Description

Technical Field

[0001] The utility model relates to the technical field of flavor and fragrance processing, and more specifically to a water separation device for producing and processing salicylaldehyde. Background Art

[0002] Salicylaldehyde is a colorless, clear, oily liquid with a burnt and almond smell. It is slightly soluble in water and soluble in organic solvents such as ether. Salicylaldehyde is also a fragrance and a widely used organic synthesis intermediate. It is obtained by the reaction of phenol and chloroform in sodium hydroxide solution. It is often used in the synthesis of salicylamide, benzbromarone and acetaminophen in drug synthesis. In the processing of salicylaldehyde, in order to remove the water produced in the reaction and promote the forward progress of the organic reaction, various water separators are mainly used for removal.

[0003] Chinese patent authorization announcement number: CN212833683U discloses a water separation device for the production and processing of salicylaldehyde. In this scheme, the material applies pressure to the movable plate, the movable plate moves downward under the force, and compresses the return spring, the slot inside the sealing plate leaks out, and the material passes through the slot and flows through the next pipe. Under the dual action of the first hydrophilic permeable membrane and the second hydrophilic permeable membrane, the water separation effect of salicylaldehyde is improved.

[0004] In the above scheme, a hydrophilic permeable membrane is used to block the salicylaldehyde organic liquid in the mixed solution. However, when there are a large amount of impurities, particulate matter or suspended matter in the mixed solution, they may accumulate on the surface of the hydrophilic permeable membrane and block the membrane pores after working for a long time. At this time, the staff needs to stop the water separation operation of the mixed solution and remove the hydrophilic permeable membrane for cleaning. However, the hydrophilic permeable membrane needs to be installed again. The disassembly and assembly of the hydrophilic permeable membrane takes a certain amount of time, resulting in excessive equipment downtime and reduced water separation efficiency. Therefore, in view of the above problems, a water separation device for the production and processing of salicylaldehyde is proposed. Utility Model Content

[0027] Example:

[0028] See also Figure 1-3A water separation device for production and processing of salicylaldehyde, comprising an air inlet pipe 1, a main pipe 5 and a pair of separation components 4, a condenser pipe 2 is installed on the air inlet pipe 1, and an upper separation pipe 3 is fixedly connected to one end of the air inlet pipe 1, a lower separation pipe 6 connected to the upper separation pipe 3 is fixedly connected to the outer end of the upper separation pipe 3, and a discharge pipe 7 connected to the lower separation pipe 6 is fixedly connected to the outer end of the lower separation pipe 6, and the upper separation pipe 3 and the main pipe 5 and the lower separation pipe 6 and the main pipe 5 are connected through the separation component 4;

[0029] The separation assembly 4 includes a first connection block 41 and a second connection block 42. The first connection block 41 is provided with a pair of communication holes 49. The second connection block 42 is provided with a plurality of permeation holes 43. The permeation holes 43 are each provided with a matching hydrophilic permeable membrane 45.

[0030] Salicylaldehyde is also a fragrance and a widely used organic synthesis intermediate. It is obtained by the reaction of phenol and chloroform in a sodium hydroxide solution. This scheme is used to remove the water produced during the processing of salicylaldehyde and promote the forward progress of the organic reaction.

[0031] Specifically, the mixed steam generated by the reaction enters the air inlet pipe 1 and is cooled into a mixed liquid by the condenser 2, and enters the interior of the upper separation pipe 3. The water inside is discharged into the main pipe 5 under the separation effect of the hydrophilic permeable membrane 45 in the separation component 4, and then discharged from the main pipe 5 to the outside for recovery. However, the salicylaldehyde organic liquid in the mixed solution will be retained by the hydrophilic permeable membrane 45, and the retained salicylaldehyde organic liquid and a part of the mixed solution are discharged into the lower separation pipe 6. The water in the material passes through another hydrophilic permeable membrane 45, enters the main pipe 5 and is discharged to the outside. The material accumulated at the right end of the lower separation pipe 6 is finally discharged to the outside through the discharge pipe 7.

[0032] Among them, a shielding component is provided in the lower separation tube 6 and the discharge pipe 7. The shielding component can be a spring baffle. When the salicylaldehyde organic liquid in the upper separation tube 3 and the lower separation tube 6 reaches a certain weight, the spring baffle is opened. In addition, a condenser 2 can be installed on the lower separation tube 6 to perform secondary condensation on the mixed steam entering the lower separation tube 6.

[0033] See also Figure 2-3 The first connecting block 41 is rotatably connected to the second connecting block 42 , and a pair of handles 48 are fixedly connected to the outer end of the first connecting block 41 .

[0034] In this embodiment, the upper separation tube 3 and the main tube 5 are connected through the separation assembly 4, wherein the first connection block 41 is rotatably connected to the upper separation tube 3, and a pair of communication holes 49 on the first connection block 41 are connected to the upper separation tube 3, the second connection block 42 is fixedly connected to the main tube 5, and the multiple penetration holes 43 on the second connection block 42 are all connected to the main tube 5, and the mixed solution in the upper separation tube 3 is discharged through the communication holes 49. Since the positions of the communication holes 49 and the penetration holes 43 correspond, the mixed solution enters the penetration holes 43 at this time, and the water in the mixed solution passes through the hydrophilic permeable membrane 45 and is discharged into the main tube 5, while the salicylaldehyde organic liquid is retained;

[0035] The lower separation tube 6 and the main tube 5 are also connected through the separation assembly 4, wherein the first connection block 41 is rotatably connected to the lower separation tube 6, and a pair of connecting holes 49 on the first connection block 41 are connected to the lower separation tube 6, and the second connection block 42 is fixedly connected to the main tube 5, and the multiple penetration holes 43 on the second connection block 42 are all connected to the main tube 5.

[0036] Specifically, when one of the pairs of hydrophilic permeable membranes 45 is blocked, the staff can control the first connecting block 41 to rotate 90 degrees, so that the first connecting block 41 and the second connecting block 42 rotate relative to each other, and open a pair of connecting holes 49 at the outer end of the first connecting block 41 to correspond to the other pair of permeable holes 43. At this time, the pair of hydrophilic permeable membranes 45 can immediately perform water diversion operations, reducing the downtime of the equipment, ensuring the continuity of the water diversion process, and improving the water diversion efficiency.

[0037] See also Figure 2 A retaining ring 44 is fixedly connected to the inner wall of the penetration hole 43, a first magnet is installed at one end of the retaining ring 44 close to the hydrophilic permeable membrane 45, and a second magnet attracted to the first magnet is installed at one end of the hydrophilic permeable membrane 45 close to the retaining ring 44.

[0038] In this embodiment, the hydrophilic permeable membrane 45 is fixed into the permeable hole 43 by the cooperation between the first magnet and the second magnet.

[0039] Please continue reading Figure 2 A pair of reserved holes 46 are provided on the first connecting block 41. The pair of reserved holes 46 and the pair of connecting holes 49 correspond to the multiple penetration holes 43 one by one. The interiors of the pair of reserved holes 46 are threadedly connected with sealing plugs 47. The outer end of the hydrophilic permeable membrane 45 is integrally formed with a U-shaped pull rod to facilitate the removal of the hydrophilic permeable membrane 45.

[0040] In this embodiment, the staff can remove the sealing plug 47 and take out the blocked hydrophilic permeable membrane 45 from the permeable hole 43 through the reserved hole 46 for cleaning, thereby ensuring the continuous water separation process.

[0041] See also Figure 3 A pair of sealing gaskets are fixedly connected to one end of the first connecting block 41 close to the second connecting block 42 , and the pair of sealing gaskets are both in contact with the second connecting block 42 , and the positions of the pair of sealing gaskets correspond to the positions of the pair of communicating holes 49 .

[0042] In this embodiment, a pair of sealing gaskets are provided to improve the sealing performance between the communication hole 49 and the permeation hole 43 and reduce the probability of solution outflow.

[0043] Working principle: The mixed steam generated by the reaction enters the air inlet pipe 1 and is cooled into a mixed liquid by the condenser 2, and then enters the upper separation pipe 3. The water inside is discharged into the main pipe 5 under the separation effect of the hydrophilic permeable membrane 45 in the separation component 4, and then discharged from the main pipe 5 to the outside for recovery. However, the salicylaldehyde organic liquid in the mixed solution will be retained by the hydrophilic permeable membrane 45, and the retained salicylaldehyde organic liquid and a part of the mixed solution are discharged into the lower separation pipe 6. The water in the material passes through another hydrophilic permeable membrane 45 into the main pipe 5 and is discharged to the outside. The material accumulated at the right end of the lower separation pipe 6 is finally discharged through the discharge pipe 7. When a pair of hydrophilic permeable membranes 45 are blocked, the staff can control the first connecting block 41 to rotate 90 degrees, so that the first connecting block 41 and the second connecting block 42 rotate relative to each other, and a pair of connecting holes 49 are opened at the outer end of the first connecting block 41 to correspond to the other pair of permeation holes 43. At this time, the pair of hydrophilic permeable membranes 45 can immediately perform water diversion operations, thereby reducing the downtime of the equipment and improving the water diversion efficiency. In addition, the staff can remove the sealing plug 47 and take out the blocked hydrophilic permeable membrane 45 from the permeation hole 43 through the reserved hole 46 for cleaning, thereby ensuring the continuous progress of the water diversion process.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
