Description

Technical Field

[0001] The invention belongs to the technical field of indigo pigment extraction, in particular to a continuous indigo processing extraction device. Background Art

[0002] The indigo processing continuous extraction equipment is a device used to continuously extract indigo from leaves containing indigo. The equipment consists of a feeding device, a crusher, an extraction device, a filter, an extraction liquid collection tank, a raw material residue extrusion and collection device, a purification device and a drying device.

[0003] The existing indigo processing continuous extraction equipment first washes and dries the harvested leaves containing indigo pigment, then puts the leaves into a crusher through a feeding device, and after crushing, the leaves are transported to an extraction device, where the leaves are fully in contact with the water and solvent added to the extraction device, so that the pigment is released into the solution, thereby forming a mixed liquid containing indigo pigment. The extracted leaves are processed by a raw material residue extrusion and collection device, and the remaining mixed liquid is transported back to the extraction device, while the residue after squeezing is collected. At this time, a water pump is driven to transport the mixed liquid containing indigo pigment to an extract collection tank. In this process, the mixed liquid first passes through a filter screen to form a relatively pure extract after filtration, and then enters the extract collection tank, while the leaf residue remaining on the filter screen is removed by a scraper. Then, the extract in the collection tank is processed by a purification and drying device to finally obtain a relatively pure indigo solid.

[0004] The existing indigo processing continuous extraction equipment still has some problems in actual use. The mixed liquid is transported to the extraction liquid collection tank through a water pump and filtered through a filter to form a relatively pure extract. However, as the mixed liquid is filtered, the filter holes of the filter are prone to accumulate leaf residues. When using a scraper to clean, some leaves will adhere to the filter, causing the filter holes to be blocked. As the use time increases, the filtering effect of the filter gradually decreases. At this time, it is necessary to stop the machine and replace the filter, but the disassembly process is cumbersome and takes a lot of time, resulting in the problem of reduced production efficiency of indigo pigment.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0024] like Figures 1 to 11As shown, an indigo processing continuous extraction device described in an embodiment of the present invention includes a support box 1, a working box 11 is fixedly connected to the top of the support box 1, a liquid injection port 12 is fixedly connected to the top of the working box 11, a shielding cover 13 is fixedly connected to the middle of the top of the working box 11, a rotating shaft 15 is rotatably connected to the bottom of the working box 11, an end of the rotating shaft 15 away from the support box 1 passes through the top of the working box 11 and rotates on the top of the shielding cover 13, a transmission gear ring 16 is fixedly connected to the top of the rotating shaft 15, a half gear 14 is rotatably connected between the top of the shielding cover 13 and the top of the working box 11, and the half gear 14 is meshed with the transmission gear ring 16, a baffle plate 110 is fixedly connected to the inside of the working box 11, the rotating shaft 15 passes through the baffle plate 110, a liquid outlet 17 is opened at the bottom of the working box 11, a collecting tank 19 is fixedly connected to the inside of the support box 1, and an infusion tube 18 is fixedly connected between the top of the collecting tank 19 and the liquid outlet 17; The working box 11 is provided with a cleaning device for cleaning the residue filtered out by the filter screen, and the cleaning device includes a turning component and a flushing component; The flip assembly is disposed in the working box 11, and is used to flip the filter screen over after filtering for a period of time; The flushing assembly is arranged on the working box 11, and is used to flush the filter screen after turning over; The support box 1 is provided with a recovery component, and the recovery component is used to collect the residual extraction liquid in the slag material.

[0025] Specifically, the existing indigo processing continuous extraction equipment still has some problems in actual use. The mixed liquid is transported to the extraction liquid collection tank through a water pump and filtered through a filter to form a relatively pure extract. However, as the mixed liquid is filtered, the filter holes of the filter are prone to accumulate leaf residues. When using a scraper to clean, some leaves will adhere to the filter, causing the filter holes to be blocked. As the use time increases, the filtering effect of the filter gradually decreases. At this time, it is necessary to stop the machine and replace the filter, but the disassembly process is cumbersome and takes a lot of time, resulting in the problem of reduced production efficiency of indigo pigment.

[0026] Therefore, the present invention solves this problem by setting a corresponding structure. First, the harvested leaves containing indigo pigment are washed and dried, and then the leaves are put into the crusher through the feeding device. After crushing, the leaves are transported to the extraction device. The leaves will be fully in contact with the water and solvent added in the extraction device, so that the pigment is released into the solution, thereby forming a mixed liquid containing indigo pigment. The extracted leaves are processed by the raw material residue extrusion and collection device, and the residual mixed liquid is transported back to the extraction device. At the same time, the residue after squeezing is collected. At this time, the driving The water pump delivers the mixed liquid containing indigo pigment to the working box 11 through the liquid injection port 12. In the initial state, the flip assembly is located below the liquid injection port 12 and above the connection between the baffle plate 110 and the working box 11. Through the filtering of the filtering part of the flip assembly, the filtered extract flows into the bottom of the working box 11 through the connection between the baffle plate 110 and the working box 11, and flows into the collecting tank 19 through the liquid outlet 17 and the infusion tube 18. The extract in the collecting tank 19 is processed by the purification and drying device to finally obtain a relatively pure indigo solid. When cleaning the filter part of the flip assembly, in the initial state, the transmission gear collar 16 and the half gear 14 are both provided with four teeth; At this time, the driving half gear 14 rotates one circle, during which the half gear 14 drives the transmission gear ring 16 to rotate. After the rotation, the gear ring 16 is still meshed with the half gear 14. The rotation of the transmission gear ring 16 will drive the rotating shaft 15 to rotate ninety degrees, and the flip assembly on the rotating shaft 15 rotates synchronously, so that the flip assembly after filtering is no longer located under the liquid injection port 12, and the other flip assembly is located under the liquid injection port 12 to continue filtering the mixed liquid. At this time, the flip assembly is driven. When the flip assembly flips 180 degrees, the flushing assembly is driven to flush part of the flip assembly through the flushing assembly until the flip assembly is reset, at which time the flushing assembly stops running; Through the inclined baffle plate 110 and the sealing plug provided at the connection between the baffle plate 110 and the rotating shaft 15, the filtered slag falls onto the baffle plate 110 and slides out of the working box 11 under the lubrication of water and enters the recovery component, and then the residual extract and water in the slag are squeezed out through the recovery component, and the squeezed liquid and the squeezed slag are collected; When the filter part of another flip assembly is to be cleaned, the driving half gear 14 is rotated in the opposite direction by 90 degrees, and then the above operation is performed to complete the cleaning.

[0027] like Figure 4 and Fig.11 As shown, the liquid outlet 17 of this embodiment is opened at the bottom end of the working box 11 with the rotating shaft 15 as the axis, and the blocking plate 110 is inclined.

[0028] Specifically, the liquid outlet 17 is arranged so that the extraction liquid flows into the liquid infusion pipe 18, and the baffle plate 110 is arranged inclined so that the slag and water on the baffle plate 110 slide into the baffle plate 45 through the inclined surface.

[0029] like Figures 3 to 5 and Figures 7 to 9 As shown, the flip assembly described in this embodiment includes a fixed block 21, and the fixed block 21 is fixedly connected to the surface of the rotating shaft 15. The side of the fixed block 21 away from the rotating shaft 15 is fixedly connected to a protective box 22, and a rotating gear 23 is rotatably connected inside the protective box 22. A steering gear 24 rotatably connected inside the protective box 22 is provided on one side of the rotating gear 23. The rotating gear 23 is meshed with the steering gear 24, and one end of the steering gear 24 away from the rotating shaft 15 passes through the protective box 22, and the end of the steering gear 24 away from the rotating shaft 15 is fixedly connected to a fixed block 25, and the end of the fixed block 25 away from the protective box 22 is fixedly connected to a filter plate 26.

[0030] Specifically, when the rotating shaft 15 rotates ninety degrees, the rotating gear 23 is driven to rotate. Since the ratio of the number of teeth of the rotating gear 23 to the number of teeth of the steering gear 24 is set to 1:10, the steering gear 24 is driven to rotate intermittently, and the rotation of the steering gear 24 drives the fixed block 25 and the filter plate 26 to rotate synchronously, so that part of the slag on the filter plate 26 falls under the action of its own gravity until the filter plate 26 is reset, at which time the driving of the rotating gear 23 is stopped.

[0031] like Figure 3 and Figure 4 As shown, the filter plate 26 of this embodiment is located above the connecting portion of the baffle plate 110 and the working box 11 , and the shape of the filter plate 26 matches the shape of the connecting portion of the baffle plate 110 and the working box 11 .

[0032] Specifically, this arrangement allows the mixed liquid to flow into the connection point after being filtered through the filter plate 26 , and then enter the interior of the working box 11 below the baffle plate 110 .

[0033] like Figure 4 As shown, the middle portion of the filter plate 26 in this embodiment is located directly below the liquid injection port 12 .

[0034] Specifically, the middle of the filter plate 26 is located directly below the liquid injection port 12 , so that the mixed liquid passes through the filter plate 26 after passing through the liquid injection port 12 , and the surface of the filter plate 26 is in contact with the mixed liquid more evenly.

[0035] like Figures 1 to 5 and Fig.10As shown, the flushing assembly described in this embodiment includes a water storage tank 31, which is fixedly connected to the top of the support box 1, and a piston box 32 is fixedly connected to one side of the working box 11. A delivery pipe 1 33 is fixedly connected between the water storage tank 31 and the piston box 32, and an electric telescopic rod 34 is fixedly connected to the bottom of the piston box 32, and a displacement plate 35 is fixedly connected to the top of the output end of the electric telescopic rod 34, and the displacement plate 35 slides in the piston box 32. One end of the delivery pipe 1 33 close to the piston box 32 is located at the bottom of the inner cavity on one side of the piston box 32, one side of the top of the piston box 32 is fixedly connected to a delivery pipe 2 36, and the other side is fixedly connected to a delivery pipe 3 37, and the ends of the delivery pipe 2 36 and the delivery pipe 3 37 away from the piston box 32 are respectively fixed to the top of the working box 11, and a nozzle 38 is fixedly connected to the inner top of the working box 11.

[0036] Specifically, a one-way valve is provided at the connection between the water storage tank 31 and the delivery pipe 1 33, and a one-way valve is provided at the connection between the delivery pipe 2 36 and the delivery pipe 3 37 and the displacement plate 35. In the initial state, the displacement plate 35 is located above the displacement plate 35 connected to the delivery pipe 1 33, and the inner cavity of the piston box 32 above the displacement plate 35 is filled with water. When the electric telescopic rod 34 is extended, its output end drives the displacement plate 35 to move synchronously, and then the water in the piston box 32 is transported to the delivery pipe 2 36 and the one-way valve on the delivery pipe 3 37 through the displacement of the displacement plate 35. When the electric telescopic rod 34 is fully retracted, the displacement plate 35 is displaced downward during this process, so that the pressure between the upper part of the displacement plate 35 and the inner cavity of the piston box 32 becomes larger. When the displacement plate 35 passes through the connecting part of the delivery pipe 1 33 on the displacement plate 35, the one-way valve at the connection between the water storage tank 31 and the delivery pipe 1 33 is opened due to the pressure difference, so that the water in the water storage tank 31 enters the inner cavity between the upper part of the displacement plate 35 and the piston box 32.

[0037] The present invention drives the steering gear 24 to rotate by the rotating gear 23, so that the second fixed block 25 drives the filter plate 26 to flip along with the rotation of the steering gear 24, so that the slag filtered on the filter plate 26 falls onto the barrier plate 110 under the action of its own gravity during the flipping process of the filter plate 26, thereby preliminarily cleaning the filter plate 26. After the filter plate 26 flips 180 degrees, the displacement plate 35 is driven to move synchronously by the extension of the electric telescopic rod 34, so that the water in the piston box 32 is transported through the second delivery pipe 36 and the third delivery pipe 37. To the inside of the working box 11, during this process, the water in the delivery pipe 2 36 and the delivery pipe 3 37 is sprayed out through the nozzle 38, so that the filter plate 26 located below it is flushed by the water sprayed by the nozzle 38, and then the residue remaining on the filter plate 26 falls onto the barrier plate 110 under the flushing of the water flow, and the residue remaining on the filter plate 26 is further cleaned, so that the filter holes on the filter plate 26 are no longer blocked, avoiding the problem that part of the blades of the existing filter screen will adhere to the filter screen when using a scraper to clean it, causing the filter holes to be blocked and the filtering effect to be reduced, thereby improving the efficiency of continuous indigo extraction.

[0038] The present invention prevents the filter plate 26 from being blocked and causing a decrease in filtration efficiency by cleaning the filter plate 26, and also prevents the problem of residual residues on the filter plate 26 not being thoroughly cleaned and causing oxidation during a long period of filtration, thereby contaminating the filtered extract, thereby ensuring the purity of the filtered extract.

[0039] like Figure 2 and Fig.10 As shown, in this embodiment, one end of the delivery pipe 1 33 close to the water tank 31 is connected to the bottom of one side of the water tank 31, the delivery pipe 1 33 connects the water tank 31 and the piston box 32, and the delivery pipe 2 36 and the delivery pipe 3 37 connect the piston box 32 and the working box 11.

[0040] Specifically, after the connection, the water in the water storage tank 31 can enter the piston box 32, and at the same time, the water in the piston box 32 can be discharged into the working box 11 through the second delivery pipe 36 and the third delivery pipe 37.

[0041] like Figure 4 As shown, the filter plate 26 in this embodiment is located on the movement trajectory of the water sprayed by the nozzle 38.

[0042] Specifically, the water sprayed from the spray head 38 can flush the filter plate 26 on its movement track. Example

[0043] like Figures 2 to 5 and Fig.11 As shown, compared with Example 1, another implementation of the present invention is: like Figures 2 to 5 and Fig.11 As shown, the recovery assembly of this embodiment includes a support base 41, which is fixedly connected to the top of the support box 1, and the support base 41 is symmetrically arranged, a filter column 42 is fixedly connected between the support bases 41, and a support plate 46 is fixedly connected to one side of the top of the support box 1, a conical groove 43 is opened in the filter column 42, and a conical threaded feeding rod 44 is rotatably connected in the conical groove 43, one end of the conical threaded feeding rod 44 is fixed in the conical groove 43, and the other side is close to the support plate 46. The surface of one side of the filter column 42 is fixed, a blocking plate 1 45 is fixedly connected between the side of the working box 11 close to the support base 41 and the top of the filter column 42, a limiting rod 47 is fixedly connected to the surface of the support plate 46 close to the filter column 42, a one-way motor 49 is fixedly connected to the side of the support plate 46 away from the tapered threaded feeding rod 44, a blocking plate 2 48 is fixedly connected to the end of the limiting rod 47 away from the support plate 46, and the end of the tapered threaded feeding rod 44 close to the support plate 46 passes through the blocking plate 2 48; A collecting groove 410 is provided on the top of the support box 1, a collecting tank 412 is fixedly connected to the middle of the inner cavity of the support box 1, a liquid infusion tube 411 is fixedly connected between the collecting tank 412 and the collecting groove 410, a collecting box 414 is fixedly connected to the side of the support box 1 away from the collecting tank 19, and a feed pipe 413 is fixedly connected between the top of the collecting box 414 and the support box 1.

[0044] Specifically, Fig.11The cleaned slag and water flow into the blocking plate 45 through the blocking plate 110 and are blocked by the inner wall of the blocking plate 45, and then enter the conical groove 43 through the blocking plate 45. Since the conical groove 43 and the filter column 42 are configured to gradually shrink from left to right, and the portion of the output end of the conical threaded feed rod 44 that exceeds the filter column 42 is configured to be a cylinder with the same minimum annular surface as the conical threaded feed rod 44, the one-way motor 49 is started at this time, and the output end of the conical threaded feed rod 44 is driven to rotate by the rotation of the output end of the one-way motor 49, thereby transporting the slag and water between the blocking plate 45 and the conical groove 43 to the conical groove 43. Since the filter column 42 is configured to be a cylinder with filter holes and the portion with filter holes is configured to be above the collecting tank 410, the water in the conical groove 43 is The material leaks out of the filter column 42 when passing over the collecting tank 410 under the transmission of the conical threaded feeding rod 44. At the same time, with the gradual rotation of the conical threaded feeding rod 44, the distance between the material and the conical tank 43 is gradually reduced, so that the residual extract in the material is gradually squeezed out with the continued movement of the conical threaded feeding rod 44, and is discharged through the filter holes on the filter column 42 and drips into the collecting tank 410, and then enters the collecting tank 412 through the collecting tank 410 and the infusion pipe 411. At the same time, the extruded slag is discharged through the slag outlet of the conical tank 43. Since the slag is connected together after extrusion, the slag continues to be discharged at this time until the slag collides with the blocking plate 48, causing the extruded slag to break and fall, and then enter the collecting box 414 through the feeding pipe 413.

[0045] The present invention discharges the residual extract and water in the slag into the collecting tank 410 through the tapered threaded feeding rod 44 and the filter column 42, and collects them into the liquid infusion pipe 411 through the second liquid infusion pipe 411, so that the residual extract in the slag is recovered, further improving the indigo production and reducing the production cost. At the same time, the slag after extrusion is discharged through the slag outlet of the filter column 42 and collides with the baffle plate 48, so that the discharged slag breaks in the process of colliding with the baffle plate 48, and falls into the feed pipe 413 below it under the action of gravity, and then is collected into the collection box 414 through the feed pipe 413. The collected slag can be converted into other products after processing, further reducing the production cost.

[0046] like Fig.11 As shown, the baffle plate 1 45 in this embodiment connects the conical groove 43 and the space of the working box 11 at the top of the baffle plate 110, the collecting groove 410 is located below the baffle plate 1 45 and the filter column 42 near the end of the baffle plate 2 48, and the feed pipe 413 is located below the end of the filter column 42 near the end of the baffle plate 2 48 and the support plate 46 near the end of the baffle plate 2 48.

[0047] Specifically, the blocking plate 145 connects the conical groove 43 and the space of the working box 11 at the top of the baffle plate 110, so that the cleaned residue and water enter the conical groove 43 through the blocking plate 145; the setting of the collecting groove 410 and the conveying pipe 413 enables the discharged extract and water and the extruded residue to be collected by the conveying pipe 2 411 and the collecting box 414 through the collecting groove 410 and the conveying pipe 413 respectively.

[0048] Working principle: First, the harvested leaves containing indigo pigment are washed and dried, and then the leaves are put into a crusher through a feeding device. After crushing, the leaves are transported to an extraction device, where the leaves are fully contacted with water and solvent added in the extraction device, so that the pigment is released into the solution, thereby forming a mixed solution containing indigo pigment. The extracted leaves are processed by a raw material residue extrusion and collection device, and the remaining mixed solution is transported back to the extraction device. At the same time, the residue after squeezing is collected. At this time, a water pump is driven to transport the mixed solution containing indigo pigment into the working box 11 through the injection port 12. In the initial state, the filter plate 26 is located below the injection port 12 and above the connection between the baffle plate 110 and the working box 11. Through the filtration of the filter plate 26, the filtered extract flows into the bottom of the working box 11 through the connection between the baffle plate 110 and the working box 11, and flows into the collecting tank 19 through the liquid outlet 17 and the infusion tube 18. The extract in the collecting tank 19 is processed by a purification and drying device to finally obtain a relatively pure indigo solid. When cleaning the filter plate 26 of the flip assembly, in the initial state, the transmission gear collar 16 and the half gear 14 are both provided with four teeth; At this time, the driving half gear 14 rotates one circle, and in this process, the half gear 14 drives the transmission gear ring 16 to rotate. After the rotation, the gear ring 16 and the half gear 14 are still meshed. The rotation of the transmission gear ring 16 will drive the rotating shaft 15 to rotate ninety degrees, and the flip assembly on the rotating shaft 15 rotates synchronously, so that the flip assembly after filtering is no longer located under the liquid injection port 12, and the other flip assembly is located under the liquid injection port 12 to continue filtering the mixed liquid. At this time, the driving rotating gear 23 rotates. Because the number of teeth of the rotating gear 23 and the number of teeth of the steering gear 24 are set to be 1:10, the steering gear 24 is driven to rotate intermittently, and then the fixed block 25 and the filter plate 26 are driven to rotate synchronously through the rotation of the steering gear 24, so that part of the slag on the filter plate 26 falls under the action of its own gravity; When the filter plate 26 turns over 180 degrees, the electric telescopic rod 34 is started. When the electric telescopic rod 34 is extended, its output end drives the displacement plate 35 to move synchronously, and then the water in the piston box 32 is transported to the inside of the delivery pipe 2 36 and the delivery pipe 3 37 through the one-way valves on the delivery pipe 2 36 and the delivery pipe 3 37 through the displacement of the displacement plate 35, and is discharged into the inside of the working box 11 through the nozzles 38 thereon, and the filter plate 26 located on its motion trajectory is cleaned until the filter plate 26 is reset, at which time the driving of the rotating gear 23 is stopped and the electric telescopic rod 34 is retracted; When the electric telescopic rod 34 is fully retracted, during this process, the displacement plate 35 moves downward, so that the pressure between the upper part of the displacement plate 35 and the inner cavity of the piston box 32 increases. When the displacement plate 35 passes through the connection of the delivery pipe 1 33 on the displacement plate 35, the one-way valve at the connection between the water storage tank 31 and the delivery pipe 1 33 is opened due to the pressure difference, so that the water in the water storage tank 31 enters the inner cavity between the upper part of the displacement plate 35 and the piston box 32, so as to prepare for the next flushing; By means of the inclined baffle plate 110 and the sealing plug provided at the connection between the baffle plate 110 and the rotating shaft 15, the slag and water after cleaning flow into the baffle plate 45 through the baffle plate 110 and are blocked by the inner wall of the baffle plate 45, and then enter the conical groove 43 through the baffle plate 45. Since the conical groove 43 and the filter column 42 are arranged to gradually shrink from left to right, and the part of the output end of the conical threaded feed rod 44 that exceeds the filter column 42 is arranged to be a cylinder with the same minimum annular surface as the conical threaded feed rod 44, the unidirectional motor 49 is started at this time, and the output end of the conical threaded feed rod 44 is driven to rotate by the rotation of the output end of the unidirectional motor 49, thereby transporting the slag and water between the baffle plate 45 and the conical groove 43 to the conical groove 43. Since the filter column 42 is arranged to be a cylinder with filter holes and the part with filter holes is arranged at the receiving end, the unidirectional motor 49 is driven to rotate. The water in the conical groove 43 leaks out of the filter column 42 when passing through the collecting groove 410 under the transmission of the conical threaded feeding rod 44. At the same time, as the conical threaded feeding rod 44 gradually rotates, the distance between the material and the conical groove 43 gradually decreases, so that the residual extract in the material is gradually squeezed out with the continued movement of the conical threaded feeding rod 44, and is discharged through the filter holes on the filter column 42 and drips into the collecting groove 410, and then enters the collecting tank 412 through the collecting groove 410 and the second infusion pipe 411. At the same time, the extruded material residue is discharged through the residue outlet of the conical groove 43. Because the residue materials are connected together after extrusion, the residue materials continue to be discharged at this time until the residue materials collide with the second blocking plate 48, so that the extruded residue materials are disconnected and fall, and then enter the collecting box 414 through the feeding pipe 413; When the filter plate 26 of another flip assembly is to be cleaned, the half gear 14 is driven to rotate in the opposite direction by 90 degrees, and then the above operation is performed to complete the cleaning.
