Description

Technical Field

[0001] The present application relates to the technical field of extraction equipment, and in particular to a plant liquid extraction device. Background Art

[0002] Plant extracts are products made from plants, which are extracted and separated through physical and chemical processes to obtain one or more active ingredients from plants without changing the structure of the active ingredients. At present, plant extracts can be used in the pharmaceutical industry, food industry, health industry, beauty industry and other industries, but the directly obtained plant extracts cannot be used directly. Some plant extracts even contain toxic substances. After various tests, the plant extracts need to be purified before they can be used. Extraction is one of the methods.

[0003] For example, a Chinese patent document with publication number CN213698891U discloses a plant material extraction device that is convenient for solid-liquid separation, including a housing, gears and stirring plates. A first fixed plate is installed inside the housing, and a connecting rod is connected to the inner side of the first fixed plate. The gear is installed above the connecting rod, and a limiting plate is installed above the gear. The stirring plate is installed above the limiting plate, and a stirring rod is connected above the stirring plate.

[0004] In the above-mentioned related technologies, water and plant raw materials are added into an extraction barrel, and then the extraction barrel is heated by a heating tube on the barrel wall. During the heating process, the plant extract will evaporate, and the evaporated plant extract will be discharged from the exhaust pipe of the extraction barrel, and finally condensed to obtain the plant extract; however, during the heating process, since the plant raw materials are solid and after being mixed in water, it is difficult to stir the materials by stirring alone, which will cause the materials to be heated unevenly in the extraction barrel, thereby reducing the extraction speed of the plant extract.

A plurality of stirring members 12 are provided, and the plurality of stirring members 12 are arranged at intervals along the length direction of the stirring shaft 11. In this embodiment, three stirring members 12 are provided. When the driving assembly 2 drives the stirring shaft 11 to rotate, the stirring shaft 11 can drive the three stirring members 12 to rotate at the same time, and then stir the plant material in the extraction barrel 02.

[0043] Reference Figures 3 to 7 , a rotating assembly 6 is arranged on the stirring shaft 11, and the rotating assembly 6 is used to drive the adjusting assembly 3 and the stirring member 12 arranged on the adjusting assembly 3 to rotate. In the initial state, the first stirring plate 121 and the second stirring plate 122 are arranged vertically. At this time, when stirring the material, the contact area between the first stirring plate 121 and the second stirring plate 122 and the material is the largest, so that it is convenient to stir the material in the extraction barrel 02. When it is necessary to exchange the position of the material, the adjusting assembly 3, the first stirring plate 121 and the second stirring plate 122 are driven to rotate by the rotating assembly 6, so that the first stirring plate 121 and the second stirring plate 122 are rotated to a horizontal state, and then in the process of the first stirring plate 121 moving upward, more material can be pushed to move, and then more material can be exchanged, so that the material in the extraction barrel 02 can be heated faster and more evenly.

[0044] Reference Figures 3 to 7The rotating assembly 6 includes a rotating shaft 61 rotatably connected to the stirring shaft 11, a rotating rod 62 fixed on the rotating shaft 61, a torsion spring 63 sleeved on the rotating shaft 61, a moving rod 64 slidably connected to the stirring shaft 11, and a driving shaft 65 rotatably connected to the moving rod 64.

One end of the torsion spring 63 is fixed on the rotating shaft 61, and the other end is fixed on the stirring shaft 11. The torsion spring 63 is used to make the first adjusting block 31, the second adjusting block 32, the first stirring plate 121 and the second stirring plate 122 in a vertical state. Then, when the first stirring plate 121 and the second stirring plate 122 need to be rotated, the moving rod 64 is directly slid upward, and the moving rod 64 drives the driving shaft 65 to move. At this time, the driving shaft 65 drives the rotating rod 62 to drive the rotating shaft 61 to rotate, thereby achieving the purpose of adjusting the position of the first stirring plate 121 and the second stirring plate 122.

[0045] In this embodiment, a connecting block is fixedly installed on the first adjusting block 31, and a connecting groove is opened on the second adjusting block 32. When the connecting block is in the connecting groove, when the rotating shaft 61 drives the second adjusting block 32 to rotate, the second adjusting block 32 can push the first adjusting block 31 to rotate as well. When the first adjusting block 31 and the second adjusting block 32 are both rotated to a horizontal state, the first adjusting block 31 is arranged above the second adjusting block 32, and the first adjusting block 31 and the moving block 33 are connected under the action of the linkage assembly 7. Finally, the first adjusting block 31 and the first stirring plate 121 arranged on the first adjusting block 31 are driven to move upward through the adjusting screw 34.

[0046] Reference Figures 3 to 7 The linkage assembly 7 includes a first linkage rod 71 fixed on the first adjustment block 31, a second linkage rod 72, and a first linkage groove 73 and a second linkage groove 74 provided on the moving block 33. The first linkage groove 73 and the second linkage groove 74 are arranged in an arc structure, and the center of the circle where the first linkage groove 73 and the second linkage groove 74 are located coincides with the center of the circle of the rotating shaft 61. The opening of the first linkage groove 73 is arranged upward, and the opening of the second linkage groove 74 is arranged downward, and the first linkage groove 73 and the second linkage groove 74 do not penetrate the moving block 33.

The movable rod 71 abuts against the bottom wall of the first linkage groove 73, and the second linkage rod 72 abuts against the top wall of the second linkage groove 74. Then, when the adjusting screw 34 drives the moving block 33 to move upward, the moving block 33 will push the first linkage rod 71 to move, and the first adjusting block 31 is driven to move upward by the first linkage rod 71. When the adjusting screw 34 drives the moving block 33 to move downward, the moving block 33 will push the second linkage rod 72 to move downward, and then under the action of the linkage assembly 7, the first adjusting block 31 can be driven to move upward or downward, so as to facilitate the adjustment of the position of the first stirring plate 121.

[0047] Reference Figures 3 to 7 The control assembly 4 includes a first control gear 41 rotatably connected to the first adjusting block 31, a first control rack 42 fixed on the first stirring plate 121, a second control gear 43 rotatably connected to the second adjusting block 32, and a second control rack 44 fixed on the second stirring plate 122.

The first control rack 42 and the second control rack 44 are arranged on opposite sides of the first control gear 41. The first stirring plate 121 and the second stirring plate 122 can be moved in opposite directions by rotating the first control gear 41 and the second control gear 43.

[0048] Reference Figures 3 to 7 A connecting assembly 5 is provided on the stirring shaft 11, and the connecting assembly 5 is used to connect the first control gear 41 and the second control gear 43, and the connecting assembly 5 can drive the first control gear 41 and the second control gear 43 to rotate simultaneously. The connecting assembly 5 includes a fixed rod 51 rotatably connected to the second adjusting block 32 and a first connecting rod 52 and a second connecting rod 53 rotatably connected to the stirring shaft 11. The first adjusting block 31 and the first control gear 41 are both slidably connected to the fixed rod 51. The cross-sections of the fixed rod 51, the first connecting rod 52 and the second connecting rod 53 are the same and are all set to be hexagonal. Plug-in blocks 8 are fixedly installed at both ends of the fixed rod 51. At the same time, a plug-in groove 81 is opened at one end of the first connecting rod 52 close to the fixed rod 51, and a plug-in groove 81 is also opened at one end of the second connecting rod 53 close to the fixed rod 51. When the first adjusting block 31 and the second adjusting block 32 are both rotated to a horizontal state, the plug-in block 8 is plugged into the plug-in groove 81, and then the fixed rod 51 and the second connecting rod 53 can be driven to rotate by rotating the first connecting rod 52, thereby driving the first control gear 41 and the second control gear 43 to rotate.

[0049] Reference Figures 3 to 7 , multiple mounting shafts are rotatably connected to the stirring shaft 11, the top first connecting rod 52 is fixedly connected to the mounting shaft, and the top mounting shaft extends out of the extraction barrel 02, and the adjacent first connecting rods 52 and second connecting rods 53 below are fixedly connected by the mounting shaft, so that by rotating the mounting shaft extending out of the extraction barrel 02 at the top, all the first control gears 41 and second control gears 43 can be driven to rotate, which is more convenient when used. In addition, since three stirring members 12 are provided, three adjusting screws 34 are also provided, and the pitches of the three adjusting screws 34 decrease from top to bottom, so that the pitch of the top adjusting screw 34 is the largest, and then when the top first stirring plate 121 pushes the material to move upward, the bottom first stirring plate 121 also pushes the material upward to move, and the moving speed gradually slows down.

[0050] Since the first control gear 41 and the first adjustment block 31 are both slidably connected to the fixed rod 51 and the first connecting rod 52, after the adjustment assembly 3 drives the first adjustment block 31 to move, the first control gear 41 is on the first connecting rod 52, and then the first control gear 41 can still be driven to rotate through the first connecting rod 52, thereby making it more convenient to adjust the positions of the first stirring plate 121 and the second stirring plate 122.

[0051] Reference Figures 3 to 7 , a first baffle 82 is provided on one side of the first stirring plate 121 close to the stirring shaft 11, and a second baffle 83 is provided on one end of the second stirring plate 122 close to the inner wall of the extraction barrel 02, and then when the first stirring plate 121 drives the material to move to the edge, the material can be pushed better, and at the same time, under the action of the second baffle 83, the material at the edge is better pushed to move to the middle. When the first stirring plate 121 drives the material to move to the edge, and the second stirring plate 122 drives the material to move to the middle position, the moving rod 64 is slid in the reverse direction, and then under the action of the torsion spring 63, the rotating shaft 61 drives the first stirring plate 121 and the second stirring plate 122 to rotate to a vertical state, at this time, the materials on the first stirring plate 121 and the second stirring plate 122 fall into the extraction barrel 02 under the action of gravity, and the purpose of exchanging the position of the materials is achieved. Since the driving component 2 can drive the stirring shaft 11 to rotate, the materials at different positions in the extraction barrel 02 can be exchanged, thereby accelerating the heating of the materials and improving the efficiency of extraction.

[0052] Reference Figures 3 to 8 The driving assembly 2 includes a mounting frame 21 fixed on the reactor body, a first driving motor 22 arranged on the mounting frame 21, a driving gear 23 fixed on the first driving motor 22, and a driven gear 24 fixed on the stirring shaft 11. The driving gear 23 and the driven gear 24 are meshed, and the first driving motor 22 drives the driving gear 23 to rotate, and the driving gear 23 drives the driven gear 24 to rotate, and the driven gear 24 drives the stirring rod and the stirring member 12 to rotate, and the stirring member 12 is used to stir the materials in the extraction barrel 02. A mounting plate 25 is provided on the stirring shaft 11, and a second driving motor 26 is fixedly installed on the mounting plate 25. The output shaft of the second driving motor 26 is fixed to the uppermost mounting shaft, thereby driving the first control gear 41 to rotate.

[0053] A third driving motor 27 is rotatably connected to the mounting frame 21, and the third driving motor 27 is used to be fixedly connected to the adjusting screw 34. The adjusting screw 34 is driven to rotate by the third driving motor 27, and then the position of the moving block 33 is adjusted; a driving cylinder 28 is arranged on the mounting plate 25, and the driving cylinder 28 is fixedly connected to the moving rod 64, and then the moving rod 64 is driven to slide on the stirring shaft 11 by the driving cylinder 28, thereby driving the driving shaft 65 to move, and the driving shaft 65 drives the rotating rod 62 to rotate.

[0054] The implementation principle of a plant liquid extraction device in an embodiment of the present application is: after the material and water are added into the extraction barrel 02, the upper cover 03 is covered, the extraction barrel 02 is heated, the stirring shaft 11 is driven to rotate by the driving component 2, and then the vertically arranged first stirring plate 121 and the second stirring plate 122 are used to stir the material. When it is necessary to exchange the position of the materials, the sliding moving rod 64 drives the moving rod 64 to move the driving shaft 65, and the driving shaft 65 drives the rotating rod 62 and the rotating shaft 61 to rotate, so that the first adjusting block 31, the second adjusting block 32, the first stirring plate 121 and the second stirring plate 122 are rotated to a horizontal state. At this time, the first connecting rod 71 is in the first linkage groove 73, the second connecting rod 72 is in the second linkage groove 74, and the plug-in block 8 is also in the plug-in groove 81. Then the adjusting screw 34 drives the moving block 33 and the first adjusting block 31 to move, so that the first stirring plate 121 moves upward, and drives the material to move above the liquid surface, so that the material on the first stirring plate 121 and the material on the second stirring plate 122 are staggered, and then under the action of the control component 4, the first stirring plate 121 and the second stirring plate 122 move in opposite directions.

[0055] When the first stirring plate 121 drives the material to move to the edge and the second stirring plate 122 drives the material to move to the middle position, the moving rod 64 is slid in the opposite direction, and then under the action of the torsion spring 63, the rotating shaft 61 drives the first stirring plate 121 and the second stirring plate 122 to rotate to a vertical state. At this time, the materials on the first stirring plate 121 and the second stirring plate 122 fall into the extraction barrel 02 under the action of gravity, thereby achieving the purpose of exchanging the positions of the materials. Since the driving component 2 can drive the stirring shaft 11 to rotate, the materials at different positions in the extraction barrel 02 can be exchanged, thereby accelerating the heating of the materials and improving the extraction efficiency.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
