Description

Technical Field

[0001] The present invention relates to the technical field of fiber cement board production equipment, and specifically relates to an anti-flocculation homogenizing mechanism for a fiber cement slurry refiner. Background Art

[0002] Fiber cement boards (including similar boards such as calcium silicate boards) are building boards made with cement as the cementitious matrix and cellulose fibers as the reinforcing phase, produced through processes such as batching, pulping, forming, and autoclave curing. In the pulping process, wood pulp fibers are first beaten and fibrillated in a refiner to bring the fibers to a suitable length and softness; the refined fibers are then mixed with cement, quartz powder, water and a small amount of additives to form a fiber cement slurry, which is then sent to the forming process. Whether the fibers in the slurry are uniformly dispersed and whether flocs exist directly affect the thickness consistency, surface smoothness and mechanical properties of the formed board.

[0003] Currently, the homogenizing mechanisms matched to the rear end of refiners in the industry generally adopt a conventional single-shaft stirring paddle structure, which relies on the rotation of the stirring paddle to drive the slurry to form an overall circulation to achieve material mixing. Such traditional homogenizing structures have a single overall flow field design, which can only achieve macroscopic overall mixing of the slurry, and cannot adapt to the material characteristics of fiber cement slurry itself, where fibers are prone to tangling and powder materials are prone to flocculation and sedimentation. As a result, the slurry is extremely prone to continuously generating and retaining fiber-cement composite flocs during the homogenization process. This is specifically manifested as defects including low-speed retention zones of slurry inside the equipment, lack of micro-shearing dispersion capacity, and unbalanced disturbance of the full-domain flow field, which ultimately leads to the failure to effectively break and prevent flocs, resulting in poor dispersion uniformity of the discharged slurry. This problem directly causes lumps, uneven thickness, and abnormal local density on the surface of subsequent formed boards, reducing the yield of finished products and product quality stability.

[0004] Therefore, the present invention provides an anti-flocculation homogenizing mechanism for a fiber cement slurry refiner. Summary of the Invention

A main beam frame is fixedly connected to the top of the top cover ring. A mounting base is fixedly installed at the middle position of the main beam frame, and a main drive motor is fixedly installed at the top of the mounting base.

Several static guide baffles are provided on the inner side wall of the uniform material feeding cylinder. Multiple sets of side auxiliary uniform material feeding assemblies are installed around the outer side of the cylinder wall of the uniform material feeding cylinder.

[0007] Preferably, the shearing grid assembly includes an annular frame with a central hole at its center. The annular frame is coaxially fixedly mounted on the main shaft through the central hole, and the outer periphery of the annular frame is alternately and integrally formed with a first shearing tooth and a second shearing tooth.

[0008] Preferably, the bottom guide assembly includes a hub seat and curved guide vanes, with the center of the hub seat protruding upward to form a bushing connection section, which is fixedly connected to the bottom end of the main shaft.

The side drive motor is fixedly installed on the outside of the material leveling cylinder via a connecting seat. The reversing bevel gear transmission pair housing is fixedly installed on the outer wall of the material leveling cylinder. The reversing bevel gear transmission pair housing is provided with a horizontally arranged input bevel gear and two vertically distributed end face bevel teeth on the upper and lower sides of the input bevel gear.

[0010] Preferably, the first shear tooth is bent upward and the second shear tooth is bent downward, and the bent first and second shear teeth interlock to form a micro-shear flow channel for the flow of slurry.

[0011] Preferably, the main circulation blades are provided in at least two sets, and each set of main circulation blades is composed of multiple inclined blades. The inclined blades are arranged at a preset angle with the main shaft axis to push the slurry in the cylinder to form an up-and-down axial circulation flow field.

[0012] Preferably, the curved guide vane is a curved blade structure, and multiple sets of curved guide vanes are evenly arrayed along the circumference between the hub seat and the bushing connection section to disturb the slurry in the dead corner at the bottom of the cylinder.

[0013] Preferably, multiple sets of static flow guide baffles are evenly and obliquely arranged along the inner side wall of the uniform material cylinder to break the low-speed flow field of the cylinder wall boundary layer and balance the overall flow velocity inside the cylinder.

[0015] Preferably, the shearing grid assembly, main circulation blade, bottom guide assembly, and multiple sets of side auxiliary uniform material assembly work together from top to bottom and from inside to outside to form a uniform material flow field without dead angles in the entire area.

[0016] This invention provides a fiber cement slurry grinding mill uniformization mechanism to prevent flocculation. It has the following beneficial effects: 1. This invention features a shear grid assembly that utilizes alternating bending of the first and second shear teeth to form a micro-shear flow channel. The slurry passing through the channel opening generates a gentle fluid micro-shear force, which can break up the fine composite flocs of fiber cement. The blunt-edge structure does not cut long cellulose fibers. Combined with the main circulation blades, it establishes a large circulation flow inside the cylinder, transporting the flocs generated in dead corners to the shear grid for dispersal, thus solving the defect of the lack of micro-shear dispersion capability in traditional mechanisms.

[0017] 2. This invention uses the bottom guide component, the static guide baffle and the side auxiliary uniform material component together to eliminate the dead corners where the slurry stagnates at low speed at the bottom and the wall of the cylinder, reduce the formation of flocs, and balance the flow field disturbance throughout the cylinder. The side auxiliary uniform material component adopts a single motor dual-output bevel gear reversing transmission, which simplifies the equipment structure. Overall, it improves the uniformity of the slurry, reduces defects such as lumps and uneven thickness of the board, and improves the yield of finished products. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: According to Figures 1 to 6 As shown, a fiber cement slurry grinding mill uniform feeding mechanism for preventing flocculation includes a uniform feeding cylinder 21 and a cylinder base 22. The bottom of the uniform feeding cylinder 21 is fixedly connected to the top of the cylinder base 22. A discharge port 23 is provided on one side of the bottom of the uniform feeding cylinder 21. A top cover ring 24 is sealed and installed at the top of the uniform feeding cylinder 21. A main beam frame 25 is fixedly connected to the top of the top cover ring 24. A mounting base 26 is fixedly installed at the middle position of the main beam frame 25, and a main drive is fixedly installed on the top of the mounting base 26. Motor 27; The output end of the main drive motor 27 is fixedly connected to a main shaft 28 that extends vertically into the inner cavity of the uniform material cylinder 21, and a shear grid assembly 30, a main circulating impeller 29, and a bottom guide assembly 31 are sequentially assembled along the main shaft 28 from top to bottom. The end of the main shaft 28 is rotatably connected to the bottom inner wall of the uniform material cylinder 21 through a bearing seat; a number of static guide baffles 40 are inclinedly arranged on the inner side wall of the uniform material cylinder 21; a number of side auxiliary uniform material assemblies 50 are installed around the outer side of the cylinder wall of the uniform material cylinder 21. Based on the embodiments, the following is further obtained: the shearing grid assembly 30 includes an annular frame 301, with a central hole at the center of the annular frame 301. The annular frame 301 is coaxially fixedly mounted on the main shaft 28 through the central hole. The outer periphery of the annular frame 301 is alternately integrally formed with a first shearing tooth 302 and a second shearing tooth 303. The first shearing tooth 302 is bent upward and the second shearing tooth 303 is bent downward. The bent first shearing tooth 302 and the second shearing tooth 303 enclose each other to form a micro-shearing flow channel 304 for the flow of slurry. During the process of the slurry passing through the micro-shearing flow channel 304, it is subjected to the gentle tearing action of the bent tooth edge, generating a micro-shearing effect, and the loose fine flocs are broken up. At the same time, the bent tooth does not produce sharp cutting, avoiding cutting long cellulose fibers. The alternating up and down bending layout can generate shearing areas at different height positions on the outer periphery of the annular frame 301, expanding the micro-shearing action range in the middle of the cylinder. In this embodiment, the shearing grid assembly 30 is arranged in the weak disturbance zone where the circulation converges in the middle of the cylinder. Multiple sets can be arranged. This position is the main area through which fine flocs circulate with the slurry. It adopts an integral molding structure to reduce assembly gaps and avoid material entanglement and fiber wrapping. Preferably, the first shearing tooth 302 bends upward at an angle of 15°-30°, and the second shearing tooth 303 bends downward at an angle of 15°-30°. The groove width of the micro-shearing flow channel 304 is preferably 8-15mm. The bending teeth adopt a blunt edge structure without sharp cutting edges. The purpose is to apply a tearing and dispersing effect only to the fine fiber-cement flocs without cutting the long cellulose fibers that play a reinforcing role, thereby breaking down the micro flocs that drift with the circulation from the material path.

[0022] Based on the embodiment, it is further obtained that: the main circulation blades 29 are provided with at least two sets, each set of main circulation blades 29 includes multiple blades, and the blade plate surface forms an inclined angle with the axis of the main shaft 28, which is used to push the slurry to form an up-and-down circulating flow field; In this embodiment, two or more sets of blades are arranged in layers along the axial direction to enhance the overall axial circulation of the slurry. This carries and transports the flocs generated at the bottom and dead corners of the cylinder to the shear grid assembly for micro-shearing. The blade surface and the axis of the main shaft 28 are preferably inclined at an angle of 30°-45°. This angle balances axial thrust and stirring power consumption. If the angle is too small, the axial circulation will be weak and powder settling will easily occur. If the angle is too large, the stirring resistance and equipment energy consumption will increase significantly. By relying on the inclined blades to form a complete upper and lower circulation loop in the cylinder, the macroscopic mixing of the slurry is achieved, and the flocs are transported at the same time.

[0023] Based on the embodiment, the following is further obtained: the bottom guide assembly 31 includes a hub seat 311 and curved guide blades 313. The center of the hub seat 311 protrudes upward to form a bushing connection section 312. The bushing connection section 312 is fixedly connected to the bottom end of the main shaft 28. The curved guide blades 313 are arranged in an array along the circumferential direction between the hub seat 311 and the bushing connection section 312. The blades are curved blade structures and are used to stir the slurry at the bottom corner of the cylinder to eliminate the low-speed stagnation dead corner at the bottom. In this embodiment, the bottom corner is a high-incidence location for low-speed slurry retention, cement powder settling, and floc formation. The curved guide blades 313 are arranged between the hub seat 311 and the bushing connection section 312, with the blades close to the bottom of the cylinder, directly disturbing the bottom corner area. The curved surface torsion angle of the curved guide blades is preferably 20°-35°, and the number of blades is preferably 4-6 in a circular array. Compared with straight blades, the curved blade structure can generate radial and upward axial thrust at the same time, which not only stirs up the dead corner at the bottom of the cylinder, but also pushes the bottom slurry to flow back upward. Together with the main circulating blades above, a complete circulating flow field is constructed to suppress the formation of flocs at the bottom of the cylinder.

[0024] Based on the embodiment, the following is further obtained: the side auxiliary uniform material assembly 50 includes a side drive motor 501 and a reversing bevel gear transmission pair housing 508. The side drive motor 501 is fixedly installed on the outside of the uniform material cylinder 21 through a connecting seat 502. The reversing bevel gear transmission pair housing 508 is located above the side drive motor 501 and is fixedly installed on the outer wall of the uniform material cylinder 21. The reversing bevel gear transmission pair housing 508 is provided with a horizontally arranged input gear 504 and two vertically distributed end face bevel teeth 505 on the upper and lower sides of the input gear 504. The output shaft of the side drive motor 501 is connected to the input bevel gear 504. The input bevel gear 504 and the end face bevel teeth 505 mesh with each other, and their axes intersect at 90°. Each end face bevel tooth 505 is fixedly connected with a stirring arm 506. The end of the stirring arm 506 extends into the uniform material cylinder 21, and the end of the stirring arm 506 is fixedly connected with a circulating stirring frame 507.

[0025] In this embodiment, a low-velocity boundary layer forms on the inner wall of the cylinder, which is the main source of fine flocs. This structure adopts a single motor input and a double bevel gear 90° reversing transmission. One set of side drive motors 501 can simultaneously drive two sets of circulating stirring frames 507, reducing the number of driving components and lowering the overall cost. The circulating stirring frames 507 rotate close to the inner wall of the cylinder, specifically disturbing the low-velocity slurry at the cylinder wall boundary and breaking the wall retention layer. Multiple sets of side auxiliary material leveling components 50 are preferably evenly distributed along the circumference of the cylinder in 2-4 sets. The gap between the circulating stirring frames 501 and the inner wall of the cylinder is preferably 15-30mm. If the gap is too small, it is easy for material to get stuck and fibers to entangle. If the gap is too large, the disturbance effect on the low-velocity layer on the wall is insufficient, thereby eliminating the low-velocity retention area on the cylinder wall and reducing floc formation.

[0026] During use, the fiber cement slurry processed by the grinding mill is fed into the uniform mixing cylinder 21. The main drive motor 27 starts and drives the main shaft 28 to rotate as a whole. The main shaft 28 synchronously drives the shear grid assembly 30, the main circulating blades 29, and the bottom guide assembly 31 to rotate together. At the same time, the side drive motors 501 of multiple sets of side auxiliary uniform mixing assemblies 50 on the outside of the cylinder work synchronously. The power is transmitted to the upper and lower end bevel gears 505 through the input bevel gear 504. After the bevel gears with 90° intersecting axes reverse transmission, they respectively drive the two stirring arms 506 and the end circulating stirring frame 507 to rotate near the inner wall of the cylinder.

[0027] The main circulation blade 29 is an inclined blade structure. During rotation, it generates both radial and axial thrust on the slurry, creating a large-scale circulation field inside the uniform cylinder 21 that flows from top to bottom and then back up from the bottom. On the one hand, it achieves macroscopic mixing of fiber, cement powder and water, avoiding static settling of inorganic powder. On the other hand, it carries the fine fiber cement flocs that have just been generated in the weak disturbance areas such as the bottom corner and the boundary layer of the cylinder wall into the overall circulation and transports them to the height of the shear grid assembly 30 in the middle of the cylinder.

[0028] The bottom guide assembly 31 rotates with the bottom end of the main shaft 28, and the curved guide blades 313 with curved surface structure on it continuously agitate the bottom of the cylinder and the corner dead zone between the cylinder wall and the bottom. The slurry in this area originally has a low flow rate, cement particles are easy to settle and accumulate, and long fibers are easy to entangle with each other, which is the main source of fine floc formation. When the curved guide blades 313 rotate, they agitate the slurry at the bottom and generate an upward thrust, pushing the bottom deposited material upward into the main circulation, thus inhibiting the growth of flocs at the bottom of the cylinder from the source.

[0029] The static guide baffles 40, which are inclinedly arranged on the inner wall of the uniform material cylinder 21, work together with the circulating stirring frame 507 of the side auxiliary uniform material assembly 50. The circulating stirring frame 507 rotates close to the inner wall of the cylinder, directly disturbing the low-speed boundary layer slurry that is close to the cylinder wall, and destroying the static slurry retention environment near the cylinder wall. After the slurry hits the inclined static guide baffles 40, the flow direction changes, further breaking the local low-speed eddies on the cylinder wall, eliminating the conditions for floc formation at the cylinder wall, and achieving flow field equilibrium in the cylinder wall area.

[0030] When the slurry carrying fine fiber cement composite flocs flows through the shear grid assembly 30, the slurry passes through the micro-shear flow channel 304 formed by the alternating bending and encirclement of the first shear tooth 302 and the second shear tooth 303. The annular frame 301 rotates at high speed with the main shaft, and a speed difference is formed between the shear teeth and the surrounding flowing slurry, generating a gentle fluid micro-shear force at the opening of the micro-shear flow channel 304. The loosely wrapped fiber cement flocs are torn apart under this micro-shear action, achieving floc dispersion. Since the first shear tooth 302 and the second shear tooth 303 adopt a blunt edge bending structure, there are no sharp cutting edges. The shearing force is fluid tearing rather than hard cutting, which can avoid cutting the long cellulose fibers that play a reinforcing role and ensure the mechanical properties of the subsequent finished board. The first shearing tooth 302 bends upward and the second shearing tooth 303 bends downward, so that the micro-shearing flow channel 304 is distributed at different heights on the outer periphery of the annular frame 301, expanding the micro-shearing range and enabling the dispersing of flocculated slurry flowing through this area at different heights in the cylinder.

[0031] After the above-mentioned whole-domain flow field equalization treatment and micro-shear dispersion treatment, the fibers inside the slurry are evenly dispersed, the fiber cement composite flocs are fully broken up, and the qualified slurry is finally output from the outlet 23 on one side of the bottom of the uniform material cylinder 21 to supply the subsequent molding process.

[0032] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
