Thickener

The central transmission single (double) pipe mud suction machine is mainly composed of central transmission device, central vertical frame, mud suction pipe, slag scraping plate, truss, scum scraping and collecting device, working bridge, water retaining skirt, scum bucket, etc. When the sludge mixture enters the water inlet tank, it evenly enters the tank through the water distribution hole pipe at the bottom of the tank. Under the action of the water retaining skirt, the water flows slowly and evenly from the bottom of the surrounding tank to the center of the tank in the state of density flow. At the same time, the sludge begins to settle at the bottom of the tank under the action of gravity to form a high concentration primary sludge layer, The separated clarifier flows to the lower part and returns to the surrounding outlet tanks and is discharged out of the tank through the outlet pipe. Under the action of liquid level difference, the activated sludge on the surface of the tank bottom is collected and discharged out of the tank through the orifice on one side of the sludge suction pipe. The heavy emotional sludge is scraped to the sludge pit in the center of the tank by the scraper plate and discharged out of the tank through the sludge discharge pipe. The scum on the tank surface is skimmed into the scum bucket through the scraper device Discharge outside the tank.
