Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanism aggregate detection, and in particular to a system and method for preparing full-automatic mechanism aggregate quality detection samples. BACKGROUND

[0002] In order to regulate the production and application of mechanism aggregate, countries have formulated a series of relevant standards and specifications. These standards and specifications make clear provisions for the chemical composition, physical properties, etc. of mechanism aggregate. For example, the standards such as "Construction Sand" (GB / T 14684) and "Construction Pebble, Crushed Stone" (GB / T 14685) of our country have strict restrictions on the chemical composition, mud content, mud block content, mica content, harmful substance content, etc. of mechanism sand and crushed stone.

[0003] In order to ensure the quality of mechanism sand, it needs to be strictly detected and controlled. In order to ensure the accuracy of detection, the produced mechanism sand needs to be prepared into a detection sample that can be used for detection. Usually, the process of obtaining mechanism aggregate, sample preparation of mechanism aggregate, and moving the prepared sample to a designated position all need to be completed by manual operation. Therefore, this process must cost human resources, and when the mechanism aggregate is prepared into a detection sample that meets the requirements, the quality of the prepared sample will vary with the professionalism of the operator, and there will be a situation that the quality of the prepared sample is not high. In addition, the prepared sample needs to be used in various detections, so the sample with unguaranteed quality will also lead to inaccurate detection results in the subsequent detection, or the sample cannot be used in the subsequent detection process due to not meeting the sample quality, thereby causing waste of mechanism aggregate. In addition, since mechanism aggregate is mostly produced by wet method, its water content varies greatly, from a few percent to 34 percent, and the adhesion of mechanism aggregate of different lithology and different powder content is also different. Therefore, sampling may fail, the sample may stick to the sampler, the thickness of mechanism aggregate on the belt is not uniform, etc. Therefore, it is an urgent problem to provide an automatic mechanism aggregate quality detection sample preparation system that can be randomly detected without stopping the production line and can guarantee the quality of the sample.

[0008] The system of the present application realizes automatic taking and automatic drying process by arranging the taking mechanism and the drying mechanism and arranging the control mechanism to automatically control them, realizes the completely automatic process from taking to discharging, and improves the efficiency of sample preparation. The drying mechanism in the present application is provided with two cylinders with different functions, the first cylinder is used for obtaining information of the manufactured aggregate, and the second cylinder is used for drying the manufactured aggregate, and because the information of the manufactured aggregate has been obtained before the drying operation, the drying parameters can be adjusted accordingly to ensure the quality of the sample of the manufactured aggregate to be detected after drying.

[0037] System embodiment for preparing a full-automatic artificial aggregate quality detection sample

[0038] As shown in Figure 2 , the system of the present embodiment comprises a material taking mechanism 1, a drying mechanism 2, a spiral feeding device 3 and a control mechanism.

[0039] As shown in Figure 3As shown, the taking mechanism 1 comprises a support part 11, a movable sliding table 12 arranged on the support part, a taking rod 13 arranged on the movable sliding table, and a taking hopper 14 arranged at the other end of the taking rod. The support part 11 is used to be connected with the lower fixed part of the manufactured aggregate conveying belt of the manufactured sand conveyor, so as to fix the support part on the manufactured sand conveyor. The control mechanism is used to control the movement of the taking rod 13 and the taking hopper 14, so that the taking hopper can obtain the manufactured aggregate on the manufactured sand conveyor, and the taking hopper 14 is controlled to move to the drying mechanism, so that the manufactured aggregate is unloaded into the drying mechanism. The movement of the taking rod and the taking hopper in the embodiment is to achieve the purpose of moving the taking hopper to the specified position. In order to achieve this purpose, the embodiment lists two implementable ways as follows: the taking rod is fixed on the slidable part of the movable sliding table, so that the taking rod can move horizontally with the horizontal movement of the slidable part. The taking rod is provided with a sliding rail, and the taking hopper is fixed by the sliding block arranged on the sliding rail, so that the taking hopper can be vertically (up and down) movable and fixed on the taking rod. Then, the taking rod is controlled to move horizontally and the taking hopper is controlled to move vertically up and down, so as to move the taking hopper to the specified position. Another way is that the taking rod is vertically movable and fixed on the slidable part of the movable sliding table, that is, the taking rod can not only move horizontally under the driving of the slidable part, but also can move vertically relative to the slidable part. Then, in this case, whether the taking hopper is fixed at a specific position of the taking rod or is movable and fixed at a specific position of the taking rod, the horizontal movement and the vertical up and down movement of the taking hopper can be realized only by the horizontal movement and the vertical up and down movement of the taking rod. The taking mechanism 1 is further provided with a material detection sensor. The material detection sensor is used to detect whether the taking hopper takes material or not, and when no material is taken within a set time, an alarm is given.

[0040] As Figure 3As shown, the drying mechanism includes a first cylinder 21 and a second cylinder 22 arranged below the first cylinder, a first feeding hopper 23 is arranged at the feeding port of the first cylinder for obtaining the mechanism aggregate on the material taking hopper, and a plurality of sensors are arranged at the first cylinder to obtain information data of the mechanism aggregate, wherein the plurality of sensors of the embodiment include a weight sensor 210 and a water content detection device 211, which can obtain weight information and water content information of the mechanism aggregate, and after the first cylinder obtains a sufficient amount of mechanism aggregate, the mechanism aggregate is transported into the second cylinder, the second cylinder includes a heating device for drying operation of the mechanism aggregate, and the heating device is controlled to heat and dry the mechanism aggregate in the second cylinder to obtain a mechanism aggregate sample to be detected, and when the heating and drying operation is performed, the control mechanism is used to control the drying parameters of the second cylinder according to the information data of the mechanism aggregate, the drying parameter in the embodiment is the heating power, and a stirring device is further arranged on the second cylinder, a stirring rod 220 of the stirring device extends into the inside of the second cylinder, the stirring rod is used to synchronously operate during the drying process, continuously turns over the mechanism aggregate to be detected, and can effectively avoid the caking phenomenon of the mechanism aggregate due to uneven heating, and ensures the loose state of the mechanism aggregate during the drying process. A cooling and heat dissipation device 221 is further arranged in the second cylinder, and the cooling and heat dissipation device is used to cool and dissipate heat of the dried mechanism aggregate, so as to prevent the high temperature of the dried mechanism aggregate from affecting the subsequent quality detection.

[0041] The spiral feeding device 3 is arranged at the discharging end of the second cylinder 22, and a second feeding hopper 31 is arranged at the feeding port of the spiral feeding device to completely obtain the mechanism aggregate sample to be detected discharged from the second cylinder, the spiral feeding device further includes a plurality of discharge ports, the plurality of discharge ports are used to respectively connect the feeding ends of different mechanism aggregate detection devices to transport the mechanism aggregate sample to be detected to each mechanism aggregate detection device, and a temperature detection device is arranged in the spiral feeding device, the temperature detection device is used to obtain the temperature of the mechanism aggregate sample to be detected in the spiral feeding device, when the temperature of the mechanism aggregate sample to be detected is higher than a set value, the spiral feeding mechanism is controlled to stop feeding, and after the temperature of the sample to be detected is lower than the set value, the spiral feeding mechanism is started to begin feeding. Figure 1 As shown, the plurality of discharge ports of the spiral feeding device of the embodiment are used to respectively connect the mechanism aggregate MB value detection device 4, the mechanism aggregate chemical component online monitoring device 6, the mechanism aggregate particle morphology detection device 7 and the mechanism aggregate mica content detection device 8, so as to automatically transport the mechanism aggregate sample to be detected into each detection device, and the detection of the MB value, the chemical component, the particle morphology and the mica content can be simultaneously started, and the detection efficiency is improved.

[0042] The system of the embodiment adopts a full-process automatic control architecture to realize unmanned operation from material taking to discharging and feeding. The process sequence is: online automatic control material taking mechanism→ material moisture content measurement mechanism→ material drying, stirring, temperature measurement and cooling mechanism→ spiral conveying, material distributing and discharging mechanism→ various detection devices. The full-automatic aggregate quality detection platform is convenient and simple to use, and the detection process is automated and intelligentized, and basically unmanned operation, with a very high safety factor, which can be comprehensively monitored in the production monitoring room.

[0043] The system for preparing full-automatic machine-made aggregate quality detection samples of the embodiment can realize the following processes:

[0044] After the central control room is opened by one key, the system automatically detects whether the belt is running, whether there is material on the belt, whether the equipment has running conditions, etc. If the conditions are not met, the system will have detailed prompts. When all conditions are met, the full-automatic aggregate quality detection platform starts to work, and the equipment automatically takes material from the belt. The material taking mechanism is provided with a material detection sensor, which can detect whether the aggregate is taken. If the material is not taken all the time, an alarm will be prompted. After the to-be-detected aggregate is discharged into the No. 1 barrel (i.e. the first barrel), the high-precision weight sensor and the moisture content detection device are configured to monitor the weight and moisture content data of the aggregate in real time, so as to ensure that the weight of the to-be-detected aggregate meets the subsequent detection standard. When the to-be-detected aggregate reaches a specific weight, the system will transport it to the No. 2 barrel (i.e. the second barrel). At this time, the system accurately controls the heating power of the No. 2 barrel according to the weight and moisture content data of the aggregate detected by the No. 1 barrel. In this way, efficient power saving can be realized, and the aggregate drying operation can be completed in the shortest time with the smallest power consumption. The stirring rod is installed in the No. 2 barrel, and the stirring rod operates synchronously during the drying process to continuously turn the to-be-detected aggregate. This can effectively prevent the aggregate from caking due to uneven heating, and ensure the loose state of the aggregate during drying, thereby providing more representative and uniform samples for subsequent detection, and effectively improving the accuracy and reliability of the subsequent detection results, avoiding the influence of aggregate caking on the judgment of the true characteristics of the detection equipment, and ensuring the data quality and scientificity of the entire detection process. The cooling device is also provided in the No. 2 barrel to prevent the high temperature of the dried aggregate from affecting the subsequent quality detection.

[0045] After drying, the to-be-detected aggregate is discharged into the spiral feeding device, which is provided with a temperature detection device. If the aggregate detection temperature is too high, the aggregate is sent to various detection mechanisms after cooling.

[0046] The system of the present application realizes automatic material taking and automatic drying process by setting the material taking mechanism and the drying mechanism and setting the control mechanism to automatically control them, realizes the fully automatic process from material taking to discharging, improves the efficiency of sample preparation. And the drying mechanism in the present application sets two different function barrels, the first barrel is used to obtain the information of the mechanism aggregate, and the second barrel is used to dry the mechanism aggregate, and because the information of the mechanism aggregate has been obtained before the drying operation, the drying parameters can be adjusted specifically to ensure the quality of the sample of the mechanism aggregate to be detected after drying. The detection system realizes automatic sampling and can adapt to various sites and various working conditions of mechanism sand conveying machine, and through the dustproof sliding table combination limiting material taking shovel, manual sampling is replaced, and sampling is automatically controlled on the mechanism aggregate conveying belt. In the present application, the sample is transported to each detection mechanism by the spiral feeding mechanism, and the subsequent detection efficiency is improved, and because the transportation process is not contacted by workers, the quality of the sample is further ensured, and the accuracy of the detection result is improved.

[0047] Each detection mechanism of the present embodiment includes mechanism aggregate MB value detection equipment, mechanism aggregate chemical composition online monitoring equipment, mechanism aggregate particle morphology detection equipment and mechanism aggregate mica content detection equipment. Because the system of the present embodiment realizes automatic detection process when preparing samples, in order to further improve the overall detection efficiency, the detection in each detection device can also be carried out in an automatic form to improve the detection efficiency and the accuracy of detection. The automatic detection process of each detection device is as follows:

[0048] 1. Mechanism aggregate MB value detection equipment.

[0049] The feeding mechanism conveys the aggregate to the mechanism aggregate MB value detection device, and then the electromagnetic vibration mechanism starts to slowly vibrate the bone to be detected into the weighing barrel provided with a weighing scale. The electromagnetic vibration mechanism has intelligent control function, can automatically and accurately control the electromagnetic vibration frequency according to the real-time detected aggregate weight, and then flexibly and effectively adjusts the discharging speed, realizes accurate control of the weight of the bone to be detected. When the weight of the bone to be detected reaches 200 grams (the precision is 0.1g), the electromagnetic vibration stops. Then the waste receiving barrel is automatically pushed to the lower part of the electromagnetic discharging port, the electromagnetic vibration device is started again, the discharging speed is reasonably controlled, the excess aggregate is vibrated into the waste barrel, and the waste discharging work is efficiently completed.

[0050] After the waste is discharged, the mechanical device (i.e. the overturning device) arranged on the weighing barrel is automatically controlled to overturn the weighing barrel, and the to-be-inspected material in the barrel is poured into the aggregate MB value detection hopper at a slow and uniform speed. This process strictly controls the pouring rate to avoid excessive speed causing dust loss and thus interfering with the accuracy of the experimental results. After the to-be-inspected material is transferred, the MB value detection system automatically starts the detection process. According to the operation sequence specified in the national standard "GB / T 14684-2022-Construction Sand", the system first accurately injects 500ML distilled water into the experimental beaker. A high-precision flowmeter is provided to ensure the accuracy of the flow. After the distilled water is injected, the discharge valve is automatically opened, and 200 grams of machine-made sand slowly falls into the experimental beaker. The hopper for storing the to-be-inspected aggregate is equipped with a vibrating device, which is started simultaneously during the discharge of the machine-made sand, and the high-frequency vibration promotes the complete transfer of the experimental material from the hopper to the detection, ensuring the reliability of the detection results.

[0051] Subsequently, the stirring device is automatically started to begin stirring at a speed of 600 rpm. After 5 minutes of continuous stirring, the system automatically reduces the speed to 400 rpm and adds methylene blue solution, which stops when the amount reaches 5 milliliters, and the stirring continues for 1 minute. Subsequently, the system automatically sucks the suspension in the beaker and drops it onto the detection filter paper. At this time, the filter paper is uniformly forwarded to the AI vision detection area under the action of the conveying device.

[0052] The AI vision module is then started to detect the precipitate on the filter paper. This module can accurately measure the width of the color halo around the precipitate and transmit the detection data to the central control display screen in real time. In this way, the staff can remotely view the detection results through the central control display screen, effectively avoiding errors caused by naked eye observation, and ensuring the accuracy and consistency of the detection data.

[0053] The system strictly follows the standard process to perform detection work. During the entire process, each step is automatically executed in an orderly manner, such as adding reagents in a timely manner according to the standard, and detecting the color halo multiple times. Until the entire detection process is completed, the software will record the total amount of methylene blue added in this experiment, and according to the calculation formula in the national standard "GB / T 14684-2022-Construction Sand":

[0054]

[0055] In the formula:

[0056] MB—methylene blue value, unit: grams per kilogram (g / kg);

[0057] V—total amount of methylene blue solution added, unit: milliliters (mL);

[0058] m0—sample mass, unit: grams (g);

[0059] 10 - Volume of methylene blue solution per kilogram of sample in terms of mass of methylene blue.

[0060] The sample mass has been recorded at the time of unloading, and the software automatically calculates the MB value of the artificial aggregate in this mechanism. The main influence on the MB value is the sample weight and the total amount of methylene blue solution. The AI recognition module accurately calculates the halo width, avoiding the blurred results when the human eye identifies, resulting in inaccurate total amount of methylene blue. It can effectively control the total amount of methylene blue added, and the MB value obtained is more accurate. Subsequently, the MB value monitoring system transmits the results to the large screen in the control room through the data transmission link, which clearly displays the detection situation, making it convenient for staff to monitor the detection situation in real time.

[0061] After the detection is completed, the instrument automatically pours the waste liquid in the experimental beaker into the waste treatment mechanism, and then starts the high-pressure flushing pump to circulate and clean the inner wall of the beaker. The graphite filter device in the waste treatment mechanism adsorbs methylene blue, and the distilled water after decolorization treatment flows into the flushing water bucket, realizing the recycling of water resources.

[0062] 2. Artificial aggregate chemical composition online monitoring equipment.

[0063] The height difference exists between the artificial aggregate chemical composition online monitoring system and the artificial aggregate MB value detection system, which causes the height difference between the spiral feeder and the feeding port of the artificial aggregate chemical composition online monitoring system. If the conventional method is used, manual adjustment of the height is required frequently, or complex mechanical and electrical control processes are added. To avoid such problems, a vacuum extractor is selected as a solution. One end of the vacuum extractor is connected to the spiral feeder, and the other end is connected to the vacuum feeding pipe of the artificial aggregate chemical composition online monitoring system. In this way, under the action of the vacuum extractor, the detected aggregate can be smoothly transported from the spiral feeder to the detection box, which not only eliminates the inconvenience of manual height adjustment, but also greatly reduces the mechanical and electrical control links, improving the convenience and stability of the overall conveying process.

[0064] After the detected aggregate is transported to the detection box of the artificial aggregate chemical composition online monitoring system, the weighing sensor in the box starts to work. When it is detected that the detected aggregate exceeds the entire detection box, the system stops the vacuum feeding according to the weight of the aggregate, and automatically starts the leveling roller. The leveling roller operates to remove the excess aggregate in the detection box and compacts the detected aggregate in the box, preparing for subsequent detection.

[0065] After the to-be-inspected aggregate box is conveyed to the to-be-inspected position, in order to effectively protect the detection lens and reduce the interference of other elements on the detection, the upper surface of the polyester film covering material is covered. Then, the detection lens is tightly attached to the polyester film, the detection lens emits X-rays to the to-be-inspected aggregate, and the generated fluorescent spectrum is collected. Finally, the detection result is obtained by analyzing the fluorescent spectrum. Although the conventional X-ray detection technology can realize chemical composition analysis, protective equipment is required during the detection process. The device is particularly equipped with a metal shell and a metal material detection constant temperature box, which can further enhance the X-ray shielding performance, and the maximum annual radiation dose is less than 2 mSv, which is much lower than the international safety threshold. In order to ensure the accuracy of the detection result, a multi-point detection technology is used, and the device controls the detection lens to move, selects four detection areas, and averages the values as the final detection result.

[0066] In order to ensure the accuracy of the experimental data and resist external environmental interference, the detection system adopts a fully enclosed box structure with a built-in high-precision temperature and humidity monitoring module. Through a closed-loop control system, environmental parameters are collected in real time, and the operation state of the heating / cooling unit and the dehumidification fan is dynamically adjusted, so that the temperature and humidity in the box are always stable within the preset threshold range, thereby ensuring the stability of the detection process and the accuracy of the results.

[0067] 3. Mechanism aggregate particle morphology detection equipment.

[0068] The mechanism aggregate particle morphology detection equipment of the present embodiment can use existing equipment that can realize automatic detection of mechanism aggregate particle morphology, for example, a Chinese invention patent application with application number 202410760162.9 and the name of a mechanism aggregate particle morphology rapid visualization detection device and scheme.

[0069] 4. Mechanism aggregate mica content detection equipment.

[0070] According to the "Quick Detection Method of Mica Content in Concrete Fine Aggregate" in the New Building Materials Journal, there are certain differences in particle morphology and color between mica and sand. Under the same compression ratio and the same size conditions, the size of the memory station formed is related to the change in the proportion of mica and sand in the fine aggregate. Therefore, by giving this difference, modern digital photography technology and professional digital photo software processing technology are used to realize the quantitative determination of the mica content in the fine aggregate.

[0071] The standard curve is established in advance, pure mica particles are extracted from fine aggregate, and mica content is added in a progressive relationship of 0.1% from 0 to 3% content (according to the standard requirement of GB / T 14684-2022-Construction sand, the mica content less than or equal to 2% belongs to the third type of sand, and more than 2% is unqualified), and each content is photographed according to the experimental steps to obtain several groups of test data, and the corresponding relationship curve of mica content and digital photo memory space occupation value is established. For other fine aggregate samples with unknown mica content, the digital photo occupation value of the test sample is obtained, and compared with the standard curve, the mica content of the test sample can be obtained.

[0072] The spiral feeder transports the dried aggregate to the mica detection position, and the aggregate is slowly poured into the funnel with a support in the mica detection position, the diameter of the discharge port is 15mm, the volume of the funnel is less than 200cm 3 , the sample box is placed below the funnel port, the sample box is a circular container with a diameter not less than 10cm and a depth not less than 2cm, the distance between the funnel port and the upper surface of the sample box is 5cm, the funnel switch is opened, the sample is freely poured into the test box and fills the entire sample box. The system will use a scraper to hang and drop the excess sample, and the scraped sample box is moved to the detection table, a high-definition camera is installed on the detection table, the test box is placed directly below the camera, the camera automatically takes a photo, and then the automatic arm takes out the test box and pours out the waste below the funnel, waiting for the next unloading. Repeat the above operation, after taking at least 5 photos, the software automatically intercepts the photos along the inner edge of the sample box, generates new photos, and automatically calculates the occupation value of the new photos. Remove one maximum value and minimum value, take the average value of the remaining photo occupation value, if the space value of 2 or more photos is more than 5% different from the average value, the result is invalid and needs to be retested. The device displays the intercepted image on the device screen and the central control large screen, and calculates the average value of the occupation values of the 5 photos. Compare the average value with the standard curve, calculate the mica content, and mark whether it is qualified according to the mica content.
