Description

Technical Field

[0001] This invention relates generally to the technical field of ore crushing and sand making, and more specifically to a dry-wet separation crushing production system, method and storage medium. Background Technology

[0002] Sand and gravel are widely used as essential raw materials for construction, roads, and infrastructure. In mining enterprises, raw ore undergoes coarse crushing, fine crushing, and shaping processes after being extracted from the mine. In existing technologies, sludge from the sand and gravel raw materials is carried throughout the entire crushing production line. During each crushing stage, water is used for washing, and the sludge, along with dust generated during crushing, is collected and piped into a wastewater treatment pond. It then undergoes multiple processes including wastewater collection, multi-stage sedimentation, addition of flocculants, and filter pressing to form cakes. The main problems with this water-based sand production process are as follows:

[0003] (1) Increased investment costs and production and operation costs.

[0004] If the sludge on the surface of the ore raw material can be separated before crushing, it can be discharged or recycled without special treatment because the sludge is only mud and not a mixture of sludge and mineral powder. However, the water-based sand making process produces a mixture of sludge and mineral powder, which cannot be directly discharged or recycled. Therefore, a "wastewater treatment system" needs to be added to the crushing production line, which complicates the process flow of the sand making production line and significantly increases the equipment investment cost; at the same time, the production and operating costs are also greatly increased.

[0005] (2) The resources of the "mineral powder" products generated during the crushing process are wasted.

[0006] Each stage of stone crushing produces "mineral powder." After being washed by a spraying device, this mineral powder is washed into a sewage pond along with the mud bricks. The "fine powder mixed with sludge" cannot be extracted separately. Finally, it is pressed into "mud cakes" along with the mud bricks and discarded as waste, resulting in a large waste of resources and a significant reduction in the economic benefits for investors.

[0007] (3) New sources of pollution, such as “sewage”, have been generated.

[0008] Although the wastewater treated by the wastewater treatment system meets the environmental discharge requirements, it cannot completely purify the water and will cause pollution to the environment to some extent. Therefore, in addition to the dust pollution source that cannot be completely avoided, the manufactured sand and gravel crushing production line has an additional source of wastewater pollution.

[0009] Therefore, it is very important to complete the "sludge removal process" before the raw materials enter the crushing production line, that is, to solve the sludge problem at the source of the crushing production line so that clean raw materials can directly enter the crushing production line and meet the requirements of the new "dry sand making" process. Summary of the Invention

[0010] In order to realize the dry-wet separation crushing production process and solve the problem of sludge and mineral powder being mixed together, this application provides a dry-wet separation crushing production system, method and storage medium.

[0011] In a first aspect, this application provides a dry-wet separation crushing production system, comprising:

[0012] The sludge pre-separation module is used to separate the sludge on the surface of the ore masterbatch from the ore surface, and to make the stripped sludge flow into the sludge treatment module in a unified manner.

[0013] The sludge detection module is used to detect whether the sludge on the surface of the ore formed by the sludge pre-separation module has been cleaned up to standard. If it is up to standard, it flows into the next process; if it is not up to standard, it is returned to the sludge pre-separation module for processing.

[0014] The dry sand making module is used to crush ore that has passed the sludge testing module and collect the dust generated during the sand making process for recycling.

[0015] The sludge pre-separation module is physically isolated from the dry sand making module. The sludge detection module is located between the sludge pre-separation module and the dry sand making module, and includes a detection mechanism and a sorting mechanism that separates the unqualified products identified by the detection mechanism from the qualified products.

[0016] Furthermore, the sludge pre-separation module includes a feeding mechanism and a sludge cleaning mechanism. The feeding mechanism is used to transport the fed masterbatch to the sludge cleaning mechanism and to transport the ore cleaned by the sludge cleaning mechanism to the dry sand making module. The sludge cleaning mechanism is used to separate the sludge on the surface of the ore masterbatch from the ore surface. The sludge pre-separation module also includes a sludge treatment module for collecting and treating wastewater.

[0017] Furthermore, the sludge cleaning mechanism includes at least one stage of ultrasonic cleaning system. The ultrasonic cleaning system includes a cleaning tank, an ultrasonic generator, a transducer, and a circulating filtration system. The ultrasonic generator generates high-frequency current and converts it into mechanical vibration. The transducer generates high-frequency mechanical vibration after receiving a high-frequency AC signal, converting electrical energy into mechanical energy. The circulating filtration system includes a circulating pump and a filter, which allows the cleaning liquid to circulate in the cleaning tank and to uniformly flow the sludge into the sludge treatment module.

[0018] Furthermore, the detection mechanism includes a first detection mechanism and a second detection mechanism, which are disposed above the feeding mechanism. The corresponding feeding mechanism is provided with a first sorting mechanism and a second sorting mechanism, which are used to separate the non-conforming products identified by the detection mechanism from the conforming products. The sorting mechanism is provided with a beveled surface and a flat surface, and a protrusion is provided at the junction of the beveled surface and the flat surface.

[0019] Furthermore, a return material mechanism is provided below the first and second sorting mechanisms. One end of the return material mechanism is connected to the sorting mechanism via a funnel, and the other end is connected to the feeding mechanism. This mechanism is used to return the defective products separated by the sorting mechanism to the sludge pretreatment module for processing.

[0020] Furthermore, the detection mechanism includes at least one detection camera for image acquisition, and a central processing unit for processing images acquired in real time by the detection camera and issuing instructions to the sorting mechanism based on the images, the central processing unit including a deep learning model.

[0021] Furthermore, the dry sand making module includes a crushing unit for crushing and shaping ore, an isolation device surrounding the crushing unit to form a closed space, and a collection device installed on the isolation device for collecting dust. The collection device includes a blower, a vacuum cleaner, and a collection container, as well as a pipe connecting the vacuum cleaner and the collection container. The blower is installed on both sides of the isolation device to form an upward airflow, and the vacuum cleaner is installed on the top of the collection device to absorb the dust blown by the blower.

[0022] Secondly, this application provides a dry-wet separation crushing production method, which is executed by one or more processors executing a computer program, the method comprising:

[0023] S601: Masterbatch feeding, the feeding mechanism transports the fed masterbatch to the sludge cleaning mechanism;

[0024] S602: Sludge pre-separation. The sludge cleaning mechanism is used to separate the sludge from the surface of the ore masterbatch. The cleaned ore is fed into the dry sand making module through the feeding mechanism. The separated sludge is uniformly collected into the sludge treatment module.

[0025] S603: Sludge detection. The first and second detection mechanisms respectively collect images of the first and second ore and input them into the central processing unit. The central processing unit compares and analyzes the images with the images in the defect database. If the images are qualified, they flow into the next process. If they are unqualified, the central processing unit issues an instruction to open the first or second sorting mechanism. The unqualified products fall into the return mechanism and are returned to the sludge pretreatment module.

[0026] S604: Dry sand making. Qualified ore is fed into the crushing module and crushed into sand and gravel through primary, secondary and tertiary crushing. The dust generated in this process is collected in a collection container by blowers, vacuum cleaners and pipelines for recycling.

[0027] S605: Storage or transportation, where the finished sand and gravel are transported by conveyor to the finished product warehouse for storage, or directly by conveyor to the logistics vehicle for shipment.

[0028] Furthermore, the specific steps for sludge detection are as follows:

[0029] S801: Acquires ore images, detects the camera to acquire various ore images under different positions and different light intensities, including images of qualified and unqualified products;

[0030] S802: Training the central processing unit, based on images of qualified and unqualified products captured by the inspection camera, to train the central processing unit and extract a defect image library;

[0031] S803: Determine whether the current image is qualified. Use the trained central processing unit to analyze the current image captured by the detection camera, compare and analyze the current image with the defect image library, and determine whether the current image belongs to the defect image library. If it does, it is a defective product; otherwise, it is a qualified product.

[0032] S804: Generate instruction. Based on the comparison and analysis between the current image and the defect image library, if the result is unqualified, issue an instruction to open the sorting mechanism; if the result is qualified, issue an instruction to close the sorting mechanism.

[0033] Thirdly, this application provides a non-transitory computer-readable medium including instructions for use in dry-wet separation crushing production, wherein when executed by one or more processors, the instructions cause the one or more processors to perform the method described in any of the second aspects.

[0034] Compared with the prior art, the present invention has the following technical effects:

[0035] 1. It reduces investment and production operating costs. By separating surface sludge before ore crushing, it solves the sludge removal problem at the source of the stone, ensuring that the stone entering the crushing production line is in a state with little or no sludge that meets national standards. This overcomes the bottleneck for realizing the new dry sand making crushing process, eliminating the need for investment in "sludge removal" equipment in the sand making production line, that is, eliminating the need for spray sludge removal system and sewage treatment system. It simplifies the process flow and equipment resources of the sand making production line, and reduces the investment and production costs of the sand making production line.

[0036] 2. It solves the problem of wasted "mineral powder" resources generated during the crushing process. The dry sand making process is completed in a closed space, and the dust and noise generated during the operation are confined to the closed space, preventing dust and noise pollution. In addition, the dust settles in the closed space or is directly collected in a container by dust collection equipment, realizing recycling and reuse, saving resources and generating beneficial economic benefits.

[0037] 3. It solves the problem of new pollution sources such as "sewage" generated during the sand making process, enabling the sand making production line to achieve dry sand making. No water source is involved in the entire crushing process, so there is no water pollution problem. Wastewater is generated during the sludge pre-separation process. Since the sludge at this time is only composed of mud, rather than a mixture of sludge and mineral powder, it can be discharged or recycled without special treatment, thus realizing the beneficial value of energy saving and environmental protection.

[0053] refer to Figure 1This paper illustrates a dry-wet separation crushing production system, comprising: a sludge pre-separation module 101, used to separate sludge from the surface of ore raw materials and allow the stripped sludge to flow into a sludge treatment module; a sludge detection module 102, used to detect whether the sludge on the ore surface formed by the sludge pre-separation module is cleaned up to standard; if it is qualified, it flows into the next process; if it is unqualified, it is returned to the sludge pre-separation module for processing; and a dry sand making module 103, used to crush the ore that has passed the sludge detection module and collect the dust generated during the sand making process for recycling.

[0054] The sludge pre-separation module 101 is physically isolated from the dry sand making module 103 and operates independently. The sludge pre-separation module 101 uses a water-based method to separate sludge from the surface of the ore masterbatch. The dry sand making module 103 operates entirely in a dry environment without the use of water, thus achieving dry-wet separation. The sludge pre-separation module 101 includes a feeding mechanism and a sludge cleaning mechanism. The feeding mechanism transports the fed masterbatch to the sludge cleaning mechanism and transports the ore cleaned by the sludge cleaning mechanism to the dry sand making module 103. The sludge cleaning mechanism separates the sludge from the surface of the ore masterbatch. It should be noted that the sludge pre-separation module 101 also includes a sludge treatment module for collecting and treating wastewater. The sludge treatment module can be located in the same area as the feeding mechanism and the sludge cleaning mechanism, saving floor space, or it can be independently located in another part of the production line for convenient operation. Compared to the wastewater treatment systems in existing sand-making production lines, the sludge treatment module of this invention only needs to treat the sludge on the surface of the masterbatch, while existing wastewater treatment systems need to treat a mixture of sludge and mineral powder. Therefore, the process flow and cost of the sludge treatment module are significantly reduced. The process flow of existing wastewater treatment systems is as follows: "1. Separation of wastewater and sand + 2. Wastewater undergoes multi-stage sedimentation / simultaneous addition of coagulant + 3. Sludge is pressed into cakes + 4. Filtered water is returned for reuse." Furthermore, the sludge collected by this invention is pure sludge because it does not contain mineral powder. Therefore, theoretically, it can be directly discharged or discharged after simple treatment, while the sludge cake obtained by existing filtration technology cannot be directly discharged because it contains chemicals.

[0055] The sludge cleaning mechanism includes at least one stage of ultrasonic cleaning system, preferably two stages. The first stage is used for initial sludge separation, and the second stage is used for further cleaning and separation of residual sludge. It should be noted that more stages of ultrasonic cleaning system can be set up according to cleaning needs until the optimal cleaning effect is achieved. The ultrasonic cleaning system includes a cleaning tank, an ultrasonic generator, a transducer, and a circulating filtration system. The ultrasonic generator generates high-frequency current and converts it into mechanical vibration; the transducer generates high-frequency mechanical vibration after receiving a high-frequency AC signal, converting electrical energy into mechanical energy; the circulating filtration system includes a circulating pump and a filter, which allows the cleaning solution to circulate within the cleaning tank and to uniformly flow the sludge into the sludge treatment module. It should be noted that the ultrasonic cleaning system used in this invention is only an example; high-pressure water jet rinsing, spraying, or drum circulation cleaning techniques can also be used. These techniques can also be combined; for example, the first stage of cleaning uses high-pressure water jet rinsing and spraying, and the second stage uses ultrasonic cleaning, or the first stage uses drum circulation cleaning and the second stage uses ultrasonic cleaning, or vice versa.

[0056] In operation, the ore masterbatch is vibrated and conveyed to the sludge cleaning unit via a feeding mechanism. Under the cleaning of at least one stage of ultrasonic cleaning system, sludge separation is achieved, resulting in clean ore. Therefore, subsequent processes do not require water-based sludge cleaning, creating conditions for dry sand production. After sludge separation, it flows into the sludge treatment module along with the wastewater, or is discharged directly after simple treatment or without treatment.

[0057] Continue to refer to Figure 2 and Figure 3 The sludge detection module 102 is located between the sludge pre-separation module and the dry sand making module. It includes a detection mechanism and a sorting mechanism that separates defective products identified by the detection mechanism from the qualified products. The detection mechanism includes a first detection mechanism and a second detection mechanism, located above the feeding mechanism. The corresponding feeding mechanism has a first sorting mechanism 202 and a second sorting mechanism 203, used to separate defective products identified by the detection mechanism from the qualified products. The first detection mechanism is used to acquire a first ore image, and the second detection mechanism is used to acquire a second ore image. This design aims to prevent the module from acquiring images from only one fixed angle if there is only one detection mechanism, thus reducing its accuracy and failing to accurately identify uncleaned ore. It should be noted that the first sorting mechanism 202 and the second sorting mechanism 203 are paired. Each sorting mechanism includes two symmetrically arranged mechanisms that can be opened or closed. The power for opening or closing can come from hydraulic pressure, pneumatic pressure, or other sources.

[0058] The sorting mechanisms 202 and 203 are provided with inclined surfaces 2021 and 2031 and flat surfaces 2023 and 2033. Protrusions 2022 and 2032 are provided at the junctions of the inclined surfaces 2021 and 2031 and the flat surfaces 2023 and 2033. The purpose of this design is that when the ore passes through the inclined surfaces 2021 and 2031, it will roll rapidly, temporarily creating a certain distance from the ore behind it, and eventually pass through the protrusions 2022 and 2032 and stop at the flat surfaces 2023 and 2033. At this point, the ore is in a stable state under the constraint of the protrusions 2022 and 2032 on both sides, facilitating image acquisition by the detection camera. In order to acquire images of the same ore from different angles, a second sorting mechanism 203 was designed. After the ore is imaged at the first sorting mechanism 202, the ore behind it rolls down from the inclined surfaces 2021 and 2031, pushing the ore on the flat surfaces 2023 and 2033 forward. The action at the second sorting mechanism 203 is repeated at the first sorting mechanism 202, except that the ore has been rotated 180° after rolling. Therefore, the second detection mechanism can acquire an image of the ore from another angle. Thus, the two images constitute complete information about the ore, thereby ensuring the accuracy of the detection mechanism.

[0059] Below the first and second sorting mechanisms is a return mechanism. One end of the return mechanism is connected to the sorting mechanism via a funnel, and the other end is connected to the feeding mechanism. It is used to return the unqualified products separated by the sorting mechanism to the sludge pretreatment module for processing.

[0060] In operation, the ore feedstock is vibrated and conveyed to the sludge cleaning mechanism via the feeding mechanism. After being cleaned by at least one stage of ultrasonic cleaning system, it flows into the sludge detection module. It then stops at the first sorting mechanism 202, where the first detection mechanism captures an image of the first ore. Subsequently, the ore continues to move to the second sorting mechanism 203, where the second detection mechanism captures an image of the second ore, thus forming a complete image of the ore. The detection mechanism determines whether the cleaned ore meets the cleanliness standard. If the first detection mechanism determines that it meets the standard, it continues to the next process. If it does not meet the standard, the ore is screened by the first sorting mechanism 202 and sent to the return mechanism. It then returns to the feeding mechanism via a pipeline, and is vibrated and conveyed to the sludge cleaning mechanism for re-cleaning. The second detection mechanism performs the same action, repeating this process to ensure that the ore conveyed to the dry sand making module is always clean.

[0061] The inspection mechanism includes at least one inspection camera for image acquisition, preferably three, respectively positioned on both sides and top of the ore to achieve omnidirectional inspection of the ore's surface condition and improve inspection accuracy. The inspection mechanism also includes a central processing unit that processes the images acquired in real-time by the inspection cameras and issues instructions to the sorting mechanism based on these images. In operation, the inspection cameras acquire images of the ore in real-time and transmit them to the central processing unit. The unit analyzes and determines whether the surface mud and sand of the ore is clean. If it is clean, it continues to the next process; otherwise, it is sorted by the sorting mechanism and sent to the return material mechanism, then returned to the feeding mechanism via a pipeline, and finally vibrated and conveyed to the sludge cleaning mechanism for re-washing. This process is repeated to ensure that all ore delivered to the dry sand making module is clean.

[0062] Continue to refer to Figure 4 and Figure 5 The dry sand making module 103 includes a crushing unit for crushing and shaping ore, an isolation device 401 surrounding the crushing unit to form a closed space, and a collection device installed on the isolation device for collecting dust. The crushing unit includes all the crushers involved in the crushing process, such as a jaw crusher for primary crushing, a cone crusher for secondary crushing, and a vertical impact crusher for tertiary crushing, etc. These devices are completely within the isolation device, isolated and independent from the sludge pre-separation module. Wastewater from the sludge pre-separation module is isolated from the dry sand making module and cannot mix into it. The dry sand making module itself does not require the use of water methods, thus achieving true dry and wet separation sand making. The collection device is equipped with a blower 402 and a dust collector 403. Preferably, the blowers 402 are arranged in pairs on both sides of the isolation device 401. The purpose of this design is that the blowers 402 blow air from both sides simultaneously, and the airflow meets in the middle and moves upward, thus forming an upward airflow. Under the drive of the upward airflow, the mineral powder quickly gathers upward, facilitating recovery. It is evident that the blower 402 serves two purposes: firstly, to accelerate airflow and increase the circulation of mineral powder; and secondly, to create an upward airflow that rapidly gathers the mineral powder upwards. The vacuum cleaner 403, located at the top of the collection device, can quickly recover the upward-gathering mineral powder, significantly improving vacuuming efficiency. Furthermore, the collection device includes a collection container for storing the mineral powder, and a pipe connecting the vacuum cleaner 403 and the collection container. During operation, clean ore is vibrated and conveyed to the crushing unit, where it undergoes primary, secondary, and tertiary crushing to produce sand and gravel. The mineral powder generated during this process is rapidly gathered upwards by the convection current created by the blowers on both sides, efficiently absorbed by the vacuum cleaner, and stored in the collection container for easy recycling.

[0063] Continue to refer to Figure 6 This application also provides a dry-wet separation crushing production method, which is executed by one or more processors executing a computer program, the method comprising:

[0064] S601: Masterbatch feeding, the feeding mechanism transports the fed masterbatch to the sludge cleaning mechanism;

[0065] S602: Sludge pre-separation. The sludge cleaning mechanism is used to separate the sludge from the surface of the ore masterbatch. The cleaned ore is fed into the dry sand making module through the feeding mechanism. The separated sludge is uniformly collected into the sludge treatment module.

[0066] S603: Sludge detection. The first and second detection mechanisms respectively collect images of the first and second ore and input them into the central processing unit. The central processing unit compares and analyzes the images with the images in the defect database. If the images are qualified, they flow into the next process. If they are unqualified, the central processing unit issues an instruction to open the first or second sorting mechanism. The unqualified products fall into the return mechanism and are returned to the sludge pretreatment module.

[0067] S604: Dry sand making. Qualified ore is fed into the crushing module and crushed into sand and gravel through primary, secondary and tertiary crushing. The dust generated in this process is collected in a collection container by blowers, vacuum cleaners and pipelines for recycling.

[0068] S605: Storage or transportation, where the finished sand and gravel are transported by conveyor to the finished product warehouse for storage, or directly by conveyor to the logistics vehicle for shipment.

[0069] The feeding of masterbatch is achieved by a feeding mechanism, the pre-separation of sludge is achieved by a pre-separation mechanism, the detection of sludge is achieved by a sludge detection module, and the dry sand making is achieved by a dry sand making module.

[0070] To achieve efficient sludge identification and improve detection accuracy, deep learning models can be introduced, such as random forests, which reduce the impact of noise through voting among multiple decision trees; gradient boosting trees, which automatically handle noise and support missing values ​​and distributed computation; adaptive weighting mechanisms, which dynamically reduce the weight of noisy samples; and Transformer architectures, which focus on key information through self-attention mechanisms. This application uses Long Short-Term Memory (LSTM) RNNs as an example.

[0071] refer to Figure 7Long Short-Term Memory (LSTM) RNNs, compared to ordinary Recurrent Neural Networks (RNNs), introduce memory units to store important information, and a series of gate control mechanisms (input gate, forget gate, output gate) to control the storage, forgetting, and output of information. This design allows LSTMs to remember key information in a data sequence while ignoring invalid data, resulting in relatively accurate predictions. The forget gate receives the current input and the hidden state from the previous time step, generating a vector between 0 and 1 using the sigmoid function, representing the proportion of forgetting. This result is multiplied by the state of the memory unit, thus achieving selective forgetting. The calculation formula is as follows:

[0072] f t =σ(W f ·[h t-1 ,x t ]+b t )

[0073] Among them, f t It is the output of the Forgotten Gate, W f It is the weight matrix of the forget gate, h t-1 It is the hidden state of the previous time step, x t It is the input for the current time step, b f σ is the bias vector of the forget gate, and σ is the sigmoid activation function that restricts the value to between 0 and 1.

[0074] To improve model training performance, feature objects typically need to be normalized or standardized. This eliminates the influence of differences in units and scales between features, treating each feature dimension equally. Next, a sliding window of samples needs to be constructed, including feature data and label data. The feature data is used to calculate the label data, which represents the prediction target. After this data processing, the LSTM model is built and trained. The input is the feature data from the past N time steps, and the output is the predicted value for the current time step. After training, the model can be used to predict the value at each time step, and the residual between the predicted and actual values, i.e., the error, is calculated. For normal data, the error should be small, while the error at outliers will be larger.

[0075] Therefore, a loss function is introduced as an evaluation metric for LSTM neural network models to measure the difference or error between the output of the first neural network model and the true label. The loss function is typically a non-negative real function, denoted as L(Y,f(X)), where Y is the actual value, f(X) is the model's predicted value, and X is the input data. The smaller the value of the loss function, the closer the model's prediction is to the actual value, and the better the model's performance. For regression tasks, the mean squared error (MSE) is often used as the loss function, calculated as follows:

[0076]

[0077] Where n is the number of samples, y i It is the actual value of the i-th sample. It is the predicted value of the i-th sample.

[0078] After setting up the LSTM model and loss function, the input data can be divided into training and testing data in a 7:3 ratio. In this application, the input feature object is historically collected images of cleaned ore. After training the neural network model, it can predict the current ore image. The SOFTMAX function is used to implement a binary classification problem, determining whether the ore is qualified or unqualified, and generating instructions to open or close the sorting mechanism accordingly.

[0079] Continue to refer to Figure 8 The specific steps for sludge testing are as follows:

[0080] S801: Acquires ore images, detects the camera to acquire various ore images under different positions and different light intensities, including images of qualified and unqualified products;

[0081] S802: Training the central processing unit, based on images of qualified and unqualified products captured by the inspection camera, to train the central processing unit and extract a defect image library;

[0082] S803: Determine whether the current image is qualified. Use the trained central processing unit to analyze the current image captured by the detection camera, compare and analyze the current image with the defect image library, and determine whether the current image belongs to the defect image library. If it does, it is a defective product; otherwise, it is a qualified product.

[0083] S804: Generate instruction. Based on the comparison and analysis between the current image and the defect image library, if the result is unqualified, issue an instruction to open the sorting mechanism; if the result is qualified, issue an instruction to close the sorting mechanism.

[0084] The functional modules in the embodiments of this application can be integrated together to form an independent part, or each module can exist independently, or two or more modules can be integrated to form an independent part. If the function is implemented as a software functional module and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, or part of the technical solution, can be embodied in the form of a software product.
