Description

Technical Field

[0001] This utility model relates to the field of extraction tank technology, specifically to an extraction device for grape seed extract. Background Technology

[0002] Grape seed extract is a natural product extracted from grape seeds, rich in various active ingredients such as proanthocyanidins, catechins, flavonoids, vitamin E, and polyphenols. Grape seed extract is widely used in health supplements, food additives, cosmetics, and the medical field. The core equipment for grape seed extract extraction is the extraction tank, commonly a conical extraction tank. This tank features a conical design with a sharp bottom and a wide top, facilitating the separation of liquids and solids and promoting fluid flow. It has a feed inlet at the top for adding raw materials and solvents, and an internal stirring device to ensure thorough mixing of the raw materials and solvents, thus improving extraction efficiency.

[0003] Chinese patent CN208212575U discloses a multifunctional traditional Chinese medicine extraction tank. A telescopic feeding cylinder is connected to the feed port of the extraction tank. A cylinder is mounted on the side wall of the telescopic feeding cylinder. A stirring motor is mounted at the center of the top of the extraction tank, and the stirring motor is connected to a reducer. The reducer is connected to a drive shaft placed inside the extraction tank via a coupling. The drive shaft is equipped with a blade-type stirring paddle. A solvent and tap water inlet are located on the upper part of the side wall of the extraction tank, while a steam outlet and a steam inlet are located on the lower part of the side wall. This design not only allows the effective components of the medicine to dissolve better in the solvent, but also separates the residue into several parts, making residue removal easier. It also facilitates the collection of volatile oils generated during the extraction process, representing an innovation in traditional Chinese medicine extraction devices.

[0004] However, the above-disclosed technical solutions have the following shortcomings: In order to ensure the mixing effect, the stirring paddle needs to have a certain length, usually extending to a position close to the inner wall. For the positive conical extraction tank, the bottom size gradually decreases. The stirring paddle of this structure cannot be taken out from the bottom, and the top is usually not openable. This makes it impossible to remove the stirring paddle for thorough cleaning or to change its style. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the stirring paddle cannot be easily removed, and to propose an extraction device for grape seed extract.

[0011] The second stirring plate is rotatably mounted at the end of the first stirring plate. When the second stirring plate is rotated upward to its maximum angle, it is in a horizontal state. A limiting plate is provided on the first stirring plate, and the limiting plate abuts against the second stirring plate in the upper stirring mechanism to keep it in a horizontal state.

[0012] And a limiting component is set at the bottom of the main shaft, which abuts against the sliding ring in the lowest set of stirring mechanisms.

[0013] Preferably, the top of the extraction tank is equipped with a feed inlet, an observation window, a liquid inlet pipe, and a pressure relief valve, and a feed cover is installed on the feed inlet.

[0014] Preferably, the pneumatic mechanism includes two cylinder mounting brackets symmetrically arranged on the outer wall of the bottom of the extraction tank, a main cylinder and an auxiliary cylinder rotatably arranged on the two cylinder mounting brackets, a sealing support bracket and a reinforcing support bracket located directly below the two cylinder mounting brackets and connected to the outer wall of the extraction tank, a bottom support plate rotatably connected to the sealing support bracket, and a reinforcing sealing bracket rotatably connected to the reinforcing support bracket.

[0018] Preferably, the second stirring plate on the stirring mechanism located in the conical space at the bottom of the extraction tank is removed.

[0019] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: when it is necessary to thoroughly clean the stirring mechanism or change the style of the stirring structure, first unscrew the two limit nuts, and then move the stirring mechanism outward from the bottom in sequence. After the stirring structure below is removed, the second stirring plate can be flipped downward, thereby reducing the size and passing smoothly through the bottom discharge port of the extraction tank. It can quickly complete the disassembly and assembly of multiple stirring structures and is convenient to use. Attached Figure Description

[0025] Example 1

[0026] like Figures 1-4 As shown, the present invention proposes an extraction device for grape seed extract, comprising an extraction tank 1, a support mechanism 2 on the outer wall of the extraction tank 1 to detach it from the ground, an inlet, an observation window 4, a liquid inlet pipe 5, and a pressure relief valve 6 on the top of the extraction tank 1, an inlet cover 3 on the inlet, the inlet cover 3 being locked to the top of the extraction tank 1 by multiple spring clips, allowing for quick installation and removal of the inlet cover 3, a conical bottom of the extraction tank 1 with an outlet, a rotatable outlet sealing plate 7 at the bottom of the extraction tank 1 to close the outlet, and a pneumatic mechanism for opening and closing the outlet sealing plate 7, the support mechanism 2 including four fixed frames on the outer wall of the extraction tank 1, support columns vertically mounted at the bottom of the four fixed frames, and reinforcing horizontal plates connecting the support columns, and multiple stirring mechanisms arranged side by side on the main shaft 18, the stirring mechanisms including:

[0027] A motor mounting base 16 is set on the top outer wall of the extraction tank 1. A motor 17 is set on the motor mounting base 16. The output shaft of the motor 17 is connected to a main shaft 18, and the main shaft 18 is inserted into the extraction tank 1.

[0028] A limiting ring 19 is set on the main shaft 18, and the limiting ring 19 is located inside the extraction tank 1 near the top.

[0029] The sliding ring 20 is slidably sleeved on the main shaft 18 in the vertical direction, and the sliding ring 20 is vertically provided with a partition rod 21;

[0030] The first stirring plate 22 is horizontally arranged on the outer wall of the sliding ring 20. The length of the first stirring plate 22 is less than the radius of the discharge port of the extraction tank 1, and it can be moved directly downward from the discharge port.

[0031] The second stirring plate 23 is rotatably disposed at the end of the first stirring plate 22. When the second stirring plate 23 is rotated upward to the maximum angle, it is in a horizontal state. A limiting plate 24 is provided on the first stirring plate 22. The limiting plate 24 abuts against the second stirring plate 23 in the upper stirring mechanism to keep it in a horizontal state.

[0032] And a limiting component is set at the bottom of the main shaft 18, which abuts against the sliding ring 20 in the lowest set of stirring mechanisms.

[0033] Example 2

[0034] like Figure 2 As shown, this utility model proposes an extraction device for grape seed extract. Compared with Embodiment 1, this embodiment details the structure of the pneumatic mechanism.

[0035] The pneumatic mechanism includes two cylinder mounting brackets 9 symmetrically arranged on the outer wall of the bottom of the extraction tank 1, a main cylinder 10 and an auxiliary cylinder 13 rotatably mounted on the two cylinder mounting brackets 9, a sealing support bracket 11 and a reinforcing support bracket 15 located directly below the two cylinder mounting brackets 9 and connected to the outer wall of the extraction tank 1, a bottom support plate 12 rotatably connected to the sealing support bracket 11, and a reinforcing sealing bracket 14 rotatably connected to the reinforcing support bracket 15. The telescopic end of the bottom of the main cylinder 10 is connected to the end of the bottom support plate 12. The auxiliary cylinder 13 is rotatably connected to the bottom telescopic end of the auxiliary cylinder 13 and the reinforcing sealing frame 14. When sealing is required, the main cylinder 10 extends, pushing the bottom support plate 12 to rotate clockwise. The bottom support plate 12 pushes the discharge sealing plate 7 to flip upward and press against the discharge port. Then, the auxiliary cylinder 13 extends, pushing the reinforcing sealing frame 14 to rotate counterclockwise. The reinforcing sealing frame 14 further squeezes the discharge sealing plate 7 from the edge upward to complete the seal. When the discharge port needs to be opened, both the main cylinder 10 and the auxiliary cylinder 13 retract.

[0036] Example 3

[0037] like Figures 3-4As shown, this utility model proposes an extraction device for grape seed extract. Compared with Embodiment 1, this embodiment details the structure of the stirring mechanism.

[0038] A limiting strip is vertically installed on the outer wall of the main shaft 18, and a sliding groove is installed on the inner wall of the sliding ring 20. The limiting strip passes through the sliding groove, allowing the sliding ring 20 to move up and down, but not to rotate relative to the main shaft 18. When the main shaft 18 rotates, it drives the sliding ring 20 to rotate. A strip groove 27 is provided at the bottom of the end face of the first stirring plate 22. A pin 26 is longitudinally and rotatably installed in the strip groove 27. The end of the second stirring plate 23 is connected to the pin 26. When the second stirring plate 23 rotates to a horizontal position, it abuts against the top of the strip groove 27, thereby limiting the second stirring plate 23. The limiting components are multiple limiting nuts 25. The outer peripheral wall of the bottom of the main shaft 18 and the limiting nuts 25 are threadedly engaged. The limiting nuts 25 abut against the sliding ring 20 from below. In this embodiment, two limiting nuts 25 are provided. Due to the size limitation of the bottom of the extraction tank 1, the second stirring plate 23 located on the stirring mechanism in the conical space at the bottom of the extraction tank 1 is removed, and stirring is completed by the first stirring plate 22.

[0039] In summary, when in use, this utility model employs a parallel arrangement of stirring mechanisms. The separator rod 21 abuts against the limiting ring 19, or against the bottom of the sliding ring 20 in the previous stirring mechanism, achieving equidistant separation of multiple stirring mechanisms. Two limiting nuts 25 secure the mechanism from the bottom, and a limiting plate 24 abuts against the bottom of the second stirring plate 23, ensuring the second stirring plate 23 is horizontal. At this point, the first stirring plate 22 and the second stirring plate 23 are aligned, maximizing the stirring range. To thoroughly clean the stirring mechanism or change its structure, first unscrew the two limiting nuts 25, then remove the stirring mechanism from the bottom outwards. After removing the lower stirring structure, the second stirring plate 23 can be flipped downwards, reducing its size and allowing it to pass smoothly through the bottom outlet of the extraction tank 1. This allows for quick assembly and disassembly of multiple stirring structures, making it convenient to use.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
