Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, and in particular to an ultrasonic circulating extraction device for moss antibacterial agents. Background Technology

[0002] Bryophytes, as a potential natural antibacterial resource, possess secondary metabolites such as phenols, flavonoids, and terpenes that exhibit excellent antibacterial activity. To efficiently and at low temperatures extract these heat-sensitive active ingredients, ultrasonic extraction technology has been widely applied in this field. Utilizing cavitation and mechanical vibration, ultrasound can effectively break down bryophyte cell walls, accelerate the dissolution of active ingredients, and significantly improve extraction efficiency and yield.

[0003] To further improve the uniformity and efficiency of extraction, those skilled in the art typically introduce a circulation system into the ultrasonic extraction device, forming an ultrasonic circulating extraction device. This device uses a circulating pump to continuously circulate the mixture of extraction solvent and moss material between the extraction tank and the storage tank, aiming to ensure that the material undergoes uniform ultrasonic treatment and maintain a dynamic equilibrium of concentration within the extraction system.

[0004] However, existing ultrasonic circulating extraction devices have a significant technical drawback when performing circulating extraction operations on raw materials such as moss that are rich in fiber and pectin and are prone to clumping: the circulating device is very easy to be clogged by the residue generated during the extraction process.

[0005] During the circulating operation, the moss material continuously broken down by ultrasound forms a large amount of fine fibrous residue and viscous substances. When these substances flow with the liquid to key components such as the circulation pipeline, pump body, and filter, they are prone to adhering, entanglement, and accumulation, ultimately leading to damage to the circulation device and affecting the equipment's extraction efficiency.

[0006] Therefore, there is an urgent need for a technical solution that can effectively address the problem of slag blockage and ensure that the ultrasonic circulating extraction device can operate stably, continuously, and efficiently when processing materials that are prone to blockage, such as moss. Utility Model Content

[0007] To address the technical problem that the circulation device in the ultrasonic circulation extraction device for moss antibacterial agents is easily clogged by the residue generated during the extraction process, this utility model provides an ultrasonic circulation extraction device for moss antibacterial agents.

[0008] This utility model is achieved using the following technical solution: an ultrasonic circulating extraction device for moss antibacterial agents, comprising:

[0009] The sedimentation chamber and the stirring chamber are fixedly connected from bottom to top. The outer wall of the sedimentation chamber and the stirring chamber are connected by a support. A valve port is provided at the connection between the sedimentation chamber and the stirring chamber. A sealing plug is threaded to the bottom of the sedimentation chamber. A circulation mechanism is provided at the external connection between the sedimentation chamber and the stirring chamber. An ultrasonic oscillator is provided at the bottom of the inner wall of the stirring chamber near the valve port. An agitation mechanism is provided inside the stirring chamber. A feed port is connected to the top of the stirring chamber.

[0010] The circulation mechanism is equipped with a filter at the inlet of the sedimentation chamber. This filter is used to extract the settled liquid and treat the inlet of the circulation mechanism.

[0011] As a further improvement to the above solution, the stirring mechanism includes a motor coaxially fixed to the top of the stirring chamber. The output end of the motor is located inside the stirring chamber and coaxially fixed to a rotating shaft. A connecting block is fixedly connected to the rotating shaft. Crossbars are symmetrically fixedly connected to both sides of the connecting block. A stirring plate is rotatably connected to both sides of the crossbars.

[0012] As a further improvement to the above scheme, the stirring plate is evenly provided with several sets of inclined slits along its own length, and a central opening is provided in the middle of each set of inclined slits and near the two sets of inclined slits. Chamfers are provided at both the inclined slits and the central openings.

[0013] As a further improvement to the above scheme, the circulation mechanism includes a connecting pipe with its inlet located directly above the sealing plug. The connecting pipe passes through the outer wall of the sedimentation chamber and enters from above the outer wall of the stirring chamber. A circulation pump is installed at the connecting pipe.

[0014] As a further improvement to the above solution, a filter head is fixedly connected to the drain outlet of the connecting pipe. A rotating rod is coaxially rotatably connected to the bottom end of the filter head. The bottom end of the rotating rod passes through the filter head and is symmetrically fixedly connected to an arc-shaped plate. The inner ends of the two arc-shaped plates are attached to the outer wall of the filter head.

[0015] As a further improvement to the above scheme, the rotating rod is fixedly connected to the outer wall of the connecting pipe with a spiral rotating blade.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (i) The circulation mechanism in this utility model is equipped with a filter cleaning component at the inlet of the sedimentation chamber; when the circulation pump is working, the fluid drives the rotating blades to rotate, which drives the arc plate to continuously scrape and clean the outer wall of the filter head, preventing moss residue from adhering and accumulating, avoiding blockage of the pipeline and pump body, thereby ensuring the continuity and stability of the circulation extraction operation and reducing the risk of equipment damage.

[0018] (ii) The stirring mechanism in this utility model adopts a rotatable stirring plate, which unfolds horizontally under the action of centrifugal force to increase the stirring range; the design of the inclined and central openings on the stirring plate intensifies the fluid disturbance, and in combination with the cavitation effect of the ultrasonic oscillator, accelerates the breaking of moss cells and the dissolution of effective components, thereby improving the extraction efficiency and yield.

[0019] (III) The device of this utility model adopts a design in which the sedimentation chamber and the stirring chamber are connected vertically. The fluid flow is controlled by the valve port, and the sealing plug facilitates the final drainage and slag removal.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figures 1-4 An ultrasonic circulating extraction device for moss antibacterial agents according to this embodiment includes:

[0029] The sedimentation chamber 1 and the stirring chamber 2 are fixedly connected from bottom to top. The outer walls of the sedimentation chamber 1 and the stirring chamber 2 are connected by a support 3. A valve port 6 is provided at the connection between the sedimentation chamber 1 and the stirring chamber 2. A sealing plug 5 is threaded to the bottom of the sedimentation chamber 1. A circulation mechanism is provided at the external connection between the sedimentation chamber 1 and the stirring chamber 2. An ultrasonic oscillator is provided at the bottom of the inner wall of the stirring chamber 2 near the valve port 6. An agitation mechanism is provided inside the stirring chamber 2. A feed port 4 is connected to the top of the stirring chamber 2.

[0030] The circulation mechanism is equipped with a filter cleaning component at the inlet of the sedimentation chamber 1. This component is used to extract the settled liquid and to treat the inlet of the circulation mechanism.

[0031] See Figures 1-4 The sedimentation chamber 1 and the stirring chamber 2 are connected to each other, with a funnel-shaped arrangement in the center connecting two directions. The valve port 6 is located in the middle of the sedimentation chamber 1 and the stirring chamber 2, which facilitates the stirring mechanism and the ultrasonic oscillator to break up the bryophytes and accelerate the dissolution of the effective components.

[0032] After the initial crushing and filtration is completed, first turn valve 6 to release the closed state between sedimentation chamber 1 and stirring chamber 2, so that the fluid in stirring chamber 2 can enter sedimentation chamber 1. After the fluid has flowed out sufficiently, turn valve 6 again to close sedimentation chamber 1 and stirring chamber 2. Then, the fluid in sedimentation chamber 1 can enter stirring chamber 2 to achieve cyclic extraction.

[0033] The stirring mechanism includes a motor 7 coaxially fixed to the top of the stirring chamber 2. The output end of the motor 7 is located inside the stirring chamber 2 and coaxially fixed to a rotating shaft 8. A connecting block 9 is fixedly connected to the rotating shaft 8. A crossbar 10 is symmetrically fixedly connected to both sides of the connecting block 9. A stirring plate 11 is rotatably connected to both sides of the crossbar 10.

[0034] See Figures 1-3 The two stirring plates 11 can be stably vertical under gravity, and after the motor 7 is started, the two stirring plates 11 are made horizontal with the crossbar 10 by centrifugal force, which can effectively improve the stirring effect and range.

[0035] The stirring plate 11 has several sets of inclined slits 12 evenly distributed along its length, and a central opening 13 is provided in the middle of each set of inclined slits 12 and at the adjacent positions of two sets of inclined slits 12. Chamfers are provided at both the inclined slits 12 and the central opening 13.

[0036] See Figure 3 As the rotation occurs, the centrifugal force pulls the two stirring plates 11 to a horizontal position, allowing the inclined opening 12 and the central opening 13 to directly disturb the fluid in the stirring chamber 2 as the rotation proceeds. The guidance of the inclined opening 12 and the central opening 13 further intensifies the disturbance of the fluid.

[0037] The circulation mechanism includes a connecting pipe 14, the inlet of which is located directly above the sealing plug 5. The connecting pipe 14 passes through the outer wall of the sedimentation chamber 1 and enters from above the outer wall of the stirring chamber 2. A circulation pump is installed at the connecting pipe 14.

[0038] See Figures 1-2 After the broken liquid enters the sedimentation chamber 1, it can be pumped back into the stirring chamber 2 by a circulation pump to achieve cyclic extraction.

[0039] A filter head 15 is fixedly connected to the drain outlet of the connecting pipe 14. A rotating rod 16 is coaxially rotatably connected to the bottom end of the filter head 15. The bottom end of the rotating rod 16 passes through the filter head 15 and is symmetrically fixedly connected to an arc plate 17. The inner ends of the two arc plates 17 are attached to the outer wall of the filter head 15.

[0040] See Figure 4 The sludge in the sedimentation chamber 1 can be filtered using the filter head 15.

[0041] The rotating rod 16 is fixedly connected to the outer wall of the connecting pipe 14 with a spiral rotating blade 18.

[0042] See Figure 4 The circulating pump draws liquid from the filter head 15 and drives the rotating blades 18 to rotate, which in turn drives the arc plate 17 to scrape and clean the filter head 15, thus preventing the filter head 15 from becoming clogged.

[0043] The implementation principle of the ultrasonic circulation extraction device for moss antibacterial agents in this application embodiment is as follows:

[0044] The valve port 6 needs to ensure that the sedimentation chamber 1 and the stirring chamber 2 are in a closed state. Then, the moss to be extracted is placed at the feed port 4, and a suitable solvent is selected according to the polarity of the antibacterial components of the moss. The ultrasonic oscillator and motor 7 are started. As the rotating shaft 8 drives the crossbar 10 to rotate, the stirring plate 11 is driven by centrifugal force to operate, further accelerating the mixing and extraction of the liquid.

[0045] After the initial extraction is completed, the extracted liquid is released into the sedimentation chamber 1 by rotating valve port 6. After initial sedimentation / directly starting the circulation pump, the liquid can enter the connecting pipe 14 through the filter head 15 and enter the stirring chamber 2. As the liquid enters the connecting pipe 14, it can drive the rotating blade 18 to drive the arc plate 17 to rotate synchronously and clean the outer wall of the filter head 15.

[0046] When the extraction operation is completed, the liquid can be released by opening the sealing plug at point 5. Specifically, the liquid can be fully introduced into the stirring chamber 2 and then the residue can be removed.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
