Description

Technical Field

[0001] The utility model belongs to the technical field of forsythia leaf extraction, and particularly relates to a forsythia leaf extraction device. Background Art

[0002] Components such as phillyrin and forsythoside in forsythia leaves have medicinal values. Workers will extract forsythia leaves to extract components such as phillyrin and forsythoside in the forsythia leaves. When using the solvent extraction method to extract forsythia leaves, the forsythia leaves need to be immersed in the extraction solvent, and the extraction solvent and the forsythia leaves are stirred. After the extraction is completed, the workers also need to filter and separate the forsythia leaves and the extraction solvent. At present, the extraction barrel filters the forsythia leaves by installing a filter net. However, as the extraction liquid flows out, a large number of adjacent leaves will fit together, and part of the extraction solvent will remain between the fitted forsythia leaves. The remaining extraction liquid cannot be discharged in a short time. Using a centrifuge or a negative pressure filter to filter the remaining extraction liquid in the forsythia leaves will greatly increase the equipment cost, and it is not applicable for small-scale processing. When the forsythia leaves are taken out and placed in an additional container for static filtration, a small amount of the filtered extraction liquid will still adhere to the inner wall of the container, causing additional losses. Content of the Utility Model

[0003] The utility model provides a forsythia leaf extraction device, which has the characteristic of being able to fully separate the extraction liquid and the forsythia leaf raw material at a lower cost.

[0004] The utility model provides the following technical solution: a forsythia leaf extraction device, including a forsythia leaf solvent extraction barrel, a forsythia leaf leakage net barrel is detachably connected inside the forsythia leaf solvent extraction barrel, a stacking limiting ring is fixedly connected to the top end of the forsythia leaf leakage net barrel, the diameter of the forsythia leaf leakage net barrel matches the inner diameter of the stacking limiting ring, an "L"-shaped connecting rod is arranged outside the forsythia leaf leakage net barrel, an edge stirring plate is fixedly connected to the outer wall of the vertical rod of the "L"-shaped connecting rod, a bottom stirring plate is fixedly connected to the outer wall of the horizontal rod of the "L"-shaped connecting rod, a driven gear ring is fixedly connected to the outer wall of the "L"-shaped connecting rod, and a driving gear is meshed with one side of the driven gear ring.

[0005] Wherein, a limiting groove block is fixedly connected to the inner wall of the bottom end of the forsythia leaf solvent extraction barrel, a polygonal limiting insertion block is fixedly connected to the bottom end of the forsythia leaf leakage net barrel, and the polygonal limiting insertion block is inserted into the limiting groove block.

[0006] Wherein, a limiting connecting rod is fixedly connected to one side of the horizontal rod of the "L"-shaped connecting rod, and the limiting connecting rod is rotatably connected to the inner wall of the limiting groove block.

[0007] Wherein, a driving motor is installed at the bottom end of the driving gear, and the driving motor is installed on the side wall of the forsythia leaf solvent extraction barrel.

[0008] Wherein, a body protective housing is provided outside the driven gear ring, the driving gear and the driving motor, and the opening position at the top of the body protective housing corresponds to the position of the stacking limiting ring.

[0009] The beneficial effects of the present utility model are as follows: By means of the forsythia leaf leakage net barrel, the diffusion range of forsythia leaves is restricted, and the agitation of the extraction solvent in the forsythia leaf solvent extraction barrel by the cooperation of the driving gear with the "L"-shaped connecting rod, the edge stirring plate and the bottom stirring plate near the inner wall of the forsythia leaf solvent extraction barrel can accelerate the full mixing of the forsythia leaves and the extraction solvent while making way for the forsythia leaf leakage net barrel and the space above the forsythia leaf leakage net barrel. With the dimensional cooperation between the forsythia leaf leakage net barrel and the stacking limiting ring, two forsythia leaf leakage net barrels can be stacked and placed at the central position of the forsythia leaf solvent extraction barrel, so that during the extraction process of the forsythia leaves by the device, the previously extracted forsythia leaves can be leaked, without the need to additionally purchase a filtering device to filter the solvent extract attached to the forsythia leaves, and without the need to pour the filtered solvent extract between containers, avoiding the residue on the container wall, and enabling the full separation of the extract and the forsythia leaf raw material at a lower cost.

Detailed Embodiments

[0015] Please refer to Figures 1 - 3, the present utility model provides the following technical solutions: A forsythia leaf extraction device includes a forsythia leaf solvent extraction barrel 1, and a detachable forsythia leaf leakage net barrel 2 is arranged inside the forsythia leaf solvent extraction barrel 1. A stacking limit ring 21 is fixedly connected to the top end of the forsythia leaf leakage net barrel 2, and the diameter of the forsythia leaf leakage net barrel 2 matches the inner diameter of the stacking limit ring 21. An "L"-shaped connecting rod 3 is arranged outside the forsythia leaf leakage net barrel 2. An edge stirring plate 31 is fixedly connected to the outer wall of the vertical rod of the "L"-shaped connecting rod 3, a bottom stirring plate 32 is fixedly connected to the outer wall of the horizontal rod of the "L"-shaped connecting rod 3, and a driven gear ring 33 is fixedly connected to the outer wall of the "L"-shaped connecting rod 3. A driving gear 4 is meshed with one side of the driven gear ring 33.

[0016] In this implementation: The staff loads the forsythia leaves to be extracted into the forsythia leaf leakage mesh barrel 2, and then installs the forsythia leaf leakage mesh barrel 2 in the forsythia leaf solvent extraction barrel 1. The polygonal limit insertion block 22 is inserted into the limit groove block 11 in a matching position. Then, the staff adds the solvent extraction solution into the forsythia leaf solvent extraction barrel 1. After the raw materials are added, the controller controls the driving gear 4 and the driving motor 41 to rotate. By means of the driving gear 4, the driven gear ring 33 is driven to rotate, thereby driving the "L"-shaped connecting rod 3 to rotate, and then driving the edge stirring plate 31 and the bottom stirring plate 32 to rotate. During the rotation of the edge stirring plate 31 and the bottom stirring plate 32, the solvent extraction solution in the forsythia leaf solvent extraction barrel 1 is driven to move, and with the help of the edge stirring plate 31 and the bottom stirring plate 32 obtaining an inclination angle, the solvent extraction solution outside the forsythia leaf leakage mesh barrel 2 can be squeezed and conveyed into the forsythia leaf leakage mesh barrel 2 to complete the circulating exchange of the solvent extraction solution inside and outside the forsythia leaf leakage mesh barrel 2, accelerating the full mixing of the forsythia leaves and the extraction solvent. During the solvent extraction process, the forsythia leaf leakage mesh barrel 2 can be used to limit the diffusion range of the forsythia leaves, so that after the extraction is completed, the staff can directly lift the forsythia leaf leakage mesh barrel 2 upward to quickly take out the forsythia leaves from the forsythia leaf solvent extraction barrel 1. Moreover, the "L"-shaped connecting rod 3, the edge stirring plate 31, and the bottom stirring plate 32 are close to the inner wall position of the forsythia leaf solvent extraction barrel 1, which can make way for the forsythia leaf leakage mesh barrel 2 and the space above the forsythia leaf leakage mesh barrel 2. With the dimensional matching of the forsythia leaf leakage mesh barrel 2 and the stacking limit ring 21, two forsythia leaf leakage mesh barrels 2 can be stacked and placed at the central position of the forsythia leaf solvent extraction barrel 1. When extracting the forsythia leaves of the next batch, the staff can stack the forsythia leaves and the forsythia leaf leakage mesh barrel 2 extracted in the previous batch on the top of the forsythia leaf leakage mesh barrel 2 that is currently participating in the extraction, so that during the extraction of the forsythia leaves by the device, the forsythia leaves extracted previously can be leaked. There is no need to additionally purchase a filtering device to filter the solvent extraction solution attached to the forsythia leaves, and there is no need to pour the filtered solvent extraction solution between containers, simplifying the operation during the filtration of the solvent extraction solution, and enabling the full separation of the extraction solution and the forsythia leaf raw materials at a lower cost. After the leakage is completed, the staff removes the forsythia leaf leakage mesh barrel 2 located on the upper layer and cleans the forsythia leaves in the forsythia leaf leakage mesh barrel 2 for use in the next extraction. One device cooperates with two forsythia leaf leakage mesh barrels 2, and the two forsythia leaf leakage mesh barrels 2 are used repeatedly and alternately.

[0017] At the inner bottom wall of the forsythia leaf solvent extraction barrel 1, there is a fixed connection with a limit groove block 11. At the bottom of the forsythia leaf leakage net barrel 2, there is a fixed connection with a polygonal limit insertion block 22, and the polygonal limit insertion block 22 is inserted into the limit groove block 11. By setting the limit groove block 11, the forsythia leaf leakage net barrel 2 can be supported and the "L"-shaped connecting rod 3 can be limited. At the top of the limit groove block 11, there is a groove with dimensions matching those of the polygonal limit insertion block 22. The groove is polygonal, which can limit the forsythia leaf leakage net barrel 2 so that the forsythia leaf leakage net barrel 2 can remain stable during the liquid stirring process.

[0018] On one side of the crossbar of the "L"-shaped connecting rod 3, there is a fixed connection with a limit connecting rod 34, and the limit connecting rod 34 is rotatably connected to the inner wall of the limit groove block 11. On the side wall of the limit groove block 11, there is a relief groove ring with dimensions matching those of the limit connecting rod 34. Through the annular relief groove, the limit connecting rod 34 is given way so that the limit connecting rod 34 can rotate in the limit groove block 11.

[0019] At the bottom of the driving gear 4, there is an installation of a driving motor 41, and the driving motor 41 is installed on the side wall of the forsythia leaf solvent extraction barrel 1. By setting the driving motor 41, the driving gear 4 can be driven to rotate. The driving motor 41 is controlled to open and close through a control device. The driving motor 41 is connected to the power supply through an electric wire. The controller and power connection wires of the device can be installed in the space below the driving motor 41 and protected by the body protective shell 5 to avoid being directly exposed and damaged.

[0020] Outside the driven gear ring 33, the driving gear 4 and the driving motor 41, there is a body protective shell 5. The opening position at the top of the body protective shell 5 corresponds to the position of the stacking limit ring 21. By setting the body protective shell 5, the driven gear ring 33, the driving gear 4 and the driving motor 41 can be shielded and protected, improving the safety during the use of the device.

[0021] Working principle and usage process of the utility model: The staff loads forsythia leaves to be extracted into the forsythia leaf leakage net barrel 2, and then installs the forsythia leaf leakage net barrel 2 in the forsythia leaf solvent extraction barrel 1. The polygonal limit insertion block 22 is inserted into the limit groove block 11 in a corresponding position. Then, the staff adds solvent extract to the forsythia leaf solvent extraction barrel 1. After the raw material addition is completed, the controller controls the driving gear 4 and the driving motor 41 to rotate. By means of the driving gear 4, the driven gear ring 33 is driven to rotate, thereby driving the "L"-shaped connecting rod 3 to rotate, and then driving the edge stirring plate 31 and the bottom stirring plate 32 to rotate. During the rotation of the edge stirring plate 31 and the bottom stirring plate 32, the solvent extract in the forsythia leaf solvent extraction barrel 1 is driven to move, and with the help of the edge stirring plate 31 and the bottom stirring plate 32 obtaining an inclination angle, the solvent extract outside the forsythia leaf leakage net barrel 2 can be squeezed and conveyed into the forsythia leaf leakage net barrel 2 to complete the cyclic exchange of the solvent extract inside and outside the forsythia leaf leakage net barrel 2, accelerating the full mixing of forsythia leaves and extraction solvent. During the solvent extraction process, the staff stacks the forsythia leaves and the forsythia leaf leakage net barrel 2 extracted in the previous batch on the top of the forsythia leaf leakage net barrel 2 participating in the extraction. During the extraction of forsythia leaves, the forsythia leaves extracted previously are leaked. After the leakage is completed, the staff removes the forsythia leaf leakage net barrel 2 located on the upper layer and cleans the forsythia leaves in the forsythia leaf leakage net barrel 2 for the next extraction use. One device cooperates with two forsythia leaf leakage net barrels 2, and the two forsythia leaf leakage net barrels 2 are used repeatedly and alternately.
