Description

Technical Field

[0001] This invention relates to the field of theaflavin processing technology, and more specifically, to a sieving device for purifying theaflavin in tea leaves. Background Technology

[0002] Theaflavins in tea leaves are a yellow natural pigment found in tea. During tea processing, appropriate equipment is often used to extract theaflavins so that they can be used in various fields such as food and cosmetics. In the process of theaflavins processing, organic solvents such as ethyl acetate and ethanol are generally used to extract theaflavins from the tea leaves. Then, the extract is dissolved in water and crystallized under high temperature and high pressure.

[0003] Before and after this step, corresponding sieving devices are used to remove solid impurities or precipitates from the extract. However, most existing sieving devices are independent equipment, and the extract needs to be transferred before filtration. The transfer process usually takes a lot of time, which will prolong the purification process of theaflavins to a certain extent and thus affect the overall processing efficiency of tea. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a sieving device for the purification of theaflavins in tea leaves. This device allows the filter components to be adjusted in position according to actual needs, enabling direct filtration and sieving of the extract, saving time spent during transport, and thus shortening the overall processing progress of tea. Furthermore, the device can agitate the crystals using a dispersing disc to prevent their accumulation and blockage of the connecting pipe, ensuring that the crystals can be discharged normally and guaranteeing the normal processing of theaflavins. In addition, it enables quick disassembly and assembly of the filter plate for cleaning or unified treatment of collected solid impurities, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sieving device for purifying theaflavins in tea leaves, comprising a high-temperature and high-pressure processing tank, wherein the top and bottom of the high-temperature and high-pressure processing tank are provided with connecting pipes, and the sieving device for purifying theaflavins in tea leaves further includes...

[0010] In a preferred embodiment, the device further includes an electric push rod three, which is disposed on one side of the connecting seat two along its length. The top end of the electric push rod three is fixedly connected to a connecting plate two, and the bottom of the connecting plate two is fixedly installed with a fixing post. The surface of the fixing post is movably connected to the interior of the connecting seat two, and the bottom end of the fixing post is engaged with the end of the mounting rod near the connecting seat two along its length.

[0011] In a preferred embodiment, a filter assembly is also included, which is disposed at the top of the high-temperature and high-pressure treatment tank.

[0012] In a preferred embodiment, the filtration assembly includes a filter tank body, a connecting pipe, a second motor, a first gear, a second gear, a shield, a connecting rod, and a dispersing disc. The connecting pipe is respectively disposed at the top and bottom of the filter tank body. The second motor is disposed at the top of the filter tank body, and the drive shaft of the second motor is fixedly connected to the top of the first gear. The outer edge of the first gear meshes with the outer edge of the second gear. The shield is fixedly connected to the top of the inner cavity of the filter tank body, and the drive shaft of the second motor is rotatably connected to the surface of the shield. The connecting rod is fixedly connected to the top of the second gear, and the surface of the connecting rod is fixedly connected to the interior of the dispersing disc. The surface of the connecting rod is rotatably connected to the center position of the top of the shield. The surface of the connecting pipe is sleeved with the interior of the connecting pipe.

[0013] In a preferred embodiment, the system further includes a sealing ring and a weighting pad. The two sealing rings are respectively disposed around the periphery of the two connecting pipes. The weighting pad is fixedly connected to the bottom of the filter tank body. The inner ring of the sealing ring is in contact with the periphery of the connecting pipe.

[0014] In a preferred embodiment, a mounting assembly is also included, which is disposed outside the filter tank body.

[0015] In a preferred embodiment, the mounting assembly includes a mounting ring, a side plate, a spring, a movable plate, a fixing rod, a mounting bracket, and a filter plate. The mounting ring is fixedly connected to the outer surface of the filter tank body. The side plate is disposed opposite to the surface of the mounting ring. One end of the spring is fixedly connected to the inside of the side plate, and the other end of the spring is fixedly connected to the surface of the movable plate. The fixing rod is fixedly connected to the side of the movable plate near the side plate, and the surface of the fixing rod is movably connected to the inside of the side plate. The inner wall of the mounting bracket is fixedly connected to one side of the filter plate surface. The surface of the mounting bracket fits against the inside of the mounting ring.

The surface of the mounting ring is fixedly connected to the end of the mounting rod away from the connecting seat.

[0016] The technical effects and advantages of this invention are as follows:

[0017] This invention utilizes the retraction of an electric push rod two to move a fixing pin horizontally, disengaging the fixing pin from the mounting column. An electric push rod three, located on the back of the connecting seat two, extends, causing the fixing column to move upwards and disengage from the mounting rod. At this point, both the mounting rod and the mounting column are movable. A motor one drives the connecting seat one to rotate, causing the mounting column to rotate synchronously. This allows the filter tank body to rotate around the high-temperature, high-pressure treatment tank. When the filter tank body rotates to below the high-temperature, high-pressure treatment tank, the electric push rod one extends, connecting the filter tank body to the high-temperature, high-pressure treatment tank via a connecting pipe at the bottom of the tank. The mounting column and mounting rod are then fixed by the fixing pin and the fixing column. After crystallization, the filter can be filtered again through the filter assembly. This allows the filter assembly to be adjusted in position according to actual needs, directly filtering and sieving the extract, saving time during transport and shortening the overall tea processing time, thus improving the practicality of the device.

[0018] This invention uses a second motor to drive a first gear to rotate, enabling the second gear to rotate synchronously. This allows the connecting rod connected to the top of the second gear, along with the dispersing disc, to rotate at the top of the filter tank body. Therefore, when the filter tank body is located at the bottom of the high-temperature and high-pressure processing tank, the crystals can be stirred by the dispersing disc to prevent them from accumulating and causing blockage of the connecting pipe, ensuring that the crystals can be discharged normally and guaranteeing the normal processing of theaflavins.

[0019] This invention moves the movable plate horizontally outward from the side plate, causing the spring to deform and the fixed rod connected to the surface of the movable plate to move synchronously. This disengages the movable plate from the mounting frame and the interior of the side plate. At this point, the mounting frame, along with the filter plate, can be moved horizontally to separate and disassemble it from the interior of the filter tank body. This allows for quick assembly and disassembly of the filter plate for cleaning or unified treatment of collected solid impurities, thereby improving the practicality of the device.

[0032] Connecting seat 2 8 is movably connected to the top of mounting column 6, and the bottom of connecting seat 2 8 is fixedly connected to the top of electric push rod 1 7. The mounting rod 9 is rotatably connected inside connecting seat 2 8.

[0033] A sliding sleeve 10 is slidably connected to the surface of the mounting post 6. A connecting plate 11 is fixedly installed on the surface of the sliding sleeve 10. A sleeve ring 12 is fixedly connected to the connecting plate 11. The inside of the sleeve ring 12 is sleeved with the surface of the mounting rod 9. Through the sliding sleeve 10, in conjunction with the connecting plate 11 and the sleeve ring 12, a relatively stable triangular structure can be formed between the mounting rod 9 and the mounting post 6, thereby improving the overall stability of the mounting rod 9. Furthermore, the inner wall of the sliding sleeve 10 is made rough, which can increase the friction when in contact with the surface of the mounting post 6, further improving the stability of the mounting rod 9.

[0034] In a preferred embodiment, the device further includes an electric push rod 2 13, which is disposed on the surface of the motor 1 4. One end of the electric push rod 2 13 is fixedly connected to a mounting plate 14. The interior of the mounting plate 14 is rotatably connected to the surface of the drive shaft of the motor 1 4. A fixing pin 15 is disposed opposite to the surface of the mounting plate 14. The surface of the fixing pin 15 engages with a groove opened on the bottom surface of the mounting post 6.

[0035] In a preferred embodiment, the device further includes an electric push rod 3 16, which is disposed on one side of the length direction of the connecting seat 2 8. The top end of the electric push rod 3 16 is fixedly connected to the connecting plate 2 17, and the bottom of the connecting plate 2 17 is fixedly installed with a fixing post 18. The surface of the fixing post 18 is movably connected to the interior of the connecting seat 2 8, and the bottom end of the fixing post 18 is engaged with the end of the mounting rod 9 near the connecting seat 2 8 in the length direction.

[0036] In a preferred embodiment, a filter assembly 19 is also included, which is disposed on the top of the high-temperature and high-pressure treatment tank 1.

The connecting pipe 192 is respectively disposed at the top and bottom of the filter tank body 191. The second motor 195 is disposed at the top of the filter tank body 191. The drive shaft of the second motor 195 is fixedly connected to the top of the first gear 196. The outer edge of the first gear 196 meshes with the outer edge of the second gear 197. The shield 198 is fixedly connected to the top of the inner cavity of the filter tank body 191. The drive shaft of the second motor 195 is connected to the outer edge of the shield 198. The connecting rod 199 is fixedly connected to the top of the gear 197. The surface of the connecting rod 199 is fixedly connected to the inside of the dispersion disk 1910. The surface of the connecting rod 199 is rotatably connected to the center of the top of the shield 198. The surface of the connecting pipe 192 is sleeved with the inside of the connecting pipe 2. Through the shield 198 structure, the gear 196 and gear 197 can be shielded to prevent the extract from being in contact with them for a long time, which would affect their normal use. In addition, its surface is inclined, so it can play a certain guiding role for the extract, allowing it to fall into the filter plate 207 set in the filter tank body 191 for filtration and screening.

[0038] In a preferred embodiment, the system further includes a sealing ring 193 and a weighting pad 194. The two sealing rings 193 are respectively disposed around the two connecting pipes 192. The weighting pad 194 is fixedly connected to the bottom of the filter tank body 191. The inner ring of the sealing ring 193 fits against the outer periphery of the connecting pipe 2. Through the structure of the weighting pad 194, the center of gravity of the filter tank body 191 can be lowered, so that it can always maintain a vertical state when rotating, so as to connect with the connecting pipe 2 at the bottom of the high temperature and high pressure treatment tank 1 for secondary filtration and screening, thereby saving transfer time.

[0039] In a preferred embodiment, a mounting assembly 20 is also included, which is disposed outside the filter tank body 191.

[0040] In a preferred embodiment, the mounting assembly 20 includes a mounting ring 201, a side plate 202, a spring 203, a movable plate 204, a fixing rod 205, a mounting bracket 206, and a filter plate 207. The mounting ring 201 is fixedly connected to the outer surface of the filter tank body 191. The side plate 202 is disposed opposite to the surface of the mounting ring 201. One end of the spring 203 is fixedly connected to the inside of the side plate 202, and the other end of the spring 203 is fixedly connected to the surface of the movable plate 204. The fixing rod 205 is fixedly connected to the side of the movable plate 204 near the side plate 202, and the surface of the fixing rod 205 is movably connected to the inside of the side plate 202. The inner wall of the mounting bracket 206 is fixedly connected to one side of the surface of the filter plate 207. The surface of the mounting bracket 206 is in contact with the inside of the mounting ring 201. The end of the fixing rod 205 away from the movable plate 204 is engaged with the side of the mounting bracket 206. The surface of the mounting ring 201 is fixedly connected to the end of the mounting rod 206 away from the connecting seat 8.

[0041] Working principle of the invention: After the extract is filtered by the filter assembly 19, it is introduced into the high-temperature and high-pressure treatment tank 1 through the connecting pipe 192 at the bottom of the filter tank body 191. Then, the electric push rod 7, which is set inside the mounting column 6, extends and drives the filter assembly 19 to move upward, so that the connecting pipe 192 is separated from the connecting pipe 2 at the top of the high-temperature and high-pressure treatment tank 1. At this time, the extract is crystallized by the high-temperature and high-pressure treatment tank 1, and the electric push rod 13 retracts and drives the fixing pin 15 to move horizontally, so that the fixing pin 15 is separated from the mounting column 6. The electric push rod 16, which is set on the back of the connecting seat 8, extends and drives the fixing column 18 to move upward. It then detaches from the interior of the mounting rod 9. At this time, both the mounting rod 9 and the mounting column 6 are in a movable state. The motor 4 drives the connecting seat 5 to rotate, so the mounting column 6 rotates synchronously, allowing the filter tank body 191 to rotate around the high temperature and high pressure treatment tank 1. When the filter tank body 191 rotates to the bottom of the high temperature and high pressure treatment tank 1, the electric push rod 7 extends, allowing the filter tank body 191 to connect to the high temperature and high pressure treatment tank 1 through the connecting pipe 2 at the bottom of the high temperature and high pressure treatment tank 1. The mounting column 6 and the mounting rod 9 are fixed by the fixing pin 15 and the fixing column 18. After crystallization is completed, the filter can be filtered again through the filter assembly 19.

[0042] Motor 2 195 drives gear 196 to rotate, which enables gear 2 197 to rotate synchronously. As a result, the connecting rod 199 connected to the top of gear 2 197, together with the dispersing disc 1910, can rotate accordingly on the top of the filter tank body 191.

[0043] When it is necessary to disassemble the filter plate 207, the movable plate 204 is moved horizontally outward of the side plate 202, causing the spring 203 to deform, and the fixing rod 205 connected to the surface of the movable plate 204 moves synchronously. This disengages the mounting bracket 206 and the interior of the side plate 202, allowing the mounting bracket 206 and the filter plate 207 to be moved horizontally and separated from the interior of the filter tank body 191.

[0044] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
