JJ type mechanical agitation the clarifier mixer, mud scraper

Use and introduction

JJ type of mechanical agitation clarifiers mixer, mud scraper is the main equipment of the national machinery to accelerate the clarifier. Commonly used in drinking water, industrial water supply raw water treatment and industrial wastewater tertiary treatment, water softening treatment to the wastewater treatment process in the clarification stage.
Single mixer, into the clarifiers raw water turbidity is generally no more than 1000 mg / L, a short period of time does not exceed 3000mg / L, supporting the mud scraper to enter clarify pool turbidity up to 1000-5000mg / L, a short period of time not more than 10000mg / L of

This equipment installation, maintenance, management; smooth running, safe, reliable, adjustable back flow characteristics.

Structure and working principle

Mixer by adjusting flow device, variable speed drives, mixer spindle to enhance the impeller and mixing blades and other components.
Mud Scraper mainly by the variable speed drive. Drive shaft and scraper rake components, to clarify Pools Trail is less than 19.5m, the mixer shaft hollow shaft, scraper shaft running through it, for sets of axis center drive, pool diameter greater than two diameters 19.5m when separately from the scraper gear pin chainring drive.

The bottom of the mixer impeller blade in the clarification of the pool a reaction chamber to complete the mechanical response, the collision re-adsorption of the original micro-flocs and return sludge alum dosing mixture, the formation of larger floc particles, and then by the impeller to enhance the second reaction chamber, and then flows through the fold to clarify the district were separated, the water rising from the set of pipes leads sludge to clarify the District, the lower back to a reaction chamber, the valve control through the bottom mud by mud scraper scraping sets discharged to the raw water to clarify the effect of the separation.
