Description

Technical Field

[0001] The utility model relates to the technical field of eucommia gum extraction, in particular to an eucommia gum extractor. Background Art

[0002] Eucommia gum exists in eucommia leaves, bark and fruits. Eucommia gum and natural rubber have the same chemical composition but different molecular structures. Eucommia gum is trans-polyisoprene, while natural rubber is cis-polyisoprene. Since the same eucommia gum molecules can exhibit rubber state or different plastic states due to different vulcanization methods, eucommia gum has very important application value and is a new functional material with multiple uses.

[0003] At present, the manufacturing method of eucommia gum by benzene-methanol method is as follows: take dried fruits and crush them → extract in a benzene extractor for 24 - 48 hours → filter → add 1 - 1.5 times the amount of methanol to precipitate for 2h → discard the precipitate liquid, and then naturally dry the precipitate to obtain eucommia gum.

[0004] Therefore, an eucommia gum extractor is needed to extract eucommia gum.

[0005] For example, the prior art Chinese patent publication number "CN212700650U" provides an eucommia gum extractor, which includes an extraction tank. The upper surface of the extraction tank is threadedly connected with a first connection cover. The upper end of the first connection cover is fixedly installed with a crushing tank. A crushing motor is installed on the front outer wall of the crushing tank. The top position of the vertical outer wall on one side of the extraction tank is fixedly installed with a benzene adding pipe. The lower end of the extraction tank is fixedly installed with a filtering pipe. A switch valve is installed on the filtering pipe. The lower end of the filtering pipe is fixedly connected with a second connection cover. The lower surface of the second connection cover is threadedly connected with a precipitation tank.

[0006] This device realizes the integration of the crushing, extraction, filtration and precipitation processes required for eucommia gum production, avoids the trouble of using multiple devices for separate treatment and multiple addition and removal operations, greatly improves work efficiency, and can observe the working conditions in the extraction tank and precipitation tank in real time, making it more convenient for people to control the extraction and precipitation effects.

[0007] In the existing eucommia gum extractor, during the process of extracting eucommia gum raw materials placed in the extraction tank with methanol liquid, it is relatively quiet and fails to mix and stir the eucommia gum raw materials to improve the contact between them and the methanol liquid, which is not conducive to the full and rapid extraction of eucommia gum raw materials.

[0039] Example 2

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, An eucommia gum extraction device shown in the figure, including an extraction tank 1. A placing mechanism is arranged inside the extraction tank 1. A top cover mechanism is arranged at the top of the extraction tank 1. A dispersing mechanism is arranged between the top cover mechanism and the placing mechanism. The placing mechanism includes a placing plate 13, a first retaining ring 11 and a second retaining ring 12. A first rotating rod 17 is fixed in the middle of the bottom end of the placing plate 13. A first motor 4 is installed at the bottom end of the first rotating rod 17. Third liquid flow holes 16 are formed on the surface of the placing plate 13. The first retaining ring 11 is fixed at the top edge of the placing plate 13, and first liquid flow holes 14 are formed on its surface. The second retaining ring 12 is fixed at the top of the placing plate 13 and located inside the first retaining ring 11, and second liquid flow holes 15 are formed on its surface. The top cover mechanism includes a box cover 5. A eucommia gum raw material adding pipe 9 and a methanol adding pipe 6 are arranged at the top of the box cover 5. A first limiting groove 25 and a second limiting groove 22 are fixed at the bottom end of the box cover 5. The dispersing mechanism includes a dispersing rod 19, a second rotating rod 21 and dispersing strips 20 fixed on its surface, which are used to stir and disperse the eucommia gum raw material inside the placing mechanism.

[0041] In the placing mechanism, the placing plate 13 is rotatably installed at the bottom end inside the extraction tank 1 through the first rotating rod 17 and a sliding rod 18. The first retaining ring 11 and the second retaining ring 12 are fixed at the top of the placing plate 13. Therefore, after the eucommia gum raw material is extracted inside the extraction tank 1 and the extraction liquid is discharged from the liquid outlet pipe 3, the first motor 4 can drive the first rotating rod 17 and the placing plate 13 to continuously rotate, and the extracted eucommia gum raw material is subjected to rotational centrifugation through the first retaining ring 11, the second retaining ring 12, the first liquid flow holes 14, the second liquid flow holes 15 and the third liquid flow holes 16, so as to throw out the residual extraction liquid in the eucommia gum raw material and reduce the residual extraction liquid.

[0042] A sliding rod 18 is fixed at the bottom end of the placing plate 13. A sliding groove 26 is formed at the bottom end inside the extraction tank 1. The bottom end of the sliding rod 18 is slidably inserted into the inside of the sliding groove 26.

[0043] The placing plate 13 is of a circular plate structure and is horizontally arranged.

[0044] Working mode; a placing mechanism is arranged inside the extraction tank 1, and a top cover mechanism is arranged at the top of the extraction tank 1. A dispersion mechanism is arranged inside the placing mechanism through the top cover mechanism. Therefore, the placing plate 13 drives the first retaining ring 11 and the second retaining ring 12 to be installed inside the extraction tank 1, and drives rotation through the sliding rod 18 and the first rotating rod 17. The tank cover 5 tightly covers the extraction tank 1, the second rotating rod 21 drives the dispersion bar 20 to insert into the inside of the second retaining ring 12, and the dispersion rod 19 inserts between the first retaining ring 11 and the second retaining ring 12.

[0045] Therefore, methanol solution for extracting eucommia gum raw materials is added into the extraction tank 1 through the methanol adding pipe 6, and eucommia gum raw materials are placed into the second retaining ring 12 at the top of the placing plate 13 from the eucommia gum raw material adding pipe 9. After that, the first motor 4 drives the first rotating rod 17, the sliding rod 18 and the placing plate 13 to rotate around the chute 26, so as to drive the eucommia gum raw materials to rotate, increase the mixing contact with the methanol liquid. At the same time, the second motor 8 drives the second rotating rod 21 and the dispersion bar 20 to rotate, which can stir and disperse the eucommia gum raw materials and can cut up the eucommia gum raw materials with larger volume.

[0046] Therefore, during the rotation process of the eucommia gum raw materials, they can be stirred and dispersed through the dispersion bar 20 and the dispersion rod 19. Moreover, the eucommia gum raw materials with smaller volume enter the inside of the first retaining ring 11 from the second retaining ring 12 through the second liquid flow hole 15, separate the eucommia gum raw materials with different sizes, and disperse and cut up the eucommia gum raw materials with larger volume. In this way, the extraction contact between the eucommia gum raw materials and the extraction liquid is increased, and the extraction effect of the eucommia gum raw materials is improved.

Therefore, after the eucommia gum raw materials are extracted inside the extraction tank 1 and the extraction liquid is discharged through the liquid outlet pipe 3, the first motor 4 can drive the first rotating rod 17 and the placing plate 13 to continuously rotate, and perform rotational centrifugal treatment on the extracted eucommia gum raw materials through the first retaining ring 11, the second retaining ring 12, the first liquid flow hole 14, the second liquid flow hole 15 and the third liquid flow hole 16, so as to throw out the residual extraction liquid in the eucommia gum raw materials and reduce the residue of the extraction liquid.
