Description

Technical Field

[0001] This invention relates to the field of tea pigment processing technology, and in particular to a separation and purification device for tea pigment processing. Background Technology

[0002] Tea pigments are a class of water-soluble phenolic pigments extracted from tea leaves. They possess various biological activities, including antioxidant, lipid-lowering, and anti-tumor effects, and are widely used in the food, pharmaceutical, and health product industries. Separation and purification are crucial steps in the processing of tea pigments, and the structural rationality of the separation and purification equipment directly affects extraction efficiency and purity. Current equipment still has the following shortcomings in use: Traditional tea pigment processing equipment uses dispersed filtration and adsorption components for separation and purification, requiring additional pipelines, which can easily lead to extract loss or contamination. Furthermore, the components are complex to connect, making maintenance difficult. The storage containers for tea pigments are often secured by multiple sets of bolts, and the seals of the storage containers are also secured by multiple sets of bolts. Disassembly and assembly require the use of tools to loosen and loosen the bolts one by one. Furthermore, if the bolts are rusty or have impurities adhering to them, it will affect the disassembly efficiency, making the operation cumbersome and time-consuming. The crushing device of separation and purification equipment is usually a single stirring or crushing device, which often leads to insufficient mixing between the crushed tea leaves and the extract, resulting in low dissolution efficiency. In addition, the filtration structure of tea leaves is simple, making it difficult to effectively remove impurities, macromolecules and ineffective components from the extract, thus affecting the purity of tea pigments. Therefore, how to provide a separation and purification device for tea pigment processing is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] One objective of this invention is to provide a separation and purification device for tea pigment processing. The tank structure of this invention integrates multi-stage filtration and adsorption components, eliminating the need for additional piping, reducing extract loss and contamination, and facilitating easy component connection and maintenance. The storage component utilizes a stabilizing pin for positioning and a locking ring with inclined surface compression to achieve rapid disassembly and sealing of the storage tank, which is more efficient than traditional bolt methods. The sealing structure uses a stepped plug to seal the feed pipe, combined with a positioning rod and spring, ensuring both reliable sealing and flexible operation, allowing for tool-free unlocking. The crushing device uses a single motor to drive multiple components in tandem, achieving coordinated tea crushing, extract agitation, and vibration, improving dissolution efficiency and saving energy. Example 2 includes a delivery pump for enhanced adaptability, ensuring the delivery of high-viscosity extracts. Example 3 adds valves for easy impurity discharge and cleaning, comprehensively improving the equipment's practicality and purification efficiency.

[0016] Furthermore, the bottom of the preliminary filter screen is provided with a retaining ring at the outer perimeter, and a second docking sleeve is provided on one side of the preliminary filter screen. The second docking sleeve has an arc surface on one side. A first docking sleeve is provided on the inner side of the separation tank. The support frame, separation tank, tea placing tube, extract delivery tube, sealing cover, stabilizing plate, first drain pipe, first docking sleeve, and second drain pipe cooperate with each other to form the tank structure. An arc groove is opened on one side of the first docking sleeve, and the arc surface of the second docking sleeve extends into the interior of the arc groove. The first docking sleeve and the second docking sleeve are connected.

[0017] The beneficial effects of this invention are: In this invention, the tank structure integrates a preliminary filter, a flow-guiding shell, a tertiary filter, and an adsorption column, forming a continuous process of preliminary filtration, secondary filtration, final filtration, and adsorption purification. The preliminary filter first filters out coarse tea residue. The filtered extract enters the flow-guiding shell through the filter hole in the middle of the separation tank, and then is transported to the tertiary filter for fine filtration through a ring-shaped array of flow-guiding pipes. Finally, it enters the adsorption column to complete the adsorption of tea pigments. All filtration and purification components are organically connected through the tank structure, eliminating the need for additional transport pipelines, reducing losses and contamination during the transport of the extract, and improving the efficiency and purity of tea pigment purification. Specifically, the second docking sleeve of the preliminary filter screen mates with the arc groove of the first docking sleeve inside the separator tank via its arc surface, achieving circumferential positioning and quick installation of the preliminary filter screen without the need for complex alignment operations. At the same time, the first docking sleeve and the second docking sleeve are connected, facilitating the discharge of filter screen impurities through the drain pipe and preventing impurity accumulation and blockage. In addition, the diversion housing is fixed to the outside of the separator tank with locking bolts, and anti-loosening plates prevent the bolts from loosening. This ensures that the diversion housing is installed securely, prevents leakage of the extractant, and allows for quick disassembly when cleaning the diversion housing, reducing maintenance difficulty.

[0018] The storage assembly consists of a storage tank and a sealing plate to store the extract. The mounting hole at the bottom of the storage tank engages with the stabilizing pin of the sealing plate, enabling quick positioning of the storage tank and the sealing plate without repeated adjustments to complete the initial docking. A locking ring is included, which can quickly lock the storage tank and the sealing plate by rotating it. Compared with the traditional bolt locking method, there is no need to tighten or remove multiple sets of bolts one by one. The locking ring can be tightened by rotating it in the forward direction and unlocked by rotating it in the reverse direction, enabling quick assembly and disassembly of the storage tank and significantly reducing the time required for cleaning or replacing the storage tank.

[0019] A sealing plug is installed to seal the storage tank; a second positioning rod is installed to automatically position and support the sealing plug after it is opened, preventing the sealing plug from being lost or contaminated due to random placement; a locking plate is installed to quickly and securely stabilize the sealing plug. In addition, the sealing plug can be quickly unlocked by pulling the connecting plate upwards, without the need for tools. The operation is convenient and it balances sealing performance with ease of use. Compared with the traditional bolt locking method, it eliminates the need to tighten or remove multiple sets of bolts one by one.

[0020] A crushing device is installed to crush the tea leaves and fully mix them with the extract. Specifically, the crushing device is driven by an electric motor, and the crushing teeth are set on the outside of the rotating tube, the first rotating shaft, and the second rotating shaft. The rotating tube, the first rotating shaft, and the second rotating shaft rotate synchronously with the gears. There is no need to set up multiple additional power sources, which simplifies the device structure, reduces energy consumption, and allows a set of crushing teeth to crush the tea leaves together, increasing the contact area between the tea leaves and the extract and improving the dissolution efficiency of tea pigments. Meanwhile, a spiral blade is installed on the second rotating shaft. The spiral blade stirs the extract, creating upward and downward convection, which further promotes the full mixing of tea leaves and extract, avoiding the problem of insufficient extraction in some areas.

[0021] In addition, the friction block at the bottom of the rotating disk comes into contact with the extrusion roller to generate friction and vertical extrusion force, which causes the first rotating shaft to drive the crushing teeth to move up and down and vibrate slightly, assisting in the crushing of tea leaves and mixing with the extract, further improving the extraction efficiency and achieving a multi-dimensional synergistic effect of crushing, stirring and vibration.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] Example 1: Please refer to Figures 1 to 12: This invention proposes a separation and purification device for tea pigment processing, comprising: a tank structure 1, the tank structure 1 including a support frame 101, a separation tank 102 fixedly installed above the support frame 101, a sealing cap 105 installed at the upper end of the separation tank 102, a tea placing tube 103 provided on one side of the upper end of the separation tank 102, an extraction liquid conveying tube 104 provided on the other side of the separation tank 102, a sealing plate 206 installed on one side of the extraction liquid conveying tube 104, and a storage container installed above the sealing plate 206. Tank 201 has a drain bend at the bottom of the sealing plate 206. The tea placing pipe 103, the extract conveying pipe 104, and the drain bend are each provided with a connecting flange on the side. The connecting flanges of the extract conveying pipe 104 and the drain bend are installed with matching bolts. After the bolts are installed, the extract conveying pipe 104 and the drain bend are stably assembled, ensuring that the tea extract is stably conveyed from the separation tank 102 through the extract conveying pipe 104 and the drain bend to the storage tank 201, while also facilitating the disassembly and maintenance of the pipeline in the future. In this embodiment, a set of stabilizing pins 207 arranged in a circular array are installed around the periphery of the sealing disc 206. A set of mounting holes is opened at the periphery of the bottom of the storage tank 201, aligning the mounting holes with the stabilizing pins 207. The stabilizing pins 207 pass through the interior of the mounting holes. Specifically, the circular array of stabilizing pins 207, in conjunction with the mounting holes, enables precise positioning and rapid docking of the storage tank 201 and the sealing disc 206, while enhancing the stability of their connection. A movable locking ring 203 is installed at the bottom of the storage tank 201, and a set of positioning bolts 205 are installed at the bottom of the storage tank 201. A set of sliding holes, which are oval-shaped, are opened on the inner side of the locking ring 203, through which the positioning bolts 205 pass. A set of extrusion protrusions 204 are provided on the upper side of the locking ring 203, and the side plates of the extrusion protrusions 204 have a set of inclined surfaces. An annular groove is formed at the upper end of 07, and the extrusion protrusion 204 extends into the interior of the annular groove. The storage tank 201, feed pipe 202, locking ring 203, extrusion protrusion 204, positioning bolt 205, sealing disc 206, and stabilizing pin 207 cooperate to form the storage component 2. Specifically, the oval-shaped sliding hole allows the locking ring 203 to rotate along the positioning bolt 205. When the locking ring 203 is rotated, the inclined surface of the extrusion protrusion 204 presses against the annular groove of the stabilizing pin 207, so that the storage tank 201 and the sealing disc 206 fit tightly together, automatically enhancing the connection and sealing performance. At the same time, it enables the storage tank 201 to be quickly locked and unlocked, which is convenient for the storage tank 201 to be disassembled and cleaned. After rotating the locking ring 203 in the opposite direction, the storage tank 201 and the sealing disc 206 can be quickly unlocked, which solves the problem of the storage tank 201 and the sealing disc 206 being difficult to lock and remove with a set of bolts. In this embodiment, the outer side of the storage tank 201 is provided with two transverse support plates 301. A feed pipe 202 is provided on one side of the storage tank 201, communicating with the interior of the storage tank 201. A sealing plug 305 is installed on one side of the feed pipe 202. The sealing plug 305 has a cylindrical stepped structure, with its small diameter extending into the interior of the feed pipe 202. Specifically, the cylindrical stepped sealing plug 305 can tightly fit against the inner wall of the feed pipe 202, achieving effective sealing of the feed pipe 202. A second positioning rod 306 is installed at the bottom of the feed pipe 202. A transverse sliding hole is formed on the outer periphery of the sealing plug 305. The second positioning rod 306 passes through the interior of the sliding hole. A support spring is installed on the outer side of the second positioning rod 306. The support spring pushes the sealing plug 305 into the interior of the feed pipe 202. After the sealing plug 305 is stretched outward, the second positioning rod 306 can position and support the opened sealing plug 305, solving the problem of the sealing plug 305 being placed randomly after opening and the problem of inconvenient positioning of the sealing plug 305 during installation. The support spring provides continuous elastic force to the sealing plug 305. One side of the support plate 301 is open. A vertical sliding hole is provided, and two first positioning rods 302 are inserted into the sliding hole. A connecting plate 303 is installed between the two first positioning rods 302. A locking plate 304 is provided between the two first positioning rods 302. A support spring is installed on the outer side of the first positioning rods 302, between the support plate 301 and the locking plate 304. The inner side of the locking plate 304 is in close contact with the outer side of the sealing plug 305. By pulling the locking plate 304 and the connecting plate 303 upward, the sealing plug 305 can be unlocked. 01. The first positioning rod 302, connecting plate 303, locking plate 304, sealing plug 305, and second positioning rod 306 work together to form the sealing structure 3. Specifically, the support spring pushes the locking plate 304 to press the sealing plug 305, further enhancing the sealing effect of the sealing plug on the feed pipe 202; the connecting plate 303 enables the two first positioning rods 302 to move synchronously, and the sealing plug can be unlocked by pulling it upward, which is convenient to operate. The overall sealing structure 3 takes into account both sealing performance and operational flexibility, ensuring the sealing of the storage tank 201 and solving the problem of traditional sealing plugs 305 being locked with bolts.

Specifically, the drive spur gear 707 drives the driven spur gear 711 and the second rotating shaft 712 to rotate, allowing the crushing tooth 706 on the second rotating shaft 712 to further crush the tea leaves. The spiral blades 713, distributed vertically, agitate the extract in the separation tank 102 when rotating, creating convection between the tea leaves and the extract, ensuring full contact between the tea leaves and the extract, further improving extraction and crushing efficiency.

[0029] The working principle of this embodiment: Align the mounting hole at the bottom of storage tank 201 with the retaining pin 207 of sealing disc 206, and press down to make the retaining pin 207 pass through the mounting hole, thus completing the initial positioning of storage tank 201 and sealing disc 206; rotate the locking ring 203 at the bottom of storage tank 201 so that the inclined surface of the extrusion protrusion 204 presses against the annular groove of retaining pin 207, thus completing the locking between storage tank 201 and sealing disc 206; rotating the locking ring 203 in the opposite direction can unlock storage tank 201 and sealing disc 206, thus solving the problem of troublesome traditional bolt disassembly and assembly; The upward pulling of the connecting plate 303 causes the locking plate 304 to move upward, unlocking the sealing plug 305. The sealing plug 305 is pulled outward, and the tea to be processed is put into the separation tank 102 through the tea placing tube 103. The extraction liquid is added into the storage tank 201. Then, the sealing plug 305 is pushed to reset, and the support spring pushes the locking plate 304 to press the sealing plug 305, thereby sealing the feed tube 202. When the electric motor 701 is started, the rotating tube 703 drives the first rotating shaft 705 and the crushing teeth 706 to rotate and crush the tea leaves. At the same time, the friction block 710 contacts the extrusion roller 709 to generate vibration and up-and-down force. The spiral blade 713 of the second rotating shaft 712 rotates and stirs the extract and forms up-and-down convection. When the drive spur gear 707 rotates, it drives the rotating disk 708 to rotate synchronously. The U-shaped friction block 710 at the bottom of the rotating disk 708 and the extrusion roller 709 generate friction and vertical extrusion force, causing the first rotating shaft 705 to drive the crushing tooth 706 to move up and down and vibrate slightly, which helps the tea leaves and extract to mix fully and improve the dissolution efficiency of tea pigments. The primary filter 8 performs preliminary filtration of the tea leaves. The filtered liquid enters the inlet shell 4 for secondary filtration through the filter hole in the middle of the separator 102. The liquid is then transported to the top of the tertiary filter 9 for final filtration through the inlet pipe 6. The liquid moves to the outer adsorption column 10, where it adsorbs and purifies the tea pigments. Support frame 101 supports the entire tank structure 1, with separation tank 102 serving as the core reaction vessel; electric motor 701 provides power, driving bevel gear 702 and driven bevel gear 704 to rotate rotating tube 703. Rotating tube 703, through positioning protrusions and positioning grooves, drives first rotating shaft 705 and crushing teeth 706 to rotate, driving spur gear 707 and driven spur gear 711 to drive second rotating shaft 712, spiral blade 713, and crushing teeth 706 to rotate, thus achieving tea leaf crushing and extract agitation; friction block 710 and extrusion roller 709 work together to enhance mixing effect; preliminary filter screen 8 and tertiary filter screen... 9. Multi-stage filtration is achieved, with the drainage shell 4, drainage pipe 6, and anti-loosening plate 5 ensuring stable and leak-free liquid flow; the adsorption column 10 completes purification, and the extract delivery pipe 104, sealing plate 206, and drain elbow deliver the purified liquid to the storage tank 201; the storage tank 201 is quickly positioned and sealed with the sealing plate 206 by the stabilizing pin 207, locking ring 203, extrusion protrusion 204, positioning bolt 205, and the sealing plate 206; the support plate 301, first positioning rod 302, connecting plate 303, locking plate 304, sealing plug 305, and second positioning rod 306 ensure the sealing of the storage tank 201, ultimately achieving efficient separation and purification of tea pigments; To clean the filter screen, open the corresponding valve installed later to discharge tea residue and waste liquid. When disassembling storage tank 201, rotate the locking ring 203 at the bottom of storage tank 201 in the opposite direction to disengage the squeezing protrusion 204 from the annular groove of the stabilizing pin 207, and lift storage tank 201 upwards to complete disassembly. If you need to take the purified liquid, refer to the above steps to unlock the sealing plug 305 again. The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
