Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment and resource recycling technology, and in particular to a high-efficiency coal mine wastewater reuse equipment. Background Technology

[0002] Coal mining generates a large amount of coal mine wastewater. This wastewater typically contains high concentrations of pollutants such as coal slag, coal slime, suspended solids, and various minerals. If discharged directly without effective treatment, it will not only cause serious pollution to the surrounding water bodies, soil, and other ecological environments, but also lead to a significant waste of water resources.

[0003] Traditional coal mine wastewater treatment equipment suffers from low treatment efficiency, poor treatment effect, and low resource recycling rate. For example, some equipment cannot quickly and effectively separate coal slag and coal slime during the sedimentation stage, leading to an increased burden on subsequent filtration; at the same time, there is a lack of rapid and automated recycling mechanisms for resources such as settled coal slime. With increasingly stringent environmental protection requirements and a greater emphasis on resource conservation, developing equipment capable of efficiently treating coal mine wastewater is of significant practical importance. Utility Model Content

[0004] To overcome the shortcomings of existing coal mine wastewater treatment equipment, such as low treatment efficiency and low degree of automation in resource recycling, the technical problem to be solved is to provide high-efficiency coal mine wastewater reuse equipment.

[0005] The technical solution is: a high-efficiency coal mine wastewater reuse equipment, including a sedimentation tank, a filter tank, a protective cover, an inlet pipe, a connecting pipe, a screw conveyor, a solenoid valve, a meandering pipe, and an overflow pipe. An inlet pipe is installed on one side of the sedimentation tank, a connecting pipe is installed at the top of the sedimentation tank, and a filter tank is installed at the other end of the connecting pipe. Both the sedimentation tank and the filter tank are equipped with protective covers at the top. A coal outlet is provided at the bottom of the sedimentation tank. A screw conveyor is installed near the coal outlet of the sedimentation tank. A solenoid valve is installed at the outlet end of the screw conveyor. An overflow pipe is installed at the end of the connecting pipe that extends into the sedimentation tank, and a meandering pipe is installed at the end of the inlet pipe that extends into the sedimentation tank.

[0006] As a further preferred option, it also includes an outlet pipe and a filter element. The outlet pipe is installed at the top of the filter box, the filter element is installed inside the filter box, and a meandering pipe is installed at the end of the connecting pipe that extends into the filter box.

[0007] As a further preferred option, a through-beam sensor is also included, with the sensor installed near the meandering tube in the sedimentation tank.

[0008] As a further preferred option, signal lights are also included, with signal lights installed on the outer wall of the sedimentation tank.

[0009] As a further preferred option, a W-grid plate is also included, which is installed in the sedimentation tank near the meandering pipe and the overflow pipe.

[0010] As a further preferred option, it also includes a diversion port, with multiple downward-facing diversion ports in the meandering tube inside the sedimentation tank; and multiple upward-facing diversion ports in the meandering tube inside the filter tank.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. This utility model achieves efficient treatment of coal mine wastewater through the coordinated operation of structures such as meandering pipes. The meandering pipes in the sedimentation tank and the filter tank respectively play the roles of slowing down and diverting the flow and distributing water evenly, thereby improving the sedimentation and filtration efficiency. After sedimentation and fine filtration, the wastewater quality is significantly improved and can be directly reused in various stages of the mine, greatly improving the utilization rate of water resources.

[0013] 2. This utility model equipment has a complete coal slime recovery mechanism. Under the automatic control of the through-beam sensor, screw conveyor and solenoid valve, the coal slime accumulated at the bottom of the sedimentation tank can be transported out of the equipment in a timely and efficient manner. After subsequent processing, this coal slime can be recycled as fuel or industrial raw material, realizing the secondary utilization of resources and increasing the economic benefits of enterprises.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example: High-efficiency coal mine wastewater reuse equipment, such as Figures 1-5 As shown, the system includes a sedimentation tank 1, a filter tank 2, a protective cover 3, an inlet pipe 4, a connecting pipe 5, a screw conveyor 7, a solenoid valve 701, a meandering pipe 8, and an overflow pipe 11. The inlet pipe 4 is installed on one side of the sedimentation tank 1, the connecting pipe 5 is installed at the upper end of the sedimentation tank 1, and the filter tank 2 is installed at the other end of the connecting pipe 5. The top of both the sedimentation tank 1 and the filter tank 2 are equipped with protective covers 3. The bottom of the sedimentation tank 1 is equipped with a coal outlet. The screw conveyor 7 is installed near the coal outlet of the sedimentation tank 1. The solenoid valve 701 is installed at the outlet end of the screw conveyor 7. The overflow pipe 11 is installed at one end of the connecting pipe 5 that extends into the sedimentation tank 1, and the meandering pipe 8 is installed at one end of the inlet pipe 4 that extends into the sedimentation tank 1.

[0022] like Figure 4 As shown, a liquid outlet pipe 6 is installed at the upper end of the filter box 2, a filter element 12 is installed inside the filter box 2, and a meandering pipe 8 is installed at one end of the connecting pipe 5 that extends into the filter box 2, so as to further finely filter the wastewater and make the filtered clean water available for use in the mine.

[0023] like Figure 3 As shown, a through-beam sensor 9 is installed near the meandering pipe 8 in the settling tank 1 to monitor the accumulation of coal slime in the settling tank 1 in real time. Once the coal slime accumulates to the point of blocking light, a signal is sent to trigger the coal slime discharge operation, thus achieving automated control.

[0024] like Figure 1 As shown, indicator lights 101 are installed on the outer wall of the settling tank 1, which visually display the operating status of the device through different colors. Green indicates normal operation, while red indicates a fault or the need for operations such as coal slime discharge, making it convenient for operators to keep track of the device's status in a timely manner.

[0025] like Figure 3 As shown, a W-shaped grid plate 10 is installed between the sedimentation tank 1 and the meandering pipe 8 and the overflow pipe 11, which can effectively block the rise of larger suspended solids and slag in the wastewater, and further improve the sedimentation effect.

[0026] like Figures 2-5 As shown, the meandering pipe 8 inside the sedimentation tank 1 has multiple downward-facing branch ports 801; the meandering pipe 8 inside the filter tank 2 has multiple upward-facing branch ports 801. The different branch ports 801 of the meandering pipe 8 in the sedimentation tank 1 and the filter tank 2 respectively play the roles of slowing down the flow and distributing water evenly, thereby improving the sedimentation and filtration efficiency.

[0027] Coal mine wastewater enters the settling tank 1 through the inlet pipe 4 and the meandering pipe 8 inside. The collision and deceleration effect of the meandering pipe 8 causes the wastewater to enter the settling tank 1 at a lower flow rate. The diversion port 801 faces downwards, causing coal slag to be flushed to the bottom of the settling tank 1, achieving a faster sedimentation effect. The wastewater mixes with the flocculant pre-placed in the settling tank 1, causing coal sludge to gradually accumulate at the bottom of the settling tank 1. As the wastewater level gradually rises, the W-grid plate 10 blocks the rising particles, making it difficult for them to pass through. When the water level reaches the overflow pipe 11, the wastewater enters the overflow pipe 11 and then flows into the filter box 2 through the connecting pipe 5. The meandering pipe 8 of the filter box 2, with its diversion port 801 facing upwards, ensures that the wastewater is evenly dispersed, preventing impurities from concentrating and impacting the filter element 12. After further filtration by the filter element 12, the wastewater entering the filter box 2 can flow out from the outlet pipe 6 for reuse in the mine. When the coal sludge gradually accumulates at the bottom of the sedimentation tank 1 and blocks the through-beam sensor 9, the through-beam sensor 9 immediately transmits a signal to the device. Upon receiving the signal, the device closes the inlet pipe 4, opens the solenoid valve 701 installed at the outlet end of the screw conveyor 7, and then starts the screw conveyor 7. The screw conveyor 7 transports the coal sludge at the bottom of the sedimentation tank 1 out of the sedimentation tank 1. After subsequent processing, the coal sludge can be recycled and reused.

[0028] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation in order to cover all variations and equivalent structures and functions.
