[0001] The present application relates to the technical field of resource utilization of construction waste, and specifically to a numerical control module, a method, a device and equipment for detecting the sand content of construction waste. Background Art

[0002] With the acceleration of urbanization, the construction industry has also developed rapidly, and the related construction waste has also increased. As a type of construction waste, the treatment of construction debris has attracted much attention.

[0003] Screening and washing construction waste to produce reclaimed sand can effectively utilize the waste, but this process incurs costs and harms the environment. Therefore, prior to screening and washing, the waste must be tested, and a comprehensive assessment of its economic and environmental benefits must be conducted. Among the many indicators tested for construction waste, sand content is a key indicator for this comprehensive assessment.

[0004] One existing method for testing sand content involves slurrying a soil sample, letting it sit, and visually observing the interface between sand and clay particles. However, because the interface between sand and clay particles is visually discernible, this method is difficult to quantify and, consequently, struggles to ensure accurate testing. Another method involves sampling, repeated rinsing, drying, and weighing. This method is complex, requiring sieving, washing, and drying, and is time-consuming. Furthermore, the testing process is difficult to complete on-site, making the results less timely.

[0046] The embodiments of the present application provide a CNC module, a method, a device and equipment for detecting the sand content of engineering slag, which solves the technical problem that the existing methods for detecting the sand content are difficult to ensure detection accuracy.

[0047] The following will be combined with the accompanying drawings in this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0048] For ease of understanding, please refer to FIG1 , which is a flow chart of a method for detecting the sand content of construction waste in an embodiment of the present application. As shown in FIG1 , the method for detecting the sand content of construction waste in this embodiment specifically includes:

[0049] Step 101: Acquire the temperature of a mixed solution, wherein the mixed solution is prepared by mixing construction waste to be tested and water.

[0050] It should be noted that the method in this embodiment can be executed by a CNC module, and the measurement of the temperature of the mixed solution can be obtained by a temperature detection unit such as a temperature sensor. Therefore, after the temperature sensor measures the temperature of the mixed solution, the temperature sensor can send the temperature to the CNC module, and the CNC module specifically executes the detection step of determining the sand content of the engineering slag based on the temperature.

[0051] The mixed solution is prepared from the construction waste to be tested and water. Therefore, in this step, the air-dried mass of the construction waste should be weighed before preparing the mixed solution, and the volume of the mixed solution should be adapted to the size of the container used to ensure the operability of the subsequent turbidity measurement.

[0052] Step 102: Based on the temperature-detection position calculation formula, determine the turbidity detection position of the construction waste in the mixed solution according to the temperature.

[0053] It should be noted that different particles have different sedimentation rates in water, and after engineering debris with different sand contents (the mass ratio of particles with a particle size greater than 0.075 mm to all particles) are uniformly mixed in an aqueous solution, the particle sedimentation rate varies significantly due to the differences in particle size and solution temperature, while the density of particles still suspended in the solution has a quantitative relationship with the turbidity of the solution. Therefore, in this embodiment, after obtaining the temperature of the mixed solution, the turbidity detection position of the engineering debris in the mixed solution is determined according to the temperature based on the temperature-detection position calculation formula. It is understandable that the temperature value used to calculate the detection position should be the actual temperature measured after the temperature of the mixed solution stabilizes.

[0054] Step 103: When a plurality of turbidity values ​​measured at the turbidity detection position are obtained, the sand content of the construction debris is determined based on the plurality of turbidity values ​​according to a turbidity-sand content calculation formula.

[0055] It should be noted that after calculating and determining the turbidity detection location for the construction waste, the turbidity of the mixed solution can be measured at the corresponding location using a turbidity detection unit such as a turbidity sensor. In this step, the construction waste is evenly dispersed in the water by repeatedly inverting or stirring the mixed solution. The mixed solution is then allowed to stand for a predetermined period of time, and the turbidity is measured after the standing time reaches a predetermined time.

[0056] The method for detecting the sand content of construction waste in this embodiment utilizes the principle of different sedimentation rates in particles of different particle sizes, and starts from the perspective of turbidity changes in the solution after the construction waste is slurried, calculates the turbidity detection position through the temperature of the solution, and directly quantitatively calculates the sand content of the construction waste through the turbidity detection results. That is, this embodiment detects the turbidity of the solution at a specific depth at a specific moment during the static state of the mixed solution, thereby obtaining the sand content of the construction waste. Compared with the method of visually observing the boundary between mud and sand after static state, the accuracy is significantly improved; compared with the test method of repeated rinsing, drying and weighing, the test steps are greatly reduced, the limitation of the measurement environment is eliminated, the test time is shortened, and the timeliness is significantly improved, thereby solving the technical problems of the existing sand content detection methods that are difficult to ensure detection accuracy and timeliness.

[0057] The above is the first embodiment of a method for detecting the sand content of construction waste provided in an embodiment of the present application. The following is the second embodiment of a method for detecting the sand content of construction waste provided in an embodiment of the present application.

[0058] Please refer to FIG2 , which is another flow chart of a method for detecting the sand content of construction waste in an embodiment of the present application. As shown in FIG2 , the method for detecting the sand content of construction waste in this embodiment specifically includes:

[0059] Step 201: Acquire the temperature of a mixed solution, wherein the mixed solution is prepared by mixing construction waste to be tested and water.

[0060] It should be noted that the description of step 201 is the same as that of step 101 in the first embodiment. For details, please refer to the description of the above step 101, which will not be repeated here.

[0061] Step 202: Based on the temperature-detection position calculation formula, determine the turbidity detection position of the construction waste in the mixed solution according to the temperature.

[0062] It should be noted that, in this step, the temperature-detection position calculation formula includes: y=ax 2 +bx+c;

[0063] Where y is the turbidity measurement location in mm, x is the temperature in °C, and a, b, and c are constants. a ranges from 0.015 to 0.03, b ranges from 2.5 to 5, and c ranges from 80 to 150. This formula is obtained by fitting based on Stoke's law, particle size, and the average density of common clay minerals.

[0064] Step 203: When a plurality of turbidity values ​​measured at the turbidity detection position are obtained, the sand content of the construction debris is determined based on the plurality of turbidity values ​​according to a turbidity-sand content calculation formula.

[0065] It should be noted that in this step, the turbidity-sand content calculation formula includes:

[0066] Where η is the sand content; p is a constant, the value range of p is: 600~650; V is the volume of the mixed solution; T1 is the turbidity value measured after standing for t1 seconds, the value range of t1 is: 30~50; m is the air-dried mass of the engineering waste to be tested; q is the adjustment coefficient, T2 is the turbidity value measured after waiting for t2 seconds, with a range of 120 to 200. T3 is the turbidity value measured after waiting for t3 seconds, with a range of 270 to 450. r, s, and e are all constants, with a range of 5 to 8 for r, 4 to 7 for s, 0.8 to 1.5 for e, and 0.6 to 0.8 for n. This formula is based on the quantitative relationship between turbidity and particle specific surface area and is adjusted using multiple turbidity measurements.

[0067] Step 204: Repeat steps 201 to 203 N times to obtain N+1 sand contents, where N is a natural number.

[0068] It should be noted that, in order to ensure the accuracy of the calculation results, in this embodiment, the sand content is measured multiple times, and the target sand content of the construction waste soil is finally obtained by integrating the multiple sand contents.

[0069] Step 205: Integrate N+1 sand contents to obtain the optimized sand content of the construction waste soil, and use the optimized sand content as the target sand content of the construction waste soil.

[0070] It is understood that the optimized sand content of the construction waste soil can be obtained by combining N+1 sand content ratios, and the average value of the N+1 sand content ratios can be used as the optimized sand content ratio, or the median of the N+1 sand content ratios can be used as the optimized sand content ratio. It should be noted that the above example is only an illustrative example, and those skilled in the art can make corresponding settings as needed.

[0071] The method for detecting the sand content of construction waste in this embodiment utilizes the principle of different sedimentation rates in particles of different particle sizes, and starts from the perspective of turbidity changes in the solution after the construction waste soil sample is slurried. The turbidity detection position is calculated by the temperature of the solution, and the sand content of the construction waste soil is quantitatively calculated directly through the turbidity detection results. Compared with the method of visually observing the mud and sand boundary after standing, the accuracy is significantly improved; compared with the test method of repeated rinsing, drying and weighing, the test steps are greatly reduced, the limitation of the measurement environment is eliminated, the test time is shortened, and the timeliness is significantly improved, which solves the technical problems of the existing sand content detection methods that are difficult to ensure detection accuracy and timeliness.
