Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and more specifically, to a rotary shearing type mica pulp homogenizing device. Background Technology

[0002] In the production process of mica paper, the existing mica paper pulp homogenization equipment mainly includes high shear homogenizers, double planetary mixers, paddle mixers, hydraulic pulpers and high pressure homogenizers. Their core working principle is to drive the rotor or mixing paddle to rotate by a motor, and use mechanical shearing, hydraulic impact and centrifugal action to break up the agglomerated particles in the mica pulp, so as to achieve uniform mixing of mica particles and water.

[0003] Because mica has a layered crystal structure and its density is much higher than that of water, mica particles tend to agglomerate in unhomogenized mica slurry. If used directly in papermaking, this can lead to problems such as uneven thickness, insufficient mechanical strength, and unstable insulation properties in the finished mica paper. Therefore, it is necessary to homogenize and stir the mica particles to ensure they are evenly dispersed in the slurry, while also maintaining the aspect ratio of the mica sheets, thus laying the foundation for the subsequent production of high-quality mica paper.

[0004] However, in the process of treating mica pulp, existing rotary shear homogenizers are prone to stratification (thinner at the top and thicker at the bottom) during agitation because mica has a much higher density than water. Traditional single-shaft agitation structures tend to form a low-velocity zone in the center, causing mica particles to settle and deposit. Furthermore, the flat blades equipped with these devices have low shearing efficiency for layered mica, which can easily cause swirling phenomena, further aggravating mica deposition and reducing the pulp homogenization effect. This makes it difficult to meet the requirements for pulp uniformity in mica paper production.

[0005] Therefore, there is an urgent need for a rotary shearing mica pulp homogenization device to solve the above problems. Summary of the Invention

[0006] This invention provides a rotary shearing mica pulp homogenizing device. It utilizes blades mounted on the outer wall of a rotating rod, slidably connected to a bottom-shoveling assembly. This assembly, in conjunction with a bottom block at the top of a base plate, forms an undulating structure. As the rotating rod rotates, the bottom-shoveling assembly slides along the surface of the bottom block, generating a reciprocating motion that agitates the deposited mica pulp. Simultaneously, the rotating blades above strike the upward-moving pulp, creating vortices and axial thrust, pushing the pulp into an upward-mixing, rotating state. This solves the problems mentioned in the background art, namely:

[0007] The density of mica is much higher than that of water, which causes a layering phenomenon of thinner top and thicker bottom during stirring. Traditional single-axis stirring creates a low-velocity zone in the center, and the straight blades have low shearing efficiency and are prone to swirling, which aggravates mica deposition and results in poor homogenization.

[0008] To achieve the above objectives, the rotary shearing mica pulp homogenizing device includes a tank, a tank bottom disposed at the bottom of the tank, and a bottom plate disposed inside the tank bottom. A mixing device is disposed between the tank and the bottom plate. The mixing device includes a rotating rod, with multiple blades fixedly connected to the outer wall of the rotating rod, and a bottom shovel assembly slidably connected to the outer wall of the rotating rod near the bottom.

[0009] The top of the base plate is fixedly connected to multiple base blocks, and the surfaces of the multiple base blocks together with the base plate form an undulating structure, which is used to guide the mica pulp and collect it at the top of the base plate between the gaps of the multiple base blocks.

[0010] The bottom-shoveling assembly slides in contact with the surface of the bottom block as it rotates with the rotating rod, and through the drive of the undulating structure, it generates a reciprocating motion force relative to the rotating rod to shovel and disturb the mica pulp deposited on the bottom plate, especially in the gaps between the bottom blocks.

[0011] When the mica pulp moves upward from the bottom under the action of the bottom-shovel assembly, it is struck by multiple rotating blades located above the bottom-shovel assembly, forming an upward vortex and axial thrust, which is used to propel the mica pulp into an upward mixing and rotating state in the tank.

[0012] In the above technical solution, because mica has a much higher density than water, traditional stirring is prone to stratification and sedimentation. However, this device sets up a bottom block on the top of the bottom plate to form an undulating structure with the bottom plate, which can guide the mica slurry to flow and gather at the bottom plate between the bottom blocks, avoiding the slurry from sedimenting in the low flow velocity zone in the center. Furthermore, because the bottom shovel assembly is slidably connected to the rotating rod near the bottom, it slides along the arc-shaped top surface of the bottom block as the rotating rod rotates. Driven by the undulating structure, it generates up-and-down reciprocating motion. This design allows the shovel blades of the bottom shovel assembly to repeatedly cut into the sedimented slurry on the bottom plate, forcefully shoveling and disturbing the sedimented mica particles, causing them to detach from the bottom plate and move upward.

[0013] Meanwhile, because the multiple blades fixed on the outer wall of the rotating rod are inclined and located above the bottom shovel assembly, when the shoveled pulp moves upward, it will be struck by the rotating blades that follow closely behind. In conjunction with the arc-shaped curved plate at the bottom of the blades, an upward vortex and axial thrust can be formed, which pushes the pulp into an upward mixing and rotating state in the tank. This breaks the swirling drawback of traditional stirring, reduces the settling of mica particles, and ensures the pulp quality of mica paper production.

[0014] Specifically, a support rod is coaxially fixedly connected to the bottom of the rotating rod, and multiple sliding grooves are provided axially on the outer peripheral wall of the support rod. The shovel bottom assembly is movably sleeved on the outer periphery of the support rod and slides in cooperation with the sliding grooves.

[0015] Based on this, the bottom shovel assembly includes a sleeve rod, which is movably sleeved on the outer wall of the support rod. Multiple sliders are fixedly connected to the inner wall of the sleeve rod, and the sliders are slidably disposed in the groove of the support rod. Multiple shovel blades are fixedly connected to the outer peripheral wall of the sleeve rod.

[0016] Preferably, the slider is made of high-density metal material to increase the overall counterweight of the bottom shovel assembly.

[0017] The shovel blade is fixedly connected to the outer wall of the sleeve in an inclined shape, and the bottom end of the shovel blade is formed into a sharp angle for cutting into the deposited slurry.

[0018] Preferably, the top surface of the bottom block is an arc-shaped contour surface, and the bottom shovel assembly slides along the arc-shaped contour surface during the rotation of the rotating rod, so that the bottom shovel assembly rotates and reciprocates up and down to cut into the deposited slurry.

[0019] Furthermore, the number of the base block, the shovel blade, and the blade are equal and they are evenly distributed in a circumferential array, and the bottom end of the shovel blade is in sliding contact with the top surface of the base block.

[0020] Along the rotation direction of the rotating rod, each blade is located circumferentially behind the corresponding shovel blade below it, so that the slurry lifted by the shovel blade can be caught and struck by the blade that follows immediately.

[0021] In this technical solution, the blade is fixedly connected to the outer wall of the rotating rod at an incline, and the bottom end of the blade is provided with an arc-shaped curved plate for receiving and guiding the slurry to move upward.

[0022] Based on this, a discharge port is provided at the center of the base plate and at the intervals between the multiple base blocks. Each discharge port is equipped with a control valve to control the timing and amount of discharge. During the homogenization process, the valve is closed to ensure that the slurry in the tank is sealed and fully mixed, and to avoid slurry leakage or diversion that may affect the homogenization effect. After homogenization is completed, the valve is opened to allow the mica slurry accumulated at the bottom of the tank to be discharged quickly and smoothly.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The bottom block on the bottom plate forms an undulating structure with the bottom plate, and the bottom shovel assembly is slidably connected to the rotating rod. When the bottom shovel assembly rotates with the rotating rod, it slides along the arc-shaped top surface of the bottom block and generates up-and-down reciprocating motion, directly shoveling and disturbing the mica particles deposited on the top of the bottom plate in the tank bottom.

[0025] In this process, by setting the bottom block, shovel blade, and blade to be of equal number and evenly distributed in the circumference, and by positioning the blade behind the corresponding shovel blade in the circumference, the slurry lifted by the shovel blade can be caught by the blade and rotated to strike, forming an upward vortex and axial thrust, thereby improving the sedimentation and stratification phenomenon of mica slurry that is thinner at the top and thicker at the bottom.

[0042] 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.

[0043] Currently, the density of mica is much higher than that of water, which easily causes pulp stratification. Traditional single-axis agitators suffer from low flow velocity in the central zone, inefficient shearing by the flat blades (15mm), and swirling phenomena, which exacerbate mica deposition and reduce homogenization efficiency. This invention provides a rotary shearing mica pulp homogenizing device. (See [link to relevant documentation]). Figures 1-2 As shown, it includes a tank body 1, a tank bottom 11 disposed at the bottom of the tank body 1, and a bottom plate 110 disposed inside the tank bottom 11. Multiple bottom blocks 12 are fixedly connected to the top of the bottom plate 110, and the surfaces of the multiple bottom blocks 12 and the bottom plate 110 together form an undulating structure.

[0044] like Figure 3 As shown, a mixing device 13 is provided between the tank body 1 and the bottom plate 110. The mixing device 13 includes a rotating rod 130. Multiple blades 15 are fixedly connected to the outer wall of the rotating rod 130. The mixing device 13 between the tank body 1 and the bottom plate 110 transmits power through the rotating rod 130. An axial groove is provided on the outer periphery of the support rod 1301 that is coaxially fixed at the bottom of the rotating rod 130. The sleeve rod 140 of the bottom shovel assembly 14 is movably sleeved on the support rod 1301.

[0045] For details, see Figure 4 As shown, the bottom shovel assembly 14 includes a sleeve rod 140, which is movably sleeved on the outer wall of the support rod 1301. Multiple sliders 141 are fixedly connected to the inner wall of the sleeve rod 140. The sliders 141 slide in cooperation with the groove, thereby realizing the linkage between the bottom shovel assembly 14 and the rotating rod 130. When the rotating rod 130 rotates, the bottom shovel assembly 14 rotates synchronously. The shovel blades 142 on its outer periphery slide along the arc-shaped top surface of the bottom block 12, and generate up-and-down reciprocating motion under the drive of the undulating structure, directly shoveling and disturbing the mica particles deposited on the bottom of the tank 11.

[0046] See Figure 5 As shown, when the mica pulp moves upward from the bottom under the action of the bottom shovel assembly 14, it is struck by multiple blades 15 located above the bottom shovel assembly 14, forming an upward vortex and axial thrust, which is used to push the mica pulp in the tank 1 to form an upward mixing and rotating state.

[0047] The slider 141 is made of high-density metal material. Based on the characteristics of high-density metal material, such as high density, heavy weight and strong inertia, the slider 141 is made of this material, which can increase the overall counterweight of the bottom shovel assembly 14. This allows the bottom shovel assembly 14 to obtain stronger downward pressure and motion stability during the rotation and reciprocating motion with the rotating rod 130. It ensures that the shovel blade 142 is always in close contact with the arc-shaped top surface of the bottom block 12, and avoids the shovel blade 142 from detaching from the bottom block 12 due to slurry resistance or motion inertia, thus preventing it from effectively cutting into the deposited slurry. This ensures the shovel bottom assembly 14's shoveling and disturbance effect on the mica particles deposited at the bottom of the tank 11.

[0048] like Figure 6As shown, the shovel blade 142 is fixed to the outer wall of the sleeve rod 140 in an inclined shape, and the bottom end is set as a sharp corner. When the shovel bottom assembly 14 rotates, the inclined structure generates an upward thrust, which lifts the shoveled deposited slurry upward. At the same time, the sharp corner reduces the contact area with the deposited slurry and increases the cutting pressure, which pierces and cuts into the mica deposit layer, thereby improving the shoveling efficiency of the mica particles deposited on the surface of the bottom plate 110 in the tank bottom 11.

[0049] Because the top surface of the base block 12 is designed as an arc-shaped contour surface, and multiple base blocks 12 together with the base plate 110 form an undulating structure, the arc-shaped contour surface makes line contact with the shovel blade 142 rather than surface contact compared to a planar structure. The contact area is greatly reduced. According to the friction calculation formula, under the same pressure, the smaller the contact area, the smaller the friction, thus effectively reducing the frictional resistance when the shovel blade 142 slides. At the same time, the arc-shaped structure has good guiding properties. When the shovel blade 142 rotates with the rotating rod 130, it slides smoothly along the arc-shaped surface, which can buffer the impact force between the shovel blade 142 and the base block 12, avoid the two forming a rigid hard contact, reduce the stress concentration at the moment of contact, and prevent the shovel blade 142 and the base block 12 from wearing, deforming or even being damaged due to long-term rigid friction, thereby extending their service life and ensuring the long-term stable operation of the shovel bottom assembly 14.

[0050] The undulating structure formed by the bottom block 12 and the bottom plate 110 changes the original flat planar shape of the tank bottom 11. When the mica pulp settles to the tank bottom 11 due to its high density, the pulp will flow along the slope of the bottom block 12 under the action of gravity. It cannot spread randomly on a single plane and is thus guided and gathered in the gap area between the bottom blocks 12. At the same time, the undulating structure can break the low flow rate zone in the center formed by traditional flat bottom mixing, forcing the pulp to form a directional flow trend between the convex and concave areas of the bottom block 12. This not only avoids excessive deposition of pulp in local areas of the tank bottom 11, but also achieves the guidance and gathering of pulp in the tank bottom 11. At the same time, it provides trajectory support for the up and down movement of the bottom scooping component 14. The undulating structure drives the bottom scooping component 14 to generate up and down reciprocating motion to scoop and disturb the mica pulp deposited on the bottom plate 110, especially in the gap area of ​​the bottom block 12.

[0051] See Figure 7 As shown, since the number of the base block 12, the shovel blade 142 and the blade 15 are equal and they are evenly distributed in a circumferential array, each shovel blade 142 can correspond to a base block 12 and each blade 15 can correspond to a linkage unit of the shovel blade 142. When the rotating rod 130 rotates, each linkage unit works synchronously. The shovel blade 142 slides along the corresponding base block 12 and the blade 15 receives the slurry raised by the corresponding shovel blade 142, avoiding the situation where the shovel blade 142 has no corresponding base block 12 for support and the blade 15 has no corresponding shovel blade 142 for feeding, thus achieving uniform transmission of power and motion.

[0052] When the shovel blade 142 rotates with the rotating rod 130 and lifts the slurry deposited at the bottom of the tank 11 upwards, each blade 15 is located behind the corresponding shovel blade 142 in the circumferential direction along the rotation direction of the rotating rod 130. The blades 15 and shovel blades 142 rotate synchronously. The slurry lifted by the shovel blades 142 will move directly to the action area of ​​the blades 15 under the action of inertia, avoiding the slurry from scattering or falling back to the bottom of the tank 11, ensuring that every piece of shoveled slurry can be accurately received by the blades 15. At the same time, this arrangement can shorten the path of the slurry from being shoveled to being sheared, reduce energy loss, and enable the blades 15 to rotate and strike the lifted slurry in time, breaking the agglomeration of mica particles, preventing the slurry from redepositing during the fall process, and ensuring the continuity of the homogenization effect.

[0053] like Figure 8 As shown, the blade 15 is obliquely fixed to the outer wall of the rotating rod 130, which is used to generate an axial thrust obliquely upward when rotating, pushing the slurry upward and breaking the stratification phenomenon of thinner upper and thicker lower parts; at the same time, the bottom of the blade 15 is provided with an arc-shaped curved plate 150, which is used to increase the contact area with the slurry, improve the receiving range of the slurry lifted by the shovel blade 142, and prevent the slurry from slipping off the edge of the blade 15; and the arc-shaped structure has good flow guiding properties, which can guide the received slurry to flow upward along the curved plate 150 to form a continuous upward vortex.

[0054] For implementation, see Figure 9 As shown, the bottom block 12, the shovel blade 142, and the blade 15 work together to form a guided cyclical workflow from flow concentration to shovel-like disturbance. Specifically, firstly, the bottom block 12 and the bottom plate 110 form an undulating structure. Through the arc-shaped top surface and array distribution, the slurry at the bottom of the tank 11 is guided and concentrated in the gap of the bottom block 12, while providing sliding support and a movement trajectory for the shovel blade 142, driving the bottom shovel assembly 14 to rotate with the rotating rod 130 to generate up-and-down reciprocating motion. Secondly, the shovel blade 142, under the counterweight of the slider 141, and... The bottom block 12 fits tightly, and the inclined, pointed blades 142 efficiently cut into the deposited slurry, lifting it upwards. The array of blades 142 ensures that the slurry in the circumference can be scooped up synchronously. Finally, the inclined blades 15, which are aligned with the blades 142 and located on the rear side, accurately receive the lifted slurry through the arc-shaped curved plate 150 at the bottom. During the rotation, the blades shear and strike the slurry, while forming an upward vortex and axial thrust, which pushes the slurry upward to circulate and prevents mica particles from settling, thus achieving uniform mixing of the slurry in the tank.

[0055] In this embodiment, as Figure 7 As shown, a discharge port is provided at the center of the base plate 110 and at the intervals between the multiple base blocks 12, and each discharge port is equipped with a control valve.

[0056] During the homogenization stage, the control valve is closed, and the discharge port is completely blocked, forming a closed mixing space at the bottom of the tank 11. This state can prevent the slurry in the tank from leaking through the discharge port during the mixing process, ensuring that the slurry is entirely within the action range of the bottom block 12, the shovel 142, and the blades 15. This ensures that the bottom shovel assembly 14 fully disturbs the slurry deposited at the bottom of the tank 11, and that the blades 15 efficiently shear and mix the slurry, preventing a decrease in homogenization effect due to slurry diversion.

[0057] During the discharge stage, once the slurry has been homogenized, the control valve is opened. Since the discharge port is located at the center of the bottom plate 110 and in the gap between the bottom blocks 12, these areas are the main accumulation points of the slurry at the bottom of the tank 11. After opening the valve, the homogenized slurry can be discharged quickly and smoothly under gravity, preventing slurry residue at the bottom of the tank 11. At the same time, during the equipment cleaning stage, after opening the valve, operations such as rinsing with clean water can be used to thoroughly discharge the slurry and impurities remaining at the bottom of the tank 11 through the discharge port, reducing the risk of scaling at the bottom of the tank 11 and improving the equipment's maintenance convenience and reuse efficiency.

[0058] Working principle:

[0059] First, because the density of mica slurry is much higher than that of water, it settles to the bottom of the tank 11. The undulating structure formed by the bottom block 12 on the bottom plate 110 and the bottom plate 110 together changes the flat shape of the bottom of the tank 11, forcing the slurry to flow along the slope of the bottom block 12, guiding and gathering in the area of ​​the bottom plate 110 between the bottom block 12, breaking the low flow velocity zone in the center formed by traditional flat bottom mixing, and avoiding excessive deposition of slurry in local areas.

[0060] Next, when the rotating rod 130 rotates, it drives the bottom shovel assembly 14 to rotate synchronously. The shovel blade 142 of the bottom shovel assembly 14 slides along the arc-shaped top surface of the bottom block 12 and generates up-and-down reciprocating motion under the drive of the undulating structure. The counterweight of the bottom shovel assembly 14 is increased by the high-density metal slider 141 to ensure that the shovel blade 142 is in close contact with the bottom block 12. Its pointed bottom end can efficiently cut into the deposited slurry layer. The inclined structure generates an upward thrust when rotating, directly shoveling and disturbing the mica particles deposited at the bottom of the tank 11 and lifting them upward.

[0061] Subsequently, thanks to the design that the number of bottom blocks 12, shovels 142 and blades 15 are equal and evenly distributed in the circumference, along the rotation direction of the rotating rod 130, the blades 15 are located behind the corresponding shovels 142. The slurry lifted by the shovels 142 directly enters the action area of ​​the blades 15 under the action of inertia. The inclined blades 15 rotate and strike the slurry. The arc-shaped curved plate 150 at the bottom of the blades 15 increases the bearing area and guides the slurry to flow upward. The two work together to form an upward vortex and axial thrust, which pushes the slurry into an upward mixed rotational form in the tank 1.

[0062] Based on this, the upward vortex formed by the blade 15 breaks the stratified state of the slurry, which is thinner at the top and thicker at the bottom, and drives the upper and lower layers of slurry in the tank to mix fully. The mica particles that are not completely dispersed settle back to the bottom of the tank 11 under the action of gravity, and are then scooped up and lifted again by the bottom scooping component 14 to enter the next cycle, so as to achieve continuous and uniform mixing of the slurry in the tank.

[0063] In addition, the control valve at the discharge port is closed throughout the homogenization stage to ensure that the bottom of the tank 11 is sealed and to prevent slurry leakage from affecting the homogenization effect. After the slurry is homogenized, the control valve is opened and the slurry that has accumulated in the center of the bottom plate 110 and the gap between the bottom blocks 12 is quickly discharged under the action of gravity. When cleaning the equipment, the valve is opened and flushing is carried out to thoroughly remove the residual slurry and impurities in the bottom of the tank 11, which is convenient for equipment maintenance and reuse.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
