank to store mother liquor. Salts such as sodium sulfate and sodium carbonate in the mother liquor are prone to form high concentration areas due to gravity sedimentation, especially in the dead corners of the tank body, where they quickly reach an oversaturated state, precipitate crystals and adhere to the tank wall, which can easily lead to equipment scaling and blockage and shortened operating cycle. Summary of the Invention
[0004] The present application provides a feeding circulation device and method for preventing mother liquor scaling, which can effectively reduce the probability of scaling of the mother liquor during storage, thereby effectively extending the operating cycle of the drying equipment.

[0006] By adopting the above technical solution, the circulating pump group allows the mother liquid in the storage space to be distributed on the drying equipment. When the undried mother liquid on the drying equipment flows into the storage space by gravity, it can disturb the mother liquid in the storage space. Part of the mother liquid flows back into the storage space through the disturbance pipe, which can also disturb the mother liquid in the storage space, thereby effectively reducing the probability of scaling of the mother liquid in the storage space, and thus effectively extending the operating cycle of the drying equipment.

The part of the storage space used to collect the mother liquor flowing by gravity and the part of the storage space directly communicating with the reflux port are separated by the partition.
[0008] By adopting the above technical solution, the area where the disturbance effect of the mother liquid flowing into the storage space by gravity on the mother liquid in the storage space is different from the area where the disturbance effect of the mother liquid flowing back into the storage space on the mother liquid in the storage space is different, which can make the disturbance effect on the mother liquid in the storage space more uniform.
[0009] Optionally, the anti-scaling assembly includes a plurality of guide rails, a plurality of disruptors and a drive module; The trajectory of the guide rail is the same as the arc trajectory of the bottom of the storage space and the axis coincides with it. One end of the disruptor is slidably connected to the guide rail and the other end is close to the inner wall of the bottom of the storage space, and the sliding direction of the disruptor is the same as the arc trajectory of the guide rail. The driving module is arranged on the trough body, and is used to drive multiple disruptors to slide relative to the guide rail.
[0010] By adopting the above-mentioned technical solution, when the driving module drives multiple disturbance members to slide along multiple guide rails, the multiple disturbance members can effectively disturb the mother liquor in the storage space, especially at the bottom of the storage space, thereby further effectively reducing the probability of scaling of the mother liquor in the storage space.

[0012] By adopting the above technical solution, when the two disturbing parts are driven by the driving module, the cleaning part can also clean the guide rail and the inner wall of the bottom of the storage space respectively, thereby further reducing the probability of mother liquid scaling on the guide rail surface and the inner wall of the bottom of the storage space, and effectively eliminating scaling.
[0013] Optionally, the driving module includes a linkage structure and a driving member; The linkage structure is arranged on one of the guide rails, and is used to make the two disruptors slide synchronously and in opposite directions relative to the guide rail; the driving member is arranged on the outside of the groove body, and is used to drive one of the disruptors to slide reciprocally relative to the guide rail.
[0014] By adopting the above technical solution, the driving module can conveniently drive the two disturbing members to move synchronously and in opposite directions, thereby effectively improving the uniformity of the disturbing effect of the two disturbing members on the mother liquid at the bottom of the storage space.
[0015] Optionally, a driving portion extends upward from the top of one end of the disturbance member in the length direction, and a clearance space adapted for the driving portion is reserved in the storage space on the side of the partition close to the driving portion, and the driving member is connected to the driving portion to drive the disturbance member to slide relative to the guide rail.
[0016] By adopting the above technical solution, it is possible to facilitate the driving module to achieve the effect of disturbing the mother liquid at the bottom of the storage space through the two disturbing members through the linkage structure.
[0017] Optionally, the driving portion is close to the liquid outlet, and the driving portion contacts an inner wall of the storage space on a side close to the liquid outlet.

[0020] By adopting the above technical solution, when the driving member drives the two disturbing members to move through the driving part, the toggle block can repeatedly toggle the partition to cause it to vibrate, thereby reducing the probability of mother liquor scaling on the partition surface and having the effect of removing scaling.
[0021] Optionally, the anti-scaling component further comprises a plurality of soft and elastic disturbance sheets; The two ends of the disturbance plate are respectively connected to the two adjacent connecting portions of the two disturbance members, the top of the disturbance plate contacts the surface of the guide rail, and the bottom of the disturbance plate is close to the inner wall of the bottom of the storage space.

[0027] The following is combined with Figure 1-9 This application is described in further detail.
[0028] Example 1: Reference Figure 1 and Figure 2 The embodiment of the present application discloses a feeding circulation device for preventing mother liquor from scaling. When used in conjunction with a drying device 1 for drying crystallization mother liquor, it can effectively reduce the probability of scaling of the mother liquor during storage, thereby ensuring the stability of subsequent mother liquor used for spreading on the drying device 1 and effectively extending the operating cycle of the drying device 1.
[0029] The feed circulation system is integrated into the bottom of the drying apparatus 1 and comprises a tank 2, a circulation pump assembly 3, and an anti-scaling assembly 4. The tank 2 is used to store the mother liquor; the circulation pump assembly 3 distributes the mother liquor to the drying apparatus 1; and the anti-scaling assembly 4 is used to reduce the likelihood of scale formation from the mother liquor within the tank 2. In this embodiment, the drying apparatus 1 is preferably a scraper dryer; in other embodiments, the drying apparatus 1 may alternatively be a drum dryer, etc. Since scraper dryers are common in the art, they will not be described in detail here, and are only briefly illustrated in the accompanying drawings.
[0030] Reference Figure 2 and Figure 3The tank body 2 is a rectangular parallelepiped structure as a whole, which is fixedly installed at the bottom of the drying equipment 1. In addition to being used to store the mother liquor, it is also used to collect the mother liquor that is not completely dried and crystallized and flows down from the drying equipment 1 due to gravity, and its length direction is parallel to the length direction of the drying equipment 1. The interior of the tank body 2 is provided with a storage space 21 for storing the mother liquor. The inner wall of the bottom of the storage space 21 is designed to be a smooth arc surface, and the inner walls on both sides of the width direction of the storage space 21 are tapered downward near the arc surface. In this embodiment, it is preferred that the angle formed by the inclination direction of the inner walls on both sides of the storage space 21 near the arc surface is ≥60°, which eliminates the corners and dead corners inside the tank body 2 while reducing the risk of local scaling of the mother liquor in the storage space 21.
[0031] The circulation pump group 3 is used to realize the circulation supply of the mother liquid, and includes a pump body 32 and a distribution pipe 31.
[0032] A liquid outlet 22 communicating with the bottom of the storage space 21 is provided at one end of the tank body 2 in the longitudinal direction. One end of the distribution pipe 31 is fixedly connected to the tank body 2 and communicates with the bottom of the storage space 21 through the liquid outlet 22. The other end of the distribution pipe 31 extends into the interior of the drying device 1 and is used to distribute the material to the drying device 1 (i.e., spray the mother liquid).
[0033] The pump body 32 is fixedly mounted on the distribution pipe 31 and is used to drive the mother liquid in the storage space 21 into the distribution pipe 31 and flow along the distribution pipe 31. In this embodiment, the pump body 32 is preferably a centrifugal pump. When activated, it can pump the mother liquid at the bottom of the storage space 21 and transport it through the distribution pipe 31 to the drying equipment 1 for drying after pressurization. Since centrifugal pumps are common in the prior art, they will not be described in detail here, and they are only briefly shown in the drawings.
[0034] The anti-scaling assembly 4 includes a disturbance tube 41 and a partition 42. The disturbance tube 41 is used to allow the mother liquid to reflux and disturb the mother liquid in the storage space 21; while the partition 42 is used to divide the mother liquid in the storage space 21 into zones to improve the uniformity of the disturbance effect on the mother liquid in the storage space 21.
[0035] A reflux port 23 is provided on one side of the tank body 2 away from the liquid outlet 22 along its own length direction, and the reflux port 23 is communicated with the bottom of the storage space 21; one end of the disturbance tube 41 is fixedly connected to the tank body 2 and communicated with the bottom of the storage space 21 through the reflux port 23, and the other end of the disturbance tube 41 is fixedly connected and communicated with the distribution pipe 31, and the position where the disturbance tube 41 is connected and communicated with the distribution pipe 31 is located between the pump body 32 and one end of the distribution pipe 31 close to the drying equipment 1.
[0036] At this time, when the circulation pump group 3 is running, the pump body 32 drives the mother liquor in the storage space 21 to flow through the distribution pipe 31, and a part of the mother liquor will flow back along the disturbance pipe 41 and through the reflux port 23 into the bottom of the storage space 21. The refluxed mother liquor can impact the mother liquor at the bottom of the storage space 21, thereby having a disturbance effect. Disturbing the mother liquor in this area can effectively prevent the salt in the mother liquor from settling and the local concentration from being too high and causing scaling, thereby significantly inhibiting the scaling tendency of the mother liquor in this area.
[0037] At the same time, since the circulation pump group 3 runs along with the operation of the drying equipment 1, the mother liquor distributed on the drying equipment 1 by the distribution pipe 31 will flow back to the storage space 21 by gravity because it is not completely dried. The mother liquor falling into the storage space 21 due to gravity will also impact the liquid surface in the storage space 21 and the mother liquor below it, thereby having a disturbing effect, thereby effectively suppressing the tendency of the mother liquor to form scale in the storage space 21.
[0038] The partition 42 is an overall rectangular plate-like structure, fixedly mounted within the tank body 2 and positioned vertically across its width within the storage space 21. The top of the partition 42 extends above the level of the mother liquor within the storage space 21, and a certain distance exists between the bottom of the partition 42 and the inner wall of the bottom of the storage space 21. This allows mother liquor on either side of the partition 42 in the storage space 21 to flow through the space below the partition 42. In this embodiment, the partition 42 is preferably centered within the storage space 21 along the width of the tank body 2, meaning that the spaces on both sides of the storage space 21 divided by the partition 42 are identical.
[0039] The mother liquor flowing by gravity on the drying equipment 1 will fall into the space on one side of the partition 42, and the position where the liquid outlet 22 and the reflux port 23 communicate with the storage space 21 is located on the other side of the partition 42. Therefore, the partition 42 will physically separate the falling area of the mother liquor in the storage space 21 for receiving the mother liquor flowing by gravity and the area for directly receiving the mother liquor refluxed by the reflux pipe in the top area of the storage space 21. After the partition 42 plays a separating role, the mother liquor flowing by gravity from the drying equipment 1 will be used to impact and disturb the mother liquor in the area on one side of the partition 42 in the storage space 21, and the mother liquor flowing back through the disturbance pipe 41 will be used to impact and disturb the mother liquor in the area on the other side of the partition 42 in the storage space 21, so that the disturbance effect of the anti-scaling component 4 on the mother liquor in the two areas on both sides of the partition 42 does not interfere with each other near the liquid surface, avoiding energy cancellation. At the bottom of the storage space 21, the mother liquor can be slowly mixed through the space below the partition 42. This design can ensure that the disturbance energy in the mother liquor in the storage space 21 covers the entire storage space 21 more evenly and efficiently, thereby effectively reducing the disturbance blind spot.
[0040] The implementation principle of a feeding circulation device for preventing mother liquor scaling in the embodiment of the present application is as follows: In the process of the circulating pump group 3 driving the mother liquor in the storage space 21 to flow along the distribution pipe 31 to distribute the material to the drying equipment 1, part of the mother liquor in the distribution pipe 31 will enter the bottom of the storage space 21 along the disturbance pipe 41 through the reflux port 23, thereby disturbing the mother liquor in the storage space 21; and part of the mother liquor distributed on the drying equipment 1 that has not dried will flow into the storage space 21 by gravity, thereby also disturbing the mother liquor in the storage space 21; thereby effectively reducing the probability of scaling of the mother liquor in the storage space 21, thereby effectively extending the operating cycle of the drying equipment 1.
[0041] Example 2: Reference Figure 4 and Figure 5 The present embodiment differs from Example 1 in that, targeting the bottom of the storage space 21, a high-risk area for mother liquor scaling, the anti-scaling assembly 4 further includes multiple guide rails 43, multiple disruptors 44, and a drive module 45 for mechanically disturbing the mother liquor. The disruptors 44 are used to mechanically disturb the mother liquor at the bottom of the storage space 21; the guide rails 43 are used to guide the disruptors 44 within the bottom of the storage space 21; and the drive module 45 is used to power the disruptors 44. In this embodiment, the anti-scaling assembly 4 preferably includes two disruptors 44, each preferably having a frame structure, and having different structures.
[0042] Reference Figure 6 and Figure 7 The guide rail 43 is a strip structure with an arc trajectory as a whole. It is fixedly installed on the trough body 2 and is located in the storage space 21, and it is located below the partition 42; the arc trajectory of the guide rail 43 is perpendicular to the length direction of the trough body 2, and its arc trajectory is the same as the arc trajectory of the arc surface at the bottom of the storage space 21, and the axis coincides; the guide rails 43 are symmetrically distributed relative to the partition 42 in the storage space 21, and multiple guide rails 43 are distributed at equal intervals along the length direction of the trough body 2 in the storage space 21.
[0043] Reference Figure 7 and Figure 8 Both disruptors 44 have multiple connecting portions 441 for sliding connection with the guide rails 43. The multiple connecting portions 441 of the two disruptors 44 correspond one-to-one to the multiple guide rails 43, and the connecting portions 441 of the same disruptor 44 are slidingly connected to the multiple guide rails 43 at intervals; the end of the connecting portion 441 is slidingly connected to the guide rail 43, and its sliding direction is the same as the arc trajectory of the guide rail 43.
[0044] Both disruptors 44 have a cleaning portion 442 for cleaning the scaled mother liquor. The multiple connecting portions 441 of each disruptor 44 are connected through the cleaning portion 442 to form an integrated structure. The multiple connecting portions 441 are evenly spaced along the length direction of the cleaning portion 442, and the length direction of the connecting portions 441 is perpendicular to the length direction of the cleaning portion 442.
[0045] Reference Figure 8 and Figure 9 , wherein the cleaning portion 442 of a disturbing member 44 is in contact with and abuts against the top surfaces of the multiple guide rails 43 corresponding to the two disturbing members 44. During its movement along the multiple guide rails 43 corresponding to itself, its cleaning portion 442 can not only clean the mother liquid scale on the top surfaces of the multiple guide rails 43 corresponding to itself, but also clean the mother liquid structure on the top surfaces of the multiple guide rails 43 corresponding to the other disturbing member 44; and, the end of the connecting portion 441 of the disturbing member 44 away from the cleaning portion 442 is close to the inner wall of the bottom of the storage space 21 and there is a certain distance between it and the inner wall of the bottom of the storage space 21, so as to improve the smoothness of the movement of the disturbing member 44 in the storage space 21.
[0046] In addition, the cleaning portion 442 of the other disruptor 44 contacts and abuts against the inner wall of the bottom of the storage space 21, and its two ends are close to the two sides of the length direction of the storage space 21. During its movement along the corresponding multiple guide rails 43, its cleaning portion 442 can clean the inner wall of the bottom of the storage space 21 to remove the mother liquid scale; and the distance between the end portions of the multiple connecting portions 441 of the other disruptor 44 and the inner wall of the bottom of the storage space 21 is sufficient for the cleaning portion 442 of the disruptor 44 to move through, so as to effectively avoid the situation where the two disruptors 44 interfere with each other.
[0047] Reference Figure 5 and Figure 7 The driving module 45 is used to drive the two disrupting members 44 to move synchronously and in opposite directions relative to their corresponding guide rails 43, that is, when one disrupting member 44 moves along its corresponding guide rail 43 in one direction to an extreme position, the other disrupting member 44 will move along its corresponding guide rail 43 in the other direction to an extreme position.
[0048] Reference Figure 5 and Figure 8 The driving module 45 includes a linkage structure 451 and a driving member 452. The linkage structure 451 is used to form a linkage relationship between the two disrupting members 44 to achieve the effect of synchronous and reverse movement; the driving member 452 is used to provide power for the movement of the two disrupting members 44.
[0049] The linkage structure 451 is installed on a guide rail 43 and includes two movable parts 4511 and a synchronous belt 4512 .
[0050] The movable part 4511 is movably connected to the guide rail 43, and its movable direction is the same as the arc trajectory of the guide rail 43; the two movable parts 4511 correspond to the two disturbing parts 44 one by one, and the movable parts 4511 are fixedly connected to the corresponding disturbing parts 44, and the two movable parts 4511 are respectively close to the top and bottom of the guide rail 43.
[0051] The synchronous belt 4512 is wound and installed on the guide rail 43 . The two movable parts 4511 are fixedly connected to the synchronous belt 4512 at the same time, and the two movable parts 4511 are respectively located at the top and bottom of the synchronous belt 4512 .
[0052] At this time, the movement of one agitating member 44 relative to the guide rail 43 can drive the other agitating member 44 to move synchronously in the opposite direction relative to the guide rail 43 through the linkage structure 451. In this embodiment, the agitating member 44 whose cleaning portion 442 contacts the guide rail 43 is preferably fixedly connected to the movable member 4511 near the top of the guide rail 43, and the other agitating member 44 is fixedly connected to the movable member 4511 near the bottom of the guide rail 43. Since the linkage structure 451 having the above-mentioned function is common in the prior art, it will not be described in detail here, and it will only be briefly illustrated in the drawings.
[0053] Reference Figure 5 and Figure 7 The driving member 452 is fixedly mounted on one side of the tank body 2 in the longitudinal direction. It is located on the same side of the tank body 2 as the liquid outlet 22 and is located above the liquid outlet 22. It is used to drive a disturbance member 44 to move relative to the guide rail 43. In this embodiment, the driving member 452 is preferably used to drive the disturbance member 44 that contacts the guide rail 43 to move.
[0054] A driving portion 443 extends outward from the disrupting member 44, which is driven by a driving member 452. The length of the driving portion 443 is perpendicular to the length of the corresponding cleaning portion 442 and parallel to the length of the corresponding connecting portion 441. One end of the driving portion 443 is fixedly connected to one end of the corresponding cleaning portion 442 along the length direction, and the other end of the driving portion 443 is located on the axis of the curved surface at the bottom of the storage space 21 and connected to the driving member 452. The driving member 452 drives the corresponding disrupting member 44 to swing back and forth about the axis of the curved surface at the bottom of the storage space 21 via the driving portion 443, thereby driving the corresponding disrupting member 44 to reciprocate relative to the guide rail 43. In this embodiment, the driving member 452 is preferably a servo motor. Since the driving member 452 with the above-mentioned functions is common in the prior art, it will not be described in detail here, and it will only be briefly illustrated in the accompanying drawings.
[0055] Reference Figure 6 and Figure 7One end of the partition 42 in the length direction contacts and abuts against the inner wall of the storage space 21 near the reflux port 23, and a clearance space 24 for the driving part 443 to swing through is formed between the other end of the partition 42 in the length direction and the inner wall of the storage space 21 near the liquid outlet 22.
[0056] Because the mother liquid in the storage space 21 has a tendency to flow toward the liquid outlet 22 under the action of the circulation pump assembly 3, the inner wall of the storage space 21 near the liquid outlet 22 is one of the hardest hit areas for mother liquid scaling. One side of the driving portion 443 abuts against the inner wall of the storage space 21 near the liquid outlet 22. Therefore, when the driving member 452 drives the driving portion 443 to swing relative to the tank body 2, the driving portion 443 can effectively suppress the tendency of mother liquid to scale on the inner wall of the storage space 21 near the liquid outlet 22, and can also remove the scaling of the mother liquid on the inner wall of the storage space 21 near the liquid outlet 22.
[0057] Furthermore, since the surfaces on both sides of the partition 42 have the largest contact area with the mother liquid in the storage space 21, the surface of the partition 42 immersed in the mother liquid in the storage space 21 is also one of the areas most susceptible to mother liquid scaling. Therefore, the partition 42 preferably has a tendency to vibrate relative to the tank body 2 when subjected to external forces, and the driving portion 443 preferably has a toggle block 444 on the side near the partition 42 for toggling the partition 42 to drive it to vibrate.
[0058] The toggle block 444 is elastic and fixedly connected to the driving portion 443. As the driving portion 443 swings, the toggle block 444 intermittently toggles the partition 42, causing the partition 42 to vibrate relative to the tank body 2. In this embodiment, the partition 42 is preferably fixedly connected to the tank body 2 via a structure extending outward from its top, and the contact point between the toggle block 444 and the partition 42 is near the bottom of the partition 42. The toggle block 444 is preferably made of rubber.
[0059] At this time, as the driving portion 443 swings relative to the tank body 2 and passes through the clearance space 24, the shifting block 444 on the driving portion 443 intermittently shifts the partition 42, causing the partition 42 to intermittently generate continuous small-amplitude vibrations. During the vibration of the partition 42, the vibration can not only effectively shake off the mother liquid scale on the surface of the partition 42 and prevent the mother liquid from further scaling on the surface of the partition 42, but also disturb the mother liquid around the partition 42 through the vibration and transfer the vibration energy to the mother liquid in the storage space 21, further enhancing the disturbance effect on the mother liquid in the storage space 21.
[0060] Reference Figure 7 and Figure 8 Furthermore, the anti-scaling component 4 preferably also includes a plurality of disturbance plates 46 for enhancing the disturbance effect on the mother liquid located at the bottom of the storage space 21 .
[0061] The agitator 46 is flexible and elastic, and can bend and deform freely. The two ends of the agitator 46 in the longitudinal direction are fixedly connected to adjacent connecting portions 441 on the two agitator members 44, so that a agitator 46 is connected between the connecting portion 441 of one agitator member 44 and the adjacent connecting portion 441 of the other agitator member 44. After installation, the top of the agitator 46 contacts and abuts the surface of the bottom of the guide rail 43, and the bottom is close to the inner wall of the bottom of the storage space 21. In this embodiment, the agitator 46 is preferably made of rubber material, and the bottom of the agitator 46 preferably contacts the top surface of the cleaning portion 442 used to clean the inner wall of the bottom of the storage space 21.
[0062] When the two disrupting members 44 move in opposite directions relative to the guide rail 43 to their extreme positions, the disrupting plate 46 is in a fully extended state; when the two disrupting members 44 move relative to the guide rail 43 to a position where they are aligned along the length direction of the trough body 2, the disrupting plate 46 is in a state with the maximum bending deformation, and then the disrupting plate 46 can deform and recover under the action of its own elasticity.
[0063] In the process of the driving module 45 driving the two disturbance members 44 to move, the multiple disturbance plates 46 can not only enhance the disturbance effect on the mother liquor at the bottom of the storage space 21, but also inhibit and remove the scaling of the mother liquor on the surface of the bottom of the guide rail 43 and the surface of the top of the cleaning part 442 for cleaning the inner wall of the bottom of the storage space 21.
[0064] In addition, as the disturbance sheet 46 repeatedly bends, deforms, and recovers as the two disturbance members 44 move, it can also disturb the mother liquid at the bottom of the storage space 21, thereby further reducing the probability of the mother liquid scaling on the inner wall at the bottom of the storage space 21.
[0065] The implementation principle of a feeding circulation device for preventing mother liquor scaling in the embodiment of the present application is as follows: When the circulating pump group 3 drives the mother liquid in the storage space 21 to flow along the distribution pipe 31 to distribute the material to the drying device 1, part of the mother liquid in the distribution pipe 31 will flow along the disturbance pipe 41 through the reflux port 23 into the bottom of the storage space 21, thereby disturbing the mother liquid in the storage space 21. In addition, part of the mother liquid distributed on the drying device 1 will flow into the storage space 21 by gravity without drying, thus also disturbing the mother liquid in the storage space 21. At the same time, the anti-scaling component 4 keeps running, and the driving module 45 drives the two disturbing members 44 to move synchronously and in opposite directions along the guide rails 43, thereby mechanically disturbing the mother liquid in the storage space 21. During this process, the cleaning parts 442 on the two disturbing members 44 can respectively inhibit the scaling of the mother liquid and remove the scaling of the mother liquid on the multiple guide rails 43 and the inner wall of the bottom of the storage space 21. In addition, the toggle block 444 on the driving part 443 of one disturbing member 44 can intermittently toggle the partition 42, thereby inhibiting the scaling of the mother liquid on the partition 42 and removing the scaling of the mother liquid on the partition 42 through the vibration of the partition 42, and can also disturb the mother liquid in the storage space 21 through the transmission of vibration energy. In addition, the multiple disturbing plates 46 bend, deform and move at the bottom of the storage space 21 as the two disturbing members 44 move, which can further enhance the disturbance effect on the mother liquid at the bottom of the storage space 21, thereby effectively reducing the probability of scaling of the mother liquid in the storage space 21, and thus effectively extending the operation cycle of the drying equipment 1.
[0066] Example 3: Reference Figure 2 and Figure 3 The present application discloses a method for preventing mother liquor scaling, which is used in the feeding circulation step of the drying equipment 1. Based on a feeding circulation device for preventing mother liquor scaling disclosed in Example 1, the method comprises the following steps: S1. During the process of the circulating pump group 3 distributing the material to the drying device 1, part of the mother liquid enters the storage space 21 along the disturbance pipe 41 to disturb the mother liquid in the storage space 21.
[0067] During the operation of the drying equipment 1, the circulating pump group 3 runs accordingly, driving the mother liquor in the storage space 21 to be transported through the liquid outlet 22 along the distribution pipe 31 to distribute the material to the drying equipment 1. During this process, part of the mother liquor in the distribution pipe 31 can enter the bottom of the storage space 21 along the disturbance pipe 41 through the reflux port 23, thereby having a disturbance effect on the mother liquor in the storage space 21.
[0068] S2. After the material is placed on the drying device 1, the undried mother liquid flows by gravity into the storage space 21 to disturb the mother liquid in the storage space 21.
[0069] In the mother liquor of the fabric on the drying device 1, part of the mother liquor that has not dried will flow down from the drying device 1 under the action of its own gravity and fall back into the storage space 21. When the mother liquor falls back into the storage space 21, the impact on the original mother liquor in the storage space 21 also has a disturbing effect on it.
[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
