[0024] 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.

[0025] In order to solve the safety hazards caused by water gushing during coal mining, 2-3 water tanks are usually built to store water. Some mines use less water, generally 400-600 cubic meters per hour, but some coal mines use a lot of water, generally 1500-2000 cubic meters per hour. Especially during heavy rains, the mines have a large amount of water gushing, and a large amount of water gushing (an average of 1800 cubic meters per hour) washes the coarse coal slime into the water tank. All the coarse particles enter the water tank, causing the water tank to quickly fill up. The excavation cycle is as short as 2 months, which increases the frequency and urgency of dredging work. A large amount of coarse coal slime, including large pieces of coal, enters the water tank with the water flow, which not only aggravates the siltation rate, but also makes the excavation operation extremely difficult, increasing the manpower demand and labor intensity.

[0026] The current method for clearing 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 transported to the filter press for filtration by a pump, and then transported out by a mine car. However, the existing submersible slurry pump is prone to serious wear and tear, frequent failures, and high maintenance costs due to the processing of coarse particles, which affects the efficiency and economy of dredging. Moreover, the clearing operation requires a large number of people to work in a dangerous underground environment for a long time, which violates the safety principle of "fewer people are safer, and no one is safer", and there are major safety hazards. Moreover, when clearing the water tank, a spare water tank needs to be activated, which poses certain safety hazards. The current clearing methods such as manual shovels, loaders, scrapers, and chain bucket machines are inefficient, labor-intensive, and cause serious environmental pollution. Even if the existing mechanical operation clears the water tank, manual assistance is required, which is time-consuming and labor-intensive and cannot completely solve the problem of clearing the water tank. It is difficult to meet the safety and environmental protection requirements of modern coal mines. Each excavation takes 30 days and requires a large amount of manpower (630 people each time). The total annual labor cost is extremely high, and the frequent manual operations further increase the operating costs.

[0027] In summary, in order to solve the above problems, the embodiments of the present invention provide a comprehensive coal sludge water treatment system and water tank in a coal mine, which can reduce the frequency of water tank cleaning, shorten the one-time cleaning time, and improve the quality of cleaning. It can also achieve the effect of automatic cleaning and real-time cleaning, and can reduce safety hazards and realize unmanned or less-manned operation, solving a major technical problem in the coal mine scene.

[0028] For ease of understanding, first, a coal mine underground coal slurry water comprehensive treatment system provided by an embodiment of the present invention is described, wherein the coal mine underground coal slurry water comprehensive treatment system of the embodiment of the present invention is arranged at the front end of a preset water tank. In one embodiment, a tunnel can be excavated at the front end of the water tank, and the coal mine underground coal slurry water comprehensive treatment system of the embodiment of the present invention is arranged based on the tunnel, so as to pre-treat the particulate materials in the water body, and the water body particles do not enter the water tank, which solves the safety hazard problem of entering the tank. Among them, the coal mine underground coal slurry water comprehensive treatment system of the embodiment of the present invention includes a plurality of water treatment branches, and the water treatment branches are arranged side by side along the direction of water flow. The embodiment of the present invention simplifies the treatment process by changing a large amount of water into a small amount of water, so that the treatment capacity of each branch is equivalent to the water consumption of a general mine, which is easier to manage and control. Taking 1,800 cubic meters / hour of water as an example, when there are three water treatment branches, the flow rate of each branch is about 600 cubic meters / hour.

[0029] in, Figure 1 FIG. 1 shows a schematic diagram of a comprehensive treatment system for coal sludge water in a coal mine provided by an embodiment of the present invention. Figure 1As shown, each water treatment branch includes a first material treatment system and a second material treatment system, and the first material treatment system and the second material treatment system are arranged in sequence along the direction of water flow. Among them, the coal mine underground coal slurry water comprehensive treatment system of the embodiment of the present invention is arranged at the front end of the preset water tank. In one embodiment, a tunnel can be excavated at the front end of the water tank, and the coal mine underground coal slurry water comprehensive treatment system of the embodiment of the present invention is arranged based on the tunnel, so as to pre-treat the particulate material in the water body, and the water body particles do not enter the water tank, which solves the safety hazard problem of entering the tank. Among them, the coal mine underground coal slurry water comprehensive treatment system of the embodiment of the present invention includes a plurality of water treatment branches, and the water treatment branches are arranged side by side along the direction of water flow. The embodiment of the present invention simplifies the treatment process by changing a large amount of water into a small amount of water, so that the treatment capacity of each branch is equivalent to the general mine water consumption, which is easier to manage and control. Taking 1800 cubic meters / hour of water as an example, when there are three water treatment branches, the flow rate of each branch is about 600 cubic meters / hour.

[0030] in, Figure 1 FIG. 1 shows a schematic diagram of a comprehensive treatment system for coal sludge water in a coal mine provided by an embodiment of the present invention. Figure 1 As shown, each water treatment branch includes a first material processing system 10 and a second material processing system 20, and the first material processing system 10 and the second material processing system 20 are arranged in sequence along the water flow direction. Among them, the first material processing system 10 includes a dredging device 101 for processing coarse particles in the mud. The second material processing system 20 includes a sedimentation tank 201, and a filter press 202 arranged at a preset position of the sedimentation tank 201. Figure 1 Multiple water treatment branches are distinguished by water treatment branch a, water treatment branch b, and water treatment branch c. The sedimentation tank 201 is used for sedimentation treatment of the coal slurry water output by the first material treatment system 10, and the filter press 202 is used for filter pressing treatment of the coal slurry water after sedimentation. In specific implementation, for gushing water with a large amount of coarse particles, the embodiment of the present invention designs a first material treatment system 10 and a second material treatment system 20, including a clearing device 101, a sedimentation tank 201, and a filter press 202, which not only performs sedimentation treatment on the gushing water to gradually settle the suspended matter to the bottom of the tank, but also treats particulate materials of different particle sizes in the water to meet the discharge standards.

[0031] In summary, the embodiment of the present invention provides a comprehensive treatment system for coal sludge water in coal mines. Through the combination of the first material processing system 10 and the second material processing system 20, the graded treatment of materials with different particle sizes is realized, and the treatment efficiency is improved. Moreover, the modern excavation equipment 101 and the filter press 202 have a high level of automation, which reduces manual intervention and improves safety. In addition, the particles in the gushing water can be effectively treated by the above-mentioned method, and the clean water can be put into the warehouse, which can reduce the frequency of the water warehouse being full, thereby reducing the frequency of excavation. Moreover, the excavation efficiency can be improved, the one-time excavation time can be shortened, and the impact on production can be reduced. It can also ensure that the excavation is thorough, avoid residual coal sludge water from affecting subsequent production, and improve the quality of excavation. In addition, the embodiment of the present invention does not require manual assistance, can be unmanned or less manned, and supports remote control to realize the operation of the ground control room above the well, reduce the demand for personnel underground, and reduce the potential safety hazards of excavation. It can achieve the effect of automatic cleaning and cleaning at all times, solving a major technical problem in the coal mine scene.

[0032] Furthermore, based on the above-mentioned embodiment, the embodiment of the present invention also provides another comprehensive treatment system for coal slurry water in coal mines. Among them, the second material processing system 20 also includes a slurry pump 203, which is arranged in the cavity of the sedimentation tank 201; the output end of the slurry pump 203 is connected to the input end of the filter press 202; the slurry pump 203 is used to transport coal slurry water materials to the filter press 202. For finer materials, the coal slurry water treated by the first material processing system 10 (i.e., the excavation equipment 101) is pumped into the filter chamber of the filter press 202, and the filter press 202 applies pressure to the filter chamber to force the liquid to be discharged through the filter cloth or filter screen, and the solid particles are trapped on the filter cloth to form a filter cake. Continue to apply pressure and further dehydrate to achieve solid-liquid separation of coal slurry water. Among them, the second material processing system 20 is equipped with a monitoring system, which is used to monitor the processing process parameters of the coal slurry water, including the flow, pressure and concentration of the coal slurry water; the monitoring system communicates with a preset controller, and the controller is used to control the pumping rate of the mud pump 203 based on the processing process parameters.

[0033] Further, the second material processing system 20 also includes a deep cone thickener, and the bottom flow of the deep cone thickener is connected to the input end of the mud pump 203; the deep cone thickener is used to settle the coal slurry water and output the high-concentration bottom flow of the coal slurry water, so as to transport the high-concentration bottom flow to the filter press 202 through the mud pump 203. In the specific implementation, the gushing water enters multiple water treatment branches, and the water volume of the gushing water is distributed by multiple water treatment branches. The gushing water flows through the cleaning equipment 101 in turn, and the coal slurry water (or other gushing water) is cleaned by the equipment. The mud (i.e., fine materials) after cleaning enters the sedimentation tank 201, and the deep cone thickener processes the mud. The deep cone thickener uses its special structure (cylindrical upper part and conical bottom) to allow solid particles to settle to the bottom under the action of gravity, and the clarified liquid is discharged from the upper overflow port. Further, the deep cone thickener is equipped with a dosing device. In one embodiment, the dosing device is arranged at the input end of the deep cone thickener. Among them, flocculants such as PAM (polyacrylamide) and PAC (polyaluminium chloride) are arranged in the dosing device. PAM and PAC are added as flocculants while feeding. PAM helps to increase the coagulation effect of particles, while PAC can improve the stability and sedimentation rate of flocs. In specific implementation, the above-mentioned controller is also used to control the dosage of the dosing device based on the treatment process parameters of the slurry (i.e., coal slurry water), and improve the solid-liquid separation efficiency through flocculation and sedimentation, so as to obtain a higher concentration of underflow and clearer overflow water. The underflow of the concentrator is pumped to the filter press 202 for treatment, so as to realize the storage of clean water.

[0034] In one implementation, the mud pump 203 may be a centrifugal mud pump 203, a piston mud pump 203, a diaphragm mud pump 203, a screw mud pump 203, or a plunger mud pump 203, and the mud is extracted or transported through corresponding stirring or extraction mechanisms, so as to transmit the mud to the filter press 202. In an embodiment of the present invention, the mud pump 203 is a submersible mud pump 203. Furthermore, in an embodiment of the present invention, a stirring blade may be provided at the input end of the mud pump 203, and the stirring blade and the pump body motor may be coaxially installed to simultaneously stir the mud during the operation of the pump body. The input end of the mud pump 203 is arranged toward the bottom of the sedimentation tank 201, and the output end may be arranged above it, and the high-concentration underflow may be pumped to the filter press 202 due to the pump body pressure.

[0035] Further, the mud pump 203 may be provided with multiple output ports, one of which is connected to the filter press 202, and the other output ports may be used as the flushing end of the sedimentation tank 201, and the opening and closing of each output port is controlled by the controller to realize the different pumping functions of the mud pump 203. Further, the sedimentation tank 201 of the embodiment of the present invention may be a multi-stage sedimentation tank 201 structure, and multiple sedimentation tanks 201 are arranged in sequence along the direction of water flow, and the overflow of the current sedimentation tank 201 enters the sedimentation tank 201 behind to treat the gushing water in multiple stages. Further, each water treatment branch may also be provided with multiple second material treatment systems 20 side by side along the direction of water flow, that is, in each water treatment branch, the gushing water after the branch is further diverted. In one embodiment, a single sedimentation tank 201 may be a tank structure with a length of 10 meters and a width of 2 meters, wherein it may be a deep cone sedimentation tank 201. Corresponding to the embodiment of the present invention, each water treatment branch may be provided with two rows side by side along the direction of water flow, and 8 sedimentation tanks 201 may be provided in each row. It should be noted that the size and number of sedimentation tanks 201 are designed based on the processing capacity, the settling speed of the suspended matter, the required residence time and the specific process requirements. Figure 2 The schematic diagram of the structure of another comprehensive treatment system for coal sludge water in coal mines provided by an embodiment of the present invention is shown. Figure 2 In the figure, a top view of the second material processing system 20 of a single water processing branch is mainly illustrated. Figure 2 The mud pump 203 is arranged in the sedimentation tank 201, and the output end of the mud pump 203 is located at the side end thereof, and is used to communicate with the filter press 202 ( Figure 2 Correspondingly, the position of the deep cone concentrator is set based on the demand.

[0036] Furthermore, in order to improve processing capacity, reduce the load of a single machine, and improve reliability, there are multiple cleaning devices 101 in the embodiment of the present invention, and the multiple cleaning devices 101 are connected in sequence along the direction of water flow, which can achieve the effect of step-by-step filtration, reduce the risk of clogging of subsequent equipment, and ensure the smooth operation of the entire system. Among them, each cleaning machine is responsible for processing a portion of coarse particles in the mine water, and can focus on processing particles in a specific particle size range, which can improve the overall processing efficiency, and achieve more refined graded processing, and improve the processing effect. Moreover, it can also reduce the load of a single device, extend the service life of the equipment, and reduce maintenance costs. If a cleaning machine fails, other cleaning machines can still continue to work, and will not cause the entire system to shut down completely, thereby improving the reliability and stability of the system. Furthermore, the working parameters of each cleaning machine can be flexibly adjusted according to actual needs to meet the needs of different working conditions. Correspondingly, Figure 3The schematic diagram of the structure of a dredging device 101 provided by an embodiment of the present invention is shown. The figure illustrates the connection structure of multiple dredging devices 101. The number and arrangement order of dredging devices can be designed according to the actual flow rate of the water body and the composition of the particulate matter. In the embodiment of the present invention, four dredging devices connected in series can be designed, and two are used as an example.

The flow meter is communicatively connected to a preset PLC control system module; the PLC control system module is used to control the opening of the branch gate valve and the water volume based on the flow rate detected by the flow meter, so as to evenly distribute the water to each water treatment branch for easy processing.

[0039] Furthermore, the first material handling system 10 is also equipped with a monitoring system module, which is added to important corners of the equipment to monitor the equipment in the first material handling system 10. The monitoring system of the second material handling system 20 is similar. The staff can observe in the control room at all times, handle faults in time, and improve operation efficiency.

[0040] Furthermore, a pressure sensor is provided in each water treatment branch, and the water treatment branch is also equipped with an air supply system; the pressure sensor is communicatively connected to a preset PLC control system module; the PLC control system module is used to control the air supply volume of the air supply system based on the sensing value of the pressure sensor to ventilate the water treatment branch. Among them, the air supply volume can be determined by the computing center system control module to achieve ventilation of the water treatment branch (such as the lane), ensure that the gas meets the standard, and ensure the normal operation of the robot. Furthermore, the embodiment of the present invention is also designed with an intelligent remote maintenance system module, through which the user is promptly guided to perform maintenance, improve the working efficiency of the equipment, and reduce energy consumption.

[0041] In summary, in the embodiment of the present invention, a tunnel can be excavated at the front of the water tank and a multi-branch structure can be set in the tunnel to form multiple water treatment branches.
