Description

Technical Field

[0001] This utility model relates to the field of mine water tank cleaning technology, and more specifically, to a cleaning device. Background Technology

[0002] During mine operation, sludge accumulates in the mine's water sump. It's crucial to clean the slurry from the sump regularly. Current methods typically involve manual cleaning of the slurry, which includes sludge and water, and then transporting it to mine cars via rails. These cars are then hoisted to the surface by winches and delivered to a surface filter press or a coal washing plant for filtration. This manual cleaning method is inefficient, inefficient in terms of personnel and time, and only suitable for single-level mining. For multi-level mines, equipment needs to be deployed at each level. Frequent starting and stopping of the mine cars during hoisting causes sludge and water to spill out, and this constant starting and stopping poses a significant safety hazard to the system.

[0003] In other words, existing technologies suffer from problems such as low efficiency, high cost, waste of human resources, and high risk in cleaning slurry from water tanks. Utility Model Content

[0004] The main purpose of this utility model is to provide a slurry cleaning device to solve the problems of low efficiency, high cost, waste of human resources, and high risk in cleaning slurry in water tanks in multi-level coal mines in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a slurry cleaning device is provided. This device is used to clean slurry from a water tank in a multi-level coal mine. The water tank in the multi-level coal mine includes a low-level water tank located at a low mining level and a high-level water tank located at a high mining level. The slurry cleaning device includes: a cleaning mechanism located within the low-level water tank; a filter press mechanism located within the high-level water tank; and a connecting pipe, one end of which is connected to the cleaning mechanism and the other end of which is connected to the filter press mechanism.

[0006] Furthermore, the cleaning mechanism includes: a cleaning machine, one end of which has a slurry pool; a first slurry transmission pipe, one end of which extends into the low-level water tank and the other end of which is located in the slurry pool; and a first slurry pump, which is installed on the first slurry transmission pipe to pump the slurry from the low-level water tank into the slurry pool.

[0007] Furthermore, the cleaning machine has a grouting pump located inside the slurry pool, and one end of the connecting pipe is connected to the grouting pump.

[0008] Furthermore, the filter press mechanism includes: a filter press; a mixing tank, the other end of which is connected to the mixing tank via a connecting pipe, a hydraulic component connected to the mixing tank, a slurry transfer component, the mixing tank being connected to the filter press via the slurry transfer component, the slurry transfer component being used to pump the slurry in the mixing tank into the filter press; and a hydraulic component, the hydraulic component being connected to the mixing tank, the hydraulic component being used to provide stirring power to the mixing tank.

[0009] Furthermore, the slurry transfer assembly includes: a second slurry transfer pipe, one end of which is connected to the mixing tank and the other end of which is connected to the filter press; and a second slurry pump, which is installed on the second slurry transfer pipe to pump the slurry in the mixing tank into the filter press.

[0010] Furthermore, the connecting pipeline includes: a first sub-pipeline located in the low-level water tank, one end of which is connected to the grouting pump of the cleaning machine; a second sub-pipeline, the other end of which is connected to the second sub-pipeline; and a third sub-pipeline located in the high-level water tank, one end of which is connected to the mixing tank, and the other end of which is connected to the second sub-pipeline.

[0011] Furthermore, the first sub-pipe and the second sub-pipe are set at an angle, and the second sub-pipe and the third sub-pipe are set at an angle.

[0012] Furthermore, the first and third sub-pipes are flexible hoses, while the second sub-pipe is a metal pipe.

[0013] Furthermore, the cleaning equipment also includes a high-level cleaning component, which is located inside the high-level water tank and is connected to the filter press mechanism. The high-level cleaning component is used to pump the slurry inside the high-level water tank to the filter press mechanism.

[0014] Furthermore, the cleaning equipment also includes a check valve, which is installed on the connecting pipe.

[0015] Furthermore, the cleaning equipment also includes a transport vehicle, which is used to transport the filter cake pressed out by the filter press mechanism.

[0016] The present invention provides a cleaning device for cleaning slurry in a multi-level coal mine.

The cleaning mechanism is located in the low-level water tank, and the filter press mechanism is located in the high-level water tank. One end of the connecting pipe is connected to the cleaning mechanism, and the other end of the connecting pipe is connected to the filter press mechanism. The cleaning mechanism is used to pump the slurry in the low-level water tank into the filter press mechanism.

[0017] By incorporating a cleaning mechanism and a filter press mechanism, the cleaning mechanism draws slurry from the water tank into the filter press mechanism, pressing it into a filter cake.

Furthermore, the cleaning equipment of this application is equipped with a connecting pipe. The cleaning mechanism is located in the lower extraction level water tank, while the filter press mechanism is located in the higher extraction level water tank. The connecting pipe connects the cleaning mechanism in the lower extraction level water tank to the filter press mechanism in the higher extraction level water tank, allowing the cleaning mechanism to pump slurry from the lower extraction level water tank into the filter press mechanism for filtration. This reduces the need for additional material conveying equipment between the cleaning machine and the filter press mechanism, improving cleaning efficiency while simultaneously reducing equipment investment and maintenance costs.

[0028] To address the problems of low efficiency, high cost, waste of human resources, and high risk in cleaning slurry from water tanks in existing multi-level coal mines, this utility model provides a slurry cleaning device.

[0029] like Figures 1 to 4 As shown, the slurry cleaning equipment is used to clean the slurry in the water tank of a multi-level coal mine. The water tank of the multi-level coal mine includes a low-level water tank located at a low mining level and a high-level water tank located at a high mining level. The slurry cleaning equipment includes a cleaning mechanism 10, a filter press mechanism 20, and a connecting pipe 30. The cleaning mechanism 10 is located in the low-level water tank, the filter press mechanism 20 is located in the high-level water tank, one end of the connecting pipe 30 is connected to the cleaning mechanism 10, and the other end of the connecting pipe 30 is connected to the filter press mechanism 20. The cleaning mechanism 10 is used to pump the slurry in the low-level water tank into the filter press mechanism 20.

[0030] By setting up a cleaning mechanism 10 and a filter press mechanism 20, the cleaning mechanism 10 can suck the slurry in the water tank into the filter press mechanism 20 and press it into a filter cake. Compared with manual cleaning and filtration, this effectively improves the cleaning efficiency and the filtration efficiency. In addition, the cleaning equipment of this application is also equipped with a connecting pipe 30. The cleaning mechanism 10 is set in the low-level water tank, while the filter press mechanism 20 is set in the high-level water tank. The connecting pipe 30 connects the cleaning mechanism 10 in the low-level water tank with the filter press mechanism 20 in the high-level water tank, so that the cleaning mechanism 10 pumps the slurry in the low-level water tank into the filter press mechanism 20 for filtration. This reduces the need for additional material conveying equipment between the cleaning machine 11 and the filter press mechanism 20, improves the cleaning efficiency, and reduces equipment investment and maintenance costs.

[0031] Furthermore, the separate design of the cleaning mechanism 10 and the filter press mechanism 20 allows the cleaning work in the low-level water tank to be carried out independently of the filter press work in the high-level water tank. The cleaning mechanism 10 only needs to focus on the collection and initial pumping of slurry, without the need for complex filter press operations in the low-level water tank. This simplifies the cleaning process in the low-level water tank and improves the cleaning efficiency.

[0032] Furthermore, the design of the connecting pipe 30 enables direct connection between water tanks at different levels, allowing slurry to be directly pumped from the lower-level water tank to the filter press 20 at the higher-level water tank. This design avoids repeated slurry transport between different levels, reducing the demand and pressure on transportation equipment. Especially when cleaning operations are performed simultaneously at multiple levels, it effectively prevents transportation congestion and ensures the continuity and efficiency of the cleaning operation. By centrally locating the filter press 20 in the higher-level water tank, the need to install a filter press 20 in each water tank is reduced, optimizing space utilization, reducing equipment density, lowering overall equipment costs, and also reducing safety hazards caused by equipment layout.

[0033] like Figure 2As shown, the cleaning mechanism 10 includes a cleaning machine 11, a first slurry transmission pipe 13, and a first slurry pump 14. One end of the cleaning machine 11 has a slurry pool 12. One end of the first slurry transmission pipe 13 extends into the low-level water tank, and the other end of the first slurry transmission pipe 13 is located in the slurry pool 12. The first slurry pump 14 is installed on the first slurry transmission pipe 13 to pump the slurry from the low-level water tank into the slurry pool 12. The direct pumping action of the first slurry pump 14 reduces the residence time of materials in the first slurry transmission pipe 13, reducing the occurrence of pipe blockage caused by improper sludge-to-water ratio. In addition, the slurry pool 12 can serve as a temporary material storage and adjustment area, which helps to ensure uniform material supply and reduces the occurrence of insufficient material supply. The first slurry pump 14 directly pumps the slurry mixture of silt and water from the low-level water tank into the slurry pool 12 of the cleaning machine 11, avoiding the need for manual or equipment to repeatedly handle materials during the traditional cleaning process, thus significantly improving the efficiency of the cleaning operation. The use of the first slurry pump 14 also ensures the continuity of material supply, avoids intermittent operation of the cleaning machine, and improves the continuity and efficiency of the overall operation.

[0034] In this way, the slurry cleaning machine 11 can operate directly within low-level water tanks, reducing secondary handling of slurry and making it suitable for rapid cleaning of large water tanks. During operation, the efficient operation of the first slurry pump 14 significantly shortens the slurry transport time, thereby accelerating the cleaning speed. This design is particularly important for large water tanks, enabling the cleaning of large amounts of slurry in a short time, improving production efficiency and reducing environmental impact.

[0035] Specifically, the cleaning machine 11 has a grouting pump located inside the slurry tank 12, with one end of the connecting pipe 30 connected to the grouting pump. This configuration allows for direct extraction of a mixture of sludge and water from the slurry tank 12, which is then transported to the next processing stage via the connecting pipe 30. This eliminates the need for additional conveying equipment, such as trackless rubber-wheeled vehicles or winches, between the cleaning machine 11 and the filter press 20, simplifying the material transport process and improving efficiency. Since the grouting pump is directly located inside the slurry tank 12, it ensures continuous and stable material supply, avoiding frequent start-ups and shutdowns due to insufficient supply, and reducing equipment wear and the likelihood of failure. Simultaneously, the direct connection between the connecting pipe 30 and the grouting pump reduces the risk of blockage during material transport, further enhancing system reliability. The grouting pump enables more efficient transport of slurry to high-level water tanks, making it suitable for scenarios with long slurry transport distances. The grouting pump is designed with long-distance transport needs in mind; by optimizing the pump body structure and increasing pumping pressure, it overcomes resistance during long-distance transport, ensuring stable slurry delivery. This capability is particularly crucial in deep-well mining operations, as it effectively solves the problem of transporting slurry from underground to the surface, improving the continuity and efficiency of operations.

[0036] Furthermore, this configuration reduces the need to arrange the filter press mechanism 20 at different mining levels, and also reduces the need for additional material conveying equipment between the cleaning machine 11 and the filter press mechanism 20, thus lowering equipment investment and maintenance costs. At the same time, it effectively increases the level of automation, thereby reducing the need for operators and achieving savings in human resources.

[0037] Optionally, the grouting pump can have an automatic detection function. By placing the pump within the slurry tank, it can automatically detect and maintain the appropriate mixing ratio of sludge and water, ensuring that pipe blockage or pump damage does not occur during transport due to excessively dry sludge or excessive moisture. This automated control method reduces the need for manual intervention, lowers labor costs, and simultaneously improves operational safety and continuity.

[0038] like Figure 3 As shown, the filter press mechanism 20 includes a filter press 21, a mixing tank 22, a slurry transfer assembly 23, and a hydraulic assembly 24. The other end of the connecting pipe 30 is connected to the mixing tank 22. The mixing tank 22 is connected to the filter press 21 through the slurry transfer assembly 23. The slurry transfer assembly 23 is used to pump the slurry in the mixing tank 22 into the filter press 21. The hydraulic assembly 24 is connected to the mixing tank 22 and is used to provide stirring power for the mixing tank 22.

[0039] By incorporating the mixing tank 22, the slurry transported from the low-level water tank can be thoroughly agitated, ensuring a uniform distribution of solid and liquid components. This pretreatment step is crucial for the subsequent filtration process, improving filtration efficiency and filter cake quality, preventing filter cloth clogging or incomplete filter cake formation due to uneven slurry composition, thereby reducing downtime and malfunctions during filtration operations. The mixing tank 22 ensures thorough mixing of the slurry before filtration, enhancing the filtration effect and making it suitable for applications with complex slurry compositions requiring pretreatment. Pretreatment of the slurry with the mixing tank not only improves the filter press's processing efficiency but also extends the equipment's lifespan and reduces maintenance frequency. This design is particularly important for processing slurries containing various solid particles, preventing decreased efficiency and equipment damage caused by uneven particle distribution. The introduction of the hydraulic assembly 24 provides an efficient and stable drive for the mixing tank 22. Hydraulic components 24 typically possess high power output and control precision, ensuring thorough and uniform mixing of the slurry within the mixing tank 22 before filter pressing. They also provide power to the slurry transfer assembly 23, guaranteeing a stable and continuous pumping of the slurry into the filter press 21, further enhancing the efficiency and reliability of the filter pressing operation. The mixing tank 22 is connected to the filter press 21 via the slurry transfer assembly 23. This design ensures direct and continuous slurry transfer from the mixing tank 22 to the filter press 21, reducing losses and potential blockages in intermediate stages and improving the overall efficiency of the slurry transfer process. Simultaneously, the design of the slurry transfer assembly 23 considers the rheological characteristics of the slurry, employing appropriate pumping technology and pipeline design to ensure stable slurry transfer, avoiding material waste and inefficiency issues associated with traditional transfer methods (such as mine car transportation).

[0040] Furthermore, the integrated design of the filter press mechanism 20 tightly integrates the mixing tank 22, the hydraulic components 24 of the hydraulic mechanism, and the slurry transfer components 23 with the filter press 21, reducing the equipment's footprint and optimizing space utilization. Especially in environments with limited space, such as high-level water tanks, this design effectively reduces the difficulty and cost of equipment layout while lowering the complexity of equipment operation and maintenance. The filter press mechanism 20 has a high degree of automation; the slurry transfer process between the mixing tank 22 and the filter press 21 requires no manual intervention, reducing the need for operators, lowering labor intensity, and minimizing errors and safety risks associated with human operation, making the entire cleaning operation safer and more efficient. Slurry is supplied directly to the mixing tank 22 through the connecting pipe 30, and then continuously pumped to the filter press 21 through the slurry transfer components 23, ensuring the continuity of the filter press operation and avoiding interruptions and efficiency fluctuations that may occur in traditional cleaning operations, thus improving operational stability and overall efficiency.

[0041] like Figure 3As shown, the slurry transfer assembly 23 includes a second slurry transfer pipe 231 and a second slurry pump 232. One end of the second slurry transfer pipe 231 is connected to the mixing tank 22, and the other end is connected to the filter press 21. The second slurry pump 232 is installed on the second slurry transfer pipe 231 to pump the slurry in the mixing tank 22 into the filter press 21. The use of the second slurry pump 232 ensures that the uniformly mixed slurry in the mixing tank 22 can be continuously and stably transferred to the filter press 21. Pressure control during the pumping process helps maintain the flow state of the slurry, avoids blockage during the transfer process, and ensures high efficiency and continuity of the transfer. By directly sending the slurry in the mixing tank 22 to the filter press 21 through the second slurry transfer pipe 231, losses and secondary pollution in intermediate links are avoided. When the uniformly mixed slurry enters the filter press 21, it can ensure uniform material distribution during the filtration process, improve the filtration efficiency and the quality of the filter cake formation, and reduce the maintenance frequency of the filter press.

[0042] Furthermore, the second slurry pump 232 ensures the continuity and stability of slurry transmission, making it suitable for industrial environments with continuous operation. The continuous operation of the second slurry pump 232 ensures a stable and continuous flow of slurry into the filter press 21, avoiding efficiency losses caused by discontinuous slurry supply during the filtration process. This design offers significant benefits to industries such as chemical production and ore processing that require continuous slurry processing, effectively improving production efficiency and reducing production costs.

[0043] like Figure 1 and Figure 4As shown, the connecting pipeline 30 includes a first sub-pipeline 31, a second sub-pipeline 32, and a third sub-pipeline 33. The first sub-pipeline 31 is located in the low-level water tank, with one end connected to the grouting pump of the cleaning machine 11; the other end of the first sub-pipeline 31 is connected to the second sub-pipeline 32. The third sub-pipeline 33 is located in the high-level water tank, with one end connected to the mixing tank 22, and the other end connected to the second sub-pipeline 32. The first sub-pipeline 31 connects directly from the low-level water tank to the grouting pump of the cleaning machine 11, ensuring that the slurry can be immediately pumped to the connecting pipeline 30, reducing the residence time of the slurry in the low-level water tank, avoiding secondary sedimentation, and improving the slurry transmission efficiency. The third sub-pipeline 33 ensures that the slurry can be quickly transported to the mixing tank 22 in the high-level water tank, maintaining the continuity and stability of slurry transmission. The environmental conditions of the low-level and high-level water tanks may differ greatly, such as spatial layout, height difference, and pipeline path. By using a segmented connecting pipeline design, the length, diameter, and layout of each sub-pipeline can be flexibly adjusted according to the specific environment of each water tank, optimizing the transmission path and ensuring high efficiency in slurry transmission, while reducing the difficulty and cost of pipeline layout. This pipeline design can adapt to different terrains and spatial layouts, improving the adaptability and flexibility of the equipment. The segmented connecting pipeline design not only enables the equipment to adapt to various terrain changes but also facilitates pipeline installation and maintenance, reducing operational difficulties caused by terrain limitations and improving overall operational flexibility and efficiency.

[0044] like Figure 1 and Figure 4 As shown, the first sub-pipe 31 and the second sub-pipe 32 are set at an angle, and the second sub-pipe 32 and the third sub-pipe 33 are set at an angle. In coal mine water sump environments, especially under complex conditions with multiple mining levels, space is often very limited. Setting the pipes at angles effectively utilizes three-dimensional space, reducing the area occupied by the pipes on a single plane, thereby optimizing the spatial layout of the entire system, leaving more space for other equipment or operations, and improving the flexibility and efficiency of the overall layout of the work site. Furthermore, the angled arrangement between the sub-pipes helps to change the flow direction of the slurry. Through reasonable angle design, the resistance of the slurry at bends can be reduced, improving fluid dynamics characteristics, ensuring smooth flow of the slurry during transmission, reducing energy consumption and pipe wear, and extending the service life of the pipes. For example, the first sub-pipe 31 is perpendicular to the second sub-pipe 32, and the second sub-pipe 32 is perpendicular to the third sub-pipe 33.

[0045] Optionally, the first sub-pipe 31 and the third sub-pipe 33 are flexible hoses, while the second sub-pipe 32 is a metal pipe. Flexible hoses can adapt to complex terrain and equipment layouts, facilitating flexible connections and adjustments between low-level water tanks and cleaning machines 11, as well as between equipment within high-level water tanks. This offers significant advantages in environments with limited working space and frequent equipment layout changes in coal mines. Metal pipes, used in pipelines connecting different mining levels, provide higher structural stability and pressure resistance, effectively resisting the high pressure and geological stress unique to underground coal mines, ensuring safety and stability during long-distance, high-drop transmission. The combination of flexible hoses and metal pipes ensures both pipeline flexibility and enhanced durability, making it suitable for operating environments requiring frequent pipeline layout adjustments. Flexible hoses facilitate quicker and easier pipeline layout adjustments, while metal pipes ensure structural strength and durability. This combined design is particularly suitable for operating environments such as mining and chemical production, effectively addressing the challenges of complex terrain and frequent operations.

[0046] In some alternative embodiments, the cleaning equipment also includes a one-way valve, which is installed on the connecting pipe 30. The most basic function of the one-way valve is to control the unidirectional flow of fluid and prevent reverse flow. Installing a one-way valve on the connecting pipe 30 can effectively prevent the backflow of slurry when the pump stops working or the system pressure fluctuates, avoiding the re-contamination of the low-level water tank by silt, and ensuring the continuity and effectiveness of the cleaning operation.

[0047] If the slurry in the connecting pipe 30 flows back when the filter press 21 stops working or the cleaning equipment malfunctions, it may place an additional burden on the cleaning machine 11, the first slurry pump 14, and the piping system, and may even cause equipment damage. The presence of the check valve reduces this risk and improves the safety of the entire cleaning equipment system.

[0048] In some alternative embodiments, the cleaning equipment also includes a transport vehicle for transporting the filter cake pressed by the filter press 20. The use of the transport vehicle makes the transportation of the filter cake from the filter press 21 at the high-level mining tank to the surface more efficient. Compared to traditional mine cars or rail transport systems, transport vehicles (especially trackless rubber-tired vehicles) have faster transport speeds and larger carrying capacities, reducing the transport time of the filter cake between the surface and underground, and improving the efficiency of the entire cleaning operation. The direct use of the transport vehicle simplifies the logistics process of the filter cake from the filter press 21 to the surface, avoiding multiple transfers and unloading in intermediate stages, making the entire cleaning operation more continuous and smooth. This not only saves time but also reduces filter cake loss and secondary pollution during transportation, improving the overall quality and environmental friendliness of the operation.

[0049] In some alternative embodiments, the transport vehicle includes either a trackless rubber-tired vehicle or a belt conveyor. Trackless rubber-tired vehicles and similar transport vehicles are not limited by fixed tracks, allowing for flexible movement between underground and surface areas, adapting to the complex and varied terrain and environment of coal mines, and improving the flexibility of the slurry handling system. In this utility model patent, when cleaning operations are carried out simultaneously at different mining levels, the transport vehicle can respond quickly without requiring lengthy preparation and adjustments, ensuring the continuity of operations.

[0050] In some alternative embodiments, the cleaning equipment further includes a high-level cleaning component located within the high-level water tank and connected to the filter press mechanism 20. The high-level cleaning component pumps the slurry from the high-level water tank to the filter press mechanism 20. By installing the high-level cleaning component within the high-level water tank, cleaning and filtration of the slurry in both the low-level and high-level water tanks can be performed simultaneously, further improving cleaning efficiency.
