Submersible Mixers Description
Dagyee explosion-proof submersible mixer is a special safety-grade underwater stirring equipment independently developed for flammable, volatile and explosive special industrial sewage working conditions. Different from ordinary civilian mixers, this equipment adopts full industrial explosion-proof sealing structure and isolated electrical cavity design, which completely isolates internal electrical components from external flammable and volatile water media, effectively preventing electric spark leakage and eliminating explosion safety hazards. The whole machine is made of high-strength anti-spark stainless steel material, matched with upgraded explosion-proof dual mechanical seal and IP68 deep waterproof grade, supporting 24-hour continuous safe diving operation in high-risk petrochemical sewage environments. The optimized anti-blocking hydrofoil impeller avoids oil sludge adhesion and fiber winding, maintaining stable and uniform water circulation and stirring effect in complex flammable wastewater.
Submersible Mixers principle
Component
- Motor
- Upper bearing
- Seal monitoring&indication
- Solids deflection ring
- Mechanical seal
- Axial flow propeller
- Bracket
- Control System
- Corrosion resistant shell
The operating principle centers on converting electrical energy into controlled hydrodynamic flow. The motor drives an impeller (typically a three-blade propeller or specialized mixing disc) that rotates at optimized speeds. This rotation creates a powerful axial or radial flow pattern, generating a directional current within the vessel. This current ensures complete circulation, preventing sedimentation, maintaining solids in suspension, equalizing temperature and concentration gradients, and enhancing chemical or biological reactions by ensuring uniform contact between components.

Energy-saving Submersible Mixers Selection
This explosion-proof submersible mixer is exclusively suitable for high-risk industrial scenarios such as petrochemical plants, oil refineries, natural gas enterprises and coal chemical factories, targeting flammable, volatile and oil-containing wastewater treatment. It solves the defect of high energy consumption of traditional explosion-proof mixing equipment, equipped with high-efficiency energy-saving explosion-proof motor, which reduces invalid power consumption on the premise of meeting industrial explosion-proof safety standards. It is the only safe and energy-saving preferred stirring equipment for special dangerous sewage treatment projects, perfectly balancing safety performance and operating cost control.
Submersible Mixers Installation Method
Dagyee explosion-proof submersible mixer adopts heavy-duty full explosion-proof guide rail lifting installation system as standard. All installation accessories including guide rails, brackets, fasteners and bottom bases are made of anti-static and anti-spark special metal materials, which will not generate impact sparks during water flow impact and equipment operation. The modular lifting structure supports free underwater lifting, inspection and maintenance without draining tank water or shutting down the dangerous treatment system, ensuring continuous safe operation of the project. For special limited-space explosion-proof tanks, customized fixed anti-explosion suspension installation schemes can be provided to adapt to special tank structure requirements.
