Technical Field

[0001] The present invention belongs to the technical field of sand and gravel mud content and mud block content cleaning, and provides a sand and gravel washing device which can soak samples, rinse sand and gravel up and down, roll and brush evenly layer by layer while washing sand and gravel, detect whether it is clean, and blow dry after washing, and particularly relates to a multifunctional sand and gravel cleaning device and a working method thereof. Background Art

[0002] In construction, road engineering, concrete production and many other industrial fields, sand and gravel are an indispensable basic raw material. However, natural sand and gravel are usually mixed with impurities such as soil, clay, stone powder, mica, etc. The presence of these impurities will have a significant negative impact on the quality and performance of sand and gravel, and thus affect the quality and performance of various products with sand and gravel as raw materials. In construction concrete, sand and gravel containing more impurities will reduce the strength and durability of concrete, leading to structural safety hazards of buildings; in road paving, inferior sand and gravel will reduce the flatness and stability of the road and shorten the service life of the road.

[0003] Traditional sand and gravel washing methods and equipment often have single functions, low sand and gravel washing efficiency, and unsatisfactory cleaning effects. Some small sand and gravel washing plants are still using simple manual screening and water washing methods, which are not only labor-intensive and costly, but also unable to meet the requirements of large-scale industrial production for sand and gravel quality and output. With the rapid development of modern industry, the demand for high-quality sand and gravel is growing. There is an urgent need for an efficient, multi-functional, and highly automated sand and gravel washing device to solve the problems existing in the current sand and gravel cleaning process, improve the purity and quality of sand and gravel, meet the strict standards of various industries for high-quality sand and gravel, and at the same time reduce production costs, improve production efficiency and resource utilization, and reduce impact on the environment.

[0013] A sample collection unit, the sample collection unit comprising a movable sampling hopper and an electric track, the sampling hopper is connected to the control system via the electric track, and an automatic weighing device is connected below the sampling hopper;

[0016] The data processing and display unit includes a data acquisition card and a computer control system. The data acquisition card is connected to the conductivity sensor and the turbidity sensor. The computer control system is connected to a display screen. The computer control system has a built-in data analysis module.

[0017] As a preferred solution of the present invention, the first layer of filter plate is for coarse pore filtration, the second layer of filter plate is for fine pore filtration, and the third layer of filter plate is for fine filtration. Five different sieve apertures can be selected for the first and second layers, namely: 80μm, 630μm, 1.25mm, 2.5mm, and 5.00mm, to meet different requirements for cleaning of sand and gravel mud content and mud block content.

[0018] A working method of a multifunctional sand and gravel cleaning device comprises the following steps:

[0019] S1. Pour the sand and gravel to be cleaned into the rinse tray cage. The sand and gravel are evenly distributed on a layer of filter plates and soaked first. After soaking, prepare to start the cleaning operation. Start the rotating device to make it rotate forward. The output end of the motor drives the driven shaft to rotate forward, and then drives the follower shaft to rotate forward. Due to the threaded connection relationship between the one-way thread on the follower shaft and the displacement sleeve, the displacement sleeve starts to move downward. The displacement sleeve drives the rinse tray cage to move downward synchronously through the fixed rod. The sand and gravel in the rinse tray cage are rinsed up and down in the water as the rinse tray cage moves downward to preliminarily remove some impurities. When the sand and gravel need to be cleaned more finely, the rotating device is turned on. The motor drives the driven shaft to reverse, and the driven shaft also reverses accordingly, the displacement sleeve moves upward, and the rinse tray cage is lifted upward. At the same time, the driving gear drives the driven gear to rotate as the driven shaft reverses, and the driven gear drives the center rod to rotate, and the three cleaning sleeves on the center rod rotate accordingly, thereby driving the three groups of first cleaning roller brushes and second cleaning roller brushes to rotate, and evenly roll and brush the sand and gravel on the first filter plate, the second filter plate and the third filter plate to further remove impurities in the sand and gravel, such as sand and gravel mud, soil and clay, etc. The filter plates with different apertures play a role of layered filtration. After multiple rinsing and rolling, the cleanliness of the sand and gravel is improved;

[0020] S2. After the sand and gravel washing process reaches a certain stage or is completed, the control system starts the sample collection unit, and the sampling bucket moves to the predetermined position (near the rinse tray cage or each layer of filter plate) through the electric track to collect a certain amount of sand and gravel samples. The automatic weighing device records the quality data of the collected samples and transmits the data to the control system to ensure that the collected samples are representative and the quality data is accurate. The collected sand and gravel samples enter the transparent cylindrical dissolution tank of the dissolution and stirring unit through the pipeline (the electric valve on the pipeline is opened), the feed inlet electric valve is closed, a known volume of deionized water is added from the water inlet, and then the stirring paddle and the heating device are started. The stirring paddle stirs the solution at a certain speed, and the heating device heats the solution to room temperature so that the soluble impurities in the sand and gravel are fully dissolved in the water to form a uniform mixed solution to prepare for subsequent testing. After the stirring and heating process is completed, the solution is left to stand for a period of time to allow the solution to The suspended particles in the solution are precipitated stably, and then the high-precision conductivity sensor of the conductivity detection module and the turbidity sensor of the turbidity detection module measure the solution respectively. The conductivity sensor measures the conductivity value of the solution, and the turbidity sensor measures the turbidity value of the solution. The measurement data are transmitted to the data acquisition card in real time. The data acquisition card transmits the received conductivity value and turbidity value to the computer control system. The built-in data analysis module of the computer control system compares and analyzes the measurement value with the standard conductivity value range and turbidity value range of the washed sand and gravel pre-stored in the database. If the conductivity value and the turbidity value are both within the corresponding standard range, it is determined that the sand and gravel have been cleaned. If any of the values ​​exceeds the standard range, it is determined that the sand and gravel do not meet the cleaning requirements and need to be further cleaned or the cleaning process adjusted. The judgment result is intuitively displayed on the display screen, and the operator can take corresponding measures according to the displayed result;

[0021] S3. When the sand and gravel are cleaned and tested to meet the cleaning standards, start the waterproof oven inside the overflow bottom cover. The hot air blown out of the oven passes through each layer of filter plates upward to dry the sand and gravel on the filter plates. The oven continues to operate, and the hot air takes away the moisture in the sand and gravel, making the sand and gravel gradually dry. During the drying process, the sand and gravel can be turned over appropriately to speed up the drying speed and ensure that the sand and gravel reach the required degree of dryness for subsequent storage and use. When the sand and gravel are completely dry, turn off the oven, open the cleaning barrel, take out the cleaned and dried sand and gravel, and package or transport it to the next production link. At the same time, clean and maintain the device to prepare for the next sand and gravel washing operation;

[0022] S4. After the drying process is completed, ensure that the sand and gravel are in a stable state and prepare for weighing operations. The device is in a stopped state and all components are stationary. When the sand and gravel are in the rinse basket, the automatic weighing device measures the mass of the sand and gravel again and transmits the data to the control system for recording and subsequent processing. The operator can also manually record the weighing data, complete the weighing and subsequent processing, and after recording the final mass of the sand and gravel, open the cleaning barrel, take out the washed, dried and weighed sand and gravel, and package or transport them to the next production link according to actual needs. At the same time, clean and maintain the device to prepare for the next sand and gravel washing operation.

[0023] The beneficial effects of the present invention are:

[0024] The device of the present invention is driven by a motor, which can not only realize the up and down washing of the rinsing cage with sand and gravel, but also make the cleaning roller brush rotate synchronously with the rise of the rinsing cage to roll and brush the sand and gravel on each layer of filter plates. Compared with a single cleaning method, this composite cleaning action can more comprehensively and powerfully remove different types of impurities, such as sand and gravel mud, soil and clay, and significantly improve the cleaning degree;

[0025] Equipped with a filter plate with one layer of coarse pores, two layers of fine pores, and three layers of fine pores, the sand and gravel are filtered in layers during the whole cleaning process. The first layer of coarse pore filter plate first intercepts large particles of sand and gravel, the middle layer of filter plate captures medium-sized mica, and the fine three-layer filter plate does not miss the fine soil and clay. Each layer performs its own function, accurately screens out impurities, and gradually improves the purity of sand and gravel. The sieve holes of the first and second layers can be replaced according to different requirements, which is convenient for the implementation of more detection plans;

[0026] Built-in detection device, using conductivity detection module and turbidity detection module, respectively measures the cleanliness of sand and gravel from the two aspects of soluble impurities and insoluble impurities. Conductivity reflects the content of soluble impurities such as salt, and turbidity reflects the status of insoluble particles such as mud, sand and gravel. Multi-dimensional detection makes the judgment of the cleaning degree more accurate;

[0027] The whole process of sample collection, dissolution and mixing, data detection and analysis is automated. The control system connects each link in an orderly manner, reduces manual operation errors, and quickly outputs accurate judgments on the cleaning status of sand and gravel, making it convenient for operators to adjust the cleaning process in time and ensure the stable high quality of finished sand and gravel.

[0028] After the sand and gravel washing is completed and meets the standards, the device uses the waterproof oven in the overflow bottom cover to dry the sand and gravel directly in the washing barrel. The hot air blown out of the oven penetrates each layer of filter plates and quickly takes away the moisture. The sand and gravel can also be turned over during drying to accelerate drying. This simplifies the process, saves the trouble of additionally transporting sand and gravel to the drying equipment, and avoids secondary pollution during transportation. The dried sand and gravel can be immediately packaged or enter the next process;

[0029] It integrates sand and gravel washing, testing and drying in one body. All links are closely coordinated and seamlessly connected. From raw material input to finished product output, it can be completed in one stop. There is no need to circulate sand and gravel between multiple independent equipment. It not only reduces site occupation and equipment investment costs, but also shortens the overall production cycle and greatly improves production efficiency, which meets the needs of large-scale and high-efficiency sand and gravel washing production.

[0048] The driving gear 3 is meshed with a driven gear 12, a center rod 13 is fixedly sleeved on the driven gear 12, three cleaning sleeves 15 are fixedly sleeved on the center rod 13, a first cleaning roller brush 14 is rotatably mounted on one side of the three cleaning sleeves 15, and a second cleaning roller brush 16 is rotatably mounted on the other side of the three cleaning sleeves 15;

[0049] A filter plate 17 is installed in the rinsing tray cage 11, a second filter plate 18 is installed below the first filter plate 17, a third filter plate 19 is installed below the second filter plate 18, a sand and stone retaining plate 23 is installed below the first filter plate 17, the second filter plate 18 and the third filter plate 19, an overflow bottom cover 22 is provided below the sand and stone retaining plate 23, and a waterproof oven 21 is installed inside the overflow bottom cover 22;

[0050] A center hole 20 for the center rod 13 to pass through is provided in the middle of the first filter plate 17, the second filter plate 18 and the third filter plate 19. The tail end of the center rod 13 is rotatably mounted on the bottom inner wall of the cleaning barrel 10. A dual-purpose inlet and outlet port 9 is provided at one side of the bottom of the cleaning barrel 10.

[0051] Among them, the rotating device 1 is started, the rotating device 1 rotates forward, the rotating device 1 drives the driven shaft 2 to rotate forward, the driven shaft 2 drives the follower shaft 7 to rotate forward, thereby driving the displacement sleeve 5 to move downward, the displacement sleeve 5 drives the fixed rod 4 to move downward, the fixed rod 4 drives the rinse basket 11 to move downward, on the contrary, the rotating device 1 is reversed, the rinse basket 11 moves upward, which is used to rinse the sand and gravel up and down the rinse basket 11. When the rinse basket 11 moves upward, the driving gear 3 drives the driven gear 12 to rotate, the driven gear 12 drives the center rod 13 to rotate, the center rod 13 drives three cleaning sleeves 15 to rotate, and the three cleaning sleeves 15 drive three groups of first cleaning roller brushes 14 and second cleaning roller brushes 16 to rotate, which are used to evenly roll and brush the sand and gravel on the first filter plate 17, the second filter plate 18 and the third filter plate 19.

[0052] In this embodiment, the rotating device 1 serves as the power source of the entire sand and stone washing device. It controls the movement of other components by forward and reverse rotation, thereby realizing different sand and stone washing actions. It is the core driving component of the device operation. The driven shaft 2 connects the motor output end with the driving gear 3 and the driven shaft 7, transmits the power of the motor to the driving gear 3, drives it to rotate, and also transmits the power to the driven shaft 7, so that the driven shaft 7 can generate corresponding rotation when the motor rotates forward and reverse, thereby realizing the displacement movement of subsequent components. The driving gear 3 is meshed with the driven gear 12. When the driven shaft 2 rotates, the driving gear 3 rotates accordingly, and transmits the power to the driven gear 12, which plays the role of power transmission and conversion, which is the up and down movement of the rinse tray cage 11 and the rotation of the cleaning roller brush The one-way thread 6 on the follower shaft 7 cooperates with the displacement sleeve 5. When the follower shaft 7 rotates forward or reversely under the drive of the motor, the displacement sleeve 5 can move up and down under the action of the thread. The displacement sleeve 5 is rotatably installed on the follower shaft 7 to ensure that it will not rotate with the follower shaft 7 while moving up and down, thereby stably driving the fixed rod 4 and the rinse drawer cage 11 to move up and down, and realize the up and down washing of sand and gravel. The fixed rod 4 connects the displacement sleeve 5 and the rinse drawer cage 11, and transmits the up and down movement of the displacement sleeve 5 to the rinse drawer cage 11, so that the rinse drawer cage 11 can move up and down in the cleaning barrel 10. The rinse drawer cage 11 is used to hold sand and gravel. In the process of moving up and down, the sand and gravel are rinsed in water to preliminarily remove impurities.

[0053] At the same time, the filter plate structure in the rinse drawer cage 11 can filter the sand and gravel in layers. The driven gear 12 rotates under the drive of the driving gear 3, driving the central rod 13 to rotate. The central rod 13 serves as the mounting shaft of the cleaning sleeve 15, and transmits power to the cleaning sleeve 15, so that the cleaning sleeve 15 can rotate, and then drives the cleaning roller brush to roll and clean the sand and gravel on the filter plate. The cleaning sleeve 15 is fixed on the central rod 13, and rotates with the rotation of the central rod 13, thereby playing the role of transmitting power. The first cleaning roller brush 14 and the second cleaning roller brush 16 are respectively installed on both sides of the cleaning sleeve 15. When the cleaning sleeve 15 rotates, the roller brush rotates accordingly, and can evenly roll and brush the sand and gravel on the first filter plate 17, the second filter plate 18 and the third filter plate 19, effectively removing impurities in the sand and gravel, such as soil, mica, etc., and cooperating with the rinsing action of the rinse drawer cage 11 to improve the cleaning effect of washing sand and gravel. The first filter plate 17 is used for preliminary coarse filtration of sand and gravel, mainly through Filter larger particles of sand and gravel and other impurities; the aperture of the second filter plate 18 is smaller than that of the first filter plate 17, and is used to filter medium-sized impurities such as mica; the aperture of the third filter plate 19 is even smaller, and fine filtering is performed to filter fine impurities such as soil and clay. Through the layered filtration of the three-layer filter plate 19, the purity of the sand and gravel can be gradually improved. At the same time, the central hole 20 in the middle of the filter plate is used to allow the central rod 13 to pass through, ensuring that the cleaning roller brush can clean the sand and gravel on each layer of the filter plate. The sand and gravel retaining plate 23 is installed under each layer of the filter plate to prevent the sand and gravel from falling and ensure that the sand and gravel are filtered and cleaned on the filter plate. At the same time, it also plays a certain supporting role, so that the filter plate can be stably installed in the rinse tray cage 11. The overflow bottom cover 22 is used to collect wastewater after washing the sand and gravel to prevent wastewater from overflowing. The waterproof oven 21 installed inside can blow air upward after the sand and gravel washing is completed, which is used to dry the sand and gravel on the filter plate so that the sand and gravel reach a suitable degree of dryness, which is convenient for subsequent storage and use.

[0054] Example 2

[0055] like Figure 1 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the detection device 100 is installed inside the cleaning bucket 10, and the detection device 100 includes a control system 110;

[0056] The sample collection unit includes a movable sampling bucket 120 and an electric track 122. The sampling bucket is connected to the control system 110 through the electric track 122. An automatic weighing device 124 is connected below the sampling bucket.

[0057] The dissolving and stirring unit 300 is composed of a transparent cylindrical dissolving tank 310. A sealing cover 320 is provided on the top of the dissolving tank 310. A feed inlet and a water inlet are provided on the sealing cover 320. The feed inlet is connected to the discharge port of the sampling hopper through a pipe 330. An electric valve 340 is provided on the pipe 330. A stirring paddle 350 and a heating device 360 ​​are installed inside the dissolving tank 310.

[0058] A detection unit, including a conductivity detection module 400 and a turbidity detection module 500, wherein the conductivity detection module 400 has a high-precision conductivity sensor 410 installed in the solution in the dissolution tank 310, and the turbidity detection module 500 has a turbidity sensor 510 installed on the side of the dissolution tank 310;

[0059] The data processing and display unit 600 includes a data acquisition card 610 and a computer control system 620 . The data acquisition card 610 is connected to the conductivity sensor and the turbidity sensor 510 . The computer control system 620 is connected to a display screen 630 . The computer control system 620 has a built-in data analysis module 640 .

[0060] In this embodiment, the control system 110 serves as the core control part of the detection device 100, coordinating and directing the work of each unit. It receives data information from other components (such as the automatic weighing device 124, sensors, etc.), sends instructions according to preset programs and rules, controls the movement of the sampling bucket, the opening and closing of the electric valve 340, the operation of the stirring paddle 350 and the heating device 360, and the processing of the detection data and the display of the results, so as to ensure that the entire detection process is carried out in an orderly manner. The sampling bucket is used to collect samples from the sand and gravel in the cleaning bucket 10 (such as the sand and gravel on the rinsing cage 11 or the filter plate), and the electric track 122 provides a moving path for the sampling bucket, so that it can accurately reach the predetermined sampling position under the command of the control system 110, ensuring that the collected samples are representative and can truly reflect the quality of the sand and gravel after cleaning. The automatic weighing device 124 is connected below the sampling bucket to accurately measure the quality of the collected sand and gravel samples, and transmit the quality data to the control system 110, so as to provide basic data for determining the amount of water to be added and analyzing the impurity content in the subsequent dissolution and stirring process. To ensure the accuracy and scientificity of the detection process, the transparent cylindrical dissolution tank 310 is used as a container for dissolving and stirring the sand and gravel samples. Its transparent material makes it easy to observe the internal solution, provide a closed environment for the mixing of the sand and gravel samples and water, and the dissolution of impurities, and prevent external factors from interfering with the detection process. The sealing cover 320 ensures the sealing of the dissolution tank 310. The feed port is used to receive the sand and gravel samples collected by the sampling bucket, and the water inlet is used to add an appropriate amount of water to dissolve the soluble impurities in the sand and gravel. The electric valve 340 is installed on the pipeline 330, which can accurately control the feeding process of the sand and gravel samples and water, and accurately operate according to the instructions of the control system 110 to ensure that the amount of the sample and water meets the detection requirements. The stirring paddle 350 stirs the mixed solution of sand and gravel and water inside the dissolution tank 310, so that the soluble impurities in the sand and gravel can be fully and evenly dissolved in the water. The heating device 360 ​​can accelerate the dissolution process of impurities. By appropriately increasing the solution temperature, some impurities that dissolve slowly at room temperature can be dissolved faster, thereby improving the detection efficiency and ensuring the consistency and stability of the dissolution process.

[0061] The conductivity detection module 400 and the high-precision conductivity sensor 410 are installed in the solution in the dissolution tank 310 to measure the conductivity of the solution. Since impurities (such as salt, etc.) in the sand and gravel will affect the conductivity of the solution, the content of soluble impurities in the sand and gravel can be indirectly reflected by measuring the conductivity, so as to judge the cleanliness of the sand and gravel. The turbidity detection module 500 and the turbidity sensor 510 installed on the side of the dissolution tank 310 are used to measure the turbidity of the solution. The turbidity of the solution is mainly related to the insoluble impurities (such as soil particles, etc.) in the sand and gravel. The higher the turbidity value, the more insoluble impurities there are in the solution, and it can be inferred that the cleanliness of the sand and gravel is not enough. By detecting the turbidity, another important basis for judging whether the sand and gravel are clean can be provided. The data acquisition card 610 serves as the intermediate hub of data collection. The control unit 620 receives the electrical signals from the conductivity sensor and the turbidity sensor 510, converts them into digital signals, and transmits them to the computer control system 620, so as to ensure the accurate collection and transmission of the detection data and provide a reliable data source for the subsequent data processing. The computer control system 620 receives the data from the data acquisition card 610, and compares and analyzes the measured conductivity value and turbidity value with the preset standard value range of the cleaned sand and gravel through the built-in data analysis module 640, judges whether the sand and gravel are cleaned according to the comparison results, and displays the judgment results and related data on the display screen 630, so as to intuitively show them to the operator. The operator can timely understand the cleaning quality of the sand and gravel according to the information on the display screen 630, so as to decide whether further cleaning and other operations are needed.

[0063] like Figure 1 to Figure 6 As shown, based on the same concept as the above-mentioned embodiments 1 and 2, this embodiment further proposes that the first layer of filter plate 17 is for coarse pore filtration, the second layer of filter plate 18 is for fine pore filtration, and the third layer of filter plate 19 is for fine filtration. The first layer of filter plate 17 is used to filter sand and gravel, the second layer of filter plate 18 is used to filter mica, and the third layer of filter plate 19 is used to filter soil and clay.

[0064] The present invention also provides a working method of the multifunctional sand and gravel cleaning device, comprising the following steps:

[0065] S1. Pour the sand and gravel to be cleaned into the rinse basket 11. The sand and gravel are evenly distributed on a layer of filter plate 17. Soak them first. After soaking, prepare to start the cleaning operation. Start the rotating device 1 to make it rotate forward. The output end of the motor drives the driven shaft 2 to rotate forward, and then drives the follower shaft 7 to rotate forward. Due to the threaded connection relationship between the one-way thread 6 on the follower shaft 7 and the displacement sleeve 5, the displacement sleeve 5 starts to move downward. The displacement sleeve 5 drives the rinse basket 11 to move downward synchronously through the fixed rod 4. The sand and gravel in the rinse basket 11 are rinsed up and down in the water as the rinse basket 11 moves downward to preliminarily remove some impurities. When the sand and gravel need to be cleaned more finely, the rotating device 1 is reversed, the motor drives the driven shaft 2 to reverse, and the follower shaft 7 also reverses accordingly. The cylinder 5 moves upward, and the rinse tray cage 11 is lifted upward. At the same time, the driving gear 3 drives the driven gear 12 to rotate as the driven shaft 2 reverses, and the driven gear 12 drives the center rod 13 to rotate, and the three cleaning sleeves 15 on the center rod 13 rotate accordingly, thereby driving the three groups of first cleaning roller brushes 14 and second cleaning roller brushes 16 to rotate, and evenly roll and brush the sand and gravel on the first filter plate 17, the second filter plate 18 and the third filter plate 19, and further remove impurities in the sand and gravel, such as sand and gravel, mica, soil and clay, etc. The filter plates with different apertures play a role of layered filtration. The coarse pores of the first filter plate 17 filter sand and gravel, the fine pores of the second filter plate 18 filter mica, and the fine filtration of the third filter plate 19 is used to filter soil and clay. After multiple rinses and rolls, the cleanliness of the sand and gravel is improved;

[0066] S2. After the sand and gravel washing process reaches a certain stage or is completed, the control system 110 starts the sample collection unit, and the sampling bucket moves to a predetermined position (close to the rinse tray cage 11 or each layer of filter plate) through the electric track 122 to collect a certain amount of sand and gravel samples. The automatic weighing device 124 records the quality data of the collected samples and transmits the data to the control system 110 to ensure that the collected samples are representative and the quality data is accurate. The collected sand and gravel samples enter the transparent cylindrical dissolution tank 310 of the dissolution and stirring unit 300 through the pipeline 330 (the electric valve 340 on the pipeline 330 is opened), the feed inlet electric valve 340 is closed, a known volume of deionized water is added from the water inlet, and then the stirring paddle 350 and the heating device 360 ​​are started. The stirring paddle 350 stirs the solution at a certain speed, and the heating device 360 ​​heats the solution to room temperature so that the soluble impurities in the sand and gravel are fully dissolved in the water to form a uniform mixed solution to prepare for subsequent detection. After the stirring and heating process is completed, the static solution is allowed to stand for a period of time. time, so that the suspended particles in the solution are precipitated and stabilized, then, the high-precision conductivity sensor 410 of the conductivity detection module 400 and the turbidity sensor 510 of the turbidity detection module 500 respectively measure the solution, the conductivity sensor measures the conductivity value of the solution, and the turbidity sensor 510 measures the turbidity value of the solution, and the measurement data is transmitted to the data acquisition card 610 in real time, and the data acquisition card 610 transmits the received conductivity value and turbidity value to the computer control system 620, and the built-in data analysis module 640 of the computer control system 620 compares and analyzes the measurement value with the standard conductivity value range and turbidity value range of the washed sand and gravel pre-stored in the database. If the conductivity value and the turbidity value are both within the corresponding standard range, it is determined that the sand and gravel have been cleaned, and if any of the values ​​exceeds the standard range, it is determined that the sand and gravel do not meet the cleaning requirements and need to be further cleaned or the cleaning process is adjusted. The judgment result is intuitively displayed on the display screen 630, and the operator can take corresponding measures according to the displayed result;

[0067] S3. When the sand and gravel are cleaned and tested to meet the cleaning standards, the waterproof oven 21 inside the overflow bottom cover 22 is started. The wind blown out of the oven passes through each layer of filter plates upward to dry the sand and gravel on the filter plates. The oven continues to operate, and the wind takes away the moisture in the sand and gravel, so that the sand and gravel gradually dry. During the drying process, the sand and gravel can be turned over appropriately to speed up the drying speed and ensure that the sand and gravel reach the required degree of dryness for subsequent storage and use. When the sand and gravel are completely dry, the oven is closed, the cleaning barrel 10 is opened, the washed and dried sand and gravel are taken out, packaged or transported to the next production link, and the device is cleaned and maintained at the same time to prepare for the next sand and gravel washing operation;

[0068] S4. After the drying process is completed, ensure that the sand and gravel are in a stable state and prepare for weighing operations. The device is in a stopped state and all components are stationary. When the sand and gravel are in the rinse drawer cage 11, the automatic weighing device 124 measures the mass of the sand and gravel again, and transmits the data to the control system for recording and subsequent processing. The operator can also manually record the weighing data, complete the weighing and subsequent processing, and after recording the final mass of the sand and gravel, open the cleaning barrel 10, take out the sand and gravel that have been washed, dried and weighed, and package or transport them to the next production link according to actual needs. At the same time, clean and maintain the device to prepare for the next sand and gravel washing operation.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
