Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mixers, in particular to a multi-spiral synergistic coupling type mixer for deep sea mining. BACKGROUND

[0002] One of the core challenges of deep sea mining system is the in-situ pretreatment of the collected materials. Polymetallic nodules often coexist with thick layer of seabed clay, and the material collected by the collection head is a mixture of solid and liquid phases with a very wide particle size distribution, from micron-sized clay particles to centimeter-sized or even larger nodule blocks. The existing pretreatment devices are mostly single-function devices. The commonly used deep sea mining mixers at present mainly include single-spiral mixers and double-spiral stirring mixers, such as the single-spiral static mixer of patent application number CN202120384715.7, which only relies on the pushing and stirring action of a single spiral and lacks targeted crushing structure design; and the double-spiral conical mixer of patent application number CN202222630458.8, which adopts a double-spiral layout but the spiral rotation direction and spacing design does not form a synergistic crushing mechanism. These schemes cannot efficiently and reliably complete the crushing, mixing and conveying integrated operation of deep sea complex materials in a limited space.

[0003] The existing technical solutions have the following significant defects, which seriously restrict the efficiency and environmental adaptability of deep sea mining:

[0004] 1. Inadequate crushing and poor mixing uniformity

[0005] Most of the existing mixers adopt single-spiral or double-spiral structure, relying only on the rotational impact of the spiral blades to achieve crushing, and lack targeted bionic optimization design. It is difficult to completely crush the polymetallic nodules with high hardness and large particles. At the same time, the spiral layout is unreasonable, the residence time of the material in the mixing cavity is short, the crushed minerals and the conveying medium are not uniformly mixed, and the subsequent separation and purification efficiency is affected.

[0006] 2. Low conveying efficiency and serious cavitation phenomenon

[0007] The conveying spiral of the existing mixer is mostly a conventional flat or simple arc structure, lacking turbulence design. When rotating at high speed, it is easy to produce unstable turbulent flow, resulting in large material conveying resistance and low efficiency. At the same time, the cavitation phenomenon caused by turbulent flow will erode the spiral blades, shorten the service life of the mixer and increase the equipment replacement cost. SUMMARY

[0064] 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:

[0065] Example 1:

[0066] like Figures 1 to 7 As shown, the present invention provides a multi-helix cooperative coupling mixer for deep-sea mining, comprising:

[0067] The housing 1 has a feed inlet 11 for feeding and a discharge outlet 12 for discharging.

[0068] The spiral cutting blade 2 is rotatably located at the front of the housing 1 and below the feed inlet 11;

[0069] Bionic tooth spiral blade 3, rotatingly arranged in the front part of the shell 1 and below the feeding port 11;

[0070] Bionic fin spiral blade 4, connected to the end of the spiral cutting blade 2 and the bionic tooth spiral blade 3, and rotatingly arranged in the rear part of the shell 1, so that the crushed material is discharged through the discharge port 12;

[0071] The spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 are configured to rotate synchronously in the shell 1 and form a triangular structure to classify and crush the material entering the shell 1.

[0072] Referring to Figures 1 to 4 , the spiral cutting blade 2 is one, the bionic tooth spiral blade 3 is two, and the bionic fin spiral blade 4 is three, so that the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 form an equilateral triangle structure to rotate synchronously in the shell 1. The bionic tooth spiral blade 3 adopts a double-shaft design, and the two shafts are located on the same horizontal line; the rotating shaft 5 of the spiral cutting blade 2 and the two rotating shafts 5 of the bionic tooth spiral blade 3 form an equilateral triangle layout or an isosceles triangle layout, forming a hybrid system of a three-spiral cooperative crushing structure. The bionic fin spiral blade 4 is located at the end of the hybrid system, has a larger volume and a thinner thickness compared to the first two, and is used for material conveying. The spiral cutting blade 2 is used for secondary fine crushing of the residual large particles after the crushing of the bionic tooth spiral blade 3 through the cutting effect of high-speed rotation, so as to ensure that the mineral particles are uniform in size and meet the requirements of subsequent mixing and conveying.

[0073] Referring to Figure 5 , the outer ring of the bionic tooth spiral blade 3 is uniformly and intervally provided with a crab-eating seal tooth structure 31 in the spiral direction; and the blades of the bionic fin spiral blade 4 are uniformly and intervally provided with multiple groups of fin-shaped protrusions 41 in the spiral direction and on the front and back surfaces of the bionic fin spiral blade 4. The bionic crab-eating seal tooth structure of the bionic tooth spiral blade 3, the double bionic tooth spiral blades 3 are closely arranged and do not intersect with each other, and the bionic crab-eating seal tooth structure 31 is used to preliminarily crush large mineral particles through the extrusion effect during rotation, so as to improve the crushing efficiency and adaptability.

[0074] Referring to Figure 6 , each group of fin-shaped protrusions 41 includes multiple rows of fin-shaped pieces, which are arranged on the front and back surfaces of the bionic fin spiral blade 4 in the axial direction to rotate together with the bionic fin spiral blade 4 to play a flow disturbance role.

[0075] Further, each group of fin-shaped protrusions 41 includes three rows of fin-shaped pieces, which are combined in one piece, two pieces and three pieces, respectively. Alternatively, each group of fin-shaped protrusions 41 can also include two rows of fin-shaped pieces, which are combined in two pieces and three pieces, respectively.

[0076] The fish-like fin-shaped blades of the bionic fin spiral blade 4 are arranged in an array layout of "two in a row and three in a row", or arranged in a decreasing order array layout of "three in a row, two in a row and one in a row"; when rotating at a high speed, the fish-like fin-shaped blades play a spoiler role, inhibit the generation of unstable turbulent flow, reduce the material conveying resistance, and improve the conveying efficiency; at the same time, the spoiler effect can reduce the occurrence of cavitation phenomenon, avoid the erosion of the blades by cavitation, and prolong the service life of the mixing system.

[0077] Further, in addition to the three spiral combination of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4, the spiral cutting blade 2 can be replaced by a bionic shark tooth cutting blade to improve the crushing efficiency through the sharper bionic tooth shape.

[0078] Further, the three spiral combination of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 can be transformed into a four spiral combination, and a square layout is adopted to further optimize the mixing uniformity; the bionic fin spiral blade 4 can be replaced by a bionic whale fin pattern, which can also achieve the effect of spoiler and cavitation prevention.

[0079] The working principle of the embodiment is as follows: the material enters the shell 1 through the feed inlet 11 at the front end of the shell 1, is first crushed and conveyed in the crushing system composed of two bionic tooth spiral blades 3 and one spiral cutting blade 2, is conveyed to the conveying system composed of three bionic fin spiral blades 4 after crushing, and is discharged from the discharge port 12 by the three bionic fin spiral blades 4.

[0080] Embodiment two:

[0081] As another embodiment of the present application, as shown in Figures 7 to 9 A multi-spiral cooperative coupling type mixer for deep sea mining further comprises a driving mechanism 6 for driving the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 to rotate synchronously in the shell 1, the driving mechanism 6 being arranged at one end of the shell 1 to drive the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 to perform reverse revolution and rotation motion in the shell 1.

[0082] The driving mechanism 6 comprises:

[0083] A driving motor 61 is arranged at one end of the shell 1 and is sealed and protected;

[0084] A gear ring 62 is fixedly arranged at one end of the shell 1;

[0085] A sun gear 63 is rotatably arranged at one end of the shell 1 and is connected with the output end of the driving motor 61; further, the output end of the driving motor 61 is transmissionally connected with the sun gear 63 through a speed reducer or a speed variator, and the speed reducer or the speed variator is fixed to the gear ring 62 through an end cover 66;

[0086] The planetary gear 64 is engaged with the sun gear 63 and the ring gear 62, and the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 are coaxially connected with the planetary gear 64 through the rotating shaft 5 respectively.

[0087] The planetary carrier 65 is rotationally arranged on the smooth inner wall of the ring gear 62, and the planetary gear 64 is rotationally arranged on the planetary carrier 65 to realize the rotation of the planetary gear 64 on the planetary carrier 65 while the planetary gear 64 revolves in the ring gear 62. The planetary carrier 65 is a circular structure and is rotationally arranged on the smooth inner wall of the ring gear 62 through a bearing to prevent the material from entering the ring gear 62.

[0088] The driving motor 61 drives the sun gear 63 to rotate to drive the three or four planetary gears 64 to rotate synchronously and revolve synchronously in the ring gear 62, so as to realize the synchronous revolution of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 while the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 rotate.

[0089] Further, the driving mode is not limited to the driving motor 61, and a hydraulic motor can also be used. In addition, an intelligent control system is also included, which dynamically adjusts the rotating speed and direction of each rotating shaft 5 according to the real-time current (torque feedback) of the driving motor 61 to realize adaptive crushing and overload protection.

[0090] Referring to Figure 8 The end of the shell 1 is provided with a limiting mechanism 7 for supporting the synchronous rotation of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4; the limiting mechanism 7 comprises:

[0091] The annular ring 71 is fixedly arranged at the other end of the shell 1.

[0092] The limiting frame 72 is rotationally arranged on the annular ring 71 through a bearing, and the rotating shaft 5 is rotationally arranged on the limiting frame 72.

[0093] The sealing cover 73 is fixedly arranged on the annular ring 71 by bolts.

[0094] By arranging the limiting mechanism 7, the ends of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 rotating synchronously are limited, so that they can stably revolve and rotate in the shell 1.

[0095] The working principle of the embodiment is as follows: the driving motor 61 drives the sun gear 63 to drive the planetary gear 64 to drive the rotating shaft 5 to rotate synchronously, so that the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 arranged on the rotating shaft 5 rotate together; in the process of rotation of the planetary gear 64, the planetary gear 64 moves in the circumferential direction of the sun gear 63 under the action of the ring gear 62 and the planetary carrier 65, so as to drive the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 to revolve in the shell 1, and drive the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 to revolve and rotate synchronously and reversely in the shell 1.

[0096] Embodiment three:

[0097] As another embodiment of the present application, as shown in Figures 10 to 12 A multi-spiral cooperative coupling mixer for deep-sea mining further comprises a circumferential gear 8 and a same-direction gear 9, the circumferential gear 8 is coaxially connected to the end of the rotating shaft 5 and located in the annular ring 71, and the same-direction gear 9 is fixed in the middle of the sealing cover 73 and engaged with the plurality of circumferential gears 8 to drive, so that the circumferential gear 8 revolves and rotates in the same direction on the same-direction gear 9 under the driving of the sun gear 63.

[0098] The driving motor 61 drives the planetary gear 64 to rotate in the ring gear 62 through the sun gear 63, and the rotating shaft 5 connected to the planetary gear 64 moves in the circumferential direction of the shell 1, so that the circumferential gear 8 connected to the end of the rotating shaft 5 rotates in the shell 1 under the meshing action of the fixed same-direction gear 9, and drives the rotating shaft 5 to rotate in the shell 1, and the direction of rotation is the same as the direction of revolution.

[0099] Specifically, referring to Figure 13 and Figure 14 , a standardized crushing and conveying model of the multi-spiral cooperative coupling mixer is constructed based on the Rocky 2024 R1 simulation software, wherein, Figure 13 is a crushing and conveying model simulation cloud diagram when the revolution and rotation directions of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 are opposite, Figure 14 is a crushing and conveying model simulation cloud diagram when the revolution and rotation directions of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 are the same; through comprehensive analysis of the particle size, distribution state and conveying performance of the crushed materials, the following technical effect comparison is made:

[0100] I. Particle distribution comparison

[0101] Figure 13 (Revolution and rotation directions of the rotating shaft 5 are opposite):

[0102] Distribution state: The particles after being crushed by the spiral cutting blade 2 and the bionic tooth spiral blade 3 in the mixing chamber present a significant sparse distribution state, the particle spacing is large and the distribution is uneven, there is no obvious aggregation area, and a continuous particle flow is not formed, part of the particles present a dispersed floating or local retention state, reflecting that the particles lack effective convergence driving force after being crushed.

[0103] Figure 14 (The rotation direction of the rotating shaft 5 is the same as the revolution direction):

[0104] Distribution state: The particles after being crushed by the spiral cutting blade 2 and the bionic tooth spiral blade 3 in the mixing chamber present a significant sparse distribution state, the particle spacing is large and the distribution is uneven, there is no obvious aggregation area, and a continuous particle flow is not formed, part of the particles present a dispersed floating or local retention state, reflecting that the particles lack effective convergence driving force after being crushed.

[0105] II. Comparison of core conveying technology effects

[0106] (1) Conveying efficiency

[0107] Figure 13 (The rotation direction of the rotating shaft 5 is opposite to the revolution direction): Because the particle distribution is sparse and the average particle size is large, the effective conveying channel in the mixing chamber is not fully utilized, the particles are easily affected by their particle size and dispersion state during the conveying process, and diffusion, retention, and even local accumulation phenomena occur, the amount of material advancing along the preset path per unit time is small, the overall conveying efficiency is low, and the conveying effect is weak.

[0108] Figure 14 (The rotation direction of the rotating shaft 5 is the same as the revolution direction): The dense and uniform particle distribution and the finer particle size enable the material to fully fill the conveying channel, the cooperative advancement between particles is enhanced, the invalid diffusion and retention time is reduced, and the flowability of fine particle size particles is better, reducing the conveying resistance, the amount of material conveyed per unit time is significantly improved, the conveying efficiency is significantly improved, and the conveying effect is better. Figure 1

[0109] (2) Conveying stability

[0110] Figure 13 (The rotation direction of the rotating shaft 5 is opposite to the revolution direction): The sparse and uneven particle distribution easily leads to material flow interruption, large conveying amount fluctuation, and other problems during the conveying process, and a stable material transmission flow cannot be formed, and in addition, large particle size particles may hinder the advancement of the spiral blade, further affecting the conveying continuity, the conveying stability is poor, and it is difficult to meet the continuous and large-scale conveying demand.

[0111] Figure 14 ​(Revolute axis 5 public with the same direction of rotation): continuous dense particle flow and better particle flow, to ensure the continuity of the conveying process, small fluctuation range of conveying capacity, can maintain stable transmission state, effectively avoid the risk of flow interruption; at the same time, uniform particle distribution makes the spiral blade force more balanced, reduces the vibration interference in equipment operation, further improves the conveying stability.

[0112] (3) Material utilization rate

[0113] Figure 13 (Revolute axis 5 public with the opposite direction of rotation): due to the lack of crushing refinement (coarse particles) and the existence of dispersion and retention in the conveying process, part of the material cannot fully participate in the subsequent conveying link, and the effective utilization rate of the material is low, which may lead to insufficient subsequent process treatment.

[0114] Figure 14 (Revolute axis 5 public with the same direction of rotation): finer crushed particles and efficient and stable conveying effect enable most of the material to be completely conveyed to the target position, significantly improving the effective utilization rate of the material and providing a guarantee for the smooth development of subsequent processes.

[0115] Under the uniform working conditions set in this simulation, the matching relationship between the revolute axis 5 public and the rotation direction is the key factor affecting the comprehensive technical effect of conveying. It not only affects the conveying efficiency and stability, but also has a significant effect on the crushing refinement degree and material utilization rate. When the revolute axis 5 public and the rotation direction are the same, the effect of the material and the action strength of the spiral cutting blade 2 and the bionic tooth spiral blade 3 can be improved, achieving better crushing refinement effect, promoting particle aggregation to form stable material flow, significantly improving conveying efficiency, stability and material utilization rate, and the comprehensive technical effect is better. When the revolute axis 5 public and the rotation direction are opposite, the particle dispersion is strong, the crushing refinement is insufficient, the conveying efficiency is low, the stability is poor, the material utilization rate is poor, and the comprehensive technical effect is poor.

[0116] The comparison results provide key technical reference for the optimization of the motion parameters of the crushing and conveying device. In the design and process debugging of similar material (such as bionic biological tissue fragments, brittle powder, etc.) crushing and conveying equipment, the parameter setting of the same direction of public and rotation is preferred, which can effectively improve the comprehensive performance of the equipment, and provide technical support for industrial application.

[0117] Example four:

[0118] As an alternative to the third embodiment, the peripheral gears 8 and the same direction gear 9 are arranged on one side of the planetary gear set, the rotating shaft 5 is rotatable through the planetary gear 64 and coaxially connected with the peripheral gears 8, the same direction gear 9 is fixed between the plurality of peripheral gears 8 and engaged with the peripheral gears 8 to drive the peripheral gears 8 to revolve and rotate on the same direction gear 9 under the drive of the sun gear 63, so as to realize the same rotating direction of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 when revolving and rotating. The same direction gear 9 in this embodiment is a ring gear structure and is fixed on the sealing cover 73 of the housing 1, so that the rotating shaft 5 rotatable through the planetary gear 64 is engaged with the same direction gear 9 through the peripheral gears 8, and under the drive of the sun gear 63, the planetary gear 64 drives the rotating shaft 5 to revolve around the sun gear 63, so that the peripheral gears 8 revolve around the same direction gear 9 while rotating in the same direction, so as to realize the same rotating direction of the spiral cutting blade 2, the bionic tooth spiral blade 3 and the bionic fin spiral blade 4 when revolving and rotating.

[0119] Specifically, the diameter of the peripheral gears 8 is smaller than that of the same direction gear 9, and the rotating shaft 5 rotates in the reverse direction of the revolving and rotating mode of the third embodiment, and the rotating speed of the rotating shaft 5 is higher at the same revolving speed.

[0120] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the present application.
