[0002] Adenosylmethionine butadisulfonate can be used to treat hepatobiliary diseases and has multiple mechanisms of action and pharmacological effects. First, it can improve the fluidity of liver cell membranes, enhance the activity of corresponding enzymes, promote the secretion and circulation of bile, and also participate in the synthesis of neurotransmitters, so it can improve the patient's mood to a certain extent. In addition, as an endogenous detoxifier, this drug can detoxify some toxic substances and reduce the damage of toxic substances to the liver. It has high practical value, and adenosylmethionine butadisulfonate salt is an indispensable component in the preparation process of adenosylmethionine butadisulfonate.

[0003] At present, the preparation method of adenosylmethionine butane disulfonate is mainly to introduce the prepared stock solution into the electrodialyzer for concentration, and then transport it to the evaporation crystallizer for salt production. Due to the height difference between the evaporation crystallizer and the electrodialyzer, the transportation pipelines need to be connected in the form of elbows to facilitate the laying of the pipelines. However, since there are many crystals in the concentrated solution, it is easy for the crystal components in the concentrated solution to contact the inner wall of the elbow when it is transported to the elbow, resulting in excessive solute density, resulting in crystal precipitation and blockage. Therefore, technical personnel in the field have proposed an electrodialysis salt-forming device for preparing adenosylmethionine butane disulfonate to solve the above problems.

[0038] Wherein, the connecting structure 4 includes a curved pipe 401, both ends of which are provided with liquid passage cavities, one end of the curved pipe 401 is provided with a connecting pipe 402, a flow cavity 404 is provided inside the curved pipe 401, a slide groove 406 is provided on the inner wall of the flow cavity 404, and transition cavities 405 are provided at both end openings of the flow cavity 404, the opening cross-section of the transition cavity 405 is conical, the flow cavity 404 is connected with the adjacent liquid passage cavity through the transition cavity 405, the maximum opening diameter of the transition cavity 405 is equal to the inner diameter of the concentrated brine outlet pipe 102, the minimum opening diameter of the transition cavity 405 is equal to the inner diameter of the flow cavity 404, and a cleaning component 41 is provided inside the curved pipe 401.

[0039] Under the combined action of the ion exchange membrane and the DC electric field inside the electrodialyzer 1, the electrolyte ions in the stock solution are selectively migrated, so that the stock solution is divided into concentrated brine and fresh water after electrodialysis, wherein the concentrated brine can be introduced into the interior of the liquid inlet pipe 201 through the concentrated brine outlet pipe 102 under the action of the pump body 2, and then introduced into the interior of the evaporation crystallizer 3 through the liquid inlet pipe 201, and the effect of precipitating adenosyl methionine disulfonate is achieved through the evaporation crystallizer 3, wherein the pump body 2 is a corrosion-resistant centrifugal pump, which can effectively transport the concentrated brine;

[0040] The connection structure 4 can divide the brine outlet pipe 102 and the liquid inlet pipe 201 into multiple sections and is used to connect the bends thereof, so as to adapt to the height difference between the electrodialyzer 1, the pump body 2 and the evaporation crystallizer 3, and facilitate the pipeline laying of the entire device;

[0041] The following description is made by taking the connection structure 4 provided on the concentrated brine outlet pipe 102 as an example;

[0042] The liquid passage chambers at both ends of the curved pipe 401 are respectively connected to two sections of concentrated brine outlet pipes 102. When concentrated brine is introduced into the liquid passage chamber through one section of the concentrated brine outlet pipe 102, it can be guided into the interior of the flow chamber 404 under the action of the transition chamber 405. Since the maximum opening diameter of the transition chamber 405 is equal to the inner diameter of the concentrated brine outlet pipe 102, and the minimum opening diameter of the transition chamber 405 is equal to the inner diameter of the flow chamber 404, the inner diameter of the flow chamber 404 is smaller than the inner diameter of the concentrated brine outlet pipe 102, so that the flow velocity at the bend is faster, reducing the crystal components in the concentrated brine and After contacting the inner wall of the traditional curved pipe 401, it is easy to deposit, resulting in excessive solute density, resulting in crystal precipitation and blockage. After passing through the flow cavity 404, it is introduced into the connecting pipe 402 through the liquid cavity at the other end and discharged into the interior of another section of the concentrated brine outlet pipe 102. One end of the curved pipe 401 and the connection between the connecting pipe 402 and the concentrated brine outlet pipe 102 can be connected by a flange, and sealed in the form of a sealing ring. The use of the flange and the sealing ring in coordination with each other is a technical means well known to technicians in this field, so it is not shown in the figure and will not be excessively described here.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one end of the connecting tube 402 is fixedly connected to the mounting shell 403, and the other end of the mounting shell 403 is connected to one end of the bent tube 401. The inner wall of the mounting shell 403 is rotatably connected to the gear ring 407, and the surface of the mounting shell 403 is fixedly connected to the connecting block 415. The interior of the connecting block 415 is rotatably connected to the gear 416 meshing with the gear ring 407, and the axis of the gear 416 is fixedly connected to the mounting rod 409.

[0044] The surface of the connecting tube 402 is fixedly connected to a mounting block 410, the surface of the mounting block 410 is provided with a driving groove connected to the connecting tube 402, the inner wall of the driving groove is rotatably connected to a rotating shaft 411, the surface of the rotating shaft 411 is fixedly connected to a ring-shaped driving blade 412, and the driving blade 412 extends to the interior of the connecting tube 402.

[0045] The inner wall of the mounting block 410 is rotatably connected to a rotating rod, a second cone wheel 417 is fixedly connected to the surface of the rotating rod, a transmission structure 413 is provided at one end of the rotating rod, and one end of the rotating shaft 411 passes through a driving groove and is fixedly connected to the other end of the transmission structure 413.

[0046] The other end of the mounting rod 409 passes through the connecting block 415 and the mounting block 410 in sequence and is fixedly connected to the first cone wheel 414 . The first cone wheel 414 is meshedly connected to the second cone wheel 417 .

[0047] The inner diameter of the gear ring 407 is equal to the inner diameter of the connecting pipe 402, and a connecting rod 408 is fixedly connected to the inner side of the gear ring 407;

[0048] In the process that the concentrated brine passes through the curved pipe 401 and is introduced into the concentrated brine outlet pipe 102 at the other end through the connecting pipe 402, the driving blade 412 can be pushed to make the rotating shaft 411 rotate, and the rotating rod connected thereto is driven to rotate through the transmission structure 413 under the rotation action of the rotating shaft 411, wherein the transmission structure 413 is composed of two transmission wheels and a transmission belt, by driving one of the transmission wheels to rotate, the other transmission wheel can be driven to rotate synchronously under the action of the transmission belt, and this technical means is a technical means well known to those skilled in the art and will not be elaborated on here. In the process that the rotating rod rotates, the second cone wheel 417 can be driven to rotate synchronously, which can drive the first cone wheel 414 to rotate, thereby driving the mounting rod 409 to rotate the gear 416 under the action of the first cone wheel 414, which can drive the gear ring 407 to rotate under the meshing action of the gear 416 and the gear ring 407 to achieve the effect of rotating the connecting rod 408.

[0049] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the cleaning component 41 includes a swivel 4102 rotatably connected to the inner wall of the liquid cavity at one end away from the bend pipe 401 and away from the connecting pipe 402, the inner wall of the swivel 4102 is fixedly connected with a connecting shell 4105, a storage cavity is opened inside the connecting shell 4105, the inner wall of the storage cavity is rotatably connected with a winding rod 4107, the surface of the winding rod 4107 is wound with an expansion rope 4108, one end of the winding rod 4107 passes through the storage cavity and is rotatably connected to the inner wall of the connecting shell 4105, the surface of the winding rod 4107 is fixedly connected with a spring 4106, and the other end of the spring 4106 is fixedly connected to the inner wall of the connecting shell 4105.

[0050] The cleaning assembly 41 also includes a slider 4103 slidably connected to the inner wall of the slide groove 406, and a through hole is opened on the surface of the slider 4103. A connecting rope 4101 is arranged inside the through hole. One end of the connecting rope 4101 is fixedly connected to the unwinding end of the expansion rope 4108, and the other end of the connecting rope 4101 is fixedly connected to one end of the connecting rod 408.

[0051] The connecting rope 4101 and the expansion rope 4108 are both made of PE material, and the surface of the connecting rope 4101 is fixedly connected with evenly distributed cleaning brushes 4104;

[0052] During the rotation of the connecting rod 408, the connecting rope 4101 can be driven to rotate synchronously. During this process, the cleaning brush 4104 arranged on the surface of the connecting rope 4101 can be driven to clean the inside of the flow chamber 404, thereby further reducing the blockage caused by crystal accumulation inside the flow chamber 404. At the same time, since the blockage caused by crystal accumulation is reduced, the crystals in the concentrated brine can be well transported to the inside of the evaporation crystallizer 3, thereby improving the salt precipitation rate. In addition, by providing the connecting shell 4105 and the rotating ring 4102, the connecting shell 4105 can be driven to rotate along the inner wall of the liquid passage chamber through the rotating ring 4102 during the rotation of the connecting rope 4101, and the mutual cooperation of the slide groove 406 and the slider 4103 can ensure that the connecting rope 4101 It can slide along the inner wall of the flow chamber 404. During this process, due to the bending of the curved tube 401, the area of ​​the outer side of the flow chamber 404 is larger than the area of ​​the inner side. Therefore, during the movement of the connecting rope 4101, the expansion rope 4108 can be pulled out from the inside of the connecting shell 4105, and the expansion rope 4108 can be unwound to ensure that the connecting rope 4101 can drive the cleaning brush 4104 to always contact with the inner wall of the flow chamber 404. The setting of the spring 4106 can tighten the expansion rope 4108, thereby ensuring that the expansion rope 4108 is tightened during the movement of the connecting rope 4101 from the outer side to the inner side of the flow chamber 404, so that the connecting rope 4101 always drives the cleaning brush 4104 to contact with the inner wall of the flow chamber 404, thereby improving the cleaning effect.

[0053] like Figure 1 and Figure 7 As shown, the surface of the liquid inlet pipe 201 close to one end of the evaporation crystallizer 3 is fixedly connected with evenly distributed heat dissipation blades 302, and the condenser pipe 301 passes through the heat dissipation blades 302 in a spiral shape;

[0054] The end of the liquid inlet pipe 201 close to the evaporation crystallizer 3 will transfer heat to the surface of the liquid inlet pipe 201 during the use of the evaporation crystallizer 3, resulting in the blockage of the inner wall crystals when the concentrated brine is subsequently transported, affecting the subsequent transportation and the precipitation rate of adenosyl methionine butanedisulfonate. The condenser pipe 301 is used to transport the cooling liquid required during the use of the evaporation crystallizer 3. The condenser pipe 301 passes through the heat dissipation blade 302 in a spiral shape, and the heat dissipation blade 302 can be used to dissipate the heat of the liquid inlet pipe 201, so as to avoid affecting the subsequent transportation of the concentrated brine.

[0055] Working principle: Under the combined action of the ion exchange membrane and the DC electric field inside the electrodialyzer 1, the electrolyte ions in the stock solution are selectively migrated, so that the stock solution is divided into concentrated brine and fresh water after electrodialysis, wherein the concentrated brine can be introduced into the interior of the liquid inlet pipe 201 through the concentrated brine outlet pipe 102 under the action of the pump body 2, and then introduced into the interior of the evaporation crystallizer 3 through the liquid inlet pipe 201, and the effect of precipitating adenosyl methionine disulfonate is achieved through the evaporation crystallizer 3. Under the action of the connecting structure 4, the concentrated brine can be introduced into the interior of the liquid inlet pipe 201 through the concentrated brine outlet pipe 102 under the action of the pump body 2, and then introduced into the interior of the evaporation crystallizer 3 through the liquid inlet pipe 201. The brine outlet pipe 102 and the liquid inlet pipe 201 are divided into multiple sections and are used to connect their bends to adapt to the height difference between the electrodialyzer 1, the pump body 2 and the evaporation crystallizer 3, which is convenient for the overall pipeline laying of the device. In addition, the inner diameter of the flow cavity 404 is smaller than the inner diameter of the concentrated brine outlet pipe 102, so that the flow velocity at the bend is faster, and the crystal components in the concentrated brine are easily deposited after contacting the inner wall of the traditional curved pipe 401, resulting in excessive solute density, resulting in crystal precipitation and blockage. After passing through the flow cavity 404, it passes through another The liquid passage cavity at one end is introduced into the connecting pipe 402 and discharged into the interior of the other section of the concentrated brine outlet pipe 102. In the process that the concentrated brine passes through the curved pipe 401 and is introduced into the interior of the concentrated brine outlet pipe 102 at the other end through the connecting pipe 402, the driving blade 412 can be pushed to rotate the rotating shaft 411, and the rotating rod connected thereto is driven to rotate through the transmission structure 413 under the rotation action of the rotating shaft 411, and the first cone wheel 414, the second cone wheel 417, the mounting rod 409 and the gear 416 cooperate with each other to drive the gear ring 407 to rotate the connecting rod 408. By setting the cleaning component 41, the connecting rope 4101 can be driven to rotate synchronously during the rotation of the connecting rod 408. In this process, the cleaning brush 4104 set on the surface of the connecting rope 4101 can be driven to clean the interior of the flow cavity 404, further reducing the blockage caused by crystal accumulation in the flow cavity 404. At the same time, due to the reduction of blockage caused by crystal accumulation, the crystals in the concentrated brine can be well transported to the interior of the evaporation crystallizer 3, thereby improving the salt precipitation rate.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
