Description

Technical Field

[0001] This utility model belongs to the field of extraction equipment technology, and specifically relates to an extraction device. Background Technology

[0002] Ginkgo biloba extract refers to the active substances extracted from ginkgo leaves, such as total ginkgo flavonoids and ginkgolides. Ginkgo biloba extract is widely used in various fields, including pharmacy, cosmetics, and the food industry. For example, in pharmacy, it is used as a natural pharmaceutical ingredient with numerous benefits, including but not limited to antioxidant, anti-inflammatory, and anti-platelet aggregation properties, thus helping to improve blood circulation and protect cardiovascular health. In cosmetics, it is widely added to skincare products. In the food industry, it is frequently used as a food additive.

[0003] Ginkgo leaves require processing through crushing, extraction, filtration, concentration, and drying. However, existing extraction devices typically only perform the extraction process. The initial crushing and subsequent filtration processes require additional equipment, which is not only cumbersome but also increases the cost of purchasing new equipment for users.

[0004] Therefore, it is necessary to provide an extraction device to address the aforementioned technical problems. Utility Model Content

At the same time, it can also collect the reaction liquid and the crushed ginkgo leaves for extraction of ginkgo leaves.

[0017] In one or more embodiments of this utility model, the fixing plate is provided with a discharge pipe, and a control valve is installed on the discharge pipe. The discharge pipe is used to discharge ginkgo leaf extract.

[0018] The filtration mechanism includes an inclined plate, which is fixedly connected to the lower side of the fixed plate and can guide the flow of the extract.

[0019] In one or more embodiments of this utility model, a plurality of filter screens are connected between the fixed plate and the inclined plate. The filter screens are used to filter the extract in order to remove impurities from the extract.

[0020] A drain pipe is installed on the inclined plate, and a filter screen is located between the unloading pipe and the drain pipe. The filtered extract is discharged from the extraction tank through the drain pipe and the outlet pipe for subsequent processing.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 6 As shown, an extraction device according to one embodiment of the present invention includes an extraction tank 1 and a processing mechanism 2.

[0033] The extraction tank 1 is connected to a reaction liquid inlet pipe 101 and a ginkgo leaf inlet 102. The reaction liquid inlet pipe 101 is used to feed the reaction liquid into the extraction tank 1, and the ginkgo leaf inlet 102 is used to feed the ginkgo leaves.

[0034] In addition, the bottom of the extraction tank 1 is connected to a liquid outlet pipe 103, through which the ginkgo leaf extract is discharged for subsequent processing.

[0035] Specifically, the reaction liquid feed pipe 101 is connected to an annular pipe 104 at one end inside the extraction tank 1. The annular pipe 104 surrounds the rotating shaft 202 and corresponds to the crushing mechanism. The annular pipe 104 has several evenly distributed through holes 1041. The reaction liquid added through the reaction liquid feed pipe 101 enters the annular pipe 104 and is discharged through the several through holes 1041. The discharged reaction liquid is evenly poured onto the crushing disc 203 and the grinding disc 205. When the reaction liquid flows through the gap between the crushing disc 203 and the grinding disc 205, it can carry away the crushed ginkgo leaves, making it less likely for the ginkgo leaves to accumulate in the gap between the crushing disc 203 and the grinding disc 205, so as to facilitate the subsequent extraction of ginkgo leaves.

[0036] In addition, the side wall of the extraction tank 1 is provided with a cleaning door 105, which corresponds to the filtration mechanism and facilitates the cleaning of several filter screens 210.

[0037] like Figures 1 to 6As shown, the processing unit 2 is installed on the extraction tank 1. The processing unit 2 is used to crush, extract and filter ginkgo leaves, thereby improving the overall functionality of the extraction tank 1. It can not only simplify the processing steps of ginkgo leaves, but also reduce the cost of purchasing equipment for users.

[0038] The processing mechanism 2 includes an electric motor 201, which is located outside the extraction tank 1 and has a rotating shaft 202 connected to it. When the electric motor 201 is running, it can drive the rotating shaft 202 to rotate.

[0039] like Figures 1 to 6 As shown, a crushing mechanism is connected to the side wall of the rotating shaft 202, which can be used to crush ginkgo leaves.

[0040] The crushing mechanism includes a crushing disc 203 connected to the side wall of a rotating shaft 202, and a plurality of cutting blades 204 embedded in the side wall of the crushing disc 203. When the motor 201 is running, the rotating shaft 202 can drive the crushing disc 203 and the cutting blades 204 to rotate. The rotating cutting blades 204 cooperate with the grinding disc 205 to cut the ginkgo leaves.

[0041] In addition, a grinding disc 205 is fixedly connected to the inner wall of the extraction tank 1, and the grinding disc 205 corresponds to the crushing disc 203. Through the cooperation of the crushing disc 203 and the grinding disc 205, the ginkgo leaves can be cut and crushed for subsequent extraction.

[0042] Specifically, the grinding disc 205 includes a cutting section and a crushing section, with a cutting blade 204 corresponding to the cutting section. The cutting blade 204 rotates in the cutting section to cut ginkgo leaves, and the crushing disc 203 cooperates with the crushing section to pulverize the ginkgo leaves.

[0043] like Figures 1 to 6 As shown, a pair of stirring plates 206 are connected to the side wall of the rotating shaft 202. The crushed ginkgo leaves and the reaction liquid will gather on the fixed plate 207. Under the stirring action of the stirring plates 206, the ginkgo leaves can react with the reaction liquid, thereby extracting the ginkgo leaves.

[0044] The extraction tank 1 is fixedly connected to a fixing plate 207 on its inner wall. The fixing plate 207 is rotatably connected to the rotating shaft 202 and is located below the grinding disc 205. The fixing plate 207 serves to stabilize the rotating shaft 202 and also collects the reaction liquid and the crushed ginkgo leaves for extraction.

[0045] In addition, a discharge pipe 208 is provided on the fixed plate 207, and a control valve is installed on the discharge pipe 208. The discharge pipe 208 is used to discharge the ginkgo leaf extract.

[0046] like Figures 1 to 6 As shown, a filtration mechanism is provided on the lower side of the stirring plate 206 to filter the ginkgo leaf extract and remove impurities from the extract.

[0047] The filtration mechanism includes an inclined plate 209, which is fixedly connected to the lower side of the fixed plate 207. The inclined plate 209 can guide the flow of the extract.

[0048] In addition, a number of filter screens 210 are connected between the fixed plate 207 and the inclined plate 209. The filter screens 210 are used to filter the extract in order to remove impurities from the extract.

[0049] Preferably, there are three filter screens 210, and the mesh ratio of the three filter screens 210 is 1:2:3, which can perform progressive filtration of ginkgo leaf extract and improve the filtration effect of ginkgo leaf extract.

[0050] Specifically, a drain pipe 211 is installed on the inclined plate 209, and a filter screen 210 is located between the discharge pipe 208 and the drain pipe 211. The filtered extract is discharged from the extraction tank 1 through the drain pipe 211 and the outlet pipe 103 for further processing.

[0051] In practical use, ginkgo leaves are put into the extraction tank 1 through the ginkgo leaf inlet 102, and the motor 201 is run. The motor 201 drives the rotating shaft 202 to rotate, which in turn drives the crushing disc 203, the cutting blade 204 and the stirring plate 206 to rotate.

[0052] When a ginkgo leaf falls into the gap between the crushing disc 203 and the grinding disc 205, the ginkgo leaf will be cut by the rotating cutting blade 204. At the same time, the ginkgo tree will be crushed by the rotating crushing disc 203 after being cut, and the crushed ginkgo leaf will fall onto the fixing plate 207.

[0053] The reaction liquid is added to the extraction tank 1 through the reaction liquid feed pipe 101. The reaction liquid enters the annular pipe 104 and is discharged through several through holes 1041. The discharged reaction liquid is evenly poured onto the crushing disc 203 and the grinding disc 205. When the reaction liquid flows through the gap between the crushing disc 203 and the grinding disc 205, it can carry away the crushed ginkgo leaves, making it less likely for the ginkgo leaves to accumulate in the gap between the crushing disc 203 and the grinding disc 205.

[0054] The reaction solution and the pulverized ginkgo leaves will gather on the fixed plate 207. Under the stirring action of the stirring plate 206, the ginkgo leaves can react with the reaction solution, thereby extracting the ginkgo leaves.

[0055] After the ginkgo leaf extraction is completed, the control valve on the discharge pipe 208 is opened, and the ginkgo leaf extract flows through the discharge pipe 208. Under the guidance of the inclined plate 209, it passes through multiple filter screens 210 in sequence. The filter screens 210 can be used to filter the ginkgo leaf extract and remove impurities from it.

[0056] The filtered ginkgo leaf extract is discharged from the extraction tank 1 through the drain pipe 211 and the outlet pipe 103 for further processing.

[0057] 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.
