Description

Technical Field

[0001] This utility model relates to the field of tea polyphenol purification technology, specifically to a device for the extraction and purification of tea polyphenols by chromatography. Background Technology

[0002] Tea polyphenols are a general term for phenolic substances and their derivatives in tea. Phenolic compounds that undergo complexation reactions with ferrous ions in the water extract of tea are called tea polyphenols.

[0003] A search revealed a utility model with publication number CN215917384U, which discloses a chromatographic purification device for tea polyphenols. The device includes a purification tank, a heating mechanism, and a stirrer. The heating mechanism is connected to the surface of the purification tank, and the stirrer is detachably connected to the top of the tank. The heating mechanism consists of a controller, a conductive rod, and a heating plate. The conductive rod is connected to one side of the controller, and the heating plate is connected to the end of the conductive rod, located inside the purification tank. This device accelerates the reaction between the raw material and the chemical reagents during purification, allowing for rapid precipitation of tea polyphenols and improving purification efficiency. It also filters the raw material, increasing its purity and facilitating purification.

[0004] However, the above-mentioned existing technology still has the following shortcomings when in use: the purification tank is an integrated structure, which is equipped with a heating mechanism and a stirrer. After a period of use, dirt (such as adhering substances) will form on the inner wall of the purification tank. Since this dirt adheres to the inner wall of the purification tank, the outer wall of the stirrer and the heating mechanism, it is inconvenient and incomplete to clean. This defect will directly affect the purity of the tea polyphenols after purification.

[0005] Therefore, this utility model provides a device for the extraction and purification of tea polyphenols by chromatography. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a chromatographic purification device for tea polyphenol extraction, so as to solve the problems mentioned in the background technology. This utility model has the advantages of making it easier to clean the inner wall of the purification cylinder, and also has the advantages of making the rinsing and cleaning process more environmentally friendly.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a chromatographic purification device for tea polyphenol extraction, comprising a base and a purification cylinder, wherein a discharge valve pipe is provided at the bottom of the purification cylinder, a vertical plate is provided at the top of the base, a slide block is slidably connected to one side of the vertical plate, the purification cylinder and the slide block are rotatably connected to its top opening, a crossbeam is fixedly connected to the top of the vertical plate, and a sealing cylinder opposite to the top of the purification cylinder is rotatably connected below the crossbeam, wherein a heating tube is provided inside the sealing cylinder.

[0008] Furthermore, one end of the slide is fixedly connected to a guide sleeve fitted on the vertical plate, and the other end of the slide is fixedly connected to a positioning ring, in which a rotating sleeve is fitted, and the purification cylinder is fixedly fitted inside the rotating sleeve.

[0009] Furthermore, the top of the base is connected to one side of the guide sleeve via a lifting rod, and a control motor is fixedly connected to one side of the positioning ring. The output shaft of the control motor is fixedly connected to a transmission gear, and a driven gear that meshes with the transmission gear is fixedly sleeved on the outside of the rotating sleeve.

[0010] Furthermore, a positioning shaft is fixedly connected to the bottom of the crossbeam, and a sleeve communicating with the inner cavity is fixedly provided on the top of the sealing cylinder. The sleeve is fitted onto the positioning shaft and the two are rotatably connected.

[0011] Furthermore, a positioning channel is provided inside the positioning shaft, and a positioning tube that passes through the positioning channel is fixedly connected to the top of the heating tube.

[0012] Furthermore, a first feed pipe and a second feed pipe are fixedly connected to the positioning shaft, and one end of both the first feed pipe and the second feed pipe extends into the sealing cylinder.

[0013] Furthermore, a horn tube with its large end facing upwards is fixedly connected to the top of the purification tube, and the outer diameter of the bottom of the sealing tube is located between the diameters of the large and small ends of the horn tube. A sealing ring is fitted around the bottom of the sealing tube.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a vertical plate, a sliding block, and a sealing cylinder are provided. After the sliding block drives the purification cylinder to move upward, it will form a closed purification tank with the sealing cylinder. After the purification cylinder moves downward, it will separate from the sealing cylinder. At this time, the opposite ends of the sealing cylinder and the purification cylinder are in an open state. This arrangement makes it convenient for operators to perform a comprehensive cleaning operation on the inner wall of the purification cylinder and the inner wall of the sealing cylinder, and to thoroughly clean the dirt inside the purification cylinder and the sealing cylinder.

[0016] 2. In this utility model, both the purification cylinder and the sealing cylinder are rotating. When they are connected and rotated, they can stir the internal mixture without the need for a matching stirrer, which reduces the difficulty of cleaning dirt.

[0017] 3. In this utility model, a trumpet tube is set at the top of the purification cylinder, and the outer diameter of the lower opening of the sealing cylinder is smaller than the outer diameter of the large end of the trumpet tube. When cleaning the inner wall of the sealing cylinder and the heating tube, dirt and sewage will fall directly into the purification cylinder and then be discharged through the discharge valve at the bottom of the purification cylinder. This has the advantage of being more environmentally friendly in cleaning dirt. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 3This utility model provides a technical solution: a chromatographic purification device for tea polyphenol extraction, comprising a base 1 and a purification cylinder 2. A discharge valve pipe 21 is provided at the bottom of the purification cylinder 2. A vertical plate 3 is provided at the top of the base 1. A slide block 4 is slidably connected to one side of the vertical plate 3. Preferably, one end of the slide block 4 is fixedly connected to a guide sleeve 41 fitted onto the vertical plate 3. The purification cylinder 2 and the slide block 4 are rotatably connected to their top openings. Preferably, the other end of the slide block 4 is fixedly connected to a positioning ring 42, and a rotating sleeve 43 is fitted inside the positioning ring 42, with the purification cylinder 2 fixedly fitted inside the rotating sleeve 43. A crossbeam 5 is fixedly connected to the top of the vertical plate 3. A sealing cylinder 6, opposite to the top of the purification cylinder 2, is rotatably connected below the crossbeam 5. Preferably, a positioning shaft 51 is fixedly connected to the bottom of the crossbeam 5, and a sleeve 61 communicating with the inner cavity is fixedly provided at the top of the sealing cylinder 6. The sleeve 61 is fitted onto the positioning shaft 51, and the two are rotatably connected. A heating tube 7 is installed inside the sealing cylinder 6. Preferably, a positioning channel 511 is opened inside the positioning shaft 51, and a positioning tube 71 that passes through the positioning channel 511 is fixedly connected to the top of the heating tube 7. A wire connected to the heating tube 7 is installed inside the positioning tube 71. The sealing cylinder 6 serves to seal the top opening of the purification cylinder 2. In use, the control slide 4 rises, and when the bottoms of the purification cylinder 2 and the sealing cylinder 6 abut against each other, they form a closed cavity for chromatography purification. When the purification cylinder 2 and the sealing cylinder 6 separate, the opposite ends of the purification cylinder 2 and the sealing cylinder 6 are in a large open state, which provides space for the operator to clean the inner walls of the purification cylinder 2 and the sealing cylinder 6, as well as the heating tube 7.

[0024] Among them, the heating tube 7 can increase the speed of the chromatography treatment of tea polyphenol stock solution and reagent mixture when heated. When the purification tube 2 and the sealing tube 6 are combined and rotated, they can stir the mixture inside, so that the mixture can be fully dissolved. In order to improve the stirring effect, baffles evenly distributed in the circumference can be set on the inner wall of the purification tube 2.

[0025] In this embodiment, the top of the base 1 is connected to one side of the guide sleeve 41 via a lifting rod 8. The lifting rod 8 can be one of a cylinder, a hydraulic cylinder, or an electric push rod. A control motor 9 is fixedly connected to one side of the positioning ring 42. A transmission gear 91 is fixedly connected to the output shaft of the control motor 9. A driven gear 431 that meshes with the transmission gear 91 is fixedly sleeved on the outside of the rotating sleeve 43. After the control motor 9 is started, it will drive the purification cylinder 2 to rotate through the meshing of the transmission gear 91 and the driven gear 431.

[0026] In this embodiment, a first feed pipe 512 and a second feed pipe 513 are fixedly connected to the positioning shaft 51. One end of the first feed pipe 512 and the second feed pipe 513 both extend into the sealing cylinder 6. The function of the first feed pipe 512 is to introduce the tea polyphenol stock solution that needs to be chromatographically processed into the purification cylinder 2. The function of the second feed pipe 513 is to introduce the reagent into the purification cylinder 2.

[0027] In this embodiment, a horn-shaped tube 22 with its large end facing upward is fixedly connected to the top of the purification tube 2. The outer diameter of the bottom of the sealing tube 6 is between the diameters of the large and small ends of the horn-shaped tube 22. Thus, when the purification tube 2 and the sealing tube 6 come into contact, the bottom of the sealing tube 6 will abut against the inner conical wall of the horn-shaped tube 22. This arrangement allows the dirt generated when the operator cleans the inside of the sealing tube 6 to fall directly into the purification tube 2 under the guidance of the inner conical wall of the horn-shaped tube 22, avoiding cleaning contamination. A sealing ring 101 is fitted at the bottom of the sealing tube 6, which seals the joint between the purification tube 2 and the sealing tube 6.

[0028] Working principle: After a period of use, when the internal parts of the purification cylinder 2 and the sealing cylinder 6 need to be cleaned, firstly, control the lifting rod 8 to drive the slide 4 to descend, separating the purification cylinder 2 and the sealing cylinder 6. The operator can then clean and rinse the inner wall of the purification cylinder 2 through the opening. Then, clean and rinse the inner wall of the sealing cylinder 6. The dirt generated during cleaning and rinsing of the sealing cylinder 6 will fall directly into the purification cylinder 2. When the discharge valve pipe 21 is opened, the dirt inside can be flushed out. After the cleaning is completed, control the slide 4 to drive the purification cylinder 2 back to the state of being against the sealing cylinder 6. At this time, normal chromatography can be performed.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
