The inner hollow of above-mentioned top cover; Described bell is fixed with the water inlet pipe and outlet pipe that are all connected with the inside of top cover and communicate.
The upper surface of above-mentioned top cover is higher than the upper surface of foundation ring.
Above-mentioned top cover is circular cone shape; The small end face of described top cover is towards foundation ring; Described top cover is coaxial with foundation ring.
Above-mentioned foundation ring comprises and linking into an integrated entity and orthogonal enclosure and back-up ring; Described back-up ring is parallel with the small end face of top cover.
Reinforcement is provided with between above-mentioned enclosure and back-up ring.
Above-mentioned fire-resistant lid is piled up by polylith refractory brick and is formed.
Above-mentioned bracing frame comprises three tie-beams in 120 degree of circle distribution; Described each tie-beam is all fixedly connected with the upper surface of enclosure with the large end face of top cover.
Above-mentioned slag notch is positioned at the top of discharging opening.
The diameter of above-mentioned slag notch is less than the diameter of discharging opening.
The utility model has positive effect: (1) the utility model utilizes bracing frame to be supported by fire-resistant lid, its Stability Analysis of Structures, is not easy to occur collapsing; (2) the utility model only arranges water inlet pipe and outlet pipe on top cover, while cooling range reduces, also ensure that the control effects of temperature is better; (3) top cover of the present utility model is higher than foundation ring, greatly can strengthen the stability of bell domes; (4) the utility model utilizes refractory brick to pile up on bracing frame, greatly can save the use amount of refractory brick, reduces manufacturing cost; (5) bracing frame of the present utility model only need utilize three tie-beams just can realize very high support strength, manufactures simple.
