Reaction stirrer

Abstract

The invention relates to a reaction stirrer enabling raw water mixed with medicament in a water supply and discharge engineering to be reacted slowly. The invention provides a reaction stirrer in which the chemical reaction is performed, meanwhile, by means, flocculate monomers can be mutually combined to form a larger flocculate, then the flocculate is sufficiently deposited to improve the watersupply quality. The reaction stirrer comprises a drive motor, a speed reducer and a stirring pool, also comprises a motor support, a stirring shaft, a stirring paddle and an underwater bearing, wherein, the motor support is fixed at the top of the stirring pool, the drive motor is fixed on the motor support, the stirring shaft is vertically arranged in the stirring pool, the underwater bearing isarranged at the bottom of the stirring pool, a lower end of the stirring shaft is connected with the underwater bearing, the stirring paddle is fixed on the stirring shaft. The stirring paddle of theinvention can stir the raw water mixed with the medicament slowly, on one hand, the raw water can be reacted sufficiently with the medicament, on the other hand, the flocculate monomers can be mutually impacted, contacted and aggregated to form the larger monomer, thereby being convenient for depositing and reducing the foreign matters in the discharge water.

Description

technical field [0001] The invention relates to a reaction mixer, in particular to a mixer for slowly reacting raw water mixed with medicine in water supply and drainage engineering. Background technique [0002] In water supply and drainage projects, sometimes the requirements for water indicators are relatively high. It is not only necessary to separate solid impurities, but also to deal with tiny suspended solids and colloids in raw water. The treatment of tiny suspended solids and colloids often requires chemical treatment, that is, adding chemicals to the raw water to make tiny suspended solids and colloids form large particle flocs to facilitate gravity separation in sedimentation tanks. At present, when carrying out similar treatment procedures, most of them adopt the aging method to ensure the complete reaction after dosing. The problem is that the floc monomer is small in size, resulting in poor flocculation effect and incomplete precipitation. There are still a ce...
