Description

Technical Field

[0001] The present invention relates to the technical field of raw coal transportation, and in particular to a belt conveyor coal spreading and cleaning system, a belt conveyor comprehensive processing system and raw coal processing equipment. Background Art

[0002] In coal mining operations, underground raw coal transportation is one of the core links, and the raw coal belt conveyor is the main means of transportation, and its efficient operation is crucial. However, the existing underground large-angle raw coal belt conveyor design, especially in the case of large inclination angles (such as 28 degrees), frequently encounters coal spillage problems. In particular, when transporting raw coal with high moisture content, the amount of coal spilled can reach tens to hundreds of tons, seriously affecting operational efficiency and safety. This problem is particularly prominent during heavy rains or when the mine water surges sharply, causing the water tank to quickly silt up, thereby affecting the normal drainage function.

[0003] The current method of manually controlling the head gate to release water to flush the coal blocks uses a large amount of water (800 cubic meters in an instant) regardless of the amount of coal spread, resulting in a huge waste of water resources. At the same time, since the water tank is close to the tail of the belt conveyor, the coarse coal sludge after flushing quickly accumulates in the water tank, and needs to be cleaned once every two months on average, requiring a large amount of manpower and material resources every year, and the periodic cleaning operation is inefficient and the labor cost is high. In addition, using the existing treatment method, workers need to frequently perform high-intensity manual operations, such as loading mine cars with forklifts, which is not only labor-intensive, but also poses a high personal safety hazard during the long-term underground operation of multiple people during the water tank excavation process. Moreover, the existing dredging method relies on a submersible slurry pump, but due to the presence of coarse coal blocks, the pump body is severely worn and failures occur frequently, increasing maintenance costs and equipment downtime.

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the following embodiments of the present disclosure are described by specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0027] The mechanization, intelligence and unmanned operation of coal spreading and cleaning in underground high-angle main conveyor belt tunnels and comprehensive treatment of underground coal slurry water are the future development trends. Especially due to the increase in labor costs and the requirements for coal mine safety, the requirements for intelligent coal spreading and cleaning and intelligent water tank excavation are getting higher and higher. When the mine water surge suddenly increases, or the mine water surge is caused by long-term heavy rain, the coarse-grained coal slurry at the bottom of the ditch is washed into the water tank, reducing the effective volume of the water tank. At the same time, the coarse-grained materials bring great trouble to the existing excavation equipment. The water tank excavation work is very difficult and affects normal drainage; how to reduce the frequency of water tank excavation, shorten the one-time excavation time, improve the quality of excavation, automatically enter the water tank for automatic excavation, and excavate at all times, reduce safety hazards, and unmanned or less-manned operation, is a technical problem that coal mines urgently need to solve.

[0028] The conventional design of the underground large-angle raw coal main transport belt conveyor has an inclination angle of within 17 degrees. The prior art provides a raw coal belt conveyor with an inclination angle of 28 degrees. When transporting raw coal, the raw coal belt conveyor often scatters coal, especially when transporting water coal (raw coal with a high moisture content). Dozens or hundreds of tons of raw coal often slide to the tail of the belt conveyor, resulting in a large amount of manual excavation and transportation work. 2 shifts are in production while 1 shift is in maintenance. During maintenance, in order to flush the coal blocks scattered around the underground main conveyor belt with a large inclination angle, the gate valve is manually released from the upstream head, and 800 cubic meters of water are used to flush the coal blocks directly into the water tank at the rear end. The raw coal seepage (about 400 cubic meters / hour), flushing water (about 800 cubic meters in an instant), and gushing water (about 400 cubic meters / hour) flush the coarse particles of coal slime into the water tank. Because the underground water tank is close to the tail of the raw coal conveyor belt, about 150 meters, all the coarse particles enter the water tank, causing the water tank to be silted up in 2 months. It is dug out every 2 months, requiring 21 people per day (7 people per shift, three shifts per day, 21 people per day), and it takes 30 days to complete the cleaning, requiring 630 people each time. The water tank is dug out at least 4 times a year, requiring 2520 people per year.

[0029] The current method for cleaning the water tank is: after the water tank is full, a walking cleaning machine (with a pump) and a filter press are used to enter the tank for processing, and the mixture is stirred evenly by manual assistance, and then pumped to the filter press for filtration, and then transported out by a mine car. There are mainly the following types: (1) Manual shovel cleaning method and loader cleaning method. The main shortcomings are high labor intensity, low work efficiency, high cleaning frequency, long cleaning time, and serious environmental pollution caused by coal slime during transportation. (2) Scraper cleaning method and chain bucket cleaning method. The main shortcomings are serious leakage of the transport mine car, low work efficiency, high cleaning frequency, long cleaning time, and serious environmental pollution caused by coal slime during transportation.

[0030] In summary, the existing technology has the following major problems: 1) The head gate is manually used to release water. No matter how much coal is spread, 800 cubic meters of water are used. The water volume is too large, which causes the water tank to fill up quickly. 2) There are many coarse particles, especially large coal blocks. Workers use forklifts to load mine cars for transportation every day, which is a heavy workload and has high labor intensity for workers; 3) Some coarse particles enter the water tank. When the water tank is cleared, the submersible slurry pump is severely worn, with a high failure rate and high maintenance cost. 4) After the water tank is full, it takes a long time to clear the water tank. Many people are working underground, which poses a personal safety hazard and does not meet the safety requirement of "fewer people means safety, no one means safety". 5) The entire dredging process has high labor intensity, low work efficiency, high labor cost for dredging, and great safety hazards.

[0031] Furthermore, as the mining of minerals gets deeper and deeper, the relative production safety is becoming more and more important, especially in coal mines. The gas contained in the coal is inevitably mixed with the oxygen breathed by the construction workers. When the gas concentration is high, it is easy to explode, which poses a great safety hazard. Due to the existence of gas in coal mines, there are strict explosion-proof requirements for underground equipment, electrical components, control systems, power supplies, electric sparks, etc., but the existing public underground robots do not mention it, and there are no countermeasures. For deep well operations, water seepage and landslides often occur, which seriously endangers the lives of construction workers. It is a development trend to use robots instead of manual operations in dangerous environments. Due to the influence of factors such as gas, light, power supply, explosion-proof, dustproof, waterproof, uneven ground, and changeable and irregular environment in coal mines, there are few studies on underground robots, which is a difficult problem at home and abroad. Simplifying the structure and function of robots to solve a single problem with low investment, low failure rate, safety and reliability is a major research and development direction.

[0032] In summary, the embodiments of the present invention provide a belt conveyor coal spreading and cleaning system and a belt conveyor comprehensive treatment system, which avoid excessive water use and improve the intelligence level of the system.

[0033] To facilitate understanding of this embodiment, a belt conveyor coal spreading and cleaning system disclosed in an embodiment of the present invention is first described. The belt conveyor coal spreading and cleaning system is applied to a raw coal belt conveyor, which is used to transport raw coal underground. Figure 1 FIG. 1 shows a schematic structural diagram of a belt conveyor coal spreading and cleaning system provided by an embodiment of the present invention. Figure 1 As shown, the coal-scattering and cleaning system for a belt conveyor includes a central control system 10, a coal-scattering identification device 11 (such as a camera or other image capturing device) and a coal-scattering flushing device 12, and the coal-scattering flushing device 12 and the coal-scattering identification device 11 are respectively connected to the central control system 10 for communication; the coal-scattering identification device 11 is used to perform image recognition on the process of the raw coal conveyor transporting raw coal, obtain a raw coal transportation image, and send the raw coal transportation image to the central control system 10 for communication; the coal-scattering flushing device 12 is installed at a preset position in the lane where the raw coal conveyor is located, and is used to flush the coal-scattering position of the raw coal conveyor; the central control system 10 is used to receive the raw coal transportation image from the coal-scattering identification device 11, and identify the total amount of coal scattered of the coal-scattering material from the raw coal transportation image; and, based on the total amount of coal scattered, determine the amount of coal-scattering flushing water; the central control system 10 is also used to control the flushing water amount of the flushing device according to the raw coal transportation image.

[0034] The embodiment of the present invention uses the coal-scattering identification device 11 to monitor the raw coal transportation process on the raw coal belt conveyor in real time, and uses image recognition technology to enable the device to detect whether there is coal scattered outside the belt from the captured image, and calculate the total amount of scattered coal materials. According to the total amount of coal scattered obtained by the coal-scattering identification device 11, the system automatically calculates the required amount of flushing water. Furthermore, the coal-scattering flushing device 12 works according to the amount of coal-scattering flushing water to flush the coal-scattering materials to ensure that the scattered coal is thoroughly cleaned up. In this way, excessive water use or insufficient water can be avoided, and the efficiency of water resource utilization can be improved. The embodiment of the present invention realizes automatic monitoring of coal scattering conditions by introducing image recognition technology, which greatly improves the intelligence level of the system.

[0035] In summary, the embodiments of the present invention can clean up scattered coal in a timely and accurate manner, reduce the impact of coal dust on the environment, and improve sanitary conditions in the workplace. The automated scattered coal identification and flushing process reduces the need for manual intervention and improves overall work efficiency. Furthermore, the embodiments of the present invention can also be customized according to the specific needs of different coal mines, with flexible design and easy integration with other existing mine automation systems. The raw coal transportation system of the embodiment of the present invention, which combines image recognition technology and intelligent control strategies, not only solves the problem of coal spillage from large-angle belt conveyors, but also brings higher environmental and economic benefits. It is an innovative solution in modern coal mine production.

[0036] Furthermore, based on the above-mentioned embodiment, the embodiment of the present invention also provides another belt conveyor coal spreading and cleaning system. Figure 2 A structural schematic diagram of another belt conveyor coal spreading and cleaning system provided by an embodiment of the present invention is shown. The above-mentioned coal spreading identification device 11 includes an inspection robot, which is used to perform mobile inspections on the raw coal belt conveyor to obtain a raw coal transportation image of the corresponding position of the raw coal belt conveyor. The inspection robot is installed above the raw coal belt conveyor in the main shaft, and performs back and forth inspections, photographs, and image formation through its own track. The inspection robot can cover the entire length of the raw coal belt conveyor by inspecting back and forth, ensuring comprehensive monitoring without leaving blind spots. During the inspection process, photographs are taken at different positions of the raw coal belt conveyor to obtain raw coal transportation images. The images captured by the inspection robot are transmitted to the processing system in real time, and the transmitted raw coal transportation images are processed and analyzed using a preset image recognition algorithm.

[0037] In the specific implementation, the coal-scattering materials in the raw coal transportation image are identified by a preset image recognition algorithm, and the proportion of the coal-scattering materials in the image is calculated. Based on the proportion of the coal-scattering materials in the image, combined with known parameters such as the belt conveyor size and transportation speed, the total amount of coal-scattering materials is estimated to determine the coal-scattering situation. Further, based on the estimated total amount of coal-scattering, the system automatically calculates the required amount of flushing water to ensure the best cleaning effect and the least water consumption. The coal-scattering flushing equipment 12 includes a gate valve 121 and a flushing nozzle 122. The gate valve 121 is installed on the flushing water pipeline. The central control system is used to control the opening of the gate valve to adjust the flow of flushing water; the flushing nozzle is used to adjust the flow of flushing water according to the opening of the gate valve to flush the coal-scattering position of the underground raw coal belt conveyor. Ensure that the flushing water volume matches the calculated actual required water volume to achieve accurate flushing water volume control.

[0038] In specific implementation, the embodiment of the present invention obtains a preset water consumption value, and determines the amount of water for flushing the coal-spreading material based on the water consumption value and the proportion of the coal-spreading material. The above-mentioned preset water consumption value is a reference value pre-set in the system, which is used to calculate the actual amount of flushing water required. This value can be determined based on historical data, experience or experimental results. Further, the final amount of water for flushing the coal-spreading material is determined based on the proportion of the coal-spreading material in the image. In one embodiment, the preset water consumption value can be used to indicate the amount of water required per square meter. Taking the water consumption value as the amount of water per square meter as an example, assuming that the preset water consumption value is 5 liters / square meter, the proportion of the coal-spreading material (P=0.2), indicating that the coal-spreading material accounts for 20% of the image area). The width of the belt conveyor is (W=2) meters and the length is (L=5) meters. Then, the total amount of coal spread is 2 square meters, then, the current amount of water required is 10 liters. The central control system sends a signal to the gate valve 121 to adjust the opening of the gate valve 121 so that the flushing water volume reaches 10 liters. Through this mechanism, the system can accurately control the amount of flushing water, ensuring the cleaning effect while avoiding the waste of water resources.

[0039] Further, in order to solve the situation where there is too much coal scattered in a local position due to the installation error of the belt conveyor, the coal spreading and flushing equipment 12 of the embodiment of the present invention includes not only a global flushing equipment, but also a local flushing equipment 123. The inspection robot is also used to count the coal spreading positions of the coal spreading materials, and the probability of frequently spreading coal is calculated by means of detection, photography, calculation and other means of the inspection robot. Based on the statistical results, the corresponding coal spreading positions of the coal spreading materials are marked; the controller is also used to receive the marked corresponding coal spreading positions, and control the local flushing equipment 123 to flush the corresponding coal spreading positions. The coal spreading situation can be continuously photographed and recorded in multiple cycles, and the probability of coal spreading at each position is calculated by analyzing the historical data, and the position with a high probability of coal spreading is marked as an area that needs to be flushed with emphasis. In the specific implementation, a high-pressure water gun can be pre-set at the corresponding position, and the position where coal is often accumulated or the coal seam is thick can be regularly flushed in advance to average the coal seam of coal spreading, so as to achieve the effect of flushing to the bottom with a small amount of water. Alternatively, a high-pressure water gun installed on a mobile platform is used, and the controller moves to different coal spreading positions as needed to flush the coal spreading materials. Based on this, the embodiment of the present invention is applicable to various complex working environments. Further, the inspection robot can continue to monitor the effect after flushing to ensure that the coal-scattered materials are thoroughly cleaned. If necessary, multiple flushings can be performed until a satisfactory cleaning effect is achieved.

[0040] Furthermore, in order to reduce the amount of water, the embodiment of the present invention also includes a raw coal isolation mechanism, which is arranged in the area covered by the raw coal belt conveyor, and is used to isolate and process the coal materials scattered by the raw coal belt conveyor. Specifically, the area covered by the raw coal belt conveyor is the ground of the roadway where the raw coal belt conveyor is located. In one embodiment, the raw coal isolation mechanism uses non-stick materials, such as ultra-high molecular weight polyethylene plates with a molecular weight of more than 8 million, to reduce resistance and friction. Based on this structure, the scattered coal can automatically slide to the bottom, further reducing the amount of flushing water.

[0041] In summary, the embodiments of the present invention can automatically monitor the coal spreading situation, and can clean up the coal in a timely and accurate manner, reducing the impact of coal dust on the environment. Based on this, the existing instantaneous 800 cubic meters of water can be reduced to 300 cubic meters, or even lower, and the instantaneous 300 cubic meters of water can be evenly distributed to various time periods of an hour, divided into several sections for abbreviated flushing. The automated coal spreading identification and flushing process reduces the need for manual intervention and improves overall work efficiency.

[0042] Furthermore, based on the above embodiments, the embodiments of the present invention also provide a belt conveyor comprehensive processing system, which includes a material processing system and a belt conveyor coal spreading and cleaning system of any of the above embodiments. The embodiments of the present invention use the belt conveyor coal spreading and cleaning system to identify the coal spreading situation of the raw coal belt conveyor, and flush the coal spreading position based on the coal spreading situation, which not only ensures the cleaning effect but also avoids the waste of water resources. Compared with the traditional method that requires a large amount of water to clean the entire area, this system only flushes the coal spreading area, which significantly reduces the water consumption and energy consumption.

[0043] In addition, the embodiment of the present invention is also designed with a material handling system, through which the large coal blocks larger than 2 mm that roll down from the tail of the raw coal belt conveyor are processed to replace manual labor. The material handling system is installed at the end of the raw coal belt conveyor, and is used to collect and process the coal blocks that slide down from the raw coal belt conveyor. These collected coal blocks can be sent back to the belt conveyor or processed separately, which not only reduces the waste of coal, but also further reduces the required water consumption, realizes the effective recycling of resources, and reduces the loss of raw materials. In summary, the embodiment of the present invention combines inspection robots, image recognition technology and multiple processing equipment to flush and process the coal-scattered materials in the raw coal transportation process, which can not only solve many problems in traditional solutions, but also significantly improve the intelligence level, environmental protection benefits and economic benefits of the system. Furthermore, the belt conveyor comprehensive processing system provided by the embodiment of the present invention has the same technical features as the belt conveyor coal-scattering cleaning system provided by the above embodiment, so it can also solve the same technical problems and achieve the same technical effects.

[0044] In combination with the above embodiments, the present invention also provides another belt conveyor comprehensive processing system. Figure 3 The structure diagram of the belt conveyor comprehensive processing system provided by the embodiment of the present invention is shown. Figure 3 The material processing system includes a screening device 21, an auxiliary conveying device 20 and a processing device 22. The screening device 21 is arranged at the end of the raw coal belt conveyor, one end of which is connected to the auxiliary conveying device 20, and the other end of which is connected to the processing device 22; the end of the auxiliary conveying device 20 away from the screening device 21 is connected to the raw coal belt conveyor; the screening device 21 is used to receive the coal blocks sliding down from the raw coal belt conveyor, and pass the materials that meet the requirements to the processing device 22, and pass the materials that do not meet the requirements to the auxiliary conveying device 20. Correspondingly, Figure 4 The relative position diagram of the belt conveyor integrated processing system is shown in Figure 4 In the embodiment, the coal spill identification device 11 of the belt conveyor coal spill identification system is installed above the roadway of the raw coal belt conveyor to inspect the belt conveyor. The material handling system is arranged at the rear end of the belt conveyor to receive the rolled coal blocks. Among them, the processing device 22 is arranged at the rear end of the screening mechanism. Figure 4 Not shown.

[0045] In the specific implementation, the screening device 21 is responsible for screening the rolled raw coal, separating large coal blocks (such as large coal blocks larger than 2 mm) and other impurities, wherein the coal blocks that fail to pass are transported back to the raw coal belt conveyor through the auxiliary conveying device 20, and the separated coal blocks enter the processing device 22 to remove large coal blocks or other materials that require further processing.

[0046] In an embodiment of the present invention, the screening device 21 includes a screening assembly and a transfer device, and the auxiliary conveying device 20 is arranged at the end of the screening assembly to receive the coal blocks that have not been screened and re-convey them back to the raw coal belt conveyor. The transfer device is arranged at the lower end of the screening assembly, for receiving materials that meet the requirements and transferring the materials to the processing device 22. In one embodiment, the transfer device can be a conveyor belt, which is used to transfer the coal blocks that have passed the screening to the feeding port of the processing device 22 for processing by the processing device 22. In summary, the coal blocks rolling down the raw coal belt conveyor are received and processed by the material processing system, so as to reduce the falling of coal blocks, thereby reducing environmental pollution and reducing water consumption. It can also be processed by the processing device 22 to achieve clean water entering the warehouse.

[0047] Furthermore, the material processing system of the embodiment of the present invention also includes a precipitation comprehensive system, which is a facility for treating liquids containing suspended solid particles (such as wastewater, industrial water, etc.). The precipitation comprehensive system is arranged at the rear end of the processing device 22. In one embodiment, the suspended matter is settled by physical or chemical methods, thereby achieving solid-liquid separation and purifying the water quality. Furthermore, the belt conveyor comprehensive processing system of the embodiment of the present invention can be applied to a variety of scenarios, such as a coal screening station, a coal preparation workshop, or a coal processing production line.
