Description

Technical Field

Background Technology

[0002] Shallow medium separators are currently the most widely used coal heavy medium lump coal separation equipment, applied for high-precision separation of coking coal and thermal coal lump coal products. The shallow medium separator utilizes magnetite powder and coal slime to form a heavy medium with a certain density. Based on Archimedes' principle, after the raw coal enters the separator, it mixes with the heavy medium suspension. Through the action of upward and horizontal flow, it separates into clean coal and gangue according to density. During the use of the shallow medium separator, if coarse coal particles are mixed into the medium, or if the suspension has a high density or high viscosity, blockages may occur in the pipelines (such as the upward flow pipes and rising funnels) of the heavy medium separator during shutdown or operation.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] The blockage and unblocking mechanisms caused by coarse particles and fine sludge are different. Traditional methods mainly rely on high-pressure air to agitate the medium, which only serves an agitation function and cannot simultaneously address both coarse particle blockage and fine sludge accumulation, resulting in poor unblocking capabilities. Therefore, there is currently no efficient solution to the problem of pipeline blockage affecting production in shallow trough heavy media separators, and there is an urgent need for a device and method for preventing and controlling pipeline blockage in shallow trough heavy media separators.

[0027] As described in the background section, blockages occur in the pipelines of the existing heavy medium shallow tank separator. To solve the above problem, the embodiments of this application provide a pipeline unblocking system for a heavy medium shallow tank separator, a control method for the pipeline unblocking system, and a control device for the pipeline unblocking system.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] This application provides a pipeline unblocking system for a shallow trench separator for heavy media, such as... Figure 1 As shown, it includes:

[0030] The blockage detection subsystem 10 is located in the heavy medium shallow tank separator. The blockage detection subsystem is used to collect the blockage parameters of the heavy medium shallow tank separator and determine whether the pipeline of the heavy medium shallow tank separator is blocked based on the blockage parameters. The blockage parameters include one or more of the capacitance parameters and the flow parameters.

[0031] The blockage clearing subsystem 20 is communicatively connected to the blockage detection subsystem. The blockage clearing subsystem is located in the heavy medium shallow tank separator. The blockage clearing subsystem is used to clear the blockage when the blockage occurs in the pipeline of the heavy medium shallow tank separator. The clearing method includes one or more of electromagnetic clearing and resonance clearing.

[0032] In the above system, the presence of blockages in the pipeline is determined by detecting the capacitance and / or flow rate. If a blockage is found, electromagnetic and / or resonant methods can be used to clear the blockage, thus eliminating the blockage in the pipeline.

[0033] Specifically, electromagnetic dredging refers to using electromagnetic force to drive magnetic materials to reciprocate and clear sludge, while resonance dredging refers to using mechanical resonance to break up blockages.

[0034] Specifically, the blockage clearing subsystem includes an electromagnetic clearing device and a vibration clearing device installed along the pipeline, with the electromagnetic clearing device comprising multiple electromagnets.

[0035] In practical applications, a blockage detection subsystem and a blockage clearing subsystem can be installed along the outer wall of the rising medium flow pipeline and at the funnel of the heavy medium shallow trough separator.

[0036] In the specific implementation scheme, the blockage detection subsystem includes a capacitance tomography device and a first data analysis device. The capacitance tomography device is used to collect the capacitance value in the pipeline of the heavy medium shallow tank sorter. The first data analysis device is communicatively connected to the capacitance tomography device. The first data analysis device is used to reconstruct the pipeline image of the heavy medium shallow tank sorter based on the capacitance value using capacitance imaging technology, and to determine whether the pipeline is blocked based on the pipeline image.

[0037] In this scheme, capacitance signals (capacitance values) in the pipeline can be collected by a capacitance tomography device, and the capacitance signals can be analyzed and processed by a first data analysis device. Then, capacitance imaging technology can be used to more accurately determine whether the pipeline is blocked.

[0038] Specifically, the composition and distribution characteristics of the blockage can be determined by analyzing the capacitance signal. These distribution characteristics include the content of magnetic materials, coal slime, and coal particles.

[0039] Specifically, the capacitance tomography device may include a capacitance sensor, which is arranged on the outer tube wall to transmit and receive detection signals to obtain the capacitance value distribution. The data is then processed and analyzed to complete image reconstruction, determine the blockage situation, and output key parameters such as magnetic material content, coal slime content, large particle content, and spatial distribution.

[0040] Specifically, the steps for reconstructing an image based on capacitance values ​​are as follows: Select a suitable capacitance measurement system, such as using AC or pulse excitation signals. Place one or more sets of electrodes in the area to be imaged and connect them to the measurement system. For each location or time point, measure the capacitance value between the electrodes using sensors and record all data. Process the acquired data using a computer and apply an inverse problem-solving algorithm to deduce the internal structural information of the target object, ultimately generating an image result displayed to the user. Optimize and adjust the system parameters according to the required accuracy and resolution to improve the reconstruction effect and speed.

[0041] The specific steps of image reconstruction include: collecting image data and converting it into a digital signal; preprocessing the digital signal, including denoising and enhancement; dividing the digital signal into several small blocks and calculating the average capacitance value of each block; reconstructing the original image based on the average capacitance value of each block, i.e., filling the region with the corresponding color or grayscale value; and further optimizing and adjusting the reconstructed image to obtain better results. It is important to note that this process requires selecting appropriate capacitance models and parameters to accurately capture objects of different sizes and shapes. Furthermore, the impact of factors such as sampling rate and quantization error on the results must be considered and adjusted accordingly.

[0042] In the specific implementation scheme, the blockage detection subsystem includes a medium flow meter and a second data analysis device. The medium flow meter is used to collect the flow rate in the pipeline of the heavy medium shallow tank separator. The second data analysis device is communicatively connected to the medium flow meter and is used to determine whether the pipeline is blocked by the flow rate.

[0043] In this scheme, the flow rate in the pipeline can be collected by a medium flow meter, and the flow rate can be analyzed and processed by a second data analysis device to determine the flow rate changes. Then, the flow rate changes can be used to more accurately determine whether the pipeline is blocked.

[0044] In addition, the blockage detection subsystem may also include a pressure sensor and a third data analysis device. The pressure sensor detects the outlet pressure of the pipeline, and the third data analysis device is communicatively connected to the pressure sensor. The third data analysis device uses the outlet pressure to determine whether the pipeline is blocked.

[0045] In some embodiments, the aforementioned blockage-clearing subsystem includes multiple electromagnets, which are installed in pairs on both sides of the pipeline. All of the electromagnets are used to adjust the electromagnetic field according to the input current value, thereby loosening the blockage in the pipeline through the electromagnetic field.

[0046] In this scheme, pairs of electromagnets can be installed at a certain angle along the pipeline. The electromagnetic field can be adjusted at a certain frequency by a variable current, which will drive the magnetite powder in the blockage to move back and forth periodically. This will loosen the magnetite powder blockage, break up the agglomerates formed by sticky and wet particles, and disperse the agglomerates (the structure formed by multiple substances gathering together, the accumulated blockage clumps). This will remove the entrained coal slime and further eliminate the blockage in the pipeline.

[0047] Specifically, the electromagnetic unblocking device consists of a pair of electromagnets. The two electromagnets are installed at different heights on both sides of the medium pipe. The vertical angle between them can be adjusted from 0 to 75°. The magnetic field changes alternately. The frequency of the magnetic field change is adjusted according to the content of the magnetic material, so that the magnetic material moves back and forth alternately along the axial and radial directions of the pipe to remove the entrainment and deagglomerate.

[0048] Specifically, electromagnetic unblocking devices can also include: power supplies, sensors, motors, coils, filters, amplifiers, transmitting antennas, receiving antennas, and communication equipment. Power supplies provide current and voltage, such as generators, transformers, and inverters. Sensors detect and convert physical quantity signals into electrical signals, such as magnetometers and Hall effect sensors. Motors utilize magnetic field interactions to achieve energy conversion, such as DC motors, AC asynchronous motors, and stepper motors. Coils generate magnetic fields that influence the surrounding environment by changing the magnetic flux distribution through the insertion or cutting of wires in different directions, such as wound coils and helical coils. Filters utilize impedance characteristics to filter signals of different frequencies to reduce interference and ensure signal quality. Common devices include low-pass filters (LPF), high-pass filters (HPF), band-pass filters (BPF), and band-stop filters (BSF). Amplifiers amplify input signals and output them; common types include operational amplifiers, differential amplifiers, and digital amplifiers. Transmitting antennas radiate high-frequency oscillation signals generated internally by the wireless transmission system. Receiving antennas receive external wireless signals and convert them into electrical signals for transmission to the internal processing system. Communication devices such as mobile phones, televisions, and routers can alter the surrounding electromagnetic field to enable information transmission and reception.

[0049] In some embodiments, the aforementioned blockage clearing subsystem includes a vibration clearing device, which includes a housing, a striking ball, and a spring telescopic mechanism. The striking ball is located in the housing and is used to strike the pipeline, causing the blockage to fall off. The spring telescopic mechanism is located in the housing and is connected to the striking ball. The spring telescopic mechanism is used to extend and retract to drive the striking ball to move.

[0050] In this solution, a vibration unblocking device can be installed along the pipeline to knock off the blockage by striking the pipeline, thus further eliminating the blockage in the pipeline.

[0051] Of course, a vibration unblocking device can also be a vibrator. By controlling the vibration frequency of the vibrator, large pieces of blockage can be broken down, thereby eliminating the blockage.

[0052] Specifically, electromagnetic unblocking can be used for fine mud blockages, while resonant unblocking can be used for particulate blockages. After the first unblocking, a second blockage detection can be performed. If the blockage is still present, the blockage unblocking subsystem can be used again until the blockage is completely cleared.

[0053] In addition, the accumulation structure and particle size characteristics of large blockages can be determined using capacitance tomography, and the vibration frequency of the hitting ball can be adjusted to match the resonant frequency of the blockage, causing the blockage to resonate and break down until it is cleared.

[0054] Of course, a water pump can also be installed in the pipeline dredging system. The water output can be controlled by adjusting the opening of the valve in the water pump. The larger the water output, the greater the water pressure. In this way, the blockage can also be removed by flushing.

[0055] In addition, vibratory cleaning devices can also be one or more of the following: vibrating screens, oscillators, vibrating tables, vibrating motors, and magnetically driven agitators. Vibrating screens are used to separate particulate materials or solid particles from liquids. Oscillators generate periodic oscillating motion and are widely used in laboratories, medical fields, and other areas. Vibrating tables can simulate the structural response of buildings under natural disasters such as earthquakes and storms, and conduct seismic performance tests. Vibrating motors convert electrical energy into mechanical vibration energy and are used to manufacture various vibrating equipment and industrial machinery. Magnetically driven agitators use magnetic force as a transmission method to isolate rotating parts from the container and control their rotation speed and direction through frequency conversion speed regulation.

[0056] The blockage clearing subsystem may also include a filtration device. Installing a filter or other appropriate filtration device before the sorting machine can effectively reduce impurities and particulate matter entering the sorting machine and reduce the risk of pipe blockage.

[0057] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 2 This is a hardware structure block diagram of a mobile terminal for a control method of a pipeline unblocking system according to an embodiment of the present invention. Figure 2 As shown, a mobile terminal may include one or more ( Figure 2 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 2 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 2The more or fewer components shown, or having the same Figure 2 The different configurations shown.

[0058] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the device information display method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory and non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the aforementioned networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof. The transmission device 106 is used to receive or send data via a network. Specific examples of the aforementioned networks may include wireless networks provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0059] This embodiment provides a control method for a pipeline unblocking system that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0060] Figure 3 This is a schematic flowchart of a control method for a pipeline unblocking system according to an embodiment of this application. Figure 3 As shown, the method includes the following steps:

[0061] Step S201: Obtain the clogging parameters of the above-mentioned heavy medium shallow tank separator, wherein the clogging parameters include one or more of the capacitance parameters and the flow rate parameters;

[0062] Specifically, capacitance signals in the pipeline can be acquired using a capacitance tomography device, and flow rates in the pipeline can be acquired using a medium flow meter. Of course, the blockage parameters are not limited to the above-mentioned types; they can be any other feasible parameters, such as pressure data.

[0063] Step S202: Determine whether the pipeline of the heavy medium shallow tank separator is blocked based on the above-mentioned blockage parameters, and determine the cause of the blockage if the pipeline is blocked.

[0064] Specifically, the relationship between a single blockage parameter and a threshold can be used to determine whether a pipeline is blocked. Of course, when there are multiple blockage parameters, the weighted average of multiple blockage parameters can be calculated using the weighting coefficient method, and then the relationship between the final data and the threshold can be used to determine whether a pipeline is blocked.

[0065] In addition, the cause of the blockage can be determined when the pipeline is blocked, and different causes of blockages require different unblocking strategies.

[0066] Step S203: Control the operation of the blockage clearing subsystem according to the above-mentioned cause of blockage, so as to remove the blockage in the pipeline.

[0067] Specifically, once the blockage in the pipeline has been determined and the cause of the blockage has been identified, the operation of the blockage clearing subsystem can be controlled according to the cause of the blockage. For example, electromagnetic clearing can be used for blockages caused by fine mud, while resonant clearing can be used for blockages caused by particles.

[0068] In this embodiment, the capacitance and / or flow rate in the pipeline are obtained, and the presence of blockage is determined based on the blockage parameters. If a blockage occurs, the blockage clearing subsystem can be controlled to clear the blockage, thereby eliminating the blockage in the pipeline.

[0069] Determining whether a pipeline is blocked can be done by comparing it with a threshold. Specifically, the following steps can be taken to determine whether the pipeline of the heavy medium shallow trough separator is blocked based on the aforementioned blockage parameters: if the capacitance parameter is less than the capacitance threshold, the pipeline of the heavy medium shallow trough separator is blocked; if the flow rate parameter is less than the flow rate threshold, the pipeline of the heavy medium shallow trough separator is blocked.

[0070] In this scheme, by comparing the blockage parameter with the corresponding threshold, a simple and accurate method can be used to determine whether the pipeline is blocked without the need for complex calculations.

[0071] The capacitance threshold can be 1.01pF, 21.51pF, 82.22pF (picofarads), etc., and the flow threshold can be 1.5 m / s, 3 m / s, 4.5 m / s, 5 m / s, etc.

[0072] In order to determine the cause of the pipeline blockage, the present application can determine the cause of the blockage by means of the following steps: determining the cause of the blockage based on the blockage parameters, wherein the cause of the blockage includes fine sludge blockage and / or large particle blockage.

[0073] In this solution, the cause of the blockage can be determined based on the blockage parameters. Once the cause of the blockage is determined, the operation of the blockage clearing subsystem can be controlled more efficiently, thereby ensuring a better effect in the subsequent removal of the blockage.

[0074] Specifically, the blockage cross-sectional image can be reconstructed based on the blockage parameters, and the cause of the blockage can be determined based on the ratio of the area of ​​large particles to the area of ​​fine mud within the cross-sectional area.

[0075] Specifically, a reconstruction model can be constructed. The reconstruction is obtained by training multiple sets of training data. Each set of training data includes the following data acquired within a historical time period: historical capacitance parameters, historical congestion cross-sectional images corresponding to the historical capacitance parameters, historical flow parameters, and historical congestion cross-sectional images corresponding to the historical flow parameters. The currently acquired congestion parameters are input into the reconstruction model to obtain the reconstructed congestion cross-sectional image corresponding to the current congestion parameters.

[0076] In addition, image reconstruction can begin by preprocessing the collected capacitance and flow data to remove noise and outliers, ensuring data accuracy and reliability. Based on the characteristics and operating principles of the congested machine, features are extracted from the preprocessed data, such as trends and periodicity in capacitance and flow. A suitable image reconstruction algorithm is selected based on the feature extraction results; commonly used algorithms include interpolation, inversion, and model inference algorithms. Using the chosen algorithm, the feature data is mapped into the image space to generate a cross-sectional image of the congestion.

[0077] The following two examples illustrate this point:

[0078] 1. Assume the following data regarding the blockage machine's capacitor and flow rate:

[0079] Capacitors: [1.2, 1.3, 1.4, 1.5]

[0080] Flow rate: [10, 12, 15, 20]

[0081] Based on preprocessing and feature extraction, the feature data obtained is as follows:

[0082] The capacitance trend is increasing.

[0083] Traffic trend: increasing.

[0084] Based on the feature data, an interpolation algorithm is selected to reconstruct the image, resulting in a blockage cross-sectional image.

[0085] 2. Assume the following data regarding the blockage machine's capacitor and flow rate:

[0086] Capacitors: [2.1, 2.2, 2.3, 2.2]

[0087] Flow rate: [18, 20, 22, 20]

[0088] Based on preprocessing and feature extraction, the feature data obtained is as follows:

[0089] Capacitance change trend: fluctuating.

[0090] Traffic trend: stable.

[0091] Image reconstruction is performed by selecting a model inference algorithm based on feature data. The current blockage cross-section image is inferred using known blockage cross-section image samples and feature data.

[0092] Specifically, the ratio of the area of ​​large particles to the area of ​​fine mud within the cross-sectional area can determine whether the blockage is caused by fine mud or large particles. If the ratio is high, the blockage is caused by large particles; if the ratio is low, the blockage is caused by fine mud.

[0093] For example, large particles with an area of ​​100 mm 2 The fine clay has an area of ​​50mm. 2 The ratio of large particle area to fine mud area is 2, indicating that the blockage is caused by large particles. The large particle area is 30mm. 2 The fine clay has an area of ​​70mm. 2 The ratio of the area of ​​large particles to the area of ​​fine mud is 0.43, indicating that the clogging is caused by fine mud. Therefore, a ratio of 1 can be used as a threshold; clogging greater than or equal to the threshold is caused by large particles, while clogging less than the threshold is caused by fine mud.

[0094] Specifically, with a capacitance of 10uF (normal value is 20uF) and a flow rate of 5 liters / minute (normal value is 10 liters / minute), the low capacitance and low flow rate indicate that large particles are clogging the pipeline. Conversely, with a capacitance of 25uF (normal value is 20uF) and a flow rate of 15 liters / minute (normal value is 10 liters / minute), both the high capacitance and high flow rate indicate that fine sludge is clogging the pipeline.

[0095] The blockage clearing subsystem includes multiple devices. Different devices can be used to remove blockages caused by different reasons. In some embodiments, the blockage clearing subsystem includes multiple electromagnets and a vibratory clearing device. The vibratory clearing device includes a housing, a striking ball, and a spring telescopic mechanism. Multiple electromagnets are installed in pairs on both sides of the pipeline. All the electromagnets are used to adjust the electromagnetic field according to the input current value. The electromagnetic field loosens the blockage in the pipeline. The striking ball is located in the housing and is used to strike the pipeline, causing the blockage to fall off. The spring telescopic mechanism is located... In the aforementioned housing, the aforementioned spring telescopic mechanism is connected to the aforementioned striking ball. The aforementioned spring telescopic mechanism is used to extend and retract to drive the striking ball to move. The operation of the aforementioned blockage clearing subsystem is controlled according to the aforementioned cause of blockage. Specifically, this can be achieved through the following steps: when the aforementioned cause of blockage is fine sludge blockage, the power supply terminal outputs current to the aforementioned electromagnet; when the aforementioned cause of blockage is large particle blockage, the vibration clearing device is controlled to strike the aforementioned pipeline; when the aforementioned cause of blockage is both fine sludge blockage and large particle blockage, the power supply terminal outputs current to the aforementioned electromagnet, and the vibration clearing device is controlled to strike the aforementioned pipeline.

[0096] In this solution, when the blockage is characterized by fine sludge, a variable current is used to adjust the electromagnetic field at a certain frequency, causing the magnetite powder in the blockage to move back and forth periodically. This loosens the magnetite powder blockage, breaks the sticky and wet agglomerate force chains, and removes the entrained coal sludge, thereby further eliminating the blockage in the pipeline. When the blockage is characterized by large particles, the pipeline is struck to dislodge the blockage, which further eliminates the blockage. When the blockage is characterized by both fine sludge and large particles, both electromagnetic unblocking and resonant unblocking methods can be used to clear the blockage, thus further eliminating the blockage in the pipeline.

[0097] This solution proposes a pipeline unblocking system for a shallow trench separator for heavy media and a control method for the pipeline unblocking system. It can detect pipeline blockage and has the characteristics of high stability, strong operability, and wide application range.

[0098] This application achieves automatic blockage detection, electromagnetic unblocking of fine sludge blockages, and resonant unblocking of particulate blockages.

[0101] Example 1

[0102] (1) Equipment installation: Install a blockage detection subsystem and a blockage clearing subsystem on the outer wall of the rising medium flow pipeline of the heavy medium shallow trough separator and at the funnel;

[0103] (2) Blockage detection: The capacitance signal in the pipeline was collected by the capacitance tomography device and the blockage was detected. The capacitance signal was processed by the first data analysis device (data processing, image reconstruction). When the pipeline is blocked, the composition and distribution characteristics of the blockage are determined by data analysis, including the content of magnetic materials, coal slime content, coal particle content, etc.

[0104] (3) By automatically analyzing the blockage information, when the fine mud content is high, electromagnetic unblocking of fine mud blockage is carried out first. Pairs of electromagnets installed at a certain angle along the pipeline adjust the magnetic field at a certain frequency through variable current, which drives the magnetite powder in the blockage to move back and forth periodically, so that the magnetite powder blockage is loosened, the sticky and wet agglomeration force chain is destroyed, and the entrained coal mud is removed.

[0105] (4) When the fine mud blockage is loosened, the blockage still exists. The particle blockage resonance dredging is adopted: For blockages formed by large coal / debris particles, the blockage is removed by a vibration dredging device. The vibration dredging device consists of a spring telescopic mechanism, a striking ball and a shell. Based on the capacitance tomography imaging device, the accumulation structure characteristics and particle size characteristics of the large particle blockage are determined. The vibration frequency of the striking ball is adjusted to be the same as the resonance frequency of the blockage, so that the blockage is destroyed by resonance until the blockage is cleared.

[0106] A secondary blockage detection can also be performed. The blockage detection subsystem will detect the blockage again. If the blockage is still present, the blockage clearing subsystem will be used to clear it again until the blockage is completely cleared.

[0107] Example 2:

[0108] (1) Equipment installation: Install a blockage detection subsystem and a blockage clearing subsystem on the outer wall of the rising medium flow pipeline of the heavy medium shallow trough separator and at the funnel;

[0109] (2) Blockage detection: During the production process, the presence of blockage in the pipeline is determined by other links such as medium flow meter and motor. The capacitance signal in the pipeline is collected by capacitance tomography device, and the capacitance signal is processed by the first data analysis device to determine the composition and distribution characteristics of the blockage, including magnetic content, coal slime content, coal particle content, etc.

[0110] (3) By automatically analyzing the blockage information, when the fine mud content is high, electromagnetic unblocking of fine mud blockage is carried out first. Pairs of electromagnets installed at a certain angle along the pipeline adjust the magnetic field at a certain frequency through variable current, which drives the magnetite powder in the blockage to move back and forth periodically, so that the magnetite powder blockage is loosened, the sticky and wet agglomeration force chain is destroyed, and the entrained coal mud is removed.

[0111] (4) When the fine mud blockage is loosened, the blockage still exists. The particle blockage resonance dredging is adopted: For blockages formed by large coal / debris particles, the blockage is removed by a vibration dredging device. The vibration dredging device consists of a spring telescopic mechanism, a striking ball and a shell. Based on the capacitance tomography imaging device, the accumulation structure characteristics and particle size characteristics of the large particle blockage are determined. The vibration frequency of the striking ball is adjusted to be the same as the resonance frequency of the blockage, so that the blockage is destroyed by resonance until the blockage is cleared.

[0112] A secondary blockage detection can also be performed. The blockage detection subsystem will detect the blockage again. If the blockage is still present, the blockage clearing subsystem will be used to clear it again until the blockage is completely cleared.

[0113] Example 3

[0114] (1) Equipment installation: Install a blockage detection subsystem and a blockage clearing subsystem on the outer wall of the rising medium flow pipeline of the heavy medium shallow trough separator and at the funnel;

[0115] (2) Blockage detection: The capacitance signal in the pipeline was collected by the capacitance tomography device and the blockage was detected. The capacitance signal was processed by the first data analysis device. When the pipeline is blocked, the composition and distribution characteristics of the blockage are determined by data analysis, including the content of magnetic materials, coal slime content, coal particle content, etc.

[0116] (3) By automatically analyzing the blockage information, when only magnetic fine mud is blocked, only electromagnetic unblocking is required. Pairs of electromagnets installed at a certain angle along the pipeline adjust the magnetic field at a certain frequency through variable current, causing the magnetite powder in the blockage to move back and forth periodically, so that the magnetite powder blockage is loosened, the sticky wet agglomeration force chain is destroyed, the entrained coal sludge is removed, and the unblocking is completed.

[0117] A secondary blockage detection can also be performed. The blockage detection subsystem will detect the blockage again. If the blockage is still present, the blockage clearing subsystem will be used to clear it again until the blockage is completely cleared.

[0121] (3) By automatically analyzing the blockage information, when only large particles of impurities are blocked, only vibration is needed to clear the blockage. For blockages formed by large particles of coal / debris, the vibration clearing device is used to remove the blockage.

[0122] A secondary blockage detection can also be performed. The blockage detection subsystem will detect the blockage again. If the blockage is still present, the blockage clearing subsystem will be used to clear it again until the blockage is completely cleared.

[0123] This application also provides a control device for a pipeline dredging system. It should be noted that the control device for the pipeline dredging system in this application can be used to execute the control method for the pipeline dredging system provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0124] The control device of the pipeline dredging system provided in the embodiments of this application will be described below.

[0125] Figure 5 This is a structural block diagram of a control device for a pipeline unblocking system according to an embodiment of this application. Figure 5 As shown, the device includes:

[0126] The acquisition unit 100 is used to acquire the clogging parameters of the above-mentioned heavy medium shallow tank separator, wherein the clogging parameters include one or more of the capacitance parameters and the flow parameters.

[0127] Specifically, capacitance signals in the pipeline can be acquired using a capacitance tomography device, and flow rates in the pipeline can be acquired using a medium flow meter. Of course, the blockage parameters are not limited to the above-mentioned types; they can be any other feasible parameters, such as pressure data.

[0128] The determining unit 200 is used to determine whether the pipeline of the heavy medium shallow tank separator is blocked based on the above-mentioned blockage parameters, and to determine the cause of the blockage if the pipeline is blocked.

[0129] Specifically, the relationship between a single blockage parameter and a threshold can be used to determine whether a pipeline is blocked. Of course, when there are multiple blockage parameters, the weighted average of multiple blockage parameters can be calculated using the weighting coefficient method, and then the relationship between the final data and the threshold can be used to determine whether a pipeline is blocked.

[0130] In addition, the cause of the blockage can be determined when the pipeline is blocked, and different causes of blockages require different unblocking strategies.

[0131] The control unit 300 is used to control the operation of the blockage clearing subsystem according to the cause of the blockage, so as to remove the blockage in the pipeline.

[0132] Specifically, once the blockage in the pipeline has been determined and the cause of the blockage has been identified, the operation of the blockage clearing subsystem can be controlled according to the cause of the blockage. For example, electromagnetic clearing can be used for blockages caused by fine mud, while resonant clearing can be used for blockages caused by particles.

[0133] In this embodiment, the capacitance and / or flow rate in the pipeline are obtained, and the presence of blockage is determined based on the blockage parameters. If a blockage occurs, the blockage clearing subsystem can be controlled to clear the blockage, thereby eliminating the blockage in the pipeline.

[0134] Whether a pipeline is blocked can be determined by comparing it with a threshold. In specific implementation, the determining unit includes a first determining module and a second determining module. The first determining module is used to determine that the pipeline of the heavy medium shallow tank separator is blocked when the capacitance parameter is less than the capacitance threshold. The second determining module is used to determine that the pipeline of the heavy medium shallow tank separator is blocked when the flow parameter is less than the flow threshold.

[0135] In this scheme, by comparing the blockage parameter with the corresponding threshold, a simple and accurate method can be used to determine whether the pipeline is blocked without the need for complex calculations.

[0136] The capacitance threshold can be 1.01pF, 21.51pF, 82.22pF (picofarads), etc., and the flow threshold can be 1.5 m / s, 3 m / s, 4.5 m / s, 5 m / s, etc.

[0137] In order to determine the cause of pipeline blockage, the determining unit of this application includes a third determining module, which is used to determine the cause of the blockage based on the blockage parameters, wherein the cause of the blockage includes fine sludge blockage and / or large particle blockage.

[0138] In this solution, the cause of the blockage can be determined based on the blockage parameters. Once the cause of the blockage is determined, the operation of the blockage clearing subsystem can be controlled more efficiently, thereby ensuring a better effect in the subsequent removal of the blockage.

[0139] The blockage clearing subsystem includes multiple devices. Different devices can be used to remove blockages caused by different reasons. In some embodiments, the blockage clearing subsystem includes multiple electromagnets and a vibratory clearing device. The vibratory clearing device includes a housing, a striking ball, and a spring telescopic mechanism. Multiple electromagnets are installed in pairs on both sides of the pipe. All the electromagnets are used to adjust the electromagnetic field according to the input current value. The electromagnetic field loosens the blockage in the pipe. The striking ball is located in the housing and is used to strike the pipe, causing the blockage to fall off. The spring telescopic mechanism is located in the housing and works in conjunction with the striking ball... The ball is connected, and the aforementioned spring telescopic mechanism is used to reciprocate to drive the striking ball's movement. The blockage control subsystem is operated according to the cause of the blockage. The control unit includes a first control module, a second control module, and a third control module. The first control module controls the power supply to output current to the electromagnet when the blockage is characterized by fine sludge. The second control module controls the vibration unblocking device to strike the pipeline when the blockage is characterized by large particles. The third control module controls the power supply to output current to the electromagnet and controls the vibration unblocking device to strike the pipeline when the blockage is characterized by both fine sludge and large particles.

[0140] In this solution, when the blockage is characterized by fine sludge, a variable current is used to adjust the electromagnetic field at a certain frequency, causing the magnetite powder in the blockage to move back and forth periodically. This loosens the magnetite powder blockage, breaks the sticky and wet agglomerate force chains, and removes the entrained coal sludge, thereby further eliminating the blockage in the pipeline. When the blockage is characterized by large particles, the pipeline is struck to dislodge the blockage, which further eliminates the blockage. When the blockage is characterized by both fine sludge and large particles, both electromagnetic unblocking and resonant unblocking methods can be used to clear the blockage, thus further eliminating the blockage in the pipeline.

[0141] The control device of the aforementioned pipeline unblocking system includes a processor and a memory. The acquisition unit, determination unit, and control unit are all stored as program units in the memory, and the processor executes these program units to achieve the corresponding functions. All of the above modules reside in the same processor; alternatively, the modules may be located in different processors in any combination.

[0142] The processor contains a kernel, which retrieves the corresponding program unit from memory. One or more kernels can be configured, and adjusting kernel parameters can address the problem of blockages in the pipelines of existing heavy media shallow tank sorting machines.

[0143] The memory may include non-permanent memory in computer-readable media, such as random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0144] This invention provides a computer-readable storage medium that includes a stored program, wherein when the program is executed, it controls the device containing the computer-readable storage medium to perform the control method for the pipeline unblocking system.
