Description

Technical Field

[0001] The invention relates to the technical field of coal slime water treatment, and in particular to a rough coal slime water treatment device which is convenient for automatic drug addition. Background Art

[0002] Coal slime water treatment adopts sedimentation and concentration by sedimentation equipment, and the bottom flow of the sedimentation tank is recovered by a filter press. The recovered coal slime is dropped to the ground to dry and sold separately, and the overflow of the concentrator is used as production circulating water; since coal slime water has almost no sedimentation ability in its natural state, it is necessary to add an appropriate amount of flocculant to accelerate the sedimentation rate of the coal slime and realize the separation of water and coal slime; however, excessive use of flocculants will not only increase enterprise costs, but also increase the concentration of circulating water, making the circulating water lose its utilization capacity, so it is necessary to reasonably control the amount of flocculant; because when pool water is added, the water flow will disturb the water that has entered the pool before, causing the pool water to stir up chaos, allowing part of the precipitated coal slime to float again, greatly affecting the sedimentation efficiency, so it is necessary to reduce the disturbance of the water flow; because when the pool water is emptied, part of the coal slime is adhered to the bottom of the pool due to long-term backlog and is difficult to be directly extracted, so this part of the coal slime needs to be processed and recovered; therefore, the present invention improves the existing device in view of the above problems.

[0017] Working principle: In this embodiment, the present invention also proposes a method for using a crude coal slime water treatment device that is convenient for automatic dosing, comprising the following steps: Step 1: first, power on all electrical equipment, then connect the water connection pipe 9 to the coal plant's coal slurry water pipeline, and connect the mud connection pipe 12 to the coal slurry pipeline of the filter press workshop, then pour the high-concentration flocculant solution into the liquid storage barrel 19, start the quantitative water pump 18 and the electric valve on the dosing rack through the starter cabinet 17, and start the intelligent control cabinet 15 at the same time and enter the relevant data of the flocculant solution, and then start the concentration detector 13 and the flow detector 14 to prepare for real-time detection of the coal slurry water data entering the device, so as to feed back to the intelligent control cabinet 15, so that it can adjust the quantitative water pump 18 and the electric valve in real time according to the data model, so as to control the amount of flocculant solution input into the water connection pipe 9, realize the ability of intelligent dosing, and achieve the purpose of improving the economic benefits of the enterprise; Step 2: Slurry water is introduced into the device through the water connection pipe 9. The slurry water first passes through the pipe section where the concentration detector 13 and the flow detector 14 are located. At this time, the concentration detector 13 and the flow detector 14 obtain the flow and concentration data of the slurry water and feed them back to the intelligent control cabinet 15. Then the intelligent control cabinet 15 adjusts the flocculant solution and injects the solution into the slurry water through the dosing pipe 20. Then the slurry water and the flocculant solution are mixed and flow into the water inlet pipe 10, realizing the ability of automatic dosing and achieving the purpose of improving the economic benefits of the enterprise. Step three, after the coal slurry water enters the water inlet pipe 10, it will first enter the pressure relief chamber 21. Since the diameter of the pressure relief chamber 21 is much larger than the diameter of the water inlet pipe 10, the water flow will lose some pressure in the pressure relief chamber 21, and then enter the diversion pipe 22 with a smaller diameter. Since multiple diversion pipes 22 share the water pressure at the same time, the water pressure is further reduced until the water flow is ejected from the water outlet 23, and then blocked and dispersed by the baffle plate 24, and falls downward into the groove in the flow receiving frame 25, thereby gradually reducing the falling height of the water flow, controlling the falling speed of the water flow, reducing the impact of the water flow on the liquid surface, realizing the ability to prevent water flow disturbance, and achieving the purpose of increasing the sedimentation speed; Step 4: After the sedimentation tank 2 is full, you can wait for the coal slime in the coal slime water to settle by itself. Since the coal slime water in the natural state hardly settles, the flocculant plays a vital role. The flocculant is mainly a positively charged group, which will approach some negatively charged particles or particles in the water that are difficult to separate, reduce their potential, and make them in an unstable state, so as to settle the coal slime. When the sedimentation is completed, start the mud pump of the filter press workshop, and pump the precipitated coal slime into the filter press equipment through the mud outlet pipe 11, and enter the next process; Step five, after the sedimentation tank 2 is emptied, the coal slime squeezed on the bottom of the tank for a long time is difficult to fall off, resulting in a part of the coal slime cannot be completely removed by direct suction. At this time, the first motor 28 is started to extend the steel rope 29, thereby lowering the mud scraper frame 30, and then the second motor 31 is started to drive the driven gear sleeve 33 to rotate through the active gear 32, thereby driving the flow receiving frame to rotate, and then driving the articulated frame to rotate through the connecting column 27, thereby driving the mud scraper frame 30 to rotate around the middle column 4, so as to finally scrape the coal slime on the bottom of the tank and make it fall into the sewage collecting tank 3, and then be pumped away by the mud pump, thereby realizing the ability to fully recover the coal slime and achieving the purpose of improving the economic benefits of the enterprise.
