Description

Technical Field

[0001] This invention relates to the field of building material testing technology, specifically to a device and method for detecting and analyzing the mud content of sand and gravel. Background Technology

[0002] In construction engineering, concrete mixing plants, and sand and gravel yards, the mud content of sand and gravel is a key indicator affecting concrete performance (such as strength, durability, and workability). Traditional methods for testing the mud content of river sand mainly rely on national standards (such as GB / T14684-2011 "Sand for Construction"). The core steps include: sampling, quartering reduction, drying, weighing, washing, re-drying, and re-weighing. Finally, the mud content is calculated using a formula. The entire process is almost entirely dependent on manual operation, which is inefficient and has low accuracy.

[0003] To improve detection efficiency, some auxiliary equipment or improved methods have emerged in the prior art. For example, Chinese Patent No. CN220794796 U discloses a device for detecting the mud content of sand and gravel aggregates. The device includes a hollow shell with a balance support at the top and an electronic balance fixed at the end of the balance support. It also includes an electric push rod vertically connected to the electronic balance, with its bottom inserted into the hollow shell and a screening and washing box fixed at its end. The hollow shell is divided into an upper cavity, a middle cavity, and a lower cavity by an upper automatic door and a lower automatic door. The side wall of the lower cavity is equipped with a sound wave emitting device immersed in water, and its bottom is connected to an external wastewater sedimentation tank. The side wall of the middle cavity is equipped with a microwave heating device.

[0004] However, existing testing equipment usually relies on manual labor to complete steps such as sample reduction and loading, cleaning endpoint determination, and sand content calculation, which has low efficiency and low accuracy. At the same time, only one sample after reduction can be tested at a time, and it is impossible to test two parallel samples simultaneously. This single-sample testing method not only leads to low testing efficiency, but also lacks synchronous comparison and verification of parallel samples, making it difficult to guarantee the stability and reliability of the test results.

[0005] Therefore, how to improve the detection efficiency of sand content and achieve simultaneous and stable detection of two parallel samples has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a highly efficient, stable and reliable equipment and method for detecting and analyzing the mud content of sand and gravel.

[0007] To achieve the above objectives, the sand and gravel mud content detection and analysis equipment provided by the present invention includes a weighing module, a drying module, and a cleaning module, as well as a reduction module, a transfer module, and a control module. The sample reduction module wets the sample and reduces it into two parallel samples based on the quartering method, which are then placed into two separate washing tanks. The transfer module can drive the two washing tanks to reciprocate synchronously in the weighing module, drying module, and washing module. The cleaning module can monitor the turbidity value of the wastewater from the cleaning tank in real time during the cleaning of parallel samples. The drying module can perform initial drying on the parallel samples moistened by the reduction module, and can also perform secondary drying on the parallel samples cleaned by the cleaning module. The weighing module can acquire the weight data of two parallel samples after the first drying and the second drying, respectively. The control module can control the working state of the cleaning module based on the turbidity value, and can also calculate the mud content of each of the two parallel samples and the average mud content of the samples based on the weighing data obtained by the weighing module.

[0008] Furthermore, it also includes a housing, with the weighing module and drying module disposed on one side of the housing, the reducing module and cleaning module disposed on the other side of the housing, and the transfer module disposed in the middle region of the housing.

[0009] Furthermore, the reduction module is connected to the feed inlet of the housing and is distributed above the cleaning module.

[0010] Furthermore, the cleaning module includes a cleaning frame, a mounting base, and a screen cover for cooperating with the cleaning tub. The mounting base and the screen cover are respectively disposed at both ends of the cleaning frame. The cleaning frame can drive the cleaning tub to swing, the screen cover can move along the axis of the cleaning frame, and the mounting base can rotate on the cleaning frame.

[0011] Furthermore, the cleaning module also includes a water turbidity detector, which is installed in the drainage path of the cleaning tank.

[0012] Furthermore, the reduction module includes a funnel, a four-branch pipe, and a water injection pipe. The water injection pipe can inject water into the funnel. The four-branch pipe is located at the bottom of the funnel. The inlet end of the four-branch pipe is provided with four sampling ports evenly distributed in four quadrants. The first and second sampling ports, which are diagonally distributed, are respectively connected to the first cleaning tank, and the second and fourth sampling ports, which are diagonally distributed, are respectively connected to the second cleaning tank.

[0013] Furthermore, the four sampling ports are respectively connected to the corresponding cleaning tanks through arc-shaped guide bends.

[0014] Furthermore, the transfer module includes a vertical transfer unit and a horizontal clamping arm. The vertical transfer unit can drive the horizontal clamping arm to move vertically. The horizontal clamping arm is used to clamp the washing tub and can move axially along the vertical transfer unit.

[0015] Furthermore, the outer wall of the cleaning tub is provided with a clamping flange for cooperating with the transverse clamping arm.

[0016] To achieve the above objectives, the detection method provided by the present invention, based on the aforementioned sand and gravel mud content detection and analysis equipment, includes: The weighing module obtains the gross weight of the two cleaning buckets respectively; The sample reduction module wets the sample and reduces it into two parallel samples using the quartering method, and then evenly puts them into two cleaning buckets. The transfer module transports the two cleaning buckets to the drying module for initial drying, and then to the weighing module to obtain the initial weight of the two parallel samples. The transfer module then transfers the two cleaning buckets to the cleaning module, where two parallel samples are cleaned simultaneously. During the cleaning process, the turbidity value of the wastewater is monitored in real time, and the control module determines the cleaning endpoint based on the turbidity value and stops the cleaning. The transfer module transfers the two cleaned buckets to the drying module for secondary drying, and then to the weighing module to obtain the final weight of the two parallel samples. The control module calculates the mud content of a single sample and the average mud content of the samples based on the initial and final weights of each parallel sample.

[0017] The sand and gravel mud content detection and analysis equipment and method provided by this invention automatically divides the sample into four parts using a reduction module, ensuring uniform distribution of two parallel samples. The control module determines the washing endpoint based on the real-time monitoring of the drainage turbidity value by the washing module, eliminating subjective errors from manual judgment and improving the consistency of parallel sample results, thereby enhancing the reliability of the detection data. Simultaneously, the two parallel samples are transported and tested synchronously within the equipment, improving detection efficiency and ensuring the stability and reliability of the results through synchronous comparison and verification. Furthermore, the control module can quickly calculate the individual sand content of each parallel sample and obtain the average sand content based on both, further simplifying the operation process and ensuring accurate and reliable calculation results.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0022] See Figure 1 and Figure 2 The image shows an example of the sand and gravel mud content detection and analysis equipment provided by the present invention.

[0023] As shown in the figure, the sand and gravel mud content detection and analysis equipment in this example mainly includes a weighing module 1, a drying module 2, a control module 3, a reduction module 4, a cleaning module 5, and a transfer module 6.

[0024] The sample reduction module 1 wets the input sample and reduces it into two parallel samples based on the quartering method. These parallel samples are then placed into two washing tanks 7. The transfer module 6 drives the two washing tanks 7 to reciprocate synchronously within the weighing module 1, drying module 2, and washing module 5. The washing module 5 monitors the turbidity value of the drainage from the washing tanks 7 in real time during the washing of the parallel samples. The drying module 2 performs initial drying on the parallel samples wetted by the sample reduction module 4 and performs secondary drying on the parallel samples washed by the washing module 5. The weighing module 1 acquires the weight data of the two parallel samples after the initial drying and the secondary drying, respectively. The control module 3 controls the working state of the washing module 2 based on the turbidity value and calculates the mud content of each parallel sample and the average mud content of the samples based on the weighing data acquired by the weighing module 1, thereby improving the detection efficiency and ensuring stable and reliable detection results.

[0025] Combination Figure 1 Specifically, this equipment includes a housing 8, a weighing module 1 and a drying module 2 located on one side of the housing 8, a reduction module 4 and a cleaning module 5 located on the other side of the housing 8, and a transfer module 6 located in the middle area of ​​the housing 8. By arranging the transfer module 6 in the middle area, the transfer module 6 can smoothly and efficiently drive the cleaning tank 7 to move within the housing 8 and transfer it to the detection modules on both sides, thereby optimizing the transfer path, reducing motion interference, and improving the overall smoothness of the operation and detection efficiency.

[0026] Combination Figure 2 Furthermore, the sample reduction module 4 is connected to the feed inlet 81 of the housing 8 and is located above the cleaning module 1. When a sample is put into the feed inlet 81, the sample can be reduced to four parts by the sample reduction module 4, ensuring that the sample is evenly distributed to the two cleaning tanks 7, improving the accuracy of subsequent parallel testing, and realizing the integrated operation of feeding and reduction, simplifying manual steps.

[0027] Combination Figure 1 In conjunction with this, the drying module 2 and the cleaning module 5 are distributed opposite each other, and the weighing module 1 is set below the drying module 2. This allows the transfer module 6 to quickly move the cleaning tank 7 horizontally after the cleaning module 5 cleans the sample, transfer it to the drying module 2 for drying, and then move the cleaning tank 7 vertically to the weighing module 1 for weighing. This layout of the drying module 2, cleaning module 5, and weighing module 1 can effectively match the detection process flow, reduce idle travel and waiting time, and thus improve detection efficiency.

[0028] Combination Figure 3 and Figure 4Specifically, the cleaning module 5 includes a cleaning rack 51 and a mounting base 52. The cleaning rack 51 and the mounting base 52 can cooperate to support two cleaning buckets 7, so that after the sample is divided into four parts by the reduction module 4 above the cleaning module 5, the two parallel samples formed can be directly put into the two cleaning buckets 7 located in the cleaning module 5, realizing the synchronous reception and parallel processing of the samples.

[0029] Furthermore, the cleaning rack 51 includes a fixed bracket 511 disposed on the inner walls of both sides of the housing 8 and a swing bracket 512 disposed on the fixed bracket 511. The swing bracket 512 is L-shaped and the placement base 52 is disposed at the bottom of the swing bracket 512, so that the two cleaning buckets 7 can be placed on the placement base 52 to receive the two parallel samples put in by the reduction module 4.

[0030] Preferably, the base 52 is further provided with a plurality of positioning posts 521, which are arranged in a circular pattern and cooperate to form a mounting cavity adapted to the outer diameter of the cleaning tub 7, so that the cleaning tub 7 is placed in the mounting cavity and the positioning posts 521 can limit the cleaning tub 7 to prevent it from falling.

[0031] In conjunction with this, the sample reduction module 4 includes a funnel 41, a four-way branch pipe 42, and a water injection pipe 43. The funnel 41 is connected to the feed inlet 81 of the housing 8. The water injection pipe 43 is installed in the funnel 41 and connected to a water source outside the housing 8. It can inject water into the funnel 41 to moisten the sample, assist the sample to be fed smoothly along the funnel 41, and at the same time reduce the dust generated when the sample is fed in and the retention of the sample in the funnel 41, thus avoiding material waste.

[0032] Furthermore, the funnel 41 is preferably distributed in an inverted cone shape, and the four-branch pipe 42 is set at the bottom of the funnel 41. It can receive the sample flowing out of the funnel 41 and divide the sample into two uniform parallel samples based on the quartering method, so as to reduce the amount of sample to be tested in each cleaning tank 7 while ensuring the representativeness of the sample.

[0033] Combination Figure 5 Specifically, the inlet end of the four-branch pipe 42 is circularly distributed, and the inlet end is divided to form four sampling ports evenly divided into four quadrants. The first sampling port 421 and the second sampling port 422, which are located diagonally, are respectively connected to the first cleaning tank 71, and the third sampling port 423 and the fourth sampling port 424, which are located diagonally, are respectively connected to the second cleaning tank 72.

[0034] Furthermore, the four sampling ports are connected to the corresponding cleaning tanks 7 via arc-shaped flow guide bends 425. Each arc-shaped flow guide bend 425 extends downward from the corresponding sampling port and bends smoothly to form an arc-shaped flow guide channel. This can prevent the sample from accumulating or getting stuck at the corner of the pipeline, reduce the flow resistance during the sample's fall, and allow the wetted sample to flow smoothly along the pipe wall to the corresponding cleaning tank 7. At the same time, it ensures that the fall path length of the two diagonally opposite samples is basically consistent with the flow state, improves the uniformity of the quartering method and the representativeness of parallel samples, and thus improves the accuracy of the mud content detection results.

[0035] Combination Figure 3 and Figure 4 Based on the above structure, after the sample is put into the feed inlet 81, it is evenly gathered at the bottom of the funnel 41 based on the inverted cone structure. Under the moistening and guiding effect of the water flow injected by the water injection pipe 43, it flows smoothly into the inlet end of the four-way branch pipe 42 and is divided into four parts by the four sampling ports separated by the inlet end. Among them, the two diagonally distributed samples can enter the same cleaning tank 7 along the arc-shaped guide bend 425 to form a new sample. Thus, the original sample is reduced into two parallel samples based on the quartering method and put into two cleaning tanks 7 respectively, realizing the automated and synchronous collection of samples, so as to reduce the amount of manual work and improve the detection efficiency.

[0036] After two moist parallel samples are placed into the cleaning tank 7, the transfer module 6 will drive the two cleaning tanks 7 to reciprocate synchronously in the weighing module 1, drying module 2 and cleaning module 5 to ensure the reliability of the test. This will enable the synchronous testing of the two parallel samples, improve the testing efficiency, and also ensure the stability and reliability of the results through synchronous comparison verification.

[0037] It needs to be explained here, such as Figure 1 As shown, before the sample is added, the weighing module 1 weighs the two cleaning buckets to obtain the gross weight of each cleaning bucket 7 (the gross weight of the first cleaning bucket 71). The gross weight of the second washing tub 72 This is used for subsequent sand content calculations to ensure the accuracy of the test results.

[0038] like Figure 6 As shown, after two moistened parallel samples are placed into the washing tank 7, the transfer module 6 drives the two washing tanks 7 to be simultaneously transferred to the drying module 2. The drying module 2 performs an initial drying of the moistened parallel samples, and then the dried parallel samples are transferred to the weighing module 1 for weighing, thereby obtaining the initial weight of the two parallel samples (the initial weight of the parallel sample in the first washing tank 71). Initial weight of parallel samples in the second cleaning tank 72 ).

[0039] The initial drying of the moist parallel samples by the drying module 2 can remove the excess water injected into the samples by the water injection pipe 43 during the fractionation process, and can also remove the free water contained in the samples themselves. This eliminates the influence of externally introduced water and the original moisture content of the samples on the initial weighing, ensuring that the obtained initial weight can truly reflect the inherent mass of the parallel samples, thereby improving the accuracy of the test results.

[0040] Here, the weighing module 1 is equipped with two weighing devices, such as a balance, which can weigh the two washing tanks 7 simultaneously. The drying module 2 is equipped with a drying device, such as an infrared drying device, a microwave drying device, or an electric heating drying device, which can be adapted and adjusted according to specific applications, and can dry the parallel samples in the two washing tanks 7 simultaneously.

[0041] Combination Figure 3 In conjunction with this, the transfer module 6 includes a vertical transfer unit 61 and a horizontal clamping arm 62. The vertical transfer unit 61 and the horizontal clamping arm 62 can cooperate with each other to synchronously clamp and transfer two cleaning buckets 7, so as to realize the synchronous detection of two parallel samples.

[0042] The vertical transfer unit 61 includes vertical slide rails 611 mounted on the inner walls of both sides of the housing 8. Two sets of assembly brackets 612 are provided between the vertical slide rails 611 on both sides. The two sets of assembly brackets 612 are connected to each other, and each set of assembly brackets 612 has a clamping space for cooperating with a cleaning tub 7. At the same time, the assembly brackets 612 are slidably mounted on the vertical slide rails 611 and connected to a vertical drive device, so that the two sets of assembly brackets 612 can move up and down synchronously along the vertical slide rails 611 under the drive of the vertical drive device, thereby realizing the vertical movement function of the vertical transfer unit 61.

[0043] Furthermore, each of the two sets of assembly brackets 612 is provided with a transverse slide rail, and the transverse clamping arm 62 is slidably mounted on the transverse slide rail and connected to the transverse movement drive device, so that the assembly bracket 612 can drive the transverse clamping arm 62 to move vertically synchronously. At the same time, the transverse clamping arm 62 can move laterally along the assembly bracket 612 to realize the multi-directional movement of the transfer module 6 in the housing 8, and can stably cooperate with the detection modules on both sides of the housing 2.

[0044] Combination Figure 3 and Figure 6 Furthermore, each cleaning tub 7 has a clamping flange 73 on its outer wall for engaging with the transverse clamping arm 62. The transverse clamping arm 62 can move to below the clamping flange 73 and lift it from bottom to top, so that the clamping flange 73 abuts against the transverse clamping arm 62, thereby clamping the cleaning tub 7 and driving the cleaning tub 7 to be transferred to each detection module. When the cleaning tub 7 is stably placed, the transverse clamping arm 62 moves in the opposite direction to disengage from the clamping flange 73, thereby releasing the cleaning tub 7.

[0045] Based on the above structure, the transfer module 6 can drive the two cleaning tanks 7 to be transported synchronously, so as to realize the synchronous detection of two parallel samples.

[0046] After obtaining the initial weights of two parallel samples, the transfer module 6 drives the two cleaning tanks 7 to synchronously transfer the cleaning module 5. The two parallel samples are cleaned synchronously by the cleaning module 5 to remove sand and gravel from the parallel samples. During the cleaning process, the turbidity value of the drainage from the cleaning tank 7 is monitored in real time. The cleaning endpoint is determined based on the turbidity value, eliminating the subjective error of manual judgment and improving the reliability of the test.

[0047] Combination Figure 4 and Figure 7 To improve the cleaning and sand removal effect, the swing bracket 512 in the cleaning module 5 is connected to the fixed bracket 511 through a drive shaft. At the same time, the mounting base 52 is connected to the swing bracket 512 through a rotary motor. After the two cleaning buckets 7 are placed on the mounting base 52, the swing bracket 512 can swing around the fixed bracket 511 inside the housing 8, swinging the cleaning buckets 7 into an inclined state. At the same time, the mounting base 52 can drive the cleaning buckets 7 to rotate, so that the parallel samples in the cleaning buckets 7 can be fully tumbled and washed under continuous water flow, thereby improving the cleaning and sand removal effect.

[0048] Furthermore, the cleaning module 5 also includes a screen cover 53, which is connected to the swing bracket 512 via a screen slider 531. It can move along the axis of the swing bracket 512, so that after the cleaning tank 7 is placed on the mounting base 52, the screen cover 53 moves along the axis of the swing bracket 512 and is fitted on the top of the cleaning tank 7 to prevent the parallel sample in the cleaning tank 7 from being lost and causing errors in the test results.

[0049] Since mud content refers to the content of particles with a diameter less than 0.075 mm, preferably, the aperture of the screen cover 53 is configured to be 0.075 mm to ensure that particles smaller than 0.075 mm can be discharged from the screen cover 53, while particles larger than 0.075 mm are retained in the washing tank 7.

[0050] Meanwhile, the screen cover 53 is fitted on top of the cleaning tank 7 and can cooperate with the mounting base 52 and positioning post 521 at the bottom of the cleaning tank 7 to ensure the stable placement of the cleaning tank 7 and prevent it from falling off during the cleaning process, thereby improving the stability and reliability of the detection.

[0051] Combination Figure 8Furthermore, the cleaning module 5 also includes a flushing unit 54, which is composed of a flushing pipe. The flushing pipe is configured as a flexible corrugated pipe or a spiral coiled pipe. The screen slider 531 on the top of the screen cover 53 is provided with a flushing hole 532 adapted to the flushing unit 54, so that the flushing unit 54 can connect to the flushing hole 532 and connect to the water source outside the housing, so that the flushing unit 54 can move synchronously with the screen cover 53 and continuously flush the cleaning tank 7 through the flushing hole 532.

[0052] Combined Figure 6 In order to accurately determine the cleaning endpoint, the cleaning module 5 also includes a water turbidity detector 55 and a drain box 56. The drain box 56 is placed at the bottom of the cleaning frame 51 and located at the side of the housing 8. During the cleaning process, the swing bracket 512 synchronously drives the two cleaning buckets 7 to rotate to a horizontal distribution state, so that the cleaning water in the two cleaning buckets 7 continuously flows into the drain box 56 through the screen cover 53 and is mixed in the drain box 56.

[0053] Furthermore, the water turbidity detector 55 is installed in the drain box 56 at the confluence of the drainage paths of the two washing buckets 7, so that the water turbidity detector 55 can monitor the turbidity value of the mixed drainage after washing the two parallel samples in real time and continuously and feed it back to the control module 3.

[0054] In conjunction with this, the control module 3 can compare the turbidity value obtained by the water turbidity detector 55 with the preset turbidity threshold. When the turbidity value is lower than the preset turbidity threshold, it is determined that the cleaning end point has been reached, and the flushing unit is controlled to stop flushing to stop the cleaning.

[0055] Therefore, determining the cleaning endpoint by real-time monitoring of turbidity values ​​can ensure the accuracy of cleaning control, eliminate subjective errors from manual judgment, and improve detection reliability.

[0056] Furthermore, after the two parallel samples are washed simultaneously, the transfer module 6 drives the two washing tanks 7 to be transferred simultaneously to the drying module 2. The drying module 2 performs a second drying on the washed parallel samples, and then the dried parallel samples are transferred to the weighing module 1 for weighing, thereby obtaining the final weight of the two parallel samples (the final weight of the parallel sample in the first washing tank 71). Initial weight of parallel samples in the second cleaning tank 72 ).

[0057] Therefore, during the testing process, the weighing module 1 can sequentially obtain the gross weight of the first cleaning bucket 71. The gross weight of the second washing tub 72 The initial weight of the parallel samples in the first cleaning tank 71 Initial weight of parallel samples in the second cleaning tank 72 and the final weight of the parallel samples in the first cleaning tank 71 Initial weight of parallel samples in the second cleaning tank 72 .

[0058] Correspondingly, the control module can calculate the mud content of each of the two parallel samples and the average mud content of the samples based on the weighing data obtained by the weighing module. Specifically, Mud content of parallel samples in the first washing tank 71 The calculation is as follows:

[0059] Mud content of parallel samples in the second washing tank 72 The calculation is as follows:

[0060] Furthermore, the control module 3 can further determine the mud content of a single sample based on the parallel samples within the first washing tank 71. Mud content of single sample in parallel samples in the second washing tank 72 The average value is used to obtain the average mud content of the sample, thereby obtaining accurate mud content data and improving the accuracy and reliability of the test results.

[0061] Here, control module 3 can be constructed from an existing PLC.

[0062] Meanwhile, by comparing the mud content of parallel samples in the first washing tank 71... Mud content of single sample in parallel samples in the second washing tank 72 It can achieve synchronous comparison and verification. When the deviation between the mud content results of two parallel samples is small, it indicates that the detection process is stable and reliable, and the final average mud content result of the sample has a high degree of confidence.

[0063] Therefore, simultaneous transport and testing of two parallel samples in the equipment not only improves testing efficiency, but also ensures the stability and reliability of the results through synchronous comparison and verification.

[0064] This constitutes the sand and gravel mud content detection and analysis equipment provided by the present invention.

[0065] This invention also provides a detection method based on a sand and gravel mud content detection and analysis device constructed using the above-described scheme. This detection method includes: First, the weighing module 1 obtains the gross weight of the two cleaning buckets 7 respectively, and then transfers the two cleaning buckets 7 to the cleaning module 5; Next, the sample reduction module 4 wets the sample and reduces it into two parallel samples using the quartering method, and then evenly puts them into two washing buckets 7. The transfer module 6 transfers the two cleaning buckets 7 to the drying module 2 to perform initial drying on the moistened parallel samples, and then transfers them to the weighing module 1 to obtain the initial weight of the two parallel samples. The transfer module 6 then transfers the two cleaning buckets 7 to the cleaning module 5, where two parallel samples are cleaned simultaneously. During the cleaning process, the turbidity value of the wastewater is monitored in real time, and the control module 3 determines the cleaning endpoint based on the turbidity value and stops the cleaning. The transfer module 6 transports the two cleaning buckets 7 after cleaning to the drying module 1, where the parallel samples are dried a second time, and then transferred to the weighing module 1 to obtain the final weight of the two parallel samples. Based on the initial and final weights of each parallel sample, control module 3 calculates the mud content of a single sample and the average mud content of the sample.

[0066] The sand and gravel mud content detection and analysis equipment and method provided by this invention automatically divides the sample into four parts using a reduction module, ensuring uniform distribution of two parallel samples. The control module determines the washing endpoint based on the real-time monitoring of the drainage turbidity value by the washing module, eliminating subjective errors from manual judgment and improving the consistency of parallel sample results, thereby enhancing the reliability of the detection data. Simultaneously, the two parallel samples are transported and tested synchronously within the equipment, improving detection efficiency and ensuring the stability and reliability of the results through synchronous comparison and verification. Furthermore, the control module can quickly calculate the individual sand content of each parallel sample and obtain the average sand content based on both, further simplifying the operation process and ensuring accurate and reliable calculation results.
