Description

Technical Field

[0001] The invention belongs to the technical field of processing and feeding devices, in particular to a stevia processing and feeding device. Background Art

[0002] Stevia is a perennial herb belonging to the genus Stevia in the Asteraceae family. It is noticed and used because its leaves contain high-sweetness, low-calorie natural sweeteners. It is widely used in food (such as beverages, candies, cakes), health products, medicine (such as sweeteners for diabetic patients) and other fields, replacing part of sucrose to meet the "low sugar" and "healthy" consumer demand.

[0003] In the current existing technology, when processing stevia, the raw stevia leaves go through soaking, extraction, filtration and other steps to separate the sugar. The processed liquid will contain impurities such as broken leaves, stem debris, and residual sugar. These impurities will mix together to form a large amount of waste liquid. The waste liquid is generally discharged directly into the waste liquid pool for centralized collection and then further processing.

[0004] When the waste liquid in the waste liquid pool needs to be transported to the next processing link for solid-liquid separation and other treatment steps, an auger is generally installed in the waste liquid pool, and the waste liquid in the pool is discharged by relying on the blades on the auger. However, since the waste liquid may contain solid impurities such as broken leaves and stem fragments, if the auger is directly used to transport it, fibrous impurities such as stems may be entangled on the auger blades or conveying rods, affecting the normal transportation of the auger.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 5 As shown, a stevia processing feeding device according to an embodiment of the present invention includes a waste liquid bin 1, wherein a conveying mechanism 3 for conveying waste liquid generated during stevia processing is disposed inside the waste liquid bin 1, and an auxiliary mechanism 5 for crushing impurities in the stevia waste liquid is disposed above the conveying mechanism 3;

[0036] The conveying mechanism 3 includes a rotatable auger 302, and two guide plates 307 are provided above the auger 302. A driving gear 304 is fixedly connected to one end of the auger 302, and a driven gear 306 is transmission-connected to the upper portion of the driving gear 304.

[0037] The auxiliary mechanism 5 includes a crushing rod 501, a plurality of crushing leaves 504 are fixedly connected to the surface of the crushing rod 501, a movable sleeve 503 is slidably engaged on the surface of the crushing rod 501, and a plurality of shifting rods 502 are fixedly connected to the surface of the movable sleeve 503. The shifting rods 502 can push the two guide plates 307 to swing back and forth.

[0038] The present invention takes into account that after stevia is processed such as purification, a large amount of waste liquid and waste residue will be generated, and the waste residue liquid is usually discharged into the interior of the waste liquid bin 1, and then the waste liquid residue is transported by the rotation of the auger 302 to perform solid-liquid separation and other steps. However, since there may be solid impurities such as stems and other fibers in the waste liquid residue, if the auger 302 is used directly to transport it, the fiber impurities are likely to adhere to the surface of the auger 302, causing friction between the auger 302 and the waste liquid bin 1, causing wear of the auger 302, which will not only reduce the transportation effect of the waste liquid residue, but also may cause damage to the equipment.

[0039] The auger 302 is first started to rotate, and the rotation of the auger 302 drives the driving gear 304 to rotate, and the driving gear 304 drives the driven gear 306 to rotate, and the rotation of the driven gear 306 drives the crushing rod 501 to rotate, and the rotation of the crushing rod 501 drives the multiple crushing leaves 504 to rotate. It should be noted that when the waste liquid slag enters the interior of the waste liquid bin 1, it will first fall on the surface of the guide plate 307. After the reciprocating swing of the guide plate 307 to guide the flow, the waste residue liquid will be in a dispersed state and directed to the position of the crushing leaves 504. At this time, the rotation of the crushing leaves 504 can cut the solid impurities in the waste residue liquid in advance, avoid the solid impurities in the waste residue liquid flowing into the auger 302, and avoid the fiber solid impurities from being entangled on the surface of the auger 302, which can improve the conveying effect of the auger 302.

[0040] 2, and the lower surface of the guide plate 307 is kept in contact with the lever 502, so that the guide plate 307 can swing back and forth around the pin shaft.

[0041] It should be noted again that, since the surface of the guide plate 307 is provided with a discharge groove, and its upper surface is arranged in an arc shape, and the surface arc height of the guide plate 307 near the crushing rod 501 is smaller than the surface arc height near the inner wall of the waste liquid bin 1, when the waste liquid falls on the surface of the guide plate 307, the guide plate 307 can better guide the waste liquid to the position of the crushing leaf 504 for early crushing. It should be explained that when part of the waste liquid falls on the higher arc surface of the guide plate 307, it can rely on the impact of the falling waste liquid to The guide plate 307 can guide it better, speeding up the flow rate of the waste liquid toward the crushing leaf 504. After the waste liquid falls on the shorter arc surface of the guide plate 307, the flow rate of the waste liquid can be slowed down to a certain extent, preventing a large amount of fiber solid impurities in the waste liquid from concentrating on the crushing leaf 504. This can not only prevent the waste liquid from accumulating on the surface of the guide plate 307, but also prevent a large amount of impurities from flowing to the crushing leaf 504 to cause blockage, thereby affecting the effect of the crushing leaf 504 on crushing the fiber solid impurities in the waste liquid.

[0042] like Figures 2 to 3 As shown, the conveying mechanism 3 also includes a motor 301 fixedly connected to one side of the waste liquid bin 1, and the auger 302 is installed at the output end of the motor 301. An idler gear 305 is meshedly connected above the driving gear 304, and the idler gear 305 is meshedly connected to the driven gear 306. The size of the driving gear 304 is smaller than that of the driven gear 306. The guide plate 307 is arranged inside the waste liquid bin 1 through a pin shaft, and a return spring is provided at the angle between the guide plate 307 and the waste liquid bin 1. An inclined plate 303 is provided inside the waste liquid bin 1, and the two sides of the inclined plate 303 are inclined. An arc groove is opened inside the inclined plate 303, and the auger 302 rotates in the arc groove opened in the inclined plate 303.

[0043] During operation, when it is necessary to transport the waste liquid produced by stevia, the motor 301 is first started to drive the auger 302 to rotate in the arc groove opened by the inclined plate 303, and the diameter of the auger 302 is similar to the diameter of the arc groove opened by the inclined plate 303. At this time, the auger 302 can fully contact the falling waste liquid during rotation, so that the auger 302 can effectively transport the waste liquid. It should be noted that since the two sides of the inclined plate 303 are inclined and fixed to the waste liquid bin 1, the crushed waste liquid will be guided to the inside of the arc groove, so that the auger 302 can better transport the waste liquid.

[0044] The auger 302 drives the driving gear 304 to rotate, and the driving gear 304 meshes and drives the idler gear 305 to rotate. The idler gear 305 rotates and meshes and drives the driven gear 306 to rotate. The driving gear 304 and the idler gear 305 have the same size, while the driving gear 304 is smaller than the driven gear 306. At this time, the driving gear 304 can drive the driven gear 306 to rotate in the same direction as it, while the speed of the driven gear 306 will be lower than the rotation of the driving gear 304. It should be noted that since the driven gear 306 can cause multiple groups of shift levers 502 to rotate, the rotation of the shift lever 502 will intermittently push the two guide plates 307 to swing back and forth around the pin shaft inside the waste liquid bin 1, which can prevent the driven gear 306 from rotating too high and affecting the normal swing of the guide plates 307, causing the guide plates 307 to be unable to evenly guide the waste liquid, thereby further improving the use effect of the guide plates 307.

[0045] It should be noted again that, since a reset spring is provided at the angle between the guide plate 307 and the waste liquid bin 1, when the guide plate 307 is swinging back and forth, it can not only rely on itself and the downward gravity of the waste liquid to always be in contact with the multiple levers 502, but also under the action of the reset spring, it can further make the guide plate 307 contact with the lever 502 to avoid separation, which causes the lever 502 to be unable to drive the guide plate 307 to swing back and forth, and can improve the utilization rate of the guide plate 307, thereby improving the effect of uniformly dispersing and guiding the waste liquid, so that the crushing leaves 504 can crush the evenly falling waste liquid to avoid blockage and the like.

[0046] like Figures 4 to 7 As shown, the auxiliary mechanism 5 also includes a connecting tube 505 fixedly connected to one side of the movable sleeve 503, and the connecting tube 505 and the breaking rod 501 are also slidably engaged. A plurality of sliding columns 506 are fixedly provided on one side of the connecting tube 505, and one end of the sliding column 506 is in sliding contact with a protrusion 507, and the protrusion 507 is fixedly connected to the inner wall of the waste liquid bin 1, and a spring tube is provided on the end of the movable sleeve 503 away from the protrusion 507.

[0047] When the driven gear 306 drives the breaker bar 501 to rotate, the rotation of the breaker bar 501 can drive the movable sleeve 503 and the connecting cylinder 505 to rotate synchronously. The rotation of the connecting cylinder 505 can drive multiple sliding posts 506 to rotate. During the rotation process, one end of the sliding post 506 will continuously slide in contact with the surface of the protrusion 507. Since the protrusion 507 is fixed to the inner wall of the waste liquid bin 1 and does not move, the sliding post 506 will be pushed by the protrusion 507 to drive the connecting cylinder 505 and the movable sleeve 503 to slide on the surface of the breaker bar 501. The sliding of the movable sleeve 503 can drive multiple levers 502 to slide, so that the lever 502 can swing a short distance. It should be noted that the swinging of the lever 502 will continuously change the contact position with the guide plate 307, so that the guide plate 307 can be better pushed by the rotation of the lever 502, so that the guide plate 307 can swing better.

[0048] The auger 302 is rotated to move the auger 302 to the left and right sides of the auger 302, and the auger 302 is rotated to move the auger 302 to the right and left sides of the auger 302. The auger 302 is rotated to move the auger 302 to the left and right sides of the auger 302, and the auger 302 is rotated to move the auger 302 to the right and left sides of the auger 302.

[0049] It needs to be explained again that the short-distance shaking of the movable sleeve 503 can also prevent some small solid impurities from adhering to the surface of the crushing rod 501 and accumulating on the surface of the crushing rod 501 for a long time, affecting the crushing effect of the crushing leaves 504 on the fiber-like solid impurities, and can effectively improve the crushing effect of the crushing leaves 504 on the fiber-like solid impurities. It can also prevent the movable sleeve 503 from getting stuck when shaking on the surface of the lever 502, and can improve the sliding smoothness of the movable sleeve 503. It needs to be explained that by arranging a spring cylinder at the end of the movable sleeve 503 away from the protrusion 507, the sliding column 506 can be pushed and can be quickly reset by relying on the reverse force of the spring cylinder, so that multiple levers 502 can move back and forth quickly.

[0050] like Figures 8 to 11As shown, a gain mechanism 6 for treating the inner wall of the waste liquid bin 1 and the stevia waste liquid after auxiliary crushing is configured below the guide plate 307. The gain mechanism 6 includes a connecting rod 601 rotatably connected to the lower surface of the guide plate 307. The other end of the connecting rod 601 is rotatably connected to a lower scraper 602 through a pin shaft. The upper part of the lower scraper 602 is connected to an upper scraper 603 through a fixed rod. The surfaces of the lower scraper 602 and the upper scraper 603 are both arranged in an arc shape, and the arc diameter of the lower scraper 602 is smaller than the arc diameter of the upper scraper 603. The connecting rod 601 is telescopic.

[0051] The present invention also takes into account that when the stevia waste liquid is rotated, crushed and dispersed by the auxiliary mechanism 5, the volume of solid impurities in the crushed waste liquid will become smaller. At this time, since some sugar and used chemical components may still remain in the waste liquid, when the waste liquid with a small volume after being crushed falls on the inclined surfaces on both sides of the inclined plate 303, it may adhere to the inner wall of the waste liquid bin 1 and the inclined surface of the inclined plate 303 due to the action of the residual sugar and chemical agents, and cannot continue to fall into the arc groove opened by the inclined plate 303, and will not be transported out by the auger 302, which will reduce the effect of the auger 302 on the waste liquid transportation. In addition, after the small solid impurities accumulate on the inclined surface of the inclined plate 303 or the inner wall of the waste liquid bin 1 for a long time, they will affect the normal flow of the subsequent waste liquid to the position of the auger 302, resulting in a reduction in the flow effect of the waste liquid and the inability of the auger 302 to effectively transport it.

[0052] Therefore, a connecting rod 601 is provided below the guide plate 307 through a pin shaft, and the other end of the connecting rod 601 is connected to the lower scraper 602 through a pin shaft, and the lower scraper 602 is fixedly connected to the upper scraper 603 through a fixing rod. When the guide plate 307 continuously swings back and forth around the pin shaft, it can drive the connecting rod 601 to move, so that the connecting rod 601 transmits force to the lower scraper 602 and the upper scraper 603, thereby driving the lower scraper 602 and the upper scraper 603 to swing in an arc, which can scrape off small solid impurities adhering to the inner wall of the waste liquid bin 1. The scraped impurities are wiped so that they can flow with the liquid to the position of the auger 302 again, which is convenient for the auger 302 to transport them. It should be noted that by making the arc diameter of the lower scraper 602 smaller than the arc diameter of the upper scraper 603, when the lower scraper 602 and the upper scraper 603 slide on the inner wall of the waste liquid bin 1, the upper scraper 603 can better drive the liquid to fluctuate, so that the liquid and the small impurities scraped off are remixed, so that the liquid drives the small solid impurities to flow to the position of the auger 302, which is convenient for the auger 302 to transport them in a centralized manner.

[0053] It should be noted that since the lower scraper 602 is close to the position of the auger 302, when the lower scraper 602 scrapes small and easily adhered impurities, in order to avoid the lower scraper 602 causing large fluctuations in the liquid, the liquid can flow more smoothly to the position of the auger 302, avoiding chaos in the liquid and affecting the effect of the auger 302 on conveying small liquids, and the connecting rod 601 is set to be telescopic, which can avoid the connecting rod 601 being pushed by the guide plate 307 when the connecting rod 601 is swung. At this time, the connecting rod 601 cannot push the lower scraper 602 and the upper scraper 603 to slide back and forth for wiping, which can improve the sliding and wiping effect of the two, and the surfaces of the two are set in an arc shape, which can better make it contact with the inner wall of the waste liquid bin 1, thereby improving the scraping effect of the inner wall of the waste liquid bin 1.

[0054] like Figures 8 and 9 As shown, a swingable swing plate 604 is provided at the position of the fixed rod between the lower scraper 602 and the upper scraper 603, and a first push plate 605 is provided between the two connecting rods 601. The lower surface of the first push plate 605 is in sliding contact with the inclined surface of the inclined plate 303, and an oblique square hole is opened at a position of the first push plate 605 away from the inclined surface of the inclined plate 303.

[0055] When the connecting rod 601 is in operation, it is squeezed by the guide plate 307 and displaced. At this time, the connecting rod 601 will perform telescopic movement. Since a first push plate 605 is provided between the two connecting rods 601, the first push plate 605 can limit the telescopic distance of the connecting rod 601, so as to avoid the situation that the connecting rod 601 cannot be reset due to the telescopic distance being too long. It should be noted that when the connecting rod 601 is telescopic, it will drive the first push plate 605 to slide in contact with the inclined surface of the inclined plate 303, so that the first push plate 605 can effectively contact the inclined surface of the inclined plate 303. Moreover, since the two ends of the first push plate 605 are rotatably connected to the connecting rod 601, when the first push plate 605 moves to a position away from the auger 302, the first push plate 605 will continuously become an inclined state, thereby being able to push the liquid to move to the position of the upward scraper 603, so that the small solid impurities after scraping can be fully mixed with the liquid, which is convenient for flowing to the position of the auger 302 for transportation.

[0056] It should be noted that, by providing an oblique square hole above the first push plate 605, when the first push plate 605 moves back and forth, part of the liquid can pass through the square hole and quickly flow to the position of the upper scraper 603, which can further improve the full mixing of small solid impurities and liquid, thereby facilitating the flow of small and highly adhesive solid impurities to the position of the auger 302. It should be explained that, by providing a plurality of rectangular through grooves below the first push plate 605, not only can the surface of the inclined plate 303 be partially scraped, but also small solid impurities will not be hindered from mixing with the liquid and flowing to the position of the auger 302.

[0057] like Figures 10 and 11 As shown, the gain mechanism 6 also includes a push plate 606, the surface of which is in sliding contact with two slide bars 607, the surface of which is in sliding contact with the inclined surface of the inclined plate 303, and a second push plate 608 is fixedly connected between the two slide bars 607, and a plurality of rectangular grooves are provided inside the second push plate 608, and the rectangular grooves provided inside the second push plate 608 are staggered with the rectangular grooves provided inside the first push plate 605.

[0058] During operation, when the driving gear 304 rotates, it will mesh with the transmission to drive the idler wheel 305 to rotate. The rotation of the idler wheel 305 will drive the push plate 606 to rotate. The rotation of the push plate 606 can push the slide bar 607 to slide on the inclined surface of the inclined plate 303. At this time, the sliding reciprocating motion of the slide bar 607 can drive the second push plate 608 to slide back and forth on the inclined surfaces on both sides of the inclined plate 303. Moreover, since the rectangular grooves provided inside the second push plate 608 are staggered with the rectangular grooves provided on the first push plate 605, and the sliding speed of the second push plate 608 is greater than the sliding speed of the first push plate 605, when small solid impurities are mixed with the liquid, the liquid is pushed by the first push plate 605. After the plate 605 is pushed to the position of the second push plate 608, the liquid flows to the position of the second push plate 608 through the rectangular groove. At this time, the rectangular groove of the second push plate 608 is staggered with the rectangular groove of the first push plate 605, which can prevent solid impurities from re-adhering to the space between the first push plate 605 and the second push plate 608 during the flow of the liquid. At this time, the rapid reciprocating motion of the second push plate 608 can not only further improve the mixing effect of the liquid and the small solid impurities, but also can quickly push the mixed liquid to the position of the auger 302, so that the auger 302 can quickly transport the impurities, thereby improving the effect of transporting the waste liquid;

[0059] It should be noted that, since the slide bar 607 is in sliding contact with the inclined surface of the inclined plate 303, and the slide bar 607 is located on one side of the inner wall of the waste liquid bin 1, by setting a reset spring at the position of the slide bar 607 and the inner wall of the waste liquid bin 1, the slide bar 607 can be quickly reset after being quickly pushed by the push plate 606, so that the second push plate 608 can swing back and forth quickly, which can not only prevent impurities from re-adhering to the surface of the inclined plate 303, that is, the position between the first push plate 605 and the second push plate 608, but also can quickly transport the mixed liquid to the position of the auger 302, so that the auger 302 can quickly transport it.

[0060] like Figures 1 to 2 As shown, several groups of liquid inlets 4 are provided above the waste liquid bin 1, and the liquid inlets 4 are located directly above the two guide plates 307. The discharge troughs provided on the surface of the guide plates 307 are arranged in an arc shape, and the two guide plates 307 are arranged at an angle. A sprinkler 2 is provided on one side of the waste liquid bin 1.

[0061] During operation, after the waste liquid enters the interior of the waste liquid bin 1, it will be injected into the interior of the waste liquid bin 1 through multiple liquid inlets 4. Since the liquid inlet 4 is located directly above the guide plate 307, that is, located on the curved surface with a high height of the guide plate 307, and part of the waste liquid will fall into the interior of the discharge trough, when the waste liquid falls, it will first fall into the interior of the discharge trough and be collected by the discharge trough, so that the waste liquid will not be over-dispersed. When the subsequent lever 502 pushes the two guide plates 307 to swing back and forth continuously, the waste liquid that is first concentrated can be quickly and evenly dispersed, so that it can better flow to the position of the crushing leaf 504 for rotational crushing processing, and when the auger 302 transports the waste liquid out, the sprinkler 2 is started to flush the surface of the auger 302 inside the delivery pipe, so that the auger 302 can better transport the waste liquid generated by stevia processing.

[0062] like Figures 5 to 7 As shown, the movable sleeve 503 slidingly engaged on the surface of the breaker rod 501 is connected by a fixed column, and the lever 502 fixedly set on the surface of the movable sleeve 503 is distributed at an angle of 120°. The contact position between the lever 502 and the guide plate 307 is made of highly wear-resistant material.

[0063] During operation, multiple movable sleeves 503 are fixed together by fixed columns, so that the movable sleeves 503 can move synchronously when sliding on the surface of the crushing rod 501, and can better drive the multiple levers 502 to shake, so that the crushed solid impurities can be further broken up and separated, and the multiple levers 502 are distributed at an angle of 120°, and the same straight line is formed between the multiple levers 502, that is, the multiple levers 502 are axially distributed on the surface of the movable sleeve 503, presenting a straight line. At this time, even if the multiple levers 502 can shake, it will not affect the contact effect with the guide plate 307, so as to better drive the guide plate 307 to swing around the pin shaft, thereby avoiding affecting the normal operation of the guide plate 307.

[0064] like Figures 8 and 9 As shown, one side of the lower scraper 602 and the upper scraper 603 is in close contact with the inner wall of the waste liquid bin 1, the upper surface and the lower surface of the swing plate 604 are both arc-shaped, and the initial state of the swing plate 604 is in a tilted downward state.

[0065] During operation, by bringing one side of the lower scraper 602 and the upper scraper 603 into close contact with the inner wall of the waste liquid bin 1, when the lower scraper 602 and the upper scraper 603 slide and scrape on the inner wall of the waste liquid bin 1, the inner wall of the waste liquid bin 1 can be better cleaned, and the cleanliness of the inner wall of the waste liquid bin 1 can be effectively improved, thereby avoiding affecting the normal flow of subsequent waste liquid, and enabling the auger 302 to effectively transport the waste liquid, thereby avoiding incomplete transportation of the waste liquid. It should be noted that, by setting the upper and lower surfaces of the swing plate 604 in an arc shape, and the initial state of the swing plate 604 is in an inclined downward state, when the lower scraper 602 and the upper scraper 603 move upward, the volume of impurities scraped off at this time may be removed from the swing plate 6 The lower arc surface of 04 guides the surface of the lower scraper 602, which can enable the swing plate 604 to reduce the fluctuation of the liquid, avoiding large fluctuations in the liquid flowing through the surface of the lower scraper 602, causing the scraped impurities to adhere to the surface of the waste liquid bin 1 again, and when the swing plate 604 follows the lower scraper 602 and the upper scraper 603 to move downward, the lower arc surface of the swing plate 604 will be flipped by the thrust of the liquid, and part of the mixed liquid will flow upward through its upper arc surface, further away from the position of the auger 302, which can fully reduce the liquid fluctuation near the auger 302, so that the auger 302 can not only effectively transport small impurities, but also avoid the secondary attachment of small impurities, which can improve the scraping and cleaning effect.

[0066] like Figures 5 to 7 As shown, multiple sliding columns 506 on one side of the connecting tube 505 are evenly distributed at an angle of 120 degrees, and one end of the sliding column 506 is set between two protrusions 507, and multiple crushing leaves 504 on the surface of the crushing rod 501 are set at an angle.

[0067] During operation, by arranging the slide column 506 at an angle of 120 degrees, when one end of the slide column 506 contacts the arc surface of the protrusion 507, they can contact and slide at the same time, so that the slide column 506 can slide better, avoiding the sliding fluctuation of the connecting tube 505, affecting the effect of pushing the guide plate 307 to swing around the pin shaft during the shaking and rotation of the lever 502, and by arranging multiple crushing leaves 504 at an angle, the rotation of the crushing leaves 504 can not only rotationally crush the fibrous solid impurities, but also can to a certain extent break up the crushed impurities, thereby further improving the effect of crushing the fibrous solid impurities, and because the movable sleeve 503 slides on the surface of the crushing rod 501, by arranging the crushing leaves 504 in sections, it can avoid the sliding of the movable sleeve 503 interfering with the normal rotation and crushing of the crushing leaves 504, and the reciprocating sliding movement of the movable sleeve 503 can push the solid impurities in the falling process to the position of the inclined crushing leaves 504, thereby improving the crushing effect of the crushing leaves 504.
