[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] As used herein, phrases such as "in one embodiment", "according to one embodiment", "in some embodiments", etc. generally refer to the fact that the specific features, structures, or characteristics after such phrases can be included in at least one embodiment of the present disclosure. Therefore, the specific features, structures, or characteristics can be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment.

Instead, the use of terms such as "example", "exemplary", etc. is intended to present concepts in a specific manner.

[0043] In the related art, the steps for preparing porous microsphere calcium silicate microspheres by hydrothermal method include: Step 1, sodium silicate solution: Add sodium metasilicate nonahydrate and surfactant into water, stir and mix evenly to obtain an aqueous sodium silicate solution containing surfactant; calcium nitrate solution: Add calcium nitrate tetrahydrate into water, stir and mix evenly to obtain a calcium nitrate solution; Step 2, Add the calcium nitrate solution to the aqueous sodium silicate solution containing surfactant, and continuously stir to finally obtain a stable calcium silicate emulsion; Step 3, Let the calcium silicate emulsion stand for aging; Step 4, Filter and wash the aged product, and obtain porous calcium silicate ceramic powder after drying. In Step 2, in the related art, generally, stirring is used to promote mixing. However, during the stirring process, the mixed solution will gradually change from a diluted state to a viscous state as time increases. The inventor found that due to the fixed inclination angle of the stirring paddle, the generated axial force and radial force are fixed. As the solution gradually becomes viscous (for example, polyacrylamide in the surfactant is a polymer with thickening effect, and as the reaction proceeds and the substances in the system change, it will further cause the solution to become viscous), the axial and radial forces generated by the fixed inclined stirring paddle are difficult to conform to the mixing and stirring of the solution with changing viscosity, thus affecting the final mixing effect of the solution.

[0044] All the defects existing in the above solutions are the results obtained by the inventor through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed in this disclosure by the present disclosure for the above problems should be the contributions made by the inventor to the present disclosure during the process of the present disclosure.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0047] As Figure 1 shown, at least one disclosed embodiment provides a method for preparing porous microsphere calcium silicate by stirring, including: during the process of adding the calcium nitrate solution to the aqueous sodium silicate solution containing surfactant and continuously stirring, the control module is adapted to obtain the inclination angle of the stirring paddle 1 and the solution viscosity in real time, and adjust the inclination angle of the stirring paddle 1 in real time according to the solution viscosity, so that the end face of the stirring paddle 1 that pushes the solution rotates gradually from facing up to facing down, thereby realizing the generation of axial flow with different forces in the solution during the stirring process to promote cyclic mixing, improving the mixing effect, and helping the solution dissipate heat.

[0048] As Figure 2As shown, in this embodiment, during the stirring process, the rotation direction of the stirring shaft 2 is as shown by F2 in Figure 2 , and the rotation direction of the stirring paddle 1 is as shown by F1.

[0049] As Figure 3 shown, in this embodiment, at the beginning of stirring, the viscosity of the solution is not high. At this time, the end face of the solution pushed by the stirring paddle 1 faces upward, that is, obliquely upward. During the stirring process of the solution, an upward axial flow is generated near the stirring shaft 2. At this time, the flow direction of the solution and the particulate matter is as shown by a1 in Figure 3 . When the solution is relatively dilute in the initial stage of the reaction, the upward axial flow is used to extract the solution and particulate matter at the bottom of the tank body 3 and move them upward to promote the mixing reaction and improve the stirring effect of the solution.

[0050] As Figure 5 shown, in this embodiment, after stirring for a certain time, the viscosity of the solution is relatively high. At this time, the end face of the solution pushed by the stirring paddle 1 rotates downward, that is, obliquely downward. During the stirring process of the solution, a downward axial flow is generated near the stirring shaft 2. At this time, the flow direction of the solution and the particulate matter is as shown by a3 in Figure 5 . A flow is formed in the solution to push the heat at the center of the bottom of the tank body 3 toward the tank wall of the tank body 3, which is convenient for the viscous solution to dissipate heat, and can prevent the calcium silicate precursor particles from settling at the bottom of the tank body 3 and improve the mixing effect of the solution.

[0051] In this embodiment, when the solution is relatively viscous, the stirring paddle 1 pushes the solution to flow, and the force of the downward axial flow generated near the stirring shaft 2 is greater than the force of the solution approaching the stirring shaft 2, so that the solution can flow to generate a cycle, which is convenient for dissipating the heat at the bottom of the tank body 3.

[0052] In this embodiment, in the later stage of the reaction when the solution is relatively viscous, the high-viscosity fluid is likely to cause the calcium silicate precursor particles to settle. The axial flow from top to bottom directly flushes the bottom of the tank body 3, and the heat is exported through forced convection. Since the high-viscosity fluid has poor thermal conductivity, the downward flow can prevent the heat from accumulating at the bottom. Since the solution is relatively viscous at this time, if an upward axial flow is still generated, the axial force needs to overcome the viscosity resistance of the solution and the self-weight of the solution, while the sum of the downward axial force and the self-weight of the liquid only needs to overcome the liquid resistance, which can improve the heat dissipation effect.

[0053] In an alternative embodiment, the method for real-time regulating the inclination angle of the stirring paddle 1 according to the viscosity of the solution includes: constructing a relationship model between the inclination angle and the viscosity:

[0054]

[0055] where θ is the inclination angle of the stirring paddle 1, and the inclination angle position of the stirring paddle 1 is as shown in Figure 2 ; θmax is the maximum tilting angle of the stirring paddle 1, i.e., 135°; θ min is the minimum tilting angle of the stirring paddle 1, i.e., 45°; μ is the solution viscosity level, with the unit of Pa·s; μ max is the maximum value of the solution viscosity level; μ min is the minimum value of the solution viscosity level. Before the preparation starts, the preliminary viscosity is measured as μ 初 and the viscosity after the preparation ends is measured as μ 终 The range between these two values is equally divided into 10 parts, which is the viscosity level 1 - 10. The corresponding viscosity number is selected according to the measured implementation viscosity and substituted into the formula for calculation; the control module adjusts the stirring paddle 1 according to the calculated current required tilting angle.

[0056] In this embodiment, as the viscosity increases, the tilting angle of the stirring paddle 1 increases, improving the stirring effect.

[0057] In an alternative embodiment, during the stirring process, the tilting angle of the stirring paddle 1 changes from small to large according to the increase in the solution viscosity. When the tilting angle of the stirring paddle 1 is the smallest, the end face of the stirring paddle 1 that pushes the solution faces upward, and when the tilting angle of the stirring paddle 1 is the largest, the end face of the stirring paddle 1 that pushes the solution faces downward.

[0058] In an alternative embodiment, the stirring paddle 1 rotates with the stirring shaft 2 to stir the solution; the stirring paddle 1 rotates along the circumferential direction of the radial direction of the stirring shaft 2 to adjust the tilting angle of the stirring paddle 1.

[0059] In this embodiment, it is assumed that the minimum viscosity level is 1 and the maximum is 10; since the minimum tilting angle is 45 and the maximum is 135; if the currently measured viscosity level is 5, the tilting angle obtained by substituting into the formula is 85 degrees; through experiments, it is proved that when the tilting angle is greater than 135 degrees (tending to be horizontal), the geometric characteristics of the blade are closer to the radial flow stirring paddle. Such blades push the fluid outward by centrifugal force to form a flow field mainly dominated by radial flow. The shear force generated by the radial flow is relatively large, rather than a non-uniform axial circulation. Therefore, the maximum requirement is 135 degrees. Similarly, when the minimum angle is less than 45 degrees, the angle range is limited to 45 - 135. For the initial stage of stirring, the solution is relatively dilute, and the axial force and radial force generated by the 45-degree stirring shaft are relatively balanced, promoting mixing. As the viscosity increases, the angle gradually increases, and the generated axial force is greater than the radial force, generating an upward thrust to remove air bubbles in the water. By the middle stage of the reaction, when it is relatively viscous, the tilting angle tends to 90 degrees (60 degrees - 90 degrees, 90 degrees - 120 degrees, and the radial force gradually increases and the axial force gradually decreases during this process). For example Figure 4The state shown, at this time the radial force generated is the largest, generating a shearing force to break the particle agglomeration of the formed calcium silicate crystals. As the reaction progresses to the later stage and the solution becomes more viscous, the inclination angle gradually approaches 135 degrees, generating an axial force from top to bottom to dissipate the heat at the bottom of the tank body 3.

[0060] At least one other disclosed embodiment also provides a stirring preparation system for porous microsphere calcium silicate, including: an acquisition module configured to obtain the inclination angle of the stirring paddle 1 and the solution viscosity in real time; a regulation module configured to regulate the inclination angle of the stirring paddle 1 in real time according to the solution viscosity, so that the end face of the stirring paddle 1 pushing the solution rotates gradually from facing up to facing down.

[0061] At least one other disclosed embodiment also provides a computer-readable storage medium, on which a computer program / instructions are stored, and when the computer program / instructions are executed by a processor, the steps of the above-mentioned stirring preparation method for porous microsphere calcium silicate are implemented.

[0062] At least one other disclosed embodiment also provides a computer program product, including a computer program / instructions, and when the computer program / instructions are executed by a processor, the steps of the above-mentioned stirring preparation method for porous microsphere calcium silicate are implemented.

[0063] As Figure 6 shown, at least one other disclosed embodiment also provides a stirring preparation device for porous microsphere calcium silicate, including: a tank body 3, and a stirring mechanism arranged in the tank body 3, the stirring mechanism is electrically connected to a control module, and the control module is configured to stir the solution in the tank body 3 by using the above-mentioned stirring preparation method for porous microsphere calcium silicate.

[0066] In this embodiment, the driving member can be a motor or the like to drive the stirring shaft 2 to rotate at a constant speed.

[0067] In this embodiment, the rotating assembly may be composed of a servo motor and a transmission member, so that after the control module obtains the angle of the stirring paddle 1 at this time, the servo motor is controlled to drive the transmission member to make the stirring paddle 1 rotate precisely, so that the stirring paddle 1 can rotate precisely to the required angle.

[0068] In an alternative embodiment, a viscosity sensor is provided in the tank body 3, and the viscosity sensor is electrically connected to the control module. The viscosity sensor is adapted to detect the viscosity of the solution in the tank body 3 and then send the detected viscosity to the control module; an angle sensor is provided on the stirring paddle 1, and the angle sensor is electrically connected to the control module. The angle sensor is adapted to detect the tilt angle of the stirring paddle 1 and then send the detected tilt angle to the control module.

[0069] In summary, the preparation method of the porous microsphere calcium silicate includes: during the process of adding a calcium nitrate solution to an aqueous sodium silicate solution containing a surfactant and continuously stirring, the control module is adapted to obtain the tilt angle of the stirring paddle 1 and the solution viscosity in real time, and adjust the tilt angle of the stirring paddle 1 in real time according to the solution viscosity, so that the end face of the stirring paddle 1 pushing the solution gradually rotates from facing up to facing down, thereby realizing the generation of axial flows with different forces in the solution during stirring to promote cyclic mixing, improving the mixing effect, and helping the solution dissipate heat.
