CLJJ Mechanical Mixing Clarifier
Mechanical accelerating clarifier mixing and mud scraper are used in accelerated clarifiers of water supply projects. The raw water mixture that has been put into the coagulant and the active sludge in the clarifier form a sludge reflux and contact reaction through the lifting effect of clarification and stirring to complete the reaction.
There are electric blenders in the center of the pool and an electric mud scraper at the bottom of the pool. In addition, it is also equipped with a water inlet system, a mud discharge system and other auxiliary equipment.
In actual operation, after the raw water enters the annular triangular distribution tank from the water inlet pipe, it enters the first reaction chamber through the water distribution hole at the bottom of the tank, where it mixes with the reflux sludge in the separation chamber and completes the mixing and reaction process of the agent and water; after mixing The water with sludge is lifted to the second reaction chamber by the impeller on the stirring device, and the contact flocculation is completed in the first reaction chamber and the second reaction chamber. A guide plate is provided in the second reaction chamber to eliminate the rotation of the water flow caused by the lifting effect of the impeller, so that the water flow flows smoothly into the separation chamber through the guide chamber. The guide chamber is also provided with a guide plate. Here the water and chemicals complete the coagulation process and are rectified. The upper part of the separation chamber is the clean water area, and the clean water flows upward into the water collection tank and outlet pipe. The lower part of the separation chamber is a layer of suspended sludge. Most of the sinking sludge flows back into the first reaction chamber along the backflow gap at the bottom of the cone to re-contact with the raw water for flocculation reaction. A small part is discharged into the sludge concentrator and concentrated to a certain concentration. Finally, it is discharged out of the pool to save Quantity consumption. Drainage pipes are provided on the annular triangular water distribution tank to eliminate air brought into the incoming water. The reagent can be added to the first reaction chamber, or to the annular triangular water distribution tank or water inlet pipe.
