Basic introduction of QDT submersible mixer waste water low speed plug flow device fertilizer manure Tank Mixer

Model QDT low-speed flow propeller is extensively used for the flow propelling in the oxidizing ditches in the technological process of the water treatment, agitation in various types of bio-chemical tanks and also used in the mixing and flow propelling for freezing prevention in the rivers, landscape water cycling and so on. The low-speed flow propeller consists of the submersible motor, speed-reducing device, vanes, installation system, etc. The roduct is characterized by low power (1.5~7.5KW), low rotational speed(36~135rpm), large diameter of the 

vanes(1000~2500mm), low-speed rotation, production of large-volume flow field and wide scope of service. The swept-back, banana-shaped vanes have the self-cleaning function, being shaped with the use of PU or aluminum alloy through precision casting and having such advantages as light weight, high strength, good resistance against corrosion and so on. Its excellent frictional property can ensure the production of the good damping effect with relation to liquid under the moving state of low rotational speed so as to create the gentle water flow. The series of

products have also. the mixing function apart from the flow propelling and creation of water flow as shown in the drawing. 

Conditionsof Usage 

The highest temperature of the media shall not exceed 40ºC ;

The density of the media shall not exceed 1150Kg/m 3 ;

The scope of the PH value of the media: 5~9;

The depth of submersion shall not exceed 20m.
 

Scope of application

The submersible mixers are mainly used for the purposes of mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment and can also be used as the maintenance equipment for the  landscape water environment; through agitation, they can achieve the function of creating water flow, improving the quality of the water body, increasing the oxygen content in water and effectively preventing the sedimentation of the suspended substances.
