Description

Technical Field

[0001] The present invention relates to the technical field of dam-building equipment and engineering construction, and particularly to a dam-building equipment system, a control method and their application in the dam-building project by the geomembrane bag method. Background Art

[0002] A geomembrane bag, also known as a geotextile bag, is a structure formed by sewing a woven fabric with a relatively high tensile strength into a bag body of a larger scale, and filling it with a medium slurry such as sediment, dredged bottom mud or tailings by a hydraulic method and then dehydrating it. In the 1950s, the Netherlands first applied geotextile bags in its delta coastal protection project, which greatly saved the cost on the premise of ensuring the project quality. Subsequently, European and American coastal areas such as the United States, Australia and Germany successively adopted geotextile bags as coastal protection structures, and the good application effects attracted the attention of the engineering community. As early as 1985, China introduced geotextile bags into the country and successfully applied them for the first time in the construction project of the ash storage in the Yangtze River Estuary beach of Shanghai Shidongkou Power Plant. Subsequently, geotextile bags have been successively applied to major engineering projects such as the construction of the Qingcaosha Freshwater Storage Reservoir in Shanghai, the regulation of the deep water channel below Nanjing in the Yangtze River, and the construction of the Yangshan Port in Shanghai. While the engineering applications are increasing, the application fields of geomembrane bags are also constantly expanding, from the initial coastal protection to coastal reclamation, and then to engineering fields such as urban sludge treatment, ecological wetland restoration and tailings dam construction in recent years.

[0003] The geomembrane bag method for staged dam building has been continuously promoted and operated in the tailings field, and has gradually been upgraded from simple on-site staged dam building equipment to integrated dam building equipment. However, how to monitor the staged dam building parameters efficiently, accurately, intelligently and economically, enhance the dam building strength and improve the dam building efficiency has become a common concern of engineering technicians and scientific researchers.

[0004] There are mainly two existing geomembrane bag method for staged dam building technologies. One solution is: a simple tailings grading dam building equipment composed of a hydrocyclone, a pump body, a mixing tank, valves and pipelines on-site: This solution mainly relies on manual experience to observe the feed tailings flow rate, viscosity, the fineness of the underflow tailings by hand feeling and the filling height of the geomembrane bag body to judge parameters such as the feed tailings concentration, pressure, flow rate, dilution makeup water volume, underflow tailings concentration and whether the geomembrane bag is filled up.

[0005] In the above solution, during the operation of the equipment, the operation parameters are completely judged based on the experience of the operator. Generally, after one judgment, the operation state will not be adjusted anymore, resulting in inaccurate predicted parameters and unable to meet the requirements of the expected grading effect of the dam building equipment and the filling degree of the geomembrane bag body. This solution makes the quality and quantity of the staged dam building seriously dependent on the experience and responsibility of the operator.

[0006] Another solution is as follows: Install instruments such as flow meters, concentration meters, pressure gauges, and frequency converters on the simple dam-building equipment. Observe the readings of the instruments during the operation of the equipment, compare them with the target parameters, and when they are inconsistent, manually adjust the slurry inlet valve, water supply valve, and the frequency of the slurry pump by hand to ensure that the equipment can operate precisely according to the expected parameters. At the same time, it is still necessary to judge the filling degree of the bag body and whether to switch the filling of the mold bag according to the observed filling height of the mold bag body.

[0007] Although simple monitoring instruments and meters have been installed on the equipment in the above solution, it is necessary for the on-duty personnel to analyze and judge in a timely manner whether to modify the parameters. When the amount of ore pulp fluctuates or the dam-building working conditions change, all parameters need to be recalculated and corrected with the readings of the instruments and meters. At the same time, manually adjust the slurry inlet valve, water supply valve, etc. There are problems such as inaccurate grading dam-building parameters and large personnel investment during the working condition adjustment period. And to ensure the continuous operation of the dam-building equipment, it requires personnel to take turns on duty 24 hours a day, resulting in an increase in construction costs. At the same time, the filling degree of the mold bag body still needs to be judged manually by the on-site workers, which will affect the consolidation speed of the mold bag body in the later stage when the filling degree requirements are not met.

[0008] In view of the above deficiencies of the existing technology, it is very necessary and urgent to research and develop a dam-building equipment system, which can achieve the effects of automatic slurry mixing, slurry grading, and controllable filling degree while realizing the monitoring of the operation parameters of the entire filling process and the real-time correction of parameters, thus effectively alleviating the problem that the existing mold bag method grading dam-building equipment cannot control the operation parameters in real time and accurately.

[0124] Wherein, the system control module interacts with the slurry regulation and stirring module, the slurry classification control module, the filling and conveying switching module, and the pipeline cleaning module through corresponding signals to monitor and adjust the full-process operation parameters of the dam building equipment system;

[0128] The pipeline cleaning module regulates and controls the cleaning of the pipeline in the filling pipeline 413 under the equipment shutdown or emergency stop condition through corresponding signals.

[0129] In this embodiment, the above control system 1 of the present invention utilizes the system control module to interact with the slurry regulation and stirring module, the slurry classification control module, the filling and conveying switching module, and the pipeline cleaning module through corresponding signals to monitor and adjust the full-process operation parameters of the dam building equipment system.

[0130] In this embodiment, the control system 1 further includes a remote control and data analysis module. The remote control and data analysis module interacts with the system control module through corresponding signals, and thus can remotely monitor, adjust, and analyze the operation data of the equipment around the clock, ensure the accuracy of data collection, and at the same time can realize the normal control operation of the equipment in extreme weather conditions, weakening the influence of environmental factors on the dam building efficiency.

[0131] As shown in Figure 6 and Figure 7 shown, in this embodiment, the dam building equipment system further includes a remote control device 6, which is composed of a remote information receiver 61, a network server 62, a network cable and a data connection line 63, a remote control server 64, and a data analyst 65.

[0132] Among them: the remote information receiver 61 receives the signal transmitted back by the remote information transmitting base station 116 on the equipment site; the network server 62 provides the network and stores data; the network cable and the data connection line 63 connect the network server 62 and the remote control server 64, and the remote control server 64 analyzes the received data and remotely issues instructions to control the on-site operation of the equipment through the on-site system control module; the data analyst 65 remotely conducts data analysis and judgment.

[0133] The specific working method of the dam building equipment system for the bagged dam building method in this embodiment is as follows:

[0134] (1) Automatic start: The control system 1 starts when it meets the self-starting conditions;

[0135] (2) Normal operation process: After the control system 1 starts, the electric gate valve 22 and the mixing device water supply electric valve 212 are opened to the set opening degree, the switching electric valves 411 and 42 are opened to 100%, when the liquid level of the slurry dilution mixing tank 214 reaches the preset starting liquid level, the slurry delivery pump 31 starts and the water supply electric valve 317 is opened to the set opening degree, when the liquid level value of the underflow dilution mixing tank 322 reaches the preset starting liquid level, the filling pump 45 starts, and the mixing device water supply electric valve 212 and the water supply electric valve 317 automatically adjust the opening degree according to the concentration value required by the control system 1 until the calculated concentration of the slurry in the slurry dilution mixing tank 214 and the underflow dilution mixing tank 322 is consistent with the measured values of the slurry concentration meter and the tank liquid level meter 27 and the underflow concentration meter and the tank liquid level meter 313, and then maintain the valve opening degree to operate. During the normal operation process, when the pressure value monitored by the pipeline pressure gauge 412 on the filling pipeline 413 reaches the set pressure value, the filling pump 45 increases the frequency through the frequency controller 46 to accelerate the discharge of materials. After the liquid level of the underflow dilution mixing tank 322 drops to the set value, the electric valve 42 is closed, the overflow cleaning electric valve 58 is opened, and the cleaning timing starts. After the set cleaning time ends, the overflow cleaning electric valve 58 is closed and the switching electric valve 411 is switched to perform the filling work. When the monitored pressure value reaches the set pressure value, the control system 1 judges whether the dam building work is completed. If not, continue to perform the cleaning and switch to the filling pipeline 413 according to the above steps, and so on until the end.

[0136] (3) Set preset values according to production information: In the control system 1, the value of the required dam building production capacity can be input. After the input is completed, the system will compare the measured value of the flow rate of the slurry electromagnetic flowmeter 24 with the set value and automatically adjust the opening degree of the electric gate valve 22 through PID until the measured value is consistent with the set value. During operation, if the incoming slurry volume in the raw material introduction pipeline 21 fluctuates, the system will also automatically adjust the opening degree of the electric gate valve 22 through PID to always ensure that the measured value of the slurry electromagnetic flowmeter 24 is consistent with the set input value, realizing the artificial real-time control and adjustment of the dam building production capacity.

[0137] (4) During the cyclone classification process, if it is necessary to modify the cyclone classification efficiency, the classification requirement parameters can be input into the control system 1. The system automatically adjusts the opening degree of the water supply electric valve 212 of the stirring device through PID to change the cyclone classification concentration, and adjusts the frequency of the incoming slurry delivery pump through the pump body frequency converter 32 to adjust the classification pressure and flow rate, realizing the precise and real-time control and adjustment of the cyclone classification concentration and pressure.

[0138] (5) Handling of fault alarms: The operating frequency of the pump body is PID-controlled by the monitored slurry liquid levels in the slurry dilution stirring tank 214 and the underflow dilution stirring tank 322. When the monitored slurry liquid levels in the slurry dilution stirring tank 214 and the underflow dilution stirring tank 322 are greater than the highest critical value or less than the lowest critical value, the system prompts an alarm, increases or decreases the existing operating frequency through the pump body frequency converter 32, and at the same time adjusts the electric gate valve 22 and the water supply electric valve 212 of the stirring device to ensure that the slurry liquid levels in the slurry dilution stirring tank 214 and the underflow dilution stirring tank 322 are stable at about 70 cm, and the slurry delivery pump 31 and the filling pump 45 operate stably at about 40 HZ.

[0139] (6) Emergency stop disposal and flushing: When the equipment pump body stops rotating, the liquid level is high and does not decrease, and the valves and flowmeters are stuck for a long time, etc., the system emergency stop program will be triggered to complete the emergency stop disposal. When the pressure value monitored by the pipeline pressure gauge 412 on the filling pipeline 413 reaches the set pressure value and the liquid level of the underflow dilution stirring tank 322 drops to the set value, the electric valve 42 is closed, the overflow cleaning electric valve 58 is opened, and the cleaning timing starts. After the set cleaning time ends, the overflow cleaning electric valve 58 is closed. After the monitored pressure value reaches the set pressure value, the control system 1 judges whether the dam building work is completed. If not, continue to clean according to the above steps, and so on, until it ends.

[0140] (7) Remote control: The remote information receiver 61 will receive the signals transmitted by the remote information transmitting base station 116 on the equipment site. The network server 62 provides the network and stores the data. The remote control server 64 analyzes the received data and remotely issues instructions to control the on-site operation of the equipment through the on-site system control module. The data analyst 65 conducts data analysis and judgment remotely.

[0141] In summary, a dam-building equipment system provided by the present invention, through the collaborative setting of the slurry stirring device 2, the slurry grading device 3, and the filling and conveying device 4, can achieve the effects of automatic slurry preparation, slurry grading, and controllable filling degree for the materials to be stirred. At the same time, the above control system 1 is interconnected with the slurry stirring device 2, the slurry grading device 3, and the filling and conveying device 4 through corresponding signals. Through the transmission and interaction of signals, the effects of monitoring the operating parameters of the entire filling process and real-time correction of parameters can be achieved, effectively alleviating the problem that the existing graded dam-building equipment using the geomembrane bag method cannot control the operating parameters in real time and accurately.
