Description

Combined efficient mixer

Technical Field

The utility model relates to a water treatment equipment, especially a modular high-efficient blender.

Background

The flocculating agent PAM and the dilute slurry water are quickly and uniformly mixed and then enter flocculation equipment, and in the flocculation equipment, tiny destabilized particles in the dilute slurry water gradually form large floccules.

The mixing modes of the flocculant PAM and the dilute muddy water are mainly three:

(1) The water pump mixing and water pump mixing is to feed the flocculating agent PAM on a water inlet or a water inlet pipe of the water pump and adopt the high-speed rotation of a water pump impeller to fully mix the flocculating agent PAM and the dilute slurry water. The water pump mixing effect is good, no additional mixing facility is required to be built, and power is saved. The problem that this mode exists is, the water pump mixes the back, and the thin mud water that mixes there is flocculating agent PAM need just can get into flocculation equipment through longer pipeline, and at this process, the partial big flocculating constituent that small destabilizing particle formed in the thin mud water is destroyed, becomes little flocculating constituent, influences the flocculation effect.

(2) Pipeline mixing is commonly used with tubular static mixers. A plurality of mixing blades are fixedly arranged in the tubular static mixer and are arranged in a crossed mode according to a certain angle. When the flocculant PAM and the thin sludge water flow through the pipe static mixer, they are divided and turned several times, forming a vortex, and are mixed. The tubular static mixer has simple structure and no power consumption. The method has the problems that a tubular static mixer is used, so that the flocculating agent PAM and the dilute slurry water are not uniformly mixed, and the flocculating agent PAM is wasted; a plurality of tubular static mixers are connected in series, the flocculating agent PAM and the dilute slurry water are uniformly mixed, but in the process, a part of large flocculating constituents formed by micro destabilizing particles in the dilute slurry water are destroyed and changed into small flocculating constituents, and the flocculation effect is influenced.

(3) Mechanical mixing is to install mechanical stirring equipment in a mixing tank and to carry out intensive stirring by driving of a motor. The mechanical mixing effect is usually better, the stirring intensity can be adjusted at any time, and the use is flexible and convenient. The method has the problems that the mixing time is long, part of large flocculating constituents formed by micro destabilizing particles in the slurry water are destroyed and changed into small flocculating constituents in the mixing process, the flocculation effect is influenced, and in addition, mechanical equipment consumes much power and is relatively complex.

Flocculating agent PAM and thin mud water intensive mixing just do not influence the flocculation effect, are the utility model discloses the problem of proposing the solution.
