Sludge thicking dewatering equipment

[0019] The working process that the present invention carries out concentration dehydration to sludge is as follows:

[0020] After dosing, the sludge that is completely mixed and has a certain flow rate enters the tank (5) under static pressure or pump pressure. Due to the sudden increase of the flow cross-sectional area, the flow rate will slow down sharply. Under the action of gravity, the specific gravity The lighter clear water will float up, and the sludge with heavier specific gravity will sink. Part of the sludge in the floating clean water will further settle into the sludge zone (17) in the thickening zone (3) behind the splitter plate (4), and part of the clear water in the sinking sludge will be concentrated in the thickening zone (3) behind the splitter plate (4). Zone (3) further ascends to Clearwater Zone (6). The diverter plate (4) has two functions: one, to improve the mud-water separation efficiency of the mud inlet; second, to reduce the interference of the mu
