Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coal wastewater treatment equipment, specifically a device that uses a coagulant to rapidly settle coal slime in a sedimentation tank. Background Technology
[0002] In the coal production, transportation, and storage industries, on-site operations generate coal sludge, dust, and coal lumps, leading to numerous problems such as a dirty and chaotic environment, difficulties in personnel access and maintenance, and significant cleaning challenges. Currently, the main approach involves manual sweeping and collection, followed by transportation to a centralized processing site. This requires workers to manually clean and wash the coal, and the wastewater becomes coal-containing wastewater upon contact with water. Alternatively, underground trenches can be constructed for the collection and flow of coal-containing wastewater, but the high coal sludge content in this wastewater places a significant burden on subsequent treatment equipment.
[0003] The industry typically includes coal-containing wastewater treatment equipment. The general process involves collecting the wastewater through ditches, first entering a sedimentation tank for natural settling, and then treating it with an integrated water purifier before reuse or discharge. However, with economic development, national environmental protection requirements are becoming increasingly stringent. Domestic coal ports, freight yards, and coal mines urgently need to strengthen clean production technology innovation. Currently used integrated water purifiers cannot treat coal-containing wastewater with a high proportion of coal sludge to meet national discharge standards after prolonged treatment. They also struggle with adjusting the nozzle angle, leading to uneven spraying and unsatisfactory treatment results. Therefore, we provide a device that uses a coagulant aid to rapidly settle coal sludge in a sedimentation tank to solve these problems. Utility Model Content

[0030] like Figure 2 , Figure 3 and Figure 4As shown, a mixer 502 is fixedly connected to the upper surface of the dosing tank 501. A stirring shaft 503 is fixedly connected to the output shaft of the mixer 502. The stirring shaft 503 passes through the dosing tank 501 and is rotatably connected to it. The dosing mechanism 5 is installed inside the sedimentation tank platform 11. The dosing mechanism 5 can mix the required chemicals. The mixer 502 can drive the stirring shaft 503 to rotate, which mixes the chemical solution inside the dosing tank 501, thus improving the sedimentation effect. A second water passage hole 12 is provided on the upper surface of the sedimentation tank platform 11. Platform 11 is installed inside the outer wall 10 of the sedimentation tank. Staff can observe the inside of the sedimentation tank from the platform 11. The second water passage 12 on the platform 11 facilitates water outflow.

[0033] The first electric telescopic rod 405, the second electric telescopic rod 406, the telescopic hose 408, the mixer 502, the submersible pump 505, and the outlet water pump 8 in this application are all common electrical devices in the prior art, and the universal connection can be made by using a universal joint or a universal shaft. All of these are existing technologies, and their models or specific structures will not be described in detail in this application.
[0034] Working principle: Wastewater from coal mines enters the sedimentation tank's outer wall 10 through the first inlet pipe 2. Guided by the concrete partition wall 9 and the sedimentation tank platform 11, the water flows through the first and second water passages 6 and 12, forming a natural flow path to ensure thorough mixing. After adding the coagulant aid to the dosing tank 501, clean water is injected through the second inlet pipe 504. The mixer 502 is started, driving the mixing shaft 503 to rotate, ensuring thorough mixing of the coagulant aid and water to form a solution. When spraying the solution, the submersible pump 505 extracts the mixed solution, which is then transported through the first delivery pipe 506 to the spraying pipeline 3. The spraying pipeline 3 then transports the solution to the second delivery pipe 13, allowing the solution to be delivered into the retractable hose 408, and finally to the spray nozzle 407. The spray nozzle 407 is driven by the angle adjustment mechanism 4. The system operates by extending and retracting the first electric telescopic rod 405, which pushes the adjusting frame 404 to swing laterally around the mounting bracket 403 axis of the support frame 402. Simultaneously, the second electric telescopic rod 406 extends and retracts, causing the adjusting frame 404 to pitch. The coordinated action of the two rods enables multi-dimensional angle adjustment of the nozzle. Combined with the deformation adaptation of the telescopic hose 408, the liquid covers the entire cross-section of the water flow, ensuring uniform mixing of the coagulant and coal wastewater. The coagulant promotes the flocculation and enlargement of coal slime particles, which quickly settle to the bottom of the pool. After sedimentation, the clear water is discharged through the outlet pipe 1 via the outlet water pump 8. Excess water automatically overflows from the overflow port 7 of the sedimentation tank, maintaining a stable water level in the pool. The mixer 502 and the submersible pump 505 work continuously to ensure uninterrupted supply of liquid. The angle adjustment mechanism 4 dynamically optimizes the spray angle according to the water flow state, forming an efficient closed-loop process to achieve nozzle angle adjustment.
