Summary: | The utility model relates to the technical field of fluidized bed boiler structures, in particular to a clamping groove type anti-overturning hood. An existing air cap and an existing inner sleeve arefixed through a spot welding structure with an external clamping groove to prevent a cap head from falling off, but due to poor weldability of a casting, welding cracks are prone to being generated to cause damage and falling off, the welding position is low, welding is not suitable for being carried out, and welding is difficult. A plurality of exhaust holes evenly distributed along the circumference are formed in the cap head, a supporting plate used for supporting the cap head is arranged on the circumferential wall of the inner sleeve, a plurality of protruding blocks are arranged on thecircumferential wall of the inner sleeve, an annular boss is arranged at the bottom end of the cap head, and an annular groove is formed in the inner wall of the boss. And a plurality of embedding grooves which are in one-to-o |
