Description

Technical Field

[0001] This utility model relates to the field of plant essential oil extraction technology, specifically a plant essential oil extraction condensation device. Background Technology

[0002] Plant essential oils are aromatic substances unique to plants, extracted from their flowers, leaves, roots, bark, fruits, seeds, and resins through methods such as distillation and pressing. Due to their unique aroma and diverse functions, plant essential oils are widely used in fragrances, medicines, cosmetics, and food. Efficient and pure essential oil extraction processes are crucial for ensuring product quality and improving economic benefits; in the extraction process, condensation equipment plays a key role.

[0003] Patent CN214400419U discloses a condensation device for distillation extraction of plant essential oils, comprising at least two sets of condensation units arranged sequentially. Each condensation unit includes a condensation mechanism and a collection mechanism. The collection mechanism includes a hollow storage box with a drain pipe at the bottom and an end cap at the lower end. A third connecting pipe and a fourth connecting pipe are located at the upper end of the storage box. The third connecting pipe is connected to a second connecting pipe, and a bent pipe is screwed onto the fourth connecting pipe. A first connecting pipe on a subsequent condensation unit is detachably connected to the bent pipe on the preceding condensation unit. The condensation units of this invention can be used in combination for thorough condensation, and the condenser pipes in a single condensation unit have shorter length and inner diameter requirements, reducing the likelihood of temporary blockage.

[0004] The existing technology uses multiple condensation units in combination, with a spiral condenser tube fixed inside the cylinder. Cooling water flow lowers the steam temperature, causing the essential oils and water in the steam to condense into liquid, thus recovering the essential oils. However, during condensation, the steam not only contains essential oils but also carries impurities from the plant materials, such as tiny solid particles, pigments, and resins. These impurities easily deposit on the inner wall of the spiral condenser tube, forming a scale layer. This scale layer significantly reduces the thermal conductivity of the condenser tube, hindering effective heat transfer and consequently reducing condensation efficiency and the final condensation effect. To maintain condensation efficiency, the spiral condenser tube needs to be cleaned or replaced regularly. However, existing condenser tube designs are usually fixed inside the cylinder, making disassembly and replacement complex and time-consuming, leading to extended downtime for maintenance and significantly impacting overall processing efficiency. Therefore, we propose a plant essential oil extraction condensation device. Utility Model Content

[0005] The purpose of this invention is to provide a plant essential oil extraction and condensation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plant essential oil extraction condensation device includes a condensation tank. The bottom of the outer wall of the condensation tank is provided with a water inlet pipe, and the outer wall of the condensation tank is provided with a water outlet pipe near the top. Cold water enters the condensation tank from the water inlet pipe, and the water is output from the water outlet pipe after heat exchange, thereby generating a cooling water flow from bottom to top in the condensation tank, which exchanges heat with the steam in the spiral condenser tube, thereby realizing the condensation of the steam.

[0008] The top of the condenser is provided with a detachable lid. The lid is the top cover of the condenser and has a detachable function. It is used to seal the condenser and supports the installation of the spiral condenser tube through its structure. The condenser is provided with a detachable spiral condenser tube. The spiral condenser tube is used to contain steam and exchange heat with cooling water, so that the essential oil and water in the steam condense into liquid. The steam enters through the inlet end of the spiral condenser tube and discharges the condensate from the outlet end.

[0009] A circular hole is provided in the middle of the top of the inner wall of the barrel lid for the inlet end of the spiral condenser to pass through. A distillation tube is sleeved on the inlet end of the spiral condenser to guide steam into the spiral condenser for condensation. A liquid outlet pipe is provided through the middle of the bottom of the condensing barrel. The outlet end of the spiral condenser is inserted into the liquid outlet pipe to receive the condensate flowing out of the outlet end of the spiral condenser and guide it out of the condensing device.

[0010] Preferably, the bottom of the outer wall of the bucket lid is provided with a second annular connecting plate, and the top of the second annular connecting plate is provided with four mounting holes arranged in a ring array, and fastening bolts are connected in the mounting holes.

[0011] Preferably, the top of the outer wall of the condenser is provided with a first annular connecting plate. The top of the first annular connecting plate is provided with a threaded groove for fastening bolts to be threadedly connected. The fastening bolts are set in the mounting holes of the second annular connecting plate and are threadedly connected to the threaded groove of the first annular connecting plate. This is used to fix the lid tightly to the condenser and facilitate the disassembly and assembly of the lid by the operator.

[0012] Preferably, a sealing ring is bonded inside the circular hole, and the inner wall of the sealing ring is tightly fitted with the outer wall of the spiral condenser tube to enhance the sealing performance between the circular hole and the spiral condenser tube.

[0013] Preferably, a second sealing rubber gasket is embedded at the bottom of the inner wall of the distillation tube. The inner wall of the second sealing rubber gasket is in close contact with the outer wall of the inlet end of the spiral condenser. The second sealing rubber gasket is used to tightly fit with the outer wall of the inlet end of the spiral condenser to play a sealing role and prevent steam leakage.

[0014] Preferably, a third sealing rubber gasket is embedded at the top of the inner wall of the liquid outlet pipe, and the inner wall of the third sealing rubber gasket is in close contact with the outer wall of the spiral condenser outlet end to ensure the sealing and smooth flow of the liquid.

[0015] Preferably, a sealing sleeve is provided on the outer wall of the spiral condenser near the bottom end, and the bottom of the sealing sleeve abuts against the bottom of the inner wall of the condenser, thereby fixing the spiral condenser and providing a sealing function.

[0016] When it is necessary to disassemble the spiral condenser, the operator first removes the four fastening bolts, then moves the distillation tube upward to separate the distillation tube from the inlet end of the spiral condenser. Next, the bucket lid is moved upward to move the inlet end of the spiral condenser out of the round hole. After removing the bucket lid, the operator moves the spiral condenser upward to separate the outlet end of the spiral condenser and the sealing sleeve from the liquid outlet pipe. This allows for quick disassembly of the spiral condenser, facilitating the later maintenance of the condensing device.

[0017] Preferably, the inner wall of the sealing sleeve is embedded with a first sealing rubber gasket, and the inner wall of the first sealing rubber gasket is in close contact with the outer wall of the liquid outlet pipe to ensure sealing performance and prevent liquid leakage.

[0018] Preferably, an annular positioning plate is provided on the outer wall of the spiral condenser near the top, and the top of the annular positioning plate abuts against the top of the inner wall of the bucket lid to position the spiral condenser.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This plant essential oil extraction and condensation device, by designing the spiral condenser tube as a detachable structure and forming a cooling water flow from bottom to top in the condensation tank, effectively improves the condensation efficiency. The steam can fully exchange heat with the cooling water in the spiral condenser tube, so that the essential oil and water can be quickly condensed into liquid.

[0021] 2. The plant essential oil extraction and condensation device, through the reasonable design of the barrel lid, sealing sleeve and annular positioning plate, allows the spiral condenser tube to be easily disassembled and installed. When it is necessary to clean or replace the spiral condenser tube, the staff only needs to remove the fastening bolts and barrel lid to quickly disassemble the spiral condenser tube, which greatly shortens the downtime for maintenance and improves the processing efficiency.

[0022] 3. This plant essential oil extraction condenser enhances its sealing performance by using sealing rings, a first sealing rubber gasket, a second sealing rubber gasket, and a third sealing rubber gasket in key areas. The first and third sealing rubber gaskets effectively prevent condensate leakage; the second sealing rubber gasket ensures the seal between the distillation tube and the inlet end of the spiral condenser. These measures together guarantee the sealing performance of the device and improve the operational reliability of the condenser.

[0023] 4. This plant essential oil extraction and condensation device addresses the shortcomings of existing technologies where the condenser tube is fixed inside the cylinder and difficult to disassemble. It innovatively designs a docking structure between the lid and the condensation tank. Through the combination of the first annular docking plate, the second annular docking plate, and fastening bolts, the lid can be quickly disassembled and assembled. At the same time, the spiral condenser tube and the sealing sleeve at the bottom of the condensation tank are only in contact, without the need for additional complex fixing, which greatly facilitates the maintenance and use of the device.

[0031] Please see Figures 1-4 This utility model provides a technical solution:

[0032] A plant essential oil extraction condensation device includes a condensation tank 1. A water inlet pipe 10 is provided at the bottom of the outer wall of the condensation tank 1, and a water outlet pipe 11 is provided on the outer wall of the condensation tank 1 near the top. Cold water enters the condensation tank 1 from the water inlet pipe 10, and the water is output from the water outlet pipe 11 after heat exchange, thereby generating a cooling water flow from bottom to top in the condensation tank 1 to exchange heat with the steam in the spiral condenser tube 3, thereby realizing the condensation of the steam.

[0033] The top of the condenser tank 1 is provided with a removable tank cover 2. The tank cover 2 is the top cover of the condenser tank 1 and has a removable function. It is used to seal the condenser tank 1 and supports the installation of the spiral condenser tube 3 through its structure. The condenser tank 1 is provided with a removable spiral condenser tube 3. The spiral condenser tube 3 is used to contain steam and exchange heat with cooling water, so that the essential oil and water in the steam condense into liquid. The steam enters through the inlet end of the spiral condenser tube 3 and discharges the condensate from the outlet end.

[0034] A circular hole 20 is provided in the middle of the top of the inner wall of the barrel lid 2 for the input end of the spiral condenser tube 3 to pass through. A distillation tube 4 is sleeved on the input end of the spiral condenser tube 3. The distillation tube 4 is sleeved on the input end of the spiral condenser tube 3 to guide steam into the spiral condenser tube 3 for condensation. A liquid outlet pipe 5 is provided through the middle of the bottom of the condensing barrel 1. The output end of the spiral condenser tube 3 is inserted into the liquid outlet pipe 5 to receive the condensate flowing out of the output end of the spiral condenser tube 3 and guide it out of the condensing device.

[0035] In this embodiment, a second annular connecting plate 21 is provided at the bottom of the outer wall of the bucket lid 2. The top of the second annular connecting plate 21 is provided with four mounting holes 210 arranged in a ring array. Fastening bolts 6 are connected in the mounting holes 210.

[0036] Specifically, the top of the outer wall of the condenser tank 1 is provided with a first annular connecting plate 12. The top of the first annular connecting plate 12 is provided with a threaded groove for the fastening bolt 6 to be threaded. The fastening bolt 6 is set in the mounting hole 210 of the second annular connecting plate 21 and is threadedly connected to the threaded groove of the first annular connecting plate 12. This is used to fix the tank cover 2 tightly to the condenser tank 1, making it convenient for workers to disassemble and assemble the tank cover 2.

[0037] Furthermore, a sealing ring 7 is bonded inside the round hole 20. The inner wall of the sealing ring 7 is tightly fitted with the outer wall of the spiral condenser tube 3 to enhance the sealing performance between the round hole 20 and the spiral condenser tube 3.

[0038] Furthermore, a second sealing rubber gasket 40 is embedded at the bottom of the inner wall of the distillation tube 4. The inner wall of the second sealing rubber gasket 40 is tightly fitted with the outer wall of the input end of the spiral condenser tube 3. The second sealing rubber gasket 40 is used to tightly fit with the outer wall of the input end of the spiral condenser tube 3 to play a sealing role and prevent steam leakage.

[0039] Furthermore, a third sealing rubber gasket 50 is embedded at the top of the inner wall of the liquid outlet pipe 5. The inner wall of the third sealing rubber gasket 50 is tightly fitted with the outer wall of the output end of the spiral condenser pipe 3 to ensure the sealing and smooth flow of the liquid.

[0040] Furthermore, a sealing sleeve 31 is provided on the outer wall of the spiral condenser tube 3 near the bottom. The bottom of the sealing sleeve 31 abuts against the bottom of the inner wall of the condenser tank 1, thereby fixing the spiral condenser tube 3 and providing a sealing function.

[0041] When it is necessary to disassemble the spiral condenser tube 3, the operator first removes the four fastening bolts 6, then moves the distillation tube 4 upward to separate the distillation tube 4 from the input end of the spiral condenser tube 3. Next, the bucket cover 2 is moved upward to move the input end of the spiral condenser tube 3 out of the round hole 20. After removing the bucket cover 2, the operator moves the spiral condenser tube 3 upward to separate the output end of the spiral condenser tube 3 and the sealing sleeve 31 from the liquid outlet pipe 5. This allows for quick disassembly of the spiral condenser tube 3, facilitating the later maintenance of the condensation device.

[0042] Furthermore, a first sealing rubber gasket 32 ​​is embedded in the inner wall of the sealing sleeve 31. The inner wall of the first sealing rubber gasket 32 ​​is tightly fitted with the outer wall of the liquid outlet pipe 5 to ensure sealing performance and prevent liquid leakage.

[0043] Furthermore, an annular positioning plate 30 is provided on the outer wall of the spiral condenser tube 3 near the top. The top of the annular positioning plate 30 abuts against the top of the inner wall of the lid 2 to position the spiral condenser tube 3.

[0044] In this embodiment, the plant essential oil extraction and condensation device is used by connecting a cooling water source through the inlet pipe 10 and the outlet pipe 11 to the drainage channel to ensure that the cooling water in the condensation tank 1 forms a bottom-up circulating flow. The distillation tube 4 is fitted onto the inlet end of the spiral condenser tube 3. The second sealing rubber gasket 40 on the inner wall of the distillation tube 4 and the sealing ring 7 in the round hole 20 are checked to ensure a tight fit with the outer wall of the spiral condenser tube 3, preventing steam leakage. The cooling water supply is started, and the cooling water enters the condensation tank 1 through the inlet pipe 10. After sufficient heat exchange with the outer wall of the spiral condenser tube 3, it is discharged from the outlet pipe 11. Simultaneously, steam is introduced into the spiral condenser tube 3 through the distillation tube 4, causing it to condense during the heat exchange process. The condensate forms a liquid and enters the outlet pipe 5 through the output end of the spiral condenser 3. Check the third sealing rubber gasket 50 and sealing sleeve 31 at the top of the outlet pipe 5 to ensure that the output end of the spiral condenser 3 is tightly fitted to the outer wall of the outlet pipe 5 to prevent condensate leakage. The condensate is eventually discharged and collected smoothly through the outlet pipe 5. When the spiral condenser 3 needs to be cleaned or replaced, first loosen the fastening bolt 6, move the bucket cover 2 upward and remove it. Through the design of the annular positioning plate 30 and sealing sleeve 31, the spiral condenser 3 can be easily removed from the condensation bucket 1. After maintenance, reinstall the spiral condenser 3 and ensure that all sealing components are installed correctly. The equipment can then be put into safe and efficient use.
