Description

Technical Field

[0001] The utility model relates to the technical field of plant extraction devices, in particular to an oil-liquid separation device for theaflavin extraction. Background Art

[0002] Theaflavins are a chemical substance extracted from black tea. They were first discovered by Roberts. They refer to the orange-yellow substance in black tea that is soluble in ethyl acetate. They are formed by the oxidation and condensation of polyphenols and their derivatives. The content of theaflavins in black tea is generally 0.3% to 1.5%, which plays a decisive role in the color, aroma and quality of black tea. Theaflavins are mainly composed of polyphenols and catechins. They also contain amino acids, vitamin C, vitamin E, provitamin A, flavonoids and flavonols. Theaflavins are the main components of tea pigments and have a total of 12 components. Among them, theaflavins, theaflavins-3-gallate, theaflavins-3,3'-digallate and theaflavins-3'-gallate are the four most important theaflavins. The extraction process of theaflavins requires the use of a chromatograph to separate and purify them. The chromatograph requires the use of a microporous filter membrane for filtration during the oil-liquid separation process.

[0003] Before using the microporous filter membrane, the chromatograph needs to soak the microporous filter membrane for a long time and keep it in a moist state. Most existing chromatographs can only use and replace a single microporous filter membrane during use. The microporous filter membrane needs to be cleaned separately and soaked for a long time before being reused. The microporous filter membrane cannot be quickly switched for use, and the working efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide an oil-liquid separation device for theaflavin extraction to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an oil-liquid separation device for theaflavin extraction, comprising a body, a fixed plate fixedly mounted on the inner wall of the body, a base fixedly connected to the top of the fixed plate, a rotating shaft mounted on the top of the base, a rotating frame rotatably connected to the top of the rotating shaft, a placement box fixedly connected to the grooves around the rotating frame, a sponge pad provided in the placement box, a plurality of liquid leakage grooves provided at the bottom of the placement box, a first bevel gear rotatably connected to the front side of the inner wall of the body, a rotating handle mounted on one side of the first bevel gear, and the rotating handle provided on the outside of the body.

[0006] Furthermore, a second bevel gear meshing with the first bevel gear is installed on one side of the first bevel gear, and the second bevel gear is fixed to the top of the fixed plate through a shaft. The top of the second bevel gear is rotatably connected to a rotating plate, and one end of the top of the rotating plate is fixedly connected to a slider. A sliding groove is provided at the bottom end of the rotating frame, and the slider slides along the travel of the sliding groove to drive the rotating frame to rotate.

[0007] Furthermore, a water receiving trough is installed on the top of the fixed plate. The interior of the water receiving trough is annular and corresponds to the position of the leakage trough at the upper end. A water outlet is provided on one side of the water receiving trough, and a sealing plug is provided on the water outlet for closing the water outlet.

[0008] Furthermore, a fixing block is fixedly connected to the front end of the top of the body, and a sealing plate is fixedly connected to the top of the fixing block. The sealing plate has the same size as the bottom of the placement box, and the sealing plate can close the leakage groove when overlapping with the placement box.

[0009] Furthermore, a water tank is provided on the top of the machine body, an opening for adding liquid is provided on the top of the water tank, and an openable cover is provided at the opening.

[0010] Furthermore, a faucet is fixedly connected to the front of the water tank, and the liquid outlet position at the bottom of the faucet corresponds to the position of the sealing plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the oil-liquid separation device for theaflavin extraction is reasonable and has the following advantages:

[0012] (1) The utility model is provided with a rotating frame. The microporous filter membrane used in the process of separating theaflavin oil usually needs to be soaked for a long time before use, and needs to be kept moist during the placement process. A water tank is used to add soaking liquid in the placement box outside the machine body. The utility model places the microporous filter membranes in four placement boxes on the rotating frame respectively. When the internal microporous filter membrane needs to be switched, it is only necessary to rotate the handle to drive the rotating frame to rotate through the bevel gear set to switch the microporous filter membrane used inside to the outside of the machine body. The speed of replacing the microporous filter membrane is accelerated during use, and the efficiency of the machine body is improved;

[0013] (2) The utility model can keep the filter membrane moist for a long time by placing the sponge pad in the box. When the placement box is rotated to the inside, the soaking liquid will leak out through the leakage groove due to the separation of the sealing plate at the bottom, but the sponge pad will still remain moist, which can ensure the normal use of the filter membrane. By setting up four placement boxes, they can be switched for use respectively. The utility model can automatically filter the soaking liquid when switching the microporous filter membrane for use, while ensuring the good moistness of the filter membrane in use inside the body.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-7 , a technical solution provided by the utility model:

[0024] Example 1:

[0025] In this embodiment, an oil-liquid separation device for theaflavin extraction includes a body 1, a fixed plate 14 is fixedly installed on the inner wall of the body 1, the top of the fixed plate 14 is fixedly connected to a base 5, a rotating shaft 6 is installed on the top of the base 5, the top of the rotating shaft 6 is rotatably connected to a rotating frame 2, and a placement box 4 is fixedly connected to the grooves around the rotating frame 2. A sponge pad 20 is provided in the placement box 4, and the sponge pad 20 can keep the microporous filter membrane in a moist state. A plurality of leakage grooves 11 are provided at the bottom of the placement box 4, and a first bevel gear 7 is rotatably connected to the front side of the inner wall of the body 1. A rotating handle 10 is installed on one side of the first bevel gear 7, and the rotating handle 10 is provided on the outside of the body 1.

[0026] In this embodiment, a second bevel gear 9 meshing with the first bevel gear 7 is installed on one side of the first bevel gear 7. The second bevel gear 9 is fixed to the top of the fixed plate 14 through a shaft. The top of the second bevel gear 9 is rotatably connected to the rotating plate 13. One end of the top of the rotating plate 13 is fixedly connected to the slider 12. A slide groove 8 is provided at the bottom end of the rotating frame 2. The slider 12 slides along the stroke of the slide groove 8 to drive the rotating frame 2 to rotate.

[0027] When extracting theaflavins, a chromatograph is used to separate oil and liquid. During the oil separation process, a microporous filter membrane is required for filtration. First, four pre-soaked microporous filter membranes can be placed in four placement boxes 4 respectively, and then the body 1 can be started to perform the oil separation operation. After use, the microporous filter membrane can usually be reused, but it needs to be cleaned and soaked. The user can turn the rotating handle 10. After the rotating handle 10 is rotated by force, it drives the rotating plate 13 to rotate through the bevel gear set. The rotation of the rotating plate 13 drives the slider 12 to move along the slide 8, which can drive the rotating frame 2 as a whole to rotate with the rotating axis 6 as the center of the circle. When the slider 12 disengages from the first slide 8, it will enter the next slide 8 and so on to rotate the rotating frame 2. When the used microporous filter membrane placement box 4 is rotated to the sealing plate 19 outside the body 1, the user can rotate and open the faucet 18 to replenish the soaking liquid in the placement box 4. At this time, the new microporous filter membrane inside the body 1 can be used to continue the oil separation operation.

[0028] Example 2:

[0029] In this embodiment, a water receiving trough 15 is installed on the top of the fixed plate 14. The interior of the water receiving trough 15 is annular. The position of the water receiving trough 15 corresponds to the position of the upper leakage trough 11. A water outlet 16 is provided on one side of the water receiving trough 15, and a sealing plug is provided on the water outlet 16 for closing the water outlet 16.

[0030] In this embodiment, a fixed block 21 is fixedly connected to the front end of the top of the body 1, and a sealing plate 19 is fixedly connected to the top of the fixed block 21. The sealing plate 19 has the same size as the bottom of the placement box 4. When the sealing plate 19 overlaps with the placement box 4, the leakage groove 11 can be closed. When the placement box 4 rotates away from the sealing plate 19, the soaking liquid will pass through the leakage groove 11 into the corresponding water receiving groove 15 below, and the soaking liquid will be automatically discharged.

[0031] In this embodiment, a water tank 3 is provided on the top of the body 1. The top of the water tank 3 is provided with an opening for adding liquid. An openable cover 17 is provided at the opening. When the soaking liquid in the water tank 3 is used up, the user can open the cover 17 to refill it.

[0032] In this embodiment, a faucet 18 is fixedly connected to the front of the water tank 3, and the liquid outlet position at the bottom of the faucet 18 corresponds to the position of the sealing plate 19. The user can rotate and open the faucet 18 to replenish the soaking liquid in the corresponding placement box 4 on the sealing plate 19.

[0033] When the outer microporous filter membrane is soaked and ready for use, the user can rotate the rotary handle 10 to soak and place another microporous filter membrane. When the placement box 4 rotates away from the sealing plate 19, the soaking liquid will enter the corresponding water receiving tank 15 below through the leakage tank 11 and automatically discharge the soaking liquid. The liquid in the water receiving tank 15 can be discharged through the water outlet 16.

[0034] Working principle: When extracting theaflavins, a chromatograph is used to separate the oil and liquid. During the oil separation process, a microporous filter membrane is required for filtration. First, four pre-soaked microporous filter membranes can be placed in four placement boxes 4 respectively. The sponge pad 20 in the placement box 4 can keep the microporous filter membrane moist. Then the body 1 can be started to perform the oil separation operation. After use, the microporous filter membrane can usually be reused, but it needs to be cleaned and soaked. The user can turn the rotating handle 10. After the rotating handle 10 is rotated under force, it drives the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the rotating plate 13 to rotate. During the rotation of the rotating plate 13, the slider 12 is stuck in the slide groove 8 and can only move along the stroke of the slide groove 8. The slider 1 2 moves along the chute 8 to drive the rotating frame 2 as a whole to rotate around the rotating shaft 6 as the center of the circle. When the slider 12 leaves the first chute 8, it will enter the next chute 8 and so on to rotate the rotating frame 2. When the used microporous filter membrane placement box 4 is rotated to the sealing plate 19 outside the body 1, the user can rotate and open the faucet 18 to replenish the soaking liquid in the placement box 4. At this time, the new microporous filter membrane in the body 1 can be used to continue the oil-liquid separation operation. When the external microporous filter membrane is soaked and ready for use, the user can rotate the rotating handle 10 to soak and place another microporous filter membrane. When the placement box 4 rotates away from the sealing plate 19, the soaking liquid will enter the corresponding water receiving tank 15 below through the leakage tank 11 and automatically drain the soaking liquid. The liquid in the water receiving tank 15 can be discharged through the water outlet 16.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
