Stainless steel submersible mixer has the functions of stirring sewage, mixing sludge, promoting the flow of water medium, preventing sludge from settling, and increasing the flow rate at the bottom of the pool. The mixer is generally a submersible electromechanical device that is directly driven by the motor to rotate the impeller, with medium and high rotational speed, small diameter and three-bladed impeller, which is mainly applied to anaerobic tank, anoxic tank, regulating tank, selecting tank and sludge tank in sewage treatment plant;
Pusher is directly connected by the motor deceleration mechanism, drive the impeller rotation of the electromechanical integration of the submersible device, low speed, large diameter, two-blade impeller, mainly used in sewage treatment plant aeration pool that is aerobic pool, and sometimes also used for anaerobic pools, anoxic pools.
Range of application
Submersible mixers are mainly used for mixing, slackening and circulation in municipal and industrial wastewater treatment processes, as well as for the cultivation of landscape water environments protect, through the impeller rotation movement to achieve the effect of creating water flow, improve water quality, increase oxygen content in water, effectively prevent the deposition of suspended matter.
Submersible miniature speed reducer mechanism is a compact structure of two-stage transmission and adopts high-strength materials, high machining precision, high standard assembly and other means to meet the design requirements to achieve the volume miniaturisation, transmission of high torque, high performance and efficiency of technical performance. Make the transmission more reliable, stronger impact resistance. The structure not only makes the total volume of the thruster reduced by 32%, mechanical efficiency increased by 6.7%.
Use Conditions
1. The temperature of the stirring medium is generally 0°C-40°C;
2. The scope of PH value of the medium: 5-9;
3. The density of the medium shall not exceed 1150Kg/m 3;
4. The depth of submersion shall not exceed 20m.
Reference For Type Selection
The type selection of submersible mixer is a rather complicated job. The correctness of the type selection will directly affect the normal usage of the equipment. The principle for the type selection is to enable mixer to give full play to its mixing function in the appropriate volume. This standard can generally be determined by the flow velocity. In line with the different technological requirement of the sewage treatment, the optimum flow velocity for the mixer type selection shall ensure the velocity range of 0.15~0.3m/s.
Before selection
①should determine the application place of submersible mixer, such as: sludge tank or biochemical tank;
②medium, such as: suspended matter content, temperature, PH value, etc;
③Pool size and installation method, and also considering energy saving factors, because it will affect the operation cost of the user in the future. Refer to the flow field diagram of the submersible mixer below.
Precautions For Selection
1、Application
2、Pool size
3、Media properties, viscosity, density, solid content, etc.
Warning:
The submersible mixer must completely submerse in the water;
The submersible mixer cannot operate in the inflammable, explosive, highly corrosive and high-temperature environment;
The minimum dive depth of the submersible mixer is 900mm.
The supporting power required by the mixer is determined according to the volume size, the density, viscosity and mixing depth of the mixing liquid, and one or more mixer should be used according to the specific situation. Please contact us, for the selection questions.
