Description

Technical Field

[0001] This application belongs to the field of grouting operation equipment for offshore wind power projects, specifically relating to a fiber dispersion and distribution device for a vertical shaft planetary mixer. Background Technology

[0002] As offshore wind power expands into deeper waters, jacket foundations have become the mainstream choice due to their lightweight structure and high load-bearing capacity. The connection between the jacket foundation and the pile foundation relies on grouting materials for reliable force transmission. In recent years, in addition to focusing on the compressive strength of grouting materials, the tensile strength has also become a key concern. Design units have increased the 28-day tensile strength requirement for grouting materials from none to 7 MPa, and now a requirement of 10 MPa has been proposed. Researchers, drawing on the research ideas of UHPC, have adopted "fiber reinforcement technology," which involves adding a certain proportion (usually 0.5%-2% by volume) of fiber to the grouting material. The fiber's bridging effect inhibits crack propagation. However, during the mixing process, the fibers are prone to agglomeration due to van der Waals forces and hydrogen bonding, forming "fiber clusters." This leads to uneven internal structure of the grouting material, directly affecting the tensile bearing capacity of the connection between the jacket foundation and the pile foundation, and in severe cases, causing structural safety hazards.

[0003] However, existing fiber dispersion techniques have significant drawbacks: Traditional dispersion methods often employ a "mix the grout first, then manually add the fibers" approach. Manual addition easily leads to localized fiber accumulation, making thorough dispersing difficult during subsequent mixing. Mechanical addition, with existing dispersion devices mostly using vibrating screens or rigid mixing teeth, results in fibers either being centrally conveyed or freely scattered onto the grout surface after vibrating screens, leading to localized fiber accumulation similar to manual addition. Rigid mixing teeth only achieve unidirectional axial or radial mixing, causing fibers to easily aggregate along a trajectory within the mixing chamber, resulting in "sufficient local dispersion but uneven overall distribution." Furthermore, the excessive shear force of rigid mixing teeth can break or over-entangle fibers, forming new small agglomerates. After mixing, the dispersed fibers are prone to re-intertwining and agglomerating due to gravity during discharge. The hard collision between the rigid mixing teeth and the fibers can cause fiber deformation or breakage, reducing the bridging reinforcement effect and ultimately affecting the final tensile strength of the grout. Moreover, in offshore construction, existing dispersion devices are often direct transplants of land-based equipment, resulting in large equipment size, inconvenient installation, and poor adaptability.

[0004] Current technologies do not establish a synergistic design between "dispersion uniformity" and "tensile strength of grout." Dispersion devices only aim for "no obvious agglomerates" without considering the spatial uniformity of fiber distribution in the grout. Current technologies cannot simultaneously meet the multiple requirements of "adapting to the characteristics of high-tensile grout materials, uniform fiber dispersion to prevent agglomeration, adaptability to offshore construction, and not damaging grout performance." Therefore, there is an urgent need to develop a fiber dispersion and distribution device for vertical shaft planetary mixers. Summary of the Invention

[0005] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this application is to provide a fiber dispersion and distribution device for a vertical shaft planetary mixer that simultaneously meets the multiple requirements of "adapting to the characteristics of high tensile grouting materials, uniform fiber dispersion and anti-agglomeration, adapting to marine construction, and not damaging the performance of grouting materials".

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: This application discloses a fiber dispersion and distribution device for a vertical shaft planetary mixer, comprising: support frame A fiber dispersion sub-device is mounted on the support frame. The fiber dispersion sub-device is used to perform multi-stage dispersion treatment on fiber materials. A vibration mechanism is also installed on the outer wall of the fiber dispersion sub-device.

[0009] Alternatively, the fabric tray may also be provided with a streamlined dispersion groove.

[0010] Further optionally, it also includes: a cover, which is disposed on the second material cylinder and covers the outer periphery of the fabric tray.

[0011] Further optionally, the cover is a trumpet-shaped structure, and the upper end of the cover is connected to the outside of the second material cylinder, while its lower end is extended outward.

[0012] Further optionally, the fiber dispersion sub-device further includes at least one ring hoop installed on the outer wall of the first feed cylinder, the fiber dispersion sub-device being mounted on the support frame via the ring hoop.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] like Figures 1 to 3 As shown, in one embodiment of this application, a fiber dispersion cloth device for a vertical shaft planetary mixer 400 includes: Support frame 100, A fiber dispersion sub-device 200 is mounted on the support frame 100. The fiber dispersion sub-device 200 is used to perform multi-stage dispersion treatment on fiber materials. A vibration mechanism is also installed on the outer wall of the fiber dispersion sub-device 200. The fiber dispersion sub-device 200 includes: a first feed cylinder 204 and an upper grid 206 and a lower grid 208 arranged sequentially along the fiber material flow direction. The aperture of the upper grid 206 is larger than that of the lower grid 208. This arrangement is used to achieve the grading and screening of fiber materials. The fiber fabric sub-device 300 is also mounted on the support frame 100, and the feeding port 203 of the fiber fabric sub-device 300 is connected to the outlet of the fiber dispersing sub-device 200.

[0020] This embodiment achieves efficient crushing and grading of fibrous materials through the synergistic effect of vibration mechanism excitation and two-stage grids with different apertures. It can simultaneously meet multiple requirements such as "adaptation to the characteristics of high tensile grouting materials, uniform fiber dispersion and anti-agglomeration, compatibility with offshore construction, and no damage to the performance of grouting materials".

[0021] In this embodiment, the support frame 100 is preferably a steel support frame, which serves as the main load-bearing structure. The lower end of the main support rod 101 is fixed to the steel frame foundation of the offshore wind power grouting equipment by welding.

[0022] In one embodiment of this application, such as Figure 4 As shown, the support frame 100 includes: a main support rod 101 and multiple layers of horizontally arranged sub-support structures, all of which are installed on the main support rod 101; Both the fiber dispersion sub-device 200 and the fiber fabric sub-device 300 are mounted on the sub-support structure.

[0023] This embodiment only illustrates the case with a three-layer sub-support structure, namely, three parallel layers of first horizontal brace 102, second horizontal brace 103, and third horizontal brace 104. The first horizontal brace 102 and the second horizontal brace 103 are used to install the fiber dispersion sub-device 200, and the third horizontal brace 104 is used to install the fiber fabric sub-device 300. Furthermore, in this embodiment, a rotating mechanism 110 is provided in the middle of the vertically arranged main support rod 101, enabling the main support rod 101 to rotate around its own axis. This allows one fiber dispersion and distribution device to be switched and shared among multiple mixers 400, and can effectively avoid the ton bag breaking operation area, improving the coordination of the working space and the utilization rate of equipment. Figure 4 As shown, this illustration depicts a configuration with two mixers 400. The rotating mechanism 110 can be specifically implemented by fitting a large thrust bearing onto the middle section of the main support rod 101, and locking it after rotation via a sleeve with a locking pin. This design allows the operator to manually or via a small drive device rotate the upper part of the support frame 100 around its axis, thereby switching the entire working mechanism between two positions (i.e., two mixers 400).

[0024] The fiber dispersion device 200 further includes a feeding port 203 and a discharging port 205 connected vertically, wherein the feeding port 203 and the discharging port 205 are sequentially connected to the upper and lower sides of the first material cylinder 204.

[0025] Furthermore, in this embodiment, the feeding port 203 adopts a trumpet-shaped structure, with a larger diameter at the upper end and a smaller diameter at the lower end, to facilitate the reception of fibrous materials. The aforementioned first material cylinder 204 adopts a cylindrical structure, with both the upper and lower ends being open structures, and its cylinder diameter is adapted to the lower diameter of the trumpet-shaped feeding port 203.

[0026] In this embodiment, schematically, the discharge port 205 adopts a reduced diameter structure, wherein the upper diameter of the reduced diameter structure is larger than its lower diameter, and both its upper and lower ends are open structures without sealing plates, so as to realize the centralized guidance and discharge of fiber materials, and play the role of gathering and guiding fiber materials.

[0027] The vibration mechanism preferably employs a vibration motor 209, which promotes the dispersion of fiber materials through vibration. When the vibration motor 209 is operating, its high-frequency vibration is directly transmitted to the fiber dispersion sub-device 200, causing the fiber material clumps passing through the grid to be broken up and separated.

[0028] like Figure 1 As shown, in this embodiment, the fiber dispersion sub-device 200 further includes at least one ring clamp 201 installed on the outer wall of the first feed cylinder 204, and the fiber dispersion sub-device 200 is installed on the support frame 100 via the ring clamp 201. The specific number of ring clamps 201 is illustrated by two. Specifically, the ring clamps 201 corresponding to the first cross brace 102 and the second cross brace 103 are respectively installed at the cylinder body of the cylindrical first feed cylinder 204 and at the reduced-diameter outlet 205, for fixing the fiber dispersion sub-device 200.

[0029] A vibration isolation pad 202 is also provided between the outer wall of the first material cylinder 204 and the ring 201. The vibration isolation pad 202 is preferably made of rubber. The vibration isolation pad 202 is used to absorb vibration and prevent the vibration generated by the vibration motor 209 from being transmitted to the main support rod 101, thereby ensuring the stability of the fabric distribution device.

[0030] Furthermore, in this embodiment, the upper grid 206 and / or the lower grid 208 are detachably installed inside the first feed cylinder 204. Specifically, the sidewalls of both the upper and lower grids are provided with bolt holes, and the corresponding positions of the first feed cylinder 204 and the reduced-diameter discharge port 205 are provided with matching bolt holes. The positioning and fixing of the upper grid 206 and the lower grid 208 are achieved through bolt connection. Both the upper grid 206 and the lower grid 208 are detachable structures, which can be replaced with grids of different apertures or diameters according to the characteristics of the fiber material, thereby improving the applicability and screening flexibility of the device.

[0031] Specifically, for example, four sets of threaded mounting seats evenly distributed circumferentially are welded to the middle of the inner wall of the first material cylinder 204 and the middle of the inner wall of the reduced-diameter discharge port 205. The upper grid is mounted to the mounting seat in the middle of the first material cylinder 204 by bolts 207; the lower grid is mounted to the mounting seat in the middle of the reduced-diameter discharge port 205 in the same way. Because of the bolt 207 connection, the upper grid and the lower grid 208 are detachable, and users can easily replace them with grids of different apertures or diameters according to the required fiber length and feed rate. In another embodiment, the upper grid is disposed in the middle of the first feed cylinder 204, and the lower grid is disposed in the middle of the reduced-diameter discharge port 205, wherein the aperture of the upper grid is larger than that of the lower grid, so as to achieve grading and screening of fibrous materials. By increasing the distance between the upper grid 206 and the lower grid 208, the grading and screening effect of fibrous materials from coarse to fine can be further improved.

[0032] like Figure 3 As shown, in this embodiment, the fiber fabric sub-device 300 includes: a second material cylinder 305 and a fabric disc 303 driven by a rotating motor. The rotating motor is mounted on the second material cylinder 305 via a support member. The fabric disc 303 is disposed at the lower end of the second material cylinder 305, and the second material cylinder 305 forms an annular discharge gap, thereby forming a discharge port 205 for the fiber material. After the fiber material falls from the fiber dispersing device above, it is thrown out through the annular gap after being rotated by the fabric disc 303. The second material cylinder 305 is suspended above the fabric disc 303.

[0033] The fabric tray 303 has a rotating shaft in the middle, which is connected to a rotating motor to drive the fabric tray 303 to rotate and centrifugally throw out the fiber material.

[0034] In this embodiment, the support member preferably adopts a cross-shaped support structure 306.

[0035] The fabric tray 303 is also provided with streamlined dispersion grooves 304 that are radially distributed, so that the fibers fall evenly in a large-diameter circular trajectory after being centrifuged, which effectively avoids the concentrated accumulation of fibers in the mixer 400 and significantly improves the uniformity of fiber material distribution in the concrete matrix.

[0036] It also includes a cover 307, which is disposed on the second material cylinder 305 and covers the outer periphery of the fabric disc 303. The fiber material ejected by centrifugation impacts the inner wall of the cover 307, achieving secondary crushing of small fiber clumps and limiting the dispersion range of the fiber material, preventing the fiber material from being thrown out of the mixer 400; the falling trajectory of the fiber material is distributed in a large-diameter circle, thereby avoiding the concentrated accumulation of fiber material. Preferably, the upper end of the cover 307 is welded to the outside of the second material cylinder 305, and its lower end expands outward.

[0037] The cover 307 has a trumpet-shaped structure, and the upper end of the cover 307 is connected to the outside of the second material cylinder 305. Its lower end is set outward. The purpose of this setting is twofold: first, to receive the fiber material thrown out by centrifugal force, and the fiber can be broken into secondary parts by hitting the inner wall of the cover 307; second, to effectively limit the splash range of the fiber material and ensure that all fiber material can fall into the mixing chamber of the mixer 400 below.

[0038] In operation, the fiber material is fed into the funnel-shaped inlet 203. Under the vibration of the vibrating motor 209, the fiber material clumps are effectively dispersed and screened as they fall through the upper and lower grids. The dispersed fiber material falls through the narrowed outlet 205 and enters the second feed cylinder 305 of the fiber fabric sub-device 300, landing on the high-speed rotating fabric disc 303. Under centrifugal force, the fiber material is evenly thrown out along the streamlined dispersion trough 304 through the annular gap, impacts the inner wall of the cover 307, and then evenly disperses into the mixer 400 in a large circular trajectory, avoiding concentrated accumulation.

[0039] When it is necessary to feed another mixer 400 or avoid the breaking of ton bags, simply loosen the locking pin of the rotating mechanism 110, rotate the entire device by a certain angle (such as 90° or 180°) and then relock it. The operation is simple and greatly improves the utilization rate of equipment and the flexibility of production line layout.

[0040] This application achieves efficient crushing and grading of fiber materials through the synergistic effect of a vibration mechanism and two levels of grids with different apertures. The combination of a rotatable feeding disc and a streamlined dispersion trough ensures that the fibers, after being centrifugally ejected, fall evenly in a large-diameter circular trajectory, effectively preventing fiber accumulation within the mixer and significantly improving the uniformity of fiber distribution in the concrete matrix. The upper and lower grids in this application are detachably installed with bolt connections, allowing users to easily replace grids with different apertures or diameters according to the type and specifications of the fiber materials used, greatly enhancing the adaptability of the device to different engineering needs and fiber materials. The cover installed on the outside of the fiber feeding sub-device in this application not only performs secondary crushing of the ejected fibers but also reliably limits the fiber dispersion range, preventing fiber materials from splashing out of the machine, ensuring operational safety and improving the working environment. A rotating mechanism is installed in the middle of the vertical main support rod, enabling the entire device to rotate. This design allows a single fiber dispersion fabric distribution unit to be flexibly switched and shared among multiple adjacent mixers, which not only improves the utilization rate of a single fabric distribution unit and reduces equipment costs, but also effectively avoids regional conflicts with surrounding operations such as bag breakage, thus optimizing the production line layout. Therefore, this application has good market application prospects.
