[0015] A working method of a high-efficiency crystallization menthol preparation device, and the specific operation steps of the method are as follows: Step 1: Place a single reaction bucket in the sunken groove I on the workbench I, inject the menthol raw solution into the reaction bucket through the feeding assembly on the workbench I, and then make the refrigeration assembly work to promote the menthol raw solution to generate solid menthol crystals. Step two, install the filter assembly on the reaction bucket in the sink head groove one, then take out the reaction bucket, pour waste liquid into the cavity two, then place the reaction bucket in the sink head groove two, and take off the used filter assembly; Step three, the telescopic end of the air cylinder pushes the lifting plate two to rise and fall quickly for several times, thereby pushing the extension plate and the reaction bucket to rise and fall for several times, and each time when the supporting ring falls to the upper surface of the sink head groove two, the reaction bucket and the peppermint crystal inside the reaction bucket will be vibrated, thereby making the peppermint crystal uniformly distributed in the reaction bucket; Step four, inject the ether solution into the reaction bucket containing the peppermint crystal, when the peppermint crystal is dissolved, install a new filter assembly on the reaction bucket again, then place the new reaction bucket in the sink head groove one on the workbench one, and then pour the ether and the peppermint in the reaction bucket on the workbench two into the reaction bucket on the workbench one; Step five, make the refrigeration assembly work to generate the peppermint crystal with high purity in the reaction bucket on the workbench one, then turn over the sealing assembly to open, and take out the reaction bucket on the workbench one together with the peppermint crystal.

[0016] The beneficial effects of the present application are as follows: 1. Place a single reaction vessel in the countersunk tank on workbench one. Then, inject menthol concentrate into the reaction vessel through the feeding assembly on workbench one. Next, invert the sealing assembly to seal the upper surface of the reaction vessel. Then, the cooling assembly in cavity one starts working, causing the menthol concentrate to form solid menthol crystals. Then, invert the sealing assembly to release the seal on the reaction vessel. The operator then installs the corresponding filter assembly for the reaction vessel and removes it from the countersunk tank one. Next, pour the waste liquid into cavity two on workbench two. The waste liquid is discharged through the discharge assembly. After the waste liquid in the reaction vessel is completely poured out, place the reaction vessel in the countersunk tank two. Then, remove the used filter assembly and inject ether solution into the reaction vessel through the feeding assembly on workbench two, causing the menthol crystals to dissolve in the ether solution. After dissolution, a new filter assembly is installed on the reaction vessel again. Then, a new reaction vessel is placed in the countersunk tank on workbench one. The ether and menthol in the reaction vessel on workbench two are then poured into the reaction vessel on workbench one. During this process, the filter assembly filters out impurities in the mixture. Then, the sealing assembly is flipped to seal and isolate the reaction vessel on workbench one. The cooling assembly is activated, causing the reaction vessel on workbench one to generate high-purity menthol crystals. The sealing assembly is then flipped open, and the reaction vessel on workbench one, along with the menthol crystals, is removed. A new reaction vessel is then placed in the countersunk tank on workbench one, and the above process is repeated to efficiently produce menthol. After a single batch of menthol is produced, the equipment does not need to be cleaned, thus reducing equipment downtime and allowing the equipment to operate continuously.

[0017] 2. When the reaction tank after emptying the waste liquid is placed in the sinker, the extension plate and handle are positioned by the positioning block. Then, the telescopic end of the cylinder extends and retracts rapidly several times, pushing the lifting plate two up and down rapidly several times, thereby pushing the extension plate and the reaction tank up and down several times. Each time the receiving ring falls onto the upper surface of the sinker, it will cause vibration of the reaction tank and the menthol crystals inside the reaction tank, preventing the menthol crystals from accumulating in one place in the reaction tank and affecting the subsequent dissolution rate in the ether solution.

[0018] 3. When it is necessary to load the reaction tank, the rotating column drives the extension arm and the spray head to rotate directly above the reaction tank. Through the cooperation of the liquid supply pump, liquid supply hose, spray head and spray nozzle, the required liquid is injected into the corresponding reaction tank. After the liquid injection is completed, the rotating column drives the extension arm and the spray head to rotate away from the reaction tank to avoid affecting the placement and removal of the reaction tank.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] Reference Figures 1-6 A highly efficient menthol crystallization preparation device includes a workbench 1, a workbench 2, and multiple reaction tanks 33. Workbench 1 has a cavity 3, and its upper surface has a countersunk groove 4 extending into the cavity 3. A cooling component (existing technology) is installed in the cavity 3. Workbench 2 has a cavity 5, and its upper surface has a countersunk groove 6 extending into the cavity 5. A discharge component is installed in the cavity 5. Both workbench 1 and workbench 2 have feeding components on their upper surfaces. Workbench 1 has a flip-sealing component. Each reaction tank 33 is detachably equipped with a filter component. Initially, the reaction tank 33 and the filter component are separate; the filter component is installed on the reaction tank 33 only when needed. A sufficient number of filter components are provided.

[0023] The feeding assembly on workbench 1 is used to feed menthol concentrate, and the feeding assembly on workbench 2 is used to feed ether solution.

[0024] In use, a single reaction vessel 33 is placed in the countersunk groove 4 on workbench 1. Then, menthol concentrate is injected into the reaction vessel 33 through the feeding assembly on workbench 1. The sealing assembly is then flipped to seal the upper surface of the reaction vessel 33. The cooling assembly in cavity 3 then operates, causing the menthol concentrate to form solid menthol crystals. The sealing assembly is then flipped to release the seal on the reaction vessel 33. The corresponding filter assembly is then installed on the reaction vessel 33. The reaction vessel 33 is then removed from the countersunk groove 4, and waste liquid is poured into cavity 5 on workbench 2. The waste liquid is discharged through the discharge assembly. After the waste liquid in the reaction vessel 33 has been poured out, it is placed in the countersunk groove 6. The used filter assembly is then removed, and ether solution is injected into the reaction vessel 33 through the feeding assembly on workbench 2. This causes the menthol crystals to dissolve in the ether solution. After the crystals have dissolved, a new filter assembly is installed on the reaction vessel 33 again. Then, a new reaction vessel 33 is placed in the countersunk groove 4 on workbench 1. The ether and menthol in the reaction vessel 33 on workbench 2 are then poured into the reaction vessel 33 on workbench 1. During this process, the filter assembly filters out impurities in the mixture. Then, the sealing assembly is flipped to seal the reaction vessel 33 on workbench 1. The cooling assembly is activated to generate high-purity menthol crystals in the reaction vessel 33 on workbench 1. The sealing assembly is then flipped open, and the reaction vessel 33 on workbench 1, along with the menthol crystals, is removed. A new reaction vessel 33 is then placed in the countersunk groove 4 on workbench 1, and the above process is repeated to efficiently produce menthol. After a single batch of menthol is produced, the equipment does not need to be cleaned, thus reducing equipment downtime and allowing the equipment to operate continuously.

[0025] Each reaction vessel 33 is fixedly fitted with a receiving ring 7 on its outer surface, and two extension plates 8 are also symmetrically fixed on the outer surface of each reaction vessel 33. Each extension plate 8 has a handle 9 fixed on its upper end face.

[0026] The set receiving ring 7 enables the reaction tank 33 to be inserted into the countersunk groove 4 or the countersunk groove 6. The set extension plate 8 and handle 9 make it convenient for staff to pick up and move the reaction tank 33.

[0027] Each filter assembly includes a mounting ring 10, and a filter layer 11 is fixed on the inner wall of each mounting ring 10. The mounting ring 10 is threaded onto the upper outer surface of the reaction vessel 33.

[0028] The filtering and blocking effects are achieved by setting the filter layer 11.

[0029] Each feeding assembly includes a rotating column 12, with an extension arm 13 fixedly fitted on the outer surface of the rotating column 12. A spray head 14 is fixed to the end of the extension arm 13. Multiple spray nozzles 15 are connected to the lower end face of the spray head 14, and a supply hose 16 is connected to the upper end face of the spray head 14. The other end of the supply hose 16 is connected to an external supply pump. One supply pump is connected to a supply tank containing menthol concentrate, and the other supply pump is connected to a supply tank containing ether solution.

[0030] One rotating column 12 is rotatably disposed through the upper end face of the worktable 1, and the other rotating column 12 is rotatably disposed through the upper end face of the worktable 1, thereby realizing the rotation of the rotating column 12, which is a conventional technical means in this field.

[0031] When it is necessary to feed the reaction tank 33, the rotating column 12 drives the extension arm 13 and the spray head 14 to rotate to directly above the reaction tank 33. Through the cooperation of the liquid supply pump, liquid supply hose 16, spray head 14 and spray nozzle 15, the required liquid is injected into the corresponding reaction tank 33. After the liquid injection is completed, the rotating column 12 drives the extension arm 13 and the spray head 14 to rotate away from the reaction tank 33 to avoid affecting the placement and removal of the reaction tank 33.

[0032] Each extension arm 13 has multiple clips 17 fixed to its upper end face.

[0033] The liquid supply hose 16 is limited by the set buckle 17.

[0034] The flip sealing assembly includes a U-shaped seat 18 movably mounted above the workbench 1, a rotating arm 19 rotatably mounted on the inner wall of the U-shaped seat 18, a sealing cover 20 fixed to the end of the rotating arm 19, and a motor 21 for use with the rotating arm 19 mounted on one side of the U-shaped seat 18.

[0035] When cooling the reaction vessel 33 placed in the workbench 1, the motor 21 drives the rotating arm 19 and the sealing cover 20 to rotate, causing the sealing cover 20 to cover the upper surface of the reaction vessel 33, thus cooperating to cool the reaction vessel 33.

[0036] The upper surface of the workbench 1 is provided with a recessed groove 22. A hydraulic rod 23 is fixed to the bottom of the recessed groove 22. A lifting plate 24 is fixed to the upper surface of the hydraulic rod 23. The lower surface of the U-shaped seat 18 is fixedly connected to the upper surface of the lifting plate 24.

[0037] When the reaction tank 33 is removed from the workbench 1, the telescopic end of the hydraulic rod 23 retracts, causing the lifting plate 24 and the U-shaped seat 18 to move downwards, so that the sealing cover 20 can cover the upper surface of the countersunk groove 4, reducing the loss of cold air.

[0038] The upper surface of the workbench 2 has two symmetrically arranged recessed grooves 25. A cylinder 26 is fixed to the bottom of the inner side of each recessed groove 25. A lifting plate 27 is fixed to the end of the telescopic end of the cylinder 26. Two positioning blocks 28 are fixed to the upper surface of the lifting plate 27. A guide block 29 is fixed to the inner wall of each recessed groove 25. Two guide posts 30 are fixed to the lower surface of the lifting plate 27. Each guide post 30 is movably inserted into the guide block 29.

[0039] When the waste liquid is poured out, the reaction tank 33 is placed into the countersink 6. The positioning block 28 positions the extension plate 8 and the handle 9. Then, the telescopic end of the cylinder 26 extends and retracts rapidly several times, pushing the lifting plate 27 to rise and fall rapidly several times. This causes the extension plate 8 and the reaction tank 33 to rise and fall several times. Each time the receiving ring 7 falls onto the upper surface of the countersink 6, it causes vibration of the reaction tank 33 and the menthol crystals inside the reaction tank 33. This prevents the menthol crystals from accumulating in one place in the reaction tank 33, which would affect the subsequent dissolution rate in the ether solution.

[0040] The discharge assembly includes a discharge collection hood 31 fixed in the cavity 2 5. The lower end of the discharge collection hood 31 is connected to a drain pipe 32, which is connected to an external waste liquid treatment tank.

[0041] After the waste liquid is poured into the sinker 6, it will drip into the discharge collection hood 31 and then be discharged through the discharge pipe 32.

[0042] A method for operating a highly efficient menthol crystallization preparation device, the specific operating steps of which are as follows:

[0043] Step 1: Place a single reaction vessel 33 into the countersunk groove 4 on the workbench 1. Inject menthol stock solution into the reaction vessel 33 through the feeding component on the workbench 1. Then, the cooling component works to cause the menthol stock solution to produce solid menthol crystals. Step 2: Install the filter assembly on the reaction tank 33 in the countersunk tank 4, then remove the reaction tank 33, pour the waste liquid into the cavity 5, then place the reaction tank 33 in the countersunk tank 6, and remove the used filter assembly. Step 3: The telescopic end of cylinder 26 pushes the lifting plate 27 to rise and fall rapidly several times, thereby pushing the extension plate 8 and the reaction tank 33 to rise and fall several times. Each time the receiving ring 7 falls onto the upper surface of the countersunk groove 26, it will cause the reaction tank 33 and the menthol crystals inside the reaction tank 33 to vibrate, thereby making the menthol crystals evenly distributed inside the reaction tank 33. Step 4: Inject ether solution into reaction vessel 33 containing menthol crystals. After the menthol crystals have dissolved, install a new filter assembly on reaction vessel 33 again. Then, place a new reaction vessel 33 in countersunk groove 4 on workbench 1. Then, pour the ether and menthol in reaction vessel 33 on workbench 2 into reaction vessel 33 on workbench 1. Step 5: The cooling component operates, causing high-purity menthol crystals to form in the reaction vessel 33 on workbench 1. Then, the sealing component is flipped open, and the reaction vessel 33 on workbench 1, along with the menthol crystals, is removed.

[0044] In use, a single reaction vessel 33 is placed in the countersunk groove 4 on workbench 1. Then, menthol concentrate is injected into the reaction vessel 33 through the feeding assembly on workbench 1. The sealing assembly is then flipped to seal the upper surface of the reaction vessel 33. The cooling assembly in cavity 3 then operates, causing the menthol concentrate to form solid menthol crystals. The sealing assembly is then flipped to release the seal on the reaction vessel 33. The corresponding filter assembly is then installed on the reaction vessel 33. The reaction vessel 33 is then removed from the countersunk groove 4, and waste liquid is poured into cavity 5 on workbench 2. The waste liquid is discharged through the discharge assembly. After the waste liquid in the reaction vessel 33 has been poured out, the reaction vessel 33 is placed in the countersunk groove 6. The used filter assembly is then removed, and ether solution is injected into the reaction vessel 33 through the feeding assembly on workbench 2. This causes the menthol crystals to dissolve in the ether solution. After the menthol crystals have dissolved, a new filter assembly is installed on the reaction vessel 33 again. Then, a new reaction vessel 33 is placed in the countersunk groove 4 on workbench 1. The ether and menthol in the reaction vessel 33 on workbench 2 are then poured into the reaction vessel 33 on workbench 1. During this process, the filter assembly filters out impurities in the mixture. Then, the sealing assembly is flipped to seal the reaction vessel 33 on workbench 1. The cooling assembly is activated to generate high-purity menthol crystals in the reaction vessel 33 on workbench 1. The sealing assembly is then flipped open, and the reaction vessel 33 on workbench 1, along with the menthol crystals, is removed. A new reaction vessel 33 is then placed in the countersunk groove 4 on workbench 1. The above process is repeated to efficiently produce menthol. After a single batch of menthol is produced, the equipment does not need to be cleaned, thus reducing equipment downtime and allowing the equipment to operate continuously. When the waste liquid is poured out, the reaction tank 33 is placed into the countersink 6. The positioning block 28 positions the extension plate 8 and the handle 9. Then, the telescopic end of the cylinder 26 extends and retracts rapidly several times, pushing the lifting plate 27 to rise and fall rapidly several times. This causes the extension plate 8 and the reaction tank 33 to rise and fall several times. Each time the receiving ring 7 falls onto the upper surface of the countersink 6, it causes vibration of the reaction tank 33 and the menthol crystals inside the reaction tank 33. This prevents the menthol crystals from accumulating in one place in the reaction tank 33, which would affect the subsequent dissolution rate in the ether solution.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
