[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0037] In practical use, the static and slow-flowing sedimentation and circulation device for coal-water treatment according to this utility model includes a primary vibration filter assembly 7 and a secondary vibration filter assembly 11. The primary vibration filter assembly 7 is located on the top of the sedimentation separation tank 4 and is equipped with a vibrator. It is mainly used to vibrate the upper grid plate layer 8 and the lower grid plate layer 9 in the sedimentation separation tank 4 when the sedimentation separation system is started. This causes the impurities that are not easy to fall off from the upper grid plate 801 and the lower grid plate 901 to fall off through vibration and then be discharged.

[0038] The secondary vibration filter assembly 11 is mainly used to pump the mud-water mixture in the middle part of the upper grid plate 801 and lower grid plate 901 in the sedimentation separation tank 4 to the secondary vibration filter assembly 11 for filtration by the pneumatic diaphragm pump 14. Then the filtered water returns to the sedimentation separation tank 4, and the mud is discharged through the mud discharge port.

[0039] The level float valve 20 is located on one side of the sedimentation separation tank 4. Its main purpose is to test the level of the liquid and replenish water to achieve the desired effect.

[0040] The upper grid plate 801 and the lower grid plate 901 adopt a double-layer grid plate design. The first layer of the upper grid plate 8 is used to filter larger particles, and the second layer of the lower grid plate 9 is used to filter smaller particles, thereby achieving a better interception effect. At the same time, 10 springs are installed under the fixing plate of the lower grid plate 901. When vibrating, they can effectively remove the impurities adhering to the upper grid plate 801 and the lower grid plate 901.

[0041] The maintenance and sludge inlet 15 is located at the bottom of the sedimentation separation tank 4. It is used to clean and discharge impurities and wastewater in the sedimentation separation tank during equipment maintenance or when the working surface is moved. The auger 16 includes 12 auger blades 17 made of thick iron plates. The auger blades 17 have multiple holes of different sizes, which can effectively discharge sludge and squeeze out water when rotating. The check valve 23 is located at the outlet of the filter cylinder 6. Its main function is to increase the pressure in the equipment cavity during backwashing to achieve a better backwashing effect.

[0042] Drilling wastewater is treated in three stages: large particles, medium particles, and micro particles. The static and slow-flowing sedimentation and circulation device for coal water treatment described in this utility model is used in specific operations for the above-mentioned different stages. First, the drilling wastewater is transported through the outlet to the sedimentation separation tank 4 of the equipment, where multiple branch outlets 27 are located at the bottom. This design utilizes the outlet pipe 25, the outlet distribution pipe 26, and the outlet 27 to create a slow and meandering flow path, reducing the flow rate of the wastewater and allowing large particles in the fluid to settle. As the amount of wastewater in the sedimentation separation system 3 increases, the liquid quickly spreads upwards. Through the meandering flow and collision adhesion technology, the W-shaped upper grid plate 801 and lower grid plate 901, which are interlaced with zigzag trapezoidal grids, and the microporous irregular packing, the velocity and direction of the fluid change, causing collisions and adhesion within the fluid. This increases the contact area between suspended particles and the fluid, improving the removal efficiency of large particles. When a certain amount accumulates, the auger pneumatic motor 19 drives the sludge discharge auger 16 to operate. The sludge is dewatered through spiral agitation and discharged from the auger sludge outlet 18.

[0043] When the mud content at the bottom of the sedimentation separation system 3 exceeds the standard, affecting the effect of tortuous flow and adhesion, and causing the concentration of floating liquid particles to increase, the pneumatic diaphragm pump 14 transports the high-concentration mud to the secondary vibration filter box 12 of the secondary vibration filter assembly 11. The secondary vibration filter box 12 has a built-in 60-micron metal filter screen 13 for secondary separation.

[0044] The floating oil wastewater inside the sedimentation separation tank 4 is discharged through the overflow pipe at the top of the system; the floating liquid after static and slow tortuous flow and adhesion pre-separation is transported by a pneumatic diaphragm pump to the filter cylinder 6 of the backwash filtration system 5 through the water distribution port distributed at the top of the packing material;

[0045] The backwash filtration system 5 precisely filters the microparticles floating in the sedimentation separation tank 4; the filter core material has a precision of 25 microns; the filtered liquid can be directly supplied to the kilometer drilling rig; effectively protecting the bottom motor of the drilling rig; and extending the service life of the drilling rig.

[0046] Furthermore, the static and slow-flowing sedimentation and circulation device for coal-water treatment described in this utility model is also equipped with a liquid level float valve 20 and a float liquid level switch; it can intelligently start the water replenishment device. It also has a one-button cleaning function, allowing for maintenance and cleaning of the equipment during shutdown or repair. This not only improves maintenance efficiency but also ensures internal cleanliness, preventing the equipment's lifespan from being affected by long-term accumulated dirt; it also makes changing the working face more convenient.

[0047] The liquid filtered by the static and slow-flow sedimentation and circulation device for coal water treatment described in this utility model can be recycled, reducing energy consumption and wear. It effectively solves the problems of water scarcity in coal mines and the treatment of drilling wastewater.

[0048] In summary, by utilizing the above-mentioned technical solution of this utility model and through the optimized and improved design of the product of this utility model, the problems of high-concentration impurities in drilling wastewater, such as oil content, easy clogging, and difficulty in treatment, can be solved. The wastewater is treated in three stages: large particles, medium particles, and micro particles, thereby achieving the beneficial technical effects of effective recycling of water resources and extending the service life of drilling rigs. Moreover, the device has the characteristics of high automation and small size.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
