Technical Field

[0001] The invention relates to the technical field of resource utilization of construction waste, and in particular to a method for treating construction waste. Background Art

[0002] During the stacking and landfilling process of construction waste, the sewage that seeps due to rainwater leaching and surface / groundwater immersion will cause serious pollution to the surrounding surface water and groundwater. After sorting, removal or crushing, most of the construction waste can be reused as renewable resources, which not only reduces the exploitation of natural resources, but also reduces production costs, with environmental and economic benefits. The existing technology obtains aggregates by sorting, crushing and screening the waste, so that construction waste resource processing enterprises can adjust product varieties and quantities according to the market needs of the products, thereby promoting the development of the construction waste resource processing industry. However, the control accuracy of the construction waste processing process is insufficient, and the control accuracy of the quality of the treated waste is insufficient, which can easily cause environmental pollution and affect the subsequent processing efficiency.

[0003] Chinese patent application number: CN201410171333.0 discloses a method for treating construction waste, which belongs to the field of resource utilization of construction waste. The method includes: a sorting step, a coarse crushing step, a magnetic separation step, a medium crushing step, a three-layer screening step, and a step of preparing unburned bricks and a material separation step respectively, a step of preparing building material aggregates one and a step of preparing building material aggregates two respectively after the material separation step, and a recycling step in the step of preparing building material aggregates one and the step of preparing building material aggregates two. The production of building material aggregate products and unburned brick products using construction waste is realized in a controllable manner. The method enables construction waste resource processing enterprises to adjust product varieties and quantities according to the market needs of products, produce marketable products, reduce investment, save land, and promote the development of the construction waste resource processing industry.

[0004] However, the prior art still has the following problems:

[0005] The lack of control accuracy in the construction waste treatment process and the lack of control accuracy in the quality of the treated waste can easily cause environmental pollution and affect the efficiency of subsequent treatment. Summary of the invention

[0006] To this end, the present invention provides a method for treating construction waste, which is used to overcome the problems in the prior art of insufficient control accuracy of the construction waste treatment process and insufficient control accuracy of the quality of the treated waste, which easily causes environmental pollution and affects the subsequent treatment efficiency.

[0007] To achieve the above-mentioned purpose, the present invention provides a method for treating construction waste. The method comprises:

[0008] Step S1, placing the waste target in a crusher to crush the waste target, and using a conveyor belt to input the crushed waste target into a winnowing machine for winnowing;

[0009] Step S2, detecting the mass of the waste target after the air separation treatment, using a magnetic separator to adsorb the ferromagnetic substances in the waste target after the air separation treatment, detecting the mass of the ferromagnetic substances, and conveying the remaining waste target that has not been adsorbed to a vibrating screen for vibrating screening treatment;

[0010] Step S3, collecting images of waste targets after vibration screening, determining the size of the waste targets based on the images, and analyzing whether the treatment of the current batch of waste targets is qualified based on the size of the waste targets.

[0011] When the treatment is initially determined to be unqualified, a secondary determination is made as to whether the treatment of the current batch of waste targets is qualified based on the time domain discreteness of the area of ​​each of the waste targets, or the cause of the unqualified treatment is analyzed based on the size of the waste targets, and a corresponding treatment method is selected based on the analysis result;

[0012] Step S4, the waste material after the vibration screening process is input into the crusher again for secondary crushing to obtain aggregate.

[0014] Collect images of the current batch of waste targets,

[0015] Determine the area of ​​each waste object in the image,

[0016] Calculate the average area of ​​each waste target,

[0017] If the average area is less than or equal to the first preset average area standard threshold, it is determined that the treatment of the waste target of the current batch is qualified, and the waste target of the current batch is subjected to secondary crushing treatment;

[0018] If the average area is greater than the first preset average area standard threshold and less than or equal to the second preset average area standard threshold, determining whether the treatment of the current batch of waste targets is qualified based on the time domain discreteness of the area of ​​each of the waste targets;

[0019] If the average area is greater than the second preset average area standard threshold, it is determined that the treatment of the waste target in the current batch is unqualified, and the reasons for the unqualified treatment are analyzed based on the average area.

[0020] Furthermore, the second determination of whether the treatment of the current batch of waste targets is qualified based on the time domain discreteness of the area of ​​each waste target includes:

[0021] determining the area of ​​each of the waste objects in the current batch in the image,

[0022] Calculate the variance of the area of ​​each waste target,

[0023] If the variance is less than or equal to the preset variance, it is determined that the treatment of the current batch of waste targets is unqualified, and the reasons for the unqualified treatment are analyzed based on the average area;

[0024] If the variance is greater than the preset variance, it is determined that the air separation process for the waste target is unqualified, and the operating power of the air separator is corrected based on the variance.

[0025] Further, the operating power of the winnowing machine is corrected based on the variance, wherein:

[0026] The increase in the operating power of the winnowing machine is positively correlated with the variance.

[0027] Furthermore, the reasons for the unqualified treatment of the waste target analyzed based on the average area include:

[0028] Calculating the difference between the average area and the second preset average area standard threshold,

[0029] If the difference is less than or equal to the first preset difference, the magnetic separation treatment of the waste target is determined to be unqualified, and the current of the magnetic separation device is corrected based on the mass of the adsorbed ferromagnetic material;

[0030] If the difference is greater than the first preset difference and less than or equal to the second preset difference, determining the reason for the unqualified treatment of the waste target based on the distribution of the abnormal waste target;

[0031] If the difference is greater than the second preset difference, it is determined that the crushing process for the waste target is unqualified, and the rotation speed of the crusher is increased based on the difference.

[0032] Furthermore, the current of the magnetic separation device is corrected based on the mass of the adsorbed ferromagnetic material, including:

[0033] Determine the mass of the waste target after the air separation process to obtain a first characteristic mass,

[0034] Determine the mass of the ferromagnetic material screened out and obtain the second characteristic mass.

[0035] Solve the ratio of the second characteristic mass to the first characteristic mass to obtain the magnetic target ratio.

[0036] The current of the magnetic separation device is increased based on the proportion of magnetic targets, wherein:

[0037] The increase in current is negatively correlated with the proportion of magnetic targets.

[0038] Furthermore, the second determination of the reasons for the unqualified treatment of the waste targets based on the distribution of the abnormal waste targets includes:

[0039] determining the contour of the waste object after vibration screening in the image,

[0040] Determine the anomaly contour,

[0041] Determine the location of the abnormal contour,

[0042] If the abnormal profile distribution is concentrated, it is determined that the crushing process for the waste target is unqualified, and the rotation speed of the crusher is increased based on the difference;

[0043] If the abnormal profile distribution is dispersed, the vibration screening treatment for the waste target is determined to be unqualified, and the vibration frequency of the vibration device is adjusted based on the dispersion density.

[0044] Further, the vibration frequency of the vibration device is adjusted based on the dispersion density, wherein:

[0045] The increase in vibration frequency is positively correlated with the dispersion density.

[0046] Further, the rotation speed of the crusher is increased based on the difference, wherein:

[0047] The increase in the rotation speed is positively correlated with the difference.

[0048] Compared with the prior art, the beneficial effect of the present invention lies in that, in the present invention, a crusher is first used to crush the waste to reduce the size of the waste for subsequent treatment, and then a winnowing machine is used to separate light materials in the waste, and waste paper, plastics, etc. in the waste are separated from heavy materials such as concrete by wind power, and a magnetic separator is used to adsorb magnetic materials in the waste, and then the remaining waste is subjected to vibration screening treatment to obtain aggregates of different specifications, and whether the treatment process is qualified is analyzed based on the size of the waste after the vibration screening treatment, thereby ensuring the quality of the screened materials, avoiding secondary treatment due to unqualified quality, and improving the treatment efficiency of construction waste.

[0049] Furthermore, the present invention collects images of construction waste after screening, and determines the size of the waste according to the area of ​​the processed construction waste in the image, rather than detecting the size of each part of the waste in turn, thereby improving the analysis efficiency, and analyzing whether the treatment process is qualified based on the size of each waste. When the size of the waste is large, it is determined that its treatment process is unqualified, and the reason for its unqualifiedness is analyzed according to the size. Based on the analysis result, the corresponding treatment method is determined, and the parameters in the construction waste treatment process are adjusted in time, thereby improving the subsequent treatment efficiency.

[0050] Furthermore, the present invention first determines the area of ​​each waste in the image, calculates the variance of each area, and then makes a secondary judgment based on the variance whether the treatment of the current batch of construction waste is qualified. When the variance is large, the air separation treatment is judged to be unqualified, and the operating power of the air separator is increased, thereby separating the light materials mixed in the waste and improving the quality of the treated waste.
