Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic support dust reduction control, and in particular to a hydraulic support spray dust reduction control method and system. Background Art

[0002] Hydraulic support spray dust suppression is a dust suppression technology widely used in industries such as coal mining. By combining the hydraulic support's control system with a spray system, this technology enables automatic spraying during operations such as coal mining and frame shifting, effectively reducing dust concentration in the air, improving the working environment, and protecting worker health.

[0003] At present, when controlling the spray dust reduction of hydraulic supports, manual control or automatic control of the spray dust reduction when the hydraulic supports are moving is often adopted. This cannot effectively suppress the dust in the environment around the hydraulic supports, and when the spray dust reduction control structure fails, it cannot respond in time, which also greatly reduces the stability of the spray dust reduction control of the hydraulic supports.

[0004] To this end, we proposed a hydraulic support spray dust reduction control method and system. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a hydraulic support spray dust reduction control method and system to solve the above-mentioned technical defects.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A hydraulic support spray dust control method comprises the following steps:

[0007] Step 1: Real-time monitoring of the ambient dust concentration in each height area corresponding to the hydraulic support is performed. When the ambient dust concentration exceeds a preset ambient dust concentration threshold, the spray dust reduction structure on the hydraulic support is controlled to operate to reduce the ambient dust in each height area of the hydraulic support.

[0008] Step 2: When controlling the hydraulic support to move, part of the liquid in the moving control valve enters the upper chamber of the push-pull cylinder to move the support forward, while the other part of the liquid opens the one-way valve, allowing cooling water to pass through the one-way valve to the spray dust reduction structure of the adjacent support, thereby reducing the ambient dust in various height areas of the hydraulic support;

[0009] Step 3: When spraying dust suppression on the environmental dust in each height area corresponding to the hydraulic support, cooling water is introduced into the interior of the primary filter frame through the water inlet, and the rotating frame inside the filter chamber is driven by a motor to rotate clockwise. The cooling water is driven to flow to one side of the primary filter screen by a number of filter scrapers arranged on the surface of the rotating frame. The impurities in the cooling water are filtered through the primary filter screen, and the cooling water passes through the primary filter screen into the interior of the treatment box. After the cooling water passes through the primary filter screen, the impurities in the cooling water are further filtered through the two fine filter frames inside the fine filter frame. The coarse sand layer, fine sand layer and activated carbon layer inside the fine filter frame are used to further remove impurities in the cooling water. Finally, the cooling water that has been finely filtered enters the interior of the water storage chamber. When the spray dust suppression structure is working, the water pump at the bottom of the magnetic water device is used. The cooling water in the water storage chamber is sent into the magnetic water device through the water supply pipe. After the cooling water is magnetized inside the magnetic water device, it is sent to the inside of the nozzle rack through the flexible water guide pipe. The electromagnetic arc plate on the driving end of the adjusting electric cylinder is adjusted to adsorb one side of the atomizing nozzle, and the atomizing nozzle is pushed from the inside of the electromagnetic rack into the inside of the water guide connector. Then, the adjusting pressure block inside the water guide connector is inserted into the inside of the atomizing nozzle. The sliding block drives the adjusting pressure block to slide to one side, and the adjusting pressure block is used to connect the connecting pipe inside the atomizing nozzle with the inside of the water guide connector. At the same time, the driving ends of several micro-electric cylinders inside the water guide connector are matched and connected with several positioning holes on the surface of the atomizing nozzle. The magnetized cooling water is sprayed out by the atomizing nozzle to perform spray dust reduction treatment on the environmental dust.

[0010] Step 4: Compare the water supply flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset water supply flow rate threshold. If the water supply flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset water supply flow rate threshold, then compare the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold. Otherwise, directly generate a spray water supply abnormality signal. When the execution terminal receives the spray water supply abnormality signal, arrange maintenance personnel to inspect and process the fine filter rack inside the processing box.

[0011] Step 5. After comparing the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold, if the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset atomization flow rate threshold, a normal spray state signal is generated; otherwise, a nozzle state abnormality signal is generated. When the execution terminal receives the nozzle state abnormality signal, the atomization nozzle inside the water guide connector is reset inside the electromagnetic frame, and the adjustment frame is controlled to rotate by the output shaft of the servo motor, and the atomization nozzle to be replaced is rotated to the top of the adjustment electric cylinder, and the atomization nozzle is replaced by using the driving end of the adjustment electric cylinder in conjunction with the electromagnetic arc plate;

[0012] Step 6. Compare the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process with the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process. If the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process, then compare the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process with the environmental dust concentration threshold of each height area corresponding to the hydraulic support until the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration threshold of each height area corresponding to the hydraulic support, and stop the operation of the spray dust reduction structure.

[0018] The environmental data monitoring module is used to monitor the environmental dust concentration in each height area corresponding to the hydraulic support in real time, and obtain the environmental dust concentration data in each height area corresponding to the hydraulic support;

[0019] The flow state monitoring module is used to monitor the cooling water flow parameters corresponding to the hydraulic support during the spray dust reduction process in real time, and obtain the cooling water flow parameters corresponding to the hydraulic support during the spray dust reduction process, wherein the cooling water flow parameters include water supply flow and atomization flow;

[0020] The spray state analysis module is used to analyze the cooling water flow parameters corresponding to the hydraulic support during the spray dust reduction process to obtain the spray state signal of the hydraulic support during the spray dust reduction process;

[0021] The dust reduction state analysis module is used to analyze the ambient dust concentration data in each height area corresponding to the hydraulic support to obtain the dust reduction state signal of the hydraulic support during the spray dust reduction process;

[0022] The database is used to store initial environmental dust concentration data in each height area corresponding to the hydraulic support, environmental dust concentration thresholds in each height area corresponding to the hydraulic support, and preset water supply flow thresholds and atomization flow thresholds.

[0023] Preferably, the specific monitoring method for real-time monitoring of the ambient dust concentration in each height area corresponding to the hydraulic support is as follows:

[0024] The hydraulic support is divided into upper, middle and lower height zones. Dust concentration sensors are installed in the upper, middle and lower height zones of the hydraulic support. The dust concentration in the environment is monitored in real time using the dust concentration sensors in the corresponding height zones of the hydraulic support to obtain the dust concentration data in the corresponding height zones of the hydraulic support.

[0025] The specific monitoring method for real-time monitoring of the cooling water flow parameters corresponding to the hydraulic support during the spray dust reduction process is as follows:

The water supply flow rate threshold and the atomization flow rate threshold are both manually set by judging multiple sets of historical data. When the water supply flow rate and the atomization flow rate of the hydraulic support during the spray dust reduction process are both less than the water supply flow rate threshold and the atomization flow rate threshold, it indicates that the spray dust reduction structure is operating abnormally;

[0029] Compare the water supply flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset water supply flow rate threshold. If the water supply flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset water supply flow rate threshold, then compare the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold. Otherwise, directly generate a spray water supply abnormality signal.

[0030] After comparing the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold, if the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset atomization flow rate threshold, a normal spray state signal is generated; otherwise, an abnormal spray state signal is generated.

[0031] Preferably, the environmental dust concentration data in each height area corresponding to the hydraulic support is analyzed in the following specific analysis method:

[0032] After receiving the signal that the spraying state of the hydraulic support is normal during the spray dust reduction process, the environmental dust concentration data of each height area corresponding to the hydraulic support is obtained, and at the same time, the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process and the environmental dust concentration threshold of each height area corresponding to the hydraulic support are obtained. The environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process are compared with the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process. If the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process, the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is compared with the environmental dust concentration threshold of each height area corresponding to the hydraulic support. Until the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration threshold of each height area corresponding to the hydraulic support, it means that the environmental dust concentration in each height area corresponding to the hydraulic support has completed spray dust reduction.

[0033] Preferably, the execution terminal is used to perform maintenance on the abnormal state of the hydraulic support during the spray dust reduction process;

[0036] 1. The present invention removes impurities in the cooling water by performing preliminary filtration and fine filtration on the cooling water entering the nozzle holder, thereby effectively preventing the impurities in the cooling water from clogging the interior of the atomizing nozzle, greatly improving the spray dust reduction effect of the atomizing nozzle on the cooling water, and effectively extending the service life of the atomizing nozzle.

[0037] 2. In the present invention, the magnetized cooling water is sprayed out by an atomizing nozzle to perform a spray dust reduction treatment on the environmental dust. When the atomizing nozzle is replaced, the atomizing nozzle inside the water guide connector is reset inside the electromagnetic frame, and the adjusting frame is controlled to rotate by the output shaft of the servo motor, and the atomizing nozzle to be replaced is rotated to the top of the adjusting electric cylinder.

[0038] 3.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1:

[0049] See also Figures 1 to 7 As shown, a hydraulic support spray dust control method includes the following steps:

[0050] Step 1: Real-time monitoring of the ambient dust concentration in each height area corresponding to the hydraulic support is performed. When the ambient dust concentration exceeds a preset ambient dust concentration threshold, the spray dust reduction structure on the hydraulic support is controlled to operate to reduce the ambient dust in each height area of the hydraulic support.

[0051] Step 2: When controlling the hydraulic support to move, part of the liquid in the moving control valve enters the upper chamber of the push-pull cylinder to move the support forward, while the other part of the liquid opens the one-way valve, allowing cooling water to pass through the one-way valve to the spray dust reduction structure of the adjacent support, thereby reducing the ambient dust in various height areas of the hydraulic support;

[0052] Step 3: When spraying dust suppression on the environmental dust in each height area corresponding to the hydraulic support, cooling water is introduced into the interior of the primary filter frame 4 through the water inlet 6, and the rotating frame 9 inside the filter chamber 8 is driven by a motor to rotate clockwise. The cooling water is driven to flow to one side of the primary filter screen 12 by a plurality of filter scrapers 10 arranged on the surface of the rotating frame 9. The impurities in the cooling water are filtered through the primary filter screen 12, and the cooling water passes through the primary filter screen 12 into the interior of the treatment box 1. After the cooling water passes through the primary filter screen 12, the impurities in the cooling water are further filtered through the two fine filter frames 14 inside the fine filter frame 5. The coarse sand layer, fine sand layer and activated carbon layer inside the fine filter frame 5 are used to further remove impurities in the cooling water. Finally, the cooling water that has been finely filtered enters the interior of the water storage chamber. When the spray dust suppression structure is working, the water storage is pumped into the water storage chamber through the water pump at the bottom of the magnetic water device 16 and the water supply pipe 15. The cooling water inside the cavity is sent to the magnetic water device 16. After the cooling water is magnetized inside the magnetic water device 16, it is sent to the inside of the nozzle rack 2 through the flexible water guide pipe 3. The electromagnetic arc plate on the driving end of the adjusting electric cylinder 23 is adsorbed on one side of the atomizing nozzle 21, and the atomizing nozzle 21 is pushed from the inside of the electromagnetic rack 20 into the inside of the water guide connector 17. Then, the adjusting pressure block 26 inside the water guide connector 17 is inserted into the inside of the atomizing nozzle 21. The adjusting pressure block 26 is driven by the sliding block to slide to one side, and the connecting pipe 22 inside the atomizing nozzle 21 is connected to the inside of the water guide connector 17 by the adjusting pressure block 26. At the same time, the driving ends of several micro-electric cylinders inside the water guide connector 17 are matched and connected with several positioning holes on the surface of the atomizing nozzle 21. The magnetized cooling water is sprayed out by the atomizing nozzle 21 to perform spray dust reduction treatment on the environmental dust.

[0053] Step 4: Compare the water supply flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset water supply flow rate threshold. If the water supply flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset water supply flow rate threshold, then compare the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold. Otherwise, directly generate a spray water supply abnormality signal. When the execution terminal receives the spray water supply abnormality signal, arrange maintenance personnel to repair the fine filter rack 14 inside the processing box 1;

[0054] Step 5: After comparing the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold, if the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset atomization flow rate threshold, a normal spray state signal is generated; otherwise, a nozzle state abnormality signal is generated. When the execution terminal receives the nozzle state abnormality signal, the atomization nozzle 21 inside the water guide connector 17 is reset inside the electromagnetic frame 20, and the adjustment frame 18 is controlled to rotate by the output shaft of the servo motor 19, and the atomization nozzle 21 to be replaced is rotated to the top of the adjustment electric cylinder 23, and the atomization nozzle 21 is replaced by using the driving end of the adjustment electric cylinder 23 in conjunction with the electromagnetic arc plate;

If the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process, then compare the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process with the environmental dust concentration threshold of each height area corresponding to the hydraulic support until the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration threshold of each height area corresponding to the hydraulic support, and stop the operation of the spray dust reduction structure.

[0073] By setting flow sensors inside the water supply pipe 15 and the water guide connector 17, the cooling water flow inside the water supply pipe 15 and the water guide connector 17 is monitored in real time using the flow sensors to obtain the water supply flow and atomization flow of the hydraulic support during the spray dust reduction process.

[0074] The spray state analysis module is used to analyze the cooling water flow parameters corresponding to the hydraulic support during the spray dust reduction process, and obtain the spray state signal of the hydraulic support during the spray dust reduction process. The specific analysis method is as follows:

[0075] The water supply flow and atomization flow are extracted from the corresponding cooling water flow parameters of the hydraulic support during the spray dust reduction process, and the preset water supply flow threshold and atomization flow threshold are obtained from the database. The water supply flow threshold and the atomization flow threshold are both artificially set through evaluation of multiple sets of historical data. When the water supply flow and atomization flow of the hydraulic support during the spray dust reduction process are both less than the water supply flow threshold and the atomization flow threshold, it indicates that the spray dust reduction structure is operating abnormally.

[0076] The corresponding water supply flow rate of the hydraulic support during the spray dust reduction process is compared with the preset water supply flow rate threshold. If the corresponding water supply flow rate of the hydraulic support during the spray dust reduction process is greater than the preset water supply flow rate threshold, the corresponding atomization flow rate of the hydraulic support during the spray dust reduction process is compared with the preset atomization flow rate threshold. Otherwise, a spray water supply abnormality signal is directly generated.

[0077] After comparing the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process with the preset atomization flow rate threshold, if the atomization flow rate corresponding to the hydraulic support during the spray dust reduction process is greater than the preset atomization flow rate threshold, a normal spray state signal is generated; otherwise, an abnormal spray state signal is generated.

[0078] The dust fall state analysis module is used to analyze the ambient dust concentration data in each height area corresponding to the hydraulic support, and obtain the dust fall state signal of the hydraulic support during the spray dust fall process.

[0079] The specific analysis method is as follows:

[0080] After receiving the signal that the spraying state of the hydraulic support is normal during the spray dust reduction process, the environmental dust concentration data of each height area corresponding to the hydraulic support is obtained, and at the same time, the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process and the environmental dust concentration threshold of each height area corresponding to the hydraulic support are obtained. The environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process are compared with the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process. If the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration data of each height area corresponding to the hydraulic support before the spray dust reduction process, the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is compared with the environmental dust concentration threshold of each height area corresponding to the hydraulic support. Until the environmental dust concentration data of each height area corresponding to the hydraulic support during the spray dust reduction process is less than the environmental dust concentration threshold of each height area corresponding to the hydraulic support, it means that the environmental dust concentration in each height area corresponding to the hydraulic support has completed spray dust reduction.

[0081] The early warning module is used to send abnormal spray state signals of the hydraulic support during the spray dust reduction process to the execution terminal for early warning processing.

[0082] The execution terminal is used to inspect and handle the corresponding problems of abnormal conditions of the hydraulic support during the spray dust reduction process.

[0083] The database is used to store the initial environmental dust concentration data in each height area corresponding to the hydraulic support, the environmental dust concentration threshold value in each height area corresponding to the hydraulic support, and the preset water supply flow threshold value and atomization flow threshold value.
