Description

Technical Field

[0001] This utility model relates to the field of plant essential oil capsule preparation technology, specifically a plant essential oil nano-microcapsule preparation device. Background Technology

[0002] Plant essential oils, botanically known as essential oils and chemically and medicinally as volatile oils, are mostly volatile, strongly aromatic oily liquids at room temperature. They are mainly composed of compounds with small molecular weights and can be evaporated with water vapor. To improve the stability of plant essential oils and prolong their efficacy, chitosan microcapsules are usually used to encapsulate the essential oils. In the preparation of plant essential oil capsules, isophorone diisocyanate is first added to the plant essential oil and stirred to obtain the oil phase. Chitosan nanocrystals are then added to water and mixed to obtain the aqueous phase. Finally, the oil phase is added to the aqueous phase, and the mixture is sheared, polymerized, and cooled to obtain plant essential oil nanocapsules.

[0003] In existing plant essential oil capsules, the oil and water phases are stirred using two independent stirring devices, which require two motors to drive the stirring rods. The devices occupy a large area, and after the capsules are prepared, both stirring devices need to be cleaned, which requires a lot of water and increases the workload for workers, making it quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a device for preparing plant essential oil nanocapsules to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for preparing plant essential oil nanocapsules, comprising:

[0007] A mixing chamber, wherein a partition is fixedly installed inside the mixing chamber;

[0008] A feeding assembly is fixedly installed on the outer surface of the mixing chamber, the feeding assembly including a first annular pipe fixedly installed on the outer surface of the mixing chamber;

[0009] A stirring assembly is rotatably connected inside the stirring chamber. The stirring assembly includes a rotating shaft, a shear head is fixedly installed at the lower end of the rotating shaft, and multiple stirring blades are arranged on the outer side of the rotating shaft above the partition.

[0010] Clean the components and securely install them on the upper part of the mixing chamber.

[0011] Furthermore, a No. 1 feed pipe is fixedly embedded in the upper end of the mixing chamber, a No. 2 feed pipe that penetrates the partition is embedded in the outer surface of the mixing chamber, a No. 1 discharge valve is fixedly connected to the outer surface of the mixing chamber above the partition, and a No. 2 discharge valve is fixedly connected to the lower end of the outer surface of the mixing chamber.

[0012] Preferably, a water distribution pipe connected to the mixing chamber is fixedly embedded at an equal angle on the outer surface of the first annular pipe, and a flexible hose is fixedly connected to one end of the first annular pipe, with one end of the flexible hose fixedly connected to the first discharge valve.

[0013] Furthermore, a round tube is fixedly installed on the upper surface of the partition plate outside the rotating shaft, and a No. 1 bearing is fixedly embedded in the upper end of both the partition plate and the mixing chamber. The rotating shaft is fixedly inserted through the inner rings of the two No. 1 bearings, and a motor capable of driving the rotating shaft to rotate is fixedly installed at the upper end of the mixing chamber.

[0014] Preferably, a second bearing is fixedly installed on the outer side of the circular tube, a fixing frame is fixedly installed on the outer ring of the second bearing, the upper end of the fixing frame is fixedly connected to the rotating shaft, and multiple stirring blades are fixedly connected to the fixing frame.

[0015] Furthermore, the cleaning component includes:

[0016] The No. 2 annular pipe is fixedly installed at the upper end of the inside of the mixing chamber;

[0017] The tee pipe is fixedly installed at one end of the No. 2 ring pipe;

[0018] Two solenoid valves are fixedly installed at both ends of the three-way pipe;

[0019] An air pump is fixedly installed on the upper surface of the mixing chamber.

[0020] Preferably, one end of the air pump is fixedly connected to a solenoid valve through an air pipe, and multiple No. 1 water distribution holes are equidistantly opened on the outer side of the No. 2 annular pipe, and multiple No. 2 water distribution holes at different angles are equidistantly opened on the inner side of the No. 2 annular pipe.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The motor drives the rotating shaft to rotate, causing the shear head and stirring blades to rotate simultaneously, thus stirring the oil and water phases at the same time. The first discharge valve opens, and the oil phase is mixed into the water phase from multiple locations through multiple water distribution pipes, accelerating the mixing speed of the two. At the same time, the rotation of the shear head accelerates the mixing speed of the water and oil phases through shearing force. Thus, by dividing a mixing chamber into upper and lower spaces, and having a rotating shaft drive the stirring blades and shear head to rotate, the oil and water phases are stirred simultaneously by a single stirring device, reducing the footprint of the stirring device.

[0023] 2. Another solenoid valve is connected to an external water source. The first discharge valve is closed, allowing water to flush the inner wall of the mixing chamber and the mixing components. After the prepared solution is discharged, the air pump operates to pressurize the upper space of the mixing chamber, giving the cleaning water more pressure to spray out from the water distribution pipe, so that it washes the shear head. At the same time, the rotation of the shear head agitates the water, improving the cleaning effect. Thus, after preparation, it is easy to discharge the wastewater from cleaning the upper space into the lower space for reuse, reducing the cleaning water consumption and the workload of workers, making it easier to use.

[0030] 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.

[0031] Please see Figure 1-5In this embodiment of the invention, a plant essential oil nanocapsule preparation device includes a stirring chamber 1. A partition 101 is fixedly installed inside the stirring chamber 1, dividing the interior of the stirring chamber 1 into two stirring spaces. A first feed pipe 102 is fixedly embedded in the upper end of the stirring chamber 1, through which oil phase raw materials are fed into the upper stirring space. A second feed pipe 103, penetrating the partition 101, is embedded in the outer surface of the stirring chamber 1, through which aqueous phase raw materials are fed into the lower stirring space. After feeding is completed, feed pipe 102 and feed pipe 103 are sealed. Feeding component 2 is fixedly installed on the outer surface of mixing chamber 1. Feeding component 2 includes a first annular pipe 201 fixedly installed on the outer surface of mixing chamber 1. Mixing component 3 is rotatably connected to the inside of mixing chamber 1. Mixing component 3 includes a rotating shaft 302. A shearing head 305 is fixedly installed at the lower end of rotating shaft 302. Multiple mixing blades 308 are arranged on the outer side of rotating shaft 302 above partition 101. Cleaning component 4 is fixedly installed at the upper end of mixing chamber 1.

[0032] Specifically, the stirring component 3 stirs the oil phase and the water phase. After the oil phase is stirred evenly, the feeding component 2 mixes the oil phase into the water phase and stirs and shears it again to make the two evenly mixed. After the stirring is finished, the cleaning component 4 rinses the inside of the stirring chamber 1.

[0033] Example 1

[0034] like Figure 2 As shown, in this embodiment, a discharge valve 104 is fixedly connected to the outer surface of the mixing chamber 1 above the partition 101, and a discharge valve 105 is fixedly connected to the lower end of the outer surface of the mixing chamber 1; a water distribution pipe 202 connected to the mixing chamber 1 is fixedly embedded at an equal angle on the outer surface of the first annular pipe 201, and a flexible hose 203 is fixedly connected to one end of the first annular pipe 201, and one end of the flexible hose 203 is fixedly connected to the first discharge valve 104.

[0035] In this embodiment, the first discharge valve 104 is opened to discharge the oil phase into the first annular pipe 201. Then, through multiple water distribution pipes 202, the oil phase is mixed into the aqueous phase from multiple locations to accelerate the mixing speed. After the mixture is evenly mixed, the prepared solution is discharged from the second discharge valve 105.

[0036] like Figure 2-4As shown, in this embodiment, a circular tube 301 is fixedly installed on the upper surface of the partition 101 outside the rotating shaft 302. The circular tube 301 prevents the oil phase from contacting the rotating shaft 302, thus preventing the oil phase from seeping out from the part of the rotating shaft 302 that penetrates the partition 101. A first bearing 303 is fixedly embedded in the upper end of both the partition 101 and the mixing chamber 1. The first bearing 303 increases the stability of the rotating shaft 302 when it rotates. The rotating shaft 302 is fixedly inserted through the inner rings of the two first bearings 303. A motor 304 capable of driving the rotating shaft 302 is fixedly installed at the upper end of the mixing chamber 1. A second bearing 306 is fixedly installed on the outer side of the circular tube 301. The second bearing 306 increases the stability of the fixed frame 307 when it rotates. A fixed frame 307 is fixedly installed on the outer ring of the second bearing 306. The upper end of the fixed frame 307 is fixedly connected to the rotating shaft 302. Multiple stirring blades 308 are fixedly connected to the fixed frame 307.

[0037] In practice, the motor 304 operates, driving the rotating shaft 302 to rotate, causing the shear head 305 and the stirring blade 308 to rotate simultaneously, stirring the oil phase and the water phase at the same time. Simultaneously, the rotation of the shear head 305 accelerates the mixing speed of the water phase and the oil phase through shearing force. Thus, by dividing a mixing chamber 1 into upper and lower spaces, and having a rotating shaft 302 drive the stirring blade 308 and the shear head 305 to rotate, the oil phase and the water phase are stirred simultaneously through a single stirring device, reducing the footprint of the stirring device.

[0038] Example 2

[0039] Based on Example 1, in order to compensate for the problem that the interior of the mixing chamber 1 is not easy to clean.

[0040] like Figure 2 and Figure 5 As shown, in this embodiment, the cleaning component 4 includes: a second annular pipe 401 fixedly installed at the upper end of the mixing chamber 1, a three-way pipe 402 fixedly installed at one end of the second annular pipe 401, two solenoid valves 403 fixedly installed at both ends of the three-way pipe 402, and an air pump 404 fixedly installed on the upper surface of the mixing chamber 1; one end of the air pump 404 is fixedly connected to a solenoid valve 403 through an air pipe, and multiple first water distribution holes 405 are equidistantly opened on the outer side of the surface of the second annular pipe 401, and multiple second water distribution holes 406 at different angles are equidistantly opened on the inner side of the surface of the second annular pipe 401.

[0041] In practice, another solenoid valve 403 is connected to an external water source, allowing water to be pumped into the second annular pipe 401. While the oil and water phases are being mixed, the first discharge valve 104 is closed, and water is sprayed out from different angles through the first water distribution hole 405 and the second water distribution holes 406 at different angles to rinse the inner wall of the mixing chamber 1 and the mixing assembly 3. Simultaneously, the rinsing surface is increased by the stirring blades 308. After the prepared solution is discharged, the air pump 404 operates to purify the upper space of the mixing chamber 1. When the discharge valve 104 is opened, more pressure is applied to the cleaning water, which is then sprayed out from the water distribution pipe 202 to flush the shear head 305. After the pressure is released, the water slides down the inner wall of the mixing chamber 1 to flush the inner wall. At the same time, the rotation of the shear head 305 agitates the water, improving the cleaning effect. This makes it easier to discharge the wastewater from the upper space into the lower space for reuse after preparation, reducing the amount of water used for cleaning and the workload of workers, making it easier to use.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
