Description

Technical Field

[0001] This utility model belongs to the field of menthol dehydration technology, specifically relating to a menthol grading and dehydration device. Background Technology

[0002] Menthol, extracted from peppermint, is used as an additive in the pharmaceutical and food industries. Crude menthol has a high water content and requires dehydration to remove excess water. Currently, menthol is dehydrated using a graded dehydration device. Due to the difference in volatilization temperatures between menthol and water, distillation is used to remove some water during dehydration. However, some liquid comes into contact with the top wall of the tank, condenses, and drips down, affecting the efficiency of distillation. A graded dehydration device for menthol, proposed in application number 202420583371.6, uses an arc-shaped scraper and a drainage groove to scrape the water from the tank. The solution addresses the issue of condensate on the top wall, which is collected by an annular inclined flow channel and collection pipe after scraping. This solves the problem of dripping after steam condensation. However, the continuous direct contact and friction between the arc-shaped scraper and the top wall of the tank inevitably damages the paint and coating on the surface of the top wall. This not only affects the service life of the tank but also allows fine particles from wear to enter and mix into the menthol, affecting the quality of the finished product. In particular, when the inner metal of the tank is exposed or the arc-shaped scraper is made of metal, the metal particles from wear can cause heavy metal contamination in the menthol product, rendering it unusable. Utility Model Content

[0003] This invention provides a menthol grading and dehydration device that can effectively reduce the wear of the heat-insulating coating cone sleeve and the impact of friction-generated microparticles on the quality of the finished liquid.

[0004] This utility model provides the following technical solution: a menthol grading and dehydration device, comprising a menthol grading and dehydration tank body, a drive rod, a stirring rod, a collection pipe, and a collection tank. A heat-insulating coated conical sleeve is fixedly connected inside the menthol grading and dehydration tank body. A connecting strip is provided inside the heat-insulating coated conical sleeve. A fine hydrophilic water droplet brush is fixedly connected to the top of the connecting strip. A distance is left between the fine hydrophilic water droplet brush and the heat-insulating coated conical sleeve. A diversion groove plate is detachably connected to the bottom of the connecting strip. A positioning rod is inserted into the diversion groove plate.

[0005] The stirring rod has a locking sleeve fixedly connected to its top end, and the locking sleeve is detachably connected to the drive rod.

[0006] An extension plate is fixedly connected to the bottom end of the drainage channel plate, and the extension plate extends into the collection channel.

[0007] The bottom end of the diversion channel plate is fixedly connected to a support rod, and the bottom end of the support rod is fixedly connected to a connecting sleeve, which is sleeved on the outer wall of the drive rod.

[0008] The bottom end of the drainage channel plate is fixedly connected to a positioning sleeve, and the positioning rod is detachably connected to the positioning sleeve.

[0009] The positioning rod has a reference scale on its outer wall.

[0010] A protective pad is fixedly connected to one end of the positioning rod near the heat-insulating coating cone sleeve.

[0011] The beneficial effects of this utility model are as follows: By accurately positioning the connecting strip with the positioning rod, the connecting strip can be installed in a position close to but not in contact with the heat-insulating coating cone sleeve. With the continuous driving of the connecting strip, the fine hydrophilic water droplet brush, and the drainage groove plate by the driving rod, the surface tension of the droplets can be broken by the connecting strip. Combined with the hydrophobicity of the inner coating of the heat-insulating coating cone sleeve and the hydrophilicity of the connecting strip, the droplets can be drawn to the fine hydrophilic water droplet brush and the drainage groove plate, cleaning the droplets gathered on the inner wall of the heat-insulating coating cone sleeve. This prevents the droplets from dripping back into the menthol grading dehydration tank and affecting the dehydration efficiency. Furthermore, it does not directly contact the inner wall of the heat-insulating coating cone sleeve, effectively reducing the wear of the heat-insulating coating cone sleeve and the impact of friction-generated microparticles on the quality of the finished liquid.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0015] Please see Figures 1-4The present invention provides the following technical solution: a menthol grading and dehydration device, comprising a menthol grading and dehydration tank body 1, a drive rod 11, a stirring rod 12, a collection pipe 13 and a collection trough 14, wherein a heat-insulating coated cone sleeve 2 is fixedly connected inside the menthol grading and dehydration tank body 1, and a connecting strip 3 is provided inside the heat-insulating coated cone sleeve 2. A fine hydrophilic water drop brush 31 is fixedly connected to the top of the connecting strip 3, and a distance is left between the fine hydrophilic water drop brush 31 and the heat-insulating coated cone sleeve 2. A diversion groove plate 32 is detachably connected to the bottom of the connecting strip 3, and a positioning rod 4 is inserted into the diversion groove plate 32.

[0016] In this implementation scheme: a hydrophobic coating is provided on the inner wall of the heat-insulating coating cone sleeve 2, and a hydrophilic coating is provided on the surface of the fine hydrophilic water droplet brush 31. During the menthol grading and dehydration stage, according to the existing component operation and usage process, during the menthol grading, dehydration, and distillation process of the menthol grading and dehydration tank body 1, the original liquid is added to the menthol grading and dehydration tank body 1, heated and distilled, and discharged through the collection pipe 13. Some of the vapors are cooled and adhere to the inner wall of the heat-insulating coating cone sleeve 2, and condense into water droplets. Under the action of the surface tension of the droplets, larger droplets will continue to condense before they reach a certain volume, and will not drip directly. The drive rod 11 rotates continuously under the action of the drive motor. The drive rod 11 drives the connecting bar 3, the fine hydrophilic droplet brush 31, and the drainage groove plate 32 to rotate continuously. The fine hydrophilic droplet brush 31 will come into contact with the droplets in the convergence state. When the fine hydrophilic droplet brush 31 comes into contact with the droplets, it will disrupt the surface tension of the droplets. Under the influence of the hydrophobicity of the inner surface coating of the heat insulation coating cone sleeve 2, the hydrophilicity of the fine hydrophilic droplet brush 31, and the capillary action generated between the bristles of the fine hydrophilic droplet brush 31, the droplets will flow into the fine hydrophilic droplet brush 31 and the gaps between the bristles of the fine hydrophilic droplet brush 31. When the liquid volume increases, it will converge into the fine hydrophilic droplet brush 31 and the drainage groove plate 32, and then flow along the drainage groove plate 32. 2. The liquid flows into the collection tank 14 and converges in the collection pipe 13. The fine hydrophilic water droplet brush 31 is close to but does not contact the heat-insulating coating cone sleeve 2, which can prevent the droplets from dripping back into the menthol grading dehydration tank body 1 and affecting the dehydration efficiency. It also does not directly contact the inner wall of the heat-insulating coating cone sleeve 2, effectively reducing the wear of the heat-insulating coating cone sleeve 2 and the impact of friction-generated microparticles on the quality of the finished liquid. When installing the connecting strip 3, the positioning rod 4 is installed in the appropriate position by referring to the scale 41. The end of the positioning rod 4 protrudes from the appropriate position of the fine hydrophilic water droplet brush 31. Then, the positioning rod 4 is fastened to the side wall of the positioning sleeve 35 with a bolt threaded connection. The connecting strip 3 and the fine hydrophilic water droplet brush 31 are then connected. The hydrophilic water droplet brush 31 and the drainage channel plate 32 are pushed upwards as a whole until the positioning rod 4 contacts the inner wall of the heat insulation coating cone sleeve 2. Then, the connecting sleeve 34 is fixed to the outer wall of the drive rod 11 with bolts. At this time, the end of the fine hydrophilic water droplet brush 31 is close to the inner wall of the heat insulation coating cone sleeve 2 but with a gap. Then, the positioning rod 4 is removed from the drainage channel plate 32 to avoid the positioning rod 4 from continuously rubbing against the heat insulation coating cone sleeve 2. The connecting strip 3 and the drainage channel plate 32 are connected by bolts. The connecting strip 3 and the drainage channel plate 32 are provided with multiple threaded holes at corresponding positions. After the connecting strip 3 and the drainage channel plate 32 are aligned, the bolts are screwed into the bolt holes in the drainage channel plate 32 and the connecting strip 3 in sequence.

[0017] A locking sleeve 15 is fixedly connected to the top of the stirring rod 12, and the locking sleeve 15 is detachably connected to the drive rod 11. The locking sleeve 15 facilitates the connection between the stirring rod 12 and the drive rod 11. When the connecting strip 3 is disassembled, the stirring rod 12 is separated from the drive rod 11. After the connecting strip 3 is installed, the locking sleeve 15 is fitted onto the end of the drive rod 11, and then the locking sleeve 15 is fixed to the end of the drive rod 11 with bolts.

[0018] An extension plate 321 is fixedly connected to the bottom end of the diversion trough plate 32, and the extension plate 321 extends into the collection tank 14; by setting the extension plate 321, the diversion channel can be extended, and the liquid can be directly diverted into the collection tank 14.

[0019] A support rod 33 is fixedly connected to the bottom end of the diversion channel plate 32, and a connecting sleeve 34 is fixedly connected to the bottom end of the support rod 33. The connecting sleeve 34 is sleeved on the outer wall of the drive rod 11. The diversion channel plate 32 can be supported by the support rod 33 and the connecting sleeve 34. When installing the connecting strip 3, the connecting sleeve 34 is fixed to the outer wall of the drive rod 11 with bolts.

[0020] A positioning sleeve 35 is fixedly connected to the bottom end of the drainage channel plate 32, and the positioning rod 4 is detachably connected to the positioning sleeve 35; by setting the positioning sleeve 35 and the positioning rod 4 to be detachably connected, the positioning rod 4 can be positioned.

[0021] The outer wall of the positioning rod 4 is provided with a reference scale 41; by setting the reference scale 41, the installation position of the positioning rod 4 can be accurately referenced.

[0022] A protective pad 42 is fixedly connected to one end of the positioning rod 4 near the heat insulation coating cone sleeve 2; by setting the protective pad 42, the end of the positioning rod 4 can be prevented from squeezing the inner wall of the heat insulation coating cone sleeve 2, which would cause damage to the coating of the inner wall of the heat insulation coating cone sleeve 2.

[0023] The working principle and usage process of this utility model: The drive rod 11 rotates continuously under the action of the drive motor. The drive rod 11 drives the connecting strip 3, the fine hydrophilic droplet brush 31, and the drainage groove plate 32 to rotate continuously. The fine hydrophilic droplet brush 31 will come into contact with the droplets in the convergence state. When the fine hydrophilic droplet brush 31 comes into contact with the droplets, it will destroy the surface tension of the droplets. Under the influence of the hydrophobicity of the inner surface coating of the heat insulation coating cone sleeve 2, the hydrophilicity of the fine hydrophilic droplet brush 31, and the capillary action generated between the bristles of the finely distributed fine hydrophilic droplet brush 31, the droplets will move towards the fine hydrophilic droplet brush 31. The water flows through the gaps between the bristles of the dense hydrophilic water droplet brush 31 and the fine hydrophilic water droplet brush 31. As the liquid volume increases, it converges towards the fine hydrophilic water droplet brush 31 and the diversion trough plate 32. Then, it flows along the diversion trough plate 32 to the collection trough 14 and converges in the collection pipe 13. The fine hydrophilic water droplet brush 31 is close to but does not contact the heat insulation coating cone sleeve 2, which can prevent the droplets from dripping back into the menthol grading dehydration tank body 1 and affecting the dehydration efficiency. It will not directly contact the inner wall of the heat insulation coating cone sleeve 2, effectively reducing the wear of the heat insulation coating cone sleeve 2 and the impact of friction-generated microparticles on the quality of the finished liquid.
