Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, and more specifically, it relates to a corrosion-resistant permanent magnet submersible mixer for sewage treatment. Background Technology

[0002] A permanent magnet submersible mixer is a mixing device that directly couples a permanent magnet synchronous motor to an impeller and is designed to operate submerged in liquid for extended periods. Its main function is to push and stir mixtures of sewage and sludge, preventing sedimentation, maintaining uniform mixing, and enhancing mass and heat transfer. During sewage treatment, to ensure stable operation, protective mechanisms are typically installed on the outside of the mixing components. After a period of use, these protective mechanisms may come into contact with hard debris in the sewage, necessitating replacement. However, replacing commonly used mixer protective mechanisms can be difficult due to the sewage, making disassembly and replacement challenging. Utility Model Content

[0009] As a preferred embodiment of this utility model, the protective cover further includes: a locking block, wherein the number of locking blocks is set to two, and the locking blocks are symmetrically and integrally disposed on one side of the fixed socket; the locking blocks fit into the fixed slot; and a locking groove is formed on the top of the locking block; the locking groove fits into the fixed insert.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By agitating the wastewater with the mixing blades, the protective cover can effectively isolate external impurities and block the impact of larger foreign objects, providing comprehensive and reliable protection for the mixing blades, ensuring stable and reliable operation, and extending the service life of the equipment.

[0011] When the protective cover is damaged due to long-term use or requires routine maintenance, there is no need to disassemble the entire machine or use large tools. Simply insert a hex wrench into the hexagonal groove at the top of the fixing screw, and manually rotate the wrench to drive the fixing screw to rotate, thereby driving the fixing slider to move axially. This allows the fixing blocks on both sides to smoothly disengage from the locking groove, and the protective cover can be quickly removed for maintenance or replacement. The entire operation process is simple and quick, significantly reducing maintenance difficulty and time costs, and improving the maintainability and overall operating efficiency of the equipment.
