Description

Technical Field

[0001] This invention relates to the field of mixer technology, specifically a multi-helix synergistic coupling mixer for deep-sea mining. Background Technology

[0002] One of the core challenges of deep-sea mining systems lies in the in-situ pretreatment of the collected materials. Polymetallic nodules often coexist with thick layers of seabed clay. The material collected by the sampling head is a solid-liquid two-phase mixture with an extremely wide particle size distribution, ranging from micron-sized clay particles to centimeter-sized or even larger nodule lumps. Existing pretreatment devices are mostly single-function equipment. Currently commonly used deep-sea mining mixers mainly include single-spiral mixers and double-spiral stirring mixers. For example, the single-spiral static mixer in patent application number CN202120384715.7 relies solely on the pushing and stirring action of a single spiral, lacking a targeted crushing structure design. Another example is the double-spiral conical mixer in patent application number CN202222630458.8, which, although employing a double-spiral layout, lacks a synergistic crushing mechanism due to the spiral direction and spacing design. None of these solutions can efficiently and reliably complete the integrated crushing, mixing, and conveying of complex deep-sea materials within a limited space.

[0003] Existing technological solutions suffer from the following significant drawbacks, severely restricting the efficiency and environmental adaptability of deep-sea mining: 1. Insufficient grinding and poor mixing uniformity Existing mixers mostly adopt a single or double helix structure, relying solely on the rotation and impact of the helical blades to achieve crushing. They lack targeted biomimetic optimization design, making it difficult to completely crush multi-metallic nodules with high hardness and large particles. At the same time, the unreasonable helix layout results in a short residence time of materials in the mixing chamber, leading to uneven mixing of the crushed minerals with the conveying medium, which affects the efficiency of subsequent separation and purification.

[0004] 2. Low conveying efficiency and severe cavitation. The conveying screws of existing mixers are mostly conventional straight or simple arc-shaped structures, lacking turbulence design. When rotating at high speed, they are prone to generating unstable turbulence, resulting in high material conveying resistance and low efficiency. At the same time, the cavitation phenomenon caused by turbulence will erode the screw blades, shorten the service life of the mixer, and increase the equipment replacement cost. Summary of the Invention

[0005] This invention provides a multi-helix synergistic coupling mixer for deep-sea mining, aiming to solve the problems of insufficient crushing, low conveying efficiency, high energy consumption and insufficient stability of the above-mentioned deep-sea mining mixers.

[0006] To achieve the above objectives, the present invention provides a multi-helix cooperative coupling mixer for deep-sea mining, comprising: The housing has a feed inlet for feeding and a discharge outlet for discharging. The spiral cutting blade is rotatably located at the front of the housing and below the feed inlet; The biomimetic toothed spiral blade is rotatably located at the front of the housing and below the feed inlet; The biomimetic fin-shaped spiral blade is connected to the end of the spiral cutting blade and the biomimetic toothed spiral blade, and rotates to be located in the rear of the shell, so that the material is crushed and discharged through the discharge port; The spiral cutting blade, biomimetic toothed spiral blade, and biomimetic fin spiral blade are configured to rotate synchronously within the housing and form a triangular structure to classify, crush, and convey the material entering the housing.

[0007] Preferably, there is one spiral cutting blade, two biomimetic toothed spiral blades, and three biomimetic fin spiral blades, so that the spiral cutting blade, biomimetic toothed spiral blades, and biomimetic fin spiral blades form an equilateral triangle structure that rotates synchronously within the shell.

[0008] Preferably, the outer ring of the biomimetic tooth spiral plate is evenly and spaced along the spiral direction with a tooth-like structure similar to that of a crab-eating seal; the blades of the biomimetic fin spiral plate are evenly and spaced along the spiral direction with multiple sets of fish fin-shaped protrusions, located on the front and back sides of the biomimetic fin spiral plate.

[0009] Preferably, each group of fish-fin-shaped protrusions includes multiple rows of fish-fin-like plates, which are arranged axially opposite each other on the front and back sides of the biomimetic fin spiral plate.

[0010] Furthermore, each group of fish-fin-shaped protrusions includes three rows of fish-fin-like plates, which are combinations of one, two, and three plates, respectively.

[0011] Furthermore, each group of fish-fin-shaped protrusions includes two rows of fish-fin-like plates, with the two rows of fish-fin-like plates consisting of combinations of two and three plates, respectively.

[0012] Preferably, it further includes a drive mechanism for driving the spiral cutting blade, the bionic toothed spiral blade, and the bionic fin spiral blade to rotate synchronously within the housing. The drive mechanism is located at one end of the housing to drive the spiral cutting blade, the bionic toothed spiral blade, and the bionic fin spiral blade to rotate in opposite directions or in the same direction within the housing.

[0013] The drive mechanism includes: The drive motor is located at one end of the housing; The gear ring is fixedly mounted at one end of the housing; The sun gear is rotatably mounted at one end of the housing and connected to the output end of the drive motor; The planetary gear meshes with the sun gear and the gear ring. The spiral cutting blade, the bionic toothed spiral blade, and the bionic fin spiral blade are coaxially connected to the planetary gear via rotating shafts. The planet carrier rotates on the gear ring, and the planet gears rotate on the planet carrier.

[0014] Preferably, it also includes a circumferential gear and a coaxial gear. The rotating shaft rotates through the planetary gear and is coaxially connected to the coaxial gear. The circumferential gear is fixed between multiple coaxial gears and meshes with the coaxial gear for transmission, so that the coaxial gear revolves and rotates in the same direction on the circumferential gear under the drive of the sun gear.

[0015] Preferably, the end of the housing is provided with a limiting mechanism for supporting the synchronous rotation of the spiral cutting blade, the biomimetic toothed spiral blade, and the biomimetic fin spiral blade; the limiting mechanism includes: An annular ring is fixedly installed at the other end of the housing; The limiting frame is rotatably mounted on the annular ring, and the rotating shaft is rotatably mounted on the limiting frame; The sealing cap is fixed to the annular ring by bolts.

[0016] It also includes a circumferential gear and a coaxial gear. The circumferential gear is coaxially connected to the end of the shaft and located inside the annular ring. The coaxial gear is fixed in the middle of the sealing cover and meshes with multiple circumferential gears to drive the circumferential gear to make it revolve and rotate in the same direction on the coaxial gear under the drive of the sun gear.

[0017] Compared with existing technologies, it has the following beneficial effects: (1) The powder is fully and evenly crushed, resulting in high mixing efficiency. The structure employs a triple-helix synergistic crushing design with an equilateral triangle layout. The biomimetic toothed helical blades achieve initial crushing through extrusion, while the helical cutting blades perform secondary fine crushing. The staged crushing design ensures that the minerals are fully crushed. The synergistic rotation of the three helices increases the residence time and contact area of ​​the material in the cavity, making the crushed minerals and the conveying medium mix evenly and improving the efficiency of subsequent separation and purification.

[0018] (2) The conveying is efficient and stable, and the service life is long. The textured array of the biomimetic fin spiral blades plays a highly efficient role in turbulence, suppressing turbulence and cavitation. This reduces material conveying resistance, improves conveying efficiency, and prevents cavitation from eroding the blades. At the same time, the large-size, thin design of the spiral blades further optimizes the conveying effect and extends the overall service life of the equipment.

[0019] (3) Excellent power coordination and low energy consumption The spiral cutting blade, biomimetic toothed spiral blade, and biomimetic fin spiral blade revolve and rotate in a coordinated manner, and the crushing, mixing, and conveying functions are coupled and linked. The optimized transmission structure reduces energy loss. The staged crushing and efficient mixing design avoids repetitive work, and the energy consumption is reduced by more than 30% compared with the existing mixer, which meets the low energy consumption requirements of deep-sea mining.

Detailed Implementation To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: Example 1: like Figures 1 to 7 As shown, the present invention provides a multi-helix cooperative coupling mixer for deep-sea mining, comprising: The housing 1 has a feed inlet 11 for feeding and a discharge outlet 12 for discharging. The spiral cutting blade 2 is rotatably located at the front of the housing 1 and below the feed inlet 11; The biomimetic toothed spiral blade 3 is rotatably disposed in the front part of the housing 1 and located below the feed inlet 11; The biomimetic fin spiral blade 4 is connected to the ends of the spiral cutting blade 2 and the biomimetic tooth spiral blade 3, and rotates to be located in the rear part of the housing 1, so that the material is crushed and discharged through the discharge port 12; The spiral cutting blade 2, the biomimetic toothed spiral blade 3, and the biomimetic finned spiral blade 4 are configured to rotate synchronously within the housing 1 and form a triangular structure to classify, crush, and convey the material entering the housing 1.

[0023] See Figures 1 to 4 The system consists of one spiral cutting blade 2, two biomimetic toothed spiral blades 3, and three biomimetic fin-shaped spiral blades 4, forming an equilateral triangle structure that rotates synchronously within the housing 1. The biomimetic toothed spiral blade 3 employs a dual-axis design, with both axes located on the same horizontal line. The rotating shaft 5 of the spiral cutting blade 2 and the two rotating shafts 5 of the biomimetic toothed spiral blade 3 form an equilateral or isosceles triangle layout, creating a three-spiral synergistic crushing mixing system. The biomimetic fin-shaped spiral blade 4, located at the end of the mixing system, is larger and thinner than the other two, and is used for material conveying. The spiral cutting blade 2, through high-speed rotation, achieves secondary fine crushing of the remaining large particles after crushing by the biomimetic toothed spiral blade 3, ensuring uniform mineral particle size to meet subsequent mixing and conveying requirements.

[0024] See Figure 5The outer ring of the biomimetic toothed spiral blade 3 is evenly and spaced with crab-eating seal tooth-like structures 31 along the spiral direction; the blades of the biomimetic fin spiral blade 4 are evenly and spaced with multiple sets of fish fin-shaped protrusions 41 along the spiral direction, located on the front and back sides of the biomimetic fin spiral blade 4. The biomimetic crab-eating seal tooth-like structures of the biomimetic toothed spiral blade 3, with the two biomimetic toothed spiral blades 3 closely arranged and not intersecting each other, perform preliminary crushing of large minerals through the squeezing action during rotation, and utilize the biomimetic crab-eating seal tooth-like structures 31 to improve crushing efficiency and adaptability.

[0025] See Figure 6 Each group of fish-fin-shaped protrusions 41 includes multiple rows of fish-fin-like plates. The multiple rows of fish-fin-like plates are arranged axially opposite each other on the front and back sides of the bionic fin spiral plate 4 so as to rotate together with the bionic fin spiral plate 4 to play a turbulence role.

[0026] Furthermore, each group of fish-fin-shaped protrusions 41 includes three rows of fish-fin-like plates, the three rows of fish-fin-like plates being combinations of one, two, and three plates respectively. As an alternative, each group of fish-fin-shaped protrusions 41 may also include two rows of fish-fin-like plates, the two rows of fish-fin-like plates being combinations of two and three plates respectively.

[0027] The fish-fin-like blades on the biomimetic fin spiral blade 4 are arranged in an array layout of "two in a row and three in a row", or in an array layout of "three in a row, two in a row and one in a row" in a decreasing order. When rotating at high speed, the fish-fin-like blades play a turbulence role, suppressing the generation of unstable turbulence, reducing material conveying resistance and improving conveying efficiency. At the same time, the turbulence effect can reduce the occurrence of cavitation, prevent the blades from being eroded by cavitation, and extend the service life of the mixing system.

[0028] Furthermore, in addition to using a triple helix combination of helical cutting blade 2, biomimetic toothed helical blade 3, and biomimetic finned helical blade 4, the present invention can also replace the helical cutting blade 2 with a biomimetic shark tooth cutting blade, thereby improving the crushing efficiency through a sharper biomimetic tooth shape.

[0029] Furthermore, the three-helix combination of the spiral cutting blade 2, the biomimetic toothed spiral blade 3, and the biomimetic fin spiral blade 4 can be transformed into a four-helix combination with a square layout to further optimize the mixing uniformity; the texture of the biomimetic fin spiral blade 4 can be replaced with a biomimetic whale fin texture, which can also achieve the effect of turbulence prevention and cavitation prevention.

[0030] The working principle of this embodiment is as follows: the material enters the housing 1 through the feed port 11 at the front end of the housing 1, and is first crushed and conveyed by the crushing system consisting of two bionic toothed spiral blades 3 and one spiral cutting blade 2. After crushing, the material is conveyed to the conveying system consisting of three bionic fin spiral blades 4, and the crushed material is discharged from the discharge port 12 through the three bionic fin spiral blades 4.

[0031] Example 2: As another embodiment of the present invention, such as Figures 7 to 9 As shown, a multi-helix cooperative coupling mixer for deep-sea mining also includes a drive mechanism 6 for driving the helical cutting blade 2, the bionic toothed helical blade 3, and the bionic finned helical blade 4 to rotate synchronously within the housing 1. The drive mechanism 6 is located at one end of the housing 1 to drive the helical cutting blade 2, the bionic toothed helical blade 3, and the bionic finned helical blade 4 to perform counter-revolutionary and rotational motions within the housing 1.

[0032] Drive mechanism 6 includes: The drive motor 61 is located at one end of the housing 1 and is sealed for protection; Gear ring 62 is fixedly mounted at one end of housing 1; The sun gear 63 is rotatably mounted at one end of the housing 1 and connected to the output end of the drive motor 61; further, the output end of the drive motor 61 is connected to the sun gear 63 through a reducer or a gearbox, and the reducer or gearbox is fixed to the gear ring 62 through the end cover 66. Planetary gear 64 meshes with sun gear 63 and gear ring 62. Spiral cutting blade 2, bionic tooth spiral blade 3 and bionic fin spiral blade 4 are coaxially connected to planetary gear 64 via rotating shaft 5. The planet carrier 65 is rotatably mounted on the smooth inner wall of the gear ring 62, and the planet gears 64 are rotatably mounted on the planet carrier 65, so that the planet gears 64 rotate on their own axes on the planet carrier 65 and revolve within the gear ring 62. The planet carrier 65 has a circular structure and is rotatably mounted on the smooth inner wall of the gear ring 62 via bearings to prevent material from entering the gear ring 62.

[0033] The drive motor 61 drives the sun gear 63 to rotate, thereby driving three or four planet gears 64 to rotate synchronously and revolve synchronously within the gear ring 62, so that the spiral cutting blade 2, the bionic toothed spiral blade 3 and the bionic finned spiral blade 4 rotate synchronously while rotating.

[0034] Furthermore, the driving method is not limited to the drive motor 61, but can also use a hydraulic motor. In addition, it includes an intelligent control system that dynamically adjusts the speed and direction of each shaft 5 according to the real-time current (torque feedback) of the drive motor 61 to achieve adaptive crushing and overload protection.

[0035] See Figure 8 The end of the housing 1 is provided with a limiting mechanism 7 for supporting the synchronous rotation of the spiral cutting blade 2, the biomimetic toothed spiral blade 3, and the biomimetic finned spiral blade 4; the limiting mechanism 7 includes: An annular ring 71 is fixedly disposed at the other end of the housing 1; The limiting frame 72 is rotatably mounted on the annular ring 71 via a bearing, and the rotating shaft 5 is rotatably mounted on the limiting frame 72; The sealing cap 73 is fixed to the annular ring 71 by bolts.

[0036] By setting a limiting mechanism 7, the ends of the synchronously rotating spiral cutting blade 2, bionic tooth spiral blade 3, and bionic fin spiral blade 4 are limited, so that they can revolve and rotate stably within the housing 1.

[0037] The working principle of this embodiment is as follows: The drive motor 61 drives the planetary gears 64 through the sun gear 63 to drive the rotating shaft 5 to rotate synchronously, thereby causing the spiral cutting blade 2, the bionic toothed spiral blade 3, and the bionic fin spiral blade 4 mounted on the rotating shaft 5 to rotate together; during the rotation of the planetary gear 64, under the action of the gear ring 62 and the planetary carrier 65, it moves around the sun gear 63 in a circumferential motion, thereby driving the spiral cutting blade 2, the bionic toothed spiral blade 3, and the bionic fin spiral blade 4 to revolve within the housing 1, so that the spiral cutting blade 2, the bionic toothed spiral blade 3, and the bionic fin spiral blade 4 can revolve synchronously in opposite directions and rotate on their own axis within the housing 1.

[0038] Example 3: As another embodiment of the present invention, such as Figures 10 to 12 As shown, a multi-helix cooperative coupling mixer for deep-sea mining also includes a circumferential gear 8 and a co-rotating gear 9. The circumferential gear 8 is coaxially connected to the end of the rotating shaft 5 and located inside the annular ring 71. The co-rotating gear 9 is fixed to the middle of the sealing cover 73 and meshes with multiple circumferential gears 8 for transmission, so that the circumferential gear 8 revolves and rotates in the same direction on the co-rotating gear 9 under the drive of the sun gear 63.

[0039] The drive motor 61 drives the planetary gear 64 to rotate within the gear ring 62 via the sun gear 63. The rotating shaft 5, which is rotatably connected to the planetary gear 64, moves circumferentially within the housing 1 along with the planetary gear 64. This causes the circumferential gear 8 connected to the end of the rotating shaft 5 to rotate within the housing 1 under the meshing action of the fixedly set co-rotating gear 9. The direction of the rotation is the same as the circumferential direction.

[0040] Specifically, see Figure 13 and Figure 14 This is a standardized pulverizing and conveying model of a multi-spiral cooperative coupling mixer built using Rocky 2024 R1 simulation software. Figure 13 Simulation cloud diagram of the crushing and conveying model when the spiral cutting blade 2, the biomimetic toothed spiral blade 3, and the biomimetic finned spiral blade 4 rotate in opposite directions. Figure 14 Simulation cloud diagrams of the crushing and conveying model when the spiral cutting blade 2, biomimetic toothed spiral blade 3, and biomimetic finned spiral blade 4 rotate in the same direction (both revolution and rotation); through comprehensive analysis of the particle size, distribution, and conveying performance of the crushed material, the following technical effect comparisons are presented: I. Comparison of Particle Distribution Figure 13 (The revolution of axis 5 is in the opposite direction to its rotation): Distribution state: The particles crushed by the spiral cutting blade 2 and the biomimetic toothed spiral blade 3 in the mixing chamber show a significantly sparse distribution. The spacing between particles is large and the distribution is uneven. There is no obvious aggregation area and no continuous flow of material particles is formed. Some particles are dispersed and floating or locally stagnant, reflecting that the particles lack an effective driving force for aggregation after crushing.

[0041] Figure 14 (The revolution and rotation directions of axis 5 are the same): Distribution state: The particles crushed by the spiral cutting blade 2 and the biomimetic toothed spiral blade 3 in the mixing chamber exhibit a uniform and dense distribution. The particles are arranged compactly and regularly, forming a continuous and stable particle aggregation zone with no obvious dispersion breakpoints. The particles can quickly converge along the advancing direction of the spiral blade to form an orderly material flow with extremely low dispersion loss, demonstrating a strong directional conveying driving force.

[0042] II. Comparison of the effects of core conveying technologies (1) Conveying efficiency Figure 13 (The rotation direction of the 5th shaft is opposite to its rotation direction): Due to the sparse distribution of particles and the large average particle size, the effective conveying channel in the mixing chamber is not fully utilized. During the conveying process, the particles are easily affected by their own particle size and dispersion state, resulting in diffusion, stagnation, or even local accumulation. The amount of material that advances along the preset path per unit time is small, the overall conveying efficiency is low, and the conveying effect is weak.

[0043] Figure 14 (The rotation direction of the 5th shaft is the same as its revolution and rotation direction): The dense and uniform particle distribution and finer particle size allow the material to fully fill the conveying channel, enhancing the synergistic propulsion between particles, reducing ineffective diffusion and residence time. Simultaneously, the finer particle size provides better flowability, reducing conveying resistance and significantly increasing the amount of material conveyed per unit time, resulting in higher conveying efficiency. Figure 1 Significant improvement and better delivery effect.

[0044] (2) Conveying stability Figure 13 (The rotation direction of the 5th shaft is opposite to its own rotation direction): Sparse and uneven particle distribution can easily lead to problems such as material flow interruption and large fluctuations in conveying volume during the conveying process, making it impossible to form a stable material transmission flow. In addition, large-diameter particles may hinder the propulsion of the spiral blades, further affecting the continuity of conveying and resulting in poor conveying stability, making it difficult to meet the needs of continuous and large-scale conveying.

[0045] Figure 14(The rotation direction of the 5th shaft is the same as its rotation direction): The continuous and dense particle flow and the better particle flowability ensure the continuity of the conveying process, the small fluctuation range of the conveying volume, and the ability to maintain a stable transmission state, effectively avoiding the risk of flow interruption; at the same time, the uniform particle distribution makes the spiral blade more evenly stressed, reducing vibration interference during equipment operation and further improving the conveying stability.

[0046] (3) Material utilization rate Figure 13 (The rotation direction of shaft 5 is opposite to its rotation direction): Due to insufficient grinding fineness (the particles are too coarse) and dispersion and retention during the conveying process, some materials fail to fully participate in the subsequent conveying process, resulting in low material utilization and potentially insufficient subsequent process treatment.

[0047] Figure 14 (The rotation direction of the 5th shaft is the same as its own rotation): The finer crushed particles and the efficient and stable conveying effect enable most materials to be transported to the target position intact, significantly improving the effective utilization rate of materials and providing a guarantee for the smooth implementation of subsequent processes.

[0048] Under the unified operating conditions set in this simulation, the matching relationship between the revolution and rotation directions of shaft 5 is a key factor affecting the overall technical effect of the conveying process. It not only affects the conveying efficiency and stability, but also has a significant impact on the degree of fineness of crushing and the material utilization rate. When the revolution and rotation directions of shaft 5 are the same, the interaction strength between the material and the spiral cutting blade 2 and the biomimetic toothed spiral blade 3 can be increased, achieving a better fine crushing effect. At the same time, it promotes particle aggregation to form a stable material flow, significantly improving the conveying efficiency, stability and material utilization rate, resulting in a better overall technical effect. However, when the revolution and rotation directions of shaft 5 are opposite, the particle dispersion is strong and the fineness of crushing is insufficient, resulting in low conveying efficiency, poor stability and poor material utilization rate, leading to a poor overall technical effect.

[0049] The comparison results provide key technical references for optimizing the motion parameters of crushing and conveying devices. In the design and process debugging of crushing and conveying equipment for similar materials (such as biomimetic biological tissue fragments, brittle powders, etc.), it is preferable to adopt parameter settings with the same direction of revolution and rotation, which can effectively improve the overall crushing and conveying performance of the equipment and provide technical support for industrial applications.

[0050] Example 4: As an alternative to Embodiment 3, the circumferential gear 8 and the co-rotating gear 9 are located on one side of the planetary gear set. The rotating shaft 5 rotates through the planetary gear 64 and is coaxially connected to the circumferential gear 8. The co-rotating gear 9 is fixedly located among the multiple circumferential gears 8 and meshes with the circumferential gear 8 for transmission, so that the circumferential gear 8 revolves and rotates in the same direction on the co-rotating gear 9 under the drive of the sun gear 63, thereby realizing that the spiral cutting blade 2, the bionic toothed spiral blade 3, and the bionic finned spiral blade 4 rotate in the same direction when they revolve and when they rotate. In this embodiment, the co-rotating gear 9 is a ring gear structure and is fixed on the sealing cover 73 of the housing 1. The rotating shaft 5, which is rotatably mounted on the planetary gear 64, meshes with the co-rotating gear 9 through the circumferential gear 8. Under the drive of the sun gear 63, the planetary gear 64 drives the rotating shaft 5 to revolve around the sun gear 63. This allows the circumferential gear 8 to revolve around the co-rotating gear 9 while simultaneously rotating in the same direction, so that the spiral cutting blade 2, the bionic toothed spiral blade 3, and the bionic finned spiral blade 4 have the same rotation direction when they revolve and when they rotate.

[0051] Specifically, the diameter of the circumferential gear 8 is smaller than that of the co-rotating gear 9. Compared with the method in Embodiment 3 where the rotation and revolution of the shaft 5 are opposite, the rotation speed of the shaft 5 is higher while the revolution speed is the same.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
