Description

Technical Field

[0001] This utility model relates to the field of lemongrass essential oil processing technology, specifically to a lemongrass essential oil purification and separation device. Background Technology

[0002] Lemongrass, also known as lemongrass, is a perennial herbaceous plant belonging to the genus Lemongrass in the family Poaceae. Lemongrass essential oil can be extracted from it and used to make perfumes, aromatherapy products, sachets, etc., with effects such as aiding sleep, repelling mosquitoes, and deodorizing. In addition, lemongrass essential oil can be used to preserve fruits, vegetables, meats, and other foods, as well as as a control agent for stored pests. The purification and separation of lemongrass essential oil is a crucial process that involves further removing impurities after extracting the crude essential oil from the lemongrass raw material, thereby improving the purity, aroma quality, and proportion of functional components. Its core objective is to achieve the dual goals of "enriching effective components" and "removing impurities" through targeted technologies based on the physicochemical properties of different components in the essential oil.

[0003] In existing lemongrass essential oil purification and separation devices, the raw material is generally introduced into the processing device, then chopped by blades and heated for purification. However, the existing crushing structure is often simple, with only one rotating shaft driving the blades to rotate, which reduces the crushing effect of the raw material and is not conducive to improving work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a lemongrass essential oil purification and separation device to solve the problem mentioned in the background art that the existing crushing structure is often simple and only uses a single rotating shaft to drive the blades to rotate, which reduces the effect of raw material crushing and is not conducive to improving work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lemongrass essential oil purification and separation device, comprising a protective shell with two feed pipes installed through its side surface, a discharge pipe installed through its lower side surface, a drive motor fixedly connected to the lower surface of the protective shell, a main crushing column installed on the bottom surface of the cavity of the protective shell, an upper cover plate provided at the upper end of the protective shell, a linkage rotating block installed on the lower surface of the upper cover plate, a limit block fixedly connected to the upper end of the main crushing column, an auxiliary crushing mechanism provided on the lower surface of the upper cover plate, which drives the linkage rotating block to rotate through the main crushing column and the limit block, thereby driving the transmission gear, the linkage gear and the auxiliary crushing column to rotate for crushing, and a purification mechanism provided on the side surface of the protective shell.

[0006] Preferably, the bottom surface of the protective shell cavity is inclined, the main crushing column is rotatably connected to the protective shell, and the rotating shaft of the main crushing column is fixedly connected to the output end of the drive motor. The linkage rotating block is rotatably connected to the upper cover plate, and a cross-shaped groove is provided on the lower surface of the linkage rotating block. The limiting plug is cross-shaped, and the limiting plug and the linkage rotating block are engaged.

[0007] By adopting the above technical solution, gravity can be used to automatically gather the crushed raw material residue or incompletely crushed material towards the discharge pipe, avoiding the accumulation of material at the bottom of the shell, eliminating the need for manual cleaning, reducing maintenance costs, and ensuring that subsequent crushing operations are not affected by accumulated material, thus improving the overall smoothness of the device's operation.

[0008] Preferably, the auxiliary crushing mechanism includes a transmission gear, which is fixedly connected to the upper surface of the linkage rotating block. Linkage gears are provided on both sides of the transmission gear, and two auxiliary crushing columns are rotatably connected to the lower surface of the upper cover plate.

[0009] By adopting the above technical solution, it can rotate synchronously with the linkage block, converting the power transmitted by the linkage block into its own rotational power, providing a power source for driving the linkage gear to rotate. This is a key link in the power transmission of the auxiliary crushing mechanism, ensuring that the power can be smoothly transmitted to the subsequent components.

[0010] Preferably, both the transmission gear and the linkage gear are rotatably connected to the upper cover plate, and the transmission gear and the linkage gear are meshed. The rotating shaft of the auxiliary crushing column is fixedly connected to the rotating shaft of the linkage gear.

[0011] By adopting the above technical solution, the top cover provides stable installation and rotation support for both, ensuring that the axial position of both is fixed during rotation, avoiding poor meshing due to gear misalignment, ensuring the stability and accuracy of gear transmission, reducing gear wear, and extending the service life of the equipment.

[0012] Preferably, the purification mechanism on the side of the protective shell includes a side-mounted housing, a condensation pipe is fixedly connected inside the side-mounted housing, a discharge pipe is fixedly installed on the lower surface of the side-mounted housing, a filter screen frame is installed through the lower side surface of the side-mounted housing, and a positioning block is provided on the lower surface of the side-mounted housing.

[0013] By adopting the above technical solution, purification components such as condensation pipes and filter frames can be installed in a centralized manner, making the purification mechanism compact, facilitating the overall layout and maintenance of the equipment, and protecting the internal purification components from the influence of the external environment, thus ensuring the stable operation of the purification process.

[0014] Preferably, the front surface of the side-mounted enclosure is provided with a heat dissipation fan, and the rear surface of the side-mounted enclosure is provided with a heat dissipation opening. The condensation pipe has a serpentine design, and both ends of the condensation pipe are respectively connected to the protective shell and the lower cavity of the side-mounted enclosure.

[0015] By adopting the above technical solution, the cooling fan can accelerate the airflow inside the side-mounted enclosure, and discharge the heat generated during the condensation process through the heat dissipation opening, effectively reducing the internal temperature of the side-mounted enclosure, providing a good heat dissipation environment for the condensation pipe, ensuring that the condensation pipe can continuously and efficiently condense the essential oil vapor, and improving the condensation effect and efficiency.

[0016] Preferably, a trapezoidal limiting block is provided at one end of the filter frame, and a groove is provided on the lower surface of the limiting block. The positioning plug is slidably connected to the side mounting box, and a spring is connected between the positioning plug and the side mounting box. The positioning plug and the filter frame are also engaged.

[0017] Using the above technical solution, the trapezoidal limiting block can limit the insertion depth of the filter frame, ensuring the accurate installation position of the filter frame and avoiding the filter effect being affected by insertion that is too deep or too shallow. The limiting block can also prevent the filter frame from completely entering the side mounting box, making it easier to disassemble the filter frame for cleaning or replacement later.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the lemongrass essential oil purification and separation device: 1. By using the main crushing column and the auxiliary crushing column in tandem, the problem of insufficient crushing in traditional single crushing structures is solved. The main crushing column, driven by the drive motor, initially crushes the raw material, while the auxiliary crushing column rotates synchronously through the limit block, linkage block and gear set, increasing the crushing range and number of crushing operations. This makes the lemongrass raw material crushed more evenly and thoroughly, laying a good foundation for subsequent essential oil extraction and greatly improving the overall processing efficiency. 2. The serpentine design of the condenser pipe, combined with the cooling fan and opening of the side-mounted housing, increases the heat dissipation area, extends the steam residence time, and improves the condensation efficiency of essential oils. The filter frame can effectively filter impurities in the liquid mixture, improve the purity of essential oils, and the spring-locking structure of the positioning blocks makes the filter frame easier to disassemble and clean, reducing maintenance time and ensuring the continuous and stable operation of the equipment. 3. The inclined design of the bottom surface of the protective shell cavity utilizes gravity to automatically collect residues into the discharge pipe, avoiding material accumulation. The precise connection structure between components ensures stable power transmission and smooth operation of components, reducing the probability of equipment failure and improving the overall practicality and service life of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6This utility model provides a technical solution: a lemongrass essential oil purification and separation device, including a protective shell 1, a feed pipe 2, a discharge pipe 3, a drive motor 4, a main crushing column 5, an upper cover plate 6, a linkage rotating block 7, a limiting insert 8, a transmission gear 9, a linkage gear 10, an auxiliary crushing column 11, a side mounting box 12, a condensation pipe 13, a discharge pipe 14, a filter screen frame 15, and a positioning insert 16. The protective shell 1 has two feed pipes 2 installed through its side surface, and a discharge pipe 3 is installed through its lower side surface. The bottom surface of the cavity of the protective shell 1 is inclined. The main crushing column 5 and the protective shell 1 are connected... The outer shell 1 forms a rotating connection, and the rotating shaft of the main crushing column 5 is fixedly connected to the output end of the drive motor 4. The linkage rotating block 7 forms a rotating connection with the upper cover plate 6, and the lower surface of the linkage rotating block 7 is provided with a cross-shaped groove. The limiting plug 8 is designed in a cross shape, and the limiting plug 8 and the linkage rotating block 7 form a snap-fit ​​connection. When lemongrass raw material is put into the protective outer shell 1 through the feeding pipe 2, the drive motor 4 is started. Since the rotating shaft of the main crushing column 5 is fixedly connected to the output end of the drive motor 4, and the main crushing column 5 and the protective outer shell 1 form a rotating connection, the drive motor 4 drives the main crushing column 5 to rotate, and performs preliminary crushing operation on the input raw material.

[0023] A drive motor 4 is fixedly connected to the lower surface of the protective shell 1. A main crushing column 5 is installed on the bottom surface of the cavity of the protective shell 1. An upper cover plate 6 is provided at the upper end of the protective shell 1. A linkage rotating block 7 is installed on the lower surface of the upper cover plate 6. The auxiliary crushing mechanism includes a transmission gear 9, which is fixedly connected to the upper surface of the linkage rotating block 7. Linkage gears 10 are provided on both sides of the transmission gear 9. Two auxiliary crushing columns 11 are rotatably connected to the lower surface of the upper cover plate 6. The transmission gear 9 and the linkage gears 10 are rotatably connected to the upper cover plate 6, and the transmission gear 9 and the linkage gears 10 are meshed. Next, the rotating shaft of the auxiliary crushing column 11 is fixedly connected to the rotating shaft of the linkage gear 10. The cross-shaped limiting block 8 at the upper end of the main crushing column 5 engages with the cross-shaped groove on the lower surface of the linkage rotating block 7. When the main crushing column 5 rotates, it drives the linkage rotating block 7 to rotate synchronously. The transmission gear 9 on the upper surface of the linkage rotating block 7 rotates accordingly. Since the transmission gear 9 meshes with the linkage gears 10 on both sides and both are rotatably connected to the upper cover plate 6, the transmission gear 9 drives the linkage gear 10 to rotate, thereby causing the auxiliary crushing column 11, which is fixed to the rotating shaft of the linkage gear 10, to rotate and cooperate with the main crushing column 5 to complete the secondary crushing.

[0024] The upper end of the main crushing column 5 is fixedly connected to a limiting block 8. The purification mechanism on the side of the protective shell 1 includes a side-mounted housing 12. A condensation pipe 13 is fixedly connected inside the side-mounted housing 12. A discharge pipe 14 is fixedly installed on the lower surface of the side-mounted housing 12. A filter screen frame 15 is installed through the lower side surface of the side-mounted housing 12. A positioning block 16 is provided on the lower surface of the side-mounted housing 12. A cooling fan is provided on the front surface of the side-mounted housing 12, and a cooling fan is provided on the rear surface of the side-mounted housing 12. The opening and the condensing pipe 13 are designed in a serpentine shape, and the two ends of the condensing pipe 13 are connected to the lower cavity of the protective shell 1 and the side mounting box 12, respectively. The crushed raw material is processed in the protective shell 1 to produce steam containing essential oil. The steam enters the serpentine condensing pipe 13 connected to the protective shell 1. The heat dissipation fan on the front surface of the side mounting box 12 cooperates with the heat dissipation opening on the rear surface to accelerate the heat dissipation, so that the steam is condensed into a liquid mixture in the condensing pipe 13 and then flows into the lower cavity of the side mounting box 12.

[0025] An auxiliary crushing mechanism is provided on the lower surface of the upper cover plate 6. It drives the linkage rotating block 7 to rotate through the main crushing column 5 and the limiting block 8, thereby driving the transmission gear 9, the linkage gear 10 and the auxiliary crushing column 11 to rotate for crushing. A purification mechanism is provided on the side surface of the protective shell 1. A trapezoidal limiting block is provided at one end of the filter screen frame 15. A groove is provided on the lower surface of the limiting block of the filter screen frame 15. The positioning block 16 is slidably connected to the side mounting box 12, and a spring is connected between the positioning block 16 and the side mounting box 12. Furthermore, the positioning plug 16 and the filter frame 15 are engaged. The liquid mixture passes through the filter frame 15 installed through the lower side surface of the side mounting box 12, and impurities are filtered and intercepted. The filtered pure essential oil is discharged and collected through the discharge pipe 14 on the lower surface of the side mounting box 12. The broken residue inside the protective shell 1 automatically gathers and is discharged into the discharge pipe 3 due to the inclined design of the bottom surface of the cavity. The filter frame 15 is fixed by the positioning plug 16. When cleaning is required, the positioning plug 16 can be pulled to disassemble it.

[0026] Working principle: When using this lemongrass essential oil purification and separation device, lemongrass raw material is fed into the protective shell 1 through the feed pipe 2. The drive motor 4 drives the main crushing column 5 to rotate and initially crush the raw material. The main crushing column 5 drives the linkage rotating block 7 to rotate through the cross-shaped limit plug 8, so that the transmission gear 9 drives the linkage gears 10 on both sides, and then the auxiliary crushing column 11 rotates to complete the secondary crushing. The essential oil vapor generated after crushing enters the serpentine condensation pipe 13 in the side mounting box 12. Under the heat dissipation effect of the cooling fan and the opening, it condenses into a liquid mixture and flows into the cavity at the lower end of the side mounting box 12. After the mixture passes through the filter screen frame 15 to filter impurities, the pure essential oil is discharged from the discharge pipe 14. The residue in the protective shell 1 is discharged from the impurity discharge pipe 3 along the inclined bottom surface. The filter screen frame 15 can be disassembled and cleaned by pulling the positioning plug 16, which increases the overall practicality.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
