Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blanking pipe anti-blocking, more particularly to a coal yard blanking pipe intelligent anti-blocking and unblocking device. BACKGROUND

[0002] In the process of coal transportation in thermal power plants, belt conveyors are widely used to build efficient and continuous conveying systems. The seamless connection of multiple or multi-stage conveyors is crucial in this system. The transfer device, as a key component connecting each conveying section, directly affects the smoothness and stability of the entire conveying system. The blanking pipe, also known as the coal dropping pipe, is the core component of the transfer device, responsible for smoothly guiding coal from one conveyor to another.

[0003] However, in actual operation, the moisture in the coal often causes dust coal to adhere to the inner wall of the blanking pipe. Over time, these coal dust gradually dries and accumulates, forming thick coal scale, which not only narrows the effective passage of the blanking pipe but also greatly increases the risk of blockage, severely affecting the normal transportation of coal.

[0004] To solve this problem, existing technologies have proposed various solutions. For example, an intelligent anti-blocking blanking pipe (authorized publication number CN221638987U) and an automatic anti-blocking device for a blanking pipe and its control method (application publication number CN117566315A) both use detection units (such as camera detection and ultrasonic detection) to monitor the blockage inside the blanking pipe in real time. Once blockage is detected, an external vibration unit is activated to shake the blanking pipe, causing the adhering coal to fall off, thereby achieving the purpose of unblocking. However, this method has limited effectiveness in dealing with small pieces of sticky coal, as small pieces of coal are difficult to fall off the inner wall during the shaking process due to their light weight and small inertia.

[0005] To overcome this limitation, existing technologies have explored other cleaning methods. For example, a new coal dropping pipe self-cleaning device (authorized publication number CN212901485U) is disclosed in a Chinese patent. In the disclosure, a coal scraping plate is rotated inside the blanking pipe, and a hydraulic push rod is used to drive the coal scraping plate to move in and out of the coal dropping pipe, effectively cleaning the inner wall of the blanking pipe. However, this cleaning method is mainly suitable for circular tubular blanking pipes and is not suitable for rectangular blanking pipes commonly used in actual work, thereby limiting its application range.

[0006] In view of this, the present application has comprehensively improved and optimized the blanking pipe based on the analysis of the shortcomings of existing technologies, aiming to develop a coal yard blanking pipe intelligent anti-blocking and unblocking device. SUMMARY

[0007] In view of the problems in the prior art, the present application aims to provide a coal yard material falling pipe intelligent anti-blocking and unblocking device, which can open the unblocking assembly when blocking occurs in the segmented pipe, so that the rubber layer expands and contracts, the surface of the rubber layer deforms, the contact area and state between the coal and the rubber layer change, and the adhesion between the coal and the rubber layer is destroyed, so that the coal is easily removed.

[0008] To solve the above problems, the application adopts the following technical scheme.

[0009] A coal yard material falling pipe intelligent anti-blocking and unblocking device comprises:

[0019] The exhaust valve is installed outside the segmented pipe, and the number of the exhaust valves corresponds to the number of the segmented pipes, and the exhaust valve and the gas delivery valve are both electrically controlled.

[0020] The suction pipe is used to connect multiple sets of exhaust valves in series, and the inside of the suction pipe is connected to the inside of the cavity through the exhaust valves. One end of the suction pipe is connected to the suction port of the suction pump.

[0021] A controller is installed on the outside of one of the segmented pipes and is electrically connected to the exhaust valve and the supply valve, respectively.

[0022] Furthermore, the unblocking component also includes:

[0023] Inner sleeve, wherein the inner sleeve is disposed within a cavity on the segmented pipe;

[0024] The air vents are arranged in multiple sets and are formed through the inner sleeve.

[0025] The protrusion is installed at both the upper and lower ends of the inner sleeve, and is installed on the side of the inner sleeve near the inner wall of the segmented tube.

[0026] Furthermore, the unblocking component also includes:

[0027] A sleeve is installed on the outside of the segmented pipe, and the inside of the sleeve is in communication with the inside of the cavity.

[0028] An impact hole is provided on the inner sleeve, and the position of the impact hole corresponds to the position of the sleeve.

[0029] A permanent magnet block is movably disposed inside the sleeve, and the permanent magnet block can pass through the impact hole and impact the rubber layer when the sleeve moves;

[0030] An electromagnet is installed at the end of the sleeve away from the cavity, and the electromagnet is electrically connected to the controller;

[0031] A first spring is disposed between the electromagnet and the permanent magnet, with its left and right ends fixedly connected to the electromagnet and the permanent magnet, respectively.

[0032] Furthermore, the unblocking component also includes:

[0033] The second spring is installed between the support plate and the protrusion, and its upper and lower ends are fixedly connected to the support plate and the protrusion, respectively.

[0034] Furthermore, the unblocking component also includes:

[0035] A magnetic guide block is disposed at both the upper and lower ends of the sleeve and is located inside the cavity.

[0036] A spring is disposed between the magnetic block and the inner sleeve, and both ends of the spring are fixedly connected to the magnetic block and the inner sleeve, respectively.

[0037] Furthermore, the unblocking component also includes:

[0038] A heating box is installed between the gas supply pipe and the gas pump.

[0039] A heating wire is installed inside the heating box and is electrically connected to the controller.

[0040] Furthermore, the unblocking component also includes:

[0041] A pressure sensor is installed on the inner wall of the segmented pipe. The pressure sensor is used to detect the air pressure in the cavity chamber of the segmented pipe. The pressure sensor is electrically connected to the controller.

[0047] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0048] (1) When blockage occurs inside the segmented pipe, the unblocking component is activated to cause the rubber layer to expand and contract. The surface of the rubber layer will deform, which will cause changes in the contact area and contact state between the coal and the rubber layer. This change will destroy the adhesion between the coal and the rubber layer, making the coal easy to fall off. In addition, the rubber layer will drive the rubber layer to vibrate at a high frequency when it expands and contracts, which will facilitate the rapid fall off of the loosely adhered coal and ensure the smooth flow inside the segmented pipe.

[0049] (2) This scheme can effectively reduce blockage events in the segmented pipes through real-time prediction and early intervention, ensuring the continuity and stability of coal transportation, thereby improving the overall transportation efficiency.

[0050] (3) This solution compares the monitoring results with the prediction results in real time and adjusts the learning model accordingly. It can continuously approach the actual blockage situation and significantly improve the accuracy of predicting blockages inside the segmented pipe in the future. The accurate prediction results provide strong support for decision-making such as production scheduling, equipment maintenance, and blockage prevention. Staff can formulate more scientific and reasonable plans based on these prediction results to reduce production interruptions and equipment damage caused by blockages. Attached Figure Description

[0061] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0062] Please see Figures 1 to 7 A smart anti-clogging and unblocking device for coal yard feed pipes includes segmented pipes 1 and receiving hoppers 2. Multiple sets of segmented pipes 1 are connected end-to-end. The receiving hopper 2 is fixedly installed at the upper end of the uppermost set of segmented pipes 1. Support plates 12 are fixedly installed on the inner walls of the upper and lower ends of the segmented pipes 1. An unblocking assembly is installed on the segmented pipes 1 and is used to remove coal blockages within the segmented pipes 1. The unblocking assembly includes: a rubber layer 13 located inside the segmented pipes 1, with its upper and lower ends fixedly connected to the corresponding support plates 12; the rubber layer 13, support plates 12, and segmented pipes 1 together forming a cavity; an air pump 5 installed outside one set of segmented pipes 1 and used to fill the cavity with air; and a suction pump 7 installed outside one set of segmented pipes 1 and used to suction air into the cavity.

[0063] The unblocking assembly also includes an air supply valve 10, which is installed outside the segmented pipe 1, and the number of air supply valves 10 corresponds to the number of segmented pipes 1; an air supply pipe 6, which connects multiple sets of air supply valves 10 in series, and the interior of the air supply pipe 6 is interconnected with the interior of the cavity through the air supply valves 10, with one end of the air supply pipe 6 connected to the exhaust port of the air supply pump 5; and an exhaust valve 11, which is installed outside the segmented pipe 1. The number of valves corresponds to the number of segmented pipes 1. Both the exhaust valve 11 and the supply valve 10 are electrically controlled. The intake pipe 8 is used to connect multiple sets of exhaust valves 11 in series. The interior of the intake pipe 8 is connected to the interior of the cavity through the exhaust valves 11. One end of the intake pipe 8 is connected to the intake port of the intake pump 7. The controller 9 is installed on the outside of one of the segmented pipes 1. The controller 9 is electrically connected to the exhaust valve 11 and the supply valve 10 respectively.

[0064] An ultrasonic transmitter 3 is installed on the outer surface of the segmented pipe 1; an ultrasonic receiver 4 is installed on the side of the segmented pipe 1 away from the ultrasonic transmitter 3; and a processing unit is installed inside the controller 9, which determines whether there is a blockage in the segmented pipe 1 based on the monitoring results of the ultrasonic transmitter 3 and the ultrasonic receiver 4.

[0065] The air pressure sensor 27 is installed on the inner wall of the segmented pipe 1. The air pressure sensor 27 is used to detect the air pressure in the cavity of the segmented pipe 1. The air pressure sensor 27 is electrically connected to the controller 9.

[0066] By adopting the above technical solution, the ultrasonic transmitter 3 emits sound waves into the corresponding segmented pipe 1. After passing through the segmented pipe 1, the sound waves reach the ultrasonic receiver 4 and are received by the ultrasonic receiver 4. The processing unit determines whether there is a blockage in the segmented pipe 1 based on the signal changes received by the ultrasonic receiver 4. If there is a blockage in the segmented pipe 1 and the blockage reaches a preset threshold, the controller 9 will start the air pump 5, which will input air into the air supply pipe 6. At this time, the controller 9 controls the corresponding air supply valve 10 on the blocked segmented pipe 1 to open, and air will enter the cavity inside the segmented pipe 1. As air continuously enters, the rubber layer 13 will continuously stretch and expand, and its surface will deform, causing changes in the contact area and contact state between the coal and the rubber layer 13. This change will damage the contact between the coal and the rubber layer 13. The adhesive force between the rubber layers 13 makes it easy for the coal to fall off. After the rubber layer 13 expands, the controller 9 controls the corresponding gas supply valve 10 to close and the corresponding exhaust valve 11 to open. The suction pump 7 draws air from the cavity through the suction pipe 8 and causes the rubber layer 13 to contract rapidly. By repeatedly controlling the expansion and contraction of the rubber layer 13, the coal can be easily detached from the rubber layer 13, thus completing the unblocking work inside the segmented pipe 1. The structure is simple and the operation is convenient. The air pressure sensor 27 is used to detect the air pressure in the cavity of the segmented pipe 1. When filling the cavity with air, if the high pressure in the cavity reaches the preset threshold, the filling stops and the gas supply to the outside is switched to the inside. When the negative pressure in the cavity reaches the preset threshold, the filling is switched to the inside. This avoids the problem of the rubber layer 13 expanding too much and cracking.

[0067] In some embodiments of the present invention, the unblocking component further includes an inner sleeve 15, which is disposed in a cavity on the segmented pipe 1; vents 16, which are arranged in multiple sets and are opened through the inner sleeve 15; and protrusions 26, which are installed at the upper and lower ends of the inner sleeve 15 and are installed on the side of the inner sleeve 15 near the inner wall of the segmented pipe 1.

[0068] Heating box 24 is installed between gas supply pipe 6 and gas pump 5; heating wire 25 is installed inside heating box 24 and is electrically connected to controller 9.

[0069] By adopting the above technical solution, when air is injected into the cavity of the segmented pipe 1, the controller 9 controls the heating wire 25 to heat it. In this way, the airflow is heated before passing through the air supply pipe 6. After the hot air enters the cavity, it heats the rubber layer 13. Heating the rubber layer 13 can improve the stretching and contraction capacity of the rubber layer 13. When the cavity is under negative pressure, the rubber layer 13 will stick tightly to the inner sleeve 15. At the same time, the rubber layer 13 located at the air hole 16 will move into the air hole 16. Finally, the rubber layer 13 at this location will separate from the sticky coal and enter the air hole 16, thereby reducing the contact area between the sticky coal and the rubber layer 13. This makes it easier for the coal to detach from the rubber layer 13. With the subsequent expansion of the rubber layer 13, the coal can be further removed from the rubber layer 13.

[0070] In some embodiments of the present invention, the unblocking assembly further includes a sleeve 17, which is installed outside the segmented pipe 1 and is in communication with the interior of the cavity; an impact hole 21, which is opened on the inner sleeve 15 and is positioned corresponding to the position of the sleeve 17; a permanent magnet 18, which is movably disposed inside the sleeve 17 and can pass through the impact hole 21 to impact the rubber layer 13 when the sleeve 17 moves; an electromagnet 20, which is installed at the end of the sleeve 17 away from the cavity and is electrically connected to the controller 9; and a first spring 19, which is disposed between the electromagnet 20 and the permanent magnet 18 and is fixedly connected to the electromagnet 20 and the permanent magnet 18 at its left and right ends, respectively.

[0071] By adopting the above technical solution, when the cavity is under negative pressure, the rubber layer 13 is tightly attached to the inner sleeve 15. At this time, the controller 9 will control the electromagnet 20 to be energized instantaneously, generating a strong magnetic force. The magnetic force pushes the permanent magnet block 18 to move into the impact hole 21 and impact the rubber layer 13 at the corresponding impact hole 21. The rubber layer 13 will vibrate after being impacted. The vibration causes the loosely adhered coal material on the rubber layer 13 to fall off. Because the rubber layer 13 is tightly attached to the inner sleeve 15, when the permanent magnet block 18 impacts the local part of the rubber layer 13, it will drive the inner sleeve 15 to vibrate. The inner sleeve 15 drives the entire rubber layer 13 to vibrate, thereby improving the vibration effect of the rubber layer 13 and improving the coal detachment effect. When the permanent magnet block 18 moves away from the electromagnet 20, it will stretch the first spring 19. After the electromagnet 20 is de-energized, it will no longer generate magnetic repulsion force on the permanent magnet block 18. The first spring 19 will contract and pull the permanent magnet block 18 back to the initial position.

[0072] In some embodiments of the present invention, the unblocking assembly further includes a second spring 14, which is installed between the support plate 12 and the protrusion 26, and the upper and lower ends of the second spring 14 are fixedly connected to the support plate 12 and the protrusion 26 respectively.

[0073] Magnetic guide block 23 is disposed at the upper and lower ends of sleeve 17 and is located in the cavity; spring piece 22 is disposed between magnetic guide block 23 and inner sleeve 15, and the two ends of spring piece 22 are fixedly connected to magnetic guide block 23 and inner sleeve 15 respectively.

[0074] By adopting the above technical solution, when the permanent magnet 18 moves inside the sleeve 17, it will act on the magnetic guide block 23 through magnetic force. The magnetic guide block 23 can be made of iron, cobalt, nickel, or iron-cobalt-nickel alloy materials. When the permanent magnet 18 approaches the magnetic guide block 23, it will attract the magnetic guide block 23 and make the magnetic guide block 23 move closer to the permanent magnet 18 and bend the spring piece 22. When the permanent magnet 18 moves away from the magnetic guide block 23, the attraction force on the magnetic guide block 23 weakens. At this time, the elastic force of the spring piece 22 on the magnetic guide block 23 is greater than the attraction force of the permanent magnet 18 on the magnetic guide block 23. The spring piece 22 resets and shakes, and it shakes up and down. The shaking of the magnetic guide block 23 and the spring piece 22 increases the vibration amplitude and vibration frequency of the inner sleeve 15, thereby increasing the vibration amplitude and vibration frequency of the rubber layer 13, which facilitates the coal material on the rubber layer 13 to fall off.

[0075] In some embodiments of the present invention, the processing unit records the blockage time nodes in the segmented pipe 1 each time, and records the duration of coal flow in the segmented pipe 1 between two sets of time nodes. The time nodes and the duration of coal flow are used as historical data. The processing unit uses a learning model to analyze the historical data, predicts the blockage node and blockage result of the segmented pipe 1 at the next moment through the historical data, and activates the unblocking component at the moment before the blockage in the segmented pipe 1.

[0076] By adopting the above technical solution, the processing unit first uses the ultrasonic transmitter 3 and ultrasonic receiver 4 to monitor and record in real time the specific time points of each blockage in the segmented pipe 1. These time points include, but are not limited to, the start and end times of the blockage, as well as the interval time between each blockage. The processing unit also records the duration of normal coal flow within the segmented pipe 1 between two sets of blockage time points. This data reflects the flow efficiency of the coal in the pipeline and its transportation status under non-blockage conditions. The processing unit saves the collected time point and coal flow duration data as historical data, forming a database containing multiple blockage events and their related information. Using learning models (such as time series analysis, neural networks, etc.), the processing unit analyzes this historical data to identify the occurrence of blockages. Based on the analysis results of historical data, the processing unit constructs a predictive model to predict the blockage node (i.e., when and where blockage may occur) and blockage results (such as the severity of blockage and the possible duration of blockage) of segment pipe 1 at the next moment. The processing unit continuously runs the predictive model and predicts the blockage situation that will occur in segment pipe 1 in real time based on the current and recent coal flow data. The processing unit automatically triggers the start command of the blockage clearing component a moment before the predicted blockage occurs. After the blockage clearing operation, the status of segment pipe 1 continues to be monitored. Through real-time prediction and early intervention, the blockage events in segment pipe 1 can be effectively reduced, ensuring the continuity and stability of coal transportation, thereby improving the overall transportation efficiency.

[0077] In some embodiments of the present invention, the processing unit compares the monitoring results of the ultrasonic transmitter 3 and the ultrasonic receiver 4 with the prediction results, performs numerical processing on the monitoring results and the prediction results, calculates the difference between the monitoring results and the prediction results, uses the difference as a feedback signal to adjust the learning model to obtain a new learning model, uses the new learning model to predict the blockage inside the segmented pipe 1 in the future, automatically adjusts the prediction model according to the difference, so that the subsequent prediction results are similar to the monitoring results at the current moment, and uses the new learning model to predict the interior of the segmented pipe 1 in the future to obtain a new prediction result.

[0078] By adopting the above technical solution, the signals monitored by the ultrasonic transmitter 3 and ultrasonic receiver 4 are converted into electrical signals and further processed into digital data that can be used for analysis. The processing unit uses an existing learning model to predict the future blockage situation inside the segmented pipe 1 based on historical data and currently available information, generating prediction results. The processing unit quantifies the actual blockage situation (such as blockage location and degree) obtained by ultrasonic monitoring and the prediction results for quantitative comparison, calculating the difference between the monitoring results and the prediction results. This includes location difference, time difference, and degree of blockage difference, to evaluate the accuracy of the prediction. The calculated difference is used as a feedback signal and input into the learning model. This feedback signal reflects the current model's predictive ability deficiencies and areas for improvement. Based on the feedback signal, the processing unit... The learning model is adjusted, including adjusting model parameters, optimizing algorithms, and adding or deleting feature variables, to better adapt the model to actual congestion conditions. Using the adjusted new learning model, a new prediction of the future congestion situation inside segment 1 is made. The internal situation of segment 1 is continuously monitored by ultrasonic transmitter 3 and ultrasonic receiver 4. The new prediction results are compared with the real-time monitoring results to verify the prediction accuracy of the new model. Based on the difference between the new prediction results and the monitoring results, the processing unit automatically adjusts the prediction model, forming a continuous optimization loop. Through continuous feedback and adjustment, the subsequent prediction results tend to be the same as the current monitoring results, improving the accuracy and reliability of the prediction. Using the new learning model that has been optimized multiple times, the future internal situation of segment 1 is predicted to obtain new prediction results. This invention compares monitoring results with prediction results in real time and adjusts the learning model accordingly, which can continuously approach the actual blockage situation and significantly improve the accuracy of predicting future blockages inside segmented pipe 1. The accurate prediction results provide strong support for decisions such as production scheduling, equipment maintenance, and blockage prevention. Staff can formulate more scientific and reasonable plans based on these prediction results to reduce production interruptions and equipment damage caused by blockages.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
