Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of separation devices, and particularly relates to an efficient cleaning device for separating camellia oleifera fruit and pulp seeds. BACKGROUND

[0002] Camellia oleifera fruit shelling is a key link in camellia oil processing. The structure is composed of an outer shell and an internal tea seed, wherein the tea seed (including shell and kernel) is an oil pressing raw material, and the shell does not contain oil and is rich in lignin, tannin and other components, which will interfere with the quality of oil, and therefore must be effectively removed. Traditional shelling relies on manual work: after fresh fruit is picked, it is often piled and soaked for 3-5 days to promote after-ripening, so that the shell cracks, and then it is spread and dried and the shell and seed are manually separated, which is low in efficiency.

[0003] Although various mechanical shelling equipment has improved production efficiency at present, there are still problems of low tea seed cleaning rate and incomplete shell-seed separation, and a large amount of manual sorting is still required, which is time-consuming and labor-intensive.

[0025] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0026] In order to make the above-mentioned objects, features and advantages of the application more obvious and easy to understand, the application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] Reference Figures 1 to 6As shown, the present application provides a high-efficiency cleaning device for separating camellia fruit and pulp seeds, which comprises: a drying and puffing box 1 for drying and puffing the camellia fruit, a top end of the drying and puffing box 1 being fixedly connected with a feeding hopper 2, and a discharge guide plate 3 being fixedly connected with a discharge port of the drying and puffing box 1; a first transfer mechanism being obliquely arranged, a low end of the first transfer mechanism being located at the discharge port of the drying and puffing box 1; an extrusion mechanism being arranged below a high end of the first transfer mechanism, the extrusion mechanism being used for extruding the camellia fruit after drying and puffing; a second transfer mechanism being obliquely arranged, a low end of the second transfer mechanism being located below a discharge port of the extrusion mechanism; and a pulp seed separation mechanism being arranged below a high end of the second transfer mechanism, the pulp seed separation mechanism being used for screening and separating the camellia fruit after extrusion.

[0028] Firstly, the camellia fruit is put into the drying and puffing box 1 for heating and drying, so that the fruit pulp shrinks and is preliminarily separated from the tea seeds; the camellia fruit after drying and puffing falls from the discharge port of the drying and puffing box 1 to the low end of the obliquely arranged first transfer mechanism, and is conveyed upward by the first transfer mechanism; when the camellia fruit is transported to the high end of the first transfer mechanism, it falls into the extrusion mechanism arranged below the high end, the mechanism applies pressure to the fruit, so that the fruit pulp is further broken and separated from the tea seeds; the mixture after extrusion falls from the discharge port of the extrusion mechanism to the low end of the obliquely arranged second transfer mechanism, and is conveyed upward by the second transfer mechanism; after the material is conveyed to the high end of the second transfer mechanism, it falls into the pulp seed separation mechanism arranged below the high end, the mechanism realizes large-scale separation of the tea seeds from the fruit pulp fragments through screening, and further finely screens the tea seeds to realize the final separation of the tea seeds from the fine impurities and residues. The whole process realizes continuous and automatic operation.

[0029] The pretreatment of the drying and puffing box 1 creates conditions for subsequent mechanical separation, the fruit pulp is made brittle by drying, the extrusion energy consumption is reduced, and the stripping efficiency is improved; the obliquely arranged first transfer mechanism and second transfer mechanism constitute two-stage lifting conveying lines, which not only complete the automatic flow transfer of the material between processes, but also utilize the gravity to assist the movement of the material by the inclination angle, thereby reducing the blockage; the specially arranged extrusion mechanism applies mechanical force to the camellia fruit after drying, which can efficiently and completely separate the tea seeds from the fruit pulp, solving the problems of low efficiency and incomplete separation in the traditional manual or simple knocking method; the core pulp seed separation mechanism integrates multiple screening functions, and completes the “pulp-seed” coarse separation and “seed-residue” fine separation in one operation process, greatly improving the purity and acquisition efficiency of the clean tea seeds. The device forms an efficient assembly line through the cooperative operation of the drying and puffing box 1, the first transfer mechanism, the extrusion mechanism, the second transfer mechanism and the pulp seed separation mechanism, realizes the continuity, mechanization and high efficiency of the camellia fruit and pulp seed separation and cleaning process, and significantly improves the production efficiency and cleaning quality.

[0030] Further, the extrusion mechanism comprises an extrusion box 12, a first feeding port 13 is arranged at one end of the top wall of the extrusion box 12, the first feeding port 13 is located below the high end of the first transfer mechanism, the side wall of the end of the extrusion box 12 away from the first feeding port 13 is open, a bottom plate 15 is fixedly connected to the bottom end of the extrusion box 12, the length of the bottom plate 15 is smaller than the length of the top wall of the extrusion box 12, support legs 14 are respectively fixedly connected to the four corners of the bottom end of the bottom plate 15, and an extrusion assembly is arranged in the extrusion box 12.

[0031] Further, the extrusion assembly comprises an upper extrusion part and a lower extrusion part, the upper extrusion part and the lower extrusion part are arranged in the extrusion box 12, a gap is left between the upper extrusion part and the lower extrusion part, the upper extrusion part and the lower extrusion part partially overlap, the non-overlapping part of the lower extrusion part and the upper extrusion part is located below the first feeding port 13, and the non-overlapping part of the upper extrusion part and the lower extrusion part is located above the low end of the second transfer mechanism.

[0032] Further, the upper extrusion part comprises a second motor 16, the second motor 16 is fixedly connected to the inner side wall of the extrusion box 12, one end of the output shaft of the second motor 16 is coaxially fixedly connected with a second driving roller 17, the other end of the second driving roller 17 is rotatably connected with the inner side wall of the extrusion box 12, one end of an upper extrusion belt 19 is transmissionally wound around the outer side of the second driving roller 17, the other end of the upper extrusion belt 19 is transmissionally connected with a second driven roller 18, the two ends of the second driven roller 18 are rotatably connected with the inner side wall of the extrusion box 12, the second driven roller 18 is located in the same horizontal plane as the second driving roller 17, an upper fixed plate 20 is arranged between the upper extrusion belt 19 and the lower extrusion belt 23, and the upper fixed plate 20 is in sliding contact with the upper extrusion belt 19 and the lower extrusion belt 23.

[0033] Further, the lower extrusion part comprises a third motor, the third motor is fixedly connected to the inner side wall of the extrusion box 12, one end of the output shaft of the third motor is coaxially fixedly connected with a third driving roller 21, the other end of the third driving roller 21 is rotatably connected with the inner side wall of the extrusion box 12, one end of a lower extrusion belt 23 is transmissionally wound around the outer side of the third driving roller 21, the other end of the lower extrusion belt 23 is transmissionally connected with a third driven roller 22, the two ends of the third driven roller 22 are rotatably connected with the inner side wall of the extrusion box 12, the third driven roller 22 is located in the same horizontal plane as the third driving roller 21, a lower fixed plate 24 is arranged between the upper extrusion belt 19 and the lower extrusion belt 23, the lower fixed plate 24 is in sliding contact with the upper extrusion belt 19 and the lower extrusion belt 23, and the non-overlapping part of the upper extrusion belt 19 and the lower extrusion belt 23 is located below the first feeding port 13.

[0034] The oil tea fruits treated by the drying and exploding box 1 and transported by the first transfer mechanism fall from the high end of the first transfer mechanism and enter the inside of the extruding mechanism through the first feeding port 13 of the top wall of the extruding box 12 located above. The material first falls into the initial area composed of the upper extruding part and the lower extruding part, which is located below the first feeding port 13 and is the non-overlapping part of the lower extruding belt 23 and the upper extruding belt 19, and the material is accumulated and preliminarily positioned here. After starting, the second motor 16 of the upper extruding part drives the second driving roller 17 to rotate, which drives the upper extruding belt 19 to circulate and drive around the second driven roller 18, at the same time, the upper fixed plate 20 provides sliding support for the upper and lower layers of the upper extruding belt 19, ensuring its smooth operation and forming a rigid support surface for the upper layer of the extruding belt. At the same time, the third motor of the lower extruding part drives the third driving roller 21 to rotate, which drives the lower extruding belt 23 to circulate and drive around the third driven roller 22, and the lower fixed plate 24 provides support for the upper and lower layers of the lower extruding belt 23, ensuring its smooth operation and forming a rigid support surface for the upper layer of the extruding belt. The driving direction of the upper extruding belt 19 and the lower extruding belt 23 is configured to move towards each other in the overlapping area. After the material enters the overlapping area from the feeding area, it is clamped by the lower layer of the upper extruding belt 19 and the upper layer of the lower extruding belt 23 in operation, and is forced to be transported forward between them. In this process, since the gap between the two layers of extruding belts is fixed and smaller than the original size of the oil tea fruits, the material is subjected to continuous and uniform rolling and extruding when passing through, and the fruit and pulp are completely crushed and flattened under mechanical pressure, thereby realizing efficient and powerful separation of tea seeds and fruit pulp. The crushed mixture is conveyed to the other end of the extruding belt, i.e. the other non-overlapping part of the upper extruding belt 19 and the lower extruding belt 23, and the non-overlapping part of the upper extruding belt 19 is located just above the low end of the second transfer mechanism, and the material falls naturally from here and enters the subsequent second transfer mechanism to complete the discharge of the extruding process. The entire extruding box 12 is stably supported by the bottom plate 15 and the support legs 14 at the bottom end of the four corners, and the length of the bottom plate 15 is smaller than the top wall of the extruding box 12, which provides stability to the structure and may facilitate the use or observation of the space below.

[0035] The extrusion box 12 integrates feeding, extrusion and discharging functions. The first feeding port 13 is accurately positioned corresponding to the incoming material from the previous process, realizing seamless connection of the process. The core extrusion assembly adopts a double-belt extrusion design. The independent driving and supporting design of the upper extrusion part and the lower extrusion part makes the operation of the upper extrusion belt 19 and the lower extrusion belt 23 extremely stable, avoids single-point stress deformation, and ensures the uniform consistency of the extrusion gap, which is the key to realizing uniform and efficient extrusion separation. The upper fixed plate 20 and the lower fixed plate 24 not only provide support, but also effectively transfer the extrusion pressure to the material through the design of sliding contact with the extrusion belt, while reducing excessive deformation and deviation of the extrusion belt due to stress, prolonging the service life of the equipment. The feeding area is arranged above the non-overlapping part of the lower extrusion belt 23, so that the material can fall smoothly on the lower extrusion belt 23 and be smoothly introduced into the extrusion area, preventing blockage or impact caused by direct falling into the extrusion gap. The discharging area is arranged below the non-overlapping part of the upper extrusion belt 19, and the material falls naturally by gravity, with simple and reliable structure. During the extrusion process, the double-layer belts moving towards each other form a continuous "roller pressing" effect. Compared with traditional single impact or rolling, this design can perform multi-round, flexible and gradual extrusion on the oil tea fruit, which can fully crush the fruit pulp and reduce the risk of damage to the tea seeds under the instantaneous impact, improving the integrity of the tea seeds. The mixture after separation is discharged directly to the second transfer mechanism, ensuring continuous transmission of the material flow. The extrusion mechanism realizes efficient, gentle, continuous and controllable mechanical extrusion and separation of the dried oil tea fruit through the precise cooperation of the extrusion box 12, the upper extrusion part and the lower extrusion part, and the stable support of the bottom plate 15 and the support legs 14, providing ideal material for the subsequent pulp-seed screening and separation process, and is one of the core links for improving the separation efficiency and quality of the entire cleaning device.

[0036] Further, the pulp-seed separation mechanism includes a screening box 33. A second feeding port 34 is formed in one end of the top wall of the screening box 33, and the second feeding port 34 is located below the high end of the second transfer mechanism. An out-pulp port 36 is formed in the middle of the side wall of the screening box 33 away from the second feeding port 34. A residue discharge port 37 is formed in the bottom of the side wall of the screening box 33 away from the second feeding port 34. An out-seed port 35 is formed in the side wall of the screening box 33 adjacent to the out-pulp port 36. The out-seed port 35 is located between the out-pulp port 36 and the residue discharge port 37. A pulp-seed screening part and a seed residue screening part are arranged in the screening box 33. The pulp-seed screening part corresponds to the out-pulp port 36, and the seed residue screening part corresponds to the out-seed port 35.

[0037] Furthermore, the cattail seed screening section includes a cattail seed screen plate 38, which is inclined. The high end of the cattail seed screen plate 38 is located below the second feed inlet 34, and the low end of the cattail seed screen plate 38 extends to the outside of the screening box 33 through the cattail seed outlet 36. A slide rod 41 and the output end of the first reciprocating motor 40 are fixedly connected to both ends of one side wall of the cattail seed screen plate 38, respectively. A slide rod 41 is fixedly connected to both ends of the other opposite side wall of the cattail seed screen plate 38, respectively. The first reciprocating motor 40 is fixedly connected to the inner side wall of the screening box 33, and the slide rod 41 is slidably connected in the sleeve 42 fixed to the inner side wall of the screening box 33.

[0038] Furthermore, the seed residue screening section includes a seed residue screen plate 39, which is inclined. The high end of the seed residue screen plate 39 is located inside the screening box 33, and the low end of the seed residue screen plate 39 extends to the outside of the screening box 33 through the seed outlet 35. The two opposite side walls of the high end of the seed residue screen plate 39 are rotatably connected to the inner side wall of the screening box 33 through a rotating shaft 44. The bottom wall of the low end of the seed residue screen plate 39 is rotatably connected to the output shaft of a second reciprocating motor 43, and the second reciprocating motor 43 is fixedly connected to the inner bottom wall of the screening box 33.

[0039] The material processed by the extrusion mechanism and conveyed by the second transfer mechanism falls from the high end of the second transfer mechanism and enters the separation mechanism through the second feed inlet 34 on the top wall of the screening box 33. The material first falls onto the core component of the inclined cattail seed screening section—the cattail seed screen plate 38, with its high end directly below the second feed inlet 34 to receive the incoming material. At this time, the cattail seed screening section starts working: the output end of the first reciprocating motor 40, fixed to the inner wall of the screening box 33, is connected to one side wall of the cattail seed screen plate 38, driving the screen plate to reciprocate; at the same time, the sliding rods 41, fixedly connected to both ends of the opposite side wall of the screen plate and the other end of the same side, slide within the sleeves 42 fixed to the inner wall of the box, together forming a stable sliding guide and support structure. Thus, the entire cattail seed screen plate 38, driven by the first reciprocating motor 40, vibrates regularly along its inclined plane. Under the action of vibration, the material spreads on the screen surface of the cattail seed screen plate 38 and moves towards the lower end along the inclined plane. During this process, smaller tea seeds and some fine impurities fall through the sieve holes of the cattail seed sieve plate 38, while larger cattail fragments cannot pass through the sieve holes. Under the action of sieve surface vibration and their own gravity, they continue to move towards the lower end of the sieve plate and are finally discharged from the box through the cattail outlet 36 opened on the side wall of the screening box 33, which corresponds to the lower end of the cattail seed sieve plate 38, thus completing the first separation of "cattail" from "seeds and residue".

[0040] The tea seed mixed with fine impurities that pass through the sieve holes of the cottonseed sieve plate 38 falls onto the core component of the seed residue screening part, the seed residue sieve plate 39, located below it. The seed residue sieve plate 39 is also arranged obliquely, with its high end located inside the screening box 33 to receive the falling material, and its low end extending out of the box through the seed outlet 35 opened in the side wall of the screening box 33. The working mode of the seed residue screening part is different from that of the cottonseed screening part: the two opposite side walls of the high end of the seed residue sieve plate 39 are rotationally connected to the inner side walls of the screening box 33 through the rotating shaft 44, so that the sieve plate can swing around this shaft; at the same time, the bottom wall of the low end of the sieve plate is rotationally connected to the output shaft of the second reciprocating motor 43, while the second reciprocating motor 43 itself is fixed to the inner bottom wall of the screening box 33. When the second reciprocating motor 43 works, the reciprocating motion of its output shaft will drive the low end of the seed residue sieve plate 39 to make reciprocating motion, and since the high end is hinged to be constrained by the rotating shaft 44, while the hinge point is left with a certain movement space, the entire sieve plate is essentially reciprocatingly swung around the high-end rotating shaft as the fulcrum. The material falling on the seed residue sieve plate 39 is uniformly distributed on the sieve surface and moves along the inclined surface to the low end under the action of shaking. The size of the sieve holes of the seed residue sieve plate 39 is smaller than the particle size of the tea seed but larger than the particle size of most fine impurities, so during the shaking and screening process, the qualified tea seeds cannot pass through the sieve holes and gradually move to the low end under the guidance of the sieve surface, and finally are collected through the seed outlet 35, realizing the discharge of clean tea seeds; while the finer impurities pass through the sieve holes of the seed residue sieve plate 39 and fall into the bottom of the screening box 33, and are finally collected and discharged through the residue discharge port 37 opened in the bottom of the box body, thereby completing the final fine separation of "seed" and "residue". At this point, the mixed material is separated into fruit cotton, clean tea seeds and fine impurities after being processed by the mechanism.

[0041] The screening box 33 integrates feeding, two-stage screening and three material discharging functions, and has compact structure. The positions of the second feeding port 34, the pulp discharging port 36, the seed discharging port 35 and the residue discharging port 37 are accurately designed to correspond to the material flow and the separation target, and realize the orderly shunting in space. The core pulp seed screening part adopts reciprocating linear vibration design, is driven by the first reciprocating motor 40, and is accurately guided by the sliding of the slide rod 41 in the sleeve 42, so as to ensure the stability of the movement of the pulp seed screen plate 38 and the controllability of the trajectory. This vibration mode can effectively throw, loosen and forward the material, and is especially suitable for the rapid separation of "pulp" and "seed and residue" with large size difference, has high separation efficiency, and is not easy to block the screen hole. The seed residue screening part adopts a shaking design of swinging around the rotating shaft 44, and is driven by the second reciprocating motor 43 to realize the swinging of the low end of the screen plate. This swinging shaking can produce stronger vertical acceleration, has better cleaning effect on the fine dust and small residue attached to the surface of the tea seed, and is more conducive to the small impurities passing through the screen hole, and is especially suitable for the fine screening of "seed" and "residue" with small size difference and high separation difficulty, and can significantly improve the cleanliness of the tea seed. The two-stage screening adopts different motion modes, and is optimized according to the characteristics of the materials in different separation stages, so as to realize the perfect combination of "coarse screening" and "fine screening". The whole separation process is carried out in the closed screening box 33, which effectively prevents dust from escaping. In summary, the pulp seed separation mechanism realizes the continuous and efficient separation and cleaning of the mixture after extrusion into fruit pulp, clean tea seed and impurities in one device through the cooperation of the screening box 33, the pulp seed screening part, the seed residue screening part and the in-out ports, and two kinds of optimized screening movements, and is the key functional module for ensuring the quality and purity of the tea seed output by the whole cleaning device.

[0042] Further, the first transfer mechanism includes two first support rods 4, which are vertically and spaced apart, wherein one side wall top end of one of the first support rods 4 is fixedly connected with a first motor 5, one end of an output shaft of the first motor 5 is coaxially fixedly connected with a first driving roller 6, the other end of the first driving roller 6 is rotatably connected with the top of the other first support rod 4, and the two first support rods 4 are respectively provided with a second support rod 7 on one side close to the drying and popping box 1, the height of the second support rod 7 is less than that of the first support rod 4, and the top portions of the two second support rods 7 are jointly rotatably connected with a first driven roller 8, the first driven roller 8 and the outer side of the first driving roller 6 are jointly and drivingly provided with a first conveying belt 9, and the outer surface of the first conveying belt 9 is fixedly connected with a plurality of first blocking strips 10 which are equally spaced, and the two ends of the plurality of first blocking strips 10 are respectively fixedly connected with first blocking rings 11.

[0043] Two taller first support rods 4 are located at the upper end, while two shorter second support rods 7, closer to the drying and popping box 1, are located at the lower end. During operation, the first motor 5 starts, driving the first active roller 6, coaxially fixed to its output shaft, to rotate. This, in turn, drives the first conveyor belt 9, which is positioned around the outside of the first active roller 6 and the first driven roller 8. The camellia fruits falling from the discharge port of the drying and popping box 1 land on the lower end of the first conveyor belt 9. Several first baffles 10 fixedly connected to the surface of the conveyor belt, along with their respective first baffle rings 11, form a regular grid unit, effectively preventing the material from sliding down during the inclined conveying process. Driven by the first conveyor belt 9, the material is steadily lifted upwards until it falls from the upper end and enters the subsequent extrusion mechanism.

[0044] The tilt angle is naturally formed by the height difference between the first support rod 4 and the second support rod 7, enabling the material to be lifted and transferred from the lower drying outlet to the higher extrusion inlet. The first motor 5 provides stable power through the first driving roller 6 and the first driven roller 8. The key design lies in the first baffle 10 with a first baffle ring 11 installed on the first conveyor belt 9. This greatly increases the load-bearing capacity and anti-slip ability of the conveyor belt when it is tilted, ensuring that the camellia fruit can be reliably, continuously, and without backflow, providing a stable material flow for subsequent processes.

[0045] Furthermore, the second transfer mechanism includes two third support rods 25, which are vertically arranged and spaced apart. The third support rods 25 are fixedly connected to the top end of the seed separation mechanism. A fourth motor 26 is fixedly connected to the top of the side wall of one of the third support rods 25. The output shaft of the fourth motor 26 is coaxially fixedly connected to one end of a fourth drive roller 27. The other end of the fourth drive roller 27 is rotatably connected to the top of the other third support rod 25. A fourth support rod 28 is respectively arranged on the side of the two third support rods 25 near the extrusion mechanism. A fourth driven roller 29 is rotatably connected between the tops of the two fourth support rods 28. The fourth driven roller 29 and the fourth drive roller 27 are driven together by a second conveyor belt 30. A number of equally spaced second baffles 31 are fixedly connected to the outer surface of the second conveyor belt 30. A second retaining ring 32 is fixedly connected to both ends of the number of second baffles 31.

[0046] The high end is supported by two third support rods 25 fixed at the top end of the cottonseed separating mechanism, and the low end is supported by two fourth support rods 28 close to one side of the extruding mechanism. After starting, the fourth motor 26 fixed on the third support rod 25 drives the fourth driving roller 27 to rotate, thereby driving the second conveying belt 30 wound outside the fourth driving roller 27 and the fourth driven roller 29 to rotate. The mixture falling from the discharge port of the extruding mechanism falls on the second conveying belt 30 at the low end, and the surface fixed with a plurality of second blocking strips 31 and the second blocking rings 32 at both ends form a blocking. Under the driving of the second conveying belt 30, the material is stably lifted upward, and finally falls from the high end, enters the subsequent screening process through the second feeding port of the cottonseed separating mechanism.

[0047] By being directly fixed to the cottonseed separating mechanism through the third support rod 25, the structural integration with the downstream equipment is realized, and the layout is compact. The fourth support rod 28 is located close to one side of the extruding mechanism, and naturally forms a lifting inclination angle. The fourth motor 26 provides reliable power through the fourth driving roller 27 and the fourth driven roller 29. The second blocking strips 31 and the second blocking rings 32 arranged on the second conveying belt 30 also effectively prevent the material that becomes small and loose after extrusion from sliding or spilling out during the inclined conveying process, ensuring the continuous, stable and leakage-free transfer of the material from the extruding process to the separating process, and ensuring the smooth connection of the entire production line process.
