Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology in mining, and in particular to an automatic water spraying and dust suppression device for dry tailings ponds. Background Technology

[0002] Tailings dams, as an important supporting facility in the mineral processing process, are mainly used to store tailings slag and wastewater generated during mineral processing. The dry beach is the tailings accumulation area exposed above the water surface in the tailings dam. Because the tailings particles are exposed for a long time and the surface is dry, they are prone to generating a large amount of dust under the action of wind. According to the "Integrated Emission Standard of Air Pollutants" and local environmental protection requirements, the daily average concentration of TSP (total suspended particulate matter) around the tailings dam should be ≤120μg / m³. However, if the dust from the dry beach is not controlled, its concentration often exceeds the limit by 1.2-1.8 times. This not only pollutes the surrounding atmospheric environment and endangers the health of workers, but may also affect the normal production and operation of the mine. Therefore, dust control on the dry beach has become one of the core requirements for the operation and maintenance of tailings dams. Existing surface-laid fixed devices involve laying main and branch pipes directly on the surface of dry land and controlling water spraying via manual valves or simple timers. While simple in structure and low in cost, they have significant drawbacks: Firstly, dry land has a natural slope, and surface pipes are prone to elevation differences due to tailings accumulation. This results in insufficient water pressure from sprinklers at the top of the slope and excessive spraying from sprinklers at the bottom due to water flow convergence, creating a 10%-20% dust suppression blind zone. Secondly, since the pipes are in direct contact with tailings, newly discharged tailings can easily bury branch pipes and sprinklers, requiring frequent excavation and adjustment. This not only interferes with tailings discharge operations but also accelerates pipe corrosion and incurs high maintenance costs. Utility Model Content

[0022] Please see Figure 1-7 This utility model provides a technical solution: an automatic water spraying and dust suppression device for dry tailings ponds, including an overhead support system and a pipeline conveying system. The pipeline conveying system is set on top of the overhead support system and is distributed in a mesh pattern. The overhead support system includes a precast concrete base 1, a main support 2, a hot-dip galvanized angle steel support 3, a secondary support 4, and embedded bolts 5; The pipeline transportation system includes PVC-U branch pipes 8, PVC-U main pipes 9, main pipe clamps 11, and branch pipe clamps 12; If the precast concrete base 1 is set in a pre-reserved pit on the dry beach and is evenly spaced according to the dry beach area, the main support 2 is set on the top of the precast concrete base 1, the pre-embedded bolts 5 are set at the center of the top of the precast concrete base 1, the hot-dip galvanized angle steel support 3 is fixedly connected to the top surface of the precast concrete base 1 and fixed by the pre-embedded bolts 5, the other side of the hot-dip galvanized angle steel support 3 is fixedly connected to the main support 2, and the auxiliary support 4 is fixedly connected between the tops of the two opposing main supports 2. The auxiliary support 4 and the main support 2 form a gate-shaped structure. The main pipe clamp 11 is fixedly connected to the top of the main support 2. The branch pipe clamps 12 are fixedly connected to the top of the auxiliary support 4 at equal intervals. The PVC-U main pipe 9 is fixedly connected to two opposing main pipe clamps 11. The main pipe clamps 11 are located at both ends of the PVC-U main pipe 9. The PVC-U branch pipes 8 are fixedly connected to the branch pipe clamps 12. Several PVC-U branch pipes 8 and PVC-U main pipes 9 form a network distribution. A branch pipe solenoid valve 13 is fixedly connected at the intersection of the PVC-U branch pipes 8 and the PVC-U main pipes 9. The branch pipe solenoid valve 13 is a ZCS type PVC solenoid valve, a water supply on / off control component, installed at the intersection of the PVC-U main pipe 9 and the branch pipes 8, to precisely control the water supply to each branch pipe. The specifications are adapted to the branch pipes. The diameter and nominal pressure of 1.6MPa meet the system pressure requirements, and the 0.5s rapid response ensures timely start of dust suppression. The bottom of the PVC-U branch pipe 8 is fixedly connected to an atomizing fan-shaped nozzle 10, which is evenly distributed along the axis of the PVC-U branch pipe 8. The atomizing fan-shaped nozzle 10 is a TYP-120 type atomizing fan-shaped nozzle, which is the core component of the spraying execution. It is fixed at the bottom of the PVC-U branch pipe 8 and installed at a 30° angle. It compresses the water transported by the branch pipe into a mist of 10-50μm through a 1.5mm nozzle. The 120° fan-shaped coverage ensures that the effective coverage width of a single nozzle is 8m. By overlapping adjacent nozzles by 1m and adjacent branch pipes by 2m, dust suppression without blind spots is achieved in the entire dry beach area, while avoiding tailings loss caused by water erosion. All PVC-U main pipes 9 are connected by pipes. A horizontal centrifugal pump 14 is installed on one side of the device. The horizontal centrifugal pump 14 is an ISW ​​type horizontal centrifugal pump, which is a water source power component. The input end is connected to the external water supply pipe, and the output end is connected to the main water inlet of the PVC-U main pipe 9. The impeller is driven to rotate by a 1.5kw motor, which pressurizes the external water source to 0.15MPa to ensure that the water source can be delivered to the entire dry beach area with a length of 80m and a width of 40m. At the same time, the copper impeller is wear-resistant and can adapt to the slight impurities that the external water supply may contain. The output end of the horizontal centrifugal pump 14 is connected to the main water inlet pipe of the PVC-U main pipe 9. A sensor base 18 is installed on the top of the main support 2 located in one corner of the device. The sensor base 18 is fixedly connected to the secondary support 4. A wind speed sensor 17 is fixedly connected to the top of the sensor base 18. The wind speed sensor 17 is a model FC-6S wind speed sensor, a dust risk monitoring component, fixed on the top of the sensor base 18. Three nylon wind cups capture the real-time wind speed. A sensor bracket 16 is installed at the bottom of the sensor base 18. The sensor bracket 16 is fixedly connected to the main support 2. A humidity sensor 15 is fixedly connected to the sensor bracket 16. The humidity sensor 15 is a model SHT30 temperature and humidity sensor, an environmental monitoring component, fixed on the sensor bracket 16. The front faces the dry beach and collects the surface air humidity of the dry beach in real time. A display screen is installed on the humidity sensor 15 for data observation. The humidity sensor 15 is equipped with an electrical control cabinet bracket 7 at its bottom. The electrical control cabinet bracket 7 is located on one side of the main bracket 2. An outdoor rainproof electrical control cabinet 6 is fixedly connected to the electrical control cabinet bracket 7. The outdoor rainproof electrical control cabinet 6 is a GGD type outdoor rainproof cabinet with an IP54 protection rating. It has a built-in S7-200SMART PLC to control the start and stop of the horizontal centrifugal pump 14 and the branch solenoid valve 13. It is equipped with a manual / automatic switching button and status indicator lights, supports fault alarms, and stores operating data for easy maintenance and troubleshooting.

[0023] Working principle: The environmental monitoring function of the device is jointly realized by the humidity sensor 15 and the wind speed sensor 17. The two are fixed together to ensure the accuracy of the monitoring data. The wind speed sensor 17 is fixed on the top of the sensor base 18 and can capture the real-time wind speed in the dry beach area without obstruction. The humidity sensor 15 is fixed on the sensor bracket 16 with its front facing the dry beach. It collects the humidity of the surface air of the dry beach in real time. The humidity sensor 15 also has a built-in display screen, which can intuitively view the real-time data. The humidity sensor 15 and the wind speed sensor 17 collect analog signals, such as humidity and wind speed values, and transmit them to the outdoor rainproof electrical control cabinet 6 via cables. The outdoor rainproof electrical control cabinet 6 has a built-in PLC controller with preset dust suppression trigger thresholds: when the wind speed is ≥5m / s or the humidity is ≤60%, the PLC controller determines that dust suppression needs to be started and generates a device start trigger signal; when the wind speed is ≤3m / s and the humidity is ≥70%, a device stop signal is generated. The horizontal centrifugal pump 14 is located on one side of the device. Its input end is connected to the external water supply pipe, and its output end is connected to the main water inlet pipe of the PVC-U main pipe 9 through a pipe. After receiving the start signal from the outdoor rainproof electrical control cabinet 6, the horizontal centrifugal pump 14 is powered on and runs, pressurizing the external water source and delivering it to the PVC-U main pipe 9. The PVC-U main pipe 9 is fixed to the top of the main support 2 by the main pipe clamp 11. The main support 2 is supported by the precast concrete base 1. The precast concrete base 1 is reinforced by the pre-embedded bolts 5 and the hot-dip galvanized angle steel bracket 3 to ensure overall stability. All PVC-U main pipes 9 are connected by pipes to form the main channel for main water inlet and branch transportation. The pressurized water flows along the PVC-U main pipe 9 and is evenly distributed to the main pipe branches throughout the dry beach area, preparing for subsequent diversion to branch pipes. A branch solenoid valve 13 is fixedly connected at the intersection of PVC-U branch pipe 8 and PVC-U main pipe 9. The branch solenoid valve 13 is connected to the outdoor rainproof electrical control cabinet 6 via a cable. When a start signal is received, the outdoor rainproof electrical control cabinet 6 simultaneously sends an opening command to all branch solenoid valves 13. The branch solenoid valve 13 is energized and opened, releasing the passage restriction between PVC-U main pipe 9 and PVC-U branch pipe 8. The PVC-U branch pipes 8 are fixed to the top of the secondary support 4 at equal intervals by the branch pipe clamps 12. The secondary support 4 is connected to the opposite main support 2 to form a gate-shaped structure, ensuring the horizontal stability of the branch pipes. Several PVC-U branch pipes 8 and PVC-U main pipes 9 form a network distribution. The opened branch pipe solenoid valve 13 introduces the water source in the main pipe into the PVC-U branch pipe 8. The water source flows along the branch pipe and is evenly delivered to each spray point. The atomizing fan-shaped nozzle 10 is fixed at the bottom of the PVC-U branch pipe 8 and is evenly distributed along the axis of the branch pipe. Its 120° opening angle and 30° downward tilt angle can ensure that the water flow spreads in a fan shape. When the water source in the branch pipe flows through the nozzle, it is squeezed and transformed into fine atomized particles of 10-50μm, which not only avoids the loss of tailings caused by water flow, but also efficiently captures suspended dust. Because the PVC-U branch pipes 8 are distributed at equal intervals, and the atomizing fan-shaped nozzles 10 are installed at equal intervals, and the water spraying range of adjacent nozzles and adjacent branch pipes overlaps, the dry beach is ultimately 100% covered without any dust suppression blind spots. When the outdoor rainproof electrical control cabinet 6 receives a stop signal, it sequentially closes the branch pipe solenoid valve 13 and the horizontal centrifugal pump 14, and the device stops running, completing one automatic dust reduction cycle. If manual operation is required, the start and stop of each device can be directly controlled through the manual / automatic switching button of the outdoor rainproof electrical control cabinet 6 to adapt to special working conditions.

[0024] Structural Description: Precast concrete base 1: Set in a pre-reserved pit on the dry beach and evenly spaced according to the dry beach area. The top is used to install the main support 2 and the pre-embedded bolts 5. It can provide stable bottom support for the entire overhead support system, and prevent the device from shifting as a whole due to uneven dry beach ground or external forces. At the same time, the even arrangement ensures a balanced distribution of support force, ensuring the stability of subsequent component installation. Main support 2: Set on top of precast concrete base 1, the top is used to install main pipe clamps 11, and the side is connected to hot-dip galvanized angle steel brackets 3. The top of the two opposing main supports 2 is also connected to auxiliary supports 4. As the vertical core support component of the overhead support system, it can raise the pipeline transportation system and other auxiliary components to a position away from the dry beach surface, avoiding tailings accumulation from burying or damaging the components. At the same time, it provides a reliable installation carrier for each horizontal component, ensuring the vertical stability of the overall structure. Hot-dip galvanized angle steel bracket 3: One end is fixed to the top surface of the precast concrete base 1 by pre-embedded bolts 5, and the other end is fixedly connected to the main bracket 2. The triangular support structure enhances the connection strength between the main bracket 2 and the precast concrete base 1, reduces the tilting and swaying of the main bracket 2 caused by the top load or wind force. At the same time, the hot-dip galvanized material can adapt to dry and humid environments, reduce the risk of corrosion, and extend the service life of the components. Sub-support 4: It is fixedly connected between the tops of the two opposing main supports 2, forming a portal structure together with the main supports 2. The top is used to install the branch pipe clamp 12. The portal structure can enhance the lateral stability of the overhead support system, prevent the main supports 2 from deforming in the lateral direction, and provide a horizontal installation foundation for the branch pipe 8, ensuring that the branch pipe 8 can remain horizontal and ensuring the uniformity of subsequent water supply. Embedded bolt 5: Set at the center of the top of the precast concrete base 1, used to fix the hot-dip galvanized angle steel bracket 3. It can firmly lock the hot-dip galvanized angle steel bracket 3 onto the precast concrete base 1, prevent the connection between the two from loosening, ensure the stability of the triangular support structure, and thus provide a guarantee for the stability of the entire overhead support system, avoiding component displacement due to connection failure. Outdoor rainproof electrical control cabinet 6: Fixed on the electrical control cabinet bracket 7, it integrates control components to receive sensor signals and control the start and stop of the horizontal centrifugal pump 14 and the branch solenoid valve 13. It is also equipped with a manual / automatic switching button, status indicator lights and fault alarm function. As the control core of the device, it can realize centralized management and control of various components. The manual / automatic switching function can adapt to different working conditions. The fault alarm function can facilitate the timely detection of equipment abnormalities. The rainproof design can adapt to dry outdoor environment and prevent rainwater from entering and damaging internal components. Electrical control cabinet bracket 7: Located on one side of the main bracket 2, the top is used to fix the outdoor rainproof electrical control cabinet 6. It can raise the outdoor rainproof electrical control cabinet 6 to a position away from the dry beach ground, so as to avoid the dry beach water from soaking the cabinet or the tailings dust accumulation affecting the heat dissipation of the cabinet. At the same time, it puts the electrical control cabinet in a position that is easy for maintenance personnel to operate and observe, thus improving the convenience of maintenance. PVC-U branch pipe 8: It is fixed to the top of the auxiliary support 4 by the branch pipe clamp 12, and crosses with the PVC-U main pipe 9 to form a network distribution. The branch pipe solenoid valve 13 is installed at the intersection, and the atomizing fan-shaped nozzle 10 is installed at the bottom. The network distribution can realize the water supply coverage of the entire dry beach area, ensuring that each sprinkler point can obtain water. The PVC-U material has good corrosion resistance and can adapt to the dry beach environment, avoiding damage to the pipe due to tailings water erosion. At the same time, the branch pipe structure facilitates precise control of the watering situation in each area. PVC-U main pipe 9: It is fixed to the top of the main support 2 by the main pipe clamp 11. All PVC-U main pipes 9 are connected by pipes. One end is connected to the output end of the horizontal centrifugal pump 14. It intersects with the PVC-U branch pipes 8 to form a network distribution. As the main channel for water supply, it can evenly distribute the water supplied by the horizontal centrifugal pump 14 to each PVC-U branch pipe 8, ensuring that the water supply of the entire pipeline system is sufficient and the pressure is stable. The PVC-U material has strong corrosion resistance, which can extend the service life of the pipe and avoid water leakage due to pipe damage. Atomizing fan-shaped nozzle 10: Fixed at the bottom of PVC-U branch pipe 8, evenly distributed along the axis of PVC-U branch pipe 8, and installed at an angle. It can convert the water source transported by PVC-U branch pipe 8 into mist particles, increase the contact area with dust, improve dust suppression efficiency, and ensure that all areas of the dry beach can be covered by water spraying to avoid dust suppression blind spots. The angled installation can make the water spraying trajectory conform to the dry beach slope, which can not only avoid tailings loss caused by water flow erosion, but also ensure that the water spraying is accurately applied to the surface of the dry beach. Main pipe clamp 11: Fixed to the top of the main support 2, used to fix the PVC-U main pipe 9, and located at both ends of the PVC-U main pipe 9. It can firmly fix the PVC-U main pipe 9 to the main support 2, prevent the pipe from shifting or shaking due to water flow impact or wind force, ensure the sealing of the pipe connection, avoid water leakage, and at the same time, the fixing at both ends can limit the axial movement of the pipe and ensure the overall stability of the pipe system. Branch pipe clamp 12: Fixed at equal intervals on the top of the auxiliary support 4 to fix the PVC-U branch pipe 8. The equal interval distribution can make the PVC-U branch pipe 8 evenly stressed, avoid damage caused by local stress concentration due to uneven fixing points, and at the same time ensure that the PVC-U branch pipe 8 remains horizontal, ensuring smooth water flow in the pipe and avoiding uneven water distribution due to pipe tilt. Branch solenoid valve 13: Fixed at the intersection of PVC-U branch pipe 8 and PVC-U main pipe 9, and connected to outdoor rainproof electrical control cabinet 6 via cable. It can accurately control the water supply between PVC-U main pipe 9 and PVC-U branch pipe 8, realize independent control of water spraying for each branch pipe, and respond to dust suppression needs in a timely manner in conjunction with the instructions of the electrical control cabinet, avoiding water waste caused by ineffective water spraying. At the same time, it is easy to shut down individually when a single branch pipe fails, without affecting dust suppression operations in other areas. Horizontal centrifugal pump 14: Located on one side of the device, the input end is connected to the external water supply pipe, and the output end is connected to the main water inlet pipe of the PVC-U main pipe 9. It can provide power for the entire pipeline transportation system, pressurize the external water source and deliver it to the PVC-U main pipe 9, ensuring that the water source can be smoothly delivered to the spray points in the entire dry beach area, avoiding poor atomization effect of the nozzles or insufficient water spraying range due to insufficient water pressure. At the same time, it is located on one side of the device to facilitate connection with the external water supply pipe, reducing the complexity of pipeline layout. Humidity sensor 15: It is fixed on the main bracket 2 by the sensor bracket 16, facing the dry beach. It is equipped with a display screen. Facing the dry beach, it can accurately collect the air humidity data of the dry beach surface, ensuring the accuracy of the monitoring data and providing a reliable basis for the electrical control cabinet to determine whether to start dust suppression. The display screen makes it easy for maintenance personnel to view real-time data on site and understand the humidity of the dry beach in a timely manner. Fixing it on the main bracket 2 can prevent the sensor from shifting due to ground vibration or tailings accumulation. Sensor bracket 16: Fixed on the main bracket 2, the top is used to fix the humidity sensor 15, the bottom is connected to the main bracket 2, and the bottom of the sensor base 18 is also associated with the bracket. It can raise the humidity sensor 15 to a suitable height, avoid dry dust directly covering the sensor probe and affecting the monitoring accuracy, and provide a stable installation platform for the sensor, reduce the impact of external interference on the sensor, and ensure that the sensor can continuously and stably collect data. Wind speed sensor 17: Fixed on the top of sensor base 18, with an unobstructed setting. The unobstructed state ensures that the sensor accurately captures the real-time wind speed in the dry beach area, avoiding deviations in wind speed monitoring data caused by obstruction. This provides an accurate basis for the control cabinet to judge the dust risk, thereby ensuring that dust suppression operations are started under appropriate wind speed conditions and improving the dust suppression effect. Fixing it on sensor base 18 ensures the stability of sensor installation and reduces the impact of vibration on monitoring accuracy. Sensor base 18: Fixed on the sub-support 4, the top is used to install the wind speed sensor 17, and the bottom is connected to the sensor bracket 16. It can provide a stable mounting carrier for the wind speed sensor 17, ensuring that the sensor is at a suitable height and in an unobstructed position. At the same time, by connecting with the sensor bracket 16, the relative positions of the wind speed sensor 17 and the humidity sensor 15 are fixed, which facilitates the two to collect environmental data together and provide comprehensive environmental parameter references for the electrical control cabinet.
