Description

Technical Field

[0001] The present application relates to the technical field of coal mine equipment, and in particular to a coal bunker, a coal bunker control system, a control method, equipment and a medium. Background Art

[0002] Coal bunkers are needed for buffer storage in coal production. When the coal bunker is compacted and even blocked, it will seriously affect the efficiency of the raw coal silo. The main reason is that the moisture generated during the coal mining process will enter the coal bunker with the raw coal. Due to long-term use, the coal bunker is prone to arch blockage and condensate forms on the bunker wall. The presence of condensate leads to the obstruction of coal flow, thus greatly reducing the effective storage capacity of the coal bunker. When the moisture in the bunker reaches a certain level, the fluidity of the raw coal in the bunker will increase, and the coal chute gate will be difficult to control, which is very likely to cause bunker collapse accidents, endangering the safety of personnel and equipment.

[0003] 1. Causes of warehouse collapse accidents

[0004] (1) Underground mining operations generate a large amount of geological water and production water. Water and coal are transported into the coal bunker along the belt, forming a water-coal mixed layer in the coal bunker. Due to the increased fluidity and rapid displacement of water-coal, when coal is placed into the water-coal mixed layer, the coal flow surges out instantly, and the gate of the coal chute is difficult to control, which can easily cause bunker collapse.

[0005] (2) During the storage and transportation of coal, improper handling operations may cause the coal level in the coal bunker to rise, resulting in excessive pressure on the coal chute, which may easily cause bunker collapse.

[0006] (3) The raw coal entering the warehouse is loose, which increases the fluidity of the coal and can easily cause warehouse collapse.

[0007] 2. Causes of the warehouse blockage accident

[0008] (1) The concrete or steel plates on the inner wall of the coal bunker are rusted and deformed, which increases the friction coefficient. Coal accumulates on the wall for a long time, and the coal storage diameter at the coal chute and the effective volume in the bunker are rapidly reduced, which easily leads to blockage in the bunker and is the most difficult to clean.

[0009] (2) Large pieces of coal and gangue in the coal bunker gather in the conical section at the bottom of the coal bunker, which can easily cause blockage.

[0010] (3) During the mining and transportation process, a large amount of debris enters the coal bunker along with the coal flow, which easily causes blockage.

[0011] Therefore, in order to ensure normal safe production of coal bunkers, the coal bunkers must be thoroughly cleaned within a certain production cycle; and the cleaning technology of coal bunker facilities is particularly important.

[0012] 1. Current methods of dealing with warehouse congestion

[0013] (1) Use artificially connected bamboo poles and tube explosives to blast open the blocked warehouse.

[0014] (2) Use high-pressure water jets to clear the blockage. The disadvantages of these two methods are that it is impossible to determine the specific location of the blockage. Workers standing under the coal chute, if they fail to evacuate in time during blasting or high-pressure water jets, can easily cause safety accidents.

[0015] 2. Current methods of dealing with wall hanging

[0016] (1) Manually hang into the warehouse and use pneumatic picks and other tools to manually break the arch and clean the wall.

[0017] (2) The existing method uses a high-speed rotating shaft installed vertically in the warehouse, and relies on centrifugal force steel whip (or iron chain) to clean the wall, which is cumbersome and complicated and cannot handle warehouse blockage.

[0018] (3) Using a rotary twist drill to clean walls and break blockages is inefficient, difficult to locate, and cannot be cleaned thoroughly. Summary of the invention

[0043] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0044] The coal bunker, coal bunker control system, control method, equipment and medium of the embodiments of the present application are described below with reference to the accompanying drawings.

[0045] Specifically, Figure 1 A block diagram of a coal bunker provided in an embodiment of the present application.

[0046] like Figure 1 and Figure 2 As shown, the coal bunker 10 includes: a coal bunker body 110 , an inner lining 120 and an anti-blocking bunker clearing device 130 .

[0047] Among them, the lining 120 is fixed to the inner wall of the coal bunker body 110 by an embedded fixing device, wherein the fixing device and the lining 120 are made of ultra-high molecular weight polyethylene modified composite sheet material, which is used to prevent coal from hanging on the wall and blocking the bunker; the anti-blocking and clearing device 130 is arranged at the target position of the conical section at the lower part of the coal bunker body, and is used to use the instantaneous release of high-pressure gas to produce blasting and vibration effects to clean up the coal bunker compaction, loose coal and blockage.

[0048] It can be understood that the embodiment of the present application can use ultra-high molecular weight polyethylene modified composite sheet as the lining to prevent coal from hanging on the wall and blocking the bunker. The anti-blocking and clearing device at the target position of the conical section in the lower part of the coal bunker is used to utilize the instantaneous release of high-pressure gas to produce blasting and vibration effects to clean up the coal bunker compaction, loose coal and blockage, thereby effectively preventing and handling coal bunker blockage and bunker collapse accidents, and preventing people from approaching dangerously. It has the characteristics of safety, efficiency and intelligence, ensures the normal use and maintenance of the coal bunker, and greatly reduces safety hazards.

[0049] It should be noted that if Figure 3As shown, the fixing device and the lining 120 are made of ultra-high molecular weight polyethylene modified composite sheet material, which is used to prevent coal from hanging on the wall and blocking the bin, wherein the fixing device may include: bolts and anchor bolts.

[0050] Specifically, the inner wall is lined with an ultra-high molecular weight polyethylene modified composite material PAES sheet. The sheet is manufactured using nanotechnology with a high technological content and is a new type of composite flame-retardant, high-strength and wear-resistant material. The sheet has a low friction coefficient, extremely high wear resistance, excellent self-lubrication, strong impact resistance, high and low temperature resistance, low water absorption, chemical corrosion resistance, and strong environmental adaptability. Under strong external forces and high heat conditions, its rigidity and heat resistance are strong. Due to its unique composite structure, it has strong anti-aging properties and a very high service life, which is 3-5 times that of ordinary sheets. Using this sheet as the inner wall lining of the coal bunker can prevent sticking, blocking, reduce noise, facilitate construction and installation, save maintenance costs, etc. Among them, as shown in the friction coefficient comparison table in Table 1, the friction coefficient of the PAES sheet is low. Figure 2 As shown in the wear rate comparison table, PAES sheet has extremely high wear resistance.

[0051] Table 1 Friction coefficient comparison table

[0052] Material PAES Board-Coal Super high plate-coal Nylon 66-Coal Cast Stone Slab-Coal Steel Plate-Coal Cement Board-Coal Friction coefficient 0.07-0.11 0.1-0.2 0.37 0.3-0.45 0.45-0.58 0.6-0.8

[0053] Table 2 Wear rate comparison table

[0054] Material PAES board Nylon 66 Polytetrafluoroethylene 45# Carbon Steel Cement Board Average wear rate% 0.3-0.45 1.51 1.72 4.02 4.05

[0055] The installation and construction of PAES board in coal bunker is also very convenient. Because the specific gravity of PAES board is small (0.94-0.98), the weight is only about 1 / 7 of the steel plate of the same specification. Therefore, the lining area can be enlarged and the thickness can be increased to reduce the joints between lining boards, improve the integrity of the bunker wall and extend the service life of the lining board. In order to make the lining board connection smoother and firmer, convex and concave structures can be processed on the side of the lining board, such as Figure 3 As shown in the figure, when the inner lining plates of the coal bunker are connected, the convex groove of each lining plate is inserted into the groove of another plate, which can ensure the flatness of the coal bunker wall, reduce the friction of coal flow, and prevent bunker blockage. In the steel cylinder coal bunker, the PAES plate can be clamped and fixed with special embedded bolts made of the same material or stainless steel, such as Figure 3 As shown in the figure, in concrete coal bunkers or underground excavated coal bunkers, PAES panels can be fixed with special embedded anchor bolts made of the same material or stainless steel, such as Figure 3 As shown, the inner wall of the PAES liner is flatter and smoother than other fixing methods, and the coal flow is smoother.

[0056] In the embodiments of the present application, Figure 2 As shown, the anti-blocking and clearing device 130 includes: a detonation device and a gas booster.

[0057] Among them, the gas booster is connected to the detonation device to provide a high-pressure gas source for the detonation device.

[0058] It can be understood that in the embodiment of the present application, the gas booster provides a high-pressure gas source for the detonation device, and the detonation device utilizes the instantaneous release of high-pressure gas to produce explosion and vibration effects.

[0059] It should be noted that at the appropriate position of the conical section at the bottom of the coal bunker, there is a pre-installed detonation device that uses the instantaneous release of high-pressure gas to produce blasting and vibration effects. The power of these devices all comes from the high-pressure gas source (gas booster). The low-pressure gas is pressurized to the required high pressure before use. The high-pressure boosting chamber of the booster pump adopts oil-free lubrication, and the high-pressure seal contains carbon fiber and has a self-lubricating function. The booster contains intelligent pressure control, which can set the pressure as needed. It will automatically stop working when the set pressure is reached, and automatically start when the pressure drops to the lower level of the set pressure.

[0060] In the embodiments of the present application, Figure 5 As shown, the detonation device includes: a drilling and blasting machine, a detonation ring and a detonator.

[0061] Among them, the drilling and blasting machine is set at the target position outside the lower conical section of the coal bunker, which is used to control the drilling and blasting machine to perform target operations according to actual needs; the detonation ring and the detonator are respectively set inside the lower conical section of the coal bunker and at the lining joint position. Among them, the detonation ring is an annular structure, which is used to produce an instantaneous detonation effect when high-pressure gas is introduced, and through conversion control, high-pressure water can also be introduced to lubricate and flush the bunker wall and flush the blocked coal; the detonator is a monomer structure, which uses the instantaneous release of high-pressure gas to produce blasting and vibration effects, which is used to clear the blockage in the coal bunker.

[0062] It can be understood that the embodiments of the present application can utilize the detonation device to prevent bunker blockage accidents. The detonation ring and the detonator device can be started at a fixed time and pressure to keep the coal flow smooth at all times to prevent long-term coal accumulation from becoming compacted and hanging on the wall. When dealing with bunker blockage accidents, these detonation devices can be controlled separately according to different bunker blockage types, locations, severity, etc. to carry out effective and thorough cleaning.

[0063] Specifically, the detonation ring and the detonator device can be pre-buried inside the lower conical section and at the liner joint position, such as Figure 2As shown. The detonation ring is an annular structure, which can be arranged on the inner wall of the conical section of the lower part of the coal bunker at different conical surface fractions according to the situation. Each circle can be arranged in sections or in an open loop. The detonation ring can not only pass high-pressure gas to produce detonation effect, but also pass high-pressure water to lubricate and flush the bunker wall and flush the blocked coal through conversion control. The shock absorber is a monomer structure and can be arranged at different parts of the inner wall of the conical section. They all use the instantaneous release of high-pressure gas to produce blasting and vibration effects. In order to prevent bunker blockage accidents, the detonation ring and shock absorber devices can be started at a fixed time and pressure to keep the coal flow smooth at all times to prevent long-term coal accumulation from hardening and hanging on the wall; when dealing with bunker blockage accidents, these detonation devices can be controlled separately according to different bunker blockage types, locations, severity, etc. for effective and thorough cleaning.

[0064] In the embodiments of the present application, Figure 4 As shown, the drilling and blasting machine includes: a frame, a drilling and blasting head, a drilling and blasting rod and a push rod device.

[0065] Among them, one end of the drilling head is fixedly connected to the drilling rod, and the other end of the drilling rod is connected to the push rod device, which is arranged at the end of the frame; the front end of the drilling head has all the functions of an ordinary drill bit, and a double air chamber is arranged inside to control the rotation of the drill bit and release high-pressure gas detonation.

[0066] It can be understood that in the embodiment of the present application, when the coal bunker is blocked, the push rod device pushes the drilling rod and the drilling head from the inner wall of the coal bunker to drill into the blocked coal. When the specified position is reached and the pressure is increased to the set pressure, the release valve is opened and the high-pressure gas explodes instantly, thereby achieving the cleaning of the compacted coal bunker, loose coal, and blocked coal bunker.

[0067] Specifically, in a steel cylinder coal bunker or concrete coal bunker, several drilling and blasting machines are pre-set at appropriate locations outside the lower conical section, such as Figure 2 As shown in FIG. 1 , the drilling and blasting machine is composed of a frame, a drilling and blasting head, a drilling and blasting rod and a push rod. Figure 3 As shown. The drilling head has a self-drilling structure. The front end has all the functions of an ordinary drill bit. There are double air chambers inside to control the rotation of the drill bit and release high-pressure gas for detonation, so as to achieve continuous high-pressure blasting without pulling out the rod. When the coal flow is normal, the drilling head retreats to the inner wall of the coal bunker; when the bunker is blocked, the push rod pushes the drilling rod and the drilling head from the inner wall of the coal bunker to the inside of the blocked coal. When the specified position is reached and the pressure is increased to the set pressure, the release valve is opened, and the high-pressure gas is instantly blasted, which can realize the cleaning of coal bunker compaction, loose coal, and blocked bunker.

[0068] According to the coal bunker proposed in the embodiment of the present application, an ultra-high molecular weight polyethylene modified composite sheet is used as the inner lining to prevent coal from hanging on the wall and blocking the bunker. The anti-blocking and bunker-clearing device at the target position of the conical section in the lower part of the coal bunker is used to utilize the instantaneous release of high-pressure gas to produce blasting and vibration effects to clean up the compaction, loose coal and blockage of the coal bunker, thereby effectively preventing and handling coal bunker blockage and bunker collapse accidents, ensuring the normal use and maintenance of the coal bunker, and greatly reducing safety hazards.

[0069] Next, the coal bunker control system proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0070] Figure 6 It is a block diagram of a coal bunker control system according to an embodiment of the present application.

[0071] like Figure 6 As shown, the coal bunker control system 20 includes: a coal bunker 10, a sensor component 210, a visual recognition component 220 and a server 230.

[0072] Among them, the sensor component 210 is arranged inside the coal bunker 10, and is used to collect internal parameters of the coal bunker; the visual recognition component 220 is arranged at the entrance and exit of the coal bunker 10, and is used to monitor the working status of the coal bunker 10 and the monitoring information within a preset range of the coal bunker 10 in real time; the server 230 communicatively connected to the sensor component 210 and the visual recognition component 220 is used to generate corresponding control strategies according to the internal parameters of the coal bunker 10, the working status of the coal bunker 10 and the monitoring information within the preset range of the coal bunker 10, and control the corresponding target components to perform target operations.

[0073] It can be understood that the embodiments of the present application can prevent and deal with coal bunker blockage and collapse, prevent people from dangerous approaching, and utilize sensor components, visual recognition components and servers to achieve intelligent, real-time and safe efficient management of coal bunkers without the need for personnel to be on-site for monitoring, analysis and judgment, and without the need for personnel to be on-site for accident handling.

[0074] It should be noted that the server of this application can be an AI computing server. Sensors such as moisture, coal position, pressure, gas, and carbon monoxide are installed inside the intelligent coal bunker. Visual recognition systems such as infrared cameras, perspectives, peepholes, electronic fences, and electronic access control are installed at the upper and lower openings of the coal bunker. Through AI intelligent monitoring, comparison, and computing power analysis, it is determined whether the coal bunker needs preventive treatment or accidental treatment, and a treatment plan and specific implementation details are proposed. At the same time, the control center and the DCS control system are uploaded to start the relevant detonation mechanism and equipment for treatment. After the treatment is completed according to the plan, the AI ​​intelligent system evaluates the treatment effect and re-proposes suggestions for the next step.

[0075] The moisture sensor, AI visual peep device, coal level sensor, gas sensor, etc. in the coal bunker are linked with the pressure sensor at the coal chute and the AI ​​visual monitoring system data under the coal bunker for linkage control. Data analysis is performed on the AI ​​computing power server to provide early warning and give problem-solving suggestions based on the problems that arise. The DCS control system starts the relevant detonation mechanisms and equipment for processing (opening the detonation ring, detonator, or a drill blaster in a certain direction, or spraying water, or closing the coal discharge gate to control the coal discharge speed, etc.).

[0076] Infrared electronic fences and electronic access control are installed within a certain range above the coal bunker and below the coal feeder. When people approach, early warnings and warnings are issued; when people enter, the AI ​​visual monitoring system compares the images with the database to identify and upload the information data of the illegal operators.

[0077] All monitoring equipment and sensors in the bunker must meet explosion-proof standards, have reliable working performance, and have built-in scour protection performance to adapt to the harsh environment of the coal bunker; the upper feed port and the lower coal discharge port of the underground silo are arranged at different levels, and real-time, delay-free high-speed communication must be established to achieve integrated monitoring of the upper and lower parts of the entire coal bunker.

[0078] Specifically, the moisture sensors, AI visual peep devices, coal level sensors, gas sensors, etc. in the coal bunker are linked with the pressure sensors at the coal chute and the AI ​​visual monitoring system data under the coal bunker for control. Data analysis is performed on the AI ​​computing server to provide early warnings and give solutions based on the problems that arise. The DCS control system starts the relevant detonation mechanisms and equipment for processing, such as: turning on the detonation ring, detonator, or drilling and blasting machine in a certain direction, or spraying water, or adjusting the coal release gate to control the coal release speed, etc.

[0079] In the embodiments of the present application, Figure 2 As shown, the sensor assembly 210 includes: a moisture sensor, a coal level sensor, a pressure sensor, a gas sensor and a carbon monoxide sensor.

[0080] Among them, moisture sensors are installed at intervals inside the coal bunker to monitor the coal flow status in the bunker and the moisture content of raw coal at each level in real time; coal level sensors are used to measure the coal inventory in the coal bunker; pressure sensors are installed at the coal chute of the coal bunker to monitor the pressure change data inside the coal bunker and at the coal chute; gas sensors are used to monitor the methane gas concentration in the coal bunker; and carbon monoxide sensors are used to measure the carbon monoxide concentration in the coal bunker.

[0081] It can be understood that the sensor component in the embodiment of the present application can monitor the working status of the coal bunker in real time, such as moisture, coal level, pressure, gas, carbon monoxide, etc., so as to upload it to the server for processing according to relevant parameters, thereby realizing intelligent, real-time and safe efficient management of the coal bunker.

[0082] It should be noted that all monitoring equipment and sensors in the bunker must meet explosion-proof standards, have reliable working performance, and have built-in scour protection performance to adapt to the harsh environment of the coal bunker. The upper feed port and the lower coal discharge port of the underground silo are arranged at different levels, and real-time, non-delay high-speed communication must be established to achieve integrated monitoring of the upper and lower parts of the entire coal bunker.

[0083] Specifically, moisture sensors are installed at intervals inside the coal bunker to monitor the coal flow status in the bunker and the moisture content of raw coal at each level in real time. A curve change diagram is formed on the AI ​​computing server, and real-time images of the coal flow status at each level are uploaded at the same time. According to the pressure of the silo and the coal flow speed of the silo, the time for the water-containing coal flow to be released to the coal chute is analyzed and calculated, and an alarm is issued when the moisture content of the coal flow exceeds the limit.

[0084] Pressure sensors are installed at the coal chute to monitor the pressure data of the coal chute in real time and upload the data. The AI ​​computing server analyzes the data and issues an alarm when the parameter value exceeds the limit. The AI ​​computing server analyzes the amount and speed of coal discharged from the coal chute, controls the transportation speed of the coal conveyor in real time, and forms a real-time linkage between coal discharge and coal transportation, thereby improving the efficiency of coal discharge.

[0085] In the embodiments of the present application, Figure 2 As shown, the visual recognition component 220 includes: an infrared camera, a perspective viewer, a peep viewer, an electronic fence and an electronic access control.

[0086] Among them, infrared cameras are used to work in low-light conditions and observe the actual conditions inside and outside the coal bunker in real time; X-ray machines are used to image the inside of the coal bunker using X-rays or other penetrating technologies; peepholes are used to insert into the coal bunker through small holes or slits to view hard-to-reach locations; electronic fences are set up at the entrance of the coal bunker or other areas where access needs to be restricted to prevent unauthorized personnel from approaching or entering; electronic access control is used to control access rights to specific areas.

[0087] It can be understood that the embodiments of the present application can use visual recognition components to prevent and deal with coal bunker blockage and collapse, prevent people from dangerous approach, and achieve intelligent, real-time, and safe efficient management of the coal bunker.

[0088] Specifically, in order to prevent and deal with coal bunker blockage and collapse, prevent personnel from approaching dangerously, and achieve the goal of eliminating the need for personnel to be on-site for monitoring, analysis and judgment, and handling accidents, AI intelligence and DCS (distributed control system) control systems have been established, such as Figure 2 As shown, efficient management of coal bunkers in an intelligent, real-time and safe manner has been achieved.

[0089] Infrared electronic fences and electronic access control are installed within a certain range below the upper and lower coal feeders of the coal bunker. When people approach, early warnings and warnings are issued; when people enter, the AI ​​visual monitoring system compares the images with the database to identify and upload the information data of the illegal operators.

[0090] According to the coal bunker control system proposed in the embodiment of the present application, coal bunker blockage and collapse can be prevented and handled, and personnel can be prevented from approaching dangerously. By utilizing sensor components, visual recognition components, and servers, it is possible to achieve intelligent, real-time, and safe efficient management of coal bunkers without the need for personnel to be on-site for monitoring, analysis, and judgment, and without the need for personnel to be on-site for accidents.

[0091] Figure 7 A flow chart of a control method for a coal bunker control system provided in an embodiment of the present application.

[0092] like Figure 7 As shown, the control method of the coal bunker control system includes the following steps:

[0093] In step S101, the actual conditions of the coal bunker and inside and outside the coal bunker are detected.

[0094] It can be understood that the embodiment of the present application can detect the actual conditions of the coal bunker and inside and outside the coal bunker, so as to perform the next step of operation according to the actual conditions.

[0095] In step S102, if it is detected that the moisture content of the coal flow is higher than the first preset threshold, the coal inventory is lower than the second preset threshold, the pressure change data is higher than the third preset threshold, the methane gas concentration is higher than the fourth preset threshold, the carbon monoxide concentration is higher than the fifth preset threshold, an unrelated person is approaching or the access permission is incorrect, then a corresponding alarm reminder and solution are generated, and the coal bunker control system is controlled to perform the target operation according to the solution.

[0096] Among them, the first to fifth preset thresholds can be set according to actual needs without specific limitation.
