Description

Technical Field

[0001] This utility model relates to the field of material screening and cleaning technology, and in particular to an automatic adjustment device for water washing screen material. Background Technology

[0002] In traditional material washing and screening processes, the washing water volume is often fixed, making it impossible to adjust in real time based on the actual mud content of the material. When the mud content is high, a fixed washing water volume may result in incomplete cleaning, affecting the quality of the finished product; conversely, when the mud content is low, excessive washing water leads to water waste and increased subsequent processing costs. Furthermore, traditional systems lack effective recording and analysis of material conditions and washing process data, hindering precise and intelligent management.

[0003] Therefore, it is necessary to provide an automatic adjustment device for water-washed screen materials to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides an automatic adjustment device for water washing screen material, which solves the problems in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic adjustment device for washing and screening materials, including a fixed frame and a variable frequency water pump. A screen hopper body is mounted on the top surface of the fixed frame, and a discharge port is provided at one end of the screen hopper body. A visual image recognition system is mounted on the surface of the fixed frame on the side of the discharge port. The visual image recognition system consists of an image acquisition module, an image preprocessing module, a feature extraction and recognition module, a data analysis and decision-making module, and a data storage and management module. Its system operation steps are as follows: S1. Image Acquisition: An industrial camera, in conjunction with a lighting system, acquires real-time images of the finished product output from the washing screen. The acquired image data is transmitted to a computer or image processor via an image acquisition card.

[0006] S2. Image preprocessing: Perform preprocessing operations such as denoising, filtering, and enhancement on the acquired raw images to improve image quality and the accuracy of feature extraction.

[0007] S3. Feature Extraction and Recognition: Extract features related to material characteristics from the preprocessed image, and use image recognition algorithms to analyze and recognize these features to determine the proportion of irregular materials in the output.

[0008] S4. Compare the image recognition result with the preset threshold to determine the mud content of the material. If the proportion of irregular material exceeds the threshold, the mud content is deemed excessive, and the system sends an instruction to the variable frequency water pump to increase the water supply; if the proportion of irregular material is below the threshold, the mud content is deemed normal, and the system sends an instruction to the variable frequency water pump to decrease the water supply.

[0009] S5. Store image data, processing results, equipment operating parameters, and other information in a database, and manage and analyze them through data management software.

[0010] The core architecture and intelligent adjustment mechanism of the automatic adjustment device for water washing and screening. The screen bucket body installed on top of the fixed frame serves as the basic carrier for material washing and screening, providing a stable environment for subsequent operations. The introduction of a visual image and text recognition system is a key innovation. It consists of an image acquisition module, an image preprocessing module, a feature extraction and recognition module, a data analysis and decision-making module, and a data storage and management module, forming a complete system for monitoring and analyzing the mud content of materials. An industrial camera, in conjunction with a lighting system, acquires images of the discharged material in real time. After transmission via an image acquisition card, the image quality is improved through image preprocessing, the material characteristics are analyzed by the feature extraction and recognition module, and then the data analysis and decision-making module compares the recognition results with preset thresholds to accurately determine the mud content of the material and sends adjustment commands to the variable frequency water pump accordingly. This intelligent adjustment mechanism overcomes the shortcomings of traditional water washing and screening processes, which have a fixed water volume and cannot adapt to changes in material in real time. It can dynamically adjust the water volume according to the actual mud content of the material, ensuring the cleaning effect, improving the quality of the finished product, avoiding water waste, and improving production efficiency and resource utilization. Meanwhile, the data storage and management module records and analyzes information such as image data and processing results, providing data support for system optimization and production management, and helping to achieve precise and intelligent management of the water washing and screening process.

[0011] Preferably, a water tank is placed on one side of the mounting frame, and a variable frequency water pump is installed on the other side of the water tank. Water pipes are installed at both the output and input ends of the variable frequency water pump. The water pipe at the input end of the variable frequency water pump is connected to the water tank. A high-pressure nozzle is installed on the surface of the water pipe at the output end of the variable frequency water pump, located directly above the main body of the screen bucket, further improving the water supply and washing functions of the washing system. The water tank on one side of the mounting frame serves as a water source reserve, providing sufficient water resources for the washing process. The variable frequency water pump installed on one side of the water tank achieves directional water transmission through the water pipes at both the output and input ends. The water pipe at the input end of the variable frequency water pump is connected to the water tank, ensuring a stable water supply. The high-pressure nozzle installed on the surface of the water pipe at the output end is located directly above the main body of the screen bucket, enabling powerful rinsing of the material inside the screen bucket with high-pressure water flow, improving washing efficiency and ensuring that the material is thoroughly cleaned. The variable frequency water pump can change its speed according to the instructions of the visual graphic recognition system, thereby flexibly adjusting the water supply. This ensures that the washing process can meet the material cleaning needs while avoiding waste caused by excessive water volume. It achieves precise control and efficient utilization of the washing water volume, further improving the practicality and economy of the system.

[0012] Preferably, a drainage hopper is provided at the bottom of the screen hopper body. This drainage hopper serves as a crucial channel for wastewater discharge during the washing process. During material washing, wastewater carries mud, sand, and impurities washed off the material's surface. The drainage hopper promptly discharges this wastewater from the screen hopper body, preventing its accumulation and ensuring optimal washing and screening results. Its well-designed location ensures smooth wastewater flow, maintaining a clean internal environment for the screen hopper body. This guarantees continuous washing and efficient screening of materials, contributing to the stability and continuity of the entire washing and screening process.

[0013] Preferably, a collection box is installed inside the fixing frame below the drainage hopper. The collection box contains a filter screen, and a circulation pump is installed on the outer surface of the water tank. Both the output and input ends of the circulation pump are equipped with return pipes. The return pipe at the input end of the circulation pump is connected to the collection box. The collection box, filter screen, circulation pump, and return pipe together constitute the system's water resource recycling system. The collection box inside the fixing frame, located below the drainage hopper, collects the wastewater discharged from the drainage hopper. The filter screen inside the collection box performs preliminary filtration of silt, impurities, etc., in the wastewater, effectively intercepting large particulate pollutants and preventing them from entering the water tank and causing blockages or affecting water quality. The circulation pump outside the water tank is connected to the collection box via the return pipe, pumping the pre-filtered water back into the water tank, achieving water resource recycling. This design significantly reduces the consumption of fresh water, lowers the enterprise's dependence on water resources, reduces wastewater discharge, lowers subsequent wastewater treatment costs, meets environmental protection requirements, achieves a win-win situation for economic and environmental benefits, and further enhances the system's sustainability and competitiveness.

[0014] Preferably, a feeding mechanism is installed on one side of the fixed frame. This feeding mechanism plays a crucial role in conveying the material to be washed and screened to the main body of the screen hopper. Its stable and efficient feeding function ensures that the material continuously and evenly enters the main body of the screen hopper, providing a stable material supply for the washing and screening process and avoiding production interruptions or poor washing results due to untimely or uneven material delivery. The feeding mechanism, together with the main body of the screen hopper, the visual graphic recognition system, and other components, forms a continuous and efficient production process for the entire washing and screening system. This improves the system's automation level and production efficiency, reduces manual intervention costs, and enhances the enterprise's production management level.

[0015] Preferably, a controller is installed on the mounting frame. This controller is electrically connected to the visual image recognition system, the variable frequency water pump, and the circulating pump. As the "nerve center" of the entire system, the controller, through its electrical connection with these components, enables unified control and coordinated operation of all system components. The controller receives the material mud content judgment result transmitted by the visual image recognition system and sends instructions to the variable frequency water pump to adjust the water supply according to a preset program, ensuring that the washing water volume matches the material mud content. Simultaneously, the controller can control the start and stop of the circulating pump based on the washing process and water resource circulation requirements, achieving rational recycling of water resources. This centralized control method enables the system components to work collaboratively, achieving automated and intelligent operation of the washing and screening process. It improves the system's response speed and operational stability, facilitates monitoring and management of the entire system, reduces operational difficulty and management costs, and provides strong support for the precision and efficiency of the washing and screening process.

[0016] Compared with related technologies, the automatic adjustment device for water washing screen materials provided by this utility model has the following beneficial effects: Compared to existing technologies, the automatic adjustment device for water washing and screening achieves real-time monitoring and accurate judgment of the mud content of materials through a visual image and text recognition system. In traditional water washing and screening processes, the inability to adjust the washing water volume in real time leads to poor cleaning effects or resource waste. This system, however, utilizes a collaborative approach involving image acquisition, image preprocessing, and feature extraction and recognition modules to accurately analyze the proportion of irregular materials in the output, thereby determining the mud content. When the mud content exceeds the standard, the system automatically sends an instruction to the variable frequency water pump to increase the water supply, ensuring thorough cleaning of the material; when the mud content is normal, the system sends an instruction to reduce the water supply, avoiding water waste. This precise intelligent adjustment method effectively solves the drawbacks of traditional fixed washing water volumes, significantly improves finished product quality, increases production efficiency, and reduces rework costs caused by incomplete cleaning.

[0017] Compared to existing technologies, the automatic adjustment device for washing and screening materials comprises a water tank, a variable frequency water pump, a collection tank, and a circulation pump, all mounted on one side of the fixed frame, forming a complete water circulation system. Water pipes installed at the output and input ends of the variable frequency water pump, along with a high-pressure nozzle located directly above the screen hopper, achieve efficient material washing. A drain hopper at the bottom of the screen hopper discharges wastewater into the collection tank inside the fixed frame. A filter screen in the collection tank performs preliminary filtration of the wastewater. The return pipe at the input end of the circulation pump is connected to the collection tank, and the pre-filtered water is pumped back to the water tank, achieving water resource recycling. Compared to traditional washing and screening systems, this design significantly reduces the consumption of fresh water, lowers subsequent wastewater treatment costs, effectively conserves water resources, aligns with green production principles, and significantly reduces the company's operating costs.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] First embodiment: Please refer to the following: Figure 1-3 The automatic adjustment device for washing and screening materials includes a fixed frame 1 and a variable frequency water pump 11. A screen bucket body 5 is mounted on the top surface of the fixed frame 1. A discharge port 14 is provided at one end of the screen bucket body 5. A visual image recognition system 13 is mounted on the surface of the fixed frame 1 on the side of the discharge port 14. The visual image recognition system 13 consists of an image acquisition module, an image preprocessing module, a feature extraction and recognition module, a data analysis and decision-making module, and a data storage and management module. Its system operation steps are as follows: S1. Image Acquisition: An industrial camera, in conjunction with a lighting system, acquires real-time images of the finished product output from the washing screen. The acquired image data is transmitted to a computer or image processor via an image acquisition card.

[0023] S2. Image preprocessing: Perform preprocessing operations such as denoising, filtering, and enhancement on the acquired raw images to improve image quality and the accuracy of feature extraction.

[0024] S3. Feature Extraction and Recognition: Extract features related to material characteristics from the preprocessed image, and use image recognition algorithms to analyze and recognize these features to determine the proportion of irregular materials in the output.

[0025] S4. Compare the image recognition result with the preset threshold to determine the mud content of the material. If the proportion of irregular material exceeds the threshold, the mud content is determined to be excessive, and the system sends an instruction to the variable frequency water pump 11 to increase the water supply; if the proportion of irregular material is lower than the threshold, the mud content is determined to be normal, and the system sends an instruction to the variable frequency water pump 11 to decrease the water supply.

[0026] S5. Store image data, processing results, equipment operating parameters, and other information in a database, and manage and analyze them through data management software.

[0027] The core architecture and intelligent adjustment mechanism of the automatic adjustment device for water washing and screening. The screen bucket body 5, installed on top of the fixed frame 1, serves as the basic carrier for material washing and screening, providing a stable environment for subsequent operations. The introduction of the visual image and text recognition system 13 is a key innovation. It consists of an image acquisition module, an image preprocessing module, a feature extraction and recognition module, a data analysis and decision-making module, and a data storage and management module, forming a complete system for monitoring and analyzing the mud content of materials. An industrial camera, in conjunction with a lighting system, acquires images of the discharged material in real time. After transmission via an image acquisition card, the image quality is improved through image preprocessing, the material characteristics are analyzed by the feature extraction and recognition module, and then the data analysis and decision-making module compares the recognition results with preset thresholds to accurately determine the mud content of the material and sends adjustment commands to the variable frequency water pump 11 accordingly. This intelligent adjustment mechanism overcomes the shortcomings of traditional water washing and screening processes, which have fixed water volume and cannot adapt to changes in materials in real time. It can dynamically adjust the water volume according to the actual mud content of the material, ensuring the cleaning effect of the material, improving the quality of the finished product, avoiding water waste, and improving production efficiency and resource utilization. Meanwhile, the data storage and management module records and analyzes image data, processing results, and other information, providing data support for system optimization and production management, and helping to achieve precise and intelligent management of the washing and screening process. The working principle of the automatic adjustment device for water washing screen material provided by this utility model is as follows: The feeding mechanism 4 conveys the material to be washed and screened into the screen hopper body 5 on the top surface of the fixed frame 1. At this time, the industrial camera in the visual image recognition system 13, with the assistance of the lighting system, begins to acquire real-time images of the finished product output from the washing and screening system. The acquired image data is transmitted to a computer or image processor via an image acquisition card, and then enters the image preprocessing stage, where noise reduction, filtering, and enhancement operations are performed on the original image to improve image quality and the accuracy of subsequent feature extraction. After preprocessing, the system extracts material-related features from the image using a feature extraction and recognition module, and analyzes and identifies these features using an image recognition algorithm to determine the proportion of irregular materials in the output. Next, the image recognition results are compared with preset thresholds to determine the mud content of the material. If the proportion of irregular materials exceeds the threshold, the mud content is deemed excessive, and the controller 12 sends an instruction to the variable frequency water pump 11 to increase the water supply. The variable frequency water pump 11 increases its speed, increasing the water supply from the water tank 10 to the high-pressure nozzle 6, which then washes the material in the screen hopper 5 with higher water pressure. If the proportion of irregular materials is below the threshold, the mud content is deemed normal, and the controller 12 sends an instruction to the variable frequency water pump 11 to decrease the water supply. The variable frequency water pump 11 then reduces its speed and water supply.

[0028] During the washing process, the wastewater in the screen body 5 flows into the collection box 2 located below the drainage hopper 3 inside the fixed frame 1. The filter screen 15 inside the collection box 2 intercepts and filters impurities in the wastewater. The circulation pump 9 installed on the outer surface of the water tank 10 is started under the control of the controller 12. The circulation pump 9 pumps the pre-filtered water in the collection box 2 back to the water tank 10 through the return pipe 8 at the input end, realizing the recycling of water resources and providing a water source for the next washing. Throughout the process, the visual image and text recognition system 13 stores image data, processing results, equipment operating parameters and other information into the database, and manages and analyzes them through data management software, which facilitates staff to monitor and optimize the water washing and screening process, and realizes precise and intelligent management of the water washing and screening process.

[0029] Compared with related technologies, the automatic adjustment device for water washing screen materials provided by this utility model has the following beneficial effects: The automatic adjustment device for washing and screening materials uses a visual image and text recognition system 13 to achieve real-time monitoring and accurate judgment of the mud content of materials. In traditional washing and screening processes, the inability to adjust the washing water volume in real time leads to poor cleaning effects or waste of resources. However, the image acquisition module, image preprocessing module, feature extraction and recognition module of this system work together to accurately analyze the proportion of irregular materials in the output, thereby judging the mud content of the material. When the mud content exceeds the standard, the system automatically sends an instruction to the variable frequency water pump 11 to increase the water supply to ensure that the material is thoroughly cleaned; when the mud content is normal, the system sends an instruction to reduce the water supply to avoid water waste. This precise intelligent adjustment method effectively solves the drawbacks of traditional fixed washing water volume, significantly improves the quality of finished products, increases production efficiency, and reduces rework costs caused by incomplete cleaning. Furthermore, the water tank 10, variable frequency water pump 11, collection tank 2, circulation pump 9, and other components placed on one side of the fixed frame 1 constitute a complete water circulation system. Water pipes 7 installed at the output and input ends of the variable frequency water pump 11, in conjunction with a high-pressure nozzle 6 located directly above the screen hopper body 5, achieve efficient washing of materials. The drain hopper 3 at the bottom of the screen hopper body 5 discharges wastewater into a collection box 2 inside the fixed frame 1. A filter screen 15 inside the collection box 2 performs preliminary filtration of the wastewater. The return pipe 8 at the input end of the circulating pump 9 is connected to the collection box 2, and the pre-filtered water is pumped back to the water tank 10 by the circulating pump 9, achieving water resource recycling. Compared to traditional water washing and screening systems, this design significantly reduces the amount of fresh water used, lowers subsequent wastewater treatment costs, effectively saves water resources, conforms to the concept of green production, and significantly reduces the company's operating costs.

The water pipe 7 at the input end of the variable frequency water pump 11 is connected to the water tank 10. A high-pressure nozzle 6 is installed on the surface of the water pipe 7 at the output end of the variable frequency water pump 11, located directly above the screen bucket body 5, further improving the water supply and washing functions of the washing system. The water tank 10 on one side of the mounting frame 1 serves as a water source reserve, providing sufficient water resources for the washing process. The variable frequency water pump 11, installed on one side of the water tank 10, achieves directional water transmission through the water pipes 7 at both the output and input ends. The water pipe 7 at the input end of the variable frequency water pump 11 is connected to the water tank 10, ensuring a stable water supply.

The variable frequency water pump 11 can change its speed according to the instructions of the visual graphic recognition system 13, thereby flexibly adjusting the water supply. This ensures that the washing process can meet the material cleaning needs while avoiding waste caused by excessive water volume.

The collection box 2, located below the drainage hopper 3 inside the fixed frame 1, collects the wastewater discharged from the drainage hopper 3. The filter screen 15 inside the collection box 2 performs preliminary filtration of silt, impurities, and other contaminants in the wastewater, effectively intercepting large particulate pollutants and preventing them from entering the water tank 10 and causing blockages or affecting water quality. The circulation pump 9 on the outside of the water tank 10 is connected to the collection box 2 via the return pipe 8, pumping the pre-filtered water back into the water tank 10, thus realizing the recycling of water resources. This design significantly reduces the amount of fresh water used, lowers the company's dependence on water resources, reduces wastewater discharge, lowers subsequent wastewater treatment costs, meets environmental protection requirements, achieves a win-win situation for both economic and environmental benefits, and further enhances the system's sustainability and competitiveness.

This improves the system's automation level and production efficiency, reduces manual intervention costs, and enhances the company's production management level.

[0035] Based on Example 1, see [link / reference] Figure 1-3A controller 12 is installed on the mounting frame 1. The controller 12 is electrically connected to the visual image recognition system 13, the variable frequency water pump 11, and the circulating pump 9.
