Abstract
Description
Technical Field
[0001] This invention belongs to the field of cement mortar production control technology, and relates to a cement mortar production equipment operation data acquisition and management system. Background Technology
[0002] With the continuous development of modern construction engineering technology and the increasing demands for the quality of building materials, the quality control of cement mortar, as a fundamental and crucial building material, has become particularly important. In the traditional cement mortar preparation process, the mixing stage often relies on the experience of operators and manual control. This method is not only inefficient but also makes it difficult to guarantee the stability and consistency of cement mortar quality.
[0003] In the process of cement mortar preparation, the mixing state of various aggregate materials is a key factor affecting the quality of cement mortar, which directly affects the uniformity and strength of cement mortar. Therefore, it is particularly important to monitor and control the mixing process in real time.
[0004] However, the current cement mortar production process has the following limitations: 1. The existing methods for controlling the mixing parameters in the cement mortar mixing and preparation process lack depth. For example, the setting and adjustment of the mixing speed are limited to a certain speed range, without considering the situation where this speed range is not suitable, which leads to the speed adjustment effect not meeting expectations.
[0005] 2. There are often blind spots in the mixing of production equipment. Aggregates in these areas are prone to agglomeration and clumping. However, existing technologies often lack the ability to detect and adjust the agglomeration of aggregates in these blind spots. Instead, they rely more on the experience of operators and experimental data for adjustment, which results in the mixing effect not reaching the optimal state. Summary of the Invention
[0006] In view of this, in order to solve the problems mentioned in the background technology, a data acquisition and management system for cement mortar production equipment operation is proposed.
[0007] The objective of this invention can be achieved through the following technical solution: This invention provides a cement mortar production equipment operation data acquisition and management system. The system includes: an operation parameter presetting module, used to acquire the composition of cement mortar materials in the production equipment and the pre-set mixing speed, and to divide the cement mortar mixing stage into various mixing time periods. During each mixing time period, three-dimensional images of cement mortar in the production equipment are intermittently acquired. Taking the position of each blade in the production equipment as the center, the axial space of each blade is evenly divided, and the corresponding standard deviation stress of blade thrust in the production equipment is identified.
[0008] The cement mortar condition monitoring module is used to analyze the aggregate distribution uniformity index and the aggregate-mortar adhesion index of cement mortar in the production equipment.
[0009] The mixing speed adjustment module is used to retrieve the balanced mixing speed range of cement mortar in the production equipment based on the aggregate distribution uniformity index and the adhesion index between aggregate and mortar in the cement mortar in the production equipment, identify the set adaptability of the preset mixing speed, and determine the suitable mixing speed of cement mortar in the production equipment when the preset mixing speed is not suitable, and make real-time correction.
[0010] The blade angle adjustment module is used to collect the cement mortar mixing resistance in the axial space of each blade in real time by using stress plates installed on each blade component in the production equipment when the preset mixing speed is adapted, and to monitor the stress characteristics of each blade component in the axial space of each blade, thereby determining the blade angle adjustment process.
[0011] The stirring termination determination module is used to determine the stirring stop time by analyzing the uniformity of the force on the blades.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention analyzes the aggregate distribution uniformity index and the adhesion index between aggregate and mortar in the cement mortar in the production equipment, retrieves the equilibrium mixing speed range of cement mortar in the production equipment, and then, by identifying the set adaptability of the preset mixing speed, makes real-time correction to the cement mortar in the production equipment to make the aggregate and mortar fully mixed, avoiding the waste of raw materials due to insufficient mixing. At the same time, a suitable mixing speed can avoid the mixing equipment from operating at high load for a long time while ensuring the quality of cement mortar.
[0013] (2) By detecting the amount of aggregate accumulation in the blind zone of the production equipment, screening the blades with different angles and determining their adjustment angle, this invention helps to reduce the agglomeration and settling of cement mortar in the production equipment, thereby making the cement mortar mixing effect in the production equipment more uniform.
[0014] (3) By detecting the uniformity of the stirring resistance deviation of each blade in the production equipment, the present invention can indirectly reflect the degree of mixing uniformity of the materials in the stirring container. At this time, it is determined that the stirring stops. This method of identifying stirring resistance can directly reflect the mechanical state during the stirring process and has a high degree of directness. Attached Figure Description

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.

[0023] Please see Figure 2 As shown, the mixing speed preset module is used to obtain the composition of cement mortar materials in the production equipment and preset the mixing speed, and divide the cement mortar mixing stage into each mixing time period. During each mixing time period, three-dimensional images of cement mortar in the production equipment are acquired intermittently. Taking the position of each blade in the production equipment as the center, the axial space of each blade is evenly divided, and the standard deviation stress ΔF of the blade thrust in the production equipment is identified.
[0024] The cement mortar material composition includes sand and gravel components of various sizes and water, and sand and gravel components exceeding the preset baseline size are referred to as aggregate particles.
[0025] In a preferred embodiment, the stirring speed preset module includes: obtaining the component amounts W of each material. i The water mass C was determined, and the corresponding preset water absorption κ′ of each material component was extracted. i Calculate the water-cement ratio in the production equipment. The mixing speed is matched with the corresponding mixing speed of each preset water-cement ratio range to obtain the preset mixing speed of cement mortar material in the production equipment, where i represents the number of each material component, i = 1, 2, ..., a.
[0026] The materials include crushed stone, pebbles, and natural sand.
[0027] The identification of the standard deviation stress corresponding to the thrust of the blades within the production equipment includes: obtaining the structural setting radius R of the production equipment and the corresponding structural setting height H of each blade in the axial space. j The total volume V0 of cement mortar poured into the production equipment was obtained, and the corresponding standard deviation stress of the blade thrust within the production equipment was calculated. Where H (j+1) Let represent the height of the corresponding structural arrangement in the axial space of the (j+1)th blade, G represent the acceleration due to gravity, G = 9.8 N / kg, π represent pi, j represent the number of each blade's axial space, j = 1, 2, ..., b, and b represent the total number of blade axial spaces. This indicates the overall density of cement mortar materials within the production equipment. This represents the volume difference between the axial space of the j-th blade and the axial space of the (j+1)-th blade within the production equipment. Specifically, the height of the corresponding structure in the axial space of each blade is progressively numbered from the lowest layer to the highest layer.
[0028] The cement mortar condition monitoring module is used to divide the cement mortar mixing stage into various mixing time periods. During each mixing time period, three-dimensional images of the cement mortar inside the production equipment are collected intermittently. Taking the position of each blade in the production equipment as the center, the axial space of each blade is evenly divided, and the aggregate distribution uniformity index E and the adhesion index A between aggregate and mortar in the cement mortar inside the production equipment are analyzed.
[0029] The principle of acquiring three-dimensional images of cement mortar inside the production equipment is as follows: X-ray scanning of cement mortar inside the production equipment is performed from multiple angles using industrial CT technology. When X-rays pass through cement mortar, they will be attenuated to different degrees according to the different density structures inside the cement mortar (such as high aggregate density and relatively low mortar density). Then, by reconstructing the scanning data from multiple angles, a three-dimensional image of the internal structure of cement mortar is obtained.
[0030] Please see Figure 3 As shown, in a preferred embodiment, the analysis of the aggregate distribution uniformity index of cement mortar within the production equipment includes: extracting continuous frame images of cement mortar within the production equipment collected at the corresponding end time of the initial mixing period; identifying the distribution position and mud coating thickness of each aggregate particle of each size in each frame image; and statistically calculating the distribution particle quantity (m) of each aggregate particle of each size in the axial space of each blade in each frame image. zsj z represents the image number of each frame, z = 1, 2, ..., w, and s represents the aggregate number of each size, s = 1, 2, ..., f.
[0031] The term "aggregate size" refers to the range of the ratio of the longest axis to the shortest axis of the particle. For some slender or flat particles, the aspect ratio may be significantly greater than 1. For example, when certain flaky rock particles are used as aggregate, their aspect ratio may reach 5-10.
[0032] The mud coating thickness refers to the distance between the distribution positions of aggregate particles and the distribution positions of adjacent aggregate particles.
[0033] The particle size distribution of aggregates of different sizes in the axial space of each blade in each frame of the image was compared to analyze the difference in cement mortar particles within the production equipment in each frame of the image. In the formula m zs(j+1) This represents the particle size distribution of aggregate of size s in the z-th frame image within the (j+1)-th blade axial space, where Δm represents the pre-set reference difference particle size distribution of aggregate of the same size in the two blade axial spaces, max(m zsj ), min(m zsj ) represent the distribution of the largest and smallest aggregate particles in the axial space of each blade in each frame of the image, respectively, and d represents the total number of aggregate particles of each size.
[0034] The corresponding blind zone range of the production equipment is delineated. Based on the distribution position of each aggregate particle of each size in each frame of the image, the aggregate aggregation amount m′ in the corresponding blind zone of each blade in the axial space is identified. j .
[0035] The corresponding blind zone range of the production equipment refers to the area within a specified distance on the inner wall of the production equipment.
[0036] The aggregate aggregation amount in the blind zone refers to the cumulative number of aggregate particles of all sizes that are located within the blind zone and move within the same blade axial space in consecutive frame images.
[0037] Analyze the aggregate distribution uniformity index of cement mortar within the production equipment. Where m0 represents the preset blind zone aggregate reference aggregation amount, w represents the number of frame images, and e represents the natural constant.
[0038] In a further preferred embodiment, the bonding index between the aggregate and the mortar is analyzed by: identifying the average change (tv) of the slurry coating thickness of each aggregate particle of each size in all frames of cement mortar from continuous frame images within the production equipment. sr The migration consistency index of aggregates of each size is calculated by comparing it with the preset reference thickness change tv0. Where r represents the number of each aggregate particle, r = 1, 2, ..., h, and h represents the total number of aggregate particles belonging to each size of aggregate.
[0039] Detect the cement mortar vortex structure in each frame of the image and extract the segregation distance d of the cement mortar vortex structure in each frame of the image. z The bonding properties between aggregates and mortar in cement mortar within the production equipment were analyzed.
[0040] The segregation distance refers to the centrifugal distance of the cement mortar vortex pattern in the mixing shaft area.
[0041] The mixing speed adjustment module is used to retrieve the balanced mixing speed range of cement mortar in the production equipment based on the aggregate distribution uniformity index and the adhesion index between aggregate and mortar in the cement mortar in the production equipment, identify the set adaptability of the preset mixing speed, and determine the suitable mixing speed of cement mortar in the production equipment when the preset mixing speed is not suitable, and make real-time correction.
[0042] In a preferred embodiment, the step of retrieving the equilibrium mixing speed range of cement mortar within the production equipment includes: analyzing the degree of homogenization of the cement mortar mixing within the production equipment based on the aggregate distribution uniformity index and the aggregate-mortar adhesion index; comparing this with a preset benchmark homogenization threshold; and determining a first-level suitable mixing speed range U1 = [υ1] based on the aggregate distribution uniformity index and the aggregate-mortar adhesion index of the cement mortar within the production equipment. min ,υ1 max ] and the secondary adaptive stirring speed range U2=[υ2 min ,υ2 max ],υ1 min υ1 max These represent the lower and upper speed limits of the first-level adaptive mixing speed range, respectively, υ2 min υ2 max These represent the lower and upper speed limits of the secondary adaptive mixing speed range, respectively.
[0043] Specifically, the method for determining the first-level adaptive mixing speed range is as follows: the aggregate distribution uniformity index of the cement mortar in the production equipment is matched with the corresponding aggregate distribution uniformity index of each preset adaptive mixing speed range, and the adaptive mixing speed range to which the aggregate distribution uniformity index of the cement mortar in the production equipment belongs is matched, and recorded as the first-level adaptive mixing speed range.
[0044] The method for determining the secondary adaptive mixing speed range is as follows: the bonding index between aggregate and mortar is matched with the corresponding bonding index of each preset adaptive mixing speed range, and the adaptive mixing speed range to which the bonding index between aggregate and mortar belongs is determined, which is recorded as the secondary adaptive mixing speed range.
[0045] By comparing the primary and secondary adaptive mixing speed ranges, the equilibrium mixing speed range of cement mortar within the production equipment was determined. Where φ represents the empty set symbol, ∩ represents the intersection symbol, U0 represents the intersection speed range of the first-level adaptive stirring speed range and the second-level adaptive stirring speed range, and U′ represents the combined speed range of the first-level adaptive stirring speed range and the second-level adaptive stirring speed range.
[0046] In a further preferred embodiment, the formula for analyzing the degree of homogenization of cement mortar mixing within the production equipment is: Where E′ and A′ represent the aggregate distribution uniformity index and the aggregate-mortar bonding index of cement mortar in the production equipment, respectively, and corresponding preset appropriate indexes.
[0047] In a further preferred embodiment, identifying the adaptability of the preset mixing speed includes: setting the preset mixing speed of the cement mortar material in the production equipment to υ0, and setting the equilibrium mixing speed range of the cement mortar in the production equipment to U. balance = [υ′1,υ′2], and obtain the limiting stirring speed υ of the stirring shaft inside the production equipment. limit υ′1 and υ′2 represent the lower and upper limits of the equilibrium mixing speed range of cement mortar in the production equipment, respectively.
[0048] The preset mixing speed is compared with the balanced mixing speed range. If the preset mixing speed falls within the balanced speed range, the preset mixing speed of the cement mortar material in the production equipment is considered suitable; otherwise, it is considered unsuitable. This process determines the suitable mixing speed for the cement mortar in the production equipment. Simultaneously, the blade angle adjustment process is adapted to the preset mixing speed of cement mortar materials within the production equipment. Similarly, the... The blade angle is adjusted in the same process under different conditions.
[0049] In a further preferred embodiment, the specific process of real-time correction is as follows: based on the analysis content of the mixing speed adjustment module of the continuous frame image of cement mortar in the production equipment collected at the corresponding end time of the initial mixing time period, the analysis content of the mixing speed adjustment module of the continuous frame image of cement mortar in the production equipment collected at the corresponding end time of each mixing time period is similarly detected and corrected.
[0050] This invention analyzes the aggregate distribution uniformity and aggregate-mortar adhesion indices of cement mortar within production equipment to determine the optimal range of mixing speeds. By identifying the suitability of preset mixing speeds, the invention provides real-time adjustments to the mixing speed, ensuring thorough mixing of aggregates and mortar and preventing waste of raw materials due to insufficient mixing. Furthermore, a suitable mixing speed prevents prolonged high-load operation of the mixing equipment while maintaining cement mortar quality. For example, excessively fast mixing increases energy consumption; real-time adjustments allow the equipment to operate within a reasonable speed range, achieving energy savings.
[0051] The blade angle adjustment module is used to collect the cement mortar mixing resistance in the axial space of each blade in real time by means of stress plates installed on each blade component in the production equipment when the preset mixing speed is adapted, and to monitor the force characteristics of each blade component in the axial space of each blade, thereby determining the blade angle adjustment process.
[0052] In a preferred embodiment, the process of determining the blade angle adjustment includes: dividing the corresponding blind zone of the production equipment into bottom edge and barrel wall blind zone aggregate accumulation positions; based on the aggregate accumulation amount in the corresponding blind zone of each blade in the axial space, counting the aggregate accumulation amounts in the bottom edge and barrel wall blind zones; comparing and selecting the blind zone aggregate accumulation position with the maximum aggregate accumulation amount, and using this position as the adjustment zone; then selecting each blade in the corresponding adjustment zone as the calibration blade. For example, when the aggregate accumulation position is at the bottom edge, it indicates that the cement mortar has settled in the production equipment. In this case, several blades near the bottom edge are used as calibration blades, and the angle of the blades at the bottom of the barrel wall is adjusted to make them more inclined to contact the bottom of the barrel. When the aggregate accumulation position is at the barrel wall, it indicates that the cement mortar has agglomerated in the production equipment. Several blades near the middle barrel wall are used as calibration blades, and their rotation and pushing direction is changed so that the cement mortar can better flush the area near the barrel wall.
[0053] The cement mortar mixing resistance F of each calibrated impeller axial space within the production equipment, obtained from stress plate extraction and testing, is... pThe standard deviation stress ΔF of the blade thrust within the production equipment is extracted, and then the blade angle adjustment scale corresponding to the axial space of each calibrated blade is determined. p represents the number of each calibration blade axial space, p = 1, 2, ..., x, where x represents the total number of calibration blade axial spaces.
[0054] Specifically, the blade angle refers to the tilt direction with 0° in the vertical direction of gravity and 90° in the horizontal direction. When the blade angle is small, the stirring stress is relatively small because the fluid flow is relatively gentle during stirring. However, as the tilt angle increases, the fluid flow during stirring may become more complex and chaotic, leading to an increase in stirring stress.
[0055] This invention detects the amount of aggregate aggregation in the blind zone of the production equipment, adjusts the blade angle, and determines the adjustment angle, which helps to reduce the agglomeration and settling of cement mortar in the production equipment, thereby making the cement mortar mixing effect in the production equipment more uniform.
[0056] The stirring termination determination module is used to determine the stirring stop time by analyzing the uniformity of the force on the blades.
[0057] In a preferred embodiment, the determination of the stirring stop time includes: based on the cement mortar stirring resistance in the axial space of each blade, obtaining the equilibrium differential stress of the blades in the production equipment in real time, comparing it with the standard deviation stress of the blade thrust in the production equipment, and obtaining the time when the equilibrium differential stress of the blades in the production equipment is equal to the standard deviation stress of the blade thrust in the production equipment, which is recorded as the stirring stop time.
[0058] The equilibrium differential stress of the blades in the production equipment refers to the mean deviation of the cement mortar mixing resistance in the axial space of each blade.
[0059] This invention indirectly reflects the uniformity of material mixing within the mixing container by detecting the uniformity of the stirring resistance deviation of each impeller within the production equipment. At this point, stirring is stopped. This method of identifying stirring resistance directly reflects the mechanical state during the stirring process, offering high directness. The magnitude and trend of stirring resistance accurately reflect key information such as the degree of material mixing and the operating status of the agitator. Compared to other indirect identification methods, such as judging the stirring state by observing changes in the color of material images, the stirring resistance identification method is more accurate and reliable.
