Description

Technical Field

[0001] This utility model relates to the field of dark tea processing technology, and in particular to a purification mechanism for dark tea processing. Background Technology

[0002] Dark tea is a unique type of tea in China, belonging to post-fermented tea, with a long history and rich cultural background. The raw material for dark tea is usually coarser, older tea leaves, which undergo a specific microbial fermentation process, ultimately resulting in a dark brown color and mellow taste. The processing of dark tea typically involves impurity removal.

[0003] In the existing Chinese utility model patent application, CN202322557032.9 discloses a purification device for tea processing, comprising a cylindrical body. The bottom of the cylindrical body is mounted on a mounting base via a rotating device. A sealing cover is coaxially connected to one end of the cylindrical body, and a drive motor is coaxially connected to the sealing cover. A connecting inner tube is coaxially provided inside the cylindrical body, and the output end of the drive motor is coaxially connected to one end of the connecting inner tube. Several through holes are formed on the outer wall of the connecting inner tube. An annular end plate is coaxially connected to the other end of the connecting inner tube, and an annular locking block is coaxially connected to one side of the annular end plate. An annular locking groove is coaxially provided at the other end of the cylindrical body, and the annular locking block is coaxially connected to the annular locking groove. A conical feed pipe is sealed and connected to the other end of the cylindrical body, and the conical feed pipe is coaxially connected to the outer wall of the cylindrical body. A discharge port is formed at the bottom of the cylindrical body, and a discharge pipe is fixedly connected to the bottom of the discharge port. This utility model facilitates the feeding and discharging of tea leaves and improves the efficiency of purification.

[0004] Referring to the aforementioned impurity removal device for tea processing, this device uses the rotation of the inner tube to drive the tea leaves in a swirling sieve. However, during this swirling sieve process, the tea leaves tend to accumulate at the bottom of the inner tube, potentially causing some leaves to clump together and trapping impurities, making them difficult to separate effectively. Furthermore, the through-holes in the inner tube may become clogged by the separated impurities, affecting the sieve efficiency. Therefore, effectively sieving and removing impurities from dark tea while preventing clogging of the through-holes is a crucial issue that needs to be addressed in the design of impurity removal mechanisms for dark tea processing. Utility Model Content

[0005] This invention provides a purification mechanism for black tea processing to solve the problems of tea leaves clumping together, preventing impurities from being effectively screened out, and the clogging of the sieved holes by impurities.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a purification mechanism for black tea processing, including a black tea processing purification shell, and further comprising:

[0008] A sieving structure for removing impurities is provided inside the impurity removal shell used in black tea processing.

[0009] A striking structure is provided above a waste removal screening structure, and the rotation of the waste removal screening structure synchronously drives the striking structure to strike.

[0010] A buffer guiding structure is disposed inside the impurity removal screening structure.

[0011] Preferably, a support base is fixedly connected to the bottom side wall of the black tea processing and impurity removal shell, support rings are fixedly connected to the inner side walls at both ends of the black tea processing and impurity removal shell, threaded rings are fixedly connected to the side walls of the black tea processing and impurity removal shell, a cap is internally threaded onto the threaded ring, a handle is fixedly connected to the side wall of the cap, a discharge pipe is fixedly connected to the bottom of the impurity removal shell, and the bottom side wall of the black tea processing and impurity removal shell is inclined toward the discharge pipe.

[0012] In this technical solution, the discharge pipe discharges the impurities that have been screened out.

[0013] Preferably, a baffle frame is fixedly connected to the inner sidewalls on both sides of the black tea processing and impurity removal shell, and activated carbon is placed inside the baffle frame. A shielding door is rotatably connected to the sidewalls on both sides of the black tea processing and impurity removal shell, and a fixing buckle one is fixedly connected to the sidewall of the shielding door. A fixing buckle two is fixedly connected to the sidewalls on both sides of the black tea processing and impurity removal shell, and the fixing buckle two and the fixing buckle one cooperate with each other.

[0014] In this technical solution, activated carbon can adsorb odors inside the black tea processing and impurity removal shell, preventing odors from existing inside the shell. During black tea processing, odors are adsorbed by the black tea. When the activated carbon needs to be replaced, separate the fixing clip one and fixing clip two, open the cover door, and the activated carbon can be taken out for replacement.

[0015] Preferably, the impurity removal screening structure includes a screening cylinder, a pusher plate, a baffle plate, a connecting ring block, and ball bearings. The two ends of the screening cylinder are fixedly connected to the connecting ring block, which is rotatably connected to the support ring. Ball bearings are rotatably connected at equal intervals inside the side wall of the connecting ring block, and the ball bearings abut against the side wall of the support ring. The pusher plate is fixedly connected at equal intervals on the outer side wall of the screening cylinder, and the baffle plate is fixedly connected at equal intervals on the inner side wall of the screening cylinder.

[0016] In this technical solution, the rotation of the connecting ring block drives the sieving cylinder and the ball bearings to rotate. The ball bearings roll on the support ring, which makes the rotation of the connecting ring block smoother. The rotation of the sieving cylinder causes the black tea inside to continuously roll and be sieve. The rotation of the sieving cylinder drives the push plate and the baffle to rotate.

[0017] Preferably, the number of push plates and baffles are the same, the positions of the push plates and baffles correspond to each other, and the side wall of the connecting ring block is provided with a rotating tooth groove.

[0018] In this technical solution, the corresponding positions of the push plate and the baffle can reduce the area of ​​the sidewalls that are blocked by the corresponding positions of the push plate and the baffle.

[0019] Preferably, the impurity removal screening structure includes a rotating gear, a rotating rod, and a rotating motor. The rotating motor is fixedly connected to the side wall of the black tea processing impurity removal shell. The rotating end of the rotating motor is fixedly connected to the rotating rod, and the other end of the rotating rod extends into the black tea processing impurity removal shell and is fixedly connected to the rotating gear. The rotating gear and the rotating tooth groove mesh with each other.

[0020] In this technical solution, the rotation of the motor drives the rotation of the rotating rod, which in turn drives the rotation of the rotating gear. The rotating gear rotates within the rotating tooth groove, which in turn drives the connecting ring block to rotate.

[0021] Preferably, the buffer guide structure includes a buffer guide plate, a second fixed rod, a second rotating sleeve, and a second torsion spring. The buffer guide plate and the second fixed rod are fixedly connected to the inner wall of the black tea processing and impurity removal shell. The buffer guide plate is inclined towards the center and is staggered with each other. The second rotating sleeve is rotatably connected to the second fixed rod. The second rotating sleeve is fixedly connected to the bottom side wall of the buffer guide plate. The second torsion spring is fixedly connected between the second rotating sleeve and the inner wall of the black tea processing and impurity removal shell.

[0022] In this technical solution, the buffer guide plate catches the falling black tea and guides it downward, reducing the angle of the falling black tea and thus reducing the impact of the black tea falling back to the bottom.

[0023] Preferably, the closest distance between the end of the buffer guide plate and the side wall of the screening cylinder is less than the height of the baffle.

[0024] In this technical solution, when the baffle passes the end of the buffer guide plate, it pushes one end of the buffer guide plate to rise, and the second torsion spring twists. After rising a short distance, the baffle leaves the buffer guide plate, and the second torsion spring causes the buffer guide plate to fall again, colliding with the buffer pad and causing a small vibration. This causes the buffer guide plate to vibrate continuously under the push of the baffle, so that the black tea falling on the buffer guide plate can slide down better.

[0025] Preferably, a fixing rod three is fixedly connected to the inner side wall of the black tea processing and impurity removal shell, and a buffer pad is fixedly connected to the top of the fixing rod three. The buffer pad is attached to the bottom side wall of the buffer guide plate.

[0026] Preferably, the striking structure includes a fixed rod, a rotating sleeve, a fixed plate, a connecting plate, a striking rod, a fixed block, and a torsion spring. The fixed block is fixedly connected to the top inner wall of the black tea processing and impurity removal shell. A fixed rod is fixedly connected between the fixed block and the inner walls at both ends of the black tea processing and impurity removal shell. A rotating sleeve is rotatably connected to the fixed rod. A torsion spring is fixedly connected between the rotating sleeve and the fixed block. A fixed plate and a connecting plate are fixedly connected to the side wall of the rotating sleeve. The striking rod is fixedly connected to the other end of the connecting plate. The distance between the fixed plate and the side wall of the sieving cylinder is less than the height of the pushing plate.

[0027] In this technical solution, when the push plate rotates past the fixed plate, it pushes the fixed plate to move. The fixed plate drives the rotating sleeve to rotate, and the rotating sleeve drives the connecting plate to rotate. The torsion spring twists, and the connecting plate drives the striking rod to rise. When the push plate leaves the fixed plate, the previous push plate also passes over the striking rod and moves in front of the striking rod. At this time, the torsion spring drives the striking rod to fall sharply and strike the screening cylinder, causing the screening cylinder to vibrate, thereby effectively shaking out the debris blocking the screen cylinder.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows:

[0030] 1. The rotating motor drives the sieving cylinder to rotate, causing the black tea inside to continuously tumble and sieve. The rotation of the sieving cylinder also drives the baffle to rotate, causing some of the black tea to move upwards. When the baffle moves the black tea to the upper part, it slides downwards and falls. The buffer guide plate in the middle catches the falling black tea and guides it downwards, slowing down the angle of the fall and reducing the impact of the black tea falling back to the bottom. The black tea is constantly being moved upwards and then falling, causing the black tea inside the sieving cylinder to be constantly turned over. This facilitates better sieving and impurity removal of the black tea, while preventing the black tea from clumping together during the sieving process, which would trap impurities and prevent them from being effectively sieved.

[0031] 2. When the baffle passes the end of the buffer guide plate, it will push one end of the buffer guide plate to rise. The second torsion spring will twist and rise a short distance. After that, the baffle will leave the buffer guide plate. The second torsion spring will drive the second buffer guide plate to fall again and collide with the buffer pad, causing a small vibration. This will make the buffer guide plate vibrate continuously under the push of the baffle, so that the black tea falling on the buffer guide plate will slide down better.

[0032] 3. When the push plate rotates past the fixed plate, it pushes the fixed plate to move. The fixed plate drives the rotating sleeve to rotate, and the rotating sleeve drives the striking rod to rise. When the push plate leaves the fixed plate, the torsion spring drives the striking rod to fall sharply and strike the screening cylinder, causing the screening cylinder to vibrate. This facilitates the removal of debris that is blocked in the screen of the screening cylinder, preventing debris from clogging the mesh and affecting the screening effect of the screening cylinder.

[0039] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0040] like Figure 1-4 As shown, the impurity removal mechanism for black tea processing includes a black tea processing impurity removal housing 1, and further includes:

[0041] Impurity removal screening structure 3 is installed inside the impurity removal shell 1 for black tea processing;

[0042] The striking structure 4 is disposed above the impurity removal screening structure 3. The rotation of the impurity removal screening structure 3 synchronously drives the striking structure 4 to strike.

[0043] The buffer guide structure 13 is disposed inside the impurity removal screening structure 3.

[0044] A support base 2 is fixedly connected to the bottom side wall of the black tea processing and impurity removal housing 1. Support rings 7 are fixedly connected to the inner side walls at both ends of the black tea processing and impurity removal housing 1. Threaded rings 16 are fixedly connected to the side walls of the black tea processing and impurity removal housing 1. A cap 5 is internally threaded to the threaded ring 16. A handle 6 is fixedly connected to the side wall of the cap 5. A discharge pipe 17 is fixedly connected to the bottom of the impurity removal housing. The bottom side wall of the black tea processing and impurity removal housing 1 is inclined towards the discharge pipe 17.

[0045] The discharge pipe 17 discharges the impurities that have been screened out.

[0046] A baffle frame 12 is fixedly connected to the inner sidewalls on both sides of the black tea processing and impurity removal shell 1. Activated carbon 11 is placed inside the baffle frame 12. A shielding door 8 is rotatably connected to the sidewalls on both sides of the black tea processing and impurity removal shell 1. A fixing buckle 1 9 is fixedly connected to the sidewall of the shielding door 8. A fixing buckle 2 10 is fixedly connected to the sidewalls on both sides of the black tea processing and impurity removal shell 1. The fixing buckle 2 10 and the fixing buckle 1 9 cooperate with each other.

[0047] Activated carbon 11 can absorb odors inside the black tea processing and impurity removal shell 1, preventing odors from existing inside the black tea processing and impurity removal shell 1. During black tea processing, odors are absorbed by the black tea. When it is necessary to replace activated carbon 11, separate the fixing buckle 1 9 and the fixing buckle 2 10, and open the shielding door 8 to take out activated carbon 11 for replacement.

[0048] The impurity removal screening structure 3 includes a screening cylinder 301, a pusher plate 302, a baffle plate 303, a connecting ring block 304, and ball bearings 305. The two ends of the screening cylinder 301 are fixedly connected to the connecting ring block 304, which is rotatably connected to the support ring 7. Ball bearings 305 are rotatably connected at equal intervals inside the side wall of the connecting ring block 304, and the ball bearings 305 abut against the side wall of the support ring 7. The pusher plate 302 is fixedly connected at equal intervals on the outer side wall of the screening cylinder 301, and the baffle plate 303 is fixedly connected at equal intervals on the inner side wall of the screening cylinder 301.

[0049] The rotation of the connecting ring block 304 drives the sieving cylinder 301 and the ball bearing 305 to rotate. The ball bearing 305 rolls on the support ring 7, which makes the rotation of the connecting ring block 304 smoother. The rotation of the sieving cylinder 301 causes the black tea inside to continuously roll and be sieved. The rotation of the sieving cylinder 301 drives the push plate 302 and the baffle 303 to rotate.

[0050] The number of push plates 302 and baffles 303 is the same, and the positions of push plates 302 and baffles 303 correspond to each other. Rotational tooth grooves 321 are provided on the side wall of the connecting ring block 304.

[0051] The corresponding positions of the push plate 302 and the baffle 303 can reduce the area of ​​the sidewalls that are blocked by the corresponding positions of the push plate 302 and the baffle 303.

[0052] The impurity removal screening structure 3 includes a rotating gear 311, a rotating rod 312, and a rotating motor 313. The rotating motor 313 is fixedly connected to the side wall of the black tea processing impurity removal shell 1. The rotating end of the rotating motor 313 is fixedly connected to the rotating rod 312. The other end of the rotating rod 312 extends into the black tea processing impurity removal shell 1 and is fixedly connected to the rotating gear 311. The rotating gear 311 and the rotating tooth groove 321 mesh with each other.

[0053] The rotating motor 313 rotates, causing the rotating rod 312 to rotate. The rotating rod 312 drives the rotating gear 311 to rotate. The rotating gear 311 rotates within the rotating tooth groove 321, causing the connecting ring block 304 to rotate.

[0054] The buffer guide structure 13 includes a buffer guide plate 1301, a second fixing rod 1302, a second rotating sleeve 1303, and a second torsion spring 1304. The buffer guide plate 1301 and the second fixing rod 1302 are fixedly connected to the inner wall of the black tea processing and impurity removal shell 1. The buffer guide plate 1301 is inclined towards the middle and is staggered with each other. The second rotating sleeve 1303 is rotatably connected to the second fixing rod 1302. The second rotating sleeve 1303 is fixedly connected to the bottom side wall of the buffer guide plate 1301. The second torsion spring 1304 is fixedly connected between the second rotating sleeve 1303 and the inner wall of the black tea processing and impurity removal shell 1.

[0055] The buffer guide plate 1301 catches the falling black tea and guides it downward, slowing down the angle of the falling black tea, thereby reducing the impact of the black tea falling back to the bottom.

[0056] The closest distance between the end of the buffer guide plate 1301 and the side wall of the screening cylinder 301 is less than the height of the baffle 303.

[0057] When the baffle 303 passes the end of the buffer guide plate 1301, it will push one end of the buffer guide plate 1301 to rise. The second torsion spring 1304 will twist and rise a short distance. Then the baffle 303 will leave the buffer guide plate 1301. The second torsion spring 1304 will drive the buffer guide plate 1301 to fall again and collide with the buffer pad 15, causing a small vibration. This makes the buffer guide plate 1301 vibrate continuously under the push of the baffle 303, so that the black tea falling on the buffer guide plate 1301 can slide down better.

[0058] A fixing rod 14 is fixedly connected to the inner side wall of the black tea processing and impurity removal shell 1. A buffer pad 15 is fixedly connected to the top of the fixing rod 14. The buffer pad 15 is attached to the bottom side wall of the buffer guide plate 1301.

[0059] The striking structure 4 includes a fixed rod 401, a rotating sleeve 402, a fixed plate 403, a connecting plate 404, a striking rod 405, a fixed block 406, and a torsion spring 407. The fixed block 406 is fixedly connected to the top inner wall of the black tea processing and impurity removal housing 1. The fixed rod 401 is fixedly connected between the fixed block 406 and the inner walls at both ends of the black tea processing and impurity removal housing 1. The fixed rod 401 is rotatably connected to the rotating sleeve 402. The torsion spring 407 is fixedly connected between the rotating sleeve 402 and the fixed block 406. The fixed plate 403 and the connecting plate 404 are fixedly connected to the side wall of the rotating sleeve 402. The striking rod 405 is fixedly connected to the other end of the connecting plate 404. The distance between the fixed plate 403 and the side wall of the sieve cylinder 301 is less than the height of the push plate 302.

[0060] When the push plate 302 rotates past the fixed plate 403, it pushes the fixed plate 403 to move. The fixed plate 403 drives the rotating sleeve 402 to rotate, and the rotating sleeve 402 drives the connecting plate 404 to rotate. The torsion spring 407 twists, and the connecting plate 404 drives the striking rod 405 to rise. When the push plate 302 leaves the fixed plate 403, the previous push plate 302 also passes over the striking rod 405 and moves in front of the striking rod 405. At this time, the torsion spring 407 drives the striking rod 405 to fall sharply and strike the screening cylinder 301, causing the screening cylinder 301 to vibrate, thereby effectively shaking out the debris blocked in the screen cylinder 301.

[0061] In use, all electrical components mentioned in this application are connected to an external power supply and control switch. Activated carbon 11 can adsorb the odor inside the black tea processing and impurity removal shell 1, preventing the presence of odor inside the black tea processing and impurity removal shell 1. When the activated carbon 11 needs to be replaced, separate the fixing buckle 1 9 and the fixing buckle 2 10, open the shielding door 8, and take out the activated carbon 11 for replacement. Remove the cover 5, open the black tea processing and impurity removal shell 1, pour the black tea that needs to be screened into the screening cylinder 301, and then put the cover 5 back on.

[0062] The rotating motor 313 rotates, driving the rotating rod 312 to rotate. The rotating rod 312 drives the rotating gear 311 to rotate. The rotating gear 311 rotates in the rotating tooth groove 321, driving the connecting ring block 304 to rotate. The rotating connecting ring block 304 drives the screening cylinder 301 and the ball bearing 305 to rotate. The ball bearing 305 rolls on the support ring 7, which makes the rotation of the connecting ring block 304 smoother. The rotation of the screening cylinder 301 causes the black tea inside to continuously roll and screen. The rotation of the screening cylinder 301 drives the push plate 302 and the baffle 303 to rotate.

[0063] The rotation of baffle 303 causes some of the black tea to move upwards. Baffle 303 moves the black tea to the upper part, and the angle of baffle 303 is tilted downwards, causing the black tea to slide down. The buffer guide plate 1301 in the middle catches the falling black tea and guides it downwards, reducing the angle of the black tea's fall and thus reducing the impact of the black tea falling back to the bottom. The black tea is constantly being moved to the top and then falling, so that the black tea in the screening cylinder 301 is constantly turned over, preventing the black tea from clumping together during the rolling screening process, which would cause impurities to be trapped inside and unable to be screened out properly.

[0064] When the baffle 303 passes the end of the buffer guide plate 1301, it will push one end of the buffer guide plate 1301 to rise. The second torsion spring 1304 will twist and rise a short distance. After that, the baffle 303 will leave the buffer guide plate 1301. The second torsion spring 1304 will drive the buffer guide plate 1301 to fall again and collide with the buffer pad 15, causing a small vibration. This makes the buffer guide plate 1301 vibrate continuously under the push of the baffle 303, so that the black tea falling on the buffer guide plate 1301 can slide down better.

[0065] When the push plate 302 rotates past the fixed plate 403, it pushes the fixed plate 403 to move. The fixed plate 403 drives the rotating sleeve 402 to rotate, and the rotating sleeve 402 drives the connecting plate 404 to rotate. The torsion spring 407 twists, and the connecting plate 404 drives the striking rod 405 to rise. When the push plate 302 leaves the fixed plate 403, the previous push plate 302 also passes over the striking rod 405 and moves in front of the striking rod 405. At this time, the torsion spring 407 drives the striking rod 405 to fall sharply and strike the screening cylinder 301, causing the screening cylinder 301 to vibrate. This effectively shakes out the debris blocking the screen in the screening cylinder 301, preventing the debris from clogging the screen and affecting the screening effect of the screening cylinder 301.
