The utility model provides a combustion chamber tile which comprises a tile body, the tile body is provided with a first surface and a second surface which are oppositely arranged, and a first cooling layer close to the first surface and a second cooling layer close to the second surface are further arranged in the tile body. The first cooling layer comprises a plurality of first cooling channels arranged along the first side edge of the tile block body at intervals, and the second cooling layer comprises a plurality of second cooling channels arranged along the second side edge of the tile block body at intervals. The first cooling channel and the second cooling channel adopt one or more of a V-shaped rib channel, a bending channel, a bamboo joint channel, a circular ring channel and a pit channel; compared with a combustion chamber tile which adopts a long and straight cooling channel and internally applies a V-shaped rib channel, a bent channel, a bamboo joint channel, a circular ring channel and a pit channel, the temperature of the outer surface of the combustion chamber tile is obviously reduced under the condition that the same cold air volume is used.

The application discloses a rotary kiln composite lining structure and belongs to the technical field of thermal equipment. The rotary kiln composite lining is designed by a structure of a working layer, a functional layer and an anchoring structure, integrates the concepts of mechanical reinforcement and energy-saving protection, and can realize good structural stability and heat insulation performance. Through efficient reflection of radiant heat by a reflection layer, cooperative heat conduction blocking of a heat preservation layer and a heat insulation layer, resistance to corrosion and stress buffering of a protection layer, and anti-abrasion and high-temperature corrosion resistance of the working layer, a hierarchical heat protection system is formed. In combination with a quasi-flexible connection system in the anchoring structure, the rotary kiln thermal expansion stress and shear stress in the rotating process can be reduced under the premise of ensuring the connection strength, and the overall stability of the structural layer is improved. The rotary kiln composite lining provided by the application has mechanical strength and heat insulation performance, can obtain a relatively long service life, and realizes efficient energy saving of the rotary kiln.

The invention provides a machining device for machining a marine flange forge piece, and belongs to the technical field of marine flange machining. Comprising a machining table, a fixing frame is fixedly connected to the machining table, a servo motor is assembled on the inner side of the machining table, a driving shaft of the servo motor extends to the position above the machining table and is fixedly connected with an electric chuck, and clamping jaws which are evenly distributed are arranged on the electric chuck; a hydraulic telescopic rod is fixedly connected to the outer portion of the top end of the fixing frame, a driving seat is fixedly connected to the tail end of a driving rod of the hydraulic telescopic rod, and a drilling machine is assembled below the driving seat. By arranging the shielding assembly, the side baffles move along with displacement of the drilling machine, shielding is formed on the two sides of the drill bit, then when the drill bit machines a hole in a flange, splashed chippings can be shielded and blocked by the side baffles, and therefore the metal chippings splashed to the outside of the device in the machining process are reduced; and a better working environment is provided for workers.
