Description

Technical Field

[0001] This invention relates to the field of marigold granule processing technology, and in particular to a device for treating waste liquid from marigold granule processing. Background Technology

[0002] The processing of marigold granules generates a large amount of press leachate wastewater, which contains a large number of flower mud particles of varying sizes. It is a typical high-suspended-solids organic wastewater in industrial production.

[0003] Currently, traditional wastewater treatment equipment mostly uses single-screen filtration or ordinary cyclone separation structures, which can only intercept large-diameter floral foam particles and cannot effectively remove fine suspended particulate matter in wastewater. This results in low separation accuracy, easy clogging of the filter screen, frequent shutdowns for maintenance, and severely impacts continuous production efficiency. Furthermore, using flocculants to treat the suspended fine floral foam particles in the wastewater requires a long settling time, resulting in low treatment efficiency, and the flocculants may cause secondary pollution.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms "comprising" and "having," and any variations thereof, in this application's specification and the foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in this application's specification and the foregoing drawings are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This invention provides a device for treating waste liquid from marigold granule processing, such as... Figure 1-19 As shown, the marigold granule processing waste liquid treatment device includes: a cyclone separator 1 installed on the main support frame 1, used to separate the marigold filtrate containing flower mud particles after marigold pressing; a main inlet 10 is provided on the side wall of the cyclone separator 1, which is arranged tangentially to the inner side wall of the cyclone separator 1; the marigold pressing filtrate to be treated is pumped into the cyclone separator 1 under high pressure through the main inlet 10 by an external pump, which can improve the initial cyclone effect; with the addition of the cyclone mechanism, the cyclone effect can be further improved and the separation can be accelerated; a horizontal spiral centrifugal separator 2 is used to separate the suspended matter such as tiny particles in the primary separation liquid after separation by the cyclone separator 1; the horizontal spiral centrifugal separator 2 is fixed on the main support frame 9; and an adjusting tank 5 is provided on the main support frame 9 to adjust the pH value of the secondary separation liquid after centrifugation by the horizontal spiral centrifugal separator 2.

[0028] In this embodiment, after the high-pressure waste liquid enters the cyclone separator 1 tangentially, it forms a high-intensity cyclone field with the rotation drive of the cyclone mechanism. This causes large particles of floral foam in the waste liquid to settle against the wall due to their high density under centrifugal force, achieving primary solid-liquid separation. The separated primary liquid is transported to the horizontal spiral centrifugal separator 2, where strong centrifugal force is generated by the differential rotation of the drum 21 and the cylinder 22. This removes fine suspended particles from the waste liquid without a filter screen, effectively avoiding filter clogging and secondary pollution from flocculants. The secondary liquid is transported to the regulating tank 5, where a double cross spray stirring structure, combined with online pH monitoring and acid solution addition mechanism, enables rapid, precise, and uniform adjustment of the waste liquid's pH. The entire device is interconnected and the processes are tightly linked, allowing for fully automatic and continuous completion of waste liquid classification, solid material dehydration, and waste liquid pH adjustment. This improves the waste liquid separation accuracy and floral foam recycling rate, reduces equipment maintenance costs, and is suitable for waste liquid treatment in large-scale marigold processing.

[0029] In a further preferred embodiment of the present invention, the cyclone separator 1 is equipped with a cyclone mechanism, the cyclone mechanism comprising: a rotating shaft 11 that passes through the top of the cyclone separator 1 and is arranged vertically, the rotating shaft 11 being rotatably mounted on the cyclone separator 1, and cyclone blades 12 mounted on the rotating shaft 11, located inside the cyclone separator 1, for causing the marigold leachate to swirl during rotation; a main motor 13 fixed to the top of the cyclone separator 1, and spur gears 14 meshing with each other being fixedly sleeved on both the output shaft of the main motor 13 and the rotating shaft 11.

[0030] In this embodiment, the main motor 13 drives the rotating shaft 11 and the swirl blades 12 to rotate at high speed through the meshing spur gears 14. This works in conjunction with the initial swirling flow formed by the tangential high-pressure liquid inlet to create a stronger and more stable swirling centrifugal field inside the swirling separator 1. This effectively enhances the disturbance and centrifugal sedimentation effect of the waste liquid, accelerates the rapid sedimentation and separation of large-particle flower mud, and improves the efficiency of primary solid-liquid separation.

[0031] In a further preferred embodiment of the present invention, a cyclone separator 1 is installed inside the cyclone separator 1. The cyclone separator 16 is arranged along the inner side wall of the cyclone separator 1 to make the leachate settle rapidly downwards during high-speed cyclone separation, thereby improving the solid-liquid separation efficiency.

[0032] In this embodiment, the spiral blades 16 of the swirling track arranged on the inner side wall of the tank guide and limit the flow of the waste liquid in the swirling state, regulate the swirling trajectory of the waste liquid and guide the mixture carrying the flower mud particles to settle quickly downwards, effectively avoiding the problems of turbulent flow and particle suspension.

[0033] In a further preferred embodiment of the present invention, a primary separation liquid conveying mechanism is installed on the cyclone separator 1. The primary separation liquid conveying mechanism includes: an overflow pipe 18 passing through the hollow hole of the rotating shaft 11, the overflow pipe 18 being sealed and rotatably connected to the hollow inner wall of the rotating shaft 11; a fixing block 17 installed above the cyclone separator 1, the overflow pipe 18 being fixedly connected to the overflow pipe 18; and a booster pump 19 fixed to the top of the cyclone separator 1, the input end of the booster pump 19 being fixedly connected to the top of the overflow pipe 18 through a pipeline, the booster pump 19 being used to convey the primary separation liquid to the horizontal spiral centrifugal separator 2.

[0034] In this embodiment, the clean upper primary separation liquid can be stably drawn out through the overflow pipe 18 that passes through the hollow position of the rotating shaft 11, and then the liquid booster pump 19 provides stable conveying power to quantitatively and steadily deliver the primary separation liquid into the horizontal spiral centrifugal separation mechanism 2, effectively ensuring the continuous connection and stable feeding of the two-stage separation process, avoiding liquid accumulation and retention, and ensuring continuous automated operation of the equipment.

[0035] In a further preferred embodiment of the present invention, the horizontal spiral centrifugal separation mechanism 2 includes: a cylindrical shell 20 and a drum 21 rotatably installed inside the cylindrical shell 20. One end of the drum 21 is provided with several overflow holes, and one section of the drum 21 is conical. A rotating cylinder 22 is rotatably installed inside the drum 21. Spiral pusher blades 23 are installed on the outer wall of the rotating cylinder 22 and contact the inner wall of the drum 21. A straight pipe is installed at one end of the rotating cylinder 22 extending outside the cylindrical shell 20, and several overflow holes are located at the end of the drum 21 away from the straight pipe. A sealed bearing is rotatably mounted on... A transverse sleeve 24 is attached to one end of a straight pipe. One end of the transverse sleeve 24 is connected to the output end of a booster pump 19 via a pipeline, and the transverse sleeve 24 is fixedly connected to a fixed bracket 25 installed on the main support frame 9. The outer wall of the rotating drum 22 has multiple feed holes, which are connected to the straight pipe through a hollow channel inside the rotating drum 22. The primary separation liquid enters the rotating drum 21 through the feed holes. The bottom of the cylindrical shell 20 is provided with a liquid phase outlet 26 and a solid phase outlet 27. The horizontal spiral centrifugal separation mechanism 2 is also equipped with a transmission mechanism for driving the rotating drum 21 and the rotating drum 22 to rotate.

[0036] In this embodiment, the primary separation liquid, delivered by the booster pump 19, enters the interior of the rotating drum 22 through the transverse sleeve 24 and straight pipe supported by the fixed bracket 25, and then enters the interior of the rotating drum 21 evenly through the feed hole on the side wall of the rotating drum 22. The transmission mechanism drives the rotating drum 21 and the rotating drum 22 to rotate synchronously and differentially, so that the waste liquid forms a strong centrifugal force field inside the rotating drum 21. Under the centrifugal action, the fine suspended particles in the waste liquid adhere to the inner wall of the rotating drum 21, and are then continuously pushed to the conical section by the spiral pusher blades 23 on the outer wall of the rotating drum 22 to complete the extrusion and dehydration. Finally, the solid phase impurities are discharged from the solid phase outlet 27, and the clarified liquid phase flows out through the overflow hole and is discharged from the liquid phase outlet 26. The whole adopts a filterless centrifugal separation method, which can stably remove the fine suspended matter in the primary separation liquid, completely avoiding the defects of traditional filter structures that are easy to clog and require the addition of flocculants to cause secondary pollution. The separation is continuous, stable, and has high separation accuracy.

[0037] In a further preferred embodiment of the present invention, two outer ring blocks 28 are rotatably mounted on the outer wall of the drum 21 via sealed bearings. Both outer ring blocks 28 are fixed and sealed to the inner wall of the cylindrical shell 1. The drum 21 has multiple discharge holes, and the discharge holes and the solid phase outlet 27 are located between the two outer ring blocks 28. A first support ring block 29 is rotatably mounted on the outer wall of the end of the drum 21 away from the transverse sleeve 24 via a bearing, and multiple connecting blocks 30, each fixed to the inner wall of the cylindrical shell 20, are fixedly mounted on the outer wall of the first support ring block 29. An inner ring block 31 and a second support ring block 32 are rotatably mounted on the drum 22 via sealed bearings. The outer wall of the inner ring block 31 is fixedly connected to the inner wall of the drum 21, and the outer wall of the second support ring block 32 is fixedly connected to the inner wall of the cylindrical shell 20.

[0038] In this embodiment, the outer ring block 28, the first support ring block 29, the connecting block 30, the inner ring block 31, and the second support ring block 32 cooperate with each other to form an all-round limiting support and sealing isolation for the rotating drum 21 and the rotating cylinder 22, so that the rotating drum 21 and the rotating cylinder 22 can rotate stably and differently. At the same time, through the sealing and isolation effect of the outer ring block 28, the discharge hole and solid phase outlet 27 of the rotating drum 21 are limited to an independent sealed cavity, effectively preventing the liquid phase from entering the solid phase discharge area and ensuring strict solid-liquid separation. The inner ring block 31 and the second support ring block 32 can coaxially position the rotating cylinder 22 to prevent eccentric shaking and wear during rotation, greatly improving the stability and sealing of the horizontal spiral centrifugal separator 2, reducing equipment failure, and continuously ensuring the continuity and reliability of micro-particle centrifugal separation and discharge.

[0039] In a further preferred embodiment of the present invention, the transmission mechanism includes: a U-shaped seat 33 fixed on the main support frame 9, a vertical shaft 34 rotatably mounted on the U-shaped seat 33 via bearings, and pulleys 35 fixedly mounted on both the vertical shaft 34 and the output shaft of the main motor 13, the two pulleys 35 being connected by a belt 36; a horizontal shaft 37 rotatably mounted on the inner wall of one side of the U-shaped seat 33 via bearings, and bevel gears 38 meshing with each other fixedly mounted on both the horizontal shaft 37 and the vertical shaft 34; a double-groove pulley 39 fixedly mounted on the horizontal shaft 37; and pulleys 40 and 41 fixedly mounted on the drum 21 and the cylinder 22 respectively, the pulleys 40 and 41 being connected to the double-groove pulley 39 via a belt 42, and the diameter of the pulley 41 being larger than the diameter of the pulley 40.

[0040] In this embodiment, the main motor 13 drives the vertical shaft 34 to rotate via pulley 35 and belt 36, and then transmits the power to the horizontal shaft 37 via meshing bevel gear 38, causing the horizontal shaft 37 to drive the double-groove pulley 39 to rotate synchronously. The double-groove pulley 39 is linked to pulley 40 and pulley 41 via belt 42, thereby synchronously driving the drum 21 and the cylinder 22 to rotate. The difference in diameter between pulley 41 and pulley 40 creates a stable speed difference, enabling the drum 21 and the cylinder 22 to rotate in a differentiated coaxial manner, providing stable power for the centrifugal sedimentation and solid-phase feeding dewatering of the horizontal spiral centrifugal separation mechanism 2. The entire transmission structure relies on the original main motor 13 to achieve linkage drive, without the need for additional drive equipment. The structure is compact, the transmission synchronization is good, and it can continuously ensure the stable and continuous operation of the centrifugal separation process.

[0041] In a further preferred embodiment of the present invention, a protective box 15 is installed on the top of the cyclone separator 1, and both spur gears 14 are located inside the protective box 15; a protective box 2 is installed on one inner wall of the U-shaped seat 33, and both bevel gears 38 are located inside the protective box 2.

[0042] In this embodiment, the protective box 15 completely covers and protects the meshing spur gear 14, which can prevent moisture, dust and impurities from entering the gear meshing area, avoid gear wear, jamming and corrosion, and ensure smooth and stable transmission of the vortex mechanism. At the same time, the protective box 2 set inside the U-shaped seat 33 can provide closed protection for the bevel gear 38, effectively isolate pollutants in the working environment and extend the service life of the transmission components.

[0043] In a further preferred embodiment of the present invention, the regulating tank 5 is provided with a secondary separation liquid conveying mechanism for conveying the secondary separation liquid separated by the horizontal spiral centrifugal separator 2 into the regulating tank 5. The secondary separation liquid conveying mechanism includes: a liquid pump 50 fixedly installed on the main support frame 9, the input end of the liquid pump 50 being connected to the liquid phase outlet 26 through a pipeline; a fixed pipe 52 fixedly installed on the inner wall of the bottom of the regulating tank 5, the bottom end of the fixed pipe 52 being connected to the output end of the liquid pump 50 through a connected conveying pipe 51; and a rotating pipe 53 rotatably installed at the top of the fixed pipe 52 through a sealed bearing, the top end of the rotating pipe 53 being fixedly installed with a lower cross pipe 54 connected to the rotating pipe 53, the top of the lower cross pipe 54 having several upper spray holes 55, and the ends of the lower cross pipe 54 being all closed.

[0044] In this embodiment, the liquid pump 50 continuously transports the secondary separated liquid, which has been centrifuged and purified by the horizontal spiral centrifugal separator 2, to the regulating tank 5 via the conveying pipe 51 and the fixed pipe 52. The liquid is sprayed out through the upper spray hole 55 at the top of the lower cross pipe 54, so as to realize the stable and quantitative delivery and uniform distribution of waste liquid, and provide stable water intake conditions for subsequent pH adjustment operations.

[0045] In another embodiment of the present invention, an acid solution adding mechanism is installed on the main support frame 9, including: a storage tank 56 for storing acid solution, a lower pipe 57 installed at the bottom of the storage tank 56, a solenoid valve and a metering pump mounted on the lower pipe 57 for adding acid solution to the regulating tank 5; a vertical sleeve 58 rotatably sleeved at the bottom end of the lower pipe 57 via a sealed bearing, the vertical sleeve 58 being rotatably connected to the top of the regulating tank 5 via a bearing; an upper cross tube 59 fixedly connected to the bottom end of the vertical sleeve 58 and communicating with the vertical sleeve 58, located inside the regulating tank 5 and directly above the lower cross tube 54, the bottom of the upper cross tube 59 having several lower spray holes 60, and all ports of the upper cross tube 59 being closed.

[0046] In this embodiment, the acid solution inside the storage tank 56 can be quantitatively and controllably delivered through the solenoid valve and metering pump on the lower pipe 57. The acid solution is sent into the upper cross tube 59 through the vertical sleeve 58 and sprayed downward from the bottom spray hole 60. The upper cross tube 59 is arranged directly above the lower cross tube 54, so that the acid solution and the upward sprayed secondary separation liquid form a convective mixing spray. Combined with the rotatable installation structure, the acid-base contact mixing range can be greatly increased, realizing the rapid and uniform mixing of the acid solution and the secondary separation liquid, effectively improving the pH adjustment accuracy and mixing efficiency.

[0047] In a further preferred embodiment of the present invention, an installation box 66 is provided on the conveying pipe 51, the conveyed secondary separation liquid passes through the installation box 66, and a pH monitoring sensor is installed on the installation box 66 to monitor the pH value of the secondary separation liquid before adjustment; a pH monitoring sensor is also installed on one side of the adjustment tank 5 to monitor the pH value of the mixture.

[0048] In this embodiment, the mounting box 66 on the delivery pipe 51 has a built-in pH monitoring sensor, which can monitor the original pH value of the secondary separation liquid before entering the regulating tank 5 in real time. At the same time, the pH monitoring sensor installed on the side wall of the regulating tank 5 can collect the acid and alkali data of the mixed liquid in the tank in real time. Through real-time detection of pH before and after, the acid and alkali changes of the waste liquid can be accurately fed back. Combined with the quantitative addition function of the acid solution addition mechanism, the acid solution can be added accurately as needed, which can effectively improve the accuracy and stability of the pH adjustment of the waste liquid, avoid the problem of over-adjustment or under-adjustment, and ensure that the pH of the treated waste liquid is uniformly up to standard.

[0049] In another embodiment of the present invention, a plurality of horizontal nozzles 61 are installed on the side wall of the lower cross tube 54. When the plurality of horizontal nozzles 61 spray out the secondary separation liquid, the lower cross tube 54 rotates due to the reaction force of the air. A splined vertical rod 62 is fixedly installed on the top of the lower cross tube 54, and a splined sleeve rod 63 is fixedly installed on the bottom of the upper cross tube 59. The bottom end of the splined sleeve rod 63 is sleeved on the top end of the splined vertical rod 62 and they are engaged. In this way, when the secondary separation liquid is pumped into the regulating tank 5 by the liquid pump 50 and sprayed out, the lower cross tube 54 rotates, and drives the upper cross tube 59 to rotate through the splined vertical rod 62 and the splined sleeve rod 63. In this way, the sprayed secondary separation liquid and acid solution are mixed well and quickly.

[0050] In this embodiment, when the secondary separation liquid is sprayed out through the horizontal nozzle 61 on the side wall of the lower cross tube 54, the fluid jet reaction force drives the lower cross tube 54 to rotate automatically. At the same time, the lower cross tube 54 drives the upper cross tube 59 to rotate synchronously through the meshing transmission of the spline vertical rod 62 and the spline sleeve rod 63. This causes the secondary separation liquid and the acid solution to form a dynamic cross-jet mixed flow in the regulating tank 5. The two sets of spray structures can be synchronously rotated and sprayed without additional drive components, which greatly expands the liquid mixing range, accelerates the acid-base neutralization reaction rate, and makes the mixing of the secondary separation liquid and the acid solution more uniform and efficient.

[0051] In another embodiment of the present invention, a horizontal stirring rod 64 is fixedly sleeved on the rotating pipe 53, and a plurality of vertical stirring rods 65 are fixedly installed at the bottom of the horizontal stirring rod 64 for stirring the liquid in the regulating tank 5, so as to further mix the liquid and improve the pH adjustment effect of the secondary separation liquid; and a drain pipe 67 is provided at the bottom of the regulating tank 5, and a solenoid valve is provided on the drain pipe 67.

[0052] In this embodiment, as the rotating pipe 53 rotates synchronously with the lower cross pipe 54, it drives the horizontal stirring rod 64 and the vertical stirring rod 65 to rotate and stir synchronously inside the regulating tank 5. This secondary agitation and mixing of the sprayed waste liquid and acid further eliminates local concentration differences, improves the uniformity and stability of the pH adjustment of the waste liquid, effectively enhances the acid-base neutralization effect, and ensures that the regulated water quality consistently meets the standards. At the same time, the bottom of the regulating tank 5 is equipped with a drain pipe 67 with a solenoid valve, which can accurately and controllably discharge the liquid after the waste liquid is regulated, and then transport it to the subsequent treatment process (the subsequent treatment process is not within the scope of the technical solution of this invention and will not be described in detail).

[0053] In another embodiment of the present invention, the bottom end of the cyclone separator 1 is provided with an opening and closing mechanism for opening and closing the bottom outlet of the cyclone separator 1. The mechanism includes: a horizontal sliding hole 68 formed at the bottom end of the cyclone separator 1, and a baffle 69 slidably installed thereon to block the bottom outlet of the cyclone separator 1; two connecting rods 70 fixedly installed on one side of the baffle 69, with the same strip plate 71 fixed at the same end of the two connecting rods 70; and two electric push rods 72 respectively fixed on the two side walls at the bottom end of the cyclone separator 1. The two electric push rods 72 are horizontally arranged, and the output rods of the two electric push rods 72 are fixedly connected to the strip plate 71. When the output rods of the two electric push rods 72 extend, the bottom outlet of the cyclone separator 1 is opened, thereby discharging the swirling and settling flower mud particles.

[0054] In this embodiment, the electric push rod 72 at the bottom of the cyclone separator 1 can drive the baffle 69 to slide horizontally within the horizontal sliding hole 68 through the strip plate 71 and the connecting rod 70, thereby realizing automatic opening and closing control of the bottom discharge port. During the cyclone separation operation, the baffle 69 closes the discharge port to ensure the stability of the pressure and cyclone field inside the tank, ensuring efficient sedimentation of the floral foam particles. When discharge is required, the electric push rod 72 extends to push the baffle 69 to slide and open the discharge port, which can automatically discharge the settled floral foam particles downwards, realizing automated discharge of settled impurities without manual cleaning, effectively ensuring the continuous and stable operation of the cyclone separator 1, and improving the overall automation level and continuous operation capability of the equipment.

[0055] In another embodiment of the present invention, a spiral extrusion mechanism for further dehydrating the separated marigold mud is also installed on the main support frame 9, located below the cyclone separator 1 and the horizontal spiral centrifugal separator 2. The spiral extrusion mechanism includes: a horizontal outer shell 73 fixedly installed on the main support frame 9, with a horizontal inner filter cylinder 74 fixed inside; an installation shaft 75 rotatably installed inside the horizontal inner filter cylinder 74, on which two spiral extrusion blades 76 with opposite rotation directions are installed, and the blade spacing of the two spiral extrusion blades 76 gradually decreases from the ends that are far apart to the ends that are close to each other; an auxiliary motor 77 fixed to one end of the horizontal outer shell 73, the output shaft of the auxiliary motor 77 being fixedly connected to one end of the installation shaft 75 by a coupling; wherein, two drain ports 84 are installed at the bottom of the horizontal outer shell 73, and a discharge port 85 is installed at the bottom of the middle section of the horizontal inner filter cylinder 74, the bottom end of the discharge port 85 extending outside the horizontal outer shell 73.

[0056] In this embodiment, the floral foam particles discharged from the cyclone separator 1 and the horizontal spiral centrifugal separator 2 fall into the lower spiral extrusion mechanism. The auxiliary motor 77 drives the mounting shaft 75 to rotate through the coupling, which drives the two spiral extrusion blades 76 with opposite rotation directions to rotate synchronously and push the floral foam material. The distance between the two spiral extrusion blades 76 gradually decreases from the outside to the middle, so that the material is subjected to progressively increasing extrusion during the conveying process. In conjunction with the horizontal inner filter cartridge 74, solid-liquid separation is achieved. The water squeezed out is discharged through the drain port 84 at the bottom of the horizontal outer shell 73. The dehydrated dry floral foam is finally discharged through the discharge port 85, realizing deep dehydration and recycling of floral foam material and effectively improving the utilization rate of floral foam.

[0057] In another embodiment of the present invention, a feeding cylinder 78 is fixedly installed at the bottom of the cyclone separator 1 and the bottom of the cylindrical shell 20. The two feeding cylinders 78 are respectively adapted to the discharge port at the bottom of the cyclone separator 1 and the solid phase outlet 27 at the bottom of the cylindrical shell 20. A linkage feeding mechanism is installed in each of the two feeding cylinders 78. The linkage feeding mechanism includes: a feeding shaft 79 disposed in the feeding cylinder 78, on which a spiral feeding blade 80 is installed; a fixing box 81 disposed in the horizontal inner filter cartridge 74, on which a plurality of fixing rods 82 are fixedly connected to the outer wall of the fixing box 81, and the other end of each fixing rod 82 is fixedly connected to the inner wall of the horizontal inner filter cartridge 74; and two bevel gears 83 respectively fixedly sleeved on the bottom end of the feeding shaft 79 and the mounting shaft 75, the two bevel gears 83 meshing with each other.

[0058] In this embodiment, when the mounting shaft 75 of the spiral extrusion mechanism is in operation, it synchronously drives the feeding shaft 79 to rotate through the meshing bevel gears 83, causing the spiral feeding blades 80 in the feeding cylinder 78 to rotate synchronously and feed material. The flower foam particles separated and settled by the cyclone separator 1 and the cylindrical shell 20 can be continuously and evenly transported to the interior of the horizontal inner filter cylinder 74 through the feeding cylinder 78. The fixed box 81 and the fixed rod 82 provide stable support for the transmission structure. The entire linkage feeding mechanism can achieve automatic synchronous feeding without an additional power source, ensuring that the solid flower foam is continuously and stably fed into the spiral extrusion mechanism for deep dehydration, effectively avoiding the problems of material accumulation and blockage, realizing the linkage matching of the separation feeding and extrusion dehydration processes, and improving the overall automated collaborative operation effect of the equipment.

[0059] It is worth noting that the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods. In summary, compared with related technologies, this invention adopts an integrated linkage structure that combines cyclone separation, centrifugal fine separation, precise pH adjustment, and floral foam extrusion dehydration. Through high-pressure tangential liquid inlet combined with a cyclone mechanism and a spiral guide structure, the efficiency of primary solid-liquid separation of waste liquid is significantly improved. Relying on a filterless horizontal spiral centrifugal structure, it effectively solves the technical problems of traditional filters being prone to clogging and requiring the addition of flocculants to cause secondary pollution. Simultaneously, the device uses a shared drive motor for linkage transmission, coupled with a double-cross reverse spray, dynamic stirring, and a dual-point pH monitoring structure at both ends, achieving precise and uniform adjustment of the waste liquid's acidity and alkalinity. Furthermore, the linkage feeding mechanism completes the automatic continuous feeding and deep dehydration of floral foam.
