Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating material production, in particular to a calcium silicate heat-insulating board fiber adding and dispersing device. Background Art

[0002] In the calcium silicate insulation board production industry, fiber addition and dispersion are key processes that determine product performance. Current production lines suffer from the drawbacks of traditional single-shaft agitators: The blind spots created by the single stirring path lead to widespread fiber agglomeration, resulting in a dispersion uniformity of less than 75% for the glass fiber within the calcium silicate matrix. This directly causes fluctuations in the insulation board's flexural strength exceeding ±20%, resulting in a finished product qualification rate of only around 80%. Annual losses due to rework and scrap contribute 12%-15% of production costs.

[0003] While the switch to twin-shaft paddle-type dispersers on some production lines improved fiber dispersion uniformity to 85%, a new problem emerged: material deposits on the walls and bottom of the drum proved difficult to resolve, especially when processing highly viscous raw materials like wood and mineral fibers. Blockages occurred every 6-8 hours. Each cleanup required equipment downtime and disassembly, consuming 1-1.5 hours per batch, impacting annual production capacity by approximately 300,000-500,000 square meters. More seriously, the hardened deposits mixed into the finished product, causing defects such as bubbling and delamination on the board surface. This led to an 18% year-on-year increase in customer returns.

[0004] The industry has attempted to increase the frequency of manual scraping or install spraying devices, but the former increased labor costs by 20%, while the latter affected board forming quality due to improper moisture control, and neither approach fundamentally resolved the problem. The technical bottlenecks of existing equipment have become a key obstacle to the high-quality, continuous production of calcium silicate insulation boards. A new dispersion device is urgently needed to achieve the coordinated optimization of efficient fiber dispersion and anti-clogging feeding. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a calcium silicate insulation board fiber adding and dispersing device to solve the problem that the traditional single-axis stirring device has a stirring blind spot, which easily leads to fiber agglomeration and affects the uniformity of the mechanical properties of the insulation board. Although the dual-axis paddle-type equipment can improve the dispersion effect, the problem of material deposition on the barrel wall and bottom is difficult to solve. Long-term use can easily cause material discharge blockage, resulting in insufficient quality stability of the finished insulation board.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The top of the dispersing mechanism is connected with the up-down knob of the dispersing mechanism, and the bottom of the dispersing mechanism is connected with the up-down knob of the dispersing mechanism, and the bottom of the dispersing mechanism is connected with the up-down knob of the dispersing mechanism.

[0008] Preferably, a servo motor is fixedly mounted on the upper surface of the protective plate, the output shaft of the servo motor is fixedly connected to the left round rod of the two round rods, a group of slots are opened on the inner wall of the dispersion barrel, and the driven gear is movably connected to the group of slots.

[0009] Preferably, an annular groove is provided on the lower surface of the dispersion barrel, the connecting ring is rotatably connected to the annular groove, and two support rods are fixedly connected to the upper surface of the fixed plate, and both support rods are fixedly connected to the protective plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. When the dispersion barrel and the stirring rod rotate in opposite directions, the material undergoes multiple diversion, collision and remixing processes under the action of centrifugal force, shear force and turbulence. The counter-rotating design of the stirring rod and the dispersion rod breaks through the limitations of traditional single-axis mixing. The dynamic relative motion produces a superimposed flow field effect, effectively avoiding the formation of mixing blind spots in the material, significantly improving the dispersion uniformity and dispersion efficiency of the fibers in the matrix, and providing reliable guarantee for the high-quality production of calcium silicate insulation boards.

[0012] 2. After the curved plate completes its upward stroke, it falls back under the action of gravity. During its descent, the inclination angle of the plate body cooperates with the rotating centrifugal force of the dispersion barrel to form a downward pushing force for the material, guiding the material above the curved plate toward the discharge port. Under the dual action of the lifting of the curved plate and the rotation of the stirring rod, the material undergoes a compound movement of vertical conveying and horizontal dispersion, forming a three-dimensional circulating flow field, which significantly enhances the mixing uniformity of the fiber and the matrix material.

[0013] 3. The reciprocating motion of the arc plate also has an anti-blocking function. During the lifting process, a dynamic gap is formed between its edge and the inner wall of the dispersion barrel, which periodically changes the material accumulation form and effectively prevents fiber agglomeration and material deposition. This mechanical structure design converts the rotational motion of the dispersion barrel into multi-dimensional motion of the material, which not only improves the dispersion efficiency, but also ensures the continuity and stability of the feeding system, avoiding uneven mixing or blockage problems caused by material retention.

[0023] The embodiment of the present application provides a calcium silicate insulation board fiber adding and dispersing device, which effectively solves the problem of the traditional single-axis stirring device having a stirring blind spot, which easily leads to fiber agglomeration and affects the uniformity of the mechanical properties of the insulation board. Although the dual-axis paddle type device can improve the dispersion effect, the problem of material deposition on the barrel wall and bottom is difficult to solve. Long-term use can easily cause material discharge blockage, resulting in insufficient quality stability of the finished insulation board. Figures 1 to 7As shown, the overall idea of ​​the technical solution of this application is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a calcium silicate insulation board fiber adding and dispersing device, comprising a frame 1, a feeding rack 5 is provided below the frame 1, a dispersing barrel 6 is rotatably connected in the frame 1, a conical plate 12 is provided below the dispersing barrel 6, a stirring rod 8 is fixedly connected to the upper surface of the conical plate 12, a connecting ring 17 is fixedly connected to the upper surface of the conical plate 12, two pushing rods 16 are fixedly connected to the lower surface of the dispersing barrel 6, two arc plates 18 are provided on the upper surface of the conical plate 12, and the lower surfaces of the two arc plates 18 are fixedly connected to fixed blocks 19. Two groups of dispersion rods 14 are fixedly connected to the inner wall of the bulk barrel 6, a protective plate 2 and a feed port 4 are fixedly connected to the upper surface of the frame 1, a fixed plate 7 is provided below the protective plate 2, a driving gear 11 and a driven gear 20 are provided in the fixed plate 7, the driving gear 11 and the driven gear 20 are meshed with each other, and the upper surfaces of the driving gear 11 and the driven gear 20 are fixedly connected with a round rod 10, the two round rods 10 are respectively rotatably connected to the two fixed plates 7, the driving gear 11 is fixedly connected to the stirring rod 8, and when the device is running, the material falls into the dispersion barrel 6 through the feed port 4, and the servo motor is started. 3. The output shaft of the servo motor 3 is rigidly connected to the driving gear 11. Under the drive of the servo control system, the driving gear 11 rotates at a preset speed. The precise meshing characteristics of the gear pair drive the driven gear 20 on the other side to rotate synchronously. The driving gear 11 is fixed to the stirring rod 8, thereby forming a dynamic rotation center axis of the stirring rod 8. During the rotation process, the stirring rod 8 cooperates with the two groups of dispersion rods 14 fixed inside the dispersion barrel 6 to form a mixing flow field. The driven gear 20 and the inner wall groove 13 of the dispersion barrel 6 form a precisely matched convex tooth structure. Through the gear and the groove 13, the mixing flow field is precisely matched. The limited transmission drives the dispersion barrel 6 to rotate counterclockwise, forming a motion trajectory opposite to the stirring rod 8. When the dispersion barrel 6 and the stirring rod 8 rotate in opposite directions, the material undergoes multiple diversion, collision and remixing processes under the action of centrifugal force, shear force and turbulence. The counter-rotating design of the stirring rod 8 and the dispersion rod 14 breaks through the limitations of traditional single-axis stirring, and produces a superimposed flow field effect through dynamic relative motion, effectively avoiding the formation of a stirring blind spot in the material, significantly improving the dispersion uniformity and dispersion efficiency of the fibers in the matrix, and providing reliable guarantee for the high-quality production of calcium silicate insulation boards.

[0025] A servo motor 3 is fixedly mounted on the upper surface of the protective plate 2. The output shaft of the servo motor 3 is fixedly connected to the round rod 10 on the left of the two round rods 10. A group of card slots 13 are provided on the inner wall of the dispersion barrel 6. The driven gear 20 is movably engaged with the group of card slots 13. An annular groove 15 is provided on the lower surface of the dispersion barrel 6. The connecting ring 17 is rotatably connected to the annular groove 15. Two support rods 9 are fixedly connected to the upper surface of the fixed plate 7. Both support rods 9 are fixedly connected to the protective plate 2. During the rotation of the dispersion barrel 6, the two push rods 16 fixed on its lower surface form a spatial transmission mechanism. When the dispersion barrel 6 rotates along a predetermined trajectory, the push rods 16 perform circular motion synchronously. The fixed block 19 is designed with a wedge-shaped inclined surface, and its inclination angle is optimized by kinematic simulation to ensure that a stable lifting force can be generated when it contacts the push rod 16. During the contact stage between the two, the tangential motion of the push rod 16 is converted into a vertical displacement of the fixed block 19 through the inclined surface, driving the curved plate 18 rigidly connected thereto to perform a linear upward motion along the preset guide track. The limit block set on the surface of the fixed block 19 ensures that its position is fixed during the movement, thereby ensuring the stability of the vertical lifting of the curved plate 18. When the push rod 16 completes a single push stroke, the curved plate 18 and the fixed block 19 are automatically Under the action of its own gravity, it quickly falls back to its initial position, forming a periodic reciprocating motion. In the rising stage, the arc plate 18 produces a material carrying effect by virtue of the rough texture formed by special surface treatment, which lifts the material at the bottom of the dispersion barrel 6 vertically, making it out of the blind spot that is difficult to reach with traditional mixing equipment, and transports it to the strong shearing action area formed by the rotation of the blades of the stirring rod 8 to receive secondary dispersion treatment. When the arc plate 18 completes its rising stroke, it falls back under the action of gravity. During its descent, the inclination angle of the plate body cooperates with the rotating centrifugal force of the dispersion barrel 6 to form a downward material pushing force, which guides the material above the arc plate 18 to the direction of the discharge port. The material is transported to the arc plate 18 and the material is transported to the discharge port. Under the dual action of the lifting of the curved plate 18 and the rotation of the stirring rod 8, it undergoes a composite motion of vertical conveying and horizontal dispersion to form a three-dimensional circulating flow field, which significantly enhances the mixing uniformity of the fibers and the matrix material. In addition, the reciprocating motion of the curved plate 18 also has an anti-blocking function. During the lifting process, a dynamic gap is formed between its edge and the inner wall of the dispersion barrel 6, which periodically changes the material stacking form and effectively prevents fiber agglomeration and material deposition. This mechanical structure design converts the rotational motion of the dispersion barrel 6 into a multi-dimensional motion of the material, which not only improves the dispersion efficiency, but also ensures the continuity and stability of the feeding system, and avoids uneven mixing or blockage problems caused by material retention.

[0036] The driving gear 11 is connected to the output shaft of the servo motor 3, and drives the driven gear 20 to rotate through meshing to transmit power;

[0037] The conical plate 12 is provided below the dispersion barrel 6 and is used to support the stirring rod 8 and the connecting ring 17 and may also play a guiding role for the material;

[0038] The card slot 13 is engaged with the driven gear 20, driving the dispersion barrel 6 to rotate, so that the dispersion barrel 6 and the stirring rod 8 form reverse motion;

[0045] The driven gear 20 meshes with the driving gear 11 and engages with the slot 13 to drive the dispersion barrel 6 to rotate, thereby achieving a reverse motion with the stirring rod 8 .

[0046] Working principle:

[0047] When the device is in operation, the material falls into the dispersion barrel 6 through the feed port 4, the servo motor 3 is started, and the output shaft of the servo motor 3 is rigidly connected to the driving gear 11. Driven by the servo control system, the driving gear 11 rotates at a preset speed, and the precise meshing characteristics of the gear pair drive the driven gear 20 on the other side to rotate synchronously. The driving gear 11 is fixed to the stirring rod 8, so that the stirring rod 8 forms a dynamic rotation center axis. During the rotation process, the stirring rod 8 cooperates with the two groups of dispersion rods 14 fixed inside the dispersion barrel 6 to form a mixing flow field. The driven gear 20 and the inner wall groove 13 of the dispersion barrel 6 form a precisely matched convex tooth structure. The dispersion barrel 6 is driven to rotate counterclockwise through the limited transmission of the gear and the groove 13, forming a motion trajectory opposite to the stirring rod 8. When the dispersion barrel 6 and the stirring rod 8 rotate in opposite directions, the material undergoes multiple diversion, collision and re-mixing processes under the action of centrifugal force, shear force and turbulence. The counter-rotating design of the stirring rod 8 and the dispersion rod 14 breaks through the limitations of traditional single-axis stirring, and produces a superimposed flow field effect through dynamic relative motion, which effectively avoids the formation of a stirring blind spot for the material, significantly improves the dispersion uniformity and dispersion efficiency of the fiber in the matrix, and provides reliable guarantee for the high-quality production of calcium silicate insulation board. During the rotation of the dispersion barrel 6, the two push rods 16 fixed on its lower surface form a spatial transmission mechanism. When the dispersion barrel 6 rotates along a predetermined trajectory, the push rod 16 performs a circular motion synchronously and forms a transmission with the inclined fixed block 19 on the lower surface of the arc plate 18. The fixed block 19 adopts a wedge-shaped inclined surface design. The tilt angle is optimized by kinematic simulation to ensure that a stable lifting force is generated when it contacts the push rod 16. During the contact stage between the two, the tangential motion of the push rod 16 is converted into a vertical displacement of the fixed block 19 through the inclined surface, driving the arc plate 18 rigidly connected thereto to perform a linear upward motion along the preset guide track. The limit block set on the surface of the fixed block 19 ensures that its position is fixed during the movement, thereby ensuring the stability of the vertical lifting of the arc plate 18. When the push rod 16 completes a single push stroke, the arc plate 18 and the fixed block 19 quickly fall back to their initial positions under the action of their own gravity, forming a periodic reciprocating motion. During the rising stage, the arc plate 18 produces a material carrying effect by virtue of the rough texture formed by the special surface treatment, which vertically moves the material at the bottom of the dispersion barrel 6. The material is lifted up and out of the blind spot that is difficult to reach with traditional mixing equipment, and is transported to the strong shearing action area formed by the rotation of the blades of the stirring rod 8 for secondary dispersion treatment. After the arc plate 18 completes its ascending stroke, it falls back under the action of gravity. During its descent, the inclination angle of the plate body cooperates with the rotating centrifugal force of the dispersion barrel 6 to form a downward material pushing force, which guides the material above the arc plate 18 toward the discharge port. Under the dual action of the lifting of the arc plate 18 and the rotation of the stirring rod 8, the material undergoes a composite motion of vertical conveying and horizontal dispersion, forming a three-dimensional circulating flow field, which significantly enhances the mixing uniformity of the fiber and the matrix material. In addition, the reciprocating motion of the arc plate 18 also has an anti-blocking function. During the lifting process, a dynamic gap is formed between its edge and the inner wall of the dispersion barrel 6.The material accumulation form is changed periodically to effectively prevent fiber agglomeration and material sedimentation. This mechanical structure design converts the rotational motion of the dispersion barrel 6 into multi-dimensional motion of the material, which not only improves the dispersion efficiency but also ensures the continuity and stability of the material discharge system, avoiding uneven mixing or blockage caused by material retention.

[0048] Example 1: Economical (suitable for small and medium-sized production lines):

[0049] This embodiment is designed for a production line with a daily output of 2,000-3,000 square meters of calcium silicate insulation boards. The core configuration is as follows:

[0050] Power transmission system: A 7.5kW servo motor 3 (speed adjustable 50-250r / min) is used. The output shaft is rigidly connected to the driving gear 11 (module 2.5, number of teeth 24) through a coupling, and the driven gear 20 (module 2.5, number of teeth 48) is engaged with it to form a 1:2 reduction transmission to ensure stable power transmission.

[0051] Dispersion core structure: The dispersion barrel 6 is a Φ600mm stainless steel cylinder, with two groups of dispersion rods 14 (4 rods in each group, 18mm in diameter) symmetrically welded on the inner wall, and a 25° inclined scraper is set at the end of the rod; the stirring rod 8 has a diameter of 40mm, and a Φ250mm stirring paddle is installed at the end. The gap with the inner wall of the dispersion barrel 6 is controlled at 10-12mm to avoid material retention.

[0052] Anti-blocking and auxiliary components: The curved plate 18 is made of 5mm thick stainless steel plate, the curvature of which matches the inner wall of the dispersion barrel 6. The lower surface fixed block 19 has a bevel angle of 40°, which cooperates with the push rod 16 (diameter 14mm) to achieve a 25mm lifting stroke; the upper surface of the conical plate 12 is polished (roughness Ra ≤ 1.6μm) to reduce material adhesion.

[0053] Support and protection: The frame 1 is welded with No. 10 channel steel, and the fixing plate 7 is connected to two Φ60mm support rods 9 through M12 bolts to ensure that the radial runout of the transmission system is ≤0.15mm; the protective plate 2 is made of 3mm thick steel plate, covering the power transmission components to prevent dust intrusion.

[0054] Operating Results: When servo motor 3 runs at 180 rpm, stirring rod 8 rotates clockwise at 180 rpm, dispersion barrel 6 rotates counterclockwise at 90 rpm, and curved plate 18 reciprocates at a frequency of 25 times / min. Fiber dispersion uniformity reaches 90%, and the machine can operate continuously for 10 hours without clogging. When processing a single batch of 150 kg, energy consumption is 15% lower than that of conventional single-axis equipment, fully meeting the performance requirements of calcium silicate insulation boards for general construction.

[0055] Example 2: High efficiency (suitable for large-scale production lines):

[0056] For a production line with a daily output of more than 5,000 square meters and high requirements for fiber dispersion accuracy, the following optimization is performed based on Example 1:

[0057] Power and transmission upgrade: A 15kW servo motor 3 (adjustable speed 50-350r / min) is used, equipped with a closed-loop control system to achieve precise speed control; the transmission ratio of the driving gear 11 and the driven gear 20 is adjusted to 1:1.5, and the maximum speed of the dispersion barrel 6 is increased to 120r / min, meeting the dispersion requirements of high-viscosity materials.

[0058] Structural optimization:

[0059] The dispersion barrel 6 is expanded to Φ900mm, and spiral guide ribs (lead 400mm) are added to the inner wall to guide the material to form an axial circulation flow; the surface of the dispersion rod 14 is sprayed with tungsten carbide coating, which increases the wear resistance by 2 times and extends the service life to more than 8,000 hours.

[0060] The number of curved plates 18 has increased to 3 groups, and a spring return design has been adopted. The lifting stroke has been expanded to 40mm. The inclined surface of the fixed block 19 is inlaid with a polytetrafluoroethylene wear-resistant layer, which reduces the friction coefficient with the push rod 16 to 0.15.

[0061] A new barrel wall vibration mechanism (frequency 40-60Hz adjustable) is added, which is driven by a micro vibration motor to effectively prevent fibers from adhering to the inner wall of the dispersion barrel 6.

[0062] Intelligent control: The integrated PLC control system monitors the fiber dispersion particle size in real time through the online particle size sensor (detection range 0-500μm). When the particle size exceeds 100μm, the speed of the stirring rod 8 is automatically increased by 10%-15%. The material level sensor is linked to adjust the raising and lowering frequency of the arc plate 18 (20-40 times / min) to adapt to different feed amounts.

[0063] Operational effect: Fiber dispersion uniformity is stable, the blocking failure rate is ≤0.2 times in 24 hours of continuous operation, energy consumption per ton of product is reduced, and the production capacity is increased compared with Example 1. It can meet the stringent requirements of high-end thermal insulation projects for the uniformity of mechanical properties of calcium silicate boards (flexural strength fluctuation ≤±5%).

[0064] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
