Abstract

The utility model discloses a vertical paddle mixer and belongs to the field of sewage treatment. Traditional mixing equipment is a submersible mixer; a motor and a bracket of the traditional mixing equipment are underwater devices respectively, so that the requirements on a manufacturing process and materials are very high and easiness in damage and inconvenience in maintenance exist. In a tank body of which the ratio of the diameter to the depth is 0.5 to 1, liquid impacts the tank wall to form great reactive thrust and the defects that underwater parts are more, easy to damage and not easy to maintain are remarkable, for solving the problems, a novel vertical paddle mixer is provided; and a motor of the novel vertical paddle mixer is mounted above the tank body and matched facilities such as a hoisting device, a guide rail and a bracket are not needed, so that underwater connecting members are omitted, the simpleness in maintenance is realized and the service life of the motor is greatly prolonged. The vertical paddle mixer is mainly used for mixing liquid in square or circular tank bodies such as a regulating tank, an A tank and a digestion tank; and due to the adoption of unique shaft part and impeller design, the mixing work of the liquid in the tank body with the depth being 10 meters and capacity being 1000m<3> can be finished.

Description

Vertical mixer

(1) technical field:

The utility model relates to a kind of mixer, and particularly a kind of vertical mixer belongs to the mixing plant that uses in the sewage treatment process, and use occasion is regulating reservoir, A pond, digester.

(2) background technology:

Mostly the various sewage mixing plants that use in the prior art at present are submersible type, and its motor, support etc. are parts under water, so very easily damage and safeguard very inconvenience; In the footpath deeply than less than 1 Chi Tizhong; Because the pond bulk area is little, power, the wheel speed of diving mixer are certain, cause the waterpower fluidised form in this pond extremely unstable; The influence of the recoil strength of its blade liquid body bump pool wall generation simultaneously, the life-span of equipment receives serious threat even shortens.

(3) utility model content:

The purpose of the utility model be to prior art in the footpath deeply than existing deficiency and defective in less than 1 circle or dominant shape pond body, provide that a kind of parts under water are few, easy to maintenance, the vertical mixer of long service life.

The purpose of the utility model realizes through following technical scheme: a kind of vertical mixer; Comprise service bridge, motor reducer, vertical shaft, blade, electric cabinet and coupling etc.; It is characterized in that: the design of its vertical shaft makes the installation site of parts such as motor reducer all be positioned at body top, pond; Parts are merely blade and part axis body under water, have prolonged the service life of equipment greatly.In addition, vertical shaft adopts the high-quality seamless steel pipe to process, and has good strength and stiffness; Axial length can reach 8 meters; Be equipped with the design of big blade, make that dark 10 meters, pond hold in the pond body of 1000m3 and still can reach good mixing effect this equipment in the pond, it is dark in the stirring less than liquid in 1 circle or the square pond body to be particularly useful for the footpath; Maximum pond can reach 12 meters deeply, like regulating reservoir, A pond, digester etc.

The utility model compared with prior art has following advantage and beneficial effect: the motor of this vertical mixer and mixing arm are accomplished power through vertical shaft and are transmitted and become body top, pond at the bottom of making the installation site of motor by the pond, corroded by agitated medium; Blade horizontally rotates, and fluid flow pattern is stable in the pond, the good and blade long service life of mixing effect, and stable equipment operation, fault rate is low and be easy to maintenance.

(4) description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: 1-motor reducer, 2-vertical shaft one, 3-coupling, 4-vertical shaft two, 5-blade.

(5) specific embodiment

Below in conjunction with Fig. 1 the structure of the utility model is done further explanation.

Fig. 1 is the structural representation of the utility model, and this equipment comprises motor reducer 1, for equipment operation provides power; Coupling 3, the degree of balance that is used to connect vertical shaft 1 and vertical shaft 24 and adjusts blade, blade 5.Motor reducer is positioned at body top, pond, transmits power through vertical shaft to blade.For the pond is the square pond or the circular pond of 5-12 rice deeply, for ease of transportation and easy for installation, adopts the twin shaft form, and the degree of balance through axial region coupling adjustment blade operates steadily it.In addition, the utility model is broken through traditional paddle restriction, adopts hyperboloid form blade, and diameter can reach 1.8 meters.

Claims

1. a vertical mixer comprises motor reducer (1), for equipment operation provides power; Coupling (3), the degree of balance that is used to connect vertical shaft one (2) and vertical shaft two (4) and adjusts blade; Blade (5) is characterized in that: described motor reducer is positioned at body top, pond, need not boom hoisting, parts are few under water; Its vertical shaft adopts seamless steel pipe to process; Axial length can be to 8 meters; Has good rigidity and intensity; Be applicable to the footpath dark than less than 1 circular pond or square pond in the stirring of liquid, the dark maximum in pond can reach 12 meters, use be combined into anoxic section or the digester in regulating reservoir in the sewage treatment process, anoxic pond, the A/O technology.
