QJB4/6-400/3-740/S stamping mixer with lifting device

submersible mixerIt is the use of highly dispersed microbubbles as carriers to adhere pollutants in wastewater, making their density lower than that of floating on the water surface, thus achieving solidification-The process of liquid-liquid separation. In sewage treatment, submersible mixers are widely used to treat wastewater containing small floating particles, algae, and micro flocs, papermaking wastewater, and oily wastewater. According to the different ways of generating microbubbles, their gas submersible mixers are divided into electrolytic submersible mixers, submersible mixers, dissolved gas submersible mixers, biochemical submersible mixers, and ion submersible mixers.

The basic principle of submersible mixer separation is to introduce air into the sewage, which generates a large number of fine bubbles in the sewage and promotes their adhesion to impurity particles, forming a submersible mixer with a density lower than water. Under the action of the submersible mixer, solid particles are achieved-Liquid or liquid-liquid separation.

The contact adsorption mechanism between microbubbles and particles usually has two situations: one is the presence of microbubbles in the middle of the floc, and the larger the floc, the stronger this tendency, which can better retain the bubbles. The second is the adsorption of bubbles and particles, which is caused by the interfacial tension between the two phases. According to the action on gas-solid-The interfacial tension between the liquid and three-phase phases can be used to infer the magnitude of this adsorption force. At the three-phase contact point, the o-contact formed by the gas-liquid interface and the solid-liquid interface is called a contact point.

1： Introduction to the structure and performance characteristics of submersible mixers:

1. The submersible mixer has a compact structure, small volume, and light weight. Simple operation and maintenance, easy installation, and long service life.

2. The blades of the submersible mixer have self-cleaning function, which can prevent foreign objects from entangling and blocking.

3. The use of submersible mixers and aeration systems can significantly reduce energy consumption, improve oxygenation, and effectively prevent sedimentation.

4. The motor winding of the submersible mixer is insulated to Class F with a protection level of IP68. The selection of imported bearings for lubrication and maintenance free, as well as the winding with oil chamber leakage detection and motor overheating protection functions, make the motor work safer and more reliable.

5. Corrosion of tungsten carbide material for mechanical seal friction of submersible agitator, all fasteners are made of stainless steel.
