Description

Technical Field

[0002] Dewatering water is the sewage gushing out from the coal seam during the coal mining process. The water quality characteristics are mainly determined by the underlying characteristics of the coal mine and the mining method. Therefore, the water quality is extremely unstable, with high hardness, salinity, iron and manganese, and may also carry a large amount of inorganic suspended solids. However, its COD, microorganisms and total dissolved solids content are generally low, and the output is often large. Therefore, it is a wastewater with high reuse value. Therefore, it is very necessary to have a wastewater treatment device for mine dewatering water. For the existing wastewater treatment devices for mine dewatering water, most of them add flocculants to the wastewater and then stir to make the impurities in the sewage settle.

[0031] During use, first turn on the motor 15. The motor 15 drives the stirring rod 7 to rotate. The rotation of the stirring rod 7 drives the stirring rod to rotate, and the wastewater and flocculant are mixed. The rotation of the stirring rod 7 drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the first rotating rod 14 to rotate through the second bevel gear 13. The rotation of the first rotating rod 14 drives the first pulley 16 to rotate.

The wastewater after iron removal drops onto the surface of the guide plate 28 along one side of the L-shaped plate 27. Under the action of the guide plate 28, the wastewater enters the collection box 25. The filter plates 30 on both sides of the collection box 25 filter the wastewater to prevent the iron from being washed off the surface of the L-shaped plate 27 by the water. The filtered water enters the bottom of the third treatment tank 4 through the leakage holes on the surface of the leakage plate 31 and is discharged from the drainage port on one side of the third treatment tank 4. When it is necessary to clean the iron inside the third treatment tank 4, the magnet 29 is taken out of the third treatment tank 4 through the connecting plate 23. After the bottom of the L-shaped plate 27 loses support, one end of the L-shaped plate 27 moves downward under the action of gravity. The iron on the surface of the L-shaped plate 27 loses the attraction of the magnetic force and drops into the collection box 25 along one side of the L-shaped plate 27. The collection box 25 is taken out of the third treatment tank 4 to recycle the iron.
