Description

Technical Field

[0001] This application relates to the field of coking equipment technology, and in particular to a shaking feeder in a coking process tamping station, specifically a detection device and method for detecting the material flow of the shaking feeder in a coking process tamping station. Background Technology

[0002] In the process of tamping and side-loading coal cakes in coking enterprises, the tamping and forming of coal cakes is one of the key factors in the quality of coke forming. The composition of coal powder, dryness and wetness, effective tamping frequency of tamping hammer, effective tamping work, and uniformity of feeding by shaking feeder are all key factors affecting coal cake forming. Therefore, effective monitoring and control of the tamping and forming process is an important means of controlling the coal cake forming process.

[0003] Currently, in the coking plant production process, the material flow of the feeder is judged manually by on-site workers. Due to the long and narrow working area of ​​the tamping station, one worker is usually needed to assist in the judgment, while another worker operates the control box, manually starting and stopping the feeder and handling abnormal problems, such as activating the air cannon to clear blockages when the coal tower feed is stuck. Because the tamping station is noisy, and communication between the two workers is done through hand gestures, the reliability and timeliness of message transmission are low.

[0004] Therefore, although current manual judgment can maintain production, it cannot achieve more refined control, making it difficult to improve production quality. Furthermore, from a scientific control perspective, the feeding frequency of the vibrating feeder cannot be accurately observed by the human eye, and the judgment of on-site personnel relies on long-term experience. That is, the existing material flow detection method relies on personnel experience, resulting in low reliability and accuracy of judgment results, large judgment errors, and low timeliness of information. This leads to large differences in the feeding of the vibrating feeder, poor uniformity of material drop, and large differences in the height of coal cake formation, and the quality of coal cake production still needs to be improved.

[0005] Therefore, it is urgent to propose a new technical solution to address the problems existing in the current technology. Summary of the Invention

[0006] This application provides a material flow detection device and method for a shaking feeder in a coking process tamping station, in order to solve the problems of large feeding differences in the current shaking feeder and the need to further improve the quality of coal cake production.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] On one hand, this application provides a material flow detection device for a shaking feeder in a coking process tamping station, including a shaking feeder hopper and a drive assembly for driving the shaking feeder hopper to reciprocate in the horizontal direction; the drive assembly includes a motor, a sprocket connected to the power output end of the motor, a crank connected to the sprocket via chain transmission, and a connecting rod connected to the crank, the connecting rod being connected to the shaking feeder hopper; a proximity sensor detection assembly is provided on one or both sides of the shaking feeder hopper along the direction of movement, and several multi-point detection sensors are provided at the discharge end of the shaking feeder hopper; the shaking feeder hopper is located below the coal powder discharge outlet on the coal tower; when the shaking feeder hopper is driven to reciprocate, coal powder falls from the shaking feeder hopper into the coal trough of the coal loading car; the proximity sensor detection assembly monitors the feeding cycle of the shaking feeder hopper in real time, and the multi-point detection sensors monitor the falling surface and falling time in real time; both the proximity sensor detection assembly and the multi-point detection sensors are connected to a controller, and the controller receives the sensor signals in real time and outputs material flow numerical signals.

[0009] In the above technical solution, the shaking feeding hopper includes a horizontally arranged hopper bottom surface, which is rectangular in shape. Three sides of the hopper bottom surface are surrounded by hopper baffles. A material drop plate is provided on the open side of the hopper bottom surface. The material drop plate forms an angle with the hopper bottom surface. The surface of the material drop plate is lower than the hopper bottom surface. Several multi-point detection sensors are arranged at intervals on the outer edge of the material drop plate away from the hopper bottom surface. The several multi-point detection sensors are evenly distributed.

[0010] Optionally, a fixed support is provided at the bottom of the shaking feed hopper, and the shaking feed hopper moves back and forth relative to the fixed support. A proximity sensor detection component is fixed on one or both sides of the fixed support.

[0011] Optionally, the pulverized coal in the coal tower falls from the pulverized coal discharge port into the shaking feed hopper to achieve feeding of the shaking feed hopper.

[0012] Optionally, the shaking feed hopper is set above the coal trough of the coal loading car. When the shaking feed hopper is driven to move back and forth, the coal powder in the shaking feed hopper falls into the coal trough of the coal loading car, thus realizing the feeding of the shaking feed hopper.

[0013] Optionally, the proximity sensor detection component includes a proximity sensor, and both the proximity sensor and the multi-point detection sensor are connected to the controller signal. The controller outputs an action control signal to the motor of the drive component based on the output material flow value signal.

[0014] Optionally, laser radar sensors are installed on both sides of the discharge end of the shaking feed hopper. The laser radar sensors are connected to the controller signal. The controller receives the sensing signal from the laser radar sensors and outputs the discharge volume value signal.

[0015] On the other hand, this application also provides a method for detecting the material flow of a vibrating feeder in a coking process tamping station. This method uses the aforementioned material flow detection device for a vibrating feeder in a coking process tamping station, and includes the following steps:

[0016] S1: The motor of the drive component starts, and the crank drives the connecting rod, which in turn drives the rocking feed hopper to move back and forth. During this time, the coal powder in the coal tower falls into the rocking feed hopper, and the rocking feed hopper feeds material into the coal trough of the coal loading car during the movement.

[0017] S2: During the reciprocating movement of the shaking feed hopper, the feeding cycle of the shaking feed hopper is monitored in real time by the proximity sensor detection component. During the falling process of the coal powder in the shaking feed hopper, the falling surface and falling time are monitored in real time by the multi-point detection sensor.

[0018] S3: The proximity sensor detection component and the multi-point detection sensor send the detected signals to the controller. The controller calculates the single-sided area of ​​the material and the material flow rate of a single drop based on the received signals.

[0019] In the above technical solution, the proximity sensor detection component detects the reciprocating movement of the shaking feed hopper, records the feeding cycle based on the change of the switch signal of the proximity sensor, and the controller determines the feeding frequency and feeding time based on the feeding cycle, and stores the feeding frequency and feeding time.

[0020] Optionally, a multi-point detection sensor is used to monitor the material dropping surface and dropping time in real time. The controller calculates the single-sided area of ​​the material dropping based on the sensing signals received from the multi-point detection sensor, and then determines the size of the material flow in a single dropping operation.

[0021] Optionally, the controller calculates the amount of coal powder during the tamping process based on the sensing signals obtained from the proximity sensor detection component and the multi-point detection sensor.

[0022] Optionally, the controller calculates the feeding frequency of the shaking feed hopper based on the sensing signal obtained from the proximity sensor detection component, and determines whether the motor's working status is normal based on the feeding frequency. If the motor's working status is determined to be abnormal, a motor maintenance prompt signal is issued.

[0023] Optionally, the controller calculates the single-sided area of ​​the material falling based on the sensing signals obtained from the multi-point detection sensors, and determines whether the coal tower feeding is normal based on the single-sided area of ​​the material falling. If it is determined that the coal tower feeding is abnormal, the controller starts the abnormal handling program of the coal tower.

[0024] Compared with the prior art, this application has the following advantages:

[0025] 1. This application provides a material flow detection device for a shaking feeder in a coking process tamping station. It is applied to the process monitoring of the tamping station during coal cake formation. This device allows for low-cost structural modification of the existing shaking feeder structure, achieving non-contact detection. Specifically, proximity sensor detection components are installed on one or both sides of the shaking feeder hopper along the direction of movement. Several multi-point detection sensors are installed at the discharge end of the shaking feeder hopper. Both the proximity sensor detection components and the multi-point detection sensors are connected to a controller. The proximity sensor detection components monitor the feeding cycle of the shaking feeder hopper in real time, while the multi-point detection sensors monitor the material drop surface and drop time in real time. The controller outputs a material flow numerical signal based on the received sensor signals. Therefore, the material flow detection device provided by this application can reduce manual intervention and labor costs, scientifically monitor the material flow, and achieve statistical analysis of the feeding frequency of the shaking feeder through proximity sensor detection. This ensures uniform feeding, guarantees uniform material drop at each frequency, ensures uniform coal cake growth, and improves coal cake quality.

[0026] 2.

[0027] 3. This application uses a multi-point detection sensor to detect the feeding and dropping surface. The controller (PLC) divides the multiple points and calculates the material flow value and the percentage of the material flow detection result. It also provides feedback on the percentage data of the single dropping volume, thereby ensuring uniform feeding at each frequency, ensuring the uniformity of coal cake growth, and assisting in the judgment of coal cake growth height.

[0028] 4. This application uses proximity sensors to detect the feeding frequency of the feeder and multi-point detection sensors to detect the percentage of material flow results, thereby determining and recording the cumulative volume of material flow throughout the tamping process.

[0037] Example 1

[0038] In current coking plant production, there is no electromechanical detection method for the material flow of the shaking feeder. It is all judged manually by on-site workers, which leads to large judgment errors. In addition, it is impossible for humans to judge the feeding frequency of the shaking feeder, resulting in poor uniformity of material drop due to differences in feeding frequency. Furthermore, manual judgment requires two workers, and the reliability and timeliness of the judgment results are poor. The feeding of the shaking feeder is very different, resulting in large differences in the coal cake forming height.

[0039] To address the problems existing in the prior art, this embodiment provides a material flow detection device for a shaking feeder in a coking process tamping station. This device is applied to the process monitoring of the tamping station in coal cake forming. It can monitor the falling material flow, and the controller can control and adjust the relevant falling mechanism by analyzing the monitoring data to ensure uniform falling at each frequency. This effectively solves the problems in the prior art, such as the inability to accurately define the boundary of manual judgment, the easy occurrence of errors in judgment, and the easy negligence in manual judgment. It also solves the influence of human factors on the determination of the material flow size.

[0040] This application provides a material flow detection device for a shaking feeder in a coking process tamping station. The device includes a shaking feeder, a shaking feed hopper, and a drive assembly that drives the shaking feed hopper to reciprocate horizontally. In specific application scenarios, the shaking feeder in this application is the shaking feeder used in existing enterprise production practices. By making simple structural modifications to the existing shaking feeder, the material flow detection device for a coking process tamping station provided in this application can be obtained; specifically, relevant structural additions are made to the shaking feed hopper.

[0041] In this embodiment, see Figure 2 The shaking feed hopper 4 includes a horizontally positioned hopper bottom surface, which is rectangular in shape. Three sides of the hopper bottom surface are surrounded by hopper guards. The fourth side of the hopper bottom surface, which is the opening side of the hopper, is equipped with a discharge plate. To facilitate material discharge, the discharge plate forms an angle with the hopper bottom surface, and the surface of the discharge plate is lower than the hopper bottom surface.

[0042] In a specific modification and installation example, several multi-point detection sensors are spaced apart on the outer edge of the material discharge plate away from the bottom of the hopper, with these sensors evenly distributed. This embodiment uses the example of three multi-point detection sensors spaced apart on the outer edge of the material discharge plate away from the bottom of the hopper for illustration. Figure 2 The first multi-point detection sensor 7, the second multi-point detection sensor 8, and the third multi-point detection sensor 9 are provided in the embodiment. In other embodiments, any number of multi-point detection sensors can also be provided.

[0043] In addition to installing multi-point detection sensors on the edge of the material drop plate, proximity sensor detection components 6 are also installed on one or both sides of the shaking feed hopper. (See [link]) Figure 2The proximity sensor detection component 6 is not connected to the rocking feed hopper 1, meaning that the proximity sensor detection component 6 remains stationary when the rocking feed hopper 1 moves. If the rocking feed hopper moves back and forth in the front-to-back direction, the proximity sensor detection component is located on the left and right sides of the rocking feed hopper, close to the discharge plate.

[0044] In this embodiment, a fixed support is provided below the rocking feed hopper 4. The rocking feed hopper 4 reciprocates relative to the fixed support. The fixed support can be a gantry-like support installed below the rocking feed hopper 4, which not only supports the rocking feed hopper 4 but can also be surface-treated to reduce friction and provide a guiding function. A proximity sensor detection component 6 is fixed to one or both sides of the fixed support. When the rocking feed hopper 4 reciprocates, the proximity sensor detection component 6 detects the feeding cycle of the rocking feed hopper 4.

[0045] In this embodiment, a proximity sensor detection component 6 is provided on one or both sides of the shaking feeder hopper 4 of the coking process tamping station along its moving direction. Several multi-point detection sensors are provided at the discharge end of the shaking feeder hopper 4. The shaking feeder hopper 4 is located below the coal powder discharge port on the coal tower. The coal powder in the coal tower falls from the coal powder discharge port into the shaking feeder hopper 4, realizing the feeding of the shaking feeder hopper 4. The shaking feeder hopper 4 is located above the coal trough of the coal charging car. When the shaking feeder hopper 4 is driven to move back and forth, the coal powder in the shaking feeder hopper 4 falls into the coal trough of the coal charging car, realizing the feeding of the shaking feeder hopper 4.

[0046] When the shaking feed hopper 4 is driven to reciprocate, the pulverized coal falls from the shaking feed hopper 4 into the coal trough of the coal loading car. The proximity sensor detection component 6 monitors the feeding cycle of the shaking feed hopper 4 in real time, and the multi-point detection sensor monitors the falling surface and falling time in real time. Both the proximity sensor detection component 6 and the multi-point detection sensor are connected to the controller. The controller receives the sensor signals in real time and outputs the material flow value signal. The controller outputs the action control signal to the motor 1 of the drive component according to the output material flow value signal. The controller can also output the pulverized coal supply status signal to the pulverized coal supply module of the coal tower according to the output material flow value signal.

[0047] In one embodiment, laser radar sensors can be installed on both sides of the discharge end of the shaking feed hopper 4. The laser radar sensors are connected to the controller signal. The controller receives the sensing signal from the laser radar sensor and outputs the drop volume value signal, which can effectively realize the drop volume and calculate the drop volume more accurately.

[0048] Therefore, the material flow detection device for the shaking feeder in the coking process tamping station provided in this application has low modification cost, can achieve non-contact detection, and has high reliability.

[0049] This application uses a multi-point detection sensor to detect the feeding and dropping surface. The controller (PLC) divides the multiple points and calculates the material flow value and the percentage of the material flow detection result. It also provides feedback on the percentage data of the single dropping volume, thereby ensuring uniform feeding at each frequency, ensuring the uniformity of coal cake growth, and assisting in the judgment of coal cake growth height.

[0050] This application uses a proximity sensor to detect the feeding frequency of the shaking feeder, thereby enabling the counting of feeding times during the tamping process and avoiding the problem of poor material uniformity caused by differences in feeding frequency.

[0051] The material flow detection device for the shaking feeder in the coking process tamping station provided in this application can reduce the number of workers required for the material flow detection function of the tamping station, reduce the degree of manual involvement and labor costs, and is one of the essential implementation factors for realizing unmanned operation of the tamping station.

[0052] This application uses proximity sensors to detect the feeding frequency of the feeder and multi-point detection sensors to detect the percentage of material flow results, thereby determining and recording the cumulative volume of material flow throughout the tamping process. This accurately and reliably determines the real-time material flow size, ensuring uniform feeding by the shaking feeder, uniform material drop, and consistent coal cake forming height, thus improving the quality of coal cake production.

[0053] Example 2

[0054] Based on the material flow detection device for the shaking feeder in the coking process tamping station provided in Embodiment 1 above, this embodiment provides a method for detecting the material flow of the shaking feeder in the coking process tamping station, which mainly includes the following steps:

[0055] S1: The motor 1 of the drive component starts, and drives the connecting rod 3 through the crank. The connecting rod 3 drives the rocking feed hopper 4 to move back and forth. During this period, the coal powder in the coal tower falls into the rocking feed hopper 4. The rocking feed hopper 4 drops material into the coal trough of the coal loading car during the movement.

[0056] For details, see Figure 1 The drive assembly includes a motor 1, a reducer 2 connected to the power output end of the motor 1, a sprocket connected to the output end of the reducer 2, a crank connected to the sprocket via chain drive, and a connecting rod 3 connected to the crank. The connecting rod 3 is connected to the rocking feed hopper 4 via a rocker arm. After the motor 1 is started, the rocking feed hopper 4 is driven through the transmission between the various mechanisms.

[0057] S2: During the reciprocating movement of the shaking feed hopper 4, the feeding cycle of the shaking feed hopper 4 is monitored in real time by the proximity sensor detection component 6. During the falling process of the coal powder in the shaking feed hopper 4, the falling surface and falling time are monitored in real time by the multi-point detection sensor.

[0058] Specifically, the proximity sensor detection component 6 detects the reciprocating movement of the shaking feed hopper 4, records the feeding cycle based on the change in the switch signal of the proximity sensor, and the controller determines the feeding frequency and feeding time based on the feeding cycle, and stores the feeding frequency and feeding time.

[0059] Multi-point detection sensors are used to monitor the material drop surface and drop time in real time. The controller calculates the single-sided area of ​​the material drop based on the sensing signals received from the multi-point detection sensors, and then determines the size of the material flow in a single drop.

[0060] S3: The proximity sensor detection component 6 and the multi-point detection sensor send the detected signals to the controller. The controller calculates the single-sided area of ​​the material and the material flow value of a single drop based on the received signals.

[0061] The detection process for material flow detection using the coking process tamping station shaking feeder material flow detection device provided in Embodiment 1 of this application can be summarized as follows:

[0062] The crank-rocker mechanism of the drive motor of the rocking feeder drives the hopper of the rocking feeder to reciprocate a fixed distance back and forth. The coal powder in the coal tower falls under its own gravity and is fed during the reciprocating motion of the rocking feeder hopper 4. The proximity sensor detection component 6 detects the reciprocating motion of the rocking feeder hopper. One switching quantity is recorded as one feeding cycle. The feeding frequency and time are recorded and determined. During one feeding cycle, three multi-point detection sensors detect the falling surface and provide feedback on the falling time. The controller calculates the single-sided area of ​​the falling material through the processing unit containing the processing program, thereby judging the size of the material flow based on a single falling.

[0063] By combining proximity sensors to monitor the feeding frequency of the shaking feed hopper and multi-point detection sensors to determine the size of each material drop, the controller can effectively calculate the amount of coal powder throughout the entire compaction process.

[0064] The proximity sensor detection component can also monitor the feeding frequency (cycle) to determine whether the tamping motor is malfunctioning and needs maintenance; it can also detect feedback data from multi-point sensors to determine whether the coal tower feeding is abnormal, and if so, it will initiate an abnormality handling procedure.

[0065] This application uses proximity sensors to detect the feeding frequency of the feeder and multi-point detection sensors to detect the percentage of material flow results, thereby determining and recording the cumulative volume of material flow throughout the tamping process. The material flow volume calculation in this application is an estimate, primarily based on the material flow length detection value within a single feeding cycle. The calculation formula is: S = 1 / 2gt 2Where S represents the length of the material flow within a single feeding cycle; t represents the triggering time of the three multi-point detection sensors within a single feeding cycle; and g is the acceleration due to gravity, typically taken as 9.8 m / s². 2 .

[0066] Three multi-point detection sensors are evenly distributed throughout a single feeding cycle to detect the material flow. Therefore, the estimated volume of the material flow in a single feeding cycle is calculated for each of the three multi-point detection sensors, and then summed to calculate and record the total volume of the material flow in a single feeding cycle. By comparing the calculated total volume of the material flow in a single feeding cycle with a threshold, it can be determined whether the material flow size meets the target value.

[0067] In summary, the material flow detection device and method for the shaking feeder in the coking process tamping station provided in this application can be applied to the process monitoring of the tamping station in coal cake forming. It allows for low-cost structural modification of the existing shaking feeder structure, achieving non-contact detection, reducing worker requirements, and lowering manual intervention and labor costs. It scientifically monitors the material flow, detecting the feeding frequency of the feeder through proximity sensors and the percentage of material flow results detected by multi-point detection sensors. This allows for the determination and recording of the cumulative volume of material flow throughout the tamping process, accurately and reliably determining the real-time material flow size, ensuring uniform feeding and material drop, and guaranteeing consistent coal cake forming height, thereby improving coal cake production quality. It effectively solves the problems of inaccurately defined boundaries, errors in judgment, and oversights in manual judgment in existing technologies, and addresses the impact of human factors on the determination of material flow size.

[0068] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
